DETAILED DESCRIPTION OF THE INVENTION

[0032] The present invention is described in reference to the accompanying drawings and following embodiments that are presented for the purpose of illustration and should not be construed to limit the scope of the invention thereto.

[0033] FIG. 1 illustrates a perspective view of the modular agricultural toolbar in an operational configuration while FIG. 2 illustrates a perspective view of the modular agricultural toolbar in a storage configuration. The embodiment of FIGS. 1 and 2 comprises a core frame, a plurality of pivotal support members, and at least one implement attachment member. A plurality of rail members coupled at a first end by an end plate and at a second end by an abutting member forms the core frame of the agricultural toolbar. The core frame of the modular agricultural toolbar further comprises a sled bracket movably coupled to the plurality of rail members, configured to couple an end of at least one support member and to move along the length of the core frame. In some embodiments, the plurality of rail members of the core frame forms a central channel that spans the length of the core frame. Further, the sled bracket may be partially disposed within the central channel while also coupled to the plurality of rail members. In some embodiments, the core frame may further comprise a stationary bracket disposed within and spanning a length of the central channel, configured to provide structural stability to the core frame.

[0034] In some embodiments of the modular agricultural toolbar, the central channel of the core frame may further comprise a hydraulic piston coupled at a first end to the sled bracket and at a second end to the stationary bracket. The hydraulic piston is configured to anchor the sled bracket to the core frame while still allowing it to move along a length of the core frame. The piston is also configured to extend and retract along an axis of the central channel, transporting the sled bracket in a direction along the core frame's length during a transition between the operational and storage configurations of the agricultural toolbar.

[0035] In another embodiment, the end plate of the core frame may further comprise an attachment point configured to couple a hauling means, including but not limited to ball, pintle, receiver, or weight distribution hitches. In another embodiment, the hauling means may be coupled to the core frame of the modular agricultural toolbar through a clamping mechanism that couples the plurality of rail members from any direction sufficient to secure the core frame to the hauling means.

[0036] In one embodiment of the agricultural toolbar, the abutting member of the core frame further comprises a plurality of attachment points, each configured to couple a farming implement, including but not limited to sprayers, seed drills, planters, rotary tills, strip tills, cultivators, reapers, or harvesters. A person of ordinary skill in the art would appreciate that various agricultural implements may be attached to the abutting member once the implement is scaled or configured for the correct size attachment required to couple the abutting member, if an implement of suitable size is not readily available.

[0037] In another embodiment of the agricultural toolbar, the plurality of rail members of the core frame further comprises at least one pivotal attachment point disposed on the rail member surface at a length from both the abutting member and the central bracket, the pivotal attachment point configured to moveably couple an end of at least one implement attachment member. The pivotal attachment point is further configured to allow rotational movement of the at least one implement attachment member during a transition between the operational configuration and the storage configuration of the modular agricultural toolbar.

[0038] The modular agricultural toolbar further comprises at least one support member coupled at a first end to the sled bracket and coupled at a second end to an attachment point disposed on a surface of the at least one implement attachment member. The at least one support member is further configured to stabilize the implement attachment member during operation and transportation of the agricultural toolbar, while also forming a lever to transfer the force of the central hydraulic piston through the sled bracket and to the implement attachment member, thereby facilitating the movement required to extend or contract the implement attachment member towards or away from the core frame during a transition between the operational configuration and the storage configuration.

[0039] In one embodiment, the modular agricultural toolbar further comprises at least one implement attachment member coupled at an end to a pivotal attachment point of the core frame and having a plurality of implement attachment points disposed on at least one surface thereof. The implement attachment points are configured to couple and retain at least one agricultural implement to the implement attachment member.

[0040] In some embodiments, the implement attachment member may further comprise a plurality of wheel members coupled to a surface, configured to facilitate mobility during operation, transportation and storage of the modular agricultural toolbar. A person of ordinary skill in the art would appreciate that an attachment point for the plurality of wheels may be one of the plurality of implement attachment points or may be a dedicated wheel attachment point disposed upon a surface of the implement attachment member.

[0041] In one embodiment, the implement attachment member of the modular agricultural toolbar may further comprise interconnected, telescoping segments, configured to allow extension or retraction of a length of the implement attachment member along a central axis of the attachment member.

[0042] In another embodiment, the modular agricultural toolbar may further comprise at least one planter implement extension member coupled to the implement attachment member and configured to further couple agricultural implements requiring further structural support during operation thereof. The planter implement extension member may further comprise a plurality of implement attachment points disposed upon a surface thereof and configured to couple agricultural implements, similar to the plurality of implement attachment points of the implement attachment member. The implement attachment points may be further configured to allow offset coupling of implements between the implement attachment member and the planter implement extension member. For example, where a sowing or planting process is performed, should a distance between implement attachment points be too great for the purposes of a user's needs, one or more planter implement extension members with offset attachment points may be coupled in succession to the implement attachment member, thereby allowing for coupling of implements at a smaller distance between each, effectively narrowing a distance between a resulting row of crops planted.

[0043] A shown in FIGS. 6-7, the modular agricultural toolbar further comprises a rotational gear assembly coupled to the stationary bracket of the core frame, the assembly configured to rotate along a vertical axis and facilitate operational maneuvers such as turning or angling an implement along a geographical bearing. The rotational gear assembly may further comprise a vertical axis configured to rotationally retain the assembly to the core frame of the agricultural toolbar, allowing for rotational movement during use of the toolbar. The vertical axle of the rotational gear assembly is further coupled through a bearing to a motor, the motor configured to rotate the bearing and vertical axle along a vertical axis, thereby moving the rotational gear assembly during use of the agricultural toolbar.

[0044] The rotational gear assembly is further coupled through a horizontal axle to a plurality of continuous track units, as shown in FIGS. 8-10. The plurality of continuous track units is further comprised of an anchoring body; a plurality of internal wheels coupled to the anchoring body; a fender member coupled to the anchoring body, and a tread member coupled to the internal wheels. The internal wheels are configured to moveably retain the tread member and allow continuous movement of the tread member. The tread member may comprise at least one outward surface configured to frictionally couple a surface during operation of the agricultural toolbar. A person of ordinary skill in the art will understand and appreciate that the tread units may be manufactured from any durable yet pliable material. A person of ordinary skill in the art would further appreciate that any number of continuous track units may be attached to the horizontal axle in order to tailor support and weight distribution needs of the user.

[0045] In one embodiment, the rotational gear assembly of the agricultural toolbar further comprises an anchoring plate coupled to and between both the vertical axle and the bearing. The anchoring plate may further be moveably coupled to a first end of a plurality of hydraulic cylinders. A second end of the plurality of hydraulic cylinders is further coupled to the core frame of the agricultural toolbar. The plurality of hydraulic cylinders are configured to extend and retract in response to either an input force or to the movement of the anchoring plate. This configuration allows for the hydraulic cylinders to maintain stability between the rotational gear assembly and the core frame during operation and to absorb or lessen tremor forces generated by operation of the toolbar on uneven, rough, or contoured surfaces while maintaining overall balance of the implement attachment member and any coupled implements through the core frame.

[0046] In some embodiments of the agricultural toolbar, the stationary bracket of the core frame may comprise a plurality of structural units, each coupled to the core frame and spanning the central channel. The plurality of structural units may be configured to further couple the vertical axle or the plurality of hydraulic cylinders of the rotational gear assembly.

[0047] In another embodiment of the agricultural toolbar, as shown in FIG. 11, a supply member may be coupled to the core frame and configured to supply substances to implements attached to the at least one implement attachment member or attached to the at least one planter implement extension member, as shown in FIG. 12. In some embodiments, the stationary bracket of the core frame may extend a length away from the core frame, forming an attachment point for the supply member to be coupled to.

[0048] A person of ordinary skill in the art will understand and appreciate that the supply member may comprise a tank or hopper structure and may be configured to supply multiple substances needed for a given agricultural process. A supplied substance may comprise, but is not limited to, granular solids, liquids, or gaseous mixtures. A person of ordinary skill in the art will understand and appreciate that a liquid supply may include but is not limited to water, pesticide, herbicide, or other chemical mixture. A person of ordinary skill in the art will further appreciate that the granular solids may include but are not limited to seeds, pellets, grains, or other granular chemical required for an agricultural process. In some embodiments of the invention, a dry fertilizer box may be coupled to the agricultural toolbar and configured to function alongside the tank in strip till tillage processes. In some embodiments, the supply tank structure may have a capacity of three-thousand gallons.

[0049] In other embodiments, the plurality of wheels of the implement attachment member may be further configured to support the agricultural toolbar during transportation on paved, graveled, or other roadway surfaces. Further, the plurality of wheels may also comprise a hydraulic cylinder coupled thereto and configured to absorb shock forces from transportation on both roadways and farmlands.

[0050] In another embodiment of the modular agricultural toolbar, as shown in FIG. 13, the abutting member of the core frame may be configured to couple a planter implement extension member, similar in structure and function to the at least one planter implement extension member that may be coupled to the at least one implement attachment member.

[0051] In some embodiments of the invention, both the plurality of hydraulic cylinders and motor of the rotational gear assembly, and the hydraulic piston of the core frame may be configured to interact with a modulator, including but not limited to an onboard computer, a connection module configured to integrate into an already-existing computer control system, or an internal or external global positioning system (GPS) unit or real-time kinematics (RTK) positioning. The modulator is further configured to send commands to the connected hydraulic cylinders, motor, and hydraulic piston, causing an extension or retraction of either component. This configuration allows for a command terminal to be affixed to either the toolbar itself or the hauling means, enabling the user to extend and retract the at least one implement attachment member, raise or lower the rotational gear assembly, and rotate the rotational gear assembly in relation to the core frame. Raising or lowering the rotational gear assembly further allows for adaptive height during operation of the toolbar, enabling a user to fine tune the performed process to conform with the topography of a given farmland. In some embodiments, raising the rotational gear assembly further enables the plurality of continuous track units to disengage a ground surface while the plurality of wheels are still engaged, along for transportation of the agricultural toolbar without utilizing the continuous track units. A person of ordinary skill in the art will understand and appreciate that non-use of the continuous track units during transportation enables generally higher rates of travel during transportation and may preserve a working condition of the plurality of continuous track units for a longer period of time. The rotation of the rotational gear assembly further enables adaptive adjustment of a heading of the toolbar during operation. Extension or retraction of the implement attachment members further enables a user to transition the toolbar between the operational and storage configurations without manual manipulation of the toolbar.

[0052] In some embodiments, the interconnected, telescoping segments of the implement attachment bar may further comprise a mechanical mechanism coupled to the modulator of the agricultural toolbar, configured to allow mechanical extension or retraction of the implement attachment bar along the central axis of the attachment member. Such a configuration further allows adjustment of a field coverage by the implement attachment bar without manual manipulation by the user. In other embodiments, the agricultural toolbar may comprise a weight capacity of forty-five thousand pounds.

[0053] Operation of the modular agricultural toolbar comprises a user first attaching a number of various implements required for a given agricultural process to the implement attachment member. A user may also couple a planter implementation extension member to the implement attachment member, depending on the desired implements that must be attached. Once the implements are attached, the user then couples the toolbar to a hauling means while the toolbar is in the storage configuration. The user then transports the toolbar to a desired location for cultivation or similar processes and either manually or electronically manipulates the hydraulic rod to move the sled bracket and attached pivotal support members such that the implement attachment member will extend from a position parallel to the core frame to a position perpendicular to the core frame. The user then causes the rotational gear assembly to lower until the plurality of continuous track units engages a ground surface. Once engaged, the user may then extend or retract the at least one implement attachment bar to a desired length and begin performance of the desired agricultural process.

[0054] Once finished, the user then returns the implement attachment member to a length suitable for transporting the toolbar, raises the rotational gear assembly until the plurality of continuous track units disengages the ground surface, and retracts the implement attachment member by commanding the hydraulic piston to move the sled bracket and pivotal support members until the implement attachment member is parallel with the core frame. The user then transports the modular agricultural toolbar to a place of storage and may decouple the toolbar from the hauling means for long term storage of the agricultural toolbar.

[0055] Those of ordinary skill in the art will understand and appreciate that the foregoing description of the invention has been made with reference to certain exemplary embodiments of the invention, which describe a modular agricultural toolbar. Those of skill in the art will understand that obvious variations in construction, material, dimensions, or properties may be made without departing from the scope of the invention which is intended to be limited only by the claims appended hereto.
