Description

本発明は、脱粒後の排稈をフィードチェンから排藁チェンに受継ぎ、機体後方に排出する搬送体を装備し、該搬送体を上下回動可能に支持したコンバインの排藁搬送装置に関するものである。   TECHNICAL FIELD The present invention relates to a combine waste transporting device that is equipped with a transport body that inherits drainage after sheding from a feed chain to a waste chain and discharges it to the rear of the machine body, and that supports the transport body so that it can be turned up and down. It is.

従来、フィードチェンに連設して斜搬送する排藁チェンの受継ぎでは、搬送方向が屈折することから排稈の詰まりや稈抜けが発生し易くなり、整備点検をするために排藁室の床面に弾持した排藁ガイド棒に対して、搬送体を固着するロック装置を解除させ、補強用の排稈フレームを回動支点にして上方に開放すると、該搬送体が支持フレームとともに上昇して前記排藁ガイド棒との間隔が広がり、容易にメンテナンスを行える構造にしたものがある（例えば特許文献１参照。）。しかしながら、搬送体を取付けたフレームが排藁チェンの上方を通過する構成であり、回動中心が駆動ケースよりも高い位置になって扱胴軸と入力軸との軸間が変動し、入力ベルトを外す操作をともなう回動搬送体である。
特開平４−８４８２６号公報（第３頁、第３―４図） Conventionally, with the inheritance of an exhaust chain that is connected to the feed chain and obliquely transports, the transport direction is refracted, so that the exhaust chamber is easily clogged or pulled out. Release the locking device that fixes the transport body against the evacuation guide rod held on the floor and open it upward with the reinforced evacuation frame as a pivot point. The transport body rises with the support frame. Thus, there is a structure in which the distance from the evacuation guide rod is widened and the maintenance can be easily performed (for example, see Patent Document 1). However, the frame on which the carrier is mounted passes through the upper part of the waste chain, the rotation center is higher than the drive case, and the distance between the handling cylinder shaft and the input shaft fluctuates. It is a rotation conveyance body with operation which removes.
Japanese Patent Laid-Open No. 4-84826 (Page 3, Fig. 3-4)

排藁チェンを上下回動させる従来技術は、搬送体と並行にした排稈フレームを前記排藁チェンの上方に架設し、回動支点を搬送体から離反した機体内側に設けたフレーム構造にしたものであり、回動操作によって扱胴軸と入力軸の軸間が変動し、回動操作毎に機体内に装備した駆動ベルトを脱着する等の手間が掛かり、重量物の搬送装置を持上げる労力が増加する問題がある。   The conventional technology for rotating the waste chain up and down has a frame structure in which a waste frame parallel to the transport body is installed above the waste chain, and a rotation fulcrum is provided inside the machine body away from the transport body. Because the rotation operation fluctuates between the handling cylinder shaft and the input shaft, it takes time and effort to detach and attach the drive belt installed in the body for each rotation operation, and lifts the heavy material conveyance device. There is a problem that labor is increased.

このような問題点を解決するために、搬送体を上下に回動させても駆動ベルトの軸間が変動しない回動中心線を設定し、該駆動ベルトを装着した状態のままで詰まりの除去や整備点検が行え、しかも、持上げる回動労力が軽減するように搬送体の回動半径を短縮させた排藁搬送装置の提供を目的とするものである。   In order to solve such problems, a rotation center line that does not fluctuate between the axes of the drive belt even when the transport body is rotated up and down is set, and clogging is removed with the drive belt attached. It is an object of the present invention to provide a waste transporting apparatus that can perform maintenance and inspection and that has a shortened turning radius of the transport body so as to reduce the lifting effort to lift.

扱胴軸から動力を受動する搬送体を上下回動可能にした排藁搬送装置において、該搬送体を駆動する入力プーリの中央部に向けて前記搬送体の回動中心線を延設させるとともに穂先を搬送する搬送帯側を支点にし、回動可能に支持する支持部材を排稈フレームから吊設して回動中心線に連結したことにより、搬送体の回動半径が短縮されて排藁室内で該搬送体を回動可能に支持する支点構造にしたものである。   In a waste transporting device in which a transporting body that passively drives power from a handling cylinder shaft can be turned up and down, a rotation center line of the transporting body is extended toward a central portion of an input pulley that drives the transporting body. A support member that supports the pivot is supported from the exclusion frame and connected to the rotation center line, and the rotation radius of the conveyance body is shortened. This is a fulcrum structure that rotatably supports the carrier in the room.

入力プーリ２の中央部Ｘに向けて延長した回動中心線Ｐを搬送体１の回動支点にしたので、回動操作にともなう扱胴軸７と入力軸８の軸間に変動が生じず、搬送体１の回動角度１０だけ該入力プーリ２が傾斜した状態で駆動ベルト１１の張力変化が最少限にとどまり、前記搬送体１の回動操作毎に駆動ベルト１１を脱着する手間が解消された。又、穂先を搬送する搬送帯３５側を支点にして搬送体１を回動可能にしたので、搬送障害を生じ易い排藁チェン１４側の挟扼力を主に開放し、その支点構造も簡素化された。このような支点構造を固定した排稈フレーム５から支持部材を吊設して回動中心線Ｐに連結させ、回動支点を入力プーリ２の軸芯まで降下した位置に設定したものであり、その回動半径を排藁チェン１４と回動中心線Ｐとの間隔に短縮したために、前記搬送体１が排藁室４０内で回動可能になり、排稈フレーム５を固設したまま回動操作が行え構造の簡素化と、搬送装置を持上げる操作力を軽減させる効果がある。   Since the rotation center line P extending toward the central portion X of the input pulley 2 is used as the rotation fulcrum of the transport body 1, no fluctuation occurs between the handling cylinder shaft 7 and the input shaft 8 due to the rotation operation. In the state where the input pulley 2 is inclined by the rotation angle 10 of the transport body 1, the change in the tension of the drive belt 11 is kept to the minimum, and the trouble of removing the drive belt 11 every time the transport body 1 is rotated is eliminated. It was done. In addition, since the transport body 1 can be rotated with the transport belt 35 side for transporting the tip as a fulcrum, the pinching force on the side of the reject chain 14 which is likely to cause a transport failure is mainly released, and the fulcrum structure is also simple. It became. A support member is suspended from the evacuation frame 5 with such a fulcrum structure fixed and connected to the rotation center line P, and the rotation fulcrum is set at a position lowered to the axis of the input pulley 2. Since the turning radius is shortened to the interval between the waste chain 14 and the rotational center line P, the transport body 1 can be turned in the waste room 40 and can be rotated with the waste frame 5 fixed. It is possible to perform a moving operation, simplifying the structure, and reducing the operation force for lifting the transfer device.

A handling cylinder 26 in which handling teeth 32 are implanted in the handling chamber 25 is rotatably mounted, and the harvested cereal meal is conveyed by the feed chain 23 arranged in parallel. The carrier 1 is formed by a waste chain 14 that obliquely transports the waste after the grain removal and a transport belt 35 provided on the tip side, and is discharged from the feed chain 23 on the start end side. , And a waste transporting device that supplies the cutter unit 37 mounted on the rear side of the machine body.

次に搬送装置を収設した排稈フレームの構成を説明すると、扱室２５の後壁３８に排稈フレーム５を連結して排藁室４０の上方にコの字型に配置させ、終端に立設する門形フレーム４１に螺着し、前記排稈フレーム５の対角部５５ａ、５５ｂに搬送体１を横断する支持パイプ４２ａ、４２ｂを架設したフレーム構造により、排藁室４０を形成したものである。   Next, the configuration of the evacuation frame in which the transfer device is accommodated will be described. The evacuation frame 5 is connected to the rear wall 38 of the handling chamber 25 and arranged in a U-shape above the evacuation chamber 40. The evacuation chamber 40 is formed by a frame structure in which the support pipes 42a and 42b that cross the carrier 1 are installed on the diagonal portions 55a and 55b of the evacuation frame 5 by being screwed to the standing portal frame 41. Is.

排稈フレームから支持した搬送装置の駆動構造を図４の搬送体を示す平面図と、始端側を示す図３の平面図を併用して説明すると、排藁チェン１４の駆動を扱胴軸７の軸端に固設した駆動プーリ４６から出力し、搬送体１に連結する駆動ケース６に装備した入力プーリ２に受動して、入力軸８と一対のベベルギヤ４７を介して前記排藁チェン１４の作用側が後方に移動する回転を付与するものであり、挟扼ガイド４８と穂部ガイド５０を前後に並設して排稈の穂部側と稈元側を挟扼しながら斜搬送するものである。又、非作用側の排藁チェン１４に噛合させたスプロケット５１によって、連結ケース５２を介して対向する搬送帯３５の始端側に再入力させ、前記排藁チェン１４と同方向に回転する排藁搬送装置である。   The drive structure of the transport device supported from the reject frame will be described with reference to the plan view showing the transport body in FIG. 4 and the plan view in FIG. 3 showing the start end side. Is output from a drive pulley 46 fixed to the shaft end of the shaft, and is passively input to the input pulley 2 mounted on the drive case 6 connected to the transport body 1 to pass through the input chain 8 and the pair of bevel gears 47 to the exhaust chain 14. Rotating movement side is added to the rear, and pinch guide 48 and head part guide 50 are juxtaposed in front and rear, and transported obliquely while pinching the head part side and the head side of the waste. It is. Further, the sprocket 51 meshed with the non-operating side exhaust chain 14 is re-inputted to the starting end side of the opposite conveying band 35 through the connection case 52 and is rotated in the same direction as the exhaust chain 14. It is a transport device.

本発明の要旨である搬送装置が上下動する回動中心線の設定について上記する図２、３、４図を併用して説明すると、回動支点を結んだ回動中心線Ｐを入力プーリ２の中央部Ｘに向けて延設させ、排藁搬送装置の上方に架設した排稈フレーム５から支持メタル３ａ、３ｂを吊設し、搬送帯３５側と該回動中心線Ｐが平面視と一致する位置を回動支点にしたことによって、搬送体１を矢印イの方向に回動させた場合に、駆動ケース６に内装した入力軸８と該扱胴軸７の軸間が変動しない構成になり、駆動ベルト１１の張力変化を最小限にとどめたものである。   The setting of the rotation center line in which the conveying device moves up and down, which is the gist of the present invention, will be described with reference to FIGS. 2, 3 and 4 described above. The rotation center line P connecting the rotation fulcrums is defined as the input pulley 2. The support metals 3a and 3b are suspended from a waste frame 5 that extends toward the central portion X of the waste transport device, and the transport belt 35 side and the rotation center line P are in plan view. A configuration in which the shaft between the input shaft 8 and the barrel shaft 7 provided in the drive case 6 does not change when the transport body 1 is rotated in the direction of the arrow a by using the coincident position as a rotation fulcrum. Thus, the tension change of the drive belt 11 is minimized.

このような回動中心線Ｐを設定したことによって、図５の前方支持メタルの正面図に鎖線で示す如く搬送体１の回動操作を行うと、入力プーリ２が中央部Ｘを中心に回転角度１０に相当する分傾斜するが、前述したように軸間が変動しないために、前記入力プーリ２に巻き掛けた駆動ベルト１１の張力変化が最小限にとどまり、回動操作毎に脱穀部Ａ内で行う前記駆動ベルト１１の脱着手間が解消できる構成にしてある。   By setting such a rotation center line P, when the carrier 1 is rotated as shown by the chain line in the front view of the front support metal in FIG. Although it is inclined by an amount corresponding to the angle 10, as described above, there is no fluctuation between the shafts. It is configured to eliminate the trouble of attaching and detaching the drive belt 11 performed inside.

次に回動支点の支持構造とその特徴を説明すると、回動する搬送体１を排藁チェン１４に搬送帯３５を並設した構成にし、穂先を搬送する前記搬送帯３５側を支点にして搬送体１を回動可能にしたものであって、固定した排稈フレーム５から支持アーム４を排稈フレーム５から吊設して回動中心線Ｐに連結させ、支点位置を入力プーリ２の軸芯まで降下させて該回動中心線Ｐ上に回動支点を設定し、その回動半径を前記排藁チェン１４と回動中心線Ｐとの間隔に短縮させたことによって、前記搬送体１が排藁室４０内で回動可能になり、排稈フレーム５を固設したままで回動操作が行える構成にしたものである。   Next, a description will be given of the support structure of the pivoting fulcrum and its characteristics. The rotating transport body 1 is configured by arranging the transport band 35 side by side on the rejection chain 14, and the transport band 35 side for transporting the tip is used as a fulcrum. The carrier 1 is made rotatable, and a support arm 4 is hung from the fixed evacuation frame 5 and connected to the rotation center line P, and the fulcrum position is set to the input pulley 2. By lowering to the shaft center, a rotation fulcrum is set on the rotation center line P, and the rotation radius is shortened to the interval between the waste chain 14 and the rotation center line P. 1 is configured to be able to rotate in the evacuation chamber 40, and to perform a rotation operation with the evacuation frame 5 fixed.

図３の拡大平面図に示す前方支持メタル３ａの配置は、回動中心線Ｐが通過する駆動ケース６の位置に支点軸１２ａを一体的に装着し、前支持パイプ４２ａから吊設した前支持アーム４ａに前記前方支持メタル３ａを設け、該支点軸１２ａと係合させた回動自在の連結構造にし、フィードチェン２３から排稈を受継ぐ排藁チェン１４の始端側強度を保持し、剛性の高い前記駆動ケース６を介在させた構成によって、詰まり等の搬送異状による変形や破損防止をしたものである。   The arrangement of the front support metal 3a shown in the enlarged plan view of FIG. 3 is a front support in which a fulcrum shaft 12a is integrally mounted at the position of the drive case 6 through which the rotation center line P passes and is suspended from the front support pipe 42a. The arm 4a is provided with the front support metal 3a, and is connected to the fulcrum shaft 12a so as to be rotatable. The rigidity of the start end side of the waste chain 14 that inherits the waste from the feed chain 23 is maintained and is rigid. The structure with the high drive case 6 interposed prevents deformation and breakage due to conveyance abnormalities such as clogging.

図５と図６は支持メタルの前方と後方を示す正面図であって、図１の脱穀部の後方平面図を併用して排稈フレームから吊設した搬送体の支持構造を説明すると、前述したように脱穀部Ａの後壁３８からコの字型に排稈フレーム５を配置し、入力プーリ２側の角部５５ａ上に前支持パイプ４２ａを設け、対向する角部５５ｂにも同様の後支持パイプ４２ｂを対設し、搬送体１の上方を横断する前記支持パイプ４２と回動中心線Ｐが平面視で交叉する位置に向け、支持アーム４ａ、４ｂを排稈フレームから吊設して排藁チェン１４と並行する支持メタル３ａ、３ｂを設けたものである。これを中心にして搬送体１を回動角度１０に開放をさせた際に、入力プーリ２が図５の鎖線で示す中央部Ｘを軸芯に変位するようにした支持構造にしてある。   FIG. 5 and FIG. 6 are front views showing the front and rear of the support metal, and the support structure of the carrier suspended from the waste frame using the rear plan view of the threshing portion of FIG. As described above, the waste frame 5 is disposed in a U-shape from the rear wall 38 of the threshing portion A, the front support pipe 42a is provided on the corner portion 55a on the input pulley 2 side, and the same is applied to the opposite corner portion 55b. A pair of rear support pipes 42b are provided, and the support arms 4a and 4b are suspended from the evacuation frame so that the support pipes 42 crossing over the transport body 1 and the rotation center line P cross each other in plan view. The support metals 3a and 3b are provided in parallel with the waste chain 14. The support structure is configured such that when the transport body 1 is opened at the rotation angle 10 around this, the input pulley 2 is displaced with the central portion X indicated by the chain line in FIG.

一方後方支持メタル３ｂは、排藁チェン台６０と搬送帯ケース１３を連結する補強板５８を後方に設け、その近傍で搬送帯３５側と回動中心線Ｐを平面視で一致させた位置を回動支点にし、該搬送帯ケース１３の中央付近に装着溝５６を設けてケース周辺の強度を高め、前記回動中心線Ｐと同方向に取付座５７を溶着し、前記後方支持メタル３ｂを挟持した状態で後支点軸１２ｂを嵌入させ、該搬送帯３５側を回動支点にした排藁搬送装置にしてある。尚、図５に示した挟扼ガイド４８は床面７３の下方から排藁チェン１４側にバネ７５で付勢したものであり、挟扼する排稈量の増減に伴い出退する構成にしてある。   On the other hand, the rear support metal 3b is provided with a reinforcing plate 58 for connecting the waste chain base 60 and the transport band case 13 at the rear, and in the vicinity thereof, the position where the transport band 35 side and the rotation center line P coincide with each other in plan view. A mounting groove 56 is provided near the center of the transport belt case 13 to increase the strength around the case, and a mounting seat 57 is welded in the same direction as the rotation center line P. The rear support metal 3b is In this state, the rear fulcrum shaft 12b is fitted in the sandwiched state, and the evacuation conveyance device has the conveyance band 35 side as a rotation fulcrum. The pinching guide 48 shown in FIG. 5 is urged by a spring 75 from below the floor surface 73 toward the waste chain 14 side, and is configured to move out and back as the amount of waste trapped is increased or decreased. is there.

図７は要部を断面した調節レバーの側面図であって、図３の始端側を拡大した平面図に図４の平面図を併用して排稈の搬送状態から開放状態にする回動操作を説明すると、排藁チェン台６０と搬送帯ケース１３の間を接続する連結ケース５２を搬送体１の前側に、補強板５８を後方に装着して一体化した搬送体１を形成し、該排藁チェン台６０の外面にレバー受６１を設けて屈曲した調節レバー６２の垂直部６３を嵌入させ、その軸端に抜け止ピン６５を設けて左右の回動を可能にしたレバー構造にしてある。   FIG. 7 is a side view of the adjusting lever with a cross-sectional view of the main part, and a turning operation for bringing the waste end from the transported state into the open state by combining the plan view of FIG. 4 with the enlarged plan view of the starting end side of FIG. , The connecting case 52 for connecting the waste chain base 60 and the transport belt case 13 is attached to the front side of the transport body 1 and the reinforcing plate 58 is attached to the rear side to form the transport body 1 integrated, The lever portion 61 is provided on the outer surface of the reject chain base 60, and the vertical portion 63 of the adjustment lever 62 bent is fitted, and the retaining pin 65 is provided at the end of the shaft so that the lever can be turned left and right. is there.

この調節レバー６２を案内する調節板６６を前支持パイプ４２ａから垂設し、回動中心線Ｐに対向したガイド溝６７を穿ち、その両端に下限孔６８と上限孔７０を鉤形に設けた形状を鎖線で図示する投影図に示してあり、該調節レバー６２が下限孔６８に嵌着した位置において挟扼ガイド４８に排藁チェン１４のプレートが嵌り込んだ搬送状態になり、矢印ロ方向のレバー操作によって上限孔７０の位置に移動させて搬送体１が挟扼力を失う開放状態を保持するものである。   An adjustment plate 66 for guiding the adjustment lever 62 is suspended from the front support pipe 42a, a guide groove 67 facing the rotation center line P is formed, and a lower limit hole 68 and an upper limit hole 70 are provided in a bowl shape at both ends thereof. The shape is shown in a projection diagram shown by a chain line, and at the position where the adjustment lever 62 is fitted in the lower limit hole 68, the conveying guide is fitted with the plate of the reject chain 14 fitted in the clamping guide 48, and the direction of arrow B The lever 1 is moved to the position of the upper limit hole 70 to maintain the opened state in which the carrier 1 loses the pinching force.

このような開放状態にした搬送体１の回動位置で搬送帯３５側の移動を少なくし、排藁チェン１４側の開放距離を大きくして排稈層の厚い稈元側の開放状態を顕著にするために、前記排藁チェン１４から回動中心線Ｐまでの間隔を回動半径にし、搬送帯３５側と一致した回動支点の位置になるように該回動半径が短縮され、回動操作時の持上げ力も軽減したものである。尚、このようなレバー装置を前記搬送体１の前後に設置すれば搬送装置が排稈フレーム５に複数箇所で接続でき、一層強固な連結構造にすることができる。   The movement of the transport belt 35 in the opened position of the transport body 1 in such an open state is reduced, the open distance on the waste chain 14 side is increased, and the open state on the base side where the waste layer is thick is remarkable. In order to achieve this, the distance from the waste chain 14 to the rotation center line P is set to the rotation radius, and the rotation radius is shortened so that the rotation fulcrum coincides with the conveyance band 35 side. The lifting force during dynamic operation is also reduced. In addition, if such a lever apparatus is installed before and behind the said conveyance body 1, a conveyance apparatus can be connected to the rejection frame 5 in multiple places, and it can be set as a still stronger connection structure.

上記したように入力プーリ２の中央部Ｘに向けて延長した回動中心線Ｐを搬送体１の回動支点にしたので、回動操作にともなう扱胴軸７と入力軸８の軸間は変動せず、搬送体１の回動角度１０だけ該入力プーリ２が傾斜した状態で駆動ベルト１１の張力変化が最少限にとどまり、前記搬送体１の回動操作毎に駆動ベルト１１を脱着する手間が解消された。又、穂先を搬送する搬送帯３５側を支点にして搬送体１を回動可能にしたので、排藁チェン１４側の回動幅を搬送帯３５側よりも大きく開放する支点構造になり、その支持部材を排稈フレーム５から吊設して支点位置を入力プーリ２の軸芯まで降下させ、回動中心線Ｐと該排藁チェン１４との間隔を回動半径に短縮したので、前記搬送体１が排藁室４０内で回動可能になり、排稈フレーム５を固設したままの回動操作が行える簡素化した支点構造になるとともに、搬送装置を持上げる調節レバー６２の操作力を軽減させたものである。   As described above, the rotation center line P extended toward the central portion X of the input pulley 2 is used as the rotation fulcrum of the transport body 1, so that there is a gap between the handling cylinder shaft 7 and the input shaft 8 associated with the rotation operation. The change in the tension of the drive belt 11 is kept to a minimum with the input pulley 2 tilted by the rotation angle 10 of the transport body 1 without fluctuation, and the drive belt 11 is detached and attached every time the transport body 1 is rotated. The trouble has been eliminated. In addition, since the transport body 1 can be rotated with the transport band 35 side that transports the tip as a fulcrum, the fulcrum structure that opens the rotation width on the waste chain 14 side larger than the transport band 35 side, Since the support member is suspended from the reject frame 5 and the fulcrum position is lowered to the axis of the input pulley 2, the distance between the rotation center line P and the reject chain 14 is shortened to the rotation radius. The body 1 can be rotated in the evacuation chamber 40, and a simplified fulcrum structure that can be rotated while the evacuation frame 5 is fixed is provided. Is reduced.
