Abstract

A spray device includes a valve assembly, in inlet pipe, an extension tube, and a spray tip. The valve assembly includes an inlet, an outlet, and a seal between the inlet and the outlet. A force applied to an actuator pivotably connected to the valve assembly forces the seal away from a sealing position, and allows a pressurized fluid to move from the inlet to the outlet. The fluid exits the outlet, and enters a passage in the extension tube. The spray tip includes a substantially vertical slot that communicates with a passage. The passage of the extension tube further communicates with the passage of the spray tip, thereby forcing the fluid to exit the slot in a wide uniform spray. A second embodiment provides an extension tube including a bend for delivery of the pressurized fluid closer to a ground surface.

Claims

1. A spray device, comprising:

a valve assembly, including an inlet coupled with a fluid source and an outlet; and

a spray tip coupled to the outlet of the valve assembly, the spray tip comprising a housing including a passage in communication with a substantially vertically oriented slot, whereby a fluid is delivered through the passage of the spray tip to the vertically oriented slot, and exits spray tip in a wide vertical spray pattern.

2. The spray device according to claim 1, wherein the slotted end of the spray tip includes a taper.

3. The spray device according to claim 2, wherein the slot is aligned with the apex of the taper.

4. The spray device according to claim 3, wherein the slot extends beyond the taper.

5. The spray device according to claim 1, further comprising:

an extension tube coupled to the outlet and the spray tip, the extension tube including a passage in communication with the outlet, and the passage of the spray tip, whereby the fluid is delivered through the passage of the extension tube to the passage of the spray tip to exit the slot in a wide flat spray pattern at a prescribed distance from an operator.

6. The spray device according to claim 5, wherein the extension tube is in the range of twelve to twenty-four inches in length.

7. The spray device according to claim 5, wherein the extension tube includes a bend to allow the application of the fluid from a service vehicle.

8. The spray device according to claim 7, wherein the bend in the extension tube is approximately sixty degrees.

9. The spray device according to claim 1, wherein the spray device delivers a thrust force to counteract the weight of the spray device.

10. The spray device according to claim 1, wherein the fluid source is pressurized for delivery through the spray device.

11. The spray device according to claim 1, wherein the product source is secured to a service vehicle.

12. A spray tip, comprising:

a housing including a passage, and

a slot in communication with the passage, wherein a pressurized fluid is delivered to the passage, and further wherein, the pressurized fluid moves through the passage to exit the slot in a wide substantially vertical spray pattern.

13. The spray tip according to claim 12, wherein the second end includes a conical taper to extend the width of the spray pattern.

14. The spray tip according to claim 13, wherein the slot is located in alignment with an apex of the conical taper.

15. The spray tip according to claim 12, wherein the depth of the slot extends past the taper.

16. The spray tip according to claim 12, wherein the slot is oriented vertically to provide an even distribution of fluid along a vertical plane.

17. A method of delivering a wide spray pattern from a spray device, comprising:

a. actuating a valve assembly to permit a pressurized flow of a fluid from an inlet to an outlet, the outlet coupled to a spray tip including a passage communicating with a slot, wherein, the fluid passes into the passage in the spray tip to the slot, and further wherein, the slot is oriented substantially vertical; and

b. delivering the fluid through the substantially vertical slot, and onto desired vegetation in a wide vertical spray pattern.
