Description

Technical Field

[0001] The present application generally relates to the field of agricultural intelligent equipment engineering, and specifically relates to a pesticide dilution and mixing system that can be used for the dilution and mixing of pesticides during conventional pesticide spraying or aerial application. Background Art

[0002] The use of chemical or biological pesticides to protect crop growth has become a key feature of modern agricultural production and a crucial technology for increasing agricultural yields and reducing food production costs. Pesticide dilution and mixing are crucial components of plant protection technology. Maintaining precise dilution concentrations and uniform mixing reduces manual labor and ensures uniform spraying of pesticides across the crop surface, protecting the crops without causing any harm, ultimately promoting healthy crop growth.

[0003] Plant protection technology is a comprehensive approach designed to prevent and control the occurrence and spread of plant diseases, insects, and weeds, thereby protecting plant health and safety. Pesticide blending involves mixing two or more pesticides in a specific dosage and sequence. Compared to using a single pesticide, blending two or more pesticides can expand the control spectrum, reduce the risk of pesticide resistance, and reduce the number of applications, saving manpower and resources.

[0004] However, currently most pesticide dilution and mixing are done manually, which is not only time-consuming and labor-intensive, but also easily causes direct contact between the human body and the pesticides during the dilution and mixing process, causing a certain degree of harm to the human body. Utility Model Content

[0061] The dilution and mixing of pesticides, such as pesticides, is an important part of plant protection technology. Maintaining accurate dilution concentration and uniform mixing reduces manual operation and ensures that the pesticide is evenly sprayed on the crop surface. This protects the crops without causing any damage, thus promoting their healthy growth.

[0062] The pesticide dilution and mixing technology is to dilute and mix two or more pesticides in a certain dosage and sequence. Compared with the use of a single pesticide, mixing two or more pesticides can expand the prevention and control spectrum, reduce the risk of pesticide resistance, and also reduce the number of spraying times, saving manpower and material resources.

[0063] When diluting a drug, a single dilution may not achieve a good dilution effect. For example, the drug may not be fully mixed with water, and a uniformly diluted drug cannot be formed. According to some embodiments of the present application, a secondary dilution of the drug, namely a primary dilution and a secondary dilution, can achieve a good dilution effect on the one hand, and also facilitate subsequent mixing operations on the other hand, providing a good foundation for uniform mixing.

[0064] When mixing pharmaceuticals, directly mixing multiple pharmaceuticals may not be able to achieve good mixing uniformity. For example, pharmaceuticals with high concentrations may be difficult to mix with each other, resulting in an uneven final mixture. According to some embodiments of the present application, the pharmaceuticals are first diluted individually, and then the initially diluted pharmaceuticals are mixed together for further dilution and mixing. This can achieve a uniform mixture, so that the pharmaceuticals ultimately reach the desired concentration and uniformity.

[0065] Furthermore, currently, most drug dilution and mixing processes are performed manually, which is not only time-consuming and labor-intensive, but also easily causes direct contact between the human body and the drug during the dilution and mixing process, causing a certain degree of harm to the human body. Therefore, the drug dilution and mixing system and method according to the present application use a controller to control the operation of each module of the drug dilution and mixing system, achieving automated operation, reducing the probability of drug contact with the human body and causing harm, and at the same time, more precisely controlling the accuracy of dilution and mixing compared to manual dilution and mixing.

[0066] The following will describe in detail a drug dilution and mixing system and method according to some embodiments of the present application with reference to the accompanying drawings. Figure 1-4 1 and 2 respectively show a perspective view, a front view, a top view and a side view of a pharmaceutical dilution and mixing system 1 according to some embodiments of the present application.

[0067] like Figure 1 As shown, the agent dilution and mixing system 1 is used to dilute and mix agents such as pesticides. In order to facilitate mobile operations, the agent dilution and mixing system 1 may include a mobile platform 10, and the various components of the agent dilution and mixing system 1 may be arranged on the mobile platform 10. The mobile platform 10 may include rollers 12 and a mobile body 14. The rollers 12 may be arranged at the bottom of the mobile body 14 to facilitate the movement of the mobile platform 10 to the position where the operation is to be performed. The mobile body 14 may be in the form of a frame structure, for example, and may be enclosed on three sides with transparent glass to facilitate observation of the operation of the agent dilution and mixing system 1, with a double sliding door 142 (such as Figure 4 To facilitate manual intervention by the operator, a latch is provided at the bottom of the sliding door 142 for securing it during movement. In some embodiments, mounting brackets are provided around and above the mobile platform for mounting baffles. A handrail 144 may also be provided on one side of the mobile body 14 to facilitate the operator's movement of the pharmaceutical dilution and mixing system 1.

[0068] According to some embodiments of the present application, the drug dilution and mixing system 1 may include a controller 16, which is configured to control the operation of each module in the drug dilution and mixing system 1. The controller 16 may be provided on the mobile body 14, for example, installed at the bottom of the mobile body 14, such as Figure 1-4 In some embodiments, the controller 16 can be housed in a control box to protect the controller. The connection and communication between the controller 16 and each component to be controlled will be described below.

[0069] According to some embodiments of the present application, Figure 1-4 As shown, the drug dilution and compounding system 1 may include a primary dilution module 20 and a secondary dilution and compounding module 30. The primary dilution module 20 and the secondary dilution and compounding module 30 communicate with the controller 16, and the operations of the primary dilution module 20 and the secondary dilution and compounding module 30 are controlled by the controller 16. The primary dilution module 20 may include a dilution tank 22 and is configured to perform primary dilution on the drug in the dilution tank 22 to form a primary diluted drug. The secondary dilution and compounding module 30 may include a mixing tank 32, which is fluidically connected to the dilution tank 22 of the primary dilution module 20. The secondary dilution and compounding module 30 may be configured to receive the primary diluted drugs from the primary dilution module 20. Each primary diluted drug may be secondary diluted and mixed in the mixing tank 32 to form a secondary mixed drug.

[0070] The drug dilution and mixing system 1 according to the present application adopts a two-stage dilution mode, i.e., the drug is primarily diluted in the primary dilution module 20 to form a primary diluted drug, and the primary diluted drug is further secondary diluted in the secondary dilution and mixing module 30. The two-stage dilution mode facilitates the dilution of the drug and can achieve a better dilution effect than a single direct dilution. It also facilitates subsequent mixing using the diluted drug.

[0071] According to some embodiments of the present application, the primary dilution module 20 may be configured to perform primary dilution on each of the multiple medicines individually, and to separately deliver the primary diluted medicine formed by each medicine to the mixing kettle 32 of the secondary dilution and mixing module 30. Specifically, one medicine undergoes primary dilution in the primary dilution module 20, and the resulting primary diluted medicine is delivered to the secondary dilution and mixing module 30. Then, another medicine undergoes primary dilution in the primary dilution module 20, and the resulting primary diluted medicine is delivered to the secondary dilution and mixing module 30. This process is repeated until all medicines have formed their own primary diluted medicines and are respectively delivered to the secondary dilution and mixing module 30.

[0072] This method of first diluting each agent separately and then mixing them avoids the problem of multiple high-concentration agents being difficult to mix evenly with each other when they are directly mixed. Each agent is first diluted separately, and then the diluted agents are further diluted and mixed, which helps to obtain a mixed agent with good uniformity.

[0073] Combined with reference Figure 6 , which shows a schematic diagram of a dilution kettle 22 according to some embodiments of the present application. The dilution kettle 22 may include a kettle-shaped body 222. Mounting blocks 224 may be provided on the outer periphery of the body 222. The dilution kettle 22 may be fixedly mounted to the dilution kettle bracket 146 of the mobile body 14 of the mobile platform 10 via the mounting blocks 224.

The mixing kettle 32 may be fixedly mounted to the mixing kettle bracket 148 of the mobile body 14 of the mobile platform 10 via the mounting blocks 324. In the illustrated embodiment, three evenly spaced mounting blocks 324 are disposed on the outer periphery of the body 322. This is merely exemplary, and those skilled in the art will appreciate that the number and arrangement of the mounting blocks 324 are not limited thereto.

[0075] According to some embodiments of the present application, the primary dilution module 20 includes a primary stirring device 24, which includes a motor 242 and a stirring element 248. The motor 242 is coupled to the stirring element 248 and drives the stirring element 248 to rotate so as to stir the primary diluted medicament formed in the dilution tank 22. The motor 242 can communicate with the controller 16 so as to be started and stopped by the controller 16.

[0076] exist Figure 6 In the illustrated embodiment, a motor 242 may be disposed at the top portion 226 of the dilution tank 22. A coupling 244 is coupled to the output end of the motor 242, a driven shaft 246 is coupled to the coupling 244, and a stirring element 248 may be disposed on the driven shaft 246, whereby the motor 242 drives the stirring element 248 to rotate via the coupling 244 and the driven shaft 246. The motor 242 may extend outside the main body 222 of the dilution tank 22, the coupling 244 may be disposed on the top portion 226 of the dilution tank 22 and extend into the dilution tank 22, and the driven shaft 246 and the stirring element 248 may be located within the dilution tank 22 to facilitate stirring of the primary dilution agent within the dilution tank 22.

[0077] According to some embodiments of the present application, Figure 6 As shown, the stirring element 248 may include a propeller stirring paddle 248A and / or an anchor stirring paddle 248B. Depending on the needs of the actual application, the stirring element 248 may be in the form of a single stirring paddle or a plurality of stirring paddles acting together. In the illustrated embodiment, the propeller stirring paddle 248A is located above the anchor stirring paddle 248B, and the anchor stirring paddle 248B is located near the bottom of the dilution tank 22. The combination of the propeller stirring paddle 248A and the anchor stirring paddle 248B facilitates sufficient stirring of the primary dilution agent in the dilution tank 22, preventing the agent from settling at the bottom of the dilution tank 22.

[0078] According to some embodiments of the present application, the secondary dilution and mixing module 30 includes a secondary stirring device 34, which includes a motor 342 and a stirring element 348. The motor 342 is coupled to the stirring element 348 and drives the stirring element 348 to rotate so as to stir the secondary mixed pharmaceutical formed in the mixing tank 32. The motor 342 can communicate with the controller 16 so as to be started and stopped by the controller 16.

[0079] exist Figure 7 In the illustrated embodiment, a motor 342 may be disposed at the top portion 326 of the mixing kettle 32. A coupling 344 may be coupled to the output end of the motor 342, a driven shaft 346 may be coupled to the coupling 344, and a stirring element 348 may be disposed on the driven shaft 346, whereby the motor 342 drives the stirring element 348 to rotate via the coupling 344 and the driven shaft 346. The motor 342 may extend outside the main body 322 of the mixing kettle 32, the coupling 344 may be disposed on the top portion 326 of the mixing kettle 32 and extend into the mixing kettle 32, and the driven shaft 346 and the stirring element 348 may be located within the mixing kettle 32 to facilitate stirring of the secondary mixed reagent within the mixing kettle 32.

[0080] According to some embodiments of the present application, Figure 7 As shown, the stirring element 348 may include a propeller stirring paddle 348A and / or an anchor stirring paddle 348B. Depending on the needs of the actual application, the stirring element 348 may be in the form of a single stirring paddle or in the form of multiple stirring paddles acting together. In the illustrated embodiment, the propeller stirring paddle 348A is located above the anchor stirring paddle 348B, and the anchor stirring paddle 348B is located near the bottom of the mixing kettle 32. The combination of the propeller stirring paddle 348A and the anchor stirring paddle 348B facilitates sufficient stirring of the secondary mixed reagents in the mixing kettle 32, preventing the reagents from settling at the bottom of the mixing kettle 32.

[0081] According to some embodiments of the present application, Figure 2As shown, the dilution tank 22 of the primary dilution module 20 can be connected to the mixing tank 32 of the secondary dilution mixing module 30 through a connecting pipe 23. A delivery valve 231 (see FIG. Figure 4 ), the transfer valve 231 is configured to open and close the fluid communication between the dilution tank 22 and the mixing tank 32.

[0082] An output port (not shown) may be formed at the bottom of the main body 222 of the dilution tank 22, to which the connecting pipe 23 is connected. An input port 328 may be formed, for example, at the top portion 326 of the compounding tank 32, to which the connecting pipe 23 is connected. Thus, the connecting pipe 23 connects the dilution tank 22 and the compounding tank 32 via the output port of the dilution tank 22 and the input port 328 of the compounding tank 32, thereby fluidly connecting the dilution tank 22 and the compounding tank 32 to each other.

[0083] like Figure 2 As shown, in some embodiments, the dilution tank 22 can be placed at a higher position than the mixing tank 32, so that the output port of the dilution tank 22 is higher than the input port 328 of the mixing tank 32. In this way, the liquid in the dilution tank 22 can flow into the mixing tank 32 through the connecting pipe 23 by gravity.

[0084] The delivery valve 231 can be, for example, a solenoid valve and is communicatively coupled to the controller 16 so that the controller 16 controls the opening and closing of the delivery valve 231. When the delivery valve 231 is open, the liquid in the dilution tank 22 can flow into the mixing tank 32 via the connecting pipe 23. When the delivery valve 231 is closed, the liquid in the dilution tank 22 is retained and cannot flow into the mixing tank 32.

[0085] According to some embodiments of the present application, Figure 1-5 As shown, the drug dilution and compounding system 1 may further include a drug adding module 40 , which is fluidically connected to the dilution tank 22 of the primary dilution module 20 and configured to individually deliver each of the multiple drugs into the dilution tank 22 .

[0086] Specifically, the dosing module 40 delivers one drug at a time to the dilution tank 22. After the drug is diluted in the dilution tank 22 to form a primary diluted drug, which is then delivered to the mixing tank 32, the next drug is delivered. In this way, the dosing module 40 can provide separate delivery of drugs during the dosing stage before dilution, avoiding mixed dilution of drugs and facilitating subsequent dilution and mixing operations.

[0087] According to some embodiments of the present application, the dosing module 40 may include a dosing cartridge 42 and a metering pump 44. The dosing cartridge 42 contains a medicament and is fluidically connected to the dilution tank 22 of the primary dilution module 20 via the metering pump 44. The metering pump 44 is configured to pump the medicament from the dosing cartridge 42 to the dilution tank 22 and can control the amount of the medicament pumped from the dosing cartridge 42 to the dilution tank 22. The metering pump 44 can be communicatively coupled to the controller 16, and the controller 16 controls the operation of the metering pump 44, such as controlling the start and stop of the metering pump 44 to control the pumping amount of the metering pump 44.

[0088] According to some embodiments of the present application, Figure 5 As shown, the dosing module 40 may include at least one dosing cartridge 42. For example, in the illustrated embodiment, four dosing cartridges 42 are provided. The number of dosing cartridges 42 may be determined based on actual application needs, for example, corresponding to the number of medicaments to be mixed. Each dosing cartridge 42 contains a single medicament, thereby conveniently controlling the delivery of each medicament.

[0089] The dosing module 40 may include a flushing cylinder 46 that contains flushing water for flushing certain parts of the dosing module 40 after dosing. The flushing cylinder 46 may be arranged side by side with the dosing cylinder 42, such as Figure 5 shown.

[0090] The dosing module 40 may include a connector 48 through which the dosing cartridge 42 and the flushing cartridge 46 are connected to the metering pump 44. The connector 48 may include a plurality of input ports 482 and output ports 484. The number of input ports 482 may correspond to the number of dosing cartridges 42 and the flushing cartridge 46. In the illustrated embodiment, the connector 48 has five input ports 482, such as Figure 5 As shown in the dotted circle portion, there are four dosing cartridges 42 and one flushing cartridge 46. Each of the at least one dosing cartridge 42 is connected to a corresponding input port 482 of the plurality of input ports 482 via a corresponding first tube 422. The flushing cartridge 46 is connected to a corresponding input port 482 of the plurality of input ports 482 via a second tube 462.

[0091] The metering pump 44 is connected to the output port 484 of the connector 48 and is connected to the dilution tank 22 of the primary dilution module 20 through the third pipe 442. The metering pump 44 is configured to pump the drug from the dosing cartridge 42 to the dilution tank 22 and can control the amount of the drug pumped from the dosing cartridge 42 to the dilution tank 22. In addition, the metering pump 44 can also be configured to pump flushing water from the flushing cartridge 46 to the dilution tank 22.

[0092] The medicine contained in the dosing cartridge 42 can pass through the first pipe 422 and the joint 48 to the metering pump 44, and is pumped by the metering pump 44 into the dilution tank 22 through the third pipe 442. Similarly, the flushing water contained in the flushing cartridge 46 can pass through the second pipe 462 and the joint 48 to the metering pump 44, and is pumped by the metering pump 44 into the dilution tank 22 through the third pipe 442.

[0093] According to some embodiments of the present application, a first valve 424 may be provided on the first tube 422. The first valve 424 may be a solenoid valve configured to open and close the fluid communication between the dosing cartridge 42 and the metering pump 44. The first valve 424 may be in communication with the controller 16, and the opening and closing of the first valve 424 may be controlled by the controller 16. When the first valve 424 is open, the drug in the dosing cartridge 42 may flow to the metering pump 44 via the first tube 422. When the first valve 424 is closed, the drug in the dosing cartridge 42 cannot flow to the metering pump 44.

[0094] In some embodiments, the second tube 462 may also be provided with a second valve 464, which may be a solenoid valve and configured to open and close the fluid communication between the flushing cylinder 46 and the metering pump 44. The second valve 464 may be in communication with the controller 16, and the opening and closing of the second valve 464 may be controlled by the controller 16. When the second valve 464 is open, flushing water in the flushing cylinder 46 may flow to the metering pump 44 via the second tube 462. When the second valve 464 is closed, flushing water in the flushing cylinder 46 cannot flow to the metering pump 44.

[0095] According to some embodiments of the present application, the dosing module 40 may be configured to pump flushing water from a flushing cylinder 46 to the dilution tank 22 via the metering pump 44 after the drug in each of the at least one dosing cartridge 42 is pumped into the dilution tank 22 via the metering pump 44. In this way, after a drug is delivered to the dilution tank 22, at least the metering pump 44 and the third pipe 442 may be flushed with flushing water, and the drug remaining in the metering pump 44 and the third pipe 442 may be flushed into the dilution tank 22.

[0096] Taking a dosing cartridge 42 as an example, when dosing is required, the first valve 424 corresponding to the dosing cartridge 42 is opened, allowing the drug to flow from the dosing cartridge 42 through the first tube 422 to the metering pump 44. The metering pump 44 determines the predetermined amount of drug to be pumped. When the drug passing through the metering pump 44 reaches the predetermined amount, the first valve 424 is closed and the metering pump 44 is stopped. At this point, the predetermined amount of drug is transported to the dilution tank 22 through the third tube 442. However, it is generally unavoidable that some drug will remain in, for example, the metering pump 44 and the third tube 442. This portion of drug has actually been metered by the metering pump 44 and should be counted towards the predetermined amount of drug. To this end, according to some embodiments of the present application, the metering pump 44 and the third tube 442 can be flushed with flushing water. Specifically, opening second valve 464 allows flushing water to flow from flushing cylinder 46 through second tube 462 to metering pump 44. Metering pump 44 then delivers the flushing water through third tube 442 to dilution tank 22. During this process, the flushing water flushes any remaining medication in metering pump 44 and third tube 442 into dilution tank 22, ensuring that the actual amount of medication entering dilution tank 22 roughly corresponds to the predetermined amount, significantly improving medication dosing accuracy. In some embodiments, metering pump 44 can be positioned as close to connector 48 as possible to further reduce medication delivery errors and improve medication dosing accuracy.

[0097] According to some embodiments of the present application, the pesticide dilution and mixing system 1 may further include an output module 50, which is configured to discharge the secondary mixed pesticide from the secondary dilution and mixing module 30. The secondary mixed pesticide discharged from the secondary dilution and mixing module 30 may be transferred to a work box for subsequent use in pesticide application, or may be directly used for application through the output module 50, for example, by spraying the pesticide directly onto crops.

[0098] According to some embodiments of the present application, Figure 2-4 As shown, the output module 50 may include an output pump 52 and an output gun 54. The output pump 52 is connected to the output port (not shown) of the mixing tank 32 of the secondary dilution mixing module 30 through a discharge pipe 522, and the output gun 54 is connected to the output pump 52 through an output pipe 542. In this way, the secondary mixed reagent from the mixing tank 32 is discharged from the output gun 54 through the discharge pipe 522, via the output pump 52, and through the output pipe 542.

[0099] According to some embodiments of the present application, Figure 1-4 As shown, the drug dilution and mixing system 1 may further include a water supply module 60, which is configured to supply water at least to the primary dilution module 20 and the secondary dilution and mixing module 30. In addition, the water supply module 60 may also be configured to supply flushing water to the flushing cylinder 46 in the dosing module 40.

[0100] According to some embodiments of the present application, the water supply module 60 may include a water supply pump 61, a main pipeline 62, and a dilution pipeline 64 and a mixing pipeline 66 fluidically connected to the main pipeline 62. The water supply pump 61 is connected to a water supply source (not shown) and the main pipeline 62 to pump water from the water supply source into the main pipeline 62 to be used for supplying water for the operation of the pharmaceutical dilution and mixing system 1. The water supply pump 61 is communicatively connected to the controller 16, and the controller 16 controls the start and stop of the water supply pump 61.

[0101] The dilution pipe 64 is fluidically connected to the dilution tank 22 of the primary dilution module 20 for delivering water to the dilution tank 22. In some embodiments, the water delivered to the dilution tank 22 by the dilution pipe 64 can be used to dilute the medicine in the dilution tank 22 or to clean the dilution tank 22.

[0102] In a further embodiment, the dilution line 64 may include a dilution water replenishment line 642 and a dilution cleaning line 644 to replenish dilution water and supply cleaning water to the dilution tank 22, respectively. The dilution water replenishment line 642 may be connected to the water replenishment port 230 on the dilution tank 22 (e.g., the top portion 226 thereof) to deliver dilution water to the dilution tank 22 through the water replenishment port 230 to dilute the agent. The dilution cleaning line 644 may be connected to the cleaning port 232 on the dilution tank 22 (e.g., the top portion 226 thereof) to deliver cleaning water to the dilution tank 22 through the cleaning port 232 to clean the dilution tank 22. In some embodiments, a primary cleaning device 234 may be provided in the dilution tank 22. The primary cleaning device 234 may be in the form of a 360° spray ball and is fluidically connected to the dilution cleaning pipe 644 via the cleaning port 232. Cleaning water is delivered to the primary cleaning device 234 via the dilution cleaning pipe 644 and the cleaning port 232. The primary cleaning device 234 then uses the cleaning water to clean the dilution tank 22.

[0103] Similarly, the mixing pipe 66 is fluidically connected to the mixing tank 32 of the secondary dilution mixing module 30 for delivering water to the mixing tank 32. In some embodiments, the water delivered to the mixing tank 32 by the mixing pipe 66 can be used to dilute and mix the reagents in the mixing tank 32, and can also be used to clean the mixing tank 32.

[0104] In further embodiments, the mixing conduit 66 may include a mixing water replenishment conduit 662 and a mixing and cleaning conduit 664 to replenish mixing water and supply cleaning water to the mixing kettle 32, respectively. The mixing water replenishment conduit 662 may be connected to a water replenishment port 330 on the mixing kettle 32 (e.g., the top portion 226 thereof) to deliver mixing water to the mixing kettle 32 through the water replenishment port 330 for diluting and mixing the reagents. The mixing and cleaning conduit 664 may be connected to a cleaning port 332 on the mixing kettle 32 (e.g., the top portion 226 thereof) to deliver cleaning water to the mixing kettle 32 through the cleaning port 332 for cleaning the mixing kettle 32. In some embodiments, a secondary cleaning device 334 may be provided in the mixing kettle 32. The secondary cleaning device 334 may be in the form of a 360° spray ball and is fluidically connected to the mixing and cleaning pipe 664 via the cleaning port 332, so that cleaning water is transported to the secondary cleaning device 334 via the mixing and cleaning pipe 664 and through the cleaning port 332, and then the secondary cleaning device 334 uses the cleaning water to clean the mixing kettle 32.

[0105] According to some embodiments of the present application, a dilution valve 643 may be provided on the dilution water supply pipe 642. The dilution valve 643 may be a solenoid valve and is communicatively coupled to the controller 16. The opening and closing of the dilution valve 643 is controlled by the controller 16. When the dilution valve 643 is open, the water supply pump 61 pumps the dilution water into the dilution tank 22. When the dilution valve 643 is closed, the dilution water cannot enter the dilution tank 22. A purge valve 645 may be provided on the dilution purge pipe 644. The purge valve 645 may be a solenoid valve and is communicatively coupled to the controller 16. The opening and closing of the purge valve 645 is controlled by the controller 16. When the purge valve 645 is open, the water supply pump 61 pumps the purge water into the dilution tank 22. When the purge valve 645 is closed, the purge water cannot enter the dilution tank 22.

[0106] Similarly, a mixing valve 663 may be provided on the mixing water supply pipe 662. The mixing valve 663 may be a solenoid valve and is in communication with the controller 16. The opening and closing of the mixing valve 663 is controlled by the controller 16. When the mixing valve 663 is open, the water supply pump 61 pumps the mixed water into the mixing kettle 32. When the mixing valve 663 is closed, the mixed water cannot enter the mixing kettle 32. A cleaning valve 665 may be provided on the mixing cleaning pipe 664. The cleaning valve 665 may be a solenoid valve and is in communication with the controller 16. The opening and closing of the cleaning valve 665 is controlled by the controller 16. When the cleaning valve 665 is open, the water supply pump 61 pumps the cleaning water into the mixing kettle 32. When the cleaning valve 665 is closed, the cleaning water cannot enter the dilution kettle 32.

[0107] According to some embodiments of the present application, the pharmaceutical dilution and compounding system 1 may further include a monitoring module 70 , which may be configured to detect changes in the contents of the dilution tank 22 and the compounding tank 32 .

[0108] The monitoring module 70 may include a dilution tank monitoring device configured to monitor the contents (e.g., medication, water, etc.) entering the dilution tank 22. In some embodiments, the dilution tank monitoring device includes weight sensors 72 disposed around the dilution tank 22 and configured to monitor changes in the weight of the dilution tank 22. In the illustrated embodiment, three weight sensors 72 are evenly spaced around the periphery of the dilution tank 22. When a substance (e.g., medication, water, etc.) enters the dilution tank 22, the overall weight of the dilution tank 22 changes. This change is detected by the weight sensors 72 and determined as the amount (e.g., mass) of the substance entering the dilution tank 22. For example, when water is added to the dilution tank 22, the amount of water entering the dilution tank 22 can be controlled by the weight change of the dilution tank 22 detected by the weight sensors 72. The weight sensors 72 are communicatively coupled to the sensor 16 to transmit a signal of the detected weight change to the controller 16.

[0109] Similarly, the monitoring module 70 may include a mixing kettle monitoring device configured to monitor the contents (e.g., primary diluent, water, etc.) entering the mixing kettle 32. In some embodiments, the mixing kettle monitoring device includes weight sensors 74 disposed around the mixing kettle 32 and configured to monitor changes in the weight of the mixing kettle 32. In the illustrated embodiment, three weight sensors 74 are evenly spaced around the periphery of the mixing kettle 32. When a substance (e.g., a drug, water, etc.) enters the mixing kettle 32, the overall weight of the mixing kettle 32 changes. This change is detected by the weight sensors 74 and determined as the amount (e.g., mass) of the substance entering the mixing kettle 32. For example, when water is added to the mixing kettle 32, the amount of water entering the mixing kettle 32 can be controlled by the weight change of the mixing kettle 32 detected by the weight sensors 74. The weight sensors 74 are communicatively coupled to the sensor 16 to transmit a signal of the detected weight change to the controller 16.

[0110] The following will refer to Figure 8-10 , a detailed description of a pharmaceutical dilution and mixing method according to some embodiments of the present application is provided. The pharmaceutical dilution and mixing method can employ the pharmaceutical dilution and mixing system 1 according to some embodiments of the present application as described above.

[0111] According to some embodiments of the present application, Figure 8 As shown, the drug dilution and mixing method may include the following steps:

[0112] A pharmaceutical dilution and mixing system is provided, which includes a primary dilution module having a dilution kettle and a secondary dilution and mixing module having a mixing kettle;

[0113] A primary dilution process, wherein the reagent is primarily diluted in a dilution tank to form a primary diluted reagent, and the primary diluted reagent is transported to a mixing tank; and

[0114] The secondary dilution and mixing process is to conduct secondary dilution and mixing of the primary dilution agent in a mixing kettle to form a secondary mixed agent.

[0115] refer to Figure 8 At step S10, a pharmaceutical dilution and mixing system 1 is provided. The pharmaceutical dilution and mixing system 1 may be the pharmaceutical dilution and mixing system 1 according to some embodiments of the present application as described above. The pharmaceutical dilution and mixing system 1 includes a primary dilution module 20 having a dilution tank 22 and a secondary dilution and mixing module 30 having a mixing tank 32. The subsequent steps of the pharmaceutical dilution and mixing method are performed using the pharmaceutical dilution and mixing system 1.

[0116] At step S30, a primary dilution process is performed. Specifically, the dosing module 40 can be used to deliver the agent to the dilution tank 22 for primary dilution to form a primary diluted agent, and the formed primary diluted agent is delivered to the mixing tank 32 for subsequent further dilution and mixing steps in the mixing tank 32.

[0117] According to some embodiments of the present application, each of the multiple pharmaceutical agents is individually primary diluted in the dilution tank 22, and the primary diluted pharmaceutical agent formed by each pharmaceutical agent is individually transported to the mixing tank 32. Specifically, one pharmaceutical agent is primarily diluted in the primary dilution module 20, and the resulting primary diluted pharmaceutical agent is transported to the secondary dilution mixing module 30. Then, another pharmaceutical agent is primarily diluted in the primary dilution module 20, and the resulting primary diluted pharmaceutical agent is transported to the secondary dilution mixing module 30. This process is repeated until all pharmaceutical agents have each formed a primary diluted pharmaceutical agent and are respectively transported to the secondary dilution mixing module 30.

[0118] As mentioned above, this method of first diluting separately and then mixing avoids the problem that multiple high-concentration drugs are difficult to mix evenly with each other when they are directly mixed. Each drug is first diluted separately, and then the diluted drugs are further diluted and mixed, which helps to obtain mixed drugs with good uniformity.

[0119] Continue to refer Figure 8 At step S50, a secondary dilution and mixing process is performed to dilute and mix all the primary dilution agents from the dilution tank 22 in the mixing tank 32 to form a secondary mixed agent. The secondary mixed agent can be a final product that can be used, for example, to perform spraying operations on crops.

[0120] According to some embodiments of the present application, the primary dilution process is repeated for multiple reagents until the primary diluted reagents formed by all reagents enter the mixing tank, and then the secondary dilution and mixing process is performed. In this way, each reagent is first diluted into the primary diluted reagent in the dilution tank 22 and transported to the mixing tank 32. After all reagents have completed the primary dilution and entered the mixing tank 32, further dilution and mixing are performed in the mixing tank 32.

[0121] According to some embodiments of the present application, the agent dilution and mixing method may further include: after forming a secondary mixed agent in the mixing kettle, discharging the secondary mixed agent from the mixing kettle through an output module.

[0122] Specifically, if Figure 8 As shown, at step S70, the secondary mixed agent is discharged from the mixing tank 32 via the output module 50. The secondary mixed agent discharged from the secondary dilution and mixing module 30 can be transferred to a process tank for subsequent use in the application of the agent, or it can be directly applied through the output module 50, such as by spraying the agent directly onto crops. For example, the secondary mixed agent from the mixing tank 32 is discharged through the discharge pipe 522 of the output module 50, via the output pump 52, and through the output pipe 542 from the output gun 54 for direct application onto crops.

[0123] According to some embodiments of the present application, the reagent dilution and mixing method may further include: after the secondary mixed reagent is discharged from the mixing kettle via the output module, injecting cleaning water into the mixing kettle via the water supply module to clean the mixing kettle, and then draining the cleaning water from the mixing kettle after the cleaning of the mixing kettle is completed. In some embodiments, the amount of cleaning water can be controlled by the time the water supply module injects water. In some embodiments, cleaning the mixing kettle may further include: stirring the cleaning water in the mixing kettle using a stirring device.

[0124] Specifically, if Figure 8 As shown, in step S90, the mixing kettle 32 is cleaned by the water supply module 60. The following describes the process of cleaning the mixing kettle 32 by the water supply module 60 with respect to a specific embodiment. Those skilled in the art will appreciate that some steps in this specific embodiment may be optional and may be modified, changed, or combined to form new technical solutions without departing from the spirit and scope of the present application.

[0125] After the secondary mixed reagent is discharged from the mixing kettle 32 via the output module 50, cleaning of the mixing kettle 32 can begin. The controller 16 opens the cleaning valve 665 provided on the mixing cleaning pipe 664 and activates the water supply pump 61. The water supply pump 61 pumps cleaning water through the main pipe 62 and the mixing cleaning pipe 664 into the mixing kettle 32 to clean the mixing kettle 32. In some embodiments, the cleaning water can be delivered via the mixing cleaning pipe 664 and through the cleaning port 332 to the secondary cleaning device 334, which then uses the cleaning water to clean the mixing kettle 32. Furthermore, while cleaning the mixing kettle 32, the controller 16 can activate the secondary stirring device 34 to stir the cleaning water within the mixing kettle 32 to enhance the cleaning effect. The controller 16 can pre-set a cleaning time, and upon reaching the cleaning time, the cleaning of the mixing kettle 32 can be stopped. Specifically, the cleaning valve 665 is closed and the water supply pump 61 is stopped, thereby stopping the supply of cleaning water to the mixing kettle 32. After the cleaning of the mixing kettle 32 is completed, the cleaning water can be discharged from the mixing kettle 32 through the output port of the mixing kettle 32.

[0126] According to some embodiments of the present application, the primary dilution process may include: delivering the agent to the dilution tank; injecting dilution water into the dilution tank to form a primary dilution agent with a predetermined dilution amount; and delivering the formed primary dilution agent to the mixing tank.

[0127] In some embodiments, delivering the agent to the dilution tank may include: delivering a predetermined amount of the agent from the dosing cartridge to the dilution tank using a metering pump; and delivering flushing water from the flushing cartridge to the dilution tank using a metering pump, the amount of flushing water being included in the predetermined dilution amount.

[0128] In some embodiments, injecting dilution water into the dilution tank may include: injecting dilution water into the dilution tank through a water supply module, so that the primary dilution agent formed in the dilution tank reaches the predetermined dilution amount.

[0129] In some embodiments, the primary dilution process may further include: using a stirring device to stir the primary dilution agent formed in the dilution kettle.

[0130] In some embodiments, the primary dilution process may further include: before delivering the agent to the dilution tank, injecting a predetermined buffer amount of water into the dilution tank through a water supply module, wherein the predetermined buffer amount is included in the predetermined dilution amount.

[0131] In some embodiments, the primary dilution process may further include: after the formed primary dilution reagent is transported to the mixing kettle, washing water is injected into the dilution kettle through the water supply module to clean the dilution kettle, and after the cleaning of the dilution kettle is completed, the washing water is transported to the mixing kettle.

[0132] In some embodiments, injecting wash water into the dilution tank via the water supply module includes: delivering the wash water via the water supply module to a cleaning device disposed within the dilution tank, thereby cleaning the dilution tank via the cleaning device. In some embodiments, the amount of wash water can be controlled by the time the water supply module injects water. In some embodiments, cleaning the dilution tank includes: stirring the wash water in the dilution tank using a stirring device.

[0133] Specifically, if Figure 9 As shown, the specific steps of the primary dilution process are shown. The specific steps of the primary dilution process are described below with reference to a specific embodiment. Those skilled in the art will appreciate that some steps in the specific embodiment may be optional and may be modified, changed, or combined to form new technical solutions without departing from the spirit and scope of the present application.

[0134] like Figure 9 As shown, at step S310, a predetermined buffer volume of water is injected into the dilution tank 22. The controller 16 opens the dilution valve 643 on the dilution and replenishment water pipeline 642 and starts the water supply pump 61. The water supply pump 61 pumps the buffer water through the main pipeline 62 of the water supply module 60 and the dilution and replenishment water pipeline 642 into the dilution tank 22. At this time, the weight change of the dilution tank 22 is monitored by the weight sensor 72 to control the amount of buffer water injected into the dilution tank 22. When the predetermined buffer volume is reached, the controller 16 closes the dilution valve 643 and stops the water supply pump 61, ensuring that the predetermined buffer volume of water is contained in the dilution tank 22. Adding buffer water to the dilution tank 22 before adding the reagent prevents the reagent from directly contacting the inner wall of the dilution tank 22 and causing damage to the dilution tank 22.

[0135] At step S320, the reagents are delivered to the dilution tank 22 via the dosing module 40. The controller 16 first determines the order in which the reagents should be added, opens the first valve 424 corresponding to the dosing cartridge 42 containing the first reagent, and activates the metering pump 44. This pumps the first reagent from the dosing cartridge 42 through the first tube 422, the connector 48, the metering pump 44, and the third tube 442 into the dilution tank 22. The metering pump 44 controls the amount of reagent pumped. When the pumped amount reaches a predetermined amount, the controller 16 closes the first valve 424 and stops the metering pump 44. Subsequently, the controller 16 opens the second valve 464 and activates the metering pump 44, pumping flushing water from the flushing cartridge 46 through the second tube 462, the connector 48, the metering pump 44, and the third tube 442 into the dilution tank 22. During this process, the flushing water flushes any residual reagent in the metering pump 44 and the third tube 442 into the dilution tank 22.

[0136] At step S330, dilution water is injected into the dilution tank 22 via the water supply module 60 to cause primary dilution of the reagent in the dilution tank 22, forming a primary diluted reagent. The controller 16 opens the dilution valve 643 on the dilution and replenishment water pipe 642 and activates the water supply pump 61. The water supply pump 61 pumps the dilution water through the main pipe 62 of the water supply module 60 and the dilution and replenishment water pipe 642 into the dilution tank 22. At this point, the weight of the dilution tank 22 is monitored by the weight sensor 72 to control the amount of dilution water injected into the dilution tank 22. When the predetermined dilution amount is reached, the controller 16 closes the dilution valve 643 and stops the water supply pump 61, ensuring that the predetermined amount of primary diluted reagent is contained in the dilution tank 22.

[0137] At step S340, the primary dilution agent contained in the dilution tank 22 is stirred by the primary stirring device 24. The controller 16 activates the primary stirring device 24, specifically, activates the motor 242 to cause the stirring element 248 to stir the primary dilution agent contained in the dilution tank 22 to obtain a uniform primary dilution agent. The controller 16 can set a stirring time so that the stirring of the primary stirring device 24 stops when the stirring time expires.

[0138] At step S350, the formed primary diluent is delivered to the mixing tank 32. The controller 16 opens the delivery valve 231, so that the primary diluent in the dilution tank 22 is delivered to the mixing tank 32 through the connecting pipe 23. After the delivery is completed, the controller closes the delivery valve 231.

[0139] At step S360, the dilution tank 22 is cleaned via the water supply module 60, and the cleaning water is delivered to the mixing tank 32. The controller 16 opens the cleaning valve 645 on the dilution cleaning pipe 644 and starts the water supply pump 61. The water supply pump 61 pumps the cleaning water through the main pipe 62 and the dilution cleaning pipe 644 into the dilution tank 22 to clean the dilution tank 22. In some embodiments, the cleaning water can be delivered via the dilution cleaning pipe 644 and through the cleaning port 232 to the primary cleaning device 234, which then uses the cleaning water to clean the dilution tank 22. Furthermore, while cleaning the dilution tank 22, the controller 16 can activate the primary stirring device 24 to stir the cleaning water in the dilution tank 22 to enhance the cleaning effect. The controller 16 can pre-set a cleaning time, and upon reaching the cleaning time, the cleaning of the dilution tank 22 can be stopped. Specifically, the cleaning valve 645 is closed and the water supply pump 61 is stopped, thereby ceasing the supply of cleaning water to the dilution tank 22. After the dilution tank 22 is cleaned, the controller 16 opens the delivery valve 231 so that the cleaning water in the dilution tank 22 is delivered to the mixing tank 32 through the connecting pipe 23. After the delivery is completed, the controller closes the delivery valve 231.

[0140] The above steps S310 to S360 are repeatedly performed for each medicine until the primary diluted medicine formed by all medicines is delivered to the mixing kettle 32.

[0141] According to some embodiments of the present application, the secondary dilution and mixing process may include: after receiving the corresponding primary dilution reagents of all reagents from the dilution kettle, injecting mixing water into the mixing kettle, and performing secondary dilution and mixing on all the primary dilution reagents to form a secondary mixed reagent with a predetermined mixing amount.

[0142] In some embodiments, injecting the mixing water into the mixing kettle may include: injecting the mixing water into the mixing kettle through a water supply module, so that the secondary mixed reagent formed in the mixing kettle reaches the predetermined mixing amount.

[0143] In some embodiments, the secondary dilution and mixing process may further include: before delivering the primary dilution agent to the mixing kettle, injecting a predetermined buffer amount of water into the mixing kettle through a water supply module, wherein the predetermined buffer amount is included in the predetermined mixing amount.

[0144] In some embodiments, the secondary dilution and mixing process may further include: using a stirring device to stir the secondary mixed reagent formed in the mixing kettle.

[0145] Specifically, if Figure 10 The specific steps of the secondary dilution and mixing process are shown in FIG. The specific steps of the secondary dilution and mixing process are described below with reference to a specific embodiment. Those skilled in the art will appreciate that some steps in the specific embodiment may be optional and may be modified, changed, or combined to form new technical solutions without departing from the spirit and scope of the present application.

[0146] like Figure 10 As shown, at step S510, a predetermined buffer volume of water is injected into the mixing kettle 32. The controller 16 opens the mixing valve 663 provided on the mixing and replenishing water pipe 662 and starts the water supply pump 61. The water supply pump 61 pumps the buffer water through the main pipe 62 of the water supply module 60 and the mixing and replenishing water pipe 662 into the mixing kettle 32. At this time, the weight change of the mixing kettle 32 is monitored by the weight sensor 74 to control the amount of buffer water injected into the mixing kettle 32. When the predetermined buffer volume is reached, the controller 16 closes the mixing valve 663 and stops the water supply pump 61, ensuring that the predetermined buffer volume of water is contained in the mixing kettle 32. Adding buffer water to the mixing kettle 32 before delivering the primary dilution agent to the mixing kettle 32 prevents the agent from directly contacting the inner wall of the mixing kettle 32 and causing damage to the mixing kettle 32.

[0147] At step S530 , all the primary dilution reagents from the dilution tank 22 are received in the mixing tank 32 . That is, as described above, steps S310 to S360 are repeatedly performed for each reagent until the primary dilution reagents formed by all the reagents are delivered to the mixing tank 32 .

[0148] At step S550, mixing water is injected into the mixing kettle 32 via the water supply module 60, causing the primary diluent to undergo secondary dilution and mixing within the mixing kettle 32, forming a secondary mixed agent. The controller 16 opens the mixing valve 663 on the mixing and replenishing water pipe 662 and activates the water supply pump 61. The water supply pump 61 pumps the mixed water through the main pipe 62 of the water supply module 60 and the mixing and replenishing water pipe 662 into the mixing kettle 32. At this point, the weight of the mixing kettle 32 is monitored by the weight sensor 74 to control the amount of mixing water injected into the mixing kettle 32. When the predetermined mixed amount is reached, the controller 16 closes the mixing valve 663 and stops the water supply pump 61, ensuring that the predetermined mixed amount of secondary mixed agent is contained within the dilution kettle 22.

[0149] At step S570, the secondary mixed agent contained in the mixing kettle 32 is stirred by the secondary stirring device 34. The controller 16 activates the secondary stirring device 34, specifically, activates the motor 342 to cause the stirring element 348 to stir the secondary mixed agent contained in the mixing kettle 32 to obtain a uniform secondary mixed agent. The controller 16 can set a stirring time so that the stirring of the secondary stirring device 34 stops when the stirring time expires.

[0150] The technical solution of this application has achieved significant technical benefits. For example, during the plant protection process, the pesticide can be automatically diluted and mixed according to the set concentration and automatically cleaned, saving time and effort, reducing manual intervention, and avoiding the possibility of pesticides causing harm to the human body during the work process. Compared with manual stirring, the stirring is more uniform, the mixing quality is better, the efficiency is higher, and the pollution is reduced.

[0151] This application is designed with an automatic dosing device that automatically measures the required amount of medicine. Compared with manual dosing, it is more accurate and avoids direct human contact with the medicine, reducing the possibility of harm from high-concentration medicines. Multiple medicines are continuously dispensed and accurately delivered to the primary dilution kettle in the order in which they are mixed, which is more efficient and more scientific.

[0152] The design of this application is based on the principle of secondary dilution of drug mixing. The first stage is the primary dilution module, which is used to dilute the drug to a lower concentration to avoid the difficulty of direct dilution and mixing of the drug and the difficulty in ensuring mixing uniformity; the second stage evenly mixes two or more primary diluted drugs to the required concentration to achieve the purpose of scientific mixing.

[0153] The present application is designed with a weight monitoring device, which mainly controls the dilution concentration by monitoring the weight changes of the water and reagents injected into the dilution kettle and the mixing kettle through a weight sensor.

[0154] Although exemplary embodiments of the present application have been described, it will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present application without departing substantially from the spirit and scope of the present application. Therefore, all such changes and modifications are intended to be within the scope of protection of the present application as defined by the appended claims. The present application is defined by the appended claims, and equivalents of these claims are intended to be included therein.
