わせて設けている。The connecting rod 52 comprises two rotating arms 52a and a lot 52b connecting them. Next, as shown in FIGS. 3, 5, and 11, the front inheritance chain 9 and the auxiliary succession chain 10 are provided with anti-winding plates 21 and 22, respectively, at least close to the left and right sides of the transport end portion. . And the winding prevention plate 2
In the case of the embodiment shown in FIG. 11, 1, 22 have a configuration in which the upper portion is bent inward (toward the chain side) to narrow the gap with the chain and to prevent the intrusion of straw waste. The upper edge is provided along the height of the valley of the chain plate.

の落下も少ないものとなっている。As shown in FIGS. 12 and 13, the anti-winding plate 21 extends from the end of the front succession chain 9 to the feed chain 8 side to guide the grain culm and facilitate the succession. It has a configuration that can assist. In this case, the wrap prevention plate 21 is particularly configured to extend the outer prevention plate toward the feed chain 8 side so that the grain culm can be inherited accurately, and that the swarf and the like are prevented from falling down. I have to. As shown in FIG. 12, when the front inheritance chain 9 and the auxiliary succession chain 10 rotate up and down in conjunction with the up-and-down elevating operation of the pre-cutting device 11, the wrap prevention plate 21 rotates as described above. In the lowered position (although the distance from the feed chain 8 is relatively wide), the upper edge 21a and the transfer line in the valley portion of the feed chain 8 are aligned on the same plane, and as shown in FIG. The end 21b and the start of the feed chain 8 move to a position where they approach each other. Therefore, regardless of the vertical movement of the front succession chain 9, the transported grain culm is always properly inherited by the feed chain 8, and the fall of straw chips and the like is small.

As shown in FIG. 14, 52 is provided along the arc shape at the tip of the front succession chain 9, but is provided inside the trough of the chain at that portion. Therefore, even if the front succession chain 9 is turned up and down in conjunction with the pre-cutting device 11 as described above, the front end portion always has the front end cover 5.
Since it is located outside of 2, it can properly act on the succeeding grain culm and have a scraping action.

Start the engine and operate the mowing clutch and threshing clutch to transmit the rotating parts of the fuselage.
5, and the harvesting and threshing operation by the combine 23 is started. Then, the grain culm in the field, as shown in FIG.
Weeding action is caused by the weeding rod 29 at the lower part of the front end, and then the culm raising device 30 raises the plant from the lying state to the upright state by the raising action of the culm raising device 30. It is squeezed by the action of the wheel body 32a and the endless endless band 32b, and the stock chain 1 and the tip carrier 3
1, and are conveyed sequentially and upward to the rear.

継ぎを促進し、稈こぼれを防止するものである。As described above, the combine 23 continuously performs the harvesting and threshing operation, harvests the threshing-selected kernels, and collects and stores them in the Glen tank. During such a continuous operation, the U-shaped connecting member 20 of the handling depth adjusting device 33 is used.
Is formed to have a minimum necessary short length, so that the seeds of the cereal stalk passing through the inner transport passage 19 scrape out the straw waste to be caught in the transport direction so that there is no straw waste pool. Is kept. When the guide rod 5 at the end of the handling depth adjusting chain 2 is separated from the end of the handling depth adjusting chain 2 when the upper part of the transported grain stalk is inherited by the subsequent supply adjusting chain 3 and It regulates the root of the strain from the outside and acts as an inducer. At this time, the guide rod 5
Is transported in a sandwiched state to the end of the handling depth adjusting chain 2 and acts to press against the cereal stalks that are open and swell outward, thereby preventing expansion, guiding and smooth inheritance. Promotes stalks and prevents spills.

れもなく確実に受継がれる。The culm reaching the end of the supply adjusting chain 3 is pushed up from below by the stock guide rod 15 extending from the lower side to the front inheriting chain 9 side at the rear of the holding rod 37. As a result, it is guided to the lower side of the culm guide rods 12 and 13 by being sandwiched by the upper guide guide rod 16, and is inherited by the start end of the front inheritance chain 9. In this way, the cereal culm is reliably inherited from the supply adjusting chain 3 to the inheriting chains 9 and 10 without any spilling in a stable state by the cooperative action of the stock guide rod 15 and the guide rod 16.

At that time, at that time, the anti-winding plates 21 and 22
Respectively function to prevent winding of the grain stalk beforehand and to transport it properly. In the middle of such a work, even if the front succession chain 9 and the auxiliary succession chain 10 turn up and down in conjunction with the cutting height adjustment operation of the cutting pre-processing device 11, the winding prevention plates 21 and 22 can be moved. 12 and 13 with respect to the feed chain 8, the culm can be reliably inherited. At this time, since the distal end cover 52 is retracted from the arc portion at the start end of the front succession chain 9 as viewed from the side as shown in FIG. 9 acts directly on the succeeding grain culm and rakes it in, so that the succession can be improved.

Further, the transported grain culm can be smoothly inherited and supplied from the supply adjusting chain 3 to the inherited chains 9 and 10 without spilling. The handling depth adjusting chain 2 and the holding rod 6
The U-shaped connecting member 20 that supports the above has the advantages that it can be made compact to the minimum necessary size to make it lightweight and low-cost, and that the straw can be prevented from being caught. Further, the present invention is characterized in that the grain culm can be prevented from being wound around each of the inherited chains 9, 10 so that the grain culm can be properly inherited and conveyed.
