Abstract

A spraying apparatus for mechanized spraying from a vehicle includes a supply for providing a sprayable material, air supply elements, and spray elements. The supply unit is adapted to provide pressurized flow. The air supply is operatively connected to the spray elements and the supply unit is operatively connected to the spray elements such that the sprayable material is sprayed from the spray elements in conjunction with air from the air supply unit. The apparatus is adapted to be removably connected to any vehicle. The apparatus can also include a spray boom apparatus for mechanized application of a pressurized spray. The spray boom apparatus includes a non-air spray boom for spraying pressurized non-air material and an air spray boom for spraying pressurized air. The air assists the non-air spray to hit specified targets by increasing spray areas and depth.

Claims

1. A spraying apparatus for mechanised spraying from a vehicle comprising a supply means for providing a sprayable material, air supply means, and spray means, the supply means being adapted to provide pressurised flow, the air supply means being operatively connected to the spray means and the supply means being operatively connected to the spray means such that the sprayable material is sprayed from the spray means in conjunction with air from the air supply means wherein the apparatus is adapted to be removably connected to a vehicle.

2. The spraying apparatus as claimed in claim 1 wherein the sprayable material includes pollen which is in the form of a suspension.

3. The spraying apparatus as claimed in claim 2 wherein the air supply means includes a blower to produce pressurised air to assist in directing the sprayable material to where it is needed.

4. The spraying apparatus as claimed in claim 3 wherein the air supply means includes an air curtain boom wherein the air curtain boom has a structure that allows the air to exit therefrom.

5. The spraying apparatus as claimed in claim 4 wherein the air curtain boom can include at least one adjustable air bar wherein the air bar is apertured to allow the air to exit therefrom.

6. The spraying apparatus as claimed in claim 5 wherein the air supply means is operatively connected from the blower via tubing to the air bar.

7. The spraying apparatus as claimed in claim 6 wherein the spray means includes a spray boom and the spray boom includes at least one spray bar with at least one nozzle to allow a liquid spray to exit therefrom.

8. The spraying apparatus as claimed in claim 7 wherein the spray supply means is operatively connected to the spray boom.

9. The spraying apparatus as claimed in claim 8 wherein the spray supply means is a tank.

10. The spraying apparatus as claimed in claim 9 wherein the air curtain boom is supported by the spray boom.

11. The spraying apparatus as claimed in claim 9 wherein the air curtain boom is separately supported by its own support structure.

12. The spraying apparatus as claimed in claim 10 wherein support means supports the air bar and/or the spray bar and the support means is a stem adapted to allow spray and/or air therethrough.

13. The spraying apparatus as claimed in claim 12 wherein the support means and/or spray bar and/or air bar are adjustable to enable rotation and/or tilting and height adjustment.

14. The spraying apparatus as claimed in claim 13 wherein a compressor is operatively connected to the tank to pressurise the pollen exiting therefrom.

15. The spraying apparatus as claimed in claim 14 wherein the apparatus includes a guard rail to protect the air bar and spray bar being connectable to the stem or spray bar or air bar, pressure switching, solenoid control switching and liquid control solenoids to assist in the movement of the pollen in the tank to the spray boom and air curtain boom.

16. A spray boom apparatus for mechanised application of a pressurised spray, the apparatus including a non-air spray boom for spraying pressurised non-air material and an air spray boom for spraying pressurised air, wherein the air assists the non-air spray to hit specified targets by increasing spray areas and depth.

17. A spray boom apparatus as claimed in claim 16 wherein the boom is able to be adjustably orientated and to be constructed and adapted to be connected to and supported by, a vehicle.

18. The spray boom apparatus as claimed in claim 17 wherein the spray boom includes at least one spray bar having at least one aperture to allow the spray which is a suspension to exit therefrom.

19. The spray boom apparatus as claimed in claim 18 wherein an air supply means is adapted to provide pressurised air and the air is provided adjacent to the spray bar whereby air can be delivered to assist in the directional effectiveness of the spray or spray hits, exiting the spray bar.

20. The spray boom apparatus as claimed in claim 19 wherein the air supply means comprises a separate boom being provided by at least one air bar having at least one aperture to allow air to exit therefrom.

21. The spray boom apparatus as claimed in claim 20 wherein in use the air bar is located parallel and behind the spray bar.

22. The spray boom apparatus as claimed in claim 21 wherein support means supports the air bar.

23. The spray boom apparatus as claimed in claim 21 wherein support means supports the spray bar.

24. The spray boom apparatus as claimed in claim 21 wherein the support means and or spray bar and/or air bar are adjustable to enable rotation and/or tilting and height adjustment.

25. The spray boom apparatus as claimed in claim 24 wherein the apparatus includes a tank for the storage of the spray and a guard rail joined to the bars to protect them from damage or entanglement with any obstacles.

26. The spray boom apparatus as claimed in claim 25 wherein the apparatus includes a compressor being operatively connected to the tank to allow the spray to be pressurised.

27. The spray boom apparatus as claimed in claim 26 wherein the air supply means includes a blower which can be operatively connected to the air boom to produce pressurised air which is in use sited behind the spray boom to the enable the pressurised spray to be directed to the area or plant requiring spraying.
