Description

Technical Field

[0001] This invention relates to the field of reversible plow technology, specifically to a reversible plow depth-limiting wheel. Background Technology

[0002] When a reversible plow is in operation, the ground wheel needs to be kept facing backward. However, as the plow rotates, the direction of the ground wheel is prone to swaying back and forth, making it difficult to control. This forces the operator to slowly rotate the plow to achieve the correct backward orientation. A slight lapse in attention during operation can cause the ground wheel to face forward, making tilling impossible. The plow must then be raised and slowly lowered again to achieve the correct backward orientation, which is time-consuming, labor-intensive, and significantly reduces work efficiency.

[0003] Therefore, the technical problems reflected above are problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a depth-limiting ground wheel for a reversible plow, in order to solve the problem that the ground wheel cannot guarantee the orientation when the reversible plow is rotating.

[0005] To achieve the above objectives, the following technical solution is adopted: a reversible plow depth-limiting ground wheel, including a ground wheel assembly and a depth-limiting assembly, wherein the ground wheel assembly and the depth-limiting assembly are connected to the reversible plow auxiliary beam tube through a fixed connecting plate;

[0006] A positioning square tube is provided between the ground wheel assembly and the depth limiting assembly. The positioning square tube is fixedly connected to one side of the fixed connecting plate. The ground wheel assembly and the depth limiting assembly are respectively located at both ends of the positioning square tube. The ground wheel assembly includes a bearing sleeve, a rotating support shaft, a positioning plate, a ground wheel tube, and a rubber wheel. The bearing sleeve is fixedly connected to the positioning square tube. The rotating support shaft is located inside the bearing sleeve to form a rotating mechanism. The positioning plate is fixedly connected to the middle of the rotating support shaft. One end of the ground wheel tube is fixedly connected to the top of the rotating support shaft, and the other end of the ground wheel tube is rotatably connected to the rubber wheel.

[0007] Two positioning pins are symmetrically arranged on the side of the positioning plate away from the ground wheel tube. A fixing plate is provided on the positioning square tube. The positioning pins and the fixing plate form an angle limiting mechanism as the positioning plate rotates.

[0008] As an improvement, the depth limiting component includes a limiting connecting plate, a limiting block, and a rotating pin. The limiting connecting plate is located on the side of the positioning square tube away from the bearing sleeve. Fixed rods are symmetrically arranged on the limiting connecting plate. The limiting block is rotatably connected to the limiting connecting plate through the rotating pin and forms an angle limiting mechanism with the fixed rods. A positioning seat welded part is provided in the middle of the ground wheel tube. Adjusting bolts are symmetrically arranged at both ends of the positioning seat welded part. The adjusting bolts cooperate with the limiting block to form a limiting mechanism.

[0009] The advantages of this invention compared with the prior art are as follows: By adding a limiting mechanism, this invention ensures that the direction of the ground wheel is always backward when the reversible plow rotates, which can quickly reverse and fall, improving work efficiency by up to 30%-50%. It is convenient and fast, and the structure is simple, practical and durable with a low failure rate, solving the problem of the reversible plow's ground wheel not being able to be positioned. This invention also has a depth limiting component, which can control the depth at which the ground wheel falls into the tilled land. Attached Figure Description

[0016] Combined with appendix Figure 1-2 The reversible plow depth limiting wheel includes a wheel assembly and a depth limiting assembly, wherein the wheel assembly and the depth limiting assembly are connected to the reversible plow auxiliary beam tube 2 via a fixed connecting plate 1;

[0017] A positioning square tube 3 is provided between the ground wheel assembly and the depth limiting assembly. The positioning square tube 3 is fixedly connected to one side of the fixed connecting plate 1. The ground wheel assembly and the depth limiting assembly are respectively located at both ends of the positioning square tube 3. The ground wheel assembly includes a bearing sleeve 4, a rotating support shaft 5, a positioning plate 6, a ground wheel tube 7, and a rubber wheel 8. The bearing sleeve 4 is fixedly connected to the positioning square tube 3. The rotating support shaft 5 is located inside the bearing sleeve 4 to form a rotating mechanism. The positioning plate 6 is fixedly connected to the middle of the rotating support shaft 5. One end of the ground wheel tube 7 is fixedly connected to the top of the rotating support shaft 5, and the other end of the ground wheel tube 7 is rotatably connected to the rubber wheel 8.

[0018] Two positioning pins 9 are symmetrically arranged on the side of the positioning plate 6 away from the ground wheel tube 7. A fixing plate 10 is provided on the positioning square tube 3. The positioning pins 9 and the fixing plate 10 form an angle limiting mechanism as the positioning plate 6 rotates.

[0019] The depth limiting component includes a limiting connecting plate 11, a limiting block 12, and a rotating pin 13. The limiting connecting plate 11 is located on the side of the positioning square tube 3 away from the bearing sleeve 4. A fixing rod 14 is symmetrically arranged on the limiting connecting plate 11. The limiting block 12 is rotatably connected to the limiting connecting plate 11 through the rotating pin 13 and forms an angle limiting mechanism with the fixing rod 14. A positioning seat welding part 15 is provided in the middle of the ground wheel tube 7. Adjusting bolts 16 are symmetrically arranged at both ends of the positioning seat welding part 15. The adjusting bolts 16 cooperate with the limiting block 12 to form a limiting mechanism.

[0020] In practical implementation of this invention, before the plow frame begins to tilt under the hydraulic control of the tractor, the positioning pin 9 and the positioning plate 6 are welded to the rotating support shaft 5 and contact the fixing plate 10, creating an inclined angle for the ground wheel. When not in operation, the positioning pin 9 and the fixing plate 10 fall vertically under their own weight, then contact each other, providing a limiting function. If the plow frame begins to fall and operate, after the rubber wheel 8 contacts the ground, the rotating support shaft 5 rotates within the bearing sleeve 4. Because the fixing plate 10 prevents the positioning pin 9 from rotating further, the rubber wheel 8 naturally rotates to the left and will never rotate to the right.

[0021] During the flipping process of the tractor-driven plow frame, the limiting block 12 rotates from approximately 42° to 0°. At this point, an eccentric function is generated relative to the rotation center after rotation. At this point, the distance between the limiting block 12 and the rotation center of the ground wheel assembly is the longest, which ensures that the ground wheel assembly can pass smoothly through the limiting block 12 during the flipping process.

[0022] The plow frame continues to descend under the hydraulic control of the tractor. Once it reaches the required depth for tilling, adjusting bolt 16 contacts the limiting block 12. After contact, the limiting block 12 contacts the fixing rod 14, restricting its rotation and thus pressing against the positioning seat welded part 15, preventing further rotation of the ground wheel assembly. The depth is then controlled; if the depth is not satisfactory, adjusting bolt 16 (serial number 10) can be used for adjustment.

[0023] When the reversible plow is in operation, the adjusting bolt 16 contacts the limiting block 12. After the limiting block 12 is subjected to force, it rotates through the center. The other end of the limiting block 12 contacts the fixing rod 14 and is then positioned, thus achieving depth positioning. The depth can be adjusted by adjusting the adjusting bolt 16.

[0024] After the reversible plow completes its unidirectional operation, the tractor drives the plow frame to flip. After flipping to the reverse side, the depth limiting function and its various steps in the reverse direction are the same as before the flip. At this time, the reversible plow frame begins to flip under the control of the tractor. When it flips to approximately 120 degrees, the limit block 12 is in a horizontal state, the adjusting bolt 16 is not in contact with the limit block 12, and the ground wheel assembly passes through completely. After passing through, the entire limit wheel mechanism is in the same state as before the flip.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
