[0002] The integrated water and fertilizer mixing machine is a modern agricultural device that combines irrigation and fertilization. Through precise mixing and efficient delivery, it achieves the scientific application of water and fertilizer. Its core functions lie in mixing and delivery. The mixing machine delivers the prepared fertilizer solution directly to the crop roots through a conduit system, reducing nutrient loss and volatilization in the soil and significantly improving fertilizer utilization. Compared to traditional manual fertilization, the integrated water and fertilizer mixing machine not only saves labor but also reduces resource waste and increases crop yield and quality, making it an important tool in modern precision agriculture.
[0003] Most current water-fertilizer mixing machines use a vertical shaft design for their mixing devices, which can only create eddies in the upper layer of the liquid. This has almost no disturbance to the high-density sediments at the bottom (such as phosphate crystals and organic fertilizer fibers), resulting in low fertilizer utilization. Moreover, fertilizer accumulates on the bottom plate of the tank and hardens into lumps. Manual cleaning requires stopping the machine for disassembly, which reduces work efficiency. Therefore, a water-fertilizer mixing device that is easy to adjust is proposed. Utility Model Content

[0027] Example
[0028] In the current technology, most water-fertilizer mixing machines use a vertical axis design for their mixing devices, which can only form eddies in the upper layer of the liquid. They have almost no disturbance to the high-density sediments at the bottom (such as phosphate crystals and organic fertilizer fibers), resulting in low fertilizer utilization. Moreover, fertilizer accumulates on the bottom plate of the tank for a long time and forms hard lumps. Manual cleaning requires stopping the machine for disassembly, which reduces work efficiency.

The three bottles 31 are connected to the fertilizer tank 1 through the first pipes 32, and the three bottles 31 are connected to the mixing tank 2 through the second pipes 34. The tops of the bottles 31 and the mixing tank 2 are connected to air holes. The bottom of the first pipe 32 is 2cm-4cm away from the bottom wall of the bottle 31. A first gate valve 35 is installed on the outside of the first pipe 32, and a second gate valve 36 is installed on the outside of the second pipe 34. A scale 33 is provided on the outside of the three bottles 31.
[0031] The mixing assembly 4 includes a motor 41, a first rotating shaft 42, a rotating frame 43, a first scraper 45, and a support frame 46. The support frame 46 is fixedly connected to the inside of the fertilizer tank 1 and the mixing tank 2. The motor 41 is fixedly connected to the rotating frame 43 through the first rotating shaft 42. Several mixing rollers 44 are fixedly connected to the inner wall of the rotating frame 43. The outer side of the rotating frame 43 is fixedly connected to the first scraper 45. The outer side of the first scraper 45 is in elastic contact with the inner wall of the fertilizer tank 1 and the mixing tank 2. When the rotating frame 43 rotates, it drives the first scraper 45 to scrape and clean the inner wall of the fertilizer tank 1 and the mixing tank 2. The mixing rollers 44 stir the inside of the fertilizer tank 1 and the mixing tank 2.
[0032] The anti-sedimentation component 5 includes a cylinder 51, a second rotating shaft 52, and a U-shaped frame 55. The piston rod of the cylinder 51 is fixedly connected to a rack 54. One end of the second rotating shaft 52 is fixedly connected to a gear 53 that meshes with the rack 54. The U-shaped frame 55 is fixedly sleeved on the outside of the second rotating shaft 52. A second scraper 56 is fixedly connected to the outside of the U-shaped frame 55. The outer wall of the second scraper 56 is in elastic contact with the inner wall of the fertilizer tank 1 and the mixing tank 2. The second rotating shaft 52 is rotatably connected to the inside of the fertilizer tank 1 and the mixing tank 2 through a bearing. When the second rotating shaft 52 rotates, it drives the second scraper 56 to rotate through the U-shaped frame 55, stirring and breaking up the material accumulated on the bottom wall of the fertilizer tank 1 and the mixing tank 2. A box 9 is fixedly connected to the outside of each of the three fertilizer tanks 1 and the mixing tank 2. The cylinder 51 is fixedly installed on one side of the box 9. A guide rail adapted to the rack 54 is fixedly connected to the bottom wall of the box 9. The rack 54 moves back and forth inside the box 9 through the guide rail.
[0033] The working principle or structural principle is as follows: various fertilizers and water are injected into three fertilizer tanks 1 through the feed pipe 8. The motor 41 of the stirring assembly 4 drives the rotating frame 43 to rotate through the first rotating shaft 42. The stirring roller 44 of the rotating frame 43 stirs the liquid in the fertilizer tank 1. During this process, the cylinder 51 drives the rack 54 to move. The rack 54 drives the second rotating shaft 52 to rotate through the meshing gear 53, which drives the U-shaped frame 55 to rotate inside the fertilizer tank 1. The second scraper 56 on the outside of the U-shaped frame 55 scrapes off the material accumulated on the bottom wall of the fertilizer tank 1 to prevent fertilizer from accumulating at the bottom of the tank.
[0034] Activate the first gate valve 35 and the second gate valve 36. The three types of fertilizer solutions, after being stirred, are injected into the mixing tank 2 through the first pipe 32. The fertilizer solution in the fertilizer tank 1 is first injected into the bottle 31 along the first pipe 32. The bottle 31 is equipped with a scale 33. The amount of fertilizer solution in the bottle 31 is controlled according to the scale 33. For example, if the ratio is 1:2:1, the first gate valve 35 is closed when the fertilizer solution in the bottle 31 at the first and third fertilizer tanks 1 overflows to the first scale line, and the first gate valve 35 is closed when the fertilizer solution in the bottle 31 at the second fertilizer tank 1 overflows to the second scale line. At this time, the ratio of the liquids in the three fertilizer tanks 1 injected into the bottle 31 is 1:2:1, which completes the rapid adjustment of the water-fertilizer ratio. The water pressure in the bottle 31 injects the fertilizer solution in the bottle into the mixing tank 2. Close the second gate valve 36. After being stirred and mixed by the stirring component 4, the water-fertilizer mixture is discharged through the discharge pipe 7.
[0035] In summary, various fertilizers and water are injected into three fertilizer tanks 1. The rotating frame 43 of the stirring component 4 drives the stirring roller 44 to stir the liquid in the fertilizer tank 1. During this process, the cylinder 51 of the anti-sedimentation component 5 drives the rack 54 to move. The rack 54 drives the U-shaped frame 55 to rotate inside the fertilizer tank 1 through the meshing gear 53, scraping off the material accumulated on the bottom wall of the fertilizer tank 1, preventing fertilizer from accumulating at the bottom of the tank and improving work efficiency. The three types of fertilizer liquid after stirring are injected into the mixing tank 2 through the first pipe 32 and the second pipe 34. As needed, the adjusting component 3 is driven to inject the fertilizer liquid in the three fertilizer tanks 1 into the bottle 31 according to the ratio, and then inject the fertilizer liquid in the bottle 31 into the mixing tank 2 to complete the rapid adjustment of the water-fertilizer ratio. The first scraper 45, the second scraper 56, the gear 53, and the rack 54 are regularly inspected, maintained, and replaced. In this embodiment, the motor 41 is a model 110SJT-M040D manufactured by Guangzhou CNC System Parts Center. The first gate valve 35 and the second gate valve 36 are both model LEPZ941HX-16DN50100 manufactured by Tianjin Zhansheng Valve Manufacturing Plant. Since the structure and operating principle of this model are existing technologies, their structure and operating principle will not be described in detail here. The cylinder 51 is a double-acting cylinder. The cylinder 51 pushes the rack 54 to move one circuit, driving the gear 53 to rotate 180-200 degrees. Sealing gaskets are provided at the contact points between the first rotating shaft 42, the second rotating shaft 52, and the tank body to prevent water leakage.
