Description

  The present invention relates to a weeding tool used for removing weeds and the like.

  Weeding tools of various structures are known as hand tools, but the weeding tool according to the present invention has a U-shape in which both ends of a weeding blade body, especially called weeding, are connected to the handle portion. It is an instrument that employs a blade.

  Specifically, both sides of the U-shaped blade body are connected to a handle mounting body having a bifurcated mounting arm, and an instrument (Patent Document 1) in which the handle mounting body is mounted on an appropriate long handle, An instrument (Patent Document 2) is known in which both side portions of a U-shaped blade body are directly screwed to the side surface of a handle body.

Japanese Patent Laid-Open No. 9-121601. JP 2007-215411 A.

  In an instrument having a structure in which both ends of the weeding blade body are connected to the handle portion, simplification of the blade body mounting structure and provision of multi-function are achieved.

  The weeding tool according to the present invention has a rectangular blade body with a bifurcated blade body mounting part at the tip of the handle part, a cutting blade on one edge and a rake tooth on the other edge, with the handle part raised. The blade body is installed between the blade body mounting portions so that the blade body is substantially horizontal and the cutting blade is located on the handle side.

  Thus, when the rectangular blade is held in a horizontal state (parallel to the ground) and the tool is pulled toward the weeds on the near side of the rectangular blade, weeding is performed in the same way as in the conventional grass cutting operation. When the weeding operation is completed, when the handle portion is turned upside down and held, the rectangular blade body is in an upright state, the rake teeth are positioned below, and the cut weeds are raked (rake operation) be able to.

The invention according to claim 2 is formed by forming the cutting blade into a triangular wave blade by serration processing, and can easily form a blade with excellent cutting efficiency.

Further, the invention of claim 3 is provided with a shaft portion projecting at the center of both end edges of the rectangular blade body, and forming a metal plate in a curved shape on the facing surface of the blade body mounting portion as the facing surface. The insertion hole is formed and a non-rotating protrusion of the rectangular blade body is formed around the insertion hole. The rectangular blade body can be attached to the blade attachment portion with simple manufacturing means.

Further, the invention according to claim 4 is that the rectangular blade body is formed so as to be capable of rotating by a small angle, particularly when the anti-rotation projection is formed, and this rotation is so-called play, mowing work and rake work. In this case, it has a function of absorbing the change with respect to the unevenness of the ground surface.

  The present invention has the above-described configuration and can perform mowing (grass cutting) work and scraping work with a single instrument.

1 is an overall perspective view of an embodiment of the present invention. The principal part expansion perspective view. It is explanatory drawing (side view) of a use state, (a) shows the time of mowing (b) shows the time of scraping. The same figure (perspective view).

  Next, an embodiment of the present invention will be described. The weeding tool shown in the embodiment includes a rectangular blade body 1, a blade body mounting body 2, and a handle portion 3.

  The rectangular blade body 1 is a rectangular plate having a width of about 3 to 4 cm and a length of about 8 to 12 cm. A cutting blade 11 formed on a triangular wave blade by serration processing is formed on one edge in the length direction, and the other edge is formed of a triangular tooth. The rake teeth 12 are formed. Further, a shaft portion 13 is provided by winding a protruding portion around the center of the short edge, and an appropriate through hole 14 is provided in order to reduce the weight.

  The blade mounting body 2 is connected to the handle portion 3 with a vertical plate portion of a T-shaped metal plate (stainless steel plate) as a base 21, and the horizontal plate portion is bent obliquely downward to be an arm plate portion (blade mounting). Part) 22. An insertion hole 23 of the shaft portion 13 is formed at the distal end portion of the arm plate portion 22, and an anti-rotation projecting portion 24 of the rectangular blade body 1 is formed around the insertion hole 23 so that the rectangular blade body 1 is armed. It is constructed by mounting between the plate portions 22 at a fixed angle.

  In particular, the anti-rotation protrusion 24 is provided so that the rectangular blade body 1 is not fixed at a constant angle but can be rotated by a minute angle (10 to 15 degrees).

  The handle portion 3 is made of resin and is integrated with the base portion 21 by an appropriate means.

  In particular, the mounting angle of the rectangular blade body 1 with respect to the arm plate portion (blade body mounting portion) 22, that is, the formation position of the anti-rotation protrusion 24, as shown in FIG. 1 is substantially horizontal, and the cutting blade 11 is positioned on the handle portion 3 side. Specifically, the center angle between the horizontal surface of the rectangular blade 1 and the handle portion 3 is 45 degrees or less (for example, the angle a is 40 degrees).

  Thus, the instrument holds the grip portion 3 with the rectangular blade body 1 in a substantially horizontal state (a state parallel to the ground), and when the instrument is pulled toward the weed A on the near side of the rectangular blade body 1, Weeding can be done in the same way as mowing. When the handle 3 is held at an inclination of 30 degrees (angle b) with respect to the ground surface during this weeding operation, the rectangular blade 1 is cut into the weed A at an angle of 10 degrees with respect to the ground surface. The grip portion 3 can be held at an angle at which it is easy to pull with a strong force to perform the mowing (mowing) operation.

  Further, when the weeding operation is completed, when the handle portion 3 is held upside down, the rake teeth are positioned downward, and if the holding angle c of the handle portion is set to 50 degrees, the rectangular blade 1 is vertically When the erected state is maintained and the angle is further reduced, the rectangular blade body 1 is in an inclined state where the upper side is the front side, and the weed B is scraped by holding the handle portion 3 at an angle at which it is easily pulled (rake) Work).
