is inserted into the lower pipe body 14 from above, and the third female thread 13 and the third male thread 20 are screwed together, and both ends of the water control piece 22 are opened inwardly and outwardly in the peripheral wall 23 of the water control piece 22. A movable hole 24 is opened, and the second embodiment shown in FIG. Since the configuration is almost the same as that of the embodiment, the same reference numerals will be used and detailed explanation thereof will be omitted.

In the figure, 25 is a water supply pipe, 26 is a hexagonal hole for fitting a hexagonal wrench, and 27 is a rubber stuffing lid.

(Function) Since the present invention has the above-mentioned configuration, by raising or lowering the water control piece 22, the height of the movable water guide hole 24 and the height of the fixed water guide hole 15 are made the same, that is, a large amount of water flows out. When it is in the possible state, when the water control piece 22 is twisted by a slight angle and the movable water guide hole 24 and the fixed water guide hole 15 are placed in a position where they do not overlap, a fully closed state can be obtained. I can do it,
Further, when the positions match, a fully open state can be obtained. Furthermore, even when the water control piece 22 is in a state where it is at a half-height position, that is, a state where a small amount can flow out, a partially open state can be obtained by opening and closing the water control piece 22. In addition, by increasing or decreasing the above-mentioned weight of a portion of the water guiding movable hole 24 and the water guiding fixed hole 15, the opening degree of the partial opening can be controlled by water pressure (flow rate).
It can be finely adjusted according to changes in

Further, FIG. 5 shows a case where the extension tube 3 is removed and used, and in this case, the lower tube body 14 is shortened by the height of the extension tube 3.

(Effect of the invention) Since the water spray nozzle device for road snow removal according to the invention has the above-mentioned configuration, for example, when it is desired to raise the road surface during road repair, the extension pipe 3 and the pipe body 28 can be made longer. It is a case that can be replaced with the existing case 1, which is fixed to the water supply pipe 25 and hardened with cement, asphalt, etc.
It is of course effective that repairs can be made without tampering with the water control piece 22, and in particular, the construction allows the water control piece 22 to be raised and lowered by screwing the third female screw 13 and the third male screw 20. Therefore, it can be opened and closed to allow a large amount to flow out, or to allow a small amount to flow out, and to open and close to allow a large amount to flow out, or to open and close to a state that allows a small amount to flow out. It is extremely easy to use, and by increasing or decreasing the above-mentioned weight of a portion of the water guide movable hole 24 and the water guide fixed hole 15, the degree of partial opening can be adjusted to changes in water pressure (flow rate). It has the advantage of being able to be finely adjusted, and has great practical effects.
