Automobile form harvester chasis

Abstract

The invention relates to a cropper chassis of a type similar to the type of an automobile, and is an agricultural machine. A majority of current cropper chassis have machines weighing on a driving wheel and an oversized pressure to the ground, thus being beneficial to the protection of the surface of the arable land; when a shift-region operation is carried out, as a directive wheel is not provided with a braking, the shift-region speed is limited, thus reducing the safety property of the braking. The invention provides a cropper chassis a type similar to the type of an automobile, and includes a machine frame, a driving axle, a directive axle, an engine, a gear-box, a transmission shaft, a reverse gear-box, a force obtaining device, a four-wheel braking system, and a damping flat spring. The whole chassis is a rear steering type, therefore the total weight is distributed equally to four tyres, and the pressure to the ground is greatly lowered; meanwhile, the adoption of the braking of the four wheels and the damping flat spring arranged on the directive axle assure safe and fast trans-regional work of the cropper.

Description

technical field [0001] The invention relates to a harvester chassis similar to that of a car, which is an agricultural machine. Background technique [0002] The current self-propelled harvester generally adopts a special chassis similar to that of a tractor. It is characterized in that the gearbox itself is used as the frame structure and assumes the function of the drive axle. Steering wheels only carry a fraction of the weight of the car body, and almost the entire weight of the car is placed on the driving wheels. This design is actually developed from a tractor, and its purpose is to provide a strong traction ability for towing operations. However, after being transplanted to harvesting machinery, some disadvantages appear, mainly including: most of the weight of the vehicle body is carried by the driving wheel, and the pressure on the ground is too large, which is not conducive to the protection of the cultivated land surface; Traction, so the ability to grip the gro...

Problems solved by technology

However, after being transplanted to harvesting machinery, some disadvantages appear, mainly including: most of the weight of the vehicle body is carried by the driving wheel, and the pressure on the ground is too large, which is not conducive to the protection of the cultivated land surface; Traction, so the ability to grip the ground is no longer emphasized; during the transfer operation, because the steering wheel has no brakes, the speed limit cannot be too fast, which affects the transfer speed and braking safety performance of the harvester
