SCHOLIN LOOSE MATERIAL PNEUMATIC SEPARATOR Russian patent published in 2018 - IPC B07B4/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the agricultural machine building, in particular to the equipment for the small mass of bulk material of the weed or other undesirable impurity cleaning by the airflow, and can be used, for example, for the different crops seeds sorting for breeding purposes or for manual labor mechanizing when removing weeds in the harvested forest berries. Bulk material pneumatic separator includes vertically oriented pneumatic separating channel with three windows, the upper, lower and middle transverse window with union for connection to the fan duct, initial material feeder, through the upper window communicated with the pneumatic separating channel and hermetically attached to the bottom window receiving hopper for the cleaned material collection. Separator elements are made from the fragments of different capacity thermoplastic blown bottles. Pneumatic separating channel is made in the form of two bottles hermetically connected to the upper and lower windows, by the bottles necks and by the middle transverse window to the union, receiving hopper for the cleaned material collection is made in the form of forming the separator body hermetically coupled counter-oriented one bottle lower cylindrical part and the second identical bottle with separated bottom upper part. Second bottle neck is hermetically connected to the pneumatic separating channel lower window. Initial material feeder is made in the form of funnel from the plastic bottle with neck upper part. Middle transverse window union is brought beyond the body outer side, and connected to the union fan is made the exhausting one and is equipped with the filter. Cleaned material receiving hopper is made detachable and is equipped with the communicating with atmosphere window.

EFFECT: device design simplification and reducing its dimensions.
