Abstract
The utility model relates to a working hydraulic system for a trash compacting machine. The system comprises an energy accumulator, a refill valve, a steering operation handle, a blade lift operation handle, a multi-path valve and a work pump, wherein an engine is connected with a torque converter to drive the work pump to rotate to supply an oil source to the hydraulic system; after passing through the refill valve, the working oil source is divided into a high pressure oil source and a low pressure oil source, the low pressure oil source fills liquid in the energy accumulator, and the energy accumulator supplies the working oil source for braking the hydraulic cylinder; when the pressure of the energy accumulator is reduced to a certain value, the refill valve supplies oil for the energy accumulator first; and when the energy accumulator is filled with oil, the refill valve supplies the oil to the multi-path valve, and the multi-path valve is controlled by virtue of the steering operation handle and the blade lift operation handle, so that lifting of a blade hydro-cylinder and expansion of the steering hydro-cylinder are realized. The working hydraulic system has the advantages that: reversing of the multi-path valve is controlled by an electric control handle to control the steering hydro-cylinder, so that a conventional steering gear and a steering wheel are not used any more, the structure is simpler, and the operation is more comfortable and more convenient.
Description
Technical field
The utility model relates to a kind of compactor, relates in particular to a kind of compactor hydraulic system of working.
Background technology
The gas mode of braking is generally adopted in compactor service brake at present, and the working barrel oil sources can only offer the perching knife lifting and turn to, and engine power can not be fully by the hydraulic system utilization, and power loss is big.Steering adopts conventional mode of operation such as steering gear, steering wheel, and complex structure, comfortableness are poor.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of simple in structure, the compactor hydraulic system of working that prefill valve can unite two into one high and low pressure system can be controlled banked direction control valves through electric control handle, realizes the up-down of perching knife and turns to.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
A kind of compactor hydraulic system of working comprises that accumulator 1, prefill valve 2, steering operation handle 3, perching knife promote operating grip 4, banked direction control valves 5, working barrel 6, and engine connects torque-converters and drives working barrel 6 rotations; For hydraulic system provides oil sources, the work oil sources is divided into high-low pressure two-way oil sources through behind the prefill valve 2; Its mesolow one tunnel is accumulator 1 topping up; Accumulator 1 provides the work oil sources for hydraulic braking system, and when accumulator 1 pressure was reduced to certain value, prefill valve 2 was preferably accumulator 1 and replenishes fluid; When accumulator 1 is full of fluid; Prefill valve 2 is supplied with banked direction control valves 5 with fluid, promotes operating grip 4 through steering operation handle 3, perching knife and controls banked direction control valves 5, realizes the up-down of perching knife oil cylinder and turns to the flexible of oil cylinder.
The beneficial effect of the utility model is: the shared working barrel of high and low pressure system; Prefill valve partly unites two into one system's high-low pressure, and power loss is little, and system adopts the solenoid-operated proportional load sensing multi-way valve; The perching knife of load feedback promotes and steering hydraulic system, increases work efficiency.Being commutated to control by electric control handle control banked direction control valves turns to oil cylinder, has saved conventional steering gear, steering wheel, and structure is simpler, operates more comfortable convenience.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-accumulator, the 2-prefill valve, 3-steering operation handle, the 4-perching knife promotes operating grip, 5-banked direction control valves, 6-working barrel.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the described a kind of compactor hydraulic system of working of this specific embodiment comprises that accumulator 1, prefill valve 2, steering operation handle 3, perching knife promote operating grip 4, banked direction control valves 5, working barrel 6; Engine connects torque-converters and drives working barrel 6 rotations, and for hydraulic system provides oil sources, the work oil sources is through behind the prefill valve 2; Be divided into high-low pressure two-way oil sources, its mesolow one tunnel is accumulator 1 topping up, and accumulator 1 provides the work oil sources for hydraulic braking system; When accumulator 1 pressure is reduced to certain value; Prefill valve 2 is preferably accumulator 1 and replenishes fluid, and when accumulator 1 was full of fluid, prefill valve 2 was supplied with banked direction control valves 5 with fluid; Promote operating grip 4 through steering operation handle 3, perching knife and control banked direction control valves 5, realize the up-down of perching knife oil cylinder and turn to the flexible of oil cylinder.
The beneficial effect of this specific embodiment is: the shared working barrel of high and low pressure system; Prefill valve partly unites two into one system's high-low pressure, and power loss is little, and system adopts the solenoid-operated proportional load sensing multi-way valve; The perching knife of load feedback promotes and steering hydraulic system, increases work efficiency.Being commutated to control by electric control handle control banked direction control valves turns to oil cylinder, has saved conventional steering gear, steering wheel, and structure is simpler, operates more comfortable convenience.
