Underground lifting type self-rotating spray head

Abstract

The invention discloses an underground lifting type self-rotating spray head and belongs to the field of irrigation equipment. The spray head comprises an outer pipe, an inner pipe, an elastic part, a self-rotating type water outlet mechanism and a hollow cone. The hollow cone is arranged at the upper end of the outer pipe, and the top of the hollow cone is provided with a water outlet. The outer pipe comprises a first pipe body and a second pipe body. A first baffle and a second baffle are arranged at the upper end and the lower end of the first pipe body respectively. The inner pipe is arranged in the outer pipe and can axially move. A third baffle is positioned at the upper end of the inner pipe, and a fourth baffle located between the first baffle and the second baffle is arranged at the lower end of the inner pipe. The elastic part sleeves the outer portion of the inner pipe and is located between the first baffle and the fourth baffle. The two ends of the self-rotating type water outlet mechanism are in sealed connection with the inner pipe and the hollow cone respectively. The self-rotating type water outlet mechanism comprises a water distribution pipe, a remote range nozzle arranged on the water distribution pipe, a near range nozzle, a jet flow hole and a bias plate. The bias plate corresponds to the jet flow hole, and the near range nozzle is arranged on one side of the bias plate on the water distribution pipe turning the back to the jet flow hole. The spray head can perform self-rotation by means of hydraulic power.

Description

Technical field [0001] The invention relates to the field of irrigation equipment, in particular to a lifting type spinning nozzle that can be used for underground burying. Background technique [0002] Sprinkler irrigation technology is an efficient water-saving irrigation technology for farmland, which can make water spray evenly and reduce the intensity of manual labor, and has a wide range of applications in today's agricultural operations. As the key equipment, the sprinkler device plays an important role in improving the efficiency of sprinkler irrigation. In order to avoid affecting the normal farming or harvesting in the field, some sprinkler devices that can be buried in the ground have appeared in recent years. [0003] For example, the prior art provides a buried rotary sprinkler head, including a housing structure, a gear transmission structure, a water outlet structure, and an adjustment mechanism. The gear transmission structure, the water outlet structure, and the a...
