Description

Technical Field

[0002] Sprinkler irrigation technology is used to ensure that crops in farmland are not short of water and to increase their growth rate. Patent document CN216604430U discloses an agricultural sprinkler device comprising: a base; and a hydraulic telescopic rod, the bottom end of which is fixed to the top of the base. The agricultural sprinkler device provided by the utility model drives a servo motor to rotate a rotating shaft. The rotation of the rotating shaft indirectly drives a gear to rotate, which indirectly drives four arc-shaped top blocks to compress a telescopic spring. This causes the four rectangular blocks to drive a support frame to expand outward, and the movement of the support frame indirectly drives the movement of the sprinkler head. Once the support frame reaches a suitable position, the servo motor is turned off, and the pump body on the hose is driven. The pump body sprays water from the water tank through the sprinkler head onto crops at a distance. This allows for easy adjustment of the device according to user needs, facilitating the different needs of users and simplifying the operation of the device, making it easier for workers to use.

[0003] The coverage of the above-mentioned sprinkler irrigation is very limited. In order to achieve irrigation in a larger range, fixed-point jet irrigation can be used, which is more economical and practical. However, the distance of the jet is affected by the jet angle. The installation angle of existing jet sprinkler heads is mostly fixed, or horizontal rotation is used to expand the irrigation surface. Based on this, the existing sprinkler irrigation device has the problem that the jet angle cannot be automatically adjusted, which is inconvenient to irrigate crops near and far, resulting in many blind spots in irrigation, which needs further improvement.

[0023] A driving mechanism is installed on the surface of the mounting support rod 1 , which drives the lifting platform 7 to move up and down and drives the rotating seat 2 to rotate at the same time.

[0024] Specifically, the driving mechanism includes a driving motor 8 and a driving shaft 9. The driving shaft 9 is rotatably connected to the mounting support rod 1. The driving motor 8 is fixedly mounted on the surface of the mounting support rod 1 and drives the driving shaft 9 to rotate. A turntable 10 is fixedly mounted on the end of the driving shaft 9.
