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.

A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.

A transfer pump for moving pellets of adhesive includes a pump housing with an adhesive inlet coupled to a supply hopper, an adhesive outlet coupled to an outlet hose, and an adhesive passage extending between the adhesive inlet and the adhesive outlet. A first air nozzle communicates with the adhesive passage adjacent the adhesive inlet and expels a first air jet that pushes pellets of adhesive through the adhesive passage. A second air nozzle communicates with the adhesive passage between the adhesive inlet and the adhesive outlet and expels a plurality of second air jets that draw pellets of adhesive through the adhesive passage by a vacuum force. The first and second air nozzles prevent clogging of pellets in the adhesive passage and enable movement of larger pellets than either air nozzle individually.

Seed on-demand system for granular material comprising at least one storage container for granular material, at least one fan to provide a conveyor air flow, and a distributing device with a distributor housing which is designed to receive material from the storage container by means of a material inlet opening and has a conveyor air opening to direct the conveyor air flow in the direction of the material received to generate a mixed flow of conveyor air and material, and at least one distributing segment which forms at least one first conduit with a first receiving opening and a first outlet opening, wherein the conduit is arranged to receive at least a part of the mixed flow by means of the receiving opening and to discharge it from the outlet opening. To avoid disturbances in the distribution of the material and simultaneously generate the mixed flow in an energy-efficient manner, it is provided that at least one stirring element is arranged between the material inlet opening and the first receiving opening to loosen the material in the area where the conveyor air flow is directed onto the material.

A feed wheel is provided that includes a body, a plurality of material ports formed in the body, and a plurality of outer pressure ports formed in the body. The body is operable to rotate about a central axis. The material ports are operable to receive material. The outer pressure ports are positioned radially outward in relation to the material ports. Each of the outer pressure ports is operable to receive pressurized gas when in registration with a pneumatic supply as the body rotates about the central axis. Each of the outer pressure ports are in fluid communication with a corresponding material port such that when an outer pressure port receives the pressurized gas, the pressurized gas discharges the material from the corresponding material port s out of the top surface of the body.
