Abstract

The utility model relates to a small garden tool, particularly a chargeable electric lawn mower which is used for pruning lawns and has the functions of labor saving and high efficiency. 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

The charged electric mower
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.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an external structure schematic diagram of the present utility model.
Fig. 2 is an interior schematic diagram of the present utility model.
Fig. 3 is the utility model overload protecting circuit figure.
Among the figure: 1. housing, 2. direct current generator, 3. motor shaft belt wheel, 4. conveyer belt; 5. cylinder cutter shaft belt wheel, 6. deep groove ball bearing, 7. cylindrical screw hobboing cutter, 8. straight knife 9. cylindrical screw cutter shaft a. storage batterys; b. charging socket, c. normally open contact, d. light emitting diode 1, e. resistance R 1; f. normally closed interlock, g. light emitting diode 2, h. triode; i. adjustable resistance R3, j. resistance R 2, k. relay; m. grip switches, n. protection switch, p. electrothermal relay.
Embodiment
As shown in Figure 1 and Figure 2, a kind of charged electric mower has housing 1, and actuating unit, transmission mechanism and cutting mechanism are set in housing 1, and actuating unit comprises direct current generator 2 and overload protecting circuit, and direct current generator 2 is connected with overload protecting circuit.Overload circuit as shown in Figure 3; storage battery a, direct current generator 2 are contained in the metal shell 1, and charging plug b, normally open contact c, light emitting diode 1d, resistance R 1e, normally closed interlock f, light emitting diode 2g, adjustable resistance R3i, resistance R 2j, triode h, relay k, protection switch n, electrothermal relay p are contained in the same plastic housing.Cutting mechanism comprises cylindrical screw hobboing cutter 7 and straight knife 8, and cylindrical screw hobboing cutter 7 is provided with cylindrical screw cutter shaft 10, and cylindrical screw cutter shaft 9 flexibly connects with shell 1, and straight knife 8 is fixedlyed connected with shell 1, forms sheared edge at cylindrical screw hobboing cutter 7 and straight knife 8; Transmission mechanism comprises motor shaft belt wheel 3, cutter shaft belt wheel 5 and driving-belt 4, the output shaft of direct current generator 2 is provided with motor shaft belt wheel 3, cylindrical screw cutter shaft 9 is provided with cutter shaft belt wheel 5, and motor shaft belt wheel 3 is in transmission connection by driving-belt 4 with cutter shaft belt wheel 5.In order to reduce the frictional resistance between rotating shaft and shell, cylindrical screw cutter shaft 9 is connected with shell 1 by deep groove ball bearing 6.
When mounted, earlier motor shaft belt wheel 3 is contained on the direct current generator 2, direct current generator 2 is screwed on metal shell 1 and with overload circuit and is connected, power supply in the overload circuit adopts two joint 12v storage batterys, cylindrical screw hobboing cutter 7 is fixed on the metal shell 1 by deep groove ball bearing 6, requires motor output shaft and cylindrical screw cutter shaft 9 to be parallel to each other and all perpendicular to the side plate of metal shell 1.Cylinder cutter shaft belt wheel 5 is contained on the cylindrical screw hobboing cutter 7, load onto driving-belt 4 at last, require not sideslip of driving-belt 4 energy smooth rotation, in order to prevent that driving-belt 4 from skidding in transmission process, motor shaft belt wheel 3, cutter shaft belt wheel 5 and driving-belt 4 adopt motor shaft synchronous pulley, cutter shaft synchronous pulley respectively and are with synchronously.Straight knife 8 is fixed on the metal shell 1, can rotate around the single-revolution axle, the blade of straight knife 8 is contacted with bus position total length with cylindrical screw hobboing cutter 7, and then return a bit, makes and stays 0.1 mm clearance to form sheared edge between straight knife 8 and the cylindrical screw hobboing cutter 7.
