[0029] The water supply mechanism includes a water pump 32 fixedly connected to the upper end of the drive box 1, a water inlet pipe 33 fixedly connected between the water inlet of the water pump 32 and the collecting cylinder 30, a water outlet pipe 34 fixedly connected to the water outlet of the water pump 32, a water distribution pipe 35 fixedly connected to the upper end of the water outlet pipe 34, and a water distribution hose 36 fixedly connected between the water distribution pipe 35 and the water distribution hard pipe 15.

[0030] Multiple groups of mounting plates 37 are fixedly connected to the outer side of the drive box 1 , and mounting holes 38 are formed inside the multiple groups of mounting plates 37 .

[0031] Before using the present invention: According to the layout of the landscaping area, soil moisture sensors are evenly buried in the soil of different areas to ensure comprehensive monitoring of soil moisture; The drive box 1 is fixed to a suitable position through the mounting plate 37 and the mounting hole 38. The position can be inside the garden or on the maintenance vehicle, which can be selected according to the use requirements; Install the water level sensor at a suitable position in the collecting tube 30; Electrically connect the main control system to each module and component, and configure the wireless communication module so that it can communicate normally with the remote control terminal; After the device is started, the soil moisture monitoring module monitors the soil moisture in real time and transmits the data to the main control system; the water level sensor monitors the water level in the collection tube 30 in real time and transmits the data to the main control system; the main control system determines whether irrigation is needed based on the preset irrigation strategy and the received soil moisture data.

[0032] If irrigation is required, the main control system controls the corresponding water pumps to start according to the soil moisture conditions in different areas, and adjusts the flow, height and angle of the dust-proof sprinklers so that the sprinklers can spray irrigation at the appropriate flow and angle.

[0033] When it rains, rainwater passes through the curved filter screen 31 and enters the interior of the collection tube 30 for collection; When the main control system receives a command to irrigate the garden, the water pump 32 is started. The water pump 32 pumps the water collected in the collection cylinder 30 into the water distribution hard pipe 15 through the water outlet pipe 34, the water distribution pipe 35, and the water distribution hose 36. The impact force of the water flow squeezes the sliding shaft 23, and the sliding shaft 23 squeezes the second spring 25 to push the adjustment member 24 to the side away from the nozzle body 21. The adjustment member 24 drives the movable limit block 27 to move in the movable limit groove 26 toward the sliding shaft 23 through the hinged connecting rod 29. The baffle 28 is driven by the movable limit block 27 to move away from the outside of the spray hole 22, and the water flow is sprayed out from the spray hole 22. When the water flow disappears, under the action of the second spring 25 , the baffle 28 is placed outside the spray hole 22 to shield the spray hole 22 and prevent dust and other impurities from clogging the spray hole 22 .

[0034] At the same time, the motor 4 is started, and the motor 4 drives the rotating connecting member 6 to move by rotating the connecting plate 5. The rotating connecting member 6 drives the reciprocating member 7 to reciprocate. The reciprocating member 7 drives the rack 10 to reciprocate through the reciprocating connecting member 9. The rack 10 drives the outer cylinder 11 to perform cyclic reciprocating motion through the gear 12. The outer cylinder 11 drives the connecting plate 14 and the water distribution hard pipe 15 at its upper end to cyclically rotate forward and reverse through the inner shaft 13, thereby expanding the spray range. When the height of the spraying needs to be adjusted, the inner shaft 13 is pulled to adjust the height of the inner shaft 13 extending out of the outer cylinder 11 , and the inner shaft 13 and the outer cylinder 11 are limited by the limiting member 19 .

[0035] During the irrigation process, the main control system continuously monitors soil moisture and water level data, and adjusts irrigation parameters in real time according to actual conditions to ensure the accuracy and effectiveness of irrigation.

[0036] When the water level in the collection tube 30 is lower than the preset minimum water level threshold, the sound and light alarm emits a sound and light alarm signal, and the main control system sends a water shortage alarm message to the remote control terminal to remind the user to replenish water in time.

[0037] Users can also use the remote control terminal to view the operating status of the irrigation device in real time and remotely set and adjust irrigation parameters according to actual needs. Regularly inspect and maintain components such as soil moisture sensors, water level sensors, water pumps, and dust-proof nozzles to ensure their normal operation; regularly clean the filter, replace the filter and activated carbon adsorption layer to ensure rainwater filtration effectiveness; regularly update and maintain the software of the main control system to ensure the stability and accuracy of the intelligent control program.
