I think I know what looks wrong, although I cannot be certain from your pictures of the conveyor belts - since they are outdoor ones, do they have a framework supporting them along the line of travel (as opposed to the struts you already have) - almost all outdoor heavy duty conveyor belts I've seen (images or in real life) have a significant amount of rollers, and so need a frame work (truss, usually) along each side to support those rollers - often the conveyor ends up semi-enclosed, with plates along the side frames, and a half-roof covering it (often half rounded, with struts from the framework supporting that).
If you have said frame work, then I stand corrected...
Hello Mike,
Right now as we speak....waiting for glue to dry, on a HO scale scratch built mobile crusher unit. Now what does this project have to do with yours, you ask ? The conveyor for removing the crushed rock is scratch built using and old copy machine drive belt. I'm still working on this project, but I'll take a picture for you ,top show you what I'm talking about.
Building conveyor's isn't that hard at all....yours looks pretty darn good.

Heres the almost done mobile crusher Mike. All I used for the conveyor was an old drive belt off of a cope machine.I think it was a cannon copier or something like that. It looks like a conveyor belt....must be a conveyor belt, besides from three feet away,only a rivet couter could tell.
Anyhow this project should be done and painted this weekend. Try the copy machine belt route....that is if you can find some.
Mike,
The sly, cunning trick is to enclose the belts in a long, slanted shed like the ones that come with Walthers New River Mining Co and Glacier Gravel. In many jurisdictions, the local codes require this to control noise, dust and falling materials.
The three-packs of conveyors Walthers sells are the kind used to move coal or gravel from a pile to a dump truck - 1940's era. Small, with wheels on one end, capacity probably measured in wheelbarrow loads per hour. Not the thing for unloading a hopper car, unless the hopper is loaded with coal to be sold retail for home heating. (As I said, 1940's era. Actually saw this in Port Washington, NY, in 1946 or so.)
The suggestion that more supports would be a good idea is also valid. Heavy duty conveyor belts are fairly hefty pieces of machinery, and the stuff they carry isn't exactly light weight either.
An operating conveyor can be an impressive model. Keeping it operating could get to be a royal PITA! Even a little bit of grit in the wrong place could cause havoc, and make you wonder if the whole idea was worth trying. If anyone has ever built a conveyor belt in ANY scale (including 1:1) that didn't end up with grit in inappropriate places, I've yet to hear of it.
