Chain and flight conveyor

摘要

A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.

主权项

1. A chain link assembly for a chain conveyor, the assembly comprising:
a pair of pins arranged in parallel and spaced apart from one another, each pin having a first end and a second end extending along an axis; a pair of side plates on the pins, the side plates being arranged in parallel and spaced apart from one another, the pins being connected to and extending between the side plates; and structure connected to and extending between the side plates, the structure preventing at least one of movement of the side plates toward one another and movement of the side plates away from one another, the structure being positioned solely on one side of the axis of a first of the pair of pins and solely on one side of the axis of a second of the pair of pins.
