Paddy-upland crawler tractor

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...

AI Technical Summary

Problems solved by technology

[0005] In addition, some domestic enterprises have produced paddy field tillage machines. Most of these paddy field tillage machines have borrowed the production structure of harvesters and were not developed according to the needs of paddy field farming. Therefore, there are the following problems: simple appearance, poor operating comfort, walking system Unreliable sealing, unreasonable matching of the whole machine and single function

However, this type of model has problems such as low traction efficiency, poor steering reliability, and low work efficiency.
