The connection between the arch breaking main shaft 5-3 and the hopper body 3 is sealed by a removable sealing gland, and the arch breaking main shaft 5-3 is sealed by a packing, so as to avoid the direct contact between the material seepage and the material in the hopper body 3, and facilitate maintenance. The arch breaking main shaft 5-3 is driven by the first motor 5-1 to rotate circumferentially, and the arch breaking blades 5-4 on the arch breaking main shaft 5-3 rotate together with the arch breaking main shaft 5-3 to prevent the material from arching in the hopper.
[0026] The conveying mechanism 7 comprises two groups of second motors 7-1, each group of second motors 7-1 is connected with a second speed reducer 7-2 through a key, each group of second speed reducers 7-2 is connected with a first pushing main shaft 7-3 through a shaft coupling, each first pushing main shaft 7-3 is engaged with a second pushing main shaft 7-5 through a gear, each first pushing main shaft 7-3 is symmetrically provided with first pushing screws 7-4 with opposite screw directions, and each second pushing main shaft 7-5 is symmetrically provided with second pushing screws 7-6 with opposite screw directions.
