Abstract
The utility model relates to an operating device for a loader, in particular to an operating device for a loader with simple structure and convenient operation. The operating device is characterized in that the operating device is provided with a hydraulic pilot valve and a hydraulic pilot oil pump, wherein the hydraulic pilot oil pump is connected with the hydraulic pilot valve through an oil duct, the hydraulic pilot valve is connected with a hydraulic multi-way valve controlling a working arm through an oil duct, speed change box operating buttons are arranged on the operating arm of the hydraulic pilot valve, and the operating buttons are connected with a solenoid valve controlling the speed change box through a lead wire. The operations of the speed change box and the working arm are concentrated on an operating arm through the hydraulic pilot valve and the buttons, the working state of the loader can be controlled by operating an operating arm, therefore, the operating device has the advantages of simple structure, small occupied space, convenient operation and good application effect.
Description
Technical field:
The utility model relates to the control device of loader, particularly a kind of simple in structure, easy to operate loader operation device.
Background technology:
As everyone knows, the operating means that loader not only requires control to travel, also require to have the receipts that lifting, decline and the shovel of control working arm tremble or the operating means of operating means of putting and control gearbox rotating speed, existing these operating means are made up of action bars and lacing wire respectively, function lever apparatus is made up of action bars and base, can control the hydraulic means of gearbox and working arm by lacing wire through action bars, its deficiency is that action bars is numerous, not only take driver's cabin and protect expensive space, also make inconvenient operation, increase operation easier and operator's labour intensity.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of simple in structure, easy to operate loader operation device is provided.
The present invention can reach by following measure:
A kind of loader operation device, feature is to be provided with hydraulic pilot valve, hydraulic pilot oil pump, the hydraulic pilot oil pump is connected with the hydraulic pilot valve through oil guide pipe, the hydraulic pilot valve is connected through the hydraulic multitandem valve of oil guide pipe with the control working arm, the action bars of hydraulic pilot valve is provided with the gearbox action button, and action button is connected through the electromagnetic valve of lead with the control gearbox.
Hydraulic pilot valve described in the utility model is the four-way pilot valve, controls receipts that lifting, decline and the shovel of working arm tremble or the operation of putting respectively.
The utility model action bars is provided with at least two gearbox control buttons, to control the multiple output speed of gearbox better, suitable need of work.
The utility model focuses on the operation of gearbox and working arm on the action bars through hydraulic pilot valve and button, can control the duty of loader by operating an action bars, have simple in structure, little, easy to operate, advantage such as result of use is good takes up room.
