[0002] Soil crushing is an important part of the soil remediation process, and plays a significant role in improving soil remediation efficiency and improving soil quality. Soil crushing mainly uses mechanical equipment to break large particles and lumps in the soil into smaller particles for subsequent processing and remediation. The main purpose of this step is to increase the surface area of the soil and improve the contact efficiency between the soil and the remediation agent, thereby accelerating the remediation process.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:
[0019] (1) A crushing and screening assembly is provided. By providing a first roller assembly, a second roller assembly and a third roller assembly, a three-stage crushing and screening structure is formed. The large-particle compacted soil blocks are crushed and screened by the first crushing blade, the second crushing blade and the third crushing blade in sequence, so that the soil is gradually crushed from a large-volume compacted state to a smaller particle state, thereby avoiding the problem that the traditional fixed-size crushing tool cannot stably crush a large-volume soil block at one time;
[0020] (2) The rotating motor drives the sprocket to rotate, and the sprocket drives the synchronous chain to move, so that the first crushing roller, the second crushing roller and the third crushing roller move together with the synchronous chain, and the first synchronous gear, the second synchronous gear and the third synchronous gear rotate under the meshing action of the synchronous rack, so that the first crushing roller, the second crushing roller and the third crushing roller can rotate while moving with the synchronous chain, so that the first crushing blade, the second crushing blade and the third crushing blade can effectively crush and cut the soil;
[0021] (3) The side wall spacings of adjacent first crushing rollers, the side wall spacings of adjacent second crushing rollers, and the side wall spacings of adjacent third crushing rollers are set from large to small, so as to achieve the technical effect of screening and crushing soil particles of different sizes. The volume of the larger compacted soil blocks is reduced under the crushing action of the first crushing blades, and they fall down through the gaps between the adjacent first crushing rollers, so as to achieve the initial crushing of the soil blocks. The second crushing blades will further crush the fallen soil blocks and reduce the volume of the soil particles. The soil particles crushed by the second crushing blades will be further crushed by the third crushing blades in the same way, so that the soil particles to be repaired are crushed and reduced step by step, and the crushing process is more stable.
[0022] (4) There may be a large number of stones, garbage or other large particles in the soil to be repaired that cannot be effectively crushed. They need to be screened out during the soil repair process. The first crushing roller, the second crushing roller and the third crushing roller achieve a step-by-step screening effect on large particles. Larger stones and other particles move upward with the first crushing roller and fall onto the rolling frame, and then fall into the first collection box through the rolling frame. Smaller stones and other particles fall below from the gap between the first crushing rollers and move upward with the second crushing roller. In the same way, they enter the second collection box from the rolling frame. Smaller particles are screened by the third crushing roller in the same way, achieving the technical effect of step-by-step screening of particles that cannot be crushed, thereby improving the problem of poor screening effect caused by only using single-stage screening in the traditional screening process;
[0023] (5) By setting up a soil-breaking component, the spike plate slides relative to the shovel plate under the control of an electric telescopic rod. When the device just starts to crush the soil, the spikes at the front end of the spike plate can be stably inserted into the compacted soil. The pulling frame is pulled and moved by a pulling vehicle to move the device as a whole, so that the spike plate and the shovel plate can turn over the compacted soil and perform preliminary crushing of the soil. The soil will move upward along the shovel plate to the position of the first crushing roller, thereby implementing a further crushing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Working principle and workflow:
[0050] The user first moves the device to the area where soil remediation is required, fixes the pulling rod 12 to the pulling vehicle, and the pulling vehicle can adopt existing technologies such as agricultural trailers or ordinary tractors, which will not be elaborated here. The pulling frame 1 is parallel to the ground, and the main controller 4 can be connected to the user's control end through a wire. The control end can be a control panel set in the cab of the towing vehicle. The user can send specific commands to the main controller 4 through the control panel in the cab, so as to effectively control the operation of other components of the device, or control the main controller 4 through a wireless remote control device, such as infrared or laser signal control, etc. Wired control panels or wireless infrared control are all existing technologies and will not be elaborated here.
[0051] The user controls the rotating motor 2125 to start through the main controller 4, and the rotating motor 2125 drives the sprocket 2122 to rotate, and the sprocket 2122 drives the synchronous chain 2123 to move, so that the first crushing roller 211, the second crushing roller 221 and the third crushing roller 231 move together with the synchronous chain 2123, and the first synchronous gear 2112, the second synchronous gear 2212 and the third synchronous gear 2312 rotate simultaneously under the meshing action of the synchronous rack 2124, so as to achieve the technical effect that the first crushing roller 211, the second crushing roller 221 and the third crushing roller 231 can rotate while moving with the synchronous chain 2123.
[0052] The user can control the electric telescopic rod 33 to start through the main controller 4. The spike plate 32 slides relative to the shovel board 31 under the push of the output end of the electric telescopic rod 33. The spikes at the front end of the spike plate 32 can stably insert into the compacted soil. When the device just starts to crush the soil, the user first controls the spike plate 32 set at the lower end of the first roller assembly 21 to slide and insert into the soil through the main controller 4. Then the user starts the traction vehicle to pull and move the traction frame 1 to move the device as a whole, so that the spike plate 32 and the shovel board 31 can turn over the compacted soil and perform preliminary crushing on the soil. The soil will move upward along the shovel board 31 to the position of the first crushing roller 211, thereby implementing a further crushing process. When the soil breaking assembly 3 set at the lower end of the second roller assembly 22 and the third roller assembly 23 moves to the position of the crushed soil, the electric telescopic rod 33 pushes the spike plate 32 to descend and insert into the crushed soil in the same way to further turn over and crush the soil.
[0053] When the soil contacts the first crushing roller 211, the first crushing roller 211 moves with the movement of the synchronous chain 2123, and rotates itself, so that the first crushing blade 2111 rotates. The side wall spacings of adjacent first crushing rollers 211, the side wall spacings of adjacent second crushing rollers 221, and the side wall spacings of adjacent third crushing rollers 231 are set from large to small. The volume of the larger compacted soil blocks is reduced under the crushing action of the first crushing blades 2111, and falls below through the gaps between the adjacent first crushing rollers 211, so that the soil is initially crushed. The second crushing blades 2211 will further crush the fallen soil blocks and reduce their volume. The soil particles crushed by the second crushing blades 2211 are further crushed by the third crushing blades 2311 in the same way, so that the soil particles to be repaired are crushed and reduced step by step, so as to achieve the technical effect of screening and crushing soil particles of different sizes, and the crushing process is more stable.
[0054] By setting the first roller assembly 21, the second roller assembly 22 and the third roller assembly 23, a three-stage crushing and screening structure is formed. The larger compacted soil blocks are crushed and screened by the first crushing blade 2111, the second crushing blade 2211 and the third crushing blade 2311 in sequence, so that the soil is gradually broken from a larger compacted state into a smaller particle state, avoiding the problem that traditional fixed-size crushing tools cannot stably crush larger soil blocks at one time.
[0055] There may be a large number of stones, garbage or other large-volume particles in the soil to be repaired that cannot be effectively crushed. They need to be screened out during the soil repair process. The first crushing roller 211, the second crushing roller 221 and the third crushing roller 231 can achieve a step-by-step screening effect on large-volume particles. Larger stones and other particles move upward with the first crushing roller 211 and fall onto the rolling frame 13, and fall into the first collecting box 14 through the rolling frame 13. Smaller stones and other particles fall below from the gap between the first crushing rollers 211, and move upward with the second crushing roller 221, and enter the second collecting box 15 from the rolling frame 13 in the same way. Smaller particles are screened by the third crushing roller 231 in the same way, and smaller particles will move upward with the third crushing roller 231 and fall into the third collecting box 16, achieving the technical effect of step-by-step screening of particles that cannot be crushed, thereby improving the problem of poor screening effect caused by only using single-stage screening in the traditional screening process.
