Application (patent)No. Cn01241718.1application date 200 1.05.22 Applicant (patent) Wang Huicheng, inventor (designer) of Shenyang Agricultural University; Ding; Liu Wei; Wei Fenglan; Li xingde? abstract
An electric rotary cultivator comprises a motor, a reduction gear box, a transmission shaft, a frame, a resistance shovel and the like, and is characterized in that the reduction gear box is fixedly connected to the frame, and a meshing bevel gear pair is arranged in the reduction gear box, a small bevel gear is coaxially connected with the motor, and a large bevel gear is coaxially connected with the transmission shaft; A wheel frame with walking wheels is rotatably connected to the frame; The frame is equipped with an elastic positioning pin shaft which can stop the wheel frame, and the inner end of the elastic positioning pin shaft is in contact with the top plate with a rotating handle. The advantages are: after replacing diesel engine or gasoline engine with motor, the structure is simplified, the weight is reduced, the operation is convenient, there is no noise, no harmful gas emission, and the coaxial conduction reduces the loss.
