Fig. 1-3 is the schematic diagram of the embodiment of the present utility model, it should be noted that this accompanying drawing is only as an example, is not drawn according to the condition of equal scale, and should not be used as the actual claim protection scope of the present utility model constituting a restriction.

As shown in Figure 1 and Figure 2, in order to achieve the above purpose, the utility model has designed an agricultural sprinkler device, including a fixed base 1, a cylindrical body 2, and an umbrella cap 3. The base shown can adopt any conventional shape, as long as It is enough to ensure that the sprinkler can be fixed in the field. The cylindrical body 2 includes a water delivery pipe 4 and a casing 5. The casing 5 is a hollow structure and is arranged around the water delivery pipe 4. The water delivery pipe 4 and the casing 5 It can be metal or other hard materials; the bottom end of the water delivery pipe 4 is provided with a water pump 6, and the top is provided with a water spray head 7, and the housing 5 is provided with a motor 8, a control device 9, a power supply 10, and the water pump 6 It is electrically connected with the power supply 10 and the control device 9, the power supply 10 is provided to the motor 8, the control device 9, and the water pump 6; the water delivery pipe 4 is located at the axis of the cylindrical body 2, and the motor 8 is located below the water spray head 7, and It is engaged with the water spray head 7, for example, it may be a gear connection, and the motor provides power for the water spray head 7 to rotate. The cylindrical body 2 also includes a water inlet 11, the water inlet 11 passes through the shell 5 and communicates with the water delivery pipe 4, the water inlet 11 is connected with a water inlet pipe 12, and the water inlet pipe 12 connects with the water inlet pipe 12 from the cylindrical body 2. Extending outwards, a plurality of humidity sensors 13 are arranged at intervals along the outward extension direction of the water inlet pipe 12, and the humidity sensors 13 are buried with the water inlet pipe 12 to a certain depth below the surface, such as 5-20cm, and the corresponding position The humidity signal is transmitted to the control device 9 through the signal line attached to the outside of the water inlet pipe 12, the control device 9 generates a corresponding control signal according to the humidity signal, and the water pump 6 generates water pressure of different strengths according to the control signal. Water head 7 sprays out. As shown in Figure 2, the water spraying position is near position C, and when the humidity sensor 13 at this position detects that the humidity has reached a preset value, the humidity signal is fed back to the control device 9, and the control device 9 generates a control signal , control the water pump 6 to weaken the water spray pressure. At this time, the water spray position can be switched from position C to position B. Similarly, when the humidity of position C reaches the preset value, the water spray position can be switched from position B to position A, when the humidity at position A reaches the preset value, the control device 9 controls the water spray pipe to close, and stops water spraying until the humidity sensor 13 at position C detects that the humidity has dropped to a certain value below the preset value again, and starts to spray water again , in this cycle, to achieve the purpose of automatic water spraying according to soil humidity.
