In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a novel rotatory clear stifled device of pipeline, includes barrel, rotary speed reducer and lower barrel, go up barrel and lower barrel and be connected as an organic wholely by the support frame, rotary speed reducer is located between barrel and the lower barrel, go up barrel, rotary speed reducer and the concentric same diameter arrangement of lower barrel, rotary speed reducer is equipped with slewing bearing, and has set firmly the initiative arm on rotary speed reducer's the inner wall, is equipped with clear stifled sword subassembly on the initiative arm.

Further, the height of the rotary speed reducer is 200-300mm, the blockage-removing knife assembly comprises a plurality of blockage-removing knife rest, and the length of the blockage-removing knife rest is 1-2 meters.

Turbine external teeth are arranged on the outer side of the slewing bearing of the slewing reducer.

Compared with the prior art, the utility model has the beneficial effects that: the multi-section blockage removing knife is adopted, so that the flow section of the pipeline is effectively increased, and the blockage source is reduced; the number and the angle of the block-removing tool rest can be adjusted at will, and the block-removing tool rest is designed according to the length of the pipeline; the integral unidirectional rotation is adopted, so that the damage to equipment parts caused by stress concentration due to the reciprocating rotation is avoided, the reliability of the equipment is improved, and the service life of the equipment is prolonged; the height of the rotary speed reducer is 200-300mm, the height is shorter, downward extrusion flushing is formed on the rotary speed reducer, and the adhesion of materials on the inner wall of the rotary speed reducer is avoided; the multi-group block-cleaning tool rest combination can be realized, the block-cleaning length is increased, and the problem that a single block-cleaning tool is bent due to too long because of enlarging the block-cleaning length originally is avoided. The length of the single blockage-removing tool rest is between 1 meter and 2 meters, and the blockage-removing tool body is connected with the main shaft through one or more cantilevers, so that bending caused by larger resistance is avoided.
