Abstract

The invention relates to a rear-loading garbage compression truck hydraulic device. The rear-loading garbage compression truck hydraulic device comprises a fuel tank, an oil pump, a push-plate valve group and a push-plate oil cylinder connected through an oil circuit. The push-plate valve group is connected with a control valve with adjustable opening pressure. The control valve is connected witha controller of a garbage compression truck. The rear-loading garbage compression truck hydraulic device can control the compressive force of a push plate when compressing the garbage according to types of organic garbage or inorganic garbage. For the organic garbage, the organic waste is compressed compactly by setting high opening pressure of the control valve, and for the inorganic garbage, theorganic garbage is compactly compressed by setting low opening pressure of the control valve, so as to ensure that the garbage compression truck does not have the problems of overload and space waste.

Description

technical field [0001] The invention relates to the technical field of garbage compression hydraulic control equipment, in particular to a rear-mounted hydraulic device for a garbage compression vehicle. Background technique [0002] With the urbanization of our country, the composition of urban domestic waste has undergone great changes. According to the density of waste, it can be divided into inorganic waste and organic waste. Promise waste refers to the waste of inorganic components in domestic waste. Composed of inorganic substances decomposed by microorganisms, such as plastics, glass, etc.; organic waste refers to waste containing organic components in domestic waste, most of which can be decomposed by microorganisms, mainly paper, fiber, bamboo, wood, kitchen waste, etc., urban life More than 50% of the garbage is compressible organic waste. With the improvement of people's awareness of environmental protection, the growth rate of compressible organic waste is accel...
