The turbine 6 is fixedly mounted on the rotating shaft 4. The rotating shaft 4 is vertically rotatably connected to the outside of the box body 2. A toggle gear 7 arranged below the turbine 6 is fixedly mounted on the rotating shaft 4.

[0017] A discharge hole 24 is opened on the left side wall of the box body 2, and a sieve plate 8 is arranged in the box body 2. The sieve plate 8 is located below the crushing roller 1. The left end of the sieve plate 8 extends into the discharge hole 24 and is in sliding contact with the bottom surface of the discharge hole 24. The right end of the sieve plate 8 movably passes through the box body 2 and is fixedly connected with a paddle 9. The height of the paddle 9 is equal to the thickness of the sieve plate 8. The right end of the paddle 9 extends between any two adjacent teeth of the toggle gear 7. The right end of the bottom surface of the sieve plate 8 is fixedly connected with a vertical plate 10. The vertical plate 10 is located between the box body 2 and the rotating shaft 4. A spring 11 is arranged between the vertical plate 10 and the right side plate of the box body 2.

[0018] A scraper assembly is provided on the upper side of the sieve plate 8, and the scraper assembly includes a scraper 12, a pull rod 14 and a baffle 13. The scraper 12 is vertically arranged between the sieve plate 8 and the crushing roller 1, and is in sliding contact with the top surface of the sieve plate 8. The top surface of the scraper 12 is lower on the left and higher on the right. The front and rear side surfaces of the scraper 12 are in sliding contact with the front and rear inner walls of the box 2. The left side of the scraper 12 is fixedly connected to the pull rod 14, and the left end of the pull rod 14 passes through the discharge hole 24 and is fixedly connected to the baffle 13. When the baffle 13 is located in the discharge hole 24, the discharge hole 24 is closed, and the scraper 12 is in contact with the right inner wall of the box 2.

[0019] The box body 2 is fixed on a base 25 , a transverse plate 3 is provided at the upper end of the right outer wall of the box body 2 , and the upper and lower ends of the rotating shaft 4 are rotatably connected to the transverse plate 3 and the base 25 , respectively.

[0020] A bolt 16 is fixed to the left outer wall of the box body 2 , and a limiting plate 15 is provided on the upper end of the left side surface of the baffle 13 . The bolt 16 passes through the limiting plate 15 and is limited by a nut 17 .

[0021] The two ends of each crushing roller 1 are respectively connected to the left and right side plates of the box body 2 through the rotating rod 18 and the rotating rod 2 19, that is, the left ends of the front crushing roller 1 and the rear crushing roller 1 are connected to the left side plate of the box body 2 through the rotating rod 18, and the right ends of the front crushing roller 1 and the rear crushing roller 1 are connected to the right side plate of the box body 2 through the rotating rod 2 19. The left end of the rotating rod 18 on each crushing roller 1 is fixedly connected to the driving gear 20 located on the outside of the box body 2. The two driving gears 20 are provided with a cover body 21 fixed on the side wall of the box body 2 outside. The two driving gears 20 are meshed with each other. A motor 22 is fixedly installed on the cover body 21. The output shaft of the motor 22 movably passes through the cover body 21 to connect to any left end of the rotating rod 18. The right end of the front crushing roller 1 is fixedly connected to the worm 5 through the rotating rod 2 19. The motor 22 drives any crushing roller 1 to rotate.

[0022] A discharge door 23 is provided at the lower portion of the front side wall of the box body 2 , and the top of the discharge door 23 is not higher than the sieve plate 8 .

[0025] When in use, the motor 22 is started to drive the crushing roller 1 to operate, and bauxite and other materials are fed in through the opening above the box body 2. After being crushed, the materials fall into the screen plate 8. At this time, the rotating rod 2 19 at the right end of the front crushing roller 1 drives the worm 5 to rotate as the crushing roller 1 operates, and at the same time, the turbine 6 meshing with the worm 5 rotates. When the turbine 6 rotates, the toggle gear 7 is driven to rotate through the rotating shaft 4. When the toggle gear 7 rotates, the rotation direction is toward the inclined surface of the paddle, thereby intermittently toggling the paddle 9 to push The sieve plate 8 is then fixedly connected to the vertical plate 10 and the spring 11 at the right end of the bottom surface of the sieve plate 8. Under the action of the elastic force of the spring 11, the sieve plate 8 that has been pushed rebounds and resets. This reciprocating cycle allows the smaller materials to fall to the bottom of the box body 2 after being crushed, and the larger materials remain on the sieve plate. When a large amount of larger materials accumulate, the nut 17 is unscrewed to release the sealing of the baffle plate 13 on the discharge hole 24, and the pull rod 14 is pulled to push the larger materials accumulated above the sieve plate 8 into the storage box 26 through the scraper 12.
