Description

  The present invention relates to a device for taking grass (plants) such as weeds.

  In gardens, rice fields, flowerpots, and the like, grasses such as weeds grow naturally, so it has been common practice to remove these weeds regularly. In order to remove such grasses, in addition to the traditional manual weeding, we often use sickles and scissors, and recently we have used tools that sandwich and pull weeds. It is coming.

  However, weeding by these methods has caused the following problems.

  When weeding with a sickle, we cut the roots of the grass. For this reason, nuclei are generated again from the cut portions of the roots remaining in the soil, and leaves are grown again using the regenerated nuclei as the starting point of growth. Therefore, weeding with a sickle, rather than exterminating weeds, on the contrary, activates the reproductive ability and increases weeds.

  In the weeding using "鍬", we basically dig up the soil and embed the weeds in the soil, but this digging up of the soil takes a lot of time and exhausts our physical strength. Therefore, weeding using “鍬” has a problem in terms of workability. In addition, similar to the weeding using the “sickle”, the grass roots are left in the soil, resulting in an increase in weeds.

  In addition, there are the following problems in so-called manual weeding and weeding using an instrument that sandwiches weeds.

  Plants such as weeds have evolved so that they can be easily cut by pulling on the leaves, so that herbivores can survive if they eat them. That is, there is a problem that even if the “leaf” of the weed is pulled manually by weeding, it is easily cut at the leaf portion and the entire weed including the root cannot be uprooted.

  In addition, plants such as weeds have evolved so that when a herbivorous animal bites and pulls, it receives a strong stimulus and easily cuts in the middle of the root. In other words, when a herbivore bites a weed, the plant has evolved so that at least a portion of the root of the weed remains in the soil (so that it can be propagated thereafter). Therefore, when weeding using a tool that sandwiches weeds, the roots are damaged by stimulation when the weeds are pulled strongly, and the roots are easily cut. Then, after several days, nuclei are generated again from each of the remaining roots in the soil, and leaves are grown again with the regenerated nuclei as starting points of growth. Therefore, weeding using such a device has a problem of increasing weeds.

  In view of the above-described problems of the prior art, an object of the present invention is to provide a weeding tool that can easily and reliably uproot plants such as weeds to be controlled.

The above purpose is
A weeding tool for taking grass that has sprouted and grown from a nucleus consisting of a part that was a seed, and has a piercing part that can be pierced into the soil,
The piercing portion is
An encircling part that can surround the root of the grass with the piercing part pierced into the soil,
A hook that can hook the core of the grass (part connected to the root of the grass) in the process of pulling out the piercing part from the soil,
Achieved by a weeding tool with

The piercing portion is configured to be openable and closable,
By sticking into the soil in the open state, it is possible to take in the roots of the grass in the gap inside the surrounding portion, and by pulling out from the soil in the closed state (and the state in which the grass roots are taken in), It is possible to lead towards the nucleus of.

  Further, the hook portion of the piercing portion is configured by a gap (for example, a narrow gap) that leads to a space surrounded by the surrounding portion.

  In plants such as weeds, as shown in the right end of FIG. Its roots grow straight down under the seed, and when it eventually stabilizes, the leaves extend above the seed to the ground. And the nucleus (the part that was the seed) that is the center of the growth swells and many leaves come out. In other words, the roots and leaves begin with a “nucleus”, and the nucleus is characterized by being harder and larger than other parts (such as roots). The inventor of the present application has paid attention to this point and has created the present invention. And the effect achieved by the weeding tool of this invention is as follows.

When weeding, as in the past, if you grab (or pinch) the leaf easily and pull it, it will break there, and similarly, if you grab the root (or pinch) and pull it, it will cut there . In this case, rather than exterminating the weeds, on the contrary, the ability to reproduce the weeds is activated, resulting in an increase in the weeds.
Therefore, in the present invention, the entire root is searched and surrounded and pressed by the pierced portion pierced into the soil so as not to grab or pinch the root of the weed. Then, the pierced portion is pulled out while surrounding the root of the weed, and in the process, the nucleus of the weed is hooked in the gap of the hook portion. The “nucleus” caught on the weeding tool is harder, more rugged, and larger in diameter than the other parts, so that weeds connected to it can be uprooted by pulling it up.
Therefore, weeding using a weeding tool having such characteristics eliminates the risk of damaging or cutting the root of the weed to be removed, and also eliminates the need to remove only the leaves. It can be surely uprooted.

  Moreover, it is common that the root grows straight as shown in FIG. 1 regardless of whether it is a two-leaf from a seed or a large-grown grass. In the present invention, paying attention to this point, the piercing portion is configured to be openable and closable. By piercing into the ground with the piercing part open, you can hold down the entire grassroots without having to look carefully. In other words, in the present invention, the range of capturing the roots of the grass is extremely wide, so even if the grass to be exterminated is clustered, by capturing these nuclei reliably, pulling them together and pulling them together, It can be uprooted at once. In addition, even if the grass grows in a state of being connected to each other through roots in the soil, the roots can be collectively surrounded by the weeding tool of the present invention. It is possible to hook up a lot of nuclei that connect to the roots and gather up the grass that has grown, and uproot it.

  In addition, the weeding tool of the present invention does not grab a single point of the grass root, so it is not necessary to concentrate on a troublesome work such as “grabbing a single point”. In other words, it is sufficient to appropriately pierce a place where grass roots are likely to be stretched, so that weeding work can be carried out efficiently and with less labor.

  Further, the structure of the tip side (the stab portion) of the weeding tool of the present invention can search the depth of the root of the grass, for example, like a crane's mouth, and it can also be used for many roots, such as the tip of a spider. Is configured to capture. By constructing the piercing part like a bird's mouth in this way, it is possible to capture not only one grass but also multiple grasses regardless of the size without cutting the roots of the grass at the same time. Can be advanced.

  Moreover, even if there is a plant that has failed and has had its leaves cut, it can be rooted by hooking the nucleus of the grass by piercing it into the soil using the weeding tool of the present invention.

In addition, since a plant like a kabami has a wide range of roots, it is easily cut at the leaf portion just by pulling the leaf from the ground surface. In other words, simply pulling a part of a leaf or root easily cuts that part and cannot be uprooted. And if you leave the cut and left as it is, buds will emerge in a few days from there, so normal weeding will result in an increase in grass.
On the other hand, according to the weeding tool of the present invention, it is possible to uproot the grass without cutting it halfway. In the unlikely event that a grass root is cut off, it can be uprooted by piercing the weeding tool again to find another root and pulling up the nucleus along that root. Therefore, when the weeding tool of the present invention is used, weeds can be easily exterminated, and it does not result in an increase in weeds. In addition, in the above-mentioned case, the ox was taken as a specific example, but the same applies to the case of exterminating other plants such as agaric.

  Even if a large number of grasses have already been taken, there may still be grass roots in the soil, and if they are left unattended, weeds will grow again from there. Therefore, even after a large number of grasses have already been taken, by using the present invention, it is possible to easily and surely remove the grass remaining in the soil by uprooting it.

  In addition, the use place of the weeding tool of the present invention is not particularly limited, for example, work in a place where weeds have grown over a narrow interval, a narrow place such as a flower pot, or a place where large and small weeds have gathered. It can be used for weeding in various places.

  In addition, the weeding tool shown in the attached drawing of this application is an example to the last, Comprising: The structure of this invention is not limited to this. For example, by making the weeding tool long so as to have a long handle between the handle at hand and the piercing portion at the tip, it can be used without bending down. As a result, for example, when weeding in a rice field, it is possible to achieve a special effect that the work can be easily advanced without placing a burden on the waist.

  Further, by using the present invention, a special effect is achieved that the hands are not soiled in the weeding operation.

It is a figure which shows roughly the structure of plants, such as a weed, and the process of the growth. It is a perspective view which illustrates the whole weeding tool of this invention. FIG. 3A is a plan view showing a state where the stab portion of the weeding tool is opened (open state), and FIG. 3B is a plan view showing a state where the stab portion of the weeding tool is closed (closed state). FIG. It is an enlarged view which shows the stab part of the weeding tool shown in FIG.3 (b). It is sectional drawing which shows the cross-sectional shape of the arm which comprises the stab part of a weeding tool. 5A is a cross-sectional view taken along the line VV in FIG. It is a figure which shows a mode that the weeds which are control targets are uprooted using the weeding tool of this invention. It is a figure which shows a mode that several weeds are put together and rooted up using the weeding tool of this invention.

  The weeding tool according to the present invention is a weeding tool for removing grasses such as weeds that have grown rooted and germinated from a plant 71 as shown in FIG.

  As shown in FIG. 1, in the plant 7 such as weeds, the seeds swell during the growth process, and roots 73 appear first. In other words, in the process of growth, when the root 73 first grows straight toward the bottom of the seed and eventually stabilizes, the leaves extend to the top of the seed to the ground. Then, the nucleus 71 which is the center of the growth swells and many leaves 75 come out.

  That is, as shown in FIG. 1, all the roots and leaves of plants such as weeds have the nucleus 71 (the part that was originally a seed) as the beginning of growth, and the nucleus 71 is another part such as the root. It is characterized by being harder and larger than

  The present invention is an idea created by paying attention to the point that the nucleus of a plant such as weeds (the part that was originally a seed) is harder and larger than the other parts.

  It should be noted that the present invention is not a device that grabs or pulls plants (roots and leaves) such as weeds to be controlled, and is not an instrument that cuts plants. I want to be.

(Configuration of weeding tool)
Hereinafter, based on FIGS. 2-5, the specific structure of the weeding tool used in order to uproot the above weeds is demonstrated.
FIG. 2 is a perspective view showing the entire weeding tool 1.
FIG. 3A is a plan view showing a state where the piercing portion 3 of the weeding tool 1 is open (open state), and FIG. 3B is a state where the piercing portion 3 of the weeding tool 1 is closed (closed state). FIG.
FIG. 4 is an enlarged view showing the piercing portion 3 of FIG.
5A is a cross-sectional view taken along the line VV in FIG.

  Note that the weeding tool illustrated in the accompanying drawings is merely an example, and various forms and modifications can be employed within the scope of the claims.

The weeding tool 1 is mainly composed of
-The handle 2 which is a part held by the weeding operator,
・ Puncture part 3 capable of opening and closing similar to tools such as scissors and pliers,
have.

  In the present embodiment, finger grips 21 and 22 through which the operator's fingers can be passed are formed on the handle 2. The piercing portion 3 can be opened and closed in the same manner as a tool such as scissors or pliers by separating and approaching the shafts 23 and 24 while the operator's finger is passed through the finger passages 21 and 22.

As shown in FIG. 2 to FIG.
A surrounding portion 4 that can surround a large number of grass roots over a wide range when the piercing portion 3 is pierced into the soil;
-It has the hook part 5 which can hook the "nucleus" connected to the grass root in the process of extracting the stab part 3 from the soil.
The latter hook portion 5 is composed of a long and narrow gap as shown in FIG. 4. Of course, a single nucleus can be hooked in this gap, and a large number of cores can be hooked at once. is there.

  The surrounding portion 4 is composed of two arms 41 and 42 that rotate about a rotation shaft 40. The arms 41 and 42 have a role of enclosing from both the left and right sides of the grass root. As shown in FIG. 4, the two arms 41 and 42 constituting the surrounding portion 4 are formed so that at least the inside thereof is curved. By forming the curve in this way, when the piercing portion 4 is pierced into the soil and closed, it can be taken into the inner space (the gap 43 between the two arms) without damaging the roots of the weeds. Become. Moreover, the front-end | tip part of the arms 41 and 42 has a rounded shape (that is, it is not sharp). In the state where the piercing portion 3 is closed, the rounded tip portions of the arms 41 and 42 are in point contact with each other. Thus, by forming the tip portions of the arms 41 and 42 in a round shape, it is possible to prevent the tip portions from damaging the grass roots during the weeding operation.

  The two arms 41 and 42 constituting the surrounding portion 4 are not formed with “blades” so as not to damage or cut the roots of the plant. That is, as shown in the cross-sectional view of FIG. 5A (cross-sectional view along the line VV in FIG. 4), the arms 41 and 42 have an R-shaped cross-sectional shape with rounded edges facing each other. It is formed to have. In addition, as shown in FIG.5 (b), you may form the arms 41 and 42 in a cross-sectional circle shape. As shown in FIG. 5 (a) or (b), the portion where the arms 41 and 42 face each other has a rounded shape, so that when the piercing portion 3 is closed in the soil, the space between the arms 41 and 42 The soil will escape quickly. Therefore, when the root is taken into the inside of the piercing portion 3 (gap 43), the soil between the arms 41 and 42 is not disturbed by the soil between the arms 41 and 42. In addition, since no soil adheres between the arms 41 and 42, it is not necessary to manually remove the soil every time it is inserted or removed, and the grass extraction work by the piercing portion 3 can be repeated quickly and again. it can. That is, the weeding work by repeating the insertion and removal can be promptly advanced without any delay.

In addition, as shown in FIG.5 (c), when the shape of the arms 41 and 42 is formed in the cross-sectional rectangular shape, since soil will be pinched | interposed between the arms 41 and 42, The closing of the arms 41 and 42 is disturbed. Further, every time the grass is extracted, it is necessary to manually remove the soil adhering between the arms 41 and 42. Therefore, there arises a problem that the extraction of the grass cannot be repeated quickly.
In addition, as shown in FIG. 5 (d), when the blades are formed by sharpening the edge portions of the arms 41, 42, the roots sandwiched between the arms 41, 42 when the piercing portion 3 is closed. Will be hurt. Therefore, as described above, there is a problem that damaging grass roots activates grass propagation ability.
However, as described above, in the present invention, the arms 41 and 42 are formed such that the facing edge portions have a rounded R-shaped cross-sectional shape, so that the above-described problem does not occur.

  As shown in FIG. 4, the hook portion 5 includes a space surrounded by the surrounding portion 4 (a gap 43 sandwiched between the two arms 41 and 42) and a continuous narrow gap. The hook portion 5 formed of an elongated gap is formed inside the distal ends of the arms 41 and 42 in a closed state.

The piercing portion 3 including the surrounding portion 4 and the hooking portion 5 described above has a shape that can be pierced into the ground like a bird's beak. At the time of weeding, the piercing portion 3 is used to be pierced into the soil or pulled out from the soil.
In the case of birds, when the beak is closed in the water, the water in the meantime escapes to the side, but when the beak is closed in the soil, the soil gradually gets caught between the beaks ( In other words, the soil does not escape from between the beaks). Therefore, when a bee is inserted into the soil, the birds try to remove the soil sandwiched between the bees by repeatedly shaking his head left and right. However, in the present invention, as shown in FIGS. 5 (a) and 5 (b), the facing portions of the arms 41 and 42 are formed in a curved convex shape, so that no soil is caught like a bird's beak. By closing the arms 41 and 42, the effect that the soil between them automatically escapes to the side is achieved.

The piercing part 3 is configured to be openable and closable.
By sticking the piercing portion 3 into the soil in the open state (the state shown in FIG. 3A), it is possible to take in grass roots and the like inside the surrounding portion 4.
By pulling out the piercing portion 3 from the soil in the closed state (the state shown in FIG. 3 (b)), it is possible to maintain the state of surrounding the grass roots. Further, by pulling out the piercing portion 3 in this way, the surrounding portion 4 is guided toward the nucleus along the string-like root, and the nucleus of weed (see FIG. 1) is hooked on the hook portion 5 formed of a narrow gap. It becomes possible.

(Weeding method)
Next, a weeding method using the weeding tool configured as described above will be described with reference to FIG.
FIG. 6 is a diagram showing a state in which the weeds to be controlled are uprooted using the weeding tool 1. An enlarged view of the weeds to be controlled is as shown in FIG.

  First, as shown in FIG. 6 (a), with the piercing portion 3 kept in an open state, the piercing portion is pierced into the soil toward the root of the weed 7 to be controlled. In the process, the weed root 73 is taken into the gap between the two arms 41 and 42. As described above, since the blades are not formed on the two arms 41 and 42, there is no possibility that the piercing portion 3 damages or cuts the weed root 73 during the piercing process.

  As shown in FIG. 6 (a), the pierced portion 3 is pierced into the soil, and the entire root of the weed is taken into the gap between the two arms 41, 42. Press in. When the piercing portion 3 is closed, the rounded tips of the arms 41 and 42 are closed in contact with each other, and the soil escapes between them as shown in FIG. 5 (a), so that the entire root of the weed to be weeded is the piercing portion. Surrounded by arms 41 and 42. Thereafter, even if the piercing portion 3 is pulled out, the root does not come out from there.

  Subsequently, in a state where the piercing portion 3 is closed, the piercing portion is pulled out from the soil. In the process, the piercing portion 3 is guided upward along the surrounding root 73 with a feeling of being transmitted through a string. Then, in the process of pulling out from the soil, the piercing part traces the surrounding roots, and eventually the nuclei that are harder and larger than the root (the part that was originally a seed) are pierced part 3 as shown in FIG. 6 (b). It is hooked on the hook portion 5 on the front end side.

  As shown in FIG. 4, the hook portion 5 is composed of a narrow gap. On the other hand, the nucleus of weeds is larger than the gap of the hook portion 5, so that the nucleus cannot pass through the gap of the hook portion 5. Therefore, as shown in FIG. 6 (c), the core and the portion connected to the core are pulled out from the soil by pulling out the piercing portion 3 as it is. As shown in FIG. 4, the relatively large grass core is caught in the wide gap portion of the hook portion 5, and the small grass nucleus just germinated is closer to the narrow portion near the tip of the hook portion 5. It is supposed to be caught in.

  Since the nucleus of the plant (see Fig. 1) is characterized by being harder and larger than the other parts, pulling up the core part with the pierced part 3 pulled up, the whole weed in the shape of a root Can be pulled out. That is, unlike conventional grass weeds, the roots of weeds are not left in the soil, so that nuclear regeneration can be prevented.

  As described above, in the present invention, the entire root is searched and surrounded and pressed by the pierced portion pierced into the soil so as not to grasp the root of the weed. Then, the pierced portion is pulled out while surrounding the root of the weed, and in the process, the nucleus of the weed is hooked in the gap of the hook portion. Since the “nucleus” caught on the weeding tool is harder and stronger than the other parts, weeds can be uprooted by pulling that part. Therefore, weeding using a weeding tool having such characteristics eliminates the risk of damaging or cutting the root of the weed to be removed, and also eliminates the need to remove only the leaves. It can be surely uprooted.

  In the above-described embodiment, the procedure for extracting one weed has been described as a representative example. However, in the weeding using the present invention, a large number of weed nuclei are gathered at once as shown in FIG. It is also possible to hook them and pull them out at once. In other words, in the present invention, it is not particularly necessary to concentrate nerves on extracting one weed, and if we appropriately pierce a place where weeds are likely to cluster, weeds at that place can be gathered and uprooted at once. .
