Linear feeder for preventing material blockage of vibration disc

The utility model discloses a linear feeder used for a vibration disc and capable of preventing materials from being stuck, and relates to the technical field of vibration discs. The material vibrating device comprises a material vibrating disc and a linear feeder, the linear feeder comprises at least two stages of linear feeding mechanisms; the ends of every two adjacent linear feeding mechanisms are connected in an end-to-end fit mode. A linear feeding mechanism is connected to a feeding port of the vibration disc in a matched mode. A vibration feeder is assembled at the bottom of each linear feeding mechanism, and a mounting seat is fixedly mounted at the bottom of each vibration feeder; grafting clamps are uniformly arranged on the linear feeding mechanism. Through the effect of designing at least two stages of linear feeding mechanisms, when a gap between two adjacent grafting clamps on the linear feeding mechanism close to a feeding port begins to be lower than a normal value, starting and stopping of t
