Wherein, the upper hydraulic stem 9, lower hydraulic stem 12 telescopic end elongate or shorten respectively, to drive upper agitating shaft
10, lower agitating shaft 13 moves up and down, to adjust stirring region.
The transverse direction agitating plate 11 installs scraping article 15 in bottom along its length, and the vertical agitating plate 142 is along its length
Degree direction is also equipped with scraping article in the one side close to 1 inner wall of shell, and the scraping article 15 is strip triangle column, scraping article 15
It is wherein attached on one side on the panel of lateral agitating plate 141, vertical agitating plate 142；It is columnar for triangle inside the scraping article 15
Stainless steel inner core and wrap up rubber layer outside it；The face for being wherein attached at lateral agitating plate, vertical agitating plate on one side of scraping article
On plate；It is the columnar stainless steel inner core of triangle inside the scraping article and wraps up rubber layer outside it.
The workflow of this blender is as follows, and evacuator 8 extracts the air in shell 1 by vacuum lead 7, makes it
Inside is negative pressure vacuum environment, can make so more fluffy between material and material, is more conducively stirred；First material from into
Material mouth enters in shell 1, falls in shell, and the vertical stirring blade 142 of agitating plate 14 and the bottom, lateral stirring blade 141 are all
Material will further be crushed；Lateral stirring blade 141, vertical stirring blade 142 not only can any to housing bottom one
A corner is stirred, and stirring is more uniformly abundant, and can be glued viscous powder material to 1 inner wall of shell and be struck off.
And for the columnar stainless steel inner core of triangle and rubber layer outside it is wrapped up inside scraping article 15, it again will not shell while striking off
Interior wall construction causes to damage；When the material with stirring is more, starting motor drives upper hydraulic stem 9 to rotate, to stir on driving
The rotation of bar 11 is mixed to be stirred；But also can be extended by controlling the telescopic end of upper hydraulic stem 9, it moves downward, so that
Upper stirring rod 11 moves downward, and is stirred to material, carries out while stirring here with upper and lower stirring rod, stirs to improve
Range is mixed, when material is few, it is only necessary to which the stirring rod of lower layer stirs.
