Overpass bottom deicing device

An ice removing device at the bottom of an overpass belongs to the technical field of road maintenance equipment, and particularly comprises an ice breaking wheel, a collecting tank, an ice crushing device, a conveying channel, an ice melting box and a calandria, ice at the bottom of the flyover is broken by an ice breaking wheel mounted in the collecting tank; falling into collection tank, the ice piton is prevented from falling from high altitude, enters the ice melting box through the conveying channel, is rolled into ice chips by the ice crushing device, is subjected to hot melting, and isdischarged out of the device through the discharge pipe, so that the problem that a large amount of ice blocks are stored in the deicing device for high-vacuum operation is solved, and the situationthat the whole device collapses due to heavy head and light foot is avoided. In addition, ice blocks are rolled into ice chips through the ice crushing device, so that hot melting of the ice blocks can be accelerated, and cont
