A seeder, comprising a material feed tank (1), a conveying device (2), a material extractor (3), a soil-gathering plough (4), a frame (5), wheels (6), a drug outlet (7), a drug dispenser (8), a drug feed tank (9), a transmission shaft (11), a soil-covering plough (12), a cover film roller (13), soil-covering shovels (14), a material outlet (15), and a blocking plate (16). The material outlet (15) is connected to the blocking plate (16), the drug dispenser (8) is arranged within the drug feed tank (9) and connected to a rotary disk on the transmission shaft (11) via a belt, the cover film roller (13) is fixed on the frame (5) and located between the soil-covering plough (12) and the soil-covering shovels (14), the material feed tank (1) is in the shape of an inverted funnel having a large top and a small bottom, the material outlet (15) and a bottom opening of the material feed tank (1) are both sealed by an elastic filament, the rotary disk on the transmission shaft (11) is matchedly connected to a driven shaft on the conveying device (2) via a belt or a chain, a fixed block is arranged at the junction of the material extractor (3) and a conveying belt (10), and tank openings of the material feed tank (1) and the drug feed tank (9) are both provided with tank covers. The seeder is used for tuber crop seeding, the structure is simple, seeding is uniform, and the operational efficiency is high. The seeder may replace human labour, and is suitable for promotion and use. |
