At present, the application of the portal crane in unloading bulk materials (such as iron ores, coal and the like) is very wide, the characteristic of strong universality of unloading materials is also considered when a user selects the portal crane, but how to efficiently and environmentally unload high-viscosity powdery bulk materials is still a difficult problem of port machinery.

A bulk material hopper is used as a material receiving and transferring device of a portal crane, and good flowability of materials is usually ensured by adopting a proper hopper wall angle and a hopper wall vibrator; the impact force of the materials is reduced through the common grating and the buffer beam; raise dust is reduced through a wind-break wall and a water sprinkling and dust removing system.

When high-viscosity powdery materials are unloaded, the materials are easy to agglomerate and adhere to the hopper wall after being damped due to small granularity (micron order) and high viscosity of the materials; the normal flow of materials cannot be ensured by the common hopper wall angle and the configuration of the hopper wall vibrator, and the sprinkling and dust removal are not more suitable for the materials of the type; this type of material is also characterised by a high density, generally of 2.0t/m³The impact load is large when the material falls; the common grating and the buffer beam reduce the passing space of materials, so that the phenomenon of material accumulation is worsened.
