Abstract

The invention discloses an oilseed rape harvesting header vertical cutting knife splashing grain air-aspiration type recycling device. The device comprises a header frame. A pneumatic recycling deviceis arranged on the header frame. A feeding packing auger is connected to the header frame. A dividing reel is arranged on the header frame, a vertical cutter is installed on the header frame, and transverse cutters are installed among the header frame. According to the oilseed rape harvesting header vertical cutting knife splashing grain air-aspiration type recycling device, splashed oilseed rapegrains caused by cutting of the vertical cutter can be collected, the negative pressure airflow can change the motion trajectory of the splashed grains, the splashed grains can be better collected into a grain falling collecting bin, oilseed grains in the grain falling collecting bin are recycled through negative pressure airflow, and oilseed rape harvesting losses caused by the vertical cutter are reduced.

Description

technical field [0001] The invention relates to the related technical field of rapeseed harvesting, in particular to an air suction recovery device for rapeseed harvesting platform vertical cutting knife splashing grains. Background technique [0002] my country's rapeseed planting area and output rank among the top in the world, with an annual planting area of ​​about 100 million mu. Because rapeseed plants are tall, branched, densely intersected and intertwined with each other, most rapeseed combine harvesters are equipped with vertical cutting knives on the basis of the rice and wheat harvester header to cut off the rape that is involved in the uncut area and the cut area. However, when the vertical cutting knife cuts the rape stalk, it will cut off the rape pod at the same time, causing splash loss of seeds. Contents of the invention [0003] The purpose of the present invention is to provide a kind of air absorption and recovery device for the vertical cutting knife ...
