Abstract

PURPOSE: To prevent effectively scattering of powder by reducing the pressure of dusty gas rising in a construction of hollow hood installed over the hopper to introduce the dusty gas in this hollow, in which a stream interference preventive plate is provided.
CONSTITUTION: A hollow hood 9 is installed on the upper end of the hopper 1, with a size enough to enclose the grab bucket 2. This hollow hood 9 is provided with a peripheral hollow part 8a having its opening 8 to below and with a stream interference preventive plate 10 dividing the hollow 8a in the vertical direction. This stream interference preventive plate 10 is provided with depressurizing holes 13. The use of this dust protection hood permits the wind W to pass over the grab bucket 2 along the stream line V and thereby hinders the wind from intruding into the inside 14. The rising streams A, B in the hopper which has intruded into the spaces 11, 12, are depressurized by the depressurizing holes 13, so that dusty gas never blows out reversely.
