Abstract
A conveyor flight for a chain comprising at least two spaced apart links, and two side plates that connect the links, with each side plate including two spaced apart extension pins extending from the side plate. The flight comprises a metal support, and the metal support includes two spaced apart cylindrical portions adapted to receive the two spaced apart extension pins. The flight also includes a flexible casing surrounding the metal support.
Claims20
A chain link assembly of a conveyor chain, the assembly comprising:
- a pair of parallel flight pins spaced apart by a distance, each pin having an outer surface, a first end, and a second end;
- a pair of spaced apart, parallel side plates mounted on the pins;
- a flight core secured to the first end of each flight pin and spaced apart from each side plate, the flight core defining a first side and a second side and further including an opening extending between the first side and the second side;
- and
- an encapsulation at least partially surrounding the flight core, the encapsulation filling the opening in the flight core.
A chain link assembly of a conveyor chain, the assembly comprising:
- a pair of parallel flight pins spaced apart by a distance, each pin having an outer surface, a first end, and a second end;
- a pair of spaced apart, parallel side plates mounted on the pins;
- a flight core having a first end and a second end opposite the first end, the first end including at least one surface secured to the first end of one of the flight pins, the flight core spaced apart from the side plates by a gap;
- and
- a sound dampening coating at least partially encapsulating the flight core.
A flight assembly for a link of a chain conveyor, the link including a pair of parallel side plates and a pair of parallel flight pins extending transversely through the side plates, the flight assembly comprising:
- a flight core configured to be secured to a first end of each flight pin, the flight core configured to be separated from each side plate by a space, the flight core including a first side, a second side opposite the first side, and an opening extending between the first side and the second side;
- and
- an encapsulation at least partially surrounding the flight core, the encapsulation filling the opening in the flight core.
