Abstract

(57) [Summary] [Purpose] To provide a blade of a brush cutter capable of simultaneously cutting leaves, stems, and roots. [Structure] A root cutting blade (3) is provided on a lower surface (2) of a rotary blade (1).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blade of a brush cutter having a root cutting blade provided on a lower surface of a rotary blade.

[0002]

[Prior art]

 In the past, the blades of brush cutters used to rotate a saw-toothed disk to cut grass leaves and stems.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. Since the roots under the ground cannot be cut, they will germinate again from the roots in a short period of time, so it was necessary to either pull out the roots one by one or mow the grass many times in a short period of time. Moreover, short grass could not be cut with a rotary blade. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 A root cutting blade (3) is provided on the lower surface (2) of the rotary blade (1). This root cutting blade (3) may be a projection (4) as in the embodiment introduced later. And the number of the root cutting blades (3) may be one or two or more. The protrusions (4) may be V-shaped or J-shaped as in the examples introduced later. The number of protrusions (4) may be one or two or more.

[0005]

[Action]

 While rotating the rotary blade with the root cutting blade of the present invention with a motor or an engine, move it back and forth, left and right, while cutting long grass with the rotary blade while pressing the root cutting blade against the ground Cut short grass and roots with.

[0006]

Example 1 Example 1 will be described with reference to FIG. In the first embodiment, the root cutting blade (3) is provided on the lower surface (2) of the rotary blade (1).

Second Embodiment A second embodiment will be described with reference to FIG. In the second embodiment, the root cutting protrusion (4) is provided on the lower surface (2) of the rotary blade (1).

Third Embodiment A third embodiment will be described with reference to FIG. In the third embodiment, the protrusions (4) are V-shaped.

Fourth Embodiment A fourth embodiment will be described with reference to FIG. In the example 4, the protrusions (4) are J-shaped.

[0010]

[Effect of device]

 Since the roots under the ground can be cut, it is possible to mow without regrowth over a long period of time, and at the same time the ground is swirled to level the ground. Also, by exchanging the root cutting blade, you can mow regardless of the size of the grass.
