Fig. 3 is a sectional view of a lawn mower according to the present invention. Fig. FIG. 4 is a cross-sectional view showing a main structure of a cutting mechanism having a double blade of a lawn mower according to one embodiment of the present invention. FIG.

The present invention relates to a cutting mechanism for driving a rotary shaft 1 using the power of a motor M and includes a drive means 10, cutting cutters 20a, 20b, and a cover 30 as main components do.

The driving means 10 according to the present invention is provided to receive a driving force from the rotary shaft 1 of the motor M and has gear trains 15 to transfer the driving force to both sides. The lawn mower includes driving means 10 that rotates through a rotary shaft 1 interlocked with a motor M formed at the rear end portion. The driving means 10 includes a gear train 15, So that the driving force is transferred to both sides.

The gear train 15 of the drive means 10 includes a first gear 11 that receives rotational force from the rotational shaft 1 and a second gear 11 that receives rotational force from the first gear 11, 2 gears 12a and 12b. The driving means 10 includes a first gear 11 integrally formed at the end of one rotary shaft 1 interlocked with the motor M and rotating together with the first gear 11, And the second gears 12a and 12b which rotate on both sides of the rotary shaft 12a to transfer the rotational force to the upper and lower portions of the cutting mechanism. Although it has been shown that the driving means 10 is formed by a pair of second gears 12a and 12b on the upper and lower sides, another gear is formed in the opposite direction to the shaft formed on the second gear 12a The number of gear trains 15 can be increased. However, it is preferable that the number of gear trains 15 is limited to the second gears 12a and 12b because mechanical complexity and mechanical error due to backlash can occur.

The cutting cutters 20a and 20b according to the present invention are respectively connected to the gear train 15 of the drive means 10 and are installed to rotate by a driving force. The cutting cutters 20a and 20b are provided on the second gears 12a and 12b that are integrally formed at the ends of the rotating shaft 1 and rotate on both sides of the first gear 11 rotating together And cutting cutters 20a and 20b rotating in conjunction with each other. The cutting cutters 20a and 20b are integrally fixed to the respective shafts 13a and 13b formed in the second gears 12a and 12b so that the cutters 20a and 20b are rotated by the rotation of the second gears 12a and 12b, (20a) and (20b) rotate together. Although the cutting cutters 20a and 20b are formed of a metal material, a band-shaped cutter formed of a synthetic resin material such as plastic may be connected to the shafts 13a and 13b so as to rotate together.

The cover 30 according to the present invention is provided in the vicinity of the lower portion of the cutting cutter 20a and is provided with a curved portion 31 so as to maintain the cutting cutters 20a and 20b at a certain angle from the ground L Respectively. The cover 30 is coupled to the outside of the lower surface of the cutting mechanism of the present invention. When the user presses the grass, the cutting cutters 20a and 20b must maintain an angle parallel to the ground L, A curved surface portion 31 is provided so that the angle of the cutting mechanism can be maintained. That is, the curved surface portion 31 allows the user to cut the cutting cutters 20a and 20b while keeping the cutting cutters 20a and 20b horizontal with respect to the ground L, Can be removed.

At this time, the cutting cutters 20a and 20b are different from each other in the length of the blades so as to improve the cutting force and facilitate the mowing work. When any one of the cutting cutters 20a and 20b is formed to be short or long, if the cutting cutter 20a provided at the bottom is formed to be long, the grass may be cut and the stones may protrude It is possible to increase the convenience by constructing the cutter 20b so as to defend it or by lengthening the length of the cutting cutter 20b provided on the upper part to sequentially cut the long length of the grass. If the length of the cutting cutter 20b is long, it is possible to solve the problem that the cutter 20b can not be cut easily since it is formed by a long grass and can be blown by the wind and can be lightly shaken so that the worker's working time is shortened, . The cutter 20a formed at the lower portion is formed to be bent upward and the cutter 20b formed at the upper portion is formed horizontally so that the weights of the weeds 20a and 20b, The grass is prevented from being wrapped around the cutting cutters 20a and 20b along the cutter 20a. This configuration reduces the defects of lawn mowers and reduces the work time of workers.

1 to 4, in the use of the present invention, there is firstly a first gear 11 connected to a rotating shaft 1 by using the power of a motor M, and the first gear 11 The cutters 20a and 20b are rotated by the rotation of the second gears 12a and 12b which transfer the driving force to the both sides through the first and second gears 12a and 12b, The angle of the cutting mechanism can be adjusted around the bent portion 31 so that cutting of the paste becomes easier. At this time, the cutting cutters 20a and 20b may be provided with different blade lengths to improve the cutting force and facilitate the mowing work.

As described above, the present invention provides an effect of preventing the safety of the worker by cutting the pebbles which are splashed by the cutting force while improving the cutting power by sequentially cutting grass such as grass, grass and weeds.
