Abstract

PURPOSE:To facilitate posture control of onions on a conveyor and enable orderly conveying treatment by raising and lowering nipping lugs with a cam and engaging tools, nipping and opening bulbous parts of the onions. CONSTITUTION:Onions dug up by a digger with revolution of a conveyor 5 are received by buckets 3 and conveyed to the upper side in the back. In a stroke for receiving the onions fed from the digger, nipping lugs 7 are in an opened posture (b) tilted to the front side to facilitate receiving of the onions. When the buckets 3 receiving the feed of the onions are conveyed upward on the back side, the nipping lugs 7 are raised to a nipping posture (a) by a cam 8 provided in the course thereof, engaged and kept by engaging tools 10. When the onions are conveyed in this state, engagement of the engaging tools 10 are released by a cam 9 to change the nipping lugs 7 from the nipping posture (a) to an opened posture (b). Thereby, nipping of the bulbous parts 6 of the onions is released to drop the onions.
