The sorting unit 12 includes a rectangular plate-shaped base material 20 attached to the conveyor 10, and a bowl-shaped agricultural product holder 2 disposed on the base material 20.
1 and a donut plate-shaped rotating body 22. There are a plurality of holding bodies 21 (six in this example).
It consists of an expanding/contracting piece 21a, the center of which is a sorting hole 19. The expansion/contraction piece 21a has an extending portion 21b extending horizontally outward from the lower end thereof. The extending portion 21b is slidably attached to a guide member 23 provided radially on the base material 20 (see FIG. 5), and as will be described in detail later, the extending portion 21b is attached to the guide member 23 radially on the base material 20. By sliding in the radial direction guided by 23, the expansion/contraction piece 2
1a expands and contracts.

The rotating body 22 has a guide portion 2 consisting of an arc-shaped long hole.
Six guide members 4 are formed at regular intervals, and a guided member 25, which is provided in a rib shape and projects from the extending portion 21b, is fitted into the guide portion 24. 26 are rollers provided at the four corners of the base material 20,
The outer peripheral edge of the rotating body 22 contacts these rollers 26 and rotates horizontally. In FIG. 4, 30 is a protrusion extending from the rotating body 22, and a guided portion 31 made of a roller is provided at the tip thereof. 35 is a spring material for supporting the rotating body 22; Along the conveyor 10, the guide portions 34, 34
