Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sprinkler, and particularly to a self-propelled sprinkler.

[Conventional technology and its problems]

All sprinklers used in parks or golf courses are stationary, so a large number of sprinklers are installed to match the water removal radius, but they are moved at regular intervals to ensure that water is removed from all areas that require water removal. However, in the former case, it is necessary to install many sprinklers, and when piping is included, it becomes a huge economic burden. Moreover, in the latter case, manpower is required to move the sprinkler, which is undesirable from the viewpoint of labor saving.

On the other hand, in gardening such as greenhouses, raising livestock, etc., there are systems in which sprinklers can be run using electric motors.

Although this traveling type sprinkler may be installed in the above-mentioned parks and golf courses, it requires a power lead wire, which increases the cost and is not aesthetically pleasing.

[Purpose of invention]

The present invention aims to solve the above problems by causing the sprinkler to run using the pressure of the water sent to the sprinkler.

[Means to solve the purpose]

In order to achieve the above object, the sprinkler of the present invention is provided with a water pressure motor and a sprinkler on a truck, and a water supply pipe is connected to the water inlet of the water pressure motor, and the head of the sprinkler is connected to the water outlet through a water conduit pipe. The drive shaft of the hydraulic motor extends to the axle of the truck, and the rotation of the drive shaft is transmitted to the axle by a transmission means, and the wheels are mounted on the axle.

[Effect]

In the sprinkler of the present invention constructed as described above, the water pressure motor is driven by the pressure of the withdrawn water, and the rotation of the drive shaft of the motor is transmitted by the transmission means to rotate the axle, and the sprinkler is attached to the axle. The trolley carrying the sprinkler runs on the wheels and drains water evenly over a wide area.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a truck, and this truck 1 is provided with a bearing 2, and an axle 3 is fixed to the bearing 2 through the axle 3.
Wheels 4 are fitted at both ends.

A base 6 with a built-in hydraulic motor 5 is fixed to the cart 1 by bolts 7, a water supply pipe 9 is connected to a water inlet 8 of the hydraulic motor 5, and a water conduit pipe 11 extends to a drain port 10. There is an opening 13 in the top sprinkler mounting screw 12 of the base 6.

A cap nut 14 is screwed onto the sprinkler mounting screw 12, and a nipple 15 is attached to the cap nut 14.
is inserted, and an O-ring 18 is interposed between the lower collar 16 of the nipple and the shoulder 17 of the cap nut 14, and the eccentric force of the spring 18' maintains watertightness, making the sprinkler head 20 freely rotatable.
A male thread 19 is cut into the upper part, and a sprinkler head 20 is screwed onto this male thread 19 by a female thread 21.

The drive shaft 22 of the hydraulic motor 5 is connected to the upper plate 23 of the truck 1.
The worm 24 is attached to the drive shaft 22 and meshes with a gear 25 attached to the axle 3.

Although a gear type hydraulic motor is suitable for use in the present invention, other types of hydraulic motors can be selected and used as appropriate.

The embodiment is configured as described above, and its operation will be explained next.

Water supplied from the water supply pipe 9 enters the hydraulic motor 5 through the water inlet 8. The water pressure motor 5 is operated by the pressure of the water supplied at this time, and the drive shaft 22 and the worm 24 attached to the drive shaft 22 rotate together.
The rotation is transmitted to the gear 25 meshed with the worm 24, and the axle 3 to which the gear 25 is attached and the wheels 4 fixed to both ends of the axle 3 rotate together, and the trolley 1 carrying the base 6 and the sprinkler head 20 moves by itself. run

The water coming out of the drain port 10 of the water pressure motor 5 passes through the water pipe 11 and reaches the sprinkler head 20.
It is ejected from the nozzle 26 and the second nozzle 27. 1st
The water ejected from the nozzle 26 collides with the baffle plate 28 on its ejection trajectory, the baffle plate 28 is pushed away, and the arm 30 with the pendulum 29 rotates in the direction of the arrow about the pin 31. Arm 3 with pendulum 29
When the baffle plate 28 is removed from the jetting trajectory of the water by the rotation of 0, and the force to push it away is lost, the arm 30 with the pendulum 29 is rotated in the opposite direction to the arrow. At this time, rotational energy is accumulated in the pendulum 29 and it collides with the pillar 34 of the torii gate 33.

The sprinkler head 20 screwed onto the upper part of the nipple 15 is watertightly connected with the cap nut 14 and is rotatable, so that it is rotated in the direction opposite to the arrow by the rotational energy given by the collision of the arm 30 with the pendulum 29. It gradually rotates and moves on its own, withdrawing water in a circular pattern around the sprinkler.

〔effect〕

As explained above, according to the present invention, the sprinkler mounted on the trolley withdraws water while running on its own, making it possible to withdraw water over a wide range and to significantly reduce the number of sprinklers installed.
