Abstract

A uni-body type engine-driven plough comprises a plough frame, a front handrail, a back handrail, an engine, a transmission case, a clutch, a ploughshare, a driving wheel, a walking wheel, a back float wheel and a transmission device. The engine and the transmission case are respectively arranged at the front part and the back part of the plough frame. The driving wheel is arranged at the lower part of the plough frame. By taking advantage of the speed change of a belt wheel and a chain wheel of the transmission device, the driving wheel is finally caused to plough by a driving gear. The walking wheel is rotatably connected with the front handrail and hinged on the plough frame by the front handrail. The back end of the plough frame is provided with a traction rod. Two ends of the traction rod are respectively connected with the plough frame and a back float wheel bracket. The traction rod is provided with a nut and a screw mandrel which are used for adjusting the lift and drop of the ploughshare. The uni-body type engine-driven plough has the advantages of reasonable design, novel shape, small volume, light weight and small turning radius, can turn around at an area of 0.3-0.5 square meter, does not put down a field or damage seedlings, is conveniently, easily and comfortably operated and reduces the physical energy consumption of an operator.

Description
