The chain is provided in the order of the chain 6d and the supply device 6e, and is configured to be conveyed while successively inheriting grain culms, passed to the feed chain 12, and supplied to the threshing device 3.

そして、刈取サイドカバ−７は、図６の仮想線で示すように、上記した刈取前処理装置１３の側部を覆うカバ−であって、安全機能と防塵機能と美観を向上するために設けているが、前縁を機体の側部に位置する穀稈引起し装置４の前側（側面視）に沿わせ、底縁を下側の刈取機枠１６の下縁に沿わせ、後縁を引起し支持フレ−ム２０の後方位置まで延長し、上縁を前記変速装置２３の側部上方を側面から覆う範囲に設けて構成している。 The cutting side cover 7 is a cover for covering the side of the above-mentioned cutting pretreatment device 13 as shown by the phantom line in FIG. 6, and is provided for improving the safety function, the dustproof function and the aesthetic appearance. However, the leading edge is aligned with the front side (side view) of the grain stalk raising device 4 located on the side of the body, the bottom edge is aligned with the lower edge of the lower mower frame 16, and the rear edge is raised. The transmission frame 23 is extended to the rear position of the support frame 20, and the upper edge is provided in a range that covers the upper side of the transmission 23 from the side.

つぎに、防塵カバ−８は、前記穀稈引起し装置４の上方位置から脱穀装置３の穀稈供給口２に至る間において、上側から前述の穀稈搬送装置６を覆うために、前部カバ−８ａと後部カバ−８ｂとの２つに分割して構成している。 Next, the dust cover 8 is provided with a front part to cover the above-mentioned grain culm conveying device 6 from above from the upper position of the grain culm raising device 4 to the grain culm supply port 2 of the threshing device 3. The cover is divided into two parts, a cover 8a and a rear cover 8b.

そこで、防塵カバ−８を支持する関連部材を、予め説明すると、まず、前後連結フレ−ム２５は、前端部を伝動ケ−ス２１（穀稈引起し装置４の上方位置）に連結固着して、図２及び図６に示すように、後方に延長して後端部を前記刈取主フレ−ム１５の基部に連結して刈取機枠１６を強固に補強する構成としている。そして、左支持杆２６は、前部を前記引起し支持フレ−ム２０の中間部に連結して後方上方に延長して後部に前記供給装置６ｅの挾持杆２７を取り付けて構成している。そして、横連結杆２８は、穀稈搬送装置６の中間部上方において∩型にして、右端部を前記前後連結フレ−ム２５に固着連結し、左端部を上記左支持杆２６の中端部に固着連結して全体として刈取機枠１６を補強する構成としている。なお、本明細書における左右は、走行車体１の前進方向に向かって見た状態を基準とする。 Therefore, the related members supporting the dust cover 8 will be described in advance. First, the front-rear connection frame 25 is connected and fixed at the front end to the transmission case 21 (upper position of the grain stem raising device 4). As shown in FIGS. 2 and 6, the rear end is connected to the base of the mowing main frame 15 so as to be extended rearward, so that the mower frame 16 is strongly reinforced. The left support rod 26 is constructed such that the front part is raised and connected to the middle part of the support frame 20, extended upward and rearward, and the holding rod 27 of the supply device 6e is attached to the rear part. The horizontal connecting rod 28 is shaped like a triangle above the middle part of the grain culm conveying device 6, and the right end is fixedly connected to the front and rear connecting frame 25, and the left end is the middle end of the left supporting rod 26. To the reaper frame 16 as a whole. Note that the left and right in this specification are based on the state of the traveling vehicle body 1 as viewed in the forward direction.

つぎに、前部カバ−８ａは、図７に示すように、その前縁を穀稈引起し装置４の上方において横向きに配置されている前記伝動ケ−ス２１の上にある引起しカバ−２４の上側に重ね合わせて連結固着し、その前縁部分で、左側を変速装置２３を覆う位置まで横方向に延長し、右側を上記した前後連結フレ−ム２５を覆う位置まで右の方に延長して設け、更に、穀稈搬送装置６の上方に沿わせて後方へ延長して配置している。そして、前部カバ−８ａは、その後部を前述の横連結杆２８に連結支持している。 Next, as shown in FIG. 7, the front cover 8a has its front edge raised above the transmission case 21 which is disposed laterally above the grain stalk raising device 4. At the front edge portion, the left side extends laterally to a position covering the transmission 23, and the right side extends rightward to a position covering the front-rear connection frame 25. It is provided so as to be extended and further extended rearward along the upper part of the grain stalk transport device 6. The front cover 8a has its rear portion connected to and supported by the horizontal connecting rod 28 described above.

つぎに、後部カバ−８ｂは、前端を前部カバ−８ａの後部上方に重ねて位置させ、後端を脱穀装置３の穀稈供給口２の上方まで延長して設け、上面と横側に垂れ下がった側壁９から形成して穀稈搬送装置６を上方から覆う構成としている。そして、後部カバ−８ｂは、左右の内側に前後方向に沿わせて固着している案内レ−ル３０、３０’を、前記横連結杆２８から左右両方の外側へ対称状に突出させて軸架しているロ−ラ３１、３１’に嵌合して支持して設け、更に、後部には回動腕３２を取り付けて前後摺動自由に支持して構成している。 Next, the rear cover 8b is provided such that the front end is positioned above the rear part of the front cover 8a so as to overlap with the rear cover 8a, and the rear end is extended to above the grain culm supply port 2 of the threshing device 3 and provided on the upper surface and the side. It is configured to be formed from the hanging side wall 9 and to cover the grain culm conveying device 6 from above. The rear cover 8b is formed by projecting the guide rails 30 and 30 'fixed to the left and right inner sides along the front-rear direction symmetrically outward from the horizontal connecting rod 28 to both the left and right sides. It is fitted and supported on the rollers 31 and 31 'mounted thereon, and furthermore, a rotating arm 32 is attached to the rear portion so as to be freely slidable back and forth.

そして、案内レ−ル３０、３０’は、側面視において図９に示すように、前部と後部とを高くして中間部から後部寄りの位置を若干下げた形状に形成すると、後部カバ−８ｂを、前部カバ−８ａの上面に沿わせて摺動することができる。 When the guide rails 30 and 30 'are formed in a shape in which the front and rear portions are raised and the position closer to the rear portion is slightly lowered from the middle portion as shown in FIG. 8b can be slid along the upper surface of the front cover 8a.

そして、回動腕３２は、基部を支持台１４上の前記前後連結フレ−ム２５の連結部分と一体的に枢着して上方に延長した基部部材３２ａと、その基部部材３２ａの上部に形成した連結部３２ｂを介して着脱自由に連結した上側の支持部材３２ｃとの２部材で構成し、後部カバ−８ｂを前後に摺動自由に支持している。そして、回動腕３２は、後方で待機するとき（後部カバ−８ｂが閉まった位置）の位置と、前方側に回動したとき（後部カバ−８ｂを前側に移動して開放した位置）の位置とのいずれにおいても、連結部３２ｂが穀稈供給口２と前記穂先搬送ラグ６ｃを収納している穂先搬送ケ−ス３３の高さ位置よりも高い位置にある構成としている。 The rotating arm 32 is formed on a base member 32a extending upward by pivotally connecting the base portion integrally with the connecting portion of the front-rear connecting frame 25 on the support base 14, and formed on an upper portion of the base member 32a. The upper cover member 32c is detachably connected via the connecting portion 32b, and supports the rear cover 8b so as to be slidable back and forth. The rotating arm 32 is in a position where it stands by behind (position where the rear cover 8b is closed) and a position where it pivots forward (position where the rear cover 8b is moved forward and opened). In any of the positions, the connecting portion 32b is located at a position higher than the height position of the spike feeding case 33 that stores the grain stem supply port 2 and the spike conveying lug 6c.

したがって、後部カバ−８ｂは、空間部分に位置することになり、比較的簡単に着脱することが可能になるものである。 Therefore, the rear cover 8b is located in the space, and can be relatively easily attached and detached.

そして、後部カバ−８ｂは、横連結杆２８に設けている前部クランプ３４と脱穀装置３側に設けている後部クランプ３４’とに、前記回動腕３２の上部に設けている前係止具３５と後係止具３５’とを係脱自由に係止して開放位置と閉鎖位置とをロックできる構成としている。 The rear cover 8b is connected to a front clamp 34 provided on the horizontal connecting rod 28 and a rear clamp 34 'provided on the threshing device 3 side by front locking provided on the upper part of the rotating arm 32. The tool 35 and the rear locking tool 35 'are configured to be freely engaged and disengaged so that the open position and the closed position can be locked.

そして、後部カバ−８ｂは、図１及び図２に示すように、その後端縁と脱穀装置３の前端縁との間隙に沿わせて適宜幅のスペ−サ３６を用意して着脱自由に取り付けることによって、汎用性を高めることができる。例えば、防塵カバ−８は、３条型用のものを製作しておいて、それより大型のコンバイン（４、５条型）に組み付けるとき、間隙をスペ−サ３６でふさぐことにより可能にし、全体として大幅なコストダウンを図ることができる。 As shown in FIGS. 1 and 2, the rear cover 8b is provided with a spacer 36 having an appropriate width along the gap between the rear edge and the front edge of the threshing device 3, and is detachably attached. Thereby, versatility can be improved. For example, the dust-proof cover 8 is made for a three-row type, and when assembling to a larger combine (4, 5-row type), the gap can be closed by a spacer 36. Significant cost reduction can be achieved as a whole.

そして、防塵カバ−８は、図１０に示すノンキャビンタイプのコンバイン用と図１１に示すキャビンタイプのコンバイン用との２種類を構成している。すなわち、一方（図１０）の防塵カバ−８は、中央位置に隆起部４０を形成して、その隆起部４０の前部に前照灯４１を取り付けて前方を照明できる構成として、図３及び図４に示すように、キャビンを有しないコンバイン専用としている。他方（図１１）のキャビンタイプの防塵カバ−８は、隆起部４０に相当する隆起形状を無くして平面部４２にして前照灯４１を設けない構成にして、図５に示すように、キャビン４３を有するコンバイン専用にしている。この場合は、防塵カバ−８は、キャビン４３の前面上部に前照灯４４が装着されているから、前照灯４１は不要となる。 The dust cover 8 has two types, a non-cabin type combiner shown in FIG. 10 and a cabin type combiner shown in FIG. That is, one of the dustproof covers 8 (FIG. 10) has a raised portion 40 formed at a central position, and a headlight 41 is attached to a front portion of the raised portion 40 to illuminate the front. As shown in FIG. 4, it is dedicated to a combine without a cabin. On the other hand, the cabin type dustproof cover 8 (FIG. 11) has a configuration in which the raised shape corresponding to the raised portion 40 is eliminated and the flat portion 42 is not provided with the headlight 41, as shown in FIG. 43 is dedicated to the combine. In this case, since the dust cover 8 has the headlight 44 mounted on the upper front surface of the cabin 43, the headlight 41 becomes unnecessary.

そして、隆起部４０は、図１０に示すように、前進方向の左側に片寄せて設け右側にフラット面４５を形成して、操縦席４６からの前方視界を確保する構成としている。なお、フラット面４５は、透明素材を使用すると、これを透視して穀稈の搬送状態や前方低部を確認することができて便利である。 As shown in FIG. 10, the raised portion 40 is provided so as to be offset toward the left side in the forward direction and forms a flat surface 45 on the right side so as to secure a front view from the cockpit 46. In addition, if a transparent material is used for the flat surface 45, it is convenient to see through the transparent material to check the transport state of the grain stem and the lower front portion.

つぎに、移動通路１０は、図１に示すように、前記前部カバ−８ａの前後方向に沿う側縁イと前記刈取サイドカバ−７の内側縁ロとの間に間隔を設けて構成して、前記後部カバ−８ｂの側壁９が自由に通過できるように形成されている。したがって、後部カバ−８ｂは、後部の回動腕３２に支持され、更に、案内レ−ル３０、３０’がロ−ラ３１、３１’に支持されて案内されながら、前部カバ−８ｂの上側に沿って前方に重なりながら摺動できる。なお、４７は把手を示す。 Next, as shown in FIG. 1, the moving passage 10 is formed by providing an interval between a side edge a along the front-rear direction of the front cover 8a and an inner edge B of the cutting side cover 7. The side wall 9 of the rear cover 8b is formed so that it can pass freely. Therefore, the rear cover 8b is supported by the rear rotating arm 32, and the guide rails 30, 30 'are supported and guided by the rollers 31, 31'. It can slide while overlapping forward along the upper side. 47 indicates a handle.

そして、前述した変速装置２３は、図１２に示すように、中間部をケ−ス４８の表面に枢着した作動レバ−４９の上部に操作ロット５０を枢着して連結し、下部に図示しないシフタ−を連結している。そして、操作ロット５０は、引起しカバ−２４の上方に沿わせ、前部カバ−８ａの内部を通して右方向に延長し、前後連結フレ−ム２５に設けた支持具５１に操作自由に支持している。そして、握り部５２は、上記した操作ロット５０の支持位置から若干外側部を上方に折り曲げて取り付け、操縦席４６から手を伸ばして握り、穀稈引起し装置４の引起しラグ１９の引起し速度を変速操作できる構成としている。 In the transmission 23, as shown in FIG. 12, an operation lot 50 is pivotally connected to an upper portion of an operation lever 49 having an intermediate portion pivotally connected to the surface of the case 48, and is shown in the lower portion. No shifters are connected. The operation lot 50 extends rightward through the inside of the front cover 8a along the upper side of the raising cover 24, and is operably supported by a support member 51 provided on the front and rear connecting frame 25. ing. Then, the grip portion 52 is attached by bending the outer portion slightly upward from the support position of the operation lot 50 described above, reaching out from the cockpit 46 and gripping, raising the raising lug 19 of the grain stem raising device 4. The speed can be changed.

つぎにその作用について説明する。 Next, the operation will be described.

まず、防塵カバ−８は、後部カバ−８ｂを、図１及び図２の実線で示す位置に閉じた状態にして、後係止具３５’を後部クランプ３４’に係合してロックし、穀稈搬送装置６を覆って防塵機能が発揮できるように準備する。そして、エンジンを始動して機体の回転各部に伝動しながら走行車体１を前進させて作業を開始する。 First, the dust cover 8 closes the rear cover 8b to the position shown by the solid line in FIGS. 1 and 2 and engages and locks the rear locking member 35 'with the rear clamp 34'. A preparation is made to cover the grain stalk transport device 6 so that the dustproof function can be exhibited. Then, the engine is started and the traveling vehicle body 1 is moved forward while being transmitted to the rotating parts of the body to start work.

すると、圃場の穀稈は、前部の分草杆１７によって下部から分草作用を受けた後、上方に引起し回動を続けている引起しラグ１９の作用を受けて、倒伏状態から順次直立状態に引き起こされ、株元部分が掻込装置６ａに達して刈取装置５側に掻き込まれる。そして、穀稈は、刈取装置５によって刈り取られ、株元が株元搬送チエン６ｂに挾持され、穂先側が穂先搬送ラグ６ｃに係合されて順次上方に搬送される。そして、穀稈は、扱ぎ深さ調節チエン６ｄから供給装置６ｅに受け継がれてフィ−ドチエン１２の始端部に受け継がれて脱穀装置３の穀稈供給口２に供給される。このようにして、脱穀装置に供給された穀稈は、株元がフィ−ドチエン１２に挾持されて搬送されながら穂先部が脱穀装置３に挿入されて脱穀作用を受け、選別された穀粒がグレンタンクに搬送されて貯溜される。 Then, the culm in the field is subjected to weeding action from the lower part by the weeding rod 17 in the front part, and then is acted on by the elevating lugs 19 that are elevating upward and continuing to rotate. It is caused to stand upright, and the root portion of the stock reaches the scraping device 6a and is scraped to the reaping device 5 side. Then, the grain stalk is cut off by the cutting device 5, the stock is clamped by the stock transfer chain 6b, and the spike side is engaged with the spike transfer lug 6c to be sequentially conveyed upward. The grain culm is passed from the handling depth adjusting chain 6d to the feeding device 6e, is passed to the starting end of the feed chain 12, and is supplied to the grain culm supply port 2 of the threshing device 3. In this way, the grain culm supplied to the threshing device is subjected to threshing by inserting the head portion into the threshing device 3 while the stock is held between the feedstocks 12 and conveyed, and the selected grains are subjected to threshing. It is transported to the Glen tank and stored.

このような一連の刈取脱穀作業中において、防塵カバ−８は、穀稈引起し装置４の上部位置から、掻込装置６ａ、その後方の株元搬送チエン６ｂと穂先搬送ラグ６ｃ、更に、その後方位置の扱ぎ深さ調節チエン６ｄと供給装置６ｅを覆っているから、穀稈の搬送作用にともなって発生した塵埃を直接外部に飛散するのを防止してできるだけ外気を塵埃で汚さないように防塵しながら作業を行うことが出来る。 During such a series of cutting and threshing operations, the dustproof cover 8 is moved from the upper position of the grain stalk raising device 4 to the scraping device 6a, the stock transport chain 6b and the spike transport lug 6c at the rear thereof, and further thereafter. Since it covers the handling depth adjusting chain 6d and the supply device 6e at one side, the dust generated due to the conveying action of the grain stalk is prevented from being directly scattered to the outside, and the outside air is not polluted with dust as much as possible. Work can be performed while preventing dust.

そして、防塵カバ−８は、図１０に示すように、隆起部４０を進行方向の左側に片寄せてその右側にフラット面４５を形成しているから、操縦席４６からの前方視界が充分に確保でき、分草状態や引起し状態を監視しながら作業を行うことができる利点がある。なお、透明素材を使用してフラット面４５に構成すれば、透視できるから穀稈の搬送状態や前方低部を確認できてより便利である。 As shown in FIG. 10, the dust cover 8 has the raised portion 40 shifted to the left in the traveling direction and the flat surface 45 formed on the right side, so that the front view from the cockpit 46 is sufficient. There is an advantage that the work can be performed while monitoring the weeding state and the raising state. In addition, if the flat surface 45 is formed using a transparent material, the state of transportation of the grain stalk and the lower front portion can be checked because it can be seen through, which is more convenient.

更に、本発明の実施例は、図１及び図２に示すように、後部カバ−８ｂの後端縁と脱穀装置３の前端縁との間に、隙間ができたとき（例えば、３条型用のものを製作しておいて、それを４、５条型に転用して組み付ける等）、適宜幅のスペ−サ３６を用意してつぶす方策を講じているから、防塵カバ−８の汎用性を高め、大幅なコストダウンを図ることができた。そして、防塵カバ−８は、支持する各部材を、別に構成しないで刈取機枠１６を構成している前後連結フレ−ム２５や横連結杆２８を利用しているから、安価に製作できると共に、強固で安定良く支持され、円滑にスライドできる。 Further, as shown in FIGS. 1 and 2, the embodiment of the present invention is applicable when a gap is formed between the rear edge of the rear cover 8 b and the front edge of the threshing device 3 (for example, a three-row type). For example, it is necessary to manufacture a product for use, and divert it to a 4- or 5-type assembly before assembling it.) And improved cost performance. Since the dust cover 8 uses the front and rear connection frames 25 and the horizontal connection rods 28 that constitute the reaper frame 16 without separately configuring each supporting member, the dust cover 8 can be manufactured at low cost. Strong, stable and supported, and can slide smoothly.

そして、後部カバ−８ｂは、実施例のように、回動腕３２の連結部３２ｂを穀稈供給口２と前記穂先搬送ラグ６ｃを収納している穂先搬送ケ−ス３３の高さよりも高い空間部のある位置に構成しているから、いずれの位置にあっても、比較的簡単に着脱操作ができる特徴がある。そして、後部カバ−８ｂは、前後係止具３５、３５’を有する回動腕３２と、前後連結フレ−ム２５及びと前部、後部クランプ３４、３４’を有する横連結杆２８との関係位置が、刈取前処理装置１３を上下昇降させても変化しないから、不用意にロックが離脱することがほとんどなく、常に、安全にロック状態を保持できる特徴も併せて有する。 And, as in the embodiment, the rear cover 8b connects the connecting portion 32b of the rotating arm 32 to a height higher than the height of the spike carrier case 33 accommodating the grain stalk supply port 2 and the spike carrier lug 6c. Since it is configured at a position where the space is present, there is a feature that the attachment / detachment operation can be performed relatively easily at any position. The rear cover 8b is connected to a rotating arm 32 having front and rear locking members 35 and 35 ', a front and rear connecting frame 25, and a horizontal connecting rod 28 having front and rear clamps 34 and 34'. Since the position does not change even if the mowing pre-processing device 13 is moved up and down, the lock hardly comes off carelessly, and has a feature that the locked state can always be maintained safely.

そして、穀稈引起し装置４は、実施例に示すように、操縦席４６から手を伸ばして比較的簡単に握り部５２を操作して、操作ロット５０、作動レバ−４９から図示しないシフタ−を介して変速装置２３を、穀稈の倒伏度合いに応じて変速操作して効果的な作業を行うことができると共に、操作ロット５０を、引起しカバ−２４の上方に沿わせ、前部カバ−８ａの内部を通して右方向に延長することにより、下方を通過する穀稈に支障を与えることなく、藁屑等がひっかかることもない実用的効果を有するものとなった。 Then, as shown in the embodiment, the grain stalk raising device 4 relatively easily operates the grip portion 52 by reaching out from the cockpit 46 to operate the operation lot 50 and the operation lever 49 from a shifter (not shown). , The speed of the transmission 23 can be changed according to the degree of lodging of the cereal stem to perform an effective operation, and the operation lot 50 can be raised over the cover 24 so that the front cover can be moved. By extending to the right through the inside of -8a, practical effects were obtained without hindrance to the grain stem passing below and without being trapped by straw chips and the like.

更に、防塵カバ−８は、実施例の場合、図７に示すように、前部カバ−８ａの前縁を穀稈引起し装置４の上方において、横向きに配置されている伝動ケ−ス２１の上にある引起しカバ−２４の上側に重ね合わせて連結固着し、その前縁部分の左側を変速装置２３を覆う位置まで横方向に延長し、右側を前後連結フレ−ム２５を覆う位置まで右の方に延長して設けているから、意匠上の美観を向上するものでありながら、この位置に配線されるハ−ネスを被覆することができ雨水等から保護できる特徴を有する。 Further, in the case of the embodiment, as shown in FIG. 7, the dust-proof cover 8 has a transmission case 21 which is disposed laterally above the grain stem raising device 4 with the front edge of the front cover 8a. The upper side of the raising cover 24 is connected and fixed, and the left side of the front edge portion is extended laterally to a position covering the transmission 23, and the right side covers the front and rear connecting frame 25. Since it extends to the right, it has the characteristic of improving the aesthetic appearance of the design while covering the harness wired at this position and protecting it from rainwater and the like.

つぎに、防塵カバ−８は、一連の穀稈搬送装置６のメンテナンスを行うときには、後部カバ−８ｂの把手４７を持って、図１及び図２の実線の位置から仮想線で示す前方位置に移動操作する。すると、後部カバ−８ｂは、回動腕３２が下部を支点として前方側に回動し、両側にあるロ−ラ３１、３１’によって左右の案内レ−ル３０、３０’が案内されて回動しながら、脱穀装置３の穀稈供給口２側から順次開放する。そのとき、後部カバ−８ｂは、左側の側壁９が、前部カバ−８ａの前後方向に沿う側縁イと刈取サイドカバ−７の内側縁ロとの間に形成している移動通路１０を前方側に通過して円滑に移動して、前部カバ−８ａの上側に重合する位置に達して穀稈搬送装置６を開放することが出来る。 Next, when performing a series of maintenance of the grain stalk transport device 6, the dustproof cover 8 holds the handle 47 of the rear cover 8b from the position indicated by the solid line in FIGS. Move operation. Then, the rear cover 8b is rotated by the rotating arm 32 rotating forward with the lower portion as a fulcrum, and the left and right guide rails 30, 30 'are guided by the rollers 31, 31' on both sides. While moving, the threshing device 3 is sequentially opened from the cereal stem supply port 2 side. At this time, the rear cover 8b has a moving path 10 formed by the left side wall 9 between a side edge a along the front-rear direction of the front cover 8a and an inner edge b of the cutting side cover 7 in a forward direction. Then, the stalk conveying device 6 can be opened by reaching the position where it passes over the side and smoothly moves over the front cover 8a.

以上のように操作して防塵カバ−８の後部カバ−８ｂを開放すると、穀稈搬送装置６及びその近傍の清掃やメンテナンスを楽に行うことが出来る。 When the rear cover 8b of the dustproof cover 8 is opened by operating as described above, cleaning and maintenance of the grain stalk transport device 6 and its vicinity can be performed easily.
