收割机上的清选筛片
摘要：
本发明公开了一种收割机上的清选筛片。本发明的目的是提供一种即适合收割多种作物的收割机上的清选筛片。本发明技术方案是这样完成的，收割机上的清选筛片，它包括有清选筛片，清选筛片上的筛孔为圆孔。圆孔的直径在20-22mm之间。圆孔的直径在0.3-0.5mm之间。本发明的技术效果是：因将收割机上的清选筛孔改为圆孔，圆孔直径控制在20-22mm之间适合用小麦和玉米收割使用，圆孔直径控制在0.3-0.5mm之间，能够满足收割油菜，能够保证收割机在使用上做到一机两用甚至多用。
摘要（英）：

The present invention discloses a cleaning sieve sheet on a harvester, which aims to provide a cleaning sieve sheet on a harvester which is suitable for harvesting various crops. The present invention is characterized in that the cleaning sieve sheet on a harvester comprises the cleaning sieve sheet, and sieve holes on the cleaning sieve sheet are round holes. The diameter of the round holes is between 20 mm to 22mm. the diameter of the round holes is between 0.3mm to 0.5 mm. because the sieve holes on the harvester are changed into the round holes, when the diameter of the round holes is controlled between 20 mm to 22mm, the cleaning sieve sheet on a harvester is suitable for harvesting wheat and corns; when the diameter is controlled between 0.3 mm to 0.5 mm, the cleaning sieve sheet on a harvester can satisfy to harvest rapes. Thus, one harvester can have two uses even more uses.
