A drag chain conveyor is capable of being reversible so that material can be fed to the centre and conveyed in either direction of travel. The chain link (30) is in the general shape of a cross with one member (33) of the cross acting as the material pusher and the other member (32) being in the direction of travel of the chain (25) and serving as the chain link. The member (32) has a lug (35) at one end and a U-shaped enlargement (39) at the other end with the lug (35) of the link (30) pivotally connected to the enlargement (39) of an adjacent link (30) to form the chain (25). When the conveyor is driven in one direction, a drive sprocket engages one face e.g. 48 of the link (30), and when the conveyor is driven in the other direction, a drive sprocket at the other end of the conveyor engages the other face 49 of the link. <IMAGE> |
