Problems solved by technology

However, in actual use, there is such a problem: the existing compression garbage truck hydraulic system transmits power through the power take-off shaft of the chassis engine, and the power is constant, which leads to the failure of the speed of the hydraulic system actuator to increase when the pressure is satisfied. , so that when the on-site operators perform the press-fitting cycle, the working time cannot be shortened, which reduces the efficiency of garbage disposal

Abstract

The invention provides a hydraulic device for a compression type garbage truck and the compression type garbage truck. The hydraulic device comprises an oil storage and supply part used for providing oil required by operation of the hydraulic device; the power device comprises a push shovel power part, a sliding plate power part, a scraping plate power part, a lifting power part and a barrel turning power part; the control valve part is respectively connected with the oil storage and supply part and the power device and is used for controlling the oil in the oil storage and supply part to enter and exit from the power device; the oil pump is arranged between the oil storage and supply part and the control valve part and is used for controlling oil in the oil storage and supply part to enter the control valve part; and the differential control part is arranged between the skateboard power part and the control valve part and is used for accelerating the operation of the skateboard power part. According to the hydraulic device, the differential control part is arranged on the hydraulic device of the compression garbage truck, so that oil in the oil cylinder can run quickly, the operation time is shortened, and the garbage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of garbage trucks, in particular to a hydraulic device for a compressed garbage truck and a compressed garbage truck. Background technique [0002] The compressed garbage truck is a sanitation vehicle used for garbage collection and transfer, which has the characteristics of simple garbage collection and large loading capacity. However, in actual use, there is such a problem: the existing compression garbage truck hydraulic system transmits power through the power take-off shaft of the chassis engine, and the power is constant, which leads to the failure of the speed of the hydraulic system actuator to increase when the pressure is satisfied. , so that when the on-site operators perform the press-fitting cycle, the working time cannot be shortened, which reduces the efficiency of garbage disposal. Contents of the invention [0003] The present invention arranges a differential control unit on the hydrauli...
