DETAILED DESCRIPTION

[0066] FIG. 1 shows a plow module for plowing a ground 120, in which plow module a first cutting element 102 in the form of a spherical cap-shaped hollow disk is arranged in the plowing direction in front of a second cutting element 105, one behind the other, in the form of a flat plate. The first cutting element 102 is provided for cutting the side surface of a soil ridge, whereas the second cutting element 105 arranged after the first cutting element 102 is designed as a flat disk which cuts the bottom of the furrow. Both cutting elements 102, 105 are joined together as a plow module by means of a support structure 4, 5. The support structure 4, 5 can be attached to a base frame (not shown), the second cutting element 105 being connected in an articulated manner to the first cutting element 102 via the support structure 4 thereof.

[0067] As shown in the base structure of the plow module 1 according to FIG. 1, a rotatable first cutting element 102 having a revolving, cambered first cutting edge 103 having a first cutting region 104 is arranged on a first support structure 4 and is designed in such a way that, when moving the support structure 4 on the ground 120 along the plowing direction 110, a lateral region 202 (see FIG. 2) of a soil ridge 201 of the ground 120 can be cut by means of a first cutting region of the first cutting edge 103, as shown in FIG. 2. The plowing direction 110 is defined as the direction along which the plow device 2 is displaced over the ground 120. A second cutting element 105 having a second cutting edge 106 having a second cutting region 107 is arranged on a second support structure 5 which is detachably connected to the first support structure 4 and is pivotable relative to the first support structure. The second cutting element 105 is designed in such a way that, when moving the support structure 5 on the ground 120 in the plowing direction 110, a bottom region 203 of a soil ridge 201 of the ground 120 can be cut off by means of a second cutting region of the second cutting edge 106, the second cutting element 105 being arranged in the plowing direction 110 relative to the first cutting element 102 such that the second cutting region is arranged after the first cutting region in the plowing direction. The second cutting region is thus spaced apart from the first cutting region by the distance x. Positioning actuators 26 (26.1, 26.2 and 26.3) for adjusting the angle of the cutting elements 102, 105 (see FIGS. 6 to 9) have been omitted for the sake of simplicity of illustration.

[0068] Since during plowing the base frame 3 of the plow module 1 is pressed with the first and second support structures 4 and 5 in the direction of the separating surface 121 of the ground 120, the first cutting element 102 is also pressed in the direction of a separating surface 121 so that the first cutting element 102 is maintained in the desired ground depth during plowing.

[0069] FIG. 2 shows a schematic representation of the substantial functional elements of a plow device according to an embodiment of the present disclosure during a plowing operation. Said FIG. 2 shows the correct spatial arrangement of the first and second cutting elements 102 and 105 as well as the formation and turning of soil ridges 201. The other components of the associated plow device 2 are not shown for the sake of clarity.

[0070] As shown in FIG. 2, so-called soil ridges 201 are cut out from the ground 120 during plowing. A soil ridge 201 has a lateral region 202 along which the first cutting element 102 cuts. Furthermore, the soil ridge 201 has a bottom region 203 which connects the two lateral regions 202 and is separated from the ground 120 by means of the second cutting element 105 which is shown in this case by way of example as a fixed cutting blade 6 in the shape of a double L. Correspondingly, the ground 120 has a separating surface 121, the so-called furrow base 121, on the bottom region 203 of the soil ridge 201. After the soil ridge 201 has been cut out, the furrow wall 122 can be seen in the ground 120, from which furrow wall the lateral region 202 of the soil ridge 201 was detached. The bottom region 203 thus defines the lowermost horizontal surface of the soil ridge 201 in the vertical direction at the time of separation from the ground 120. The lateral regions 202 of the soil ridge 201 define the lateral wall regions of the soil ridge 201 at the time of separation from the ground 120.

[0071] As shown in FIG. 1, the support structures 4 and 5 for the two cutting elements 102 and 105 are designed in such a way that at least the first cutting element 102 and the second cutting element 105 are firmly connected to the base frame 3 of a plow device 2. The first support structure 4 can be attached to a tractor via the base frame 3 of the plow device 2 in order to accordingly drive the cutting elements 102, 105 along the plowing direction 110. The plow module 1 has, for example, the first and second support structure 4, 5 which can be designed to be fixed or pivotable via joints.

[0072] The first and the second support structure 4 and 5 thus form a rigid attachment structure for the cutting elements 102, 105. The cutting elements 102, 105 are fixed to the support structures 4, 5 in such a way that no relative movement between the positions of the cutting elements 102, 105 is possible during plowing. If, according to the disclosure, the second cutting element 105 is pressed in the direction of the ground 120 due to the cutting of the soil ridge 201, the first cutting element 102 is also pressed into the ground 120 at the same time, since the two support structures 4, 5 are firmly connected to one another.

[0073] The first cutting element 102 and the second cutting element 105 are rotatably attached to the corresponding support structure 4 or 5. Correspondingly, the first cutting element 102 has an axis of rotation 108 about which the cutting element 102 rotates. The second cutting element 105 forms a second axis of rotation 109 about which the second cutting element 105 rotates. The first cutting element 102 and the second cutting element 105 are designed in this case, for example, as a spherical cap-shaped coulter disk or as a flat disk and have a circular revolving line. The corresponding revolving first cutting edge 103 and the second cutting edge 106 are designed along the revolving line. The lateral region 202 of the soil ridge 201 is separated from the furrow wall 122 of the ground 120 by means of the first cutting edge 103. The revolving first cutting edge 103 has a cutting region 104. The cutting region 104 is that revolving portion of the first cutting edge 103 which, in the plowing direction 110, comes into contact first with the ground 120 and cuts it. A bottom region 203 of the soil ridge 201 is separated from the ground 120 by means of the second cutting edge 106. The second cutting region of the second cutting edge 106 is that revolving portion of the second cutting element 105 which, in the plowing direction 110, makes second contact with the ground 120 or follows the first cutting element and cuts it. The double arrow 12 in FIG. 2 indicates that the second cutting element 105 is pivotably mounted on the second support structure 5 (not shown here). The pivoting allows adjustment of the angle of attack of the cutting blade 6 in relation to the plowing direction and thus the depth of penetration of the plow module 1 into the ground 120.

[0074] A rotatable disk coulter 13 can be arranged in front of the plow module 1 or connected to it, which disk coulter pre-cuts or opens the ground 120 in front of the vertical, second bar 9 of a cutting blade 6 and the first cutting element 102. This reduces the tensile force required for plowing, as does the wear on the cutting blade 6 and the subsequent first cutting element 102. The cutting blade cuts horizontally and vertically as a double or triple edge.

[0075] The first cutting element 102 is rotated when the plow device 2 moves along the ground 120. In this case, for example, frictional forces cause the cutting element 102 to be moved. The cutting element 102 is dimensioned such that during plowing only the lower half of the first cutting element 102, which is located under the axis of rotation 108, penetrates the ground 120, so that frictional forces with the ground 120 induce the rotation.

[0076] The rotation of the first cutting element 102 also causes the separated soil ridge 201 to be lifted. This is shown in FIG. 2 with the arrows indicating the conveying direction 123 of the soil ridge 201 along the plow device 2.

[0077] The separated soil ridge 201 is in frictional contact with a cutting surface 113 of the cutting element 102. The cutting surface 113 is that surface of the cutting element 102 which is formed within the first cutting edge 103 or is surrounded by it. Furthermore, the cutting surface 113 is that surface which faces the separated soil ridge 201. As shown in FIG. 1, the cutting surface 113 can be formed homogeneously without recesses or elevations.

[0078] Due to the lifting of the soil ridge 201 by means of the rotating cutting element 102, the soil ridge 201 can be conveyed into the adjacent furrow in an energy-efficient manner. This furrow was dug in a previous pass of a plow module as shown in FIG. 2.

[0079] According to FIG. 1, the first cutting element 102 and the second cutting element 105 are attached to the support structure 4, 5 relative to one another in such a way that the cutting region 104 of the first cutting element 102 is spaced apart in the vertical direction from the second cutting element 105 or above the second cutting element 105 when the plow device 3 rests in the working position on the ground 120 or penetrates the ground.

[0080] The rotating cutting element 102 and the second cutting element 105 work together synergistically. On the one hand, a desired plowing depth is kept constant by means of the second cutting element 105, since the cut-off soil ridges 201 press on the second cutting element 105 with a defined compressive force/pull-in force and thus counteract the buoyancy of the rotating cutting element 102. On the other hand, the energetically advantageous effect of the rotating cutting element 102 when cutting the soil ridges 201, in particular the side surfaces or lateral regions 202 of the soil ridges 201, is utilized. Thus, an energy-efficient plow device 2 is provided without negatively affecting the quality of the furrow pattern. In addition, the rotating second cutting element 105 causes the cut-off soil ridge 201 to be pressed in the direction of the first cutting element 102, so that crumbling of the cut-off soil ridge 201 is carried out. Furthermore, due to a lateral force, which is introduced into the first support structure 4 by means of the upstream second cutting element 105, a lateral force induced on the first cutting element 102 during cutting is counteracted, so that easier and better guidance of the plow device 2 with a tractor is made possible.

[0081] The first cutting element 102 and the second cutting element 105 are arranged relative to one another on the first and second support structure 4 and 5 such that the second cutting region 107 of the second cutting edge 106 of the second cutting element 105, which cutting region comprises the front half of the cutting element 105, is at a distance x in the plowing direction 110 after the first cutting region 104 of the first cutting edge 103 of the first cutting element 102. Thus, during plowing, the rotating first cutting element 105 first hits the soil ridge 201 laterally and cuts it off from the remaining ground 120 in an energy-efficient manner with the second cutting edge 106 of the second cutting element 105. The first cutting element 105 then cuts a lateral region 202 of a soil ridge 201 with the first cutting edge 103. The second cutting element 105 distinguishes the furrow wall cut with the first cutting element 102. As a result, the subsequent cutting element 102 of the subsequent module can laterally and vertically cut and turn the soil ridge. The soil ridge 201 is then rotated by the curved shape of the first cutting element 102 and its oblique orientation to the plowing direction and deposited in the adjacent furrow. Thus, the first cutting element 102 and the second cutting element 105 cut the soil ridge 201 in an energy-efficient manner, while being kept at the desired cutting depth by the compressive force acting on the second cutting element 105.

[0082] A region (approx. half a circular disk) of the second cutting element 105 undercuts the soil ridge 201. A further attachment region of the second cutting element 105, on which attachment region an attachment rod/shaft (axis of rotation 109) for attachment to the first support structure 4 is arranged, is designed on the second cutting element 105 on the side facing away from the first cutting element 102. Thus, during plowing, the attachment rod/shaft runs in an already prepared furrow, thereby reducing the tensile force of the plow device 2.

[0083] The support structure 4, 5 is designed in such a way that the first cutting element 102 and/or the second cutting element 105 can be adjusted relative to one another along the plowing direction 110 and/or perpendicular, i.e. vertically to the plowing direction 110. For example, the first cutting element 102 can be slidably attached to the support structure 4 by means of bolt connections 115 which can engage in elongated holes 116 in the first support structure 4. By adjusting the distances between the cutting element 102, the second cutting element 105, and the support structure 4, 5 along the plowing direction 110, the plow device 3 can be adjusted to special conditions of different ground types and used in an efficiency-optimized manner. Furthermore, the elements can be readjusted if the elements warp after the plow device 2 has been used.

[0084] Furthermore, the support structure 4, 5 can be designed in such a way that the first cutting element 102 can be adjusted relative to one another along a directional component of the first axis of rotation 108, and the second cutting element 105 can be adjusted along a directional component of the second axis of rotation 109. In particular, an angle between the first axis of rotation 108 and the second axis of rotation 109 can be adjusted. The first cutting edge 103 runs in a first cutting plane, while the second cutting edge 106 runs in a second cutting plane. The first cutting element 102 and the second cutting element 105 are attached relative to one another on the corresponding support structure 4 or 5 in such a way that the first cutting plane and the second cutting plane are not designed to be parallel and are at an angle to one another. For example, an angle between the first axis of rotation 108 and the second axis of rotation 109 is less than 90°, in particular between 45° and 80°.

[0085] Accordingly, with the flexible attachment of the cutting element 102 and/or the second cutting element 105 to the support structure 4 and 5, a distance between the cutting region 104 of the first cutting edge 103 of the cutting element 102 and of the second cutting edge 106 of the second cutting element 105 can be adjusted.

[0086] FIG. 3 shows a plow module 1 according to an embodiment of the present disclosure, in which the second cutting element 105 is alternatively designed as a rotating disk 16 or as a fixed cutting blade 6.

[0087] The first cutting element 102 and/or the second cutting element 105 can be attached to the corresponding support structure 4 or 5 in a pivotable manner, for example by means of a joint, so that an angle between the first axis of rotation 108 and the second axis of rotation 109 can be adjusted and fixed in a desired position. This possibility is indicated here by way of example by a hydraulic cylinder or a spindle 15 which connects the second cutting element 105 pivotably mounted in the second support structure 5 to the first support structure 4. The position of the first cutting element 102, which is shown here by way of example as a concave disk having a cambered edge, can also be adjusted in relation to the first support structure 4, for example hydraulically. Such a setting can be used, among other things, to influence the width of the furrow 14 formed or the interaction of the two cutting elements 102 and 105.

[0088] The first cutting element 102 in FIG. 3 has the shape of a spherical cap and, on its first axis of rotation 108, has a corresponding attachment region which is formed in an attachment plane. The revolving first cutting edge 103 runs within the first cutting plane, with the attachment plane being spaced apart from the cutting plane along the axis of rotation 108. The cutting surface 113 of the cutting element 102 is designed between the revolving first cutting edge 103 and the attachment region.

[0089] FIG. 4 is a representation of a plow device 2 according to the disclosure as a seedbed plow device, on the base frame 3 of which three plow modules 1 according to the disclosure are shown by way of example. Each of the three plow modules shown has a first cutting element 102 and a second cutting element 105 trailing thereto, which cutting elements are connected to one another on a first support structure 4 and on a second support structure 5 to form a uniform plow module, with the second support structure 5 being pivotably articulated on the first support structure so that the second cutting element 105 can have an at least small, adjustably fixable angle of attack downwards into the soil through the actuator 26.3 (see FIGS. 6 to 9), in order to exert the necessary pressure on the plow device to remain at the desired plowing depth and thus to ensure that the first cutting element 102 designed as a hollow disk is at the desired depth for cutting off the side of the soil ridge. When plowing in the plowing direction indicated by the arrow 110, the first cutting element 102 having the revolving cutting edge 103 for cutting the sides of the soil ridge is in front of the second cutting element 105 having an also revolving cutting edge 106 for cutting the bottom of the furrow. A first coupling part 20 is used to connect the plow device 2 to a tractor, for example, the first coupling part 20 being connected in an articulated manner to the second coupling part 21 which is generally designed to be bar-shaped. In principle, the second coupling part 21 represents the base frame 3. The plow modules 1 are attached to the base frame 3 by means of joints 19.

[0090] When pulling over the ground 120, a part of the plow modules penetrates the ground 120 up to a structurally predetermined depth and ejects the soil ridges 201 produced in the process. The plow modules 1 are substantially staggered next to one another, so that a plurality of soil ridges are produced according to their number, as can be seen in FIG. 2. After turning, when leaving the first cutting elements 102, these soil ridges 201 come to rest in the furrow 14 formed by the cutting elements 102 lying in front of them, as is shown in FIG. 2.

[0091] And finally, a plan view of a plow device 3 is shown in FIG. 5, in which six plow bodies 24 are arranged in pairs side by side. The double arrow shows that the plow bodies 24 can be exchanged for the plow modules 1 according to the disclosure. This is particularly easy with regard to the assembly work, because the complete plow modules 1 can be exchanged for the plow body 24 originally mounted on the plow device, without the assembly work being appreciably increased. The plow modules 1 according to the disclosure comprise a first, leading cutting element 102 for cutting the sides of the soil ridge and a trailing cutting element 105 for cutting the bottom of the furrow. The second cutting element 105 is attached to a support structure 5, whereas the first cutting element 102 is attached to a first support structure 4. The support structure 4 and the support structure 5 are connected to one another in such a way that the second support structure 5 can be pivoted in order to be able to adjust the angle of attack of the second cutting element 105 with respect to the bottom of the furrow. The first cutting element 102 can be adjusted in several degrees of freedom, so that the adjustment of the plow width on the one hand and the interaction between the first cutting element 102 and the second cutting element 105 on the other hand can be adjusted as a function of the ground parameters and also with regard to further parameters. For example, the first cutting element 102 is adjustably attached to the first support structure 4 by means of a carriage 23, so that its height with respect to the plane which is cut by the second cutting element 105 can be adjusted.

[0092] FIG. 6 is a representation of two plow modules 1 which are attached to a base frame 3 on both sides. The base structure of the plow module 1 described above consists of a support structure 4 to which the first cutting element 102 is attached and to which the second support structure 5 which supports the second cutting element 105 is attached, the first support structure 4 being attached to the base frame 2. A perforated plate 25 is arranged on the first support structure 4 of the first cutting element 102 designed as a hollow disk, which perforated plate allows pivoting of the first cutting element about an axis which is directed substantially perpendicular to the ground to be worked. The pivoting is realized in that an element designed as a disk segment in the form of the perforated plate 25 has bores arranged at a defined grid spacing from one another on the outer circumference. These bores serve to set a pivoting of the hollow disk, i.e. the first cutting element 102, by an angular dimension defined by the grid spacing of the bores. In this embodiment, the cutting angle of the first cutting element 102 is adjusted stepwise. Also shown is a hydraulic actuator 26.3 which can continuously adjust this cutting angle to adjust the cutting angle of the second cutting element 105 when moving through the ground and creating the furrow base. The rest of the base structure corresponds to that which has already been explained, for example with reference to FIG. 1, so that these details are not repeated here. In addition, a connecting element which is designed in the form of a push rod 27 is shown in FIG. 6. The push rod 27 connects all the plow modules attached to the plow device to one another via pivoting plates, so that, during a longitudinal movement of the connecting rod 27, all the plow modules 1 can be adjusted synchronously with regard to their cutting width. The push rod 27 is designed as a square hollow profile and is preferably welded to a sleeve through which a pin representing the corresponding pivot axis passes on the inside.

[0093] FIG. 7 is a representation of the embodiment according to FIG. 6 in a somewhat different perspective in which the actuator 26.3 for adjusting the cutting angle of the second cutting element 105 and the perforated plate 25 can each be clearly seen. The rest of the structure corresponds to that shown in FIG. 6.

[0094] FIG. 8 shows an embodiment of a plow module 1 which corresponds to the base structure according to FIG. 1, but with the possibility of adjusting the first cutting element 102 which is designed as a hollow disk being realized by means of hydraulic actuators 26.1 and 26.2. The actuator 26.1 serves to continuously adjust the cutting angle of the first cutting element 102, which is realized by pivoting the first cutting element 102 about an axis which is directed substantially perpendicular to the ground to be plowed. A second actuator 26.2 is provided, which allows pivoting of the first cutting element 102 about an axis which substantially points in the plowing direction. The respective forces are transmitted by means of articulated lever members, which are known per se to a person skilled in the art and therefore do not need to be explained in more detail here. The rest of the base structure corresponds to that of the plow module 1 according to the disclosure, as already shown and explained in FIG. 1 without the adjustability of the first disk element 102.

[0095] For the sake of completeness, FIG. 9 shows a plow device 2 having six plow modules 1, three each on one side of the base frame 3 or the plow beam, with the base structure otherwise described in FIG. 4. Clearly recognizable are the plow modules 1 provided with actuators 26, by means of which a double-axis pivoting of the first cutting element 102 and a single-axis pivoting of the second cutting element 105 is continuously possible, since hydraulic actuating cylinders are used as actuators.

[0096] FIG. 10 shows a plow device on which six plow modules 1, three on each side of the plow beam 3, are arranged. The respective pairs of plow modules 1 are firmly connected to a connecting element in the form of a push rod 27 via pivoting elements in the form of approximately triangular pivoting plates. With a longitudinal movement of the push rod 27, the plow modules can be adjusted with regard to their cutting width via the pivoting plates. The corresponding movement of the push rod 27 in the longitudinal direction is brought about by means of a third hydraulic cylinder 28, so that in the case of an actuating movement of the actuating cylinder 28, all hydraulic modules can be adjusted synchronously with respect to their cutting width. In a manner known per se, the pivoting of the plow device according to the disclosure relative to the tractor pulling the plow, for which purpose the plow device is attached to the mounting side 30 on the tractor, is laterally adjusted by a first and a second actuating cylinder 29. It is the third actuating cylinder 28 which causes the simultaneous adjustment of the cutting width of the plow device by means of an actuating cylinder 28 which is connected to the push rod 27. The rest of the base structure consists of the first cutting element 102 and the second cutting element 105, which have been described above, and their function and arrangement are therefore not explained again here.

[0097] The rest of the function and the rest of the structure of the plow module 1 as well as the entire plow device have already been described above and are therefore not repeated here.
