I want to rig up a vacuum to pick up hard objects, like pecans. They
obviously cannot pass through the vanes of the motor. I want them to
dump into a hopper after going past a screener to remove husks,
rocks, dirt, and leaves. I want only the nuts to come out.

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


Have you considered rigging a large net/tarp under the tree that funnels the
nuts into a container as the fall. Or even a heavy tarp on the ground you can
just sweep them off of with a push broom.
