[0020] A screen 6 is installed on the inner wall of the housing 4, and a driving motor 1 is installed on the top of the housing 4. An active rotating shaft 5 is installed on the output end of the driving motor 1, and the bottom end of the active rotating shaft 5 extends to the bottom of the screen 6 and is connected to the input end of the gearbox 7. A plurality of crushing and cutting knives 3 are evenly installed on the outer wall of the active rotating shaft 5 above the screen 6;

[0021] The inner wall of the screen 6 is connected to the outer wall of the active rotating shaft 5 via a bearing;

[0022] A feed hopper 2 is installed on one side of the top of the housing 4, and the bottom end of the feed hopper 2 is connected to the interior of the housing 4;

[0024] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, raw materials are put into the feed hopper 2, and these raw materials enter the space above the screen 6 inside the shell 4. At this time, the driving motor 1 is started to drive the active rotating shaft 5 to rotate, so that the crushing and cutting knife 3 cuts and crushes these raw materials. The raw materials that are crushed to a certain extent will pass through the screen 6 and fall smoothly on the grinding plate 13. At this time, the rotation of the active rotating shaft 5 is decelerated through the gearbox 7 to cause the driven output shaft 15 to rotate, and drive the installation box 17 to rotate as a whole. As the installation box 17 rotates, the second bevel gear 21 and the first bevel gear 19 are relatively displaced, so the second bevel gear 21 can drive the rotating rod 18 to rotate around its own axis, so the grinding roller 14 rolls on the grinding plate 13 to grind the raw materials.

At this time, the mounting shell 10 is removed with the help of the sliding block and the sliding groove, and the ground raw materials inside the mounting shell 10 can be collected. After the collection is completed, the mounting shell 10 is reinstalled, and the mounting shell 10 is pushed close to the outer shell 4 with the help of the electric telescopic rod 9 until the top of the mounting shell 10 is against the bottom of the outer shell 4, and the limiting rod 22 is inserted into the limiting ring 23. At this time, the position of the mounting shell 10 is restricted, and the rapid installation of the mounting shell 10 can be completed.
