[0002] Soil pollution is characterized by its hidden nature, delayed effects, and difficulty in remediation, making it a hot topic and a challenge in the field of environmental science.

[0003] Existing soil washing remediation devices typically involve feeding soil into a filter drum and mixing it with a washing solution for washing. During the washing process, when the spraying device sprays the washing solution onto the top of the drum, the damp soil in the rotating filter drum tends to stick to the screen wall, and soil particles can easily get stuck in the mesh, causing clogging and affecting the filtration of the soil. Furthermore, clogging of the filter drum mesh can also restrict the flow of the washing solution into the drum, impacting the washing effect on the soil. Summary of the Invention

[0004] The purpose of this invention is to provide a soil washing device for soil remediation, so as to solve the problem that the filter drum is easily clogged in the prior art, which affects the soil washing effect.

[0019] 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.

[0020] Example: Figure 1 - Figure 4 As shown, the following technical solution is provided: a soil washing device for soil remediation, including a housing 1, a filter cylinder 4 disposed inside the housing 1, a transmission gear 6 fixedly connected to one end of the filter cylinder 4, cleaning rollers 7 disposed on both sides of the top of the filter cylinder 4, rotating rods 11 disposed on opposite sides of the two cleaning rollers 7, and multiple rotating rods 11 fixedly connected to the outer sides of the two rotating rods 11. Cleaning rollers 7 are provided on both sides of the top of the filter cartridge 4. Rotating rods 11 are provided on opposite sides of the two cleaning rollers 7. Multiple cams 13 are fixedly connected to the outer side of the two rotating rods 11. Motion rods 14 adapted to the cams 13 are provided on one side of the multiple cams 13. Multiple striking blocks 15 are fixedly connected to the outer side of the multiple motion rods 14 in a linear array. The rotation of the transmission gear 6 drives the cleaning rollers 7 to rotate and clean the outer side of the filter cartridge 4. When the cams 13 rotate, the multiple protrusions of the cams 13 contact the motion rods 14 in sequence, driving the motion rods 14 to move upward.

[0021] Both cleaning rollers 7 are rotatably installed inside the housing 1. A first gear 8 is fixedly connected to one side of each of the two cleaning rollers 7. A second gear 9 is meshed with one side of each of the two first gears 8. A third gear 10 is meshed with one side of one of the second gears 9. Both first gears 8 are meshed with the transmission gear 6. When the transmission gear 6 rotates, it drives the cleaning rollers 7 to rotate and clear the sieve holes of the filter cartridge 4.

[0022] Both rotating rods 11 are rotatably installed inside the housing 1. One end of each rotating rod 11 is fixedly connected to a fourth gear 12. One of the fourth gears 12 is meshed with a third gear 10, and the other fourth gear 12 is meshed with one of the second gears 9. The third gear 10 and the two second gears 9 are rotatably installed on one side inside the housing 1.

[0023] The moving rod 14 is fixedly connected to two sliders 16 at both ends. Each slider 16 is slidably connected to a limit rod 17. The tops of the two limit rods 17 are fixedly connected to the housing 1. A spring 18 is fixedly connected between the tops of the two sliders 16 and the housing 1. During operation, the moving rod 14 moves upward and compresses the spring 18. When the protrusion of the cam 13 is not in contact with the moving rod 14, the moving rod 14 descends rapidly under the action of the spring 18, thereby causing the striking block 15 to strike the filter cylinder 4, shaking off the soil impurities inside the screen holes and preventing the screen holes inside the filter cylinder 4 from becoming clogged.

[0024] Inside the housing 1, a rotating shaft 2 is rotatably installed. Multiple fixing brackets 3 are fixedly connected to the outside of the rotating shaft 2. The multiple fixing brackets 3 are fixedly connected to the inner wall of the filter cartridge 4. Spiral blades 5 are fixedly connected inside the filter cartridge 4. A second motor 23 is fixedly connected to one side of the housing 1. The output end of the second motor 23 is fixedly connected to the rotating shaft 2.

[0025] A diversion plate 19 is fixedly connected to the top of the housing 1, and multiple spray heads 20 are fixedly connected to the top of the inside of the housing 1. The tops of the multiple spray heads 20 all penetrate the housing 1 and are connected to the diversion plate 19.

[0026] A spiral conveyor rod 21 is rotatably installed at the bottom of the box 1. A first motor 22 is fixedly connected to one side of the box 1. The output end of the first motor 22 is fixedly connected to the spiral conveyor rod 21. A feeding funnel 24 is fixedly connected to the rear side of the box 1. A discharge port 25 is provided on the front side of the box 1. A collection port is provided on the rear bottom side of the box 1. The washed mud is collected by the spiral conveyor rod 21.

[0027] In use, the soil enters the filter cylinder 4 through the feeding funnel 24. The second motor 23 drives the filter cylinder 4 to rotate through the rotating shaft 2, causing the soil inside the filter cylinder 4 to roll continuously. While the filter cylinder 4 is rotating, multiple spray heads 20 wash the soil particles inside the filter cylinder 4. The soil particles are impacted by the water into mud. The mud passes through the sieve holes of the filter cylinder 4 and flows into the bottom of the box 1 along the inclined surface inside the box 1. The filter cylinder 4 is fixedly connected with a spiral blade 5. The rotation of the spiral blade 5 pushes large particles such as stones that cannot be washed into mud to the front end of the filter cylinder 4 for collection.

[0028] As the filter cartridge 4 rotates, it drives the transmission gear 6 to rotate. The transmission gear 6, through the first gear 8, drives the cleaning rollers 7 to rotate. The two cleaning rollers 7 clean the sieve holes of the filter cartridge 4 to prevent impurities and damp mud from clogging the filter cartridge 4. At the same time, the rotation of the first gear 8 drives the two second gears 9 and the third gear 10 to rotate the two rotating rods 11, thereby driving the multiple cams 13 to rotate. When the cams 13 rotate and their convex surfaces move, they drive the moving rod 14 to move upward and compress the spring 18. When the cam 13 engages with the moving rod 14... When the protrusion of the contact point disengages from the moving rod 14 during rotation, the moving rod 14 descends rapidly under the action of the spring 18. At this time, the striking block 15 strikes the outside of the filter cylinder 4. Subsequently, the other protrusions of the cam 13 continue to drive the moving rod 14 upward, repeating the previous movement. As the filter cylinder 4 rotates to screen the slurry, the cam 13 drives the striking block 15 to continuously strike the filter cylinder 4, shaking off the soil and impurities on the top of the inner side of the filter cylinder 4. This prevents soil and impurities from clogging and sticking to the screen holes of the filter cylinder 4, affecting the washing effect of the spray head 20 on the soil. The washed slurry falls into the bottom of the box 1 through the screen holes of the filter cylinder 4. The first motor 22 works to drive the screw conveyor 21 to rotate, causing the slurry to flow through the collection port to the subsequent slurry treatment device.
