Default Top Soil Screener

Needed to sift some stones out of a huge pile of top soil I have. I'm going to be building a vibrating screener over the winter, but had to get some fill. I had an old bucket for my Case 1835C Skid Loader with the bottom shot. Cut the bottom out, rounded up a bunch of scrap rebar, and made this gizzmo. Works great. Shakes the crap out of me though. Last pic is of some screened fill.

Looks good. Now with that tool why do you want to build a screen plant ?

Because using this is hard on the loader. Requires rapid movement of the hydraulic controls, bucket tip forward, bucket tip back. Sort of a shaking think set up. Not to mention, it's like riding a bucking bull in the drivers seat.

Besides, I've got lots of steel, and a vibrating compactor I bought from Government Liquidation auction site. If I build it right, might be able to rent it out.

How about this one ?

I would divide the screener into 2 sizes, divide the belt as well,
and put a diverter (left and right) as the stuff went over the top roller.

I like that little one! Any more pics/info? I've been looking for a smal screen that would work with a small/mini excavator, almost all are designed for a skid steer/loader, and really don't work for an excavator. That would work really well though! It would be small enough that it could even be taken to small job sites to screen on site. I'd have to think that is a commercial unit, either that or a really well made home built.

Grey,
I snapped those photo's when I stopped at the LWS
next door (this was on a sewer job).

It was originally a commercially produced unit, but had been re-powered.

The vibration unit looks just like the little unit on a harbor freight
plate compactor....(hint, hint)

I don't know why this unit drives the conveyor from the bottom roller,
I would think that the conveyor should be driven on the top roll.

This is the rest of what I've got.

We have a major manufacturer of screening plants and stackers(conveyors) near us, in fact I did some excavating there earlier this year. We got to talking about the drive systems on the conveyors, a bottom drive is common on short units like this where belt stretch and load aren't huge. Top drive is better, since you are pulling the load up, but it's not the end of the world. I see that Honda has a gear reduction built in, with a large drive pulley then driving the shaker, and roller chain driving the conveyor. Getting those speeeds right would be crucial, but the use of a jack shaft or two would give more flexibility for the home engineer.

As to a shaker such as those, another easy to do option is an eccentric shaft, easily made on a lathe with a 4 jaw chuck. Now you've got me really thinking....and oh how I wish I had a shop to imagineer in this winter!!

Nice build, PA! How about adding a shaker to what you've already got?
A hydraulic or 12V electric motor could drive a wheel with a rod pinned near the rim with the other end connected to the bucket. (like a steam locomotive drive wheel). With the flick of a switch or the push of a valve your bucket could shake without you loosing any back teeth.

Nice job “PA” A bucket like that is very nice in certain applications, but it’s hard to beat a screening plant if you have very much to do.

Do you have a plan in mind for your screen? Here is one I built, maybe it will give you some ideas.

Nice looking rig AK, can you share details of the build, particularly the shaker you used? That configuration is a little more common, one can use a skid steer or tractor/loader to load and unload it. I'm wanting something like that little red jigger we saw earlier, so that I can use a skid or a mini excavator to load it. (Right now I don't have a skid, so either a mini or larger excavator would be the loading method of choice.)

However, I like the idea of the car coil springs, cheap, readily available, and should be more than hefty enough. If I make the screen longer and narrower, with a hopper underneath and a conveyor to take the dirt away and stack it, I'd be all set.
