The design includes the choice of motor, the choice of transmission, the design of some parts and the design of the cultivator knife-axis etc. The plowing outgoing power is from engineering to the gearbox using belts , after that be transferred to the arbor of rotate knife. Between gearbox and the arbor of rotate knife adopt chains to transmit; The design of arbor of rotate knife adopt three parts, the middle part is hollow rolled steel , two side parts is solid rolled steel, may process Shoulder-axis to lay on roller bearing and Cover. The surface is neat after till, the cultivator designed in the paper can e the problems of small-power , complex structure, trouble operation, low plowing depth etc. It can meet the request of greenhouse.
