Abstract

The invention relates to a crushing machine processing device, in particular to a spiral feeding type fine crushing machine. The crushing machine comprises a spiral machine barrel provided with a discharging opening, a feeding opening is formed in the upper portion of the spiral machine barrel, a gear motor is arranged at the back end and is fixedly connected with a spiral conveying shaft inside the spiral machine barrel, the spiral conveying shaft comprises a screw and a paddle wound around the screw, and at least a part of the paddle is located below the feeding opening; a guide head is further arranged at the end of the spiral conveying shaft, during matching, the screw and the paddle wound around the screw are arranged in a cylindrical inner cavity of a feeding section, and the guide head is arranged in the cylindrical inner cavity of a guide section; and a crushing device is further connected to the discharging opening and comprises a crushing cavity and a crushing cutter arranged in the crushing cavity. Constant-speed feeding can be guaranteed; and continuous feeding is carried out through the screw, and traditional feeding discontinuity is avoided. Dust flying at the feeding opening during transferring is avoided while spiral material transferring is carried out.

Description

technical field [0001] The invention relates to a crusher. Background technique [0002] At present, in crushers or in the field of fine crushing, most of the traditional feeding methods use flat-plate stacking feeding. The pusher plate sends a pile of materials to the crushing chamber during work and then pushes them again, and pushes them repeatedly. The process has a certain gap, resulting in too long feeding time. At the same time, the action of the pushing plate depends on the hydraulic or air source. [0003] In addition, when the material enters the crushing cavity, it collides or cuts with the crushing knife on the rotor to be crushed; due to the irregular size of the material, some materials are easy to collide and cut each other twice or multiple times in the crushing cavity. In this way, it is easy to accumulate more materials in the crushing chamber due to the lag of crushing time, which will affect the uniform advancement of materials and cause the retention o...
