[0010]
The structure of the water discharge pipe of the present invention will be described.
The water discharge pipe 10 of the present invention is attached to a rotating (or swinging) water spray control machine used for pest control work such as orchards or watering work, and communicates with the tip of a water supply pipe or water supply hose. In the rotary water spray control machine, the water discharge pipe 10 is detachably attached to a rotation mechanism section with the vertical direction as an axis.
The water discharge pipe 10 includes a nozzle pipe 1 communicating with a water supply pipe, nozzles 4 and 3 attached to discharge ports 22 and 23 at the tip of the nozzle pipe 1, and the like.
[0011]
First, the nozzle pipe will be described.
As shown in FIGS. 1 to 4, the nozzle pipe 1 has a water supply passage 2 formed therein, and has an inlet 21 on one side (rear side) and discharge ports 22 and 23 on the other side (front side). Is formed.
The nozzle pipe 1 is provided with one inflow port 21 and two discharge ports 22, 23, that is, the water supply passage 2 is formed in a bifurcated way, and the two discharge ports 22. -It is set as the structure which can discharge a chemical liquid etc. from 23.
The water supply passage 2 includes a long-distance water supply passage 24 formed substantially horizontally (in a straight line and on an axial center) from the inflow port 21, and a diagonally downward portion in the vicinity of the base of the long-distance water supply passage 24. A short-distance water supply passage 25 that is extended (bent into a "<" shape) is formed.
[0012]
A short-distance discharge port 23 is formed at the end of the short-distance water supply passage 25, and the short-distance nozzle 3 is attached to the short-distance discharge port 23. On the other hand, a long-distance discharge port 22 is formed at the end of the long-distance water supply passage 24, and the long-distance nozzle 4 is attached to the long-distance discharge port 22. Note that the short-distance discharge port 23 is disposed closer to the inflow port 21 than the long-distance discharge port 22.
Here, the long distance nozzle 4 sprays the liquid in a circle around the nozzle pipe 1, and the short distance nozzle 3 sprays the liquid between the long distance spraying range and the nozzle pipe. Thus, it is possible to perform watering evenly and uniformly within the watering range.
[0013]
A mounting portion 11 is formed on the nozzle pipe 1. The attachment portion 11 is formed on one side surface of the nozzle pipe 1 and is used when being fixed to the rotary water spray control machine. The mounting portion 11 is formed with fixing holes 11a and 11a for inserting bolts and the like.
In addition, the nozzle pipe 1 can be mounted on the rotation mechanism unit so that its vertical position can be changed.
[0014]
Next, the short distance nozzle 3 will be described.
As shown in FIG. 5, the short distance nozzle 3 includes an insertion portion 31 screwed into the short distance discharge port 23 and a nozzle portion 32 having a larger diameter than the insertion portion 31 and formed in a hexagonal shape. It is formed integrally.
A nozzle hole 33 is formed inside the short distance nozzle 3, an inlet 35 is formed on one side of the nozzle hole 33, and an outlet 34 is formed on the other side.
Further, a notch 32 a is formed at a part of the tip of the nozzle portion 32. The notch 32a is formed in a substantially fan shape when viewed from the front, and is formed from the discharge port 34 toward the rear side. That is, a notch 32a is formed in a substantially fan shape that gradually spreads in the radial direction from the discharge port 34 serving as an axial center and inclined from the end of the discharge port 34 to the oblique inlet side in a cross-sectional view.
[0015]
The discharge port 34 is formed with a substantially circular hole in the center portion when viewed from the front, and extends outward along the notch 32a from the hole.
Thus, by providing the notch 32a in the short-distance nozzle 3, the liquid to be discharged can travel straight (parallel to the axis) and in an oblique direction, and a short-distance control work and a water spray work can be performed. Can do.
In addition, the spray distance of the short distance nozzle 3 is the same as the spray distance of the long distance nozzle 4, and with such a configuration, the average spray amount in the spray range can be obtained, Watering can be performed uniformly.
[0016]
Next, the long distance nozzle 4 will be described.
As shown in FIGS. 1, 6, and 7, the long-distance nozzle 4 includes an insertion portion 41, a nozzle portion 42, and a breaker that are screwed into the long-distance discharge port 22.
A nozzle hole 43 is formed inside the long-distance nozzle 4, and an inlet 45 is formed on one side of the nozzle hole 43 and an outlet 44 is formed on the other side. The inflow port 45 is formed at the end of the insertion portion 41, and the discharge port 44 is formed at the end of the nozzle portion 42.
The nozzle hole 43 has a smaller diameter as it goes from the inflow port 45 to the discharge port 44, and can spray water at a long distance from the discharge port 44.
[0017]
The breaker includes a breaker arm 46, screws 48 having breaker pins 47 (FIG. 1), and the like. The breaker arm 46 is formed integrally with the nozzle portion 42 and is formed to protrude forward from the side portion of the nozzle portion 42.
At the end of the breaker arm 46, a screw hole 46a (FIG. 6) for mounting the breaker pin 47 is formed. A screw 48 having a breaker pin 47 formed at the tip is inserted into the screw hole 46a. At this time, a spring 49 is interposed between the screw head 48 a and the breaker arm 46 to prevent the screw 48 from loosening. Further, by changing the position of the screw 48, the amount of the water bundle to be crushed can be adjusted.
Thus, by providing a breaker in the long-distance nozzle 4, the water bundle is crushed so that water can be uniformly sprayed.
[0018]
Next, another embodiment of the long distance nozzle will be described.
The long-distance nozzle of another embodiment is configured such that the water bundle can be crushed and sprayed uniformly, as with the long-distance nozzle with a breaker. This will be specifically described below.
As shown in FIGS. 8 and 9, the long-distance nozzle 5 of another embodiment is formed with an insertion portion 51 screwed into the long-distance discharge port 22 and a hexagonal shape having a larger diameter than the insertion portion 51. The nozzle portion 52 is integrally formed.
The long-distance nozzle 5 has a discharge port 54 formed in the center of the front surface and an inflow port 55 formed in the rear surface. The discharge port 54 and the inflow port 55 communicate with each other through a nozzle hole 53. Yes.
The nozzle hole 53 is formed to have a smaller diameter as it goes from the inlet 55 to the outlet 54, and sprays water at a long distance from the outlet 54.
[0019]
A groove 56 is formed on the inner wall of the nozzle hole 53 from the end on the inlet 55 side to the end on the outlet 54 side. The groove 56 has the same depth on the inflow port 55 side and the discharge port 54 side, and the groove 56 is formed in an arc shape when viewed from the front. That is, the cylindrical groove 56 slightly smaller than the diameter of the discharge port 54 is parallel to the upper oblique side of the conical nozzle hole 53 opened inside the long-distance nozzle 5, and the axis is on the left and right sides (left side). Drilled eccentrically.
Thus, by forming the groove 56 in the nozzle hole 53, the nozzle hole 53 is formed so that the discharge port 54 is smaller than the inflow port 55. Since the inlet 55 is formed with the same diameter, the flow rate of the liquid passing through the groove 56 toward the discharge port 54 is slower than the flow rate of the liquid passing through the nozzle hole 53 toward the discharge port 54. Therefore, liquids with different flow velocities sprinkle outside while colliding in the vicinity of the discharge port 54, so that the water bundle can be crushed and the water can be sprayed uniformly as in the case of using a breaker.
In this way, by forming the groove 56 in the nozzle hole 53, the water bundle can be crushed and sprayed evenly without installing a breaker, and the cost can be reduced.
[0020]
Next, the usage pattern of the nozzle structure will be described.

At this time, when the nozzle pipe 1 is mounted on the rotation mechanism 61 so that the short-distance nozzle 3 is located at the upper part and the long-distance nozzle 4 is located at the lower part, the breaker pin 47 is disposed upward and is directed upward. Since water is sprayed, grape leaves can be disinfected as shown in FIG.
[0021]
Further, as shown in FIG. 10B, when watering the field below the vine shelf, the nozzle pipe 1 is changed in its vertical position with respect to the rotation mechanism portion 61 (the longitudinal direction of the nozzle pipe 1). ), The short distance nozzle 3 is arranged at the bottom and the long distance nozzle 4 is arranged at the top to water the vineyard.
As described above, the discharge ports 22 and 23 are provided in the upper and lower portions of the nozzle pipe 1, the long-distance nozzle 4 is attached to the upper discharge port 22, and the short-distance nozzle 3 is attached to the lower discharge port 23. In the spraying range, there is no uneven spraying and watering can be performed evenly.
Moreover, since the said nozzle pipe 1 is mounted | worn so that the up-and-down position can be changed with respect to the rotation mechanism part 61, the attachment direction of the nozzle pipe 1 can be changed and the watering direction can be changed according to the objective. .
