DETAILED DESCRIPTION

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, such as Figures 1-4 The present invention provides the following technical solution to address the problem of clogging during soil treatment, which affects soil treatment efficiency: A crushing mechanism is disclosed, comprising a housing 1, a sprayer 2 mounted on the side of the housing 1, a conveying assembly 3 connected inside the housing 1, and a dispersing assembly 4 connected inside the housing 1 away from the conveying assembly 3. A small gear 101 is rotatably connected to the side of the housing 1 near the driving device of the dispersing assembly 4. The dispersing assembly 4 includes a driving device, two meshing large gears, and two crushing rods. The small gear 101 is meshed with the large gears of the dispersing assembly 4. A first pulley 102 is fixed to the side of the small gear 101 away from the housing 1, and a transmission belt 103 is connected to the surface of the first pulley 102. A crushing mechanism to prevent soil clogging is provided on the side of the housing 1. A guide groove 111 is provided on the side of the housing 1 near the small gear 101, and the guide groove 111 is oriented left-right about the center of the housing 1. The guide groove 111 is symmetrically distributed and has a sliding mechanism inside to reduce the power consumption of the crushing mechanism. The crushing mechanism includes a second pulley 104, which is connected to the inner side of the transmission belt 103 away from the first pulley 102. A rotating rod 105 is fixed to the side of the second pulley 104 near the housing 1. The rotating rod 105 rotates through the second outer block 107 and the first connecting block 106. The first connecting block 106 and the second outer block 107 are both fixed to the outside of the housing 1, and the second outer block 107 and the first connecting block 106 are located on the same side of the housing 1. An extrusion block 108 is rotatably connected to the end of the rotating rod 105 away from the second pulley 104. An extrusion plate 109 is symmetrically rotatably connected to the inner side of the feed inlet of the housing 1. A fixing rod 110 is fixed to the center position of the extrusion plate 109 near the side of the housing 1. The fixing rod 110 slides through the extrusion block 108 and moves inside the second outer block 107.

[0032] When the treatment device is in use, the contaminated soil can be poured into the inlet of the housing 1. The soil is broken up by the dispersing component 4 inside the inlet, and the broken soil falls onto the surface of the conveying component 3. The conveying component 3 then conveys the soil out of the housing 1. During the conveying process, the sprayer 2 can spray the treatment solution onto the surface of the broken soil, thus achieving chemical treatment of the soil. Metal-contaminated soil may form large clumps, which may fall into the inlet of the housing 1 and cause blockage. During the operation of the dispersing component 4, the drive device drives the large gear to rotate, which in turn drives the two symmetrical crushing rods to rotate. When the large gear rotates, it drives the small gear 101 to mesh and rotate. When the small gear 101 meshes and rotates, it can rotate through the housing 1. When the small gear 101 rotates, it drives the first pulley 102 to rotate, which in turn drives the transmission belt 103 to rotate. When the transmission belt 103 rotates, it can drive the second pulley 104 to rotate. When the second pulley 104 rotates, it can drive the rotating rod 105 to rotate. When the rotating rod 105 rotates, it can rotate through the first connecting block 106 and the second external connecting block 107. When the rotating rod 105 rotates, it can drive the extrusion block 108 to rotate. When the extrusion block 108 rotates, it can extrude pressure on the surface of the fixed rod 110. At the same time, the extrusion block 108 can slide on the surface of the fixed rod 110. During the extrusion process, the extrusion block 108 will rotate through the rotating rod 105. When the fixed rod 110 is extruded, it can drive the extrusion plate 109 to rotate. When the extrusion plate 109 rotates, it can rotate through the inside of the housing 1. When the two extrusion plates 109 rotate, they can extrude the condensed contaminated soil inside the feed inlet of the housing 1. After the soil is extruded, it can fall into the housing 1 in pieces and be broken by the disintegration component 4, thereby preventing the soil from clogging the feed inlet of the treatment device.

[0033] Example 2, as follows Figure 3 , Figure 5 and Figure 6 The present invention provides the following technical solution: In order to solve the problem of increased power consumption of the soil treatment device due to the long-term operation of the crushing mechanism, a sliding mechanism is disclosed based on the first embodiment: The sliding mechanism includes a threaded block 112, which slides inside the guide groove 111. A bidirectional threaded rod 113 is rotatably inserted through the housing 1, the guide groove 111, and the threaded block 112. The bidirectional threaded rod 113 is threadedly connected to the threaded block 112. A sliding block 114 is fixed at the bottom of the threaded block 112. The sliding block 114 slides through the guide groove 111. A small gear 101 is rotatably connected to the side of the sliding block 114 away from the housing 1.

[0034] When the soil does not have large clumps, the operator can rotate the bidirectional threaded rod 113. When the bidirectional threaded rod 113 rotates, it can rotate through the housing 1 and the guide groove 111. When the bidirectional threaded rod 113 rotates, it can drive the two threaded blocks 112 to slide. When the threaded blocks 112 slide, they can move in opposite directions. When the threaded blocks 112 move, they can drive the sliding block 114 to move. When the sliding block 114 moves, it can slide through the guide groove 111. When the two sliding blocks 114 slide, they can drive the two small gears 101 to move. When the two small gears 101 move, they can move away from the large gear of the dispersing component 4. At this time, the small gears 101 do not contact the large gear of the dispersing component 4. When the small gears 101 do not contact, the load intensity of the dispersing component 4 drive device can be reduced, thereby reducing the power consumption of the treatment device during operation. This allows the treatment device to select the opening and closing of the crushing mechanism according to the actual soil conditions, improving the practicality of the treatment device.

[0035] Example 3, as follows Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem of rapid wear of parts in soil remediation devices: A rolling mechanism is disclosed: a rolling mechanism to reduce wear is provided inside the sliding block 114. The rolling mechanism includes a rotating groove 115, symmetrically located at the bottom of the sliding block 114. A roller 116 is rotatably connected inside the rotating groove 115. The roller 116 is rolled and fitted inside the guide groove 111. When the crushing mechanism of the remediation device is opened or closed, the bidirectional threaded rod 113 is rotated to drive the sliding block 114 to slide inside the guide groove 111. When the sliding block 114 moves, it can drive the roller 116 to move. When the roller 116 moves, it can generate friction with the inner wall of the guide groove 111. When the roller 116 is subjected to friction, it can rotate through the rotating groove 115. When the roller 116 rotates, it can roll on the inner wall of the guide groove 111. The rolling of the roller 116 can reduce the frictional wear caused by the sliding block 114 inside the guide groove 111, thereby indirectly improving the quality of the remediation device.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
