[0033] The discharging unit is arranged in the pulverizing chamber; it includes a cover tube 12, an annular screen 15 and a cleaning mechanism 10; one end of the cover tube 12 is provided with an opening, the open end is sleeved on the outside of the grinding roller 13 and is fixedly connected to the pulverizing bin 6; the inner diameter of the cover tube 12 is larger than the outer diameter of the grinding roller 13, and a discharging cavity 11 is arranged between the cover tube 12 and the grinding roller 13 to ensure that there is enough space for the crushed material to pass through; one end of the annular screen 15 is sleeved and fixed to the end of the grinding roller 13 away from the driving motor 1, and the other end is fixedly connected to the cover tube 12; the diameter of the annular screen 15 gradually decreases from one end close to the grinding roller 13 to the other end; the inner diameter of the grinding roller 13 gradually increases from one end close to the driving motor 1 to the other end, and this design helps the material to be evenly distributed on the screen and discharged smoothly; one end of the cleaning mechanism 10 is fixedly connected to the grinding disc 14, and rotates synchronously with the grinding disc 14, and the other end is in friction contact with the inner side of the annular screen 15, and the friction force generated by the rotation cleans the material on the screen to prevent blockage and ensure smooth discharging.

[0034] In this embodiment, in order to more effectively prevent the annular screen 15 from being blocked, a plurality of cleaning mechanisms 10 are configured; the plurality of cleaning mechanisms 10 are distributed in a circular array with the axis of the grinding roller 13 as the center, ensuring that each position of the screen can be cleaned evenly, thereby improving the cleaning effect and overall performance.

This design allows the feed hopper 3 to swing up and down around the hinge point, thereby changing the opening angle and size of the feed port to meet the needs of different materials and feeding speeds. At the same time, the hydraulic push rod 2 provides stable support and adjustment force to ensure the stability and reliability of the feed hopper 3 during the swinging process.

[0038] Working principle:

[0039] The material enters the pulverizing chamber through the feed hopper 3 and is crushed by the shear force between the rotating grinding disc 14 and the grinding roller 13. The crushed material slides along the inner side of the grinding roller 13 toward the annular screen 15, and the fine particles pass through the screen into the discharge chamber 11 and are finally discharged from the device. At the same time, the cleaning mechanism 10 rotates synchronously with the grinding disc 14, continuously cleaning the material on the annular screen 15, effectively preventing the screen from being blocked and improving the pulverizing efficiency.
