Description

Technical Field

[0001] This invention relates to the field of agricultural production technology, specifically to an intelligent water and fertilizer machine for water-saving irrigation. Background Technology

[0002] Intelligent water and fertilizer machines are core equipment for water-saving irrigation and precision fertilization. By integrating irrigation and fertilization with intelligent control, they achieve efficient utilization of water resources and fertilizers. They are important technological equipment for smart agriculture and precision agriculture. Their core objective is to solve the drawbacks of traditional irrigation, such as "flood irrigation," and fertilization, such as "experience-based" fertilization. By supplying on demand, they reduce resource waste, improve agricultural production efficiency and ecological benefits, collect farmland environment and crop growth data through data sensing, capture signals such as drought and insufficient fertility, generate personalized irrigation and fertilization plans through intelligent decision-making, implement decision-making instructions through precise execution, and automatically adjust irrigation volume and fertilizer concentration through dynamic adjustment to achieve on-demand supply. Current fertigation systems typically mix water and fertilizer to produce liquid fertilizer. However, during this process, insoluble fertilizer particles can increase the pressure on the water pump and drip irrigation system, and can easily cause blockages. Adding a filter can alleviate the blockage caused by fertilizer particles, but the intercepted material needs to be cleaned frequently, resulting in high maintenance costs. Furthermore, this portion of fertilizer can lead to insufficient application and reduced resource utilization. Summary of the Invention

The annular pipe is fixedly installed on the inner bottom of the water and fertilizer tank, and the edge of the annular pipe is connected to several sets of irrigation water pipes that penetrate the water and fertilizer tank. An electric control valve is installed on the irrigation water pipe. An inclined filter screen is detachably installed on the inner side of the interception box along the inclined direction.

[0011] As a preferred technical solution of the intelligent water and fertilizer machine for water-saving irrigation according to the present invention, the central pipes at the discharge ends of the water outlet pipe and the material outlet pipe are both connected to the dispersing cylinder, and a mixing cylinder is connected to one discharge end of the dispersing cylinder. A support is fixedly installed on the inner side of the dispersion cylinder, and a drive blade is rotatably connected to the middle of the support via a rotating shaft.

[0013] As a preferred technical solution of the intelligent water and fertilizer machine for water-saving irrigation according to the present invention, the discharge end of the mixing cylinder is connected to the inside of the distribution ring cavity through a connecting pipe, and the edge of the spiral conveying blade is in contact with the inner wall of the mixing cylinder.

[0014] Compared with the prior art, the present invention provides an intelligent water and fertilizer machine for water-saving irrigation, which has the following beneficial effects: 1. Pressurized water and gas from the outside can be conveniently delivered to the top and bottom casings respectively through the water inlet and air inlet pipes. This allows for the rotation of the drive toothed disc and grinding toothed disc via high pressure. The pressurized cone pipe enhances the drive response speed of the drive toothed disc and grinding toothed disc. The airflow is used to transport fertilizer, achieving initial dispersion. When the grinding toothed disc is driven to rotate by the airflow carrying fertilizer, the fertilizer is ground by the grinding toothed disc and grinding blocks, achieving initial grinding and refining of fertilizer particles. The drive toothed disc drives the inner conical grinding head to rotate in the grinding chamber. Combined with the grinding strips on the inner wall of the grinding chamber and the conical surface of the inner conical grinding head, the fertilizer mixed with water is further ground and refined, reducing the fertilizer particle size and inhibiting subsequent blockage from the source. This ensures continuous water delivery and irrigation without the need for manual maintenance. Furthermore, the water carrying fertilizer is first concentrated through a central pipe and then evenly distributed in a distribution ring cavity. Then, the water and fertilizer are evenly introduced into the grinding chamber from multiple points using inclined holes to ensure uniform dispersion of the water-fertilizer mixture. This refines the fertilizer while allowing it to mix more thoroughly with the water, thus improving the mixing effect.

[0015] 2. The mixing outlet and external square pipe facilitate the export and transportation of the ground and mixed water and fertilizer. The inclined filter screen in the interception box intercepts the fertilizer, ensuring that fertilizers with inconsistent particle sizes are not used for direct irrigation. At the same time, based on the return pipe, delivery pump and diffuser, the intercepted fertilizer can be centrally collected and diffused, thus forming a rework path so that the intercepted fertilizer can be reintroduced into the distribution ring cavity to participate in the subsequent secondary grinding and mixing process, so that the fertilizer is fully refined, ensuring the mixing rate and utilization rate of the fertilizer, and avoiding fertilizer waste. At the same time, the ring pipe facilitates the centralized collection and distribution of water and fertilizer, allowing multiple irrigation pipes to be used flexibly for irrigation, improving the adaptability of the water and fertilizer irrigation process.

[0016] 3. The centralized pipe facilitates the initial collection of water and fertilizer discharged from the outlet pipe and the discharge pipe. The combined pressure of water flow pressure and air flow pressure drives the rotating blades and dispersing blades, enabling the water and fertilizer to undergo effective premixing within the dispersing cylinder. Simultaneously, the rotating blades and dispersing blades impact and crush the fertilizer, ensuring effective premixing of fertilizer and water. Combined with the movable shaft and spiral conveying blades within the mixing cylinder, the water and fertilizer mixture can be further mixed using the homogenizing conveying effect of the spiral conveying blades before entering the distribution ring cavity, thereby improving the subsequent water and fertilizer mixing effect.

Grinding strips 12 are evenly distributed on the inner wall of the grinding chamber 10 and the outer conical surface of the inner conical grinding head 11. A bearing seat 13 is provided at the bottom of the inner conical grinding head 11. A fixed shaft 14 that cooperates with the bearing seat 13 is installed at the center of the bottom of the grinding chamber 10. The inner conical grinding head 11 rotates stably inside the grinding chamber 10 through the bearing seat 13 and the fixed shaft 14. A sealing bushing is provided at the bottom of the grinding chamber 10 at the edge of the bearing seat 13 to facilitate the stable rotation of the inner conical grinding head 11 inside the grinding chamber 10. The sealing bushing can also seal the rotating connection position at the bottom of the inner conical grinding head 11 to prevent the water-fertilizer mixture from entering. A top sleeve 15 is fixedly installed on the inner top of the water-fertilizer tank 1 via a stabilizing bracket. A drive gear 16 is rotatably connected to the inner side of the top sleeve 15. A bottom sleeve 17 is fixedly installed on the bottom of the outer grinding cylinder 9. The water inlet pipe 5 is connected to an external water supply pipe via a booster water pump. A booster blower is connected to the air inlet end of the air inlet pipe 6. The fertilizer hopper 7 is connected to a fertilizer conveying pipe. The discharge ends of the water inlet pipe 5 and the air inlet pipe 6 extend into the interior of the top sleeve 15 and the bottom sleeve 17, respectively. The discharge ends of the water inlet pipe 5 and the air inlet pipe 6 are directly opposite the middle of the drive gear 16 and the grinding gear 18, respectively. Pipe 6 facilitates the delivery of pressurized water and gas from the outside to the top sleeve 15 and bottom sleeve 17 respectively, thereby driving the drive gear 16 and grinding gear 18 to rotate within the top sleeve 15 and bottom sleeve 17. The grinding gear 18 is rotatably connected and embedded inside the bottom sleeve 17, and evenly distributed grinding teeth 19 are provided on the inner wall of the bottom sleeve 17. The drive gear 16 and grinding gear 18 rotate within the top sleeve 15 and bottom sleeve 17 respectively via the movable shaft 20, and the drive gear 16 drives the inner conical grinding head 11 to rotate within the grinding cavity 10 via the movable shaft 20 installed at its bottom. A mixing outlet 21 is provided on the bottom side of the grinding chamber 10, and an external square tube 22 connected to the mixing outlet 21 is connected to the side of the outer grinding cylinder 9. A water outlet pipe 23 is connected to the side outlet end of the top sleeve 15, and a material outlet pipe 24 is connected to the side outlet end of the bottom sleeve 17.

[0030] An interception box 28 is connected to the outlet end of the external square tube 22, and an annular tube 29 is connected to the discharge end of the bottom of the interception box 28 through the output square tube. The annular tube 29 is fixedly installed on the inner bottom of the water and fertilizer tank 1, and several sets of irrigation water pipes 30 penetrating the water and fertilizer tank 1 are connected to the side of the annular tube 29. An electric control valve 31 is installed on the irrigation water pipe 30. The irrigation water pipe 30 is internally connected to the annular tube 29. The control panel 3 converts the irrigation and fertilization scheme into decision commands to control the electric control valve 31 on the corresponding irrigation water pipe 30 to implement the response. The irrigation water pipe 30 is connected to the field drip irrigation pipeline, which facilitates the centralized collection and distribution of water and fertilizer, so that multiple irrigation water pipes 30 can be used for irrigation at the same time, and at the same time realizes on-demand supply to reduce water waste and achieve the purpose of water-saving irrigation. An inclined filter screen 32 is detachably installed on the inner side of the interception box 28 along the inclined direction.

This facilitates the centralized collection of the intercepted fertilizer and subsequent diffusion and transportation. A delivery pump 34 is installed on the return pipe 33, and the return pipe 33 extends into the distribution ring cavity 26 through the diffusion cover 35 at its end.

[0031] The central pipe 25 at the discharge end of the water outlet pipe 23 and the material outlet pipe 24 is connected to the dispersing cylinder 36, and a mixing cylinder 37 is connected to one side of the discharge end of the dispersing cylinder 36. A bracket 38 is fixedly installed on the inner side of the dispersing cylinder 36, and a drive blade 39 is rotatably connected to the middle of the bracket 38 via a rotating shaft.

The drive blade 39 and the dispersing blades 40 enable the water flow and fertilizer to be effectively premixed in the dispersing cylinder 36. A rotating shaft 41 is rotatably connected to the center of the inner side of the mixing cylinder 37 via a shaft bracket. A spiral conveying blade 42 is fixedly connected to the edge of the rotating shaft 41. The discharge end of the mixing cylinder 37 is connected to the inside of the distribution ring cavity 26 via a connecting pipe. The edge of the spiral conveying blade 42 is in contact with the inner wall of the mixing cylinder 37. The spiral conveying blade 42 is used to mix the water-fertilizer mixture, so that the mixed water-fertilizer mixture in the mixing cylinder 37 can be conveniently transported to the distribution ring cavity 26.

[0032] The working principle and usage process of this invention: In actual application, the water and fertilizer tank 1 is integrated with the external control box. The external data sensing device collects farmland environment and crop growth data, captures signals of drought and insufficient fertility, and the controller generates an irrigation and fertilization plan based on the signal feedback. The control panel 3 uses visualization and interactive functions to accurately implement the irrigation and fertilization plan, thereby achieving on-demand supply and reducing water waste, achieving the purpose of water-saving irrigation, and improving agricultural production efficiency and ecological benefits by dynamically adjusting the irrigation volume and fertilizer concentration. The control panel 3 converts the irrigation and fertilization plan into decision commands to control the electric control valve 31 on the corresponding irrigation water pipe 30 to implement the response. The irrigation water pipe 30 is connected to the field drip irrigation pipeline, and the ring pipe 29 collects and distributes water and fertilizer in a centralized manner, so that multiple irrigation water pipes 30 can be used for irrigation at the same time, achieving on-demand supply and reducing water waste. In the process of mixing and preparing water and fertilizer, the water inlet pipe 5 is first connected to the external water supply pipe through a booster water pump, the air inlet pipe 6 is connected to a booster blower, and the fertilizer hopper 7 is connected to the fertilizer conveying pipe. At the same time, the discharge ends of the water inlet pipe 5 and the air inlet pipe 6 are extended to the inside of the top sleeve 15 and the bottom sleeve 17 respectively, facing the middle of the drive toothed disc 16 and the grinding toothed disc 18. The pressurized water and gas from the outside are delivered to the top sleeve 15 and the bottom sleeve 17 respectively through the water inlet pipe 5 and the air inlet pipe 6. The high pressure drives the drive toothed disc 16 and the grinding toothed disc 18 to rotate. The booster cone pipe 8 increases the rotation response speed of the drive toothed disc 16 and the grinding toothed disc 18. The fertilizer is transported by airflow, so that the fertilizer is initially dispersed when it enters the air inlet pipe 6. When the airflow carrying the fertilizer drives the grinding toothed disc 18 to rotate, the fertilizer will be ground by the grinding toothed disc 18 and the grinding toothed block 19, so as to achieve the initial grinding and refining of the fertilizer particles. Next, the water discharged from the outlet pipe 23 and the discharge pipe 24 and the pre-ground fertilizer are initially concentrated through the central pipe 25. The driving blade 39 and the dispersing blade 40 in the dispersing cylinder 36 are driven to rotate based on the water flow pressure and air flow pressure. The driving blade 39 and the dispersing blade 40 are used to effectively premix the water flow and fertilizer in the dispersing cylinder 36. At the same time, the fertilizer is subjected to impact crushing and impact dispersion treatment to ensure that the fertilizer and water flow can be pre-mixed effectively. Combined with the spiral conveying blade 42 in the mixing cylinder 37, the water and fertilizer mixture can be mixed by the homogenizing conveying action of the spiral conveying blade 42 before entering the distribution ring cavity 26, thereby improving the subsequent water and fertilizer mixing effect. After the water-fertilizer mixture is dispersed and mixed in the dispersion cylinder 36 and the mixing cylinder 37, it enters the distribution ring cavity 26 from the discharge end of the mixing cylinder 37. The distribution ring cavity 26 distributes the mixture evenly, and the water-fertilizer mixture is evenly introduced into the grinding cavity 10 from multiple points using the evenly distributed inclined holes 27 to ensure the uniform dispersion of the water-fertilizer mixture. At this time, the rotation of the drive toothed disc 16 drives the inner conical grinding head 11 to rotate in the grinding cavity 10. The grinding strip 12 further grinds and refines the fertilizer in the mixed water flow, so that the fertilizer can be more fully mixed with the water. After the water and fertilizer are ground and mixed, the ground and mixed water and fertilizer are discharged and transported through the mixing outlet 21 at the bottom of the grinding chamber 10 and the external square pipe 22. The inclined filter screen 32 in the interception box 28 is used to intercept the fertilizer, ensuring that the fertilizer with the wrong particle size does not participate in the subsequent irrigation. The intercepted fertilizer is collected and transported in a centralized manner by the return pipe 33, the delivery pump 34 and the diffuser 35, so that the intercepted fertilizer can be reintroduced into the distribution ring cavity 26 to participate in the subsequent secondary grinding and mixing process, so that the fertilizer is completely refined. At the same time, the discharge end of the interception box 28 is connected to the ring pipe 29, through which the water and fertilizer are centrally distributed and transported to multiple irrigation water pipes 30. With the help of the electric control valve 31, the multiple irrigation water pipes 30 can be used flexibly for irrigation.
