As shown in FIGS. 6 to 8, the coupling member (33) includes a substantially oval driven rotary body (43) fixed to the front end of the auger shaft (22a) of the transverse feeding auger (22). A substantially diamond-shaped main rotating body (44) fixed to the end of the drive shaft (34) projecting to the outside of the rear portion of the gear box (36), the auger shaft (22a) and the drive shaft (34) Are located on the same axis, and the front and rear surfaces (43a) and (44a) of the slave and main rotating bodies (43) and (44) are opposed to each other, and the auger shaft of the front surface (43a) of the slave rotating body (43) is opposed. Two substantially trapezoidal engaging protrusions (45) are provided at a constant radius (r) position at intervals of 180 degrees around (22a), and the drive shaft of the rear surface (44a) of the main rotating body (44). Roller shaft is placed at a constant radius (r) at 180 degree intervals around (34) Two engaging rollers (47) are rotatably supported via (46), and when the drive shaft (34) is rotationally driven, the rollers (47) are attached to the trapezoidal bottom side (45a) of the engaging protrusion (45). ) Are brought into contact with each other to integrally drive the auger shaft (22a).

In addition, a guide member that is a guide member on the base plate (3a) of the machine base (3) on the right outside of the rotation locus of the engagement protrusion (45) via the support column (48) and the pivot shaft (49). A bearing (50) is provided to guide the bearing (50) to the substantially oval flat portion (43b) on the outer periphery of the sub-rotor (43) when the grain tank (15) is opened outside the machine or stored inside the machine. It is configured such that the tank (15) is opened or stored while the flat portion (43b) is kept substantially horizontal. In other words, the two opposing flat portions (43b) (43b) of the sub-rotor (43) are parallel to each other and wide between the flat portions (43b) (43b) are formed. Immediately after the sub-rotating body (43) is in the horizontal horizontal position, the bearing ring (50) is provided at a position where the engaging protrusion (45) is engaged with the engaging roller (47) of the main rotating body (44). The sub-rotating body (43) is integrally engaged with the main rotating body (44).

Further, the two engagement protrusions (45) (45) are arranged such that the trapezoidal bases (45a) (45a) are arranged on a substantially straight line (L) about the auger axis (22a). Then, when the roller (47) on the main rotating body (44) side is aligned with this straight line (L) when the tank (15) is stored, the trapezoidal oblique side portion (45b) of the protrusion (45) contacts the roller (47). The roller (47) is rotated around the drive shaft (34) in contact with each other, and the horizontal step gap (A) between the two rollers (47) is divided into two protrusions ( When the width is larger than the upper and lower maximum outer width (B) of (45) (A> B), the engagement is made possible.

The present embodiment is configured as described above, and the outer peripheral side portion of the driven rotary body (43) comes into contact with the guide bearing (50) during the storage operation of the tank (15) and the flat surface portion ( When 43b) is guided along the bearing (50), as shown in FIG. 7, the driven rotor (43) keeps a horizontal horizontal position and approaches the main rotor (44) side. When the horizontal step gap (A) between (47) is larger than the maximum outer width (B) of the projection (45) (A> B), the roller (47) does not come into contact with the drive shaft (34). The sub-rotating body (43) moves to a predetermined position where the axis of the auger shaft (22a) coincides with the main rotating body (44). On the other hand, when the horizontal step gap (A) between the rollers (47) is smaller (A ≦ B) than the maximum outer width (B) of the protrusions (45), the roller (47) has a moving side hypotenuse of the protrusions (45). When the part (45b) is in contact, the roller (47) is rotated about the drive shaft (34) along the hypotenuse part (45b) so that the sub-rotating body (43) becomes the main rotating body (43). 44).

As described above, when the grain tank (15) is stored inside the machine, the engagement with the sub-rotation body (43) is irrespective of the directionality of the position of the roller (47) in the main rotation body (44). It can be done accurately, and it not only saves the labor of adjusting the position of the rollers (47) and the protrusions (45) as in the past, but also prevents damage to the drive system due to erroneous storage. Maintenance of (14a) and the drive system can be improved.
