The empty hopper 30 by the opening operation as described above is repeated after the lower opening and closing portion 50 is closed by the opening operation of the upper opening and closing portion 40, the operation of filling the inside of the hopper 30 is repeated. . In this case, the closing operation of the lower opening / closing part 50 may be performed by the reverse driving of the sub-motor 56, but may be naturally closed by the weight of the front opening and closing plate 51 and the rear opening and closing plate 52.

On the other hand, the potato that is simultaneously discharged from the plurality of selected hopper 30 is dropped by the guide pivot plate 70 is dropped to the discharge conveyor 60 of the selected one of the two discharge conveyors (60, 60 '). After that, the transfer is made for packaging through the discharge conveyor (60), and the discharge opening and closing door (61) is opened at the end of the discharge conveyor (60) by driving the hydraulic jack (63).

Therefore, the worker only needs to open the packaging bag on the discharge side, the packaging of the quantity of potatoes quantitatively measured.

In particular, since the fall of the potato from the hopper 30 is made continuously, the guide pivoting plate 70 as shown in Figure 7a, b around the hinge pin 71 by the reciprocating operation of the cylinder (72). The rotation is made, and thus the potatoes can be alternately guided to the discharge conveyors 60 and 60 'on both sides.

Accordingly, it can be seen that the discharge speed and the packaging work are simultaneously performed through the respective discharge conveyors 60 and 60 'on both sides of the apparatus, thereby increasing the working speed.
