[0061] It should be noted that, the greater the gravity received by the pressure plate 411, the higher the height of the linkage block 324 rises, thereby causing it to be limited in a higher limiting hole 3131, thereby accelerating the rotating speed of the plurality of second stirring pieces 321.

[0062] In summary, according to the stacked spiral sludge dewatering machine, on the one hand, through the cooperation between the pressure device 41, the transmission device 43 and the stirring device 3, the rising height of the linkage block 324 is changed by the gravity received by the pressure plate 411, thereby automatically adjusting the rotating speed of the plurality of second stirring pieces 321, on the other hand, through the cooperation of the limiting device 42 and the pressure device 41, the third plate 4161 is limited by the clamping plate 424, thereby avoiding the linkage block 324 between the two driven gears 314, thereby avoiding the situation that the second stirring piece 321 stops rotating.
