A cutting section A for cutting the planted grain culm is provided at the front of the machine body, and the culm cut by the cutting section A is configured to be conveyed to the rear threshing apparatus 1.
With the end portion of the stock transfer side chain 5a of the vertical conveyance device 5 facing the start end of the feed chain 6 of the threshing device 1, the transfer of the harvested grain culm can be performed. [0007] At the start end of the feed chain 6, a takeover guide guide 7 faces from the front side in the transport direction. The transfer guide 7 transfers the grain stem between the vertical transport device 5 of the cutting unit A and the feed chain 6 of the threshing device 1. The transfer guide 7 is integrally attached to an openable / closable handle cover 8 of the threshing apparatus 1. In the embodiment shown in FIGS. 1 and 2, it is attached to the front side wall of the handling cylinder cover 8, but the left side wall, the upper side wall,
Alternatively, any portion that can be attached, such as the holding rod 8a, may be used. Further, if the transfer guide 7 is rotatable and foldable from the vicinity of the intermediate portion 7a, the transfer between the vertical transport device 5 and the feed chain 6 can be easily performed without opening the handling cylinder cover 8. Can perform maintenance management around the department.
At this time, as in the prior art, such as a drawback of the prior art, such as a portion other than the handle cover 8, for example, the driver's side wall 9 a or the upper portion of the tip side transfer device 5 b of the vertical transfer device 5, the takeover guide guide 7 is used. In, the harvesting unit A may be attached to a portion where the culm being transported is not caught or does not interfere with the maintenance management such as the vertical transport device 5 of the cutting unit A. Further, in the reaping section A having a reciprocating mechanism, if the handover guide 7 is provided on the handle drum cover 8 which can be opened and closed and does not move in the left-right direction of the threshing apparatus 1, the reaping section A and the vertical Since the transfer guide 5 is not restricted by the change in the right and left positions of the transfer device 5, the transfer between the vertical transfer device 5 and the feed chain 6 is stabilized, and a series of operations from harvesting to threshing can be performed smoothly. Next, FIGS. 4, 5 and 6 will be described. FIG. 4 shows the stock transfer device 10 and the reaper 1 of the reaper A.
1 is a plan view of FIG. The grain stalks weeded by the weeding tool 12 of the mowing part A are caused by the grain stalk raising device 13 shown in FIG. The harvested grain culm is converged at the center by the stock carrier 10 and the conveyed grain culm is transported by the vertical transport device 5 toward the rear threshing device 1 provided with the feed chain 6. The position of the blade presser 14 that holds down and fixes the upper and lower cutting blades 15 and 16 of the cutting device 11 of the cutting section A is determined by the transfer passage section 10 a through which the grain culm is transferred by the stock transfer apparatus 10. Near the bottom. As a result, when the harvested culm is conveyed by the stock transfer device 10, it always passes while contacting the upper portion of the blade presser 14, so that soil or the like is prevented from adhering to the front side in the conveying direction of the blade presser 14. it can. The upper cutting blade 15 and the lower cutting blade 16 of the cutting device 11 are both bent downward as shown in FIG. Conventionally, as shown in FIG. 5, the mating surfaces of the upper cutting blade 15 and the lower cutting blade 16 are in the same plane, so if the wear of the upper cutting blade 15 and the lower cutting blade 16 progresses as the use time increases,
The gap between the upper cutting blade 15 and the lower cutting blade 16 is widened, and the stalks, pebbles, and the like are scraped into the gap, and the cutting ability is greatly reduced. Therefore, if the upper cutting blade 15 and the lower cutting blade 16 are worn similarly as shown in FIG. 6, the gap between the upper cutting blade 15 and the lower cutting blade 16 is widened. The tip surface 15a of the blade 15 serves as a protective wall for preventing the intrusion of grain stalks, pebbles, and the like between the upper cutting blade 15 and the lower cutting blade 16, so that the cutting ability is not significantly reduced. According to the above description, the transfer guide guide 7 is provided on the openable handle cylinder cover 8 of the threshing apparatus 1 so that when the handle cover 8 is opened, the transfer guide guide 7 is integrated with the handle cylinder cover 8. , It is easy to perform maintenance management near the transfer portion between the vertical transport device 5 and the feed chain 6. Further, the grain stalks transporting the cutting section A are smoothly transported without being caught by the harvesting section A during the harvesting operation, and the handover guide guide 7 interferes with the maintenance management of the vertical transport device 5 of the cutting section A. The work becomes easy because it does not occur. According to the present invention, the handover guide 7 is used as a handle cylinder of the threshing apparatus 1 .
By providing the cover 8, the lifting support frame 2
