Plant protection machine with variable wheelbase and wheelbase with high ground clearance and its wheel drive system

Abstract

The invention discloses a high ground clearance and variable wheel distance and axle distance type plant protection machine. The high ground clearance and variable wheel distance and axle distance type plant protection machine comprises an upper vehicle frame and a lower vehicle frame, wherein the upper vehicle frame and the lower vehicle frame are connected by a miniature rotary platform; a power system, a main variable-speed system, a hydraulic system, a driving operation system, a pesticide spraying and pollinating system, a fertilizer applying system, and the like are symmetrically arranged around a central rotary platform according to a gravity center balance ratio principle; the lower vehicle frame is mainly provided with four foldable and telescopic support legs, and the walking, steering, change of wheel distance and axle distance, adjusting of ground clearance and gravity center height, and other functions of the machine are realized by a corresponding wheel rim transmission system. The invention also discloses the wheel rim transmission system; by utilizing the mixed transmission type of universal transmission, chain wheel transmission and bevel gear transmission, the wheel distance and axle distance can be adjusted. The high ground clearance and variable wheel distance and axle distance type plant protection machine has the advantages that the structure is compact, the function is complete, the working is stable, the application range is wide, the cruising ability is strong, the operation is easy, and the operation efficiency is high. The wheel rim transmission system has the advantages that the stability and operability are good, the driving force is large, the effect of one machine with multiple functions is realized, and the requirement of whole machine is met.

Description

technical field [0001] The invention relates to agricultural machinery, especially a plant protection machine. Background technique [0002] The target of plant protection machinery is crops. Diseases, insects and weeds are complex and changeable, which restricts the professional development of plant protection machinery. There are many types of pests and diseases and the uncertainty of occurrence determines the diversity of plant protection measures. Pests and diseases and insect pests vary from sporadic, sudden, large and small, which are different from the simple and consistent cultivation and harvest of crops. It is difficult to control diseases and insect pests in a regular and unified manner, and it is also difficult for farmers who lack certain plant protection technology and knowledge to undertake it independently. In recent years, although some specialized plant protection control teams with different organizational forms have been established in various places, t...

Problems solved by technology

Under this kind of management system, it is difficult to develop large-scale and intensive production, it is difficult to fundamentally change extensive production, and there is no market for large-scale plant protection machinery.

Due to the characteristics of plant protection work, without the strong support of the central government, it will be difficult for the unified control of plant protection to develop smoothly, and it will also affect the application of large-scale plant protection machinery.
