Note that the slide valve is needed to connect the unloader to the collar. The collar attaches to the bottom of the bin and is available in different cuts to create the desired auger angle. They are available in horizontal, 30-degree, and 45-degree angles.
Here is an example of an assembled auger for discharge. The top collar is horizontal and attaches to the bottom of the bin. The slide valve is then attached to the collar and controls the flow of grain to the box. The auger box is connected to the slide valve and collects the grain for the auger to grab and move to the discharge end of the tube.
The un-loader box has a nylon bushing (in blue, labeled 'A' below) or bearing stub for the auger to rest on.
