Abstract

(57) [Abstract] [Purpose] The present invention relates to a blade of a brush cutter, which is made of metal and has a nylon thread attached to the blade of the brush cutter. [Structure] A hole (2) is made in the blade (1) of a metal brush cutter, and a nylon thread (3) is passed through the hole (2).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a blade of a brush cutter.

[0002]

[Prior Art]

 Up until now, either a metal blade or a nylon cutter was selected according to the place to be mowed, and it was attached to a brush cutter and used.

[0003]

[Problems to be solved by the device]

 With the method that uses two types of blades as described above, it takes time and effort to replace the blades. In addition, a nylon cutter cannot mow thick roots or hard grass, and the grass mowed up soars to the face and body. Since it adheres, there is a drawback in that it becomes necessary to wear protective glasses and change clothes after the work. The problem to be solved by this device is that it can be used even in the presence of obstacles such as stones, it enables to mow thick roots and hard grass, and prevents the mowed grass from flying high. .

[0004]

[Means for Solving the Problems]

 The inventor of this device was able to complete this device by thinking that a blade of a brush cutter that would solve the above-mentioned problems could be made, and was able to attach a nylon thread to a metal blade. Now, the solution means will be described with reference to the drawings. (A) A hole (2) is made in each of the blades (1) of the brush cutter made of gold and iron. (B) Pass the nylon thread (3) through the hole (2). It should be noted that the hole (2) may be provided with a spigot (4) as in an embodiment introduced later.

[0005]

Since the present invention has the above-mentioned structure, it is used by being mounted on the electric brush cutter. When replacing the nylon thread, pull out the nylon thread from the hole and insert a new nylon thread.

【Example】

 Example 1 FIG. 1 is a plan view showing Example 1. Make a hole (2) in the blade (1) of the metal brush cutter and pass the nylon thread (3) through the hole (2).

Second Embodiment FIG. 3 is a plan view showing a second embodiment. Insert the eyelets (4) into the holes (2) and thread the nylon thread (3) through the holes (2) with the eyelets (4). The interference (4) reduces the friction between the hole (2) and the nylon thread (3), and allows the nylon thread to last longer. In addition, even if the number of holes (2) is four or more, the effect can be achieved without changing the effect.

[0008]

[Effect of the device]

 In this invention, the nylon thread acts even on the outside of the metal blade, so that the grass can be mowed even when there is an obstacle such as a stone without damaging the metal blade. In addition, the metal blade acts as a cover to prevent grass that has been mowed with nylon thread from rising and adhering to crops and the body, and also mowing thick roots and hard grass. be able to.
