DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4, the present utility model provides a technical solution: a construction waste crushing device, including a crushing box 1. Symmetric first chutes 2 are opened at a position near the top end of the crushing box 1. Symmetric second chutes 3 are opened at a position near the bottom end of the first chute 2. First baffles 4 are slidably connected in the first chutes 2 respectively. Second baffles 5 are slidably connected in the second chutes 3 respectively. One side of each of the first baffle 4 and the second baffle 5 is fixedly connected with an extrusion shaft 6. One side of the inner bottom end of the crushing box 1 is fixedly installed with a first motor 7. The output end of the first motor 7 is fixedly connected with a lead screw 8. A threaded block 9 is threadedly connected to the lead screw 8. Both ends of the threaded block 9 are hinged with transmission rods 10. The ends of the transmission rods 10 far from the threaded block 9 are respectively hinged with racks 11. One side of the rack 11 is fixedly connected with a slider 12. The crushing box 1 is provided with a limiting groove 13 corresponding to the slider 12. The crushing box 1 is rotatably connected with a round shaft 14 at a position corresponding to the middle of the first chute 2 and the second chute 3. A first gear 15 is fixedly connected to the middle position of the round shaft 14. An extrusion plate 16 is fixedly connected to the side of the round shaft 14 close to the first gear 15.

[0018] The middle position of the crushing box 1 is rotatably connected with symmetrically arranged crushing rollers 17. A second gear 18 is fixedly connected to one side of each of the crushing rollers 17, and the two second gears 18 are meshed. One side of the crushing box 1 is fixedly installed with a second motor 19, and the output end of the second motor 19 is fixedly connected with one of the crushing rollers 17, which is convenient for the second motor 19 to drive the two crushing rollers 17 to extrude the material. Symmetric extrusion grooves are opened on the extrusion plate 16, and the extrusion grooves are arranged corresponding to the extrusion shafts 6, which is convenient for the extrusion plate 16 to extrude the extrusion shafts 6. The limiting groove 13 and the slider 12 are designed with a T-shaped structure, and the slider 12 is slidably connected with the limiting groove 13, which is convenient for the limiting groove 13 to limit the slider 12. The slider 12 is used to limit the rack 11. The first gear 15 is arranged corresponding to the rack 11, and the first gear 15 is meshed with the rack 11, which is convenient for the rack 11 to perform extrusion transmission on the gear 15.

[0019] Specifically, when using the present utility model, the second motor 19 is started. The output end of the second motor 19 drives one of the crushing rollers 17 to rotate. The rotating crushing roller 17 drives the other crushing roller 17 to rotate through the second gear 18. The mutually rotating crushing rollers 17 can crush the garbage. At the same time, the first motor 7 is started. The output end of the first motor 7 drives the lead screw 8 to rotate. The lead screw 8 drives the threaded block 9 to rotate. The threaded block 9 pulls the two hinged transmission rods 10. The pulled transmission rods 10 pull and drive the rack 11. The pulled rack 11 approaches each other along the limiting groove 13 through the slider 12. The mutually approaching racks 11 squeeze the first gear 15. The squeezed first gear 15 drives the round shaft 14 to rotate. The round shaft 14 drives the pressing plate 16 to rotate. The rotating pressing plate 16 simultaneously presses the pressing shafts 6 on the first baffle 4 and the second baffle 5. The first baffle 4 being pressed moves away from each other along the first sliding groove 2. The second baffle 5 being pressed approaches each other along the second sliding groove 3. At this time, the construction waste is poured onto the top of the second baffle 5. The first motor 7 is started again. The first motor 7 drives the first baffle 4 to approach each other and at the same time drives the second baffle 5 to move away from each other. The garbage that loses the support of the second baffle 5 falls onto the top of the crushing roller 17 for crushing. The mutually approaching first baffles 4 block the top of the crushing roller 17, preventing the escape of dust and splashes.

[0020] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
