The invention provides a material lifting device. The material lifting device comprises a power unit, a lifting mechanism, an outer sleeve, an inner sleeve and a material conveying mechanism, wherein the power output end of the power unit is connected with the power inlet end of the lifting mechanism; the inner sleeve is sleeved with the outer sleeve; the material conveying mechanism is fixedly connected with the outer sleeve; the lifting mechanism is arranged inside the inner sleeve, and is used for driving the outer sleeve to do axial movement. Since lots of impurities, such as oil contaminations or iron filings, can be generated when the lifting mechanism is in operation, the impurities can be effectively prevented from polluting the environment of a clean room by arranging the lifting mechanism inside the inner sleeve.
