[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a rice seedling planter watering device, comprising a water supply component, a pressure regulating power unit and a water sprinkling component. The water supply component provides water supply power to the water sprinkling component through the pressure regulating power unit, and the pressure regulating power unit controls the water sprinkling amount of the water sprinkling component by adjusting the water supply pressure during the water supply process.

[0005] Furthermore, it also includes a soil moisture detection device interlocked with the voltage regulating power unit, and the voltage regulating power unit adjusts the water supply pressure according to the soil moisture data detected by the soil moisture detection device to achieve watering volume control of the corresponding watering assembly.

[0006] Furthermore, the pressure regulating power unit is composed of a power pump and an automatic pressure regulating valve group, and the automatic pressure regulating valve group includes a first regulating valve, a water pressure detection device and a second regulating valve installed in sequence on the water outlet pipe of the power pump along the water outlet path. The first regulating valve remains in a normally open state, and the second regulating valve is used to adjust the water outlet pressure.

[0007] Furthermore, the water supply assembly is composed of a water supply pipe connected to the power pump and a filtering device installed at the water inlet end of the water supply pipe.

[0010] Beneficial effect: The utility model can provide reasonable water supply for rice seedlings according to soil dryness and wetness through the flexible combination of water supply components, pressure regulating power units and sprinkler components. When the soil moisture detection device detects that the soil moisture is insufficient, the interlocking pressure regulating power unit starts to supply water, which is then sprayed into the soil through the sprinkler component until the soil moisture requirement for rice seedlings is reached, thereby reducing the probability of manual intervention and improving the convenience and efficiency of water supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 2 It is a structural schematic diagram of the pressure regulating power unit and the sprinkler assembly. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1 As shown, a watering device for a rice seedling raising and sowing machine comprises a water supply component 1, a pressure regulating power unit 2 and a watering component 3. The water supply component 1 provides water supply power to the watering component 3 through the pressure regulating power unit 2, and the pressure regulating power unit 2 controls the watering amount of the watering component 3 by adjusting the water supply pressure during the water supply process. The utility model also includes a soil moisture detection device correspondingly interlocked with the pressure regulating power unit 2. The pressure regulating power unit 2 adjusts the water supply pressure according to the soil moisture data detected by the soil moisture detection device to achieve the corresponding watering amount control of the watering component 3. The utility model can reasonably supply water for rice seedling raising according to the dryness and wetness of the soil through the flexible combination of the water supply component 1, the pressure regulating power unit 2 and the watering component 3. When the soil moisture detection device detects that the soil moisture is insufficient, the interlocking pressure regulating power unit 2 starts to supply water, and then sprays it into the soil through the watering component 3 until the soil moisture requirement of the rice seedling raising is reached, thereby reducing the probability of manual intervention and improving the convenience and efficiency of water supply.

[0015] The soil moisture detection device can use a soil moisture sensor. In order to improve the accuracy of soil moisture detection and coverage uniformity, the soil can be divided into regions, and multiple soil moisture sensors are set in each region. The humidity detection data is sent back to the back-end system for processing and the average value is taken, which helps to improve accuracy.

[0016] As attached Figure 1 and attached Figure 2As shown, the pressure regulating power unit 2 is composed of a power pump 21 and an automatic pressure regulating valve group 22. The automatic pressure regulating valve group 22 includes a first regulating valve 22.1, a water pressure detection device 22.2 and a second regulating valve 22.3 which are sequentially installed on the water outlet pipe 21a of the power pump 21 along the water outlet path. The second regulating valve 22.3 is used to adjust the outlet water pressure. Among them, the power pump 21 is a water pump. The water pressure detection device 22.2 can use a water pressure sensor, which is responsible for water pressure detection. The first regulating valve 22.1 is a ball valve, which is mainly responsible for regulating the water supply switch. In order to protect the water pump and prevent the pressure in the water pump from being too high, the first regulating valve 22.1 remains in a normally open state. The second regulating valve 22.3 is a pressure regulating valve, which is mainly responsible for water pressure regulation. Water pressure regulation controls the amount of water sprayed. When the pressure regulating valve is open, the amount of water sprayed is about 760ml~1800ml (1200 trays / hour). When the pressure regulating valve is closed, the amount of water sprayed is about 240ml~720ml (1200 trays / hour).

[0017] As attached Figure 1 As shown, the water supply assembly 1 is composed of a water supply pipe 11 connected to a power pump 21 and a filter installed at the water inlet end of the water supply pipe 11. The filter is a filter that can reduce the probability of pipe blockage, reduce the probability of pipe cleaning, and protect the equipment structure.

[0018] As attached Figure 2 As shown, the watering assembly 3 is composed of a watering pipe 31 connected to the power pump 21 and a watering nozzle 12 installed at the outlet end of the water supply pipe 11. In order to save costs, the watering nozzle 12 is a normally open nozzle component.
