DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] The agricultural device 1 shown in FIGS. 1, 2 and 3 comprises a supporting frame 2, which is further divided into a central part 3, a left wing 4 and a right wing 5, wherein the wings 4 and 5 are rotatably attached to the central part 3. Because of the rotatable mounting it is possible to fold the agricultural device 1 into a more compact form, which is important for subsequent transport of the agricultural device 1 on roads. The agricultural device 1 includes at least two rows 6 of working units 7, which are arranged in such a way that their mutual distance 14 is the same along the whole width of the agricultural device 1. In an exemplary embodiment of the invention, the agricultural device is provided with three rows 6 of working units 7. However, even multi-row arrangements with four, five and more sets 6 of working units 7 are possible. In an exemplary embodiment of the invention, the working unit 7 is a ploughshare, although other embodiments of the invention are possible with different working units 7 that are used for soil processing, e.g. by chisels.

[0023] Agricultural device 1 is further provided with two sets of rollers shown in FIG. 4-11, namely the left set of rollers 9 and the right set of rollers 10, wherein the left set of rollers 9 is considered to be the left set from the top view of the device 1 in the driving direction 1a and the right set of rollers 10 is considered to be the right set of rollers from the top view of the device 1 in the driving direction 1a, see FIG. 2. The left set of rollers 9 is attached to the left wing 4 and the right set of rollers 10 is attached to the right wing 5. The sets of rollers 9 and 10 are divided into the front roller 9a and 10a, the rear roller 9b and 10b and they are provided with attachments 13 along their sides, where the inner attachments 13a are located closer to the center of the agricultural device 1 and the outer attachments 13b are located further from the center of the agricultural device 1. The discs 11 are arranged between the attachments 13 of the rollers in such a way that the position of the discs 11a located on front rollers 9a and 10a correspond with the working units 7, see FIG. 2. The number of discs 11b located on rear rollers 9b and 10b differs by exactly one disc 11 from the number of discs 11a located on front rollers 9a and 10a, and they are located in such way that the mutual distance 12 of all discs 11 is the same along the whole width of the agricultural device 1. In an exemplary embodiment of the invention, the number of discs 11b on rear rollers 9b and 10b is higher by one disc 11 than the number of discs 11a on front rollers 9a and 10a. In another exemplary embodiment of the invention, the number of discs 11b on rear rollers 9b and 10b is lower by one disc 11 than the number of discs 11a on front rollers 9a and 10a. Because of this, the soil is evenly processed along the whole width of the agricultural device 1 and no gaps of unprocessed soil appear.

[0024] The sets of rollers 9 and 10 differ from each other, both in their length and in the number of discs 11, which are located on each set. In an exemplary embodiment of the invention, the right set of rollers 10 is longer than the left set of rollers 9 and extends beyond the central axis of the agricultural device 1 in its length. Other embodiments of the invention are possible when the left set of rollers 9 is longer than the right set of rollers 10 and extends beyond the central axis of the agricultural device 1 by its length.

[0025] In an exemplary embodiment of the invention, the left set of rollers 9 is provided with a disc 14 mounted to the inner attachment 13a. The distance of this disc 14 from the nearest discs 11 equals the mutual distance 12 of other discs 11. All discs 11 and the disc 14 attached to the inner attachment 13a are then arranged in regular distances 12 along the whole width of the agricultural device 1. The disc 14 mounted to the inner attachment 13a can then be located in such way that its position corresponds with the position of discs 11a of front rollers 9a and 10a. In another exemplary embodiment of the invention, the disc 14 mounted to the inner attachment 13a can then be located in such way that its position corresponds with the position of discs 11b of rear rollers 9b and 10b.

[0026] Other embodiments of the invention are possible when the right set of rollers 10 is provided with a disc 14 mounted to the inner attachment 13a. The distance of this disc 14 from the nearest discs 11 equals the mutual distance 12 of other discs 11. All discs 11 and the disc 14 mounted to the inner attachment 13a are then arranged in regular distances 12 along the whole width of the agricultural device 1.

[0027] In other exemplary embodiments of the invention, when the left set of rollers 9 is longer than the right set of rollers 10 and is provided with a higher number of discs 11, arrangement of the disc 14 attached to the inner attachment 13a by the left set of rollers 9 is possible. The distance of this disc 14 from the nearest discs 11 equals the mutual distance 12 of other discs 11. All discs 11 and the disc 14 attached from the outside 13a of the attachment 13 are then arranged in regular distances 12 along the whole width of the agricultural device 1. Other embodiments of the invention are possible, in which the right set of rollers 10 provided with a disc 14 is attached to the inner attachment 13a. The distance of this disc 14 from the nearest discs 11 equals the mutual distance 12 of other discs 11. All discs 11 and the disc 14 attached to the inner attachment 13a are then arranged in regular distances 12 along the whole width of the agricultural device 1.

[0028] In an exemplary embodiment of the invention, a total number of nineteen working units 7 on the agricultural device 1 is arranged in three rows 6. This corresponds with the total number of thirty-nine discs 11 and 14 located on rear rollers 9 and 10.

[0029] In an exemplary embodiment of the invention, the agricultural device 1 is provided with two wheels 8, which make transport of the agricultural device on roads easier. However, other embodiments of the invention without transport wheels or with a different number of wheels 8 are possible.

[0030] A device according to this invention can be used for agricultural devices that use discs located on rear rollers for compacting processed soil.
