Description

Technical Field

[0001] The utility model relates to the technical field of cotton planting, and more specifically, to a self-propelled cotton spraying robot. Background Art

[0002] Cotton is the seed fiber of the genus Gossypium of the Malvaceae family. It is native to the subtropics and is one of the important economic crops in the world. It plays an important role in the economic development of China and the world. With the development of cotton planting industry, a cotton spraying mechanism is needed to improve the survival rate of cotton during its growth process.

[0003] When the cotton sprayer is running, since the vehicle body moves around the cotton field, and since the distance between each cotton planting area and the road surface is different, the spraying may not be fully covered or the spraying may be wasted.

[0004] After searching, a Chinese patent with publication number CN219593481U discloses a self-propelled cotton sprayer. Before use, the spraying angles of the nozzles on the left and right sides can be changed through an adjustment mechanism, thereby changing the spraying distance. This allows the sprayer to adapt to different distances between the planting area and the road surface during operation, thereby avoiding waste of pesticides during the spraying process.

[0005] When the above-mentioned self-propelled cotton sprayer is actually used, some cotton spraying mechanisms adopt fixed nozzles for spraying, resulting in that the cotton in some areas does not get enough liquid medicine, while other areas may be wasted or damaged due to excessive liquid medicine, resulting in uneven liquid spraying, which will affect the pest control effect of cotton. Utility Model Content

[0010] By adopting the above technical solution: using two spray pipes to drive multiple spray heads to swing, a wider range of coverage can be achieved, ensuring that the liquid medicine can be evenly sprayed on the cotton.

[0011] As a further description of the above technical solution: the mixing mechanism includes a servo motor, the servo motor is fixedly connected to the top of the mixing barrel, the upper surface of the mixing barrel is connected to a feed port, the output end of the servo motor is fixedly connected to a rotating shaft, a plurality of connecting rods are fixedly connected to the outside of the rotating shaft, one end of the connecting rod is fixedly connected to a spiral blade, the outside of the rotating shaft is fixedly connected to a connecting frame, and the bottom end of the connecting frame is fixedly connected to a plurality of scrapers.
