Description

Technical Field

[0001] This invention relates to the field of integrated water and fertilizer machine control technology, specifically to an integrated water and fertilizer machine control device based on a crop growth model. Background Technology

[0002] In order to prioritize food safety and the protection of the ecological environment, the development of green agriculture and green food is particularly important. Green agriculture, by ensuring that agricultural products are green and pollution-free, can not only improve people's health but also improve the ecological environment. In green agricultural production, the traditional water and fertilizer integrated machine irrigation method consumes a lot of water and wastes a lot of water. With the continuous development of technologies such as the Internet of Things, big data, and artificial intelligence, fully automatic water and fertilizer integrated machines will become more intelligent and networked. At present, the market combines crop growth models and alternating irrigation technology with water and fertilizer integrated machine control equipment, which can avoid the blindness and waste in the traditional water and fertilizer integrated machine irrigation and fertilization methods, reduce water and fertilizer waste, reduce agricultural pollution, and conform to the development concept of green agriculture. For example, the patent disclosed in the prior art with publication number "CN218851324U" is entitled "An Integrated Water and Fertilizer Management System". It discloses that the upper part of the box body is equipped with a water tank and a fertilizer solution tank. Both the water tank and the fertilizer solution tank have outlets and valves at their bottoms. An L-shaped partition is located on one side of the bottom of the box body, with a connecting hole in the vertical part of the partition. A through hole is opened on one side of the bottom of the box body, and a turntable is rotatably installed. The turntable has a water outlet. A stirring device is located on the other side of the bottom of the box body. Water is added to the water tank, and fertilizer solution is added to the fertilizer solution tank. By opening the two valves, the water and fertilizer solution can flow into the bottom of the box body. The stirring device can stir the water and fertilizer solution. The stirred fertilizer solution can then flow through the connecting hole and finally out through the water outlet. For example, in the prior art, the patent application with publication number "CN114731821A" entitled "A Complete Intelligent Water and Fertilizer Management System for a Base" discloses a fertilizer control unit including a storage box. A storage hopper is fixedly connected to the top of the inner wall of the storage box, and a solenoid valve is fixedly connected to the bottom of the storage hopper. A first motor is fixedly connected to the bottom of the back of the storage box, and one end of the output shaft of the first motor is fixedly connected to a rotating rod through a coupling. One end of the rotating rod passes through the storage box and extends into the interior of the storage box. The side of the rotating rod extending into the interior of the storage box is rotatably connected to the front of the inner wall of the storage box through a bearing. A rotating plate is fixedly connected to the surface of the rotating rod inside the storage box, and a weighing sensor is fixedly connected to the top of the rotating plate.

[0003] In the existing water and fertilizer integrated machine control equipment, although a stirring mechanism is installed inside the storage hopper, the fertilizer in the storage hopper accumulates near the solenoid valve after stirring. Over time, this causes the fertilizer near the solenoid valve to clump, which affects the subsequent fertilizer dispensing operation. Therefore, it affects the accuracy of fertilizer dispensing control and cannot effectively control the amount of water and fertilizer dispensed based on the crop growth model. This results in excessive or insufficient water and fertilizer, which affects crop growth. Therefore, we propose a water and fertilizer integrated machine control equipment based on a crop growth model to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a water and fertilizer integrated machine control device based on a crop growth model, in order to solve the problem mentioned in the background art. In the current water and fertilizer integrated machine control devices on the market, although a stirring mechanism is set inside the storage hopper, the fertilizer in the storage hopper accumulates near the solenoid valve after stirring. Over time, the fertilizer near the solenoid valve will clump together, which will affect the subsequent fertilizer dispensing operation. Therefore, it will affect the accuracy of the subsequent fertilizer dispensing control, and thus cannot effectively control the water and fertilizer dispensing amount of the water and fertilizer integrated machine based on the crop growth model, resulting in the problem of too much or too little water and fertilizer affecting crop growth.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water and fertilizer integrated machine control device based on a crop growth model, comprising an outer shell and a base frame installed on its bottom surface, wherein a controller is installed on the right side of the outer shell, a fertilizer storage chamber and a water storage chamber are installed through the upper surface of the outer shell, and a mixing chamber is fixed through the lower surface of the outer shell, wherein the bottom surfaces of the fertilizer storage chamber and the water storage chamber are connected to the upper surface of the mixing chamber through a material discharge control pipe, a material discharge control pipe is installed on the bottom surface of the mixing chamber, and a water pump is connected below the material discharge control pipe, wherein a spray pipe and a drip irrigation pipe for alternating irrigation are installed sequentially from top to bottom at the output end of the water pump, a second stirring rod is installed through the inside of the fertilizer storage chamber, and a material blocking mechanism is connected below the second stirring rod.

[0006] Preferably, a camera is connected to the front left side of the base frame, and a support frame is slidably engaged with the front right side of the base frame, with a soil moisture sensor installed at the front end of the support frame.

[0007] Preferably, a wind cup anemometer and a temperature and humidity sensor are installed sequentially from top to bottom on the upper left side of the outer casing.

[0008] Preferably, both the feeding control pipe and the discharge control pipe are equipped with solenoid valves and flow meters, and both the drip irrigation pipe and the spraying pipe are equipped with solenoid valves.

[0009] Preferably, a first stirring rod is installed through the interior of the mixing chamber, and the upper part of the first stirring rod penetrates the upper surface of the outer shell. Both the upper outer sides of the first stirring rod and the upper outer sides of the second stirring rod are equipped with mutually meshing transmission gears. Furthermore, arc-shaped control blocks are evenly spaced on the upper outer side of the first stirring rod, and the control blocks are fixedly installed on the transmission gears located on the upper outer side of the first stirring rod.

[0010] Preferably, the interior of the second stirring rod is hollow, and a vertical rod is slidably connected through the interior of the second stirring rod. The height of the vertical rod is higher than the height of the second stirring rod. Protrusions are symmetrically installed on the outer side of the vertical rod, and the protrusions are engaged and slidably connected with grooves opened in the inner sidewall of the second stirring rod. A connecting spring is installed in the groove opened in the inner sidewall of the second stirring rod, and the upper end of the connecting spring is connected to the protrusion. The material blocking mechanism includes arc-shaped receiving plates that are equally spaced on the bottom surface of the vertical rod, and the receiving plates have flow diversion grooves inside.

[0011] Preferably, a connecting ring plate is fixed to the upper outer side of the vertical rod, and a limiting frame is slidably connected to the outer side of the connecting ring plate. A protruding rod is installed on one side of the ring-shaped limiting frame, and a horizontal plate is fixed to the other side of the limiting frame. A guide rod is provided through the inside of the horizontal plate, and the bottom end of the guide rod is connected to the upper surface of the fertilizer storage chamber.

[0012] Preferably, the protruding rod forms a lifting structure through an adjusting block.

[0013] Preferably, an "L"-shaped connecting frame is installed at equal intervals on the outer side of the first stirring rod located in the mixing chamber, and a first magnet block is installed at the end of the connecting frame away from the first stirring rod.

[0014] Preferably, rotating rods are rotatably connected at equal intervals inside the upper cavity of the mixing chamber, and an arc-shaped feeding plate is fixed through the outer side of the rotating rods. A spiral spring is nested at the outer end of the rotating rods, and a second magnet with the same magnetic pole as the first magnet is installed on the bottom surface of the feeding plate. The feeding plate is positioned above the feeding control tube and below it.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the integrated water and fertilizer machine control device based on crop growth model facilitates further improvement in the accuracy of fertilizer dispensing control, thereby enabling the integrated water and fertilizer machine control device to effectively control the water and fertilizer dispensing amount based on the crop growth model. The specific details are as follows: (1) The first stirring rod can drive the second stirring rod to rotate through the transmission gear. The second stirring rod drives the vertical rod to rotate, so that the receiving plate can stir the fertilizer in the lower part of the fertilizer storage chamber. At the same time, the transmission gear on the outer side of the first stirring rod drives the upper arc-shaped control block to rotate, so that the control block drives the corresponding protrusion to rise. The protrusion drives the limit frame and the vertical rod to rise together. Therefore, the vertical rod and the receiving plate rotate and move up and down repeatedly, so that the arc-shaped receiving plate can receive part of the fertilizer first, avoiding the fertilizer from accumulating in the lower part of the fertilizer storage chamber and forming clumps. Therefore, it will not affect the later fertilizer feeding operation, and it is convenient to further improve the accuracy of fertilizer feeding control. Thus, it is convenient for the water and fertilizer integrated machine control equipment to control the water and fertilizer feeding of the water and fertilizer integrated machine based on the crop growth model. (2) The combined use of temperature and humidity sensors and wind cup anemometers can detect whether it is raining in the field. The soil moisture sensor monitors the soil moisture in real time, and the camera monitors the actual growth of crops in real time. The data is then transmitted to the controller. The controller analyzes the optimal water and fertilizer ratio and supply time based on the preset crop growth model, current soil data, current weather conditions and actual crop growth. Finally, by controlling the solenoid valves on the feed control pipe and discharge control pipe, water and fertilizer are mixed in proportion and delivered evenly and accurately to the crop roots. Therefore, the water and fertilizer ratio and supply can be automatically adjusted according to the crop growth needs to achieve the purpose of precise irrigation and fertilization. This not only improves the water and fertilizer utilization rate and reduces resource waste, but also significantly improves the growth efficiency and quality of crops, reduces agricultural pollution, conforms to the development concept of green agriculture, and avoids the blindness and waste in traditional irrigation and fertilization methods.

[0016] (3) By using drip irrigation pipes and sprinkler pipes alternately for irrigation, water can be supplied precisely according to the growth needs of crops, creating a good growth environment for crops. During the critical period when crops need water, the humidity and temperature in the field can be regulated by the sprinkler pipes to promote crop growth. At other times, the roots can be guaranteed to have sufficient water supply by the drip irrigation pipes, thereby effectively improving crop yield and quality, achieving the purpose of saving water and increasing efficiency, further improving the efficiency of water resource utilization, and avoiding over-irrigation and water waste.

[0017] (4) When the first stirring rod drives the connecting frame and the first magnet block to rotate, when the first magnet block rotates to the position below the second magnet block, the repulsive force between the first magnet block and the second magnet, which have the same magnetic poles, causes the material feeding plate to swing back and forth at a certain angle around the rotating rod. Therefore, the material feeding plate can spray fertilizer and water towards the direction of the first stirring rod, thereby making the fertilizer and water come into contact and mix quickly, which can improve the efficiency and effect of mixing fertilizer and water.

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.

[0021] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: The water and fertilizer integrated machine control device based on a crop growth model in this example further improves the accuracy of fertilizer dispensing control during use. This allows the device to effectively manage the water and fertilizer dispensing based on the crop growth model, automatically adjusting the water-fertilizer ratio and supply according to crop growth needs. This significantly improves crop growth efficiency and quality, avoiding the blind and wasteful practices of traditional irrigation and fertilization methods. For specific structure details, please refer to the attached diagram. Figures 1-8As shown, the system includes an outer casing 1 and a base frame 2 mounted on its bottom surface. A controller 3 is installed on the right side of the outer casing 1.

The bottom surfaces of the fertilizer storage chamber 4 and the water storage chamber 5 are connected to the upper surface of the mixing chamber 13 via a discharge control pipe 12. A discharge control pipe 131 is installed on the bottom surface of the mixing chamber 13, and the lower part of the discharge control pipe 131 is connected to a water pump 21. A spray pipe 10 and a drip irrigation pipe 9 for alternating irrigation are installed sequentially from top to bottom at the output end of the water pump 21. A second stirring rod 15 is installed through the interior of the fertilizer storage chamber 4. A material blocking mechanism is connected below the second stirring rod 15. A camera 11 is connected to the front left side of the base frame 2, and a support frame 201 is slidably engaged with the front right side of the base frame 2. A soil moisture sensor 8 is installed at the front end of the support frame 201. An anemometer 6 and a temperature and humidity sensor 7 are installed sequentially from top to bottom on the upper left side of the outer casing 1. A solenoid valve 121 and a flow meter 122 are installed on both the feeding control pipe 12 and the discharge control pipe 131. A solenoid valve 121 is installed on both the drip irrigation pipe 9 and the spray pipe 10. A first stirring rod 14 is installed through the interior of the mixing chamber 13, and the upper part of the first stirring rod 14 penetrates the upper surface of the outer casing 1. Both the upper outer sides of the first stirring rod 14 and the second stirring rod 15 are equipped with mutually meshing transmission gears 18. Arc-shaped control blocks 141 are evenly spaced on the upper outer side of the first stirring rod 14. The control blocks 141 are fixedly mounted on the transmission gears 18 located on the upper outer side of the first stirring rod 14. The interior of the second stirring rod 15 is hollow. A vertical rod 16 is slidably connected through the interior of the second stirring rod 15, and the height of the vertical rod 16 is greater than the height of the second stirring rod 15. Protrusions 161 are symmetrically installed on the outer side of the vertical rod 16, and the protrusions 161 are engaged and slidably connected with grooves opened in the inner wall of the second stirring rod 15. Connecting springs are installed in the grooves opened in the inner wall of the second stirring rod 15. Spring 162, and the upper end of spring 162 is connected to protrusion 161. The material blocking mechanism includes arc-shaped receiving plates 20 that are equally spaced on the bottom surface of vertical rod 16. The receiving plate 20 has a diversion groove 2001 inside. A connecting ring plate 163 is fixed on the upper outer side of vertical rod 16. A limit frame 17 is slidably connected to the outer side of connecting ring plate 163. A protrusion 172 is installed on one side of the ring-shaped limit frame 17. A horizontal plate 171 is fixed on the other side of the limit frame 17. A guide rod 173 is provided through the interior of the horizontal plate 171. The bottom end of the guide rod 173 is connected to the upper surface of fertilizer storage chamber 4. The protrusion 172 forms a lifting structure through the adjusting block 141.

[0022] Move the entire integrated water and fertilizer machine control equipment to the operating area. Then, manually pull out the pin on the outer right side of the base frame 2, and move the support frame 201 downwards to drive the soil moisture sensor 8. Once the lower end of the soil moisture sensor 8 is inserted into the soil, fix the support frame 201 to the base frame 2 using the pin. The soil moisture sensor 8 then monitors the soil moisture in real time. (A nutrient sensor can also be installed on the outside of the support frame 201 to monitor soil nutrients in real time.) The camera 11 monitors the actual growth of crops in real time. The temperature and humidity sensor 7, in conjunction with the anemometer 6, can detect whether it has rained in the field, and then transmit this data. The fertilizer is fed to controller 3. Controller 3 analyzes the optimal water-fertilizer ratio and supply time based on the preset crop growth model, current soil data, current weather conditions, and the actual growth of the crop. Finally, controller 3 controls the opening of the solenoid valves 121 and flow meters 122 on the three sets of feeding control pipes 12. At this time, through the coordinated use of solenoid valves 121 and flow meters 122, the fertilizer in the fertilizer storage chamber 4 falls into the mixing chamber 13 in a certain proportion through the feeding control pipes 12, and the water in the water storage chamber 5 falls into the mixing chamber 13 in a certain proportion through the feeding control pipes 12. Since this part is existing technology, it will not be described in detail here.

[0023] Meanwhile, the upper end of the first stirring rod 14 is connected to an external motor via a coupling. The motor drives the first stirring rod 14 to rotate. The lower part of the first stirring rod 14 stirs and mixes the water and fertilizer in the mixing chamber 13. The upper outer side of the first stirring rod 14 drives the second stirring rod 15 to rotate via three sets of meshing transmission gears 18. The second stirring rod 15 drives the vertical rod 16 to rotate. At the same time, the transmission gear 18 on the upper outer side of the first stirring rod 14 drives the arc-shaped control block 141 to revolve around the center of the first stirring rod 14. When the control block 141 rotates to contact the protrusion 172, the control block 141 pushes the protrusion 172 to move upward. The protrusion 172 drives the limiting frame 17 to move upward. Due to the limitation... A connecting ring plate 163 is slidably connected within the frame 17, without affecting the rotation of the vertical rod 16. Therefore, the connecting ring plate 163 causes the vertical rod 16 to move upwards. The protrusion 161 on the outer side of the vertical rod 16 slides within the groove of the second stirring rod 15. The connecting spring 162 is pulled and stores force. When the control block 141 rotates to separate from the protrusion 172, the stored force of the connecting spring 162 causes the vertical rod 16 to move downwards and reset. This causes the vertical rod 16 to rotate and rise / fall simultaneously with the arc-shaped receiving plate 20, allowing the receiving plate 20 to initially receive a portion of the fertilizer, while another portion falls through the diversion channel 2001. This prevents fertilizer from accumulating inside the lower part of the fertilizer storage chamber 4 and forming clumps, thus not affecting subsequent fertilizer feeding operations and facilitating... To further improve the accuracy of fertilizer dispensing control, the integrated water and fertilizer machine control equipment can effectively manage the amount of water and fertilizer dispensed based on crop growth models. When the flow meter 122 detects that the fertilizer and water have fallen to a certain amount, the solenoid valve 121 is closed, allowing the water and fertilizer to be mixed in proportion. After the water and fertilizer in the mixing chamber 13 are evenly mixed, the solenoid valve 121 and the flow meter 122 on the discharge control pipe 131 are opened, and the water pump 21 below is started. The water pump 21 delivers the water and fertilizer mixture in the discharge control pipe 131 to the drip irrigation pipe 9 or the spray pipe 10. The solenoid valve 121 on the drip irrigation pipe 9 and the spray pipe 10 is opened, providing precise water supply according to the crop's growth needs and creating a good growing environment for the crop. During critical water-demanding periods for crops, the solenoid valve 121 on the spray pipe 10 is opened, allowing the spray pipe 10 to spray a water-fertilizer mixture to regulate field humidity and temperature, promoting crop growth. At other times, the solenoid valve 121 on the drip irrigation pipe 9 is opened to ensure sufficient water supply to the roots, effectively improving crop yield and quality, achieving water conservation and efficiency, further enhancing water resource utilization efficiency, and avoiding over-irrigation and water waste. Therefore, it can automatically adjust the water-fertilizer ratio and supply according to crop growth needs, achieving precise irrigation and fertilization. This not only improves water and fertilizer utilization and reduces resource waste but also significantly enhances crop growth efficiency and quality, reduces agricultural pollution, and aligns with the development concept of green agriculture.This makes the integrated water and fertilizer management system, based on crop growth models, well-suited for use in green agriculture.

[0024] Example 2: The water and fertilizer integrated machine control device based on the crop growth model in this example, based on Example 1, enables rapid contact and mixing of fertilizer and water, thereby improving the efficiency and effectiveness of fertilizer and water mixing. For specific structure, please refer to the attached diagram. Figures 8-9 As shown, an "L"-shaped connecting frame 143 is installed at equal intervals on the outer side of the first stirring rod 14 located in the mixing chamber 13, and a first magnet block 142 is installed at the end of the connecting frame 143 away from the first stirring rod 14. A rotating rod 191 is rotatably connected at equal intervals inside the upper cavity of the mixing chamber 13, and an arc-shaped feeding plate 19 is fixed through the outer side of the rotating rod 191. A spiral spring 192 is nested at the outer end of the rotating rod 191, and a second magnet block 193 with the same magnetic pole as the first magnet block 142 is installed on the bottom surface of the feeding plate 19. The upper part of the feeding plate 19 is correspondingly arranged below the feeding control tube 12.

[0025] When the water and fertilizer are dropped into the mixing chamber 13 by the discharge control pipe 12, they first fall onto the corresponding arc-shaped feeding plate 19. Then, when the first stirring rod 14 drives the connecting frame 143 and the first magnet block 142 to rotate, when the first magnet block 142 rotates to the position below the corresponding second magnet block 193, the repulsive force between the first magnet block 142 and the second magnet block 193, which have the same magnetic poles, causes the feeding plate 19 to swing back and forth at a certain angle around the rotating rod 191. This allows the feeding plate 19 to spray fertilizer and water towards the direction of the first stirring rod 14, thereby allowing the fertilizer and water to come into contact and mix quickly, which can improve the efficiency and effect of fertilizer and water mixing.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
