Okay, If I get you, you are on a surface that is level or slightly above where the Raptor sits. When you say "pushing" are you referring to feeding via mechanized means? Is the material that you want to convey wet? Ever? How far away will the inlet be from the discharge? 5'? 25'? Easily moveable... by 6 guys carrying it? Towing it? I don't mean to sound smart alecky, but I've spent years designing and deploying material handling equipment, though not in the mining industry and I may have some suggestions that will save you a lot of money and/or trouble depending upon the circumstances, but I need details of exactly what you are trying to do and if possible, the budget that you have for the conveyor project. Even if I am unable to help, I bet that with some details, there is help to be had on the forum.
May not be much help but here are a couple of ideas & a link.
1) If the material that you are moving is above the highbanker, why not use just a trough and let you pump wash the dirt to the inlet hopper.
2) Look at fertilizer conveyors online for ideas and adapt from there.
3) Check out the C-Series Incline conveyor from Redline systems Inc. I would put in the hyperlink, but I don't know if it is allowed.
This conveyor could be built in stages and kept "relatively light" Using 3" x 2" Angle Iron sides, Ladder-Frame the bottom and cover the ladder frame with UHMW or expanded metal leaving a gap of maybe 1 " on each side. Build the Head and Tail sections to bolt on so that length could be added as necessary though you would need to splice or replace the belt. Make sure to use caged or winged pulleys for the head & tail. For handling purposes I'd be inclined to tail drive the the conveyor unless the motor and drive would interfere with operations. I'd also use a smooth-top belt instead of roughtop. If you have to start inclining the belt, you could make the U-brackets for the flights out of 2" sections of 8" channel, use SS Fanged-Norway-Head Bolts to attach the flight brackets to the belt. Use 2" wide strips of PVC (probably PVC 350) belting laying sideways as Flights though I'd add a small section of angle-iron to secure the center of the flight to the belt. I'd also recommend skirting with some light belting held on by strap bolted to the side frame. Make sure to slot the skirt for adjustability. Note that the length of the conveyor will make a ton of difference in the structural requirements and weight. For a design like I described, I wouldn't exceed 10-12 feet without beefing up the support by using Channel or tubing for the sides. Also, additional length will require some attention to support structure to prevent sagging and twisting. Just some ideas and I'm sure that there are better ideas to be had. Good Luck.
I like ats idea about a series of troughs or metal channels like sluice sections that AT sugested even ran flat with a smooth bottom most of the material will wash along and also it pre desolves the material before it gets to the high banker. and anthing left behind might be nuggets and pickers. you have a great sitiuation if your sopurse of pay aluvium is higher than the highbanker. I have dreamed for years pf conveyer feet even if only from ground level to hip high because that seems the hardest word compaired to raking or hoeing the material closer. the greatest advantage of conveyor feet is you can steady the rate of feed so flow in the high banker does not surge. this way you can buckit the pay material to the feed hopper of the conveyer then go off and do other stuff while it feeds steady
