Abstract
Description
Technical Field
[0001] This application relates to the field of crop irrigation technology, and in particular to an integrated water and fertilizer machine. Background Technology
[0002] Fertilizer blenders, as advanced agricultural machinery, are increasingly widely used in vegetable greenhouses and plant factories. By precisely controlling the proportions and mixing process of various fertilizers, fertilizer blenders can automatically, quickly, and accurately prepare fertilizers according to the growth needs of plants. They mainly consist of a raw material storage and conveying system, a batching system, a mixing system, and a control system. During operation, raw fertilizers undergo storage, conveying, batching, and mixing processes to ultimately form a fertilizer product that meets the required specifications.
[0003] With the continuous development of modern agricultural technology, the performance requirements for fertilizer blending machines are becoming increasingly stringent, especially in terms of the accuracy of EC (electrical conductivity) and pH (acidity / alkalinity) in water and fertilizer, as well as blending efficiency. Modern plant factories have very high requirements for the precision of EC and pH values of water and fertilizer required for crop growth. The EC value reflects the concentration of soluble salts in the solution and is crucial for plant growth. The pH value determines the acidity or alkalinity of the fertilizer and has a direct impact on the plant's growth environment. Therefore, fertilizer blending machines need to be able to accurately control the EC and pH values of fertilizers to meet the growth needs of plants. However, the fertilizer blending machines currently in use are still relatively low in terms of blending precision and efficiency. Due to the diversity of raw materials, differences in their flowability and viscosity, and possible errors during the blending process, it is difficult for fertilizer blending machines to achieve ideal blending precision. In addition, the production efficiency of fertilizer blending machines is also constrained by factors such as equipment design, process flow, and degree of automation. Utility Model Content
[0004] The purpose of this application is to provide an integrated water and fertilizer machine to solve the problems of low fertilizer mixing accuracy and low production efficiency in existing fertilizer mixing machines.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0006] This application provides an integrated water and fertilizer machine, comprising:
[0007] frame;
[0008] Fertilizer mixing tanks are installed on the frame;
[0009] The pump's inlet end is connected to the fertilizer mixing tank;
[0010] The main pipeline is connected to the outlet end of the pump.
[0011] The water inlet pipe is connected to the fertilizer mixing tank.
[0012] The fertilizer suction pipe includes a first pipe and a second pipe. One end of the first pipe is connected to the main pipe, and the other end is connected to the fertilizer mixing tank. One end of the second pipe is connected to the first pipe through a Venturi jet. The second pipe is equipped with a fertilizer suction solenoid valve.
[0013] The detection pipeline has one end connected to the main pipeline and the other end connected to the fertilizer mixing tank. The detection pipeline is equipped with a detection sensor.
[0014] The operation console is connected to both the fertilizer suction solenoid valve and the detection sensor signal.
[0015] In this system, multiple fertilizer suction pipes are connected to external acid and nutrient solution, respectively, to transport the acid and nutrient solution to the fertilizer mixing tank. During use, external water is first introduced into the fertilizer mixing tank through the inlet pipe. When the water level in the mixing tank reaches a set value, the pump is activated, pumping the water from the mixing tank to the main pipe. A portion of the water in the main pipe flows back into the fertilizer mixing tank through the first pipe, forming a circulation. During this process, a Venturi jet injector uses the water pressure difference to generate negative pressure, attracting the acid and nutrient solution from the second pipe into the fertilizer mixing tank, achieving water-fertilizer mixing. Another portion of the water flows into the fertilizer mixing tank through a detection pipe. During this process, sensors detect the EC and pH values of the flowing liquid and transmit the data to the control console. When the EC and pH values of the flowing liquid deviate from the preset values, the control console automatically receives the data and sends a signal to adjust the opening and closing status of each fertilizer suction solenoid valve. By regulating the flow rate of the acid and nutrient solution, the precision of fertilizer mixing is controlled.
[0016] Optionally, a water outlet pipe is connected to the main pipeline, and a water outlet solenoid valve is installed on the water outlet pipe. The water outlet solenoid valve is signal-connected to the operation control console.
[0017] Once the EC and pH values in the fertilizer mixing tank reach the set values, the control console sends a signal to open the outlet solenoid valve. At this time, the fertilizer solution in the mixing tank is pumped into the main pipeline and then transported to the outside through the outlet pipeline, completing the fertilization process.
[0018] Optionally, the water inlet pipe is equipped with a float diaphragm valve, and the float of the float diaphragm valve is located inside the fertilizer mixing tank.
[0019] During startup, when the water level in the distribution tank is lower than the float height, the float diaphragm valve opens, allowing outside clean water to enter the fertilizer mixing tank. When the water level in the fertilizer mixing tank reaches the float diaphragm valve height, the float diaphragm valve closes. After fertilizer mixing is complete, as the fertilizer solution is discharged, the water level in the fertilizer mixing tank drops accordingly, triggering the float diaphragm valve to reopen, allowing water to flow into the fertilizer mixing tank again. As water is replenished, the detection pipeline detects a decrease in the EC value and an increase in the pH value of the fertilizer solution flowing through it, deviating from the preset values. The fertilizer suction solenoid valve then reopens, attracting external acid and nutrient solution into the fertilizer mixing tank, achieving continuous mixing and use of the fertilizer solution and improving fertilizer mixing efficiency.
[0020] Optionally, the fertilizer mixing tank is equipped with a level transmitter, which is signal-connected to the operation control console.
[0021] The liquid level in the fertilizer mixing tank is monitored in real time by a level transmitter. When the liquid level exceeds the set value range, the operation control console controls the pump to stop working.
[0022] Optionally, the detection pipeline is equipped with a first pressure reducing valve and a first pressure gauge, the first pressure reducing valve and the first pressure gauge being located between the detection sensor and the main pipeline;
[0023] The detection pipeline is also equipped with a first flow meter and a first flow regulating valve, which are located between the detection sensor and the fertilizer mixing tank.
[0024] In this scheme, a first pressure gauge is used to monitor the pressure in the pipeline in real time. Simultaneously, a first pressure-reducing valve is adjusted according to the pressure reading to prevent damage to the EC and pH sensors due to excessive pressure in the pipeline. Furthermore, a first flow meter continuously monitors changes in the flow rate in the pipeline, and a first flow regulating valve is used to precisely control the flow rate, thereby ensuring accurate detection results.
[0025] Optionally, a second pressure reducing valve and a second pressure gauge are provided on the main pipeline or the first pipeline. The second pressure gauge is used to monitor the flow pressure passing through the Venturi jet, and the second pressure reducing valve is used to adjust the flow pressure passing through the Venturi jet.
[0026] The flow rate and pressure through the Venturi jet are monitored using a second pressure gauge. At the same time, the second pressure reducing valve is adjusted in a timely manner based on the pressure reading to ensure the pressure of the Venturi jet is stable.
[0027] Optionally, a drainage pipe is connected to the bottom of the fertilizer mixing tank.
[0028] Optionally, a pressure transmitter is provided at one end of the main pipeline near the fertilizer suction pipeline, and the pressure transmitter is signal-connected to the operation control console.
[0029] The pressure transmitter can detect the pressure at the end of the main pipeline and transmit the detected data to the operation control console. When the detected pressure is lower than the set value, the operation control console can issue an alarm to prevent insufficient pressure in the fertilizer suction pipeline due to insufficient pressure in the main pipeline, thus preventing effective fertilizer suction.
[0030] Optionally, the second pipeline is equipped with a second flow meter and a second flow regulating valve.
[0031] Optionally, the outlet pipe is equipped with a back pressure valve and a sampling valve. The back pressure valve is used to stabilize the pressure upstream of the outlet pipe, ensuring that the fertilizer suction pipe has sufficient pressure for fertilizer suction. The sampling valve is located at the outlet of the outlet solenoid valve, allowing for manual sampling. By manually sampling and calibrating the output water-fertilizer mixture, the EC and pH values of the water-fertilizer solution in the integrated water-fertilizer machine can be more accurately controlled.
[0032] Compared with existing technologies, the beneficial effects achieved by this application are as follows: Multiple fertilizer suction pipes in this application are connected to external acid and nutrient solution respectively, transporting the acid and nutrient solution to the fertilizer mixing tank through these pipes. In use, external water is first introduced into the fertilizer mixing tank through the inlet pipe. Then, a pump transports the water in the fertilizer mixing tank to the main pipe. Part of the water in the main pipe flows back into the fertilizer mixing tank through the first pipe, forming a circulation. During this process, a Venturi jet injector uses the water pressure difference to generate negative pressure, attracting the acid and nutrient solution from the second pipe into the fertilizer mixing tank, achieving water-fertilizer mixing. Another portion of the water in the main pipe flows into the fertilizer mixing tank through a detection pipe. During this process, a detection sensor can detect the EC and pH values of the flowing liquid and transmit the data to the operation control console. When the EC and pH values of the flowing liquid deviate from preset values, the operation control console automatically receives the data and sends a signal to adjust the opening and closing status of each fertilizer suction solenoid valve, thereby achieving precise control of fertilizer mixing. Furthermore, the automated control significantly improves production efficiency, meeting the demands of modern agriculture for precision agriculture and high-efficiency production.

Detailed Implementation
[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0041] Example 1
[0042] This embodiment describes a water and fertilizer integrated machine device, referencing... Figure 1 and Figure 2The fertigation machine in this embodiment includes: a frame 1; the frame 1 serves as a supporting structure, ensuring that all structures can be stably and securely installed on it. A fertilizer mixing tank 2 is mounted on the frame 1, used for storing and mixing the fertigation solution. An inlet pipe 8 is connected to the fertilizer mixing tank 2. A pump 3 is also connected to the fertilizer mixing tank 2; in this embodiment, the pump 3 is a horizontal centrifugal pump. The inlet end of the horizontal centrifugal pump is connected to the fertilizer mixing tank 2, and the outlet end is connected to the main pipe 4. This embodiment also includes multiple fertilizer suction pipes 5, which are respectively connected to external acid and nutrient solution, transporting the acid and nutrient solution to the fertilizer mixing tank 2 through the fertilizer suction pipes 5. Further, each fertilizer suction pipe 5 includes a first pipe 51 and a second pipe 52. One end of the first pipe 51 is connected to the main pipe 4, and the other end is connected to the fertilizer mixing tank 2. One end of the second pipe 52 is connected to the first pipe 51 via a Venturi jet injector 53, and a fertilizer suction solenoid valve 521 is mounted on the second pipe 52. This example also uses the detection pipe 9 to control the precision of fertilizer application. Specifically, one end of the detection pipe 9 is connected to the main pipe 4, and the other end is connected to the fertilizer mixing tank 2. The detection pipe 9 is equipped with detection sensors 91. In this embodiment, the detection sensors 91 include an EC detection sensor 91 and a pH detection sensor 91. The EC and pH sensors 91 are used to detect the EC value (conductivity) and pH value (acidity / alkalinity) of the fertilizer solution. The EC value is used to measure the concentration of soluble salts in the solution, and can also be used to measure the concentration of soluble ions in liquid fertilizer or planting media. pH is an indicator of the acidity / alkalinity of the solution, and the pH value of irrigation water has a significant impact on crop growth. This embodiment also includes an operation control console 7, which can be automated using a PLC controller. The operation control console 7 is connected to the fertilizer suction solenoid valve 521 and the detection sensors 91.
[0043] In operation, external water is first introduced into the fertilizer mixing tank 2 through the inlet pipe 8. When the water level in the fertilizer mixing tank 2 reaches the set value, the horizontal centrifugal pump is activated, which transports the water in the fertilizer mixing tank 2 to the main pipe 4. Part of the water in the main pipe 4 flows back into the fertilizer mixing tank 2 through the first pipe 51, forming a circulation. During this process, the Venturi jet injector 53 uses the water pressure difference to generate negative pressure, attracting acid and nutrient solution from the second pipe 52 into the fertilizer mixing tank 2, achieving water-fertilizer mixing. Another part of the water flows into the fertilizer mixing tank 2 through the detection pipe 9. During this process, the detection sensor 91 can detect the EC value and pH value of the liquid flowing through it and transmit the data to the operation control console 7. When the EC value and pH value ratio of the liquid flowing through it deviates from the preset value, the operation control console 7 automatically receives the data and sends a signal to adjust the opening and closing status of each fertilizer suction solenoid valve 521. Through automated control, not only is the precision of fertilizer mixing controlled, but production efficiency is also improved.
[0044] In this embodiment, a water outlet pipe 6 is connected to the main pipe 4, and a water outlet solenoid valve 61 is installed on the water outlet pipe 6. The water outlet solenoid valve 61 is signal-connected to the operation control console 7. When the EC value and pH value in the fertilizer mixing tank 2 are detected to reach the set values, the operation control console 7 sends a signal to open the water outlet solenoid valve 61. At this time, the water-fertilizer solution in the fertilizer mixing tank 2 enters the main pipe 4 through a horizontal centrifugal pump and is then transported to the outside through the water outlet pipe 6, completing the fertilization process.
[0045] In this embodiment, a float diaphragm valve 81 is installed on the 8 inlet pipes, with the float of the float diaphragm valve 81 located inside the fertilizer mixing tank 2. During the startup phase, when the water level in the mixing tank is lower than the float height, the float diaphragm valve opens, allowing outside clean water to enter the fertilizer mixing tank 2. When the water level in the fertilizer mixing tank 2 reaches the float diaphragm valve height, the float diaphragm valve closes. After fertilizer mixing is completed, as the fertilizer solution is discharged, the liquid level in the fertilizer mixing tank 2 drops accordingly, triggering the float diaphragm valve to reopen. As water is replenished, the detection pipe 9 detects a decrease in the EC value and an increase in the pH value of the fertilizer solution flowing through it, causing the fertilizer suction solenoid valve 521 to reopen. This enables continuous mixing and use of the fertilizer solution, improving fertilizer mixing efficiency.
[0046] Example 2:
[0047] Based on the same inventive concept as Embodiment 1, refer to Figures 1 to 3 In this embodiment, a level transmitter 21 is installed inside the fertilizer mixing tank 2, and the level transmitter 21 is connected to the operation control console 7. The level transmitter 21 monitors the liquid level in the fertilizer mixing tank 2 in real time. When the liquid level exceeds the set value, the operation control console 7 controls the pump 3 to stop working. Furthermore, the bottom of the fertilizer mixing tank 2 is connected to a drain pipe 22 for convenient drainage and cleaning.
[0048] refer to Figure 4 In this embodiment, the detection pipeline 9 is equipped with a first pressure reducing valve 92 and a first pressure gauge 93, located between the detection sensor 91 and the main pipeline 4. The detection pipeline 9 is also equipped with a first flow meter 94 and a first flow regulating valve 95, located between the detection sensor 91 and the fertilizer mixing tank 2. The first pressure gauge 93 monitors the pressure within the detection pipeline 9 in real time. Simultaneously, the first pressure reducing valve 92 adjusts according to the pressure reading to prevent damage to the EC and pH detection sensors 91 due to excessive pressure within the pipeline. Furthermore, the first flow meter 94 continuously monitors changes in flow rate within the pipeline, and the first flow regulating valve 95 precisely controls the flow rate, thereby ensuring accurate detection results.
[0049] To ensure stable pressure in the Venturi jet injector 53, in this embodiment, a second pressure-reducing valve 41 and a second pressure gauge 42 are provided on the main pipe 4 or the first pipe 51. The second pressure gauge 42 is used to monitor the flow pressure passing through the Venturi jet injector 53, and the second pressure-reducing valve 41 is used to regulate the flow pressure passing through the Venturi jet injector 53. By using the second pressure gauge 42 to monitor the flow pressure passing through the Venturi jet injector 53, and simultaneously adjusting the second pressure-reducing valve 41 according to the pressure reading, the pressure in the Venturi jet injector 53 is ensured to be stable.
[0050] Furthermore, a pressure transmitter 43 is installed at the end of the main pipeline 4 near the fertilizer suction pipeline 5, and the pressure transmitter 43 is signal-connected to the operation control console 7. The pressure transmitter 43 can detect the pressure at the tail end of the main pipeline 4 and transmit the detected data to the operation control console 7. When the detected pressure is lower than the set value, the operation control console 7 can issue an alarm to prevent insufficient pressure in the fertilizer suction pipeline 5 due to insufficient pressure in the main pipeline 4, thus preventing effective fertilizer suction. Furthermore, a second flow meter 522 and a second flow regulating valve 523 are installed on the second pipeline 52. The flow rate of acid and nutrient solution in the second pipeline 52 is monitored and regulated through the second flow meter 522 and the second regulating valve.
[0051] refer to Figure 5 When the outlet solenoid valve 61 opens, the water pressure in the main pipe 4 will decrease, resulting in insufficient pressure in the fertilizer suction pipe 5. To avoid this problem, in this embodiment, a back pressure valve 62 is provided on the outlet pipe 6. The back pressure valve 62 can stabilize the pressure upstream of the outlet pipe 6, ensuring that the fertilizer suction pipe 5 has sufficient pressure for fertilizer suction.
[0052] Furthermore, a sampling valve 63 is also provided at the outlet of the water solenoid valve 61. Manual sampling can be performed through the sampling valve 63. By manually sampling and calibrating the output water-fertilizer mixture, the EC value and pH value of the water-fertilizer solution in the water-fertilizer integrated machine can be controlled more accurately.
[0053] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
