I support the idea, and would like to hear more about it.
I have been around gravity silos used for aggregates for 50 years, and have a healthy respect for solids that flow rather freely.
It sure makes sense, and if cost effective, a wonderful idea.
That's why I was onto the gravity wagons, and even 2 or 3 of them. First, they would be easy to cover as they are rectangular, second they are after all....gravity operated, third, if they were installed as I stated......no.2 would feed no. 1(or 3 , 2, 1 whatever works best. Amount in bottom bin would depend on placement of bin no. 2,
Gravity feed wagons have the slope in the bottom, if no. 2 was cut into no. 1 just above the offsets, bin 1 could hold as little as 5 tons........I think you understand if you've done corn in gravity fed wagons.
Then we go to the door on the wagon. A typical door is roughly 18 inches square, and you slide it up or down to increase or decrease flow. But with an auger installed, you need a sliding door with a round hole on the inside panel. The door will be about 12x12, hole is say 7 inches for auger? Slide door down as auger is pulled(anyone who's done corn knows it's a 'beech' but can be done. Last fall I helped my BIL and only lost 5lbs of corn.
And even though gravity fed wagons are rated at 40lbs per square foot, a few extra pieces of angle welded to it can raise it to 60lbs fairly quickly.
