Abstract

The invention discloses a hydraulic control system for an environmental sanitation sweeper. The hydraulic control system solves he problems that an existing sweeper system is large in energy loss, complex in structure, poor in synchronous performance and incapable of realizing modularization. The hydraulic control system comprises a suction valve set, an oil inlet and return valve set, and a working valve set, wherein the oil inlet and return valve set comprises a main oil inlet, an oil return opening, a pressure compensation valve, a diverter valve, a proportional solenoid valve and a main overflow valve; the pressure compensation valve is used for realizing the flow distribution, and is used for completing the composite action of a suction of the suction valve set and an actuating mechanism of the working valve set; the diverter valve is used for meeting the flow except the working requirement for low-pressure unloading; and the proportional solenoid valve is used for realizing control of the output flow so as to control the speed of the actuating mechanism of the working valve set. The hydraulic control system has the advantages that rapid and large-scale production and processing can be achieved, modular production and assembly can be achieved, organizing production is facilitated, the structure is simple, the assembly is facilitated, the action is reliable, the system energy consumption is small, the synchronization performance is good, service life is long, and the like.

Description

Technical field [0001] The invention relates to an environmental sanitation sweeper, in particular to a hydraulic control system for an environmental sanitation sweeper. Background technique [0002] The road sweeper is a new type of high-efficiency cleaning equipment that integrates road cleaning, garbage recycling and transportation. To put it simply, the special vehicle chassis is modified with road sweeping and water spraying functions. In addition to the chassis engine, the vehicle is equipped with a secondary engine. The sweeping is driven by a hydraulic motor, with fans, trash cans, water tanks, etc. Grouped equipment. This brand-new model can complete ground cleaning, road side cleaning, road side cleaning, and watering of the ground after cleaning. It is suitable for cleaning operations in various climates and different dry roads. [0003] The hydraulic systems of existing sanitation road sweepers are mostly integrated valve blocks mainly composed of on-off plate solenoi...
