Material blocking device for radioactive material conveying automatic assembly line

The invention provides a material blocking device for a radioactive material conveying automatic assembly line, and belongs to the field of radioactive material conveying. The device comprises a material blocking sensor and a base bottom plate which are located on the opposite sides of the automatic assembly line respectively, an installation base is arranged on the base bottom plate, the bottom of the installation base is fixedly connected with a sliding base, the sliding base is installed on a first sliding rail in a matched mode, a carrier pushing block is arranged at one end of the installation base, and a first rack is arranged on the side face of the installation base and is in matched meshing transmission with a gear. The gear rotates under the action of the servo motor to drive the mounting seat to move, so that the carrier push block pushes and compresses the carrier to realize material blocking, and a limiting sensor for limiting the first rack is mounted on the base bottom plate.
