Yes. Assuming everything is wired correctly and your 30 amp AC cord is compatible with your 50 amp plug, you can do this. I think you will find, however, that your 50 amp plug has a different pin configuration than your 30 amp cord end. This is not easily resolved because there are serious dangers in going the other direction, plugging a 50 amp appliance into a 30 amp receptacle.

No there are no adapters made for these types of installations. The reason there are no adapters is to provide a factor of safety. To plug a 30 amp plug into a 50 amp receptacle could allow 50 amps to be applied to a 30 amp rated cord. The 50 amp receptacle is more than likely being fed by a 40 amp breaker. Just change the plug cord to match the ampacity of the breaker ahead of the 50 amp receptacle. Or change the 50 amp receptacle and 40 amp breaker to a 30 amp breaker and use your existing cord plug.
