Crawler tractor for paddy field

Abstract

Provided is a crawler tractor for a paddy field. The crawler tractor comprises a frame, a perching knife device, a covering part assembly, a power device and accessories, a steering, braking and operating mechanism, a hydraulic system and a working device, a power transmission device and a walking mechanism; the frame is a basis of the whole crawler tractor, and a perching knife arm support of the perching knife device is fixed to a perching knife installing support of the frame; the covering part assembly is fixed to rear bottom plate installing support frames and front bottom plate installing support frames of the frame separately; an engine assembly of the power device and the accessories is fixed to an engine installing support arranged in the middle of a longitudinal beam of the frame; the steering, braking and operating mechanism and pedals are fixed to the covering part assembly separately; a gear pump of the hydraulic system and work device is connected to the engine assembly, a suspension rod part arranged at the rear end is connected to a suspension installing plate, and the hydraulic system and the working device are connected through a suspension oil cylinder oil pipe; a clutch shell of the power transmission device is connected to the engine assembly, and the rear end of the power transmission device is connected to the frame through a speed changing box support; a wheel train of the walking mechanism is fixed to the frame.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to an agricultural crawler-type walking device, in particular to a multifunctional paddy field crawler tractor capable of bulldozing at the front end, rotary tillage and ridging at the rear end, and traction and transportation operations . Background technique [0002] At present, my country's paddy field operations only have a relatively high degree of mechanization for sowing and harvesting, and the bottleneck of paddy field operations lies in farming. At present, most of the rural areas in my country basically use walking tractor rotary tillage, animal power or wheeled tractors for operations. Walking tractors or animal power farming have low work efficiency and high labor intensity; if large and medium-sized wheeled tractors are used continuously for farming with rotary tillers, the mud foot of the paddy field will be further deepened, which will bring further difficulties t...

AI Technical Summary

Problems solved by technology

Walking tractors or animal-powered farming have low work efficiency and high labor intensity; if large and medium-sized wheeled tractors are used continuously for farming with rotary tillers, the mud foot of the paddy field will be further deepened, which will bring further difficulties to the next operation of the paddy field

Most domestic paddy field farming machines borrow the structure of the harvester and are not developed according to the needs of paddy field farming. Therefore, there are the following problems: simple appearance, poor handling comfort, unreliable sealing of the walking system, unreasonable matching of the whole machine, single function, etc.
