Abstract
The apparatus comprises a front-mounted collection means for a vacuum tank for the collection of liquid or semi-liquid materials. The collection means comprises a substantially V-shaped housing with a scraper at the bottom thereof, a height adjustable suction inlet at the apex thereof, and a pair of laterally adjustable pivoting wings for varying its width to correspond to that of an alley or gutter. A plurality of rotary feeders, each having a vertical axis of rotation, are mounted to the housing adjacent the scraper to prevent accumulation of the materials on the scraper. The feeders do not contact either the surface upon which the scraper is operated, nor the scraper itself, but serve to mix thick consistency materials with thinner consistency materials and also to dislodge any accumulation that does occur.
