  Specifically, the handling cylinder 600 ′ according to the present embodiment has a front plate (not shown) instead of the front plate 620 and the rear plate 630 as compared with the handling cylinder 600 according to the first embodiment. And a rear plate 630 ′ (see FIG. 19), and a plurality of tooth handling frames 700 ′ (see FIG. 19) instead of the plurality of tooth handling frames 700.

Also in the present embodiment, the front plate and the rear plate 630 ′ have substantially the same configuration with respect to the shape of the support surface.
Accordingly, the following description regarding the support surface of the rear plate 630 ′ may be applied to the front plate.

Also in the present embodiment, one or a plurality of the handling cylinder 600 ′ corresponding to the first and second intermediate plates 640 (1) and 640 (2) in the handling cylinder 600 according to the first embodiment is used. Intermediate plates (not shown).
When the intermediate plate is provided, the intermediate plate is provided with a support surface having substantially the same shape as the support surface of the rear plate 640 ′.

  As shown in FIG. 19, the rear plate 630 ′ includes the plate body 631 and a flange 635 ′ extending from the plate body 631 in the axial direction of the handling cylinder shaft 210.

  The flange 635 'has a plurality of flat surfaces 636' that are spaced around the barrel shaft 210 and act as the plurality of support surfaces.

The handling cylinder 600 ′ according to the present embodiment is also provided with six tooth handling frames 700 ′, similarly to the handling cylinder 600 according to the first embodiment.
Accordingly, the flange 635 ′ is formed to have six flat surfaces 636 ′.

FIG. 20 is an enlarged view of a part XX in FIG.
As shown in FIG. 20, the tooth handling frame 700 ′ includes the support bar 710, the plurality of tooth handling 730, and a mounting bracket 715 ′.

  The mounting bracket 715 ′ includes a front mounting bracket (not shown) connected to the front plate and a rear bracket 715R ′ (see FIGS. 19 and 20) connected to the rear plate. First and second intermediate mounting brackets (not shown) connected to the first and second intermediate plates, respectively.

The front mounting bracket, the first intermediate mounting bracket, and the second intermediate mounting bracket have substantially the same configuration as the rear mounting bracket.
Therefore, the following description regarding the rear mounting bracket 715R ′ is also applied to the front mounting bracket, the first intermediate mounting bracket, and the second intermediate mounting bracket.

  As shown in FIG. 20, the rear mounting bracket 715 </ b> R ′ has a pair of mounting pieces 716 ′ connected to the support bar 710 so as to extend to both sides in the width direction of the support bar 710.

  The pair of mounting pieces 716 ′ are directly or indirectly on the flat surface 636 ′ in a state where the support bar 710 is positioned along the axis of the barrel shaft 210 on the outer side in the radial direction of the flat surface 636 ′. Further, a through hole 717 in which the longitudinal direction is a long hole along the circumferential direction of the handle cylinder shaft 210 and the fastening member 720 is inserted is formed.

  21 and FIG. 22, from the state where the tooth handling frame 700 ′ shown in FIG. 20 is attached at the reference attachment position, the tooth handling frame 700 ′ is rotated on the upstream side in the rotational direction of the handling barrel shaft 210 and rotated. The state attached in the position moved most to the direction downstream side is shown.

  As shown in FIG. 20 to FIG. 22, also in the handling cylinder according to the present embodiment having such a configuration, the mounting position of the tooth handling frame 710 ′ is the radial direction based on the axis of the handling cylinder shaft 210. In the threshing operation, the relative position between the tooth handling 730 and the dust feed valve 203 and / or the optimum relative position between the tooth handling 730 and the receiving net 230 can be easily changed. Can be optimally set according to the amount and state of the harvested cereal.

  In each of the embodiments, the through-hole 717 formed in the mounting racket 715 (715 ′) is a long hole along the circumferential direction of the barrel shaft 210, and the fastening member 720 is the through-hole. Although the attachment position of the tooth handling frame 700 (700 ′) can be adjusted within a range in which it can move relatively within 717, the present invention is not limited to such a form.

  For example, the mounting bracket 715 (715 ′) is formed with a plurality of through holes arranged along the circumferential direction of the handling cylinder shaft 210, and the handling hole is changed by changing the through hole through which the fastening member 720 is inserted. It is also possible to adjust the attachment position of the tooth frame 700 (700 ′).
