Description
Technical field
The utility model belongs to engineering machinery bulldozer technical field, particularly relates to the electric liquid guide control device of a kind of bulldozer operating mechanism.
Background technology
At present, bulldozer operating mechanism: dozer and ridge buster are machinery and hydraulic control substantially.
Common bulldozer adopts hand-operated direction valve control hydraulic cylinder, thereby promotes dozer and ridge buster work.Yet, and dozer is swung up and down thereupon owing to the uneven car body in ground jolts.In order to push away plane earth, the people will usually handle the movement locus that mechanical pull bar is controlled dozer.Therefore, the time one is long, and the operator easily produces fatigue, and inefficiency.
Summary of the invention
The utility model is for solving the problem that prior art exists, and the electric liquid guide control device of a kind of bulldozer operating mechanism is provided.
The purpose of this utility model is for solving the deficiency of above bulldozer, and adaline electrohydraulic integration technology growing improved common bulldozer operability and operating efficiency, attempts with the traditional bulldozer of mechanical-electrical-hydraulic integration technological transformation.
The utility model provides a kind of electric liquid guide mechanism, control hydraulicdirectional control valve, thereby the oil cylinder of control operating mechanism makes dozer and ridge buster work.
Its electric liquid guide mechanism provides electric interfaces, can link to each other with electronic controller or other electrically operated mechanism, realizes electrification or automation that bulldozer operating mechanism handles easily.
The utility model adopts following technical scheme:
The electric liquid guide control device of bulldozer operating mechanism, comprise electromagnetic priority valve, pilot operated directional control valve, oil circuit, electromagnetic priority valve connects pilot operated directional control valve by oil circuit, be characterized in: electromagnetic priority valve has electrical signal line to link to each other with the bulldozer controller, electromagnetic priority valve links to each other with pilot operated directional control valve by oil circuit, and pilot operated directional control valve is connected by the oil cylinder of oil circuit with bulldozer operating mechanism.
The utility model can also be taked following technical measures:
The electric liquid guide control device of described bulldozer operating mechanism, be characterized in: the oil cylinder of bulldozer operating mechanism is the perching knife dump ram.
The electric liquid guide control device of described bulldozer operating mechanism, be characterized in: the oil cylinder of bulldozer operating mechanism is the ridge buster hoist cylinder.
The electric liquid guide control device of described bulldozer operating mechanism, be characterized in: the bulldozer controller is electronic controller or electrically operated mechanism.
The utlity model has following tangible advantage and good effect:
The electric liquid guide control device of bulldozer operating mechanism replaces to electric liquid guide with the hand-operated valve of common bulldozer control hydraulic circuit and controls hydraulic circuit, thereby realizes electrification or automation that bulldozer operating mechanism handles.The utility model is simple in structure, and is easy to operate, and precise control is stable, the automaticity height, thus alleviated working strength greatly, increase work efficiency.
Description of drawings
Fig. 1 is the utility model syndeton schematic diagram.
Among the figure: 1,4-electromagnetic priority valve, 2, the 5-pilot operated directional control valve, 3-perching knife dump ram, 6-ridge buster hoist cylinder.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now.
Embodiment 1
With reference to accompanying drawing 1.The electric liquid guide control device of bulldozer operating mechanism, its electromagnetic priority valve has electrical signal line to link to each other with the electronic controller of bulldozer, the electromagnetic priority valve 1 of two-way parallel connection links to each other with 5 with pilot operated directional control valve 2 by oil circuit respectively with 4, pilot operated directional control valve 2 is connected with the perching knife dump ram 3 of bulldozer by oil circuit, and pilot operated directional control valve 4 is connected with the shovel ridge buster hoist cylinder 6 of bulldozer by oil circuit
Bulldozer perching knife inclination control is achieved in that
Electromagnetic priority valve 1 is to be controlled by the current signal on the bulldozer.Charged when electromagnetic priority valve 1 left end, electromagnetic priority valve 1 is in position, a left side.Pressure oil enters the left end of pilot operated directional control valve 2 by the control of valve 1, and the spool that promotes pilot operated directional control valve makes it to be in position, a left side, and another road pressure oil just is admitted to perching knife inclined cylinder 3 loculuses and perching knife is tilted to the right.Otherwise charged when electromagnetic priority valve 1 right-hand member, controlled pressure oil promotes the spool of pilot operated directional control valve 2, makes it to cross meta when mobile in the opposite direction, the big chamber oil-feed of dump ram, and perching knife is tilted to the left.
Ridge buster lifting control is achieved in that
Electromagnetic priority valve 4 is to be controlled by the current signal on the bulldozer.Charged when electromagnetic priority valve 4 left ends, electromagnetic priority valve 4 is in position, a left side.Pressure oil enters the left end of pilot operated directional control valve 5 by the control of valve 4, and the spool that promotes pilot operated directional control valve makes it to be in position, a left side, and another road pressure oil just is admitted to ridge buster lift cylinders 6 loculuses and makes ridge buster to rising.Otherwise charged when electromagnetic priority valve 4 right-hand members, controlled pressure oil promotes the spool of pilot operated directional control valve 5, makes it to cross meta when mobile in the opposite direction, the big chamber oil-feed of oil cylinder, and ridge buster carries out descending motion.
