The internal space of the crushing box 1 is divided into three areas. The coal raw materials can be injected into the three areas inside the crushing box 1 through the three feeding ports 2. The rotating motor 6 is started, and the rotating motor 6 drives the horizontal axis 5 to rotate. Since the horizontal axis 5 passes through the first partition plate 3 and the second partition plate 4 through the bearing, the first partition plate 3 and the second partition plate 4 divide the internal space of the crushing box 1 without interfering with the rotation of the horizontal axis 5, which is convenient for crushing the coal raw materials. A support 7 is fixed to the lower end of the rotating motor 6, and the left end of the support 7 is welded to the right surface of the crushing box 1. The support 7 is used to support the rotating motor 6 so that the rotating motor 6 runs in a stable environment. The outer surface of the horizontal axis 5 is welded with a first blade 8, The second blade 9 and the third blade 10, the number of the first blade 8 is less than the number of the second blade 9, and the number of the second blade 9 is less than the number of the third blade 10, the lower surface of the crushing box 1 is provided with three discharge ports 15, the first blade 8, the second blade 9 and the third blade 10 are respectively installed with a first filter screen 11, a second filter screen 12 and a third filter screen 13, and the diameter of the filter hole on the first filter screen 11 is larger than the diameter of the filter hole on the second filter screen 12, and the diameter of the filter hole on the second filter screen 12 is larger than the diameter of the filter hole on the third filter screen 13, the horizontal axis 5 drives the first blade 8, the second blade 9 and the third blade 10 to rotate, and by changing the inside of the crushing box 1 The number of blades in the three areas makes it easy to crush the coal raw material into particles of different sizes, thereby improving the practicability of the device. A gathering plate 14 is arranged below the first filter 11, the second filter 12 and the third filter 13, and the lower end of the gathering plate 14 is connected to the discharge port 15. Through the arrangement of the first filter 11, the second filter 12 and the third filter 13, the coal raw material that has not been successfully crushed can be intercepted until the coal raw material is crushed. The crushed raw material is discharged from the discharge port 15 through the corresponding filter and falls into the corresponding collection box 19 to avoid mixing of the coal raw materials. The arrangement of the gathering plate 14 facilitates the discharge of the crushed raw materials.

[0021] The collecting box 19 is arranged below the discharge port 15, and a base 18 is arranged at the lower end of the collecting box 19, and support plates 17 are welded on both sides of the upper surface of the base 18. A vibration motor 16 is installed on the left side of the crushing box 1, and the crushing box 1 is connected to the base 18 through the support plate 17. When the filter holes on the first filter screen 11, the second filter screen 12 and the third filter screen 13 are blocked, the vibration motor 16 is started to generate vibration force to pass through the filter screen, so as to facilitate the discharge of the coal raw materials.

[0022] Working principle: the internal space of the crushing box 1 is divided into three areas by the first partition 3 and the second partition 4. The coal raw materials can be injected into the three areas inside the crushing box 1 through the three feed ports 2. The rotating motor 6 is started by the controller 20, and the rotating motor 6 drives the horizontal axis 5 to rotate, so that the first blade 8, the second blade 9 and the third blade 10 installed on the outside of the horizontal axis 5 rotate. The number of the first blades 8 is less than the number of the second blades 9, and the number of the second blades 9 is less than the number of the third blades 10. By changing the number of blades in the three areas inside the crushing box 1, the coal raw materials are crushed into particles of different sizes. Corresponding filters are arranged under the corresponding blades, specifically, the first filter 11, the second filter 12 and the third filter 13, which can intercept the coal raw materials that have not been successfully crushed until the coal raw materials are crushed. The crushed raw materials are discharged from the discharge port 15 through the corresponding filter and fall into the corresponding collection box 19 to avoid mixing of the coal raw materials. When the filter holes on the filter are blocked, the vibration motor 16 is started by the controller 20 to generate vibration force to pass through the filter to facilitate the discharge of the coal raw materials.

[0023] The device is controlled automatically by the controller 20. The control circuit of the controller 20 can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field.
