Description

A kind of hillside fields self-propelled mower

Technical field

The utility model relates to a kind of mower, is to be particularly suitable for the novel mowing machinery of the gradient in mountain region below 30 ° and the mowing of ramp field.

Background technology

At present, the mower kind is many on the market, can be divided into rotaryly and reciprocating type from cutter form, divides from function to be divided into herbage mower and hay mower etc.Rotary mower speed is fast, efficient is high, and be fit to very much large tracts of land and mow, but because its center of gravity height, structure is huge, and at the narrow and small hillside of area, Yin Qiyi tumbles, difficult tune, and price is higher, is difficult in poor mountain area promote; Shuttle low mower center of gravity low (except the tractor supporting) with it, energy consumption is little, and is cheap, but because ground, mountain area is to be uneven, and the peasant require to cut the stubble low more good more, can overcharge a little herbages for such one batch, therefore, shuttle low mower in this case, cutter contacts with earth, even can often cut earth, uses the cutter life-span very short in the mountain area, the use cost of mower is increased greatly, increased the weight of peasant's burden; Though vertical shaft type hay mower center of gravity is low, and is in light weight,, there are three fatal shortcomings equally: dishing out after the grass chopping, be not easy to reclaim and the airing storage when 1, mowing; 2, the road wheel diameter is little, and trafficability characteristic is poor, is not suitable for rugged hillside and uses; 3, function singleness only can be used for mowing.

Summary of the invention

The technical problems to be solved in the utility model is to overcome shortcoming that above-mentioned mower exists and the restriction on application and the function, the mower that provides a kind of suitable hillside fields to use, this machine compact conformation, in light weight, center of gravity is low, adaptability is strong.

For solving the problems of the technologies described above, the utility model comprises frame, rack-mounted road wheel, be arranged on the power source on the described frame, the reducing gear that connects power source and road wheel is installed on the frame, be installed in frame front and by the grass cutter assembly of described drive power source, its design feature is that the operation handrail is installed on reducing gear, operating mechanism is installed on the handrail, and described grass cutter assembly is hinged on the frame, is provided with adjusting yoke between frame and grass cutter assembly top.

As to improvement of the present utility model, described reducing gear comprises gearbox and the planet gear speed reducer with small tooth difference that is connected as a single entity with it.

As to further improvement of the utility model, be movably installed with parking bracket at the rear portion of frame; The careless protector of branch is installed on the grass cutter assembly.

Described grass cutter assembly comprises transmission case, and transmission case is provided with power input pulley, and tumbler gear, cutter shaft are installed in the transmission case, and the bottom of cutter shaft is equipped with cutterhead, and cutter is installed on the cutterhead, on the bottom surface of cutterhead sliding plate is installed.

After adopting said structure, this machine compact conformation, in light weight, center of gravity is low, adaptability is strong, because the grass cutter assembly is hinged on the frame, between frame and grass cutter assembly top, be provided with adjusting yoke, thereby make the height of mowing dish, mowing inclination angle arbitrarily to adjust as required, be particularly suitable for the gradient and mow in mountain region below 30 ° and ramp field.By supporting corresponding work tool, no matter also can finish operations such as arable land, rotary tillage, sowing, intertillage, fertilising, be that cutterbar attachment is mowed, still supporting other farm machinery, its length and width can not surpass a head of cattle, and it highly is less than farm cattle height half.Owing in gearbox transmission design, adopted the small teeth number difference planet gear transmission, because its gearratio is bigger, therefore, can significantly reduce gear-driven progression, minimum as long as the transmission of one-level small teeth number difference planet gear, one-level gear drive and the transmission of one-level V-belt just can make gearratio reach 200, guaranteed that fundamentally the compactness of complete machine structure is with rationally.This machine also can be used as the horticultural management machine and uses.
