Claim 6:
7. A shot blasting cabinet with adjustable impellers, comprising:
the cabinet having an inlet and an outlet, a shot-blasting working line being defined between the inlet and the outlet;
a plurality of impeller apparatuses disposed symmetrically on an upper side and a lower side of the cabinet, wherein each of the impeller apparatuses has a protective housing, a driving device, a pair of rotary plates, and a plurality of impeller blades, the impeller blades are connected radially between the pair of rotary plates, and the driving device connects to one of the rotary plates, and wherein the protective housing has a first baffle and a second baffle, the protective housing covers the pair of rotary plates and the impeller blades, a shot-blasting exit surface is defined in the protective housing, and the shot-blasting exit surface communicates with an interior of the cabinet; and
a plurality of adjusting devices arranged correspondingly to the impeller apparatuses, each of the adjusting devices being configured to adjust an angle and a distance of the shot-blasting exit surface relative to the shot-blasting working line, so that the shot-blasting exit surfaces of the impeller apparatuses are configured to have different angles and heights;
wherein the first adjusting unit and the second adjusting unit each have a traverse moving member, the traverse moving member forms a bevel, the bevel abuts against bottom ends of two sides of the protective housing, the traverse moving member is capable of moving relative to the impeller apparatus so as to lift up or lower the impeller apparatus.
