During operation, the chain-driven hydraulic motors 3-4 on both sides mainly provide the clamping force for the cotton stalks, so that the cotton stalks can be smoothly pulled out during the forward driving process, and the clamping force is maintained for backward transmission. Figure 4 As shown, the structure of the cutting device 4 is that the saw blade 4-2 is installed on the saw blade hydraulic motor 4-4, and the saw blade hydraulic motor 4-4 is fixed to the U-shaped frame 4-1 by fastening bolts, and the saw blade protective shell 4-3 is fixed to the saw blade hydraulic motor 4-4 to prevent the saw blade 4-2 from flying and injuring people and causing device failure. After the rod is pulled out, the cotton straw continues to be transported backward due to the clamping force of the clamping chain 3-3. During the process, the root straw will be cut and separated by the cutting device 4. The separated root straw falls to the lower impurity removal and conveying device 5 due to gravity, and the power provided by the power hydraulic motor 7-5 is transmitted to the central axis of the impurity removal and conveying device 5 through the transmission device 8. The impurity removal and conveying device 5 will generate certain vibrations during operation, thereby screening out impurities such as soil blocks contained in the root straw, and finally the root straw is recovered to the root straw recovery silo 9 along the impurity removal and conveying device 5.

The middle part of the straw after segmentation is crushed by the crushing roller 7-6 and then piled up at the conveying auger 7-7. The other end of the crushing roller 7-6 is connected to the pulley, and the power provided by the power hydraulic motor 7-5 is transmitted to the conveying auger 7-7 through the transmission device 8. As the conveying auger 7-7 works, the crushed straw is transported to the side of the fan 7-4. The fan 7-4 blows the crushed straw through the air supply duct 7-3 to the recovery bin 7-2, completing the crushing and recovery of the middle part of the straw.
