Two filter plates 5 are inserted into the rear top of the purified water tank 2, and the two filter plates 5 are spaced apart. The outer walls of the filter plates 5 are connected to the purified water tank. The inner wall of filter plate 2 is slidably snapped together. The top of filter plate 5 is fixedly connected to handle 6. The bottom of water tank 2 has water pipe 7. One end of water pipe 7 is fixedly connected to the bottom of water tank 2. The other end of water pipe 7 extends forward. Valve 8 is installed at the other end of water pipe 7. Irrigation pipe assembly is set at the other end of water pipe 7. The bottom of water tank 1 is fixedly connected to slag discharge pipe 13. Slag discharge pipe 13 extends to the left and right. The bottom of water tank 1 is inclined towards the middle on both the front and rear sides. The top of slag discharge pipe 13 is connected to water tank 1. Slag discharge mechanism is set inside slag discharge pipe 13.

[0019] The irrigation pipeline assembly includes a water distribution pipe 9, which extends to the left and right. The middle part of the water distribution pipe 9 is fixedly connected to the other end of the clean water pipe 7. Several water delivery pipes 10 are fixedly connected to the front and both ends of the water distribution pipe 9. The water delivery pipes 10 are evenly distributed to the left and right. Several irrigation nozzles 11 are fixedly connected to the bottom of the water delivery pipes 10. The irrigation nozzles 11 are evenly distributed to the front and back. Support legs 12 are fixedly connected to the bottom of the front and rear ends of the water delivery pipes 10.

[0020] The slag discharge mechanism includes a rotating shaft 15 located inside the slag discharge pipe 13. The left end of the rotating shaft 15 is rotatably connected to the left end of the slag discharge pipe 13, which is closed. The outer wall of the right end of the rotating shaft 15 is rotatably connected to the lower part of a fixed frame 14. The upper part of the fixed frame 14 is fixedly connected to the upper part of the inner wall of the right end of the slag discharge pipe 13. A reamer 16 is fixedly connected to the outer wall of the rotating shaft 15. The reamer 16 is helical, and its outer wall is slidably connected to the inner wall of the slag discharge pipe 13. The right end of the slag discharge pipe 13... A valve 17 is installed on the right end of the slag discharge pipe 13, which protrudes from the right side of the water tank 1. The left end of the rotating shaft 15 passes through the left side wall of the slag discharge pipe 13. A worm gear 18 is fixedly sleeved on the outer wall of the left end of the rotating shaft 15. The worm gear 18 is located on the left side of the slag discharge pipe 13. Below the worm gear 18 is a worm 19. The front and rear ends of the worm 19 are rotatably connected to two support plates 4 on one side, respectively. The worm 19 meshes with the worm gear 18. The rear end of the worm 19 passes through the support plate 4. The rear end of the worm 19 is fixedly connected to a crank handle 20.

[0021] Rainwater falls into the water collection tank 1. Because the top opening of the water collection tank 1 is flared, it can collect rainwater more effectively. After being filtered by two filter plates 5 spaced back to back in the water collection tank 1, the rainwater enters the clean water tank 2. The filter plates 5 slide against the inner wall of the clean water tank 2, and there is a handle 6 on the top, which makes it easy to remove the filter plates 5 for cleaning or replacement. Removing one filter plate 5 for cleaning does not affect filtration, while the other filter plate 5 continues to filter.

[0022] When the collected rainwater needs to be used for irrigation, the valve 8 installed at the other end of the water purification pipe 7 is opened. The rainwater in the water purification tank 2 enters the water distribution pipe 9 through the water purification pipe 7. The water distribution pipe 9 extends to the left and right, and its front side is fixedly connected to several water delivery pipes 10 that are evenly distributed to the left and right. The rainwater is sprayed out from several irrigation nozzles 11 that are evenly distributed to the front and back and fixedly connected to the bottom of the water delivery pipe 10 to irrigate the land. The bottom of the front and rear ends of the water delivery pipe 10 are fixedly connected to the support legs 12 to provide support.

[0023] The bottom of the water receiving tank 1 is inclined towards the center on both the front and rear sides, which facilitates the sedimentation of silt and other impurities in the rainwater to the bottom inner side of the water receiving tank 1. When cleaning the silt at the bottom inner side of the water receiving tank 1 regularly, first open valve 27, then turn the crank handle 20. The crank handle 20 drives the worm gear 19 to rotate. Since the worm gear 19 meshes with the worm wheel 18, the worm wheel 18 drives the rotating shaft 15 to rotate. A spiral-shaped reamer 16 is fixedly connected to the outer wall of the rotating shaft 15. The outer wall of the reamer 16 slides in fit with the inner wall of the slag discharge pipe 13. The rotation of the rotating shaft 15 drives the reamer 16 to rotate, discharging silt and other impurities from the right end of the slag discharge pipe 13.
