I thought it was sucked up by vacuum, but no, there's actually an screw shaped augur inside the arm which works as an elevator for the grainpic.twitter.com/SfxGm7XYVx

Saw this image of grain being unloaded by two mechanical arms at a port in China (from wsj). I wondered how they did that and it turns out it's super interesting.pic.twitter.com/2rAP1HIuBM

This youtube video shows it in action. It's very cool. At first I thought there's no way this is an augur because then you'd miss a lot of the grain towards the end but they have a solution for that! Drop a bulldozer in the cargo bay! https://www.youtube.com/watch?v=BFKyIbXgIuY …pic.twitter.com/V4BeJuPT2m

Farming 101. Happening inside all grain bins in north America today and for decades (slightly diff equipment and config than ships). For the record there are ‘GrainVacs’ by Brandt and others.https://images.app.goo.gl/xkTHkB13FRWK6YQCA …

Cool but this is a vacuum right? Or does it also have a screw in the tube?
