[0018] A further beneficial effect is that the second spiral blades provided on the surface of the stirring shaft inside the second mud discharge pipe accelerate the mud discharge by utilizing the rotational force of the second rotary drive member, thereby improving the mud discharge efficiency.

[0019] A further beneficial effect is that the positioning lugs provided on the edge of the slurry plate and the positioning openings provided on the frame allow the slurry plate to be placed directly on the frame when the frame is placed upside down without the need for manual support, which is beneficial to improving welding efficiency and at the same time can improve the horizontal accuracy of the slurry plate after welding.
