Detailed Description

As shown in the figure, the single-row hanging hook counterweight type hanging and spraying device for the greenhouse with the width of 6-20 meters comprises a single-row main water conveying pipe 1 and hanging and spraying components which are uniformly connected to the single-row main water conveying pipe 1, wherein the hanging and spraying components comprise a hanging and spraying water conveying pipe 2, a spring type water jacking ball valve 3, a hanging and spraying nozzle 4 and a hook counterweight 5. The single-row main water pipe 1 is made of PE pipes, the hanging and spraying water pipe 2 is made of 8/11 capillary pipes, the quick connector 7 is made of 8/11 water faucet and is quickly connected with the water faucet, a four-quarter internal thread buckle is arranged on the water faucet, a four-quarter external thread is arranged on a water inlet pipe of the hanging and spraying nozzle 4, and a hook type counterweight pendant 5 is hung at the bottom of the hanging and spraying nozzle 4. The bottom of the hanging spray nozzle 4 is hung with a hanging hole of a hook type counterweight 5 and the hanging spray nozzle 4 are integrally formed or fixedly arranged on the hanging spray nozzle 4 through threads. The water spray flow path 10 of the rotor 14 of the overhead shower head 4 is 2 or more and directed upward, and the high-pressure water discharged from the water outlet 8 pushes the rotor 14 to rotate at a high speed while spraying water through the water spray flow path 10. The water outlet of the water spraying channel 10 is provided with an upward slope 11 of 0-60 degrees, so that the water is sprayed out at an upward angle.

The connection mode is that the barb part of the PE barb bypass 6 is connected to the single-row main water pipe 1, the socket part is connected to the hanging and spraying water pipe 2 and is screwed and fixed through the quick connector 7, the other end of the hanging and spraying water pipe 2 is connected with the faucet quick connector 7 for 8/11 pipes, and the other end of the hanging and spraying water pipe 2 is provided with the 8/11 faucet quick connector 7. The quick connector 7 is in threaded connection with the hanging spray nozzle 4, a spring type water ejecting ball valve 3 composed of a spring and a water ejecting ball is arranged in a water inlet pipe of the hanging spray nozzle 4, and the water ejecting ball is abutted to a sealing rubber ring at the pipe orifice of the hanging spray water pipe 2. The working principle of the spring type water jacking ball valve 3 is as follows: when the pressure of water flowing in the water flowing pipeline rises, the pressure above the water ejecting ball 301 is greater than the designed pressure value, for example, 0.15MPa (equivalent to 1.5 kg of pressure), the water outlet 8 is opened downwards by the pressure above the water ejecting ball 301, when the pressure of water inside the water flowing pipeline falls, the pressure in the water pipe is less than 1.5 kg of pressure, under the thrust action of the spring 302 below the water ejecting ball 301, the water ejecting ball 301 automatically rebounds to close the water outlet 8, the water flow of the water outlet 8 is blocked, and the effect of storing water inside the pipeline is achieved. When the hanging spray nozzle 4 is installed in an inverted suspension mode, when the pressure in a water pipe is smaller than 1.5 kilograms of pressure when a water pump is turned off, the water ejecting ball 301 automatically rebounds under the elastic action of the spring 302 to block a water inlet pipe opening of the hanging spray nozzle 4, residual water in a pipeline is blocked to drop onto a seedbed and the ground, and water flow and water drops are effectively prevented from damaging the seedbed and the ground. A hook type counterweight pendant 5 is hung at the bottom of the hanging spray nozzle 4. The hook type counterweight drop 5 can be of an integrated structure, can also be a shell made of flexible materials such as plastic with a sealing cover, and is convenient to store due to the structure that water or fluid such as sand and soil are filled in the shell. The water quantity control valve 13 of rotation type is provided with on hanging the inlet tube of shower nozzle 4, can be according to the different crops in the same big-arch shelter, or different irrigation width etc. manual regulation water spray, and is more accurate to the accuse of water-saving irrigation.

The PE barb bypass 6 is integrated as shown in figures 10 and 11, or is split as shown in figures 8 and 9, meanwhile, the fittings of 8/11 capillary can be replaced by the fittings of 8/12 capillary or 9/11 capillary or 9/12 or 10/12 capillary, the diameter of the water outlet 8 of the overhead shower nozzle 4 is 2.0mm to 8.0mm, the flow of the rotating wheel 14 of the overhead shower nozzle 4 is 200L/H to 800L/H, and when the rotating wheel 14 meets the requirement of the water spraying flow of 200L/H to 800L/H, the water spraying angle is inclined upwards by 0-60 degrees.

For example: when the diameter of the water outlet 8 is 2.5 mm, the upward inclined spraying angle is 10 degrees and the distance from the ground is 1.2 meters, the spraying diameter distance is 7 meters wide. When the diameter of the water outlet 8 is 2.5 mm, the hanging height is still 1.2 m, and the upward inclined spraying angle is 20 degrees, the spraying width is 8 m. When the diameter of the water outlet 8 is increased from 2.5 mm to 3.2, the hanging height is 1.2 m from the ground, and the spraying angle inclined upwards is 20 degrees, the spraying width is 9 m. When the diameter of the water outlet 8 is 4.2 mm and the upward inclined spraying angle is 20 degrees, the maximum width can be sprayed to the greenhouse with the diameter of 12 meters net width. When the diameter of the water outlet 8 is 4.2 mm and the hanging height is 1.9 m, the spraying angle inclined upwards is increased from 20 degrees to 35 degrees, and the greenhouse with 13 m net width can be sprayed furthest. When the diameter of the water outlet 8 is 4.2 mm and the hanging height is 1.9 m, the upward inclined spraying angle is 45 degrees, and the greenhouse with the net width of 14 m is sprayed. When 8 delivery port was 5.2 millimeters, hang highly for 1.9 meters, and upward inclination sprays for 20 degrees, can spray 13 meters wide big canopies, and when 8 when unchangeable distances on delivery port and ground, the spraying angle of upward slope can spray 15 meters wide big canopies when being 35. When the distance between the water outlet 8 and the ground is not changed, the greenhouse with the width of 16 meters can be sprayed when the upward inclined spraying angle is 45 degrees. When the delivery port of 8 is 8.0 millimeters, hang when 1.9 meters apart from ground, the spraying angle that upwards inclines is 45, can spray 20 meters wide big-arch shelters furthest. From the above data, one can conclude that: when the distance between the water outlet and the ground is not changed, the first factor influencing the water spraying diameter is the size of the water outlet 8 at the joint of the rotating wheel 14, and the second factor is the angle of the rotating wheel 14 for spraying water in an upward inclined manner under the condition of the same size.

The lower end of the periphery of the rotary wheel 14 is also coaxially provided with an atomizing runner 12. One end of a spring of the spring type water ejecting ball valve 3 is abutted against the step-shaped end surface in the water inlet pipe of the hanging spray nozzle 4, and the other end of the spring 302 is connected with a water ejecting ball 301. The water-ejecting ball 301 is abutted against the sealing rubber ring at the pipe orifice of the hanging and spraying water pipe 2. When the water inlet pressure is large enough, the water pushing ball 301 is pressed down, the water enters the hanging spray nozzle 4 and flows out from the water outlet 8 of the hanging spray nozzle 4, the water flow pushes the rotating wheel 14 to rotate and is sprayed out from the water spraying port at the edge of the water spraying flow channel 10 in an upward inclined angle, the water above the atomizing rotating wheel 12 is directly sprayed out, the rest water pushes the atomizing rotating wheel 12 to rotate quickly, the atomized water falls into the ground at the near end of the hanging spray nozzle 4, and the uniformity of plant irrigation at the near end of the hanging spray nozzle 4 is fully ensured. The outer frame of the hanging spray nozzle 4 can be fixed or can be rotary driven by water flow, and the structure is the prior art and is not described again.

The water spray channels 10 of the rotary wheel 14 may be uniformly arranged in the cylinder of the rotary wheel 14 as shown in fig. 4 and 5, or may be protruded outside the rotary wheel 14 and symmetrically arranged as shown in fig. 12. The two symmetrically arranged water spraying flow channels 10 are S-shaped, the S-shaped suspended spray nozzles 4 are of two types, one type is provided with an outer frame 9, as shown in figure 13, and the rotating wheel 14 has the advantages of better aggregating the water spraying force and improving the spraying width. The second method, without the outer frame 9, as shown in fig. 12, has the advantages of improving the cohesion of water, increasing the spraying width, reducing the resistance of the outer frame 9 to the rotating water flow, and realizing the effect of spraying at 360 degrees without dead angles.
