Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:

As shown in Figure 2, the preferred embodiment of the mixing blade unit 100 of the present invention is suitable to be installed on a rotating shaft 210 of a stirring device 200, and the rotating shaft 210 takes an axis L as the center of rotation toward a first direction I and A second direction II that is opposite to the first direction I rotates. The stirring device 200 also has a housing 230 that defines a chamber 220. The housing 230 has a material inlet 240 located at the top, a set A discharge pipe 250 at the bottom and a discharge port 260 at the side. As shown in Fig. 3, Fig. 4 and Fig. 5, the agitating blade unit 100 includes a shaft seat 10 fixed on the rotating shaft 210, a plurality of positioning arms 20 extending from the shaft seat 10, a plurality of The vane set 30 fixed on the positioning arm 20 and a toggle member 40 fixed on the bottom of the shaft seat 10 .

The shaft seat 10 is fixed on the bottom of the rotating shaft 210 and has an outer peripheral surface 11 surrounding the axis L. As shown in FIG.

The positioning arms 20 are radial and extend outward from the shaft seat 10, and each has an inner end 21 fixed on the outer peripheral surface 11, and an inner end 21 opposite to the inner end 21 along the longitudinal direction. An outer end 22 of the outer end 22, a first side edge 23 extending from the inner end 21 to the outer end 22 and facing the first direction I, a side edge 23 facing away from the first direction I and facing the second direction II The second side edge 24 and a bottom surface 25 between the first and second side edges 23 , 24 , the long direction of the positioning arm 20 corresponds to the radial direction of the shaft seat 10 .

The blade sets 30 each have a base plate 31 fixed on the bottom surface 25 of the positioning arm 20 and a plurality of blades 32 connected to the base plate 31 . The base plate 31 extends along the long direction, and the blades 32 are arranged at equal intervals along the long direction, and each has a connecting end portion 321 connected to the base plate 31, a terminal portion 322 opposite to the connecting end portion 321, A curved portion 323 between the connecting end portion 321 and the end portion 322 , two inclined edges 324 and an end edge 325 connected to the bottom of the edges 324 . The end portion 322 extends downwards from the first side edge 23 toward the first direction I, the curved portion 323 is recessed in the second direction II compared with the connecting end portion 321 and the end portion 322, and An obtuse angle is sandwiched between the connecting end portion 321 and the terminal portion 322. When the edge 324 extends from the connecting end portion 321 toward the terminal portion 322, it gradually extends inwardly, and the end edge 325 is outwardly convex. arc.

The driving member 40 has a connecting rod 41 fixed on the bottom of the shaft seat 10 and extending along the axis L, and a driving rod 42 vertically fixed on the bottom of the connecting rod 41. Between the positioning arms 20 and in an S-shape.

As shown in FIGS. 3 and 5 , when the stirring blade unit 100 is driven by the rotating shaft 210 to rotate toward the first direction I, the end portion 322 of the blade 32 is used to move from the first side edge 23 toward the first direction I. direction I and extend downwards, and stir the solid and liquid materials contained in the chamber 220 of the housing 230. In addition, when the edge 324 is used to extend from the connecting end 321 to the end 322, relatively Gradually extending inwardly, and the end edge 325 is in a convex arc shape, so that when the blade 32 moves the solid material, it can produce a smoother pushing and shoveling action. And when the stirring blade unit 100 is driven by the rotating shaft 210 to rotate in the second direction II, the end portion 322 of the blade 32 is used to extend obliquely to the bending portion 323 to achieve the effect of smoothing the solid material, which is helpful The solid material is leveled, compacted and easily taken out. Moreover, when the stirring blade unit 100 is driven by the rotating shaft 210 to rotate toward the first and second directions I and II, the driving member 40 will push the solid material toward the direction in which the blades 32 are arranged, so as to avoid stacking of the solid material. in the middle of the chamber 220 .
