Description

      In this invention, when weeding a field or a garden, a conventional weeding sickle only digs up the root of the grass, it is necessary to collect the grass by hand, the recovery is cumbersome, the soil with sand attached to the root There was a flaw to get dirty. This plan is devised to solve the problem, and it is related to a weeding tool that digs up the root of the grass with a root cutting blade, collects grass and earth and sand in a collection box, and sifts out the earth and sand that has arrived at the root of the grass with a net part. is there.

      The conventional “weeding sickle” shown in the following document only digs up the root of the grass, and the grass must be collected by hand. In another invention, the root cutting blade and the recovery blade are configured in two pieces, the root is cut up by the root cutting blade, and the grass is collected by the recovery blade. Depending on the size of the grass, the root cutting blade and the recovery blade It was difficult to adjust the gap between the blades, the cost was high, and the usability was poor. This plan is a solution to these problems.

JP-A-10-000009 Japanese Patent No. 5115896

    The present invention has been made in view of the above circumstances, digging up the roots of the grass with a root cutting blade and dropping it into the collection box at the same time, shaking the earth and sand adhering to the root with a net-like part provided on the bottom of the collection box, and bucketing the grass A series of operations such as throwing it away can be processed with a single “weeding tool”.

(1) Devising a structure for digging up grass roots and collecting grass at the same time.
(2) Devising a structure that can easily drop the collected grass and sand.
(3) Devising a structure that allows the collected grass to be easily discarded in a bucket or the like.

(1) The root cutting blade and the collection box are connected continuously, the handle is held horizontally, and when pulled, the grass roots are dug up and the grass is fed into the collection box at the same time.
(2) The bottom of the collection box is a mesh, and the earth and sand are screened off by the operation of placing the tip of the collection box against the ground.
(3) The handle was rotated, the collection box was turned over, and the grass was easily discarded in a bucket or the like.

By the above solution, the following points are greatly improved as compared with the conventional product.
(1) The grass was dug up and the grass was collected at the same time, eliminating the need for manual grass collection.
(2) The collected grass roots and sand can be screened by applying a vibration to the ground with the bottom of the collection box as a mesh.
(3) The collection box was turned upside down by turning the handle, and it was easily thrown away into a bucket, so that grass could be collected without using hands.

Hereinafter, the structure and use operation of the present plan will be described with reference to FIGS.
1 in FIG. 1 is an overall perspective view of the present plan. A 4 collection box is joined to the outside of the 2b stay rising from the side surface in the width direction of the 2a root cutting blade by 4a point welding, and a 2c handle is held on the upper surface of the extended stay. The member is spot welded or 2d-joined, the 3 handle is joined to the 2c handle holding member, and as shown in FIG. 2, the top surface of the 2a root cutting blade and the center line of the 3 handle are set at an angle θ1 of about 45 degrees. Yes.
In addition, the 4 recovery box is covered with a metal plate on the outer peripheral surface, and the bottom surface is joined with 5 mesh members. The top surface of the 5 mesh member and the top surface of the 2a root cutting blade are set continuously at an angle θ2 = about 145 degrees. Yes.
The material of the 2a root cutting blade is preferably stainless steel or hardened steel.
Fig. 2 is an explanatory diagram of the weeding operation. When the 3 handles are pulled horizontally, the 2a root cutting blade bites into the ground, the grass roots and earth and sand are both fed to the top of the 2a root cutting blade, and pushed out into the 4 collection box. Sediment falls from the bottom net to the ground. 3 is a cross-sectional view taken along the line AA ′ of FIG.
Arrangement of 2a root cutting blade, 4a spot welding of 4 collection box, 2d handle holding member 2d crimping rod and the like is shown. FIG. 4 is an explanatory diagram of the operation of dropping grass and sand. When the handle is tilted upward and the tip of the 4 collection box is struck against the ground, the earth and sand easily fall from the mesh by vibration shock.
In addition, it is important to determine the mesh size of the mesh. According to the inventor's experimental results, small weeds that normally grow in fields, etc., apart from extremely fine grass, will not leak if they are 5 mm square. On the other hand, earth and sand will pass even if it is a very large stone or a lump of soil if it is 10 mm square. Therefore, there is no practical problem if it is about 7mm square in an ordinary field. It is preferable to determine the size of the grass and the state of the earth and sand. The mesh material is preferably a stainless wire mesh in terms of strength and rust. The mesh is preferably spot-welded using an auxiliary plate.
Next, when the 4 collection boxes are full of grass, rotate the 3 handles 180 degrees so that the 4 collection boxes lie on a bucket etc. as shown in “Weeding operation” in FIG. When the handle holding member is tapped lightly on the upper surface of a bucket or the like, the grass entangled with the five mesh members also falls cleanly.

From the above description of the structure, the description shifts to the description of the operating method. As an explanation of the operation, please refer to FIGS.
Fig. 2 shows the weeding operation. If you grab three handles and pull them while applying a slight downward force, the 2a root cutting blade can cut into the ground and cut the grass roots. Therefore, the deeply rooted object needs to increase the downward force. When 3 patterns are drawn, 2a root cutting blade advances in the pulled direction, grass and earth and sand rise up the slope of 2a root cutting edge and are pushed out onto 5 mesh members of 4 collection boxes, and earth and sand are extracted from the mesh of the mesh. Spill down and fall to the ground.
4. If grass increases in the collection box, it will be difficult for the earth and sand to fall. Therefore, as the grass removal operation shown in FIG. At the same time, earth and sand easily fall.
Next, when the 4 collection box is full of grass, as shown in Fig. 5, if you prepare a bucket etc. and rotate the 3 handles 180 degrees, the 4 collection box will be turned over and the grass will fall into the bucket. .
However, when the roots of the grass cannot be removed by entanglement with the mesh of the net, the grass is easily removed by vibration and falls when the 2c handle holding member is struck against the upper surface of the bucket.
If the collection box is small, the length of the three handles is usually about 300 mm. However, to make the collection box larger and take a lot of grass in a standing position, it is about 1000 mm, and θ1 is about 60 degrees. It is preferable to make it.

Garden and field weeds germinate quickly when there is a lot of rain.
It is troublesome to feel that comes, but other than that, do not take from the grass roots,
If you cut only the leaves on the top, it will grow particularly fast.
For countermeasures against such a cause, use the “Weeding Tool” of this proposal and root the grass.
Would you like to be able to pull up and collect grass without using your hands just by pulling the handle?
If mass-produced, it can be produced cost-effectively and without a heavy burden.
We are proud that the invention will be appreciated by producers.
