Abstract
The feeder device located at the centre section of a front of a harvester. The feeder device comprises one or more flights configured for improving operation of the feeder device. The feeder device comprises a shaft including a plurality of flights. They extend substantially along the entire length of the shaft and are arranged in a spaced apart relationship with respect to each other. In this manner, a threaded-like formation defined by the spaced apart arrangement of flights extends substantially along the entire length of the shaft of the feeder device.
Claims21
A feeder device or drum for use in a harvester header for cutting and collecting crop material, the header including a rear opening arranged such that crop material cut by the header is transferred therethrough so as to be delivered to a feeder house of the harvester, the feeder device or drum comprising:
- a shaft which has a longitudinal axis and is mountable in the header so as to be rotatable about the longitudinal axis, the shaft having opposed end sections and a centre section located between the end sections, and being dimensioned such that when it is mounted the centre section is arranged in front of said opening;
- flighting on the end sections to direct crop material received into the header laterally inwardly towards a position below the centre section as the shaft rotates;
- and
- one or more paddles projecting from the centre section, the/each paddle extending diagonal to the longitudinal axis such that a surface thereof contacts cut crop material that is on a floor of the header so as to urge it towards said opening as the shaft rotates, thereby preventing build-up of crop material on the floor.
A feeder device or drum for a header to be attached to a harvester, the feeder device or drum comprising:
- a drum rotatable about a longitudinal axis thereof;
- and
- flights extending along the length of the rotatable drum, the flights comprising:
- outer flights adjacent ends of the rotatable drum to direct crop material received into the header laterally inwardly as the rotatable drum rotates;
- and
- one or more inner flights, located between said outer flights,
- wherein the/each inner flight comprises a paddle flight for engaging crop material that is on a floor of the header and moving it through said rear opening for delivery to the feeder house, thereby preventing build-up of crop material on the floor.
