Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a high-stability fully suspended reversible plow depth-limiting travel wheel. Background Technology

[0002] During the tillage process, the depth limiting wheel of the reversible plow plays a role in limiting and adjusting the tillage depth.

[0016] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown, this embodiment discloses a high-stability fully suspended reversible plow depth-limiting travel wheel, including a depth-limiting wheel assembly fixed to the main beam 1 of the reversible plow. The depth-limiting wheel assembly includes a connecting seat 2, which is fixed to the main beam 1 of the reversible plow. A depth-limiting wheel swing arm bushing 3 is provided on one side of the connecting seat 2. The rear end of the depth-limiting wheel swing arm bushing 3 is rotatably connected to the connecting seat 2, and the front end of the depth-limiting wheel swing arm bushing 3 is connected to an adjusting arm 4. The installation angle of the depth-limiting wheel assembly relative to the main beam 1 of the reversible plow can be finely adjusted through the adjusting arm 4 to adapt to different tillage operation conditions and improve the overall adaptability of the machine. A depth-limiting wheel swing arm shaft 5 is rotatably connected to the depth-limiting wheel swing arm bushing 3. A wear-resistant sleeve is fitted onto the depth-limiting wheel swing arm shaft 5 to reduce wear between the shaft and the bushing 3 during rotation. A friction damping assembly 6 is provided at one end of the depth-limiting wheel swing arm shaft 5 to dampen and stabilize it during rotation. A depth-limiting wheel support arm 7 is provided at the other end of the shaft, and a depth-limiting wheel 8 is mounted on the support arm 7.

[0018] A depth-limiting wheel support plate 9 is fixed to the side of the depth-limiting wheel support arm 7. The depth-limiting wheel support plate 9 has two support grooves 10 on the side facing the depth-limiting wheel support arm bushing 3. Each support groove 10 has a limit support arm 11 in front of it. The limit support arm 11 is rotatably connected to the depth-limiting wheel support arm bushing 3.

[0019] like Figure 4 and 6As shown, the friction damping assembly 6 includes a damping disk 601, which is fixed on the rocker arm shaft 5 of the depth limiting wheel. A first clamping plate 602 and a second clamping plate 603 are respectively provided on both sides of the damping disk 601. Friction plates 604 are fixed on the side of the first clamping plate 602 and the second clamping plate 603 facing the damping disk 601, and the friction plates 604 are in contact with the damping disk 601.

[0020] like Figure 7 As shown, in this embodiment, the end of the depth limiting wheel swing arm shaft 5 that mates with the damping disk 601 is machined with a double-sided flat section; at the same time, a special-shaped hole is provided in the damping disk 601, and the double-sided flat section of the depth limiting wheel swing arm shaft 5 is inserted and mated with the special-shaped hole of the damping disk to form a linkage.

[0021] The first clamping plate 602 is fixed to the rocker arm bushing 3 of the depth limiting wheel by bolts. Multiple screws 605 are arranged in a ring on the first clamping plate 602. The second clamping plate 603 is fitted on the screws 605. A spring 606 and an adjusting nut 607 are provided on the screws 605. The adjusting nut 607 is threaded to the screw 605. The two ends of the spring 606 abut against the adjusting nut 607 and the second clamping plate 603, respectively.

[0022] A friction plate 604 is provided between the damping disc 601 and the clamping disc, and the friction pair is clamped together by a compression spring 606. By rotating the adjusting nut 607 to adjust the preload of the spring 606, the friction force between the damping disc 601 and the friction plate 604 can be changed, forming an adaptively adjustable rotary damping structure.

[0023] like Figure 8 As shown, the adjusting arm 4 includes an adjusting kit 401, with adjusting rods 402 threadedly connected to both ends of the adjusting kit 401. The threads on the two adjusting rods 402 rotate in opposite directions. One adjusting rod 402 is rotatably connected to the depth-limiting wheel swing arm bushing 3, and the other adjusting rod 402 is rotatably connected to the main beam 1 of the reversible plow. Rotating the adjusting kit 401 can change the overall length of the adjusting arm 4, thereby adjusting the installation angle of the depth-limiting wheel assembly relative to the main beam 1 of the reversible plow.

[0024] like Figure 9 and 10 As shown, the limiting support arm 11 includes a support kit 1101, which is rotatably connected to the depth limiting wheel swing arm bushing 3. A push rod 1102 is threaded onto the support kit 1101, and a support horn 1103 is provided at the end of the push rod 1102 away from the support kit 1101. The support horn 1103 abuts against the support groove 10. By rotating the extension and retraction length of the push rod 1102, the height of the depth limiting wheel can be precisely adjusted, thereby controlling the tillage depth of the operation.

[0025] In this embodiment, a frame-shaped handle 1104 is rotatably connected to the top rod 1102, and an anti-rotation boss 1105 is provided on the support kit 1101. The top rod 1102 can be driven to rotate by operating the frame-shaped handle 1104. After the length of the top rod 1102 is adjusted, the frame-shaped handle 1104 is fitted onto the anti-rotation boss 1105. An anti-disengagement pin 1106 is provided on the anti-rotation boss 1105. The anti-disengagement pin 1106 abuts against the frame-shaped handle 1104 to prevent the frame-shaped handle 1104 from disengaging from the anti-rotation boss 1105.

[0026] like Figure 11 As shown, in this embodiment, the depth-limiting wheel swing arm bushing 3 is provided with a limiting boss 12 for limiting the limiting support arm 11. When the reversible plow is flipped, the lower limiting support arm 11 abuts against the limiting boss 12 to prevent it from sagging further. The supporting horn 1103 of the upper limiting support arm 11 abuts against the supporting groove 10. The limiting support arm 11 forms a rigid support, realizing the function of limiting the tillage depth of the implement.

[0027] like Figures 12 to 14 As shown, the depth limiting wheel support arm 7 is L-shaped. The front horizontal part of the depth limiting wheel support arm 7 is connected to the depth limiting wheel swing arm shaft 5 through the adapter seat 13. The adapter seat 13 includes two connecting plates 1301 arranged side by side. The two connecting plates 1301 are connected by multiple spacer connectors 1302. One of the connecting plates 1301 is fixed to the depth limiting wheel swing arm shaft 5. The front horizontal part of the depth limiting wheel support arm 7 is located between the two connecting plates 1301, and the front horizontal part of the depth limiting wheel support arm 7 is rotatably connected to the two connecting plates 1301 through the rotating shaft 1303.

[0028] Two sets of limiting holes 1304 are provided on the connecting plate 1301 with the rotating shaft 1303 as the center. One set of limiting holes 1304 corresponds to the farmland depth limiting operation mode, and the other set of limiting holes 1304 corresponds to the ground wheel road transport walking mode. The front horizontal part of the depth limiting wheel support arm 7 is provided with a positioning hole 1305 with the rotating shaft 1303 as the center. The positioning hole 1305 is fixed by inserting a locking pin 1306 after corresponding with one of the limiting holes 1304.

[0029] The spacer connector 1302 includes a bolt assembly 1302-1 and a spacer sleeve 1302-2. The bolt assembly 1302-1 connects and fixes two connecting plates 1301, and the spacer sleeve 1302-2 is fitted onto the bolt assembly 1302-1 and is located between the two connecting plates 1301. The bolt assembly 1302-1 mainly includes a bolt and a nut.

[0030] The operation process of this invention is as follows: During operation, the rotating adjustment kit 401 can change the overall length of the adjustment arm 4, thereby adjusting the installation angle of the depth limiting wheel assembly relative to the main beam 1 of the overturning plow.

[0031] In the farmland depth restriction operation mode (such as) Figure 11 As shown, after the reversible plow flips, the lower limiting support arm 11 abuts against the limiting boss 12 to prevent further sagging, while the supporting horn 1103 of the upper limiting support arm 11 abuts against the supporting groove 10. The limiting support arm 11 forms a rigid support, realizing the tillage depth limiting function of the implement. During the flipping process, the depth limiting wheel swing arm shaft 5 rotates around the depth limiting wheel swing arm bushing 3. The friction damping component 6 generates friction damping to slow down the rotation of the depth limiting wheel swing arm shaft 5, reducing the speed of the depth limiting wheel 8 during its descent and decreasing the impact force on the limiting support arm 11. In addition, when the depth limiting wheel 8 encounters undulating ground during operation, the friction damping component 6 reduces the vibration of the depth limiting wheel 8, similarly reducing the impact force on the limiting support arm 11.

[0032] Additionally, in the case of depth-limited vessel transportation (such as...) Figure 14 As shown, the depth-limiting wheel 8 rolls in contact with the road surface. When the depth-limiting wheel 8 rotates, the depth-limiting wheel swing arm shaft 5 rotates around the depth-limiting wheel swing arm bushing 3. The depth-limiting wheel angle has no limiting device, allowing for 360° follow-through steering. Due to the tractor's rear suspension height and the structure of the traveling wheels, the entire machine will sway, undulate, and shake when the depth-limiting wheel swings. At this time, the friction damping component 6 can reduce the swing frequency of the depth-limiting wheel, reducing overall machine shaking and bumping, thus reducing impact damage to the unit and extending its service life.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
