Abstract
A bottom unloader having a material conveyor for moving material from a hopper centrally located in a bin to a location outside of the bin. A drive apparatus mounted on the outer end of the conveyor operates the conveyor and adjusts the tension on the conveyor chain. The outer end of the conveyor has a door that is clamped to a closed position with eccentric clamping locks. An elongated auger collector is mounted on a rotatable turntable located in the central hopper. A cap having a side opening for the auger collector is mounted on the turntable. The auger collector is drivably connected with the conveyor so that, when the conveyor is operated, the auger collector is rotated. A separate drive operated with a hydraulic motor is used to move the auger collector in a circular path.
