Abstract

The invention discloses a precision seeder for small-grain crops, which belongs to the technical field of agricultural machinery and comprises a frame fan system, a ditching and soil preparation system, a seed metering system, an opening fertilizer discharging system and a base fertilizer discharging system, a seed metering device in the seed metering system comprises a base, a seed metering component and a seed stirring component, and the seed metering component and the seed stirring component are positioned in the base. The seed metering assembly comprises a seed metering shaft, blank wheels and seed metering wheels, the blank wheels and the seed metering wheels are arranged on the seed metering shaft in a sleeving mode, each blank wheel and each seed metering wheel are each sleeved with a set of seed protection silica gel, and the outer ring of each seed protection silica gel is provided with a seed protection body meshed with the corresponding seed protection silica gel; a first spacing adjusting assembly is arranged below the seed discharging pipe and the outlet fertilizer discharging pipe, a second spacing adjusting assembly is correspondingly arranged below each base fertilizer discharging system, and the spacing of the base fertilizer discharging pipe of each base fertilizer discharging system is adjusted through the second spacing adjusting assembly. According to the seeder, the seeding stability and precision can be ensured through the seeding device, meanwhile, the seeding spacing is convenient to adjust, and the seeder can meet different seeding requirements.
