The invention discloses a garbage storage bin leachate guiding device based on a hyperbolic screen drum. The garbage storage bin leachate guiding device comprises a driver (1), a hyperbolic screen drum assembly (2), an integrated frame (4) and a baffle (9); the hyperbolic screen drum assembly (2) comprises a hyperbolic screen drum (21), a long shaft (22) and a pair of bearing seats (23); the drumshape of the hyperbolic screen drum (21) is of a hyperbolic cambered surface structure, and a plurality of flow guide through holes (216) and a plurality of blades (212) are distributed on the hyperbolic screen drum (21). When the hyperbolic screen drum rotates, garbage can be mashed through the blades; garbage movement in a local area of a storage bin is triggered; landfill leachate is effectively guided through the conical flow guide through holes, efficient and smooth flow guide is guaranteed, inconvenience and potential safety hazards of manual dredging are avoided, the labor cost and theworking intensity are reduced, and the device has the advantages of being simple in structure, convenient to maintain, safe and reliable in operation and the like, and is suitable for leachate flow guide of a domestic garbage incineration power plant (field) garbage storage bin.
