Description
Technical Field
[0001] This invention relates to the field of agricultural machinery technology, and in particular to a wheel rut covering mechanism that can be adjusted in multiple dimensions. Background Technology
[0002] To enable agricultural machinery to move in the field, tractors, power chassis, and other power traction devices are required. Due to their heavy weight, these devices easily create ruts in paddy fields or soft soil, affecting subsequent planting and other operations. Therefore, it is necessary to cover the ruts in real time. In the prior art, the applicant's earlier application CN111567160A discloses a structure based on two augers rotating in opposite directions to cover the ruts with soil. In practical use, this structure not only occupies a large space but also has poor adjustability, making it difficult to meet the rut covering needs of different traction machinery. Other prior art, patent CN201303493Y, discloses a soil covering disc machine. Its soil covering disc is connected to the frame through multiple adjusting pipes. The soil covering disc, adjusting pipes, and frame are connected by pipe clamps, forming a continuous cantilever structure. This structure has poor stability, is easily deformed by impact, and the posture of the soil covering disc is prone to change. Furthermore, it is mainly used in dry land and has poor adaptability to rheological soils in paddy fields. The soil covering machine in patent CN219660319U includes two mud-turning plates with variable opening and closing angles. The unfolding angle of the mud-turning plates can be adjusted by a side-expansion adjustment device. The side-expansion adjustment device includes an adjustment connecting plate with an oblong hole. The adjustment connecting plates are fixed together by bolts and nuts. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides a wheel track covering mechanism that can adjust the pose conditions of the covering device in multiple dimensions as needed.
[0004] Technical solution: To achieve the above objectives, the present invention provides a multi-dimensional adjustable wheel rut covering mechanism, which includes a fixed base and two covering plates; each of the covering plates is connected to a first adjusting plate with a first arc hole, and the opening angle between the two covering plates can be adjusted by the first adjusting plate; the two first adjusting plates can be fixed by a first screw passing through the first arc hole on both, so as to fix the relative opening of the two covering plates.
[0005] It also includes a movable seat and a transition plate; the movable seat is connected to the fixed seat via a height adjustment mechanism;
[0006] The two transition plates are rotatably mounted on the movable seats; each movable seat is equipped with a soil covering plate, and a second adjusting plate is fixed on the soil covering plate to adjust the angle of the soil covering plate relative to the transition plate; the relative axis of rotation between the soil covering plate and the transition plate is horizontal, so that the inclination angle of the soil covering plate can be adjusted.
[0007] The first adjusting plate is fixedly installed relative to the transition plate. The opening and closing angle between the two transition plates is directly adjusted by the first adjusting plate to indirectly adjust the angle between the two soil covering plates.
[0008] In the above structure, the height of the covering plate is indirectly adjusted by the height adjustment mechanism to adjust the amount of soil covering; the opening and closing angle of the covering plate is indirectly adjusted by the first adjustment plate to adjust the soil gathering range; and the inclination angle of the covering plate is adjusted by the second adjustment plate to adjust the soil compaction area of the covering plate and adjust the compaction after covering.
[0009] Furthermore, the height adjustment mechanism includes two parallel connecting rods, with each connecting rod hinged at both ends to the fixed seat and the movable seat respectively; the two connecting rods, the fixed seat, and the movable seat together form a parallelogram linkage structure.
[0010] The height adjustment mechanism also includes a telescopic adjustment unit connecting the fixed seat and the movable seat, wherein the telescopic adjustment unit's telescopic direction is not parallel to the connecting rod.
[0011] Furthermore, the telescopic adjustment unit includes a rod, a rotating seat, and an adjusting rod. Of the rod and the rotating seat, one is rotatably connected to the movable seat, and the other is rotatably connected to the fixed seat. In this design, one end of the rod is connected to the movable seat, and the rotating seat is connected to the fixed seat. The adjusting rod and the rod are engaged by a screw pair, and the adjusting rod can rotate relative to the rotating seat. With this structure, rotating the adjusting rod allows relative movement between the adjusting rod and the rod, changing the relative position of the fixed seat and the movable seat. To improve structural compactness, the rod and one of the connecting rods are coaxially hinged to the movable seat.
[0012] Furthermore, a rotary handle is fixed on the adjusting rod, with a flower-shaped part at one end and an annular groove at the other end; the rotating seat has an open groove, the edge of which is embedded in the annular groove; thus, axial positioning of the rotary handle can be achieved, and the installation of the rotary handle is convenient.
[0013] Furthermore, the movable seat has a first U-shaped portion for each of the transition plates, and also includes a second U-shaped portion for the connecting rod portion; the first U-shaped portion is vertically fixed to the back side of the bottom plate of the second U-shaped portion; the two first U-shaped portions corresponding to the two transition plates are arranged back to back, and the three U-shaped portions are welded and fixed together, so that the entire movable seat has high strength; a first U-shaped bracket rotatably connected to the first U-shaped portion is fixed on the transition plate.
[0014] Furthermore, a second U-shaped bracket and a third U-shaped bracket are respectively fixed to the transition plate and the soil cover plate, and the second U-shaped bracket and the third U-shaped bracket are rotatably connected by a rotating shaft.
[0015] Furthermore, an L-shaped fastener with a round hole is fixed on the transition plate, and a second arc-shaped hole is formed on the second adjusting plate. A second screw passing through the round hole and the second arc-shaped hole can fix the fastener to the second adjusting plate. When it is necessary to adjust the inclination angle of the soil cover plate, the second screw can be loosened to adjust the position of the second adjusting plate. After the adjustment is completed, the second screw can be tightened.
[0016] Both sides of the transition plate and the soil cover plate have flanges. The flanges on both sides of the transition plate are folded in the same direction. The flanges on both sides of the soil cover plate are folded in opposite directions, and the lower flange is folded backward.
[0017] In addition, the movable seat also includes a central extension plate, which has a connecting hole at its front end and a first slot at its rear end. The front ends of both first U-shaped portions have second slots that engage with the first slots. The central extension plate is fixed relative to the first U-shaped portions by welding or other fixing methods. Furthermore, a first screw passes through the connecting hole in the central extension plate, thus effectively reinforcing the position of the transition plate.

Detailed Implementation
[0030] The invention will now be further described with reference to the accompanying drawings.
[0031] like Figure 1-3 The rut covering mechanism shown includes a fixed base 1 and two covering plates 2. Each covering plate 2 is connected to a first adjusting plate 3 with a first arc hole 31. The opening angle between the two covering plates 2 can be adjusted by the first adjusting plate 3. The two first adjusting plates 3 can be fixed by first screws 71 passing through the first arc holes 31 on both, so that the relative opening of the two covering plates 2 is fixed. In use, the fixed base 1 is mounted on a frame 10, which has multiple adjusting holes 10a. The fixed base 1 is connected to the positions of different adjusting holes 10a by screws, which can change the lateral position of the rut covering mechanism and realize the covering operation of ruts at different positions.
[0032] The wheel rut covering mechanism also includes a movable seat 4 and a transition plate 5; the movable seat 4 is connected to the fixed seat 1 through a height adjustment mechanism 6; the two transition plates 5 are rotatably mounted on the movable seat 4; each movable seat 4 is equipped with a covering plate 2, and a second adjustment plate 8 is fixed on the covering plate 2 to adjust the angle of the covering plate 2 relative to the transition plate 5; the relative rotation axis of the covering plate 2 and the transition plate 5 is horizontal, so that the inclination angle of the covering plate 2 can be adjusted.
[0033] The first adjusting plate 3 is fixedly installed relative to the transition plate 5. The opening and closing angle between the two transition plates 5 can be directly adjusted by the first adjusting plate 3 to indirectly adjust the angle between the two soil covering plates 2.
[0034] In the above structure, the height of the covering plate 2 is indirectly adjusted by the height adjustment mechanism 6 to adjust the amount of soil covering; the opening and closing angle of the covering plate 2 is indirectly adjusted by the first adjustment plate 3 to adjust the soil gathering range; and the tilt angle of the covering plate 2 is adjusted by the second adjustment plate 8 to adjust the soil compaction area of the covering plate 2, thereby adjusting the compaction after soil covering. Based on the above three-dimensional adjustment, the posture of the covering plate 2 can be effectively adjusted as needed to adapt to the wheel rut characteristics and soil covering requirements of different tractor models.
[0035] like Figure 2 As shown, the height adjustment mechanism 6 includes two parallel connecting rods 61, with each end of the connecting rod 61 hinged to the fixed seat 1 and the movable seat 4 respectively; the two connecting rods 61, the fixed seat 1, and the movable seat 4 together form a parallelogram linkage structure.
[0036] The height adjustment mechanism 6 also includes a telescopic adjustment unit 62 connecting the fixed base 1 and the movable base 4. The telescopic direction of the telescopic adjustment unit 62 is not parallel to the connecting rod 61. Thus, by changing the effective length of the telescopic adjustment unit 62, combined with the characteristics of the parallelogram linkage structure, the height of the movable base 4 can be changed while maintaining its posture, and the height of the movable base 4 has a large adjustment range, fully meeting adjustment needs.
[0037] The telescopic adjustment unit 62 includes a rod 621, a rotating seat 622, and an adjusting rod 623. One of the rod 621 and the rotating seat 622 is rotatably connected to the movable seat 4, and the other is rotatably connected to the fixed seat 1. In this embodiment, one end of the rod 621 is connected to the movable seat 4, and the rotating seat 622 is connected to the fixed seat 1. The adjusting rod 623 is screwed to the rod 621, and the adjusting rod 623 can rotate relative to the rotating seat 622. With this structure, rotating the adjusting rod 623 allows relative movement between the adjusting rod 623 and the rod 621, changing the relative position of the fixed seat 1 and the movable seat 4. To improve structural compactness, the rod 621 and one of the connecting rods 61 are coaxially hinged to the movable seat 4.
[0038] like Figure 5As shown, a rotary handle 624 is fixed on the adjusting rod 623. One end of the rotary handle 624 has a flower-shaped part a, and the other end has an annular groove b. The rotating seat 622 has an open groove c, and the edge of the open groove c is embedded in the annular groove b. In this way, the axial positioning of the rotary handle 624 can be achieved, and the installation of the rotary handle 624 is convenient.
[0039] like Figure 4 As shown, the movable seat 4 has a first U-shaped portion 41 provided for each of the transition plates 5, and also includes a second U-shaped portion 42 of the connecting rod portion 621; the first U-shaped portion 41 is vertically fixed to the back side of the bottom plate of the second U-shaped portion 42; the two first U-shaped portions 41 corresponding to the two transition plates 5 are arranged back to back, and the three U-shaped portions are welded and fixed together, so that the entire movable seat 4 has high strength; a first U-shaped bracket 51 rotatably connected to the first U-shaped portion 41 is fixed on the transition plate 5.
[0040] The transition plate 5 and the soil covering plate 2 are respectively fixed with a second U-shaped bracket 52 and a third U-shaped bracket 21, and the second U-shaped bracket 52 and the third U-shaped bracket 21 are rotatably connected by a rotating shaft.
[0041] In the above structure, the rotational connection between the components is established through the U-shaped part and the U-shaped bracket, which can effectively increase the hinge span and improve the reliability and stability of the connection between the components.
[0042] Furthermore, the movable base 4 also includes a central extension plate 43. The central extension plate 43 has a connecting hole at its front end and a first slot at its rear end. The front ends of both first U-shaped portions 41 each have a second slot that engages with the first slot. The central extension plate 43 is fixed relative to the first U-shaped portions 41 by welding or other fixing methods. A first screw 71 passes through the connecting hole of the central extension plate 43, thus effectively reinforcing the position of the transition plate 5.
[0043] like Figure 3 , 4 As shown, the central extension plate 43 is Y-shaped, with two forks at the front. Each fork has an indicator arrow d, and correspondingly, the first adjustment plate 3 has an indicator scale e.
[0044] The transition plate 5 is fixed with an L-shaped fastener 53 with a round hole. The second adjusting plate 8 has a second arc-shaped hole 81. The second screw 72, which passes through the round hole and the second arc-shaped hole 81, can fix the fastener 53 to the second adjusting plate 8. When it is necessary to adjust the inclination angle of the soil covering plate 2, the second screw 72 can be loosened to adjust the position of the second adjusting plate 8. After the adjustment is completed, the second screw 72 can be tightened.
[0045] Both sides of the transition plate 5 and the soil covering plate 2 have flanges. The flanges on both sides of the transition plate 5 are folded in the same direction. The flanges on both sides of the soil covering plate 2 are folded in opposite directions, and the lower flange is folded backward. This can maintain the structural strength and the flange direction is reasonable, which can meet the adjustment needs of the transition plate 5 and the soil covering plate 2 and the needs of acting on the soil.
[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
