More Information
Summary:The utility model discloses a variable deep-fertilizing precision seeder which belongs to the field of agricultural machinery and aims at providing a variable deep-fertilizing precision seeder that can control the fertilizing amount according to the local conditions and integrates the variable deep-fertilizing and precious seeding. The seeder adopts a parallel four-rod profiling mechanism, a spoon-rank precision seeder and a narrow-core furrow opener to realize row seeding of accurate seeding rate, single body profiling and single body driving, improve the penetration performance, reduce seeder slipping and ensure accurate seeding rate and row spacing. The variable deep-fertilizing system is driven by a hydraulic motor and combined with a speed measuring radar for measuring the speed, and the fertilizing is led to be more accurate and reliable through the control by a field computer.
