BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate an example of the preferred embodiment of the present invention.
Tapered hole 62 that spreads slightly upward from the upper part of the inner peripheral surface of the cylinder
The sprinkler board 3 having the female tapered hole and the engaging portion that engages with the inner peripheral surface of the cylinder is removably fitted to the opening 2, and a plurality of sprinkler sections 10 are provided on the upper surface of the sprinkler board 3. A lock receiving portion 40 is provided below the center hole 4 provided in the center portion of the water sprinkling board 3, and a locking head 41 to be locked to the locking receiving portion 40 is attached to the center hole of the water sprinkling board 3. The valve head 5 is provided on the upper part of the valve cylinder 5 to be fitted into the cylinder 4, and the locking head 41 is engaged with the locking receiving part 40, and the valve cylinder 5 is fixed to the watering nozzle body 1 side by an appropriate fixing means 32. In the illustrated embodiment, a female screw hole 7 'is provided in a water passage portion 7 provided near the lower portion of the partition wall 6 of the watering nozzle body 1, and a male screw portion 5 provided at the lower end of the valve cylinder 5 is provided in the female screw hole 7'. 'To form the fastening means 32.

The valve cylinder 5 is inserted into the female screw hole 7 of the watering nozzle body 1.
The male screw hole 5 ′ is screwed into the water sprinkling nozzle body 1 so that the upper inner peripheral surface 4 ′ of the center hole 4 of the water sprinkling board 3 is exposed when the valve case 5 is fixed to the water sprinkling nozzle body 1. A concave groove 60 is provided in the upper inner peripheral surface 4 ′ of the center hole 4 of the board 3, and an external expansion type snap ring 61 abutting on the upper surface of the locking head 41 of the valve cylinder 5 is fitted into the concave groove 60. The valve cylinder 5 is fixed in a retaining state.

A square hole 14 is formed in the upper part of the valve cylinder 5, and a step is provided in the square hole 14 so that the female screw part 5 ″ having a smaller diameter than the square hole 14 is formed.
And a valve body 9 that is screwed into the female screw portion 5 ″ to open and close the valve hole 8. A rubber sleeve-shaped water pipe connection portion 11 is provided below the watering nozzle body 1.

At a plurality of locations on the inner peripheral surface of the water guide cavity 71 provided around the valve cylinder 5, water sprinkling plate support projecting walls 72 for supporting the lower surface 3 'of the water sprinkling plate 3 are provided. The sprinkling plate support projecting wall 72 radially protrudes toward the valve cylinder 5. At this time, if the projecting angles are all inclined in the same direction and deviate slightly from the direction toward the center, the flowing water swirls in a spiral shape to sprinkle water. To be good.

[0015] The nozzle unit 1 0 you drilled perpendicularly against the recess 73 a recess 73 provided on the inner surface to the nozzle plate 3.

Since the embodiment of the present invention is constructed as described above, when removing the watering board 3 from the watering nozzle body 1,
When a turning tool is inserted into the square hole 14 on the upper part of the valve cylinder 5 and the male screw portion 5 'of the fastening means 32 is turned in the loosening direction, the screw action with the female screw hole 7' of the watering nozzle body 1 is performed. The valve cylinder 5 rises and is locked by the locking receiving portion 40 of the water sprinkling board 3 and the concave groove of the water sprinkling pipe 3
The valve cylinder 5 fixed in the retaining state by the snap ring 61 of the sprinkler 60 can be lifted up from the sprinkler nozzle body 1 integrally with the sprinkler board 3 and removed, so that the sprinkler 10 of the sprinkler board 3 can be removed. Correction of clogging and cleaning and repair of the inside of the watering nozzle body 1 can be easily performed.

Further, a sprinkler plate 3 provided above the sprinkler nozzle
Is frequently loaded with automobiles and is easily damaged. At this time, according to the present invention, since the lower surface 3 'of the water sprinkler 3 is supported by the water sprinkler supporting wall 72 projecting from several places on the inner peripheral surface of the water guide cavity 71, the water sprinkler 3 is reinforced and a durable water sprinkler which is not damaged is provided. It becomes a nozzle.

Reference numeral 15 in the figure prevents dust from the watering surface from entering the watering nozzle body 1, prevents water from oozing from the inside of the watering nozzle body 1 onto the watering surface, and facilitates removal. If the opening edge is formed in the tapered hole 62 of the upward expansion type with the O-ring which also serves as a function, it becomes easier to come off. Sign 1
6 and 17 are O-rings, and 18 is a rubber stopper for protecting the valve cylinder 5 and the valve body 9.

[0019]

According to the present invention constructed as described above, the sprinkler can be easily removed from the sprinkler nozzle body, so that the clogging of the sprinkler board can be corrected and the inside of the sprinkler nozzle body can be cleaned and repaired. It is easily possible.

In addition, the watering nozzle is excellent in practicality and does not damage the watering board due to the load of the vehicle on which the vehicle rides.
