[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-4 As shown, this utility model provides a technical solution: an elastic polyurethane recycling crusher, including a mounting frame 1 and a square plate 32. A crushing box 2 is fixedly connected to the center of the mounting frame 1. A spiral crushing blade 22 is rotatably connected to the inside of the crushing box 2 near its center. An inlet 21 is opened at the center of the top of the crushing box 2, and an outlet 3 is opened at the side end of the crushing box 2. Two sets of support shafts 31 are symmetrically fixedly connected to the side end of the crushing box 2 near the outlet 3. External threads 34 are opened on the outer ring of the support shafts 31 near one side. Circular holes 35 are opened inside the square plate 32 near the corners, and the circular holes 35 are connected to the support shafts 31. The square plate 32 is fitted with a screen plate 33 fixedly connected to the center. When the material is put into the crushing box 2, it is gradually reduced in size by the shearing between the spiral crushing blade 22 and the fixed blade inside the crushing chamber. As the spiral drum rotates, the right end of the spiral crushing blade 22 and the screen plate 33 will eventually form a frictional contact to discharge the material. The size of the discharged particles can be adjusted by replacing the screen plate 33 with different specifications. It should be noted that if the size of the discharged particles becomes smaller, the feeding speed of the raw materials needs to be reduced to avoid excessive filling inside the crushing box 2, which could lead to mechanical failure.

[0021] The mounting bracket 1 is fixedly connected to the base 11 at the side end away from the support shaft 31 and near the center.

[0022] By adopting the above technical solution, a base 11 is set on the side of the mounting frame 1 to support and fix the reducer 13.

[0023] A speed reducer 13 is detachably connected to the top of the base 11. The output end of the speed reducer 13 passes through the crushing box 2 and is fixedly connected to the spiral crusher 22.

[0024] By adopting the above technical solution, the speed reducer 13 can be used to rotate the fixedly connected spiral crusher 22 to complete the crushing of materials.

[0025] A vertical plate 23 is fixedly connected to the top of the crushing box 2 and near the feed inlet 21.

[0026] By adopting the above technical solution, a vertical plate 23 is set at the top of the crushing box 2 to facilitate the sliding installation of the cover plate 28.

[0027] A horizontal groove is provided inside the vertical plate 23 near the center, and a support rod 24 is slidably connected to the vertical plate 23 at the horizontal groove.

[0028] By adopting the above technical solution, a horizontal groove is opened inside the vertical plate 23 to slide the support rod 24 and complete the work of moving the cover plate 28.

[0029] The front end of the vertical plate 23 is symmetrically fixedly connected to the two sides with side plates 25. The two side plates 25 are rotatably connected with a screw rod 26, and the support rod 24 is rotatably connected to the screw rod 26 with a thread.

[0030] By adopting the above technical solution, after the lead screw 26 is rotated, the threaded rotating support rod 24 can move horizontally.

[0031] The bottom end of the support rod 24 is fixedly connected to the inlet 21 at the same level as the feed port 21, and the cover plate 28 is adapted to the feed port 21.

[0032] By adopting the above technical solution, a cover plate 28 is set at the bottom of the support rod 24 in order to close the feed inlet 21.

[0033] A motor 27 is fixedly connected to one end of the side plate 25 away from the lead screw 26, and the output end of the motor 27 passes through the side plate 25 and is fixedly connected to the lead screw 26.

[0034] By adopting the above technical solution, the motor 27 is operated, thereby causing the fixedly connected lead screw 26 to rotate.

[0035] Working principle: When using this device, the material is poured into the crushing box 2 through the feed port 21. Then, the reducer 13 is run to make the spiral crushing blade 22 rotate. The shearing between the spiral crushing blade 22 and the fixed blade inside the crushing chamber gradually decreases. With the gradual rotation of the spiral drum, the right end of the spiral crushing blade 22 will form a frictional contact with the screen plate 33 to discharge the material. When it is necessary to adjust the size of the discharged particles, the bolts on the four external threads 34 can be rotated to release the limiting work of the square plate 32. Then, different models of screen plates 33 and square plates 32 are slidably inserted between the four support shafts 31 and the bolts are used to realize the convenient replacement of different models of screen plates 33.

[0036] After the material is fed into the crushing box 2 through the feed inlet 21, the motor 27 needs to be started to rotate the fixedly connected screw 26. With the horizontal movement of the threaded rotating support rod 24, the fixedly connected cover plate 28 can be moved laterally. After the cover plate 28 moves above the feed inlet 21, the feed inlet 21 can be sealed, thus preventing the material from jumping out through the feed inlet 21 during use.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
