Rotate and close to the inside of the left fuselage.

When the cross-direction operating lever 27 is operated, unless the movable conveyer 21b is at the highest position, even if the cross-direction operating lever 27 is operated to the rear of the machine body, the rotating electric cylinder 24c will not operate and the rotating arm 24b will be pivotally supported. It does not rotate around the axis and open outward to the right. That is, only when the movable transfer conveyor 21b is at the highest position, the cross-direction operation lever 27 is operated rearward of the machine body to operate the rotating electric cylinder 24c to rotate the rotating arm 24b around the pivot shaft. It can be opened outward to the right.

In addition, a load sensor 28 is provided on the mounting table 26, and only when the flexible container bag 22 suspended on the hanging hanger 25 is lifted and the bottom of the flexible container bag 22 is separated from the mounting table 26 (the load sensor 28 Only when the flexible container bag 22 is no longer detected), the cross direction operation lever 27 is operated to the rear of the machine body to operate the rotating electric cylinder 24c to rotate the rotating arm 24b around the pivot shaft and move to the right outer side. can be opened to

In addition, a photo sensor 29 is provided at the right outer end of the mounting table 26 to detect that there is an object above. , the flexible container bag 22 is not above the right outer end of the mounting table 26 (the flexible container bag 22 is placed If it is not detected that the pedestal 26 has moved to the right outer side of the right outer end, even if the cross-direction operation lever 27 is operated to the left to rotate the movable conveyer 21b around the pivot shaft to lower it. , the vertical movement electric cylinder 21c does not operate, and the movable conveyer 21b does not move downward. Therefore, when unloading the flexible container bag 22 hung on the hanging hanger 25 to the field, it is possible to avoid the flexible container bag 22 from accidentally contacting the right outer end of the mounting table 26.

A hook open/close switch 30 for opening and closing the four hooks 25 a of the hanging hanger 25 is provided at the upper end of the cross-direction operation lever 27 .
