DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying device for lawn irrigation, which is useful for performing an irrigation operation such as fertilization, injection of a chemical solution, or aeration by intermittently driving a high-pressure liquid into lawn. .

[0002]

2. Description of the Related Art Fertilization, aeration and the like are indispensable for maintenance and management of lawns in golf courses and the like, especially for maintenance of turf in cold regions that form green. The aeration work is to introduce air to the root of the lawn to help the lawn grow.For example, a method in which high-pressure water is sprayed from a nozzle onto the lawn surface to form many small cavities in the ground Is being developed. Fertilizers and pesticides are mixed into the high-pressure water as needed, so that fertilization and pesticide spraying can be performed at the same time.

[0003] Conventionally, as a device for this purpose, a three-wheel or four-wheel type self-propelled vehicle is filled with a plurality of nozzles whose injection ports are oriented toward a lawn surface and a liquid such as a pesticide injected from the nozzles. A lawn in which all element parts including a tank and a high-pressure pump for pumping the liquid in the tank toward the nozzles are mounted, and an operator can get on the vehicle and perform aeration work or the like while driving. Irrigation devices have been developed and are widely used.

[0004]

By the way, as an approximation, there is a movement to spread cold grass on the fairway as well as on the green. However, if this situation develops in the future and becomes the general appearance of golf courses, lawn care will be extensive, and conventional lawn irrigation devices will also require liquid storage in terms of running capacity. It is clear that there will be a large capacity shortage in capacity. Therefore, when considering future lawn irrigation equipment as an extension of the existing concept, when the size of the driving engine and tank is increased,
As a result, it is inevitable that the entire irrigation apparatus will be increased in size and cost.

The present invention has been made in view of such circumstances, and has as its object to provide a new and useful lawn irrigation injection apparatus which can be suitably applied to a wide area.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

[0007] That is, a turf irrigation injection device according to the present invention comprises a tank and a liquid for spraying liquid in the tank.
It is used in conjunction with a tank truck equipped with a watering device, and is used for drawing out a driven vehicle pulled by the tank truck and a liquid mounted on the driven vehicle and stored in the tank truck . A high-pressure pump, and a nozzle which is also mounted on the driven vehicle and injects a liquid discharged from the high-pressure pump toward a lawn surface.
The tank is selectively connected to the sprinkler or high-pressure pump.
It is characterized by being able to continue .

[0008]

The present device is used in conjunction with a tank truck, and its self-propelling ability and liquid storage capacity depend on that of the tank truck, and other element parts unique to irrigation, for example,
It consists of only an injection nozzle that moves with the injection port facing the grass surface and a high-pressure pump that raises the liquid to an appropriate pressure. Therefore, even if the application place is vast, tank vehicles usually have no problem in running capacity and liquid storage capacity.Therefore, it is necessary to use a device with a large number of nozzles and a large pump capacity as the device. That's enough. In addition, the tank truck has a tank and this tank.
And a sprinkler for spraying the liquid in the tank.
Therefore, the inside of the tank is switched from the high pressure pump by the switching mechanism.
To reconnect to the sprinkler, replace the tanker truck
It can also be used as a vehicle for watering.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

A turf irrigation injection device 1 shown in FIG. 1 is used in conjunction with a tank truck 2.

The tank truck 2 is used for watering generally owned by golf courses. A tank 21 having a self-propelled engine is provided on a vehicle 21 equipped with a large tank 22 and a hose 23 for spraying water. A low-pressure pump 24 for pumping water stored in the tank 22 is mounted on the hose 23.
In using the present apparatus 1, a tow hook 25 is provided at the tail of the vehicle 21, and water containing a medicine necessary for aeration or the like is stored in the tank 22.

The irrigation injection device 1 is constructed by mounting a pump unit 12 and a nozzle unit 13 on a driven vehicle 11 supported by two wheels. The driven vehicle 11 has its front end connected to the hook 25 of the tank truck 2 via the arm 11a and is towed. The pump unit 12 includes a high-pressure pump 12b connected to the tank 22 of the tank truck 2 via a hose 12a, and a pump engine 12c that drives the high-pressure pump 12b. At a position not shown, a watering device is selectively provided in the tank 22.
To the low-pressure pump 24 or the high-pressure pump 12b
A switching valve as a switching mechanism is mounted. The nozzle unit 13 includes a frame 13a, a support mechanism 13b that supports the frame 13a so as to be able to move up and down with respect to the lawn surface G, and a plurality of nozzle units 13 that are arranged on the frame 13a with their injection ports directed downward. Injection nozzle 13 orthogonal to
c, the high-pressure pump 12b
And a piping section (not shown) for distributing and supplying the pressurized liquid discharged from the apparatus.

Then, when the worker gets on the tank truck 2,
By towing the device 1 and running on the target road surface while operating the pump engine 12b, the liquid pumped up from the tank 22 and pumped to each nozzle 13c is ejected from these nozzles 13c and jetted from the lawn surface G Is driven into.

As described above, the present apparatus 1 leaves the self-propelling ability and the liquid storage ability to that of the tank truck 2 and only the element parts specific to irrigation which cannot be covered by the irrigation, namely, the pump unit 12 and the nozzle unit 13 Is mounted on the driven vehicle 11. Therefore, even if the application place is large, there is no problem in the running ability and the liquid storing ability of the tanker truck 2, and only the large-capacity nozzle unit 13 or the pump unit 12 is used as the present apparatus. It will be compatible. As described above, the present apparatus 1 is put to practical use on the premise that the tank truck 2 which is an existing facility is used, and only the necessary minimum component parts are mounted. Therefore, compared with the case where the conventional lawn irrigation apparatus is directly upsized, the newly required cost can be reduced to an incomparable level, and the load when changing the pump capacity and the number of nozzles can be reduced significantly. In addition, the combined use of the present apparatus 1 also has an effect that the effective utilization rate of the tank truck 2 which is an existing facility can be significantly increased.

The specific configuration of each part is not limited to the illustrated embodiment, but can be variously modified without departing from the spirit of the present invention.

[0016]

As described above, the lawn irrigation apparatus of the present invention is based on a completely new concept different from the existing apparatus, and basically includes only element parts unique to high-pressure injection, such as high-pressure pumps and nozzles. It is mounted on a vehicle, the vehicle is towed by a tank truck, and liquid is supplied from the tank truck. Therefore, the high running capacity and liquid storage capacity required when applied to a vast area can depend on the tank truck, and this device is kept to the minimum necessary configuration, and is inexpensive and easy to use. Can be In addition, since the use of the tank truck is expanded, there is an effect that the effective utilization rate is increased. That is, in the present invention,
Lawn irrigation by connecting the high pressure pump inside the tank
It is possible to perform the work and connect the inside of the tank to the sprinkler
By fixing the driven vehicle
The vehicle can be used as the original watering vehicle.
