[0034] The maintenance assembly includes a convex ring 5 and a material - blocking cylinder 7. An opening is provided on the delivery pipe 1. A material - blocking cylinder 7 is sleeved on the delivery pipe 1. The connection between the delivery pipe 1 and the material - blocking cylinder 7 can be disassembled, and the material - blocking cylinder 7 can cover the opening.

[0035] The conveying assembly further includes a convex plate 16, a transmission shaft 17 and an extension plate 18. A number of convex plates 16 are connected to the second screw 15, a number of transmission shafts 17 are connected to the first screw 12, a number of extension plates 18 are connected to the transmission shafts 17, the extension plates 18 are connected to the convex plates 16. The transmission shaft 17 is prism-shaped, preferably triangular prism-shaped. Spiral-wound plates are provided on the outer walls of both the second screw 15 and the first screw 12. The first screw 12 and the transmission shaft 17 are preferably fixedly connected. The first screw 12 can pass through the opening provided on the conveying pipe 1. The material blocking cylinder 7 and the conveying pipe 1 are connected by bolts. Preferably, the material blocking cylinder 7 is made of a transparent material, and the transparent material can be selected from acrylic or glass. The rotary driving part 2 is a motor, preferably an electric motor. By driving the second screw 15 and the first screw 12 to rotate through the rotary driving part 2, the material can be effectively transmitted. And when maintenance is required, the connection between the material blocking cylinder 7 and the conveying pipe 1 is disassembled, the material blocking cylinder 7 is moved to make room for the opening, and the maintenance personnel can observe the internal structure of the conveying pipe 1 from the outside and perform maintenance. The second screw 15 and the first screw 12 are connected to transmit the material. During maintenance, the connection between the first screw 12 and the second screw 15 can be disassembled, and the first screw 12 can be taken out from the opening, which is convenient for maintenance, convenient for the maintenance personnel to operate and observe the internal situation, and some parts at the transmission part can be replaced, saving the maintenance cost.

[0036] Refer to Figure 1 , wherein the maintenance assembly further includes a branch pipe 3. A branch pipe 3 is communicated with the conveying pipe 1. The branch pipe 3 is located in the relatively middle area between the feed pipe 4 and the rotary driving part 2. Through the arrangement of the branch pipe 3, when other materials need to be added, they can be transmitted through the branch pipe 3, or when cleaning, the cleaning liquid can be transmitted into the conveying pipe 1 through the branch pipe 3, which is beneficial to cleaning the inside of the conveying pipe 1.

[0037] Refer to Figure 1 and 2 , the maintenance assembly further includes a support ring 8 and a limit screw 9. A number of support rings 8 are connected to the conveying pipe 1. The convex ring 5 can move into the support ring 8. The limit screw 9 is connected to the support ring 8 by thread. One end of the limit screw 9 can extend into the support ring 8. Through the arrangement of the support ring 8, the support ring 8 supports the limit screw 9. After moving the material blocking cylinder 7, the convex ring 5 is moved into the support ring 8, and then the limit screw 9 is rotated so that one end of the limit screw 9 restricts the position of the convex ring 5, thereby restricting the position of the material blocking cylinder 7, which is convenient for positioning the material blocking cylinder 7.

[0038] Refer to Figure 1 , the convex ring 5 includes a limit groove 6. A limit groove 6 is provided on the convex ring 5. The limit screw 9 can be inserted into the limit groove 6. Through the arrangement of the limit groove 6, the limit screw 9 and the limit groove 6 cooperate to reduce the rotation of the material blocking cylinder 7 and improve the positioning effect of the material blocking cylinder 7.

[0039] Refer to Figure 5And 6 The conveying assembly further includes a sealing ring 14. A plurality of sealing rings 14 are arranged inside the material retaining cylinder 7. The sealing ring 14 is preferably a rubber ring. The sealing ring 14 is in close contact with the conveying pipe 1. By providing the sealing ring 14, the sealing effect between the material retaining cylinder 7 and the conveying pipe 1 is improved, and the leakage of the internally transported material is reduced.

[0040] Referring to Figure 1 The maintenance assembly further includes a sensor 13. A plurality of sensors 13 are installed on the support ring 8. The sensor 13 is preferably electrically connected to a controller. The controller is a PLC or a computer. The controller is preferably a controller with a display screen and can be displayed on the display screen after the sensor 13 is triggered. The sensor 13 is a proximity sensor 13 or a photoelectric sensor 13. By providing the sensor 13, it is more convenient to determine the positions of the convex ring 5 and the material retaining cylinder 7. After the sensor 13 is triggered, a signal can be transmitted to the controller, enabling the controller to determine whether maintenance is being carried out for other reasonable control.

[0041] Referring to Figure 1 And 2 The maintenance assembly further includes a handwheel 11. The handwheel 11 is installed on the limit screw 9. By providing the handwheel 11, it is convenient to drive the limit screw 9 to rotate.

[0042] Referring to Figure 2 The maintenance assembly further includes a nut 10. The nut 10 is threadedly connected to the limit screw 9. By providing the nut 10, after the position of the limit screw 9 is determined, the nut 10 is tightened. The cooperation between the nut 10 and the limit screw 9 improves the positioning effect of the limit screw 9 and reduces the loosening of the limit screw 9.

[0043] During use, the material to be transported is transported into the conveying pipe 1 through the feed pipe 4, and the rotary drive part 2 drives the second screw 15 and the first screw 12 to rotate to drive the material to be transported. When maintaining the inside of the conveying pipe 1, the connection between the material retaining cylinder 7 and the conveying pipe 1 is disassembled, and then the material retaining cylinder 7 is moved to open the opening position on the conveying pipe 1. The connection between the first screw 12 and the second screw 15 is disassembled, and the first screw 12 is removed.
