After a search for early and vintage line marking machines, I couldn't find anything that would make me think this was for designed for line marking.
Given the adjustable crank setup, I think it's for dosing something, maybe controlling the mixing ratio of something?
I agree with the thoughts about it could be a friction drive, there doesn't look like enough room for a belt, unless the belt doesn't go through the gap?

Its been suggested that this is from an older style sugar cane planter. The 'seed' from which sugar cane is grown is..... short lengths of sugar cane.
Somewhere above this device someone would have been feeding sugar cane stalk into a cutter that reduced it to short pieces which then fed into the hopper to he right of the paddles/buckets. The paddles/buckets picked the pieces up one at a time and dropped them into the furrow at intervals determined by the setting of the eccentric.
I don't know if this is correct or not but its the most plausible explanation so far.

Not sure thats it. Though I'd hate to say that couldn't be it and for the reason I'm about to give I'm having trouble coming up with anything better.
The best I can see you you can do feed wise is something like 2 sectors per turn of the wheel (both in half a rev of the wheel, nothing in the other half), 1 sector per turn of the wheel. 1 sector every two turns of the wheel. Not exactly "adjustable". If you were feeding big single items wouldn't you have less teeth on ratchet? so many teeth would mean sooner or lather you'd feed nothing or double.
So my guess it a powder with part of a sector each turn........though that doesnt really get us any closer.

I reckon this device sat on a type of plough that dug a farrow while the machine in question dropped potatoes into the preceding farrow.
It's as good as anyone else's guess.
Surely some old timer out there can put an end to this mystery.

Perhaps its not a farm piece at all.
Maybe the Main Roads museum up in Toowoomba might recognise it ?

I have taken the liberty of copying the photographs. Would it be OK with the original poster for me to email them to our club members. (Dunmunkle Sump Oilers Machinery Preservation Inc) to see if any of them can work it out?
Don't want to do so until I get the OK.
Regards,
John

Those pictures make it clearer. I think the best idea so far is from Combustor.
It was certainly made to feed some kind of granulated material, (seed maybe?) at a controlled rate into a processor, perhaps a screen, crusher or grinder.
The front edge section where the product is ejected, seems to be angled upwards and has a lip on it. Both of these would seem to work against the smooth unobstructed flow of product.
The paddle wheel also seems confusing. It may just be the angle of the camera, but in the third picture from todays offering the 2 paddles on top seem to be off line from the axle. Probably they just form a bucket together.
One idea that popped into my head is a grain pickling device. I don't know if this is the right term, but it is what was used when I was staying at a friends farm when I was very young. They were feeding a pinkish powder into the grain passing thru an auger. It was to protect the grain from insect damage. This grain was being kept for later seeding. The mechanism they used was a hole in the top of the auger with a bit of galv pipe welded around it and a spoon.

I would suspect powder would likely pack up a bit in that design. Unless the unit were hard mounted to a shaker.

This is probably way out of the ball park, but seeing as it is mounted to a bench of some description and run from a flat belt, I'm going to say it was for making some sort of brick, (fireplace or similar), where different sizes were required, hence the adjustable arm. The size of the paddles, rules out grains etc.
