Hydraulic power device of dual-axis shearing type crusher

Abstract

The invention discloses a hydraulic power device of a dual-axis shearing type crusher, relates to the technical field of hydraulic power systems, and aims to solve the problem that an existing hydraulic power system is not beneficial for heat dissipation and maintenance, and is easily polluted. According to the technical scheme, the key point is that the hydraulic power device comprises a closed type hydraulic station and an external pipeline, wherein a hydraulic motor is connected to the closed type hydraulic station through an external pipeline; the closed type hydraulic station comprises acabinet type box body with a plurality of shutters on four side walls, a square tube beam, and an oil tank assembly, wherein an air cooler is mounted on the top of the cabinet type box body, the square tube beam is arranged on the middle part of the cabinet type box body for dividing the cabinet type box body into an upper box body and a lower box body from top to bottom; the oil tank assembly isborne on the square tube beam, and is positioned in the upper box body; and a motor pump group, an energy accumulator group and a flushing valve group are arranged in the lower box body. The motor pump group comprises a motor, a main pump and a gear pump, the main pump and the gear pump are positioned below the oil tank assembly, and the motor is positioned at one side of the oil tank assembly. The hydraulic power device facilitates heat dissipation and maintenance, and has a dustproof function.

Description

technical field [0001] The invention relates to the technical field of hydraulic power systems, in particular to a hydraulic power device for a double-shaft shearing crusher. Background technique [0002] Shear crusher, also known as shredder, is a general-purpose equipment in the solid waste treatment and crushing industry. In the traditional double-shaft shearing crusher, the ordinary motor is often used to drive the reducer to drive the cutter shaft to rotate, and the large materials are cut, squeezed and torn into small-sized materials, but the power load of the motor is small. , Insufficient torque, if overload occurs, the motor will burn out due to overload, and the machine will not work stably. [0003] In order to solve the above problems, most of the power systems of hydraulically driven crushers in the prior art are open hydraulic stations that use high-speed hydraulic motors to drive the reducer to drive the cutter shaft to rotate, for example: [0004] The Chin...

Problems solved by technology

[0005] However, the above-mentioned existing technical solutions have the following defects: the above-mentioned shear crusher hydraulic station has an unreasonable structural design, and its components are arranged together, which is not conducive to heat dissipation and maintenance, and because the hydraulic station is still exposed structure, so it is easy to be polluted and needs to be shut down frequently for cleaning, which seriously affects the production schedule
