Mixing machine used for mixing materials such as wood scraps and high-polymer materials

The invention relates to a mixing machine, in particular to a mixing machine used for mixing materials such as wood scraps and high-polymer materials with an aim to solve technical problems by providing the mixing machine convenient in blanking and capable of mixing the materials by stirring constantly up and down. The mixing machine comprises a mixing box and the like; each of the left portion of the top wall of the mixing box and the bottom wall of the mixing box are provided with a first through hole, the bottom of the left wall of the mixing box is rotatably connected with a first retaining plate, the left side of the bottom of the first retaining plate is fixed at the bottom end of the left wall of the mixing box in a threaded connection manner, and mechanisms are arranged in the mixing box in bilateral symmetry. By the arrangement of a driving mechanism and a stirring mechanism, the materials such as the wood scraps and the high-polymer materials obtained by being poured into the mixing box and smashed
