Description

Technical Field

[0001] This utility model relates to the field of irrigation sprinkler technology, and more specifically to a high-efficiency water conservancy irrigation sprinkler. Background Technology

[0002] Irrigation sprinklers play an important role in industrial production and agricultural irrigation. With their increasing application, market demand is steadily growing. Irrigation sprinklers can precisely control the amount of water sprayed and the uniformity of spraying, avoiding surface runoff and deep seepage losses, and greatly improving water utilization. However, the rotational force generated by the liquid jet of current high-pressure sprinklers results in a short service life and they are prone to clogging after prolonged use, affecting irrigation efficiency. Therefore, a high-efficiency irrigation sprinkler is needed to solve these problems.

[0003] Because the current nozzles lack a deceleration component to reduce the kinetic energy of the water flow, they cannot filter out impurities in the water again. Therefore, the problem is solved by adding a deceleration device and a cleaning component. Utility Model Content

[0007] Preferably, the lifting assembly includes a first protective cover, a motor, a worm gear, a worm wheel, a lead screw, and a nut. The first protective cover is fixedly connected to one side of the bottom of the machine body. The motor is installed on the side of the first protective cover away from the machine body. The output shaft of the motor is fixedly connected to the worm gear. A worm wheel is arranged parallel to one side of the worm gear. A lead screw is installed at the top of the worm wheel. A nut is installed at the end of the lead screw away from the worm wheel. One side of the nut is fixedly connected to the outer side of the first cylinder body. A groove for the nut to move is provided on one side of the machine body.

[0008] Preferably, the cleaning assembly includes a scraper and a filter screen, wherein the scraper is movably disposed inside the first cylinder and is disposed close to the inner side wall of the first cylinder, and the filter screen is disposed parallel to the bottom end of the scraper.

[0010] The technical effects and advantages of this utility model are:

[0011] To utilize the nozzles more efficiently and extend their lifespan, a planetary reduction gear is used to reduce the rotational speed caused by the kinetic energy of the water flow. The centrifugal force generated during the high-speed rotation of the water wheel can cause additional tension on the nozzle structure, potentially leading to deformation or damage. Therefore, the planetary reduction gear extends the nozzle's lifespan. Simultaneously, the water wheel's rotation drives a scraper fixedly connected to the shaft, cleaning impurities from the filter screen and preventing water blockage that could render the nozzle unusable. The motor's output shaft drives a worm gear fixedly connected to it, causing the lead screw to rotate and raise or lower the body, ultimately raising or lowering the entire nozzle. This height control allows for precise control of the spray distance. Attached Figure Description

When the motor 202 is started, the output shaft of the motor 202 drives the worm gear 203 fixedly connected to it to rotate, ultimately causing the entire nozzle to rise and fall.

[0023] The rotating assembly 3 includes a water wheel 301, a partition plate 302, a water flow hole 303, a fixed plate 304, a second protective cover 305, a planetary reduction gear 306, and a rotating shaft 307. The fixed plate 304 is fixedly installed inside the second cylinder 104. The water wheel 301 is movably disposed at the top of the fixed plate 304 and the top of the interior of the second cylinder 104. The partition plate 302 is installed on one side of the water wheel 301. The water flow hole 303 is opened on the fixed plate 304 and is located on the side of the partition plate 302 away from the water wheel 301.

The other end of the rotating shaft 307 passes through the bottom end of the second protective cover 305 and is fixedly connected to the scraper 401.

[0024] The cleaning component 4 includes a scraper 401 and a filter screen 402. The scraper 401 is movably disposed inside the first cylinder 102 and is disposed close to the inner side wall of the first cylinder 102. The filter screen 402 is disposed parallel to the bottom end of the scraper 401.

[0025] The nozzle assembly 5 includes a nozzle 501, a seal 502, a fastener 503, and a fixing block 504. The bottom end of the fixing block 504 is fixedly connected to the top end of the second cylinder 104. The fastener 503 is movably disposed inside the bottom end of the fixing block 504.

[0026] The working principle of this utility model:

[0027] Water supply end 105 connects to the water source. Water flows through the inside of the first cylinder 102 and is filtered twice by the filter screen 402 to prevent impurities in the water from clogging the nozzle. Then, the water enters the second cylinder 104 through the rotating cylinder 103 and flows out through the water outlet 303. The partition plate 302 controls the direction of the water flow. The water flow hits the blades of the water wheel 301. The large impact of the water flow transfers the kinetic energy of the water to the water wheel 301, making it rotate at high speed. The water wheel 301 is movably connected to the second protective cover 305 through the rotating shaft 307, which is used to reduce the input speed of its rapid rotation to the slow output speed required for rotation, thereby extending the service life of the nozzle. The rotation of the water wheel 301 drives the scraper 401, which is fixedly connected to the rotating shaft 307, to rotate, cleaning the impurities attached to the filter screen 402 and preventing the water flow from clogging and making the nozzle unusable.

[0028] Finally, the motor 202 is started. The output shaft of the motor 202 drives the worm gear 203, which is fixedly connected to it, to rotate. This drives the worm wheel 204, which is set parallel to it, to rotate. This causes the lead screw 205 to rotate, which drives the nut 206, which is fixedly connected to the machine body 101, to rise and fall. Finally, the entire nozzle rises and falls, thereby controlling the spray distance by controlling the height of the nozzle.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
