Abstract

A self-loading auger scraper has a sealed auger supporting bearing assembly that includes a fixed lower housing secured to the floor of the scraper bowl and an upper housing rotatably mounted in bearings in the lower housing. An auger drive means is supported on a cross beam at the top of the bowl; and the upper bearing housing and the drive means have generally coaxial opposed square stub shafts which are loosely but non-rotatably engaged by square sockets in the bottom and top of an auger shaft to provide slip connections. The length of the auger shaft is such as to permit the auger to float while maintaining the slip connections.
