Abstract
A miniature farmland tillage machine has an n-type chassis as the basis which has two reduction gearboxes combined with the two sides of a gearbox in inclined. Road wheels are arranged on the two sides of the reduction gearbox, and the centre of the chassis is provided with a central antiskid wheel. Due to the structure of the n-type chassis, the barycenter of the whole machine is at the nearest position to the road wheel. The balance and anti-subversion performance is improved. The central antiskid wheel can overcome the disadvantage of bigger angle of the tillage machine that the component force deviates from resultant force. The utility model has the advantages of flexible manipulation, stable working performance, strong adaptability, and can be widely used for the tillage of the paddy field and dry land in different areas.
Description
The utility model relates to a kind of balance, stablizes and resists overturns performance, especially can overcome component and depart from the miniature farming operation machine that resulatnt angle is spent big shortcoming.
The domestic duplicate rows travelling wheel small cultivator that generally uses, generally all adopt speed reduction gearing until final running part, merge the chassis structure form that is assembled in the casing, it is far away that the longitudinal center of gravity of complete machine departs from road wheel, tiltable gravity centre distribution angle is little, and center of gravity is then high, as Chinese patent application technology " the rack two-wheel drives small cultivator " (94229944.2), so the ploughing work at bigger slope and ridging is just had any problem, or make and cause the shortcoming of overturning; Again in small cultivator of the same type, the change speed gear box on chassis all is that the center that uprightly is arranged at road wheel is the basis, makes to cause the place ahead diesel engine weight and cross the obvious non-equilibrium state that is better than rear operating control and tillage implements weight.Duplicate rows travelling wheel small cultivator all has component to depart from resulatnt angle and spends big shortcoming simultaneously.And for example also there is the transaction capabilities instability " miniature walking tractor " (99245418.2) of Chinese patent application technology, handle difficulty and the high shortcoming of labour intensity.
The purpose of this utility model: provide a kind of not only have better balance performance and the anti-performance of overturning, and can also overcome component and depart from resulatnt angle and spend that the paddy field of big shortcoming, nonirrigated farmland all can farming, the miniature farming operation machine that transaction capabilities is stable, comformability is strong, operation is light.
The purpose of this utility model is achieved in that by a transmission assembly, two speed reducer assemblies, power-transfer clutch, gear-change hand lever, steering tiller, Oil Switch, two travelling wheels, a center anti sliding wheel, diesel engine, draw gear, frame supports and supporting tillage implements constitutes.
Diesel engine and frame are installed in the place ahead of change speed gear box, arm-rest frame is connected with the rear of change speed gear box, Oil Switch, clutch handle, steering tiller is installed on the arm-rest frame, gear-change hand lever is installed in the back upper place of change speed gear box, and road wheel is installed in the outside shaft extension position of the final transmission of two side speed reducers.Oil Switch links by the throttle of attaching parts and diesel engine.The back lower place that draw gear is arranged on change speed gear box articulates supporting tillage implements, and two speed reducer assembly inclined types are combined in the both sides of change speed gear box, keeps the balance of tiller.
Speed reduction gearing is incorporated into the both sides of change speed gear box respectively, can drop on the center of gravity of tiller by the nearest position of road wheel.The deadweight of speed reduction gearing, the while acts on the minimum position on chassis again.Reduce the center of gravity of tiller accordingly, improved the anti-performance of overturning.
The diameter of center anti sliding wheel is littler than the diameter of road wheel, cooperates with the right road wheel, becomes the manner of execution of staged anti sliding wheel.During when walking wheel clogging ditch or in the ploughing work of ridging and ploughing, the center anti sliding wheel can play important effect.For example: in cultivation operation, the right road wheel is walked under the ditch of ploughing, and the center anti sliding wheel is just in time walked on the ground of not ploughing.Because the application force of center anti sliding wheel is made a concerted effort in line near tiller, the component that has improved tiller departs from resulatnt angle and spends big phenomenon, has realized the purpose that transaction capabilities is stable.
Owing to adopted above-mentioned scheme, only be combined in the both sides of change speed gear box and the center anti sliding wheel be set speed reduction gearing is tilting, realized simply improving tiller balance quality, anti-ly overturn performance and improve component and depart from the shortcoming of making a concerted effort, be convenient to handle.
Below in conjunction with drawings and Examples the utility model is further described:
