2. Description of the Related Art For example, when water is sprinkled for the above-mentioned purpose in a cultivation house, as shown in FIGS. 9 and 10, the water is sprinkled substantially horizontally above a groove b between adjacent ridges a. By connecting the water pipe 1 to the water supply pipe 2 and connecting the water supply pipe 2 to a water source such as a water tank (not shown) and supplying water from a water source with a pump (not shown), the water pipe 1 From the fountain nozzle 10 provided so as to face both sides, the fountain is sprayed toward the crop c in a spray state or in a state close thereto.

[0003]

In the case of water sprinkling as described above, it is necessary to sprinkle the crop c so as to be as uniform as possible over the entire crop c, but at an angle from the fountain nozzle 10 as shown by arrow A in FIG. When water is sprayed, the water particles are not sufficiently distributed in the front area between the fountain nozzles 10, while the water particles are excessively supplied to the area where arrow a overlaps. Water is evenly sprayed. Therefore, when it is generally necessary to perform sufficient watering, the partial excess amount results in wasted watering. Further, the above problems can be solved to some extent by providing the fountain nozzles 10 smaller and more densely so as to spread evenly, and increasing the water supply pressure. However, in this way, the pump pressure is limited and the fountain a May not reach the center of.

An object of the present invention is to provide a water sprinkling method and a water sprinkling apparatus which can improve the above-mentioned drawbacks and can spray water more uniformly and without waste.

A sprinkling pipe, and a water supply pipe arranged to connect the water supply tank and other water sources with the sprinkling pipe,
It is characterized by comprising a drive mechanism for reciprocating the water spray pipe within a predetermined range along the longitudinal direction of the water spray pipe, and a flexible tube connecting the water supply pipe and the water spray pipe. It is preferable that each of the water spray pipes is hung by a rail or a wire or other guide installed above the water spray pipe in parallel with the water spray pipe via a pulley. The drive mechanism includes a rotatable shaft installed at a position apart from both ends of the sprinkler pipe in a state substantially orthogonal to an extension line of the sprinkler pipe, and a wheel fixed to the shaft.
And a chain or wire that connects both ends of the sprinkler pipe and is tensioned on the wheel, and a motor that rotates both or one of the shafts. . When installing the sprinkler pipe in a cultivation house, it is piped substantially horizontally between adjacent ridges in the house, and the fountain nozzles of the sprinkler pipe are directed to both sides or one side of the sprinkler pipe. It is preferable to provide a large number at regular intervals. Further, when water is sprinkled from a different level by the same sprinkling pipe, all or part of the fountain nozzle is provided on a sprinkling branch pipe connected to extend downward or upward of the sprinkling pipe. Is preferred.

[0007]

In the water sprinkling method of the present invention, for example, the water spouting pipe is provided with the fountain nozzles facing to the side at an interval of 1000 mm,
Moreover, when the adjacent fountain nozzles are set so as to face in opposite directions, water is sprayed while reciprocally moving the water spray pipe in the longitudinal direction within a range of about 1,500 to 2,000 mm. Water can be sprayed so that water particles are evenly distributed. According to the sprinkler of the present invention, the sprinkler pipe is movably arranged along the longitudinal direction of the sprinkler pipe, the water supply pipe from the water source and the sprinkler pipe are connected by the flexible tube, and the sprinkler pipe is reciprocated. Since the drive mechanism is provided, the above-described method of the present invention can be carried out reliably, smoothly and efficiently.
