[0007] As an improvement, a group of opposite sides of the hollow fixing plate are welded with T-shaped clamping grooves for clamping the buckles.

[0008] As an improvement, the arc-shaped fixing frame comprises a hollow clamping plate fixed to the sidewall of the discharge port of the lifting and conveying assembly through a bolt structure, a hollow buckle plate connected to the hollow fixing plate through buckles, and a plurality of arc-shaped connecting rods welded between the hollow clamping plate and the hollow buckle plate, the corrugated pipe passes through the limiting groove formed by the arc-shaped connecting rods, and the discharge end of the lifting and conveying assembly passes through the cavity of the hollow clamping plate.

[0009] As an improvement, the tea receiving opening and the hollow buckle plate are connected to the buckles through a pin structure.

[0010] As an improvement, the bottom surface of the hollow fixing plate is provided with an anti-skid ring passing through the inner wall of the tea receiving opening.

[0011] As an improvement, an air blowing device is arranged above the discharge end of the lifting and conveying assembly to prevent tea from being blocked.

[0012] As an improvement, the air blowing device comprises an inverted U-shaped fixing frame welded above the discharge end of the lifting and conveying assembly, an air gun fixed to the top end of the inverted U-shaped fixing frame, and an air pressure pump fixed to one side of the inverted U-shaped fixing frame through bolts, and the air outlet of the air gun passes through the internal slot hole of the hollow clamping plate.
