A scraper-chain conveyor comprises a plurality of channel sections joined together end-to-end. Each channel section has a pair of side walls joined together by a floorplate. The floorplates separate upper and lower runs for a scraper-chain assembly which circulates within the conveyor. Each of the side walls has a generally sigma-shaped cross-section defined by a V-shaped recess in that side wall. Each floorplate is connected to the side walls of its channel section at the bases of their V-shaped recesses. Each side wall of each channel section is connected to the adjacent side wall of each adjacent channel section by respective connection means constituted by a pair of coupling elements and a coupling member. One coupling element of each pair is attached to one side wall of a given channel section, and the other coupling element of that pair is attached to the adjacent side wall of the adjacent channel section. The coupling elements project laterally beyond their respective side walls, and the coupling member connects the two coupling elements together. The two coupling elements are provided with recessed portions which receive the coupling member. The upper inclined portions of the side walls that define the V-shaped recesses are formed with apertures through which the coupling member can be inserted into the recessed portions from the upper run of the conveyor. |
