Motorised cultivator, with rotating working tines - has series of working tines, rotating about same axis, but with outer tines rotating in opposite direction to inner tines

摘要

The cultivator consists of an engine (2), driving a rotor shaft (11). The working teeth (30, 40, 50 ,60) are mounted on the shaft. The shaft is mounted at the end of a transmission arm (9), which carries a mechanism designed to transmit the forces, produced in the engine, to the shaft. The transmission (8, 9, 10 ,11) is designed to divide the engine power, to produce a contra rotating driving forces on the two parts of the shaft (11 ,22). The outer working tines (30 ,40) are carried on the main drive shaft (11) and rotate in the normal sense. The inner working tines (50 ,60) are carried on the secondary shaft and rotate in the opposite sense. USE/ADVANTAGE - It produces a simple and compact cultivator, which produces little in the way of forces and movement, which might be harmful to the operator.
