A buffer type material vibration device, comprising a frame (7), a vibrating material containing part (9) hinged to the upper part of the frame (7) through a hinge shaft (90), and a A vibration-driven slider (8) that moves left and right on the roller track (71) at the bottom of the frame (7), wherein the vibration-driven slider (8) includes a middle main body (83) and symmetrically arranged Two slope parts (81, 82), the two slope parts (81, 82) are respectively provided with mutually symmetrical slope chute (811, 821), in order to respectively carry the left support slider (812) and the right support The slider (822) slides, the left support slider (812) and the right support slider (822) are symmetrically arranged on the left and right ends of the lower side of the vibrating material containing part (9) respectively. The protrusions (91, 92) are hinged.
