Abstract
The invention discloses an unloading mechanism for storage of bulk solids with thick fluidity, which solves the problems that current bulk solid unloading mechanisms are complex in structure and the unloading and transmission mechanism is difficult to maintain. The unloading mechanism for storage of bulk solids with thick fluidity comprises a central cone body (27) and a revolution platform (19). A combined curve unloading scraper (25) and a swallow-tail unloading assistant scraper (26) are arranged on the bottom surface of the revolution platform (19). A rotary shaft (1) of the combined curve unloading scraper (25) is connected with an output shaft of a hydraulic motor (24) on the top surface of the revolution platform (19). Two hydraulic cylinders are fixedly arranged on a same side surface of the revolution platform (19) respectively. A circular ratchet wheel matrix (13) is arranged inside a circular hole on the bottom surface of the central cone body (27). The ends of piston rods of the two hydraulic cylinders are connected moveably with a ratchet-like gear tooth (14) on the circular ratchet wheel matrix (13). Revolution of the revolution platform (19) is implemented under control of the hydraulic cylinders driving a hydraulic station (20). The unloading mechanism ensures the bulk solids which are first-in and first-out and guarantees the smoothness of the unloading process.
