Anyone have any experience making a rig like this, or have an idea how to
arrange the plumbing parts to do this?

Stuff like this, the container/store is under vacuum too so the nuts
don't go through the fan.
When it is full the motor is shut down and the (nuts in your case)
fall out of a trap on the bottom.

One some things, the trap opens outward and is held shut by the
vacuum. When the vacuum is cut, it opens automatically and the stuff
falls out.
Depends on how dense pecan nuts are as to whether this is possible
without a latch..
