Large-ground-clearance self-propelled plant protection machine with full hydraulic system

Abstract

A large-ground-clearance self-propelled plant protection machine with a full hydraulic system comprises a cab, a pesticide tank, a prime motor system, the hydraulic system, a spraying frame assembly and a chassis structure system, wherein the cab is fixedly arranged at one end of a chassis, the pesticide tank is fixedly arranged in the middle of the chassis, and the spraying frame assembly is arranged at the other end of the chassis. A width-variable drive hydraulic cylinder is arranged on a wheel frame, walking hydraulic motors are arranged on wheels, height-variable drive hydraulic cylinders are vertically arranged at four corners of the wheel frame, hydraulic cycloid motors and slewing bearings are arranged at the lower ends of the height-variable drive hydraulic cylinders, and energy accumulator valve groups are arranged at the upper portions. The large-ground-clearance self-propelled plant protection machine has the advantages of being reasonable in structure, good in steering performance, adjustable in ground clearance and good in stability performance and making spray rods and spray frames convenient to lift and fold, can adapt to low-stem crops and can also adapt to high-stem crops. In addition, a machine body can be automatically kept horizontal, the stability and comfort are higher, meanwhile the machine can smoothly turn in narrow places and is higher in flexibility.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a pesticide spraying device. Background technique [0002] As an important part of agricultural production, self-propelled plant protection machines have attracted more and more attention in my country. Although my country has carried out some research and development on high-clearance sprayers, the main models are still difficult to meet the needs of high-stalk crops. In complex terrain operations and other requirements, only low-stem crops can be sprayed alone. The core component of the high ground clearance sprayer, the self-propelled chassis frame, only roughly imitates foreign models, and the self-propelled chassis frame of the sprayer is cumbersome, vibration and noise are huge, low efficiency and poor stability, etc. question. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a full hydraulic system high ground clearance self-prop...
