Hand made miniature wood waterwheel machine?

I don't know what to call it but I bought it. It is 9" long and 7" tall
All made of wood with no nails. Moving wheel inside with metal crank. Asian writing and I'm not sure Japanese or Chinese or?
Anyone know what it might be?

I think bamboo, rather than wood.

 

I think so. Thanks.

 

Looks like a Japanese/Chinese rice thresher.

 

Maybe meant to be in a garden, with water flowing into it and then on into a little pond? Just a guess!

 

Looks like a mini sluice box.

Edit: Found this one with a different feeder.

That's what it is Wow thanks anund!!

 

It's a wind-winnowing machine,just though thresher for some reason.

 

Now I see it Thanks Hollyblue. saw some antique photographs of one.

 

But being from Colorado and the seller in the link I posted is in Utah, of course we thought it a sluice.

 

Being from California I thought the same thing.

 

But it really didn't look like a wet or dry gold sluice.

 

No, more like a wash plant.

 

old hand-mill ?

 

So is the writing Japanese or Chinese?

 

I wonder whether it's a toy? Or something else?

 

Maybe @Asian Fever can read the writing?

 

More a scale model than a toy I think.

 

Ok so Taiwan. And not much value. Glad I only paid 3 dollars. Lol
