Free ground is set, and the leveling body 26 is set in a leveling work state.

次に、折り畳み連動装置3の作用について図5及び図6に基づいて説明する。図示されていないが、トラクタ座席より電動油圧シリンダ33に収縮の動作指示を与えると、電動油圧シリンダ33が収縮動作を開始し、連結された一方の回動プレート31Lは支点ピン12aを中心にミッションケース11側の中央方向へ回動動作させる。   Next, the operation of the folding interlocking device 3 will be described with reference to FIGS. Although not shown in the figure, when an operation instruction for contraction is given from the tractor seat to the electrohydraulic cylinder 33, the electrohydraulic cylinder 33 starts contracting operation, and the one rotating plate 31L connected to the fulcrum pin 12a is a mission. The case 11 is rotated in the center direction.

一方の回動プレート31Lが回動することにより、連結ロット32にて連結された他方の回動プレート31Rは支点ピン12aを中心にミッションケース11側の中央方向へ回動動作させ、左右の回動プレート31L,31Rは同時に左右対称となる内側方向に回動する。   When one of the rotating plates 31L rotates, the other rotating plate 31R connected by the connecting lot 32 rotates about the fulcrum pin 12a in the central direction on the mission case 11 side, so The moving plates 31L and 31R are simultaneously rotated in the inner direction which is symmetrical.

それぞれ同時に中央方向へ回動する左右の回動プレート31L,31Rに開口した係合孔31b,31bには、左右の砕土作業体2,2のサイドフレーム22,22より下方に突設した係合ピン22a,22aが係合される。この係合ピン22a,22aは、回動プレート31L,31Rの回動とともに係合孔31b,31bの内縁を摺動し、回動プレート31L,31Rの小さな回動角で左右の砕土作業体2,2を大きく回動させることが可能となり、左右の砕土作業体2,2は連結ピン21,21を中心に斜め後方へ折り畳み回動され、この折り畳み回動と同時にクラッチ27,27の係合は解除され、図6に示すよう砕土ロータリ24,24を入力軸11aと略同方向になるよう配置され、圃場間の移動や収納時における非作業時の折り畳み状態となる。   The engagement holes 31b and 31b opened in the left and right rotation plates 31L and 31R that respectively rotate in the central direction simultaneously project from the side frames 22 and 22 of the left and right crushed working bodies 2 and 2 below. The pins 22a and 22a are engaged. The engagement pins 22a and 22a slide along the inner edges of the engagement holes 31b and 31b as the rotation plates 31L and 31R rotate, and the left and right earth crushing work bodies 2 are rotated at a small rotation angle of the rotation plates 31L and 31R. , 2 can be pivoted greatly, and the left and right soil crushing work bodies 2, 2 are folded and pivoted obliquely rearward about the connecting pins 21, 21, and the clutches 27, 27 are engaged simultaneously with the folding pivot. Is released, and the crushed rotary 24, 24 is arranged so as to be substantially in the same direction as the input shaft 11a, as shown in FIG.

このように左右の砕土作業体2,2が非作業時の折り畳み状態となり、左右の砕土作業体2,2を構成する伝動ケース23,23の位置はほとんど変化しないので機体重心位置を大きく変化させることがなく、装着バランスの良好な状態を保持したまま非作業時の圃場間の移動を安全且つスムースに行うことができる。   In this way, the left and right crushed work bodies 2 and 2 are in a folded state when not working, and the positions of the transmission cases 23 and 23 constituting the left and right crushed work bodies 2 and 2 hardly change, so that the center of gravity position of the machine body is greatly changed. Therefore, it is possible to safely and smoothly move between the fields during non-working while maintaining a good mounting balance.

代掻き作業を行う場合は、電動油圧シリンダ33に伸長動作の指示を与え伸長動作が開始すると、連結された一方の回動プレート31Lが支点ピン12aを中心にミッションケース11に対し外方へ回動される。一方の回動プレート31Lが回動することにより連結ロット33にて連結された他方の回動プレート31Rをミッションケース11に対し外方へ回動させ、左右の回動プレート31L,31Rは同時に左右対称となる外側方向へ回転する。   When performing the scraping operation, an instruction for the extension operation is given to the electrohydraulic cylinder 33, and when the extension operation starts, one of the connected rotary plates 31L rotates outward with respect to the mission case 11 around the fulcrum pin 12a. Is done. When one rotation plate 31L rotates, the other rotation plate 31R connected by the connection lot 33 is rotated outward with respect to the transmission case 11, and the left and right rotation plates 31L and 31R are simultaneously left and right. Rotate outward in symmetry.

それぞれ同時に外方へ回動する左右の回動プレート31L,31Rに開口した係合孔31b,31bには、左右の砕土作業体2,2のサイドフレーム22,22より下方に突設した係合ピン22a,22aが係合される。この係合ピン22a,22aは、回動プレート31L,31Rの回動とともに係合孔31b,31bの内縁を摺動し、回動プレート31L,31Rの小さな回動角で左右の砕土作業体2,2を大きく回動させることが可能となり、左右の砕土作業体2,2は連結ピン21,21を中心に展開回動され、この展開回動と同時にクラッチ27,27は係合され、図5に示すように左右の砕土作業体2,2は平面視水平方向に併設され代掻き作業状態となる。   Engaging holes 31b and 31b opened in the left and right rotating plates 31L and 31R that simultaneously rotate outwardly project downward from the side frames 22 and 22 of the left and right crushed working bodies 2 and 2, respectively. The pins 22a and 22a are engaged. The engagement pins 22a and 22a slide along the inner edges of the engagement holes 31b and 31b as the rotation plates 31L and 31R rotate, and the left and right earth crushing work bodies 2 are rotated at a small rotation angle of the rotation plates 31L and 31R. , 2 can be rotated greatly, and the left and right crushed working bodies 2, 2 are unfolded and rotated around the connecting pins 21 and 21, and the clutches 27 and 27 are engaged simultaneously with this unfolding rotation. As shown in FIG. 5, the left and right crushed soil working bodies 2, 2 are provided side by side in a horizontal direction in a plan view and are in a scraping work state.

このように構成された折り畳み代掻き装置の折り畳み連動装置3は、回動プレート31L,31Rを介すことにより、電動油圧シリンダ33のシリンダストロークを短くすることができ電動油圧シリンダが小型化し、短いシリンダストロークで左右の砕土作業体を作業時の展開状態と非作業時の折り畳み状態に回動させることが可能となり折り畳み連動装置3をコンパクト且つ軽量にすることができ、機体重量を軽減し、小型トラクタへの装着も可能となる。   The folding interlocking device 3 of the folding scraping device configured as described above can shorten the cylinder stroke of the electrohydraulic cylinder 33 through the rotation plates 31L and 31R, thereby reducing the size of the electrohydraulic cylinder and reducing the length of the cylinder. With the stroke, the left and right crushed work bodies can be rotated between the unfolded state when working and the folded state when not working, and the folding interlocking device 3 can be made compact and lightweight, reducing the weight of the body and reducing the size of the tractor. It is also possible to attach to.

左右の砕土作業体2,2を構成する伝動ケースは、代掻き作業時の左右方向に水平展開した状態でトラクタの車輪後方に配置されることにより、トラクタ走行後の車輪跡に沿って伝動ケースが移動するため、圃場面に伝動ケースによる引きずり跡を形成することがなく代掻き作業が行える。   The transmission case that constitutes the left and right crushed work bodies 2 and 2 is arranged behind the tractor wheel in a horizontally deployed state in the left-right direction at the time of the scraping operation, so that the transmission case is moved along the wheel trace after the tractor travels. Since it moves, the scraping work can be performed without forming a drag mark by the transmission case in the field scene.
