Working on Design for Grizzly Vibrator. Input appreciated!

[kg7il]

My design goals are:
Minimal Material
Minimal Cutting: No Complex Cuts. Straight Cuts Only.
Separate Large Rocks using Grizzly Bar
Provide for interchangeable Screens for sizing.
Easy to disassemble for moving with loader / tractor
Provide for various 'shaker / vibration' methods.


I don't have much more in writing except these pics.

The OVERVIEWS IN BOLD should be sufficient, but detail views included.

OK I will bite... What in "heck" is a Grizzley?

What do I win?

 

[k0ua]

Well OK.. I guess it is some sort of rock seperator... but Grizzly? never heard of that.

....but Grizzly? never heard of that.

Quite a common name actually, or it is around here anyway .
What do you plan on using for the shaker part, an eccentric weight or something else. I didn't see that part on your sketches.....Mike

I have a home made (by someone else) grizzley, non vibrating. I find that the angle needs to be at about 45° to shed the bigger stones without piling up. The spacing on my bars is about 3". It makes decent gravel but a secondary shaker would be nice for a finer, better (graded.sized) end product. It looks like you might be planning on using expanded metal for your screen. A friend has a small EZ screen? and has experemented with expanded metal with poor results. It is just not heavy enough and the commercially made screen seem to be worth it.
Keep us updated.:thumbsup:

It's common name for me
and a few others.

Now on to the other items.

MrMikey:
My notes indicate that I am still working on the vibrator mechanism.
I have several design ideas.
1) a spiral wheel that compresses the springs during 359 degrees and pops it loose at 0/360 degrees. Maybe this will launch a few stones.
2) an eccentric driven by a longer belt that is concentric or coaxial with the wheel axle to eliminate belt length variation.
3) a crank shaft on the lower frame that has an adjustable connecting rod to the grizzly. (there is that word again).

RustyIron
Hopefully I can use it non vibrating with the adjustable arms at full length to achieve about 45 degrees.
When vibrating, I think I can come down quite a bit.

The inverted angle iron would create the main grizzly. I would like to have several screens (expanded metal) welded on the upper edge to another angle iron that can be fastened at this upper edge to the grizzly frame. This approach means that in a run, all material would pass through the equivalent of a single sized screen.

I would like to have a finer screen below the grizzly bar with a means of further separating the materials, but this mostly likely would complicate the frame. Open to ideas tho'.

Check the link out, my buddy just bought one and loves it, i think he said it was abut $3500.00. I'm not saying you cant build your own, but if you had the money and not the time, this may fit the bill...OMH Proscreen - SLG-78

but if you had the money and not the time,

I'm retired; I have neither.

Looks great, but more than my wife would let me spend. Heck, it's more than I would spend.

My brother-in-law (BIL) provided me with a pick up truck load of steel.
Mostly 1.5" angle, 2.0" angle, 1 inch tube, 2 inch tube, 1" strap, 2" strap.
Plenty in 8 foot lengths, some 10' and many shorter ones.

I won't be spending a cent on steel.

Another design goal is to use my available material and a roll of self-shielded Wire Feed 035

I learn new things all the time!

That's why I like forums. Chickens, Tractors, Guns, Gold, Bees, Ham Radio, Woodworking, Welding, Forestry, Home Inspection, Boats, Truckers, Electronics and a few more.

Why just this morning, I learned I spend too much time on the forums.
