b, and a base pipe 15 is screwed into the insertion hole 11b via a connecting member 15a. In this manner, the sprinkler 14 is arranged as close to the first axis P as possible, so that the moment when the swing case D swings is reduced.

As shown in FIGS. 11 to 13, a shaft 41a at the lower part of the main body 41 is rotatably fitted on the base pipe 15, and a spring 42 is interposed on the shaft 41a.
This spring pressure urges the main body 41 at a constant pressure so as not to rotate. A nozzle 16 capable of discharging laterally at a predetermined discharge angle is disposed in the middle of the main body 41. Further, a gate-shaped support portion 40 is provided on the upper part of the main body 41, a pivot shaft 41c is provided at the center of the support portion 41, and a reaction arm 43 is rotatably supported on the pivot shaft 41c. 43 is urged to rotate toward the nozzle 16 by a spring 47 fitted on the outer periphery thereof, and is stopped by the support portion 40. One end of the reaction arm 43 is extended to the outlet of the nozzle 16 and provided with a guide portion 43a which takes in a part of the liquid to be discharged and guides it as shown by an arrow G in FIG.

The other end is inserted between the pins 50a and 50b,
3c is extended to a length in contact with 3c. As shown in FIGS. 13 and 14, a lever arm 49 is further pivotally supported on the pivot shaft 48, and a regulating rod 49a at one end of the lever arm 49 is inserted between the rotation regulating pins 50a and 50b. A switching lever 45 is rotatably attached to the side of the lever arm 49 and protrudes downward.
A rod 51 is pivotally supported at the other end of the rod 9, the other side of the rod 51 is slidably inserted into the regulating body 44, and a spring 52 is fitted between the regulating bodies 44 on the rod 51. I have.

On the shaft portion 41a of the main body 41 of the sprinkler 14, stoppers 53a and 53b for controlling the rotation angle of the sprinkler 14 about the second axis Q of the sprinkler 14 are fitted. As shown in FIG.
The switching lever 45 is configured to rotate between the stoppers 53a and 53b.
The rotation of the sprinkler 14 is switched by abutting on the rotation of the sprinkler 53b. Therefore, the rotation angle of the sprinkler 14 is controlled by the stoppers 53a and 53b.

Then, as shown in FIG. 2, the sprinkler 1
A plate 79 shown in FIG. 15 is attached on a plane on which the four cases of the sprinklers 14 are attached. The plate 79 serves as a guide for the adjustment position of the stoppers 53a and 53b. When the stoppers 53a and 53b are rotated in accordance with the plate 79, the rotation angle of the sprinkler 14 can be adjusted. By providing the plate 79 as a guide for the positions of the stoppers 53a and 53b as described above, the rotation angle of the sprinkler 14 can be easily adjusted, and the spraying range can be known without performing test spraying.

In such a configuration, FIGS.
As shown in FIG. 4, when the switching lever 45 is at the J position (FIG. 14), a part of the liquid discharged from the nozzle 16 is
a, the reaction pressure of the reaction arm 43
7 in the direction of arrow M (FIG. 11). In this position, the position is not hit by the water discharged from the nozzle 16, so that the main body 41 is rotated back to the original position by the force of the spring 47, and the reaction arm 43 hits the support portion 40 and the main body 41 is moved in the N direction (see FIG. Rotate to 11). At this time, the main body 41 is braked by the spring 42 fitted to the shaft portion 41a and can rotate stably. Then, since the guide portion 43a returns to the original position, the guide portion 43a is again rotated in the M direction by the water discharge pressure. This operation is repeated, and the main body 41 is gradually rotated.

As described above, the main body 41 of the sprinkler 14 is rotated, and the switching lever 45 is moved to the stoppers 53a and 53a.
When the lever arm 49 is rotated by contacting the lever 3b, the lever arm 49 contacts the rotation regulating pin 50a, and the switching lever 45 stops at the K position (FIG. 14). At this time, the regulating rod 49b is pivoted downward, the rod 51 is beyond the dead center, the regulating body 44 is pivoted upward by the urging force of the spring 52, and the regulating plate 44a at the other end is pivoted downward. Then, it comes into contact with the rotation regulating pin 50b and stops. When the regulating body 44 pivots upward in this manner, the contact portion 43c of the reaction arm 43 comes into contact with the regulation body 44, and the reaction arm 43 cannot rotate in the M direction due to water discharge. The rotating force in the M direction can rotate the main body 41 in the M direction and rotate the sprinkler 14 in the opposite direction. When the switching lever 45 comes into contact with the stoppers 53a and 53b and is rotated from the K position to the J position, the regulating body 44 is lowered, and the sprinkler 14 rotates in the N direction. In this way, the reciprocating rotation is repeated.

The rotation angle θ (FIG. 2) of the sprinkler 14 that rotates about the second axis Q that is substantially parallel to the ground by the above-described mechanism is such that the nozzle 16 of the sprinkler 14 is substantially vertical. In addition, it is configured to rotate between substantially right angles between substantially horizontal. Therefore, the stoppers 53a
The control of the rotation angle θ of the sprinkler 14 by adjusting the position of the position 53b is effective in a substantially vertical or substantially horizontal direction.

Since the sprinkler 14 according to the present invention has a rotation angle θ that is approximately half that of the conventional sprinkler 14 that rotates at a substantially flat angle from substantially horizontal to substantially horizontal, the pitch of the reciprocating rotation movement is Is reduced and dense spraying becomes possible. As an example of the spraying state of the sprinkler 14 according to the present invention, the rotation angle θ of the sprinkler 14 is set to 20 ° to 75 ° with a substantially right angle of 0 ° in FIG. 16 and adjusted so as to reciprocate between these angles. The scattering state in a plan view of the discharged chemical solution when the swing case D is rotated all around the circumference (3.
6).

As can be seen from the scattering state (36),
The chemical tends to concentrate at the center where the oscillating sprinkler 1 is located. Therefore, in order to avoid concentration of the chemical solution, FIG.
As shown in FIG. 4, a breaker 39 is provided at the upper end of the swing sprinkler 1. As shown in FIG. 16, the breaker 39 has a comb shape and is fixed to one end of a breaker arm 39a, and the breaker arm 39a is fixed to an upper end of the main body of the swing sprinkler 1. Then, at the time of spraying the chemical solution, when the nozzle 16 is at the highest position,
When the position is adjusted so as to be located above the nozzle 16 and the chemical liquid hits the breaker 39 from below, there is an effect of dispersing the chemical liquid. Further, by providing the breaker 39, the chemical liquid is dispersed, so that the chemical liquid is also scattered to the medicine application object located above without rotating the nozzle 16 almost to the level.

The oscillating water spray control device 1 is also used for watering work, but it is not necessary to scatter water to the upper part during the watering work. Is washed away. Therefore, during the sprinkling operation, the following prevention / sprinkling switching mechanism is configured so that the angle of the nozzle 16 is fixed and only the swing case D can be switched so as to swing about the first axis P. ing.

As shown in FIG. 13 and FIG.
A substantially gate-shaped stopper 46 is rotatably provided at the distal end portion 16a of the nozzle 16. By rotating the stopper 46, the nozzle 16 rotates around the second axis Q and rotates. It can be switched to a state where it is not performed.

When performing the control work for spraying the chemical, the stopper 46 is adjusted to the position S shown in FIG. 13, and at this time, the reaction arm 43 is moved to the position (Sa) where the chemical discharged from the nozzle 16 comes into contact. There is a recoil arm 4
Reference numeral 3 rotates by the discharge pressure of the chemical solution, and the sprinkler 14 rotates about the second axis Q by the above-described sprinkler rotation mechanism. Since the sprinkler 14 rotates about the second axis Q in the horizontal direction and the swing case D swings about the first axis P in the vertical direction, the liquid medicine is sprayed. is there.

On the other hand, when performing the watering work, the stopper 46 is rotated to the position T shown in FIG. At this time, the reaction arm 43 is fixed to a position (Ta) where the water does not hit by the stopper 46. Therefore, the reaction arm 4
The sprinkler 14 does not rotate because the water discharged from the nozzle 16 does not hit 3. And nozzle 1
Numeral 6 is fixed to a fixed position, and the water sprinkling operation is performed in a state where the swing case D swings around the first axis in the vertical direction, so that the discharged water swings while maintaining a certain height. A radial trajectory is drawn around the dynamic water spray control device 1. As described above, sprinklers 14 suitable for watering work and controlling work
The switching mechanism for controlling watering and spraying for setting the rotation state of the water spraying is constituted, and the switching mechanism for watering and spraying prevention has a simple structure and operates reliably, so that the cost associated therewith can be reduced.

As described above, the swing sprinkler 1 according to the present invention has the swing case D, which is the main body of the swing sprinkler 1, substantially at the center of the swing case D and perpendicular to the ground. The sprinkler 14 of the oscillating sprinkler 1 is substantially perpendicular to the first axis P and substantially at the center of the main body of the sprinkler 14. Is rotated about the second axis Q, which not only can control the horizontal spray range of the chemical solution or water sprayed from the sprinkler 14, but also can control the height direction. Therefore, compared with the conventional rocking and spraying apparatus that rotates around an axis parallel to the ground, the amount of the chemical solution that hits the ground can be reduced, and waste of the chemical solution can be prevented. . Since the discharged chemical reaches the high position compared to the conventional machine, it is convenient particularly when the chemical is sprayed on the drug to be administered at the high position in the orchard.

As described above, the present invention has the following advantages.

That is, according to the first aspect of the present invention, in the oscillating sprinkler comprising an oscillating case and a discharge member, the oscillating case is disposed on the bearing case, and the discharge member is disposed on the oscillating case. Then, the swing case is swingably supported about a substantially vertical axis, and the swing case is configured to swing using the water discharge water flowing into the swing case. Since the vertical spraying range of the chemical solution or water to be sprayed can be controlled, it is possible to spray water in accordance with the height range of the crop to be cultivated. This can increase the efficiency of watering work.

According to a second aspect of the present invention, in the above-mentioned oscillating water sprinkler, a discharge body having a rotation axis in a direction substantially perpendicular to an axis in a direction substantially perpendicular to the oscillating case is disposed. Since it is possible to set an appropriate vertical discharge angle according to the work content such as work and watering work, it is possible to spray water according to the height range of the crop to be cultivated,
By changing the discharge angle in the vertical direction, the reach distance can also be changed, so without discharging water to the ground,
It is possible to prevent the chemical solution from being lost in the control work, and to improve the efficiency of the watering work.

According to a third aspect of the present invention, the nozzle of the discharge body is configured to rotate at a substantially right angle from substantially horizontal to substantially vertical. Therefore, in the control operation, the chemical solution can be more densely sprayed, and the occurrence of uneven spraying can be prevented.
