It is attached by.

  The stock source side of the left two rows of harvested cereals is sandwiched between the left root source transfer chain 17a of the left root source transfer device 17 and the left stock source guide guide 31a, and transferred to the junction (I). In addition, the stock side of the right two rows of harvested cereals is provided at the right bottom base transport chain 18d of the right bottom base transport device 18b, the right stock base guide 31b, and the tip of the right stock base guide 31b. It is sandwiched between the auxiliary right stock former guide 31d attached to the mounting plate 31e and transferred to the junction (A).

  As a result, only one front mounting plate 30c for mounting the left / right stock former guides 31a, 31b is required, which reduces costs. Moreover, it is easy to install. Furthermore, since two reaction forces can be used, the wire diameter can be reduced.

  The right stocker guide 31b and the auxiliary right stocker guide 31d are operated by pressing the stocker side and guiding the right stocker guide 31b. The working length (L2) of the culm sandwiching and transporting of the stock guide 31d is a configuration formed to have substantially the same length as shown in FIG.

  As a result, the right lower root transfer chain 18d is the slack side on the side where the cereals are scraped, and can be caught lightly. The rigid right stock former guide 31b can sufficiently perform the function. Further, the rear of the lower right root transfer chain 18d can securely hold the stock by the loosening of the chain 18d and the escape of the elastic material of the auxiliary right stock guide 31d.
