Abstract

The utility model belongs to a hand truck among agricultural transport machines. The hand truck comprises a frame, supporting legs, a left armrest, a right armrest, and three wheels equipped on a surface vertical to a symmetrical axle of the truck body. Two wheels are main wheels and one wheel is a transition wheel equipped at a front end. When the truck operates on a normal surface, the transition wheel does not work. But in case of a gully, the directional wheel will work with a rear wheel and a middle wheel to enable the middle wheel and the rear wheel to get across the gully smoothly and steadily. Thus, the truck is characterized in that the truck is capable of moving on a path or a low farmland bank with gullies smoothly and steadily and is provided with strong applicability and a wide applicable scope for road surfaces, which overcomes a defect that a traditional wheelbarrow fails to move on a path with gullies.

Description

A kind of agricultural hand barrow

Technical field

The utility model belongs to the hand barrow in a kind of agricultural manpower Transport Machinery, particularly a kind of hand barrow that is provided with three wheels on the vertical plane of symmetry of car body.It is uneven and the usefulness that conveys goods on the raised path through fields, path in the gully of pouring water etc. arranged that this hand barrow is particluarly suitable for the rural area.

Background technology

Conventional rural area is used to push the wheel barrow of grain, goods, its structure comprises vehicle frame, the support foot of two handrails (car thick stick) about a wheel and band, wheel is located on the vertical plane of symmetry of vehicle frame, the operator holds handrail with two vehicle frame is lifted, firmly carries out forward behind the support foot built on stilts during operation, thereby will place goods on the vehicle frame etc. to transport to the destination.This type of wheelbarrow is owing to have only a wheel, during work by human body be used as power, by two arm balance plays, thereby have easy to usely, flexibly, generally on very narrow trail, rural area, the raised path through fields, need only no gully and all can use.Therefore, still be subjected to the welcome in quite a few rural area so far.But just because of this car only has a wheel, (when irrigating breach etc. as having dug on the raised path through fields) is just can't pass through when running into the gully.Thereby this type of go-cart exists in the disadvantages such as (uses) of cannot travelling on the road in gully.

Summary of the invention

The purpose of this utility model is on the basis of wheel barrow, improve a kind of agricultural hand barrow of design, this hand barrow is keeping on the characteristics basis of former single-wheel barrow, also can travel smoothly having on the path in gully, the raised path through fields, with purposes such as the applicable area that improves its road pavement situation and abilities.

Solution of the present utility model is with the vehicle frame proper extension, and on the vertical plane of symmetry of car body, set up two wheels, one of them wheel and former wheel are main wheel, another is a transition wheel, transition wheel when normal road traveling, do not work (not in contact with the ground), and when meeting the gully, at first cross the gully, the main wheel of waiting to be positioned at the middle part enters top, gully when unsettled, filtering wheel then contacts the road surface on ditch opposite and bears the weight of whole locomotive body together with goods with back one main wheel, and advance forward, when the main wheel at middle part is crossed the gully then a main wheel is unsettled, then as wheelbarrow, play supporting and the effect of advancing by the main wheel in middle part, main wheel is crossed the gully until the back, thereby realizes its purpose.Therefore, the utility model comprises wheel, place the vehicle frame on the wheel and be located at the left and right handrail of vehicle frame rear end, the vehicle frame support foot; Key is that this hand barrow has three wheels, and three wheels all are located on the vertical plane of symmetry of car body, and wherein two is main wheel, and one is track adjusting wheel, and track adjusting wheel is located at the front end of support body bottom and two main wheels; Each wheel is by wheel shaft and corresponding wheel support plate and the fastening one that is connected into of vehicle frame, then connects turnably by bearing between wheel and the wheel shaft.Two wheels that main wheel is a same diameter in above-mentioned three wheels, track adjusting wheel then are the less wheel of diameter.

The utility model is owing to set up a main wheel and a transition wheel on the wheelbarrow basis, this go-cart is advanced on the road surface that can be no more than the 0.5m gully under the combined action of two main wheels and a transition wheel smoothly, reposefully.Thereby the utlity model has and can smooth-ride on the path in gully, the raised path through fields arranged, characteristics such as the adaptive capacity of road pavement is strong, applied widely.
