conveyor project

[rasorbackq]

My other project I am working on is a conveyor belt.
I bought this conveyor last week . Its 13' long and 10" wide.
Was told it came from a rental place that rented it out to assist to move dirt from basements. I want to use it to load firewood into my truck.
My problem so far is I don't know what size motor I need to run it.
So far I released the belt tension so the roller has very little tension on it. It does turn freely but does turn by hand with a bit of effort.
I tried a 3450rpm .75hp with a small pulley but it just hummed.
Next I tried a 1/4 hp 1725 and it just hummed.
Then I tried a 1/2hp 1725 It turned the roller only if I assisted and then would stop after 4-5 turns of the roller. Remember the belt is not turning yet.

Each of the motors had a 2" pulley on the shaft .
Any suggestion!!
Not sure if it need a gas engine to run it or just a motor.
Some of the hay elevators I has seen run with a belt and pulley. Was thinking maybe I need a gear and chain once I get the power issue working.

All thoughts are welcome.

I suspect you would want to use a reduction gear box like perhaps 60/1 or even 100/1.

It looks like the belt drive roller is about 4" diameter? That would mean that the belt will move approximately 1 foot for each revolution of the roller. With a 1725 rpm motor and 100/1 reduction your belt would move about 17.5 ft/minute.

It definitely needs a reduction drive, if it was possible to run as depicted in photo 4 it would be running at nearly 9 fps and be more like a firewood launcher.

Was just thinking about a jack shaft. Off the motor with a 2 "(A) sprocket via chain to a 12" (B) sprocket. 12 " sprocket is jack shaft on the other end is a 2"(C) sprocket to the conveyor sprocket of 6"(D)

Math is [A x C] divided by (B x D) x motor speed.
2 x2 / 12 x 6 x 1725
4/ 72 x 1725
= 95rpm

And if you used a 100/1 you could most likely drive the system with a 1/4hp electric motor.

What I could do was try a few pieces of firewood and then park the truck there Hopefully most will land in the truck.

6" roller aprox 19 " around the rolling edge

95rpm x 19" =1805 running inches
13 Ft belt x 2 top and bottom x 12 "= 312 inches = 5.78 rpm

Ok really new to me is chain size. I have #35, #40, #41 and #50 What is the recommended size?
