DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a side view of a waste straw processing section at the rear of a combiner, and FIG. 2 shows a plan view thereof. In the drawing, reference numeral 3 denotes an upper-chain-type waste straw transporting device which inclines and transports the waste straw after threshing, which has been pinched and transported by the feed chain from the left-hand side of the drawing room to the rear and the tip side, in a sideways posture. A disk-shaped waste straw cutter 5 is a waste straw binding device.

The waste straw transporting device 3 comprises a transport chain 6 with projections and a transport rail 7 arranged below the transport chain 6, and the transport rail 7 further comprises a front rail 7a.
And a rear movable rail 7b which can be extended and contracted. According to this configuration, the waste straw can be shredded or bound by the expansion and contraction of the transport rail 7. That is, by shortening the rear movable rail 7b and setting the falling position of the waste straw to the front, the waste straw is supplied to the entrance of the waste straw cutter 4 opened by the upward swing of the guide cover 8, and By extending the movable rail 7b to switch the falling position of the waste straw backward, the waste straw can be supplied to the waste straw binding device 5 via the guide cover 8 which is swung downward and closes the cutter entrance. It is. Further, since the waste straw transporting device 3 is inclinedly transported, even in a state where the waste straw is supplied to the waste straw binding device 5, by appropriately expanding and contracting the rear movable rail 7 b, the end of the discharged straw is discharged. The binding position can be adjusted by changing the position to the left or right.

The discharging straw bundling device 5 is located above the focusing space S and supported by the upper frame 9.
0, and a lower case 12 positioned below the focusing space S and supported by the lower frame 11.
A needle 13 for supplying a tying string, a scraper circulating in a crank manner, and a scraper packer mechanism 1 for collecting a straw.
4 and a focusing pressure sensing door 15, and the lower case 12 includes a focusing deck 16 and a knot building 1.
7, a string holder 32, and a release arm (not shown). The knot building 17 and the string holder 32 are located on one side of the focusing space S, and the raking packer 23 for collecting the straws is disposed.
And the needle 13 are arranged on the other side, respectively.

A stock alignment plate 18 for striking the stock ends of the supplied straw is reciprocally swingable right and left about a front fulcrum P on the stock side of the stacker 5. It is arranged so that the position can be adjusted left and right.

As shown in FIGS. 2 and 3, the packer mechanism 14 includes a pair of left and right main packers 20 and 21 which operate at a position close to the left and right sides of the needle 13 to draw a tip circulation path A, and an upper case. A second packer 22 that operates by drawing a tip circulation locus B ahead of the tip circulation locus A on the stock side of the stocker 10 and a second packer 2
2 and an auxiliary packer 23 attached to the tip of the second packer.
The leading end trajectory B of the packer 22 and the leading end trajectory C of the auxiliary packer 23 (both corresponding to the circulating trajectory) are set so as to be sequentially shifted forward while slightly overlapping each other.

The main packers 20, 21 and the second packer 22 are connected to the base case of the first and second scraping arms 28A, 28B via the first and second swing arms 29A, 29B. 10 and the first and second crank arms 3 on the upper case 10 side at the middle in the longitudinal direction.
The free ends of the first and second raking arms 28A and 28B are pivotally connected to the free ends of the first and second raking arms 0A and 30B, respectively.

On the other hand, as shown in FIGS. 3 and 4, the auxiliary packer 23 is provided with first and second scraping members 34a and 34b made of separate members at the tip of the second scraping arm 28B. Then, the second scraping arm 28B, the second swing arm 29B, and the second crank arm 30B are shared with the second packer 20, and the first and second scraping bodies 34a,
The downward projection formed at the tip of 34b is configured as a scraping portion K3.

The first and second scraping bodies 34a, 34b
Are provided at both ends of the support shaft 24 which is fixed to the tip of the second scraping arm 28B in a transverse direction, and the first scraping body 34a is attached to the end of the support shaft 24 on the side corresponding to the base of the support shaft 24. And a second scraping member 34b is mounted on the end of the support shaft 24 on the side corresponding to the tip of the shaft so as to be position-adjustable. The second scraping body 34b is provided with a lock pin 26 that is biased by a spring 25, and is selectively engaged with a plurality of lock holes 27 formed in the support shaft 24 in the left-right direction. Can be fixed at a plurality of positions (four positions in the embodiment).

With the above configuration, for example, when the waste straw is extremely long, the second scraping body 34b is adjusted to be closest to the base of the stock, so that the scraping action of the second scraping body 34b is weakened, and the draining action is reduced. It is possible to prevent the straw from being quickly pulled out of the waste straw transporting device 3. When the straw is extremely short so that the first raked body 34a does not act, the second raked body 34b is adjusted to the ear tip side to adjust the second raked body 34b.
This ensures that the waste straw is scraped backward, thereby preventing the waste straw discharged obliquely from the waste straw transporting device 3 from approaching to the tip due to the release force. For the intermediate culm length between the extremely long culm and the extremely short culm, the second scraped body 34b may be selected at any position within the adjustment range.

As shown in FIGS. 4 and 5, on the inner side wall of the second scraping arm 28B, a second swing arm 29B is pivotally supported.
The connected base end side connection point E and the second crank arm 30B
Is connected to the intermediate connection point D, which is pivotally connected .
An L-shaped scraper member 31 is provided in a side view, which scrapes out a waste stirrer around the base end of the second crank arm 30B as the crank arm 30B rotates around the drive shaft center P1 . This scraper member 31 is used for the second crank arm 3.
0B is provided with a groove for receiving the rib on the back side. The circulation trajectory is drawn in an elliptical shape as shown by a dashed line in FIG. 5, and the second crank arm 30B is in an almost upright posture (FIG. 5).
(See Figure 6), when it falls to the front and goes rearward (Figure 6,
7, the scrapers K1, K2, and K3 at this time are scraping the waste straw.) When the scraper member 31 approaches the base end of the second crank arm 30B, the scraper around the scraper is removed. It is configured to scrape out.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
