[0025] like Figure 5 As shown, it also includes a collecting frame 14 and a discharge pipe 15. The collecting frame 14 is connected to the upper left portion of the rear side of the mounting frame 1, and the discharge pipe 15 is connected to the lower portion of the rear side of the collecting frame 14.

[0026] like Figure 6 and Figure 7As shown, it also includes a connecting block 16, a guide rod 17, a sealing ring 18, an elastic member 19 and a push block 20. The left and right sides of the rear of the electric push rod 5 are connected to the connecting blocks 16, the rear sides of the connecting blocks 16 are connected to the guide rods 17, the two guide rods 17 are slidably connected to the sealing ring 18, the guide rods 17 are sleeved with elastic members 19, the two ends of the elastic member 19 are respectively connected to the connecting block 16 and the sealing ring 18, the elastic member 19 is a spring, and the rear side of the nozzle 6 is connected to the push block 20.

[0030] Initially, the push block 20 pushes the sealing ring 18, and the elastic member 19 is in a compressed state. The staff puts the oil pipe on the two loading plates 2, and the oil pipe rolls to the left on the loading plate 2. Then the output shaft of the motor 8 is controlled to rotate one circle, driving the first connecting rod 9 to rotate one circle. The output shaft of the motor 8 drives the rotating shaft 10 to rotate one circle through the pulley group, and the rotating shaft 10 drives the second connecting rod 11 to rotate one circle. The first connecting rod 9 and the second connecting rod 11 drive the feeding plate 12 to rotate up and down. During the upward rotation process of the feeding plate 12, the oil pipe on the loading plate 2 can enter the semicircular groove 13, and then the material is fed. The plate 12 will rotate downward, and the feeding plate 12 will feed the oil pipe into the dividing groove 3. At this time, the oil pipe is located at the rear side of the nozzle 6. The staff will connect the hard pipe 7 to the preservative, and the preservative will flow into the nozzle 6 through the hard pipe 7, and then the preservative will be sprayed out through the nozzle 6, and the telescopic rod of the electric push rod 5 will be controlled to extend, so as to drive the nozzle 6 to move backward, and the nozzle 6 will enter the oil pipe and spray the preservative into the oil pipe to perform anti-corrosion treatment on the inner wall of the oil pipe. The backward movement of the nozzle 6 can also make the push block 20 move backward, and the push block 20 and the blocking ring 18 will be out of contact. Under the action of the elastic member 19, the blocking ring 18 moves backward. Move and contact with the front end of the oil pipe, the blocking ring 18 blocks the front end of the oil pipe to prevent the preservative from flowing out from the front end of the oil pipe. The preservative will flow out from the rear end of the oil pipe and flow into the collecting frame 14 to reduce the waste of the preservative. Open the discharge pipe 15, and the preservative in the collecting frame 14 is discharged through the discharge pipe 15, which is convenient for recycling. After the spraying is completed, the telescopic rod of the electric push rod 5 is controlled to shorten, driving the spray head 6 and the push block 20 to move forward. The push block 20 will push the blocking ring 18 to move forward, and the blocking ring 18 is out of contact with the front end of the oil pipe. The elastic member 19 is compressed, and the output of the motor 8 is controlled again. The shaft rotates one circle to continue transporting the oil pipe, sending the painted oil pipe to the front side of the fan 21, and sending the unpainted oil pipe to the rear side of the nozzle 6, automatically loading and unloading, which can improve work efficiency and safety. The fan 21 can air-dry the preservative in the painted oil pipe to shorten the drying time of the preservative. When the feeding plate 12 transports the oil pipe again, the air-dried oil pipe will be sent to the discharge plate 24. The air-dried oil pipe will roll to the left along the discharge plate 24 for subsequent collection. Maintenance tools can be stored in the storage box 22 for easy access.
