As improvement of the present invention, described feeding rotation section is made up of the two feeding linking arms that splice mutually, the splice ends of described feeding linking arm cooperatively interacts and forms the rectangular pilot hole in a cross section, and the other end of described feeding linking arm is connected with inside and outside screwfeed unit respectively; The described rotation section of returning is made up of two linking arms that return that splice mutually, and the described splice ends of returning linking arm cooperatively interacts and forms the rectangular pilot hole in a cross section, and the described other end that returns linking arm returns the unit with inside and outside spiral respectively and is connected.
As a further improvement on the present invention, described inside spin feed unit comprises interconnective interior feed shaft and interior feeding blade group, and feeding blade group is spliced by feeding blades in a plurality of in this; The external spiral feed unit comprises interconnective outer feed shaft and outer feeding blade group, and this outer feeding blade group is spliced by a plurality of outer feeding blades; Described inside spin return the unit comprise return in interconnective axle and in return vane group, return vane group in this and be spliced by returning blade in a plurality of; Described external spiral returns the unit and comprises and interconnectively outer return axle and return vane group outward, and this is outer to return vane group and returned blade and be spliced outward by a plurality of.
Further improve as of the present invention, the described inside and outside feed shaft and the inside and outside back side of returning axle all are equipped with angle steel, and described angle steel is made up of three orthogonal legs.
As improvement of the present invention, described contiguous block is sickleshaped.
By the above-mentioned description of this invention as can be known, compare, the invention has the advantages that with prior art:
1, external spiral returns unit and external spiral feed unit and is subjected to force direction opposite when stirring, they are main mixing power generations place simultaneously, by contiguous block external spiral being returned unit, external spiral feed unit, inside spin feed unit and inside spin returns the unit and couples together, the interaction force of agitating device is cancelled each other, thereby greatly reduced the stress deformation of agitating device.
2, contiguous block not only plays the connection effect, and sickle-shaped design simultaneously can also effectively prevent the concrete seize.
3, because each unit of agitating device shape in the shape of a spiral, so material is more smooth and easy when stirring, the stirring efficiency height.
4, by the setting of angle steel, can the bolt of locking-blade be shielded, and prevent that bolt is worn.
