Mechanical transmission type four-wheeled steering and two-wheeled driving wheel-span-variable high-ground-clearance insecticide sprayer

Abstract

The invention relates to a mechanical transmission type four-wheeled steering and two-wheeled driving wheel-span-variable high-ground-clearance insecticide sprayer. With the adoption of the invention, the high-ground-clearance insecticide sprayer realizes the functions of capability of vertically hoisting a cab, mechanical transmission, four-wheeled steering and adjustable wheel span. The mechanical transmission type four-wheeled steering and two-wheeled driving wheel-span-variable high-ground-clearance insecticide sprayer mainly comprises a steering machine, a right-angle box, a front transverse beam, an insecticide spraying frame hoisting frame, a steering oil cylinder, a rear transverse beam, a driving axle, an oil tank, an insecticide spraying frame, a guardrail, a speed changing box, an engine, an insecticide pump, a girder, a cab vertical hoisting system, a cab, a driving vertical shaft, a special planetary wheel hub reduction gear for a high-ground-clearance machine, a driving wheel, an insecticide tank, an insecticide tank frame, a steering vertical shaft, a guide wheel and a steering arm.

Description

technical field [0001] The invention relates to a mechanical transmission type four-wheel steering two-wheel drive variable wheelbase high ground clearance spraying machine. Background technique [0002] At present, the cabs of the existing high-ground-clearance spraying machines are mostly fixed above the frame without vertical lifting adjustment function, and the working mode is mostly hydraulic drive and two-wheel steering. Its disadvantages are: the overall center of gravity of the spraying machine It is too high, which is not conducive to driving on the road. The cab cannot be adjusted up and down, and the staff's field of vision cannot be adjusted to the best level with the height of the crops, which will eventually affect the spray quality; because the hydraulic drive uses oil pipes to transmit pressure oil, the pressure loss is relatively large, and the engine power is limited. The effective utilization rate will be reduced. Once the oil is mixed with air, it is easy...

Problems solved by technology

[0002] At present, the cabs of the existing high-ground-clearance spraying machines are mostly fixed above the frame without the vertical lifting adjustment function, and the working methods are mostly hydraulically driven and two-wheel steering. Its disadvantages are: the overall center of gravity of the spraying machine It is too high, which is not conducive to driving on the road. The cab cannot be adjusted up and down, and the staff's field of vision cannot be adjusted to the best level with the height of the crops, which will eventually affect the spray quality. Because the hydraulic drive uses oil pipes to transmit pressure oil, the pressure loss is relatively large, and the engine power is limited. The effective utilization rate will be reduced. Once the oil is mixed with air, it is easy to cause the sprayer to crawl, vibrate and make noise, which will affect the working performance of the system. The oil is easily polluted, which will affect the system's work. Reliability, high manufacturing precision of hydraulic components, strict use and maintenance, failures are not easy to check and eliminate; two-wheel steering turning radius is too large, maneuverability is not high, and machine operation efficiency is greatly affected
