homemade auger feed coal bin

homemade auger feed coal bin

PostBy: syncmaster On: Wed Aug 20, 2008 4:44 pm

I am very surprised I posted my coal bin delivery, posted all kinds of pictures and no one picked up on the fact that there is no place to get the coal out other than reaching thru the top and shoveling it into a bucket.
here is the link on the delivery:
6 ton rice coal delivery thru garage door to bin

At first I thought maybe poke a 8"hole in the foundation wall and install a angled 8" stove pipe and get the coal out by gravity , but then I started trying to design a door that I could control it and I thought if I could use a auger I could just turn the auger off and stop the flow and also I thought I would get a better flow.

So I made a auger system with stuff I had around I'll post pictures below.

holding a bucket under it and running it for 30 seconds and weigh the bucket minus the bucket weight it delivers .7 lbs per second. so if you are going to fill a 280lb hopper (I have a VF3000) with about 200lbs of coal will take 4 to 5 min.

I think the will work...right now I will be happy to get the VF3000 installed... trying to get all the stuff together.

below is a closup shot holding the camera inside the stovepipe T

After I get the boiler installed and start loading with the auger I am thinking maybe I can supply 15v to the 12v motor and increase the speed a little.


hope this helps you guys!!!

That's prettty cool. But be prepared to run it longer, the VF3K holds 250#.

Not such a bad idea but that pipe isn't going to last that long between the friction of the auger and the corrosion caused by the coal. I'll give it 4 or 5 years tops. ;) As a comparison some of the thicker steel pipes used on boilers like my Van-Wert I've seen rot out on the end where it's in the coal constantly in about 30 years. They are about 3/16 inch thick if not more.

I guess that is ground auger? What happens if it jams?

well, in 4 or 5 years we will be drilling off coney island and the new jersey shore.
We will have so much oil that fuel oil will be 25cents a gallon so I will switch my VF3000 to the oil gun.

If the auger jams it has a dc motor so I can reverse it and if that dosen't work I could put a 36" pipe wrench on the auger shaft and coax it a little. It is a 8" auger I doubt something will jam it.

I mean if it jams are you going to start breaking stuff? For example the augers on the boilers have brass or copper shear pins. They are geared so low something is going to break if there was jam in the auger. The shear pin will simply snap before anything else since its the weakest link. Either the worm, transmission or something else is going to break if they weren't there. I'm just asking because I never used the tool you posted. Actually curious because I'd imagine something like that could be dangerous when used for digging post holes if it got caught on a root or rock.

I have experience in this area. :oops: My dad has a old ?1/2 horsepower? Craftsman drill and I was drilling into a stump with it. This has the lock so you can lock the trigger on. The damn thing got stuck and nearly tore my arms off, I went sailing like superman. Round and round she went until the cord pulled out of the wall. :lol:

I see what you mean.... when the auger was used for post holes it has a clutch that stops applying power when you hit a root.
but over time the clutch safety cuts in all the time making the thing pretty usless.

But you bring up a good point, I could measure the current of the 12v motor and put a fuse inline with it, so if the auger gets stuck the motor current would increase and blow the fuse. this would also keep me from burning out the motor.

Thanks for the idea, Richard !

that thing is VERY cool!

Now are you going to install the VF3000 directly below that shoot? :D

Next, add a second :D auger to take out the ashes for you!!

Yes, I will connect a 8" x 2ft stove pipe into the 8" T and the other end into the VF3000 hopper.

I was thinking about putting a photo Eye in the hopper so when the hopper gets low the photo eye gets uncovered and it could send a signal to trun on the auger, and it could fill automaticly.
But then I thought I have to remove the ashes every 3 days so I might as well flip the switch to fill the hopper.

Now I am giving alot of thought to the ashes..... there has to be a way....


I'll post more pictures when I get it all set up.

Ultrasonic level sensors are the way to go with dry material in a bin or hopper. A photoeye might have problems with the coal dust on the optics.

I don't mind filling the hopper, its emptying the ash bin that really sucks.

I applaud your inventiveness!

Using a 1/2" angle drill contersinking holes into 4 X 4's with a 2" self feed drill... it jammed, twisted against my leg, and as doing so the "stay on" button got pushed so when I released the trigger it didn't stop. It is electrically stalled putting 11 million pounds of pressure between my arms & leg & 4 x 4. The wife was nearby and she heard me yelling "unplug it unplug it unplug it unplug it...."

Thats similar to how my guy delivers mine, he has a 5"? x 14' auger in a stainless pipe and can shoot it right into my bin thru the window. It takes about 45 mins to unload 4-5 tons.

Only thing, with the thin wall pipe, it may rub and wear thru fast, but great idea!

**** update on this project ****

I got my Vf3000 installed and went to use my auger loading system.
I was surprised to see how much coal dust I got from it falling 2ft into the hopper.
see picture below.

this was my first try...but was too dusty

I made a metal cover to go over the hopper and cut a 2" hole so I could hook up a shop vac while I am filling the hopper.

here you can see the 2" hole for the shop vac hose.

So when I am filling the hopper I will connect a shop vac to suck up the coal dust.... it works fine like this.

This set up works good.... If I was going to do it again I would use a 8 or 10 RPM motor instead of a 4RPM that I have now.

this system... 8" earth auger and 4 RPM motor delivers 40lbs /min
