Description
Technical field:
The present invention relates to agricultural machinery technological field, relate in particular a kind of Light Crawler Tractor and turn to control mechanism.
Background technology:
The left and right turn of domestic common Light Crawler Tractor is handled and is mainly contained two kinds of structures at present: the first pull operation platform left and right turn handle, by pivoted arm, cylinder lever connecting rod etc., on direct pull change speed gear box, spindle arm rotates, realize turning to of machine, its advantage is simple in structure, easily manufactured, cost is low; Shortcoming is rustic, drawing while changing hands handle stroke large, has interference with operator from health especially.The second is that bearing circle is installed on operator's station, steering wheel rotation, and under driving, pivoted arm rotates, and by cylinder lever connecting rod, pulls spindle arm on change speed gear box to rotate, and realizes turning to of machine, and its advantage is to control and turn to bearing circle, and structure is small and exquisite, attractive in appearance; Shortcoming is that rotating of steering wheel drives pivoted arm to pull to turn to, and bearing circle resistance is large, and operation turns to very effort, and long-time operation is easily tired.
Summary of the invention:
The object of the invention is for the deficiencies in the prior art part, provide a kind of Light Crawler Tractor to turn to control mechanism, it is simple for structure, and suitable Light Crawler Tractor structure space is easy and simple to handle, practical reliable.
Technology solution of the present invention is as follows:
Light Crawler Tractor turns to a control mechanism, comprises driving engine, change speed gear box and master operating station, and driving engine and change speed gear box link together; Described master operating station is positioned at engine right side, the upside of change speed gear box; One steering operation bar is installed on described master operating station, and master operating station bottom is provided with a steering hydraulic valve, between steering operation bar and steering hydraulic valve, is connected a connecting rod; On described change speed gear box, steering cylinder is housed, steering cylinder left end is connected with left and right steering oil pipe, is provided with the left and right push rod that turns in steering cylinder, has left and right spindle arm on change speed gear box, left steering push rod can promote left steering arm and rotate, and right steering push rod can promote right steering arm and rotate; Described steering hydraulic valve is connected with steering cylinder by left and right steering oil pipe.
The valve rod that described steering operation bar promotes steering hydraulic valve by connecting rod turns to fuel-displaced to the left or to the right, and by left-handed turning, to fuel-displaced, the left steering push rod that can promote steering cylinder ejects and promotes left steering arm it is turned left, realize machine left-handed turning to; By right-hand turning, to fuel-displaced, the right steering push rod that can promote steering cylinder ejects and promotes right steering arm and makes its turning clockwise, realize machine right-hand turning to.
As preferably, described steering operation bar can promote to make it to turn to the left or to the right.
As preferably, on described master operating station, driver's seat is installed.
As preferably, the upper end of described steering operation bar is provided with a lever.
As preferably, described steering cylinder is fluid-link steering oil cylinder.
Beneficial effect of the present invention is:
When the present invention works, promote to the left or to the right steering operation bar, the left and right steering oil pipe of controlling steering hydraulic valve is fuel-displaced, and the left and right push rod that turns to that is used for promoting steering cylinder ejects, promote the left and right spindle arm of change speed gear box, realize machine and turn to the left or to the right.The present invention is simple for structure, and compactness is handled among a small circle to steering operation bar, just can realize machine and turn to; The present invention, by the work of control steering hydraulic valve of handling among a small circle of steering operation bar, therefore only needs very little power operation, reduces fatigue; The present invention promotes left and right spindle arm by fluid-link steering oil cylinder and realizes and turning to, and the connecting rod, the torque arm that reduce former mechanism connect the gap producing, and realize accurately and controlling, good reliability.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is front view of the present invention;
Fig. 2 is birds-eye view of the present invention (not comprising driver's seat);
Fig. 3 is steering operation schematic diagram of the present invention.
The specific embodiment:
Embodiment, is shown in accompanying drawing 1~3, and a kind of Light Crawler Tractor turns to control mechanism, comprises driving engine 1, change speed gear box 2 and master operating station 3, and driving engine and change speed gear box link together by power-transfer clutch; Described master operating station is positioned at engine right side, the upside of change speed gear box; One steering operation bar 4 is installed on described master operating station, and master operating station bottom is provided with a steering hydraulic valve 5, between steering operation bar and steering hydraulic valve, is connected a connecting rod 6; Steering cylinder 7 is housed on described change speed gear box, steering cylinder left end is connected with left and right steering oil pipe 8,9, in steering cylinder, be provided with the left and right push rod 10,11 that turns to, on change speed gear box, there is left and right spindle arm 12,13, left steering push rod can promote left steering arm and rotate, and right steering push rod can promote right steering arm and rotate; Described steering hydraulic valve is connected with steering cylinder by left and right steering oil pipe.
