The utility model discloses a crusher sieve bottom which comprises a base, a bumping mechanism and a sieving mechanism, a spring is welded at the center of the upper surface of the base, a supporting seat is welded at the top end of the spring, a servo motor is fixed in the supporting seat through a bolt, and a fixing disc is welded on the outer surface wall of the supporting seat. A circular sliding rail is arranged on the upper surface of the fixing disc. According to the screening device, the servo motor drives the screening mechanism to rotate, so that materials in the screening mechanism move under the action of centrifugal force, the situation that the materials are blocked is reduced, and through the design of the jolting mechanism, an air cylinder drives a fixing disc to incline left and right through a first rotating base; the fixing disc drives the screening mechanism to incline through the coupler and the auxiliary supporting rod at the same time, so that the jolting mechanism can drive materials i
