Therefore, the operator may not know whether to pass the wrapping prevention linear member 41 in front of or behind the rotation direction of the tillage claw 32 at the time of attaching the wrapping prevention linear member 41.

そこで、図7および図8に示すように、耕耘軸31の軸本体部36および爪ホルダー部37のうち少なくともいずれか一方、すなわち例えば軸本体部36の外周面には、作業者に対して巻付防止線状部材41の通し方を示す目印手段42が設けられている。 Therefore, as shown in FIGS. 7 and 8, at least one of the shaft main body 36 and the claw holder 37 of the tillage shaft 31, that is, for example, the outer peripheral surface of the shaft main body 36 is wound around the operator. A marker means 42 is provided to indicate how to pass the sticking prevention linear member 41.

そして、目印手段42は、例えば図7(a)に示す前用目印42aおよび図7(b)に示す後用目印42bからなるものである。 The marking means 42 is composed of, for example, the front marking 42a shown in FIG. 7A and the rear marking 42b shown in FIG. 7B.

前用目印42aは、巻付防止線状部材41を通す位置が回避対象の耕耘爪32の回転方向前方側の位置であることを示す点状目印(例えば溶接盛)である。この前用目印42aは、軸本体部36の外周面のうち、回避対象の耕耘爪32の回転方向前方側の位置、つまり回避対象の耕耘爪32が取り付けられた爪ホルダー部37の回転方向前面37aの下端近傍位置に膨出状に設けられている。 The front mark 42a is a point mark (for example, a welding pile) indicating that the position through which the winding prevention linear member 41 is passed is the position on the front side in the rotation direction of the tillage claw 32 to be avoided. The front mark 42a is a position on the outer peripheral surface of the shaft main body 36 on the front side in the rotation direction of the tillage claw 32 to be avoided, that is, the front surface in the rotation direction of the claw holder portion 37 to which the tillage claw 32 to be avoided is attached. It is provided in a bulging shape near the lower end of 37a.

後用目印42bは、巻付防止線状部材41を通す位置が回避対象の耕耘爪32の回転方向後方側の位置であることを示す点状目印(例えば溶接盛)である。この後用目印42bは、軸本体部36の外周面のうち、回避対象の耕耘爪32の回転方向後方側の位置、つまり回避対象の耕耘爪32が取り付けられた爪ホルダー部37の回転方向後面37bの下端近傍位置に膨出状に設けられている。 The rear mark 42b is a point mark (for example, a welding pile) indicating that the position through which the winding prevention linear member 41 is passed is the position on the rear side in the rotation direction of the tillage claw 32 to be avoided. The rear mark 42b is a position on the outer peripheral surface of the shaft main body 36 on the rear side in the rotation direction of the tillage claw 32 to be avoided, that is, the rear surface in the rotation direction of the claw holder portion 37 to which the tillage claw 32 to be avoided is attached. It is provided in a bulging shape near the lower end of 37b.

なお、回避対象の耕耘爪32は、複数の耕耘爪32のうち、巻付防止線状部材41を耕耘軸31の軸方向(左右方向)に沿って真っ直ぐな一直線状に配設しようとした際に障害となる耕耘爪(爪ホルダー部37の大きさや形状等によっては、耕耘爪ではなく爪ホルダー部が障害となる場合もある)を意味する。 The tillage claw 32 to be avoided is a case where, of the plurality of tillage claws 32, the winding prevention linear member 41 is to be arranged in a straight line along the axial direction (left-right direction) of the tillage shaft 31. It means a cultivated claw that becomes an obstacle (depending on the size and shape of the claw holder portion 37, the claw holder portion may be an obstacle instead of the cultivated claw).

次に、農作業機1の作用等を説明する。 Next, the operation and the like of the agricultural work machine 1 will be described.

例えば農作業機1の組立時や部品交換時等において、耕耘爪32をすべての各爪ホルダー部37に取り付けた後、巻付防止線状部材41を耕耘軸31に取り付ける場合には、作業者は、目印手段42の目印42a,42bをみて、巻付防止線状部材41を通す位置を確認しながら回避対象の耕耘爪32を回避して巻付防止線状部材41を通す。 For example, when assembling the agricultural work machine 1 or exchanging parts, when the tilling claw 32 is attached to all the claw holders 37 and then the winding prevention linear member 41 is attached to the tilling shaft 31, the worker , Looking at the marks 42a and 42b of the mark means 42, while confirming the position through which the wrapping prevention linear member 41 is passed, avoid the tilling claw 32 to be avoided and pass the wrapping prevention linear member 41.

このため、作業者は、巻付防止線状部材41を耕耘爪32の回転方向前後のどちらに通せばいいのか分からなくなることがなく、耕耘軸31に対して巻付防止線状部材41を容易に取り付けることが可能である。 Therefore, the operator does not have to know whether to pass the wrapping prevention linear member 41 in the front or rear of the rotation direction of the tilling claw 32, and the wrapping prevention linear member 41 can be easily passed with respect to the tilling shaft 31. It can be attached to.

このように、農作業機1によれば、巻付防止線状部材41を通す位置の目安となる目印手段(前用目印42aおよび後用目印42b)42を備えるため、作業者は、巻付防止線状部材41の取付作業を容易に行うことができ、作業者の負担を軽減できる。 As described above, according to the agricultural work machine 1, since the marking means (front mark 42a and rear mark 42b) 42 that serve as a guide for the position through which the wrapping prevention linear member 41 is passed is provided, the operator can prevent wrapping.
