STIRRING BLADE DEVICE

PROBLEM TO BE SOLVED: To facilitate generation of an upstream and a downstream without forming a stirring blade helically, and thereby facilitate the manufacture of the stirring blade device by installing a pair of blade supporting members extended in an orthogonal plate to a rotary shaft, on the rotary shaft and attaching a plate-like stirring blade obliquely between the blade supporting members. SOLUTION: A stirring blade device 1 is used for stirring a paint or foods in a tank when manufacture these products, and is composed of a rotary shaft 4, an upper and a lower blade support beam 5, 6 and a pair of stirring blades 7, 8. Both blade supporting beams 5, 6 are formed in sach a state that the beams are extended on an orthogonal plate to the axial core direction 10 of the rotary shift 4. These blade support beams 5, 6 are installed in such a manner that the angle formed by the beams is 90 deg.C as viewed on the plan. In addition, each of the stirring blades 7, 8 are installed in such a way that both upper and lower end parts are tilted at same angle (e.g. 45 deg.) with the center shafts 11, 12 of each of the blade support breams 5, 6 within an orthogonal plane to the axial core direction 10 of the rotary shaft 4, and at the same time, are tilted with an orthogonal plane to the axial core direction 10.
