JPH05328821A - Reaping ribbon for cutting and cleaning machine - Google Patents

Abstract

PURPOSE:To obtain a reaping ribbon for cutting and cleaning machine, rapidly decomposing pieces of reaping ribbon torn off during weed reaping, preventing the cause of environmental destruction resulting from semipermanent survival, having a bundle comprising unartificially degradable natural yarns. CONSTITUTION:In a reaping ribbon 24 for cutting and cleaning machine 10, artificially degradable natural yarns 26 composed of vegetable fibers such as cotton yarn or hemp yarn are twisted to form a bundle 30. The bundle 30 is coated with an unartificially degradable natural binder 28 such as glue in a liquid state and dried to make the natural yarns 26 in a mutually stuck state. After drying, the bundle 30 is coated while maintaining the surface smooth to give the objective reaping ribbon 24 for cutting and cleaning machine, rapidly degradable, capable of preventing destruction of environment even if the reaping ribbon is torn off or cut by using the cutting and cleaning machine 10 and allowed to stand. The two reaping ribbons 24 are fixed from a rotary head 20 attached to a driving shaft 22 projected downward from a gear case 18 fitted to the lower end part of a pipe 10 of the cutting and cleaning machine 24 to mutually opposite parts and used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush clip for a brush cutter, and more particularly to a clip cable for a brush clip suitable for environmental protection.

[0002]

2. Description of the Related Art A conventional clip string for a brush cutter is made of an artificial fiber such as nylon. (Example: JP-A-61-1703
No. 10 and Japanese Patent Laid-Open No. 63-59812).

[0003]

The mowing string for the brush cutter may be torn or cut on the tip side when mowing the grass, but with the conventional mowing string, it is torn and left on the ground or the like. The fragment of the cut string that did not corrode does not corrode and remains semi-permanently between grass and flowers, which is one of the environmental damage. In addition, small animals such as small birds sometimes suffocate and die by mistakenly swallowing a fragment of a torn string.

It is an object of the invention of claim 1 to provide a cutting string for a brush cutter, which can prevent environmental damage due to a torn piece. The object of the invention of claim 2 is that
An object of the present invention is to provide a mowing string for a brush cutter, which has improved cuttability and strength during mowing.

[0005]

The present invention will be described using reference numerals in the drawings corresponding to the embodiments. The cutting string (24) for the brush cutter (10) according to claim 1 has a bundle (30) made of naturally decomposable natural fibers (26).

The cutting string (24) for the bush cutter (10) according to claim 2 further comprises a natural degradable natural adhesive (28) applied to the bundle (30) so as to cover the bundle (30). )have.

[0007]

In the cutting string (24) for the brush cutter (10) according to claim 1, the fragments of the bundle (30) that have been left in a state of being torn or cut due to use are being made rainy or the like. , Decomposed by microorganisms, ultraviolet rays, etc. and absorbed or mixed with soil.

In the cutting string (24) for the brush cutter (10) according to claim 2, the natural adhesive (28) of the cutting string (24) that has been torn or cut due to use and left in a standing state is Together with the bundle (30) covered with, while being exposed to rain or the like, it is decomposed by microorganisms, ultraviolet rays, etc., and is absorbed or mixed in the soil. The natural adhesive (28) is applied in a liquid state to the bundle (30) of natural fibers (26) and dried to fix the natural fibers (26) to each other. After drying, the bundle (30) is covered while maintaining a smooth surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 5 is a schematic overall view of the brush cutter 10. pipe
A power unit 14 is attached to the upper end of 12 and the handle 16 is
It is fixed to the pipe 12 near the power unit 14 and projects upward. The gear case 18 is attached to the lower end of the pipe 12, and the rotary head 20 is fixed to a drive shaft 22 projecting downward from the gear case 18 and rotates integrally with the drive shaft 22.
The two cutting strings 24 extend outward from diametrically opposite portions of the peripheral portion of the drive shaft 22.

1 and 2 are a detailed side view and a cross-sectional view of the cutting cord 24, respectively. The cutting string 24 is composed of a bundle 30 in which vegetable fibers 26 such as cotton yarn and hemp yarn are twisted together. Bundle 30
Is cut off or cut from the tip side with use, but the fragments of the cutting string 24 that are torn off and left on the ground etc. are composed of a bundle 30 made of natural adhesive 28. While being exposed to rain or the like, the natural adhesive 28 is decomposed by microorganisms, ultraviolet rays, or the like, and is absorbed or mixed with soil.

3 and 4 are detailed side and cross-sectional views, respectively, of a clip 24 having a natural adhesive 28. In this cut string 24, a natural adhesive 28 such as glue is applied to the bundle 30 in a liquid state with respect to the cut string 24 of FIGS. 1 and 2, and dried. The dried natural adhesive 28 fixes the plant fibers 26 to each other and makes the surface of the cutting string 24 smooth. As a result of the mutual adhesion of the plant fibers 26 due to the adhesive function of the natural adhesive 28, the strength of the cutting string 24 is increased. Further, the surface treatment of the cutting string 24 with the natural adhesive 28 improves the cutting property of the cutting string 24 when cutting grass. In the cutting string 24 that is torn off and left on the ground or the like, the natural adhesive 28 is decomposed by microorganisms, ultraviolet rays, and the like together with the plant fiber 26 of the bundle 30, and is absorbed or mixed in the soil.

In the illustrated embodiment, vegetable fiber 26 is used, but naturally decomposable animal fiber such as wool is used as the vegetable fiber.
It is also possible to use instead of 26.

[0013]

According to the invention of claim 1, since the bundle of cutting strings for the brush cutter is made of natural fiber which can be decomposed naturally instead of the conventional synthetic fiber, even if it is torn and left as it is. ,
It can be quickly decomposed to prevent environmental damage.

According to the second aspect of the present invention, since the natural adhesive applied to and covering the bundle is also capable of being naturally decomposed, the cut cord fragments that have been torn and left as they are, together with the bundle,
It can be quickly decomposed to prevent environmental damage. Further, the natural adhesive fixes the natural fibers to each other to increase the strength of the cutting string and smoothes the surface of the cutting string to improve the cutting property of the cutting string when mowing the grass.
