Anti-blocking material conveying pipeline

The utility model discloses an anti-clogging material conveying pipeline which comprises a pipeline body, a contact plate, an arc plate, a pull rod and a transmission rod. The arc plate is movably installed at the top of the pipeline body, one end of the pull rod is fixedly welded to the bottom of the outer wall of the arc plate, and the other end of the pull rod is movably connected with the transmission rod. One end of the transmission rod away from the pull rod is fixedly welded to the lower surface of the contact plate; when the contact plate is pressed down by an object, the arc plate ispulled outwards by a certain distance through the transmission rod, so that the inner diameter of the section, located on the arc plate, of the pipeline body is increased to release materials in the pipeline. The collecting hopper is fixedly mounted at the top of the pipeline main body and is used for collecting materials into the pipeline main body. The contact plate is pressed down when materials fall down, then the con
