Description

Self-powered mower

Technical field

The utility model relates to a kind of self-powered mower, belongs to the machinery of mowing.

Background technology

Present disclosed mower mainly contains two big classes, one class is based on from translator, and the twolip cutter by power drive monolithic stretched is to the pruning of vegetation, but the mower of this class is because power is little, cutting efficiency is low, can only be used for the pruning operation of small-sized garden lawn.Another kind of is to be power with the tractor, the mower base is provided with hanger bracket, the bottom of base is provided with road wheel, be mainly used in farm work, because of based on tractor dynamic power, this outputting power is by behind the transmission case assembly, transport to main shaft through transmission device again, drive the blade rotation by main axis rotation vegetation is pruned, have compact conformation, the characteristics that mowing efficient is high.But its power of mower that is used for farm work is from tractor, therefore mower must both have power output, the plant equipment that has power-driven walking mechanism is again drawn, usually as having the tractor-drawn of power output, and can not be used for the plant equipment of unpowered output, so use occasion is restricted.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, applicable to the self-powered mower of unpowered output plant equipment.

The utility model is that the technical scheme that achieves the above object is a kind of self-powered mower, comprise gasoline engine, clutch, driving-belt, by cutter shaft be installed in cutter shaft assembly and the frame that the blade on the cutter shaft constitutes, it is characterized in that: the top of described frame is connected with gasoline engine, the bottom of frame is connected with cylinder, front portion in frame is equipped with draw bar, the output shaft of gasoline engine is connected with cutter shaft by clutch and driving-belt, and the two ends of cutter shaft are connected the both sides of frame respectively by bearing, bearing block; Both sides have the both sides that the crank shaft support is hinged on frame, and the spindle nose in the crank axle outside is equipped with wheel, also are hinged with on the frame and regulate the mowing height adjustment mechanism, and the bottom of governor motion is connected with support.

The utility model is a power with the gasoline engine that carries, transport to cutter shaft by clutch and driving-belt, owing to be equipped with many on the main shaft blade, can drive the blade rotation by cutter shaft prunes vegetation, compact conformation, therefore can not have the plant equipment traction of power output by any one, as drawing with dynamic output or the tractor or the automobile that do not have power to export, use occasion is unrestricted.The utility model is owing to be that gasoline engine provides power, and by the plant equipment traction that can walk, the mowing fabric width is long, can keep higher mowing efficient.When the utility model is walked at mower,, can reduce the factor affecting such as height of ground type, vegetation effectively, improve the pruning quality of vegetation, and can regulate the height of mowing by governor motion by cylinder and wheel support mower, easy to use.
