Description

[Detailed Description of the Invention] The present invention relates to a mower used in the fields of agriculture and forestry, and more particularly to a manual mower whose cutting edge can be freely changed in direction.

There are two types of regular mowers: power-type and manual-type, and the most well-known manual type is a sickle, but the mower of this invention has new functions and effects not seen before. It is something that you have.

That is, in the lawn mower of the present invention, a long handle rod 1 and a cutting edge portion 2 having a plurality of forks 3 are connected by a movable connecting member 9, and the back surfaces of the forks 3, 3, 3... The belt-shaped blade body 4 having a wave blade 6 on one side and a knife blade 7 on the other side is attached perpendicularly to the fork 3, and is characterized by being able to cut and remove various vegetation with a small force. It is.

Hereinafter, the present invention will be explained in detail based on examples.

The lawn mower A consists of a long handle rod 1 and a cutting edge part 2.
It becomes attached.

The cutting edge part 2 consists of a band-shaped blade body 4 attached to the back side of a plurality of forks 3 whose tips are formed into sharp points,
A band-shaped blade body 4 is screwed onto the back surface of the fork 3 in a direction perpendicular to the fork 3 with a bolt 5.

The band-shaped blade body 4 has a front part with a wave blade 6.
The rear surface portion is formed into a knife blade 7, and several bolt insertion holes 8 are provided approximately in the center.
The direction of the belt-shaped blade body 4 can be changed depending on the type and size of grass.

The connecting member 9 between the handle rod 1 and the cutting edge portion 2 is formed into a ball-and-socket joint shape as shown in FIG. A spherical body 11 is fixed to the base 2a of the cutting edge portion 2, the spherical body 11 is inserted into the receiving member 10, and a presser cover 12 is screwed onto the spherical body 11.

Therefore, when changing the direction of the cutting edge part 2,
2 is loosened to hold the cutting edge part 2 in a predetermined direction, then tighten the pusher cover 12, press the sphere 11 against the receiving member 10 on the inner surface of the pusher cover 12, and fix the cutting edge easily. The direction of the portion 2 can be changed, and the direction can be freely changed not only in two-dimensional directions but also in three-dimensional directions.

As described above, the present invention is structured so that, for example, in a place where weeds with small stems are densely grown, the wave blade 6 of the band-shaped blade body 4 is moved toward the tip of the fork 3 as shown in FIG. If you swing the blade tip 2 toward the weed stem in the front-back direction as shown in Figure 1, the weeds will enter the gap S between each fork 3 and the adjacent fork 3, and the wavy blade 6 It is suddenly cut off. At this time, the effect of the wave blade 6 is exerted, and the weeds and stems are concentrated, so the weeds and stems can be collected by hand and cut like a sickle, so you can easily cut a large amount with less force than with a normal knife blade. You can cut the grass. Further, since the cut grass is placed on the fork 3, cutting and removal of the grass can be completed in one movement.

In addition, loosen the presser cover 12 of the connecting member 9 of the cutting edge part 2 and rotate the tip of the fork 3 by about 90 degrees from the position shown in FIG. If the blade is fixed in place, grass can be cut by swinging the blade edge 2 back and forth, left and right, or diagonally.

Next, when mowing weeds with relatively large stems or grass with hard stems, move the knife blade 7 of the strip blade 4 to the fork 3.
You can easily cut the grass by attaching it toward the tip and swinging the handle 1 back and forth, left and right, or diagonally in the same way as above.

As described above, according to the present invention, the band-shaped blade 4 is attached at a right angle to the forks 3, 3, 3..., and the direction of the forks 3, 3... is connected to the connecting member 9.
Because it is shaped so that it can be easily changed by operating the blade, it is possible to cut and remove various types of grass and small trees with a small amount of force, making it a valuable tool in the agricultural and forestry fields. It is widely used as a gift.
