[0002] The soil powder air separation device is mainly used for fine classification of soil powder. This device separates the different components in the soil powder through wind system and mechanical vibration.

[0003] When air sorting soil powder, operators generally choose electric air sorters to perform air sorting operations on the soil powder, which is used to achieve efficient and accurate separation of soil powder, so as to meet the different needs of soil powder in different fields. Through air sorting, impurities in soil powder, such as stones, brick and tile fragments, etc., can be removed, thereby improving the purity and quality of soil powder. When the electric air sorter is air sorting soil powder, because the soil powder is lighter, the soil powder will be discharged from the air outlet of the air sorter, and the impurities therein will be discharged from the discharge port. Because the electric air sorter is generally set to a larger opening and cannot guide the discharged powder, the air-selected soil powder will be sprayed out in a more dispersed manner, resulting in too large an area of ​​powder accumulation, which brings inconvenience to the later operator's collection operation.

[0004] Therefore, the utility model provides a soil powder air separation device to solve the above problems. Utility Model Content

[0025] During specific use, the electric push rod 17 is started, and the movable end of the electric push rod 17 drives the movable plate 15 to move in the movable groove 14, so that the movable plate 15 will drive the pulley 16 to move downward, so that the pulley 16 contacts the ground, so that the pulley 16 will support the entire air selection device, and the air selection device can be conveniently moved by the pulley 16.

[0026] Preferably, the position of the air outlet 4 is connected to the position of the inner space of the protrusion 6 .
