Description

[Detailed description of the invention] Conventionally, a guide rod attached to the end of a grain conveyor for transporting harvested grain culms is connected to the feed chain of a threshing device and the feed chain of a threshing device, and the starting end of a peg rail with a U-shaped cross section along the conveyance surface. When the guide rod is pressed against the grain culm at a position in front of the pinning rail at the start of work, the combine harvester inserted between the two rises while being displaced toward the stock base, as shown by symbol a in Figure 4. As a result, there was a gap a' between the guide rod and the feed chain that did not hold the grain culm, which caused the grain culm to fall out during inheritance.

Also, when the pre-processing device or the grain culm conveyor is swung up and down, the guide rod moves forward and backward relative to the pinning rail, and when the pre-processing device, etc. is raised and the guide rod enters, the pinning rail is raised and lowered. There was a drawback that it collided with the holder and pin used to hold it freely.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the purpose of the present invention is to connect the end of the stock carrier of the pre-processing device to a clamping rail that straddles the feed chain of the threshing device and the chain plate on the handling room side. A combine harvester in which a guide rod, which faces between the starting ends and is provided at the terminal end of the stock conveyor, is inserted between the feed chain and the clamping rail, and is configured to swing vertically around the rear of the pre-processing device, The inner upper part of the clamping rail is provided with a guide plate which expands downward and has both lower edges in contact with the hanging part of the clamping rail, so as to cover the tip of the guide rod. be.

The embodiment shown in the drawings will be explained below.1
is a threshing device mounted on a machine base 3 having a traveling device 2, and a pre-processing device A that swings up and down about a horizontal shaft 4 is installed in front of the threshing device. It is composed of a culm pulling body 5 . oscillate.

Further, a vertical shaft 14 that supports and drives the ear side conveyor 8 and the stock head conveyor 9 is connected to a gear case 15.
Since it is interlocked and connected to the horizontal shaft 4 via
When the handling depth adjustment lever 16 is tilted back and forth, the ear side conveyor 8 and stock head conveyor 9 are vertically swung to adjust the handling depth.

Furthermore, the front part of the feed chain 17 stretched along the handling opening of the threshing device 1 is inclined upward in the conveying direction as shown in FIG. has a downward U-shaped cross section, straddles the chain plate 17'' on the handling room side of the threshing device 1, and has a lifting rod 19 at the upper part of the part where the grain culm is sandwiched and at the rail joint on the lower side thereof. A holder 21 is attached to support the lift rod 19 with a pin 20, and the lifting rod 19 is attached to a support frame 22 via a bullet 23 and a stop pin 24 so as to be able to move up and down.

The front end of an elastic guide rod 25 is attached to the rear part of the clamping rail holding part of the stock base conveyor 9, and the intermediate part thereof is aligned with the ascending slope part 17a at the starting end of the feed chain 17, and the rear end is It is inserted between the feed chain 17 and the clamping rail 18.

Moreover, inside the part of the clamping rail 18 that starts the clamping relationship with the feed chain 17, there is a guide plate 2 consisting of a top part b and inclined parts c and d that are widened at the bottom.
6 are welded e, e, and the top part b is attached to the pin 20.
and close to the lower edge 21' of the holder 21.

Next, to explain the operation, the harvested grain culm is transported backward by the stock head conveyor 9 and the ear side transport body 8, the ears are inserted into the supply port through the entrance plate, and the stock head is inserted into the guide rod 25. Feed chain 17 while being guided
transferred onto the ascending slope part 17a of the
Finally, it is sandwiched between the feed chain 17 and the starting end of the clamping rail 18, and is transported while being clamped.

When the grain culms are first transferred to the transfer section constituted by the guide rod 25 and the ascending slope, the guide rod 25 is pushed up, but the rear part of the guide rod 25 is located at the slope d of the guide plate 26. As shown in FIG. 3, the guide rod 25 moves toward the tip of the grain as shown by the arrow in FIG. 4 and rises as shown in FIG. can be securely held and transferred.

Also, when the pretreatment device A is raised, or when the stock head conveyor 9 and the ear side conveyor 8 are swung upward to reduce the handling depth, the rear part of the guide rod 25 moves backward. A pin 20 and a lower edge 2 of a holder 21 are inserted to bendably support the clamping rail 18.
1', but since the rear part of the guide rod 25 is prevented from rising by the top of the guide plate 26, no collision occurs.

Since the present invention is configured as described above, when the grain culm is transferred from the stock carrier to the feed chain, the guide rod is pushed up and raised by the grain culm riding on the starting end of the feed chain. The terminal end is guided by the slope of the guide plate installed in the pincer rail and moves upwards toward the higher tip of the grain, preventing the gap between the guide rod and the feed chain from opening abnormally and allowing the grain culm to grow. can be prevented from falling off during transfer.

In addition, when the pre-processing section is raised or the stock base conveyor is tilted to adjust the handling depth, the guide rod is inserted largely between the feed chain and the clamping rail, and the guide rod is inserted between the feed chain and the clamping rail on the downstream side in the transport direction. Although the guide rod is likely to collide with the lower edge and pin of the holder that supports the bent portion of the rail, the rear part of the guide rod is prevented from rising by the guide plate, so the collision does not occur.
