Definitions

  • the present invention relates in general to crop spraying devices. More particularly, the invention relates to an interchangeable and adjustable crop spraying manifold for use with an air blower agricultural crop sprayer.
  • a wide variety of agricultural crop sprayers for use in spraying liquids, to include fertilizers and pesticides, onto crops are known.
  • One well known type of crop sprayer is a boom-type crop sprayer which utilizes an elongate boom or series of booms extending from or towed by a tractor, respectively, having a spray boom positioned above and carried over the crops to be treated.
  • These boom-type crop sprayers are provided with a series of spaced spray nozzles which face downwardly from the boom for directing the substance sprayed therethrough toward the crops.
  • An example of this type of crop sprayer is disclosed in U.S. Patent Nos. 4,746,065 and 4,629,123, respectively, which devices are commonly used with planted row crops.
  • a second commonly used type of crop spraying device is an air powered crop spraying device.
  • These types of sprayers utilize a fan or an air blower adapted to draw air from between the crop rows and in a direction parallel thereto, and to direct the air against a back plate provided as a part of the blower unit so that the air is dispersed in a 360 degree radial pattern from and about the blower. In this manner at least some of the sprayed liquid is directed toward and received by the crops being treated.
  • Some attachments are available for the blowers of these crop sprayers, however these attachments are typically not adjustable, are intended for use in only attachment specific applications, and are not universally adaptable to the many types of air blower crop sprayers in use.
  • an air blower crop sprayer and more particularly a manifold for use therewith, that can be selectively positioned on the air blower for accurately directing a crop spray toward the crops being treated without the degree of randomness associated with the current devices.
  • the need also exists for such a manifold that can be quickly fit and/or retro-fit on these air blower crop spraying devices, and which can be quickly interchanged or exchanged with additional and separate manifolds tailored for the intended spray application.
  • a manifold which may be adapted for use in a wide variety of spray applications, to include not only planted row crops, but for use in orchards as well.

  • the manifold of this invention is provided with a first planar end plate having an opening defined therein, with a first annular mounting flange extending along the periphery of the opening, and a second, spaced and parallel end plate having a second annular mounting flange facing the first mounting flange.
  • the second mounting flange corresponds in size and shape to the first mounting flange, and is coaxial therewith about a longitudinal axis passing through both of the end plates.
  • the two end plates of the manifold will be mounted on the crop spraying device, and are positioned with respect to the air blower thereof.
  • the manifold also includes an elongate duct member for being received on the end plate mounting flanges.
  • the duct member is comprised of a first body portion and a second body portion. These two respective body portions of the duct member are constructed and arranged to be releasably mated to one another through the use of at least one, and preferably a pair of over center quick-release latch clamps mounted on the respective body portions of the duct member so that the body portions capture the respective mounting flanges of the end plates therebetween when clamped or mated together, and will thus position the duct member on the mounting flanges of the end plates.
  • the duct member is also capable of being selectively rotated on the end plate mounting flanges by opening or releasing one of the quick release clamps such that the duct member may be selectively rotated on, or slid over, the mounting flanges and about the axis of the end plates, and into at least one radial position extended about the longitudinal axis.
  • the duct member also defines an exhaust port extending for substantially its length.
  • An elongate liquid supply tube is provided as a part of the manifold, and is positioned to extend along at least a portion of the length of the manifold exhaust port.
  • the liquid supply tube includes a series of spaced spray nozzles, for example flip nozzles, in sealed communication therewith.
  • the spray nozzles are positioned within the exhaust port such that they face away from the duct member so that as an airflow is directed through the manifold and its duct member, and as the liquid to be sprayed is passed from the spray nozzles into the airflow, a mist or spray of the liquid is created and passed from the manifold.
  • the spray can be selectively directed toward the crops to be treated, as desired, by rotating the manifold on the end plate mounting flanges, as described above.
  • the manifold of this invention is intended for use with an air blower agricultural crop spraying device.
  • the crop spraying device may thus include a transportable frame constructed as a trailer and on which at least one ducted fan is mounted, the fan being suitably powered for generating an airflow to be passed through the manifold.
  • An air chamber formed within and by the manifold of the invention is placed in fluid communication with the ducted fan.
  • the crop spraying device will also include a supply of the liquid to be sprayed thereby, with a pump, also suitably powered, for passing the liquid to the liquid supply tube mounted on the manifold.
  • the airflow generated by the fan is passed into the air chamber of the manifold and is subsequently passed into and through the duct member, exiting the duct member through its exhaust port.
  • the liquid to be sprayed is passed through the spray nozzles and into the airflow for spraying the desired crops.
  • each manifold is constructed and arranged to separately capture the mounting flanges of its respective end plates for being separately positioned on the crop sprayer, and is also constructed to be separately rotated about its respective longitudinal axis.

  • the manifold of this invention therefore, allows for the spray pattern to be defined by the duct configuration, and allows for much greater directional control of the spray than is available with the known types of air blower crop spraying devices. Moreover, if damaged, the manifolds, either the end plates, and/or the duct members thereof, can be easily replaced without requiring any extensive modification of the crop spraying device.
  • the respective manifolds 5, 62 illustrated in Figs. 1 through 13 can be fashioned of any suitable material, either plastic or metal, although stainless steel is preferred for its resistance to the corrosive effects of the materials being sprayed by the crop spraying device, and for its endurance in an outside environment.
  • Any suitable plastic or fiberglass materials, for example, which is also capable of resisting the corrosive effects of the materials being sprayed with the crop spraying device, and which are adapted for outdoor service, may also be used.
