Open flow passage type rotating nozzle capable of being applied to ground covering

Abstract

The invention discloses an open flow passage type rotating nozzle capable of being applied to ground covering, and belongs to the field of irrigation equipment. The nozzle comprises a ground covering mechanism and a spray irrigation mechanism, wherein the spray irrigation mechanism comprises a water inlet pipe, a rotating platform, a plurality of connecting columns and a spinning nozzle; the spinning nozzle comprises a plurality of arc pipelines and taper baffles; longitudinal arc openings are formed in the side walls of the arc pipelines, so that a cavity of each arc pipeline forms an open flow passage; the bottoms of the arc pipelines are connected with one another in a closed way, so as to form a taper bottom of the spinning nozzle; a longitudinal jet hole is formed in the taper bottom; the tops of the arc pipelines are divergent outward from the taper bottom along the radial direction; a taper baffle is connected with a position between the end parts of the side walls of each two adjacent arc pipelines. Each arc pipeline is warped for a preset angle in the same direction. The rotating platform is rotationally sleeved to the water inlet pipe; the plurality of connecting columns are fixed between the rotating platform and the taper baffles; the longitudinal jet hole is opposite to the upper pipe orifice of the water inlet pipe; the water inlet pipe is connected with an underground water inlet pipeline through the ground covering mechanism. The nozzle can increase the range under low pressure.

Description

technical field [0001] The invention relates to the field of irrigation equipment, in particular to an open channel type rotary sprinkler which can be used for underground burial. Background technique [0002] Sprinkler irrigation technology is a high-efficiency water-saving irrigation technology for farmland. It can spray water evenly and reduce labor intensity. It is widely used in today's agricultural operations. In the prior art, a rotary nozzle is mostly used for sprinkling irrigation, and its spraying effect is of great significance to the efficiency of sprinkling irrigation. Therefore, it is necessary to provide a rotary nozzle. [0003] The prior art provides such a rotary spray head, which includes a nozzle, a connecting cylinder and a rotating shaft. The connecting cylinder is a hollow structure with an open lower part. Through the blind hole at the lower part, it is fitted on one end of the rotating shaft protruding from the upper end of the connecting cylinder....

AI Technical Summary

Problems solved by technology

[0005] The flow channel in the rotary spray head provided by the prior art is closed, so when the spray head reaches a certain range, a greater working pressure is required, resulting in high energy consumption. In addition, the closed flow channel is easy to cause blockage, which is not conducive to the overall Buried below the plow layer
