Description

Light tillage machine

technical field

The utility model relates to an agricultural farming machine, in particular to a light tillage machine.

Background technique

As agricultural farming machinery, light tillage machines are mainly suitable for paddy fields, dry land, sloping land, vegetable fields and garden loosening soil in southern hilly areas. At present, light tillage machines mainly include rotary knife group drive type, front tillage rear drive type and chain side Three types of transmission. Rotary tiller group drive type: The working parts of the rotary tiller group are directly driven by the driving wheel shaft. It is characterized by simple structure and low price, but because there is no driving wheel and steering mechanism, the operation is laborious and the operator is labor-intensive. Front tillage and rear drive type: The rotary tiller is in the front and the drive wheel is in the back. It is difficult to control the tillage depth, and the rotary tiller is easy to drill into the soil and even turn off the fire. Chain side transmission type: The power output of the gearbox adopts chain side transmission, the structure is relatively loose, and the chain is easy to be stretched and broken. For this reason, many manufacturers and people of insight carry out development and trial production at the above-mentioned problem, but comparatively ideal product is not yet available so far. 

Contents of the invention

In order to overcome the above-mentioned deficiencies of existing light tillage machines, the purpose of this utility model is to provide a light tillage machine with simple and compact structure, stable transmission, small volume, light weight, light and flexible operation, and convenient control of tillage depth.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems includes a tail wheel assembly, a fender assembly, a left and right rotary tiller group, a coulter transmission box assembly, a connecting seat, a left and right driving wheel assembly, and a frame Assembly, clutch cover, diesel engine, clutch assembly, gearbox assembly, control mechanism assembly, the diesel engine is installed on the frame assembly, the clutch assembly is installed above the gearbox assembly, and the left and right drive wheel assemblies are installed correspondingly On both sides of the gearbox assembly, the left and right rotary tiller groups are correspondingly installed on both sides of the coulter transmission box assembly. After plowing, the gearbox assembly is tilted backward at a certain angle corresponding to the drive shaft. The gearbox assembly is connected to the coulter transmission box assembly through the connecting seat on the abdomen, and the gearbox assembly and the coulter transmission box assembly form a "△" shape. Solid structure.

The coulter transmission box assembly adopts two-stage spiral bevel gear direct transmission rotary tiller left and right rotary tiller groups.

After adopting the above structure, compared with the prior art, it has the following advantages or effects: First, due to the adoption of the structure of front drive and rear tillage, the work is stable, the operation is flexible, and the depth control is convenient. The second is that the gearbox assembly is connected with the coulter transmission box assembly through the connecting seat, and the coupling is fast and convenient. The third is to use two-stage spiral bevel gears to directly transmit the left and right rotary tiller groups of the rotary tiller, which has stable transmission, good reliability and long service life. Fourth, it has the advantages of compact structure, small size, light weight, light and flexible operation, etc.
