The utility model discloses a rotary structure of a water-saving high-pressure spray head for farm irrigation, which comprises a base, wherein a fixing box is fixedly connected to the upper surface of the base, a rotary column is rotatably connected to the inner bottom wall of the fixing box, a plurality of guide vanes are fixedly connected to the surface of the rotary column, a fixing pipe is embedded in the upper surface of the fixing box, a rotary sleeve is rotatably connected to the surface of the fixing pipe through a waterproof sealing bearing, three extension pipes are embedded in the surface of the rotary sleeve, a spray head pipe is sleeved at one end of the extension pipe far away from the rotary sleeve, and three nozzles are arranged on the surface of the spray head pipe.

The prior art solutions described above have the following drawbacks: the impact force of water flow is adopted to drive the guide vane to rotate, and then the rotating column and the rotating sleeve are driven to rotate, so that automatic rotation of the spray head is realized, but when the condition of slower water flow velocity is met, the problems that the spray head is low in rotating speed and small in irrigation area can occur. And the rotating speed can be controlled only through the water flow rate, and the nozzle cannot be driven to rotate under the condition of small water flow rate due to the problem of starting inertia, so that the water flow rate control device is not suitable for small-area irrigation.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a sprinkler head capable of controlling irrigation area, simple in structural arrangement and low in cost and capable of rotating and regulating speed.

In order to achieve the purpose, the rotatable speed-adjustable sprinkler head comprises a plurality of inner pipes connected to the sprinkler, wherein water outlets are formed in the inner pipes, outer pipes are sleeved on the inner pipes, a plurality of water outlet structures are arranged on the outer pipes, and when the outer pipes are rotated to align the water outlet structures with the water outlets, the sprinkler head sprays water flow. The structure is characterized in that different water outlet structures on the outer tube can be rotated to positions corresponding to the water outlets according to requirements, so that the rotating speed of the sprinkler can be regulated, and the irrigation area of the sprinkler can be controlled.

In order to realize the jet velocity of different rivers, be equipped with a plurality of water outlet on the play water structure, the play water structure's on the same outer tube play water spout quantity all is different but the aperture is unanimous. When the apertures are consistent, the water outlet nozzles are fewer, the water body spraying speed is higher, the sprinkler rotates faster, and the irrigation area is larger.

In order to realize the jet velocity of different rivers, be equipped with a plurality of water outlet on the water outlet structure, the water outlet of the water outlet structure on same outer tube quantity is unanimous but the aperture is different. When the number of the water outlet nozzles is consistent, the smaller the aperture, the faster the water body spraying speed, the faster the sprinkler rotates, and the larger the irrigation area.

In order to fix the outer tube on the inner tube, a circle of concave ring is arranged on the inner tube in the direction away from the sprinkler, and the outer tube is in interference fit with the inner tube; the inner wall of the water outlet structure is provided with a fixing protrusion, and the fixing protrusion is matched with the concave ring for limiting. The fixing bulges are clamped into the concave rings, so that the axial positions of the outer tube and the inner tube can be determined under the condition that the rotation of the outer tube is not influenced, the situation that the outer tube is tired to release due to the cooperation between the outer tube and the inner tube after the outer tube rotates for many times is avoided, and the axial impact force caused by water flow can be effectively resisted.

In order to seal water leakage, the outer ring of the water outlet is provided with a circle of groove, the water outlet structure is arranged in the groove, and a waterproof rubber ring is arranged between the groove and the water outlet structure. The waterproof rubber ring is arranged between the water outlet and the water outlet nozzle, and is in interference fit connection, so that the water leakage of the sprinkler nozzle can be effectively prevented.

In order to clearly identify the maximum flow rate and the minimum flow rate, the outer tube is provided with scales on one side close to the sprinkler, and the scales correspond to marks on the sprinkler pipeline. Corresponding to the identification on the sprinkler, it is clear what flow rate is now in.

Meanwhile, the utility model provides a sprinkler, which comprises the sprinkler nozzle with the rotatable speed regulation function. The sprinkler is characterized in that different water outlet structures on the outer tube can be rotated to positions corresponding to water outlets according to requirements to adjust the rotating speed of the sprinkler, so that the irrigation area of the sprinkler is controlled.

Compared with the prior art, the utility model can rotate the outer pipe to regulate the water jet speed, when the water flow speed is low, the outer pipe can be rotated to the surface with the minimum water outlet nozzle number, so that the water jet speed is increased, and the rotation speed of the sprinkler is increased, thus irrigation can be performed when the water flow is low. When the required irrigation area is smaller, the spray head can be rotated to the surface with the largest number of water outlet spray heads, and the rotation speed of the sprinkler is low and the spraying area is small.
