Feeding stand for pig sty - has pivoted barrier pivoted from vertical rest position to allow access to trough

摘要

The feeding stand has a feeding trough (10) which is enclosed on all sides by a blocking grid (11) at least one long side of which is provided by a pivoted barrier (27, 28) which is rotated about a horizontal, longitudinal axis (29, 31) to allow access to the feeding trough (10). The barrier (27, 28) hangs vertically in the rest position and is displaced via an operating drive (44) and intermediate coupling rods (47, 48, 51, 52, 56, 57). Pref. the operating drive (44) uses a hydraulic or pneumatic cylinder with its piston rod displaced axially to raise the barrier (27, 28) and released to allow the barrier (27, 28) to drop back into the blocking position. ADVANTAGE - Allows automatic feeding control.
