Thus, the clamping force is stabilized in all the processes of clamping conveyance.

  Next, as shown in FIG. 3 and FIG. 4, it has already been described that the merging grain conveying device 4 is composed of the root chain 22 and the tip conveying lug 23, but in the configuration of the example, The guide plate 28 that guides the upper part of the cereals is arranged on the rear side along the conveyance path of the cereals from the upper side of the tip conveying lug 23, and is guided with the upper part of the conveyed cereals placed thereon. It is configured as possible. And as shown in FIG.3 and FIG.4, the upper tip conveyance lugs 30a and 30b are divided | segmented into the front part and rear part of a conveyance path in the upper position of the said tip conveyance lug 23, and are arrange | positioned from the front side. The upper part of the cereal is conveyed while being guided on the guide plate 28 while protruding the lug toward the rear side. In this case, the upper tip transport lug 30a is in a position that smoothly conveys and guides the upper part of the rightmost two harvested cereal grains, and one upper tip transport lug 30b has one row of harvested grain ridges adjacent to the left. It is configured to be arranged at the position to be joined and transported, so that the cereal merging is facilitated. Further, as shown in the side sectional view of FIG. 4, the characteristic configuration is that while maintaining the angle close to a right angle with respect to the plate surface of the guide plate 28 arranged on the opposite side, the one upper tip conveyance lug 30b.

It is also possible to transport in a posture, and the upper tip is also used when the conjugation cereal transporting device 4 is bent to a shape close to a letter shape in plan view at a portion reaching the left side of the driver's seat 8. There exists an advantage which can be comprised without affecting the conveyance lug 30b.

  Then, as already explained based on FIG. 1 to FIG. 4, the conjugating culm conveying device 4 has the conveying start end portion of the root chain 22 positioned on the right side of the reaping device 2, and the right chain 24. It is located on the upper side, connected, and provided at a position to take over the two harvested cereal grains. And as shown in the drawing, the root chain 22 constituting the merging grain feeder 4 extends obliquely rearward, and conveys the cereals from the front side in the middle of conveyance while conveying them upward in the rear part of the vehicle body 3. Thus, it is set as the structure which inclined further toward the left from the center. As shown in FIG. 1 or FIG. 2, the root chain 22 is located at the lower side position in the transport direction from the root chain 7 a of the right transport device 7, and at the front position from the middle transport device 6, the non-transport side at the rear side. Therefore, the pressing roller 25 is pressed against the front side and bent to a shape close to a hemispherical shape.

Next, although there is a part which overlaps with the structure already demonstrated, an Example is described about conveyance of a grain spike part.
First, the conveying device of the grain spikelet part, that is, the tip lug, especially at the conveyance start end part, the inheritance position of the upper part of the grain straw in relation to the raising action of the grain raising device 21 described later. It becomes important for smooth transport in Then, as in the embodiment, the multi-row cutting harvesting and conveying apparatus 1 is a relationship between the raising end portion (upper part) of the grain raising apparatus 21 on the left side in the traveling direction and the subsequent grain raising apparatus (upper part of the rice straw). Location is a challenge.

  In the embodiment shown in FIG. 3, the leftmost cereal carrying device 5 cuts the two rows of cereal ridges, and then collectively conveys them to the merging cereal carrying device 4. A first stage tip lug 31 having a long transport process is disposed above the second stage tip lug 31, and a second stage tip lug 32 having a shorter transport process is disposed further above. Then, as shown in the drawing, the intermediate transfer device 6 has a two-stage transfer configuration with a relatively long tip lug 33 above the root chain 6a and a short tip lug 34 above it along the transfer path.

  By constructing in this way, the multi-row cutting harvesting and conveying apparatus 1 reliably conveys the grain panicle portions of the two left-side conveying apparatuses 5 and 6 that respectively convey the two rows of grain ridges. It is possible. That is, the tip lugs 31, 32, 33, and 34 can prevent the poor inheritance (uptake of the tip portion) of the top of the cereal from the device 21 and perform smooth inheritance conveyance. It is supposed to be possible.

  Then, as shown in FIG. 3 and already described, the cutting and conveying apparatus 1 has a configuration in which the upper three tip conveying lugs 30a and 30b are configured in a single stage to convey the tip portion as described above.
