〔産業上の利用分野〕
この発明は、草刈機における帯刀駆動装置に関するもの
であって、農道や畦畝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 belt drive 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、例えば、実開昭６１
−９５２２７号公報に示されているように、帯刀を両側
の回転体に巻回した構成であった。Conventional blade-type mowers of this type were developed in 1983, for example.
As shown in Japanese Patent No. -95227, the belt sword 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、帯刀は、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 belt sword sometimes comes off from the position where it was attached due to the impact caused by reaping.
この発明の如く刈取装置を、特殊な素材を用いて帯状の
刃縁に構成してベルトのように駆動プーリーと縦動プー
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。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.
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。Even the accompanying drive device becomes simple, which has the advantage of being able to be manufactured at low cost as a whole.
しかし、この帯刃は、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
衝撃を受けて前記プーリーからは外れて飛び出す場合が
あった。However, if this band blade is wound around a drive pulley and a vertical pulley and is not driven while reaping,
There have been cases in which 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, or the like.
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.
この発明は、上述した課題を解決するために、次の如き
技術的手段を講する。すなわち、走行装置１と操作ハン
ドル２とを有する機体３に原動機４を搭載し、その原動
機４から伝動される駆動軸９を前方に延長して駆動プー
リーを軸着して設け。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 transmitted from the prime mover 4 is extended forward and a drive pulley is attached to the drive shaft.

１３とに帯刃１４を巻回し、前記駆動プーリー１１の背
後で下方位置に受止部材１７を設けてなる草刈機におけ
る帯刃駆動装置である。A band blade 14 is wound around the drive pulley 11 and a vertical pulley 13 provided at the tip of a support arm 12 projecting sideways from the vicinity of the drive pulley 11, and is received at a lower position behind the drive pulley 11. This is a band blade drive device for a lawn mower that is provided with a stop member 17.
原動機４を始動して、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
方向に回転する。When the prime mover 4 is started to drive each rotating part of the machine body, the band blade 14 is driven by the drive pulley 11 and rotates in the direction of the arrow.
そして、その帯刃１４は、回転にともなって草を刈り取
るときに石や木に衝突すると、プーリー１１．１３を後
側へ傾斜しようとする力を受けるまた。駆動プーリー１
１あるいは縦動プーリ−１３自体が、石などに当たって
場合も上述と同様に。When the band blade 14 collides with a stone or tree while cutting grass as it rotates, it receives a force that tends to tilt the pulleys 11 and 13 backward. Drive pulley 1
1 or the vertical pulley 13 itself hits a stone or the like, the same applies as described above.
下方が後方に傾こうとする。The lower part tends to tilt backwards.
そのときに、駆動プーリー１１は、背後から受部材１７
によって受は止められた状態にあるから。At that time, the drive pulley 11 is moved from behind by the receiving member 17.
Because Uke is in a state of being stopped by.
若干傾くと、すぐに、その受部材１７によって受は止め
られる。As soon as it tilts slightly, the receiver is stopped by the receiver member 17.
したがって、この発明は、機体全体の重量を比較的軽く
するためにプーリーを樹脂材を用いた場合でも前方から
押圧されて傾くことがほとんどなく、これによって帯刃
１４がプーリー１１．１３から外れることがないもので
ある。Therefore, in the present invention, even when the pulley is made of resin material in order to make the overall weight of the machine relatively light, it hardly tilts due to pressure from the front, and as a result, the band blade 14 does not come off the pulley 11.13. There is no such thing.
つぎに、図面に基づいて構成を説明する。 Next, the configuration will be explained based on the drawings.
機体３は、走行装置ｌｌと操作ハンドル２とを設け、原
動機４を搭載して構成している。The body 3 includes a traveling device 11, an operating handle 2, and a prime mover 4.
２０はミッションケースを示し、原動機４の回転動力を
走行装置１（車輪）と原動軸５に分配伝動できる構成と
している。Reference numeral 20 denotes a transmission case, which is configured to be able to distribute and transmit the rotational power of the prime mover 4 to the traveling device 1 (wheels) and the driving shaft 5.
伝動筒６は、上記原動軸５を内装し、基部を機体３のミ
ッションケース２０に固定し、前方に延長して伝動ケー
ス８を取り付けて構成している。The transmission cylinder 6 has the drive shaft 5 inside, has a base fixed to the mission case 20 of the fuselage 3, and extends forward to attach the transmission case 8.
そして、伝動ケース８は、前記原動軸５に連結した伝動
袋Ｎ７を内装しており、更に前方に延長した支持筒１０
に内装した駆動軸９を伝動できる構成としている。The transmission case 8 houses a transmission bag N7 connected to the driving shaft 5, and further extends forward with a support tube 10.
The structure is such that a drive shaft 9 installed inside can transmit power.
この駆動軸９は、その先端部分に駆動プーリー１１を軸
着して構成している。This drive shaft 9 has a drive pulley 11 pivotally attached to its tip.
そして、支持筒１０は、伝導ケース８に取り付けた固定
筒１５と、これに回転自由に嵌合した調節筒１６とから
構成している。。The support tube 10 is composed of a fixed tube 15 attached to the conduction case 8, and an adjustment tube 16 rotatably fitted to the fixed tube 15. .
支持腕１２は、その基部を前記支持筒１０に取り付けて
伝動ケース８の突出側とは反対側に長く延長して先端部
分に縦動プーリー１３を軸受している。The support arm 12 has its base attached to the support tube 10, extends long toward the side opposite to the protruding side of the transmission case 8, and has a vertical pulley 13 supported at its tip.
つぎに、帯刃１４は、特殊な金属を素材としてベルト状
の刃を構成し、エンドレスとして前記駆動プーリー１１
と縦動プーリー１３とに巻回して構成している。Next, the band blade 14 constitutes a belt-shaped blade made of a special metal material, and is connected to the drive pulley 11 as an endless blade.
and a vertical pulley 13.
そして、受部材１７は、第１図に示すように、駆動プー
リー１１の背後において、支持筒１０の下方に支杆１８

The roller 19 is supported by the roller 19, and the support is stopped when the drive pulley 11 tilts backward.
なお、各プーリー１１．１３は、第４図に示すごとく、
前側を大径にしたテーパー面に構成して帯刃１４の外れ
防止を行ってもよい。In addition, each pulley 11.13 is as shown in FIG.
The band blade 14 may be prevented from coming off by forming a tapered surface with a larger diameter on the front side.
以上のごとく構成して、原動機４を始動すると、回転動
力は、ミッションケース２０に達して走行装置１と原動
軸５との分配伝動される。そして、帯刃１４は、前記原
動軸５から伝動装置７、駆動軸９、駆動プーリー１１を
介して矢印の方向に駆動される。With the above configuration, when the prime mover 4 is started, the rotational power reaches the transmission case 20 and is distributed and transmitted between the traveling device 1 and the driving shaft 5. The band blade 14 is driven from the driving shaft 5 through the transmission device 7, the drive shaft 9, and the drive pulley 11 in the direction of the arrow.
このように各部を駆動して機体を前進すれば。If you drive each part like this to move the aircraft forward.
雑草は、帯刃１４によって刈り取られる。Weeds are cut by the band blade 14.
