Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery components, in particular to a new type of depth-limiting walking mechanism for a reversible plow. Background Art

[0002] The reversible plow is an agricultural machine that can realize two-way soil turning. Two sets of plow bodies with different directions are installed on the upper and lower parts of the plow frame. They are used separately in the round trip through the reversing mechanism to achieve the purpose of turning the soil to one side. The reversible plow is usually used with a depth-limiting wheel assembly. The depth-limiting wheel assembly is connected to one side of the plow body to control the plowing depth of the plow body. By adjusting the height of the wheel body in the depth-limiting wheel assembly, the depth of the plow body in the soil can be controlled to meet different agricultural needs.

[0003] The existing depth limiting wheel assembly is mainly composed of a mounting frame, a connecting arm, a wheel body and a limiting piece. The mounting frame is fixedly connected to the plow frame, the connecting arm is rotatably installed on the mounting frame, the wheel body is rotatably connected to the end of the connecting arm, and the limiting piece is mainly composed of a right-angle block and two screws. The right-angle block is fixedly connected to the mounting frame, and the two screws are respectively tightened in two plate walls of the right-angle block, one of the screws will correspond to the connecting arm, and rotating the screw outward or inward can limit the rotation angle of the connecting arm. When the connecting arm rotates counterclockwise away from the ground, it will be blocked by the end of the screw, thereby limiting the height of the wheel body when traveling. When the plow body is flipped over, the other screw will correspond to the connecting arm, and similarly rotating the screw outward or inward can limit the clockwise rotation angle of the connecting arm away from the ground.

[0004] However, both screws need to be rotated separately by the staff, and the distance of the two screws rotating outward or inward is not easy to control. At the same time, when the reversible plow is driven by the tractor to plow the ground, the reversible plow will vibrate strongly, which will drive the depth limit wheel assembly to vibrate strongly. At this time, the screws are easily loosened and deviated from the original position due to long-term vibration, thus affecting the accuracy of the plowing depth. For this reason, we propose a new reversible plow depth limit walking mechanism. Summary of the invention

[0031] See also Figure 3 , Figure 4 , Figure 5 and Figure 7 In the figure, the unlocking mechanism includes an L-shaped block 35, which is fixedly connected to the front end of the V-shaped block 11 near the stud 14, and the inner wall of the L-shaped block 35 is slidably interspersed with a pillar 34, and the rear end of the pillar 34 is fixedly connected to a splicing plate 23, and a spring three 33 is fixedly connected between the splicing plate 23 and the L-shaped block 35.

[0032] See also Figure 3 , Figure 4 and Figure 7 In the figure, the pushing member includes two arc plates 28, which are symmetrically slidably inserted into the inner wall of the rotating block 10, and the ends of the two arc plates 28 corresponding to the studs 14 are fixedly connected with a pushing ring 39, and the ends of the two arc plates 28 away from the studs 14 are fixedly connected with a disc 9, and the end of the pushing ring 39 away from the arc plates 28 is in contact with the inclined surface of the triangular block 38.

[0033] In this embodiment, when the motor 4 is started, the connecting arm 3 and the wheel body 1 can be driven to rotate, thereby adjusting the height of the wheel body 1. In this depth-limiting wheel assembly, two baffles 12 are used to limit the rotation angle of the connecting arm 3. At this time, the two baffles 12 overlap on the V-shaped block 11, and at this time, the distance between the connecting arm 3 and the corresponding baffle 12 is the maximum angle that the connecting arm 3 can rotate. When it is necessary to adjust the baffle 12 outward to reduce the distance between the connecting arm 3, the rotating block 10 is rotated to drive the stud 14 to rotate, the stud 14 can drive the screw sleeve 24 to move in the direction of the V-shaped block 11, the screw sleeve 24 can drive the two connecting rods 13 to rotate synchronously, the two connecting rods 13 can drive the two square plates 21 to move along the two inclined directions of the V-shaped block 11 respectively, and the two square plates 21 can drive the baffles 12 connected to each other to continuously and synchronously extend out of the V-shaped block 11, then the distance between the baffle 12 located below and the connecting arm 3 will be reduced, thereby reducing the rotation angle of the connecting arm 3, thereby limiting the height of the wheel body 1 and limiting the depth of the plow body in the soil.

[0034] When the screw sleeve 24 moves in the direction of the V-shaped block 11, it can drive the two U-shaped blocks 36, the two cylinders 25, the two springs 26, the splicing block 22, the connecting block 27 and the triangular block 37 to move together. The inclined surface of the triangular block 37 will squeeze the inclined surface of one of the triangular grooves 32 and slide out of the triangular groove 32. The triangular block 37 will drive the connecting block 27 to move away from the fixed plate 31. The connecting block 27 will drive the two cylinders 25 to slide in the inner walls of the two U-shaped blocks 36 respectively. The two cylinders 25 can drive the splicing block 22 to move together. The connecting block 27 will also squeeze the spring 26 connected between the two U-shaped blocks 36 until the triangular block 37 corresponds to the next triangular groove 32. Under the action of the spring 26, the triangular block 37 will automatically be inserted into the triangular groove 32, and so on. Figure 6 It can be seen that a plane of the triangular block 2 37 is in contact with a plane of the triangular groove 32. When the stud 14 stops rotating, the triangular block 2 37 will not move back, and the screw sleeve 24 and the two baffles 12 will not move back. When the wheel body 1 falls to the ground and the connecting arm 3 rotates to fit with the corresponding baffle 12, the baffle 12 will not be shifted in position due to the vibration generated by the flip plow when it is driven by the tractor to plow the ground. Moreover, since the two baffles 12 can be adjusted synchronously, the accuracy of the plowing depth can be improved.

[0035] It should be noted that when it is necessary to turn back to the position of the screw sleeve 24, hold the rotating block 10 and push the disc 9 forward with the palm of the hand. The disc 9 can drive the two arc-shaped plates 28 to slide in the inner wall of the rotating block 10, and the two arc-shaped plates 28 can drive the pushing ring 39 to squeeze the inclined surface of the triangular block three 38, then the triangular block three 38 will move away from the screw sleeve 24, and the triangular block three 38 will drive the splicing plate 23 to move together, the splicing plate 23 will drive the pillar 34 to slide outward in the inner wall of the L-shaped block 35, and the splicing plate 23 will also squeeze the spring three 33 connected to the L-shaped block 35, and the splicing plate 23 will also push the splicing block 22 to move together, then the splicing block 22 can drive the triangular block two 37 to leave the corresponding triangular groove 32. At this time, as the rotating block 10 drives the stud 14 to rotate, the screw sleeve 24 can move to its original position without hindrance, then the two baffles 12 can move to their original positions, and the operation of retracting the two baffles 12 on the V-shaped block 11 is also convenient. Finally, under the action of the spring three 33 , the splicing plate 23 , the support column 34 , the triangular block three 38 and the splicing block 22 will return to their original positions, and the triangular block three 38 will continue to be inserted into the corresponding triangular groove 32 .

[0036] Embodiment 2

[0037] See also Figure 1 and Figure 2The present embodiment further explains the first embodiment. The locking mechanism in the figure includes an L-shaped block 2, two square blocks 18 and two triangular blocks 20. The two square blocks 18 are elastically connected to the upper and lower edges of the front end of the V-shaped block 11 through elastic components, and the lower ends of the two square blocks 18 are fixedly connected to an L-shaped plate 6. The front ends of the two L-shaped plates 6 are fixedly connected to plug blocks 5 away from the square blocks 18. The L-shaped block 2 is fixedly connected to the front end of the connecting arm 3 corresponding to the L-shaped plate 6 located below, and the outer wall of the L-shaped block 2 is provided with a slot 19 corresponding to the plug block 5 located below, and the plug block 5 located below is located between the L-shaped plate 6 and the L-shaped block 2.

[0038] See also Figure 2 In the figure, the elastic mechanism includes a connecting column 15, which is fixedly connected to the front end of the V-shaped block 11 corresponding to the block 18, and the end of the connecting column 15 away from the V-shaped block 11 is fixedly connected to a connecting disk 16, and the connecting column 15 movably passes through the block 18, and the outer wall sliding sleeve of the connecting column 15 is provided with a spring 17, and the spring 17 is fixedly connected between the connecting disk 16 and the block 18.

[0039] When the two baffles 12 extend out of the V-shaped block 11 and move to fit with the corresponding L-shaped plate 6, the baffle 12 extends out of the V-shaped block 11 to the maximum distance. At this time, the baffle 12 is continued to be operated to drive the triangular block 20 to move in the direction of the L-shaped plate 6. The inclined surface of the triangular block 20 is squeezed with the outer wall edge of the L-shaped plate 6. The L-shaped plate 6 will move away from the V-shaped block 11, and the L-shaped plate 6 will drive the insert block 5 to be inserted into the slot 19 on the L-shaped block 2. The L-shaped block 2 is fixedly connected to the connecting arm 3, and the angle of the connecting arm 3 at this time can make the bottom of the wheel body 1 flush with the bottom of the wheel of the tractor. At this time, the wheel body 1 is locked by the insert block 5. When the wheel body 1 is not working in the field, it can be used as a support wheel for supporting the flip plow. It can support the flip plow on a normal road surface to achieve dual use.
