Since the base end 20a of the float sensor 20 for detecting the thickness of the paddy layer on the swing sorting body 7 is provided directly below the intake surface 18, the limited space in the handling room 1 is effectively used. In addition, adverse effects such as intrusion of dust or collision of foreign substances which hinder the operation of detecting the layer thickness of the float sensor 20 may be caused in the base end 2.
0a, the dustproofness and durability of the float sensor 20 can be improved, and high accuracy can be maintained for a long time. Float sensor 20
Is located at the rear of the fuselage from the second return port 17, so that the paddy threshed by the first handling cylinder 3 passes through the second return cylinder onto the swing sorting body 7 from the second return port 17. The detection of the paddy layer thickness including both returned second products is performed, and the accuracy of the automatic sorting control linked to the detection of the paddy layer thickness can be improved.
