Description

[Detailed description of the invention] This invention relates to a lifting and conveying device for husk culm in a combine harvester. Specifically, the culm after harvesting is lifted and conveyed by an endless conveyor chain and a clamping rail to a foot chain of a threshing device. This is related to the structure of the clamping rail of the supplying shell culm lifting and conveying device, and on the transfer start end side of the shell culm, the resistance is reduced so that the shell culm is fed between the endless transport chain and the clamping rail, and clogging occurs. At the middle of the transfer, reliable clamping is obtained, and at the end of the transfer, the clamping force of the culm is slowly weakened and released, and the culm at the base of the plant is gradually laid down on its side so that it is placed on the foot chain. The purpose is to displace it and accurately hand over to the foot chain.

The present invention will be explained below based on one embodiment shown in the drawings. 1 has a reaping device 2 at the front lower part and a threshing device 3 at the rear.
This foot chain 4 is almost parallel to the direction of aircraft movement,
The aircraft is also equipped with the shell culm supply port located at the front.

Reference numeral 5 denotes a sugar part lifting and conveying device that engages the side part of the tip of the shell culm and lifts and conveys it, and 6 denotes a shell culm lifting and conveying device that lifts and conveys the stock part of the shell culm, These are arranged in two stages, upper and lower, so that the harvested husk is lifted up and transported to be supplied to the threshing device 3.

That is, the starting end of the culm lifting and transporting device 6 is located above the reaping device 2, the terminal end is located near the starting end of the foot chain 4 of the threshing device, and the terminal end of the sugar part lifting and transporting device 5 is visible above the shell culm supply port of the threshing device, and by arranging them in a V-shape when viewed from the top, the shell culm is taken over after harvesting and is lifted up and transported while being sequentially laid down from a standing position. It is configured to change its posture and supply it to the threshing device 3.

The sugar part lifting and conveying device 5 is composed of a conveying chain 5a with a conveying lug a and a guide rod 5b, and the lifting and conveying device 6 on the stock side mainly consists of an endless conveying cheno 7 and a clamping rail 8.
The support frame 9 of the endless chino 7 is fixed to one end of a U-shaped connecting fitting 10, and the other end of the U-shaped connecting metal fitting 10 is provided opposite to the endless chino 7 via a bullet 11. A clamping rail 8 is attached.

In addition, the shell culm lifting and conveying device 6 is configured such that its terminal end side (with the starting end side as the center of rotation) can be adjusted to move in the distance direction with respect to the foot chain 4 to change the position of holding the shell culm on the foot chain. It is configured so that it can be done.

The clamping rails 8 are formed by bending a single plate into a U-shaped cross section, and are disposed opposite to each other so as to sandwich the upper play 7a of the endless transporting chino 7.

That is, in the middle of the clamping rail 8 excluding the starting end and the terminal end, the upper side 8a, which has a U-shaped cross section as shown at the opening in FIG. 4, is located above the upper plate 7a of the endless chino 7, and the lower side 8b is the top and bottom play) 7a, ? The structure is such that the shell culm is reliably held and conveyed by being placed oppositely so as to be interposed between the two.

On the starting end side of the clamping rail 8, the upper side 8a is removed and only the lower side 8b is left, as shown in FIG. An upper side 8a is provided from near the end, and the bent length is gradually increased and inclined toward the direction of transport of the culm, and then the bent length is the same as that of the lower side 8b.

Further, on the terminal end side, contrary to the starting end side, the lower side 8b is formed to be sequentially shorter than the upper side 8a on the terminal side,
At the final end, as shown in FIG. 4C, the lower side 8b is completely removed and only the upper side 8a is positioned above the upper plate 7a.

Since the present invention is constructed as described above, if the machine is moved forward while operating a predetermined device, the culm will be harvested by the reaping device 2 and then transferred to the lifting and conveying devices 5 and 6. The culm is lifted up and transported, and before reaching the end of the transport, the posture of the culm is gradually changed from a standing state to a sideways tilted state, and the stock base is inherited by the foot chain 4 of the threshing device 3. The tip of the ear is fed into the threshing device 3 and subjected to the threshing process.

When the base of the harvested culm stock is taken over to the starting end of the lifting and conveying device 6, the upper side 8a of the clamping rail 8 becomes shorter at the starting end than the lower side 8b, and is completely cut off at the very starting end. Since the culm is initially guided and held only by the lower side 8b, and then the upper side 8a gradually begins to protrude, the culm is gradually bitten into the shell, and there is no extreme disturbance in the posture. Smooth catching action
The process is carried out well, and since the upper side 8a and the lower side 8b of the clamping rail strongly press against the endless chain 7 side in the middle of the conveyance, the culm is only pulled out and the culm is securely clamped and conveyed. However, when the end of the conveyance is reached, the lower side 8b of the clamping rail 8 becomes shorter than the upper side, so the stock base is returned to the direction along the tilted posture of the side part of the ear, and the bottom of the endless chino 7 is Since it tends to rise and separate from the side plate 7b, it is not carried around,
The handover to Feet Chain 4 will be carried out smoothly.

This idea is based on the fact that the upper plate of the endless conveyor 7 is sandwiched between an upper side 8a and a lower side 8b formed by bending a single plate, and has a U-shaped cross section. The clamping rail 8 has only a lower side 8b on the transport start end side, and has a curved configuration that moves away from the endless transporting chino 7, and an upper side 8a of the clamping rail 8 is provided from near the curved end to gradually increase the length of the lower side. The upper side 8a and the lower side 8b are aligned with approximately the same bending length at the intermediate portion of the conveyance, and the lower side 8b is aligned at the end portion.
Since the configuration of the husk culm lifting and conveying device for a combine is such that b is formed in an oblique shape so that it becomes sequentially shorter than the upper side 8a, the starting end of the husk culm lifting and conveying device that catches the harvested husk culm. In the transport section, the reaped husk culm, which is sent in a lump, is caught reliably with little resistance without bending, so that no clogging occurs, and in the intermediate section, the upper and lower sides of the clamping rail against the endless chain are fixed. By keeping the clamping force roughly the same and strong, it is possible to transfer accurately by preventing the culm from falling out. At the end of the transfer, the clamping force on the lower side is gradually weakened and the stock side is slowly moved to the tip side position. It is possible to smoothly change the posture without bending or breaking the shell culm by laying it on its side, and then lifting it up and transporting it, and it has the effect of being able to accurately transfer it to the foot chain.
