Abstract
A centralized mono-lever control system applied to a plurality of actuators of a grader replaces a plurality of manual mechanical operating handles of the grader, and causes all motions of the grader to be centralized on a right hand cross mono-lever; the motions of a multi-way dual valve can be operated in an X-axis direction and a Y-axis direction respectively; through a function selection switch at the top of the lever, a main oil circuit selector valve is controlled to select current operating motions of the lever, so that the left land is freed to conduct operations such as steering and the like. The mono-lever control has the advantages of simple and convenient control, high control comfort, and low labor intensity of a driver.
Description
Technical field
The utility model relates to a kind of control system of land leveller, is applicable to the centralized control of a plurality of executive components of land leveller, particularly a kind of land leveller mono-lever control system.
Background technology
The action of land leveller executive component is controlled by multiple directional control valve, the land leveller multiple directional control valve adopts the armstrong's patent operation at present, because executive component is more, operating grip quantity is also many, has usually about ten, is distributed in the instrument desk both sides, need the right-hand man to operate respectively, handle complexity, driver's labour intensity height, handling comfort is poor.
Summary of the invention
In order to improve land leveller maneuvering performance and comfortableness, reduce driver's labour intensity, the purpose of this utility model provides a kind of land leveller mono-lever control system, make the manipulation of a plurality of executive components concentrate on the cross axle monolever, control by the right hand, handle simple and conveniently, reduced driver's labour intensity, handling comfort is good.
The technical scheme that its technical problem that solves the utility model adopts is: cross axle monolever (16) is installed on the operation panel on driver's chair right side, there is steering wheel in the place ahead at driver's chair, at the top of cross axle monolever (16) functional select switch (14) is arranged, functional select switch (14) is connected with electromagnetism selector valve (11), at the middle part of cross axle monolever (16) enable switch (15) is arranged, enable switch (15) is connected with guide's oil sources valve (17), guide's oil circuit (a of cross axle monolever (16) and two banked direction control valves (12), b) connect, gear pump (13) is connected with electromagnetism selector valve (11) by two banked direction control valves (12).
Beneficial effect: owing to adopted such scheme, can operate the action of two banked direction control valves respectively in X-axis and Y direction, by handle top functional select switch control working connection selector valve, select current lever operated state, reduce the angle of operating grip quantity, make the manipulation of a plurality of executive components concentrate on the cross axle monolever, monolever is installed in the driver's chair right side, can operate the action of two banked direction control valves respectively in X-axis and Y direction, by handle top functional select switch control working connection selector valve, select current lever operated action, 4 functional select switches can be selected 4 groups of actions successively, add original state, can realize the operation of ten actions altogether, working station indicator can be pointed out current mode of operation.Maneuvering performance is comfortable, and driver's labour intensity is low.
Advantage: make the manipulation of a plurality of executive components concentrate on right hand cross axle monolever, can liberate operations such as left hand turns to, mono-lever control is simple and convenient, and handling comfort is good, and driver's labour intensity is low.

The specific embodiment
Embodiment 1: cross axle monolever 16 is installed on the operation panel on driver's chair right side, there is steering wheel in the place ahead at driver's chair, at the top of cross axle monolever 16 functional select switch 14 is arranged, functional select switch 14 is connected with working connection selector valve 11, at the middle part of cross axle monolever 16 enable switch 15 is arranged, enable switch 15 is connected with guide's oil sources valve 17, cross axle monolever 16 is connected with guide's oil circuit a, the b of two banked direction control valves 12, and gear pump 13 is connected with electromagnetism selector valve 11 by two banked direction control valves 12.
In Fig. 1, gear pump 13 is from the hydraulic oil container oil suction, and pressure oil output is given two banked direction control valves 12, and cross axle monolever 16 is operated two banked direction control valves, 12, two banked direction control valves 12A respectively in X-axis and Y direction, the B mouth is attached to executive component through electromagnetism selector valve 11.Only pinning enable switch 15, make guide's oil sources valve 17 electromagnet energisings after, just have guide oil to supply with cross axle monolever 16, two banked direction control valves 12 just have action when X-axis or Y direction are operated.
In Fig. 3, each functional select switch 14 can be controlled two electromagnetism selector valves 11, controls current status indicator lamp simultaneously, status indicator lamp on the instrument desk and icon indication work at present state.When all functional select switches 14 were not selected, pattern 1 indicator lamp was bright, pins enable switch 15, at X-axis and Y direction difference operational motion 5 and 10; When pinning enable switch 15 and functional select switch 14a, pattern 2 indicator lamps are bright, at X-axis and Y direction difference operational motion 1 and 6; Operation in this way, functional select switch 14b, c, d be respective action 2 and 7,3 and 8,4 and 9 respectively.All functional select switches 14 are from homing position type with enable switch 15.
