Abstract
The present disclosure relates to a system and method for spraying one or more target objects. A primary blower system is adapted to create a relatively isolated field of circulating air by creating a primary air stream around the field of circulating air. A secondary blower system is adapted to circulate air within the isolated field by flowing a secondary air stream in directions contrary to the primary air stream. A chemical spray comprising liquid, aerosol droplets, particulate matter, or the like may be emitted into the circulating air within the field and thereby deposited on target objects within the field. Embodiments of the present disclosure may be used for agricultural, automotive, aerospace, and other applications to emit, contain, and/or recapture a spray.
Claims18
An apparatus for spraying a target object, comprising:
- a primary blower adapted to direct a first flow of air through a nose member, wherein the nose member comprises multiple radially-distributed air vents, wherein the radially-distributed air vents are adapted to direct the first flow of air in a first direction;
- a primary air intake vent, wherein the primary air intake vent draws in at least a portion of the first flow of air, thereby creating a first flow field envelope extending from the primary blower to the primary air intake vent;
- and
- a secondary blower adapted to direct a second flow of air within the first flow field envelope created by the primary blower and the primary air intake vent.
An apparatus for creating a field that may be shielded from ambient air, comprising;
- a nose member including air vents, wherein the air vents comprise pass-through holes in the nose member;
- a primary blower, wherein the primary blower directs a first flow of air in a first direction through the air vents;
- a primary air intake vent, wherein the primary air intake vent draws in at least a portion of the first flow of air, thereby creating a first flow field envelope extending from the primary blower to the primary air intake vent;
- a secondary side vent;
- a secondary central vent;
- and
- a secondary blower, wherein the secondary blower directs a second flow of air within the first flow field envelope created by the primary blower and the primary air intake vent.

- a primary air intake vent, wherein the primary air intake vent draws in at least a portion of the first flow of air, thereby creating a first flow field envelope extending from the primary blower to the primary air intake vent;
- a secondary air pipe;
- and
- a secondary blower adapted to direct a second flow of air within the first flow field envelope created by the primary blower and the primary air intake vent.
