CONFIGURATIONS OF INLET AND OUTLETS OF AIR FILLED AUXILIARY TANK OF AIR SEEDERS

摘要

A system for replenishing the supply of a particulate agricultural product in the tank of an air cart. A mixture of air and product comes out of a venturi delivery system and enters in a multiplicity of inlet hoses. Then the product enters into inlet tubes of various lengths and release angles from which product particles are gently spread strategically forming a pile that is more or less horizontal to ensure even feeding of meters during dispensing operations. Then the air exits through one or more fine screens to avoid product escaping as well and is conveyed through the exhaust hoses until reaching an air diffuser. The air diffuser has a series of varying size holes or louvers at the bottom so the air can come out at a uniform low velocity which minimizes any discomfort to nearby operators.

主权项

1. A pneumatic agricultural product delivery system, comprising:
at least one product supply tank; a pneumatic source; a plenum normally receiving air flow from the pneumatic source and having a plurality of outlets; a plurality of distribution lines extending from the plenum outlets to a utilization implement for applying air entrained product to an agricultural field; a metering system for supplying product from the supply tank to the distribution lines; an air conveying system for occasionally receiving product from a supply source and delivering product to the tank to replenish the product supply in the tank, comprising;
an air flow source;a venturi region having an inlet and at least one venturi coupled to the air flow source, an inlet for receiving product from the supply source, and an outlet for providing product from the supply source entrained within air flow from the pneumatic source; anda plurality of supply conduits for receiving an air entrained product flow from the venturi box outlet and delivering the air entrained product flow to the product supply tank, each conduit extending into the product supply tank for releasing the air entrained product flow, at least two conduits releasing their respective air entrained product flows at different locations within the tank.
