Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer addition equipment, and in particular to fertilizer addition equipment for integrated water and fertilizer systems in greenhouses. Background Technology

[0002] As an important part of modern agriculture, the production efficiency and crop quality of greenhouses are directly affected by water and fertilizer management. Traditional fertilizer addition methods often rely on manual operation, which is not only inefficient but also makes it difficult to achieve uniform fertilizer distribution. To solve this problem, it is particularly important to design a fertilizer addition device for greenhouse water and fertilizer integration.

[0003] In practical use, traditional fertilizer addition equipment often lacks efficient mixing and stirring mechanisms as well as uniform feeding mechanisms, resulting in uneven addition and insufficient mixing of fertilizer, additives, and water. This affects the solubility and utilization rate of the fertilizer. In addition, traditional equipment often has uneven feeding problems, resulting in uneven distribution of fertilizer in greenhouses, with some areas having excess fertilizer and others having insufficient fertilizer. This not only wastes fertilizer but also affects the normal growth of crops. Improvements are urgently needed to address the issues of fertilizer addition efficiency and uniform feeding.

[0004] Therefore, to address the aforementioned issues of inconvenience in improving fertilizer addition efficiency and uniformly controlling feed quantity, a fertilizer addition device for integrated water and fertilizer systems in greenhouses can be designed. The output of the start-up motor drives the drive wheel to rotate via the drive shaft. The drive wheel is connected to the driven wheels on both sides via a transmission belt, thereby driving the feeding augers on both sides to rotate synchronously. The spiral blades of the feeding augers rotate continuously inside the inclined guide bin, pushing the fertilizer and auxiliary materials along the length of the guide bin to the other side, and finally dropping them into the mixing bin through the inlet. Simultaneously, an appropriate amount of water is added to the storage bin through the water inlet. In preparation for the subsequent mixing process, a mixing assembly and auxiliary assemblies are installed inside the mixing hopper. These components work together to thoroughly mix and stir the fertilizer, additives, and water, ensuring the uniformity and solubility of the fertilizer. In addition, multiple sets of stirring rods are installed on the side wall of the drive shaft. These stirring rods rotate under the drive shaft to further prevent fertilizer from settling at the bottom of the mixing hopper. Furthermore, by setting the drive motor to rotate slowly, the conveying speed of the feeding auger can be precisely controlled, thereby achieving a continuous and uniform feeding effect of fertilizer and additives. This not only improves the fertilizer addition efficiency but also ensures the uniform distribution of the fertilizer. Utility Model Content

[0005] To address the shortcomings of traditional fertilizer addition equipment, which often lacks efficient mixing and uniform feeding mechanisms, resulting in uneven addition and insufficient mixing of fertilizer, additives, and water, thus affecting fertilizer solubility and utilization, and further exacerbating the problem of uneven feeding, traditional equipment also suffers from uneven fertilizer distribution within greenhouses, leading to fertilizer over-distribution in some areas and under-distribution in others. This not only wastes fertilizer but also hinders normal crop growth. Therefore, improvements are urgently needed to enhance fertilizer addition efficiency and ensure uniform feeding.

[0007] Preferably, during the use of the fertilizer addition equipment, fertilizer and auxiliary materials are first fed into the corresponding storage bins through the feeding ports on both sides. The fertilizer, under the influence of gravity, slides down the inclined surface to the feeding port within the storage bin, and then enters the inclined guide bin. At this point, the drive motor is activated, and its output drives the drive wheel to rotate via the drive shaft. The drive wheel is connected to the driven wheels on both sides via a transmission belt, thereby driving the feeding augers on both sides to rotate synchronously. The spiral blades of the feeding augers rotate continuously inside the inclined guide bin, pushing the fertilizer and auxiliary materials along the length of the guide bin to the other side, and finally dropping them into the mixing bin through the feed inlet. Simultaneously, an appropriate amount of water is added to the storage bin through the water inlet for subsequent mixing. In the preparation process, a mixing assembly and auxiliary assemblies are installed inside the mixing hopper. These components work together to thoroughly mix and stir the fertilizer, additives, and water, ensuring the uniformity and solubility of the fertilizer. In addition, multiple sets of stirring rods are installed on the side wall of the drive shaft. These stirring rods rotate under the drive shaft to further prevent fertilizer from settling at the bottom of the mixing hopper. Furthermore, by setting the drive motor to rotate slowly, the conveying speed of the feeding auger can be precisely controlled, thereby achieving a continuous and uniform feeding effect of fertilizer and additives. This not only improves the fertilizer addition efficiency but also ensures the uniform distribution of fertilizer. In addition, activating the translation assembly can drive the entire water and fertilizer integration device to move smoothly and precisely in parallel, and the irrigation assembly can achieve a wide-range and uniform irrigation effect.

[0013] Preferably, the auxiliary components include a filter plate; the filter plate is installed inside the mixing chamber and is positioned above the stirring rod.

[0014] The beneficial effects of this utility model are:

[0015] During the operation of the fertilizer addition equipment, fertilizer and auxiliary materials are first fed into their respective storage silos through the feeding ports on both sides. The fertilizer, under the influence of gravity, slides down the inclined surface to the feed inlet within the storage silo, and then enters the inclined guide silo. At this point, the drive motor is activated, and its output drives the drive wheel to rotate via the drive shaft. The drive wheel is connected to the driven wheels on both sides via a transmission belt, which in turn drives the feeding augers on both sides to rotate synchronously. The spiral blades of the feeding augers rotate continuously inside the inclined guide silo, pushing the fertilizer and auxiliary materials along the length of the guide silo to the other side, and finally dropping them into the mixing silo through the feed inlet. Simultaneously, an appropriate amount of water is added to the storage silo through the water inlet for the subsequent mixing process. In preparation, the mixing hopper contains mixing and auxiliary components that work together to thoroughly mix fertilizer, additives, and water, ensuring the fertilizer's uniformity and solubility. Additionally, multiple stirring rods are mounted on the side wall of the drive shaft, rotating under its drive to further prevent fertilizer sedimentation at the bottom of the mixing hopper. Furthermore, the slow rotation of the drive motor precisely controls the conveying speed of the feeding auger, achieving continuous and uniform feeding of fertilizer and additives.

[0023] Please see Figures 1-5This utility model provides an embodiment of a fertilizer addition device for an integrated water and fertilizer system in a greenhouse, comprising a mixing silo 1, a feeding port 2, an inclined surface 3, a feed inlet 4, an inclined guide silo 5, a feeding auger 6, a loading port 7, a storage silo 8, a driven wheel 9, a driving wheel 10, a transmission belt 11, a driving motor 12, a stirring rod 13, a water inlet 14, a drive shaft 15, a translation component, a mixing component, an irrigation component, and auxiliary components; a translation component is provided above the mixing silo 1, a mixing component is provided inside the mixing silo 1, an auxiliary component is provided inside the mixing silo 1, an irrigation component is provided at the bottom of the mixing silo 1, two sets of inclined guide silos 5 are provided on both sides above the mixing silo 1, and a storage silo 8 is provided on one side above the inclined guide silo 5; the storage silo 8 is located above... The mixing chamber 8 is equipped with a feeding port 2. The inner wall of the storage silo 8 is provided with an inclined surface 3. The inner wall of the inclined surface 3 is provided with a feeding port 7. The bottom wall of the inclined guide silo 5 is provided with a feeding port 4. The inside of the inclined guide silo 5 is provided with a feeding auger 6. One end of the feeding auger 6 is provided with a driven wheel 9. The side of the storage silo 8 is provided with a drive motor 12. The output end of the drive motor 12 is provided with a drive shaft 15. One end of the drive shaft 15 is provided with a drive wheel 10. The outside of the drive wheel 10 is provided with a transmission belt 11. The drive wheel 10 is rotatably connected to the transmission belt 11. The driven wheel 9 is located inside the transmission belt 11 and is rotatably connected to the transmission belt 11. Multiple sets of stirring rods 13 are provided on the side wall of the drive shaft 15. A water inlet 14 is provided above the mixing chamber 1.

[0024] Please see Figure 2The translation assembly includes a translation slide rail 101, a translation motor 102, and a translation screw 103. The translation slide rail 101 is positioned above the storage hopper 8. A translation motor 102 is installed at one end of the translation slide rail 101, and a translation screw 103 is installed at the output end of the translation motor 102. The translation screw 103 is located inside the translation slide rail 101. Starting the translation motor 102 will drive the translation screw 103 to rotate. The translation assembly also includes a translation slider 104 and a translation bracket 105. A translation slider 104 is installed on the side wall of the translation screw 103, and the translation slider 104 is threadedly connected to the translation screw 103. Two sets of translation brackets 105 are installed on both sides of the translation slider 104, and one side of each translation bracket 105 is fixedly connected to the inner wall of the storage hopper 8. The translation screw 103 can be rotated by translation. The slider 104 drives the translation brackets 105 on both sides to move in parallel, so that the entire water and fertilizer integration device can move smoothly and precisely in parallel along the translation slide rail 101; the mixing component includes a mixing motor 201, a mixing shaft 202 and mixing rods 203; the mixing motor 201 is set above the mixing chamber 1, the output end of the mixing motor 201 is set with the mixing shaft 202, and multiple sets of mixing rods 203 are set on the side wall of the mixing shaft 202; starting the mixing motor 201 will drive the mixing shaft 202 to start rotating, which in turn drives the multiple sets of mixing rods 203 on the side wall to rotate together. These rotating mixing rods 203 generate a strong stirring effect inside the mixing chamber 1, which can fully mix fertilizer, auxiliary materials and water, ensure that various components are evenly distributed, and thus achieve an ideal mixing effect.

[0025] Please see Figures 3-5The irrigation assembly includes a liquid pump 301, two side diversion pipes 302, and connecting pipes 303. The liquid pump 301 is installed on the bottom wall of the mixing silo 1, and two side diversion pipes 302 are installed on the bottom wall of the liquid pump 301. Two sets of connecting pipes 303 are installed at both ends of each side diversion pipe 302. When the liquid pump 301 is started, it draws fertilizer from the mixing silo 1 and transports it into the two side diversion pipes 302. The irrigation assembly also includes a pressure valve 304, a spray pipe 305, and spray heads 306. A pressure valve 304 is installed on the side wall of the connecting pipe 303, and a spray pipe 305 is installed at the other end of the connecting pipe 303. Multiple sets of spray heads 306 are installed on the bottom wall of the spray pipe 305. Subsequently... By activating the pressurization valve 304, the fertilizer, under pressure, smoothly enters the spray pipe 305 through the connecting pipe 303. Finally, the fertilizer is sprayed out in the form of a fine mist and uniform water flow through multiple sets of spray heads 306, achieving a wide-range and uniform irrigation effect. The auxiliary components include a filter plate 401. The filter plate 401 is installed inside the mixing chamber 1 and is located above the stirring rod 13. The design of the filter plate 401 can slow down the sinking speed of the fertilizer, so that the fertilizer will not directly and quickly settle to the bottom of the mixing chamber 1, but has more time and opportunity to fully contact and mix with the stirring rod 13, achieving a more thorough and uniform mixing, thereby improving the mixing quality and effect of the fertilizer.

[0026] When the fertilizer adding equipment is in use, the fertilizer and auxiliary materials are first put into the corresponding storage bins 8 through the feeding ports 2 on both sides. The fertilizer is subjected to gravity in the storage bins 8 and slides down the inclined surface 3 to the feeding port 7, and then enters the interior of the inclined guide bin 5.

[0027] At this time, the active motor 12 is started. The output end of the active motor 12 drives the active wheel 10 to rotate through the active shaft 15. The active wheel 10 is connected to the driven wheels 9 on both sides through the transmission belt 11, thereby driving the feeding augers 6 on both sides to rotate synchronously. The spiral blades of the feeding auger 6 rotate continuously inside the inclined guide bin 5, pushing the fertilizer and auxiliary materials along the length of the guide bin to the other side, and finally falling into the mixing bin 1 through the feed inlet 4. At the same time, an appropriate amount of water is added to the storage bin 8 through the water inlet 14 to prepare for the subsequent mixing process.

[0028] Inside the mixing silo 1, starting the mixing motor 201 drives the mixing shaft 202 to rotate, which in turn drives multiple sets of mixing rods 203 on the side wall to rotate together. These rotating mixing rods 203 generate a strong stirring effect inside the mixing silo 1. Furthermore, the design of the filter plate 401 slows down the sinking speed of the fertilizer, preventing it from directly and quickly settling to the bottom of the storage silo 8. Instead, the fertilizer has more time and opportunity to fully contact and mix with the mixing rods 13, ensuring that the fertilizer, auxiliary materials, and water are thoroughly mixed, and that all components are evenly distributed, thus achieving an ideal mixing effect. Together, they thoroughly mix and stir the fertilizer, auxiliary materials, and water, ensuring the uniformity and solubility of the fertilizer.

[0029] In addition, multiple sets of stirring rods 13 are provided on the side wall of the drive shaft 15. These stirring rods 13 rotate under the drive of the drive shaft 15 to further prevent the fertilizer at the bottom of the mixing bin 1 from settling. In addition, by setting the drive motor 12 to rotate slowly, the conveying speed of the feeding auger 6 can be precisely controlled, thereby achieving a continuous and uniform feeding effect of fertilizer and auxiliary materials. This not only improves the fertilizer addition efficiency, but also ensures the uniform distribution of fertilizer.

[0030] After the mixing is completed, starting the translation motor 102 will drive the translation screw 103 to rotate. The translation screw 103 can then drive the translation supports 105 on both sides to move in parallel through the translation slider 104. This allows the entire water and fertilizer integration device to move smoothly and accurately along the translation slide rail 101. In this way, the device can accurately deliver the mixed fertilizer to the designated irrigation area according to the actual needs of the crops in the greenhouse.

[0031] Finally, the liquid pump 301 is started to extract the fertilizer in the mixing bin 1 and transport it to the two side diversion pipes 302. Then, by starting the pressure valve 304, the fertilizer is smoothly introduced into the spray pipe 305 through the connecting pipe 303 under pressure. Finally, the fertilizer is sprayed onto the roots or leaves of the crop in the form of a fine mist and uniform water flow through multiple sets of spray heads 306, achieving a wide range and uniform irrigation effect.

[0032] Throughout the process, all components work together to ensure the precise addition, uniform mixing, and effective irrigation of fertilizer, providing sufficient nutritional support for crop growth.

[0033] Through the above steps, during the use of the fertilizer addition equipment, fertilizer and auxiliary materials are first fed into the corresponding storage bins 8 through the feeding ports 2 on both sides. The fertilizer, under the influence of gravity, slides down the inclined surface 3 to the feeding port 7 within the storage bin 8, and then enters the inclined guide bin 5. At this time, the drive motor 12 is started. The output of the drive motor 12 drives the drive wheel 10 to rotate through the drive shaft 15. The drive wheel 10 is connected to the driven wheels 9 on both sides via the transmission belt 11, thereby driving the feeding augers 6 on both sides to rotate synchronously. The spiral blades of the feeding augers 6 rotate continuously inside the inclined guide bin 5, pushing the fertilizer and auxiliary materials along the length of the guide bin to the other side, and finally falling into the mixing bin 1 through the feeding port 4. Simultaneously, an appropriate amount of water is added to the storage bin 8 through the water inlet 14. To prepare for the subsequent mixing process, a mixing assembly and an auxiliary assembly are installed inside the mixing hopper 1. These components work together to thoroughly mix and stir the fertilizer, additives, and water, ensuring the uniformity and solubility of the fertilizer. In addition, multiple sets of stirring rods 13 are installed on the side wall of the drive shaft 15. These stirring rods 13 rotate under the drive of the drive shaft 15, further preventing the fertilizer from settling at the bottom of the mixing hopper 1. Furthermore, by setting the drive motor 12 to rotate slowly, the conveying speed of the feeding auger 6 can be precisely controlled, thereby achieving a continuous and uniform feeding effect of fertilizer and additives. This not only improves the fertilizer addition efficiency but also ensures the uniform distribution of fertilizer. In addition, activating the translation assembly can drive the entire water and fertilizer integration device to move smoothly and precisely in parallel, and the irrigation assembly can achieve a wide-range and uniform irrigation effect.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
