[0025] The rolling and filtering mechanism 28 includes a filter screen 29, a first rolling roller 30 and a second rolling roller 32. A support plate 37 is symmetrically provided at the top of the filter screen 29. The first rolling roller 30 and the second rolling roller 32 are respectively arranged at the top of the support plate 37.

The third sprocket 34 drives the fourth sprocket 36 to rotate through the second chain 35, thereby driving the second laminating roller 32 to rotate.

[0027] An arc-shaped protective cover 15 is symmetrically fixedly installed on the inner side of the separation chamber 2, and a first nozzle 18 is evenly fixedly installed on the first branch pipe 17. The first branch pipe 17 and the first nozzle 18 are both located on the inner side of the arc-shaped protective cover 15. A guide ramp 22 is provided at the bottom end of the discharge chamber 3, and the guide ramp 22 is inclined.

[0028] The first rolling roller 30 and the second rolling roller 32 are respectively rotatably mounted on the flushing and separation box 1 through a rotating shaft, and the second nozzle 21 is evenly fixedly mounted on the second branch pipe 20. The two second branch pipes 20 are respectively located at the top of the first rolling roller 30 and the second rolling roller 32. The support block 38 is fixedly mounted on the inner wall of the separation chamber 2. The filter screen 29 is inclined in design. A guide plate 43 is fixedly mounted on the downwardly inclined end of the filter screen 29. A debris discharge hopper 14 is fixedly mounted on the end of the flushing and separation box 1 close to the guide plate 43. The debris discharge hopper 14 is located below the guide plate 43. The stones filtered out by the filter screen 29 flow into the interior of the debris discharge hopper 14 through the guide plate 43 and are discharged.

[0029] The upwardly inclined end of the filter screen 29 is located below the downwardly inclined end of the guide ramp 22. The inner side of the separation chamber 2 is fixedly connected to the upwardly inclined end of the filter screen 29 with a guide plate 31. The guide plate 31 is located above the filter screen 29. The muddy water inside the discharge chamber 3 is guided to the top of the guide plate 31 through the guide ramp 22, and then guided to the top of the filter screen 29 through the guide plate 31 for filtration.

[0030] The bottom end of the flushing and separation box 1 is fixedly connected to a discharge pipe 12, and the side of the discharge pipe 12 is fixedly connected to a discharge branch pipe 13. The bottom end of the flushing and separation box 1 is fixedly installed with a bottom support frame 5, and a first high-pressure pump 7 is fixedly installed on the bottom support frame 5. The input end of the first high-pressure pump 7 is fixedly installed on the discharge branch pipe 13, and a hydrocyclone 4 is fixedly installed on the bottom support frame 5. The hydrocyclone 4 includes a tangential feed pipe 10, a top overflow pipe 11 and a bottom discharge port. The hydrocyclone 4 is fixedly installed at the output end of the first high-pressure pump 7 through the tangential feed pipe 10. The first high-pressure pump 7 flushes the internal mixed fluid of the separation box 1 through the discharge branch pipe 13. The muddy water containing crushed small sand and gravel is extracted and then transported to the top of the hydrocyclone 4 through the tangential feed pipe 10. Since the tangential feed pipe 10 is located on one side of the hydrocyclone 4, the muddy water entering the hydrocyclone 4 through the tangential feed pipe 10 rotates around the inside of the hydrocyclone 4. The muddy water containing stone is injected into the cylindrical section at the top of the hydrocyclone 4 at high speed from the tangential feed pipe 10, forming a spiral rotating flow field. Because the stone has a greater density than the muddy water, it is thrown toward the wall of the hydrocyclone under the action of centrifugal force and discharged from the bottom discharge port with the outer layer downward flow, while the low-density fluid such as muddy water gathers toward the center and is discharged from the top overflow pipe 11 with the inner layer upward flow.

[0031] Working principle: During use, first connect the top overflow pipe 11 to the mud and water collection tank, and connect the input end of the second high-pressure pump 8 to the water source and turn on the servo motor 6 and the second high-pressure pump 8. The second high-pressure pump 8 transports water to the first guide pipe 16 and the second guide pipe 19 through the Y-shaped water distribution pipe 9. The first guide pipe 16 sprays water into the discharge chamber 3 through the first branch pipe 17 and the first nozzle 18. The second guide pipe 19 sprays water on the top of the first rolling roller 30 and the second rolling roller 32 in the separation chamber 2 through the second branch pipe 20 and the second nozzle 21. Then, the crushed materials screened out from the construction waste are transported to the inside of the discharge chamber 3 through the conveyor belt. After the crushed materials enter the inside of the discharge chamber 3, they are sprayed by the water flow sprayed by the first nozzle 18. The muddy water is mixed and dispersed to form muddy water. The started servo motor 6 drives the first rolling roller 30 to rotate. The rotation of the first rolling roller 30 drives the first sprocket 25 and the third sprocket 34 to rotate synchronously. The first sprocket 25 drives the second sprocket 27 to rotate through the first chain 26, thereby driving the rotating roller 23 and the stirring rod 24 to rotate. The third sprocket 34 drives the fourth sprocket 36 to rotate through the second chain 35, thereby driving the second rolling roller 32 to rotate. When the muddy water passes through the rotating roller 23, it is stirred by the rotating stirring rod 24 and evenly discharged to the guide plate 31 through the guide inclined plate 22. Under the diversion effect of the guide plate 31, the muddy water is discharged to the top of the filter screen 29. When the muddy water flows to the first rolling roller 30, the rotating first rolling roller 30 rolls the muddy water through the rolling teeth 33. The soil blocks are crushed and fully mixed with water by the rolling of the rolling teeth 33. When encountering stones, the rolling teeth 33 bite into the top of the stone and squeeze the stone downward as the rolling teeth 33 rotates. The stone squeezes the support plate 37. The support plate 37 is squeezed to drive the top of the filter screen 29 to rotate downward and push the sliding support rod 39 to move downward on the inner side of the limiting sliding hole 42, while squeezing the energy storage spring 40 to contract. When the stone is pushed to the other side by the rolling teeth 33 and passes through the bottom end of the first rolling roller 30, the energy storage spring 40 rebounds and pushes the filter screen 29 to rotate upward until it returns to its initial position. In the process of the energy storage spring 40 pushing the filter screen 29 to rotate upward, the filter screen 29 vibrates due to the continuous contraction and rebound characteristics of the energy storage spring 40, thereby accelerating the mud. The water is filtered and the water flow sprayed on the outer side of the rolling teeth 33 by the second nozzle 21 impacts the rolling teeth 33, thereby washing away the mud adhered to the rolling teeth 33 and at the same time washing the filter screen 29, reducing the probability of blockage of the filter screen 29. When the stone moves to the second rolling roller 32, the stone is pushed to the other side in the same way as the first rolling roller 30, until the stone moves to the guide plate 43 and is discharged to the stone accumulation place through the debris discharge hopper 14. Then the first high-pressure pump 7 is started, and the first high-pressure pump 7 pumps out the muddy water mixed with crushed small sand and gravel inside the washing separation box 1 through the discharge branch pipe 13, and then transports it to the inner top of the hydrocyclone 4 through the tangential feed pipe 10. Since the tangential feed pipe 10 is located on one side of the hydrocyclone 4,Therefore, the muddy water that enters the hydrocyclone 4 through the tangential feed pipe 10 rotates around the inside of the hydrocyclone 4. The muddy water containing stone is ejected from the tangential feed pipe 10 at high speed into the cylindrical section at the top of the hydrocyclone 4, forming a spiral rotating flow field. Because the stone has a higher density than the muddy water, it is thrown toward the wall under the action of centrifugal force and discharged from the bottom discharge port with the outer layer downward flow. The low-density fluid such as muddy water gathers toward the center and is discharged from the top overflow pipe 11 with the inner layer upward flow and transported to the muddy water collection box, thus achieving secondary separation of stone and muddy water.
