Embodiment Construction

[0011] See figure 1 , figure 2 The cutter shaft of the garbage crusher in the embodiment of the present invention includes a shaft body 1 and a number of blades 2 uniformly distributed on the shaft body 1 at a certain angle (usually 15-40 degrees) in the axial direction. The blades 2 include a cutter head part. 3. Blade part 4 and blade body part 5. The number of blades 2 is preferably 8-20. Each blade 2 has two correspondingly distributed (symmetrically distributed, 180-degree distribution in the axial section) of the tip part 3, the blade part 4 and the blade body part 5, such as figure 2 Shown. This structure enables the cutter head to have only two symmetrical cutter teeth (the sharp part of the cutter head part 3) in a certain direction, and the distance between the two cutter teeth and the fixed blade is relatively large, which is conducive to the cutter teeth grasping and being broken Large objects and apply torque to tear and squeeze broken objects in time, while t...

Abstract

The invention discloses a cutter shaft of a garbage crusher. The cutter shaft comprises a shaft body and blades, wherein the blades are fixedly connected with the shaft body. The cutter shaft is characterized in that the blades consist of cutter head parts, cutter edge parts and cutter body parts; the blades are spirally and evenly distributed in the axial direction of the shaft body; each of the blades has two cutter head parts, cutter edge parts and cutter body parts correspondingly arranged; included angles of the adjacent blades in the axial direction are within 15-40 degrees; 8-20 blades are provided; and the cutter edge parts are U-shaped. The material of the shaft body is high-strength alloy steel; and the materials of the blades are materials with high wear resistance. The cutter shaft of the garbage crusher has such characteristics as simple structure, convenience for mounting and debugging, high torque and high reliability; the maximum torque of the cutter shaft can bear 80 kN.m; and the cutter shaft is uniform in crushing, and can realize rough crushing of garbage.

Description

Technical field [0001] The invention relates to a knife shaft of a garbage crusher for rough crushing before garbage incineration and power generation. Background technique [0002] At present, most domestic waste is handled by landfill, which has occupied land resources for a long time and pollutes the environment. Now, waste incineration power generation is gradually used to treat domestic waste. The waste must be crushed and pretreated before incineration for power generation to obtain higher heating value and reduce environmental pollution. Garbage crushers have developed rapidly abroad in recent years, and the country mainly relies on imported equipment. When the garbage crusher is working, it is crushed by the low-speed and high-torque cutter shaft, so the cutter shaft is required to withstand large torque. [0003] The cutter shaft of the existing crusher generally does not meet the requirements of large torque, the blade wears quickly and the effect of crushing large piec...
