The invention discloses an egg knocking machine which comprises a base; the base is provided with an egg conveying channel; an egg blocking part is arranged outside an exit of the egg conveying channel; a bearing part is rotatablely connected with the base, and the edge of the bearing part is corresponding to a position at the exit; the egg blocking part is used for blocking the outside upper partof an egg positioned at the exit; the bearing part is used for bearing the bottom of the egg positioned at the exit, so that the egg partially exposes at the exit; the bearing part is provided with anotch; an oscillating arm is arranged at the notch; the inner end of the oscillating arm is hinged to the bearing part; an egg support is arranged at the outer end of the oscillating arm; the base isfixedly provided with a guide ring; the oscillating arm leans on the top side of the guiding ring in a sliding manner; the bearing part is fixedly provided with a shifting part; the shifting part ispositioned above the oscillating arm; the base is provided with an egg knocking elastic sheet; the egg knocking elastic sheet is positioned between a rotation plane of the shifting part and a rotationplane of the egg support; and the egg knocking elastic sheet breaks the egg borne by the egg support when the egg support passes through the egg knocking elastic sheet. The feeding link and the egg knocking link not only are automatically carried out, but also are synergistic and coherent, so that the efficiency is higher.
