Abstract

A sliding cover (5) for a silo discharge outlet comprises a frame (17, 19) with flat top and bottom surfaces. In its thickness is a closed bore (13), forming a cylinder for an actuator piston (23) which slides in the bore, its rod (14) being attached to a bracket (15) on the silo body (2). The cover slides over the flat surface (24) of the filler opeining, being operated by the power cylinder and controlled by guideways each side. On the underside of the cover is an inset gasket (11), deflated when the cover is open, or in motion. When closed, this gasket inflates and the cover rises to lock against flanges on the guides.
