Description

[Detailed explanation of the invention] This invention is based on a relatively large area of land (garden, park, playground,
The present invention relates to a watering device suitable for watering fields (fields, etc.).

Conventionally, when watering the land as described above, if there is a water source nearby, such as a water tap or an industrial water tap,
This was done by connecting a hose to the faucet and sprinkling water from the tip of the system.

If there is no water source nearby, either directly sprinkle water with a water tank truck loaded with a water tank filled with water, or connect the faucet hose of the water tank truck as above and use the end of the hose to spray water directly. I tried to sprinkle water on the ground.

However, the water sprinkling method described above has many problems as described below.

That is, when sprinkling water by connecting a hose to a faucet, a large amount of human power (labor) is required, especially when the area to be watered is wide.

In addition, direct watering with a water tank truck □ is effective on vast playgrounds, etc., but when the target of watering is lawns or crops, the water tank truck d < d cannot enter the land, and therefore the watering area is Water supply was limited, or as mentioned above, watering had to be done manually using a hose.

From this point of view, it is an object of the present invention to provide a watering device that can sprinkle water without any hindrance, even in lawns, fields, etc., which are inaccessible to watering tank trucks, etc., without requiring much human labor. The purpose is

For this reason, the watering device according to the present invention includes a conduit that can be connected to a water supply source via a hose at one end, has a valve to open and close at the other end, and is connectable to another watering device via the hose. It is characterized in that it is supported by a movable trolley and that a water sprinkling pipe with a water nozzle attached to its tip is connected to the middle part of the conduit.

Therefore, when the land is large, the watering device according to the present invention can be used in such a way that by connecting each other via hoses, one water supply source can be used to water multiple locations at the same time. Efficient water spraying can be performed without manual intervention.

Hereinafter, specific examples of the present invention will be described in detail with reference to the accompanying drawings.

In the sprinkler system shown in FIGS. 1 to 4, 1 is a movable trolley with a total of four wheels 2 attached to its lower side, and on two beams lag1a that are passed across the trolley 1, there are Fittings 3a, 3a that stop the conduit 3 by shifting it to one side in the longitudinal direction of the trolley 1
In addition, in the middle of the conduit 3,
Water sprinkling pipes 4 are connected vertically upward, and a water sprinkling nozzle 5 is attached to the upper end of the water sprinkling pipe 4.

In the ζ diagram, reference numeral 6 denotes a reel for storing the hose in a manner that allows it to be wound up and unwound freely. It is rotatably supported in a bearing 8.8 provided at the top of the 7.7.

The hose is wound on the reel shaft 6a on the opposite side of the water spray pipe 4.
This is done by turning the handle 9 attached to the end of the.

One end 3A of the conduit 3 is formed as a connection port with a hose so that it can be connected to a faucet of a water supply source or a conduit of another watering device via a hose. The other end 3B is similarly formed as a connection port to which a hose can be connected.

In this case, one connection port 3A is used as a water inlet, and the other connection port 3B is used as a drain port.

In addition, an on-off valve (see Fig. 5, 1O) for opening and closing the conduit 3 is provided on the drain port 3B side of the conduit 3, so that when the water sprinkler is connected in series via a hose, the final It is preferable that the drain port 3B side of the sprinkler device located at the end can be closed off.

Next, a method of using the above-mentioned watering device will be explained.

FIG. 5 shows a case where two water sprinklers AjB are used to sprinkle water on a lawn or the like where the water tank car C cannot enter, using the water tank car C as the water supply source.

As shown in the figure, the faucet c of the water tank car C has a hose,
Connect one end of hose h, and connect the other end of hose h to 1. Connect to the inlet 3A of the conduit 3 of the water sprinkler.

The one sprinkler device B has its inlet port 3A connected to the drain port 3B of the sprinkler device A via a hose h', and the drain port 3, the B side, is equipped with an operating valve 10. I'll block this off.

If the area to be watered is wide, a larger number of watering devices may be appropriately arranged so that the entire area can be watered.

I moved far away from water tank truck C. In order to be able to sprinkle water even in places, the connecting hose h between the watering tank car C and the watering device A is long, and for this reason, a special hose h with a large diameter take-up reel D exclusively for this connecting hose is used. A special cart E may be provided.

In the above condition, when the water faucet C of the water tank truck C is opened, the water in the tank is led to the conduit 3 of the first water sprinkler A through the hose h, and the drain port of the conduit 3 3B is also led to the conduit 3 of the second sprinkler B via a hose h'.

This 4. The drain port 3B of the conduit 3 is closed by the on-off valve 10, and the internal pressure of each conduit 3, 3 increases, and as a result, the water that has risen inside each water sprinkling pipe 4. From 5 = water is sprinkled all at once.

Various known types of watering nozzle FIV5.5 can be used depending on the target to be watered, but in the case of a large area to be watered such as a ground or lawn, a sprinkler that sprays water while the nozzle rotates is used. It is suitable to use.

Further, when the water supply source is a water supply or an industrial water supply, the water tank truck C is not necessary, and a hose may be connected to the tap of the water supply.

When the water sprinkling is finished, the water sprinkling tank truck C is moved, and the water sprinkling devices A and B are moved to the next location □ to perform the next water sprinkling.

When watering in the entire area is completed, each connection hose hjh
' can be wound up and stored on the take-up reels D and 6, respectively.

In addition, in the above-mentioned embodiment, the water sprinkler device was moved by human power, but there is no doubt that it may be a self-propelled type.

Examples in this case are shown in FIG. 6 and FIG. 8.

In this embodiment, a hydraulic drive device is incorporated into the water sprinkler device explained in FIGS. 1 to 5 so as to use hydraulic power.

That is, 11 is a hydraulic motor installed in the middle of the conduit 3, which rotates an internal impeller with the hydraulic power supplied from the inlet 3A of the conduit 3, and transmits this rotational force to the output shaft 11a (fixed pulley 12 and this V bell N between pulley 12,
,,3. The speed reduction device 1.5 is connected to the
through this speed reduction device 15, and further to the pulley 16.
．． ■The belt 17 transmits the rotational force to the V-belt ho and the heel 19 attached to the front wheel drive shaft 18, and the water sprinkler
I'm trying to run it.

As mentioned above, when the power device is installed on the trolley 1,
By supplying water from the inlet 3A of the conduit 3, it is self-propelled.

Because it is possible to move by human power 4'! , unnecessary, yell.

The moving speed in this case can be adjusted in various ways by adjusting the speed reduction device 15.

Although the casing is not shown in the drawings, it can be made self-propelled by not using the hydraulic motor 11 and using another power source, for example, an electric motor.

Furthermore, it is also possible to employ various movement controls and systems so that the sprinkler device can be remotely controlled using a radio.

As described above, the present invention supports a conduit with a connection port that can be connected to a water supply source at one end on a trolley that can be used as a shield, and connects a water sprinkler pipe in the middle of the conduit. A water sprinkling device is provided in which a water sprinkling nozzle is attached to the tip and the water sprinkling nozzle is supported above a cart.

Therefore, according to the present invention, since the device can have a simple structure, it can be manufactured lightweight and inexpensively, and by interconnecting multiple devices, it does not require much manpower even on vast areas. In addition to being extremely efficient, water can be sprinkled without any hindrance even in areas where water tank trucks cannot be accessed, and there is no need to deploy a special water network, reducing facility costs. can be made cheaper.

In addition, if a trolley and a take-up reel for the hose are installed, the hose can be easily stored, and if the trolley is self-propelled, efficient watering work can be done without requiring much human labor. can be done.
