Above-mentioned floated mobile drilling rod mud cleanser; Described special-shaped blob of viscose is close to interlock each other and surrounds a circular hole through compression spring; Be respectively equipped with convexity and the slot that is used for mutual interlock in the both sides of each special-shaped blob of viscose; So that drill pipe coupling through the time can be with the mud scraping on the box cupling, thereby guarantee not leak mud, it is thoroughly clean to scrape slurry.
Above-mentioned floated mobile drilling rod mud cleanser, the nut of said feed screw nut transmission component is fixed on the movable panel, and the leading screw of feed screw nut transmission component runs through annular tube wall and the axial location of the movable panel and the seat that suspends on the seat that suspends.
Above-mentioned floated mobile drilling rod mud cleanser, described inner sliding sleeve, movable panel and compression spring are respectively square, scrape the slurry effect with raising.
Above-mentioned floated mobile drilling rod mud cleanser, the upper surface of cover studs with ball in fixing side, the friction when reducing to pull out of hole between fixing side cover and the housing.
Above-mentioned floated mobile drilling rod mud cleanser is provided with strip-shaped clamp groove in the bilateral symmetry of special-shaped blob of viscose, and corresponding center one end that suspends seat is arranged with card edge on described inner sliding sleeve, and described special-shaped blob of viscose passes through the card of strip-shaped clamp groove and inner sliding sleeve along clamping.
Above-mentioned floated mobile drilling rod mud cleanser, described suspension seat are cylindrical and are made up of base plate and the sleeve pipe that is welded on the base plate outer rim.
Above-mentioned floated mobile drilling rod mud cleanser, described fixing side's cover is six, to guarantee to scrape the slurry effect.
The utility model has the advantages that: owing in fixing side cover, be provided with inner sliding sleeve and special-shaped blob of viscose; Movable panel and compression spring in inner sliding sleeve make special-shaped blob of viscose can regulate its circular hole that surrounds size automatically through compression spring, and special-shaped blob of viscose can be close to the surface of drilling rod and box cupling and can not block box cupling when making trip-out; Therefore can whole drilling rod of scraping and box cupling on mud; Avoid mud to splash on the rig floor and contaminated environment and influence workman's operation, eliminated potential safety hazard, labour intensity is little; Easy installation and removal can not influence the trip-out operation.
