Low-abrasion pipeline conveying mechanism for ship sand pump

The invention discloses a low-abrasion pipeline conveying mechanism for a ship sand pump. The low-abrasion pipeline conveying mechanism comprises a pipe body and a flow guide assembly in the pipe body. A separation assembly is arranged in the pipe body, a transmission assembly is arranged at one end of the separation assembly, the separation assembly and the flow guide assembly form a cavity for fluid movement, the transmission assembly drives the separation assembly to move through flowing fluid, the separation assembly comprises magnetic attraction rings, and material pushing plates are arranged in the two magnetic attraction rings. The material pushing plate reciprocates along the magnetic attraction ring through the transmission assembly and continuously cleans the attracted metal substances, the material pushing plate arranged in the magnetic attraction ring is driven by the transmission assembly to move, so that the material pushing plate continuously cleans the metal particle substances attracted by th
