Description

TECHNICAL FIELD The present invention relates to a weeder for removing roots of weeds growing in gardens, parks, fields and fields of each household.

[Conventional technology]

A mowing sickle is commonly used as an instrument for weeding. When weeding with a sickle, a sickle is bent over to do the weeding work. At this time, the weeds are simply cut from the stem of the grass or from the root.

[Problems to be Solved by the Invention]

However, it is extremely painful to mow the grass for a long time while bending over with a sickle, and it is particularly difficult to remove weeds with large roots from the roots.

In addition, the weed fly, which grows together with the large-grown rice in the flooded rice field during the midsummer, has many seeds and adversely affects the growth of the rice, and thus must be removed. At this time, it is very troublesome to bend down the roots of the fly that grows while the tall rice is densely gathered, and to sort out the roots without pulling out the seeds and pulling out the roots. is there.

Therefore, the present invention has been made based on the above-mentioned circumstances, and it is possible to perform weeding work while keeping a person standing in a comfortable posture, and to easily pull out even the grass roots, as well as a weed in the rice field. The purpose of the present invention is to provide a weeding machine that enables convenient removal of the fly and improves work efficiency all at once.

[Means for solving the problem]

In order to achieve the above object, the weeding machine of the present invention is configured as follows.

The lower portions of a pair of operating rods that intersect each other and are pivotally attached to each other so as to be openable and closable are formed so as to project to the rear side, and the grass portions protruding from the lower ends thereof to the front side are arranged in parallel with each other. In both of the grass portions, the hanging point on the virtual extension line of each operating rod is set to be substantially the midpoint of each length of the grass portion. One of the two grass portions is vertically divided, and at least the divided front ends thereof are curved and connected. An elastic material is attached to the other grass portion. When the operating rod is opened / closed, the two grass portions are closed by the elastic material.
Although it is designed to be opened, the actuating rod has a biasing member that closes both nips.

Moreover, the following may be adopted as a configuration for closing and opening both the sandwiched portions.

That is, the operation lever is pivotally attached to the support rod having the grip portion at the upper end portion bent sideways so as to face the grip portion. A transmission member that interlocks with the operation lever is connected to one end of an oscillating body having an intermediate point pivotally attached to a lower position of the supporting rod. On the other end of the oscillating body and the lower part of the supporting rod, a pair of grass portions similar to the above, which project to the rear side and further project the lower end toward the front side, are formed on the virtual extension line of the supporting rod at a substantially midpoint. Side by side. Further, an urging member for separating the sandwiched portion attached to the oscillating body works.

Furthermore, the above-mentioned both grass portions may be configured as follows.

That is, the elastic material of the grass portion to which the elastic material is attached is formed with a notch surface on which the vertically divided grass portions abut, and the elastic material on the side to which the elastic material is attached is formed. The height positions of the lower ends of the portion and the sandwiched portion on the vertically divided side may be substantially the same.

〔Example〕

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

The weeder of FIG. 1 shows a typical embodiment structure of the present invention (hereinafter referred to as the first embodiment), in which a pair of operating rods 1 and 2 intersecting each other are mounted in a projecting manner at their intermediate portions. Piece 3,4
It is pivotally attached by a shaft 5 with an intervening member and is openably and closably combined. The lower parts of the operating rods 1 and 2 are largely bent rearward and bent, and further, the left and right grass portions 6 and 7 projecting forward from the bent lower ends are formed in parallel with each other. I am doing it. As shown in FIG. 2, each grass portion 6,7 has a hanging point B on the virtual extension line A of each operating rod 1,2.
It is designed to be approximately the midpoint of each length. Both sandwiches 6,
One of the grass portions 6 of 7 is divided by round bars 8 and 8 running vertically, and the front and rear ends of the round bars 8 and 8 are bent and connected to each other. An elastic material 9 such as rubber is attached to the other grass portion 7, and a notch in which the round bars 8 and 8 of the vertically divided grass portion 6 come into contact with the elastic material 9 respectively. Face 1
0 and 10 are formed, and the lower ends of the grass portion 7 on the side on which the elastic material 9 is attached and the grass portion 6 on the vertically divided side are located at substantially the same height in the horizontal direction. ing. Further, both ends of a spring 11 wound around the shaft 5 are hooked on the lower portions of the operating rods 1 and 2, respectively, and a biasing force acts in a direction of closing both the grass portions 6 and 7.

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

When removing weeds with the weeding device shown in the first embodiment, hold both handballs 12 and 12 in a standing posture and open the right and left grass portions 6 and 7 against the bias of the spring 11. Place it on the ground so that weeds may enter in between,
If you close 1, 2, the left and right weeding parts 6, 7 will close each other to sandwich the weeds, and while keeping the sandwiched state, use one end of the weeding parts 6, 7 as a fulcrum in front or forward The weeds can be pulled out from the roots by prying or pulling the weeds upward while sandwiching the weeds. At this time, since the spring 11 urges the two weeding portions 6 and 7 in the closing direction, it is easy to close the operating rods 1 and 2 when weeding the weeds, and even without applying a large force. A strong clamping force is generated, and since the midpoint of each grass portion 6,7 is located at the hanging point B on the virtual extension line A of the operating rods 1,2, the strong clamping force is sandwiched. It can be exerted evenly regardless of the part. Further, the lower end is located at substantially the same height, and the upper and lower round bars of the divided grass portion 6 are formed on the cutout surfaces 10 formed on the elastic material 9 of the grass portion 7.
Since 8 and 8 are in contact with each other, as shown in Fig. 6, in addition to sandwiching the weeds at the root, the upper part of the weed is bent and the contact area is large, so that a large pulling force is applied. Even if weeds with thick stems and thick roots are thick, they can be reliably pulled out from the roots.

In addition, when weeding out weeds growing in densely packed tall rice, find the fly from the top while standing and divide the rice at the front end of both sandwiched parts 6,7. While moving forward, the left and right weeding parts 6 and 7 are opened and closed to firmly pinch the fly, and after pulling it out, lift the fly that is being sandwiched by the spring 11 and lift one hand and waist. Operate the operating rods 1 and 2 in the opening direction of the weeding parts 6 and 7 to remove the fly from the weeding parts 6 and 7.
It moves to another open hand and carries it around, and weeds without spreading the seeds of the fly.

The weeder of FIG. 3 shows another example of the present invention (hereinafter, referred to as a second embodiment), which is the attachment position of both the weeding portions 6 and 7 at the lower end and its form (that is, The point that the hanging point B on the virtual extension line A of the support rod is formed to be substantially the midpoint of each length of the grass portions 6 and 7 is the same as in the first embodiment, The difference from the first embodiment is that the mechanism for closing and separating the two grass portions 6, 7 from each other is different.

That is, the upper and lower divided grass portions 6 on one side have the same configuration as that of the first embodiment and are attached to the lower portion of the supporting rod 13, and the other side portions arranged side by side on the lower portion 6 are attached. The sandwiched portion 7 provided with the elastic material 9 is attached to one end portion of an oscillating body 14 in which an intermediate portion is pivotally attached to a supporting rod 13. At the other end of the oscillating body 14, a transmission member 16 connected to an operation lever 15 pivotally attached to the upper part of the supporting rod 13 is attached. Further, a spring for urging the grass portion 7 attached to the rocking body 14 in a direction of separating it from the other grass portion 6.
17 is attached along the transmission member 16. Reference numeral 18 is a gripping portion for supporting the operation lever 15 at the same time when the operation lever 15 is actuated.

When removing weeds with the weeding machine of the second embodiment, the left and right weeding parts 6 which are opened by the biasing force of the spring 17 while holding the grip 18 and the operating lever 15 with one hand in a standing posture. Placed on the ground so that weeds can be inserted between them, and the operation lever 15 is pulled so as to approach the grip portion 18 side against the bias of the spring 17, and the transmission member 16 is pulled upward. And the weeding part 7 attached to the end of the rocking body 14 moves toward the weeding part 6 so that the weeding parts 6 and 7 close each other to sandwich the weeds, and the sandwiched state is maintained, It is a method of pulling out weeds from the root while twisting in the same manner.

In this way, the operation lever 15 is operated with one hand to open and close the sandwiched portions 6 and 7, and the weeding work is repeated.

In the case of weeding weeds, weeds are similarly clamped and pulled out, then lifted the sandwiched fly and release the finger from the operating lever 15 to release the spring.
The grass part 7 is opened by the urging force of 17, and the fly that was sandwiched between the grass parts 6 and 7 is transferred to the other open hand and held.
It works without spreading the seeds of the fly.

In the first and second embodiments, the round bars 8, 8 of the sandwiched portion 6 which are divided into upper and lower parts are bent at the front end and the rear end to be connected to each other, but as shown in FIG. Alternatively, only the front end thereof may be connected. Further, the notched surfaces 10 and 10 are formed in the elastic material 9 so as to increase the contact area with the grass portion 6 on the vertically divided side, but it is not necessarily limited to this and is shown in FIG. As described above, the elastic member 9 having a circular shape may be attached so that the elastic members 9 come into contact with the grass portions 6 on the vertically divided sides. Further, the elastic material 9 is not limited to rubber, and any elastic member having a toughness and a non-slip action is sufficient.

In the second embodiment, the upper and lower divided grass portions 6 attached to the lower portion of the supporting rod 13 and the other grass portion 7 attached to the end of the rocking body 14 are attached at the following positions. As a matter of course, they may be replaced with each other.
