ABSTRACT:
A trough has side walls tiltable around a shaft, which is horizontal and disposed radially relative to a rotational axis for a plurality of troughs arranged in a circle. The shaft is supported as a cantilever. Linkage mechanisms connect the tiltable side walls to a vertically displaceable member. When the displaceable member moves upwardly, the side walls swing outwardly to discharge the contents of the trough. When the displaceable member moves to its lower position, the side walls come together to close off the bottom of the trough. When the trough is closed, the linkage mechanism is in an overcenter locked condition, whereby the weight of produce in the trough resting on the side walls cannot displace the side walls to the open position.
