The utility model discloses a double dynamical mining jigging machine of improved generation, including unable adjustment base, its characterized in that, unable adjustment base top bilateral symmetry fixedly connected with fixed bolster, the right side the upper right cavity of fixed bolster upper left side fixedly connected with, the upper left cavity of upper right cavity left side fixedly connected with, upper left cavity is connected with the left side fixed bolster, and upper left cavity downside is provided with the left mantle body, and upper right cavity downside is provided with right mantle and personally experiences sth. Part of the body, between the left side mantle body and the upper left cavity, all be connected with the diaphragm between the right mantle body and the upper right cavity. Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, for traditional single action power jigging machine, this device adopts double dynamically for production level simultaneously and vertical dual vibration when carrying out the jigging screening, the efficiency that can promote the jigging to screen on the one hand, on the other hand can promote the accuracy nature of screening.
