Description
Technical field:
The utility model relates to agricultural machinery technological field, relates to a kind of Light Crawler Tractor course changing control mechanism in particular.
Background technology:
The left and right turn of current domestic common Light Crawler Tractor is handled and is mainly contained two kinds of structures: 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 that structure is simple, easily manufactured, cost is low; Shortcoming is rustic, especially draw change hands handle time stroke large, have interference with operator from health.The second operator's station is provided with bearing circle, steering wheel rotation, and under driving, pivoted arm rotates, and pulls spindle arm on change speed gear box to rotate, realize turning to of machine by cylinder lever connecting rod, and its advantage controls to turn to bearing circle, and compact structure is attractive in appearance; Shortcoming is that rotating of steering wheel drives pivoted arm to pull and turn to, and bearing circle resistance is large, and operation turns to requires great effort very much, and long-time operation is easily tired.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, and provide a kind of Light Crawler Tractor course changing control mechanism, it is simple for structure, suitable Light Crawler Tractor structure space, easy and simple to handle, practical reliable.
Technology solution of the present utility model is as follows:
A kind of Light Crawler Tractor course changing control mechanism, comprise driving engine, change speed gear box and master operating station, 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; Described master operating station is provided with a steering operation bar, a steering hydraulic valve is installed bottom master operating station, steering operation bar be connected a connecting rod between steering hydraulic valve; Described change speed gear box is equipped with steering cylinder, steering cylinder left end is connected with left and right steering oil pipe, is provided with left and rightly to turn to push rod in steering cylinder, change speed gear box has left and right spindle arm, 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.
Described steering operation bar promotes the valve rod of steering hydraulic valve by connecting rod and 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 and makes it turn 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 turn to the left or to the right.
As preferably, described master operating station is provided with driver's seat.
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.
The beneficial effects of the utility model are:
During utility model works, promote steering operation bar to the left or to the right, the left and right steering oil pipe controlling steering hydraulic valve is fuel-displaced, and the left and right push rod that turns to being 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 utility model is simple for structure, compact, handles among a small circle steering operation bar, just can realize machine and turn to; The utility model, by the work of the steering hydraulic valve of maneuvering and control among a small circle of steering operation bar, therefore only needs very little power operation, reduces tired; The utility model promotes left and right spindle arm to realize to turn to by fluid-link steering oil cylinder, reduces the connecting rod of former mechanism, torque arm connects the gap produced, and realizes accurately controlling, good reliability.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model (not comprising driver's seat);
Fig. 3 is steering operation schematic diagram of the present utility model.
Detailed description of the invention:
Embodiment, is shown in accompanying drawing 1 ~ 3, a kind of Light Crawler Tractor course changing control mechanism, and comprise driving engine 1, change speed gear box 2 and master operating station 3, driving engine and change speed gear box are linked together by power-transfer clutch; Described master operating station is positioned at engine right side, the upside of change speed gear box; Described master operating station is provided with a steering operation bar 4, a steering hydraulic valve 5 is installed bottom master operating station, steering operation bar be connected a connecting rod 6 between steering hydraulic valve; Steering cylinder 7 described change speed gear box is equipped with, steering cylinder left end is connected with left and right steering oil pipe 8,9, be provided with in steering cylinder and left and rightly turn to push rod 10,11, 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.
Described master operating station is provided with driver's seat 14, is convenient to chaufeur and uses operation trac..
The upper end of described steering operation bar is provided with a lever, is convenient to user and holds to handle steering operation bar and turn to the left or to the right, by the work of the steering hydraulic valve of maneuvering and control among a small circle of steering operation bar, therefore only needs very little power operation, reduces tired.
Utility model works principle: during work, promoting steering operation bar to the left or to the right makes it turn to, the valve rod that steering operation bar promotes steering hydraulic valve by connecting rod turns to fuel-displaced to the left or to the right, by left-handed turning to fuel-displaced, the left steering push rod that can promote steering cylinder ejects and promotes left steering arm and makes it turn 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.
