Underground roadway bunkerage comprises sequence of top cowl and bottom funnel bunker sections plugging together via seals with transport eyelets and swivel hooks all served by sectionalized screw conveyor.

摘要

The bunkerage housing (3) comprises funnel type bottom part and cowl top part joined releasably through a plug-in joint with integrated foam rubber seal, both housing parts to have flanged U-profile edges where they meet and both parts made from 8 mm gage iron sheeting. The housing as such is made up of a releasably interconnected sequence of lengthways bunkers (31-33) of similar size, the housing top fitted with swivel loading hooks and the bunker parts with transport eyelets (38). The housing stands on skids (41) through stabilizer tubes and bunkers are served by a screw conveyor (7) complete with slide ring seals and bunker part (31-33) sections (49,50,51) as releasably linked up by conical tube thread and keys. Rise pipe (10) has its own fluid container and mats (54,55) blown with vorticizing air through inlet (56). The first bunker part (31) filter (9) has plate fitted air inlets (59) with filter elements (57,58) which slide vertically in from the bunker part walls.
