A battery jar is connected with a DC motor by an overload protection circuit, an output shaft of the motor is provided with a motor shaft belt wheel, a rolling knife shaft belt wheel is arranged on a circular column helical rolling knife shaft, the motor shaft belt wheel is in transmission connection with the rolling knife shaft belt wheel by a transmission belt, a straight knife is also arranged in an outer shell and a circular column helical rolling knife is rotated around the circular column helical rolling knife shaft to form a sheared port. The chargeable electric lawn mower of the utility model has the advantages of simple structure of a complete machine, low noise, and no air exhaust pollution; furthermore, the utility model adopts the battery jar and the DC motor as the power source; meanwhile, the damage to grass is small because the wound of the sheared grass is small.
Description
Affiliated technical field
The utility model relates to small-sized garden instrument, especially can be laborsaving, the charged electric mower that cuts the grass on a lawn efficiently.
Background technology
At present, well-known mower structure is in the majority with the gasoline mower.This type of mower is to be power with the gasoline engine, and the blade that drives " impeller " shape pastes the ground high speed rotating, thereby grass is interrupted.Yet, owing to being power with the gasoline engine, exhaust emission and bigger noise appear easily on the one hand; On the other hand, by high speed rotating " impeller " shape blade grass is interrupted and can cause grass to form bigger wound at incision position, untimely maintenance is handled, and can cause lawn large tracts of land damage.
Summary of the invention
For the big and careless big deficiency of fracture damage of the exhaust emission, the noise that overcome existing gasoline engine mower, the utility model provides a kind of rechargeable mower, and this mower does not only have exhaust emission, and noise is little, and the little not easy damaged of the fracture grass blade of grass.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of charged electric mower, have housing, and actuating unit, transmission mechanism and cutting mechanism are set in housing, actuating unit comprises storage battery, direct current generator and overload protecting circuit; Transmission mechanism comprises motor shaft belt wheel, cutter shaft belt wheel and driving-belt; Cutting mechanism comprises cylindrical screw hobboing cutter and straight knife; Storage battery is connected with direct current generator by overload protecting circuit; the output shaft of motor is provided with the motor shaft belt wheel; the cylindrical screw cutter shaft is provided with the cutter shaft belt wheel; motor shaft belt wheel and cutter shaft belt wheel are in transmission connection by driving-belt; also be provided with straight knife in the enclosure, the cylindrical screw hobboing cutter forms sheared edge around the rotation of cylindrical screw cutter shaft.
Skid in order to prevent to produce when adopting belt transmission, further: described motor shaft belt wheel, cutter shaft belt wheel and driving-belt adopt motor shaft synchronous pulley, cutter shaft synchronous pulley respectively and are with synchronously.
In order to reduce the frictional resistance between rotating shaft and shell, further: described cylindrical screw cutter shaft is connected with shell by deep groove ball bearing.
The beneficial effects of the utility model are:
1, storage battery adds direct current generator as power source, little, the no air exhaust emission of noise;
The wound of the grass of 2, cutting off is little, and is little to the grass blade damage;
3, complete machine structure is simple.
