"There are no sensors or anything I could use" A timer will be at best cumbersome, and it is a "dumb" control in that it doesn't have any information about the desired result. If activated when the bin is almost full, it'll overfill the small tank. I prefer the data driven approach. I'd add a sensor. A capacitive prox sensor seems ideal for this application.
