[0002] A crusher is a machine that crushes large-sized solid raw materials into required sizes. In the crushing process, the external forces applied to the solid are shear, impact, rolling, and grinding. Shear is mainly used in coarse crushing (breaking) and crushing operations, and is suitable for the crushing or grinding of materials with toughness or fibers and large pieces; impact is mainly used in grinding operations and is suitable for the grinding of brittle materials; rolling is mainly used in high-fineness grinding (ultrafine grinding) operations and is suitable for the ultrafine grinding of most materials; grinding is mainly used in ultrafine grinding or ultra-large grinding equipment and is suitable for further grinding operations after grinding.

[0037] The working principle of a multi-stage crusher of the present utility model is as follows:

[0038] Put the raw materials into the raw material cylinder 2. When feeding, start the feeding motor 21. The feeding motor 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the feeding plate 23 to rotate. When the feeding plate 23 rotates, the raw materials in the raw material cylinder 2 fall out of the raw material cylinder 2 along with the rotation of the feeding plate 23 and drop onto the feeding table 31. The raw materials fall into the feeding port 12 along the inclined feeding table 31 and enter the crushing box 1. The bidirectional output motor 14 drives the upper power shaft 141 and the lower power shaft 15 to rotate. The upper power shaft 141 and the lower power shaft 15 drive the first crushing blades 142 and the second crushing blades 151 to rotate. The raw materials entering the crushing box 1 are crushed by the first crushing blades. If further crushing is required, pull out the plug board 133 at the feeding port 132. At this time, the feeding port 132 is opened. The upper power shaft 141 drives the pushing plate 143 to rotate, so that the raw materials piled up on the partition plate 13 after crushing are pushed into the feeding port 132, and the raw materials continue to be crushed by the second crushing blades 151, and finally discharged from the second discharge port 17. If only one-time crushing is required, pull out the plug board 133 at the discharge port 131. At this time, the pushing plate 143 pushes the raw materials crushed once into the discharge port 131, and the raw materials are discharged from the first discharge port 16.

[0039] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
