Binding machine 6
Is provided.

On a guide rail 8 erected between the left and right frames 7, 7 of the straw bundling machine 6, a stock arranging device 4 and a tying device 5 are slidably installed.

Reference numeral 9 denotes a transmission shaft formed in a hexagonal shape. The transmission shaft 9 is mounted on the transmission shaft 9 so as to rotationally drive the scraping devices 10, 11, and 12, and for reciprocatingly swinging the stock end alignment plate 3. The drive eccentric wheel 13 is slidably mounted on a shaft.

The scraping device 10 that scrapes the stock side of the straw is a stocking device 4
