The waste collection device 1 and the discharge device 2 are sealed together. The waste collection device 1 can suck all the waste into a collection box 11, and the waste passes through the collection box 11 and falls into the discharge device 2. After being screened by the screening mechanism 3, the waste is collected separately. The sealed connection between the waste collection device 1 and the discharge device 2 can reduce the problem of dust splashing.

[0034] In this embodiment, specifically, the screening mechanism 3 is a screen 31, which has a good screening effect.

[0035] In this embodiment, the waste collection device 1 includes a collection box 11, a suction head 12, an absorption pipe 13, and a suction fan 14. The collection box 11 is hollow inside, one end of the absorption pipe 13 is connected to the inside of the collection box 11, and the other end is connected to the suction head 12. The suction fan 14 is assembled on the outer wall of the collection box 11, and a filter plate 15 is provided at the suction port of the suction fan 14. The suction fan 14 can suck the waste into the collection box 11, and the filter plate 15 is provided to prevent the waste from entering the suction fan 14, so that the waste only stays in the collection box 11. It should be noted that the absorption pipe 13 adopts a telescopic hose, which is convenient for adjusting the telescopic angle to achieve waste collection.

[0036] In this embodiment, the unloading device 2 includes a unloading box 21, a first unloading port 22, and a second unloading port 23. The unloading box 21 is hollow inside, and the bottom surface of the unloading box 21 is tilted to facilitate waste materials with a particle size smaller than the screen 31 to flow out of the screen 31 and out of the second unloading port 23 through the unloading box 21 with an inclined bottom surface. The top of the unloading box 21 is sealed with the bottom of the collecting box 11. The first unloading port 22 is provided on one side above the screening mechanism 3 in the unloading box 21, and the second unloading port 23 is provided on one side below the screening mechanism 3 in the unloading box 21. Wastes of different particle sizes are collected separately through the first unloading port 22 and the second unloading port 23. In this embodiment, the first unloading port 22 and the second unloading port 23 are also tilted.

[0037] In this embodiment, a support structure 4 is also included. The support structure 4 is assembled below the blanking box 21. The support structure 4 includes a plurality of first support rods 41, a plurality of second support rods 42, and a vibration spring 43. Specifically, in this embodiment, the number of the first support rods 41 and the second support rods 42 is four.

The output end of the hydraulic cylinder 61 is fixedly connected to the push plate 62. The hydraulic cylinder 61 and the push plate 62 can push the waste material on the top of the screen 31 that has not passed through the screen 31 to the first discharge port 22. The bottom surface of the push plate 62 is bonded with wear-resistant rubber 63 to improve the durability of the push plate 62.

[0039] The working principle and steps of the present invention are as follows: when in use, the suction fan 14 is started to make the suction head 12 generate suction to absorb the waste. The absorbed waste enters the collection box 11 through the absorption pipe 13, is blocked by the filter plate 15 so that the waste remains in the collection box 11, and then falls into the discharge box 21. After passing through the screening mechanism 3, the vibration motor 5 is turned on and vibrates with the vibration spring 43. Waste with a particle size smaller than the screen 31 will pass through the screen 31 and be discharged from the second discharge port 23. Waste with a particle size larger than the screen 31 will stay above the screen 31. The hydraulic cylinder 61 is started and the waste above the screen 31 is pushed to the first discharge port 22 for discharge through the push plate. The collection of polyester resin powders of different particle sizes is completed.
