Description

Technical Field

[0001] This utility model relates to the field of disc plow technology, and specifically to a bidirectional disc plow linkage steering adjustment device. Background Technology

[0002] As an important implement in modern agriculture, the disc plow's steering adjustment performance directly affects operational efficiency and soil treatment quality. Traditional two-way disc plows mostly use gear transmission or hydraulic drive for steering adjustment, which suffers from problems such as complex structure, slow operation response, and high maintenance costs. For example, some existing devices directly connect the plow frame and steering mechanism with rigid linkages, resulting in limited steering angle, poor synchronization, and deviation of the tillage trajectory, making them difficult to adapt to the operational needs of complex terrain.

[0003] Although existing bidirectional disc plows use hydraulic drive or mechanical linkage structures to achieve steering adjustment, they still have the following technical shortcomings:

[0004] 1. Existing hydraulic steering systems require complex hydraulic components such as oil pumps and pipelines, which are prone to problems such as oil leakage and blockage under harsh field conditions, making it difficult to adapt to the adjustment needs of different soil conditions;

[0005] 2. Conventional mechanical linkage structures generally suffer from low degree of adjustment freedom. The steering rod and the adjusting rod adopt a single hinge method, which limits the adjustment range of the disc plow angle and makes it impossible to achieve rapid switching during bidirectional symmetrical tillage.

[0006] 3. Existing adjustment devices generally lack a synchronous temperature structure, and there is no effective support between the steering shaft and the connecting rod. This can easily cause mechanical vibration during high-speed tillage, resulting in uneven depth of the plow body into the soil and affecting the quality of tillage. Utility Model Content

[0007] The purpose of this invention is to provide a bidirectional disc plow linkage steering adjustment device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional disc plow linkage steering adjustment device, comprising a frame, a steering assembly, an adjustment assembly, a steering rod, an adjustment rod, and a disc plow, characterized in that: supports are fixedly provided on both sides of the frame, a support plate is fixedly connected to the upper end of the supports, both ends of the support plate are hinged to one end of the adjustment rod through a first pin, the other end of the adjustment rod is fixedly connected to a side plate, the side plate is fixedly disposed above the steering rod, a steering shaft is fixedly connected to one end of the steering rod, one end of the steering shaft is connected to the steering assembly, and the steering assembly is fixedly disposed in front of the frame;

[0009] One end of the adjustment component is fixedly installed at the bottom side of the bracket, and the other end is fixedly connected to one side of the steering rod. The other end of the steering rod is connected to the upper half of the fixed plate, and the lower half of the fixed plate is connected to a connecting rod. Multiple disc plows are evenly connected to the connecting rod.

[0010] Preferably, the steering assembly includes a steering gear, a main cylinder, and a second pin. The steering gear is fixedly installed at the front of the frame and its two ends are fixedly connected to the main cylinder. A steering shaft is sleeved inside the main cylinder, and the upper and lower ends of the steering shaft are connected to the main cylinder through the second pin.

[0011] Preferably, the steering shaft has a hollow structure inside, and its outer wall is fitted with the inner wall of the main cylinder, with the upper and lower ends forming a hinged motion through the second pin.

[0012] Preferably, the main cylinder and the end face of the steering shaft are provided with a semi-circular groove to facilitate the steering shaft to be adjusted for steering within the main cylinder.

[0013] Preferably, the adjustment assembly includes a first universal joint, a second universal joint, an adjustment cylinder, a pneumatic shaft, and an inflation tube. The first universal joint is fixed to the bottom side of the bracket and connected to the adjustment cylinder. The pneumatic shaft inside the adjustment cylinder is connected to the second universal joint. The second universal joint is fixed to one side of the steering rod. An inflation tube is provided on the surface of the adjustment cylinder to facilitate the extension and retraction of the pneumatic shaft by air pressure.

[0014] Preferably, the main cylinders connected to both ends of the steering gear are inclined to form a figure-eight structure and are supported and fixed by support columns.

[0015] Preferably, a fixing rod is fixedly connected below the steering shaft, and the other end of the fixing rod is fixedly connected to the connecting rod to fix the synchronization of the supporting connecting rod and the steering rod.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model adopts a linkage design between the first universal joint, the second universal joint and the adjusting cylinder in the adjusting assembly, and replaces the traditional hydraulic system with air pressure drive, effectively avoiding common field faults such as hydraulic oil leakage and pipeline blockage; the air shaft extension and retraction combined with the air pressure control of the air inflator not only simplifies the transmission structure, but also improves the speed of rapid adjustment under harsh working conditions and reduces maintenance costs.

[0018] 2. The steering assembly adopts a combination structure of a figure-eight inclined main cylinder and a hollow steering shaft. Combined with the semi-circular groove design on the end face of the main cylinder and the steering shaft, the steering shaft can swing bidirectionally within the main cylinder. With the multi-point hinge structure of the adjusting rod and the support plate, the limitation of the single degree of freedom of the mechanical linkage is solved, which increases the adjustment range of the disc plow's tillage angle, meets the need for quick switching during bidirectional symmetrical tillage, and improves work efficiency.

[0019] 3. The connecting rod is rigidly connected to the steering rod and steering shaft through the fixed plate and fixed rod, realizing synchronous transmission between the connecting rod and the steering rod. This design allows the disc plow to control the consistency of the soil entry angle and depth when turning through the steering shaft, effectively suppressing the deviation caused by vibration due to ground undulation during high-speed operation, and improving the tillage quality problem caused by poor synchronization.

[0020] 4. The key transmission adjustment component, the adjustment cylinder, is externally mounted, which facilitates quick field maintenance. Moreover, pneumatic control has a faster response time than hydraulic control, thus improving work efficiency. Attached Figure Description

Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0026] This utility model is as follows Figure 1-3A bidirectional disc plow linkage steering adjustment device is shown: including a frame 1, a steering assembly, an adjustment assembly, a steering rod 9, an adjustment rod 7 and a disc plow 14. The frame (1) has symmetrically distributed brackets 4 welded and fixed on both sides. The upper end of the brackets 4 is fixedly connected to a horizontally arranged support plate 5 by bolts. The two ends of the support plate 5 are hinged to one end of the adjustment rod 7 by the first pin 6. The other end of the adjustment rod 7 is fixed to the side plate 8 by bolts. The side plate 8 is fixed parallel to the steering rod 9 above. One end of the steering rod 9 is fixedly connected to the steering shaft 10 by bolts. The other end of the steering shaft 10 is sleeved with the main cylinder 22 of the steering assembly fixed to the front end of the frame 1.

[0027] The adjustment component is fixed to the bottom side of the bracket 4 via the first universal joint 31, and the other end is connected to the side of the steering rod 9 via the second universal joint 32. The end of the steering rod 9 is fixed to the upper half of the fixing plate 11 by bolts, and the lower half of the fixing plate 11 is fixedly connected to the connecting rod 13 by bolts. Five sets of disc plows 14 are installed at equal intervals on the connecting rod 13. When tilling, the adjustment component drives the steering rod 9 to swing, which drives the connecting rod 13 to deflect synchronously, so as to realize the bidirectional tillage angle adjustment of the disc plow 14.

[0028] The steering assembly specifically includes a steering gear 21, a main cylinder 22, and a second pin 23. The steering gear 21 is a horizontal cylindrical structure, which is fixed to the center of the front end of the frame 1 by bolts. The main cylinder 22 is symmetrically welded on the left and right sides. The steering shaft 10 is nested inside the main cylinder 22. The upper and lower ends of the steering shaft 10 are hinged to the main cylinder 22 through the second pin 23. The steering shaft 10 can be driven and controlled by the adjusting cylinder 33 of the adjusting assembly, so that the steering shaft 10 swings around the second pin 23 on the inner axis of the main cylinder 22, thereby driving the steering rod 9 to move synchronously.

[0029] The steering shaft 10 is a hollow structure made of steel pipe. Its outer diameter is clearance-fitted with the inner diameter of the main cylinder 22. The upper and lower ends of the steering shaft 10 are provided with through holes, which are hinged to the second pin 23 at the end of the main cylinder 22. The contact end face of the main cylinder 22 and the steering shaft 10 is provided with a semi-arc groove 101. When the steering shaft 10 swings, the semi-arc groove 101 guides the steering shaft 10 to move along a predetermined trajectory to complete the steering.

[0030] The adjustment assembly consists of a first universal joint 31, a second universal joint 32, an adjustment cylinder 33, and a pneumatic shaft 34. The adjustment cylinder 33 is hinged to the bottom of the bracket 4 through the first universal joint 31, and the end of the pneumatic shaft 34 is connected to the side of the steering rod 9 through the second universal joint 32. The surface of the adjustment cylinder 33 is provided with an air inlet pipe 35, which is connected to an external air pump to achieve rapid response.

[0031] The two main cylinders 22 are inclined on both sides with the steering gear 21 as the center, forming a figure-eight structure. The support column 24 is welded in the middle of the main cylinder 22 to form a triangular support structure. This structure improves the lateral stiffness of the main cylinder 22. When the steering shaft 10 turns, the main cylinder 22 can be stably fixed. A fixing rod is welded to the bottom of the steering shaft 10. The end of the fixing rod 12 is locked to the end of the connecting rod 13 by a clamp. When the steering shaft 10 deflects, the fixing rod 12 transmits the deflection force to the connecting rod 13, so that the connecting rod 13 can quickly complete the angle switching.

[0032] Working principle: During operation, the tractor pulls the frame 1 forward. The operator controls the extension and retraction of the pneumatic control cylinder 33. The steering shaft 10 swings around the second pin 23 on the main cylinder 21. The deflection motion of the steering shaft 10 is transmitted to the fixed plate 11 through the steering rod 9, causing the connecting rod 13 to drive the disc plow 14 to change the soil entry angle synchronously. The adjustment cylinder 33 finely adjusts the deflection amplitude of the steering rod 9 by extending and retracting the air shaft 34 according to the preset tillage mode. When switching the tillage direction, the air shaft 34 quickly extends and retracts to complete the direction switch. The fixed rod 12 and the fixed plate 11 are rigidly connected to the connecting rod to ensure that multiple disc plows move synchronously, suppress vibration and deviation, and achieve efficient and stable bidirectional tillage.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
