[0002] Safflower is an economic crop that is resistant to poor soil and drought, and has the functions of medicine, food, dye, oil and feed. China, the United States, Pakistan and India have large areas of safflower planting. The flower filament has high practical value, but the flower filament is not easy to collect, the opening time is short, and a large amount of manpower and material resources are needed during picking. The demand for safflower flower filament is increasing year by year, but the existing picking machines cannot meet the picking requirements of safflower, and generally have low harvesting efficiency and low net picking rate. In view of the problem of mechanical picking of safflower, China, India, Italy and other countries have carried out a lot of research, and the existing safflower picking machines can be divided into gas suction type, roller type, combing type and the like according to the working principle, but all have defects such as high energy consumption, high noise and low net picking rate, and the use effect is not very ideal in the actual production process.

The cutting device is slidably connected to the rack, and a commutator is fixedly connected to the rack. The output shaft of the commutator drives the fan to rotate and the cutting device to reciprocate through the power transmission device.

[0005] In the present application, the input shaft of the commutator is connected to the power of the tractor. During the forward driving of the tractor, the fan operates and the cutting device reciprocates, respectively.
