Embodiment Construction

[0036] The disclosed embodiments are improvements on the above-described subject matter of the '932 patent, a description of which can be found in the "Summary of the Invention." More specifically, as Figure 5 As shown, the modifications relate to the structure of the first linkage assembly 26 and the second linkage assembly 30 . Still more specifically, as Figure 5 As shown, the improvements relate to the chain and flight assembly 118 and its use on a conveyor, the assembly including a first linkage assembly 126 and a second linkage assembly 130 . As mentioned earlier, as Figures 6 to 13 As shown with respect to the first linkage assembly 126, each linkage assembly also includes two spaced apart side plates 146, each side plate 146 having two spaced apart openings 150, each opening 150 receiving a different one of the transmission pin 134. The conveyor chain and flight assembly 18 also includes a swivel assembly 62 that connects the two link assemblies 26 and 30 , the ...

Abstract

The invention relates to chain and flight conveyor assembly. The invention discloses 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.

Description

technical field [0001] This application relates to a chain and scraper conveyor for conveying material in the mining industry, and more particularly to an improved design of a chain and scraper conveyor with an improved drive sprocket assembly. More specifically, the present application relates to conveyor chains for continuous mining machines and chain hauling units. Background technique [0002] Conveyor chains for use on continuous mining machines and chain hauling units must have the ability to bend sideways to allow them to turn. For this, they include rotating linkages. Unlike links from standard roller chains or stud-bushed chains, rotary links cannot be driven internally by sprockets because the space inside is mostly filled with rotating The pin and the lugs (lugs) that surround the swivel pin. The rotary link can only be driven by a sprocket on its outer end. [0003] US Patent 6,662,932 to O'Neill (the '932 patent) describes an improved chain and scraper conve...
