Description

  The present invention relates to a weeding tool used when weeding fields. In particular, it is suitable for weeding such as straw with a relatively soft soil surface.

  As the weeding tools used when weeding fields, weeding tools called hand canna are generally used. There are many other shapes, such as triangular cocoons and weeping mushrooms.

  Efficient weeding is carried out diligently immediately after germination of weeds, and when the grass sprouts, it is quickly weeded. Necessary requirements for weeding dredging etc. at this time are to be able to do it easily and to reduce soil movement accompanying weeding in order to minimize the adverse effects on the sown crops.

  It is desirable that weeding work can be done with as little force as possible.

  In order to make weeding work more efficient, weeding tools must be of a size suitable for the work space. Another problem is that it can be procured at low cost.

  It is desirable that the weeding tool can cope with working while standing or squatting.

  The weeding tool is provided with a weeding blade at the tip of the handle, and the weeding blade has a structure in which a wire is stretched over a wire support.

  The wire support is an elastic body.

  One or a plurality of weed cutting blades are attached to the wire support.

According to the weeding tool of the present invention, there are the following effects.
(1) Since the blade portion is a wire, it can be weeded with little force even with sticky soil.
(2) Since the blade portion is a wire, it is possible to easily pass the wire through the soil surface at a depth of about 10 mm. As a result, weeds can be extracted by being entangled with the wire from a position close to the surface of the soil. The movement of the soil accompanying this movement is extremely small and the work can be done with such a small force.
(3) The structure is simple, and it is easy to make the weeding width suitable for the work space by changing the size of the wire support.
(4) The length of the handle of the weeding tool can be freely changed, and can correspond to standing work and crouching work as the preferred length of the operator.

It is the whole perspective view which shows one Example of the weeding tool of this invention. The perspective view which expanded the cross section of the wire 3 attachment part provided in the front-end | tip of the wire support tool 2. FIG. And it is a perspective view of the attached wire 3. FIG. The hatched portion indicates the cut surface. 2 is a perspective view showing a wire 3. FIG.

Hereinafter, embodiments of the weeding tool of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of the weeding tool of the present invention. A U-shaped wire support 2 is attached to the tip of a handle 1, and a wire 3 is inserted into a groove 21 provided at the tip of the wire support 2. It is a thing fitted.

  At both ends of the wire 3, flanges 31 having a diameter larger than that of the groove 21 are provided so that the wire 3 cannot be detached from the wire support 2.

  The length of the wire 3 is shorter than that between the rod storage portions 22 at the distal end portion of the wire support 2.

  The wire 3 is assembled by fitting into the groove 21 with the opening of the wire support 2 narrowed by utilizing the elasticity of the wire support 2. With this configuration, the wire 3 is kept pulled at the tip of the wire support 2. By adopting this structure, the wire can be easily detached and replaced in a short time when the wire is cut or loosened.

  The wire 3 may be replaced with a metal such as a wire or a chemical fiber such as a plastic wire.

  The U-shaped wire support 2 is simple and functional in structure, but may be U-shaped. Any material can be used as long as the wire can be held by metal, wood or bamboo.

  If the wire support 2 has a rigidity capable of maintaining the shape when the wire 3 is attached and weeding, the thickness of the wire support 2 is small and the width is narrowed, so that the collapse of soil such as cocoons is reduced.

  The length of the handle 1 is about 130 cm when working in a standing state, and about 30 cm when working while crouching. The optimal length can be selected according to the physique of the worker.

  A plurality of wires can be attached to the weeding blade portion attached to the tip portion of the wire support by providing a plurality of grooves 21, and one or a plurality can be selected depending on the application. With multiple, we can cope with weeds of depth that is difficult with single.

  As the weeding blade part to be attached, a thing fixed by tightening with a screw can be selected as needed in addition to the thing fitted into the tip part of the wire support.

  The handle 1 was made of a bran material, and the thickness was a rectangle having a long side of 4 cm and a short side of 3 cm, with a corner chamfered with a radius of 5 mm, and a length of 130 cm. The wire support 2 was a steel plate having a thickness of 3 mm and a width of 2 cm, and was processed into a U shape having an opening of 20 cm and a height of 10 cm. The groove 21 of the wire support 2 was 1.5 mm wide and provided at a position 10 mm from the tip of the wire support 2. The bag storage unit 22 has a depth of 1 mm and a diameter of 6 mm. The wire 3 was a 1 mm-thick stainless steel twisted wire with a finished length of 20 cm to which the collar 31 was attached. The wire 3 was attached with a flange 31 made of a stainless steel disk having a diameter of 5 mm and a thickness of 1.5 mm at both ends. The attachment of the collar 31 was made such that a hole of 1 mm was made in the center of the collar 31 and a knot was formed on the outside of the collar 31 through the wire so that the wire did not come off from the collar 31. The inner distance of the collar 31 of the wire 3 is 204 mm between the distances 23 of the collar housing portion 22 with respect to 20 cm, and when the wire 3 is attached to the wire support 2, the wire 3 is pulled by elastic deformation of the wire support 2. Become.
