[0039] The working principle of the above embodiment is:

[0040] (1) The drilling fluid delivery pipeline is connected to the feed pipe 17, and the cleaning fluid delivery pipeline is connected to the liquid delivery pipe 18. The drilling fluid flows along the feed pipe 17 into the space between the tower scraper frame 5 and the filter screen 7. The motor 19 is started to rotate the tower scraper frame 5 at high speed. After centrifugal action, the mud passes through the filter screen 7 and enters the conical bin 4. The rock chips are separated and fall down.

When the hydraulic push rod 111 is extended and retracted, it can move horizontally with the rack 112. The rack 112 transmits power to the fan gear 114. The fan gear 114 drives the connecting rod 113 to swing back and forth with the cleaning assembly 10. At the same time, the controller turns on the motor 3 105 to rotate the reciprocating screw 106. The reciprocating screw 106 drives the telescopic rod 102 to move up and down with the scraper 103, thereby cleaning the rock debris blocked at the discharge hole 8;

[0042] (3) The cleaning liquid recovery pipe is connected to the bottom end of the liquid collecting bucket 13. The cleaning liquid flowing out of the liquid outlet can enter the liquid collecting bucket 13 from the liquid outlet groove 14, and then be transported to the cleaning liquid processing equipment by the liquid collecting bucket 13. After treatment, the cleaning liquid can be reused.
