Description
本発明は、コンバインのグレンタンクからトラック等へ籾を排出する排出オーガの伸縮機構に関する。 The present invention relates to an expansion / contraction mechanism for a discharge auger that discharges soot from a grain tank of a combine to a truck or the like.
従来からコンバインの座席後部にグレンタンクを配置し、穀稈を刈り取り、脱穀し、選別した後の精粒をグレンタンクに貯留し、グレンタンクがいっぱいになったり、その圃場の刈り取りが終了すると、排出オーガによって、トラックの荷台や乾燥機等に排出していた。この排出オーガはグレンタンクの側部に回動基部を設け、該排出オーガを上下に回動したり、左右に回動させて、任意の位置へ排出オーガの排出口を移動できるようにしていた。
従来の排出オーガの長さは一定であり、コンバイン本機の全長よりも短くして機体の範囲内の長さとしており、長くするためには延長オーガを取り付けることもできるが、機体幅より長くなって、走行時に障害物に当たったり、収納時にはみ出したりして、使用しづらかった。また、図５に示すように、グレンタンク３より排出オーガＣ’を用いて籾をトラックＴの荷台に排出するときに、コンバインとトラックの間が畦や川等で排出口が届き難いときがあり、また、排出口を一定にしておくと荷台上に堆積する籾は山のようになって、荷台の隅まで堆積させることができず、均一に堆積させるように、排出オーガを上下左右に旋回させるが、左右に旋回させると排出口がはみ出したり、上方へ回動すると籾が飛散したりして、機体を移動させないと所望位置に排出できないときがあり、その作業は大変面倒であった。 The length of the conventional discharge auger is constant, and it is shorter than the total length of the combine machine so that it is within the range of the aircraft. To make it longer, an extension auger can be attached, but it is longer than the aircraft width. As a result, it was difficult to use because it hit an obstacle during running or protruded during storage. In addition, as shown in FIG. 5, when discharging the kite from the Glen tank 3 to the loading platform of the truck T using the discharge auger C ′, it may be difficult to reach the discharge port between the combine and the truck due to the kite or river. Yes, if the discharge port is kept constant, the soot that accumulates on the loading platform becomes like a mountain and cannot be accumulated to the corner of the loading platform. Although it turns, if it turns left and right, the discharge port may protrude, and if it turns upward, the spear may scatter, and it may not be able to discharge to the desired position unless the aircraft is moved, which is very troublesome. .

Then, the discharge auger C is rotated to move the discharge port 13 to the input position, and the discharge conveyor and the vertical conveyor 10 provided at the lower part of the Glen tank 3 and the screw of the discharge auger C are driven, Drain the firewood.
次に、本発明の要部である排出オーガＣの伸縮機構について、図２、図３、図４より説明する。前記固定側筒１１と摺動筒１２はそれぞれパイプ状に構成して、同一軸心上に配置して、固定側筒１１の先端側に摺動筒１２を伸縮自在に外嵌している。そして、固定側筒１１と摺動筒１２が重複する先端側の両者の間にダストシール１４が介装されて、両者の間にゴミ等の異物が侵入してスムースな伸縮を阻害しないようにしている。固定側筒１１と摺動筒１２が重複する基部側には、回り止めＦを配置しており、該回り止めＦは固定側筒１１の外周面に軸心と平行にガイドレール１５・１５を固設し、一方、摺動筒１２の外周にナット１６を固設し、該ナット１６にボルト１７を螺装して、該ボルト１７先端は摺動筒１２を貫通して前記ガイドレール１５・１５の間に挿入している。１８はロックナットである。このようにして、摺動筒１２を伸縮摺動させたときに、ボルト１７先端がガイドレール１５・１５にガイドされて、摺動筒１２は固定側筒１１に対して回動することなく伸縮される。 Next, the expansion / contraction mechanism of the discharge auger C, which is the main part of the present invention, will be described with reference to FIGS. The fixed side cylinder 11 and the sliding cylinder 12 are each configured in a pipe shape, arranged on the same axis, and the sliding cylinder 12 is externally fitted to the front end side of the fixed side cylinder 11 so as to be extendable and contractible. A dust seal 14 is interposed between both ends of the fixed side cylinder 11 and the sliding cylinder 12 so as to prevent foreign matter such as dust from entering between the two and preventing smooth expansion and contraction. Yes. On the base side where the fixed side cylinder 11 and the sliding cylinder 12 overlap, a detent F is arranged. The detent F has guide rails 15 and 15 on the outer peripheral surface of the fixed side cylinder 11 parallel to the axis. On the other hand, a nut 16 is fixed to the outer periphery of the sliding cylinder 12, and a bolt 17 is screwed to the nut 16, and the tip of the bolt 17 penetrates the sliding cylinder 12 and the guide rail 15. 15 is inserted. Reference numeral 18 denotes a lock nut. In this way, when the sliding cylinder 12 is expanded and contracted, the tip of the bolt 17 is guided by the guide rails 15 and 15, and the sliding cylinder 12 expands and contracts without rotating with respect to the fixed side cylinder 11. Is done.
また、固定側筒１１と摺動筒１２の軸心部にスクリューが横架されており、該スクリューは搬送螺旋２０と移動螺旋２１と伸縮軸２５からなり、搬送螺旋２０は固定側筒１１と略同じ長さのパイプ軸２０ａの外周に螺旋状の羽根２０ｂが固設されており、パイプ軸２０ａの基部側が固定側筒１１内に固設した支持板２２にベアリング２３を介して回転自在に支持され、パイプ軸２０ａの基端部に歯車２４が固設されている。該歯車２４は縦コンベア１０のスクリューに設けた歯車と噛合され、搬出オーガＣのスクリューに動力を伝えて回動するように構成している。 Further, a screw is horizontally mounted on the axial center portion of the fixed side cylinder 11 and the sliding cylinder 12, and the screw is composed of a conveying spiral 20, a moving spiral 21, and a telescopic shaft 25, and the conveying spiral 20 is connected to the fixed side cylinder 11. A spiral blade 20b is fixed to the outer periphery of the pipe shaft 20a having substantially the same length, and the base side of the pipe shaft 20a is rotatable on a support plate 22 fixed in the fixed side cylinder 11 via a bearing 23. The gear 24 is supported and fixed to the proximal end portion of the pipe shaft 20a. The gear 24 is meshed with a gear provided on the screw of the vertical conveyor 10, and is configured to rotate by transmitting power to the screw of the carry-out auger C.
そして、前記移動螺旋２１は搬送螺旋２０の羽根２０ｂと略同じに構成され、先端の一部のみ伸縮軸２５の先端部に溶接等で固設され、移動螺旋２１の基部側は搬送螺旋２０の羽根２０ｂに重ねるように、パイプ軸２０ａ外周に巻き付けられる。伸縮軸２５は摺動筒１２と略同じ長さで、基部側がパイプ状として、その太さは前記パイプ軸２０ａに内嵌できる直径とし、前端はベアリング２７を介して排出口１３の前面に回転自在に支持され、後端はパイプ軸２０ａに軸心方向に摺動自在に挿入している。 The moving spiral 21 is configured to be substantially the same as the blade 20b of the conveying spiral 20, and only a part of the distal end is fixed to the distal end portion of the telescopic shaft 25 by welding or the like. It winds around the pipe shaft 20a outer periphery so that it may overlap with the blade | wing 20b. The telescopic shaft 25 is substantially the same length as the sliding cylinder 12, the base side is pipe-shaped, the thickness is a diameter that can be fitted into the pipe shaft 20a, and the front end rotates to the front surface of the discharge port 13 via a bearing 27. The rear end is inserted into the pipe shaft 20a so as to be slidable in the axial direction.
前記伸縮軸２５の基部側の中空部の形状は多角形またはスプライン溝に形成し、固定側筒１１の軸心部に横架した回動軸２６を中空部の形状に合わせて構成し、本実施例では六角形に構成して、伸縮軸２５と回動軸２６は互いに回転できないが、軸心方向には摺動自在に挿入している。その長さは固定側筒１１と略同じ長さとしている。そして、前記回動軸２６の基部端はモーター２９の駆動軸に連結されている。該モーター２９は正逆転可能であり、通電しない状態では回転自在としている。 The hollow portion on the base side of the telescopic shaft 25 is formed in a polygonal shape or a spline groove, and a rotating shaft 26 that is horizontally mounted on the axial center portion of the fixed side cylinder 11 is configured to match the shape of the hollow portion. In the embodiment, it is configured as a hexagon, and the telescopic shaft 25 and the rotating shaft 26 cannot rotate with each other, but are slidably inserted in the axial direction. The length is substantially the same as the fixed side cylinder 11. The base end of the rotation shaft 26 is connected to the drive shaft of the motor 29. The motor 29 can be rotated forward and backward, and is rotatable when not energized.
このように構成することで、納屋への格納時や走行時や刈取作業時等では、排出オーガＣを縮小した状態で脱穀装置Ｄ上方に収納して、機体幅よりはみ出すことがなく視界を狭めることない状態としている。そして、グレンタンク３内の籾を排出するときには、排出オーガＣを左右方向及び上下方向に回動して、排出口１３をトラック等の排出上方位置に合わせて、スクリューを駆動して排出する。このとき、排出口１３が排出位置に届かない場合や、一か所に集中して排出され均平できないときには、モーター２９を駆動して伸長させる。 By configuring in this way, when stored in a barn, during traveling, during cutting work, etc., the discharge auger C is stored in the threshing device D in a reduced state, and the field of view is narrowed without protruding beyond the body width. It is in a state that is not. Then, when discharging the soot in the Glen tank 3, the discharge auger C is rotated in the left-right direction and the up-down direction, the discharge port 13 is aligned with the upper discharge position of the truck or the like, and the screw is driven to discharge. At this time, when the discharge port 13 does not reach the discharge position, or when the discharge port 13 is discharged in a concentrated manner and cannot be leveled, the motor 29 is driven to extend.
即ち、モーター２９を駆動すると、回動軸２６が回転されて伸縮軸２５も回転する。この伸縮軸２５の回転によって移動螺旋２１が回転され、その回転によって搬送螺旋２０の羽根２０ｂに沿ってネジの如く回転しながら伸長する。このとき摺動筒１２は回り止めＦによって回転せずに伸縮軸２５とともに伸長する。逆に、モーター２９を逆方向に回転させると、一ピッチ分ズレて搬送螺旋２０の羽根２０ｂの反対面に移動螺旋２１が摺接して、摺動筒１２が縮小される。但し、歯車２４によるスクリューの駆動とモーター２９の駆動は、同時に行うことはできないようにしており、最伸長位置と最縮小位置にはリミットスイッチを配置して、排出オーガＣ設定長さ以上伸縮して壊れないように伸縮を制限している。そして、排出口１３の排出位置が設定されると、排出コンベア及び排出オーガＣのスクリューを駆動して籾の排出を行う。この時移動螺旋２１と搬送螺旋２０の羽根２０ｂが当接して、同時に回転されて、籾を排出することができる。 That is, when the motor 29 is driven, the rotation shaft 26 is rotated and the telescopic shaft 25 is also rotated. The moving spiral 21 is rotated by the rotation of the telescopic shaft 25, and the rotation is extended while rotating like a screw along the blade 20 b of the conveying spiral 20. At this time, the sliding cylinder 12 is not rotated by the detent F but is extended together with the telescopic shaft 25. Conversely, when the motor 29 is rotated in the reverse direction, the moving spiral 21 comes into sliding contact with the opposite surface of the blade 20b of the conveying spiral 20 with a shift of one pitch, and the sliding cylinder 12 is reduced. However, the drive of the screw by the gear 24 and the drive of the motor 29 cannot be performed at the same time. Limit switches are arranged at the most extended position and the most contracted position, and the discharge auger C extends or contracts more than the set length. The expansion and contraction is restricted so as not to break. And if the discharge position of the discharge port 13 is set, the screw of a discharge conveyor and the discharge auger C will be driven, and soot will be discharged. At this time, the moving spiral 21 and the blade 20b of the conveying spiral 20 come into contact with each other and are rotated at the same time to discharge the soot.
