Background Wheat is one of main grain crops in China, and the sowing quality of the wheat directly influences the subsequent growth situation and the final yield. In wheat sowing operation, the row spacing is one of core planting parameters, and different soil conditions, climatic environments, wheat varieties and planting modes have obvious differences in the requirements on sowing row spacing. The reasonable row spacing configuration can ensure that wheat plants obtain sufficient illumination, moisture and nutrients, reduce competition among plants, promote group growth quality and further achieve the aim of increasing yield and income. Therefore, the row spacing adjusting function of the seeder is important for adapting to diversified planting requirements and improving universality and accuracy of seeding operation. At present, the row spacing adjustment mode of the wheat seeder in the prior art is mostly manual adjustment, and in a specific operation process, an operator needs to stop firstly, then the row spacing is changed by disassembling and replacing parts (such as connecting pieces between seeding monomers, replacing seeding discs with different spacing, and the like), and the equipment is restarted to seed after the adjustment is completed. The manual adjustment mode is complex in operation, time-consuming and labor-consuming, adjustment accuracy depends on experience of operators, row spacing deviation is easy to occur, and sowing quality is affected. And the manual adjustment mode can not adjust the row spacing in real time in the sowing process, when the row spacing requirement of different plots needs to be adapted, the adjustment must be stopped for a plurality of times, thereby greatly reducing the sowing operation efficiency and increasing the operation cost.
