The invention discloses a smashing assembly for a soybean milk machine and the soybean milk machine with the smashing assembly. The smashing assembly comprises a smashing knife which comprises a knife body and a shearing wing arranged at the edge of the knife body, and a smashing hood, wherein the smashing hood comprises a hood body and a plurality of hood legs which are arranged at the edge of the hood body and are spaced along the circumferential direction; the smashing knife can coaxially pivot relative to the smashing hood so as to form a shearing region between a shearing blade and the shearing wing; the surface on one circumferential side of at least one hood leg is configured into a stop part for stopping a material colliding towards the hood leg and forcing the material to enter the shearing region; an included angle beta between the stop part and a tangent line of the stop part is 3 to 90 degrees; on a horizontal projection of the smashing hood, a tangent line made from the end point of the outermost end of the stop part to a rotating trace circle of the smashing knife is the tangent line of the stop part. According to the smashing assembly, as the stop part is arranged on the smashing hood, and the included angle beta between the stop part and the tangent line of the stop part is 3 to 90 degrees, the smashing effect of the soybean milk machine can be enhanced.
