Overwintering queen bee storage tank

The invention provides an overwintering queen bee storage tank, and relates to the technical field of bee breeding. An empty comb phenomenon occurs at the front part of a honeycomb in a beehive main body along consumption of overwintering feeds, so that the weight of the beehive main body is reduced, and the gravity center of a beehive shifts backwards; by virtue of an elasticity adjusting device,the front part of the beehive is slowly ascended, the beehive main body in a horizontal state inclines to present a gradually descending state, and a sliding component moves backwards above the beehive main body along the horizontal direction to drive a multi-chamber queen cage to move backwards towards the honeycomb, so that the multi-chamber queen cage is located in the center of bee groups allthe time, and the phenomenon that a queen bee dies due to freezing and starving is avoided; by virtue of the technique, the beehive can be used for storing multiple queen bees during overwintering, can meet a demand on requee
