The shaft ends of the gate valves 2 and 13 are supported by the support plate 11, and the shaft end of the gate valve 14 whose tilt position can be changed is also supported by the support plate 11.

A large outlet 16 through which the sorting barrel 8 can be pulled out of the machine is opened in the rear machine wall 15 forming the machine body, and is configured to be openable and closable by an opening/closing plate 17. This opening/closing plate 17 is formed into a slightly larger circular shape than the outlet 16,
Legs 18, 18 extending from both sides of the lower part are fitted onto a support shaft 20 inserted through horizontal tubes 19, 19 welded to the machine wall 15, and rotated about this support shaft 20, thereby The outlet 16 can be opened and closed as shown in FIG.

Furthermore, flanges 21 and 22 are formed on the front and rear sides of the outer peripheral surface of the sorting barrel 8,
The drive wheel 5 is attached to each outer surface of the flanges 21 and 22.
The inner surfaces of the sorting cylinders 5, 6, and 6 are in contact with each other, and the movement of the sorting cylinder 8 in the rotational axis direction is restricted, so that the sorting cylinder 8 rotates at a fixed position. Below the sorting cylinder 8, a set of guide rails 23, 23 are horizontally suspended along the sorting cylinder 8 in parallel in the front and back direction.

That is, the rear end portions of the guide rails 23, 23 are pivotally supported by the tips of arm portions 24, 24 protruding from the support shaft 20, and diagonal grooves 25, 25 are provided at the front end portions of the guide rails 23, 23, respectively. Horizontal shafts 26, 26, which are erected so that the machine body is visible, are inserted into the oblique grooves 25, 25 and supported, and the upper surfaces of the guide rails 23, 23 and the outer peripheral edges of the flanges 21 and 22 are spaced apart from each other by a gap M. There is.

The rear side of the sorting barrel 8 is bent inward to form an annular grain spill prevention wall 27 , and an elastic annular body 28 made of rubber is fitted into this grain spill prevention wall 27 . A cylindrical flange 29 is removably engaged with the flange 29 .
