Description

Technical Field

[0001] This utility model belongs to the technical field of soil remediation devices, specifically relating to a soil remediation and leveling device. Background Technology

[0002] In the field of soil remediation, "soil turning and breaking up + leveling and compaction" is a key process for remediating contaminated soil and improving compacted soil. By turning the soil, the compacted layer is broken up, and then leveling ensures that the soil layer thickness is uniform and the surface is flat, laying the foundation for subsequent planting or ecological restoration. Currently, soil remediation leveling devices mainly rely on "fixed spreading plates" or "passive rolling rollers" to achieve the leveling function, but both have technical defects and cannot meet the requirements for efficient and high-quality soil leveling.

[0003] Firstly, the fixed leveling plate structure results in poor leveling effect and low adaptability. The leveling component of traditional devices is mostly a metal plate at a fixed angle, which scrapes the soil surface by pushing the device as it moves. The core problem is that "passive leveling cannot adapt to soil undulations": when there are raised soil clods, the fixed leveling plate can only push the soil clods to the sides, but cannot press them into the depressions below, resulting in uneven surfaces after leveling.

[0004] Secondly, the passive rolling roller structure results in uneven soil compaction and a tendency to miss areas during leveling. Some devices use cylindrical rolling rollers instead of fixed spreading plates, achieving leveling by compacting the soil with the roller's own weight. However, the drawback of this type of structure is that compaction alone cannot solve the problem of filling local depressions: the rolling roller has limited compaction effect on protruding soil clods, and the small contact area between the roller and the soil makes it impossible to push dispersed soil particles into the depression areas, resulting in a problem of "local looseness and local compaction" in the leveled soil. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a soil remediation and leveling device that solves the problems of poor leveling effect and low adaptability of existing soil remediation and leveling devices, uneven soil compaction and easy omissions in passive rolling roller structures, and poor coordination between soil turning and leveling, resulting in low overall work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil remediation and leveling device, comprising a traction frame, on which a soil-turning wheel mechanism, a lifting frame, and a leveling mechanism are mounted. Wheels are mounted on the lifting frame. The leveling mechanism is located behind the soil-turning wheel mechanism. The leveling mechanism includes a support frame, which is fixedly mounted on the traction frame and has a reduction motor fixedly mounted on it. A rotating disk is mounted on the output shaft of the reduction motor. An eccentric shaft fixedly mounted on the rotating disk rotatably connects one end of a connecting rod. The other end of the connecting rod is rotatably connected to one end of a connecting rod 2 and a rocker arm 1 via a pin. The other end of the connecting rod 2 is rotatably connected to one end of a rocker arm 2 via a pin. A rotating rod is fixedly mounted on the other end of both rocker arms 1 and 2. The rotating rod is rotatably mounted on the traction frame and has a lever fixedly mounted on it.

[0007] The beneficial effects of this utility model are as follows: the soil fragments broken by the soil turning wheel mechanism are spread evenly by the reciprocating shovel in the spreading mechanism. Compared with the fixed spreading plate structure, the actively reciprocating shovel can make the raised blocks better fill the depressed soil layer, thus improving the spreading effect.

[0008] To facilitate the movement of the device;

[0009] As a further improvement to the above technical solution: the lifting frame includes a second hydraulic cylinder, the two ends of the second hydraulic cylinder are rotatably connected to a traction frame and a second connecting ear respectively through a pin shaft, the second connecting ear is fixed on a support shaft, the support shaft is rotatably mounted on the traction frame and the two ends of the support shaft are fixedly connected to one end of a connecting arm, and the other end of the connecting arm is rotatably mounted with a wheel.

[0010] The beneficial effects of this improvement are: when the hydraulic cylinder extends, the connecting rod mechanism can drive the wheel to move downwards towards the traction frame, thereby making the wheel lower than the turning wheel mechanism to provide reliable rolling support for the whole device and ensure the stability of the device's movement.

[0011] To ensure the stability of the rotation of the two levers;

[0012] As a further improvement to the above technical solution: the two dials are arranged in parallel to each other.

[0013] The beneficial effect of this improvement is that the two levers can rotate in parallel under the traction of the connecting rod 2, effectively leveling the soil.

[0014] To facilitate the adjustment of the tilling depth of the tilling wheel mechanism;

[0015] As a further improvement to the above technical solution: the soil turning wheel mechanism includes a hydraulic cylinder, the two ends of which are rotatably connected to a traction frame and a connecting ear, respectively, via pins. The connecting ear is fixed on a crossbar, and a connecting shaft is fixed on the crossbar. The connecting shaft is rotatably installed in a fixed seat, and the fixed seat is fixed on the traction frame.

[0016] The beneficial effects of this improvement are: when the hydraulic cylinder extends or retracts, it can drive the crossbar to rotate around the axis of the connecting shaft under the support of the fixed seat, thereby adjusting the position of the lower soil-turning wheel and changing the soil-turning depth of the soil-turning wheel mechanism.

[0017] To ensure the safety of the soil turning mechanism;

[0018] As a further improvement to the above technical solution: one end of a U-shaped spring plate is fixedly connected to both ends of the crossbar, and a connecting seat is fixedly provided at the other end of the U-shaped spring plate. The connecting seat is rotatably connected to both ends of the soil turning wheel.

[0019] The beneficial effects of this improvement are: when the soil turning wheel is obstructed by hard objects such as stones, the U-shaped spring plate undergoes elastic deformation under the drive of the soil turning wheel, causing the soil turning wheel to move upward and avoid the stones, effectively ensuring the soil turning safety of the soil turning wheel mechanism.

[0020] To ensure the structural stability of the device;

[0021] As a further improvement to the above technical solution: the traction frame is a frame structure composed of multiple welded steel pipes.

[0022] The beneficial effects of this improvement are: the traction frame has a simple structure and can provide stable support for the entire device.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] Example 1:

[0031] like Figure 1As shown in Figure 4: A soil remediation and leveling device includes a traction frame 1, on which a soil-turning wheel mechanism 3, a lifting frame 4, and a leveling mechanism 5 are mounted. Wheels 2 are mounted on the lifting frame 4. The leveling mechanism 5 is located behind the soil-turning wheel mechanism 3. The leveling mechanism 5 includes a support 51, which is fixed to the traction frame 1 and has a reduction motor 52 fixed on it. A rotating disk 53 is mounted on the output shaft of the reduction motor 52. An eccentric shaft fixed on the rotating disk 53 rotatably connects one end of a connecting rod 54. The other end of the connecting rod 54 is rotatably connected to one end of a connecting rod 55 and a rocker arm 56 via a pin. The other end of the connecting rod 55 is rotatably connected to one end of a rocker arm 57 via a pin. The other end of each rocker arm 57 is fixed with a rotating rod 58. The rotating rod 58 is rotatably mounted on the traction frame 1, and a lever 59 is fixed on the rotating rod 58. Soil fragments broken by the soil turning wheel mechanism 3 are spread evenly by the lever 59 reciprocating in the spreading mechanism 5. Compared with a fixed spreading plate structure, the actively reciprocating lever 59 can make the raised bumps better fill the depressed soil layer, improving the spreading effect. The lifting frame 4 includes a hydraulic cylinder 41. The two ends of the hydraulic cylinder 41 are rotatably connected to the traction frame 1 and the connecting ear 42 respectively by a pin. The connecting ear 42 is fixed on the support shaft 43. The support shaft 43 is rotatably mounted on the traction frame 1, and one end of the connecting arm 44 is fixedly connected to both ends of the support shaft 43. The end is rotatably mounted with a wheel 2. When the second hydraulic cylinder 41 extends, it can drive the wheel 2 to move downwards from the traction frame 1 via a linkage mechanism, thereby lowering the wheel 2 below the soil-turning wheel mechanism 3 to provide reliable rolling support for the entire device and ensure the stability of the device's movement. The two lever plates 59 are arranged parallel to each other and can maintain parallel rotation under the traction of the second connecting rod 55, effectively leveling the soil. The soil-turning wheel mechanism 3 includes a first hydraulic cylinder 31. The two ends of the first hydraulic cylinder 31 are rotatably connected to the traction frame 1 and the first connecting ear 32 respectively via pins. The first connecting ear 32 is fixed on the crossbar 33, and a connecting shaft 34 is fixed on the crossbar 33. The connecting shaft 34 is rotatably mounted in the fixed seat 38, and the fixed seat 38 is fixed on the traction frame 1. The first hydraulic cylinder 31 During extension and retraction, the crossbar 33 can be driven by the connecting ear 32 to rotate around the axis of the connecting shaft 34 under the support of the fixed seat 38, thereby adjusting the position of the lower turning wheel 37 and changing the turning depth of the turning wheel mechanism 3. The two ends of the crossbar 33 are fixedly connected to one end of the U-shaped spring plate 35, and the other end of the U-shaped spring plate 35 is fixedly provided with a connecting seat 36. The connecting seat 36 rotatably connects the two ends of the turning wheel 37. When the turning wheel 37 is obstructed by hard objects such as stones, the U-shaped spring plate 35 is elastically deformed under the drive of the turning wheel 37, causing the turning wheel 37 to move upward to avoid the stones, effectively ensuring the turning safety of the turning wheel mechanism 3. The traction frame 1 is a frame structure composed of multiple welded steel pipes. The traction frame 1 has a simple structure and can provide stable support for the whole device.

[0032] The working principle of this technical solution is as follows: The traction frame 1 is connected to an external traction device such as a tractor. The hydraulic cylinder 41 of the lifting frame 4 is extended, causing the support shaft 43 and connecting arm 44 to rotate. The wheel 2 descends to contact the ground and supports the entire device. The traction device moves the device to the edge of the repair plot. Upon reaching the starting point, the hydraulic cylinder 41 is retracted, the wheel 2 rises, and the turning wheel 37 and the lever 59 descend to the set height. The traction device is then activated, moving at a constant speed along the working direction. The turning wheel 37 moves and rolls with the device, cutting into the soil and breaking up the compacted / contaminated layer, loosening the soil into a straight layer. For smaller fragments, the U-shaped spring plate 35 elastically deforms when it encounters hard objects such as stones, causing the soil turning wheel 37 to move upwards to avoid damage to the components. After turning, the soil fragments enter the working area of ​​the leveling mechanism 5 as the device moves: the reduction motor 52 drives the rotating disk 53 to rotate continuously, pulling the rocker arm 56 through the connecting rod 1 54, and at the same time pushing the rocker arm 57 through the connecting rod 2 55, so that the two rotating rods 58 drive the dial plate 59 to swing back and forth. During the swinging process, the dial plate 59 pushes the protruding soil clods to the depressions on both sides, and at the same time further breaks up the large pieces of soil, so as to achieve a flat soil surface.
