The side operating box 7 on the left side of the driver's seat 5 is provided with a harvesting threshing clutch lever 9 that intermittently operates the rotational power transmitted to the harvesting device 4 and the threshing unit 3, and a continuously variable transmission that is not shown. Thereby, the shift lever (the travel shift lever 10, the sub shift lever 11) and the like of the traveling speed are changed.
收割裝置4由後支撐框架20a支撐，將該後支撐框架20a的基端部(後端部)轉動自如地軸支承於在行駛機體1上設置的未圖示的支撐部。並且，通過在後支撐框架20a的中間部與行駛機體1之間設置的收割升降缸S的由液壓驅動產生的伸縮，來使收割裝置4上下升降。 The harvesting device 4 is supported by the rear support frame 20a, and the base end portion (rear end portion) of the rear support frame 20a is rotatably supported by a support portion (not shown) provided on the traveling body 1. Further, the harvesting device 4 is moved up and down by the expansion and contraction of the harvesting lift cylinder S provided between the intermediate portion of the rear support frame 20a and the traveling body 1 by hydraulic pressure.
在後支撐框架20a的末端部(前端部)，連結有左右方向的橫支撐框架20b的左右中間部，從橫支撐框架20b朝向聯合收割機的機體前方在左右方向隔開預定間隔地配置有多個分草支撐框架21。 In the distal end portion (front end portion) of the rear support frame 20a, the left and right intermediate portions of the lateral support frame 20b in the left-right direction are connected, and the horizontal support frame 20b is disposed at a predetermined interval in the left-right direction toward the front of the body of the combine harvester. The grass supports the frame 21.
收割裝置4中裝備有：將生長著的穀物稈分離的多個分草工具(分草部件)14、將分離後的穀物稈提升的左右一對提升裝置15(左側提升裝置15L和右側提升裝置15R)、對提升後的穀物稈進行收割的推子式重力刀片裝置16、對收割後的穀物稈進行撥入搬送的星形輪等撥入搬送裝置17、將撥入搬送後的穀物稈上揚搬送至脫穀部來進行供給的上揚搬送裝置18等。 The harvesting device 4 is equipped with a plurality of weeding tools (grass parts) 14 for separating the grown grain stalks, and a pair of right and left lifting devices 15 for lifting the separated grain stalks (left side lifting device 15L and right side lifting device) 15R), a push-type gravity blade device 16 for harvesting the lifted grain stalks, a transfer conveyor device 17 for transferring and transporting the harvested grain stalks, and the like, and the grain stalks after the transfer and transport are raised. The lifting conveyor 18 and the like that are transported to the threshing unit for supply.
上述分草工具14包括左分草工具(左側的分草部件)14L和右分草工具(右側的分草部件)14R以及中央的中分草工具(中央側的分草部件)14C。 The above-described weeding tool 14 includes a left weeding tool (the left weeding member) 14L and a right weeding tool (the right weeding member) 14R and a centering middle weeding tool (the center side weeding member) 14C.
此外，各分草工具14安裝於分草支撐框架21的末端。 Further, each of the grass separating tools 14 is attached to the end of the grass-removing support frame 21.
左分草工具14L和右分草工具14R以繞上下方向的縱軸22(22L、22R)轉動自如的方式樞軸連接成末端側能夠朝向左內側方或右外側方轉動，該上下方向的縱軸22(22L、22R)設於分草支撐框架21的中途部。 The left divided grass tool 14L and the right divided grass tool 14R are pivotally connected so as to be rotatable about the vertical axis 22 (22L, 22R) in the vertical direction so that the distal end side can be rotated toward the left inner side or the right outer side, and the vertical direction vertical The shaft 22 (22L, 22R) is provided at a midway portion of the grass-dividing support frame 21.
正如圖7所示，在進行通常的2行切割作業時，左分草工具14L和右分草工具14R處於閉狀態，向左分草工具14L及右分草工具14R和中分草工具14C之間逐行導入穀物稈，左右合起來將2行穀物稈分離引導向重力刀片裝置16側。 As shown in Fig. 7, when the normal 2-row cutting operation is performed, the left-divided grass tool 14L and the right-divided grass tool 14R are in a closed state, and the left-dividing tool 14L and the right-dividing tool 14R and the middle-dividing tool 14C are The grain stalks are introduced row by row, and the two rows of grain stalks are separated and guided to the gravity blade device 16 side.
在使左分草工具14L和右分草工具14R中的左分草工具14L向外側方打開的狀態(開狀態)下，向中分草工具14C和左分草工具14L之間導入2行穀物稈，與向中分草工具14C和右分草工具14R之間導入的1行穀物稈合起來導入3行穀物稈(參照圖8)，從而能夠進行3行切割作業。 In a state in which the left divided grass tool 14L in the left divided grass tool 14L and the right divided grass tool 14R is opened to the outside (open state), two rows of grain are introduced between the middle divided grass tool 14C and the left divided grass tool 14L. The stalks are combined with one row of grain stalks introduced between the middle of the weeding tool 14C and the right weeding tool 14R to introduce three rows of grain stalks (see Fig. 8), so that three rows of cutting operations can be performed.
另外，在使左分草工具14L和右分草工具14R中的右分草工具14R向外側方打開的狀態(開狀態)下，向中分草工具14C和右分草工具14R之間導入2行穀物稈，與向中分草工具14C和閉狀態的左分草工具14L之間導入的1行穀物稈合起來導入3行穀物稈(參照圖9)，從而能夠與上述同樣地進行3行切割作業。 In addition, in a state (open state) in which the right weeding tool 14R of the left weeding tool 14L and the right weeding tool 14R is opened to the outside, the middle weeding tool 14C and the right weeding tool 14R are introduced 2 The grain stalks are combined with one row of grain stalks introduced between the middle stalking tool 14C and the closed left stalking tool 14L to introduce three rows of grain stalks (see Fig. 9), so that three rows can be carried out in the same manner as described above. Cutting work.
並且，正如圖10所示，在使左分草工具14L和右分草工具14R向外側方打開時，分別向左分草工具14L和中分 草工具14C之間以及右分草工具14R和中分草工具14C之間各導入2行穀物稈，左右合起來構成為能夠導入4行穀物稈，從而能夠進行4行切割作業。 Further, as shown in FIG. 10, when the left weeding tool 14L and the right weeding tool 14R are opened to the outside, the grass separating tool 14L and the middle are respectively divided. Two rows of grain stalks are introduced between the grass tools 14C and between the right weeding tool 14R and the middle weeding tool 14C, and the left and right sides are combined to form four rows of grain stalks, thereby enabling four rows of cutting operations.
然後，使變速桿10向前方傾斜移動，通過行駛履帶2L、2R使機體前進以進行切斷收割作業，但在聯合收割機的切斷收割作業中，從上方觀察田地，一邊繞轉半周一邊從周邊部向中心部收割穀物稈。 Then, the shift lever 10 is tilted forward, and the body is moved forward by the running crawlers 2L and 2R to perform the cutting and harvesting operation. However, in the cutting and harvesting operation of the combine harvester, the field is viewed from above while the half turn is rotated. The peripheral portion harvests the grain stalks toward the center.
2行切割作業(圖7)中，設定為當使右分草工具14R與已經收割過的穀物稈(既割穀物稈)的餘茬C的位置一致時在左分草工具14L和右分草工具14R之間導入2行穀物稈之間隔，因此，操縱者只要利用上述動力轉向桿8一邊對機體進行方向操縱一邊使機體前進以使位於駕駛座5的前方的右分草工具14R的位置在餘茬C的上方通過即可，從而使收割作業中的機體的操作變得容易。 In the 2-row cutting operation (Fig. 7), it is set to the left branching tool 14L and the right branching grass when the position of the right weeding tool 14R is the same as the position of the remaining stalk C of the already harvested grain stalk (cutting the grain stalk). The interval between the two rows of grain stalks is introduced between the tools 14R. Therefore, the operator only needs to use the power steering rod 8 to perform the direction manipulation of the body while advancing the body so that the position of the right weeding tool 14R located in front of the driver's seat 5 is at The upper side of the remaining c is passed, thereby making the operation of the body in the harvesting operation easy.
在3行切割作業中的圖8所示的作業中，對於左分草工具14L，使種植於田地的穀物稈K的位置與比該左分草工具14L靠內側的位置一致。該作業方式主要在收割壟間的穀物稈時使用，通過使左分草工具14L的末端接近機體的左方最外側，從而在收割壟間的穀物稈時不使機體與周圍的障礙物接觸就能夠進行作業，在周圍由混凝土壁包圍的都市區的田地等中極為有效。 In the operation shown in FIG. 8 in the three-row cutting operation, the position of the grain stalk K planted in the field is aligned with the position on the inner side of the left weeding tool 14L with respect to the left weeding tool 14L. The operation mode is mainly used when harvesting the grain stalk between the ridges, and the end of the left weeding tool 14L is close to the outermost left side of the body, so that the grain stalk between the ridges is not allowed to contact the surrounding obstacles when harvesting the stalks between the ridges. It is possible to carry out work and is extremely effective in fields such as urban areas surrounded by concrete walls.
圖9所示的3行切割作業適於使未收割穀物稈位於聯合收割機的機體的左右兩側而進行的所謂中央分割作業，使與行駛履帶2R的外側端之間的距離較大的右分草工具 14R的末端位於穀物稈K的近右側來進行收割，由此能夠確保相比該穀物稈K位於機體行進方向右側的穀物稈與行駛履帶2R之間的間隙來進行收割作業，從而能夠在使未收割穀物稈不被行駛履帶2R、2L踩踏的情況下進行中央分割作業。 The three-row cutting operation shown in Fig. 9 is suitable for a so-called center division operation in which the unharvested grain stalks are placed on the left and right sides of the body of the combine, so that the distance from the outer end of the running track 2R is large. Grass cutting tool The end of the 14R is located on the right side of the grain stalk K to be harvested, thereby ensuring a clearance operation between the grain stalk and the running track 2R on the right side of the grain stalk K in the traveling direction of the body, thereby enabling the harvesting operation. When the harvested grain stalk is not stepped on by the traveling tracks 2R and 2L, the center division operation is performed.
4行切割作業(圖10)中，能夠利用2行範圍的提升裝置15收割4行穀物稈，能夠飛躍性地提高收割作業的效率。特別是在進行前述的中央分割作業時是有效的，在收割作業中進行機體的方向轉換等時，也能夠在使穀物稈不被行駛履帶2R、2L踩踏的情況下進行作業。 In the 4-row cutting operation (Fig. 10), it is possible to harvest four rows of grain stalks by the lifting device 15 in two rows, and it is possible to dramatically improve the efficiency of the harvesting operation. In particular, it is effective to carry out the above-described center division work, and it is also possible to perform work when the grain stems are not stepped on by the running tracks 2R and 2L when the direction of the body is changed during the harvesting operation.
另外，如上所述，能夠使左分草工具14L和右分草工具14R的間隔從2行收割變更至最大4行收割，由此，在作業條件良好時(穀物稈為生長狀態且未附著雨水和泥土等時、或者穀物稈的穗部的穀粒比較少時)，通過將4行穀物稈導入收割裝置4，能夠減少在田地內移動的距離和進行機體的旋轉的次數，能夠進行高效的作業。 Further, as described above, the interval between the left weeding tool 14L and the right weeding tool 14R can be changed from two rows of harvesting to the maximum of four rows of harvesting, whereby when the working conditions are good (the grain stalk is in a growing state and no rainwater is attached) When the amount of grain in the ear portion of the grain stalk is relatively small, or when the grain of the stalk of the grain stalk is relatively small, the distance between the movement in the field and the number of rotations of the body can be reduced, and the number of times of the grain stalk can be reduced. operation.
另外，在預想到穀物稈倒伏、或淋濕、或穀粒多從而收割搬送及脫谷的負荷高的作業條件下，通過將導入收割裝置4的穀物稈的量限制為2行，能夠減輕收割裝置4及脫穀裝置3的負荷並進行穩定的作業。 In addition, it is expected that the amount of grain stalk introduced into the harvesting device 4 can be reduced to two rows under the operating conditions in which the grain stalks are lodging or wet, or the grain is large, and the load of the harvesting and the threshing is high. The load of the device 4 and the threshing device 3 is stabilized.
左分草工具14L和右分草工具14R和對其進行遠距離操作的操作桿13L、13R經由操作線23等而聯動連結，並且它們以如下方式聯繫起來：通過以各操作桿13L、13R的支點Q為中心向近前側(從前方向後方)進行拉引操作， 左分草工具14L向左外側方轉動，右分草工具14R向右外側方轉動的方式連接起來。此外，當操作桿13L、13R向前方進行推壓操作時，左分草工具14L和右分草工具14R復原為2行切割作業姿勢的閉狀態。另外，左右的操作桿13L、13R在側操作箱7側配置於副變速桿11的橫向側附近，並且在主視圖中配置成左右平行狀(參照圖12)。 The left divided grass tool 14L and the right divided grass tool 14R and the operating levers 13L, 13R for which remote operation is performed are linked by the operation line 23 or the like, and they are linked in such a manner as to pass through the respective operating levers 13L, 13R The fulcrum Q is pulled toward the front side (from the front to the rear). The left divided grass tool 14L is rotated to the left outer side, and the right divided grass tool 14R is connected to the right outer side. Further, when the operation levers 13L and 13R are pushed forward, the left blade dividing tool 14L and the right blade dividing tool 14R are restored to the closed state of the two-row cutting operation posture. In addition, the left and right operating levers 13L and 13R are disposed in the vicinity of the lateral side of the auxiliary shifting lever 11 on the side of the side operating box 7, and are arranged in a left-right parallel shape in the front view (see FIG. 12).
另外，正如圖4所述，左分草工具14L和右分草工具14R的末端部以重力刀片16的端部、即左右的分草支撐框架21L、21R為基準而向內側和外側轉動從而發生移位元，分草工具14L、14R後部的框架部不會從分草支撐框架21L、21R大幅地彎曲，因此能夠從分草工具14L、14R起在分草支撐框架21L、21R的整個範圍順滑地引導穀物稈的茬根。 Further, as shown in FIG. 4, the distal end portions of the left weeding tool 14L and the right weeding tool 14R are rotated toward the inside and the outside with reference to the ends of the gravity blade 16, that is, the left and right grass supporting frames 21L, 21R. Since the shifting element and the frame portion at the rear portion of the weeding tools 14L and 14R are not substantially bent from the grass-receiving support frames 21L and 21R, the entire range of the grass-converting support frames 21L and 21R can be slid from the weeding tools 14L and 14R. Slidingly guides the roots of the grain stalks.
將重力刀片裝置16的左右寬度A設定為比分別處於上述開狀態的上述左分草工具14L和右分草工具14R的末端間隔B1窄，因此對於導入至收割裝置4的穀物稈，從通常的收割行數起，能夠在該行數上多收割2行穀物稈，並使重力刀片裝置16的左右寬度在不對穀物稈的切斷性能造成妨礙的範圍內縮窄，由此能夠減小重力刀片裝置16所產生的振動及噪音。並且，能夠使收割裝置4緊湊地構成，使旋轉時收割裝置4難以與周圍的田埂等接觸，從而能夠提供操作性優異的聯合收割機。 The left and right widths A of the gravity blade device 16 are set to be narrower than the end spacing B1 of the left and right divided grass tools 14L and 14R respectively in the above-described open state, so that the grain stalk introduced into the harvesting device 4 is normal. When the number of harvesting lines is increased, two rows of grain stalks can be harvested in the number of rows, and the left and right widths of the gravity blade device 16 are narrowed within a range that does not hinder the cutting performance of the grain stalk, thereby reducing the gravity blade. Vibration and noise generated by the device 16. In addition, the harvesting device 4 can be configured in a compact manner, and it is difficult to bring the harvesting device 4 into contact with the surrounding field or the like during the rotation, and it is possible to provide a combine harvester having excellent operability.
另外，通過將重力刀片裝置16的左右寬度A設定為比分別處於上述閉狀態的左分草工具14L和右分草工具14R 的末端間隔B2寬，能夠相比導入至收割裝置4的作為收割物件的穀物稈量使重力刀片裝置16的切斷能力產生富餘，從而能夠可靠地收割穀物稈。 Further, by setting the left and right widths A of the gravity blade device 16 to the left branching tool 14L and the right branching tool 14R which are respectively in the above closed state, The end interval B2 is wide, and the cutting ability of the gravity blade device 16 can be made larger than the amount of the grain stalk which is introduced into the harvesting device 4 as the harvesting device, so that the grain stalk can be reliably harvested.
另外，左分草工具14L和右分草工具14R中的未收割地側(左側)的分草工具14L設定成：在使其朝向外側方伸出成開狀態時，該分草工具14L的末端相比未收割地側的行駛履帶2L的外端部位於外方(參照圖5)。由此，能夠防止未收割地側的穀物稈被未收割地側的行駛履帶2L踩踏。並且，在水田等柔軟地面上的作業中，未收割地側的行駛履帶2L向地面下沉，由此泥被擠壓向未收割地側，但由於分草工具14L的末端和重力刀片裝置16的外側端與該行駛履帶2L相比位於外側方，因此不會將泥土推至未收割穀物稈的茬根，不會對下一次的收割行程造成障礙。另外，圖5的例子中，在使左分草工具14L和右分草工具14R分別向外側同時打開的狀態下，中分草工具14C和左分草工具14L及右分草工具14R末端之間的距離C、D設定為大致相同的距離，在向內側同時關閉的狀態下，中分草工具和左右分草工具末端之間的距離也設定為大致相同距離。 Further, the undivided side (left side) of the left-dividing tool 14L and the right-dividing tool 14R is set such that the end of the weeding tool 14L is opened when it is extended outward. The outer end portion of the traveling crawler 2L on the unharvested side is located outside (see FIG. 5). Thereby, it is possible to prevent the grain stalk on the unharvested side from being stepped on by the traveling track 2L on the unharvested side. Further, in the operation on a soft ground such as a paddy field, the traveling track 2L on the unharvested side sinks to the ground, whereby the mud is pressed toward the unrecovered side, but the end of the weeding tool 14L and the gravity blade device 16 Since the outer end is located on the outer side of the traveling track 2L, the soil is not pushed to the root of the unharvested grain stalk, and the next harvesting stroke is not hindered. Further, in the example of Fig. 5, in a state where the left divided grass tool 14L and the right divided grass tool 14R are simultaneously opened to the outside, respectively, between the middle divided grass tool 14C and the left divided grass tool 14L and the right divided grass tool 14R end The distances C and D are set to be substantially the same distance, and the distance between the middle branching tool and the end of the left and right weeding tools is also set to be substantially the same distance in a state of being simultaneously closed to the inside.
各提升裝置15包括：構成為左右對稱形狀的提升殼體25；架設於殼體內上部的驅動鏈輪26、張緊鏈輪27；在左右隔開預定間隔地架設在殼體內下部的左右導向輥28a、28b；以及繞掛於驅動鏈輪26、張緊鏈輪27和左右導向輥28a、28b的帶有提升凸桿29的環形鏈30。在提升裝置15的始端側設有在橫向具有預定寬度的撥攏路徑(橫向移送 路徑)Y1，該撥攏路徑Y1將被提升凸桿29導入的穀物稈從外側朝向內側方的提升路徑(縱向移送路徑)Y2側撥攏。該撥攏路徑Y1在隔開預定間隔地配置的左右的導向輥28a、28b之間構成，並且，將該左右導向輥28a、28b之間的輥間距(軸心間距離)P1設定為與提升凸桿29、29之間的凸桿間距(安裝間隔)P2大致相等，由此在該撥攏路徑Y1中，多個提升凸桿29、29以朝下的作用姿勢橫向移動。此外，在提升路徑Y2中，提升凸桿29以橫向姿勢上升移動。 Each lifting device 15 includes: a lifting housing 25 configured to have a bilaterally symmetrical shape; a drive sprocket 26 mounted on the upper portion of the housing; a tension sprocket 27; and left and right guide rollers erected at a lower portion of the housing at a predetermined interval from left to right 28a, 28b; and an endless chain 30 with lifting bosses 29 wound around the drive sprocket 26, the tensioning sprocket 27 and the left and right guiding rollers 28a, 28b. A leading path having a predetermined width in the lateral direction is provided on the start end side of the lifting device 15 (transverse transfer) Path) Y1, which is the side of the lifting path (longitudinal transfer path) Y2 side of the grain stalk introduced by the lifting ram 29 from the outer side toward the inner side. The folding path Y1 is formed between the left and right guide rollers 28a and 28b which are disposed at predetermined intervals, and the roller pitch (inter-axis distance) P1 between the left and right guide rollers 28a and 28b is set to be raised and raised. The ridge pitch (mounting interval) P2 between the ribs 29, 29 is substantially equal, whereby in the plucking path Y1, the plurality of lifting ribs 29, 29 are laterally moved in a downward acting posture. Further, in the lift path Y2, the lift boss 29 is moved upward in the lateral posture.
即，當提升凸桿29在撥攏路徑Y1的終端位置附近移動時、或在從撥攏路徑Y1向提升路徑Y2轉移的過程中以描繪圓弧軌跡的方式移動時，即使穀物稈從與提升凸桿29卡合的狀態脫離，也能夠因在撥攏路徑Y1中存在其他的提升凸桿29而擋住穀物稈，能夠防止提升裝置15中的穀物稈的漏收。 That is, even when the lifting bulge 29 moves in the vicinity of the end position of the plucking path Y1, or in the process of drawing the circular trajectory during the transition from the plucking path Y1 to the lifting path Y2, even if the grain stalk is lifted and lifted When the state in which the bosses 29 are engaged is disengaged, the grain stalks can be blocked by the presence of the other lifting bosses 29 in the plucking path Y1, and the leakage of the grain stalks in the lifting device 15 can be prevented.
因此，根據上述結構的撥攏路徑Y1，即使向單側導入2行穀物稈也能夠可靠地向提升路徑Y2內撥攏。 Therefore, according to the plucking path Y1 of the above configuration, even if two rows of grain stalks are introduced to one side, it is possible to reliably pluck into the lifting path Y2.
此外，上述凸桿間距P2比輥間距P1加上導向輥28a的外周長的1/4而得的長度要短，優選比輥間距P1加上導向輥28a的外周長的1/8而得的長度要短。通過如上所述地設定輥間距P1與凸桿間距P2，能夠防止提升裝置15中的穀物稈的漏收，從而能夠良好地進行提升。 Further, the pitch P2 is shorter than the roll pitch P1 plus 1/4 of the outer circumference of the guide roller 28a, and is preferably obtained by adding 1/8 of the outer circumference of the guide roller 28a to the roll pitch P1. The length should be short. By setting the roll pitch P1 and the boss pitch P2 as described above, it is possible to prevent the grain stalk in the lifting device 15 from leaking, and it is possible to perform the lifting favorably.
另外，正如圖6所示，上述左分草工具14L和右分草工具14R構成為：在處於向外側打開的狀態和向內側關閉 的狀態中的任一狀態下，左分草工具14L和右分草工具14R在主視圖中的內側端部都與提升凸桿29的移動軌跡重合。 Further, as shown in Fig. 6, the left weeding tool 14L and the right weeding tool 14R are configured to be open to the outside and closed to the inside. In either of the states, the inner side ends of the left and right divided grass tools 14L and 14R in the front view coincide with the movement trajectory of the lifting ram 29 .
提升凸桿29在非提升作用側以沿著環形鏈30的倒伏姿勢移動，當到達導向輥28a的側方時，該提升凸桿29的基部與該導向輥28a抵接而成為立起姿勢，但通過使左分草工具14L和右分草工具14R在主視圖中的內側端部與立起姿勢的提升凸桿29的軌跡重合，能夠使被左分草工具14L和右分草工具14R分離後的穀物稈順利地向成為立起姿勢的提升凸桿29交接。 The lifting bead 29 moves along the unfolding posture of the endless chain 30 on the non-lifting action side, and when reaching the side of the guide roller 28a, the base of the lifting bead 29 abuts against the guide roller 28a to be in an upright position. However, by overlapping the trajectory of the left side grass tool 14L and the right weeding tool 14R in the front view with the erecting bulge 29 of the standing posture, the left side grass tool 14L and the right grass dividing tool 14R can be separated. The rear grain stalk smoothly passes to the lifting ram 29 which is in the standing posture.
並且，在使左分草工具14L和右分草工具14R向內側關閉的狀態下，形成為在左右方向與導向輥28a的軸心位置接近的狀態，因此在左分草工具14L和右分草工具14R與提升凸桿29之間，幾乎沒有該提升凸桿29未作用的區域，能夠將分離引導後的作為收割物件的穀物稈可靠地朝向提升路徑Y2撥攏，能夠盡可能地減少穀物稈的漏收。 Further, in a state where the left weeding tool 14L and the right weeding tool 14R are closed inward, the left-right direction is in a state of being close to the axial center position of the guide roller 28a, so that the left-dividing tool 14L and the right-handed grass are formed. Between the tool 14R and the lifting ram 29, there is almost no area where the lifting ram 29 is inactive, and the grain stalk as the harvesting object after the separation and guidance can be reliably moved toward the lifting path Y2, thereby reducing the grain stalk as much as possible.

即，撥入凸桿42在側視圖中向後上方移動，因此當撥入凸桿42從撥入開始位置向後側移動時，撥入凸桿42的移動軌跡變高，因此穀物桿的上側部分被搬送而穀物桿的中間部下垂，搬送姿勢錯亂，但在本申請中，撥入凸桿42前端的移動軌跡與提升裝置15的提升殼體25的下端大致等高，因此撥入凸桿42從穀物桿的下側部分開始進行作用，使得穀物桿搬送姿勢良好，搬送性能提高。 That is, the dialing projection 42 is moved rearward and upward in the side view, so that when the dialing projection 42 is moved from the dialing start position to the rear side, the movement locus of the dialing projection 42 becomes high, so that the upper side portion of the cereal stem is The middle portion of the grain stem is drooped and the transport posture is disordered. However, in the present application, the movement locus of the front end of the dialing projection 42 is substantially equal to the lower end of the lift housing 25 of the lifting device 15, so that the dial 42 is dialed from The lower portion of the grain rod starts to act, so that the grain rod is transported in a good posture and the transport performance is improved.
此外，撥入凸桿42的移動軌跡的前端配置在比提升裝置15的提升凸桿29的轉動中心靠下方的位置(例如圖18)。 Further, the front end of the movement locus of the dialing projection 42 is disposed at a position lower than the center of rotation of the lifting boss 29 of the lifting device 15 (for example, FIG. 18).
因此，撥入凸桿42的搬送作用區域H的前端部比提升裝置15的導向輥28a和導向輥28b的各旋轉中心靠下方，因此撥入凸桿42從穀物桿的下側部分開始進行作用，使得穀物桿搬送姿勢良好，搬送性能提高。 Therefore, the front end portion of the transfer action region H of the dialing projection 42 is lower than the respective rotation centers of the guide roller 28a and the guide roller 28b of the lifting device 15, so that the dialing projection 42 acts from the lower portion of the cereal stem.

Further, the rear end portion of the guide portion 48 is a free end toward the lower portion of the front portion of the upwardly-lifting conveyance device 18, and the branch guide portion 48A extending from the end portion of the intermediate portion of the guide portion 48 toward the rear right side is fixed to the left-right direction from the lateral support frame 20b. A longitudinal drive barrel 49 extending in the up and down direction.
上揚搬送裝置18構成為始端側能夠以終端側的橫向軸心為轉動支點在上下方向變更位置，從而能夠與穀物稈的長短對應地任意調節向滾筒室內的供給深度。 The lifting conveyance device 18 is configured such that the starting end side can change the position in the vertical direction with the lateral axis of the terminal side as a pivot point, and the supply depth to the drum chamber can be arbitrarily adjusted in accordance with the length of the grain stalk.
在圖20所示的操作面板6a裝備有顯示器D，當左右 的分草工具的一方或兩方為“打開”時，在畫面上顯示“請使副變速為低速”之類的注意事項。通常，在2行切割作業中以標準的作業速度進行作業，但其變為3行切割或4行切割作業時，存在能力上困難之處，因此優選使作業速度降低1級從而以低速度進行作業。因此，操作員只要按照該顯示將副變速切換為低速進行作業即可。 The operation panel 6a shown in FIG. 20 is equipped with a display D, when When one or both of the dividing tools are "open", the precautions such as "Please make the auxiliary shift to low speed" are displayed on the screen. Usually, in a 2-line cutting operation, the work is performed at a standard working speed, but when it becomes a 3-line cutting or a 4-row cutting operation, there is a difficulty in the performance, so it is preferable to lower the working speed by one step to perform at a low speed. operation. Therefore, the operator only needs to switch the sub-shift to the low speed in accordance with the display.
此外，也可以取代上述的顯示器而裝備發聲器，通過聲音向操作員進行通知。 Further, the sounder may be equipped instead of the above-described display, and the operator may be notified by sound.
另外，也可以構成為：在左右的分草體14L、14R變為開狀態時，自動地使行駛車速的上限降低。 In addition, when the left and right weeds 14L and 14R are in an open state, the upper limit of the traveling vehicle speed may be automatically lowered.
即，左右的分草體14L、14R和對其進行遠距離操作的操作工具(操作桿)13L、13R經由操作線23等連接部件而聯動連結，並且它們以如下方式聯繫起來：通過各操作桿13L、13R的以支軸12為軸心的向近前側(從前方向後方)的拉引操作，使左分草體14L向左外側方轉動，並使右分草體14R向右外側方轉動。此外，當操作桿13L、13R向前方進行推壓操作時，左右的分草體14L、14R復原到2行切割作業姿勢的閉狀態。另外，左右的操作桿13L、13R在側操作面板7側配置於變速桿(行駛變速桿10和副變速桿11)的橫向側附近。 That is, the left and right weeds 14L, 14R and the operating tools (operating levers) 13L, 13R for remotely operating them are linked by a connecting member such as the operating wire 23, and they are linked in such a manner that they pass through the operating levers. The drawing operation of the 13L and 13R with the support shaft 12 as the axial center toward the front side (from the front to the rear) rotates the left divided grass body 14L to the left outer side and rotates the right divided grass body 14R to the right outer side. Further, when the operation levers 13L and 13R are pushed forward, the left and right grass blades 14L and 14R are restored to the closed state of the two-row cutting operation posture. Further, the left and right operating levers 13L and 13R are disposed on the side of the side operating panel 7 on the lateral side of the shift lever (the traveling shift lever 10 and the sub shift lever 11).
行駛變速箱M所具備的副變速裝置能夠被副變速桿11切換成高速(路上行駛速度)、中速(收割標準速度)和低速(收割作業倒伏速度)這3級。即，在作業速度的副變速切換中具有“標準”和“倒伏”的聯合收割機構成 為：在左右的分草體14L、14R的開狀態下，與操作桿13的操作聯動地將副變速桿11切換至“倒伏”位置。 The sub-transmission device provided in the traveling gearbox M can be switched by the sub-shift lever 11 to three stages of high speed (road traveling speed), medium speed (harvesting standard speed), and low speed (harvesting work lodging speed). That is, a combine harvester having "standard" and "falling" in the auxiliary shifting of the working speed In the open state of the left and right weeds 14L, 14R, the sub shift lever 11 is switched to the "down" position in conjunction with the operation of the operating lever 13.
通常，在2行切割作業中按照“標準”的作業速度進行作業，但其變為3行切割或4行切割作業時，在能力上存在不足之處，因此優選使作業速度降低1級從而以低速度進行作業。 Usually, in the 2-line cutting operation, the work is performed at the "standard" working speed, but when it becomes a 3-line cutting or a 4-row cutting operation, there is a deficiency in the ability, so it is preferable to lower the working speed by one step so that Work at low speeds.
因此，正如圖21所示，在對操作桿13向開狀態位置進行操作時，副變速桿11經由聯動部件31向“倒伏”位置移動，作業速度切換成比標準速度要低的速度。在操作桿13的閉狀態位置，通過在聯動部件31上設置長孔32，能夠變更副變速位置。 Therefore, as shown in FIG. 21, when the operation lever 13 is operated in the open state position, the sub-shift lever 11 is moved to the "downward" position via the interlocking member 31, and the work speed is switched to a speed lower than the standard speed. At the closed state position of the operation lever 13, the auxiliary shifting position can be changed by providing the long hole 32 in the interlocking member 31.
另外，正如圖22所示，在對分草體的操作桿13向開狀態位置進行操作時，行駛變速桿10經由聯動部件31和牽制單元33移動直至限制預定範圍的前進側操作區域的位置，並牽制進一步向前進側高速區域的移動。此外，在分草體的閉狀態下，能夠通過設於聯動部件31的貫通孔34來解除限制。 Further, as shown in FIG. 22, when the operation lever 13 of the grass is operated in the open state position, the travel shift lever 10 is moved via the interlocking member 31 and the pinching unit 33 until the position of the forward side operation region of the predetermined range is restricted. Further, the movement to the high speed region on the forward side is pinned. Further, in the closed state of the divided body, the restriction can be released by the through hole 34 provided in the interlocking member 31.
在以上的實施例中，為了方便對設有2台提升裝置15的收割裝置4進行了說明，但收割裝置4的通常的收割行數也可以為3行以上，此時，設置與收割裝置4的通常的收割行數相應數量的提升裝置15、以及撥入裝置和搬送裝置，在位於左右最外側的提升裝置的外側前方設置左右的分草工具14L、14R，在各提升裝置15之間的前方位置分 別配置中分草工具14C即可。 In the above embodiment, the harvesting device 4 provided with the two lifting devices 15 has been described for convenience.
