Abstract

The present invention relates to a sprinkler. When a fluid flows in, each fluid gets to have straight inertia by passing through a linear section provided symmetrically to a rotor. The fluid now having straight inertia then rotates the rotor as the fluid passes by a bent section which is connected to a straight section, and is sprinkled in a radial direction of the rotor at the same time.

Description

{AGRICULTURAL ROTARY SPRINKLER}

The present invention relates to agricultural spiral coolers for sprinkling water or pesticides (hereinafter referred to as "fluids") for crop cultivation.

Generally, when growing agricultural products, it is advantageous that large crops can be cultivated with a small workforce by spraying water or agricultural chemicals (medicines) automatically using a sprinkler.

The spring cooler developed for such a purpose is known as a stock spring cooler which is installed by inserting a sprinkler on the ground, and a hanger type sprinkler which uses a sprinkler suspended in the air.

Ji stock sprinklers are mainly used in the open pit, while hanger sprinklers are used mainly in greenhouses and other facilities.

Since the present invention relates to a sprinkler for a hanger, a description of the sprinkler sprinkler will be omitted.

The hanger sprinkler is connected to the main water pipe and is installed at regular intervals in the empty space of the plastic house. An example of a conventional sprinkler is disclosed in Japanese Patent Application Laid-Open No. 10-2015-0065553.

However, in the above-described conventional sprinkler, the fluid is not sprayed to the lower portion of the sprinkler installed as the cyclone plate is rotated by the discharged water pressure and the fluid is sprayed in the radial direction along the swirling flow grooves.

Therefore, in order to solve this problem, the conventional sprinkler needs to be installed in such a way that the sprinkling radii are overlapped with each other, thereby increasing the amount of the sprinkler installed.

In addition, the aforementioned sprinkler has a problem in that the falling water from falling down from the sprinkler during the operation of the cooler may fall on the leaves or roots of the crop or the crop that is being cultivated, thereby damaging crops.

The present invention has been made in view of the above-described problems of the conventional sprinkler, and it is an object of the present invention to provide a sprinkler which can spout fluid at different spraying radii simultaneously through one sprinkler, To prevent the agricultural products from being concentrated in one place.

In the agricultural rotary sprinkler of the present invention,

A fluid having a linear inertia is contained in the fluid while passing through a linear section symmetrically provided to the rotor when the fluid flows into the rotor, and the fluid having the linear inertia passes through the bending section connected to the straight section, And is characterized in that the fluid is radiated in the radial direction of the rotor.

The present invention is characterized in that a water droplet scattering wing is further provided to the fluid flowing down to the body of the rotor so that the fluid collected by the scattering wing is blown away by the centrifugal force of the rotating rotor, so that water droplets are not concentrated in one place.

The present invention can provide two different spraying radii through a single sprinkler as well as extend or reduce the spraying radius of the spray cooler.

In addition, the fluid flowing along the surface of the rotor is gathered at the end portion of the water droplet scattering wing provided on the rotating rotor, and scattered by the centrifugal force, so that the water droplet does not continuously drop to one place.

Further, since the outer diameter of the shaft provided at the lower portion of the rotor is smaller than the outer diameter of the rotor body, the foreign matter does not flow into the bearing due to the centrifugal force that is rotated.

The pressure adjusting tip 113 causes the fluid flowing through the branch tube 130 to be discharged through the discharge port 113a.

If the inner diameter of the discharge port 113a of the pressure regulating tip is changed to a small inner diameter, the water or medicines introduced from the branch pipe 130 can be discharged with a high water pressure during discharge.

The bearing 114 has a shaft hole 114a provided at the center at a predetermined depth in the axial direction.

Referring to FIG. 6, FIG. 6 is a vertical cross-sectional view of the sprinkler of the present invention, showing the organic coupling relation of the components of the sprinkler 100 of the present invention.

The above-described sprinkler 100 is made of a synthetic resin material made of a synthetic resin material and is not corroded, and is free from corrosion even when used for a long time.

6, the sprinkler 100 of the present invention is rotatably coupled between the discharge port of the pressure regulating tip and the shaft hole 114a of the bearing, so that the fluid introduced from the branch pipe is embedded in the straight section L1 As the straightness inertia is applied to the wall surface of the bending section L2, the rotor 120 is rotated and the fluid is sprinkled on the crop.

5 (b), when the heights h1 and h2 of the curved portions L3 on both sides are different from the heights h1 and h2 of the curved portions L3 on both sides, The radius of watering can be different.

That is, in Fig. 5 (b), the height "h2" has a larger water spray radius than "h1", so that water or medicine can be watered farther than the height "h1".

Accordingly, the present invention can provide two different spraying radii through one sprinkler 100, so that the spraying radius of the sprinkler can be expanded or reduced by application thereof.

The water flowing along the surface of the rotor by the water droplet scattering vane 123 of the rotating rotor 120 is collected in the end portion of the water droplet scattering vane 123 and flows in the radial direction by the centrifugal force, There is nothing that does not fall.

Since the shaft 124 provided at the lower portion of the rotor is formed to be smaller than the outer diameter of the body 120a, the rotor 120 can not rotate because the water does not flow into the bearing 114 due to the centrifugal force .
