Description

The single wheel tiller of universal driving wheel

The utility model relates to a kind of agricultural machinery, especially a kind of single wheel tiller of universal driving wheel.

In disclosed document, tractor, harvesting and tillage machine, single wheel tiller etc., the wheel rim of driving wheel only plays the effect of one-sided bearing strength; Rim has certain distance from the maximum outside diameter of driving wheel.Limit the degree that rim contacts to earth, restricted the characteristic that cut in steady rolling and garden.The track of its rut does not have regeneration to get up to improve farming efficient at all.Therefore, though anti-skidding iron tyre traction adhesion property is good, it is poor to drive stationarity; It is steadily good that tire drives, but to soil compaction, to harden, draw tack poor.So this driving wheel of two types versatility in the soil relief of complexity is poor.This gives various tractor-ploughing mechanical structures, operates and raise the efficiency to bring inconvenience.For example: Chinese patent ZL96205927.7 discloses a kind of " single wheel tiller " ploughshare and has put before driving wheel, except that above-mentioned weak point is arranged, and the balance weight is set, increase added burden, the directly exposed interlock of driving wheel and driving cog, accelerated wear test easily, it is poor to drive stationarity.Operating period is short, mechanical efficiency is low, the rural area is difficult to promote.

The purpose of this utility model, be to overcome the above deficiency, the advantage separately of the driving wheel of comprehensive tire and anti-skidding iron tyre combines together, and provide simple in structure, volume is little, stable working is reliable, the single wheel tiller of a kind of universal driving wheel easy to use, the structural formula of its universal driving wheel can be done the driving wheel utilization at various tractor-ploughing machinery.

Concrete scheme of the present utility model is: diesel engine is contained in the housing, and an end that is arranged in the shaped as frame frame is characterized in that being equipped with an end of the axle of universal driving wheel, is provided with driven sprocket, and is installed on together in the frame shaped as frame; Gearbox is provided with clutch assembly, selector, and be connected with arm-rest frame, the middle part of being born perpendicular to the shaped as frame frame by support connects.Thereby, simplified the center of gravity problem that the utility model does not need balance.The output shaft of gearbox is provided with drive sprocket, connects with chain with driven sprocket on the universal live axle, loads onto enclosed chain cover, and power speed changing is transmitted in dustless anhydrous enclosed even running.Prolonged mechanical service life.The center of shaped as frame frame end connects ploughs the plough device, and diesel engine is starting in a single day, and power is through transmission system, and the people is holding up arm-rest frame just can work.

Above-mentioned universal driving wheel is arranged in the front end of ploughing the plough device, so its architectural feature equidistantly being connected along annular rim respectively by the several piece antiskid blade together at two thin type rims.And antiskid blade and rim external diameter and exceed the external diameter of rim together or not or the attached method of three kinds of modes such as little super external diameter, optional wherein a kind of mode, the width of the universal driving wheel that constitutes is this maneuver plough device one ploughshare field wide cut, and its version such as hollow garden cartridge type are rolled cage.Its universal driving wheel bearing strength is big, and self-cleaning is good, relies on mechanical gravity and mechanomotive force, and rim and antiskid blade are done the crosscut of continual vertical rolling cut and interruption, have reduced the resistance intensity in ploughshare front end field, so that plough the plough device along the operation of rut track.

It is simple in structure for the utility model, volume is little, easily makes, and need not counterweigh, and the power speed changing transmission is closed.The structural formula of its driving wheel, two types advantage separately of the driving wheel of collection tire and anti-skidding iron tyre combines together, promptly drive steadily, the traction tack is strong, and self-cleaning is good, have loose to the field of hardening, the regeneration of rut track is given full play in broken effect, improves tractor-ploughing efficient, and can replace tire driving effect stably, make the driving wheel highly versatile at various tractor-ploughing machinery.The utility model can be done the equally steady rolling transfer of single-wheel go-cart 20 centimeters wide narrow field bund or path one people in no mechanomotive force.Mixing thresher, grain header, combined seed and fertilizer drill can make Multi Role Aircraft and use.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the universal driving wheel symmetrical structure schematic diagram in the utility model.

Fig. 3 is first kind of structural formula among Fig. 2, rim and antiskid blade and neat symmetrical internal organs view.

Fig. 4 is second kind of structural formula among Fig. 2, the symmetrical internal organs view of the not super rim external diameter of antiskid blade.

Fig. 5 is the third structural formula among Fig. 2, the symmetrical internal organs view of the little super rim external diameter of antiskid blade.

By above-mentioned accompanying drawing as can be known: the utility model is equipped with diesel engine (1) by housing and links with shaped as frame frame (2) one ends, gearbox (3) links with arm-rest frame (6), the middle part of being born perpendicular to shaped as frame frame (2) by support (4) links, and gearbox (3) is provided with clutch (12), selector (13); The output the tip of the axis is provided with drive sprocket (9), and an end is provided with driven sprocket (10) etc. and is installed in together in the shaped as frame frame (2) on universal driving wheel (5) and the driving shaft.Chain connects drive sprocket (9) and driven sprocket (10) respectively in the chain cover (11); Universal driving wheel (5) is made up of several piece antiskid blade (7) between two rims (8).

By Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known: antiskid blade (7) can have three kinds of structural formulas with rim (8).A kind of is that antiskid blade (7) is also neat with the external diameter of rim (8); Two kinds is the not super rim of antiskid blade (7) (8) external diameter; Three kinds is the little super rim external diameter of antiskid blade (7).Optional wherein a kind of universal driving wheel of structural formula, in the shaped as frame frame of packing into (2), the terminal centre of shaped as frame frame (2) connects ploughs plough device (14).
