Description

  The present invention relates to the technical field of weeding equipment, and more particularly to a rake-type weeding equipment.

  Conventionally, various rake-type weeding tools in which a rake-shaped scraping portion is provided at the tip of the gripping portion are known (see Patent Documents 1 to 5).

JP 2004-8099 A JP 2005-261220 A JP 2009-39090 A Utility Model Registration No. 3122145 Japanese Utility Model Publication No. 5-39231

  However, in these conventional rake-type weeding tools, the claws of the rake-shaped scraping part are all integrated and cannot be partially replaced. It is also possible to change the configuration of the scraping unit according to the type and soil quality of the grass to be weeded and the physical strength of the user side (for example, elderly people have a significant decrease in physical strength compared to others). It was practically difficult. Further, even if it is attempted to repair in the event of a failure or the like, it is difficult to repair using easy-to-obtain parts that are commercially available, for example, at home centers, etc., since all are made up of dedicated parts.

  Then, this invention makes it the subject to provide the rake type weeding instrument which solved these problems.

In order to solve the above problems, the present invention is a rake-type weeding device provided with a rake-type scraping portion at the tip of a gripping portion, wherein the scraping portion is formed by bending a wire of substantially the same length into a crank shape. The plurality of claw members are arranged in parallel and fixed with staples on the bottom surface of the gripper so that one end protrudes from the tip of the gripper, and the other end of the claw member is It is characterized by being driven into the bottom of the gripping part and fixed.

In this way, by adopting a configuration in which the scraping portion is configured with a plurality of crank-shaped claw members and fixed with staples, even if some claw members break or wear progresses, a specific claw It is possible to replace only the member.

Furthermore, since it is possible to easily change the number and thickness of the claw members, it is easy to change to a configuration that is easy to use according to the type and soil quality of the grass to be weeded and the physical strength of the user. For example, in the case of hard soil, it is easy to insert the scraping portion into the soil by reducing the number of claw members, so that it becomes an easy-to-use weeding tool for those who do not have physical strength such as elderly people.

  In addition, the claw member that needs to be repaired is formed by bending the wire, and fixing the wire to the gripping part can be performed by, for example, using a staple for electric wires. Even when it is necessary, it is possible to easily obtain the parts at a home center and repair or modify them.

  Further, since the claw member is formed in a crank shape and the other end side is driven into the bottom surface of the gripping portion, the claw member does not fall off in the front end direction during use.

  By applying the present invention, it is possible to replace only some of the nails constituting the scraping unit and easily change the configuration of the rake-type scraping unit according to the use and the physical strength of the user. In addition, since it is made of an easily available material, it can be easily repaired or modified.

It is a side view of the rake type weeding implement concerning the present invention. It is a bottom view of the rake type weeding implement concerning the present invention. It is the figure which showed the usage example of the rake type weeding instrument based on this invention.

  Hereinafter, with reference to the attached drawings, a rake type weeding instrument 100 as an example of an embodiment of the present invention will be described. For easy understanding of the drawings, it should be noted that there are portions where the size and dimensions of each portion are exaggerated and there are portions that do not necessarily match the actual product. In addition, each drawing is viewed in the direction of the reference sign, and is expressed as upper, lower, left, right, near, and back based on the direction.

<Configuration of rake type weeding device>
As shown in FIGS. 1 and 2, the rake-type weeding device 100 according to the present invention includes a grip portion 102 that is gripped by a hand during use and a scraping portion 101 provided at the tip of the grip portion 102.

  In the present embodiment, the grip portion 102 is cut into an appropriate size that makes it easy to grip the wood, and rounding processing of corner portions is performed so that the grip portion 102 is easy to grip.

In the present embodiment, the scraping portion 101 is configured such that five claws have a rake shape, and as shown in FIG. 2, a wire having substantially the same length is bent into a crank shape. The five claw members 104 configured as described above are arranged in parallel.

  The five claw members 104 arranged in parallel are fixed at a position where the scratching claw 104 a on one end side protrudes from the tip of the grip portion 102. Further, the tip of the claw member 104 (scratching claw 104a) is bent so as to have an angle θ of about 80 degrees (see FIG. 2), and it is intended to bite in the ground direction by applying a pulling force toward the front side. It is comprised so that the force to do may generate | occur | produce. The claw member 104 is fixed by two staples 106. As the staple 106, for example, a staple for fixing an electric wire is used.

  The other end side of the claw member 104 is driven and fixed to the bottom surface of the grip portion 102. Thereby, it can prevent that the scratching nail | claw 104a of the nail | claw member 104 moves to the width direction (W direction in FIG. 2), and it is set as the structure which a nail | claw member does not fall out to a front end direction at the time of use.

  In the present embodiment, the wire constituting the claw member 104 is made of iron and has a diameter of 2 mm. Since the protruding length L is about 28 mm and the height (depth) of the scratching claw 104a is about 18 mm, a sufficient strength can be ensured even if the meridian is 2 mm.

<Action and function of rake type weeding device>
When using the rake-type weeding device 100 according to the present invention, the grasping portion 102 is grasped by hand, and the scratching claw 104a is scratched by the plant portion (root portion) of the plant 10 to be weeded and pulled forward. (See FIG. 3). In the case of a plant having a large plant part, weeding is repeated by repeating the operation of dividing and scratching part by part.

Some or all of the claw members 104 may break or wear due to repeated use. As described above, the scraping portion 101 is composed of a plurality of crank-shaped claw members 104 and fixed with staples 106. By adopting such a configuration, even when some of the claw members 104 break or wear progresses, it is possible to replace only a specific claw member 104.

Further, since the number and thickness of the claw members 104 can be easily changed, it is easy to change the configuration to be easy to use according to the type and soil quality of the grass to be weeded and the physical strength of the user. ing. For example, in the case of hard soil, it is easy to insert the scraping portion 101 into the soil by reducing the number of the claw members 104, so that it becomes an easy-to-use weeding instrument for those who do not have physical strength such as elderly people.

  Further, the claw member 104 that requires repair is formed by bending a wire and is fixed to the grip portion 102, so that even when the claw member 104 needs to be repaired due to breakage or wear, The parts can be easily obtained at home centers and repaired or modified by yourself.

<Other configuration examples>
In the above description, the rake-shaped scraping portion 101 is configured by the five claw members 104, but the number is not limited to five. It can be changed as appropriate according to the type and soil quality of the plant to be weeded and the physical strength of the user. The material is not limited to iron, and a wire made of other materials such as a stainless steel wire (steel wire) may be used.
