The utility model relates to the technical field of unloading equipment, and particularly discloses a low-dust
powder unloading device. Comprising a trench, a lifting supporting plate, a hydraulic lifting mechanism, an
awning, a spraying device, a screw conveying groove and a
belt conveyor. A hydraulic lifting mechanism is installed in the trench, a lifting supporting plate is movably arranged at the upper end of the trench and comprises a plate body and a
fixed hinge, the
fixed hinge is fixedly arranged on the side wall of one end of the trench, one side end edge of the plate body is hinged to the
fixed hinge, and the telescopic end of a lifting hydraulic rod of the hydraulic lifting mechanism is hinged to the bottom of the plate body. A screw conveying groove is formed in one side, provided with the fixed hinge, of the trench; the vehicle is obliquely lifted through the lifting supporting plate and the hydraulic lifting mechanism, so that
powder loaded in the vehicle hopper falls into a rear screw conveying groove and then is conveyed out through a
belt conveyor, and manual unloading is not needed; meanwhile, the
awning is further arranged to prevent flying dust from diffusing, and the spraying device is arranged at the top of the
awning to achieve the dust falling effect.
