Description
Technical field
The utility model relates to the control system of land leveller, relates in particular to a kind of land leveller with hydraulic control stick control device.
Background technology
Land leveller mechanism is complicated, and various, the traditional land leveller that moves adopts manual multiple-way valve control, because executive component is numerous, control crank is also many, has usually about ten, is distributed in the console both sides, and pilot control is complicated, and working strength is big, and comfortableness is poor.
The utility model content
The purpose of the utility model is, overcome prior art by part, provide a kind of land leveller with hydraulic control stick control device, improve the maneuvering performance and the comfortableness of land leveller, reduce driver's labour intensity.
The described a kind of land leveller of the utility model includes guide's oil sources electromagnetic valve, auxiliary pilot control valve, right pilot control valve, left pilot control valve, pilot control reversing solenoid valve group and hydraulic control multiple directional control valve and forms with hydraulic control stick control device.Guide's oil sources electromagnetic valve is a master switch, is set side by side with auxiliary pilot control valve with guide's oil sources electromagnetic valve.At first to connect guide's oil sources electromagnetic valve when the driver gets on the bus, be right pilot control valve and left pilot control valve fuel feeding.Guide's oil sources electromagnetic valve is connected with left pilot control valve with right pilot control valve through oil pipe line; Right pilot control valve and left pilot control valve are connected with a pilot control reversing solenoid valve group separately through oil pipe line, and each pilot control reversing solenoid valve group is connected with a hydraulic control multiple directional control valve.Left side pilot control valve is installed on the left armrest box, and right pilot control valve and auxiliary pilot control valve are installed on the right armrest box, are respectively equipped with change-over switch at the top of left pilot control valve, right pilot control valve and auxiliary pilot control valve.When getting on the bus, the driver at first to connect guide's oil sources electromagnetic valve; Be right pilot control valve and left pilot control valve fuel feeding; Through handling auxiliary pilot control valve, right pilot control valve and left pilot control valve; Can directly control the direction and the spool aperture of 5-linked hydraulic control multiple directional control valve, control the switching-over of pilot control reversing solenoid valve group, thereby control the direction and the spool aperture of the hydraulic control multiple directional control valve of other 5-linkeds through change-over switch.The preceding perching knife of land leveller and ridge buster can be selected according to the user for the apolegamy device, the installation of the auxiliary pilot control valve of allotment be connected.
The described a kind of land leveller of the utility model is with hydraulic control stick control device, and overall structure is simple, and is easy for operation, good stability, and reliability is high.The said a kind of land leveller of the utility model is with hydraulic control stick control device, and handling safety reliably, the problem of maloperation can not take place; Change-over switch is set on control crank, the control function is doubled, reduced control crank quantity, handle simple; On the armrest box of the left and right sides, make pilot control more comfortable, more ergonomic the control crank design; Adopt the hydraulic control multiple directional control valve, each responsiveness speed is controlled, is convenient to the driver and carries out some small adjustment.Be applicable to the simplification and the raising of handling comfort level of land leveller control system.The control system that the utility model provides a kind of land leveller to adopt the hydraulic control handle concentrates on the manipulation of a plurality of executive components on the handle of the left and right sides, handles simple and conveniently, and comfortableness is good, greatly reduces driver's labour intensity.
