Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an automatic fertilizer application device integrating water and fertilizer. Background Technology

[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. It uses a pressure system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of different crop types. The fertilizer solution is then mixed with irrigation water and supplied through a controllable pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly, regularly, and quantitatively irrigate the crop root development and growth area.

[0003] In existing technologies, when solid fertilizer and water are mixed, the solid fertilizer is usually poured directly into the water and stirred. Even with stirring, it still takes a certain amount of time for the solid fertilizer to blend with the water.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] refer to Figure 1-4 The present invention provides an integrated water and fertilizer automatic fertilizer application device, including a tank 1. A water storage tank 2, a liquid fertilizer storage tank 3 and a solid fertilizer storage tank 4 are fixedly connected to the top of the tank 1. The bottom ends of the water storage tank 2, the liquid fertilizer storage tank 3 and the solid fertilizer storage tank 4 are all fixedly connected to one end of a first conveying pipe 5. A crushing and cleaning component is provided inside the solid fertilizer storage tank 4. The crushing and cleaning component and the first conveying pipe 5 on the solid fertilizer storage tank 4 are correspondingly arranged.

[0028] A second conveying pipe 6 is fixedly connected to the middle of the top of the tank body 1. The other end of the first conveying pipe 5 is fixedly connected to the top of the second conveying pipe 6. The bottom end of the second conveying pipe 6 extends into the tank body 1 and is equipped with a stirring assembly. The stirring assembly is correspondingly arranged with the bottom end of the second conveying pipe 6. A driving component is provided on the tank body 1, and the stirring assembly and the driving component are connected by transmission.

[0029] Water storage tank 2, liquid fertilizer storage tank 3, and solid fertilizer storage tank 4 are used to store water, liquid fertilizer, and solid fertilizer, respectively. The solid fertilizer storage tank 4 is equipped with a pulverizing and cleaning component to pulverize the solid fertilizer, ensuring the mixing efficiency of water and solid fertilizer, and preventing a large amount of solid fertilizer from sticking to the tank 1 after contact with water. Specifically, the three first conveying pipes 5 are all connected to the second conveying pipes 6, ensuring that the water washes and cleans the conveying pipes when water and fertilizer are added. At the same time, water and fertilizer are mixed and conveyed to the tank 1 simultaneously. When the stirring component is used to stir later, it further ensures the uniformity and mixing efficiency of water and fertilizer after mixing, while reducing the situation where the pulverized solid fertilizer powder floats on the water surface, thus ensuring the water and fertilizer mixing effect.

[0030] The scheme is further optimized. The crushing and cleaning component includes two first rotating shafts 7 and two second rotating shafts 8 rotatably connected to the opposite side walls of the solid fertilizer storage box 4. The first rotating shaft 7 is located directly above the second rotating shaft 8. A crushing roller 9 is fixedly connected to the first rotating shaft 7. The two crushing rollers 9 are correspondingly arranged and are both correspondingly arranged to the first conveying pipe 5 on the solid fertilizer storage box 4. A cleaning roller 10 is fixedly connected to the second rotating shaft 8. The two cleaning rollers 10 are respectively corresponding to the two crushing rollers 9. A control component is provided on the outer wall of the solid fertilizer storage box 4. The first rotating shaft 7 and the second rotating shaft 8 are respectively connected to the control component for transmission.

[0031] Both ends of the first rotating shaft 7 and the second rotating shaft 8 are rotatably connected to the inner wall of the solid fertilizer storage box 4 through bearings to ensure stable rotation. The two crushing rollers 9 rotate relative to each other to crush the solid fertilizer, ensuring the efficiency of water-fertilizer mixing in the later stage, while preventing the solid fertilizer from sticking to the inside of the tank 1.

[0032] The scheme is further optimized. The control components include two first gears 11, which mesh with each other. One end of each of the two first rotating shafts 7 and the two second rotating shafts 8 on the same side extends out of the solid fertilizer storage box 4. The extended end of the first rotating shaft 7 is fixedly connected to the first gear 11. The extended end of the second rotating shaft 8 is fixedly connected to the first sprocket 12. The end of the first gear 11 away from the solid fertilizer storage box 4 is coaxially fixedly connected to the second sprocket 13. The first sprocket 12 and the second sprocket 13 on the same axis are connected by a chain 36. A first motor 14 is fixedly connected to the solid fertilizer storage box 4. The end of any first rotating shaft 7 away from the second sprocket 13 extends out of the solid fertilizer storage box 4 and is fixedly connected to the output shaft of the first motor 14.

[0033] The first motor 14 drives the first rotating shaft 7 to rotate. The two meshing first gears 11 on the two first rotating shafts 7 drive the crushing roller 9 to rotate relative to each other to crush the solid fertilizer. At the same time, the first rotating shaft 7 drives the cleaning roller 10 to rotate through the first sprocket 12, the second sprocket 13 and the chain 36 to clean the powdery fertilizer adhering to the crushing roller 9 and ensure crushing efficiency. Specifically, several cleaning brushes are fixedly connected to the outer wall of the crushing roller cleaning roller 10 to ensure cleaning effect.

[0034] The scheme is further optimized. The stirring assembly includes a first bevel gear 15 rotatably connected to the second conveying pipe 6. A support ring 16 is fixedly connected to the bottom end of the first bevel gear 15. A second gear 17 is fixedly connected to the outer wall of the support ring 16. An annular toothed plate 18 is fixedly connected to the inner wall of the tank 1. Several third gears 19 are arranged at equal intervals along the circumference between the annular toothed plate 18 and the second gear 17. The annular toothed plate 18 and the second gear 17 respectively mesh with the third gears 19. One end of the stirring shaft 20 is fixedly connected to the middle of the bottom end of the third gear 19. A tilting stirring assembly is provided on any stirring shaft 20. The tilting stirring assembly is correspondingly arranged with the second conveying pipe 6. The first bevel gear 15 is connected to the driving component for transmission.

[0035] The support ring 16 is sleeved on the second conveying pipe 6. When the first bevel gear 15 rotates, it drives the support ring 16 to rotate synchronously. When the support ring 16 rotates, it drives the second gear 17 to rotate. The inner side wall of the annular toothed plate 18 is provided with tooth grooves. The third gear 19 meshes with the tooth grooves and the second gear 17. When the second gear 17 rotates, it drives the third gear 19 to rotate on the annular toothed plate 18, realizing the rotation and revolution of the third gear 19, thereby driving the stirring shaft 20 to rotate and revolve, ensuring the full mixing of water and fertilizer.

[0036] The scheme is further optimized. The flipping stirring assembly includes a first support plate 21 with one end sleeved on the stirring shaft 20. The other end of the first support plate 21 is fixedly connected to the outer wall of the support ring 16. The first support plate 21 is located below the third gear 19. A second support plate 22 is fixedly connected to the bottom end of the first support plate 21. A first connecting rod 23 is rotatably connected to the second support plate 22. A second bevel gear 24 is fixedly connected to the other end of the first connecting rod 23. A third bevel gear 25 is fixedly connected to the bottom end of the outer wall of the second conveying pipe 6. The third bevel gear 25 meshes with the second bevel gear 24. A flipping plate is provided on the second bevel gear 24. The flipping plate is located below the second conveying pipe 6.

[0037] The first support plate 21 and the second support plate 22 follow the support ring 16 and the stirring shaft 20 to make circular motion synchronously. When the second support plate 22 makes circular motion, it drives the second bevel gear 24 to roll on the third bevel gear 25. The second bevel gear 24 also rotates on its own axis while making circular motion around the central axis inside the tank 1, thereby driving the revolution and rotation of the flipping plate, so as to fully stir and mix the fertilizer and water floating on the liquid, and prevent the fertilizer from floating on the liquid surface.

[0038] The scheme is further optimized so that the flipping plate includes a number of stirring plates 26 fixedly connected to the end of the second bevel gear 24 away from the first connecting rod 23, and the number of stirring plates 26 are arranged at equal intervals along the circumference of the second bevel gear 24.

[0039] The stirring plates 26 are evenly distributed around the second bevel gear 24, with half above the mixture and half below it. When several stirring plates 26 rotate, they carry the crushed solid fertilizer floating on the surface of the mixture to the bottom of the mixture, further ensuring the thorough mixing of water and fertilizer.

[0040] In a further optimized design, a support block 27 is fixedly connected to the top of the inner wall of the tank body 1. The driving component includes a second connecting rod 28 rotatably connected to the support block 27. A fourth bevel gear 29 is fixedly connected to one end of the second connecting rod 28. The fourth bevel gear 29 meshes with the first bevel gear 15. A second motor 30 is fixedly connected to the outer wall of the tank body 1. The other end of the second connecting rod 28 extends out of the tank body 1 and is fixedly connected to the output shaft of the second motor 30.

[0041] The second connecting rod 28 is rotatably connected to the support block 27 via a bearing. The support block 27 ensures the stability of the second connecting rod 28 when it rotates. When the second motor 30 starts, it drives the second connecting rod 28 to rotate. The second connecting rod 28 drives the fourth bevel gear 29 to rotate. The fourth bevel gear 29 drives the first bevel gear 15 to rotate, thereby realizing the stirring of water and fertilizer in the tank 1.

[0042] In a further optimized design, several stirring rods 31 are fixedly connected to the outer wall of the stirring shaft 20, and the stirring rods 31 are located below the third bevel gear 25.

[0043] When the stirring shaft 20 rotates, it drives several stirring rods 31 to rotate, further ensuring the mixing effect.

[0044] In a further optimized design, a scraper 32 is fixedly connected to the end of the stirring rod 31 away from the stirring shaft 20, and the side of the scraper 32 away from the stirring shaft 20 is correspondingly set to the inner wall of the tank 1.

[0045] The scraper 32 follows the stirring shaft 20 to make a circular motion around the central axis of the tank 1, and follows the stirring rod 31 to make a circular motion around the stirring shaft 20. The scraper 32 slides in contact with the inner wall of the tank 1, thereby cleaning the residual fertilizer on the inner wall of the tank 1.

[0046] The design was further optimized by providing a discharge port 33 at the bottom of the tank body 1, and a valve 34 was installed on the discharge port 33.

[0047] The discharge port 33 is used to discharge the mixed water and fertilizer, and the valve 34 is used for control. Specifically, the water storage tank 2, the liquid fertilizer storage tank 3, and the solid fertilizer storage tank 4 are all provided with a feed port 35 at the top center.

[0048] This invention provides an integrated water and fertilizer automatic fertilizer application device. During use, solid fertilizer is pulverized by a pulverizing roller 9, and the pulverized fertilizer is stored in a solid fertilizer storage box 4. Simultaneously, during the pulverizing process, the pulverizing roller 9 drives a cleaning roller 10 to rotate via a first sprocket 12, a second sprocket 13, and a chain 36, cleaning any fertilizer adhering to the pulverizing roller 9. For mixing solid fertilizer and water, the pulverized fertilizer and water are simultaneously transported to a tank 1 through a first conveying pipe 5 and a second conveying pipe 6. A second motor 30 drives a fourth bevel gear 29 to rotate, which in turn drives a first bevel gear 15. The rotation of the first bevel gear 15, in turn, drives a second bevel gear... When the second gear 17 rotates, it drives the third gear 19 to rotate on its own axis and to move in a circular motion around the annular toothed plate 18. The circular motion of the third gear 19 drives the stirring shaft 20 to move in a circular motion inside the tank 1. The rotation of the third gear 19 drives the stirring shaft 20 and the stirring rod 31 to rotate, thereby realizing the mixing and stirring of water and fertilizer. At the same time, the first support plate 21 and the second support plate 22 follow the stirring shaft 20 to move in a circular motion around the second conveying pipe 6. The second bevel gear 24 rolls on the meshing third bevel gear 25. When it rolls, it drives several stirring plates 26 to rotate with the third bevel gear 25. When rotating, it further ensures that the powdery fertilizer floating on the water surface is mixed with the water.
