Compared with prior art, the utility model has the advantages that：

The utility model by humidity sensor detect air humidity, by moisture transducer detect farmland humidity and The aridity in farmland is detected by temperature sensor, controls supply-water pump to irrigate farmland when three is in exception, when Parameter normally stops irrigating afterwards so that rationally, crop obtains good humidity environment for field irrigation.

Brief description of the drawings

Fig. 1 is the schematic diagram according to the utility model farmland automatic irrigation device.

Main Reference Numerals explanation：

1- water tanks, 2,5- non-return valves, 3- supply-water pumps, 4- pressurized tanks, 6- rotary nozzles.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain is not limited by specific embodiment.

Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units Part or other parts.

Fig. 1 shows the structural representation of the farmland automatic irrigation device according to the utility model preferred embodiment.

As shown in figure 1, farmland automatic irrigation device includes：Water tank 1, rotary nozzle 6, humidity sensor, moisture sensing Device, temperature sensor, first contactor KM1, second contactor KM2, the 3rd contactor KM3, the 4th contactor KM4 start normal Switch SB1, the 5th contactor KM5, the 6th contactor KM6 and the 7th contactor KM7.

With continued reference to Fig. 1, multiple rotary nozzles 6 are distributed in farmland, for irrigating farmland, water tank 1 Outlet pipeline passes sequentially through supply-water pump 3, pressurized tank 4 and is connected with multiple rotary nozzles 6 respectively；Set between water tank 1 and supply-water pump 3 There is non-return valve 2, non-return valve 5 is provided between supply-water pump 3 and rotary nozzle 6；Humidity sensor, moisture transducer and temperature sensor It is respectively arranged in farmland, is respectively used to the aridity of the humidity, the humidity of agricultural land soil and agricultural land soil of acquisition farm environment；Open Dynamic normal open switch SB1 and first contactor KM1 in parallel, second contactor KM2, the 3rd contactor KM3 and the 4th contactor KM4 Coil series connection access AC power, wherein, the first normally opened end KM1-1 of first contactor KM1 with start normal open switch SB1 simultaneously Connection；The normally opened end KM2-1 series connection of the coil of the 5th contactor KM5, the normally opened end SB2 of humidity sensor and second contactor KM2 Incoming transport power supply；The coil of the 6th contactor KM6, the normally opened end SB3 of moisture transducer and the normally opened end of the 3rd contactor KM3 KM3-1 series connection accesses AC power；The coil of the 7th contactor KM7, the normally opened end SB4 of temperature sensor and the 4th contactor The normally opened end KM4-1 series connection of KM4 accesses AC power；Wherein, three power connection ends of supply-water pump 3 pass through the 5th contactor respectively Normally opened end KM5-1, the normally opened end KM6-1 of the 6th contactor and the 7th contactor normally opened end KM7-1 access three-phase alternating current Source, indicator lamp HL1 end KM1-2s normally opened with the second of first contactor connects and accesses AC power.
