Breaking machine

Abstract

The invention discloses a breaking machine. The breaking machine comprises a machine shell, wherein an operation door is arranged on the side wall of the machine shell; a screen used for dividing an inner cavity of the machine shell into a breaking chamber and a collecting chamber is arranged in the machine shell; the breaking chamber is communicated with a feeding port formed in the upper end of the machine shell; the screen is connected with the machine shell through a screen pressing mechanism; a rotor is arranged in the breaking chamber and connected with the machine shell; the rotor comprises a rotor shaft, multiple cutter heads, multiple cutter shafts and multiple blades; the cutter heads are arranged on the rotor shaft; each cutter shaft is connected with all the cutter heads; all the cutter shafts are evenly distributed in the circumferential direction of the cutter heads; the blades are arranged on the portions, between every two adjacent cutter heads, of the cutter shafts; and multiple cutting teeth are arranged at the cutting ends of the blades. According to the breaking machine, the service life of the blades can be prolonged.

Description

technical field [0001] The invention relates to the technical field of breakers, in particular to a breaker. Background technique [0002] When using a crusher to crush waste paper and other materials, the rotor in the crusher is mainly used to cut and crush the materials. Existing rotor structures such as Figure 15 As shown, the rotor 4 includes a rotor shaft 4-1, a cutter head 4-2, a cutter shaft ( Figure 15 Not shown in), blade 4-4, a plurality of cutterheads 4-1 are installed on the rotor shaft 4-1, the cutter shaft is provided with a plurality of, each cutter shaft is connected with all cutter heads 4-2, all The cutter shafts are evenly distributed along the circumferential direction of the cutter heads 4-2, and blades 4-4 are arranged on the cutter shafts between two adjacent cutter heads 4-2. [0003] During the rotation of the rotor 4, if Figure 15 A corner of the cutting end of the blade 4-4 shown can cut the material, for example, in the process of the clockwis...

AI Technical Summary

Problems solved by technology

During the rotation of the rotor 4, once the corner of the cutting end of the blade 4-4 is damaged, for example, the corner of the cutting end of the blade 4-4 is broken by stones mixed in the material when cutting the material, and the blade 4-4 cannot continue to be used , which shortens the service life of the blade 4-4, and then requires time-consuming downtime to replace the blade 4-4, which not only reduces the crushing efficiency, but also increases the material cost
