[0007]
[Problems to be solved by the invention]
By the way, in the conventional nozzle structure, it is necessary to replace the nozzle pipe 9 while considering the fog interference with the next nozzle 11 when changing the number of the nozzles 11, which causes a high cost.
[0008]
In addition, the nozzle 11 was not given a degree of freedom to swing the head only in the substantially circumferential direction of the jet head 7 (adjustment of the nozzle discharge direction could only be performed in the circumferential direction), and could not be performed in the front-rear direction of the drug spraying vehicle 10.
[0009]
The present invention has been made in view of such conventional problems, and provides a nozzle structure capable of easily adjusting the number of nozzles and adjusting the spray density and spray balance, and a drug distribution vehicle equipped with the nozzle structure. For the purpose.
[0010]

[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described. FIG. 1 shows a configuration diagram of an embodiment of the present invention. Note that the same components as those in FIG. 6 are denoted by the same reference numerals and description thereof is omitted. In FIG. 1, the nozzle pipe 9 has a plurality of pipe connection ports 13 arranged at equal pitches. A male screw 15 projects from the pipe connection port 13.
[0022]
In the nozzle adapter 20, a pipe 23, a pipe 25, and a pipe 27 are connected in a substantially T shape by a connecting member 24. However, the pipe 23 and the pipe 25 may be used as one pipe.
[0023]
A nut 21 is passed through the pipe 23, and a pipe line is folded back radially outward at a left end (not shown) of the pipe 23. A packing 31 is brought into contact with the folded portion, and the nut 21 is screwed onto the male screw 15.
[0024]
A male screw 33 and a male screw 35 are engraved at the ends of the pipe 25 and the pipe 27, respectively. A nozzle 39 is fixed to one end of the nozzle support pipe 37, and a pipe line is folded back radially outward at the other end. A packing 41 is brought into contact with the folded portion, and the nut 43 is screwed onto the male screw 33.
[0025]
The same applies to the pipe 27 side. A nozzle 47 is fixed to one end of the nozzle support pipe 45, and a pipe line is folded back radially outward at the other end. A packing 49 is brought into contact with the folded portion, and the nut 51 is screwed onto the male screw 35.
[0026]
In addition, it is also possible to attach the bidirectional nozzle 53 shown in FIG. In the bidirectional nozzle 53, for example, nozzle openings 55a and 55b having different opening diameters are provided. The nozzle support pipe 57 is inserted inside the nozzle opening holding pipe 59.
[0027]
The nozzle opening holding pipe 59 is rotatable around the nozzle support pipe 57. The rotation of the nozzle opening holding pipe 59 is stopped by a stop ring 61.
[0028]
A through hole (not shown) is provided at the upper portion of the nozzle support pipe 57, and this through hole is formed for the nozzle openings 55a and 55b. For example, in the case of FIG. 2, spraying is possible only from the nozzle opening 55a facing the through hole.
[0029]
If the positions of the nozzle opening 55a and the nozzle opening 55b are reversed, spraying is possible only from the nozzle opening 55b, and if the nozzle openings 55a and 55b are further rotated 90 degrees from the position of FIG. The spraying is stopped for both the openings 55a and 55b.
[0030]
At the end of the nozzle support pipe 57, the pipe line is folded back outward in the radial direction. A packing 49 or a packing 41 is brought into contact with the folded portion, and the nut 63 is screwed into the male screw 35 or the male screw 33.
[0031]
FIG. 3 shows a jet head structure when the bidirectional nozzle 53 is attached to the nozzle adapter 20.
[0032]
Next, the operation of the embodiment of the present invention will be described.
According to this configuration, the number of nozzles can be easily increased using the existing nozzle pipe 9. In this case, since it is not necessary to use the existing nozzle pipe 9 and make other changes, the cost can be reduced.
[0033]
In FIG. 1, since the nozzle 39 is rotatable around the nut 43, the radiation angle in the circumferential direction of the nozzle can be adjusted. On the other hand, since the nozzle 47 is rotatable around the nut 51, the radiation angle in the longitudinal direction of the machine body can be adjusted.
[0034]
This makes it easy to adjust the spray density and spray balance. In the case where it is desired to apply a partly dense spray such as a shelf, it is possible to easily increase the number of nozzles by using the nozzle adapter 20 partly.
[0035]
Further, when the nut 21 is screwed into the male screw 15, the pipe 23 can be rotated with respect to the nut 21, so that the arrangement position of the pipe 27 can be reversed 180 degrees from the state of FIG. At this time, the position of the nozzle 47 may be reversed around the nut 51, and the position of the nozzle 39 may be reversed around the nut 43.
[0036]
Various spray adjustments are possible using this technique. For example, as shown in FIG. 4, in the state where all the pipes 27 are aligned leftward, the nozzle 47C1 is disposed between the nozzle 39C1 and the nozzle 39A4, and water is supplied from the nozzle pipe 9C side. The nozzle 39 and the nozzle 47 are arranged in a staggered pattern.
[0037]
The nozzle pitch of the nozzles 39 is determined in advance so that no fog interference occurs between the adjacent nozzles 39. Therefore, it is difficult to add a new nozzle between adjacent nozzles 39.
[0038]
However, by arranging in a staggered manner in this manner, interference of fog between adjacent nozzles (adjacent nozzle 39 and nozzle 47) can be avoided. Between the adjacent nozzles 47 is also the same pitch as the nozzle pitch of the nozzle 39, so there is no possibility of fog interference. In this case, since it is not necessary to adjust the nozzle pitch between the nozzles 47 again, it is simple.
[0039]
On the other hand, as shown in FIG. 5, the nozzle adapter 30 at the left end of the nozzle pipe 9C stops the T-shape and is a straight type. The nozzles 47C2 to 47C4 are aligned toward the left as in FIG. 4, and the nozzles 47A1 to 47A4 are aligned toward the right.
[0040]
At this time, a nozzle 47A4 is disposed instead of the nozzle 47C1 at the position of the nozzle 47C1 in FIG. 4 between the nozzle 39C1 and the nozzle 39A4, and water is supplied to the nozzle 47A4 from the nozzle pipe 9A side.
[0041]
As described above, the nozzle pipe for water supply can be easily changed, and the spray range can be changed without changing the spray density.
[0042]
If the bidirectional nozzle 53 is used instead of the nozzle 39 and the nozzle 47, the opening diameter can be selected and spraying can be stopped. For this reason, the freedom degree further increases with respect to the change of a spray density or a spray range. For example, if the unnecessary nozzles are stopped, it is possible to easily change the spray density partially.
[0043]
In addition, when the jet head structure has a two-stage configuration of the nozzle 39 group and the nozzle 47 group, an air guide plate (not shown) is provided so that the wind from the blower 5 is divided into units and supplied. Is desirable. This reduces the risk of further fog interference.
[0044]
Although the present invention has been described as a jet head structure, it can also be applied as an attachment of a nozzle group of a cleaning device such as a tunnel.
[0045]
【The invention's effect】
As described above, according to the nozzle structure of the present invention, the first pipe (23, 25), the first nozzle (39, 53), and the second nozzle (47, 53) can be rotated. Therefore, the spray direction can be changed freely so that the fog reaches any point of 360 degrees.
[0046]
Further, the number of nozzles can be freely increased where necessary without changing the existing nozzle pipe.
[0047]
Furthermore, when this nozzle structure is applied to a medicine spraying vehicle, it is possible to adjust the radiation angle in the circumferential direction of the jet head and the radiation angle in the longitudinal direction of the aircraft, It is easy to adjust the spray density and spray balance from the drug sprayer. For this reason, fine spraying becomes possible and the control effect can be enhanced.
