Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

The embodiment is as follows:

as shown in fig. 1-3, novel extruder screw rod, including screw pushing body 1, the inboard cover of screw pushing body 1 is equipped with drive shaft 2, the front end outside cover of drive shaft 2 is equipped with conveying rod 3, be equipped with the separation base 8 that cup joints in the drive shaft 2 outside between conveying rod 3 and the screw pushing body 1, two silos 4 have been seted up to the outside spiral of conveying rod 3, two silos 4 are parallel distribution in the outside of conveying rod 3, the degree of depth of one of them silo 4 becomes dark from the front to the back gradually, the degree of depth of another silo 4 becomes shallow from the front to the back gradually.
