Detailed Implementation

[0015] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0016] A portable rapid sorting device for recycled aggregates from construction waste includes a box 1. A servo motor 2 and a water tank 3 are fixedly connected to the top of the box 1. A hopper 4 is connected to the top of the box 1. The output end of the servo motor 2 passes through the box 1 and is rotatably connected to it. A drive assembly is provided at the output end of the servo motor 2. A spray assembly is provided at the top inside the box 1. A pair of support blocks 5 are fixedly connected to the inner walls on both sides of the box 1. A guide rod 6 is fixedly connected between the pair of support blocks 5. A slider 7 is slidably connected to the guide rod 6. A first fixed plate 8 is fixedly connected to one side of the slider 7. A first screen plate 9 is fixedly connected to the top of the first fixed plate 8. A second screen plate 10 is fixedly connected to the bottom of the first fixed plate 8. A funnel 11 is fixedly connected between the pair of first fixed plates 8. A second fixed plate 12 is fixedly connected between the second screen plate 10 and the first screen plate 9. One side of the second fixed plate 12 is fixedly connected to the funnel 11. A first push-pull rod 13 is fixedly connected to the other side of the second fixed plate 12. A first transmission block 14 is fixedly connected to one end of the first push-pull rod 13. Specifically, the bottom of the box 1 is connected to a discharge port, which is funnel-shaped. When the servo motor 2 is started, its output drives the drive assembly. The drive assembly drives the first transmission block 14 to move. The first transmission block 14 pushes and pulls the second fixed plate 12 back and forth through the first push-pull rod 13, causing the first screen plate 9 and the second screen plate 10 to vibrate back and forth. The first screen plate 9 and the second screen plate 10 drive the first fixed plate 8 to move. The first fixed plate 8 drives the slider 7 to slide back and forth along the guide rod 6. At the same time, the drive assembly drives the spraying assembly to work, spraying the water stored in the water tank 3 and adding aggregate into the box 1 through the hopper 4. The spray assembly sprays the aggregate entering the box 1, which not only prevents dust from spreading during screening, but also performs preliminary cleaning of the aggregate. Combined with vibrating screening, it removes impurities such as mud attached to the surface of the aggregate, improving the cleanliness of the aggregate. The aggregate first falls onto the first screen plate 9 for primary screening. The funnel 11 can collect the product screened by the first screen plate 9 and let it fall onto the screen of the second screen plate 10 away from the outlet for secondary screening. This extends the movement path and screening time of the aggregate on the second screen plate 10, reducing missed screening. The product screened by the second screen plate 10 is mixed with wastewater and falls through the discharge port at the bottom of the box 1.

[0017] The drive assembly includes an upper turntable 15, which is coaxially fixedly connected to the output end of the servo motor 2. A drive shaft 16 is fixedly connected to the bottom of the upper turntable 15 at an off-center position. A lower turntable 17 is fixedly connected to the bottom of the drive shaft 16. A rotating shaft is coaxially fixedly connected to the bottom of the lower turntable 17. The bottom of the rotating shaft is rotatably connected to the housing 1. Specifically, the axes of the upper turntable 15 and the lower turntable 17 are on the same vertical line. The output of the servo motor 2 drives the upper turntable 15 to rotate, the upper turntable 15 drives the transmission shaft 16 to perform circular motion, and the transmission shaft 16 drives the lower turntable 17 to rotate.

[0018] The spray assembly includes a cylinder 18, which is fixedly connected to the top of the housing 1. A second push-pull rod 19 is slidably connected to the cylinder 18. A piston plate 20 is fixedly connected to one end of the second push-pull rod 19 and slidably connected to the cylinder 18. A second transmission block 21 is fixedly connected to the other end of the second push-pull rod 19. An inlet 22 and an outlet 23 are respectively connected to one side of the cylinder 18. A one-way valve is provided on both the inlet 22 and the outlet 23. A three-way connector 24 is connected to one end of the outlet 23. A conduit 25 is connected to the output end of the three-way connector 24. Multiple nozzles are connected to the conduit 25. One end of the conduit 25 is fixedly connected to the side wall of the housing 1. The inlet 22 and the water tank 3 are connected through a hose. Specifically, the one-way valve on the inlet 22 allows water to flow into the cylinder 18 from the inlet 22, and the one-way valve on the outlet 23 allows water to flow out of the cylinder 18 through the outlet 23. The drive assembly drives the second transmission block 21 to reciprocate. The second transmission block 21 drives the piston plate 20 to reciprocate and slide within the cylinder 18 through the second push-pull rod 19, so that the water in the water tank 3 enters the cylinder 18 through the hose and the inlet 22 in sequence, and then enters the conduit 25 through the outlet 23 and the three-way connector 24 in sequence, and finally sprays out through the nozzle.

[0019] Both the first transmission block 14 and the second transmission block 21 are provided with waist-shaped grooves, which are adapted to the transmission shaft 16. Specifically, the drive shaft 16 drives the first drive block 14 and the second drive block 21 to move together through the waist-shaped groove.

[0020] A pair of support columns are fixedly connected to both sides of the box body 1; Specifically, the support columns are used to support and stabilize the box 1, and a pair of support columns are fixed together by crossbars.

[0021] The implementation principle of this application is as follows: Start the servo motor 2. The output of the servo motor 2 drives the upper turntable 15 to rotate. The upper turntable 15 drives the transmission shaft 16 to perform a circular motion. The transmission shaft 16 drives the lower turntable 17 to rotate. The transmission shaft 16 drives the first transmission block 14 and the second transmission block 21 to move together through the waist-shaped groove. The first transmission block 14 pushes and pulls the second fixed plate 12 back and forth through the first push-pull rod 13, causing the first screen plate 9 and the second screen plate 10 to vibrate back and forth. The first screen plate 9 and the second screen plate 10 drive the first fixed plate 8 to move. The first fixed plate 8 drives the slider 7 to slide back and forth along the guide rod 6. The second transmission block 21 also reciprocates. The second transmission block 21 drives the piston plate 20 to reciprocate and slide within the cylinder 18 via the second push-pull rod 19, so that the water in the water tank 3 enters the cylinder 18 through the hose and the inlet 22 in sequence, then enters the pipe 25 through the outlet 23 and the three-way connector 24 in sequence, and finally sprays out through the nozzle. Aggregates are added into the housing 1 through the hopper 4. The spray assembly sprays the aggregates entering the housing 1, which not only prevents dust from spreading during screening, but also performs preliminary cleaning of the aggregates. Combined with vibrating screening, it removes impurities such as mud attached to the surface of the aggregates, improving the cleanliness of the aggregates. The aggregates first fall onto the first screen plate 9 for primary screening. The funnel 11 can collect the product screened by the first screen plate 9 and let it fall onto the screen of the second screen plate 10 away from the outlet for secondary screening. This extends the movement path and screening time of the aggregates on the second screen plate 10, reducing missed screening. The product screened by the second screen plate 10 is mixed with wastewater and falls through the discharge port at the bottom of the housing 1.
