PNEUMATIC SEED METERING UNIT FOR PRECISION SEEDERS

摘要

The invention relates to a pneumatic metering unit for a precision seeder, including: a hopper (1) with an oscillating base (2) and an adjustable hatch (4), as well as a vibration generator (3) in order to facilitate and control the flow of seeds from the hopper to the separation chamber; and a set of metering disks, formed by two identical, co-axial disks (5) which are offset in relation to one another and which are joined by means of a cylinder (13); and a central shaft (7) formed by a hollow tube provided with incisions (17), which is designed to convey suction and pressure from the dispenser (29, 30) to the disks (5) and a smooth cover (6) which is designed to define the seed separation chambers and to direct the seed to the desired location.
