Abstract

A hydraulic system of a novel multifunctional orchard work vehicle comprises an oil tank, a quadruple gear pump, electromagnetic reversing valves, proportional flow valves, electromagnetic overflow valves, an adjusting one-way throttle valve, hydraulic oil cylinders and hydraulic motors. According to the hydraulic system of the novel multifunctional orchard work vehicle, on the basis of achieving traveling of a vehicle and lifting of an operating platform, overflow loss and throttle loss u are counteracted while throttle speed regulation is adopted, and work requirements can be well met; an electric-drive fan and a return oil filter are additionally arranged at an oil return opening, and the cooling effect is enhanced; and the hydraulic system is simple in overall structure, high in flow, sufficient in rotating and correcting power, good in cooling effect and convenient to use.

Description

technical field [0001] The invention relates to a novel multifunctional orchard operation vehicle, in particular to a hydraulic system of a novel multifunctional orchard operation vehicle. Background technique [0002] Compared with other transmission methods, hydraulic transmission has the advantages of large power-to-volume ratio, stepless speed regulation, easy automation, stability, long life, easy overload protection, and flexible layout. However, in the past, orchard operating vehicles using hydraulic transmission had problems such as high hydraulic oil temperature and insufficient steering power. In order to solve these problems, a new hydraulic system of orchard work vehicle is designed. Contents of the invention [0003] The purpose of the present invention is to propose a hydraulic system of a novel multi-functional orchard operation vehicle. On the basis of realizing vehicle walking and operation platform lifting, the hydraulic system solves the problems of hig...
