Eccentric jet device

The utility model provides an eccentric jet device. The device comprises a main pipeline and an auxiliary pipeline, an auxiliary pipeline is fixedly welded to the right end of the annular side face ofthe main pipeline. Eccentric jet pipelines are connected to the front upper part and the rear upper part of the auxiliary pipeline; the left portion of the eccentric jet pipeline is fixed to the front end and the rear end of the main pipeline through clamps. A conveying screw rod is arranged in the eccentric jet pipeline; the upper end of the conveying screw rod is rotationally connected with theinner top of the eccentric jet pipeline through a bearing; the lower right portion of the main pipeline communicates with the lower left portion of the auxiliary pipeline. Compared with the prior art, the eccentric jet pipeline has the advantages that the eccentric jet pipeline is fixed to the outer side of the main pipeline and communicated with the auxiliary pipeline, the purpose of eccentric jet is achieved, the eccent
