Description

The high-mobility, multipurpose, wheeled vehicle trac. of bowing

Technical field

The utility model relates to a kind of farm machinery, especially a kind of high-mobility, multipurpose, wheeled vehicle trac. of bowing.

Background technology

Farm tractor generally is divided into two kinds at present: walker tractor and bearing circle trac..

Walker tractor is that a kind of small-sized bowing is trac., by driving engine, and the machinery that chassis, system such as electric form; The power that leans on combustion engine is through driving system, and the drive wheel that obtains driving torque is given little, the horizontal applied force backward (circumferential force) in ground through tire tread and surface of tyre again, and is simple in structure; Power is less; Plug-in plow harrow is suitable for fritter and ploughs, and is being held up arm-rest frame control steering unit, traction or is being driven matched farm tool by chaufeur and carrying out operation; Its bearing circle generally adopts U type hand-held type, adopts pinching linking to each other with the direction machine through push-and-pull rod on the hand steered bearing circle, and braking is service brake; Can be used to the level land of ploughing; But be unfavorable for transportation, when running into rough road conditions, the stressed back swing of hand steered bearing circle is big; Easily the people is thrown away operator's compartment, safety is not high.

The bearing circle trac. adopts the circular direction dish that is similar to automobile; Through cw or the control of left-hand revolution bearing circle travel direction, generally adopt four wheel drive, band compartment, back can be used for shipping goods; Hill climbing ability is strong; But when meeting rough road, the stressed back of wheel drives bearing circle and rotates rapidly, easily the hired roughneck; And can not be used for ploughing.

Summary of the invention

The purpose of the utility model is a kind of safe in utilization, bearing circle will be provided hired roughneck, hill climbing ability by force, not only not can be used for ploughing but also the high-mobility, multipurpose, wheeled vehicle that can be used for the transporting trac. of bowing.

The utility model is achieved in that the high-mobility, multipurpose, wheeled vehicle trac. of bowing; Comprise headstock, wheel, direction control mechanism, pull parts and brake system; Said headstock rear end is provided with change speed gear box and traction frame, it is characterized in that said direction control mechanism adopts the yi word pattern hand-held type, and its yi word pattern bearing circle right ends is provided with pinches handle; Said pinching linking to each other with the shift fork that turns to of change speed gear box through flexible directional line, direction control mechanism and direction pull bar junction are provided with the direction retarder; Said traction frame is a rotational coupling mechanism; One end is connected through screw retention with change speed gear box, and the other end is provided with connecting bore and latch, and the said parts of pulling are operator's compartment compartment or plow harrow; Said operator's compartment compartment is connected with change speed gear box through traction frame, and said plow harrow is connected with change speed gear box through screw.

The utility model is actually two kinds of trac.s in the routine techniques is combined, and makes and optimize improvement: with the headstock of walker tractor, mix the operator's compartment compartment of bearing circle trac., can carry out hauling operation; If be unworthy of the operator's compartment compartment, then mix hand steered of plow harrow and can plough and level land.Like this, in conjunction with before the advantage of two kinds of trac.s, both safety, hired roughneck not can transport again, hill climbing ability is strong, also can be used for the level land of ploughing, and is a kind of multi-functional farm tractor.

Achieve the above object; Key is the improvement of direct system: traction frame is connected through screw retention with change speed gear box; Traction frame is designed to rotatable detouchable bolt-type to be connected; One end is fixed on the traction frame place (the conventional place that links to each other with plow harrow) of headstock afterbody, and the other end and operator's compartment compartment or plow harrow are fixedly linked; Connect through traction frame between the two ends.When being used to transport, the connecting portion and the traction frame of compartment one end being agreed with, and latch is installed is got final product; When being used to plough, take out the screw of traction frame, unload traction frame, the connecting portion and the change speed gear box of plow harrow one end agreed with, and mounting screw gets final product.Be provided with connecting bore on the connecting portion of said compartment or plow harrow one end, also connecting bore on the traction frame or the screw on the change speed gear box are complementary; Concrete connection mode can adopt any connection mode of the prior art, agrees with like the U type etc.Bearing circle adopts the yi word pattern handlebar, is similar to the direction handlebar of motor bike.It is pinched being similar to the parking brake of motor bike, but does not have brake function, only is used to control direction, through about pinch pinch and put, realize swinging of headstock.Pinch linking to each other with turning to shift fork through flexible directional line, this just is different from being connected of traditional rigid pull bar and direction machine.Simultaneously, bearing circle strut bar and direction pull bar junction are provided with the direction retarder reducing gear of pinion drive big gear wheel (promptly with), and headstock is done when swinging significantly, and bearing circle is only done swing by a small margin.Have on the road surface when concavo-convex, wheel receives the power of compeling to drive the direction handlebar to swing when big, and traditional walker tractor throws away the people easily; This type of potential safety hazard has then been avoided in the existence of flexible directional line and retarder.

In addition, the direction handlebar adopts yi word pattern, has avoided the wheel slipping situation of conventional direction dish trac..When conventional direction dish trac. went on uneven road surface, the pressure soil fertility that four-wheel bears was different, caused and pressed the big wheel of soil fertility not change, and press the little wheel slipping of soil fertility, had influenced the ability of advancing and hill climbing ability.And the wheel of yi word pattern hand-held type has stronger comformability no matter the still light ground of pressing, weight ground all can rotate to uneven not road surface.

The utility model adopts four wheel drive (being two-wheeled during cultivated land): front-wheel adopts machinery to stop; Trailing wheel adopts gas to stop during transportation.The cooperation of these two kinds of brake system, make go safer more stable.

In sum, the utility model is that hired roughneck, hill climbing ability by force, not only not can be used for ploughing but also the high-mobility, multipurpose, wheeled vehicle that can be used for the transporting trac. of bowing a kind of safe in utilization, bearing circle.
