Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural fertilization and irrigation, and in particular relates to an automated farmland fertilization device based on soil Beidou positioning. Background Art

[0002] With the development of agricultural modernization, the concept of precision agriculture has gradually emerged. Precision agriculture requires precise control of fertilizer application amount, timing, and location based on the actual conditions of farmland soil, such as soil fertility, pH, and moisture content. This approach improves fertilizer utilization, reduces resource waste and environmental pollution, and increases crop yield and quality.

[0003] A Chinese patent publication numbered CN 111527928 B discloses an automated farmland irrigation and fertilization device, which relates to the agricultural field. The device comprises an irrigation box and a planting box. The planting boxes are arranged in two groups, one at the front and one at the rear of the irrigation box. A device box is fixedly mounted on the top of the irrigation box. The device box is a rectangular box with a hollowed-out top. Spray boxes are fixedly mounted on the front and rear of the device box. In the present invention, when rainwater accumulates in the spray box to a certain level, the water pushes a float, which drives a prompt rod upward, thereby providing a prompt to the outside world. When the water level in the spray box reaches a certain level, the water is transferred from the spray box to a spray device in the spray equipment box via a control transmission device through a transmission pipe. The spray device and nozzle spray the crops, thereby achieving effective and precise control of the amount of water for irrigation.

[0004] Traditional fertilization methods often involve manual spreading or simple mechanical spreading, which has many drawbacks. On the one hand, manual spreading is inefficient and labor-intensive, and the amount of fertilizer applied is difficult to accurately control, which can easily lead to uneven fertilization. This can result in excessive fertilizer in some areas, causing fertilizer waste and environmental pollution, while insufficient fertilizer in other areas affects crop growth. On the other hand, although simple mechanical spreading has improved fertilization efficiency to a certain extent, it is also difficult to accurately apply fertilizer based on the actual nutritional status of the soil in different areas, and cannot meet the differentiated nutrient needs of crops. However, most fertilization equipment currently on the market lacks accurate soil monitoring and positioning functions, making it impossible to achieve precise fertilization based on the actual soil conditions. In addition, in the agricultural production process, uniform mixing and uniform fertilization of fertilizers are crucial to the growth of crops. If fertilizer and water are not mixed evenly, the concentration of the fertilizer solution will be inconsistent. During the fertilization process, some crops may suffer from fertilizer damage due to excessively high fertilizer concentrations, while others may not receive sufficient nutrients due to low fertilizer concentrations, thus affecting the overall growth and yield of the crops. Currently, although some fertilization equipment has a mixing function, the mixing effect is often unsatisfactory. These devices typically use a fixed stirring method and cannot be flexibly adjusted according to the characteristics of the fertilizer and water and the degree of mixing. This leads to insufficient mixing and the fertilizer solution is prone to stratification or agglomeration. Moreover, during the fertilization process, existing fertilization equipment cannot ensure that the fertilizer water is evenly sprayed to all areas of the farmland, resulting in poor fertilization uniformity and failure to meet the uniform nutrient requirements of crops. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated farmland fertilization device based on soil Beidou positioning, so as to solve the technical problems that the existing technology cannot be flexibly adjusted according to the characteristics of fertilizer and water and the degree of mixing, resulting in insufficient mixing and easy stratification or agglomeration of the fertilizer solution; and the existing fertilization equipment is difficult to ensure that the fertilizer water is evenly sprayed to various areas of the farmland, the fertilization uniformity is poor, and it cannot meet the uniform nutrient requirements of crops.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] A fertilizer barrel, wherein a bracket is installed at the bottom end of the fertilizer barrel, a plurality of water pipe networks are laid at the bottom of the fertilizer barrel, a plurality of fertilizer devices are arranged on the top of the water pipe networks, a side wall of the fertilizer barrel is connected to an arc-shaped plate, the top of the arc-shaped plate is connected to a support plate, a driver is installed at the center of the top of the support plate, and a mixing assembly is arranged inside the fertilizer barrel.

The top of the plug rod is provided with a water outlet pipe, the water outlet pipe is installed at the top of the water pipe network, and the water outlet pipe is connected to the inside of the water pipe network.

[0010] Preferably, a double-headed sprinkler is installed at the top end of the water outlet pipe, and hollow blades are provided on both sides of the double-headed sprinkler, and the two hollow blades are asymmetrically connected to the two water outlet ends of the double-headed sprinkler.

[0011] Preferably, a liquid flow controller is provided on one side of the water outlet pipe, and the liquid flow controller is connected to the inside of the water pipe network.

[0012] Preferably, a positioning patch is connected to the back of the liquid flow controller, and a sensor is provided on one side of the insertion rod, and the sensor is embedded in the soil.

[0013] Preferably, the fertilizing device further comprises a central controller, and the liquid flow controller and the driver are both controlled by the central controller.

[0014] Preferably, the mixing assembly includes a mixing rod, a baffle, a rotating belt, a stirring plate and a circular hole, and the top end of the mixing rod is rotatably connected to the center of the bottom end of the support plate.

[0015] Preferably, the driver is a bidirectional motor, and the output end of the driver passes through the center of the support plate and is transmission-connected to the top end of the mixing rod.

[0016] Preferably, the bottom end of the mixing rod is connected to a baffle, and the top of the mixing rod is connected to two rotating belts, which surround the middle part of the mixing rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention uses sensors to monitor soil nutrient content in real time, and combined with Beidou positioning technology, it can accurately identify the soil fertility status of different areas of farmland. This allows the device to accurately control the amount of fertilizer applied according to the actual situation of each area, avoiding the problem of uneven fertilization in traditional fertilization methods. For areas with low fertility, the amount of fertilizer applied can be appropriately increased to meet the growth needs of crops; for areas with high fertility, the amount of fertilizer applied can be reduced to prevent fertilizer waste and environmental pollution. Precision fertilization can ensure that crops receive just the right nutrient supply, promote healthy crop growth, thereby improving crop yield and quality, and increasing farmers' economic benefits. The device realizes full automation from soil monitoring to fertilization control. Manual labor only needs to perform the initial fertilizer and water application operations, and the subsequent fertilization process is automatically completed by the device. This greatly reduces the number of manual intervention links and reduces labor intensity, and is particularly suitable for fertilization operations in large-scale farmland. At the same time, automated fertilization improves fertilization efficiency, shortens fertilization time, and reduces labor and time costs. In addition, precision fertilization reduces fertilizer waste, reduces fertilizer procurement costs, and further improves the economic benefits of agricultural production.

[0020] (2) The present invention uses a driver to drive the stirring plate up and down so that the fertilizer and water can be fully mixed. This dynamic mixing method can be flexibly adjusted according to the characteristics of the fertilizer and water and the degree of mixing, avoiding the problem of insufficient mixing caused by the traditional fixed stirring method. The concentration of the fertilizer solution after full mixing is uniform, and there will be no stratification or agglomeration, ensuring that every drop of fertilizer water contains balanced nutrients. During the fertilization process, the uniform fertilizer solution can provide a stable nutrient supply for crops, which is conducive to the balanced growth of all parts of the crops and improves the overall quality and stress resistance of the crops. Combined with precise fertilization control technology, the device can ensure that the fertilizer water is evenly sprayed to all areas of the farmland. Uniform fertilization avoids the differences in crop growth caused by uneven fertilization, making the crop growth conditions in the farmland more consistent. This is not only conducive to the unified management and harvesting of crops, but also improves the overall utilization rate of farmland. At the same time, uniform fertilization helps to improve the nutrient distribution of the soil, reduce the adverse effects of excessive or low local soil fertility on crop growth, promote the balance and stability of the soil ecosystem, and lay the foundation for the sustainable development of agriculture.

[0031] The fertilizing device includes a rod 31, a water outlet pipe 32, a double-headed sprinkler 33, hollow blades 34, and a liquid flow controller 35. The top of the rod 31 is provided with a water outlet pipe 32, which is installed at the top of the water pipe network 2 and communicates with the interior of the water pipe network 2. The top of the water outlet pipe 32 is provided with a double-headed sprinkler 33, and hollow blades 34 are provided on both sides of the double-headed sprinkler 33. The two hollow blades 34 are asymmetrically connected to the two water outlet ends of the double-headed sprinkler 33. A liquid flow controller 35 is provided on one side of the water outlet pipe 32, and the liquid flow controller 35 is communicated with the interior of the water pipe network 2.

A mixing component is set inside the fertilizer barrel 1 for mixing fertilizer and water.

[0034] The fertilizing device includes a rod 31, with a water outlet pipe 32 at the top of the rod 31. The water outlet pipe 32 is installed at the top of the water pipe network 2 and is connected to the inside of the water pipe network 2. A double-headed sprayer 33 is installed at the top of the water outlet pipe 32. Hollow fan blades 34 are asymmetrically connected on both sides of the double-headed sprayer 33 to expand the spraying range.

[0035] A liquid flow controller 35 is installed on one side of the water outlet pipe 32 and communicates with the internal water pipe network 2 to control the output of fertilizer water.

A sensor 37 is installed on one side of the rod 31 and is embedded in the soil to monitor soil nutrient content. The fertilization device also includes a central controller 38, which controls both the liquid flow controller 35 and the driver 6.

[0036] Working Principle: Multiple sets of sensors 37 for fertilization devices are pre-buried in different areas of farmland. During fertilization, sensors 37 monitor soil nutrient content and transmit this information to a central controller 38. After receiving this information, the central controller 38 combines it with Beidou positioning information from positioning patches 36 to analyze soil conditions in different areas. It then precisely controls liquid flow controllers 35 at corresponding locations to output fertilizer-containing liquid into outlet pipes 32. The double-headed sprayer 33 and hollow fan blades 34 evenly spray the fertilizer water to the corresponding areas, achieving Beidou-based automated farmland fertilization and enabling precise fertilization based on soil conditions in different areas.

[0037] refer to Figures 1-6 As shown, the mixing assembly includes a mixing rod 71, a baffle 72, a rotating belt 73, a stirring plate 74 and a circular hole 75. The top end of the mixing rod 71 is rotatably connected to the center of the bottom end of the support plate 5. The driver 6 is specifically a bidirectional motor. The output end of the driver 6 passes through the center of the support plate 5 and is transmission-connected to the top end of the mixing rod 71. The bottom end of the mixing rod 71 is connected to the baffle 72. The top of the mixing rod 71 is connected to two rotating belts 73. The rotating belts 73 surround the middle part of the mixing rod 71. The middle part of the mixing rod 71 is provided with a stirring plate 74. The center of the stirring plate 74 is provided with a circular hole 75. The inner wall of the circular hole 75 is slidably connected to the outer wall of the mixing rod 71. The bottom end of the rotating belt 73 is connected to the top of the stirring plate 74.

[0038] The mixing assembly includes a mixing rod 71, the top of which is rotatably connected to the center of the bottom end of the support plate 5. The output end of the driver 6 extends through the center of the support plate 5 and is in driving connection with the top of the mixing rod 71. The bottom end of the mixing rod 71 is connected to a baffle 72, and the top is connected to two rotating belts 73, which surround the middle of the mixing rod 71. A stirring plate 74 is located in the middle of the mixing rod 71. A circular hole 75 is defined in the center of the stirring plate 74. The inner wall of the circular hole 75 is in sliding connection with the outer wall of the mixing rod 71. The bottom end of the rotating belt 73 is connected to the top of the stirring plate 74.

[0039] Working Principle: After manually adding fertilizer and water to the fertilizer barrel 1, driver 6 is activated. Clockwise rotation of driver 6 drives mixing rod 71, while rotating belt 73 winds around mixing rod 71, causing stirring plate 74 to move upward. Counterclockwise rotation of driver 6 straightens rotating belt 73, moving it away from mixing rod 71 and causing stirring plate 74 to move downward. Stirring plate 74 moves up and down within the fertilizer barrel 1, thoroughly stirring the fertilizer and water for a uniform mixture.

[0040] During the fertilization process, the sensor 37 monitors the soil nutrient content in real time. The central controller 38 controls the liquid flow controller 35 to output the appropriate amount of fertilizer water based on the monitoring information and the positioning of the positioning patch 36. The water pipe network 2 transports the fertilizer water to each fertilization device 3. The double-headed sprayer 33 and the hollow fan blades 34 spray the fertilizer water evenly into the farmland to ensure uniform fertilization.
