Abstract

PROBLEM TO BE SOLVED: To prevent a protective cover attached to the lower side of a cutting blade from being in contact with the ground and wear when performing a brushing operation with a brush cutter, and to lift the cutting blade from the ground so that the cutting blade does not contact the ground This eliminates the inconvenience that is a burden on the operator and that the grass is wrapped around the rotary shaft of the brush cutter from the gap between the protective cover and the cutting blade attached to the lower side of the cutting blade. thing.
SOLUTION: A protective cover is made large and a bearing is attached inside so that it can freely rotate without being affected by the rotation of the cutting blade. Also, grass is wrapped around the rotating shaft inside the protective cover. This problem is solved by attaching a metal plate to prevent.

Description

The present invention relates to a universal ground stabilizer for a brush cutter that is attached to the lower side of a cutting blade of a brush cutter to improve the work function and reduce the burden on the operator.

Conventionally, a protective cover for preventing wear and damage of bolts and nuts that fix the cutting blade to the rotary shaft of the brush cutter is attached to the lower side of the cutting blade of the brush cutter. The plate was simply formed into a bowl shape, and it was fixed to the cutting blade and rotated together.

1) However, since the protective cover rotates at a high speed with the protective cover in contact with the ground during mowing, it wears out quickly. Further, since the operator works with the cutting blade floating from the ground so that the cutting blade is not in contact with the ground as much as possible, it is a burden on the operator.
2) Also, during the mowing operation, the grass wraps around the rotary shaft of the brush cutter through the gap between the cutting blade and the protective cover, and the rotation stops. Shrink.

1) Install a grounding stabilizer larger than the conventional protective cover, and attach a bearing to the center of the stabilizer. By attaching to the rotary shaft of the brush cutter through this bearing, the grounding stabilization board rotates freely without being affected by the rotation of the cutting blade.
2) Install a metal plate to prevent the grass from winding around the rotating shaft inside the ground stabilizer.

1) Compared to a conventional protective cover, it is not fixed to the cutting blade and rotates freely, so there is little wear even if mowing is done on the ground. In addition, since the operator can perform mowing work with the grounding stabilization board in contact with the ground, the burden on the worker is greatly reduced.
2) Since the grass does not wind around the rotary shaft of the brush cutter during the mowing operation, the work efficiency is improved, the burden on the brush cutter is greatly reduced, and the life is extended.

As shown in FIG. 1, a flat ground recess is formed at the center of the stabilizer so that the mounting bolt 2 at the center does not come into contact with the ground and is damaged. . A bearing 3 is attached to the center of the stabilizer, and the ground stabilizer is attached to the rotary shaft of the brush cutter through this bearing, so that it freely rotates without being affected by the rotation of the cutting blade.
In addition, several metal plates 4 that prevent grass from winding around the rotating shaft are attached to the inside of the stabilizer.
If the height of the stabilization board is too low, the cutting blade will easily come into contact with the ground, and if it is too high, the grass will be short and cannot be mowed.
The attachment method to the brush cutter is a structure that can be easily attached and detached with only one bolt at the center of the ground stabilization board.
Can be mounted on the underside of any mowing blade, tip saw, or resin blade mowing blade for a brush cutter. Also, as shown in Fig. 4, the lower side of the cutting blade protection panel to protect the cutting blade from obstacles A structure that can also be mounted on.
The material is hard to rust, is a thin metal plate, and has a strength that does not wear even if it is in contact with the ground for a long period of time.
