A great way to separate rock from dirt. It's perfect for gardens or in my case landscape rock!
I needed to install a french drain to redirect the rain from the front of my house. The problem was that my house is surrounded by rock beds! I ended up building a powered wheelbarrow trommel to save me from separating the river rock from the good dirt by hand. The trommel will also come in handy for getting all those pesky rocks from my wife's garden. The most novel thing about it is that the trommel sits on top of my wheel barrel so that dirt is dispensed right in the wheelbarrow for easy transportation. Oh, and I built the thing for less than 90.00.
If you'd like to build one for yourself, you'll have to make up the dimensions as you custom fit the frame for your wheelbarrow.
Specs for the basic parts
Gear reduction motor (125 rpm, 1/10hp, 12v, 12 amp)
I used a 3/4 inch pully with 5/8 inch bore, but any size pulley will work.
10 amp manual battery charger
1/4 inch wire mesh screen from any hardware store
The tops of three 5 gallon buckets (two for wheel tracks and one for pulley)
8 castor wheals that fit in the track of the bucket rims.
Rubber floor mat
If you are going to use a garbage can to catch the rocks as they come out of the trommel, you'll find that the wheelbarrow will tip backwards. I shifted my wheelbarrow's legs back 6 inches. The easiest way to keep the cross plate that gives the legs their stability is to turn the legs around before remounting them.
If you'd like to save 15 or so dollars you could forgo the mesh screen and bolt two 5 gallon buckets together and then drill "a lot* of 5/16 in holes in buckets to simulate a screen. It works. I tried it, but it won't perform as well as the mess screen.
Get a wheelbarrow with two wheels! I overloaded the wheelbarrow a few times and almost it.
