The manufacture method of vane of mud agitator
Technical field
A manufacture method for vane of mud agitator, belongs to mud stirring apparatus field.
Background technology
Existing slurry mixer is vane type mostly, as application number: the mixer of 91202977.3, this rigid blade is on-stream when encountering stone, rock ballast, often occur that blade is by the phenomenon of card, because the blade of this kind of mixer is all rigid blade, the shaft also had is welded to connect with blade, so, suppress bad motor, Duan blade, not curved shaft or the accident damaging tank body happen occasionally.And this kind of mixer also bad angle of adjustment blade and the space between blade and inner tank wall.
Summary of the invention
Object of the present invention is the manufacture method that will provide a kind of vane of mud agitator, and the blade construction of this slurry mixer is connected to form by blade face, petiole and nut.The blade face spring steel plate of blade is made (that of autobody sheet is a kind of), and the front shape on blade face is the thick middle on the isosceles trapezoid of fillet, blade face, periphery is thin and steel is tough sharp, good springiness, improves the shearing force of blade in stirring with this, thus improves the operating efficiency of mixer.In the major part one end on blade face, the central longitudinal axis along blade face is provided with several holes, is connected for petiole.The thickness on blade face equals the average thickness on blade face herein.
Petiole is one section of cylinder, form by round steel car system, the diameter of petiole is greater than the interior thickness on blade face, at the middle part of petiole, longitudinally offer one section of draw-in groove, the width of draw-in groove can embed one section of blade face (one end in band silk hole), and the draw-in groove of petiole is provided with several holes, and this hole is corresponding with the silk hole be located on blade face.The one end (having a hole) on blade face is embedded in draw-in groove, in silk hole, inserts screw or rivet and fastening, one end of blade face and petiole is vertically connected integral.
Be provided with one section of screw thread at the other end of petiole, petiole can penetrate in the hole of shaft and (punch on shaft in advance), and petiole uses fastening nuts after penetrating the hole of shaft, and the blade face after fastening is fixed on shaft.Petiole can put pad, by the pad quantity between plus-minus blade face and shaft, the space between top, blade face and inner tank wall can be adjusted.By rotating the orientation on blade face, angle of inclination when blade face is stirred can be adjusted.The blade of this slurry mixer run into stone by card after, self can produce elastic deformation, thus continue after getting around stone to stir, avoid the infringement that rigid blade brings.When needing to change blade, unload the nut of petiole, very convenient.

Detailed description of the invention
As shown in Figure 1, 2, provide a kind of manufacture method of vane of mud agitator, the structure of this vane of mud agitator is connected to form by blade face 1, petiole 2 and nut 4.The blade face 1 of blade is made (that of autobody sheet is a kind of) with spring steel plate, and the front shape on blade face 1 is the thick middle on the isosceles trapezoid of fillet, blade face 1, and periphery is thin and steel is tough sharp, good springiness; Improve the shearing force of blade in stirring with this, thus improve the operating efficiency of mixer.In the major part one end on blade face 1, the central longitudinal axis along blade face 1 is provided with several holes 8, is connected for petiole 2.The thickness on blade face 1 equals the average thickness on blade face 1 herein.
Petiole 2 is one section of cylinder, form by round steel car system, the diameter of petiole 2 is greater than the interior thickness on blade face 1, at the middle part of petiole 2, longitudinally offer one section of draw-in groove 7, the width of draw-in groove 7 can embed one section of blade face 1 (one end in band silk hole), and the draw-in groove 7 of petiole 2 is provided with several holes 8, and this hole 8 is corresponding with the silk hole 8 be located on blade face 1.The one end (having a hole) on blade face 1 is embedded in draw-in groove 7, in silk hole 8, inserts screw or rivet and fastening, one end of blade face 1 and petiole 2 is vertically connected integral.
Be provided with one section of screw thread 3 at the other end of petiole 2, petiole 2 can penetrate in the hole of shaft 6 and (punch on shaft in advance), and petiole 2 is fastening with nut 4 after penetrating the hole of shaft 6, and the blade face 1 after fastening is fixed on shaft 6.Petiole 2 can put pad 5, by the quantity of the pad 5 between plus-minus blade face 1 and shaft 6, the space between top, blade face 1 and inner tank wall can be adjusted.By rotating the orientation on blade face 1, angle of inclination when blade face 1 is stirred can be adjusted.The blade of this slurry mixer run into stone by card after, self can produce elastic deformation, thus continue after getting around stone to stir, avoid the infringement that rigid blade brings.When needing to change blade, unload the nut 4 of petiole 2, very convenient.
