Hopper used for mixer and having crushing and anti-sticking functions

The invention discloses a hopper used for mixer and having crushing and anti-sticking functions. The hopper comprises a hopper body, power devices, driving devices and a crushing and anti-sticking mechanism, wherein the hopper body and the power devices adopt an integrated structure, the crushing and anti-sticking mechanism is arranged in the hopper body, and the driving devices are symmetricallyarranged relative to the central line of the crushing and anti-sticking mechanism. The hopper comprises an inner hopper and an outer hopper on the whole, cutting rings can constantly reciprocate vertically, each cutting ring comprises multiple cylinders with different inner diameters, accordingly, materials can be sufficiently chopped, the materials can be sufficiently mixed, the working efficiency is improved, the phenomenon of material sticking to the surface of the inner hopper can be effectively eradicated through matching of a scraper blade, the materials can smoothly slide into mixing equipment, the feeding effe
