During the harvesting operation using a combine harvester, the culms in the field were pulled up by a pulling device as the five combine harvesters moved forward, and the root portion was cut off with a cutting blade, and the tip and root portions were transported by a tip and root conveying device. The grain is then threshed using the handling barrel of a threshing machine. In such harvesting operations, during threshing, if the tip of the shell culm does not reach the center of the handling barrel, unhandled portions may occur at the head of the ear, and if the tip of the husk does not reach the center of the handling barrel, and if the tip exceeds the center of the handling barrel, excess portions may be removed. The position of the tip of the ear during threshing is an important factor, as seed breakage occurs during handling. Conventionally, a feed adjustment device was installed in the reaper to move the shell culm being transported toward the grain store according to the length of the grain culm. It can be adjusted so that it is always located in the center of the handling cylinder regardless of the size.

However, in conventional combine harvesters, even if the supply is adjusted to the best of its ability, the result is often not satisfactory depending on the conditions of hoisting and conveyance.

In other words, when the culm in the field is raised using a device,
The culm stands up by pulling up the tip of the plant while the plant is held on the ground and being lifted up and carried by the lug, so the shorter the culm is, the faster the tip of the tip will be pulled up by the device. In the case of a short culm that is released and has high rigidity, it is released in a flipping state, so that the tip portion is captured by the conveying device faster than the root portion. Therefore, since the tip of the ear is conveyed first, if the tip and the root of the ear are simultaneously released from the conveying device at the end of conveyance and taken over to the threshing machine, the culm will be perpendicular to the axial direction of the handling barrel. There was a problem in that smooth threshing was not carried out, as the grain was fed at an angle and unhandled grain was generated. This is the same in the case of very long culms; if the culm is long, even after harvesting, the tip part will not be released from the lifting device, and the conveyance will be delayed compared to the root part. In the same way, unhandled parts occur with an inclination in the opposite direction.

The present invention has been made in view of the above points, and the lugs of the ear tip conveying device, which conveys the grain culm in an upright position and collapses at the end of the conveyance, are designed to collapse faster as the length of the conveyed grain culm becomes shorter. By making the lodging position adjustable, the inclination of the grain culm posture that occurs during raising due to the length of the culm is corrected at the end of the conveyance and fed to the threshing machine, preventing reaping and smoothing the threshing. The purpose of the present invention is to provide a combine harvester shell culm conveying device that is designed to reduce the Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

On the other hand, a tip conveying device (rear) 43 is mounted diagonally above the tip conveying device (front) 24 to convey the tip of the husk culm 11 taken over from now on toward the threshing machine 2. This conveying device 43 has a chain case 44 with ims facing the entrance of the threshing machine 2, and has a large number of lugs between a sprocket 45 at the upper end and a sprocket (not shown) at the lower end. Nine-point chain 4γ with 46 at regular intervals
is being strung up. Inside the chain case 44, a lug guide 48 is provided that spans almost the entire length of the lug guide 48, and as the tip chain 47 runs, the lug 46 stands up and runs by placing its base along the lug guide 48, and its tip travel trajectory. It is configured to hold and convey the tip portion of the grain culm 11 between it and the nine tip guide 49 which is supported along the ridge. Furthermore, a lug 46.

By doing this, when the piston rod 3T is extended, the 2-g lodging guide 5 is moved by the elastic force of the compression coil spring 53.
When the wire 52 moves toward the conveyance end side, the lodging of the lug 46 is delayed, and the piston rod 37 contracts, the wire 52 resists the elastic force of the compression coil spring 53 and moves to the lug guide 50 for lodging.
By moving the lug 46 toward the conveyance end side, the lug 46 is laid down more quickly.

As the machine moves forward, the grain culm 11 in the field is raked by the weeding body 12, and the tip part is conveyed to the hoist by the lug 18 of the raising device 14, and stands up from the K, and the root part is removed by the raking belt 21. After being transported, it is cut by the cutting blade I11. After the harvested grain culms 11 are raked by a raking device 22, the tip and root portions are transferred to a tip conveying device (front).
24 and the root conveyance device ff (moving) 2 s and are conveyed, and at the end of conveyance, the tip conveyance device (
) 43 and the supply conveyance device 29, respectively, and conveyed. Furthermore, the root portion of the culm 11 is connected to a root conveying device (
After) 40 is taken over and conveyed, but the supply conveyance device 29
The feed adjustment is carried out during the conveyance. That is, in the case of a long culm as shown by reference numeral 11A in FIG. 1, the piston rod 31 of the hydraulic cylinder 36 can be
When it is extended, the supply v4wJ device 29 transfers the free end side to the tip conveying device (rear) 43 via the lever 38 and rod 39.
While the culm 11m is being conveyed, it is pulled out toward the root, and the root conveying device (rear)
40, and then transferred to the feed chain 6, so that the tip of the grain culm 11A is located at the center of the handling barrel 4.In addition, the grain culm 11A is conveyed by the reference numeral 11B in FIG.
In the case of a short culm as shown in FIG.
As shown by the chain line in FIG. 1, the culm 11B approaches the (rear) ear conveying device 4'3 and moves toward the ear, so the threshing machine 2
When the short culm 11B is fed, the tip of the short culm 11B comes to the same attachment as the long culm 11A.

On the other hand, as described above, in the case of the long culm 11A, the tip is released from the pulling device 14 slowly and has low rigidity, so the capture of the tip after reaping is delayed compared to the capture of the root. Further, in the case of the short rod 11B, the tip is released from the pulling device 14 quickly, and due to its high rigidity, it is released and flipped from K at the end, so that the tip is captured faster than the root. Therefore, in the case of the long culm 11A, the root portion is transported first, and in the case of the short culm 11B, the tip portion is transported first. However, in this device, in the case of the long culm 11A, when the piston rod 31 of the hydraulic cylinder 36 is extended as described above, the lodging lug guide 50 connected to it by the width f52 moves toward the conveyance end side. By delaying the lodging position of the lug 46,
Even when the root of the long culm 11A is stopped for transfer to the feed chain 6, conveyance of the tip continues, so the delay in the tip is recovered, and the long culm 11A is placed in a posture perpendicular to the conveyance direction. is supplied to threshing machine 2. Also, short culm 1
1B, the piston rod 3 of the hydraulic cylinder 36
When T is contracted, the lodging lug guide 50 moves to the conveyance start end side, and the lodging position of the lug 46 is accelerated, so that the tip portion is quickly released from the holding and conveyance stops, and in the meantime, the delay at the root portion is recovered. Then, the short frame 11B is supplied to the threshing machine 2 in the same posture perpendicular to the conveying direction.

As is clear from the above explanation, according to the present invention, in the grain culm conveying device of a combine harvester, the lugs of the grain tip conveying device, which conveys the grain culm in an upright position and collapses at the end of the conveyance, have a shorter conveying grain culm length. By making it possible to adjust the lodging position t so that the grain lodges faster as the grain grows, the inclination of the grain culm posture caused by the length of the grain culm can be corrected at the end of the conveyance and then fed to the threshing machine. , mowing residue and ear breakage can be prevented, making threshing smoother.・
