The bottom of the support rod 14 is equipped with a collecting mechanism 2, which is used to collect the crushed plastic woven bags. The left side of the feeding pipe 7 is engaged with a protective cylinder 6, and the middle part of the left side of the protective cylinder 6 is fixedly connected with a rotating handle 8. The protective cylinder 6 can be opened and closed by rotating the handle 8. The top of the trapezoidal box 15 is rotatably connected with a rotating rod 26, and the front side of the rotating rod 26 is fixedly connected with an opening and closing plate 5. The top front side of the opening and closing plate 5 is fixedly connected with a first handle 4. The opening and closing plate 5 can be opened and closed by installing the first handle 4.
[0033] Specifically, in the process of transporting the plastic woven bag to the trapezoidal box 15, the first motor 17 is started, which will drive the connecting rod 19 to rotate. Subsequently, the two rotating blades 18 will rotate rapidly with the rotation of the connecting rod 19. At the same time, the driving gear 20 fixedly connected to the right side of the connecting rod 19 will also start to rotate and engage with the driven gear 16 for transmission, thereby driving the pushing rod 21 to rotate counterclockwise, so that the woven bag is pushed inward at a uniform speed, and the rotating blade 18 will perform the cutting operation.

[0038] Working principle: transport the plastic woven bag into the trapezoidal box 15, turn on the first motor 17, so that the connecting rod 19 rotates, and the two rotating blades 18 will rotate rapidly, and the driving gear 20 fixedly connected to the right side of the connecting rod 19 will rotate and mesh with the driven gear 16 for transmission, thereby rotating the push rod 21, and the rotation direction is counterclockwise, so that the transported woven bag can be pushed inward at a uniform speed, and the rotating blade 18 will cut it, and then transport it into the crusher 1 through the protective cylinder 6 for crushing. When the work is completed, the opening and closing plate 5 is pulled by the first handle 4 to rotate, and the trapezoidal box 15 is closed to prevent dirt from entering. Through the above process, the staff does not need to manually cut the woven bags, which improves work efficiency and saves human resources.
[0039] When crushing begins, first place the collecting bucket 201 and the fixed bucket 205 at the bottom of the crusher 1, then the crusher 1 is put into operation, the crushed woven bags will fall into the collecting bucket 201, turn on the second motor 206, the stirring rod 203 will rotate and stir the materials to make them evenly mixed, and open the discharge plate 202 through the second handle 12. Since the scraper 204 also rotates and scrapes the materials on the inner wall of the collecting bucket 201, the materials will be transported out through the discharge plate 202, thereby improving the collection efficiency.
