DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a watering vehicle suitable for use in a golf course. That is, as shown in FIGS. 1 to 3, the wheels 11 and 12 before and after supporting the vehicle body 1 are formed of a wide elastic body that is wide in the width direction of the vehicle body 1 such as a foamed synthetic resin such as urethane foam. I have. By forming the front and rear wheels with a wide elastic body as described above, when the watering vehicle runs on the grass peculiar to the golf course, the locus of the wheels remains, that is, a rut (groove) is generated as much as possible. Can be prevented.

At the rear of the vehicle body 1, a watering tank 6 is mounted, to which a watering pump 13 and a water pipe 14 guided to the outside by the pump are connected, and the upper hose 4 and the lower hose 4 are connected to the water pipe 14. 5 is branched and connected.

At the rear of the watering tank 6, a support casing 8 for watering is attached.
The casing 8 is supported by a front support stay 9 and a rear support stay 10 so that the direction of the casing 8 about the pivot 16 can be adjusted vertically from the horizontal direction. That is, the front support stay 9 is composed of a support piece 9a, a support sheath 9b in which the support piece 9a is fitted, and a lever 9c for fixing the both, and the rear support stay 10 is further fixed by using the watering tank 6. The front support stay 9 is provided as described above.
When the fitting position between the support piece 9a and the support sheath 9b is fixed by the lever 9c, the lever 1 of the rear support stay 10 is simultaneously
The support casing 8 pivotally connected to the pivot 16 by Oa can be fixed horizontally or slightly upward or downward.

As shown in FIGS. 4 to 6, the support casing 8 has a substantially fan-shaped plan shape (FIG. 6), and has an opening 17 at its rear side, that is, toward the rear of the vehicle body 1.
Are formed (FIGS. 4 and 5). The oscillating nozzle case 2 inside the supporting casing 8 also has a fan-shaped planar shape, and the oscillating nozzle case 2 through which water for spraying flows circulates.
It is attached so that it can swing horizontally around the center. The swinging nozzle case 2 is provided with the nozzle 3 projecting rearward from the opening 17 of the support casing 8.

More precisely, the oscillating nozzle case 2 mounted inside the support casing 8 via a bearing 19 is an upper oscillating nozzle case 2A supported on an oscillating support shaft 18A.
And a lower oscillating nozzle case 2B also supported by the oscillating support shaft 18B, and the nozzles 3A, 3B
Is attached. Upper swing nozzle case 2A
The upper hose 4 is connected to its upper surface, and the lower hose 5 is connected to its lower surface in the lower swinging nozzle case 2B.

A cover casing 20 is fixed to the front surface of the support casing 8, a motor 22 is fixed to the support casing 8 via the cover casing 20 and the support bracket 21, and the motor 22 is eccentric to its rotation shaft 22a from its rotation center by t. The eccentric shaft 23 is integrally formed with the upper oscillating rod 24A and the lower oscillating rod 24B.
Are coaxially pivotally connected, and the upper swing rod 24A is
As shown in FIG. 5, the lower swing rod 24B is pivotally attached to the lower swing nozzle case 2B at a position closer to the left in the figure, and the lower swing rod 24B is located at a position closer to the right in the figure.

Accordingly, the upper oscillating nozzle case 2A pivotally connected to the upper oscillating rod 24A by the rotation of the eccentric shaft 23 by the driving of the motor 22, and the lower oscillating rod 24
The lower oscillating nozzle case 2B pivotally connected to B is reciprocally oscillated right and left about the oscillating support shaft 18 as a fulcrum, as shown by arrows in FIG. If the motor 22 can change the speed, the swing speed of the nozzle 3
It is also possible to adjust to an optimum state in consideration of the diameter of A, 3B or the flow velocity.

Although the present invention has the above-described structure, when using the same, the sprinkler 13 and the motor 22 are driven while the sprinkler is running on the golf course, so that the chemical solution in the sprinkler tank 6 can be used. The water is branched into an upper hose 4 and a lower hose 5 through a water pipe 14 and sent out to an upper oscillating nozzle case 2A and a lower oscillating nozzle case 2B.
Water will be sprayed from A and 3B.

During the sprinkling, the upper and lower oscillating nozzle cases 2A and 2B are swung right and left in a substantially horizontal plane. As shown in FIG. 7, the water droplets w are spouted in a meandering manner when viewed macroscopically, which makes it possible to sprinkle water evenly on the surface to be sprinkled and to spray water. Nozzles 3A and 3B to prevent
The upper and lower swing nozzle cases 2A, 2B are swung right and left even if the diameter of the water droplets is increased by increasing the diameter of the nozzle, so that the water sprayed from the nozzles 3A, 3B on the rear surface is not shown in FIG. As shown in FIG. 7, water can be sprayed evenly and sufficiently on the surface to be sprayed.

The upper and lower oscillating nozzle cases 2
Since the open / close cock 7 is provided on one side of the upper and lower side hoses 4 and 5 connected to A and 2B, the flow of one hose 5 is cut off by the open / close cock 7 according to the situation of the watering site. For example, the amount of water spray can be adjusted by spraying water only from the nozzle 3A of the other upper swing nozzle case 2A.

Further, since the upper and lower oscillating nozzle cases 2A, 2B are formed so as to be vertically adjustable via the support casing 8 and the front and rear support stays 9, 10, the upper and lower oscillating nozzle cases 2A, 2A, 2B nozzle 3A,
The direction of 3B can be adjusted upward or downward according to the conditions of the watering site.

In FIG. 1, reference numeral 25 denotes a watering tank 6.
, 26 is a driver's seat, and 27 is a steering wheel.

[0022]

According to the first aspect of the present invention, when water is sprayed, the oscillating nozzle case is swung right and left in a substantially horizontal plane. Macroscopically, water droplets are ejected in a meandering shape, which makes it possible to spray water evenly on the surface to be sprayed and to prevent the nozzle from being sprayed in a spray shape. Even if the water droplets to be sprayed are enlarged by increasing the size, the upper and lower oscillating nozzle cases are swung to the left and right. You can sprinkle enough.

According to the second aspect of the present invention, the upper oscillating nozzle case and the lower oscillating nozzle case can reciprocally oscillate right and left alternately and independently of each other. Water can be finely and evenly sprayed.

According to the third aspect of the present invention, depending on the situation of the watering site, the open / close cock cuts off the flow state of one hose and water is sprayed only from the nozzle of the other swinging nozzle case. The amount of watering can also be adjusted.

According to the fourth aspect of the present invention, the direction of the nozzle of the upper and lower swinging nozzle case can be adjusted upward or downward in accordance with the conditions of the watering site.
