Claims
- 1. In a loader for liquid manure products:
- a housing having an intake opening, a discharge opening, and an arcuate flow passage for said products communicating said openings with one another for product flow through the housing along an arcuate path of travel;
- an arcuate perforated member across said intake opening and spaced inwardly from the latter within said passage,
- said discharge opening being spaced from said intake opening downstream from said member flow; and
- a rotary sucking impeller mounted within said space in substantially concentric relationship with the member for drawing products into the passage on one side of the impeller, screening foreign objects from the products along the member, and propelling such foreign objects back out the intake opening on the opposite side of the impeller,
- said housing having a passage-defining wall,
- said member merging with said wall on said one side of the impeller and terminating in a free end spaced from said wall on said opposite side of the impeller.
- 2. In a loader for liquid manure products as claimed in claim 1, wherein said member includes a grid having a series of laterally spaced apart rods disposed substantially concentrically with the impeller, each rod extending in the direction of impeller rotation.
- 3. In a loader for liquid manure products as claimed in claim 2, wherein said grid is closely spaced from the periphery of the impeller generally above the latter.
- 4. In a loader for liquid manure products as claimed in claim 1, wherein said passage extends in a generally converging spiral from said intake opening to said discharge opening, said member being disposed across the passage between and in spaced relationship to said openings at opposite ends of the spiral.
