Description

Technical Field

[0001] This invention relates to the field of aqueous pesticide preparation technology, specifically to an automatic aqueous pesticide preparation system. Background Technology

[0002] In modern agricultural pest and disease control, aqueous pesticides, with their advantages of good solubility, uniform diffusion, low irritation to crops, and compatibility with various plant protection spraying equipment, have become one of the most widely used pesticide formulations in field planting, fruit and vegetable cultivation, and garden maintenance. Pesticide preparation is a core pre-treatment step in plant protection spraying; the accuracy of preparation, the uniformity of mixing, and the level of automation directly determine the effectiveness of pest and disease control, while also affecting pesticide utilization, the farmland ecological environment, and the personal safety of operators. However, current preparation equipment has some shortcomings, as follows:

[0003] When preparing pesticide solutions, pipeline contamination is a prominent issue. When different types of aqueous pesticides are mixed alternately, pesticide residues can easily remain inside the pipelines. Incomplete cleaning can easily lead to pesticide mixing reactions and efficacy conflicts, which not only affect the accuracy of pesticide preparation but also shorten the service life of the equipment. Furthermore, pipeline cleaning requires interrupting the pesticide preparation process, affecting the efficiency of the equipment. Therefore, there is an urgent need for a pesticide preparation device that can automatically clean pesticide pipelines. Summary of the Invention

The concentrate is then directed to the mixing device via the clean water tank. After mixing, the concentrate is directed to the mixing chamber, and the clean water from the clean water tank continues to be directed to the mixing device to clean the inner cavity of the mixing device, ensuring that all the pesticide concentrate is carried to the mixing chamber and completing the cleaning of the mixing device. A stirring device is movably installed in the mixing chamber to agitate the pesticide mixture entering the mixing chamber, so that the pesticide concentrate and clean water are fully mixed. A valve is fixedly installed at the bottom of the mixing chamber and installed on the other side.

[0006] Preferably, the dispensing device includes a swing cylinder mounted on a support frame, with shaft tubes fixedly mounted at both ends of the swing cylinder. Multiple metering valves I are fixedly mounted on the swing cylinder, and connecting sleeves for connecting pesticide bottles are fixedly mounted on each metering valve I, allowing the bottle openings to be connected to the connecting sleeves. Metering valves II are fixedly mounted on the shaft tubes at both ends of the swing cylinder. Metering valves I precisely measure the pesticide concentrate entering the swing cylinder, ensuring accurate pesticide mixing ratios. Metering valves II measure the amount of water, achieving precise on-demand pesticide dispensing.

[0007] Preferably, the inside of the swing cylinder is provided with a rubber bladder, and the two ends of the rubber bladder are respectively fixedly connected to the metering valve II, and the middle part is connected to the metering valve I through a hose.

[0008] Preferably, the steering device is semi-circular and includes a semi-circular support ring with a limiting hole. An arc-shaped rack is fixedly mounted on the semi-circular support ring. The steering device is equipped with a clamping device facing the connecting sleeve. The clamping device includes a connecting plate mounted on the semi-circular support ring. A clamping assembly movably connected to the limiting hole is mounted on the connecting plate. A support spring is movably mounted on the clamping assembly for supporting the connection plate and the clamping assembly, which can press the medicine bottle against the dispensing device. A drive motor is fixedly mounted on the connecting plate, and a drive gear is fixedly mounted on the output shaft of the drive motor. The drive gear meshes with the arc-shaped rack.

[0014] The present invention has the following beneficial effects:

[0015] The pesticide mixing device allows for initial mixing of the pesticide solution. Subsequently, clean water further dilutes the mixture within the device. Once the device's interior is full, additional water carries the pesticide solution into the mixing tank, where dilution continues. After all the pesticide solution has been discharged, a continuous stream of clean water cleans the device's interior. This dilution process not only cleans the device, ensuring no excess pesticide residue remains for subsequent applications, but also guarantees the correct dosage of pesticide enters the mixing tank, ensuring accurate pesticide application and preventing future pesticide contamination. It also reduces the amount of water used in the mixing pipelines, saving on cleaning costs and preventing pesticide-contaminated cleaning water from overflowing and polluting the environment.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figure 1-8 An automatic pesticide dispensing system for aqueous solutions includes a control panel, a clean water tank 1 containing clean water, and a dispensing tank 2. It also includes a steering device 3, which is fixedly mounted on the clean water tank 1. A support frame 4 is fixedly mounted on the steering device 3, and a dispensing device 5 is movably mounted on the support frame 4. A pesticide bottle 7 is mounted on the dispensing device 5. The two ends of the dispensing device 5 are connected to the clean water tank 1 and the dispensing tank 2 respectively via conduits. The pesticide in the pesticide bottle 7 is introduced into the dispensing device 5 in a certain proportion for preliminary mixing to obtain a pesticide concentrate of a certain concentration. Subsequently, the clean water tank 1 is dewatered. The clean water in the water tank 1 is directed to the pesticide mixing device 5. After mixing with the pesticide mixing device 5, the water is directed to the pesticide mixing tank 2. The clean water in the water tank 1 is continuously directed to the pesticide mixing device 5 to clean the inner cavity of the pesticide mixing device 5, ensuring that all the pesticide concentrate is carried to the pesticide mixing tank 2 and completing the cleaning of the pesticide mixing device 5. The stirring device 9 is movably installed in the pesticide mixing tank 2, which can stir the pesticide mixture entering the pesticide mixing tank 2, so that the pesticide concentrate and clean water are fully mixed. A 14 is fixedly installed on one side of the bottom of the pesticide mixing tank 2, and an air valve is installed on the other side.

[0027] First, connect the pesticide bottle 7 (for preparing pesticides) to the mixing device 5. Under the influence of gravity, the concentrate is mixed into the mixing device 5 in a certain proportion for initial mixing. Then, clean water from the clean water tank 1 is also supplied to the mixing device 5, allowing the clean water to initially dilute the mixed concentrate in the mixing device 5. Once the entire internal space of the mixing device 5 is filled, subsequent water intake will carry the pesticide solution and be supplied to the mixing tank 2. During the supply process, continuous dilution occurs until all the pesticide solution is discharged from the mixing device 5. Afterwards, the continuously supplied clean water cleans the inner cavity of the pesticide mixing device 5. During the dilution of the pesticide solution, the flowing clean water not only cleans the pesticide mixing device 5, ensuring that there is no excess pesticide residue in the device 5 for the next pesticide mixing, but also ensures that the required amount of pesticide solution enters the pesticide mixing tank 2 for pesticide application, thereby ensuring the accuracy of pesticide mixing and preventing the pesticide solution from mixing and affecting its effectiveness. It also reduces the additional water used for the pesticide mixing pipeline, saves cleaning costs, and prevents pesticide-containing cleaning water from overflowing and polluting the environment.

[0028] The pesticide dispensing device 5 includes a swing cylinder 51 mounted on a support frame 4, with shaft tubes fixedly mounted at both ends of the swing cylinder 51. Multiple metering valves I 52 are fixedly mounted on the swing cylinder 51, and connecting sleeves 53 for connecting pesticide bottles 7 are fixedly mounted on the metering valves I 52. The bottle mouth of the pesticide bottle 7 can be connected to the connecting sleeve 53. Metering valves II 54 are fixedly mounted on the shaft tubes at both ends of the swing cylinder 51, respectively. The pesticide concentrate is accurately metered into the swing cylinder 51 through the metering valves I 52 to ensure accurate pesticide ratio. The amount of clean water is metered through the metering valves II 54 to achieve accurate on-demand pesticide dispensing.

[0029] The inside of the swing cylinder 51 is equipped with a rubber bladder 55, and both ends of the rubber bladder 55 are fixedly connected to the metering valve II 54, while the middle part is connected to the metering valve I 52 through a hose. By setting the rubber bladder 55, the rubber bladder 55 serves as a container for dispensing medicine inside the swing cylinder 51. The medicine and water are mixed in the rubber bladder 55. Furthermore, since the rubber bladder 55 is relatively soft, at the end of the dilution, some of the water remaining in the rubber bladder 55 is then drawn out by the negative pressure created by the stirring device 9 in the dispensing tank 2 through the metering valve II 54. Under the action of negative pressure, the rubber bladder 55 contracts, allowing the remaining water inside to be squeezed into the dispensing tank 2, so that a fixed amount of water enters the dispensing tank 2, thereby accurately controlling the concentration of the medicine.

[0030] The steering device 3 is semi-circular and includes a semi-circular support ring 31 with a limit hole 32. An arc-shaped rack 33 is fixedly mounted on the semi-circular support ring 31. A clamping device 6 is mounted on the steering device 3, directly opposite the connecting sleeve 53. The clamping device 6 includes a connecting plate 61 mounted on the semi-circular support ring 31. A clamping assembly 62, movably connected to the limit hole 32, is movably mounted on the connecting plate 61. A support spring 63 is movably mounted on the clamping assembly 62 for support between the connecting plate 61 and the clamping assembly 62, pressing the medicine bottle 7 against the dispensing device 5. A drive motor 8 is fixedly mounted on the connecting plate 61, and a drive gear is fixedly mounted on the output shaft of the drive motor 8. The drive gear meshes with the arc-shaped rack 33. Through the cooperation of the steering device 3 and the clamping device 6, the clamping device 6 first... The holding device 6 is positioned below the dispensing device 5. The bottle 7 is then positioned with its opening facing upwards and engaged with the metering valve I 52. Simultaneously, the clamping assembly 62, supported by the support spring 63, clamps the bottom of the bottle 7. The drive motor 8 then rotates the drive gear, which, in conjunction with the arc-shaped rack 33, rotates the holding device 6, the bottle 7, and the dispensing device 5 180 degrees. This causes the liquid in the bottle 7 to move towards the metering valve I 52 under gravity, allowing it to pass through the valve and enter the rubber bladder 55. During this process, the bottle 7 can be resealed shortly after the cap is opened, preventing prolonged exposure of the liquid to the outside and avoiding exposure of volatile liquids to the air, which could affect the dispensing personnel. This also facilitates the dispensing of the liquid.

[0031] The shaft tubes at both ends of the swing cylinder 51 are eccentrically set. When the dispensing device 5 rotates 180 degrees, the central axis of the swing cylinder 51 is located below the shaft tube. Therefore, the medicine first converges in the inner cavity of the swing cylinder 51. Then, through the cooperation of the drive motor 8 and the arc-shaped rack 33, the swing cylinder 51 can be driven to reciprocate, shaking the incoming medicine so that the various medicines can be mixed evenly. The eccentricity strengthens the shaking amplitude of the swing cylinder 51, thereby enhancing the mixing effect. When the medicine needs to be discharged, the swing cylinder 51 returns to its original position. At this time, the central axis of the swing cylinder 51 is above the shaft tube, thus facilitating the flow of medicine out of the swing cylinder 51.

[0032] A limit frame 11 is fixedly installed on the medicine preparation tank 2. A lifting hydraulic rod 12 is fixedly installed on the limit frame 11. The lifting hydraulic rod 12 is set vertically downward, and a rotary motor 13 is fixedly installed on its extended end. A limit ring is set on the rotary motor 13 and is movably connected to the limit frame 11. The output shaft of the rotary motor 13 is fixedly connected to the top of the stirring device 9. The rotary motor 13 can drive the stirring device 9 to rotate, thereby agitating the medicine liquid entering the medicine preparation tank 2 and enhancing the mixing effect of the medicine liquid. At the same time, the lifting hydraulic rod 12 drives the stirring device 9 to rise and fall, so that the medicine liquid can be stirred at all heights, ensuring that the medicine liquid is fully mixed and diluted, and avoiding the separation and sedimentation of the medicine liquid.

[0033] The stirring device 9 includes a shaft 91 and a shaft cylinder 92. The shaft 91 has a vertical groove and is connected to the shaft cylinder 92 via a slot. A lower plate 93 is fixedly mounted at the bottom end of the shaft 91, and an upper plate 94 is fixedly mounted at the bottom end of the shaft cylinder 92. Slots are provided on both the lower plate 93 and the upper plate 94. Guide holes I 95 are evenly distributed on the lower plate 93 within its slots, and guide holes II 96 are distributed on the upper plate 94 within its slots. The diameter of guide hole I 95 is twice the diameter of guide hole II 96. The rotating motor 13 drives the shaft 91 to rotate, which in turn drives the shaft cylinder 92 to rotate synchronously, thereby also driving the lower plate 93 and the upper plate 94. The grooves and protrusions create agitation of the medicinal liquid, ensuring thorough mixing. As the hydraulic rod 12 moves the stirring device 9 up and down, the medicinal liquid passes through guide holes I 95 and II 96. During descent, the liquid passes through guide hole I 95, then through the gap between the lower plate 93 and the upper plate 94, and finally through guide hole II 96. During ascent, the process is reversed. The different diameters of guide holes I 95 and II 96 allow the liquid to pass through filter holes of varying diameters, causing the liquid to split and merge within the filter holes, thus enhancing the mixing effect.

[0034] The lower plate 93 and the upper plate 94 have the same shape and can be installed together through a slot to form a cylinder. The top of the shaft cylinder 92 is fixedly installed with a piston rod 10, and the extended end of the piston rod 10 is fixedly connected to the top of the shaft rod 91. Through the piston rod 10, the shaft cylinder 92 is driven to rise and fall on the shaft rod 91, thereby causing the lower plate 93 and the support frame 4 to combine and separate. After combination, a piston-type cylinder is formed. Then, under the drive of the lifting hydraulic rod 12, a piston movement is formed in the medicine tank 2. In the initial stage, a negative pressure can be formed inside the medicine tank 2, thereby sucking the medicine liquid inside the medicine preparation device 5 and the clean water inside the clean water tank 1.

[0035] A stirring blade 97 is fixedly installed on the upper surface of the upper plate 94, which enhances the stirring effect inside the dosing tank 2.

[0036] The working principle is as follows: First, the clamping device 6 is positioned below the dispensing device 5. Then, the mouth of the medicine bottle 7 is turned upwards and engaged with the metering valve I 52. Simultaneously, the clamping assembly 62, under the action of the support spring 63, supports the bottom of the medicine bottle 7 and clamps it. Then, the drive motor 8 drives the drive gear to rotate, and with the cooperation of the arc-shaped rack 33, it drives the clamping device 6, the medicine bottle 7, and the dispensing device 5 to rotate 180 degrees, thereby causing the medicine in the medicine bottle 7 to be dispensing under the influence of gravity. Under the action of force, it approaches the metering valve I 52, and then, under the action of gravity, it passes through the metering valve I 52 and enters the rubber bladder 55. Subsequently, the drive motor 8 drives the drive gear to move on the arc rack 33, and then drives the dispensing device 5 to swing 0-60 degrees through the clamping device 6, carefully shaking the liquid medicine inside the rubber bladder 55 to achieve preliminary mixing. Then, the lifting hydraulic rod 12 drives the stirring device 9 to rise and fall in the dispensing tank 2, so that the lower plate 93 and the upper plate 94 are under the action of the piston rod 10. The lower part is in a combined state, thus achieving a piston effect, drawing and transferring the liquid medicine in the dispensing device 5, and drawing water from the clear water tank 1 to dilute the liquid medicine. After the liquid medicine and clear water are drawn into the dispensing tank 2, the rotating motor 13 drives the shaft 91 to rotate, which in turn drives the shaft cylinder 92 to rotate synchronously, and the lower plate 93 and upper plate 94 are also driven. Due to the slots and the protrusions formed, the liquid medicine is stirred, and the liquid medicine is fully stirred. The lifting hydraulic rod 12 also drives... During the lifting and lowering process of the stirring device 9, the liquid medicine passes through the guide hole I 95 and the guide hole II 96. The lifting hydraulic rod 12 drives the stirring device 9 to lift and lower. When it descends, the liquid medicine passes through the guide hole I 95, then through the gap between the lower plate 93 and the upper plate 94, and then through the guide hole II 96. When it rises, the opposite is true. By utilizing the different diameters of the guide hole I 95 and the guide hole II 96, the liquid medicine passes through filter holes of different diameters, causing the liquid medicine to split and merge in the process, thus enhancing the stirring effect.
