The utility model relates to a dosing system is stored to buffering that is applicable to viscidity material belongs to feed equipment technical field this feed system puts into the buffer memory storehouse and scrapes the material in order to overcome the dead angle, and the plan view is the kidney type, and half round platform shape that downward one-tenth was falling is designed into at both ends simultaneously at buffer memory storehouse wall mounting air bubble and solenoid valve, when the coal slime is glued the wall or is expanded the storehouse, open the air bubble through control solenoid valve, the air bubble blast air shakes to shake the coal slime on the adhesion bulkhead and falls to subsiding the feeding adjustable screw in next stage equipment was carried the coal slime to the feeding adjustable screw, feeding adjustable screw and next stage equipment junction were equipped with the expansion joint, and the support is connected to add with the buffer memory storehouse and is equipped with damping spring, like this can be the vibrations elimination of playing the air bubble production to guarantee the normal operating of next stage equipment, also guarantee the homogeneity of drying system feed, effectively weaken the material storehouse when unloading the material to the impact of back level equipment, the stability of reinforcing back level equipment feed
