The other end of this ribbon conveyor 13 is fixed with a connecting tool 17 that connects the shaft 6 that protrudes into the aforementioned connecting cylinder and a pin 9 that is fixed in a cross shape to this shaft. For this reason, the connector 17 has a hole 18 into which the shaft 6 enters, a slit 19 that crosses the hole 18,
It has a push screw 20 for fixing the shaft 6 inserted into the hole 8 from the side, and the pin 9 is received in the slit 19. The connector 17 is fixed to the other end of the ribbon conveyor at the terminal 1 at the other end of the ribbon conveyor.
3' is made straight in the diametrical direction, and the connector is similarly provided with a slit 21 at the end opposite to the end with the slit 19, through which the straight end is passed and inserted into the female threaded hole in the center. The bolt 22 may be screwed in to deform the linear end 13'. Further, the flexible hose 12 is tightened and connected around the connecting tube 16 with a two-split tightening band 12'.

Then, the connecting tube 16 is fitted outside the connecting tube 8,
Both cylinders are provided with attachment/detachment devices 23 and 24 for releasably connecting the two cylinders in a state in which the leading ends of the connecting cylinders are in contact with the inner end surface 16' of the connecting cylinder.

In this embodiment, the attachment/detachment device 23 of the connecting tube 8 is a hook fixed on both sides. Further, the attachment/detachment device 24 of the connecting tube 16 hooks the hook 25 onto the hook,
This is a well-known tightening device or clamp that pulls the hook toward you by a toggle action when the lever 26 is rotated, and is also fixed on both sides of the connecting tube.
In FIG. 3, the upper clamp is inserted through the hook 25,
A state in which the hook 23 is tightened toward the front to perform the connection is shown, and when the lever 26 is rotated in the counterclockwise direction of the arrow in this state, the tightening is loosened as shown below, allowing the two cylinders to be separated.

Therefore, after putting paddy into the hopper in the field and bringing it to the dryer, open the inspection port 11,
Fit the connecting tube 16 to the outside of the connecting tube 8 while visually inserting the shaft 6 extending from the screw conveyor and the pin 9 fixed thereto into the hole 18 and slit 19 in the connector 17 on the flexible hose side. When the tip of the connecting tube 8 comes into contact with the inner end surface of the connecting tube, tighten the push screw 20, close the inspection port 11 with the lid 10, and attach each hook 25 of the attaching/detaching device 24 on the connecting tube side to each hook of the connecting tube.
