MOBILE DISCHARGE DEVICE FOR POWDER AND GRANULAR MATERIAL STORAGE SILO AND POWDER AND GRANULAR MATERIAL STORAGE SILO

摘要

A movable discharge device (1) for use in a particle/bulk material storage silo includes: a travel body (10) configured to travel along a groove (103) provided at a lower portion of a storage silo (101); a scrape-out unit (20) configured to move integrally with the travel body(10) and including a blade (21) configured to rotate above the groove (103) to rake coals (106) in the storage silo (101) and scrape out the coals (106) to the groove (103); and a groove closing mechanism (50) configured to close a predetermined region of the groove (103) within a rotation trajectory region of the blade (21). The discharge device (1) is configured to be able to suppress the change in the discharge amount of coals (106) discharged by the blade (21) from the particle/bulk material storage silo (101).
