The leaching mechanism is arranged at the top of the shell, the conveying mechanism is arranged in the shell, and the conveying mechanism is arranged below the leaching mechanism. An inlet and an outlet are provided between the leaching mechanism and the conveying mechanism. The shell is mounted on the bottom plate, and a recovery chamber with a top opening is provided between the bottom plate and the conveying mechanism. By utilizing the leaching mechanism and the conveying mechanism, when leaching heavy metal soil on the conveying mechanism, not only can the soil be fully leached, but also sewage infiltrated from the soil can be collected to prevent secondary pollution. Moreover, due to the cooperation between the fixed-point spraying leaching mechanism and the dynamic conveying mechanism, the leaching method is more reasonable, the leaching area of the soil is increased, the leaching efficiency is improved, and the soil repair rate is improved.

[0003] The soil improvement washing device in the above patent has the following shortcomings: it cannot disperse the soil in blocks. Since the soil has a certain adhesion, it will pile up together during transportation and then dry into larger lumps. If the soil lumps are not dispersed and washed directly, the soil lumps will not be fully washed by the cleaning solution, resulting in unsatisfactory washing effect and affecting the repair effect. Therefore, it is necessary to design a washing device for soil heavy metal remediation to solve the above problems. Utility Model Content

The second spring is sleeved on the second limit rod, and the U-shaped plate is fixedly connected to one of the support plates. Since the technical means of vibrating and screening the soil while transporting the soil is adopted, the vibrating soil can make the dry lumps of soil collide with each other or be dispersed by the device screening box, so that the soil blocks are dispersed into smaller blocks, and finally fall onto the conveyor belt through the screen of the screening box for transportation, which effectively solves the problem that the soil blocks cannot be dispersed in the background technology. Since the soil has a certain adhesion, it will accumulate together during transportation and then dry into larger soil blocks. If the soil blocks are not dispersed and are directly leached, the soil blocks will not be fully leached by the cleaning solution, resulting in unsatisfactory leaching effect and affecting the repair effect. The problem of being able to disperse the dry lumps of soil, ensuring that the soil can be fully leached by the cleaning solution, and ensuring the technical effect of the repair effect is achieved.

[0013] The beneficial effects of the utility model are:

[0014] The utility model adopts a technical means of vibrating and screening the soil while transporting it, so the vibrating soil can make the dry soil in blocks collide with each other or be dispersed by the device screening box, so that the soil blocks are dispersed into smaller blocks, and finally fall onto the conveyor belt through the screen of the screening box for transportation, which effectively solves the problem that the soil blocks cannot be dispersed in the background technology.

Since the technical means of vibrating and screening the soil while transporting the soil is adopted, the vibrating soil can make the dry and lumpy soil collide with each other or be dispersed by the device screening box, so that the soil blocks are dispersed into smaller blocks, and finally fall onto the conveyor belt through the screen of the screening box for transportation, which effectively solves the problem that the soil blocks cannot be dispersed in the background technology. Since the soil has a certain adhesion, it will accumulate together during transportation and then dry into larger soil blocks. If the soil blocks are not dispersed and are directly leached, the soil blocks will not be fully leached by the cleaning solution, resulting in unsatisfactory leaching effect and affecting the repair effect. The problem is achieved by being able to disperse the dry and lumpy soil, ensuring that the soil can be fully leached by the cleaning solution, and ensuring the technical effect of the repair effect.

[0024] In this embodiment, the two circular plates 11 are fixedly connected to a first synchronous wheel 16 on the side close to each other, the first synchronous wheel 16 is provided with a synchronous belt 17, and the synchronous belt 17 is provided with a second synchronous wheel 18 on the end away from the first synchronous wheel 16. The two second synchronous wheels 18 are fixedly connected to the same cleaning brush 19 on the side close to each other, and both ends of the cleaning brush 19 pass through the outer shell 1, and the cleaning brush 19 is rotatably connected to the outer shell 1.

[0025] In this embodiment, the two first synchronous wheels 16 at the same end are fixedly connected to the same rotating shaft 20 on the side close to each other. Both ends of the rotating shaft 20 pass through the outer shell 1. The rotating shaft 20 is rotatably connected to the outer shell 1. The two rotating shafts 20 are both covered with the same conveyor belt 21.

[0026] In this embodiment, a plurality of drainage holes 22 are formed on the conveyor belt 21 .

[0027] In this embodiment, a recovery box 23 is provided at the bottom of the conveyor belt 21 , a water outlet pipe is provided on one side of the recovery box 23 , a valve is provided on the water outlet pipe on the recovery box 23 , and the recovery box 23 is arranged inside the shell 1 .

[0028] In this embodiment, a liquid storage tank 24 is fixedly connected to the top of one end of the housing 1 , and a water inlet pipe 25 is provided on the top of the liquid storage tank 24 .

[0029] In this embodiment, a water pump is provided inside the liquid storage tank 24, and water pipes 27 are fixedly connected to the water outlets on both sides of the water pump in the liquid storage tank 24. The water pipes 27 pass through the liquid storage tank 24 and the outer shell 1. The two water pipes 27 are fixedly connected to the same sprinkler head 26, and the sprinkler head 26 is fixedly connected to the top inner wall of the outer shell 1.

[0030] Working principle: When using this device, the cleaning solution can be injected into the liquid storage tank 24 through the water inlet pipe 25, and then the soil to be washed is injected into the screening box 10, and the soil is screened by the screening box 10, and finally falls onto the conveyor belt 21 through the screen on the screening box 10, and then the motor 5 is started, and the output end of the motor 5 will drive the circular plate 11 to rotate, and the circular plate 11 will drive the first synchronous wheel 16 to rotate, and the first synchronous wheel 16 will drive the rotating shaft 20 to rotate, and the rotating shaft 20 will drive the conveyor belt 21 to rotate to transport the soil, and transport the soil to the position of the spray head 26, and then start the water pump in the liquid storage tank 24 to extract the cleaning solution in the liquid storage tank 24, and transport it to the spray head 26 through the water pipe 27, and finally spray it. The head 26 sprays to rinse the soil, and the rinsed soil will be transported away from the device by the conveyor belt 21. The cleaning solution will fall into the recovery box 23 through the drain hole 22 and be collected, which is convenient for the treatment of the used cleaning solution. The valve on the outlet pipe of the recovery box 23 can be opened to discharge the cleaning solution. When the first synchronous wheel 16 rotates, it will also drive the synchronous belt 17 to rotate, and the synchronous belt 17 will drive the second synchronous wheel 18 to rotate. The second synchronous wheel 18 will drive the cleaning brush 19 to rotate to scrub and clean the surface of the conveyor belt 21. When the circular plate 11 rotates, it will also drive the first convex plate 12 to do a circular motion. When the first convex plate 12 contacts the second convex plate 15, it will squeeze the second convex plate 15 to move one end of the second convex plate 15. When the first convex plate 12 contacts the second convex plate 15 at the top, the second convex plate 15 will move a distance toward the liquid storage tank 24. When the first convex plate 12 contacts the second convex plate 15 at the bottom, the second convex plate 15 will move a distance away from the liquid storage tank 24. The second convex plate 15 can be reciprocated while the conveyor belt 21 rotates. The reciprocating movement of the second convex plate 15 will drive the U-shaped plate 28 to move, and the U-shaped plate 28 will drive one of the support plates 7 to move, and the support plate 7 will drive the supporting plate 9 to move, and the movement of the supporting plate 9 will drive the screening box 10 to move back and forth, so that the soil in the screening box 10 collides with each other and is scattered, and finally falls onto the conveyor belt 21 through the screen on the screening box 10. The movement of the support plate 7 will move along the first limit rod 6, which can ensure the stability of the screening box 10 during movement. The movement of the support plate 7 will squeeze the first spring 8 to shrink the first spring 8. When the first convex plate 12 does not contact the second convex plate 15, the first spring 8 will also extend, which can make the support plate 7 reciprocate, and also can make the supporting plate 9 reciprocate, and the supporting plate 9 makes the screening box 10 reciprocate.
