Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for watering greens that can manage watering, particularly for growing grass on golf course greens and maintaining good growth conditions.

[Conventional technology]

Conventionally, the usual method for watering greens has been to use manual watering with a hose or a rotary sprinkler that moves back and forth in the left and right directions at a desired angle.

[Problem that the invention attempts to explain]

Conventionally, when watering greens, manual watering with a hose requires a considerable amount of labor and results in inconsistent watering conditions, and mechanical watering uses a sprinkler with 3 to 4 heads and requires 60% of water per hour. With a discharge amount of about min, the radius is approximately 15~
It covered about 16m.

That is, Fig. 4 is an explanatory diagram of the same, where G is green and S is
shows four sprinklers.

However, in such prior art, the water sprinkling locations sometimes overlap as shown in the drawings. For this reason, the overlapping area inevitably becomes overhumidified, which is undesirable, and in areas where undulation is large,
This tendency was severe, and since sprinklers had large water droplets, there was a large amount of water flowing on the surface. Therefore, penetration into the soil becomes insufficient and excessive penetration into low places occurs. As a result, in areas with low moisture, the roots become shallow, which may hinder the growth of grass or cause dryness, while in areas with high moisture, roots may be crushed or diseased, resulting in poor growth. This sometimes occurred.

In addition, moisture stagnant in low-lying areas can turn into hot water during high temperatures in the summer, or freeze during extremely cold seasons.Furthermore, since sprinklers usually discharge a large amount of water, overlapping and large water droplets can occur. For this reason, water could only be sprinkled two or three times at the same time. In other words, with the conventional techniques, it is difficult to obtain satisfactory irrigation water, and the amount of water used is extremely wasted.

Therefore, the present invention uses aerial spraying to uniformly mix water for spraying into a mist in an aerial area surrounded by planar endless mist pipes installed on the green, and then drops this misted water onto the green. The purpose is to eliminate surface runoff and effectively humidify the air and the ground.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention lays out a planar endless mist pipe on a green, and provides nozzles on the upper surface of the outer periphery of the mist pipe so as to be substantially opposite to each other, and from each nozzle to an aerial area surrounded by the mist pipe. A method was adopted in which water for watering is jetted out in substantially opposite directions under a desired pressure to form a mist, and the mist-form moisture is mixed in the above-mentioned aerial region and sprayed onto the green.

[Effect]

Spraying water by a desired means such as a sprayer into an air region surrounded by a planar endless mist pipe at a desired pressure while being supported by an air stream to form a mist;
The mist-like moisture is mixed in the air area surrounded by the mist tube and distributed evenly over the green over a long period of time, thereby providing an appropriate amount of moisture to the green.

〔Example〕

FIG. 1 is an explanatory plan view, FIG. 2 is a side view of the same, and FIG. 3 is a side view of a mist tube having a nozzle.

G is a green, 1 is a planar substantially annular mist tube arranged around the green G, and 2 is a plurality of nozzles provided at desired locations on the upper surface of the outer periphery of the mist tube 1 so as to be substantially opposite to each other. In FIG. 1, two sets facing each other, a total of four sets, are shown, but the number of installed sets is not limited to this and may be a plurality of sets that can substantially face each other.

3 is a water source, 4 is an electric oscillator, 5 is a blower, and 6 is a connecting pipe that connects the mist pipe 1 and the blower 5.

The mist pipe 1 is made of plastic or the like,
In this embodiment, as shown in the figure, a roughly flat rigid pipe or pressure-resistant hose is used, and it is laid on top of the green G or buried in the ground with nozzle 2 left, but in the case of burial, the nozzle can be opened and closed. A valve is provided for this purpose. Further, when the mist pipe 1 is installed on the green G, the mist pipe 1 may be made portable and movable depending on the watering location and watering area on the green G.

As shown in Fig. 1, the mist pipe 1 is formed into an endless planar substantially annular shape, so that the pressure inside the pipe is not impaired and the water spray pressure inside the mist pipe 1 is not reduced, and the spray pressure is less excessive or uneven. This is to ensure that the sprinkling water is uniformly and reliably ejected from each nozzle 2 with a distribution of . Furthermore, since the mist pipe 1 is formed into a planar substantially annular shape, it is possible to easily adjust the spray direction of the nozzles 2, which are arranged substantially opposite each other under a large circle at the installation site on the green G, without having to measure the mist pipe. This is also to ensure proper spraying of water for irrigation.

Then, the water from the water source 3 is sucked by the electric oscillator 4 (by the negative pressure on the suction side of the blower 5 or by another pressure source), and the water is made into a mist by the electric oscillator 4, and the water is made into a mist by the blower 5 as shown in FIG. The mist is fed under pressure to the mist pipe 1 which has a planar substantially annular shape as shown, and then is ejected obliquely upward in an aerial region above the green G surrounded by the mist pipe 1.

At an appropriate time, a portion of the mist is ejected in a planar arc shape from two sets of nozzles 2, which are provided opposite to each other on the upper outer periphery of the planar substantially annular mist tube 1, into an aerial area surrounded by the mist tube 1. As shown in FIG. 2, the mist mixes uniformly in the air above the green G and falls onto the surface of the green G together with other mist.

At this time, by changing the injection direction of each nozzle 2, for example, the direction of the injection hole in the horizontal and vertical directions, the spray angle and spray distance of the water sprayed into the aerial area surrounded by the mist pipe 1 can be adjusted. By changing the mixing time etc. of the water sprinkling water ejected from each nozzle 2, it is possible to adjust the degree of mixing (concentration) of the mist water in the air, and also adjust the time for the water to fall from a suspended state onto the green G. . Therefore, it is possible to spray water effectively in accordance with the growing situation of the lawn in each season.

Furthermore, since water is applied in the form of a mist to the Green G lawn by falling from the air, the pressure of the water ejected can bend the veins of the grass's leaves, hindering its subsequent growth. This prevents the growth of the lawn from being hindered by the nutrient soil being blocked or by the nutrient soil jumping up and sticking to the surface of the lawn, exposing the roots within the nutrient soil. I can do it.

Although one embodiment of the present invention has been described above,
The present invention is not limited to this, and the following elements may be added to the means.

(a) As the nozzle 2 gets further away from the blower 5,
The diameter of the mist tube 1 may be made small, thereby making the spray power from each nozzle 2 uniform.

(b) The nozzle 2 may be changed vertically or provided in multiple directions (for example, according to the shape of the undulation).

(c) Manual control valves may be provided.

(d) A timer method may be used.

(e) Sensors may be placed at important points on Green G to control the opening and closing states of each nozzle section depending on the descending state of the mist.

(f) Water pressure may be used to pressurize the water source.

(g) The mist tube is not limited to a planar substantially annular shape, but may be formed in a planar endless shape such as a polygonal shape such as a planar ellipse, a planar substantially square, or a planar substantially rectangular shape.

〔Effect of the invention〕
