Background technology
At present, well-known mower structure is in the majority with " impeller cutter " gasoline mower and manpower hand-push type mower.This type of gasoline mower is directly to drive the blade subsides ground high speed rotating of " impeller " shape with gasoline engine, thereby grass is interrupted.Yet rotation " impeller " shape blade interrupts grass and can cause grass to form bigger wound and connect the phenomenon that grass roots pulls up at incision position, and untimely maintenance is handled, and can cause lawn large tracts of land damage.And the manpower hand-push type mower is not suitable for the big lawn of area, wastes time and energy.
Summary of the invention
For the fracture damage that overcomes the grass that existing gasoline type mower cut with connect the deficiency that phenomenon that grass roots pulls up and manpower hand-push type mower are wasted time and energy, the utility model provides a kind of gasoline type cylindrical screw hobboing cutter mower, the fracture that this mower is mowed little not easy damaged grass blade and more laborsaving than manpower hand-push type mower, continuous working period is long.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of gasoline type cylindrical screw hobboing cutter mower, has housing, be provided with actuating unit, transmission mechanism and cutting mechanism in housing, actuating unit comprises gasoline engine assembly and clutch pack; Cutting mechanism comprises cylindrical screw hobboing cutter and straight knife, and the cylindrical screw hobboing cutter is provided with the cylindrical screw cutter shaft, and cylindrical screw cutter shaft and housing flexibly connect, and straight knife is fixedlyed connected with housing, forms sheared edge between cylindrical screw hobboing cutter and straight knife; Transmission mechanism comprises gasoline engine output pulley, cutter shaft belt wheel and driving-belt, the gasoline engine output pulley is arranged on the output shaft of clutch pack, the cutter shaft belt wheel is arranged on the cylindrical screw cutter shaft, and gasoline engine output pulley and cutter shaft belt wheel are in transmission connection by driving-belt.
In order to prevent that mower driving-belt appearance in use for some time is lax and to influence the transmission effect, further: described transmission mechanism also comprises the distend wheel assembly, the distend wheel assembly comprises distend wheel and distend wheel support, regulating wheel and distend wheel support flexibly connect, the distend wheel support is connected with housing, and the distend wheel periphery compresses driving-belt.
Skid in order to prevent to produce when adopting belt transmission, more further: described gasoline engine output pulley, cutter shaft belt wheel and driving-belt adopt gasoline engine output synchronous pulley, cutter shaft synchronous pulley respectively and are with synchronously.
In order to reduce the frictional resistance between rotating shaft and housing, further: the junction of described cylindrical screw cutter shaft and housing is provided with ball bearing.
The beneficial effects of the utility model are:
1. the wound of the grass of cutting off is little, and is little to the grass blade damage;
2. laborsaving, efficient;
3. complete machine structure exquisiteness.
