The adjusting device includes a toothed ring 13, with multiple curved rods 12 arranged in a ring array inside the toothed ring 13. The other end of each curved rod 12 is movably connected to one end of the outer side of the lower baffle 11. The gear ring 13 is connected to a gear 14 on its outer side. A motor 15 is installed at the bottom of the gear 14. The motor 15 drives the gear 14 to rotate, which causes the gear ring 13 to move the crank 12 and adjust the position of the lower baffle 11. The two sides and the outer side of the lower baffle 11 are all arc-shaped. One side of the lower baffle 11 is a concave arc-shaped arc, and the other side of the lower baffle 11 is a convex arc-shaped arc. The concave side of one lower baffle 11 fits against the convex side of an adjacent lower baffle 11 on one side, and the convex side of the lower baffle 11 fits against the concave side of an adjacent lower baffle 11 on the other side. Multiple lower baffles 11 are combined to form a complete circle.
[0025] Specifically, the upper end of the machine body 1 is provided with a feed inlet 2, the lower end of the machine body 1 is provided with a discharge pipe 6, the discharge pipe 6 is covered with an outer cover 16, the outer cover 16 is installed at the bottom of the machine body 1 by screws, the adjustment device is set in the outer cover 16, the upper baffle 3 is hinged to the feed inlet 2, the hydraulic rod 4 is rotatably installed between the upper baffle 3 and the upper end face of the machine body 1, and a filter screen 5 is installed on the upper baffle 3 for filtering dust.
[0026] In this embodiment, the machine body 1 and the discharge pipe 6 are an integral structure. The two sides of the feed inlet 2 are inclined from top to bottom. The upper baffle 3 is also inclined and fits against the feed inlet 2. The hydraulic rod 4 operates to adjust the opening angle of the upper baffle 3 by pulling or pushing it so that the material can enter the machine body 1. After entering the machine body 1, the upper baffle 3 is pushed to reset and close the feed inlet 2, so that the dust generated during the crushing process is filtered by the filter screen 5 and discharged.
[0027] Specifically, the lower end of the discharge pipe 6 is provided with two symmetrically arranged connecting rings 7. The upper connecting ring 7 is installed at the lower end of the discharge pipe 6 with screws, and the lower connecting ring 7 is connected to the discharge pipe 9 with screws, the discharge pipe 9 passing through the outer cover 16; between the upper and lower connecting rings 7, there are fixed posts 10 adapted to the lower baffle 11 in a circular array, the fixed posts 10 vertically passing through the outer side of the lower baffle 11 near the concave side; inside the connecting rings 7, scraper rings 8 are installed with screws, the upper and lower scraper rings 8 are symmetrically arranged, and the scraper rings 8 are made of metal. The material is in contact with the upper and lower surfaces of the lower baffle 11. It is used to adjust the time of the lower baffle 11. If it is adjusted externally, it will push the broken material accumulated on the lower baffle 11 to fall down, so as to avoid carrying it into the outer cover 16 and causing waste. The other end of the outer side of the lower baffle 11 is rotatably connected to one end of the crank 12. The other end of the crank 12 is rotatably connected to the inner side of the gear ring 13.

The gear 14 meshes with the outer edge of the gear ring 13, causing the gear ring 13 to rotate and push or pull the lower baffle 11, thereby adjusting the size of the upper and lower openings of the feeding pipe 9 and adjusting the feeding amount.
[0029] The working principle and usage process of this utility model are as follows: During use, the material enters the machine body 1 through the feed inlet 2. After one batch of material is finished, the external control device (external drive device, which is electrically connected to the hydraulic rod 4 of the motor 15) controls the operation of the hydraulic rod 4. By pushing the upper baffle 3, its opening angle is adjusted, and the feed inlet 2 is closed, so that the dust generated during the crushing process is filtered through the filter screen 5 and discharged. During this process, the crushed material falls into the discharge pipe 6. The external control device controls the operation of the motor 15, which drives the gear 14 to rotate. The gear 14 meshes with the outer edge of the gear ring 13, so that the gear ring 13 rotates to push or pull the lower baffle 11, thereby adjusting the size of the upper and lower feed openings of the discharge pipe 9 and adjusting the amount of material discharged.
