The realization of precision seeding technology mainly relies on advanced seeding device technology. The precision seeding devices currently used can be divided into two types according to technical principles: mechanical and air-suction seeding devices; mechanical seeding devices are currently more commonly used, but the mechanical structure of mechanical seeding devices is complex and prone to mechanical failures. At the same time, mechanical seeding devices need to be synchronized with the power system of the tractor to achieve the effect of precision seeding of mechanical seeding devices.

[0003] When sowing, if the seeds are sown side by side, the crops will be too crowded after growing, and they will not be able to receive sunlight and water well, which will limit the growth of crops. Existing sowing equipment requires high precision to stagger the seeds of crops. Ordinary mechanical sowing and air-blowing sowing cannot achieve accurate staggered sowing, which will cause the crops to be crowded and cannot grow well. Utility Model Content
