ABSTRACT:
Method and apparatus for transferring particulate matter, such as seed, from a bulk supply to planting apparatus such as a planter or drill utilizing a pneumatic conveyer system including a lightweight, portable rotary air lock for introducing the particulate matter into the pneumatic conveying system. The system further includes a blower for pressurizing the pneumatic conveyer line and a discharge device at a remote end of the pneumatic conveyor line for delivering the seed or other particulate matter directly into the seed boxes associated with the planting apparatus. An adapter is also included for coupling the lightweight rotary air lock to a bulk supply container such that the lightweight rotary air lock is held at a predetermined angle with respect to the vertical. Fixing the angle at which the lightweight, portable rotary air lock is held with respect to the vertical promotes a substantially complete fill of the rotary air lock device, maximizes seed transfer efficiency and minimizes the risk of damage caused by shearing effects within the rotary air lock.
