A fixing rod 5-4 is also provided on the outer side of the drive shaft 5-6. The fixing rod 5-4 is provided with teeth 5-5, which are arranged in a comb-like shape. The surface of the wedge-shaped cone head 5-1 is provided with spiral blades 5-3, which are discontinuous and plate-like.

[0092] In actual use: A shaft bottom shell 3 is provided below the cotton picking and conveying hinge. The surface of the shaft bottom shell 3 is provided with impurity discharge holes 2. The picked cotton first undergoes a preliminary separation of cotton and cotton husk. Then, the preliminarily separated impurity-containing cotton enters the cotton picking and conveying hinge from one end of the wedge-shaped cone 5-1. Under the action of the spiral blades 5-3 on the surface of the wedge-shaped cone 5-1, the cotton and cotton husk are squeezed and conveyed to the area where the fixed rod 5-4 is located. Under the action of the wedge-shaped cone 5-1, the cotton and cotton husk can be further separated during the conveying process, so that the impurity-containing cotton entering the area of ​​the fixed rod is separated from the cotton husk. There are multiple sets of fixed rods 5-4. The fixed rods 5-4 form a ring and form a hollow column. The impurity-containing cotton conveyed here is stirred by the fixed rods 5-4 and the prying teeth 5-5 to separate the cotton and impurities such as cotton husk. The cotton is collected, and the impurities such as cotton husk are discharged from below.

[0093] Example 4: Reference Figure 4The diagram below is a structural schematic of Embodiment 4 of this utility model. This embodiment discloses a cotton picking and conveying hinge. Compared with Embodiment 3, the difference in this embodiment is that the surface of the wedge-shaped cone 5-1 is provided with spiral blades 5-3, and the spiral blades are in the form of continuous sheets.

The scraper 7-1 end of the conveying mechanism 7 and the wedge-shaped cone 5-1 end of the cotton hull removal mechanism are located on the same side. The impure cotton is conveyed to the scraper 7-1 by the auger blades. The impure cotton is fed into the wedge-shaped cone 5-1 by the scraper 7-1. The cleaning operation is performed by the rotation of the wedge-shaped cone 5-1.

[0096] In actual use: After being brushed by the carding roller 8, the cotton and cotton husks are brushed into the conveying mechanism 7, and then collected by the conveying mechanism and transported to the rear mechanism.

[0097] Example 7: Refer to Figure 7 The diagram below is a structural schematic of Embodiment 7 of this utility model. This embodiment discloses a cotton picking and conveying hinge. Compared with Embodiment 3, the difference in this embodiment is that the fixed rod 5-4 is connected to the drive shaft 5-6 through a connecting rod, and the connecting rod is provided in at least two sets.

[0098] Example 8: Refer to Figure 8 The diagram below is a structural schematic of embodiment 8 of this utility model. This embodiment discloses a cotton picking device. Compared with embodiment 1, the difference in this embodiment is that a hanging frame and a walking wheel 13 are provided on the cover 1. The hanging frame can be connected to the front end of the walking mechanism and driven by the walking mechanism to operate.
