Abstract

The invention discloses an oilseed rape combine harvester vertical cutting knife with an airflow recycling device. The oilseed rape combine harvester vertical cutting knife comprises a cutting platform, a draught fan is installed on the cutting platform, connected to a hydraulic motor and a second airflow distributor, the second airflow distributor is connected with a first airflow distributor through a third air pipe, and the first airflow distributor is connected with a main airflow pipe through a first air pipe. According to the oilseed rape combine harvester vertical cutting knife with theairflow recycling device, airflow generated by the draught fan can be blown to scattered rapeseeds, thus the rapeseeds are blown into a seed collecting bin, the scattered rapeseeds can be conveniently collected, waste can be avoided, the cutting efficiency of a harvester can be conveniently guaranteed, the airflow generated by the draught fan can be conveniently distributed, the airflow generatedby the draught fan is applied to different parts, and different functions are generated.

Description

technical field [0001] The invention relates to the technical field related to rapeseed harvesting, in particular to a vertical cutting knife for a rapeseed combine harvester with an airflow recovery device. 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. The natural conditions of different regions are very different, the planting systems are diverse, and the biological characteristics of rapeseed in different regions are quite different, which brings complexity and difficulty to rapeseed harvesting. 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 wi...
