[0002] Currently, Chinese patent CN209609245U discloses a novel cotton harvesting device, including a harvesting shovel. The bottom of the harvesting shovel has a regular groove, and a rotating seat is fixedly installed on the inner bottom wall of the shovel. A rotating column extending through to the top of the rotating seat is fixedly installed on the top of the rotating seat. A fixing ring located inside the harvesting shovel is fixedly installed on the outside of the rotating column, and a cotton separating rod is fixedly installed on the outside of the fixing ring. Drive shafts are fixedly installed on both the left and right sides of the harvesting shovel. This novel cotton harvesting device effectively solves the problem of time-consuming and labor-intensive cotton harvesting in some large-scale cotton-growing areas by setting a fixing frame on the connecting shaft to prevent it from falling off, and by setting a steering gear on the drive shaft to drive the connecting shaft to move when the drive shaft rotates.
[0003] Cotton picking devices are agricultural equipment used to efficiently separate and collect cotton fibers from cotton plants during the cotton ripening season. They work by using specific components to separate cotton from bolls, leaves, and other impurities, reducing the labor intensity of manual picking and improving cotton harvesting efficiency. They are widely used in the harvesting stage of large-scale cotton planting. However, most existing cotton picking devices rely on manual carrying or pushing, increasing the physical burden on pickers. They are not suitable for long-term operation, and it is difficult to flexibly adjust the working distance and angle during picking. They also have poor adaptability to cotton plants in different growth stages, which can easily lead to missed picking or inconvenient operation, affecting overall picking efficiency and making them inconvenient for users.

A negative pressure suction structure 3 is fixedly connected to the top of the electric trolley 1. A hand handle 4 is provided on the top of the negative pressure suction structure 3. A picking mechanism 2 is provided at the bottom of the hand handle 4. A transmission pipe 5 is movably connected to the right side of the picking mechanism 2. The left side of the transmission pipe 5 is movably connected to the right side of the negative pressure suction structure 3. A discharge component 6 is fixedly connected to the left side of the negative pressure suction structure 3.
[0024] In this utility model's technical solution, by setting up an electric trolley 1, a negative pressure suction structure 3, a handheld lever 4, a picking mechanism 2, a transmission pipe 5, and a discharge component 6, the entire equipment can be easily moved using the electric trolley 1, reducing the physical exertion of picking personnel carrying the equipment and lightening the burden for long-term operations. Workers can flexibly adjust the working distance and angle of the picking mechanism 2 using the handheld lever 4 to adapt to the picking needs of cotton plants of different heights and distributions, improving operational flexibility.

[0029] Additionally, please refer to Figure 7The surface of the handheld lever 4 is movably connected to a limiting component 12, and the inner wall of the limiting component 12 is movably connected to the surface of the transmission tube 5. In this embodiment, by setting the limiting component 12, the transmission tube 5 is supported and positioned, preventing the transmission tube 5 from falling off or bending due to shaking or pulling during operation, ensuring the smooth flow of cotton transmission, and reducing cotton blockage caused by displacement of the transmission tube 5.
[0030] Additionally, please refer to Figure 6 A fixing plate 13 is bolted to the top of the negative pressure suction structure 3, and a support block 14 is fixedly connected to the top of the fixing plate 13. In this embodiment, by setting the fixing plate 13 and the support block 14, the fixing plate 13 is fixed in use by the position of the support block 14.
