A lifting spraying mechanism 4 is jointly provided on the water-fertilizer mixing tank 3 and the movable frame 1. A stirring motor 5 is fixedly installed at the upper middle part of the water-fertilizer mixing tank 3. The output shaft of the stirring motor 5 is rotatably connected to the water-fertilizer mixing tank 3. Two symmetrically distributed stirring paddles 6 are fixedly connected to the output shaft of the stirring motor 5. A telescopic block 7 is slidably sleeved on the outer side of the vertical part of the left stirring paddle 6. A telescopic plate 8 is fixedly connected to the lower end of the telescopic block 7. The telescopic plate 8 is slidably connected to the horizontal part of the left stirring paddle 6. A scraper 9 is fixedly connected to the lower end of the telescopic plate 8. The scraper 9 contacts the inner wall of the water-fertilizer mixing tank 3. A connecting plate 10 is fixedly sleeved on the outer side of the telescopic plate 8. A spring 11 is provided on the outer side of the telescopic plate 8. A protective sleeve 12 is provided on the outer side of the spring 11.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 One end of the spring 11 is welded to the connecting plate 10, and the other end of the spring 11 is welded to the horizontal part of the left stirring paddle 6. The spring 11 can be used to tighten the connecting plate 10.

The protective sleeve 12 can protect the spring 11 and prevent the spring 11 from rusting.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The lifting and spraying mechanism 4 includes synchronous cylinders 40. Two evenly distributed synchronous cylinders 40 are fixedly installed on the upper end of the moving frame 1. The telescopic end of each synchronous cylinder 40 is slidably connected to the moving frame 1. A moving plate 41 is fixedly connected to the telescopic end of each synchronous cylinder 40. The moving plate 41 is slidably connected to the inner wall of the moving frame 1. A rotating pipe 42 is rotatably connected to the inner wall of the moving plate 41. An atomizing nozzle 43 is fixedly connected to the lower side of the rotating pipe 42. A limiting plate 44 is fixedly sleeved on the outer side of the rotating pipe 42. The limiting plate 44 is rotatably connected to the moving plate 41. The end of the conveying pipe of the water-fertilizer mixing tank 3 is fixedly... A delivery pump 45 is fixedly installed, a half gear 46 is fixedly sleeved on the outside of the rotating pipe 42, a forward and reverse motor 47 is fixedly installed on the end face of the left moving plate 41, a gear 48 is fixedly sleeved on the outside of the output shaft of the forward and reverse motor 47, the gear 48 meshes with the half gear 46, and two symmetrically distributed limiting plates 49 are fixedly connected to the notch of the half gear 46. Through the setting of the delivery pump 45, the atomizing nozzle 43 and other structures, water and fertilizer can be sprayed. Under the action of the forward and reverse motor 47, the half gear 46 and other structures, the atomizing nozzle 43 can rotate back and forth, improving the spraying efficiency of water and fertilizer.

[0024] Please see Figure 1 , Figure 2 , Figure 3 Multiple atomizing nozzles 43 are provided, and the multiple atomizing nozzles 43 are evenly distributed on the rotating tube 42. Through the setting of atomizing nozzles 43, water and fertilizer can be atomized and sprayed. A connecting hose is fixedly connected to the rear side of the delivery pump 45. The connecting hose is fixedly connected to the rotating tube 42. The setting of the connecting hose can ensure the normal delivery of water and fertilizer. A limit post 490 is fixedly connected to the end face of the left moving plate 41. The limit post 490 is located between two limit plates 49. Through the cooperation of the limit post 490 and the limit plate 49, the rotation of the half gear 46 can be limited.

[0025] Working principle: During use, fertilizer granules and water can be fed into the water-fertilizer mixing tank 3 through the feed inlet at the top. Driven by the stirring motor 5, the stirring paddle 6 can be rotated to stir and mix the water and fertilizer granules. When the stirring paddle 6 rotates, it can drive the telescopic plate 8 and telescopic block 7 to rotate, which in turn drives the scraper 9 to slide along the bottom of the inner side of the water-fertilizer mixing tank 3 to scrape the undissolved fertilizer granules accumulated at the bottom of the inner side of the water-fertilizer mixing tank 3, thereby accelerating the fusion efficiency of the fertilizer granules. Under the deformation of the spring 11, the scraper 9 can be pushed to always be in contact with the bottom of the inner side of the water-fertilizer mixing tank 3, avoiding the problem that the scraper 9 is difficult to scrape effectively after long-term wear.

[0026] Through the action of the delivery pump 45, connecting hose and other structures, water and fertilizer can be input into the rotating pipe 42. Under the action of the atomizing nozzle 43, the water and fertilizer are atomized and sprayed. When the synchronous cylinder 40 drives the telescopic end to move, it can drive the moving plate 41 to slide along the inner wall of the moving frame 1, thereby driving the rotating pipe 42, atomizing nozzle 43 and other components to move, and the position of the atomizing nozzle 43 can be adjusted adaptively.

[0027] When the output shaft is driven to rotate forward by the reversible motor 47, it drives the gear 48 to rotate. In the meshing relationship, it drives the half gear 46 to rotate, which in turn drives the rotating tube 42 to rotate. This causes the atomizing nozzle 43 to deflect forward. When the half gear 46 rotates, it drives the limiting plate 49 to rotate. When the upper limiting plate 49 contacts the limiting post 490, the reversible motor 47 drives the output shaft to rotate in the opposite direction. Similarly, the lower limiting plate 49 contacts the limiting post 490, ultimately causing the atomizing nozzle 43 to deflect backward. This cycle repeats, allowing the atomizing nozzle 43 to rotate back and forth, enabling large-scale and uniform spraying of water and fertilizer, thus improving the efficiency of topdressing operations.
