Description

  The present invention relates to a weeding tool that can easily remove weeds growing in a garden, vegetable garden, or road surface.

  Reap the weeds that grow in the garden, vegetable garden or road surface. Various weeding tools have been proposed for extracting from the roots. For example, in Patent Document 1, a long scoop is provided with a scooping portion having a scoop and a mulberry shape on the other end, and weeds dug up with the scoop are sandwiched and extracted by the mulberry shape portion. Since this one digs up and grabs the root of each weed, it takes time, and the handle at the rear end of the handle is operated with the gripping force of one hand, so there is a problem that the hand is tired and does not last long It was. The thing of patent documents 2 is almost equivalent to the thing of patent documents 1 about the pinching part of weeds, one is a shovel and the other is a jagged gripping blade. However, since this is a fire scissors shape, it is operated with one hand grip force, so there is a problem that the hand is tired and does not last long.

Moreover, the thing of patent document 3 presses a movable blade against the fixed blade provided in the front-end | tip of a long handle, and is made to pinch weeds. This is one in which a lever provided at the rear end of a long handle is operated with one hand to rotate the movable blade, and since it is also operated with one hand gripping force, there is a problem that the hand is tired and does not last long.

  The present invention removes the grass more efficiently by sandwiching the root from a very small grass to a firmly rooted grass without touching the soil or grass directly without getting tired by natural operation without overdoing while standing. It is to provide a weeding tool that can.

  In the weeding tool of the present invention, a handle 4 for pulling two rods 3 is provided perpendicularly to the long handle 1 at a handle mounting portion 2 provided on the rear end side of the long handle 1. The U-shaped rocking plate 5 connected to the rod 3 is swung by the pulling operation 4, and the surface of the contact plate 5 b, which is a connecting portion of both the arms 5 a of the rocking plate 5, is abutted against the cutting edge of the scissors blade 6. It is characterized by cutting or weeding weeds by drawing 1.

  Further, as described in claim 2, a U-shaped shaft support plate 7 is provided on the base portion 6a of the scissors blade 6 so as to face downward, the base portion 6a of the scissors blade 6 is fitted into the tip of the long handle 1, and the shaft support plate 7 The two rods 3 connected to the handle 4 at the ends of both arms 5a are supported by shaft support pins 8 on the lower 1/3 of both arms 5a of the swing plate 5 to the U-shaped arms 7a. When the handle 4 is pulled, the two rods 3 connected to the handle 4 pull in the ends of both arms 5a of the swing plate 5, and the other end side of the contact plate 5b around the pivot pin 8 And the surface of the abutting plate 5b is abutted against the blade edge of the scissors blade 6.

  Further, as described in claim 3, the bending angle α of the handle mounting portion 2 of the long handle 1 is set to about 20 degrees, and the bending angle β between the base end 6 a fitted to the distal end of the long handle 1 and the blade surface of the scissors blade 6. Is about 75 degrees, and the handle 4 is pulled to set the angle γ between the blade edge of the scissors blade 6 and the surface of the contact plate 5b of the swing plate 5 to be about 55 to 60 degrees.

  The weeding tool of the present invention has a handle with one hand in a standing posture, and holds the handle with the other hand and moves it back and forth so that weeding is continuous compared to the conventional one-hand operation type using the grip strength. You will not get tired even if weeding. In addition, by sandwiching the root of the grass with one of the blades and the other as a backing plate, it is possible to easily extract from a very small grass to a firmly rooted grass. In addition, since it can be processed with the grass in between, it is not necessary to touch the soil or grass directly with your hands.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In the weeding tool of the present invention, a handle for pulling a rod is attached to a handle attachment portion provided about 1/3 of the rear end side of the long handle, and a U-shaped swinging piece connected to the rod is swung by pulling the handle. Then, the surface of the contact plate, which is the connecting portion of both arms of the swinging piece, is abutted against the scissors blade and the long handle 1 is pulled forward to cut or weed the weeds.

  That is, as shown in FIG. 1, the weeding tool of the present invention has a handle 4 for pulling two rods 3 on a handle mounting portion 2 provided about 1/3 of the rear end side of the long handle 1 so as to be orthogonal to the long handle 1. The U-shaped swinging plate 5 connected to the rod 3 is swung by pulling the handle 4, and the surface of the abutting plate 5b, which is the connecting portion (bottom surface) of both the arms 5a of the swinging plate 5, is used as a scissors blade. The weeds are cut or extracted by pulling the long handle 1 against the 6 blade edges. The rod is a wire # 12 or so.

  More specifically, the center portion of the U-shaped shaft support plate 7 is fixed to the base portion 6 a of the scissors blade 6 by welding, and the base portion 6 a of the scissors blade 6 is fitted into the tip of the long handle 1. The U-shaped arms 7a of the pivot support plate 7 are each pivotally supported by a pivot pin 8 at the lower one third of both arms 5a of the swing plate 5, and are connected to the handle 4 at the ends of both arms 5a. The two rods 3 are connected to each other. When the handle 4 is pulled, the two rods 3 that are connected to the handle 4 pull in the ends of the arms 5a of the swing plate 5, and the connecting portion that is in contact with the other end, that is, the contact plate 5b, is rotated around the pivot pin 8. The surface of the abutting plate 5b is abutted against the blade edge of the scissors blade 6. In order to operate the two rods 3 stably, they are fixed with iron wires 9 so as to be moved inward in the middle of their lengths.

  Further, the handle mounting portion 2 of the long handle 1 is in a bent position, and the bending angle α is about 20 degrees. The bending angle between the base end 6 a fitted into the tip of the long handle 1 and the blade surface of the scissors blade 6. β is approximately 75 degrees, and the angle γ formed by pulling the handle 4 and the cutting edge of the scissors blade 6 and the surface of the contact plate 5b of the swing plate 5 is set to be approximately 55 to 60 degrees.

  In this weeding tool, the position of the pivot pin 8 of the swing plate 5 is set to a ratio of 2 to 1 in terms of the arm length ratio, the length from the scissors blade 6 to the handle mounting portion 2 of the long handle 1 is 70 cm, and the handle is mounted. The operability and ease of handling are improved by setting the length from the portion 2 to the rear end of the long handle 1 to 50 cm. Further, since the long handle 1 is bent, the hand holding the handle 4 and the hand holding the rear end of the long handle 1 are well balanced and easy to hold. In addition, since the two right and left rods 3 transmit force equally to both arms 5a of the swing plate 5, the contact plate 5b is reliably pressed against the scissors blade 6 so that the roots of the weeds can be sandwiched.

  When removing weeds using the weeding tool of the present invention, hold the handle 4 with one hand, hold the rear end of the long handle 1 with the other hand, pull the handle 8, and attach the backing plate 5b to the scissors blade 6. Pull the entire long handle 1 with the roots of the weeds in contact with the cutting edge to remove the weeds. In the normal case, the center or the entire width of the scissors blade 6 is used, and when small weeds are extracted one by one, the end of the scissors blade 6 is used for easy operation.

It is a perspective view in the state where the handle of the weeding tool concerning the present invention is not pulled. It is a perspective view of the state where a handle was pulled. FIG. 3 is a front view of FIG. 2. FIG. 3 is a plan view of FIG. 2. FIG. 3 is a side view of FIG. 2.
