Abstract

A cooling grate for bulk material, having a carrying plate for accommodating a layer of the material for cooling, and having conveying elements by means of which the material for cooling is conveyed in a conveying direction on the resting carrying plate and which comprise pushers, which are arranged in a movable manner on that side of the carrying plate which is subjected to the action of material for cooling, and a drive, which is arranged on the other side of the carrying plate and is intended for executing a lifting movement, each pusher being assigned an opening in the carrying plate and a transmission member, which is guided thereby and connects the pusher to the drive. The carrying plate is provided, at the openings, with in each case one collar, which at least at the front and rear, as seen in the conveying direction, has a seal acting between the transmission member and collar.
