Three, summary of the invention

The purpose of this utility model provide a kind of simple in structure, small and exquisite flexibly, turn radius is little, center of gravity is low, sit the three-wheel tractor of driving comfortable, high efficiency, a tractor serves several purposes.

The technical solution adopted in the utility model is: three-wheel tractor two trailing wheels are indifferential device drive wheel, and a front-wheel is a track adjusting wheel, and three wheels are equilateral triangle and arrange; Diesel engine is between track adjusting wheel and drive wheel, and seat is on diesel engine; Diesel engine drives trailing wheel by V-wheel drive through selector gear and rotates.Personnel are sitting in the diesel oil hands-operation, can increase propulsive effort.

Steering hardware of the present utility model adopts steering handle, and manual clutch is arranged on the steering handle.

The utility model also is furnished with several secondary machines, comprises the two ridges of the hydraulic lifting slag machine that goes out, and this slag machine that goes out adopts coaxial hydraulic lifting technology, hang over the rear portion of main frame, by the hydraulic pressure adjustment slag degree of depth of going out, because the slag machine postposition of going out, thereby improve the working environment of operating personal greatly, reduce labour intensity.

Hydraulic lifting three ploughshare ridgers are held concurrently and are breathed out the paddy field, and three ploughshares are isosceles triangle immediately following three wheels and arrange.Immediately following ploughshare of front jockey wheel, no matter the condition profiling effect that just rises and falls is better for this ploughshare, the ridge depth unanimity of being up to, it is on the square sliding sleeve that latter two ploughshare is fixed on two endoporus, sliding sleeve is enclosed within on the horizontal square shaft and can horizontally slips along square shaft, horizontal square shaft is fixed on the tailstock, and tailstock is tight because of on the change speed gear box back cover by bolt.On horizontal sliding sleeve, also fix a vertical sliding sleeve, in sliding iron is arranged, sliding iron lower end is ploughshare and play with hydraulic ram fixedly, by flexible rising and falling of ploughshare, the adjustment depth of reaching of hydraulic actuating cylinder.Latter two ploughshare each has the cylinder of oneself, and is independent separately, can adapt to the remote land on slope condition like this.Unload two ploughshares, change ocean plough (paddy field plough) and can enter paddy-field-working.

The hydraulic lifting raker, unload the ocean plough on latter two hydraulic actuating cylinder, hydraulic actuating cylinder is divided right and left along horizontal square shaft, then the paddy field rake is hung up, again rubber tire is changed the roller of raking the soil level, just can harrow the paddy field, the bulk lump of earth rolls rake with raking the soil level broken, harrows into sposh, hug with the rake of back then, but this rake is by hydraulic actuating cylinder furnishing level, and is also can the high end of furnishing one end low, thus the paddy field level of hugging in order to rice transplanting.
