[0045] The rainwater collecting assembly 5 includes a rainwater collecting trough 501 fixedly mounted on the supporting vehicle body 1 and extending at one end into the water storage tank 2. The end of the rainwater collecting trough 501 extending outside the water storage tank 2 is tilted upward, and a rainwater collecting tank 502 for collecting rainwater is fixedly mounted thereon. The rainwater collecting tank 502 is provided with a rainwater filter plate 5021 for filtering out impurities in the rainwater. The rainwater filter plate 5021 is also provided with a rainwater drainage pipe 5022 corresponding to the rainwater collecting trough 501. The rainwater collecting tank 502 can filter out impurities in the rainwater through the rainwater filter plate 5021, collect rainwater, and transport the filtered rainwater to the rainwater collecting trough 501 through the rainwater drainage pipe 5022.

[0046] A discharge port 5011 for discharging leaves is provided on the rainwater collecting trough 501 and below the rainwater collecting tank 502. The discharge port 5011 is fixedly installed with a guide rail 5012 for limiting the sliding of the cleaning slider 7. The discharge port 5011 is used to discharge impurities such as leaves in the rainwater collecting trough 501, and the guide rail 5012 is used to guide the cleaning slider 7 to move linearly in the rainwater collecting trough 501.

[0047] The driving assembly 6 includes a dual-axis motor 601 fixedly mounted on the water tank 2, the output shaft of the dual-axis motor 601 extending to the outside of the water tank 2 is connected to a rotating wheel 602, the rotating wheel 602 is hingedly connected to a connecting rod 603, the output shaft of the dual-axis motor 601 away from the rotating wheel 602 is connected to a stirring rod 604, one end of the stirring rod 604 extends into the water tank 2, the dual-axis motor 601 can drive the rotating wheel 602 and the stirring rod 604 to rotate, and is used to drive the cleaning slider 7 to slide in the rainwater collection tank 501 and stir the water and added reagents in the stirring tank.

[0048] A rubber scraper 701 is provided at one end of the cleaning slider 7 located in the rainwater collecting trough 501. The end of the rubber scraper 701 away from the rubber scraper 701 is connected to the end of the connecting rod 603 away from the rotor 602 through a protruding shaft 702. The cleaning slider 7 is also provided with an arc-shaped cavity 703 adapted to the water storage tank 2. The cleaning slider 7 is also provided with a linearly arranged drainage groove 704. The rubber scraper 701 is elastic and can maintain full contact with the rainwater collecting trough 501 when moving in the inclined rainwater collecting trough 501. The power of the connecting rod 603 is transmitted to the cleaning slider 7 through the protruding shaft 702, so that the cleaning slider 7 can make horizontal reciprocating motion in the rainwater collecting trough 501, discharge the leaves in the rainwater collecting trough 501 through the slag discharge port 5011, and fit with the water storage tank 2 through the arc cavity 703 when not moving, and further filter the rainwater in the rainwater collecting trough 501 through the drainage groove 704.

[0049] During use, the device can be moved and positioned between different terrains through the moving wheels that support the vehicle body 1, and the device can be moved outdoors to facilitate rainwater collection. When it rains, rainwater first flows into the rainwater collection tank 502, and is filtered through the rainwater filter plate 5021 to remove impurities. The purified rainwater flows into the rainwater collection trough 501 through the rain pipe 5022. The inclined structure of the rainwater collection trough 501 can better guide the rainwater to the water storage tank 2 for storage. In this process, larger debris such as leaves will easily enter the exposed rainwater collection trough 501. After the rainwater is collected, the dual-axis motor 601 is started, and its output shaft extending to the outside of the water storage tank 2 drives the runner 602 to rotate. The runner 602 is connected to the cleaning slider 7 on the protruding shaft 702 through the connecting rod 603, and slides back and forth linearly in the guide rail 5012 in the rainwater collection trough 501 to clean the rainwater. The rubber scraper 701 on the slider 7 is always in contact with the bottom of the rainwater collecting trough 501, scraping off debris such as leaves in the rainwater collecting trough 501, and the scraped debris is discharged through the slag discharge port 5011. When the cleaning slider 7 is not moving, it is attached to the water storage tank 2 through the arc cavity 703, and the rainwater in the rainwater collecting trough 501 is further filtered through the drain trough 704. When the irrigation water needs to be treated with chemicals, chemicals are added to the water storage tank 2 through the chemical adding hopper 201 on the water storage tank 2. The chemicals are mixed with the rainwater in the water storage tank 2 to achieve specific irrigation effects, such as fertilization, pest control, etc. After the chemicals are added, the dual-axis motor 601 is started to drive the stirring rod 604 to rotate, stirring the rainwater and chemicals in the water storage tank 2, so that the chemicals and rainwater are fully and evenly mixed, ensuring that the concentration of chemicals in the irrigation water is uniform and consistent, thereby improving the irrigation effect.

[0050] During the long-term rainwater collection process, impurities in the water tank 2 will gradually accumulate and form sewage. When cleaning is required, the sewage outlet 202 on the water tank 2 is opened to discharge the precipitated impurities and sewage to keep the water tank 2 clean and prevent impurities from clogging the pipe or affecting the irrigation effect. The water in the water tank 2 is transported to the conversion nozzle 404 through the water supply port 203 and the first liquid pump 2031 through the water hose 2032. When sprinkling irrigation is required, the sprinkling motor 402 is started, and its output shaft drives the U-shaped bracket 4021 to rotate. The U-shaped bracket 4021 is connected to the switching nozzle 404 through the hinge shaft. 4022 drives the conversion nozzle 404 to deflect toward the sprinkler interface 302, connecting the conversion nozzle 404 to the sprinkler interface 302. At this time, the water delivered to the conversion nozzle 404 through the water supply hose 2032 enters the sprinkler water inlet pipe 3021 through the sprinkler interface 302 and flows into the water collection bucket 301. The second liquid pump 3013 is started, and the water in the water collection bucket 301 is pumped out through the sprinkler diversion pipe 3014 and sprayed upward from the sprinkler nozzle 3015, completing the sprinkler irrigation operation. During this process, the diversion valve pipe 3012 connected to the water storage tank 2 is in a closed state.

[0051] When drip irrigation is required, the drip irrigation motor 403 is started, and its output shaft drives the first swing arm 4031 to rotate. The first swing arm 4031 drives the conversion nozzle 404 to deflect toward the drip irrigation interface 303 through the second swing arm 4032, so that the conversion nozzle 404 is connected to the drip irrigation interface 303. At this time, water delivered to the conversion nozzle 404 by the water supply hose 2032 enters the drip irrigation diversion pipe 3031 through the drip irrigation interface 303. The water in the drip irrigation diversion pipe 3031 drips out through the drip irrigation nozzle 3032, realizing the drip irrigation operation. Since the water supply hose 2032 connected to the conversion nozzle 404 is flexible, it will not interfere with the deflection of the conversion nozzle 404.

[0052] A method for a water-saving irrigation device with rainwater collection comprises the following steps:

[0053] Step 1: Move the device to a suitable outdoor location via the moving wheels supporting the vehicle body 1. After the rainwater is filtered through the rainwater collection tank 502 and the rainwater filter plate 5021, it flows into the rainwater collection trough 501 through the rainwater drain pipe 5022 and is guided to the water storage tank 2 for storage.

[0054] Step 2: After rainwater collection is completed, start the dual-axis motor 601, and drive the cleaning slider 7 to slide back and forth in the rainwater collection trough 501 through the wheel 602 and the connecting rod 603. The rubber scraper 701 scrapes off the debris, and the debris is discharged from the slag discharge port 5011. The arc cavity 703 of the cleaning slider 7 fits with the water storage tank 2, and the drain trough 704 further filters the rainwater.

[0055] Step three: add medicine to the water storage tank 2 through the medicine adding hopper 201, start the stirring rod 604 of the dual-axis motor 601 to stir the rainwater and medicine to make them evenly mixed, and open the valve on the drainage valve pipe 3012.

[0056] Step 4: Water is transported to the conversion nozzle 404 through the water supply port 203, the first liquid pump 2031 and the water supply hose 2032, the sprinkler motor 402 is started, and the conversion nozzle 404 is driven to connect with the sprinkler interface 302. The water flows into the water collection bucket 301 through the sprinkler inlet pipe 3021, the second liquid pump 3013 is started, and water is sprayed out from the sprinkler nozzle 3015 to realize the sprinkler operation.

[0057] Step 5: Start the drip irrigation motor 403 to drive the conversion nozzle 404 to connect with the drip irrigation interface 303. Water flows into the drip irrigation nozzle 3032 through the drip irrigation diversion pipe 3031 and drips out, thus realizing the drip irrigation operation.
