Abstract：To solve the problem of difficult control of the void spacing for reed highstanding barrier, the pore pushing mechanism of reed highstanding barrier bunching device was designed. For the key parts of the proposed mechanism, the design and parameter determination of push arc plate, the calculation of push cam profile by analytical method and the design and calculation of gap push rod were included. A threedimensional model of the void pushing mechanism was established, and the model was introduced into the ADAMS environment. The kinematics simulation analysis of the virtual prototype was carried out, and the motion law of the mechanism driven by the slow pushing cam was investigated. A void distance control pushing rod mechanism was developed for the void control test. The test results show that the average void rate is 50.13%, which verifies the established model. The correctness and rationality of the design can provide a reference for the research and development of automatic reed high vertical sand barrier bundler in the future.
