Description

[Detailed Description of the Invention] The present invention relates to a combine harvester that binds the tip side of straw from a threshing machine and discharges it in an upright position.

Conventionally, when this kind of combine harvester discharges waste straw, the tied waste straw and the unbound subsequent waste straw become intertwined on the stock side, and when the tied straw is released, the subsequent waste straw is pulled out, and the subsequent waste straw is Not only does this disturb the posture and make the next bundling defective, but the base side of the bundling base also becomes disorganized, making it unreliable to leave it in an upright position in the field with the base facing down.

The object of the present invention is to provide a combine harvester that can eliminate the drawbacks caused by such disturbances on the stock side, and can achieve good cohesion of the ears and ensure reliable standing position.

The combine harvester of the present invention has a first conveyance path in which the tip side of the bundling base is clamped from the tip bundling device of the straw discharger, and the conveyance direction is set so as to move away from the straw in the bundling device while facing toward the stock side. and a second conveyance path that suspends and conveys the ears from the end of the first conveyance path toward a predetermined discharge and fall point while holding the tips in place. It has the following effects.

In other words, since the binding group is conveyed by the first conveyance path so as to rotate around the stock base side of the subsequent unbound group, the entanglement of the stock base is removed without dragging out the unbound group, and the untied base is removed. The binding base can be separated without disturbing the posture of the binding base, and since the separated binding base is suspended and transported in the second conveyance path, the base side of the stock is protected from its own weight and vibrations during transport. , it hangs down correctly, and when the whole body is in a substantially conical standing position, it is dropped when it is suitable, and it can now be left in a standing position reliably.

Next, embodiments of the present invention will be described.

A combine harvester in which a threshing device 2 is mounted with the handling trunk shaft 1 directed in the front-rear direction of the machine body, and the rear portion thereof is used as a straw discharge section 3 will be described as an example.

The waste straw is fed into the waste straw discharge section 3 in a sideways posture by the feed chain 4, and the waste straw is transported diagonally backward from the end of the feed chain 4 toward the tip side of the waste straw by the waste straw conveying device 5. More will be sent.

A tip-side binding device 6 is disposed below the terminal end of this straw removal conveying device 5.

Then, a first starting end sprocket 7 is arranged near the discharge port of the bundling device 6, and a first ending sprocket 8 is arranged above the first starting end sprocket 7 and at the base of the straw stock, A first endless chain 9 with protrusions is wound around both of them, and a first clamping rail 10 is pressed on the upper side of this chain 9, and a first
The conveyance path 11 is the same.

Further, a second starting end sprocket 12 is arranged with an inclined axis in the immediate vicinity of the first end sprocket 8, and is located near the front of the machine body and near the side of the machine body on the uncut side with respect to the second starting end sprocket 12. A second end sprocket 13 is provided, a second endless chain 14 with protrusions is wound around both sprockets 12 and 13, a second clamping rail 15 is pressed against the rear side of this chain 14, and this rail 15 and chain 14 are A second conveyance path 16 is defined between the two.

The conveyance device 17 is configured in this manner.

The first start/end sprocket 7.8 and the second rail 15, as well as the second start/end sprocket 12.13 and the second rail 15, are each integrally assembled in a frame 18.19. Both frames 18, 19 are fixedly connected near the end of the first path 11.

In this way, the tied bundle is transported by the first transport path 11 so as to rotate approximately around the stock side of the unbound waste straw,
The separated and untied waste straw is prevented from being disturbed in its posture, and the tied bundle separated from the untied waste straw is suspended and conveyed to the release position by the second conveyance path 16, and the tied bundle is placed in an upright position at a predetermined position. He is trying to leave it alone.

Reference numeral 20 denotes a power transmission structure to the bundle discharging device, in which power is transmitted from the output shaft 21 of the threshing device 2 to a first shaft 23 via a belt transmission device 22, and from this first shaft 23 to a gear 24.2.
4' transmits power to the second shaft 25, and the intermediate portion of the second shaft 25 is thrust into the mission case 26 of the binding device 6 to serve as an input shaft of the binding device 6.

A third shaft 27 is connected to the tip of the second shaft 25 via a bevel gear 28° 28', and the third shaft 27 is
The terminal sprocket 13 is pivotally supported.

The second start end sprocket 12 of the second conveyance path 16 and the first end sprocket 8 of the first conveyance path 11 (7) are interlocked and connected by a universal 30.

31 is a knot portion of the binding device 6; 32 is a string supply portion; 3
3 is the cohesion space.

In addition, in the present invention, the rotational axes of the second sprocket 12 and 13 may be made vertical.

Alternatively, the rotation axis of the first sprocket 7.8 may be made horizontal.

In addition, by using an endless chain whose conveying surface is not only on the outside of the direction but also on its side, the first and second conveying paths 11 and 16 can be constructed by a series of endless chains. It is something.
