Beach sand sifting machine

- Removes small gravel and debris from our beach sand. Just something I invented because I couldn't find anything on the market.
This uses a small DC motor with gear reduction, a small timing belt drive set up, with the belt connected to the motor and two PVC side rollers. The sifter cage just sits on the rollers. - Věda a technologie
What parenting should be like. Parenting done right. Wish I had a dad like this. Wish I had kids, I would do this all this all the time.
Brilliant and simple idea
Would you be willing to sell one or make a tutorial to make it?
Awesome!! That's something I'd wanna do all day every day :) so fun!!
I can't make a video tutorial on how to make one, but I can offer some insight to how I did it. I used a motor and drive belt to turn the small gray pipes, which then turn the screen barrel at the top from friction. The gray pipes are probably 2" gray electrical conduit, and I had some sealed bearings laying around that fit well into the end of the pipe and bolted to the wood. You can probably find something close on eBay for a few bucks each. If I did it again, I would space the gray tubes out another 1-2 inches further so they would have more pressure against the screen barrel. I had to add some wing-walk antiskid tape to make sure they would turn the screen consistently when wetter sand was in there. The screen barrel use a plain metal window screen (I wouldn't use the fiberglass kind -it won't last). The boards in the middle help stir up the contents, but don't make them wider than 2", and I think I added an angle so the sand would slide off faster (otherwise it lifts it like an elevator to the top one one side and stress out the system). The boards could be added to the outside if the end circles were larger (like another comment below - I really like that idea, it will require less force to turn the barrel, and more time contacting the screen for sifting). You still might need a scoop at the end to lift the rocks past the end cap if there is a lip/step remaining. Back to the drive system - if you use a rubber belt, you need a good tensioner spring and idler. I think this could be done easier with a bike chain and some sprockets from a farm store. I just used belts and motors I had laying around. When figuring how fast you need the motor to turn, you would use ratios of each diameter. For example, a 24 inch screen barrel could rotate at 10 rpm, then the 2" PVC pipes need to turn 24/2 or 12 times as fast, which is 120 RPM. You would do the same for any other drive components as well (say a 3" sprocket is fixed to the end of the PVC, and a 2" sprocket on the motor, the motor needs to turn 3/2 or 1.5 times as fast, which is 180 RPM to drive the sifting barrel at 10 RPM)
Good man, that Ethan...………..Darn good man.
Can you you add details or create another HOW-to video. How is the tumbler driven? What parts did you use? What kind of motor?
Awesome
Would you share motor hp capacity / brand and ..... How may I contact you? Thanks for the vid, Great idea!
Un consejo mi umilde opinión los refuerzos que corren a lo largo son mejor por fuera de la maya yo tengo uno más grande y el material se atora
Yes - I like that idea to run the supports for the barrel on the outside.
How do you make one?!
