Description

Description: TECHNICAL FIELD The present invention relates to a grass root pruning machine for extracting strongly rooted weeds growing in gardens, parks, fields or fields of each household, together with various major roots.

[Conventional technology]

Although there is a sickle as an agricultural tool for cutting weeds, the roots still remain after cutting with this sickle, so that weeds grow again after cutting, and it is not possible to completely eradicate the weeds. Therefore, as a means of eradicating weeds, it is common practice to remove the weeds with all the roots by human hands.

[Problems to be Solved by the Invention]

However, the work of plucking each weed one by one in an unnatural posture in which a person bends down for a long time is extremely painful, and the work efficiency is also very poor.
For example, weeds with wide roots are difficult to pull out. If you forcibly pull this out, the soil around the root will also be removed and a large hole will be made, so there was the trouble of having to refill the hole one by one.

Therefore, the present invention has been made based on the above circumstances, and enables the weeding work to be performed in a comfortable posture, and moreover, the weeds can be efficiently efficiently removed from one to another by simple operation. The purpose is to provide a grassroots pruning machine that can be pulled out together.

[Means for solving the problem]

A grassroots pruning machine according to the present invention for achieving the above-mentioned object pivotally supports a pair of operating rods in an X shape at a lower portion thereof with a central pin, and secures opposing weed plates to the lower ends of the operating rods. , A plurality of comb tooth pieces curved in opposite directions are staggered in the lower part of both weed plates, and a blade-like portion is formed at the tip of each comb tooth piece, and each operation rod is attached to the other operation rod. Providing a projecting piece reaching the back side of the weeding board, the base end of a supporting piece having a cleaning piece having substantially the same width as the weeding board is pivotally supported at the tip of the projecting piece, and the cleaning piece is sandwiched by a spring. It is abutted on the back side of the grass plate, and the cleaning piece slides up and down on the back side of the grass plate when the grass plate is opened and closed by opening and closing the operating rod. It is a thing.

[Action]

In the grass root pruning machine according to the present invention, by closing the upper part of the pair of operating rods, the weeding plates provided at the lower ends of the two operating rods hold the weeds, and the lower comb teeth of both the weeding plates are misaligned. To prevent downward deviation when weeds are pulled out. Further, at that time, the comb teeth of both the weeding boards cut into the roots of the weeds while cutting the widely spread roots along the edges thereof. Furthermore, when the cleaning piece that is in contact with the back side of each weeding board discards the weeds that are held by the weeding board, the back side of the weeding board extends from the top to the bottom as the spacing of the weeding boards increases. Slide to remove weeds and mud attached to the back side of the weed board.

〔Example〕

Hereinafter, a grassroots pruning machine according to the present invention will be specifically described with reference to the drawings. This grassroots plucker is X
A pair of operating rods 1 and 1 which are pivotally supported so that they can be opened and closed in a circular pattern, are provided with opposing weed plates 2 and 2 at their lower ends, and a plurality of curved plates are provided at the lower part of each weed plate 2 in the opposite direction. The comb tooth pieces 3 are formed in a staggered shape, and a sharp and solid blade portion 4 is formed at the tip end portion of each comb tooth piece 3, and the other operating rod 1 is provided at the bottom of each operating rod 1. A protrusion piece 5 extending to the back side of the weed plate 2 attached to the lower end of the weed plate 2 is provided, and a support piece 7 having a cleaning piece 6 having substantially the same width as the weed plate 2 is provided at the tip of the projecting piece 5 as a pivot pin 11. The cleaning piece 6 is brought into contact with the rear surface side of the weeding board 2 by a spring 8, specifically, a torsion coil spring, which is pivotally supported on the protruding piece 5 and the support piece 7. The protrusions 5,5 provided at the bottom of the operating rods 1,1 are
The intersecting bases are pivotally supported by a central pin 9, and the central pin 9 serves as a pivotal point when the operating rods 1, 1 are opened and closed. Spherical grips 10, 10 at the upper end of each operating rod 1, 1.
Have. From the viewpoint of operability, it is desirable that the number of comb teeth 3 formed on the lower part of the weeding plate 2 is about 5 pairs. The torsion coil spring used as the spring 8 is inserted into and held by the pivot pin 11, and one end is locked to the projecting piece 5 and the other end is locked to the supporting piece 7 so that the cleaning piece 7 is full width on the back surface of the weed plate 2. Are abutted over. The cleaning piece 6 is in contact with the tip end of the weeding plate 2, that is, the back side of the comb tooth piece 3 when the spacing between the weeding plates 2 is maximal. As the distance between 2 and 2 narrows, it moves upward while contacting the back surface of the grass plate 2, and when the two grass plates 2 and 2 are in contact with each other and the comb tooth pieces 3 and 3 cross each other in a staggered manner. The cleaning piece 6 contacts the upper end of the rear surface of the weeding board 2, and when the spacing between the two weeding boards 2, 2 is opened again, the cleaning piece 6 slides toward the tip of the weeding board 2. Reference numeral 12 in the drawing denotes a stopper piece, which is provided on one operating rod 1 slightly above the projecting piece 5 and below the crossing point with the other operating rod 1 so that the weed plate 2, When the two are opened at excessive intervals,
This stopper piece 12 is locked to the other operating rod 1 to operate 1.
It prevents over-opening of 1 and the weeds 2,2.

The grass root pruning machine according to the present invention is constructed as described above. When using the grass pruning machine, first, the user holds the grips 10 of the operating rods 1 in the left and right hands while standing. Open the space between the grass plates 2 and 2, and insert the weeds between the grass plates 2 and 2 so that the weeds are stabbed into the soil at the root. At that time, the blade-shaped portion 4 formed on each comb tooth piece 3 at the tip of the grass plate 2 cuts a root widely spread in the soil around the root, and leaves only the main root in the weed. . Next, the two grips 10 and 10 are strongly attracted to each other and the weeds are held by the weed plates 2 and 2. At this time, the comb tooth pieces 3, 3 of the two cutting boards 2, 2 intersect at the blade-shaped portion 4 in a staggered manner while cutting the root, and the cleaning piece 6 is on the upper back side of the cutting board 2. Are moving. Then, the device of the present invention is lifted up as it is, and the weeds held by the weed plates 2, 2 are pulled out. This withdrawal operation can be easily performed because most of the weed roots have already been cut in the previous work step. Also, the comb tooth pieces 3,2 of the two grass plates 2,2
Since they cross each other in a staggered pattern, there is no risk of weeds deviating during the extraction operation. Finally, after the weeds have been pulled out, the two gripping parts 10, 10 are separated from each other, and the weeds boards 2, 2 that previously held the weeds are opened and the weeds are discarded. At that time, the grass board 2
As the tip of the projecting piece 5 tilts downward with the central pin 9 as the claws open, the projecting piece 5 is pivotally supported by the supporting piece 7 and the rear surface of the weeding board 2. The cleaning piece 6, which is brought into contact with the lower part of the lower part, slides downward on the back surface of the weeding board 2 to scrape off the mud and weeds attached to the back surface of the weeding board 2. Therefore, even if the above-mentioned steps of weeding work are continuously repeated, mud and weeds do not adhere to the weed board.

〔The invention's effect〕

Since the grass root pruning machine according to the present invention is designed to hold and pull out weeds by a weeding plate fixed to the lower ends of a pair of operating rods that can be opened and closed as described above, it is unnatural to bend down as in the past. You can do weeding work in a comfortable posture while standing up, without having to take a different posture.

In addition, at that time, since the comb tooth pieces provided at the lower part of the weeding plate intersect in a staggered manner, the weeds do not deviate downward between the weeding plates and do not fail to be pulled out, and it is possible to reliably pull out the weeds. I can. Furthermore, since the blade-like part is formed at the tip of each comb tooth piece, even for weeds that have roots that are difficult to pull out, most of the roots are cut by the blade-like part in the process of holding the root of this weed. Easy to pull out. Therefore, it is not necessary to perform the complicated work of backfilling the hole created by forcibly attracting the rooted weed as in the past. In addition, when the weeds are opened and the weeds removed are discarded, the cleaning piece slides downward from the upper back of the weeds as the weeds open. It can also remove mud and weeds attached to the back of the grass plate. Therefore, when weeding work is performed using the device of the present invention, there is no fear that it becomes heavy and difficult to handle due to adhesion of mud and weeds, and the time and effort required to remove the weeds and mud by hand are unnecessary. Compared with the method described in 1), the work efficiency is significantly improved.
