Most hole-type and finger-clamping seed sowing devices are adopted for sowing in a hole sowing mode, but the sowing monomer adopting the hole-type and finger-clamping seed sowing devices does not have a zero-speed seed feeding function, so that the uniformity of seed distances after sowing is poor, and although some manufacturers consider adding zero-speed seed feeding devices, the manufacturing cost is increased, and the people cannot accept the zero-speed seed feeding devices. In recent years, with the improvement of the technological level of agricultural technology, precision hole sowing has the advantages of improving field permeability, photosynthetic leaf area and group photosynthetic production capacity, improving the quality of crops and improving the final yield of the crops. Although the operation machines have been developed for the advantages of precision hole sowing operation, the existing hole sowing machines do not have the zero-speed seed throwing function due to the structural design defect, the precision of the seed spacing and the sowing depth is difficult to ensure during operation, the sowing uniformity is poor, the growth of crops is influenced, and finally the yield is reduced.
