Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weeding tool suitable for caring for garden grass.

[0002]

2. Description of the Related Art Lawns in large parks or golf courses from homes are constantly eroded by weeds. Therefore, in order to prevent this, the herbicide spraying is regarded as a problem from the viewpoint of environmental pollution now, as soon as weed germination is found in the lawn, it is pulled out one by one and repels its reproduction. Is being done as the surest means.

As a weeding tool at this time, a small trowel scoop or a sickle tip, and a fork-shaped stick for root cutting are used.

By the way, some of the weeds that grow in the lawn have strong roots despite their low plant height, and when these leaf stalks are found in the lawn, lateral roots or burdock roots are already considerable. In many cases, when the stem is picked and pulled out, the overhanging lateral root causes soil around the root, and the surface lawn is returned to open a large hole in the ground. Moreover, the post-treatments such as filling the holes and hitting the grass are troublesome.

Therefore, even if the tip of a piercing stick is pierced into the stem of the weed and the root cutting is performed and then the root is pulled out, the root cutting is often incomplete. Even if digging may occur, or even if the root cutting is sufficient, the stem can be extracted smoothly, but on the other hand, the lateral root is left in the ground, so several days later It had a drawback that it did not have the effect of repelling weeds, such as germination again.

Also, among the weeds that occur in sandy areas,
Although the foliage is soft and weak, its fine roots spread widely on the ground surface, and when weeding, there are root nodules containing sand soil, or there are vines rooted on the surface of hard soil.

However, for such grasslands, effective weeding is necessary depending on the type of weeds and the breeding or soil conditions, such as root cutting or rooting and separation of soil and sand prior to weeding. It is desirable to choose some of the means.

[0008]

SUMMARY OF THE INVENTION To solve this,
Even weeds with lateral roots or burdock roots can pull or scrape the lateral roots and burdock roots as well as the main foliage of the weeds, minimizing the lifting of the soil surface of the roots and making the ground level after weeding. It is necessary to develop a weeding tool that can work to an unnecessary extent. Further, since this seed weeding tool is widely used in a wide range of places from general households to business such as golf courses, it is preferable that these weeding tools have high mass productivity.

[0009]

SUMMARY OF THE INVENTION In the present invention, however, one end of a piercing rod is sharpened so that it can be easily pierced into the ground, and the base of the end is pierced from one side area of the rod circumference. The hook needle is formed so as to spread toward the grip portion at the other end, and
The gist of the present invention is a weeding tool in which a piercing bar is slightly curved from the base toward the outside, and a large number of driving needles having a longer tip than the hook needle are arranged in the curved direction in the same direction as the hook needle.

The piercing bar is formed by punching into the shape of a bar core having a flat plate made of an iron plate or the like and each of the needles, and is folded in two at the center of the bar core in the axial direction. It is valid.

[0011]

By inserting the tip of a stick bar equipped with a hook needle into the soil of the root of the weed, the hook needle partly pushes over the base of the lateral root or slips past the burdock root and is pushed into the soil.

At this time, the hook needle portion which is provided only on one side of the tip of the piercing bar and which is widened toward the hand does not have resistance to the left for piercing the bar.

[0013] Next, as the stick is pulled out, the hook needle acts to pull the lateral root and burdock root while suspending the root and burdock root at the hook portion, so that the burdock root can be removed without applying any force to the leaf stem. By directly pulling out and pulling the lateral root toward the root of the stem, it is easier to pull out than in the soil, and these can be removed together with the foliage.

On the other hand, the driving needle provided on the part of the stabbing stick which is slightly curved is stabbed on the surface of sand or hard soil by hitting the piercing bar with the needle facing downward, and this is lightly forward. By pulling it up, you can loosen the ground surface and cut the lateral roots.

Next, the weeds can be collected together with the cutting roots by the reiki operation utilizing the driving needle.

In these operations, the curved construction of the piercing rod eliminates the adverse effect on the driving operation due to the protrusion of the hook needle at the tip, and at the time of raising the needle after driving, the hook portion contacts the ground. So that it can be used as a fulcrum,
It works effectively.

1 is a side view showing the basic structure of the present invention, and FIG.
Is another side view of the same structure, FIG. 3 is a side view showing another basic structure of the weeding tool of the present invention, and FIG. 4 is an explanatory view showing a work state of a basic constituent part of the weeding tool of the present invention together with a conventional weeding operation. The piercing rod 1 made of a hard material such as metal or synthetic resin has a total length of about 30 cm, which is easy to hold and operate while standing upright, and one end of which has a large diameter. A grip portion 2 of about 30 cm is provided, and the other tip is sharpened so that it can be easily stabbed into the soil, and hooks 3, 3, ... Are provided around a frame-shaped base several centimeters away from the tip. They are arranged in an anchor shape that is widened toward the grip portion 2.

The arrangement of the hook needles 3, 3, ... Is, in particular, approximately one side area of the rod periphery of the tip, as shown in FIG. When the material is made of metal, the one end with a needle diameter of 2 mm and a needle length of 22 mm is press-fitted into the hole 4 opened in the rod body (diameter 6 mm), and the fitting base is It is fixed by welding. When the whole is made of synthetic resin, it may be made slightly thicker than the previous shape and integrally formed with the main body.

On the other hand, the end of the piercing bar 1 on the side of the grip portion is constructed as a screw screw 4, which is removably screwed into a screw hole 5 provided in the grip portion 2.

FIGS. 5 and 6 are a side view and a plan view of an essential part showing an embodiment of the present invention. In addition to the tip structure of the piercing rod 1 in the basic constituent part, as shown in FIG. , The rod 1 is slightly curved, and the hook length of the hook needle 3, 3 is the same as that of the hook needle 3, 3 at the position of the curved portion which is about 5 to 6 cm away from the arrangement position of the hook needles 3, 3 toward the grip portion 2. A plurality of driving needles 6, which is about three times as many as 3, is provided. The number of the driving needles 6, 6, ... Is preferably larger than the number of the hooks 3 at the tip, and these needle tips are formed by widening in the lateral direction.

In consideration of mass productivity, the piercing rod 1 in this case is formed by first forming a flat plate made of an iron plate or the like in a state in which the rod core and each needle are expanded by punching or the like,
This is configured to be bent in the axial direction in two at the center (thin wire) of the rod core, and a large number of driving needles 6 ... Include the needle 6 and the rod core 7 before and after it. The flat plate having the expanded shape is folded in two, and is sandwiched and welded to the corresponding portion of the piercing bar 1. Further, the other end of the rod 1 is subjected to a screw cutting process for coupling with the grip portion 2.

As another processing means of the tool of the present invention, as shown in FIG. 7, each needle forming portion of the round bar is crushed into a plate shape by pressing means, and the crushed portion 8 is shown in FIG. By welding each needle part to the state, hook parts 3, 3, ...
Also, the driving needles 6, 6, ... May be formed.

According to the weed remover having such a configuration, when a weed scattered on the lawn is found, the tip of the weed is held by the gripping portion 2 from a direction perpendicular to the root of the weed. The piercing at this time is the hooks 3, 3 ...
Depth that can be fully hidden in the soil (depth beyond the lateral roots of weeds)
To the extent that

By the way, when the stems of the weeds are picked and pulled out, as shown by the upper arrow in FIG. 4, the force for pulling the stem A upward is applied to the root A'and the lateral root B in an obliquely upward acting force (dotted arrow target). ) Works. As a result, the stem A and the lateral root B are respectively caused to act, so that the soil around the root A ′ is dug up. Moreover, the burdock root C grows deep in the soil and resists the stalk A that is pulled up, so the weak stalk A breaks in the middle.

On the other hand, according to the above-mentioned work using the tool of the present invention, when the stick 1 is pulled out after the stick,
The hook 3 that once got over the lateral root B hangs the lateral root B,
The burdock root C will be entangled and it will rise. As a result, as shown by the solid line arrow in the figure, with the pulling out of the piercing bar, a lateral (base) acting force acts on the lateral root B with the previous suspension portion by the hook needle 3 as the point of action. Since the burdock root C is directly pulled up by the hook 3 on the other hand, the burdock root C is pulled out toward the root, so that the burdock root C is relatively easily removed and the soil around the root is not dug up.

Of course, even in this case, the lawn around the root may be lifted up. Therefore, as the work after removing the grass, it is sufficient to lightly press the soil surface after the removing with a shoe tip or the like, which is easy and easy. It's easy.

Further, depending on the type of weeds and the state of reproduction, it may be more efficient to scrape them than to individually remove them using the hooks 3, 3 ,. Work with the driving needles 6, 6 ...
That is, in the state where the piercing rod 1 is laid down in a direction parallel to the ground, the driving needles 6, 6 ...
By touching the tip of the rod (the needle tip of the hook needles 3, 3, ...) On the surface of the earth and using this as a fulcrum to lift the grip portion 2 lightly, the driving needles 6, 6 ,. Raise from inside.

As a result, the lateral roots of the weeds can be cut and the hard ground is slightly raised. Therefore, weeds can be easily pulled out, or the driving needles 6, 6 ...
Makes it easier to scrape.

According to this work, the surface of the ground is not excavated greatly, and the ground is well separated from the weed root,
It can suppress the surface roughness when weeding to a minimum.

On the other hand, when the screw rod 4 side of the piercing rod 1 is loosened and the piercing rod 1 is removed from the grip portion 2, a tool such as a conventional fork-shaped piercing rod is screwed to the grip portion 2 for use. You can also

[0031]

As described above, according to the weeding tool of the present invention,
With a long-handled stick, and because the hook needle was extended only on one side of the circumference of the stick, the hook needle does not create the resistance to the left when inserting the tip of the stick into the soil, and the root of the weeds. This can be pulled out together with the lateral roots and burdock roots of the weeds, and the soil at the root is not dug up, so it is easy to remove the soil and damage the lawn on the soil surface. No, etc., the weeding tool of the present invention is excellent in workability, and weeding work can be performed in an upright position, and the fatigue of the worker can be reduced by several steps as compared with conventional work, Moreover, since the destruction of the soil surface due to the work can be suppressed to a minimum, it is extremely effective in protecting and nurturing the lawn.

Since the stabbing rod is slightly curved and a driving needle is provided at this portion, the stabbing work of the stabbing rod by this can be performed without root cutting and scraping of the weeds without causing the ground to be damaged to a minimum. Depending on the type of weeds, the state of reproduction, etc., it is extremely convenient to be able to use these needles properly, and at the same time, it is inexpensive as equipment provided for golf-like facilities. It is useful for practical use.
