A garbage truck hydraulic control system and garbage truck

Abstract

The invention discloses a rubbish truck hydraulic control system which comprises an oil tank. The upper side of the oil tank is connected with an oil pump. An oil outlet of the oil pump is connected with an oil outlet pipe. The oil outlet pipe is sequentially provided with a first electromagnetic directional valve, a second electromagnetic directional valve, a third electromagnetic directional valve and a fourth electromagnetic directional valve in parallel. A main oil return opening T of the first electromagnetic directional valve, a main oil return opening T of the second electromagnetic directional valve, a main oil return opening T of the third electromagnetic directional valve and a main oil return opening T of the fourth electromagnetic directional valve all communicate with the oiltank through the same oil return pipe. The first electromagnetic directional valve is connected with a suction cup lifting oil cylinder. The second electromagnetic directional valve is connected witha brushing lifting oil cylinder. The third electromagnetic directional valve is connected with a rubbish bin cover plate opening and closing oil cylinder. The fourth electromagnetic directional valveis connected with a rubbish bin lifting oil cylinder. The invention further discloses a rubbish truck. According to the rubbish truck hydraulic control system and the rubbish truck, movements of multiple working mechanisms can be controlled at the same time through the set of the hydraulic control system, and therefore production cost is obviously reduced and the control difficulty of the hydraulic system is lowered.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, more specifically, to a hydraulic control system for a garbage truck and the garbage truck. Background technique [0002] Garbage truck refers to a special vehicle specially used by the municipal sanitation department to transport all kinds of garbage. Garbage trucks are mainly used for municipal sanitation and large-scale factories and mines to transport all kinds of garbage, especially for transporting household garbage in residential quarters, as well as for transporting bulk building materials such as ash, sand, stone, soil, etc., and for transporting ore or coal in mines or coal construction . The birth and development of garbage trucks have greatly improved the living environment of human beings, especially in cities where the population is concentrated and the amount of garbage generated every day is large, and the urban land is limited. Once the garbage cannot be dispose...

AI Technical Summary

Problems solved by technology

[0003] In actual operation, because there are often many working mechanisms that need to be controlled in motion on the garbage truck, such as suction cups, sweeping brushes, garbage bins, etc., and the existing hydraulic control system of garbage trucks has limitations, resulting in suction cups, sweeping brushes, garbage bins, etc. The control of etc. often requires a set of independent hydraulic control system, so that multiple sets of hydraulic control systems need to be installed on the garbage truck, which not only increases the production cost, but also increases the difficulty of controlling the hydraulic system.
