The second conveying component 2 includes a second conveying pipe 21 that is communicated with and detachably connected to the first conveying pipe 11. Similarly, a mechanical structure for conveying materials can be provided inside the second conveying pipe 21, or when pneumatic conveying is adopted, there is no need to provide a mechanical structure for conveying materials inside the second conveying pipe 21. The connecting component 3 includes a connecting piece 31, a connecting shaft 32 provided on the connecting piece 31, and a connecting arm 33 connected to the first conveying pipe 11 and the connecting shaft 32. The position of the connecting piece 31 is fixed by connecting to an external bracket.

[0035] According to the above structural design, in the state where the first conveying pipe 11 and the second conveying pipe 21 are disconnected, due to the fixed position of the connecting piece 31, when an appropriate external force is applied to the first conveying pipe 11 by the operator, the first conveying pipe 11 and the connecting arm 33 can be driven to rotate around the connecting shaft 32. When the first conveying pipe 11 rotates along the connecting shaft 32, it will deviate from its original axis position, realizing the separation of the positions of the first conveying pipe 11 and the second conveying pipe 21, facilitating the operator to observe the internal conditions of the first conveying pipe 11 and the second conveying pipe 21, and facilitating the maintenance of the first conveying pipe 11 and the second conveying pipe 21.
