Solo mining on 3 workers

I have question about solo mining.
I have there workers each one have 1000mh/s.
If i mine solo - block will be divided to these 3 workers so my hashrate will be a sum of these there workers, or solo mining means that each worker will work on their own block??


I guess it means that you can solo mine in a pool, you get distributed shares, you take everything if you “win”, but you will not get a piece of the reward from the block the pool finds.

@autolyckost right that explains solo mining vs pool mining.
However I am also interested in the question as to whether the node ‘merges’ the hashrate of the three workers so that it works as the sum of three workers, or if it works like 3 workers working at each individual rate
