Chips drop in from the top.
The cross pipe has a 4 vaned rotor driven by a gear reduction unit. The rotor has rubber tips that seal against the end plates and the horizontal pipe. As the rotor turns, chips drop between the vanes and are carried around to the bottom where they fall into the trailer. The vanes allow only a small amount of air to be drawn up into the cyclone each revolution. I suspect that such a unit is not worth it for home use on a 5 hp fan.
