L · 10R pivoting case D (gear case 12
And the sprinkler case 11) rotates about the first axis P.

Then, by turning upward or downward,
When pivoting to the end of the set range, the contact portion 25b of the valve arm 25 contacts the cam 26, the contact portion 25a is pivoted, the switching valve 24 is pivoted, and the water flow pipe 22F (22R). The empty suction port 22Fb (22Rb) is closed, the other suction port 22Rb (22Fb) is opened, and water is discharged from the other discharge port 80Ra (80Fa) to face the opposite surface of the blade of the water wheel 23. To rotate the water wheel 23 in the reverse direction. By this reverse rotation, the swing case D is rotated in the opposite direction about the first axis P. In this way, the valve is switched at the end of the set range to change the rotation direction and reciprocate.

As shown in FIGS. 14, 15 and 16, a relief valve 35 is provided on the gear case lid 21. The relief valve 35 has a through hole 21a opened in the gear case lid 21. The periphery of the through hole 21a on the side of the water supply chamber C is formed in a valve seat, and the valve shaft 35a is inserted and urged by a spring 35c so that the valve body 35b is seated on the valve seat and closed. Then, the operating shaft 36 is inserted from the side surface of the gear case 12, and a pressing cam 37 is fixedly provided in the pressure chamber A at the distal end of the operating shaft 36, and is disposed so as to be in contact with the distal end of the valve shaft 35 a. A lever 38 is fixedly mounted on the operating shaft 36, and by rotating the lever 38, a pressing position at which the pressing cam 37 presses the valve shaft 35a,
It is possible to change the operating position where no pressing is performed.

In such a configuration, when the pressing cam 37 is in the operating position away from the valve shaft 35a, the relief valve 35 maintains the pressure chamber A at the set pressure, and pressurized water is supplied from the discharge port 22Fa or 22Ra. The water turbine 23 is rotated by discharging the water, the rocking case D is rocked, and when a water pressure higher than a set pressure is generated due to an abnormality of a pump, a water hammer or the like, the valve body 35b is pushed and opened by the water pressure. Thus, the water flows directly from the pressure chamber A to the water supply chamber C to prevent damage due to pressure. When the water supply is stopped in this state, a large force is required by the speed reduction mechanism 9 built in the swing case D in order to rotate the swing case D with respect to the bearing case 10R.

When the swinging is stopped and the sprinkling operation is performed, the lever 38 is rotated by approximately 180 ° to maintain the pressing cam 37 at the position where the pressing cam 37 is pressed against the valve shaft 35a. 35 is forcibly opened to eliminate the pressure difference between the pressure chamber A and the water supply chamber C, thereby preventing the water wheel 23 from rotating without discharging from the discharge port 22Fa or 22Ra. That is, the swing can be released by the rotation of the lever 38.

At the time of sprinkling, the sprinkler 14
Since it is rotated by 0 °, in an inclined state other than vertical, the water is discharged toward the ground at the lower sprinkling position, and is wasted. Therefore, the second axis Q which is the rotation axis of the sprinkler 14 is substantially It must be vertical so that water can be sprinkled in the horizontal plane. However, the bearing case 10L
When the sprinkler 14 is stopped at a position where the second axis Q is not perpendicular to the support state at the time of control when 10R is supported by the stand 13, the second axis Q is substantially perpendicular from this position. To rotate to a certain position, a large force is required as described above. However, when the support pins 13b of the stand 13 are withdrawn from the control support holes 55b, the swing case D is rotatably supported by the through holes 10a of the bearing case 10L. The swing case D can be easily rotated to a position where is substantially vertical without applying force.

Therefore, the support pins 13b of the stand 13
13b is removed from the control support holes 55b and 55b,
The swing case D supported by the bearing case 10L is made rotatable with respect to the bearing case 10L, the stand 13 is shifted to the left, and the support pins 13b and 13b are sprayed on the swing case D. The bearing case 10L is rotated with respect to the swing case D so as to match the positions of the support holes 12f and 12f, and the support pins 13b and 13b are sprinkled with the watering support holes 12f and 12f.
It fits into f. Watering support holes 12f
Since the second axis Q of the sprinkler 14 is located vertically with the support pins 13b of the stand 13 fitted, the portable swing water sprinkler 1
Is supported by the stand 13 with the second axis Q of the sprinkler 14 fixed vertically.

As described above, the portable oscillating sprinkler 1 is supported by the stand 13 so as to be switched between the control state and the sprinkling state. For example, the second shaft center of the sprinkler 14 at the end of the control. Even if Q was not positioned vertically, it was possible to easily switch to the sprinkling state without applying force and to greatly improve operability.
Further, since the support pin 13a is fitted into the common support hole 10d, the stand is less likely to fall off from the portable oscillating water sprinkler 1 during the switching operation, thereby improving workability.

Further, on the upper part of the sprinkler case 11,
Forming a plane for mounting the sprinkler 14,
An insertion hole 11b communicating with the water supply chamber C is opened at the center of this plane, and a base pipe 15 is screwed into the insertion hole 11b. In this way, the sprinkler 14 is arranged as close to the first axis P as possible, so that the moment of vertical swing is reduced.

On the other hand, below the sprinkler case 11,
A recess 11a is formed, and a drain hole 58 is opened on the right side surface of the recess 11a. The drain hole 58 is configured to be opened and closed by a drain valve 59. In a normal use state, FIG.
As shown in FIG. 7, a drain valve 59 is openably and closably fitted in a drain hole 58 communicating the water supply chamber C and the concave portion 11a.
The periphery of the water supply chamber C side of 8 is formed in a valve seat, and the drain valve 59 is urged by a spring 60 so that the valve body 59b is seated on the valve seat and the drain valve 59 is closed. And after work such as control and watering is completed,
When the valve shaft 59a of the water drain valve 59 is pressed to open the water drain hole 58, the chemical solution, water, and the like remaining in the water supply chamber C can be discharged from the water drain hole 58. Accordingly, it is possible to prevent the chemical solution remaining in the water supply chamber C and impurities contained in the water from sedimenting like a sludge, thereby preventing the movement of the driving unit such as the water wheel 23 from being hindered.

Next, the structure of the sprinkler 14 is shown in FIG.
8 and FIG. A shaft 41a at the lower part of the main body 41 is rotatably fitted on the base pipe 15, and the shaft 41
a spring 42 is interposed on the main body 4.
1 is urged at a constant pressure so as not to rotate. A nozzle 16 is disposed in the middle of the main body 41 so as to be discharged to the side at a set angle above a horizontal plane.

A gate-shaped support portion 4 is provided on the upper part of the main body 41.
1b, a pivotal shaft 41c coinciding with the second axis Q is provided at the center of the support portion 41, and a reaction arm 43 is rotatably supported on the pivotal shaft 41c. It is urged to rotate toward the nozzle 16 by a spring 47 fitted on the outer periphery, and is stopped by the support portion 41b. One end of the reaction arm 43 is extended to the outlet of the nozzle 16 and provided with a guide portion 43a for taking in a part of the liquid to be discharged and guiding it as shown by an arrow G in FIG.
4, the weight 43b is fixed, and a contact portion 43c is formed below the weight 43b.

The restricting body 44 is pivotally supported by a pivot 48 projecting from the side of the main body 41, and a restricting plate 44a at one end (right side in FIG. 18) of the restricting body 44 is a rotation restricting member protruding from the side of the main body. The other end is inserted between the pins 50U and 50D.
3c extends downward. A lever arm 49 is further pivotally supported on the pivot shaft 48. A regulating rod 49a at one end of the lever arm 49 is inserted between the rotation regulating pins 50U and 50D. Switching lever 45
Is rotatably mounted and protruded downward, and pivotally supports a rod 51 at the other end of the lever arm 49.
The other side is slidably inserted into the regulating body 44, and a spring 52 is fitted between the regulating bodies 44 on the rod 51.

A cam for setting a rotation angle is disposed on the upper surface of the flat portion of the sprinkler case 11 on the rotation trajectory of the switching lever 45 about the second axis Q. This cam is fixed at a position where the switching lever 45 abuts on a plane on the sprinkler case 11 on the same circumference around the axis Q and sets the rotation angle of the sprinkler 14. A long hole is opened in this cam and fixed by screws, and the rotation angle can be changed by changing the fixing position of the long hole. By providing this cam on the side of the sprinkler case 11, the height of the sprinkler 14 can be suppressed to be close to the first axis P, and the inertia moment due to the weight of the sprinkler 14 itself and the reaction force due to discharge can be reduced. I have.

In such a configuration, the switching lever 45
Is in the J position (FIG. 18), a part of the liquid discharged from the nozzle 16 hits the guide portion 43a, and the water pressure causes the reaction arm 43 to oppose the spring 47 in the direction of arrow M (4).
3 '). In this position, since the position is not hit by the water discharged from the nozzle 16, 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 41b and the main body 41 is moved in the N direction by its inertia force. To rotate. At this time, the main body 41 can be stably rotated by being braked by the spring 42 fitted to the shaft portion 41a. 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 rightward.

When the switching lever 45 is rotated in such a manner as to come into contact with the cam 46, the lever arm 49 comes into contact with the rotation restricting pin 50U, and the switching lever 45 stops at the K position. At this time, the regulating rod 49b is pivoted downward so that the rod 51 exceeds the dead center, and the urging force of the spring 52 causes the regulating body 44 to pivot upward and the regulating plate 44 at the other end.
a is rotated downward, abuts against the rotation restricting pin 50D, 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 cam 46 and is rotated from the K position to the J position, the regulating body 44 is rotated.
Is lowered, and the sprinkler 14 rotates in the N direction. Thus, the reciprocating rotation is repeated.

When the switching lever 45 is rotated to the H position, the switching lever 45 cannot contact the cam 46 and rotates only in the same direction so that it does not reverse. This state is the watering position, and as described above, 3
