This structure can discharge impurities in the cleaning box 14 through the sewage outlet 13, and the drain port 7 is used to discharge excess cleaning water. At the same time, the cleaning box 14 can supply water to the spray washing pipe 6 through the drain port 7, so that the engineering materials can be rinsed. The guide plate 18 can guide the rinsed engineering materials into the spin-drying separation drum 9. The spin-drying separation drum 9 rotates under the drive of the outer gear ring and the motor. Through centrifugal force, the removed water is discharged from the dehydration mesh 10. A support roller 16 is also rotatably installed in the cleaning box 14, and the support roller 16 is arranged in parallel with the lower pressure roller 3, and the lower pressure roller 3 and the support roller 16 are respectively located on the inner and outer sides of the upper layer of the conveyor belt 15. The roller 3 and the support roller 16 are staggered, and the farthest position of the downward pressure roller 3 is lower than the lower end plane of the support roller 16. This structure enables the support roller 16 to support the upper layer of the conveyor belt 15 when the downward pressure roller 3 presses down the conveyor belt 15, so that a groove can be formed on the conveyor belt 15. A spray pipe 6 is installed on the upper end of the cleaning box 14, and the water outlet of the spray pipe 6 faces the conveyor belt 15. The conveyor belt 15 is evenly spaced with a mesh structure, and the conveyor belt 15 is also evenly spaced with anti-skid protrusions 17 of an integrated structure. This structure allows the conveyor belt 15 to be leaked through the mesh, and the anti-skid protrusions 17 can prevent the engineering materials from slipping off the conveyor belt 15, so that the inclined conveyor belt 15 can be used for the conveyance of engineering materials.A spin-drying separation drum 9 is rotatably installed in the installation box 23, and a dehydration mesh 10, a first separation mesh 11 and a second separation mesh 12 are provided on the spin-drying separation drum 9.

The lifting hydraulic cylinder 4 drives the U-shaped mounting part 5 to move downward, so that the lower pressure roller 3 presses down the upper conveyor belt 15. The limit rod 25 moves under the positioning of the fixed plate 24 to achieve the stable movement of the lower pressure roller 3. The supporting roller 16 supports the conveyor belt 15 so that a part of the conveyor belt 15 is pressed down to form a groove for soaking. At this time, the engineering materials are soaked in the cleaning box 14. After a period of time, the lower pressure roller 3 moves up again, and the conveyor belt 15 is driven to rotate by the transmission roller 8, so that the conveyor belt 15 conveys the soaked engineering materials to the bottom of the spray pipe 6. The anti-slip protrusion 17 is used to prevent the engineering materials from sliding down. The spray pipe 6 rinses the engineering materials. The engineering materials fall into the cleaning box 14 through the mesh of the conveyor belt 15, and are finally discharged from the sewage outlet 13. The drainage outlet 7 is used for drainage treatment of the cleaning box 14. After being rinsed, the engineering materials fall onto the guide plate 18 from the conveyor belt 15, and are then introduced into the spin-drying separation drum 9 by the guide plate 18. The spin-drying separation drum 9 is rotated and driven by the cooperation of the motor and the outer gear ring under the positioning of the installation box 23 to achieve centrifugal dehydration. The removed water is thrown out by the dehydration mesh 10 and discharged through the dehydration drainage outlet 19. The engineering materials are screened when passing through the first separation mesh 11 and the second separation mesh 12. The screened engineering materials are discharged from the first discharge port 21 and the second discharge port 22 for collection, and the engineering materials discharged from the end of the spin-drying separation drum 9 are also directly discharged for collection. The partition plate 20 can prevent the removed water from flowing to the discharge port, thereby realizing the efficient cleaning and separation operation of the cleaning and classification device body 1 on the engineering materials, thereby completing a series of tasks.
