I don't think it took much thinking to vibrate the hopper considering its been done for some time. Why do you think I mentioned it in my post 79. Dry Washers use a fan with a counter weight to vibrate the box. Hopper vibrators have been used for years in cement plants on the hoppers. Do a Google search of Hopper Vibrators or Bin Vibrators.
Yeah, that was GG in this thread:

In post #19 of that thread, I posted an offset weight vibration table video that shows what I was suggesting. No additional motors or wiring would be necessary running off the drum's motor.
The reason the pictures were invalid is because they come up as attachments, not a jpg so the Insert Image helper doesn't handle them

Simply wrap the url with without using the helper like this:
Aren't you kinda screwed at that point anyway? Now you're hoofing 6 or 8" rocks outta a hole and into the hopper? If I'm doing that, I can leave them in the hopper and let the hopper spray clean them off. But I'd rather have a low mortar tub wash station or something.

You didn't go all the way to Home Depot just to take that picture for me did you? Lol!
I agree! I didn't say I would, just trying to make a point. Any large rocks I will wash off in the hopper then throw out. I wouldn't use a wash tub. Just the hopper, less work the better.

Exactly Viper! I've been using vibrators for years. I ain't paying that extra money just to get my tires rotated! Lol!
You put a double pulley on your engine. One for the trommel and one for the hopper. The hopper pulley you put a counterweight on then hope that it doesn't vibrate apart.
I can think of an easier way to vibrate using the water pressure from a pump. Less hassles, cleaner design, etc. I am sorry you been using vibrator for years.... LOL...
Those tubs are great, have many uses, durable and cheap.
Help me list their uses.....
Pan into
use at end of sluice as a catch
great for recirculating tubs
can attach a rope and use like a sled to haul misc equip.
wash your mats in
float alongside your dredge to hold drinks, etc
Cover your motor during rain (motor cool and not running of course)
These are a few, please add to the list.
Go for the gold
GG~
Yes, I was considering them as a sled in one location. That same location is equipment free, but I figure I could get away with a classifier. So toss a shovelfull against a 2x4' classifier. Fines end up in a bucket and rocks/clods roll into the tub of water. A basket allows you to remove the large rocks after shaking them a bit in the water.Those tubs are great, have many uses, durable and cheap.

The local thriftstore has a broken treadmill I'm waiting for 1/2 off day to pick up...... and conveyer that will go up to the hopper on my trommel,
jog
True! I build it and screw something up its my fault. Even if I use somebody's idea and I screw it up or the idea didn't work its still my fault. No one else's.
Wait a minute Jog! Are you trying to clear yourself of any wrong doing when I start screwing up my trommel built from your design? Lol!
I do what I have to to get through the day. Lol!
Sorry I had to take a shot at what you said. Sometimes we humans say things then we say, "OH SH*T"... LOL
