Adjustable height type full hydraulic driving chassis of high-ground-clearance mist spraying machine and hydraulic system thereof

Abstract

The invention relates to an adjustable height type full hydraulic driving chassis of a high-ground-clearance mist spraying machine and a hydraulic system of the adjustable height type full hydraulic driving chassis. The adjustable height type full hydraulic driving chassis comprises a frame, a front supporting leg, a rear supporting leg, a front axle, a spraying rod spraying frame, a chassis lifting system, a travelling hydraulic driving system, a power system and a hydraulic assisting turning system. The adjustable height type full hydraulic driving chassis is characterized in that the frame is arranged at the upper parts of the front supporting leg and the rear supporting leg; the front axle is arranged between the frame and the front supporting leg; the spraying rod spraying frame is hinged to the frame; the chassis lifting system comprises a vertical rod telescoping sleeve, a vertical column, a hydraulic pump, a lifting hydraulic cylinder, a hydraulic control one-way valve and a manual operating valve; the travelling hydraulic driving system comprises a hub hydraulic motor, a variable pump, an oil supplementing pump, an one-way valve, a safety valve, an oil supplementing overflowing valve, a backpressure overflowing valve and a shuttle valve; the power system is fixedly mounted on the frame; the hydraulic assisting turning system comprises a hydraulic pump, a speed regulating valve, a follow-up valve and a turning oil cylinder. The adjustable height type full hydraulic driving chassis is simple in structure, stable in power output, wide in height adjusting range, and high in stability, and meets the demand of plant protection of crops at different growth periods and in planting lands with different height.

Description

technical field [0001] The invention relates to an agricultural plant protection mechanical part, in particular to a height-adjustable full-hydraulic drive chassis of a high-ground-gap sprayer and a hydraulic system thereof. Background technique [0002] With the development of agricultural modernization, agricultural production has developed from extensive and low-tech to refined and high-tech. The high clearance sprayer is a plant protection machine developed to adapt to modern and refined agricultural operations. This machine can be widely used in various aspects of crop field management such as spraying water after planting, spraying herbicides, spraying insecticides and disease-resistant drugs, and spraying foliar fertilizers, etc., and plays an important role. At present, the chassis of high-ground-clearance sprayers basically relies on mechanical transmission. Due to the high ground clearance and the long distance between the engine and the driving wheel, chain trans...

AI Technical Summary

Problems solved by technology

At present, the chassis of the high-ground-clearance sprayer basically relies on mechanical transmission. Due to the high ground clearance and the long distance between the engine and the driving wheel, chain transmission is generally used, which increases the noise during driving, and the chain is prone to failure under a large impact. Secondly, due to the complex mechanical transmission structure, numerous parts, and the limited layout of the chassis, it brings great inconvenience to the assembly and maintenance of the whole machine, the operation of personnel is complicated, the life of the clutch and gearbox is short, and the driving comfort is poor. Moreover, the ground clearance of the chassis is fixed, the scope of application is small, and it cannot meet the plant protection needs of different growth periods of crops
