ものであって、農道や畦道等の草刈りに利用できるもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a grass clipping prevention device for a grass cutter, and can be used for mowing farm roads, ridges, etc.
従来のこの種の帯刀式の草刈機は１例えば、実開昭６１
−９５２２７号公報に示されているように、帯刃を両側
の回転体に巻回した構成であった。Conventional sword-type grass cutters of this type are 1, for example,
As shown in Japanese Patent No. -95227, the band blade was wound around rotating bodies on both sides.
この構成によると、刈刃の構成と、これに付随する伝動
装置の構成が簡単にはなるが、安全性に関し問題があっ
た。According to this configuration, the configuration of the cutting blade and the configuration of the transmission device accompanying it are simplified, but there is a problem regarding safety.
すなわち、帯刃は、刈取に伴う衝撃により取付けた位置
から離脱することがあった。That is, the band blade sometimes comes off from the installed position due to the impact caused by reaping.

リーとに巻回した構成にすると、刈刃そのものの構成が
簡単となるばかりでなく、これに付随する駆動装置まで
もが簡単となり、全体として安価に製作できる利点があ
る。If the reaping device of this invention is constructed with a belt-shaped blade edge made of a special material and wound around the drive pulley and vertical pulley like a belt, the construction of the reaping blade itself becomes simple. Not only that, but even the accompanying drive device becomes simple, and the overall advantage is that it can be manufactured at low cost.
しかし、この帯刀は、駆動プーリーと縦動プーリーとに
巻回した状態で駆動しなから刈取作業を行っていると、
刈取に伴う衝撃を受けたり、石、木、竹などに衝突して

あった。However, if this belt knife is wound around a drive pulley and a vertical pulley and is not driven while reaping,
There have been cases where the blade has come off the pulley and jumped out due to the impact caused by reaping or by colliding with a stone, tree, bamboo, etc.
上述の現象は、帯刃が刃物であるだけにきわめて危険で
安全対策が要求されていた。The above-mentioned phenomenon is extremely dangerous since the band blade is a cutlery, and safety measures are required.

持部１７を設けてなる草刈機における刈草巻付防止装置
である。In order to solve the above-mentioned problems, the present invention takes the following technical measures. That is, a prime mover 4 is mounted on a body 3 having a traveling device 1 and an operating handle 2, and a drive shaft 9 is extended so as to take out the rotational power of the prime mover 4 forward.
A support arm 12 is provided with a drive pulley 11, and a support arm 12 whose base is attached to a support tube 10 containing the drive shaft 9 and extends laterally.
A vertically moving pulley 13 is provided at the tip of the vertically moving pulley 13.
A band blade 14 is wound around the driving pulley 11, and a holding part 17 is provided at the corner where the lower reaping side of the band blade 14 and the driving pulley 11 start winding to sandwich the band blade 14 from above and below. This is a grass clipping prevention device for a grass cutter.
原動機４を始動して１機体の回転各部を駆動すると、帯
刃１４は、駆動プーリー１１によって駆動されて矢印の

を回転にともなって側方に搬送しながら両プーリー１１
．１３の間から後方へ排出する。During such work, the band blade 14 rotates and conveys the cut grass to the side while moving it to both pulleys 11.
．． Discharge from between 13 to the rear.
そのとき、刈取られ帯刃１４の上面に載った状態で駆動
プーリー１１の方向に搬送される草は。At this time, the cut grass is conveyed toward the drive pulley 11 while resting on the upper surface of the band blade 14.
駆動プーリー１１の近くに達すると帯刃１４の上下両面
から挟むように設けている保持部１７に２取り除かれて
帯刃１４から後側に排出される。When it reaches the vicinity of the drive pulley 11, it is removed by the holding portions 17 provided to sandwich it from both the upper and lower sides of the band blade 14, and is discharged from the band blade 14 to the rear side.
この場合、帯刃１４は、駆動プーリー１１の近くで上か
らだけでなく下側からも保持されているから、上面に載
った草が無理に帯刃１４を押し下げて上側の保持部との
間に入り込もうとしても阻止できる特有のものである。In this case, since the band blade 14 is held near the drive pulley 11 not only from above but also from below, the grass on the top surface may forcefully push down the band blade 14, causing a gap between the band blade 14 and the upper holding part. It is a unique feature that can prevent any attempt to enter.
