Description

  The present invention relates to a cutting blade cover that covers a cutting blade so as not to damage a person or an object when carrying a brush cutter.

The brush cutter transmits the power of the driving device (small engine or electric motor) attached to the rear end of the main pipe to the cutting blade at the tip of the main pipe through the drive shaft in the main pipe, and rotates the cutting blade to remove grass and small diameters. For example, an operator operates a handle fixed to an intermediate portion of the main pipe to perform the mowing work (see, for example, Patent Document 1 and Non-Patent Document 1).
Such a brush cutter is used for the brush cutting work in forests, farms, gardens, fields, roads, etc., and can significantly reduce the working time compared with the case of manual work with grass scythe etc. It is widely used mainly in the workplace of civil engineering and construction business.

While the brush cutter can greatly improve the efficiency of the brush cutting operation, the cutting blade rotates at a high speed, and therefore, a scattering prevention cover for preventing the operator from directly hit the scattered object (for example, see FIG. 1). No. 6 “Spattering prevention cover 105” and Non-Patent Document 1 “Pattern prevention cover” on page 10), and the operator himself must wear protective equipment. It is. In addition, even when not in use, the sharp edge of the cutting blade is exposed at the end of the long main pipe, so it is necessary to take safety measures to avoid damaging people and objects. When storing or transporting the dispenser, it is necessary to attach a cutting blade cover that covers the cutting blade (for example, “cutting blade cover” on page 19 of Non-Patent Document 1 and “cutting blade” of Patent Document 2). (See Safety cover).
Here, the cutting blade cover of Non-Patent Document 1 is a belt-shaped one made of synthetic resin, and is wound around the outer peripheral edge of the cutting blade and then fastened at both ends with fasteners.
Further, the cutting blade cover of Patent Document 2 is a bag-shaped one made of rubber, synthetic resin, or cloth and having an outer shape that is substantially U-shaped. The flap-shaped lid (6) is opened, and the cut (3) After the cutting blade (8) is inserted in a state where the blade is spread left and right, the lid (6) is closed.

The conventional cutting blade cover such as Non-Patent Document 1 has a configuration in which a band-shaped cutting blade cover is wound around the outer peripheral edge of the cutting blade and both ends are fastened with fasteners, so that attachment and detachment is troublesome. There is a risk of injury due to the finger hitting the blade during attachment / detachment.
Moreover, the conventional cutting blade cover like patent document 2 is easy to attach and detach compared with non-patent document 1, but since the outer shape is substantially U-shaped, a scattering prevention cover (for example, the figure of patent document 1). 6 (see “Spattering prevention cover 105” in FIG. 6 and “Spattering prevention cover” on page 10 of Non-Patent Document 1) are attached near the tip of the brush cutter. On the other hand, the cutting blade cover cannot be attached or the attachment becomes difficult.
Furthermore, the blade cover as in Non-Patent Document 1 and Patent Document 2 needs to store the blade cover removed from the blade when using the brush cutter, and therefore may be lost. When you want to use it, you may not be able to use it immediately.

  Therefore, in view of the situation described above, the present invention intends to solve the problem that it is easy to attach and detach, and even if the anti-scattering cover is attached near the tip of the brush cutter, it is easy to install and is lost. The present invention provides a cutting blade cover for a brush cutter that can be used immediately when it is desired to use without fear.

  In order to solve the above problems, the brush cover for a brush cutter according to the present invention is attached to the brush cutter when storing or transporting a brush cutter that performs grass or small diameter tree cutting work while rotating the blade.
