PURPOSE:To release that portion of the loaded object which is affixed to bucket wheels, by equipping each bucket with a guide plate, which is to put a swing beam installed inside the wheel alongside the interior wall of the wheel, in such a position as on the wheel interior wall except over the chute, and thereby swinging the beam. CONSTITUTION:When a bucket 5 is going up, a roller 8 at the end of a swing beam 6 will take the bucket position under guidance of a guide plate 10. When the bucket rises further the roller 8 is put aside the guide plate 10 to make a swing round a pin 7 toward the chute side 11, and at the same time the object contained in the bucket 5 drops off into the chute 11 because there are no guide plates 9, 10 over the chute 11. When the rotation proceeds further, the swing beam 6 runs against the edge of the guide plate 9, and the impact induced thereby will drop off the portion of object affixed to the bucket 5 and/or wheel 4 into the chute 11. |
