There is no such adapter available and you do not want to even attempt to do what you are talking about unless you want to damage the electrical system in your RV or your home or even catching your home or RV on fire.
I am not going to go into all of the technical details as to why this should not be done other than to tell you that the wiring configurations on your Dryer electrical connection and your RV electrical connection are not compatible and you could even end up running 220 volts through your RV's electrical system which will definitely cause problems.
You have two choices here you can either hire an electrician to wire your house for a proper 30 Amp RV connection or use a 30 Amp female to 15 Amp Male Adapter to plug into one of your homes 15 Amp Outlets.
If you use a 30 to 15 Amp Adapter you will be limited on the number of appliances that you can run at the same time in the RV. For further information on these limitations you should read the answer I gave to Can I Plug In A RV To A Home Electrical System?
