１６が受け継いで搬送する。The lower sprocket 9a around the rear end of the stock raking chain 9 on the cut ground side and the upper sprocket around the start end of the stock merging and conveying chain 16 are wound. A star wheel 20 having a large number of projections having a gentle curve and a sweepback angle is interposed between the star A and the shaft A, as shown in FIG. The wheel 20 has a larger diameter than the trajectory including the protrusions of the stock raking chain 9 and the stock merging / conveying chain 16. An anti-winding rod 20a substantially perpendicular to the front surface in the rotation direction is also provided. Further, an extension of the tip of the stock guide rod 18 is provided inside the inheriting portion opposite to the winding prevention rod 20a. The scraping gear The rod 9b is disposed so as to be continuous with the end of the rod 9b. The rod 9b sequentially advances along the upper surface of the stock raking chain 9 toward the rear and moves along the raking path and moves the long protrusion a. After lapping with the track, the stock merging chain 1 is placed close to the upper surface of the star wheel 20.
Since the guide plate 19 is provided to extend rearward below the lower portion 6, the protrusion of the star wheel 20 is used to start and move the stock base portion nipped and conveyed by the stock raking chain 9 and the raking guide rod 9 b. The protrusion of the wheel 20 and the guide plate 19 push out the protrusion a of the stock raking chain 9 reliably, and the extension of the tip of the stock guide rod 18 prevents the stalk of the grain from spilling out of the passage. Then, when the grain stalk is caught on the star wheel 20 when it is pushed out into the horizontal transport path and delivered to the stock merging and transport chain 16 and subsequently retreats from the transport path, the winding prevention rod 20a removes it. Then, the stock source merging and transporting chain 16 carries over the same.

Between the stock-raising chain 9 and the raking guide rod 9b while being scraped by the raking chains 9 and the mowing blades by the cutting blade 3a, and further being raked to the rear lateral transport path. And transported vertically. The stems of the grain stalks that were scraped from the scraping path on the cut ground side were two
The stem is transferred by the horizontal transfer chains 17a and 17b, and the stock base is transferred to the start end of the stock merge transport chain 16. At this time, the holding with the scraping guide rod 9b is temporarily released at this transfer part. The large-diameter star wheel 20 reliably pushes off the stem portion of the grain stalk that has been pressed against the conveying surface of the stock raking chain 9 at the front side in the rotation direction of the projection, but the stock inside the inherited portion is removed. The extension of the former guide rod 18 prevents the stalks from spilling to the outside of the passage and is delivered to the stock former conveyer chain 16, and the surface having the curved receding angle of the projection rotates while coming out backward. the protrusion grain稈又becomes that the winding with anti rod 20a and straw dust, etc. is caught to disengage by receiving it, or poppy稈抜this taking over part, or clogged disturbed稈姿posture, or wound around Never do.

In particular, when the harvested grain culm is transferred while the direction is changed from the vertical conveyance end by the stock ramming chain 9 on the uppermost side in the grain culm merging direction to the horizontal conveyance by the stock convergence conveyance chain 16, The same as both sprockets 9a, 16a between the lower sprocket 9a at the end of the raking chain 9 and the upper sprocket 16a at the start end of the stock merging and conveying chain 16.
The large-diameter star wheel 20 attached to the shaft A of the grain is transported by the stock raking chain 9 at the inheriting portion released from being held between the two guide rods 9b and 18 between the two chains 9 and 16. The stem portion of the culm enters from the outside and is pushed away, and then transferred to the stem merging / conveying chain 16 while changing the conveyance direction, thereby improving the separation of the culm from the stem raking chain 9 and The transfer to the stock-merge conveyer chain 16 can be performed smoothly,
In addition, inside the transfer portion, the scraping guide rod 9b is provided.
Following the end of the stalk, the extension on the tip side of the stock guide rod 18 is substantially aligned with the rotation trajectory of the tip of the star wheel 20, resulting in culm leakage, culm breakage, culm clogging and winding at the inheritance part. It can be reliably prevented.
