Collecting box and cyclone system

The utility model discloses a material collecting box and a cyclone system. Wherein the material collecting box comprises a box body, a buffer layer and a feeding port, materials can enter the box body from the feeding port, the buffer layer is installed at the bottom of the box body, and a plurality of tooth heads are arranged on the buffer layer. And by arranging the tooth head, the impact force from the material at the outlet of the cyclone is reduced. And the cyclone state of the materials is destroyed, the centrifugal spiral flowing state of the materials is changed, then the impact of the materials on the box body is reduced, and the normal service life of the box body is greatly prolonged. The height of the tooth head is relatively moderate, so that the tooth head can be effectively contacted with an outlet material, and the buffering effect of the tooth head is ensured; and on the other hand, the tooth head is not too high, so that the borne impact force is not too large, and the abrasion of the tooth
