[0002] Manufactured sand refers to rock, mine tailings, or industrial waste particles with a diameter of less than 4.75 mm, produced by mechanical crushing and screening after soil removal. It does not include soft or weathered particles and is commonly known as artificial sand. Manufactured sand has a wide range of sources, utilizing various waste resources such as mine tailings and industrial waste, which are then appropriately sorted and processed to produce sand that meets the required specifications.

Multiple movable plates 8 are distributed around the central axis of the rotating roller 7. The movable plates 8 cooperate with multiple mating grooves 9 opened on the rotating roller 7. Multiple protrusions 10 are connected to the movable plates 8. The protrusions 10 are all conical in shape. Multiple first elastic elements 11 are distributed. The two ends of the first elastic elements 11 are connected to the mating grooves 9 and the movable plates 8, respectively. The first elastic elements 11 are selected from, but are not limited to, springs. The number of multi-stage telescopic rods 12 corresponds to the number of elastic elements. The two ends of the multi-stage telescopic rods 12 are connected to the mating grooves 9 and the movable plates 8. The first elastic elements 11 are sleeved on the outside of the multi-stage telescopic rods 12.

[0027] In an optional embodiment, driven gears 13 are connected to both ends of the rotating roller 7, and a drive gear ring 14 that meshes with the driven gears 13 is connected to the separating cylinder 2. The rotation of the separating cylinder 2 will drive the drive gear ring 14 to rotate and mesh with the driven gears 13, thereby driving the rotating roller 7 to rotate, providing power for the rotation of the rotating roller 7, and preventing the protrusions 10 from getting stuck in the mesh on the separating cylinder 2.

[0028] Example 3

[0029] like Figure 2 , Figure 4 , Figure 5 As shown, this utility model proposes a manufactured sand and gravel separation and cleaning device. Compared with Embodiment 2, this embodiment describes the detailed structure of the separation component. The separation component includes a drive device 15, threaded rods 16, moving blocks 17, a connecting frame 18, and a push plate 19. Two drive devices 15 are arranged in parallel and connected to the frame 1. The drive device 15 is a geared motor. The number of threaded rods 16 corresponds to the number of drive devices 15. One end of the threaded rod 16 is rotatably connected to a bearing on the inner wall of the frame 1, and the other end of the threaded rod 16 is connected to the output end of the drive device 15. The number of moving blocks 17 corresponds to the number of threaded rods 16. The moving blocks 17 are threadedly connected to the threaded rods 16. Both ends of the connecting frame 18 are connected to the moving blocks 17. The connecting frame 18 is U-shaped or inverted n-shaped. The push plate 19 is connected to the connecting frame 18 and has water-permeable holes. The push plate 19 is inclined, and a connecting block with an inclined surface is connected to the side of the push plate 19 near the connecting frame 18.

[0030] In an optional embodiment, multiple cleaning brushes 20 are connected to both ends of the movable block 17; each cleaning brush 20 consists of a fixed plate 21, a movable plate 22, a brush body 23, and a second elastic member 24. The fixed plate 21 is connected to the movable block 17, the movable plate 8 is arranged parallel to the movable plate 22, the two ends of the second elastic member 24 are connected to the fixed plate 21 and the movable plate 22 respectively, and the brush body 23 is connected to the movable plate 8.

[0031] In summary, when this utility model is used, the sand and gravel to be cleaned enters the feed pipe 3 from the conveyor belt. Then, as the power end on the frame 1 drives the feed pipe 3 to rotate, the sand and gravel gradually enter the separation cylinder 2. The spiral blades inside the separation cylinder 2 gradually transport the sand and gravel closer to the discharge pipe 4. During this process, the sand and gravel come into contact with the water sprayed from the nozzles inside the machine body 1. Through mutual friction, the dust adhering to the surface of the sand and gravel is removed. The cleaned sand and gravel can be gradually discharged out through the discharge pipe 4. Simultaneously, the rotating roller 7 on the separation cylinder 2 is also constantly rotating. The rotation of the drive gear ring 14 on the separation cylinder 2 drives the driven gears 13 at both ends of the rotating roller 7 to rotate, causing the rotating roller 7 to rotate and clean the surface of the sand and gravel. Multiple moving plates 8 take turns contacting the separation cylinder 2. The first elastic element 11 in the groove 9 pushes the moving plates 8 to press tightly against the separation cylinder 2, so that the protrusions 10 on the moving plates 8 are inserted into the mesh on the separation cylinder 2 to transport the blocked mesh. The protrusions 10 prevent the mesh on the separation cylinder 2 from being blocked, thus affecting its efficiency in separating sand and gravel. At the same time, the drive device 15 is started. The output end of the drive device 15 drives the threaded rod 16 to rotate. The moving block 17 on the threaded rod 16 moves linearly along the central axis of the threaded rod 16, which drives the connecting frame 18 and the push plate 19 to move. The push plate 19 pushes the soil separated at the bottom of the frame 1 to be discharged from the discharge port 6, while the sewage containing the remaining mud and sand is discharged from the water outlet 5.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
