Description

Sprinkler with fall prevention and pressure compensation

The present invention relates to a sprinkler used to sprinkle water or drugs (pesticides, fertilizers, etc.) evenly in various directions when cultivating various crops, and more particularly, to a sprinkler having a function of preventing falling water and adjusting pressure.

In general, sprinkler (sprinkler) is a device used to sprinkle water or drugs (pesticides, fertilizers, etc.) in all directions when growing a variety of crops, mainly installed to have a constant height from the ground or the ground.

For example, as shown in FIG. 1, the water pipe 1 is installed on the ground, the connection hose 2 is connected to the water pipe 1 at regular intervals, and the sprinkler 3 is connected to the front end of the connection hose 2. Is installed, the sprinkler (3) is fixed to the holding table (S) through the fasteners (4), when the water pump (not shown) to supply the water to the water pipe (1), the water pipe ( 1) As the water pressure is formed inside, the water is supplied to the connection hose 2, and the nozzle of the sprinkler 3 is rotated to spray water into the crop.

As a related art, Korean Patent Laid-Open Publication No. 1995-0013583 has a head that is convex upward, has a substantially hemispherical shape, and is detachably mounted at an upper end of a pipe, and can spray liquid using a plurality of nozzles. Liquid sprinklers are described.

However, the above-described conventional sprinkler 3 does not have a fall prevention function, so crop damage is frequently caused by falling water.

That is, when the water pressure of the water pipe 1 drops, the amount of water flowing into the sprinkler 3 from the connection hose 2 decreases, so that the residue remaining inside the connection hose 2 and the sprinkler 3 can be smoothly sprayed. As it falls down and falls to the ground as water droplets form at the bottom of the nozzle, excessive water supply impedes the growth of surrounding crops.

In addition, the sprinkler connected close to the pump has a high water pressure to provide sufficient watering and watering distance, but the sprinkler installed far from the pump has low water pressure so that the watering and the watering distance are irregular or the water is not supplied to the crop smoothly. do.

In addition, when the crop cultivation site is a slope such as a ridge, the water pressure difference supplied from the pump is very high. As shown in FIG. 2, the sprinkler (a) closest to the pump and the sprinkler (b) at the middle point close to the bottom of the slope. And the water pressure of the sprinkler (c) located farthest and the highest is a> b> c, and moreover, since the difference in height occurs from the sprinkler (a) to the sprinkler (c), the water pressure is located in the high place. As the sprinkler (c) becomes weaker, and thus the spraying amount of water is not uniform for each section, there is a problem that the variation in the amount of spraying is increased and the water can not be evenly irrigated to the crop.

The present invention has been made in order to solve the above problems, by using a sprinkler applied to the fall prevention and pressure correction function at the same time, the spraying operation only when the proper pressure is maintained above, if the water is below the appropriate pressure to prevent the falling water Therefore, it is possible to reduce the amount of watering between the sprinklers installed before and after, and to minimize the damage of crops due to the falling down, and to compensate for the pressure deviation, so that a certain amount of water can be sprayed on the farmland. Of course, the object of the present invention is to provide a sprinkler having a fall prevention and pressure correction function that enables even watering even on a slope.

The present invention is formed on one side of the lower inlet connected to the connection hose; A cylindrical cover installed in the horizontal direction on the other side of the lower side and opened at one end thereof, a stretch plate installed at the open end of the cover and stretched by hydraulic pressure, and a pressing member installed inside the cover to contact the stretch plate; Falling prevention unit including a spring provided between the pressing member and the cover; A flow path portion formed in an upper side of the inflow portion in a horizontal direction, the horizontal flow passage being opened and closed according to the expansion and contraction of the expansion plate, and a vertical flow passage communicating with the horizontal flow passage and formed in the vertical direction; And a pressure compensator communicating with the vertical flow passage, the pressure compensating plate being installed to be movable therein, and correcting the amount of water sprayed according to the water pressure; and a sprinkler having a fall prevention and pressure correction function.

At this time, the inlet is characterized in that it comprises a connection pipe connected to the connection hose, and an inflow path through which water introduced into the through the connection pipe flows.

In addition, the stretch plate is characterized in that any one selected from silicone, rubber, urethane, latex, elastomer.

In addition, the fall prevention portion is deformed convex to the cover side by the water pressure of the water introduced through the inlet portion, the pressing member pushed by the deformed expansion and contraction plate to press the spring to open the flow path portion It is also characterized by the configuration.

Further, the cover is also characterized in that the through-hole communicating with the outside is formed at the other end closed.

In addition, the pressure compensator, to secure the flow space in which the pressure compensation plate flows therein, the locking ring jaw formed in the inlet groove on the side wall, and formed to extend to the lower side of the locking ring jaw to control the cracking off of the pressure compensation plate It is also characterized in that it comprises a projection and an annular protrusion formed downwardly projecting inside the locking ring jaw and the watering hole is formed in the center.

Here, the intermittent projection is also characterized in that the lower end is formed to be bent toward the inside.

In addition, the annular protrusion is characterized in that the bone is formed around the sprinkler.

In addition, the pressure compensation plate is characterized in that it is made of any one selected from silicone, rubber, urethane, latex, elastomer.

The present inventors have a conventional sprinkler does not have a fall prevention function, crop damage frequently occurs due to falling water, in particular, the amount of water spraying is not uniform for each section on the slope, the variation of the amount of spraying water increases, and thus even watering the crop Recognizing that there is a problem that cannot be solved, and research and efforts to solve this problem, by using a sprinkler that applied the fall prevention and pressure compensation at the same time, the spraying operation only when the proper pressure is maintained, In this case, the water supply is blocked and prevented from falling down, which can reduce the amount of watering between the sprinklers installed before and after, and minimize the damage of crops caused by the falling water. Water can be sprayed evenly on slopes The present invention has been completed with a sprinkler having possible fall prevention and pressure compensation functions.

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

Sprinkler 10 having a fall prevention and pressure correction function according to the present invention is largely as shown in Figs. 3a to 4 inlet 100, fall prevention 200, flow path 300 and pressure correction 400 is made, and may further include features of the watering unit 500.

The inlet part 100 is formed to be biased at one side of the lower end and is connected to the connection hose (2). Conventional sprinkler inlet is formed at the bottom center, but in the present invention, the fall prevention unit 200 should be installed on the other side of the lower portion of the sprinkler, forming the inflow passage 120 in the lower one side by the hydraulic pressure Since the expansion and contraction plate 220 of the prevention unit 200 has to be expanded and contracted, the inlet part 100 is formed on one side of the lower side unlike the prior art.

In this case, the inlet part 100 includes a connection pipe 110 connected to the connection hose 2 and an inflow path 120 through which water introduced into the connection pipe 110 flows.

The fall prevention unit 200 includes a cover 210, a stretch plate 220, a pressing member 230 and a spring 240.

Here, the cover 210 is formed in a cylindrical shape, it is in the horizontal direction on the other side, the inner end is formed to open, the other end is formed to be closed.

The cover 210 is formed in the closed other end of the through-hole communicating with the outside 211, which is to facilitate the stretching operation of the expansion and contraction plate 220 to be described later, if the through-hole 211 does not exist If not, a vacuum is generated between the cover 210 and the pressure member 230 according to the expansion and contraction of the expansion and contraction plate 220, so that the elastic force by the spring 240 is not sufficiently transmitted to the expansion and contraction plate 220. This is because the plate 220 does not operate smoothly.

In addition, the expansion and contraction plate 220 is installed in the vertical direction at the open end of the cover 210, and expands and contracts by the water pressure of the introduced water.

At this time, the stretch plate 220 may be made of any one selected from silicon, rubber, urethane, latex, elastomer, these are not only excellent in elasticity, but also excellent in heat resistance, oxidation resistance and chemical resistance as well as water In some cases, it is also suitable for spraying drugs such as pesticides and fertilizers.

The pressing member 230 is installed inside the cover 210 to be in contact with the expansion and contraction plate 220, and a spring 240 is connected between the pressing member 230 and the cover 210. .

As a result, the expansion and contraction plate 220 is deformed to be convex toward the cover 210 by the water pressure of the water introduced through the inflow unit 100, and the pushed by the expansion and contraction plate 220 is thus deformed. The pressing member 230 pressurizes the spring 240 so that the expansion and contraction of the expansion and contraction plate 220 is facilitated, thereby opening the inlet 100 and the flow path 300 in communication.

The flow path part 300 is composed of a horizontal flow path 310 and a vertical flow path 320, the horizontal flow path 310 is formed in the horizontal direction on the upper side of the inlet portion 100, the expansion plate 220 In communication with the inflow passage 120 of the inlet portion 100 according to the expansion and contraction of the inlet or closed.

In addition, the vertical passage 320 has a lower end in communication with the horizontal passage 310 and is formed in a vertical direction, and the upper end is configured to be connected to the pressure correction unit 400.

The pressure compensation unit 400 is in communication with the vertical flow path 320, the pressure correction plate 410 is installed to be able to flow in the inside, it is configured to correct the watering amount according to the water pressure.

Here, the pressure compensation unit 400 includes a pressure correction plate 410, a locking ring jaw 420, an intermittent protrusion 430 and an annular protrusion 440.

The pressure compensation plate 410 may be made of any one selected from silicone, rubber, urethane, latex, elastomer, these are not only excellent in elasticity, but also excellent in both heat resistance, oxidation resistance and chemical resistance as well as water Therefore, it is also suitable for spraying chemicals such as pesticides and fertilizers.

The locking ring 420 has a flow space 422 through which the pressure compensating plate 410 flows, and the pressure compensating plate 410 is installed in the flow space 422 so as to be movable. Inlet grooves 421 are formed on the sidewalls of the hook ring 420 so that water passing through the vertical flow path 320 is introduced through the inlet grooves 421.

The intermittent protrusion 430 is extended to the lower side of the locking ring jaw 420 to control the separation of the pressure compensation plate 410. At this time, the intermittent protrusion 430 may be formed so that the lower end is bent toward the inside.

On the other hand, when the water pressure of the incoming water is low so that the pressure compensating plate 410 is caught on the lower end of the intermittent projection 430, the water floated between the pressure compensating plate 410 and the hooking jaw 420 (450) It also flows into).

The annular protrusion 440 is made of an annulus formed with a sprinkling hole 441 in the center, it is formed projecting downward on the inside of the engaging ring projection (420).

As such, since the annular protrusion 440 smaller than the diameter of the pressure compensating plate 410 is formed to protrude downward from the inside of the locking annular projection 420, the pressure compensating plate 410 is not in close contact with the ceiling surface of the pressure compensating part. Therefore, the water for the spraying is not blocked and the pressure is corrected so that a certain amount of water can be controlled to spray.

At this time, the annular protrusion 440 may be provided with a recess 442 formed in the periphery of the sprinkling hole 441, so that the correction of the pressure can be made more smoothly by forming the valley 442.

The sprinkling part 500 is installed on the upper portion of the sprinkler, the rotating plate 510 is provided with the rotation, the rotating plate 510 is sprayed on the lower side by moving to the upper side by the water pressure of the water supplied into the sprinkler Sphere 531 is exposed to the outside, the pressure-corrected water by the pressure correction unit 400 is discharged to the outside through the sprinkler 531 is made of watering.

In addition, a rotating rod 520 is connected and installed at the upper center of the rotating plate 510, and a spraying nozzle 530 is provided at a lower portion of the rotating plate 510, and the spraying hole 531 is disposed at one side of the spraying nozzle 530. ) Is formed, the rotating plate 510 is moved upward by the water pressure of the water so that the sprinkler 531 is exposed to the outside, the water is sprinkled around the sprinkler through the sprinkler 531 exposed to the outside Will be.

At this time, the water spray nozzle 530 is automatically rotated while the water having a proper pressure or more hit the side wall of the water spray nozzle 530 during the watering process, so that even water spraying for the crops grown in the surrounding area where the sprinkler is installed. It is done.

In addition, the sprinkler may be connected to a support line, such as a wire (H) is formed on the top, the upper side is installed by the connecting ring (H).

In addition, the connection pipe 110 has a connection protrusion 111 protruding along the outer circumferential surface for connection with the connection hose, and a thread formed along the lower outer circumferential surface of the connection protrusion 111 for direct connection and fixing to the water pipe. 112 and a tip 113 formed diagonally inclined at the bottom.

Therefore, as shown in FIG. 6, the sprinkler 10 having a fall prevention and pressure compensation function according to the present invention may be directly connected to the water pipe 1 by the external structure of the connection pipe 110. .

Hereinafter, with reference to the drawings will be described in detail with respect to the operation of the present invention.

First, in the state shown in FIG. 5A, when water comes up under pressure through the water pipe 1 or the connection hose 2 on the lower side by the pump, the inflow path is passed through the connection pipe 110 of the inlet 100. When the pressure is maintained above the appropriate pressure 120, the expansion and contraction plate 220 of the fall prevention unit 200 is pushed by the hydraulic pressure while the pressure member 230 presses the spring 240 to expand and contract the plate ( The 220 is deformed to be convex toward the cover 210 side, whereby the horizontal flow passage 310 of the flow path portion 300 and the inflow passage 120 of the inflow portion 100 communicate with each other to be opened.

Therefore, spraying works only when the proper pressure is maintained above, and when the water is below the proper pressure, the water supply is blocked and the falling water is prevented, so the variation of watering can be reduced between the sprinklers installed before and after, and the crop damage caused by the falling water can be minimized. have.

And, as shown in Figure 5b, the water is moved upward through the vertical flow path 320 through the horizontal flow path 310 to reach the pressure compensation 400, where the locking step (according to the magnitude of the water pressure ( The pressure compensating plate 410 flows in the up and down direction in the flow space 422 of the 420, and the opening degree of the inflow groove 421 or the excited space between the pressure compensating plate 410 and the hooking projection 420. By adjusting the opening degree of 450, even if a pressure deviation occurs, it can be appropriately corrected so that a certain amount of water can be controlled to be sprayed on farmland, thereby allowing even watering even on slopes as well as flat land.

That is, in the case of the sprinkler connected close to the pump, since the water pressure of the introduced water is high, the pressure compensating plate 410 is largely flowed upward so that the inflow space through which the water can be introduced is automatically adjusted, and the sprinkler connected far from the pump Since the water pressure of the introduced water is low, the pressure compensation plate 410 flows small to the upper side and is automatically adjusted to form an inflow space so that water can be sufficiently introduced.

As such, the water whose pressure is corrected by the pressure compensator 400 is rotated by the rotating plate 510, which is moved upward by the water pressure, and rotates in a predetermined amount through the sprinkler 531 installed on the side of the sprinkling nozzle 530. Water can be sprayed on farmland.

In particular, even in the case of severe pressure variations such as flat land as well as inclined land, by automatically correcting this to reduce the variation in the amount of water sprayed by controlling a constant amount of water can always be sprayed on farmland by section, even watering is possible. Become.

Then, when the pump stops the operation to block the supply of water, the compressed spring 240 of the fall prevention unit 200 is extended to press the pressure member 230 connected thereto to the inflow path 120, Accordingly, while the expansion and contraction plate 220 is returned to its original state, the expansion plate 220 is blocked between the inflow portion 100 and the flow path portion 300 to prevent falling water through the water spraying portion 500.

As a result, the sprinkler 10 having a fall prevention and pressure correction function according to the present invention by using a sprinkler applied to the fall prevention and pressure correction at the same time, the spraying operation only when the proper pressure is maintained above, if the water supply is less than the appropriate pressure Is prevented from falling down, so it is possible to reduce the amount of watering between the sprinklers installed before and after, and to minimize the damage of crops caused by the falling down, and to compensate for even the pressure deviation, a certain amount of water can be sprayed on the farmland. By controlling so as to allow even watering on the slope as well as flat land.

As described above, the present invention has been described in detail by using a preferred embodiment, but the scope of the present invention is not limited to the specific embodiment, it should be interpreted by the appended claims. In addition, those of ordinary skill in the art that various modifications and applications are possible without departing from the scope and spirit of the present invention.

The present invention can reduce the amount of sprinkling variation between sprinklers, minimize the damage of crops due to falling down, and even if the pressure deviation occurs by controlling it to spray a certain amount of water on farmland evenly on slopes as well as flat land Since watering is possible, there is industrial possibility.
