スプレーヤのノズルに関するものである。[Detailed description of the invention] This invention relates to the nozzle of a speed sprayer, and by making it possible to open and close an on-off valve for at least one of the plurality of nozzles formed in the nozzle, it is possible to perform more fine-grained pest control at a speed that enables finer control. It relates to a sprayer nozzle.

機８とが備えられる。 Generally, a speed sprayer as shown in FIG. 1 is used for pest control work in orchards and the like. This consists of a traveling device 2 that can run on wheels 1, and a drug tank 3 mounted approximately in the center of the traveling device 2.
and an arcuate pipe 5 connected to the drug tank 3 via the pump device 4 and disposed at the rear of the traveling device 2 so as to span from both sides to the top.
A plurality of nozzles 6 are arranged on the pipe 5 at appropriate intervals, a plurality of nozzles 7 are formed in the nozzles 6, and a medicine is sprayed from the nozzles 7 located behind the pipe 5. A blower 8 that spreads the air further is provided.

ぎて薬液が無駄に噴霧されるという問題がある。 The conventional nozzle 6 has a pipe-shaped nozzle main body 11, as shown in FIG. In addition, the nozzle ports 12 and 13 are formed on the distal side and the proximal side, respectively, and when spraying, the spray is always sprayed from the nozzles 12 and 13 at the same time, or the spray is stopped at the same time. It is becoming more and more like this. Therefore, depending on the size and shape of the tree, there is a problem that the spray range is too wide and the chemical solution is wasted.

This nozzle 6″ can be used instead of
20 is a plan view and a side sectional view showing the pipe 5, and in the drawing, 20 is a peripheral convex portion 21 formed at the base end portion of the pipe 5.
A connecting member 24, which is nut-shaped and has a threaded portion 22 screwed to the end thereof and has an engaging convex portion 23 formed along the inner circumference, rotates when the engaging convex portion 23 is engaged with the connecting member 24. It is a pipe-shaped nozzle body that can be attached. A spout 25 is formed on the side surface of the nozzle body 20 near the base end. In addition, the nozzle body 20
A tip closing member 26 is attached to the tip of the nozzle body 20 to close the tip opening 27 of the nozzle body 20. A nozzle 28 is formed on the side surface of the closing member 26 facing in the same direction as the nozzle 25 , and the nozzle 28 and the inside of the nozzle body 20 communicate with each other within the closing member 26 . A substantially T-shaped communication hole 29 is bored through the hole. A threaded portion 30 is formed at the tip of the communication hole 29, and
A valve seat 31 is formed in a portion communicating with the nozzle body 20. The threaded part 30 has a needle-shaped valve body 32 formed at its base end, a circumferential groove 34 in which an O-ring 33 is installed and a threaded part 35 at its intermediate part, and a threaded part 35 at its distal end. A valve body member 37 formed with a disk-shaped handle portion 36 serving as a means is attached to the threaded portion 3.
0 and 35 are screwed together, and the distal end of the communication hole 29 is closed in a watertight state by the O-ring 33, and the valve body 32 can be seated on the valve seat 31, and the distal end of the closing member 26 is closed. It will be installed.

More economical drug spraying is possible. Similarly, by closing the valve seat 31, the spray range can be narrowed and spray can be concentrated in a desired direction. Furthermore, the amount of the medicine sprayed from the nozzle can be freely changed, and the effect is that the appropriate amount of medicine can always be sprayed.
