In the prior art, the refraction cone inside the refraction type sprinkling irrigation spray head is often symmetrically arranged, so that the sprinkling irrigation water quantity is uniform in a windless environment, but the sprinkling irrigation effect is affected in a windless environment.

Therefore, based on the prior art, the present inventors have studied and used the scientific principle in order to improve the above-mentioned defects, and finally have proposed an utility model which has a reasonable design and effectively improves the above-mentioned defects.

Firstly, the utility model proposes that the refraction cone of the spray head is arranged away from the central axis, so that uneven water distribution is caused, and the possibility that the water quantity can be regulated and controlled is provided. The utility model then also incorporates a anemoscope such that in windy conditions. The anemoscope can adjust the priority of water distribution through the rotating shaft according to different conditions of wind direction and wind force. Meanwhile, the windless condition is considered, after all, the water distribution is uneven due to the arrangement of the refraction cone deviating from the central shaft, and the spring is further introduced, so that the refraction cone is impacted by water pressure under the windless condition, and the refraction cone is driven to rotate, so that the situation of uneven water distribution under the windless condition is solved.

In combination with the above design, the present inventors have found that the efficiency of irrigation can be improved by arranging the refractive cone offset from the central axis and introducing a design of the anemoscope and the spring.

The spray head of the present utility model will be specifically described with reference to the drawings.

As shown in fig. 1, the exemplary embodiment is a refractive spray head, which comprises a pipe joint head 1, a bracket 2, a rotating shaft 3, a anemoscope 4 and a refractive cone 5.

The pipe joint head 1 is made of stainless steel materials, the lower end of the pipe joint head is provided with a water inlet hole, and is provided with internal threads, so that the pipe joint head can be connected with an external water pipe or other water inlet devices by utilizing the threads. The pipe joint head 1 upper end is the apopore, in order to make the rivers blowout after can have faster speed and certain play water dispersity, the apopore is big-end-up's toper structure and big-end-up's toper structure combine together, and filter screen 11 locates the position that above-mentioned two toper structures combine together, can prevent that the foreign matter from getting into, avoids the jam.

The bracket 2 is in a shape as shown in the figure, a through hole is formed in the middle of the upper part of the bracket, the lower end of the bracket is connected with the pipe joint, and the bracket can support partial structures except the pipe joint 1 in the spray head.

For convenience of subsequent description, a line where the connecting lines of the centers of the two bottom surfaces of the cylinder overlap may be defined as a central axis, and the water outlet hole in the pipe joint head 1 needs to be aligned with the central axis.

The diameter of the spring 31 is slightly larger than the diameter of the cylinder of the rotating shaft 3, and the spring is sleeved on the rotating shaft 3, and the upper end of the spring can be contacted with the bracket 2.

The refraction cone 4 is a cone with the height of 60mm and the radius of the bottom surface of 80mm, and water flow is sprayed on the cone and can be scattered into tiny liquid drops to be scattered on vegetation and soil to be sprayed. The refraction cone 4 is vertically connected with the bottom surface of the lower end of the rotating shaft 3, the central shaft does not penetrate through the circle center of the bottom surface of the refraction cone 4, the direction of an arrow in the drawing deviates from the circle center, the deviation distance between the central shaft and the circle center is 10mm-25mm, the rotating shaft 3 can drive the refraction cone 4 to rotate, the lower end of the spring 31 can be in contact with the refraction cone, the spring 31 can ensure that the refraction cone 4 and the support 2 cannot be extruded together by water flow, so that the friction force is overlarge, in this way, under windless or breeze weather, the torque formed by the thrust of the water flow sprayed in the tangential direction of the refraction cone 4 is larger than the torque of the wind direction instrument to the rotating shaft 3, and the refraction cone 4 makes uniform speed or low speed rotation movement, so that the flow sprayed in all directions can be basically equal.

The refraction cone 4 can also be in a pyramid, frustum, hemispherical and other shape structures capable of dispersing water flow, so that water flow sprayed out by the pipe joint head 1 can be dispersed in four directions under the action of the refraction cone 4, the angle of 360 degrees is covered, and the utilization efficiency and irrigation quality of the water flow are improved.

The wind cap 522 is disposed at the head end of the vane 51, and is used for fixing the counterweight 521. The main shaft 53 is a longitudinally arranged cylinder, a through hole is formed in the main shaft, and the fan post 52 passes through the through hole. The base 54 is used for carrying the anemoscope 5, and is disposed below the main shaft 53. The base 54 is connected to the rotation shaft 3, and when the anemoscope 5 is blown by wind, the thrust to the anemoscope 5 can be formed into a torque of the rotation shaft 3, so as to drive the refraction cone 4 to rotate.

Second embodiment

Meanwhile, a anemoscope is connected to the rotating shaft, so that the preferential direction of irrigation is the same as the wind direction. In practical applications, the following three situations may occur:

in windless or breeze weather, the torque formed by the thrust of the water flow in the tangential direction of the refraction cone is larger than the torque of the wind direction instrument to the rotating shaft, the refraction cone rotates at a constant speed or a low speed, and the sprinkling irrigation flow in all directions is basically equal.

In strong wind weather, the torque formed by the thrust of the water flow in the tangential direction of the refraction cone is smaller than the torque of the wind direction indicator to the rotating shaft, the refraction cone does not rotate basically, the preferential sprinkling direction is the same as the wind direction, and at the moment, the water is sprinkled in the upward wind direction.

In medium wind weather, the refraction cone makes variable speed rotation movement between the two conditions, and the time of stay in the wind direction position in the preferential sprinkling irrigation direction is longer. Therefore, more water can be sprayed in the windward direction, and the influence of wind power on the irrigation effect is relieved.

Finally, it should be noted that: it is apparent that the above examples are only illustrative of the present utility model and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
