Mechanical transmission type four-wheel-steering four-wheel-driven variable-tread high-ground-clearance insecticide sprayer

Abstract

The invention provides a mechanical transmission type four-wheel-steering four-wheel-driven variable-tread high-ground-clearance insecticide sprayer which is mainly formed by an engine, a gearbox, a transfer case, a driving axle, a right angle box, a steering vertical shaft, a special mechanical high-ground-clearance planetary hub reductor, a liquid pump, a liquid tank, a tank rack and a spraying frame. The high-ground-clearance insecticide sprayer achieves mechanical transmission. The mechanical transmission type four-wheel-steering four-wheel-driven variable-tread high-ground-clearance insecticide sprayer has the most obvious advantages that mechanical transmission is stable and reliable, a power utilization rate of the engine is high, the mechanical transmission type four-wheel-steering four-wheel-driven variable-tread high-ground-clearance insecticide sprayer is convenient to maintain, has high passing performance in severe environments, adopts a four-wheel-steering and four-wheel-driven structure so as to have a strong driving force, has a small turning radius and is flexible to steer, and further a variable tread is adaptable to requirements of different ridge distances, and thus, the insecticide sprayer has very high operation efficiency.

Description

technical field [0001] The invention relates to a mechanical transmission type four-wheel steering four-wheel drive variable wheelbase high ground clearance spraying machine. Background technique [0002] At present, most of the existing high ground clearance spraying machines adopt hydraulic transmission and two-wheel steering. Its disadvantages are that the driving force is weak, the use and maintenance of hydraulic components are relatively strict, and the viscosity of the oil changes with the change of temperature, which is not suitable. Work in environments with high or low temperatures. Since the hydraulic transmission uses oil pipes to transmit pressure oil, the pressure loss is relatively large, resulting in a decrease in the effective utilization of engine power. Once air is mixed in the oil circuit, the working performance of the hydraulic transmission system will also be reduced, and it is easy to cause spraying. Machine crawling, vibration and noise and other ph...

Problems solved by technology

[0002] At present, most of the existing high ground clearance spraying machines adopt hydraulic transmission and two-wheel steering. Its disadvantages are that the driving force is weak, the use and maintenance of hydraulic components are relatively strict, and the viscosity of the oil changes with the change of temperature, which is not suitable. Work in environments with high or low temperatures

Since the hydraulic transmission uses oil pipes to transmit pressure oil, the pressure loss is relatively large, resulting in a decrease in the effective utilization of engine power. Once air is mixed in the oil circuit, the working performance of the hydraulic transmission system will also be reduced, and it is easy to cause spraying. machine crawling, vibration and noise, etc., causing the overall performance of the sprayer to be affected

The oil is also prone to pollution and contamination. Once the oil is contaminated, it will affect the reliability of the entire hydraulic system. It is not easy to check and eliminate when a fault occurs

[0003] Most of the existing high-ground-clearance sprayers adopt the design method of hydraulic transmission and two-wheel steering, which has the disadvantages of weak driving force and large turning radius. , the passing capacity of the sprayer will be reduced

Because the turning radius of the above-mentioned spraying machine is too large, the maneuverability of the spraying machine will be reduced, and the operating efficiency of the machine will be greatly affected.
