Description

[Detailed description of the invention] This invention improves the transfer posture of the husk from the reaping conveyance device to the husk culm transfer device, and the foot of the husk culm transfer device is designed to ensure and smoothly supply the husk to the threshing device. The chain is protruded forward from the front side plate of the threshing part, and at least the terminal end of the stock transfer device is located within the body width of the threshing device, so that the foot chain is located closer to the culm supply port than the starting end of the foot chain. The present invention relates to a reaping and threshing machine which is arranged in an inclined plane so as to approach the ground, and has a bullet pushing body extending from the upper surface of the starting end of the foot chain.

In conventional general combine harvesters, the end of the foot chain and stock transfer device is often installed at the joint part with the end of the stock transfer device projecting outward from the foot chain. In this case, since the culm during transfer is pulled out toward the foot chain by the stock transfer device, the stock part of the culm becomes uneven due to the pulling, and the tip of the culm may become entangled due to the action during the movement. It had drawbacks.

In addition, in order to reliably and smoothly supply and guide the culm,
There are already products equipped with culm guide rods, such as in Publication No. 826, but according to this publication, the amount of culm has decreased, although this is not a problem when a large amount of culm is flowing one after another. In this case, the culm will fall off at the foot chain starting end joint.

Therefore, the present invention has the above-mentioned structure to bring the stock part of the husk being transferred closer to the foot chain side, and by extending the bullet pushing body, it changes the direction of transfer from the tip conveyance. The base of the culm is flipped up, and a bullet pusher is used to scrape it onto the upper surface of the foot chain.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the combine harvester, in which a shell culm transfer device consisting of a foot chain 5 and a lever 8 parallel to the traveling direction of the machine is mounted on one side of the threshing device 4 mounted on the traveling chassis of the traveling device 7. The threshing device 4 is provided with a feeding port 9 on one side and a fourth port on the other side of the threshing device 4, in which the starting end of the foot chain 5 is arranged to protrude from the front side plate of the threshing section, and a cutter 10 is installed behind the threshing device 4. A reaping conveyance section is installed at the front of the machine so as to be connected to the threshing device 4.

In the reaping conveyance section, the cutting body 11 and the culm lifting device 12 are equipped at the frontmost part, and the roots of the grain culms are moved from above the reaping section 1 provided at the rear lower part toward the supply port 9 side of the threshing device 4. A stock head conveying device 3 for pinching and conveying the grain culm side is installed obliquely, and above it, a head tip conveying device 2 and a clamping rod 2 for pinching and conveying the tip side of the grain culm are installed obliquely and extending toward the front of the supply port 9.

Further, an auxiliary conveyor 3 is provided above the upper end of the stock conveyor 3 to feed the root side of the culm to the foot chain 5, and the end of the auxiliary conveyor 3' is threshed. A support is provided within the width of the fuselage, extends from the starting end of the foot chain 5 to the shell culm supply port 9 side and approaches the foot chain 5 in an inclined plane, and is fixed to the fuselage via a support pipe 13. A clamping rod 15 facing the auxiliary conveyance body 3' is attached to the metal 14, and a gripping guide rod 16 with one end fixed to the support body 14 is attached to a foot projecting from the front of the auxiliary conveyance body 3' toward the front side of the supply port 9. It extends above the chain 5 part and extends to the front of the gripping rod 8, and the port 1 is attached to the top of the support bar 14.
7 fixes one end of the long wide plate bullet presser body 6,
The ammunition pusher body 6 is extended along the gripping guide rod 16, and extended from above the foot chain 5 portion at the protruding tip up to a certain distance along the longitudinal upper surface of the foot chain so as to contact the chain pin 5'. 6' is a free end, and the base side of the shell culm is pressed from above by a bullet pushing body 6 and is brought into contact with the protruding tip of the foot chain 5.

Grain culms cut by the reaping unit 1 during the combine harvesting operation are conveyed by the stock head conveying device 3 on the root side and by the peg holding rod 2' on the ear tip conveying device 2, respectively, and transferred to the threshing device 4 side. Ru.

At the point where the root side is transferred from the plant base conveyance device 3 to the auxiliary conveyance body 3' and further conveyed by the clamping rod 15 while changing direction, the root side is transferred to the foot chain 5, slightly closer to the tip of the head than the ch 75. The strand is clamped by the auxiliary conveyor 3', and is further sandwiched between the foot chain 5 and the gripping rod 8 so that it comes off the auxiliary conveyor 3' and engages the foot chain 5 while being held and guided by the gripping guide rod 16. During this state, the root side of the culm is strongly pressed and guided by the bullet pushing body 6 with its wide surface against the upper surface side of the foot chain 5, and at the same time, the root side of the culm is guided by the upper surface side of the foot chain 5. is supplied to the supply port 9 away from the tip side of the upper conveyor 2 .

As described above, the present invention provides a culm gripping and transferring device parallel to the traveling direction of the machine on one side of the threshing device mounted on the traveling chassis with the foot chain facing downward, and a reaping device in front of the threshing device. In a configuration in which both the conveying devices for conveying the ear tip and the stock head are installed diagonally toward the shell culm supply port of the threshing device, the foot chain of the said shell culm clamping and transferring device is protruded forward from the side plate of the front part of the threshing device. At the same time, at least the terminal end of the stock transfer device is located within the width of the body of the threshing device, and is arranged in an inclined plane so as to be closer to the culm supply port than the starting end of the foot chain. At the same time, a bullet push body was extended on the upper surface of the starting end of the foot chain, so it was possible to extend it outward from the conventional foot chain to provide a pulling action, or to provide a culm gripping guide rod. In contrast, the base of the culm can be flipped upward by approaching the foot chain on the culm supply port side in an inclined plane and by simply extending the bullet pusher and slightly changing the direction of transport with respect to the tip conveyance. It is possible to transfer the grain to the upper surface of the foot chain by the pressure of the bullet pushing body, ensuring smooth conveyance without disturbing the conveying posture, and ensuring an orderly feeding posture to the threshing device with less entanglement between the husks and the like. It has remarkable effects such as being able to change direction.
