As shown in fig. 4-8, the soil pick-up head 7 includes an inner blade mechanism and an outer blade mechanism.

The peripheral blade mechanism includes a blade holder 71, a blade motor 72, and a peripheral blade 73. The blade holder 71 includes an outer sleeve 711 and an inner sleeve 712. The blade holder 71 is mounted outside the dirt suction tube 3 by fasteners. The outer and inner sleeves 711, 712 are vertically mounted. The top ends of the outer sleeve 711 and the inner sleeve 712 are sealed. The outer top end of the outer sleeve 711 is mounted on the blade support 71, and the outer top end of the inner sleeve 712 is sleeved into the outer sleeve 711 from the bottom end opening of the outer sleeve 711. A return spring 7112 is installed between the inner top end of the outer sleeve 711 and the outer top end of the inner sleeve 712, that is, one end of the return spring 7112 is connected with the inner top end of the outer sleeve 711, and the other end is connected with the outer top end of the inner sleeve 712.

S3: after the motor rotates for a period of time, the sewage pump 4 is started on the operating platform (17), and then the valve 5 is opened. During this time, the outer blade 73 touches a hard solid such as stone or metal, the inner sleeve 712 drives the inner gear 7122 to rotate, the inner sleeve 712 moves into the outer sleeve 711, and the rotating outer blade 73 moves away from the hard solid, thereby protecting the outer blade. After the danger is eliminated, the return spring 7112 returns, the inner gear 7122 rotates, the inner sleeve 712 returns to the original position, and the outer blade 73 continues to operate.

S4: sludge separation is monitored by the observation chamber 12. After the filter screen 15 in the separation chamber 1 is filled with sludge, the valve 5 is closed, the sewage pump 4 is closed, and finally the blade motor 72 and the inner pipe blade motor 74 in the sewage suction head 7 are closed.
