[0006] As a preferred technical solution of the utility model, the negative pressure fan provides suction to enable the safflower filaments to pass through the net knife smoothly and remain upright.

[0007] As an optimal technical solution of the utility model, the brushless DC motor drives the driving gear to rotate, the driving gear rotation drives the driven gear ring meshing with the outside to rotate, the driven gear ring rotation drives the mesh knife to rotate, and the mesh knife rotates and cuts the safflower filaments fed to the end effector.

[0008] As a preferred technical solution of the utility model, the filament feeding device at the lower end of the sleeve has a truncated cone-shaped internal structure, which can maintain the stability of the safflower plant during the harvesting process, thereby improving the filament collection rate.

[0009] Compared with the prior art, the utility model provides an air suction net knife type safflower harvesting end effector, which has the following beneficial effects: the internal structure of the end effector is relatively simple, which can reduce the volume of the end effector to a certain extent, and realize refined harvesting operations. At the same time, the negative pressure fan provides wind force to make the safflower filaments fed into the end effector stand upright, which is convenient for the rotary cutting of the net knife. The end effector can reduce the labor intensity, improve the harvesting efficiency, and reduce the cost of safflower harvesting. BRIEF DESCRIPTION OF THE DRAWINGS
