Definitions

• a plurality of mowing blades provided at a front portion of a metal substrate for weeding are intermittently retracted inward, and a predetermined width is continuously formed inside the mowing blades.
• Weed rhizomes at a predetermined depth or near the ground such as by protruding a protruding piece that can prevent a collision with a mold object, or by forming a protruding piece on a warp to prevent the lawn from engaging in roots, etc.
• the present invention relates to a manual or prime mover for weeding with a mowing blade.
• weeding tools also referred to as grasses
• Fig. 7 Conventionally, weeding tools (also referred to as grasses) as shown in Fig. 7 have been mainly used in agricultural lands and gardens except paddy fields. Cutting with a blade.
• the forked grasses shown in Fig. 8 are used manually, but each time the grass is extracted one by one, it is convenient to remove the grass roots because the rhizome enters the sharp blade inside the protruding piece. Is good, but it takes time to remove it.
• the bifurcated grass in Fig. 9 improves the inside of the sharp bifurcated grass described above, and since the inside has an extra space in the shape of an arc, it is the same as the previous example that the rhizome that has been bitten is removed. Although it is simple, it has to be pierced one by one into the soil and then lifted and pulled out, so that continuous work is not possible and it is extremely troublesome.
• the rake-type grass shown in Fig. 10 also has no effective cutting blade for cutting the rhizome, and the protruding piece gradually narrows in the direction of the front end, and has an arc shape at the front end. Formed, no effective cutting blade. Therefore, for example, even a soft rhizome has to be driven into the surrounding soil at a predetermined depth, hooked on a protruding piece, and pulled out with force.Therefore, a narrow flowerbed or a large farmland garden that can be used for planting, etc. Etc., and it was impossible to cut soft rhizome weeds mixed in the lawn.
• weeding blades are provided with intermittently provided cutting blades intermittently provided at a front portion of a metal substrate for weeding, which are drawn inward and formed to have a predetermined width continuously and sharply.
• the desired shape of the protruding piece and the direction of the protruding slightly differ depending on the conditions of the land to be weeded, but in general the protruding piece is also wide and forms a front blade and protrudes forward. .
• the width of the protruding pieces is preferably equal to the width of the front piece, that is, it is preferable that the distance between the protruding pieces is substantially the same in the inner depth direction. At the same time, the roots of the weeds in the inner part can easily fall off, and the continuity of the work can be improved.
• a weeding tool for hand work is realized by providing a handle on the metal substrate for weeding as described above, or a push-pull type weeding tool in which the handle is swingably or slidably attached to heavy wheels. It can be used as a metal substrate for blasting, and enables continuous weeding work without driving. Further, the invention is to provide a weeding tool for attaching the above-mentioned metal substrate for weeding to a rotating body interlocked with a support wheel, and rotating it manually or by a motor.

• the above-mentioned weeding tool 1 has a handle, and when the metal substrate 2 for weeding is lightly hammered into the ground at about 30 degrees and pulled toward the front, the front blade, which is the tip of the protruding piece, is sharp, so the back blade is sharp. Almost reach the level of, cut the grass roots in the shallow layer and cut the rhizome between the prongs with the back blade.
• solids smaller than between the front blades are lighter in weight and touch in a floating state, so the impact is small and the sharpness of the rear blade is maintained for a long time.
