成果简介	NOVELTY - The system has a seed plate (20) dividing a casing into a seed side and a vacuum side. The seed side is being segmented into a seed holding area and a seed drop area. The seed holding area receives seeds from a hopper. An inlet port admits a first air stream into a vacuum generator. A suction port (14a) selectively admits a second air stream from the vacuum side into the vacuum generator, where the first air stream and the second air stream being caused to form a pressurized air in the vacuum generator. A bleed line connects an outlet port to the hopper. The bleed line is being configured to tap a desired volume of the pressurized air. USE - Vacuum system for a seed metering unit i.e. pneumatic seed meter, that is utilized for sowing or depositing seeds with regular spacing on a location where crops are required to be grown. ADVANTAGE - The system reduces entire cost of utilizing the seed metering unit, and requires low maintenance, and is easy to operate. The system maintains appropriate spacing between seeds during sowing to reduce or eliminate excessive amount of labor involved in thinning rows of crops after germination, and ensures supply of required quantity of nutrients necessary for proper growth of the seeds into healthy crops. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a vacuum system for a seed metering unit. 14aSuction port 20Seed plate 22Seed picker 24Annular rim 28Segmenter
