刈刃で傷害を受けることもある。[Detailed description of the invention] When repairing or inspecting the engine section of a brush cutter or replacing the cutting blade, the work is generally done by placing the machine directly on the ground or floor with the cutting blade attached. At this time, the brush cutter has an engine at one end of the long rod and a cutting head with rotating cutting blades at the other end, so it is difficult to hold the machine during repair work, and it is difficult to hold the machine on the side during a trial run of the engine. A third party may be injured by the blade that suddenly starts rotating.
本考案は、刈払作業を除いた機械の補修作業保
管・移動等時に刈払機のすくなくとも刈刃部を簡
単に保護枠で完全に取り囲んで前記の不便さ、並
に危険性を取り除かんとするものである。 The present invention aims to eliminate the above-mentioned inconvenience and danger by easily and completely surrounding at least the cutting blade of a brush cutter with a protective frame during repair work, storage, transportation, etc. of the machine other than brush cutting work. It is something.
次に図に示す実施例にもとづき本考案を詳細に
説明する。本案の対象となる刈払機１は、長杆７
の一端にエンジン２を取着し、他端に回転刈刃３
を取着した刈取頭部４を有するものである。 Next, the present invention will be explained in detail based on the embodiment shown in the drawings. The brush cutter 1 that is the subject of this proposal has a long rod 7.
The engine 2 is attached to one end, and the rotary cutting blade 3 is attached to the other end.
The cutting head 4 has a cutting head 4 attached thereto.
この刈払機１の、刈刃３を含めて刈取頭部４全

設けて前記長杆受部９と相対して開閉・固着自在
とする。なお、骨組体５の底面を除く各面に補強
材８を対角線状に設け、さらに金網等を付すと好
適である。 A cube-like frame body 5 is provided as a removable protective frame of a size that can accommodate the entire cutting head 4 including the cutting blade 3 of the brush cutter 1. A long rod receiving portion 9 and a holding portion 10 are provided on the rear surface of the frame body 5 for holding and rotating the long rod 7. One end 11 of the presser portion 10 is pivotally attached to the frame body 5, and a fastener 12 is provided at the other end so that the holding portion 10 can be freely opened, closed, and fixed in opposition to the long rod receiving portion 9. Note that it is preferable to provide reinforcing members 8 diagonally on each surface of the frame body 5 except for the bottom surface, and to further attach a wire mesh or the like.
また、この補強材８を利用して一個又は複数個
の刈刃係止具１４を刈刃３に対して出入自在に設
ける。 Further, one or more cutting blade locking devices 14 are provided using the reinforcing material 8 so as to be able to move in and out of the cutting blade 3.
本考案による保護枠は以上の如く構成されてい

を持ち上げ、刈取頭部４を骨組体５の中に入れ、
長杆７を長杆受部９と押え部１０で挾持せしめて
締着具１２をしつかり締め付ければ、保護枠が長
杆７に対して固着される。したがつて作業中に機
体がぐらつくこともなく確実に確保され、刈刃３
が完全に枠内に入つているので不意に刈刃が回転
しても安全である。 Since the protective frame according to the present invention is constructed as described above, when repairing the brush cutter 1, etc., the holding part 10
, and place the cutting head 4 into the frame body 5.
By holding the long rod 7 between the long rod receiving part 9 and the holding part 10 and firmly tightening the fastener 12, the protective frame is fixed to the long rod 7. Therefore, the machine body does not wobble during work and is securely secured, and the cutting blade 3
is completely within the frame, so it is safe even if the cutting blade rotates unexpectedly.
また、刈刃の交換をする場合には、かかる状態
のまま天地入れ替えて刈刃３を上に向け刈刃係止
具１４を刈刃３の突出刃部（図示せず）に接当せ
しめて締着具１３で固定すると、刈刃３が上を向

業がきわめて安全・簡単に行なえる。 In addition, when replacing the cutting blade, turn the cutting blade upside down in this state, and then turn the cutting blade 3 upward and bring the cutting blade locking tool 14 into contact with the protruding blade part (not shown) of the cutting blade 3. When fixed with the fastener 13, the cutting blade 3 is restrained and fixed in an upwardly facing state so as not to rotate, making the work extremely safe and easy.
以上の如く本考案によれば、刈払機の保守・点
検作業を安全・容易に行なうことが出来る。 As described above, according to the present invention, maintenance and inspection work on a brush cutter can be performed safely and easily.
