In addition, a cutting blade 21 is provided below the scraping cases 13a and 13b.
On the other hand, a drive pulley and a driven pulley are respectively arranged above the take-in cases 13a and 13b, and the take-in belts 20a and 20b having tines are wound around them. Further, the tip end of the tip transfer device 30 is located above the rear part of the scraping belt 20b on the right side in the traveling direction, and the rear end part thereof is arranged so as to be inclined upward. Also, the tip conveying device
As shown in FIG. 1 to FIG. 3, a sprocket 12 is disposed below the stock 30, and a stock carrier transport feed chain 5 is wound around the spike carrier transport device 30 substantially in parallel therewith. .

A spring case 9 is provided on the side of the feed chain 5, and four bars 8 project from the case 9 toward the feed chain 5. A front rod-shaped guide 6 is fixed to the tips of the two bars on the upstream side of the feed chain 5, and a rear rod-shaped guide 7 is fixed to the tips of the two bars on the downstream side. On the other hand, in the spring case 9, each bar 8 has a compression spring 11
... are attached, and by the action of these compression springs, the rod-shaped guides 6 and 7 are elastically pressed between the left and right plates of the feed chain 5, which extend in a substantially straight line, as shown in FIG. 1 (b). Has been done. And the first
As shown in FIG. 6A, the starting end of the front rod-shaped guide 6 is curved outward in an arc, and the starting end of the rear rod-shaped guide 7 is bent at an acute angle with respect to the feed chain 5.

Also, one end of a spring guide 10 is attached to the upper end of the spring case 9, and the other end of the spring guide 10 is, as shown in FIG. 6 and along the lower surface of the rod-shaped guide 6 (right side in FIG. 1 (b)),
Then, in the vicinity of the boundary between the front rod-shaped guide 6 and the rear rod-shaped guide 7, elastic pressure is exerted between the plates of the feed chain 5.

Further, as shown in FIGS. 1 (a) and 2, one end of a linear spring 19 is attached to the upper center of the scraping case 13a, and the other end is attached to the feed chain 5a.
The plate is pressed between the plates at the upstream end of the. Also,
One ends of the linear springs 17 are attached to the tip end side portions of the scraping cases 13a and 13b, respectively, and the other ends are curved toward the tip end portion of the feed chain 5, respectively.

Since the present embodiment is configured as described above, when soybean cutting is performed, the soybean culm is scraped by the tines 16a, 16b of the scraping chains 13a, 13b located at the frontmost part of the machine body 1. , Is cut by the cutting blade 21. Then, the grain culm is guided to the feed chain 5 by the linear spring 17 and the linear spring 19. The guided grain culm is conveyed downstream while being sandwiched by the feed chain 5 and the rod-shaped guide 6. Between the terminal end of the forward rod-shaped guide 6 and the starting end of the rear rod-shaped guide 7, the grain culms are sandwiched between the feed chain 5 and the spring guide 10 and conveyed. Further, the grain culms are sandwiched by the feed chain 5 and the rear rod-shaped guide 7 and conveyed to the pea removal machine behind the machine body 1. At this time, the soybean tips are conveyed by the tip conveying device 30 that cooperates with the feed chain.

Thus, when cutting soybeans, the grain culms are guided by the linear spring guides 17 and 19 so that they are smoothly guided to the stock feed carrier feed chain 5. In this case, since the starting end of the front rod-shaped guide 6 is curved outward and curved, the grain culm is not caught on the starting end of the front rod-shaped guide 6. In addition, since the rod-shaped guide which is conventionally configured by one is divided into two, the overall length of the rod-shaped guide 6 can be shortened, and even when the grain culms are intermittently fed, the opening of the mouth is increased. Can be made smaller.
Further, even if the starting end of the guide 6 is slightly opened, the grain culm is held by the feed chain 5 and the linear spring guide 19, so that the grain culm is prevented from being dripped and spilled. Can be achieved.

Also, between the front rod-shaped guide 6 and the rear rod-shaped guide 7, since the spring guide 10 is elastically pressed by the feed chain 5 in the vicinity thereof, the grain culm can be smoothly transferred between both guides. Since the spring guide 10 is elastically pressed across the rod-shaped guides 6 between the chain plates of the feed chain 5, even if a large amount of grain culms pass at a time and the spring guide 10 floats above the plate, There is little risk of the plate coming off the projection, and even if it does come off, it immediately returns to the fixed position and can properly and properly serve as a conveyance guide.

In addition, even at the starting end of the rear rod-shaped guide 7 located on the downstream side of the feed chain 5, the starting end is bent at an acute angle with respect to the feed chain 5, so the grain culm from the spring guide 10 to the rear rod-shaped guide 7 Even when delivering
There is no risk that the grain culm will be caught at the starting end of the rod-shaped guide 7.
Further, since the rear rod-shaped guide 7 is also configured to have a short overall length, both the starting end portion and the terminating end portion thereof are the feed chain 5
Since there is little opening between the culm and the grain culm, it is possible to prevent only grain culm from being conveyed, spillage of culm and the like to be prevented, and the grain culm can be smoothly conveyed to the rear by the cooperation of the tip conveying device 30.

(G) Effect of the Invention As described above, according to the present invention, the rod-shaped guides (6) and (7) that are elastically pressed against the transport feed chain (5) are divided into a plurality of pieces so that the entire length of one rod-shaped guide is increased. Since they are shortened and arranged side by side on a straight line, bar-shaped guides (6), (7) by the grain culms in the middle of transportation even when the grain culms are intermittently transported
It is possible to reduce the mouth opening at the start end or the end of the spring, and the spring guide 10 is arranged in the vicinity of the adjacent rod-shaped guides (6) and (7) so as to elastically press the feed chain (5). Therefore, the grain culm can be smoothly transported between both guides, and the grain culm transport can be prevented from dripping and culling.
