Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weeder for pulling out weeds, including their roots, growing in gardens, parks, fields, and fields of households.

[Conventional technology]

Grass cutting sickles are commonly used as tools for removing weeds. When cutting weeds with a mowing sickle, the user bends down to cut the grass, and in this case, the grass is simply cut from the stem or root.

[Problem to be solved by the invention]

However, mowing with a mowing sickle while bending over for long periods of time is extremely tiring, and it is especially difficult to pull out weeds with large roots.

In addition, in a rice field flooded in midsummer, the weed millet that grew along with the large rice plants had many seeds (for farmers, this had a negative impact on the growth of the rice plants, so they had to be removed).

At this time, it is a very tedious task to bend down at the base of the millet that grows among the tall rice plants, and while sorting through the millet, pull out the roots together without scattering the seeds. be.

The present invention was developed based on the above-mentioned circumstances, and it allows a person to weed while standing in a comfortable position, and it also allows for easy weeding down to the roots of the grass, which is a nuisance to weeds in the fields. To provide a weeding device which can conveniently remove even barnyard grasses and improve work efficiency at once.

[Means to solve the problem]

In order to achieve the above object, the weeder of the present invention is constructed as follows.

The lower portions of a pair of operating rods that intersect and are pivotally connected to each other so as to be openable and closable are formed so as to protrude rearwardly, and furthermore, wedge portions protruding forwardly from each lower end are arranged in parallel with each other. Both of these webbing portions are designed such that the hanging point on the imaginary extension line of each operating rod is approximately the midpoint of each length of the webbing portion. One of the two isolating parts is divided into upper and lower halves, and at least the front ends of the two halves are curved and connected. When the operating rod is opened and closed, the two clamping parts are closed and separated from each other via the resilient material, and the operating rod is actuated by a biasing member that closes the two clamping parts. .

Moreover, the following structure may be used to close and open both the slits.

That is, the operating lever is pivotally attached to a support rod having a grip portion at its upper end portion that bends laterally so as to face the grip portion. A transmission member interlocked with this operating lever is connected to one end of a swinging body whose intermediate point is pivoted at a lower position of the support rod. Then, at the other end of the swinging body and at the lower part of the support rod, a pair of trapezoids similar to those described above, each overhanging to the rear side and further protruding to the front side at the lower end, are placed so that the imaginary extension line of the support rod is at approximately the midpoint. Install them in parallel in this way. Further, a biasing member attached to the rocking body that opens the slat part is activated.

Furthermore, the above-mentioned two-legged parts may have the following configuration.

In other words, a spring material is attached to one of the grass parts, and a cutout surface is formed on the spring material, on which each of the split grass parts comes into contact, and the grass part to which the spring material is attached and the split grass part are connected to each other. The height positions of the lower ends of and may be made to be approximately the same as each other.

〔Example〕

Hereinafter, embodiments of the weed cutter according to the present invention will be specifically described with reference to the drawings.

The weeder shown in FIG. 1 is a typical implementation structure of the present invention (hereinafter referred to as
This is called the first embodiment. ), a pair of actuating rods 1 and 2 that intersect with each other have mounting pieces 3 and 2 protruding from their intermediate parts.
It is pivotally connected by a shaft 5 with a shaft 4 interposed therebetween, and is a combination that can be opened and closed freely. The lower portions of the operating rods 1 and 2 are bent and protruded rearward, and the left and right wedge portions 6 and 7 that protrude forward from the lower ends of the respective bends are interconnected so that they are parallel to each other. It is. As shown in FIG. 2, the hanging point B on the virtual extension line A of each operating rod 1, 2 is approximately the midpoint of the length of each of the interlocking sections 6, 7. It looks like this. One of the two isolating parts 6, 7 is divided by round rods 8, 8 running vertically, and the front and rear ends of the round rods 8, 8 are curved and connected to each other. There is. A resilient material 9 made of rubber or the like is attached to the other wedge portion 7, and the resilient material 9 has cutout surfaces 10 and 10 on which the round bars 8, 8 of the divided wedge portion 6 come into contact, respectively. At the same time, the lower ends of the weeding section 7 to which the resilient material 9 is attached and the divided weeding section 6 are at approximately the same height in the horizontal direction. Furthermore, both ends of a spring 11 wound around the shaft 5 are hooked to the lower portions of each of the operating rods 1 and 2, and bias is applied in a direction to close the two latches 6 and 7.

In the figure, reference numerals 12 and 12 indicate grip balls attached to the upper ends of the operating rods 1 and 2.

When pulling out weeds with the weed remover shown in the first embodiment, hold both grip balls 12 and 12 in a standing position and open the left and right weed parts 6 and 7 against the bias of the spring 11. Place the weeds on the ground with the weeds between them, and then close both operating rods 1 and 2, and the left and right weed trapping parts 6 and 7 will close together to trap the weeds and keep them in a pinched state. Hasakusabe 6
, 7 can be used as a fulcrum and the weeds can be pulled out from the roots by levering them forward or toward the front, or by pulling the weeds upward while holding them in place. At this time, since the spring 11 is biased in the closing direction of both weed weed parts 6 and 7, it is easy to close the operating rods 1 and 2 when clamping the weeds, without applying a large force. A strong clamping force is generated, and since the midpoint of each clamping part 6, 7 is located at the hanging point B on the imaginary extension line A of the operating rods 1, 2, the strong clamping force can be clamped. In addition, since the lower ends are at approximately the same height position, the grass part 7
The upper and lower round rods 8, 8 of the split weed section 6 come into contact with the cutout surfaces 10.10 formed in the resilient material 9, so that the weeds can be removed at their roots as shown in FIG. In addition to pinching, the upper part is bent and the pinching area is large, so it is possible to apply a large pulling force, and even thick-stemmed weeds with large roots can be pulled out from the roots. (It is something that can be done.

In addition, when pulling out weed millet growing between densely grown rice plants, find the millet from above while standing, and separate the rice plants at the front ends of the weeds 6 and 7. The device moves forward while moving forward, and firmly grasps and pulls out the barnyard grass by opening and closing the left and right clamping parts 6 and 7. After pulling it out, it lifts the barnyard grass that is still being held in place by the spring 11, and uses one hand and waist to pull it out. Use the lever to operate the operating rods 1 and 2 in the direction of opening the clamping parts 6 and 7, transfer the barnyard millet that was being clamped by the clamping parts 6 and 7 to the other hand, and remove the seeds of barnyard grass. This allows you to weed without scattering any weeds.

The weeding device shown in FIG. 3 shows another example of the present invention (hereinafter referred to as the second embodiment), and the weeding device shown in FIG. The point that the hanging point B on the virtual extension line A of the support rod is formed so as to be approximately the midpoint of the respective lengths of the support rods 6 and 7 is the same as in the first embodiment, but The difference from the first embodiment is that the mechanism for closing and opening the two interlocking parts 6 and 7 from each other is different.

That is, one of the split weed sections 6 has the same form as in the first embodiment and is attached to the lower part of the support rod 13, and the other of the split weed sections 7 arranged in parallel to the split weed sections 6 are as follows: It is attached to one end of a swinging body 14 whose middle portion is pivotally connected to a support rod 13. Oscillator 1
At the other end of 4 is an operating lever 1 pivotally connected to the upper part of the support rod 13.
The transmission member 16 connected to 5 is the attachment. In addition, a spring 17 that biases the clamping part 7 attached to the rocking body 14 in the direction of separating it from the other clamping part 6 is connected to the transmission member 16.
It is attached along. Note that reference numeral 18 designates a grip portion for supporting and holding the operating lever 15 at the same time as the operating lever 15 is operated, and is provided by being bent laterally at the upper end of the support rod 13 so as to face the operating lever 15.

When removing weeds with the weed remover of the second embodiment,
While standing, hold the grip part 18 and the operating lever 15 with one hand, and place the weeds on the ground between the left and right weed parts 6 and 7, which are opened by the bias of the spring 17. When the operating lever 15 is pulled toward the grip portion 18 against the bias of the spring 17, the clamp portion 7 attached to the end of the swinging body 14 is pulled upward via the transmission member 16. moves in the direction of the weed trap 6, the weed traps 6 and 7 close together to pinch the weed, and while maintaining the pinched state, pull the weed out from the root by prying it like a lever. .

In this way, the weeding operation is repeatedly performed by operating the operating lever 15 with one hand to open and close the weeding sections 6 and 7.

In the case of weeding weeds, after gripping and pulling out the weeds in the same way, lift the clamped barnyard grass, release your finger from the operating lever 15, and use the biasing force of the spring 17 to weed the weeds. Open section 7, transfer the millet that was being held between the clamping sections 6 and 7 to the other hand, and scatter the millet seeds.

In the first and second embodiments, the round bars 8, 8 of the split grass part 6 have their front and rear ends curved and connected to each other, but as shown in FIG. They may be connected. In addition, the notch surface 10.10 is formed in the resilient material 9 to increase the area of contact with the split grass part 6, but the invention is not limited to this, and as shown in FIG. It is also possible to have a structure in which the resilient material 9 is attached and hits each of the split grass sections 6. Furthermore, the elastic material 9 is not limited to rubber, and any elastic material that is strong and has an anti-slip effect is sufficient.

In the second embodiment, the mounting positions of the split bracket part 6 attached to the lower part of the support rod 13 and the other bracket part 7 attached to the end of the swinging body 14 are exchanged. Of course, you can do it.
