8. The raw material premixing device for the production of the electric power protection plastic pipe as claimed in claim 4, wherein: the transmission device (23) comprises a fifth transmission wheel (231), the front surface of the fifth transmission wheel (231) is in transmission connection with one end of the back surface of the connecting shaft (15), a third transmission belt (232) is arranged on the outer surface of the fifth transmission wheel (231), the fifth transmission wheel (231) is in transmission connection with a sixth transmission wheel (233) through the third transmission belt (232), and the front surface of the sixth transmission wheel (233) is in transmission connection with one end of the back surface of the rotating device (24).

9. The raw material premixing device for the production of the electric power protection plastic pipe as claimed in claim 8, wherein: the rotating device (24) comprises a second rotating shaft (242), one end of the back face of the second rotating shaft (242) is in transmission connection with the front face of the sixth driving wheel (233), a second bearing (241) is sleeved on the outer surface of the second rotating shaft (242), the second rotating shaft (242) is connected to the back face of the sealing cover (30) in a clamped mode, and one end of the front face of the second rotating shaft (242) penetrates through the sealing cover (30) to be fixedly connected with the back face of the third gear (25).

10. The use method of the raw material premixing device for the production of the power protection plastic pipe is characterized by comprising the following use steps of:

s1, when the premixing device is used, plastic pipe raw materials to be processed are poured into a processing shell (29) through an external feeding mechanism, a driving device (1), a fan (38) and a heating device (36) are started, the grinding rollers (27) are driven to rotate by a first driving wheel (2), a second driving wheel (14) and a third gear (25) when the driving device (1) runs, the third gear (25) is meshed with a fourth gear (26), so that when the grinding rollers (27) on one side rotate, the grinding rollers (27) on the other side rotate in the opposite direction of the third gear (25) along with the driving of the fourth gear (26), and when the grinding rollers (27) on the two sides rotate in the opposite direction, the plastic pipe raw materials falling into the processing shell (29) are extruded by the grinding rollers (27) on the two sides;

s2, because the plastic tube raw material crushed by two grinding rollers (27) still has a large block with uneven volume, when the large plastic tube raw material with uneven volume enters the conveying pipeline (19), as the second driving wheel (14) drives the connecting shaft (15) to rotate, the plastic pipe raw material entering the conveying pipeline (19) can move backwards under the driving of the helical blades (18), and the plastic pipe raw materials with uniform volume can fall into the stirring box (12) under the action of gravity in the moving process, the plastic pipe raw materials with uneven volume can enter the communicating hole (22) along with the driving of the helical blade (18), because the fan (38) continuously discharges air upwards through the exhaust pipe (20), the plastic pipe raw material with uneven volume enters the exhaust pipe (20), then enters the exhaust shell (31) along with the rising gas and falls into the processing shell (29) again;

s3, when the driving device (1) runs, the driving device (1) can drive the first driving wheel (2) to rotate, because the first driving wheel (2) rotates in the process, the first gear (5) can drive the second gear (6) to rotate, the first driving wheel (2) can drive the second driving wheel (14) to rotate through the second driving belt (13), and the second driving wheel (14) can drive the driving device (23) to rotate through the connecting shaft (15) when rotating.
