Abstract
The utility model relates to a lawn moving disk improvement structure of an electric lawn mower. The structure comprises a rotating disk and a cutter rope, wherein the rotating disk is provided with a tabular body, a connecting part for being connected with a driving device is arranged on the surface of the body, and a groove is formed in the surface of one side, on which the connecting part is arranged, of the body; the cutter rope is arranged in the groove in a penetrating mode, so that the cutter rope penetrates through the side surface of the body; a counterweight element is fixed on the side surface, opposite to the cutter rope, of the body, so that when the lawn moving disk is used, the generated resistance is reduced; then, the volume of a battery can be reduced, and the service time of the battery can be prolonged.
Description
Technical field
A mowing dish structure-improved for power-operated mower, is espespecially used in the mowing dish of back-pack electric mower.
Background technology
The existing engine for mower is take petrol and diesel oil as driving power resources, can produce much waste gas, cannot meet the demand of environmental protection, therefore inventor of the present utility model develops one " direct-driving electric motor mower " then, solve the disappearance of aforementioned existing mower, the China Patent No. of being somebody's turn to do " direct-driving electric motor mower " is 201220344364.8.But, inventor of the present utility model finds in the process of constantly research and development, because the rope body of cutter is for being oppositely arranged, therefore the body resistance in the time that rotation is mowed of restricting can become greatly, restricts body in the rotary speed that can mow if will keep, and must expend larger electric power, battery can be exhausted fast, if increase the capacity of battery, can make again this kind of shoulder carrying mower weight increase, and be unfavorable for that user uses.
Utility model content
Main purpose of the present utility model is, reduces mowing and coil the resistance producing in the time using, and then dwindle battery volume and extend the service time of battery.
For reaching above-mentioned purpose, the utility model provides a kind of mowing dish structure-improved of power-operated mower, includes a rotating disk and a cutter rope, wherein:
This rotating disk has the body of flat, body surface is provided with the connecting portion in order to connecting drive device, body is concaved with groove in connecting portion one side surface, and be provided with perforation in the sidewall surfaces of groove one side, perforation runs through the side surface of body, and body is provided with locating hole on the relative side surface of perforation, and locating hole is fixed with weight element;
This cutter rope has rope body and stop part, and stop part is connected and fixed on rope body one end, and the external diameter of stop part is greater than the punch inside diameter of rotating disk, and rope body is arranged in the perforation of body, and is passed by the side surface of body, makes stop part be held in the sidewall surfaces of groove.
The mowing dish structure-improved of described power-operated mower, wherein: the groove of this rotating disk is provided with guide ramp with respect to the opposite side of perforation.
The mowing dish structure-improved of described power-operated mower, wherein: in the locating hole of this rotating disk, be provided with internal thread, and the outer surface of weight element is provided with external screw thread, external screw thread is threadedly connected to internal thread.
The beneficial effects of the utility model are: utilize cutter rope to be arranged at rotating disk one side, rotating disk opposite side, with weight element balance rotating disk, coils to reduce mowing the resistance being produced in the time using, and then can dwindle battery volume and extend the service time of battery.

Description of reference numerals: 1-rotating disk; 11-body; 12-connecting portion; 13-groove; 14-perforation; 15-locating hole; 151-internal thread; 16-guide ramp; 2-cutter rope; The 21-body of restricting; 22-stop part; 3-weight element; 31-external screw thread; 4-drive unit.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, by knowing and find out in figure, the utility model includes a rotating disk 1 and a cutter rope 2, wherein:
This rotating disk 1 has the body 11 of flat, body 11 surfaces are provided with the connecting portion 12 in order to connecting drive device 4, body 11 is concaved with groove 13 in connecting portion 12 1 side surfaces, and be provided with perforation 14 in the sidewall surfaces of groove 13 1 sides, groove 13 is provided with guide ramp 16 with respect to the opposite side of perforation 14, the side surface that perforation 14 runs through body 11, and body 11 is provided with locating hole 15 on the relative side surface of perforation 14, and locating hole 15 is fixed with weight element 3.Moreover, in this locating hole 15, be provided with internal thread 151, and the outer surface of weight element 3 being provided with external screw thread 31, external screw thread 31 is threadedly connected to internal thread 151.
This cutter rope 2 has rope body 21 and stop part 22, stop part 22 is connected and fixed on rope body 21 one end, the external diameter of stop part 22 is greater than perforation 14 internal diameters of rotating disk 1, and rope body 21 is away from the other end of stop part 22, in the groove 13 of rotating disk 1, to penetrate perforation 14, and passed by the side surface of body 11, make stop part 22 be held in the sidewall surfaces of groove 13.
Refer to Fig. 1, shown in Fig. 2 and Fig. 4, by knowing and find out in figure, when the utility model is in the time using, it is the drive unit 4 that the connecting portion of rotating disk 1 12 is connected in to mower, in the time that drive unit 4 drives rotating disk 1 fast rotational, the part that rope body 21 exposes body 11 can produce cutting power, allow user can carry out cutting operation, and owing to being only provided with a cutter rope 2 on the utility model rotating disk 1, rotate with weight element 3 balance rotating disks 1 again, therefore in the time that user mows, only have a cutter rope 2 can produce resistance, and then allow drive unit 4 can keep comparatively easily the rotating speed of rotating disk 1, reduce expending of electric power, extend the service time of battery, and can reduce the capacity of battery, allow user can bear easily mower.Moreover while mowing due to mowing dish, the rotating speed that only needs drive unit 4 to provide less torsion to keep rotating disk 1, therefore, if do not dwindle the battery volume of mower, also can dwindle the volume of drive unit 4, allows user can bear easily mower.
