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.
