Abstract

The present invention relates to a blade for a lawn mower, mowing work by projecting the engaging frame 26 larger than the diameter of the cover 24 at the bottom of the case 22 around the connection hole 12 to the main body portion 14 When the jam frame 26 is to block the gap between the cover 24 and the blade 10 of the case 22 to prevent the weeding grass or lumber and various foreign matters caught.

Description

Blade for mowing {GRASS ELIMINATOR BLADE}

The present invention relates to a blade for mowing, and in particular, to prevent the weed grass or various foreign matters from being caught through the gap between the cover and the work.

In general, there are many types of blades for mowing, such as blades extending on both sides of a long strip-shaped metal plate and connecting a plurality of blades with links on the outside of the disc. Is connected to the driven shaft having the drive unit of the lawn mower through the ball is configured to mowing by rotating by the power of the lawn mower.

That is, as shown in FIG. 1, the driving shaft 100 and the bevel gear 102 are engaged with each other, and the driven shaft 108 protruding from the cover 106 at the bottom of the case 104 has a connection hole having a central portion of the blade 110. When penetrating, the blade 110 is clamped between the inner and outer pressing pieces 114 and 116 when the nut 112 is tightened, and is configured to rotate along the driven shaft 108.

Therefore, a gap is generated between the cover 106 fixed to the case 104 and the blade 110 rotating along the driven shaft 108 by simply forming a flat plate. Since the overload is generated between the cover 106 and the blade 110, resulting in shortening of the life of the lawn mower and also reducing the rotational force of the blade 110 so that weeding can not be made properly, stop the weeding work and cover ( 106) and a lot of troubles to remove the foreign matter stuck between the blade 110, as well as there is a lot of problems, such as to bring down the work efficiency.

An object of the present invention is to provide a blade for mowing the grass, lumber and various foreign matters between the cover and the blade of the case during the weeding operation.

Blade for the present invention mowing blade for achieving the above object is characterized by forming a hook frame around the connection hole.

The blade 10 of the present invention by forming a hanging frame 26 having a diameter slightly larger than the outer diameter of the cover 24 around the connection hole 12, regardless of the type, the hanging frame 26 during weeding operations By blocking the gap between the cover 24 and the blade 10 to prevent a variety of foreign matter to be caught in the gap between the cover 24 and the blade 10, the life of the lawnmower to prevent overload There is no fear of reducing the rotational force of the blade 10 can be ensured that the weeding operation can be made smoothly, as well as to prevent the hassle and time loss for removing foreign matters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals are used to designate like elements in the drawings, It will be omitted for the sake of clarity.

Figure 2 is a perspective view of one embodiment of the present invention, Figure 3 is a cross-sectional configuration of one embodiment of the present invention, Figure 4 is a cross-sectional configuration of the use state of the present invention, the blade 10 of the present invention is a connection hole 12 The left and right blade portions 16 and 18 extend from the main body portion 14 having the cover 24 having a lower portion of the case 22 of the driving unit 20 around the connection hole 12 in the main body portion 14. Hanging frame 26 larger than the diameter of is configured to protrude.

In addition, in the case of the blade 10 in which the left and right blade portions 16 and 18 extend from the main body portion 14, the left and right blade portions 16 and 18 respectively form blades on both sides, and the blades are damaged when the blade on either side is damaged. (10) can be turned upside down to use the blade of the other side, in this case, the bottom surface of the blade 10 is also larger than the diameter of the cover 24 at the bottom of the case 22 around the connection hole 12 The frame 26 may be protruded.

5 is another embodiment of the present invention, the blade 10 of the present invention may be connected to the left and right blade portions 16, 18 on both sides of the main body portion 14, which is also connected to the main body portion 14 It is satisfied that the engaging frame 26 larger than the diameter of the cover 24 provided at the bottom of the case 22 of the driving unit 20 around the ball 12 is formed to protrude.

6 and 7 as another embodiment of the present invention, while protruding the hook frame 26 by the connection hole 12 in the main body portion 14 of the blade 10, the hook frame 26 May be formed by several discontinuous protrusions.

The blade 10 of the present invention clamps the nut 30 by allowing the driven shaft 28 of the drive unit 20 of the lawn mower to penetrate the connecting hole 16 of the main body 14 as shown in FIG. 4. When the blade 10 is fixed to the driven shaft 28 and the spline coupled between the inner, outer pressure plate 32, 34 is made to rotate along the driven shaft 28.

At this time, the cover 24 which is fixed to the lower end of the case 20 and maintains a slight gap from the blade 10 is located in the engaging frame 26 of the blade 10 so that the engaging frame 26 is the blade ( 10) and the gap between the cover 24 will be blocked so that weeds, weeds and other debris can be prevented from getting caught in the gap between the blade 10 and the cover 24 during the weeding operation do.

Therefore, in the present invention, weeds, lumber, and various foreign matters weeded during the weeding work may be caught between the blade 10 and the cover 24 so that there is no fear of overloading or disturbing the weeding operation. Will be.
