Description

Technical Field

[0001] The utility model relates to the technical field of corn planting, in particular to an adjustable sowing device for planting. Background Art

[0002] Planting spreaders are commonly used in agricultural planting, which can evenly spread seeds on the field. The planting spreader can improve the sowing efficiency, ensure the uniform growth of crops, and reduce resource waste. At the same time, it also helps to reduce labor intensity and improve crop yield and quality.

[0003] When most of the existing planting sowing devices are in use, the seeds are directly dropped through a pipe to complete the sowing work. The space inside the pipe is not easy to adjust, and it is not easy to adjust the seed sowing spacing, resulting in a fixed number of seeds sown each time. The number of seeds sown cannot be adjusted according to actual needs, and the sowing effect is not good. For this reason, we propose an adjustable planting sowing device. Utility Model Content
