Abstract
A material decelerating device is connected in series with a distribution tube in proximity to a material outlet in an agricultural air distribution system for decelerating conveying air which placing material into a furrow in the ground. The material decelerating includes an inlet tube connected to the distribution tube to receive material and conveying air therefrom. The inlet tube is connected at an intermediate location on a center tube of the device which exhausts the air upwardly to an exhaust opening and deposits the material downwardly through an outlet opening. A cap adjustably spans the exhaust opening to vary the amount of air exhausted. The inlet tube is inclined downwardly in alignment with a helical recessed channel within the center tube to guide material to the outlet.

A material decelerating device for use with an agricultural air distribution system having a distribution tube arranged for connection to a material outlet for placing material conveyed by air into a furrow, the material decelerating device comprising:
- a center tube extending in a longitudinal direction between an upper end and a lower end;
- an inlet tube having an upper end arranged to connect to the distribution tube and a lower end in communication with the center tube at an intermediate location between the upper and lower ends of the center tube so as to be arranged to deposit material and conveying air received from the distribution tube into the center tube;
- the lower end of the center tube having a lower opening therein and being arranged to communicate with the material outlet so as to be arranged to deposit material received from the inlet tube into the material outlet;
- the upper end of the center tube having an upper opening therein and being arranged to exhaust conveying air received from the inlet tube therethrough;
- and
- a cap portion including a guard member spanning across the upper opening at a location spaced above the upper end of the center tube so as to define a portion of the upper opening between the guard member and the upper end of the center tube;
- the cap portion being adjustable relative to the center tube so as to be arranged to vary a size of the upper opening.
