On the horn-like surface of described central tube and be provided with respectively the through hole of different pore size on the blade of back taper portion, be beneficial to input and output material.
Beneficial effect of the present invention is:
1, the non-isogonism logarithm helical blade design of unique concave surface, an end curved surface is comparatively mild, and it is recessed that other end curved surface is arc; Play three-dimensional stirring action, fine solution aggregate segregation, stir a unequal difficult problem;
2, root of blade is L-type, increases its loaded area, more firm with inner tank wall welding;
3, vane tip welds wear-resisting round steel, plays wear-resisting reinforcement effect, in whipping process, concrete is played to secondary agitation effect simultaneously, makes concrete-agitating more even; Root of blade coordinates and makes leaf cross-section be unique matrix with round steel on vane tip, realizes three-dimensional agitating function;
4, in inner cone, establish a pair of stirring blade, improve whole whipping performance, solved aggregate segregation problem;
5, the through hole of establishing different pore size and quantity on the blade in rear cone and central tube, makes tank body input and output material more smooth and easy;
6, a pair of streamlined back blades, accelerates discharging speed effectively, and plays the effect of shunting material.
