Paddy field wheeled tractor

Abstract

The invention relates to a paddy field wheeled tractor which comprises a power system assembly, a walking system assembly, a transmission system assembly, a covering part assembly, a steering system assembly, a hydraulic system assembly and a rear working device. The transmission system assembly serves as the basis of the whole tractor. The power system assembly, the walking system assembly, the covering part assembly, the steering system assembly, the hydraulic system assembly and the rear working device are directly or indirectly connected with the transmission system assembly. By optimizingthe structural layout, the front wheel steering angle is increased, the turning radius of the whole machine is reduced, the ground clearance of the whole machine is increased, and the mass of the whole machine is reduced, so that the tractor has good trafficability in a paddy field, and the requirements of the national IV emission standard are met.

Description

technical field [0001] The invention belongs to the field of tractors, in particular to a paddy field wheeled tractor. Background technique [0002] Most of the wheeled tractors currently used in paddy fields in our country are tractors mainly for dry land operations or tractors for both water and dry operations, which are partially improved by being equipped with paddy field tires. There are many problems in the adaptability and reliability of the operation, such as heavy weight of the whole machine, large turning radius, large grounding specific pressure, great damage to the hard bottom of paddy fields, and inability to adapt to muddy fields with low bearing pressure. There are obvious deficiencies in sealing protection, anti-grass and mud, anti-corrosion and anti-rust, paddy field passability, mobility, and ergonomic manipulation comfort. Moreover, after the emission is upgraded according to the requirements of environmental protection regulations, the original layout an...

Problems solved by technology

[0002] Most of the wheeled tractors currently used in paddy fields in our country are tractors mainly for dry land operations or tractors for both water and dry operations, which are partially improved by being equipped with paddy field tires. There are many problems in the adaptability and reliability of the operation, such as the heavy weight of the whole machine, the large turning radius, the large grounding specific pressure, the large damage to the hard bottom of the paddy field, and the inability to adapt to the muddy field with low bearing pressure. There are obvious deficiencies in sealing protection, anti-grass and mud, anti-corrosion and anti-rust, paddy field passability, mobility, and ergonomic manipulation comfort.

And according to the requirements of environmental protection laws and regulations, after the emission is upgraded, the original layout and structure of the whole machine can no longer meet the requirements of the latest national emission standards.
