Description
Technical field：
The present invention relates to agricultural machinery technological field, more particularly to a kind of Light Crawler Tractor turns to be controlled
Mechanism processed.
Background technology：
The left and right turn of domestic at present common Light Crawler Tractor manipulates mainly two kinds of structures：The first pulls
Operating board left and right turn handle, by pivoted arm, cylinder lever connecting rod etc., on direct pull change speed gear box, steering arm rotates, and realizes machine
Turn to, its advantage is that structure is simple, easily manufactured, low cost；Shortcoming is rustic, especially draw change hands handle when stroke big,
There is interference with operator from body.Second is to be provided with steering wheel, steering wheel rotation on operating board, and under drive, pivoted arm turns
Dynamic, pull steering arm on change speed gear box to rotate by cylinder lever connecting rod, realize the steering of machine, its advantage is to be controlled with steering wheel to turn
To, compact structure is attractive in appearance；Shortcoming is that steering wheel rotates drive pivoted arm pulling steering, and steering wheel resistance is big, and operation steering takes very much
Power, long-time operation is easily tired.
Content of the invention：
The purpose of the present invention be for the deficiencies in the prior art in place of, a kind of Light Crawler Tractor course changing control is provided
Mechanism, it is simple for structure, suitable Light Crawler Tractor structure space, easy and simple to handle, practical reliable.
The technology solution of the present invention is as follows：
A kind of Light Crawler Tractor course changing control mechanism, including electromotor, change speed gear box and master operating station, electromotor with
Change speed gear box links together；Described master operating station is located at engine right side, the upside of change speed gear box；It is provided with described master operating station
One steering operation bar, master operating station bottom is provided with a steering hydraulic valve, is connected one between steering operation bar and steering hydraulic valve
Connecting rod；Equipped with steering cylinder on described change speed gear box, steering cylinder left end is connected with left and right steering oil pipe, is provided with steering cylinder
Left and right steering push rod, change speed gear box has left and right steering arm, and left steering push rod can promote left steering arm to rotate, and right turn push rod can
Right turn arm is promoted to rotate；Described steering hydraulic valve is connected with steering cylinder by left and right steering oil pipe.
Described steering operation bar is turned to fuel-displaced, by the left to the left or to the right by the valve rod that connecting rod promotes steering hydraulic valve
Turn to fuel-displaced, can promote steering cylinder left steering push rod eject promote left steering arm so that it is turned left, to realize machine to
Left steering；Fuel-displaced by turning to the right, the right turn push rod of steering cylinder can be promoted to eject and to promote right turn arm so that it is turned right
Dynamic, to realize machine and to turn to the right.
It is made to turn to preferably, described steering operation bar can promote to the left or to the right.
Preferably, being provided with pilot set on described master operating station.
Preferably, the upper end of described steering operation bar is provided with a lever.
Preferably, described steering cylinder is fluid-link steering oil cylinder.
The beneficial effects of the present invention is：
During present invention work, promote steering operation bar to the left or to the right, to control the left and right steering oil pipe of steering hydraulic valve
Fuel-displaced, for promoting the left and right steering push rod ejection of steering cylinder, promote the left and right steering arm of change speed gear box, to realize machine to
Left or turn to the right.Present configuration is succinct, compact, and steering operation bar small range is manipulated, and just can achieve that machine turns to；This
The bright small range by steering operation bar manipulates the work controlling steering hydraulic valve, therefore only needs the power of very little to operate, and reduces tired
Labor；The present invention promotes left and right steering arm to realize turning to by fluid-link steering oil cylinder, reduces the connecting rod of former mechanism, torque arm connects
Practice midwifery raw gap, realize accurately controlling, good reliability.
Brief description：
The present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is the front view of the present invention；
Fig. 2 is the top view (not comprising pilot set) of the present invention；
Fig. 3 is the steering operation schematic diagram of the present invention.
Specific embodiment：
Embodiment, is shown in accompanying drawing 1～3, a kind of Light Crawler Tractor course changing control mechanism, including electromotor 1, change speed gear box
2 and master operating station 3, electromotor is linked together by clutch with change speed gear box；Described master operating station is located at engine right side, becomes
The upside of fast case；One steering operation bar 4 is provided with described master operating station, master operating station bottom is provided with a steering hydraulic valve 5,
It is connected a connecting rod 6 between steering operation bar and steering hydraulic valve；Equipped with steering cylinder 7 on described change speed gear box, steering cylinder left end
It is connected with left and right steering oil pipe 8,9, be provided with left and right steering push rod 10,11 in steering cylinder, change speed gear box has left and right steering arm
12nd, 13, left steering push rod can promote left steering arm to rotate, and right turn push rod can promote right turn arm to rotate；Described steering hydraulic
