BOOM TYPE SPRAYING MEANS Filed Jan. 4, 1960 2 Sheets-Sheet 2 IN V EN TOR. MPOZ KM/VSIZ Patented Sept. 25, 1962 ufacturing Company, Waverly, Nehr., a corporation of Nebraska Filed Jan. 4, 196i), Ser. No. 145 3 Claims. (Cl. Z39-161) This invention relates to a spraying apparatus and more particularly to a boom type spraying means adapted to be used on a moving vehicle such as a truck, tractor or like.
The use of boom type spraying means is old. They are used particularly for spraying weed killing chemicals and insecticides along the sides of roadways, over fence lines and like. However, such present equipment is lacking in eflicient control in that the boom spray means is not easily maneuver-able to conform with the changing terrain 1and obstacles over which the boom must pass. Also, if the boom has a plurality of adjustable hinged sections, the spr-ay pattern may well be erratic in the vicinity of the hinged joint or joints. v Furthermore, the present multi-section boom, while adjustable, cannot be adjusted from the vehicle or during the time the vehicle is in motion.
Therefore, one of the principal objects of my invention is to provide a boom type mobile sprayer that is under the complete control of the operator even when the sprayer is in travelling motion.
More specifically, the object of this invention is to provide a multi-section boom type sprayer that is capable of having al1 of its sections independently adjusted by a single operator riding on the vehicle that supports the sprayer.
A further object of this invention is to provide -a multisection boom liquid sprayer that will successfully complete -the desired uniform spray pattern even when the various sections extend in adjustment at diiferent angles to each other.
A still further object of this invention is to provide a boom type sprayer that is foldable into -a compact unit when not in actual use.
Still further objects of my invention are to provide a boom type liquid spraying means that is economical in manufacture and durable in use.
These and other objects will be apparent to those skilled in the art.
My invention consists in the construction, arrangements, and combination of the various parts of the de- Vice, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claims, and illustrated in the accompanying drawings, in which:
FIG. 1 is a side view of my boom type sprayer;
FIG. 2 isa diagrammatic side view of the device showing the method of lowering and raising the boom sections;
FIG. 3 is a diagrammatic side view showing the liquid spray means :and its association with the individual boom sections; and
FIG. 4 is an enlarged side view of the hinge joint area between two of the boom sections.
As will be appreciated by la study of these drawings, much of the operating cables and liquid conduits are housed within the boom sections. The liquid conduits 'are for both the spray phase and the passage of liquid to and from some of the hydraulic power cylinders. Obviously, at least -at the hinged joints of the boom sections, the conduit sections must be of flexible material such as hose lengths or like.
My boom is secured to a base on the vehicle. The rst section 11 of the boom has its inner end vertically hinged to a bracket `12 which in turn is horizontally hinged to the base 10. This particular feature of my device is not new and it is customary to connect'a hydraulic cylinder (not shown) to the bracket for swinging it in a horizontal plane. The numeral 13 designates an ordinary hydraulic power cylinder having its cylinder portion hinged to the bracket 12 and its piston extending outwardly and downwardly and hinged to the top of the boom section 11. The numeral 15 design-ates a liquid conduit communicating with the inside back of the cylinder and the numeral 16 designates a liquid conduit communieating with the inside front of the cylinder. These two conduits 15 and 16 are ladapted to be connected with the hydraulic pressure means of the vehicle and are controlled by the usual four-way valve means. The numeral 17 designates the second or middle boom section having its inner end vertically hinged to the outer end of the boom section 11. On the inner end of the boom section 17 and rigidly secured thereto is a pulley wheel 19. The numeral 20 designates an ordinary hydraulic power cylinder secured to the top of the boom section 1l and having its reciprocating piston shaft extending through both of its ends. The numeral 21 designates a rotatably mounted idler wheel on the rear end portion of the boom section 11. The numeral 22 designates a belt cable having one end secured to the forward end of `the piston shaft of the hydraulic cylinder 20, extending first forwardly, thence around the pulley wheel 19, thence rearwardly, thence around the idler 21, and thence forwardly where it is connected to the rear end of the piston shaft of the hydraulic cylinder 20. The numeral 25 designates a conduit communicating with the inside rear of the hydraulic cylinder 20 and the numeral 25 designates a conduit communicating with the inside forward end of the hydraulic cylinder 20. These two conduits 23j and 25 are adapted to be connected with the hydraulic pressure means of the vehicle and are controlled by the usual four-way valve means. The numeral 26 designates a third boom hydraulic power cylinder and is secured on the under side of the boom section 17. The numeral 27 designates the third, or outer boom section and has its inner end vertically pivoted to the outer end of the boom section 17. On the inner end of the boom section 27 and rigidly secured thereto is a pulley wheel 29. The numeral 30 designates an idler wheel rotatably mounted on the rear end portion of the boom 17. The numeral 31 designates a cable belt secured to the forward end of the piston shaft of the hydraulic cylinder 26, and which extends forwardly, thence around the pulley wheel 29, thence rearwardly, thence around the idler 30, and thence forwardly where it is secured to the rear end of the piston shaft of the hydraulic cylinder 26. The numeral 32 designates a conduit communicating with the inside rear of the hydraulic cylinder 26 and ythe numeral :i3I designates a conduit communicating with the inside front of the hydraulic cylinder 26. These two conduits 32 and 33 are 4adapted to be connected to the hydraulic pressure means of the Vehicle and are controlled by the usual four-way valve means. By this structure the first boom 11 may be vertically hingedly raised or lowered by the hydraulic power cylinder 20, and the second boom section 17 may be independently vertically hingedly raised or lowered by the hydraulic power cylinder 26. The outer boom section may be independently vertically hingedly raised or lowered by Ithe hydraulic power cylinder 26. Inasmuch as the conduits 15, 16, 23, 25, 32 and :i3` extend to the carrying vehicle, the operator on the vehicle will have complete control over all of the boom sections, even while the vehicle is in motion. The numeral 35 generally designates the liquid spray conduit means having the usual spaced apart liquid exit spray jets on its under side. This conduit 35 may be a common one extending under all of the boom sections 11, 17 and 27, or it may consist of three sections, i.e., one for each of the boom sections, so that the operator may have or eliminate the spray from -any one section. The liquid spray conduit means of course extends to the vehicle where it is in communication with a source of the liquid to be sprayed. As before noted, at the pivot area of each of the boom sections the conduit or conduits must be flexible to permit the independent movement of each of the sections. It has also been indicated that if the boom sections are at certain angles relative to each other, the spray pattern may not be uniform in the area of the hinge connection. Therefore, on each of the forward ends of the sections 11 and 17 I pivot a plate 36 having an arcuate slot 37. The numeral 39 designates a set screw extending through the slot 37 and threaded into the boom section adjacent to it. Mounted on this plate is a spray jet nozzle 40 connected to the spray liquid conduit by a flexible short conduit 41. By adjusting these plates on the boom sections, the two jets 40 may be adjusted to direct a liquid spr-ay at the joints between the first and second boom sections and the second and third boom sections to ll in `and successfully complete the spray pattern. Different adjustments will be necessary for different relative `angles of the boom sections, but this will be substantially reduced by the spray jets 40 moving with their respective boom sections.
Some changes may be made in the construction and arrangement of my boom type spraying means without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure of use of mechanical equivalents which may be reasonably included within their scope.
