Description

      In the present invention, when weeding a field or garden, the conventional scalpel is only cutting the grass, and it is necessary to collect the cut grass by hand. There was a drawback. This plan was devised to solve the problem, and a bag was collected with a collection bag to collect the grass at the rear of the grass cutting blade, which made it possible to collect the grass in the collection bag at the same time as mowing the grass. There is something about sickle.

      The conventional “mowing tool” shown in the following document is an invention that digs up the root of a small grass and collects the grass in a collection box at the same time, but the grass root that grows up is strong, and as a tool for cutting grass stems and leaves, Not suitable. An ordinary weeding sickle is composed of a handle and a grass cutting blade, and it grabs the upper part of the grass and cuts it with the grass cutting blade.The cut grass is later scraped by hand or rake and manually put into a collection box. Although it was stored, it took more time to recover than cutting the grass and was troublesome. The present plan collects the troublesome grass collection in a collection bag attached to the grass cutting blade at the same time as cutting the grass, thereby omitting the work of collecting the cut grass.

Overall perspective view of the first embodiment of the present plan Overall perspective view of the second embodiment of the present plan Exploded perspective view of the first embodiment of the present plan Collection bag fixing structure explanatory diagram of the first embodiment of the present plan Mowing operation explanatory diagram of the first embodiment of the present plan

Hereinafter, the structure and use operation of the present plan will be described with reference to FIGS.
FIG. 1 is an overall perspective view of the first embodiment of the present plan, and FIG. 2 shows a second embodiment of the present plan. One mowing sickle is composed of two mowing blades and three patterns. The first embodiment is a flat blade sickle that is used when the leaves and stems are relatively soft, and the second embodiment is a saw that is used when the leaves and stems are relatively hard. Because the blade is a sickle, the only difference between the handle and the cutting angle of the grass cutting blade due to the characteristics of the grass cutting blade is that it is basically the same fellow mowing sickle, so the explanation of this plan will focus on the first example.
1 in Fig. 1 is a 2a flat blade of a mowing sickle, and a 3 handle is mounted at a substantially right angle to the 2a flat blade. In between, the back side of the 2-cutting blade is provided with a 4c bottom part of the core bar in close proximity to and parallel to the 2-cutting blade, and on the top side of the 2-cutting blade, above the 2-cutting blade 4b semi-circular part of the core bar extending in the direction is fixed to an 8-core metal fixing part which will be described in detail later, and the inlet side of the five recovery bags is sewn to each of the core bars.
FIG. 2 shows the second embodiment, which uses a 2b saw blade as the grass cutting blade as described above. The only difference is the attachment angle of the three patterns, and the structure for mounting the five collection bags is the same. Will be omitted. Next, the material of the core metal is strong in corrosion resistance, and a metal plating such as a chromium plating having a high corrosion resistance may be applied to a stainless steel wire or a high steel wire having a high rigidity. The material of the collection bag may be a synthetic fiber cloth material such as nylon fiber having good wear resistance and low water absorption, or a mesh member having a mesh of 5 mm or less may be used.
The length of the collection bag is preferably about 1 to 3 times the length of the grass cutting blade.
Next, a method for fixing the cored bar will be described with reference to FIGS. FIG. 3 is an exploded perspective view of the first embodiment, FIG. 4 is a detailed view for explaining a method of fixing the core metal of the collection bag,
The 7 through holes are provided on the rear side in the vicinity of the tip and the mounting portion of the 2-cutting blade, and a U-shaped hook is provided on the 4-core metal in accordance with the pitch of the 7 through holes. The size of the through hole is such that it can pass through the 4a hook portion of the core metal and is preferably an oval hole, but may be a round hole.
4a The hook part is a bent U-shaped cored bar, the inside dimension of the U-shape is the size that 6 clip wire can pass through, the height is 2 grass cutting blade rear thickness + 6 clip wire thickness more than To do. 5 The entrance side of the collection bag has a structure in which it is wrapped around the outer periphery of the core bar and stitched together, and the 4a hook portion is cut out and skipped. To install the 4-core bar, insert the 4a hook part into the 7 through-hole from the back side of the 2-cutting blade, and insert 6 clips inside the U-shaped groove of the 4a hook part protruding above the 2-cutting blade. Fix it. The 6-clip is a stainless steel wire bent as shown in the drawing. When the 6-clip is inserted, it will not come off unless it is pulled out by holding the 4-core metal with elastic deflection. A combination of the above structures corresponds to FIG. 1 or FIG.

From the above description of the structure, the description shifts to the description of the operating method. Fig. 5 is an explanatory diagram of the grass cutting operation of the first embodiment. If 2 grass cutting blades are applied to the root of the grass and 3 patterns are pulled quickly in the direction of →, the grass cuts and passes through the surface of 2 grass cutting blades and 5 collection bags Will slip into. However, if the grass is easy to bend, it can be easily reaped by supporting the upper part of the grass with the opposite hand with three handles. When moderate grass is collected in the 5 collection bags, the bottom of the 5 collection bags is picked and shaken upward so that the grass is discharged.
In addition, if the length of the grass is well above the 4b semicircle, pull out the 6 clip and pull out the 4 core metal in the direction of the back side of the 2 grass cutting blade. Can be used as mowing sickle. As can be understood from this description, it is important to determine the height of the 4a semicircular part, preferably about 1 to 2 times the 2 grass cutting blade, although the shape is not necessarily semicircular The shape may be rectangular, and the change in shape is interpreted as being within the scope of claims of the present invention.

Weeds in gardens and fields grow fast when there is a lot of rain, and even if they are cut with a weeding sickle, it is even more difficult to collect the grass. It must be moved, and it takes more time than mowing time, which is why it makes me hate mowing. In order to prevent such a cause, it is desirable to use the “sack mowing sickle with bag” of this proposal and collect the grass at the same time as mowing.
Furthermore, the collection bag of the “Mowing sickle with bag” in this proposal can be attached and detached with a simple operation. When cutting long cocoons, etc., it can be used as a normal mowing sickle by removing the collection bag. Mowing is easy, and it is useful for ordinary households and garden care specialists. If mass production is possible, it can be produced at a reasonable cost and with little burden.
We take pride in the invention that can be enjoyed by specialists and garden care specialists.

The whole mowing sickle with 1 bag, 2 grass cutting blade, 2a flat blade, 2b saw blade, 3 handle, 4 cored bar, 4a hook, 4b semicircle, 4c bottom, 4d connecting pipe, 5 collection bag, 6 clips , 7 through hole, 8 cored bar fixing part, ← Pattern pulling direction
