Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grassroots plucking machine that pulls out strongly rooted weeds, including their main roots, growing in the gardens, parks, fields, and fields of households.

[Conventional technology]

A sickle is used as an agricultural tool to cut down weeds, but even after cutting with a sickle, the roots still remain, so the weeds will grow back after the cutting, making it impossible to completely eradicate the weeds. Therefore, as a means of eradicating weeds, it is common practice to manually pull out the weeds along with their roots.

[Problem to be solved by the invention]

However, the work of plucking individual weeds one by one while bending over for long periods of time in an unnatural posture is extremely arduous and the work efficiency is extremely low. For example, weeds with widely spread roots are difficult to pull out. If you forcefully pull it out, the soil around the roots will also be removed, leaving a large hole, which is a hassle as you will have to backfill each hole one by one.

Therefore, the present invention has been made based on the above circumstances, and allows weeding work to be carried out in a comfortable posture.Moreover, by simple operation, weeds can be efficiently removed from the main roots one after another. The purpose of the present invention is to provide a grassroots plucking machine that can pull out both roots.

[Means to solve the problem]

To achieve the above-mentioned object, the grass weeding machine according to the present invention has a pair of operating rods arranged in a central bin at the lower part thereof.
A plurality of comb tooth pieces curved in opposite directions are provided at the bottom of both the comb plates in a staggered manner. A blade-shaped portion is formed at the tip of the piece, and each operating rod is provided with a protruding piece that extends to the back side of the isolating plate attached to the other operating lever, and the tip of the protruding piece is provided with a protruding piece having approximately the same width as the isolating plate. The proximal end of a support piece having a cleaning piece is pivotally supported, and the cleaning piece is brought into contact with the back side of the weeding plate by means of a spring. It is characterized in that the pieces slide up and down on the back side of the grass board.

[For production]

In the grass root remover according to the present invention, by closing the upper parts of the pair of operating rods, the weed plates provided at the lower ends of both operating rods clamp weeds, and the weeds (teeth pieces) at the bottom of both operation rods are edible. They intersect in a diagonal pattern to prevent downward deviation when pulling out weeds.

In addition, at this time, the blades of each of the weed boards cut into the roots of the weeds and the widely spread roots are cut in the middle. When discarding weeds that have been pulled out while being held by a weed board, as the distance between the weed boards increases, the cleaning pieces slide from the top to the bottom of the back of the weed board and adhere to the back side of the weed board. Remove weeds and dirt.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a grass root remover according to the present invention will be specifically described with reference to the drawings. This grassroots plucking machine is provided with grass plates 2.2 facing each other at the lower ends of a pair of operating rods 1, 1 which intersect in an X shape and are pivotally supported so as to be openable and closable. A plurality of comb tooth pieces 3 curved in opposite directions are formed in a staggered manner, and a sharp and strong blade-like portion 4 is formed at the tip of each comb tooth piece 3. A support having a protrusion 5 at the lower part extending to the back side of the washer plate 2 attached to the lower end of the other operating lever 1, and a cleaning piece 6 having approximately the same width as the washer plate 2 at the tip of the protrusion 5. The piece 7 is pivotally supported by a pivot pin 11, and the cleaning piece 6 is brought into contact with the back side of the weeding plate 2 by a spring 8, specifically a torsion coil spring, spanning the projecting piece 5 and the support piece 7. It is. The protrusions 5, 5 provided at the bottom of the operating rods 1, 1 have their intersecting bases rotatably supported by a central pin 9, and this central pin 9 controls the opening and closing of the operating rods 1, 1. It serves as a pivot point. Each operating rod 1,1 has a spherical grip portion 10.10 at its upper end. From the viewpoint of operability, it is desirable that the number of comb tooth pieces 3 formed at the lower part of the comb plate 2 is about three pairs. Further, a torsion coil spring used as the spring 8 is inserted through a pivot pin 11 and held, and one end is locked to the protruding piece 5 and the other end is locked to the support piece 7, so that the cleaning piece 7 is attached to the back side of the washer plate 2 over the entire width. It is in contact across the entire length. When the distance between the comb plates 2 and 2 is the maximum, the cleaning piece 6 is in contact with the tip of the comb plate 2, that is, the back side of the comb tooth piece 3, and As the distance between the combs 2 and 2 narrows, it moves upward while coming into contact with the back surface of the comb plate 2, and in the state where both the comb plates 2 and 2 are in contact and the comb tooth pieces 3 and 3 intersect in a staggered manner. , which comes into contact with the upper end of the back surface of the grass board 2, and when the space between the grass boards 2, 2 is opened again, the cleaning piece 6 slides toward the tip of the grass board 2. In addition, the code 12 in the figure is strike yi
<- piece, on one operating rod 1 slightly above the protruding piece 5,
The stopper piece 12 protrudes downward from the point where it intersects with the other operating lever 1, and when the clamping plates 2, 2 are opened at an appropriate distance, this stopper piece 12 locks onto the other operating lever 1 and is operated. 1, 1 and the support plates 2, 2 are prevented from opening too much.

The grassroots tearing machine according to the present invention is constructed as described above, and when using it, the user first holds the grip part 10 of 1° of each operation lever in the left and right hands while standing. The space between the weed plates 2 and 2 is widened, and the weeds are sandwiched between the weed plates 2 and 2 and pushed into the soil at the base of the weeds. At that time, each tip of the cutting board 2 (the blade-like part 4 formed on the toothed piece 3)
Cut the widely spread roots in the soil around the base, leaving only the main roots on the weed. Next, both gripping parts 10.10
The weeds are forcefully pulled with the weed plates 2, 2.At this time, the toothed pieces 3, 3 of both the weed plates 2, 2 cut the roots and cut the weeds in a staggered manner. , and the cleaning piece 6 has moved to the upper part of the back side of the weed plate 2.Then, the device of the present invention is lifted upwards and the weeds held between the weed plates 2, 2 are pulled out. The operation is easy because most of the weed roots have already been cut in the previous work process.Also, the comb tooth pieces 3 and 3 of both comb plates 2゜2 intersect in a staggered manner. Therefore, there is no fear that the weeds will deviate during the pulling operation.

Finally, after pulling out the weeds, the two gripping parts 10.10 are separated from each other, the weeding plate 2.2 that was holding the weeds is opened, and the weeds are thrown away. At this time, as the grass plate 2 opens, the tip of the protruding piece 5 tilts downward about the central bin 9, so that it is pivoted to the protruding piece 5 via the support piece 7. A cleaning piece 6 is brought into contact with the back side of the grass board 2 from below.
, slides the back surface of the grass board 2 downward to scrape off mud and weeds attached to the back surface of the grass board 2. Therefore, even if each step of the above-mentioned weeding work is repeated, mud and weeds will not adhere to the weeding board or the like.

〔Effect of the invention〕

As described above, the grass root weeding machine according to the present invention is capable of holding and pulling out weeds by using a weed plate fixed to the lower end of a pair of operating rods that can be opened and closed. You can do the weeding work in a comfortable standing position without having to take a difficult position.

In addition, since the comb teeth provided at the bottom of the weed plates intersect in a staggered manner, the weeds do not deviate downward from between the weed plates and fail to be pulled out, and the weeds can be pulled out reliably. I can do it. Furthermore, since a blade-shaped part is formed at the tip of each tooth piece, most of the roots of weeds that are hard to pull out due to their roots can be cut off by the blade-shaped part in the process of holding the base of the weed. Can be easily pulled out. Therefore, there is no need to perform the complicated work of filling in holes caused by forcibly pulling out rooted weeds as before. In addition, when opening the weed plate and discarding the weeds that have been pulled out, the weed plate is opened so that the cleaning piece slides downward from the top of the back of the weed plate. Mud and weeds attached to the back side of the grass board can also be removed.

Therefore, if weeding work is carried out using the device of the present invention, there is no risk of it becoming difficult to handle due to mud and weeds adhering to it (indeed, it becomes heavy), and there is no need to remove the weeds and mud by hand. Compared to the bare-handed method, work efficiency is greatly improved.
