The utility model discloses a sealable material guide funnel and relates to a material guide funnel used for transferring materials such as ores and waste rocks through a vibratory ore-drawing machine, loading the materials into transportation devices such as trains and vehicles, and discharging the materials to a discharging chute well. The sealable material guide funnel is structurally characterized by comprising a funnel framework, funnel bottom plates used for rotating inwards oppositely to be closed together and sealing a discharging hole of the material guide funnel, funnel bottom plate lifting rods movably fixed on the two funnel bottom plates, and a lifting rod control device. The sealable material guide funnel can be used for effectively solving the problem that the size of the funnel opening of the fixed funnel cannot be adjusted; the materials such as the ores can be accurately loaded into device containers, thereby preventing the materials from scattering and influencing the operation of the device; meanwhile, the artificial cleaning is also avoided; the labor intensity is reduced; the sealable material guide funnel can be sealed after discharging the ores in the winter, so that the phenomenon that the materials such water-containing ores and the vibratory ore-drawing machine freeze can be effectively avoided; the material guide funnel can be made of profile steel material and is simple to process and manufacture and convenient to operate.
