The front ejection nozzle 107 and the rear ejection nozzle 108 of the rear pot pipe 91 reciprocate in the left-right direction intersecting the transfer direction of the plug-pot seedling pot sheet 1. Cleaning is performed by violently obliquely colliding with the left and right sides in the transfer direction in 2. Further, the cam bodies 102 and 103 alternately push the front operation arm 95 and the rear operation arm 100 to rotate about the shaft 98, and move the front pot pipe 90 and the rear pot pipe 91 in opposite directions. This prevents the entire apparatus from vibrating.

The pot sheet 1 cleaned by the pot sheet cleaning device 7 is placed on the mounting plate 27 and discharged from the discharge port 76 of the pot sheet cleaning device 7 to the transfer table 120 of the drying device 9. After being transferred, it is dried by the blast blown out from the outlet 124 of the blower blower 121 and is transferred to the transfer table 125 of the pot sheet stacking device 11. When the motor 128 drives the transfer table 125 to feed the pot sheet 1, the mounting plate 27 on which the pot sheet 1 is mounted is transferred to the support and transfer roller 39 of the ascending / extracting mechanism Y to turn on the presence / absence detection switch 61. The up / down motor 53 is rotated to move up, and the pull-in switch 58 rides on the holding hill portion 59 to further rise between the supporting claws 28 that are being pulled in.
