The present invention relates to a sprinkler rotational force control device for use in crops or lawns, and more particularly, to a spraying nozzle for spraying a sprinkler, The spraying water is made to cancel out a part of the water by the force applied to the rotor by the rotation of the water pipe, and when the pressure of water supplied at the same time changes, the spraying angle of the spraying nozzle for close range spraying is changed by the spiral groove portion, The rotation speed of the sprinkler is maintained at a substantially constant speed even if the pressure of the water supplied to the sprinkler is changed.
In the past, sprinklers in the intermittently rotating state were not able to uniformly spray the water, and the muddy water tended to clog the crops, which was a serious obstacle to the growth of the crops. In the case of the regenerative utility models No. 20-0203265 and No. 20-0325181, since the supply of water is not smooth due to the outflow, the number of the atomizers is too large to supply water, and at the same time, There was no way to do it.
In the present invention, the upper end of the rotor 11 is closed with the Teflon 12 so that the resistance value is weak, and the resistance value of the rotor 11 is minimized while the rotor 11 is lifted by the leakproof packing having a different diameter. (For example, Ø2.4) 63 for a long distance spraying is assembled along the water pipes 20 and 30 assembled to the rotor 11 and a spray nozzle for short range spraying (for example, Ø2.4) is installed on the other side. 0) 73 is controlled to control the rotational force of the rotor 11, but the spraying nozzle 73 for spraying the near-by spray spreads the sprayed water through the spiral groove 56 and the circular key 55, And the control force is applied to the rotational force of the spraying nozzle 63 for far-reaching spraying as the direction changes.

Description

[0001] Turning effect controller for sprinklers [

The present invention relates to a sprinkler rotational force control device for use in crops or lawns, and more particularly, to a sprinkler control device for spraying water from a spray nozzle for long-distance spraying, The spraying water is made to cancel out a part of the water by the force applied to the rotor by the rotation of the water pipe, and when the pressure of water supplied at the same time changes, the spraying angle of the spraying nozzle for close range spraying is changed by the spiral groove portion, The rotation speed of the sprinkler is maintained at a substantially constant speed even if the pressure of the water supplied to the sprinkler is changed.

In the conventional case, the sprinkler in the intermittently rotating state using the elasticity of the spring was not able to uniformly spray the water and was intermittently scattered. At the same time, in the crops that the particles were too thick, the muddy water was trapped and the water- Respectively. The following will describe the case of Registration Practical Utility Model Nos. 20-0203265 and 20-0325181.

If the conditions of sprinkler usage are examined, the supply of water is not smooth due to the earthquake, so the maximum effect should be obtained with a small amount of water.

However, the above-mentioned techniques have a problem in the supply of water because the number of the atomizing nozzles is too large, and at the same time, the rotational force of the rotor is such that the sprayed water pushes out the atmosphere, The distance and spraying pressure and the amount of spray were the result of adding the rotational force to the rotor because the direction of the rotor was determined by the force applied to the rotor while pushing the air. Therefore, it is very sensitive to the pressure fluctuation of the water, and at the same time, there is no means for controlling the rotational force, and there is a problem in that rotation is accelerated. As the rotor turns faster, the arrival distance of the spray water discharged from the spray nozzle becomes shorter due to the air resistance value, and it can be seen that there is a remarkable difference in comparison with the arrival distance of the spray water in the static state.

The present invention has been made to solve the above problems by minimizing the number of nozzles, minimizing the number of revolutions of the rotor, reducing the air resistance of the spraying nozzle, In the radial direction of the supply water, even at a constant rotation speed.

The upper part of the rotor 11 is brought into contact with the Teflon plate 12 assembled with the closing plate 15 when the rotor 11 is assembled to the water pipe 10 as a rotary shaft. The closing plate 15 is movable up and down by the rotation prevention key 16 and the spring 14 so that the upper portion of the closing plate 15 is closed at the lower end of the pressing bolt 13. [

At the same time, the upper end of the rotor 11 is closed with the Teflon 12, but the resistance value is weak and the resistance value of the rotor 11 is minimized while the rotor 11 is lifted by the anti-leakage packing having a different diameter. (For example, Ø2.4) 63 is assembled along the water pipes 20 and 30 assembled to the rotor 11, and a spray nozzle for short-range spraying (for example, Ø2.4) is installed on the other side. 0) 73 is controlled to control the rotational force of the rotor 11, but the spraying nozzle 73 for spraying the near-by spray spreads the sprayed water through the spiral groove 56 and the circular key 55, (Not shown in the drawing), and the spraying direction of the water sprayed around the rotating shaft, which is the water pipe 10, toward the surface of the water is changed as the direction of the spraying nozzle 63 is changed (For example, Ø1.4), the spraying area a of the spraying nozzle for remote spraying (for example, Ø2.4) 63 and the spraying nozzle for spraying the local spraying (for example, Ø2.0) (Eg, Ø1.4) in the direction of the paper surface around the axis of rotation of the water pipe 10 (not shown in the drawing) And rock.

In the present invention, the rotational speed of the rotor is controlled by controlling the size of the spray nozzle, the size of the spray nozzle, the spraying direction, and the spraying direction so that the number of rotations of the rotor is kept constant. As shown in FIG. 3, by spraying the water of the fine particles evenly in the spraying areas a, b, and c of the respective spraying nozzles, it faithfully conforms to the requirement of the sprinkler used at the time when the water supply is not smooth .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic cross-sectional view of an embodiment of the present invention. FIG.
2 is a plan view of Fig.
Fig. 3 is a schematic view showing the area of the spraying water in the present invention. Fig.

The present invention will now be described in detail with reference to the accompanying drawings.

1, the sprinkler portion is detached from a conventional water supply pipe, and the lower end of the water pipe 10, which is a rotary shaft, is assembled to the pipe.

The upper portion of the rotor 11 having the packing for preventing water leakage having different diameters in the up and down direction is brought into contact with the Teflon plate 12 assembled with the closing plate 15. [

The closing plate 15 is pressed by the rotation bolt 13 and the rotation preventing key 16 and the spring 14 so as to be movable up and down.

(For example, Ø2.4) 63 for remote spraying along the water pipe 20 assembled to the rotor 11 and a spray nozzle for spraying the near-distant spray (for example, And an angle adjusting pipe 21 having a fixing bolt 22 is assembled to the water pipe 20,

A water pipe 40 is attached to the angle adjusting pipe 21 and an angle adjusting pipe 41 is attached to the water pipe 40. A washer 42 is disposed on the upper side of the angle adjusting pipe 41, 43) to fix the direction of the atomizing nozzle (e.g., 22.4) 63.

A water pipe 60 is assembled to the outside of the angle regulating pipe 41 and a rotation output member 62 (having a spiral groove of two or more in outer diameter) and a spray nozzle (for example, (63) are assembled together.

The water pipe 30 is provided with an angle adjusting pipe 31 having a fixing bolt 32. The water pipe 50 is arranged on the outer diameter of the angle adjusting pipe 31 and the water pipe 50 is fixed on the outer diameter of the water pipe 50 A spring 54 is provided on the upper side of the angle adjusting pipe 51 and the pressure plate 52 is pressed by a pressure adjusting bolt

A spiral groove 56 is formed in the angle adjusting pipe 51 so that the spray direction of the spray nozzle (e.g., 2 2.0) 73 is determined by the circular key 55 fixed to the water pipe 50 have.

A water discharge pipe 70 is assembled to the outer diameter of the angle regulating pipe 51 and a rotation discharge member 74 (having two or more spiral grooves on the outer diameter) is attached to the middle nipple 71 connected to the water pipe 70, And a spray nozzle 72 (e.g., a nozzle) 73 are assembled.

A nozzle (for example, Ø1.4) facing the circumferential surface of the water pipe 10, which is a rotary shaft, is disposed at an arbitrary portion of the bottom surface of the water pipe 21 or 31 (not shown in the drawing).

[Example]

When water is supplied to operate the sprinkler according to the present invention, the water flows into the water pipe 10 and is discharged through the spray nozzle, and the process will be described in detail.

The rotor 11 assembled in the water pipe 10 as the rotating shaft instantaneously rises due to the difference in diameter of the packing for leakage, and the resistance value of the packing is minimized by the lubrication by the water at this time, But it is possible to rotate at the minimum resistance value although it is closed to the Teflon plate 12 which can not be rotated by the rotation prevention key 15. [

First, the spraying direction of the spraying nozzle (e.g., 22.4) 63 for remote spraying is determined and fixed with fixing bolts 22, 43. At this time, the spraying state at the spray nozzle 63 is sprayed at a predetermined distance in the water flow state, but in the region (a) shown in FIG. 3, the sprayed water is sprayed evenly. This is the force applied to the rotor by the spraying pressure and the amount of spraying, the distance to the starting point of spraying around the water tube 10 being the reaction force, i.e., the reaction force, while pushing the atmosphere with the spraying water. Next, the spraying state of the spraying nozzle for short-range spraying (e.g., 22.0) 73 is adjusted and fixed by the fixing bolt 32. Meanwhile, the position of the circular key 55 is determined and the pressure adjusting bolt 53, (52) to adjust the elasticity of the spring (54) so that the position of the circular key (55) is at the center of the spiral groove (56).

If the pressure of the supply water changes, the spiral groove 56 slides around the circular key 55 whose direction of the atomizing nozzle (e.g.,? 2.0) 73 is fixed by the elasticity of the spring 54, (For example, ø2.0) 73 is changed. At this time, the rotational force remaining in the rotor 11 is made to be around 1 turn per 2 seconds. In the region of (b) shown in FIG. 3, Spray the water of the particles.

(Not shown in the drawing), a nozzle (for example, Ø1.4) facing the circumferential surface of the water pipe 10, which is a rotary shaft, is placed at an arbitrary part of the bottom surface of the water pipe 21 or 31, And to spray the water of the uncleaned particles in the area.
