Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, specifically to a novel buffer-type depth-limiting wheel. Background Technology

[0002] A plow is a tillage tool whose main function is to turn and break up soil. The depth control wheel on the plow controls the tillage depth. Raising or lowering the depth control wheel changes the vertical distance from the lower edge of the wheel to the plow's support surface, thus altering the tillage depth. Existing depth control wheels can rotate, but when they rotate with the plow, they rely on their own weight to rotate backward, impacting the connecting components and easily causing damage. Furthermore, the tillage depth adjustment of existing depth control wheels mostly relies on pins for fixed adjustment, which cannot be adjusted in real time, thus having certain limitations.

[0003] A patent publication number (CN215601806U) was found, entitled "A Depth-Limiting Wheel with Buffer Structure for a Reversible Plow," which specifically discloses a depth-limiting wheel with a buffer structure for a reversible plow. The wheel includes a depth-limiting seat, a depth-limiting shaft, a traveling mechanism, a rotation control mechanism, a tillage depth control mechanism, and a buffer mechanism. The depth-limiting shaft is disposed within the depth-limiting seat, and the traveling mechanism, rotation control mechanism, tillage depth control mechanism, and buffer mechanism are sequentially connected to the depth-limiting shaft. The buffer mechanism includes a damper; one end of the damper is connected to the depth-limiting shaft via a damper fixing pin, and the other end is connected to the traveling mechanism via a damper lower fixing pin. Further, the tillage depth control mechanism includes an adjusting rod; both ends of the depth-limiting seat are connected to an adjusting rod fixing seat via adjusting rod fixing bolts, and the adjusting rod is disposed on the adjusting rod fixing seat. The depth-limiting shaft has a groove that mates with the adjusting rod. Further, the traveling mechanism includes a depth-limiting wheel mounting frame, which is connected to the end of the depth-limiting shaft via the rotation control mechanism, and a depth-limiting wheel is connected to the mounting frame. The damper's lower fixing pin is connected to one side of the depth-limiting wheel mounting bracket. Further, the rotation control mechanism includes a depth-limiting conversion pin and a depth-limiting shaft fixing bolt. The depth-limiting wheel mounting bracket is connected to the depth-limiting rotating shaft via the depth-limiting shaft fixing bolt. The depth-limiting wheel mounting bracket has two through holes that mate with the depth-limiting conversion pin. The two through holes are distributed in a right-angled triangle with the depth-limiting shaft fixing bolt. The depth-limiting rotating shaft has through holes for the depth-limiting shaft conversion pin that mate with the through holes.

[0004] Analysis of the above-mentioned publicly available materials shows that the damper is installed. During the reversing process of the hydraulic reversible plow, the damper generates a damping effect, which reduces the speed of the depth limiting wheel during the fall and reduces the impact force. However, the adjustment effect on the depth limiting wheel is not good, and the depth limiting wheel cannot be oscillated and positioned during the reversing process of the plow.
