(6). Structure of Side Divider and Divider Lever Next, the structure of the side divider 240 and the divider lever 250 will be described mainly with reference to FIGS. As shown in FIG.11 and FIG.12, the side divider 240 is provided in the horizontal one side part (left side part in embodiment) of the cutting device 3. As shown in FIG. The side divider 240 removes the uncut cereals laterally so that the traveling machine body 1 that moves forward does not entrain the uncut cereals on the side of the side or step on the traveling crawler 2 during the harvesting operation. It is for pushing (crawling) in a direction (a direction away from one lateral side of the traveling machine body 1).

  The side divider 240 is configured to be able to be swung up and stored so as to be close to the reaping device 3. That is, the side divider 240 is a work posture that protrudes outward in the lateral direction by the up-and-down rotation (undulation rotation) with the portion near the lateral side of the cutting device 3 as a fulcrum (solid lines in FIGS. 11 and 12). The state can be changed between a state (see the state) and a storage posture (see the two-dot chain line state in FIG. 11) that stands up close to the reaping device 3.

  In the embodiment, a front bracket plate 241 that protrudes outward in the left-right direction is fixed to a pull-up support frame 38 b that is erected on the leftmost weed frame 38. The front side of the side divider 240 made of a metal pipe is rotatably connected to the front bracket plate 241 via a longitudinal longitudinal shaft pin 242 (see FIG. 12). Further, as shown in FIG. 11, the rear bracket plate 243 is fixed to the back side of the cutting blade drive unit 49 disposed at the left end portion of the lateral transmission frame 37. A rotating plate 245 is rotatably connected to the rear bracket plate 243 via a longitudinally supporting pin shaft 244 located on the same axis as the shaft pin 242. A rocking pipe 240 a extending from the middle part of the side divider 240 toward the inside of the machine body is fixed to the rotating plate 245. In this case, by rotating the rotation plate 245 around the pivot pin shaft 244, the swing pipe 240a and thus the side divider 240 rotate around the common axis of the shaft pin 242 and the pivot pin shaft 244. As a result, the side divider 240 changes the posture between the working posture and the storage posture.

  The rotating plate 245 is formed with a substantially arcuate guide slot 246 centered on the pivot pin shaft 244. A regulation pin 247 fixed to the rotating plate 245 is inserted through the guide slot. The movable range of the restriction pin 247 restricted by the guide slot 246 determines the undulating and turning stroke of the side divider 240 (the undulating and turning range of the side divider 240 is restricted by the guide slot 246).

  As shown in FIGS. 11 to 13, the side divider 240 is placed in a position in the upper part of the grain raising device 31 in the reaping device 3 so as to enter the field of view of the operator looking forward from the operating unit 10 of the traveling machine body 1. A divider lever 250 is disposed as manual operation means for performing a posture change operation. The divider lever 250 of the embodiment extends sideways along the pulling input lateral case 40 located at the top of the grain raising device 31. The tip grip portion 250a of the divider lever 250 is bent upward. On the other hand, a horizontally elongated guide groove 252 is formed in the operation guide plate 251 fixed to the left and right center side of the fastening bracket 122. The tip grip portion 250a of the divider lever 250 penetrates the guide groove 252 of the operation guide plate 251 upward from below. Therefore, the divider lever 250 can be slid left and right along the guide groove 252 of the operation guide plate 251. The sliding range of the divider lever 250 is restricted by the guide groove 252.

  The divider lever 250 and the side divider 240 are interlocked and connected via a relay link rod 253 that extends vertically along the pulling input vertical case 39 disposed on the left side of the reaping device 3. In the embodiment, as shown in detail in FIG. 13, a link bracket 254 is bolted to a corner portion connecting the pulling input horizontal case 40 and the pulling input vertical case 39. The link bracket 254 is fixed with a longitudinal longitudinal link support shaft 255 penetrating the link bracket 254. On the rear side of the link support shaft 255, a corner boss portion 256a of the link arm 256 is rotatably fitted and cannot be removed. The base end side of the divider lever 250 is pivotally attached to the free end side of the vertical arm portion 256b in the link arm 256 by a pin facing forward and backward. The upper end side of the relay link rod 253 is pivotally attached to the free end side of the horizontal arm portion 256c in the link arm 256 by a forward and backward pin. The lower end side of the relay link rod 253 is pivotally attached to the rotation plate 245 with a front and rear facing pin (see FIGS. 11 and 12).

  By the left / right sliding operation of the divider lever 250, the link arm 256 rotates around the link support shaft 255, and the relay link rod 253 is pushed up and down. As a result, the rotating plate 245 rotates up and down around the pivot pin shaft 244 to change the attitude of the side divider 240 between the working attitude and the storage attitude. Here, in the embodiment, when the divider lever 250 is slid to the left side away from the driving unit 10, the side divider 240 is in a working posture in which it is separated laterally outwardly, and the divider lever 250 is slid to the right side approaching the driving unit 10. Then, the side divider 240 is configured to be in a storage posture close to the cutting device 3. As is clear from FIG. 11, the divider lever 250, the link arm 256, and the relay link rod 253 are arranged along the pulling input horizontal case 40 or the pulling input vertical case 39, and Separated from the grain transport route. Therefore, there is no possibility that the harvested cereals are prevented from being transported by the operation system of the side divider 240.

  Note that a horizontally long cylindrical boss body 257 is fitted to the proximal end side of the divider lever 250 in the embodiment so as not to be laterally displaceable and relatively rotatable. A connecting piece 258 fixed to the cylindrical boss body 257 is pivotally attached to a free end side of the vertical arm portion 256b of the link arm 256 by a front and rear facing pin. Therefore, the divider lever 250 can be tilted in the front-rear direction around the longitudinal axis. On the other hand, a notch groove extending forward is formed at each of the left and right ends of the guide groove 252 in the operation guide plate 251. By tilting the front end grip 250a of the divider lever 250 toward each notch groove, the divider lever 250 is held so as not to slide left and right. As a result, the side divider 240 is held in the working posture or the storage posture.

(7). Next, the structure of the pulling transmission case 39b and the pulling transmission lever 260 will be described with reference mainly to FIG. 11, FIG. 12, and FIG. As shown in FIGS. 11 and 12, a pulling transmission case 39 b incorporating a pulling transmission mechanism, which is a transmission gear mechanism, is provided in the longitudinal middle portion of the pulling input vertical case 39. In the embodiment, the pulling speed change mechanism is associated with the pulling input vertical axis 39a in the pulling input vertical case 39, and the driving force of the grain raising device 31, that is, the driving speed of the pulling tine 42b in each pulling case 42 is set to be high or low. It is configured to be variable in two stages (see FIG. 5).

  A shift fork (not shown) provided on a shift shaft 261 for shifting operation that vertically penetrates the pulling transmission case 39b is connected to the transmission gear 39c that is a component of the pulling transmission mechanism. By shifting the shift shaft 261 and then the shift fork up and down, the gear meshing with the transmission gear 39c is alternatively selected, and the drive speed of the pulling tine 42b in each pulling case 42 is shifted in two stages, high speed and low speed. Become.

  As shown in FIGS. 11, 12, and 14, a pulling shift lever 260 serving as a pulling manual operation means is pivoted left and right on a cutting upper frame 121 positioned below the upper cover 120 that covers the upper surface side of the cutting device 3. Supported as possible. In the embodiment, the lever bracket 262 is fixed to the upper surface side of the midway portion in the upper cutting frame 121. The lever bracket 262 is connected to a longitudinal midway portion of the longitudinal transmission lever 260 that is long in the front and rear directions by a vertically oriented pin. The leading grip portion of the pulling speed change lever 260 is located on the left side of the driving unit 10 in the traveling machine body 1.

  The pulling shift lever 260 and the shift shaft 261 are linked and connected in parallel with the divider lever 250 via a shift link rod 263 extending laterally along the upper portion of the grain pulling device 31 (the pulling input lateral case 40). . In the embodiment, as shown in detail in FIG. 14, the corner portion of the L-shaped arm 264 is fitted on the front side of the link support shaft 255 fixed to the link bracket 254 so that it can rotate and cannot be removed. Yes. One end side of the speed change link rod 263 is pivotally attached to the free end side of the vertical arm portion 264b in the L-shaped arm 264 via a pin facing forward and backward. The other end side of the speed change link rod is pivotally attached to the other end side of the pulling speed change lever 260 via a vertically oriented pin. The upper end side of the shift shaft 261 is pivotally attached to the free end side of the lateral arm portion 264c in the L-shaped arm 264 with a front-rear pin.

  In this case, the rotation center of the link arm 256 and the L-shaped arm 264 are both the link support shaft 255 and are common. Further, as apparent from the fact that the link arm 256 and the L-shaped arm 264 are arranged separately on the front and rear sides with the link bracket 254 interposed therebetween, the divider lever 250 and the transmission link rod 263 are raised without interfering with each other. They are arranged in parallel along the input lateral case 40.

  By the left / right turning operation of the pulling shift lever 260, the speed change link rod 263 slides left and right, the L-shaped arm 264 turns around the link support shaft 255, and the shift shaft 261 is pushed up and down. As a result, the drive speed of the pulling tine 42b in each pulling case 42 is shifted in two stages, high speed and low speed.

(8). Second Summary As is apparent from the above description and FIGS. 11 to 13, a side divider 240 is provided on the lateral side of the reaping device 3 so as to protrude outward in the lateral direction and push the uncut grain culm. The side divider 240 is a combine that can be swung up and stored so as to be close to the reaping device 3, and is a manual operation for mechanically changing the attitude of the side divider 240. Since the means 250 is provided in the upper part of the grain raising apparatus 31 in the reaping device 3 at a position entering the field of view of the operator who is looking forward from the operating unit 10 of the traveling machine body 1, the operating unit 10 The manual operation means 250 easily enters the field of view of the boarded operator, and it becomes easy to notice that the side divider 240 is in the working posture before entering the harvesting operation. For this reason, forgetting to take out the side divider 240 during the harvesting operation can be suppressed. In addition, the operator can easily grasp the arrangement position of the manual operation means 250 and is highly convenient. In addition, since the side divider 240 and the manual operation means 250 for posture changing operation are mechanically linked, the structure for changing the posture of the side divider 240 is compared with, for example, an actuator. Then, the structure is simple, it is difficult to break down, and the manufacturing cost can be kept low.

  As is clear from the above description and FIGS. 11 to 13, the manual operation means 250 extends laterally along the upper part of the grain raising device 31, and the side divider 240 and the manual operation means 250 are , And interlockingly connected via a relay link rod 253 extending vertically along the pulling vertical pipe 39 disposed on the left and right sides of the reaping device 3, and by sliding the manual operation means 250 left and right, Since the relay link rod 253 moves up and down to change the posture of the side divider 240, for example, the posture of the side divider 240 itself can be changed manually during handling operation, and the manual operation means 250 These operation states can also be switched according to the posture of the side divider 240. Therefore, the handleability of the side divider 240 is improved.

  In particular, in the embodiment, when the manual operation means 250 is operated in a direction away from the operation unit 10, the side divider 240 is in a working posture in which the side divider 240 is separated outward in the lateral direction, and the manual operation means 250 approaches the operation unit 10. When the operation is performed in the direction, the side divider 240 is placed in the retracted position close to the mowing device 3, so that the relationship between the operation state of the manual operation means 250 and the attitude of the side divider 240 is intuitive and easy to understand. There is also an advantage of superiority.

  In addition, since the manual operating means 250 is along the upper part of the grain raising device 31 and the relay link fence 253 is along the raising vertical pipe 39, the operation system of the side divider 240 is the grain feeding of the harvested grain rice cake. You will leave the route. That is, the structure (operation system) for changing the attitude of the side divider 240 can be configured simply and compactly without hindering the transportation of the harvested cereal while being a mechanical coupling mechanism.

  As is clear from the above description and FIGS. 11, 12, and 14, a pulling transmission case 39 b that shifts the driving force of the grain raising device 31 is disposed in the middle of the pulling vertical pipe 39. The pulling manual operation means 260 linked to the shift shaft 261 for shifting operation in the pulling transmission case 39b is connected to the cutting upper frame 121 positioned below the upper cover 120 covering the upper surface side of the cutting device 3 in the left-right direction. A shift link rod 263 that is movably supported and relays the pulling manual operation means 260 and the shift shaft 261 along the upper portion of the grain pulling device 31 in parallel with the manual operation means 250. Since it extends in the horizontal direction, not only the operation system of the side divider 240 but also the operation system of the pulling transmission case 39b is employed. While, it is constructed simple and compact without interfering with the transport of the cutting culms. Since the manual operation means for pulling 260 is supported by the upper cutting frame 121 below the upper cover 120 so as to be able to turn left and right, when the manual operation means for pulling 260 is operated, Existence does not get in the way.

(9). Next, the detailed structure of the grain raising device 31 for four-row cutting will be described mainly with reference to FIGS. 15 to 28. As shown in FIG. 5 and FIG. 15 and the like, the grain raising apparatus 31 is provided with four raising cases 42 having a plurality of raising tines 42a for raising an uncut grained rice cake in the field. As shown in FIGS. 17, 18, and 20 to 24, each pulling case 42 is formed in a vertically long hollow shape by a pair of front and rear front plates 271 and 272.
