Abstract
The utility model relates to an electric weeder, which comprises a casing of a built-in motor, a bend pipe and a shearing device which is provided with a thread packet, wherein an output shaft of the motor is connected with one end of a flexible shaft which is arranged in the bend pipe and the other end of the flexible shaft is linked with the thread packet. The utility model is characterized in that a synchronous belt drive device for speed reduction is arranged between the other end of the flexible shaft and the thread packet. The synchronous belt drive device is composed of a synchronous belt which is arranged in a box body, a big belt wheel and a small belt wheel, wherein the box body is fixed to a bottom board of the shearing device; a small shaft of the small belt wheel is connected with the flexible shaft; a big shaft of the big belt wheel is connected with the thread packet. The utility model has the advantage that the thread packet and the motor can respectively rotate at different rotation speeds by the synchronous belt drive device by selecting definite speed reducing ratio as required after the structure is adopted. Thereby, the torque of the motor can be enhanced under the condition of satisfying the requirements of the rotation speed of the thread packet, so that the use requirements of different occasions can be satisfied.
Description
Technical field
The utility model relates to the electrodynamic type mower on finishing in a kind of flower bed, lawn, the flower garden, cutting meadow.
Background technology
Existing electrodynamic type mower mainly comprises casing, bend pipe and shear, wherein bend pipe one end links to each other with casing, the other end is connected to shear, and motor then is installed in casing, the output shaft of motor by being arranged in bend pipe flexible axle and the line bag of shear link.During use, push the power switch on the casing, make electric motor starting, drive the flexible axle rotation thereupon, drive the line bag then and make the high speed rotating shearing motion, to reach the purpose on finishing, cutting meadow.But in design process, find, owing to consider the safety of operation and the designing requirement of electric tool, it is too fast that the velocity of rotation of line bag can not design, and promptly the rotating speed of line bag is subjected to certain restriction, and the line bag is directly driven by flexible axle by motor, so the difficult with it coupling of rotating speed of motor.Moreover, under same power of motor, also can't improve the torque of motor, so that it can't satisfy the instructions for use under the different occasions.
Summary of the invention
Technical problem to be solved in the utility model is to overcome defective of the prior art, provides a kind of motor and line to wrap in the electrodynamic type mower of work under the different rotating speeds.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this electrodynamic type mower comprises the shear of casing, bend pipe and the band line bag of built-in motor, wherein said motor output shaft links with flexible axle one end that is arranged in bend pipe, the other end of described flexible axle then links with above-mentioned line bag, it is characterized in that: the synchronous belt transmission device that also is provided with deceleration usefulness between the other end of described flexible axle and the line bag.
Described synchronous belt transmission device can be made up of the synchronous band and the large and small belt wheel that are installed in the casing, wherein casing is fixed on the base plate of shear, and the little axle of described small pulley links with described flexible axle, and the macro-axis of described big belt wheel then links with above-mentioned line bag.
Compared with prior art, advantage of the present utility model is: after adopting said structure, can select certain speed reducing ratio as required, by synchronous belt transmission device the line bag is rotated respectively under different rotating speeds with motor, thereby can be under the requirement of satisfying line bag rotating speed, improve the torque of motor, so that satisfy the instructions for use under the different occasions.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this electrodynamic type mower comprises casing 1, bend pipe 2, synchronous belt transmission device 3 and shear 4, and wherein shear 4 comprises line bag 44 that is positioned at line clad 43 and spiral cover 45 and protective cover 41 and the base plate 42 that plays protective action again; Synchronous belt transmission device 3 then by be installed in the casing 31 be with 32 synchronously, big belt wheel 36 and small pulley 34 form, described casing 31 is fixed on the base plate 42 of shear by screw, large and small belt wheel is installed in respectively by on the macro-axis 35 of bearing supporting and the little axle 33, its medium and small axle 33 links with flexible axle 6 one ends that are positioned at bend pipe 2, and flexible axle 6 other ends then connect with motor 5 output shafts that are positioned at casing 1; Described macro-axis 35 then links with above-mentioned line bag 44.
During work, push the power switch that is positioned on the casing 1, make motor 5 high speed rotating, flexible axle 6 high speed rotating thereupon, the small pulley 34 that drives in the synchronous belt transmission device rotates, then by driving big belt wheel 36 rotations with 32 by required speed reducing ratio synchronously, drive line bag 44 by macro-axis 35 again and do the rotational shear campaign.Therefore after adopting said structure, both made the different rotating speed of selection of Motor, and also can make the line bag still by certain rotary speed working, thereby can satisfy the instructions for use under the different occasions by corresponding speed reducing ratio.
