摘要

A dung removal conveyor (18, 20) for multi-deck poultry battery-nest installations with dropping plates arranged under the roost grates, including a single chain (12) centrally connected to scraper crosspieces (14) so as to allow limited movement therebetween, an oil pan (22), and oscillating plunger apparatus (27) for dipping into the oil pan and then extending to a position where oil carried thereby falls to lubricate the conveyor.
