[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a gardening tool for removing weeds growing on a lawn.

[0002]

2. Description of the Related Art It is necessary to remove weeds mixed with turf grass in order to grow a lawn in a garden beautifully and robustly. In order to remove this weed, it is necessary to distinguish it from turfgrass so as not to damage the turfgrass. Therefore, conventionally, a bamboo spatula, weeding fork, weeding sickle, etc. are used to insert the weeds at the roots of the weeds. The method of pulling one by one was taken.

[0003]

[Problems to be Solved by the Invention] However, the method of finally removing weeds by using the above-mentioned equipment requires a worker to stand or sit, resulting in a heavy labor and a low work efficiency. There is also a drawback that the roots of turfgrass are damaged because the equipment is inserted into the soil at the base of weeds.

On the other hand, there are rakes and other tools for removing weeds for agricultural work, which are convenient for removing the weeds collectively when the weeds are spread and spread. , It is useless when weeds are mixed everywhere in the majority of turfgrass, such as grass weeds.

Therefore, it is an object of the present invention to provide a weed removing tool which puts less burden on an operator and can efficiently remove weeds mixed in the lawn.

[0006]

In order to solve the above-mentioned problems, the present invention proposes that the base of the comb teeth is attached to the tip of the instrument body attached to the tip of the handle in the direction orthogonal to the handle, A large number of metal needles constituting the above are attached to the attachment base at a certain angle with respect to the instrument body, and the gap between the metal needles is set to 0.8 to 2 mm.

[0007]

With the above-described weed removing tool, the operator holds the handle and inserts the comb teeth at the tip of the tool body into the grass surface near the ground surface at a shallow angle close to the ground, as if to comb the lawn. Then, move it as it is. Then, the root parts of the turf grass and the weeds enter the gaps between the metal needles of the comb teeth, and the turf grass slips through the gaps, but the weeds having a larger portion than the gaps are caught in the gaps between the metal needles and pulled out.

[0008]

EXAMPLE As shown in FIG. 1, the weed removing tool of the example is
An instrument body 2 made of a metal plate is fixed to the tip of the handle 1 with bolts 3. The tip of the instrument body 2 is 100-150 mm
It has a range of width.

An attachment portion 5 for the comb teeth 4 is provided at the tip of the instrument body 2. The attachment portion 5 is composed of a downward bent portion 6 provided on the tip edge of the instrument body 2 and an auxiliary plate 8 attached to the lower surface of the instrument body 2 with a screw 7. A mounting groove 10 (see FIG. 2) is formed by providing an inverted L-shaped bent portion 9 and facing the bent portion 5.

The comb teeth 4 attached to the attachment portion 5 are formed by arranging a large number of metal needles 12 in a row on the lower surface of a square bar-shaped base portion 11. This metal needle 12 has a height of 22 mm,
The diameter is 1.4 mm at the root part and 1.2 mm at the tip part, and the average diameter is 1.3 mm. Its tip has a roundness. The gap G (see FIG. 3) between the tips of the metal needles 13 is 1 mm.

The base 11 of the comb tooth 4 is inserted into the mounting groove 10 of the mounting portion 5, and the base 11 and the mounting groove 10 are inserted.
The wedge member 13 is driven from both sides in the gap between them to fix it without loosening.

The weed removing tool of the embodiment is as described above. When using the weed removing tool, an operator grips the handle 1 with both hands, and as shown in FIG. And insert it between the grass 15 at a relatively shallow angle α. At this time, the tips of the comb teeth 4 reach only the base of the grass 15 and are not inserted into the ground 14. It is not preferable to insert it into the ground 14 because it will damage the roots of the grass 15.

Next, when the worker combs the lawn and pulls the weed removing tool toward you (see arrow a), as shown in FIG. Since it is smaller than the gap G, it passes through the gap G, but most of the ordinary weeds 16 have a part thicker than the gap G described above. Thick parts include stems, nodes, branches,
For example, leaves, ears, and flower parts. These portions are caught in the gap between the metal needles 12 described above. The weeds 16 that have been caught are pulled out from the ground 14 as the comb teeth 4 move.

Further, among the weeds 16, the weeds whose stems grow in a crawling manner can be similarly pulled out because the stems of the crawling part are caught over several metal needles 12.

The types of the weeds 16 as described above vary depending on the environment of the lawn, but there are, for example, horsetail, chickweed, cod, psyllium, oxalis, chinensis and the like.

In the above embodiment, the average diameter of the metal needle 12 is about 1.3 mm, but this average diameter can be freely selected within the range of about 1.0 m to 1.4 mm. . In addition, the gap G between the tips of the metal needles 12
Can be freely selected within the range of about 0.8 to 2 mm. However, if this distance is less than 0.8 mm, it becomes difficult for the grass to pass, and there is a risk that the grass 15 will be damaged. If it exceeds 2 mm, small weeds 16 pass through the gaps, so that the efficiency of weed removal decreases.

Next, in another embodiment shown in FIGS. 6 and 7, the gap G'between the instrument body 17 having the comb teeth 4 similar to the above and the metal needle 12 is larger than the gap G in the above case. An instrument body 17 'having a slightly larger comb tooth 4'is back-to-back integrated with a screw 18 and fixed to one handle 1.

In this case, the comb teeth 4 and the comb teeth 4'are used upside down according to the condition of the weeds during use.

[0019]

As described above, according to the present invention, the gap between the metal needles forming the comb teeth is set in the range of 0.8 to 2 mm, so that the lawn can be combed to form a lawn. Mixed weeds can be distinguished from turfgrass and removed very easily without damaging the turfgrass. Also, because it has a handle, you do not need to stand or sit down, which makes weeding work easier. Further, since the comb teeth part scrapes off the root of the turf grass, oxygen delivery to the vicinity of the root is good, which is useful for turf growth and does not insert into the ground so that the root of the turf grass is not damaged.
