Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation equipment technology, and more specifically to a nozzle of a buried sprinkler irrigation device. Background Technology

[0002] Sprinkler irrigation is an advanced irrigation technology that saves water while achieving significant irrigation effects. Due to increasing global water scarcity, in the coming years, arid regions will primarily rely on micro-irrigation, including sprinkler and drip irrigation; while in non-arid regions, it is essential to improve water use efficiency. Global natural conditions vary greatly, including arid, semi-arid, semi-humid, and humid regions. Areas with low rainfall urgently need to develop water-saving irrigation technologies, while even in areas with abundant rainfall, seasonal droughts—spring, summer, and autumn—frequently occur due to uneven rainfall distribution. Therefore, sprinkler irrigation technology has gained global attention and is widely used.

[0003] In existing technologies, the nozzles of buried sprinkler irrigation devices are often buried underground before use. When in use, the nozzles need to be dug out, and then the spray boom can push the nozzles up from the ground. If the nozzles are not dug out, the spray boom cannot lift the soil on top of the nozzles, which is time-consuming and laborious.

[0004] Therefore, how to provide a sprinkler head for an underground sprinkler irrigation device that can automatically moisten the soil at the top of the nozzle during use and automatically extend out of the soil during use is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a nozzle for an underground sprinkler irrigation device, which aims to solve the problems in the background art mentioned above, so as to automatically moisten the soil at the top of the nozzle during use and automatically extend out of the soil during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sprinkler head for an underground sprinkler irrigation system includes: An outer tube, wherein the outer tube is arranged vertically; A water inlet plate is disposed at the bottom of the outer sleeve, and the side wall of the water inlet plate is fixedly connected to the inner wall of the outer sleeve. A gearbox is disposed inside the outer sleeve. Multiple connecting plates are arranged in a circular array on the outer wall of the gearbox. The end of each connecting plate away from the gearbox is fixedly connected to the outer sleeve. A vertical shaft is rotatably connected inside the gearbox. The bottom of the vertical shaft extends out of the gearbox. An impeller is disposed at the bottom of the vertical shaft. An output shaft is disposed at the top of the gearbox. A cover plate is disposed on the top of the outer sleeve, and a water outlet pipe is provided through the cover plate, which is connected to the output shaft for transmission. A water spray head is provided with multiple water outlets. The water spray head is fixedly connected to and communicates with the water outlet pipe. A top water outlet is provided on the top of the water spray head.

[0007] Furthermore, the water inlet plate is provided with multiple water permeable holes, all of which are inclined, and the inclination direction of the water permeable holes is opposite to the inclination direction of the blades on the impeller.

[0008] Furthermore, an internal gear ring is provided on the inner wall of the gearbox. The gearbox is a planetary gear reducer. The sun gear of the planetary gear reducer is mounted on a vertical shaft. Planetary gears are connected to the circumferential direction of the sun gear. Multiple planetary gears are provided. The end of the planetary gear away from the sun gear is connected to the internal gear ring for gear transmission. The planet carrier on the planetary gear rotates. The planet carrier is fixedly connected to the output shaft.

[0009] Furthermore, a transmission frame is provided at the top of the output shaft. The transmission frame includes a lower plate, a lower deflector plate, an upper deflector plate, and an upper plate. The upper plate is sleeved on the water outlet pipe. The outer wall of the upper plate is rotatably connected to the cover plate. The upper deflector plates are spaced apart at the bottom of the upper plate. The lower plate is disposed on the output shaft and rotates synchronously with the output shaft. The lower deflector plates are disposed on the lower plate and abut against the upper deflector plates. The lower deflector plates drive the upper deflector plates. Multiple upper and lower deflector plates are provided.

[0010] Furthermore, a sealing gasket is provided on the top of the upper plate, and the sealing gasket is in frictional connection with the inner wall of the cover plate.

[0011] Furthermore, the spray head is provided with a first water outlet, a second water outlet and a third water outlet. The spray head has a conical structure. The first water outlet and the second water outlet are respectively located on both sides of the spray head. The third water outlet is located above the first water outlet and the second water outlet. The top water outlet is located at the tip of the spray cone.

[0012] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a sprinkler head for a buried sprinkler irrigation device. By setting an impeller, water can drive the impeller when water passes through the sprinkler head. The impeller can drive a reducer, and the output shaft of the reducer drives the sprinkler head to rotate. Thus, in use, the sprinkler head can drill through the soil by rotating it. By setting a top water inlet at the top of the sprinkler head, which is connected to the outlet pipe, water can be delivered to the top of the sprinkler head during use, which can moisten the soil above the sprinkler head, reduce the soil hardness, and facilitate the sprinkler head to drill through the soil, making it convenient to use.
