The invention discloses a thin bamboo strip automatic sorting machine capable of cleaning surfaces. The machine comprises a base plate; vertical plates are fixedly connected to the left and right sides of the top of the base plate; long rods are fixedly connected to the bottoms of the inner sides of the two vertical plates; lifting mechanisms are mounted on the outer walls of the long rods; the lifting mechanisms comprise first sleeve plates, vertical rods, second sleeve plates, bent plates and rubber pads; and the inner walls of the first sleeve plates are slidingly clamped with the outer walls of the long rods. Through cooperation of the long rods, the lifting mechanisms and grinding wheels, the problem of incapability of removing burrs is solved, the harm to workers is prevented, the normal operation machining is guaranteed, the working efficiency is improved, and the working difficulty is reduced; through cooperation of a sorting mechanism and a control mechanism, the manual pullaway trouble is saved, the labor consumption is prevented, the cost is reduced, and the working time is shortened; and through cooperation of curved plates, second springs and straight plates, the use is simple and convenient, the time is saved, the practicability is improved, the functions are comprehensive, and the popularization is convenient.
