Problems solved by technology

[0003] In the actual use of the shearing crusher in the prior art, due to the complex composition of the crushed materials, sometimes some high-strength materials cannot be crushed, so it is usually necessary to be equipped with an electric motor with a larger rated power to complete the crushing work. Just cause the power of the whole machine to be high, the cost is higher, in addition also need to be equipped with the speed reducer, increased the total weight of the whole machine

Abstract

The invention relates to a crusher, in particular to a four-axis shearing crusher and aims to provide a four-axis shearing crusher wide in speed regulation range, high in torque, light in overall weight, good in radiating performance and flexible in shearing. The four-axis shearing crusher comprises a housing, four blade shafts mounted in the housing, a discharge door disposed on the housing and a hydraulic system; the hydraulic system comprises four variable pup and quantitative pump closed hydraulic systems, a gear pump and hydraulic cylinder subsystem, a cooling system and a hydraulic oil tank; the four variable pup and quantitative pump closed hydraulic systems each drive one blade shaft to rotate, the gear pump and hydraulic cylinder subsystem drives the discharge door to move, and the cooling system decreases temperature of hydraulic oil; the hydraulic oil tank has high volume, ensuring system oil supply, and the hydraulic oil can be cooled by the hydraulic oil tank.

Description

technical field [0001] The invention relates to a crusher, in particular to a four-shaft shearing crusher. Background technique [0002] Shear crusher, also known as shredder, is the most commonly used crusher in the solid waste treatment industry. Shear crusher mainly relies on the principle of "shear and cut" to complete the process of crushing solid waste. Shear crusher The machine can disassemble large solid waste into pieces with a diameter of less than 100mm, and is widely used in the crushing of waste plastics, waste rubber, wood, domestic garbage and other large-volume waste. The main structure of the shearing crusher is composed of a knife shaft, which is driven by a motor to cut, squeeze, and tear through the knife to reduce the size of the material. [0003] In the actual use of the shearing crusher in the prior art, due to the complex composition of the crushed materials, sometimes some high-strength materials cannot be crushed, so it is usually necessary to be ...
