At this time, the stirring blade can be driven to rotate clockwise synchronously. Then when the stirring blade rotates, the stirring blade will contact the inclined surface of the triangular block. When the stirring blade continues to rotate, the triangular block will descend, and then the bottom plate will descend. At this time, a part of the raw materials inside the processing box will flow out through the bottom plate.

[0017] 2. When the raw materials inside the processing box flow out along the inclined part of the bottom plate surface, they will fall on the surface of the screening plate. At this time, the sand and stones smaller than the raw materials and the heavier dust will flow through the filtration of the screening plate onto the surface of the discharge plate and then flow out of the device. If the sand and stones happen to be in the gaps of the holes on the surface of the screening plate, the power switch of the electric push rod can be activated at this time to make the output rotating shaft of the electric push rod work. First, shorten the stroke of the output end of the electric push rod. When the electric push rod works, the rotating wheel will move up and down. When the rotating wheel rises, a part of the screening plate rotatably connected inside the fixed box will be tilted. When the rotating wheel descends, under the acting force of the deformation of the first elastic steel ring, the screening plate will automatically reset. After the sundries inside the screening plate are processed, then make the stroke of the electric push rod longer, and then push the screening plate to be tilted. At this time, the raw materials on the surface of the screening plate will flow into the next stage of processing through the feeding plate.
[0018] By setting up the screening component, it can play the role of facilitating the detailed screening of the color-selected raw materials, and further make the overall device have a better effect when processing the color-selected raw materials. Brief Description of the Drawings

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] A multi-layer screening device for a color sorter, including a fixed box 3, a screening component 1, the screening component 1 is installed inside the fixed box 3, and the screening component 1 is used for screening and feeding the raw materials for color sorting. There is a feeding component 2, the feeding component 2 is installed on the upper part of the fixed box 3, and the feeding component 2 is used for preliminary screening and uniform feeding of the raw materials.
[0028] The screening component 1 includes a screening plate 4, the screening plate 4 is rotatably connected inside the fixed box 3, and the rotation connection point of the screening plate 4 is on the right side inside the fixed box 3. Two symmetrically arranged electric push rods 7 are fixedly installed on the bottom wall of the fixed box 3. The top ends of the output shafts of the two electric push rods 7 are both fixedly installed with rotating wheels 8, and the outer surface of the rotating wheel 8 is in contact with the bottom surface of the screening plate 4. An outlet plate 10 is fixedly installed inside the fixed box 3, and two symmetrically arranged first elastic steel rings 11 are fixedly installed between the upper surface of the outlet plate 10 and the bottom surface of the screening plate 4.
[0029] Two guide rails 9 are fixedly installed on the bottom surface of the screening plate 4, and the positions of the two guide rails 9 correspond to the positions of the two rotating wheels 8 respectively, which can make the rotating wheels 8 more stable when jacking up the screening plate 4.
[0030] A feeding plate 12 is fixedly installed on the right side of the inner wall of the fixed box 3 for subsequent feeding of the raw materials.
[0031] The upper surface of the outlet plate 10 is slidably connected to the output end of the electric push rod 7 and the surface of the rotating wheel 8, which can enable the rotating wheel 8 to smoothly perform a lifting movement.
[0032] When it is necessary to feed the raw materials for color sorting, first put the raw materials to be screened into the interior of the processing box 6, then start the power switch electrically connected to the motor body 13 to make the output rotating shaft of the motor body 13 rotate slowly clockwise. At this time, the stirring blades 14 can be driven to rotate clockwise synchronously. Then when the stirring blades 14 rotate, the stirring blades 14 will contact the inclined surface of the triangular block 20. When the stirring blades 14 continue to rotate, the triangular block 20 will descend, thereby causing the bottom plate 15 to descend. At this time, a part of the raw materials inside the processing box 6 will flow out through the bottom plate 15. When one layer of the stirring blades 14 moves away from the upper surface of the triangular block 20, affected by the elastic force generated by the deformation of the second elastic steel ring 19, the bottom plate 15 will automatically rise and reset.
[0033] By setting the feeding component 2, the raw materials inside the fixed box 3 can be stirred to a certain extent by the rotation of the stirring blade 14, and part of the dust can be scraped off the surface of the raw materials, and the raw materials inside the processing box 6 can flow out evenly.
[0034] Embodiment 2
[0035] The feeding component 2 includes a processing box 6. Two fixing frames 5 are fixedly connected to the outer surface of the processing box 6. The other ends of the two fixing frames 5 are fixedly connected to the upper surface of the fixed box 3. A motor body 13 is fixedly installed above the processing box 6. A stirring blade 14 is fixedly connected to the outer surface of the output rotating shaft of the motor body 13. A fixing plate 16 is fixedly connected to the right side of the outer surface of the motor body 13. A bottom plate 15 is placed below the processing box 6. A guiding sleeve 18 is fixedly connected to the upper surface of the bottom plate 15. A guiding plate 17 is fixedly connected to the bottom surface of the fixing plate 16. A second elastic steel ring 19 is fixedly installed between the bottom wall of the guiding plate 17 and the guiding sleeve 18. The guiding plate 17 is clamped with the guiding sleeve 18.

[0036] The cross-sectional shape of the triangular block 20 is triangular, and the rotation direction of the output rotating shaft of the motor body 13 is clockwise rotation, which can smoothly move the bottom plate 15 up and down.
[0037] When the raw materials inside the processing box 6 flow out along the inclined part of the surface of the bottom plate 15, they will fall on the surface of the screening plate 4. At this time, the sand and stones smaller than the raw materials and the heavier dust will flow through the filtration of the screening plate 4 and flow onto the surface of the discharge plate 10, and then flow out of the device. If the sand and stones happen to be in the gaps of the holes on the surface of the screening plate 4, at this time, the power switch of the electric push rod 7 can be turned on to make the output rotating shaft of the electric push rod 7 work. First, the stroke of the output end of the electric push rod 7 becomes shorter. When the electric push rod 7 works, the rotating wheel 8 will move up and down. When the rotating wheel 8 rises, a part of the screening plate 4 rotatably connected inside the fixed box 3 will be inclined. When the rotating wheel 8 descends, under the acting force of the deformation of the first elastic steel ring 11, the screening plate 4 will automatically reset. After the sundries inside the screening plate 4 are processed, then the stroke of the electric push rod 7 is made longer, and then the screening plate 4 is pushed to be inclined. At this time, the raw materials on the surface of the screening plate 4 will flow into the next stage of processing through the feeding plate 12.
[0038] By setting the screening component 1, the effect of facilitating the detailed screening of the color-selected raw materials can be achieved, and further, the overall effect of the device in processing the color-selected raw materials can be better.
