It can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Its working principle is: when the screw shaft rotates, due to the gravity of the material and the friction between the material and the trough wall, the material can only move forward along the bottom of the conveyor trough under the push of the blades, just like a nut that cannot rotate moves in translation along the rotating screw.

[0030] In this embodiment, the screw conveyor is prevented from rotating on the surface of the deep groove ball bearing 322. As the screw conveyor works, the screw conveyor shaft also rotates, driving the deep groove ball bearing 322 to rotate together. According to the difference between the shafts at both ends of the screw conveyor, the distance between the moving blocks 311 is adjusted, so that the distance between the deep groove ball bearings 322 changes, thereby changing the concentricity of the shaft of the screw conveyor. Embodiment 2

[0031] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 : A driving component 2 is arranged inside the fixed platform 1 for driving the control and adjustment component 3.

[0036] When the screw conveyor is in use, the screw conveyor is prevented from being on the surface of the deep groove ball bearing 322. As the screw conveyor works, the screw conveyor shaft also rotates, driving the deep groove ball bearing 322 to rotate together. According to the difference between the shafts at both ends of the screw conveyor, the distance between the moving blocks 311 is adjusted to change the distance between the deep groove ball bearings 322, thereby changing the concentricity of the shaft of the screw conveyor. The connecting rod 221 is driven to rotate by the driving motor 21 to rotate the rotating shaft 222.
