Abstract
A system and method for operating a manure conveyor device. The method includes driving a first return roller about which a manure conveyor belt circulates at a first rotational speed, and driving a second return roller about which the manure conveyor belt circulates at a second rotational speed. During a first interval the first rotational speed exceeds the second rotational speed, and during a second interval the second rotational speed exceeds the first rotational speed.
Claims16
A manure conveyor device, comprising:
- a liquid-permeable conveyor belt drivable around first and second return rollers;
- a manure collection channel associated with a discharge end of an upper half of the conveyor belt;
- a urine collection channel associated with a discharge end of a lower half of the conveyor belt;
- and
- a liquid-tight trough through which the lower half of the conveyor belt travels,
- wherein the conveyor belt comprises a perforated plastic circulating manure conveyor belt arranged underneath a manure permeable floor associated with livestock operations, and
- a ground side of the trough is formed by a plastic sheet;
- wherein the first return roller is driven faster than the second return roller during a first interval,
- the second return roller is driven faster than the first return roller during a second interval,
- the first return roller and the second return roller are not driven during a time period between a first interval and a second interval.
