Description

Jet pressure controlling tool

The present invention relates to a jet pressure regulating mechanism, and to a jet pressure regulating mechanism for supplying a variable pressure to the ejection pressure of the fluid introduced into the body periodically.

Hoses are commonly used for agricultural irrigation. Water drawn up from a source such as a motor is moved to a desired place through the hose and sprayed on crops by using a separate injection means. In particular, a fountain hose is used to directly supply crops or grass while water is being moved, without using the separate injection means.

In general, the fountain hose has a configuration such that the water in the hose to which the pressure of a certain size is applied is ejected through the injection hole formed in the side wall. The fountain hose is formed to form a group of one or more injection holes at regular intervals.

However, when water is ejected through two or more holes formed on the left and right sides of the conventional fountain hose and is separated from the supply source, the ejection pressure is rapidly lost and it is difficult to transport the water to a long distance. Accordingly, in order to transfer the water to a long distance, it was necessary to use a pressurization device having a high pressing force or to install a pressurization device in the middle separately, resulting in a cost factor for it, and easy adjustment and installation that can be used. An instrument was required.

An object of the present invention for solving the above problems is to provide a jet pressure regulating mechanism to be supplied to the pressure of different sizes according to the time of outflow of the fluid by periodically interrupting the supply amount of the fluid introduced into the body. will be.

Another object of the present invention is to provide a jet pressure control mechanism that allows the opening and closing body reciprocating up and down about the rotating shaft rotated while the fluid is supplied to adjust the ejection pressure by varying the supply amount by adjusting the supply amount of the fluid. .

In addition, the locking protrusion may be formed at a portion close to the inlet of the hose connecting pipe for inflow of the fluid, or at an outlet thereof.

In accordance with a preferred embodiment of the present invention, the guide means is an example formed so that the anti-rotation key and the corresponding groove is formed facing each other in pairs to the opening and closing body, the guide bar formed in the longitudinal direction of the body, All examples made of grooves formed in the opening and closing body so as to span the guide bar are applicable.

In addition, the driving means may be applied to both the case of the blade that is rotationally driven while the fluid hits, and the case of a motor that is always rotated at a constant speed irrespective of the inflow or outflow of the fluid.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The embodiments of the present invention described below are merely intended to illustrate the technical idea of the present invention by way of example, it should not be understood that the scope of the present invention is limited thereto. Various modifications, changes and variations are possible in the following examples which will be apparent to those of ordinary skill in the art.

First, referring to FIG. 1, a conceptual drawing of the present invention is disclosed, and it can be seen that the fountain hose 200 is connected to the front and rear ends of the ejection pressure adjusting mechanism 100. In this case, the hose connected to the front end of the jet pressure control mechanism 100 may be a general hose or a water supply source, not the fountain hose 200.

The jet pressure regulating mechanism 100 of the embodiment according to the present invention is shown in FIG.

Referring to FIG. 2, the ejection pressure adjusting mechanism 100 has a cylindrical body 2 having an inlet 14 and an outlet 16. The body 2 has a front and a rear end in a longitudinal direction. The rotary shaft 4 is fixed to the shaft support 10 so as to be rotatable, and the vane 6 is fixed to the distal end of the rotary shaft 4. Then, the opening and closing body (8) for adjusting the amount of water supplied to the inside of the body (2) is formed while moving from side to side along the axis with the rotary shaft (4) as the center.

On the outer circumferential surface of the rotary shaft 4 is formed a rail 12 to move the opening and closing body 8 in both directions, by the rotation of the rotary shaft 4 subsequent to the rotation operation of the blade (6) The opening and closing body 8 is configured to be movable in both the left and right directions along the rail 12. And, a guide means is provided between the body 2 and the opening and closing body 8, as shown, the guide groove 84 in the longitudinal direction is formed in the inner portion of the body 2 and corresponding thereto Guide protrusions 82 are formed in the longitudinal direction on the side of the opening and closing body 8.

The specific operation of the jet pressure regulating mechanism 100 according to the present invention configured as described above will be described.

First, as the fluid is supplied through the inlet port 14 of the ejection pressure adjusting mechanism 100, the wing 6 is rotated, and at the same time the rotary shaft 4 is coupled to the blade 6 is rotated. At this time, the opening and closing body 8, which is fitted with the rotary shaft 4 is moved along the rail 12, the opening and closing body 8 is not rotated, but only reciprocating linear movement to the left and right. The reason why the opening and closing body 8 is not rotated but only a linear movement to the left and right is because the rotation is suppressed by the guide means consisting of the guide groove 84 and the guide protrusion 82 as described above, but slips.

At this time, when the opening and closing body (8) proceeds in the same direction as the flow of water flowing from the inlet to the outlet, the transverse distance (D) between the opening and closing body (8) and the body (2) becomes smaller, the rear of the opening and closing body (8) The opening and closing surface 85 reduces the discharge area of the outlet portion of the body 2. As a result, the amount of water discharged is reduced, and the jet pressure of the water supplied to the fountain hose 200 is lowered. At this time, while the supply amount of the water jetted from the fountain hose 200 is lowered and the jet distance is also reduced, water is supplied at a distance close to the fountain hose 200.

A specific example of the opening and closing body 8 is shown in FIG. 3. The opening and closing body 8 has a cylindrical curved shape and is supported while being inserted into the rotating shaft 4 at the front and the rear. The front and rear inner side support portions of the opening and closing body 8 are provided with locking projections 80 and 81 which are moved along the rails 12 formed on the rotary shaft 4. And, the central side portion of the opening and closing body 8 is open in a mesh, so that the flow of the introduced water is easily made.

On the contrary, when the opening and closing body 8 approaches the wing 6 while the transverse distance D increases in response to the flow of water, the rear end surface of the opening and closing body 8 is the outlet portion of the body 2. As it moves away from the discharge area is increased, and the amount of water discharged is increased, the jet pressure of the water supplied to the fountain hose 200 is increased. Therefore, as the amount of water supplied from the fountain hose 200 increases and the pressure thereof increases, water is ejected from the fountain hose 200 to a far distance.

That is, as shown in FIG. 7 and the variable pressure is generated in the fountain hose 200, the reach distance after the fluid is ejected can be seen to vary. In the case where the maximum ejection pressure is formed, the fluid reach reaches the position of 'A' and the lateral distance D becomes smaller, and the ejection pressure becomes minimal as the amount of water supplied through the outlet decreases. Is reached and reaches the position of 'C' through 'B'. Then, if the lateral distance (D) is increased while the wing (6) continues to rotate, the water discharged inside the jet pressure control mechanism 100 quickly exits through the outlet, the jet pressure is increased, As a result, the fluid's reach reaches 'A' through 'B'.

As described above, the ejection pressure is controlled by opening and closing the outlet by the left and right movement of the opening and closing body 8, wherein the rotation and direction switching process between the rotating shaft 4 and the opening and closing body 8 is also illustrated. It will be described more clearly with reference to 3 and 4.

First, referring to FIG. 4, a diagram showing a rotating shaft 4 of the present embodiment is disclosed, in which a threaded rail 12 is formed. In particular, the rail 12 is formed to be reciprocating in both directions without moving in only one direction, for example, consisting of a rail 12 in both directions as the left and right screws are formed at the same time have. In addition, the end portions of each direction of both ends of the rail 12 are connected to each other, which is to allow the switching body 8 to change directions.

First, the operation in the case where the opening and closing body 8 proceeds in the direction of the outlet port 16 will be described.

As water flows in through the inlet 14, the blade 6 is rotated and at the same time the rotary shaft 4 is rotated. At this time, the positions of the locking projections 80 and 81 of the initial opening and closing body 8 are located at points L and L1, respectively, and gradually start to slide down the rails 12. As described above, the opening and closing body 8 has a linear motion, not a rotational motion, and proceeds toward the outlet 16. When the operation continues and proceeds to the turning point M formed at the end of the rail 12, the traveling direction is naturally reversed and goes back in the opposite direction.

The reason why the direction is reversed goes back along the rail 12 which is naturally connected when the engaging projection 81 formed at the end of the opening and closing body 8 proceeds to the turning point M. At this time, since the locking projection 80 in the opposite direction of the turning point M is placed at the center M1 of the intersection point of the rail 12 corresponding to the inflection point of the turning point M, it naturally goes up in the direction in which the traveling direction goes down. It is reversed. In this way, the moving direction is reversed and the operation continues, but this time, when the locking projection 80 comes to the start of the rail 12, the moving direction is reversed again. That is, as the locking projections 80 and 81 are positioned at the turning point L and the crossing point L1 of the rail 12, the traveling direction is naturally reversed.

In the above case, the rail 12 is formed over the entire surface of the rotary shaft 4, but otherwise, when the engaging projections 80 and 81 are formed only at the front end or the rear end of the opening and closing body 8, The rail may be formed only at a portion corresponding to the moving distance of the locking protrusions 80 and 81. That is, the rail 12 may be formed only in the section of any one of the front end or the rear end of the rotation shaft (4).

An example of the anti-rotation structure of the opening and closing body 8 according to the preferred embodiment of the present invention is shown in FIG. 5.

Referring to FIG. 5, guide bars 86 are formed at both sides in an inner portion of the body 2 in the longitudinal direction of the body 2, and the opening and closing having guide grooves 88 including the guide bars 86. Sieve 8 is formed. By the anti-rotation structure having such a configuration, as shown in the example of FIG. 2 described above, the opening and closing body 8 is not rotated at the same time by the rotation of the rotation shaft 4, but only linear movement along the rail 12.

A longitudinal cross-sectional view thereof is shown in FIG. 6. The opening and closing body 8 which is moved along the rail 12 while the rotating shaft 4 is rotated is not rotated by the mutual supporting operation of the guide bar 86 and the guide groove 88, but is straight as described above. Only the reciprocating motion will take place.

In addition, although the above-mentioned example mentioned the ejection pressure adjustment by the rotation of the blade 6 as a drive means, the motor (not shown) can be provided in the front end of the rotating shaft 4 otherwise. In this case, the opening and closing operation of the opening and closing body 8 may be performed at a predetermined cycle by a constant rotational speed of the motor, and there is an advantage that a stable operation may be performed regardless of the amount of water supply or discharge.

When the distance between the rails 12 and the screw, for example, the pitch is widened or narrowed, the moving distance of the opening and closing body 8 according to the rotation of the rotary shaft 4, that is, the transverse distance D Of course, as the change in the jet pressure change period is changed, the cycle of changing the reach of the water jetted through the fountain hose 200 is a natural change.

Thus, according to an embodiment of the present invention, when the ejection pressure of the fluid is periodically changed with the passage of time, when using a fountain hose connected to it, the reach of the fluid varies with time, so that the supply of the fluid with the fountain hose It can be done evenly regardless of perspective.

According to the present invention, the supply of the fluid introduced into the body by the opening and closing operation of the opening and closing by the rotation of the rotating body is periodically interrupted by the effect of supplying the fluid at different sizes of pressure depending on the time of the outflow of the fluid There is.

In addition, the opening and closing body reciprocating up and down about the rotating shaft rotated while the fluid is supplied adjusts the supply amount of the fluid so that the ejection pressure is adjusted through the fountain hose by varying the supply amount so that the fluid is evenly distributed regardless of the perspective of the fountain hose. There is a supply effect.
