JP2003000027A - Hair clipper type blade device for mowing machine - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a hair clipper type blade device without having a danger of touching the blade with a stone, concrete wall surface or the like, being broken by an impact and scattering, capable of being used in mowing the verge of the wall surface by changing its angle in a direction for ease of its use and freely attachable and detachable with a mowing machine. SOLUTION: This mowing machine equipped with a rotary part at the tip of a hollow cylinder attaching a mowing blade thereto, also installing an engine at its rear end, and joining the rotary part and the engine with a shaft for rotating them as interlocked, is provided by attaching a tightening for holding plate which is fit to the rotating part having a rotation-fixing hook and mounted to the hollow cylinder at the rotary part and a supporting plate installed at the hair clipper type blade device as freely attachable and detachable. The hair clipper type blade is actuated by altering the rotation from the rotary part with a crank device and a means capable of changing the angle of the hair clipper type device within 180 degree range with an angle-adjusting part installed at the surroundings of the above rotary part, and also changing the angle of the hair clipper type blade device 5 in an up and down direction with adjusting holes installed at the above tightening for holding plate is provided.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clipper blade device which can be detachably attached to the tip of a brush cutter. 2. Description of the Related Art Conventionally, a brush cutter uses a brush cutter blade at the tip and does not use a clipper blade. There was one. [0003] In the conventional brush cutter, a mowing blade or a nylon cutter for mowing is used. However, there is a danger that the blade will be blown and scattered, and there is also a problem that the cutter part has a danger due to high-speed rotation of the brush cutter. According to the present invention, there is no danger of the blade touching a stone or concrete wall surface and being crushed and scattered, and can be used by cutting the wall surface or the like and displacing the angle in an easy-to-use direction. It is an object of the present invention to provide a clipper blade device for a brush cutter. [0005] In order to achieve the above-mentioned object, a rotary portion is provided at the tip of a hollow cylinder, a brush cutter is provided, and an engine is provided at a rear end. In a brush cutter that rotates on a shaft, it is fitted with a rotating part with a rotating fixing hook on the rotating part, and the fastening holding plate attached to the hollow cylinder and the support plate provided on the clipper blade device are removable. The clipper blade is operated by changing the rotation from the rotation unit with a crank device, and the angle of the clipper blade device is adjusted by 180 degrees by an angle adjustment unit provided around the rotation unit.
Means is provided that can be displaced within a range of degrees, and that the angle of the clipper blade device can be displaced in the vertical direction by adjusting holes provided in the fastening holding plate. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In the embodiment shown in FIGS. 1 and 2, a brush cutter blade 5 is attached to a tip of a hollow cylinder 1, and a rotary cutter 2 is attached to a tip end of a hollow cylinder 1. A rotation unit 7 to which the rotation fixing hook 6 is attached, and an angle adjustment unit 8 around the rotation unit 7;
The rotary fixing hook 6 of the rotary unit 7 and the rotary unit 2 of the bush cutter 4 are fitted to each other, a fastening holding plate 9 is attached below the hollow cylinder 1 of the bush cutter 4, and the fastening holding plate 9 and the clipper blade device 5 is screwed onto a support plate 10 provided at a rear portion of the clipper 5, and the rotation from the rotating portion 2 is changed by a crank device 11 so that the clipper blade 12 operates. Is detachable, the bolt 13 of the angle adjusting unit 8 is loosened, and the angle of the clipper blade device 5 can be displaced within a range of 180 degrees to the left and right. The angle of the device 5 can be vertically displaced. Since the present invention is configured as described above, it has the following effects. [0008] The clipper blade device for a brush cutter according to the present invention comprises a stone,
There is no need to worry about the blade touching the concrete wall and blasting and scattering.
It can be displaced up to 80 degrees and can also be displaced in the up and down direction, so it can be attached to and detached from the bush cutter, so that it can be replaced with a bush cutter according to the grass cutting situation, and the convenience and efficiency of work can be obtained. Things.
