摘要：A grain cleaning device is provided which separates foreign material from grain by aspiration. The aspiration force is developed by a fan which is attached to the grain cleaning device. The device includes a housing, a grain inlet in said housing, a louvered grain slide located within said housing, an opening within the housing which is compatible with the fan, air intake holes within the housing and adjustable covers for said air intake holes. The grain enters the grain cleaning device through the grain inlet and travels down the louvered grain slide. The fan which is located above the louvered grain slide acts as an aspirator and removes the foreign material from the grain which has a density less than the density of the grain. The foreign materials are drawn up through the fan and out an exhaust vent. The housing includes a grain slide housing and a chimney, the chimney being attached to the top of the grain slide housing. The grain slide and grain inlet are located in the grain slide housing and the fan is attached to the chimney. The grain slide extends from below the grain inlet at an angle to the bottom of the grain slide housing. The grain after being cleaned falls out of bottom of the grain slide housing into a pit, grain elevator skirt, etc.
