Abstract
The invention discloses a liftable walking tractor, which comprises a rack, a diesel engine, a clutch, a speed changing box and a hydraulic lift. A left hydrocylinder and a right hydrocylinder on the hydraulic lift stretch out and draw back simultaneously, or the left hydrocylinder stretches out and the right hydrocylinder draws back or the right hydrocylinder stretches out and the left hydrocylinder draws back, and therefore, optional lifting of left and right driving wheels of the tractor is realized; when the liftable walking tractor works in a hilly land, the height of the left and right driving wheels can be adjusted according to the slope, so that a tractor body keeps steady all along and cannot incline or roll over; moreover, the liftable walking tractor is strong in transmitted power and is safe and reliable.
Description
Technical field
The present invention relates to a kind of walker tractor, relate in particular to a kind of liftable walker tractor of applicable hillside operation.
Background technology
As everyone knows, walker tractor is small-sized with it, and flexible operation has become China's vast rural area short-distance transport, plough, and the main agricultural machinery and implement that water.But present walker tractor is due on left and right sidesing driving wheel is fixed on same axis, can not adjust along with the slope change of walking region the height of its left and right sidesing driving wheel, while laterally walking in hillside fields, easily turn on one's side, only suitable on level land or the less hillside fields operation of the gradient, and can not be applied to the area, Huo Qiu ridge, mountain region that the gradient is larger.For addressing this problem, someone has developed the walker tractor that a kind of applicable hillside is used, this hillside walker tractor comprises frame, diesel motor, power-transfer clutch, change speed gear box, jacking system, operating mechanism etc., the lift arm wherein playing a major role in jacking system is by chain transferring power, be that lift arm is provided with lower supporting plate between the transition axis with routine and output shaft, and pass through chain transmission between the transition axis in homonymy and output shaft; Two drive wheels of trac. are arranged on respectively on two output shafts.Once chain is aging or fracture can make walker tractor overturn, and causes serious consequence.
Summary of the invention
The object of the invention is the problem existing when the hillside operation for existing walker tractor, provide a kind of can be according to gradient size, regulate left and right sidesing driving wheel height, make tractor body remain steady, be unlikely inclination, rollover, and also transferring power is large, safe and reliable, the walker tractor of applicable hillside operation simple in structure.
The object of the invention is to be achieved through the following technical solutions, this liftable walker tractor comprises frame, diesel motor, power-transfer clutch, change speed gear box, hydraulic lift.
Described diesel motor is fixed in frame, and described diesel engine is provided with power-transfer clutch, and power-transfer clutch is connected with change speed gear box.
Described hydraulic lift comprises left and right hydraulic ram, lift arm, hydraulic oil pump, Multi-path distribution valve, described change speed gear box is connected with one end of left and right lift arm by change speed gear box main driving axle, the other end of left and right lift arm is connected with the lower end of left and right hydraulic ram by jack shaft, the upper end of left and right hydraulic ram is fixed on hydraulic ram support, hydraulic oil pump is connected to hydraulic reservoir by oil inlet, the other end is connected to multipath hydraulic distributing valve, multipath hydraulic distributing valve is connected respectively to entering of left and right hydraulic ram with four hydraulic oil pipes, oil out port, on semiaxis, by wheel hub, connect tire.
A deceleration semiaxis stretches out outside body in described change speed gear box, the outer belt pulley of fixing, by belt pulley by transmission of power to hydraulic oil pump.
Described left and right lift arm is an oblong housing, in described oblong housing, be provided with successively respectively the transmission shaft being connected with output shaft of gear-box, one, two, three gear wheel shaft and jack shaft, described transmission shaft, on one, two, three gear wheel shaft and jack shaft, be equipped with can be mutually meshing gear successively.
Beneficial effect of the present invention: owing to adopting said structure, regulate left and right sidesing driving wheel height by hydraulic lift, tractor body is remained steadily, be unlikely inclination, to adapt to the needs of different hillside operations.

In figure: 1, frame 2, diesel motor 3, power-transfer clutch 4, change speed gear box 5, hydraulic lift 6, left and right hydraulic ram 7, lift arm 8, hydraulic oil pump 9, Multi-path distribution valve 10, oblong housing 11, transmission shaft 12, the first gear wheel shaft 13, the second gear wheel shaft 14, the 3rd gear wheel shaft 15, jack shaft 16, change speed gear box main driving axle 17, joystick
The specific embodiment
As shown in Figure 1, 2, 3, this hillside walker tractor comprises frame 1, diesel motor 2, power-transfer clutch 3, change speed gear box 4, hydraulic lift 5, and diesel motor 2 is fixed in frame 1, and diesel engine 2 is provided with power-transfer clutch 3, and power-transfer clutch 3 is connected with change speed gear box 4.
The power of diesel motor 2 outputs is delivered to change speed gear box 4 via power-transfer clutch 3, the power driven left and right lift arm 7 that change speed gear box 4 is exported by main driving axle 16, in left and right lift arm 7, pass through transmission shaft 11, the engagement commutation of the gear on one, two, three gear wheel shaft 12,13,14 and jack shaft 15 to jack shaft 15, connects transmission of power tire by wheel hub on jack shaft 15 and realizes the whole walking process of trac. that turned round.
The transmission of power that change speed gear box 4 is exported by the belt pulley on deceleration semiaxis is to hydraulic oil pump 8, hydraulic oil pump 8 is connected to hydraulic reservoir by oil inlet, the other end is connected to multipath hydraulic distributing valve 9, and four hydraulic oil pipes of multipath hydraulic distributing valve 9 use are connected respectively to the entering of left and right hydraulic ram 6, oil return interface.By two joysticks 17 of M/C Multi-path distribution valve 9, realize stretching or contracting of left and right hydraulic ram.Joystick can single operation, also can operate simultaneously, completes that left and right hydraulic ram simultaneous retractable, a left side are stretched right contracting, left contracting is stretched on the right side, to realize the random lifting of trac. left and right wheels.
On-the-ground test proves: during farm work, by two joysticks 17 of manual control Multi-path distribution valve 9, make left and right hydraulic ram 6 stretched lift arm 7 rising and decline and to adjust inclination (the left and right lifting simultaneously of body, also can one rising one falls, can also motionless another liter or fall), thereby realized the inclination of walker tractor, before and after body, center-of-gravity position remains unchanged like this, makes the balance that remains of whole body.Guarantee the balance work of hillside walker tractor on the following slope land of 22.5 degree.Common walker tractor is greater than the slope land of 15 degree just can not normally cultivate the work of sprinkling irrigation laxative, the slope land that is greater than 30 degree will overturn, hillside walker tractor has not only met the job requirements of common walker tractor, can also normally cosily complete transportation and operation at the following slope land of 22.5 degree, slope land can not overturn at 35 degree.Various farm work adaptednesses improve greatly, and economic benefit and social benefit are very remarkable.
