I would think the Lawn mower example is one of the easiest ways to implament this. If you compressor motor is running constantly at a fixed speed you should be able to use it as you locomotion source. Add a shaft driven by another belt from the motor. Make it a fixed distance, but have it swing down and engage the wheels for power. Use that motion to turn on/off the sprayer. If you want variable speed, use a variable speed belt setup (pully sides seperate to change pully diamater/speed) and use the pully sided motion to adjust your spray amount. Alternativly you may be able to use throttle for speed if the compressor can handle the changes in speed.
Simplified I know, but that seems to be the basis of what you want.
