[0002] The Chinese patent database discloses a patent entitled "A screw conveyor tilt angle adjustment device", application number: CN201120205684.0, application date: 2011.06.17, the patent specification

[0014] paragraph discloses: When the screw conveyor tilt angle adjustment device of the utility model is used, the screw conveyor 4 is placed in the arc-shaped groove body of the adjustment support 1, and the legs 2 are placed on the ground. When the tilt angle of the inclined conveyor 4 needs to be adjusted, the second screw 26 is loosened with a wrench, and then the adjustment support 1 is rotated around the first circular hole on the legs 2, and the second nut 26 moves to the appropriate position in the guide hole 112. When the angle of the screw conveyor 4 is adjusted to the right position, the second screw 26 is tightened to achieve the conveying angle adjustment of the screw conveyor 4.

[0003] The disadvantage is that the angle still needs to be adjusted manually with a wrench, which is labor-intensive and has low work efficiency. Utility Model Content
