Seed feeder

Abstract

Abstract PURPOSE:To let fed seeds be separated granules and to make seeding intervals constant, by vibrating a slantingly set seed adjusting conduit by an oscillating mechanism. CONSTITUTION:Seeds A are stored in a seed hopper 1 and each given amount of the seeds A is discharged from an outlet 1a. The discharged seeds are sent to a seed feed end 2a of a first seed adjusting conduit 2. Since the seed adjusting conduit 2 is loosely sloped and is vibrated by an oscillating device 3, the seeds are made to flow toward a seed outlet end 2b and separated into each granule in the process of flow. The separated seeds are fed to a second seed adjusting conduit 4. The seeds dropping from the seed outlet end 2b are detected by a seed sensor 6, the angle of inclination of the seed adjusting conduit 2, the amplitude and intensity of the oscillating device 3 are controlled depending upon the amount of the seeds dropped. The intervals of the seeds are further made constant by the second seed adjusting conduit 4.
