Abstract

A paddy-upland crawler tractor is an integration of a power transmission device, a steering operating mechanism, a traveling mechanism, a working device, a hydraulic system, an electrical system and other systems. A transmission system includes a mechanical shift gearbox and a rear axle, positioned high at the tail end of a planet gear; a steering system is composed of a circulating ball steeringgear, matching with an adjustable-pressure steering operating valve and a steering wheel operating mechanism. A frame is an integrally welded frame having frame functions and service frame functions.A traveling system is in triangular arrangement, driving wheels are positioned high; a rocking trolley and oblique single-rod tension guide wheels are provided, matching with a quick-changing dozer blade and a forced entry lifting mechanism, thereby providing expanded operation functions, and allowing the tractor to self-recue from being trapped. The paddy-upland crawler tractor helps solve the problem that a tractor sinks when cultivating in a paddy field; protected cultivation of a paddy field is achieved; the paddy-upland crawler tractor is also suitable for plowing traction, dozing and other operations, is high in overall utilization rate and meets demand for application of paddy machinery in paddy-upland rotation.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a crawler tractor used both for paddy fields and dry fields, in particular to a crawler tractor capable of bulldozing at the front end, rotary tillage, ridging, plowing, and chemical spraying at the rear end, and traction operations multifunctional crawler tractor. Background technique [0002] At present, the degree of sowing and harvesting mechanization of paddy field operations in my country has been greatly improved. The bottleneck of paddy field operations is farming. For a long time, walking tractors, wheeled tractors or animal-powered implements have been basically used for operations. Farming with walking tractors or animal-powered machinery has low work efficiency and high labor intensity; continuous use of large and medium-sized wheeled tractors for farming will further deepen the mud foot of the paddy field, which will bring difficulties to the next operation of the...
