Referring to fig. 1-5, the present invention provides a technical solution: a coal powder bin blanking pipe of a novel dry-process cement pit coal grinding system not prone to being blocked and damaged comprises a pipeline 1, a motor 2 is fixedly installed on the outer side of the pipeline 1, a rotating shaft 7 is connected to the inner wall of the pipeline 1 in a rotating mode, an output shaft of the motor 2 extends into the pipeline 1 and is fixedly connected with the rotating shaft 7, a roller 4 is fixedly connected to the outer side of the rotating shaft 7, when the inner portion of the pipeline 1 is blocked, the inner portion of the pipeline 1 is convenient to clean, two fixing blocks 6 are fixedly connected to the inner wall of the pipeline 1, one sides, away from the inner wall of the pipeline 1, of the fixing blocks 6 are respectively and rotatably connected with a second baffle 13, second sliding grooves 19 are respectively formed in the bottoms of the second baffle 13, third sliding grooves 20 are respectively formed in the two sides of the second sliding grooves 19, second sliding rods 18 are respectively and slidably connected to the inner portions of the third sliding grooves 20, two first sliding grooves 10 are respectively and, the outside of first slide bar 9 and the equal fixedly connected with stopper 12 in inside that is located first spout 10, stopper 12 all with first spout 10 sliding connection, be convenient for extrude return spring 11 through stopper 12, the outside of first slide bar 9 and the inside that is located first spout 10 all overlap return spring 11, the one end of first slide bar 9 extends to the inside of pipeline 1 and rotates with second slide bar 18 and be connected, be convenient for make second baffle 13 cushion the better return after the coal charge through return spring 11, pipeline 1 includes first wearing layer 14, flame retardant coating 15, heat-conducting layer 16 and second wearing layer 17, the bottom and the flame retardant coating 15 fixed connection of first wearing layer 14, the bottom and the heat-conducting layer 16 fixed connection of flame retardant coating 15, the bottom and the second wearing layer 17 fixed connection of heat-conducting layer 16.

Furthermore, a speed reducer 3 is fixedly mounted on the outer side of an output shaft of the motor 2, so that the motor 2 can be stopped better.

Furthermore, the bent part inside the pipeline 1 is fixedly connected with a first baffle 8, so that the bent part of the pipeline 1 can be better protected.

Furthermore, one end of the first sliding rod 9, which is far away from the second sliding rod 18, is fixedly connected with a handle 5, so that the first sliding rod can be better cleaned when being blocked above the second baffle 13.

Furthermore, the first wear-resistant layer 14, the second wear-resistant layer 17, the first baffle 8, the second baffle 13, the rotating shaft 7, the roller 4 and the fixing block 6 are all made of high-chromium cast iron, so that the wear-resistant, high-temperature-resistant and corrosion-resistant properties are good, and the service life of the equipment is prolonged.
