DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a culm conveying means for a self-removing combine equipped with a full-throwing-in device for introducing the whole cut short culm into a threshing unit.

[0002]

2. Description of the Related Art A plurality of rails are supported on a rail base via rail pins, and the front side of the rail base is divided so as to be rotatable. The front part of the rail base is rotated upward. Japanese Patent Application Laid-Open No. 55-19019 discloses a full-loading device in which a rail base and a rail are integrally retracted upward from a feed chain provided below.

[0003]

Normally, a cover for protecting the rail base and the rail is mounted above the rail base. However, the one disclosed in Japanese Patent Application Laid-Open No. 55-19019 largely retracts the rail base and the rail upward. Therefore, a cover cannot be provided. Further, a complicated and long cover is required to provide the cover. Also, since the rail base is divided so as to rotate on the front side, rattling may occur at the rotation position of the rail base when conveying the grain culm, or the front portion of the rail base may be pressed by the grain squeezing pressure. Due to being pushed up, the grain stalk clamping force between the rail and the feed chain cannot be maintained properly. In addition, since the rail base is rotatable, the structure for attaching the rotating portion of the rail base to the machine body in the nipping and transporting state becomes complicated. In addition, the rail itself has a rotating part on the front side and
Since the fixed part is separated, it can be
Rails do not move up and down in conjunction with each other.
Problems such as step differences in the stalks and the transport of grain stalks are disturbed.
There is a title.

One end of the wire 63 is connected to the wires 32 and 40. When the shift lever 43 does not come into contact with the cam plate 46, that is, when the shift lever 43 does not shift to the high speed side, the slide guide plate 55 and the wire 5
1 and the cam plate 46 are pulled, the cam plate 46 comes into contact with the stopper pin 49, and the shift lever 43 shifts to the high speed side to rotate the cam plate 46, so that the wire 51 and the slide guide plate 55 Is pulled and moves,
The full-amount feeding lever 60 abutting on the opening 55a of the slide guide plate 55 is rotated so that the return spring 59 is extended.

That is, the speed change lever 43 is moved to the low speed position 45b.
, The full-load lever 60 is returned and the spring 5
9, the wires 63 and 32 are pulled and the cam 30 connected to the link moving lever 29 is pulled.
Is rotated, the connecting plate 27 moves upward, and the rail pins 2
The links 22, 22 connected to the feed chains 6, 26 are lifted to a position away from the feed chain 9, and a gap is formed between the feed chain 9 and the links 22, 22. At the same time, the wires 63 and 40 are also pulled, and the stalk guide 3
6 rotates upward, and the rail pin 2 of the feed chain 9 is rotated.
The projections at the 6th and 26th portions are hidden in side view. For this reason, the grain squeezing force and the conveying force of the feed chain 9 and the rail 25 are lost, and the grain stalks nipped and conveyed between the feed chain 9 and the foremost part of the rail 25 are pulled out by the entire handling cylinder 2. Since all of the grains, straws and the like are agitated and processed in the handling room 6, the unhandled amount can be significantly reduced. At this time, the full-amount feeding lever 60 is positioned at a position slightly beyond the conceivable point.
And is stably held at this position.

When the shift lever 43 is shifted to the high speed side by the low speed position 45b, the cam plate 46 is rotated, the wire 51 and the slide guide plate 55 are pulled, and the wire 51 and the slide guide plate 55 come into contact with the opening hole 55a of the slide guide plate 55. The full-amount input lever 60 is tilted toward the pin 56 and is turned off. As a result, the wires 63 and 32 are loosened, so that the cam 30 connected to the link moving lever 29 is turned to the horizontal position, the connecting plate 27 is moved downward, and the rail pins 26 and 26 are moved.
The lower ends of the links 22 connected to the feed chain 9
And the gap between the feed chain 9 and the links 22 is eliminated. At the same time, wire 6
Since the grains 40 are loosened, the grain guide 36 rotates downward by its own weight and abuts against the stopper pin 42, so that the projections of the rail pins 26 of the feed chain 9 can be seen in a side view. For this reason, the grain culm holding force and the conveying force of the feed chain 9 and the rail 25 are restored, the total amount is automatically released, and the grain culm held and conveyed between the feed chain 9 and the rail 25 is handled in the handling room. At 6, the husks that have been threshed and after threshing have passed through the handling room 6 by the feed chain 9 and are delivered to the waste straw feed chain 11. As a result, if the efficiency is increased by feeding the whole grain culm, the processing capacity of the handling room 6 is exceeded and the handling room is damaged or broken down. However, such a decrease can be avoided. In addition, when the shift lever 43 is on the high-speed side, the full load is automatically released, so that erroneous operation does not occur. Further, since the full-amount input lever 60 corresponds to the driver's seat, it is possible to switch over to the full-amount input at hand, which is extremely simple and can immediately cope with a harvesting situation. Also, feed chain 9
Since there is a pinching / transporting capacity between the leading end of the hull and the rail 25, there is no backlash at the threshing entrance, and the whole amount of cereal stem can be quickly and reliably introduced.

[0015] Based on the above configuration, the reaper culms when the poor short or when ear set is the total amount closing lever vertically to a support member A which is fixed to the machine body when the state of the incoming (the work motion means) 60 a plurality of rail pin 2 which slidably inserted into
The 6 and 26, the link moves the hand stage 2 4, by pulling upward against the elastic force of the rail spring (elastic member) 21 provided between the support member A and the link 22, a rail pin 26 A plurality of linked continuous links 22 are also pulled up. When the harvested culm is long, the rail pin 26 is urged downward by the elastic force of the rail spring (elastic member) 21 provided between the support member A and the link 22. That is, by moving only the links 22 and 22 in the vertical direction, the rail 2
5 can be switched between the fully loaded state and the nipping and conveying state.

Further, in this embodiment, the function of the whole amount feeding device can be sufficiently exhibited even without the grain stalk guide 36, so that the whole amount feeding device without the grain stalk guide 36 can be provided. Further, the present embodiment can be applied so that when the grain culm or the short culm lays down, it is detected by the handling depth sensor, and the full-batch input function is activated in conjunction with the signal.
