Description

  The present invention relates to a weeding blade and a working machine with a weeding blade capable of treating weeds such as parks and fields from the root by attaching a weeding blade to a rotary small working machine.

  An electric mowing blade-equipped working machine used for cutting weeds in parks, fields, etc. has a blade on the outer periphery of a flat disk and is designed to cut the weeds by rotating the rotary blade. Although it is known, weeds could not be cut with a circular flat rotary blade, so weeds in parks, fields, etc. require labor, manpower, time, and weeds grow in a short time. There was a harmful effect.

  In addition, some mowing blades, such as stones and earth and sand, scatter and impact around them, and there is a risk of personal injury due to the rotation of the mowing blade. Some workers have a safety cover on their side. Although it exists, safety was not fully guaranteed in the event of a fall.

The above-mentioned working machine with a blade for mowing is a mowing machine for cutting a weed shortly by rotating a rotary blade along a substantially horizontal plane. It wasn't.
In addition, although a protective cover is partially provided on the worker side for safety protection, stones and earth and sand during the work are scattered around and are not adequately supported as a defensive role.

  In view of the above circumstances, in the present invention, there is no small working machine for cutting grass roots in weed processing in parks, fields, etc., so the blade for mowing is remodeled, and a plurality of bent portions are intermittently attached to the grass cutting blade body. In addition, a blade portion is provided at the bent portion, and a prevention cover is provided on the outer peripheral portion for ensuring safety.

  The weeding blade of the present invention and a cylindrical cover for preventing the danger of the cylindrical shape are provided on the outer periphery of the blade. By cutting out the roots of weeds using a blade for weeding, weeds are less likely to sprout and long-day weeds do not grow, saving labor, manpower, and time. Since the danger prevention cover is provided on the outer peripheral portion of the cutting blade, there is an effect that stones, earth and sand, etc. are scattered during weed cutting work and damage of surrounding people and articles can be prevented.

  A plurality of bent portions are intermittently provided on the grass cutting blade body, the bending angle between the horizontal surface of the grass cutting blade body and the surface of the bending portion is set to an acute angle of 20 to 90 degrees, and the outer periphery of the grass cutting blade body By using a weeding blade working machine with a cover for preventing scattering of pebbles, earth and sand, etc. on the part, weeds can be treated from the root and weed cutting can be done safely.

When the eagle two-blade main body 4 is attached to a work machine and rotated, the bent portion 3 enters deeply into the soil by the blade formed on the peripheral end surface of the bent portion 3 and cuts the root of the weed. Can do.

  FIG. 6 is a perspective view of the weeding blade of the present invention. The difference from FIG. 5 is constituted by a rectangular two-blade that is an acute blade with a bending angle of approximately 20 degrees to approximately 90 degrees with respect to the horizontal plane of the eagle two-blade body 4 of the bending portion 3. ing. The usage method of the weeding blade is the same as that of the fifth embodiment.

  FIG. 7 is a perspective view of the weeding blade of the present invention. 5 is a tip blade main body, 2 is a tip blade replacement blade hole, and 3 is a bent portion integrated with the tip blade main body. The bending part 3 has a cylindrical shape that is a sharp blade with a bending angle of approximately 90 degrees with respect to the horizontal plane of the tip blade main body 5, and has a configuration in which a blade is provided around the entire tip. By rotating the tip blade main body 5, the bent portion 3 can penetrate deeply into the soil and be cut from the roots of weeds by the blade formed on the entire periphery of the tip of the bent portion 3.

  FIG. 8 is a perspective view of the weeding blade of the present invention. The difference from FIG. 7 is that the blade is provided on the entire circumference of the tip portion in a cylindrical shape that is an acute blade with a bending angle of approximately 20 degrees to approximately 90 degrees with respect to the horizontal surface of the tip blade body 5 of the bending portion 3. It becomes more. The method of using the rotary blade for weeding is the same as in Example 7.

  FIG. 9 is a perspective view of the weeding blade of the present invention. The difference from FIG. 1 is that the bent portion 3 is a separate component from the weeding blade main body 1 and only the bent portion 3 is attached by fixing means such as a replacement blade tightening bolt 6. The blade-cutting blade body 1 is composed of a rectangular four-blade that is an acute blade with a bending angle of approximately 20 degrees to approximately 90 degrees with respect to the horizontal plane. The usage method of the weeding blade is the same as that of the first embodiment.

  FIG. 10 is a perspective view of a single bent portion 3 attached to the weed blade body of the present invention. The difference from FIG. 9 is that one of the four blades is a rectangular blade that is an acute blade with a bending angle of about 20 degrees to about 90 degrees with respect to the horizontal surface of the grass cutting blade body 1. Only the blade is shown. 7 is a replacement blade tightening bolt insertion hole for inserting a bolt or the like to attach the bent portion 3 to the blade body for weeding. Similarly to FIG. 9, the bending blade 3 is attached to the grass cutting blade main body by a fastening means such as a bolt to constitute the grass cutting blade. The usage method of the weeding blade is the same as that of the first embodiment.

  In addition, although various examples were demonstrated regarding Example 1-Example 10, the kind of blade for grassing and the angle of a bending part can also be changed in the range of 20 degree | times-90 degree | times, Of course, it can be arbitrarily changed depending on various conditions such as the shape, number of places used, weed growth status, etc., and is not limited to the examples.

  FIG. 11 is an explanatory diagram in which a weeding blade and a prevention cover are attached to a mower. 8 is a work machine arm, and a cover mounting aid 9 and an iron prevention cover 10 are attached to the work machine arm. The iron prevention cover 10 has a cylindrical shape and covers the bent portion 3 of the blade body 1 for weeding. Attach the anti-sliding cover-11 that can be moved up and down in a cylindrical shape to match the iron-made protective cover 10. The prevention cover 10 and the prevention cover 11 for sliding are not limited to metals such as iron as long as they can prevent scattering of pebbles, earth and sand, etc., and satisfy functions such as hard plastics. Of course, it can be changed if necessary.

  This sliding cover-11 has a structure that can adjust the balance between the grass blade body and the iron prevention cover-10. Reference numeral 12 denotes a bolt for preventing the cover from sliding such as a bolt for tightening the slide preventing cover 11 to the iron preventing cover 10. No. 13 uses the weeding blades of Examples 1 to 10 of the present invention according to various conditions. 14 is a presser A for attaching the blade body for weeding. 15 is a presser B for further firmly fixing the presser A for attaching the blade body for weeding. 16 is used as a working machine with blades for weeding in a state where the pressers A and B are tightened by tightening means such as a tightening nut.

  For mowing, a power mower with a rotary blade provided at the tip of the shaft is usually used, but the rotary blade is rotated along a substantially horizontal plane to cut weeds. The grass cutting blade main body is provided with a bent portion that forms a blade on the outer peripheral portion of the grass cutting blade main body, and the end portion of the bent portion has a mountain shape with a wide end of approximately 20 degrees to approximately 90 degrees. The bent part that forms the blade of the blade enters the soil and cuts it from the roots of the weeds, so that it was possible to cut the roots of the weeds manually with a working machine with blades for weeding. It can be applied to a wide range of uses.
