Abstract
Description
Technical Field
[0001] This utility model relates to the field of RNA pesticide technology, and more specifically, to a reaction vessel for preparing RNA pesticides. Background Technology
[0002] RNA pesticides are polynucleotide preparations that interfere with or inhibit the transcription of specific genes in target organisms. They enter the insect body through certain pathways and silence the relevant genes by interfering with the transcription and translation processes of genes related to the growth and development of the insects. This prevents the synthesis of proteins, reduces the insects' environmental adaptability, or causes them to die, ultimately achieving the goal of controlling the insects.
[0003] RNA pesticides have advantages such as high specificity, low resistance development, non-toxicity, no residue, and low research and development costs. They can precisely target specific genes, exhibiting extremely high targeting ability, and are unlikely to develop resistance through gene mutation or off-target effects. Furthermore, the production process of RNA pesticides is clean, non-toxic to humans and other non-target organisms, and rapidly degrades in soil and water, causing no environmental pollution. To ensure product quality, RNA pesticides are typically prepared using reaction vessels.
[0004] Current reaction vessels, such as the one described in Chinese patent application No. 202223565590.1 "A Pesticide Preparation Reaction Vessel," can remove pesticide mixture residues adhering to the end of a temperature sensor probe by using a stretching adjustment operation to allow a cleaning cotton to generate a wiping force. However, in actual use, RNA pesticide mixtures are usually in solution form, and due to their complex molecular structure and biological activity, RNA pesticides typically do not crystallize under normal conditions. Furthermore, due to this characteristic, the mixing force required for RNA pesticides is greater, while the mixing time of the device is long and the reaction efficiency is poor. Therefore, improvements and optimizations are needed. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, this invention provides a reaction vessel for preparing RNA pesticides, which has the advantage of good mixing effect.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a reaction vessel for preparing RNA pesticides, comprising a vessel body and a support, wherein the vessel body is fixedly installed inside the support, a discharge port is fixedly provided at the bottom of the vessel body, and a vent is fixedly provided on the right side wall of the vessel body;
[0007] A connecting pipe is rotatably installed inside the vessel body. A spray pipe is fixedly installed at the bottom of the connecting pipe. A stirring shaft is fixedly installed at the bottom of the spray pipe. A stirring blade is fixedly installed at the bottom of the stirring shaft.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 7 As shown, this utility model provides a reaction vessel for preparing RNA pesticides, including a vessel body 1 and a support 2. The vessel body 1 is fixedly installed inside the support 2. A discharge port 4 is fixedly provided at the bottom of the vessel body 1, and a vent 3 is fixedly provided on the right side wall of the vessel body 1.
[0028] A connecting pipe 5 is rotatably installed inside the vessel body 1. A spray pipe 6 is fixedly installed at the bottom of the connecting pipe 5. A stirring shaft 7 is fixedly installed at the bottom of the spray pipe 6. A stirring blade 8 is fixedly installed at the bottom of the stirring shaft 7. A scraper 9 is fixedly installed at the bottom of the stirring blade 8.
[0029] A drive wheel 11 is fixedly installed on the outer wall of the connecting pipe 5. A rotating plate 10 is rotatably installed on the outside of the connecting pipe 5. The rotating plate 10 is located below the drive wheel 11. Spiral augers 12 are rotatably installed on both the left and right sides of the rotating plate 10. The top of the spiral auger 12 extends through to the top of the rotating plate 10 and is fixedly installed with a driven wheel 15. A fixed shell 13 is fixedly installed on the inner wall of the top of the vessel body 1. Teeth 14 are provided on the inner wall of the fixed shell 13.
[0030] When preparing RNA pesticides, the staff first prepares the required solution and connects it to the injection valve 20. The injection valve 20 operates, allowing the solution to pass through the injection port 19 and connecting pipe 5, and finally be sprayed out from the nozzle 23 at the spray pipe 6. When adding more solution, the staff starts the motor 21, which drives gear 22 to rotate. Gear 17 further rotates the injection port 19, which in turn drives the connecting pipe 5 to rotate. The spray pipe 6 then rotates, evenly spraying the added solution into the vessel body 1 to ensure thorough mixing. While the spray pipe 6 is rotating and injecting solution, the stirring shaft 7 rotates, causing the stirring blades 8 and... The scraper 9 rotates synchronously to start the stirring operation. When the connecting pipe 5 rotates, the drive wheel 11 follows the rotation of the connecting pipe 5. The drive wheel 11 further drives the driven wheel 15, which meshes with it, to start planetary motion along the gap between the fixed shell 13 and the rotating plate 10. It is worth noting that the rotating plate 10 is rotatably mounted on the outer wall of the connecting pipe 5. When the drive wheel 11 drives the driven wheel 15 to move, the rotating plate 10 will rotate with the displacement of the driven wheel 15, which is responsible for ensuring the stability of the auger 12 and preventing deviation. At this time, the auger 12 will rotate in a circle around the stirring shaft 7. When rotating, it will also rotate on its own axis, further assisting the stirring shaft 7 in the stirring operation.
[0031] The rotation of the connecting pipe 5 drives the stirring shaft 7 to rotate the stirring blades 8 and scraper 9 to begin the stirring operation. At the same time, the rotation of the connecting pipe 5 drives the two sets of driven wheels 15 to rotate, and the auger 12 further begins to perform auxiliary stirring operations. Compared with the traditional device, this device can achieve the stirring function by setting two sets of driven wheels 15, so that when the stirring shaft 7 is performing stirring operations, the auger 12 will rotate around the stirring shaft 7 as the center, thereby improving the mixing efficiency of the solution and the reaction effect.
[0032] The vessel body 1 is fixedly mounted on the top of a fixed base 16. A liquid injection port 19 is rotatably mounted inside the fixed base 16. A gear 17 is fixedly mounted on the outer wall of the liquid injection port 19. The gear 17 is located below the fixed base 16. A motor 21 is fixedly mounted on the top of the fixed base 16. The output shaft of the motor 21 extends through to the bottom of the fixed base 16. The output shaft of the motor 21 is fixedly connected to a gear 22. The gear 22 and the gear 17 mesh with each other.
[0033] The staff connects the solution to the injection valve 20. The injection valve 20 operates, and the solution passes through the injection port 19 and the connecting pipe 5, and is finally sprayed out by the nozzle 23 at the spray pipe 6. When adding solution later, the staff starts the motor 21. The motor 21 drives the gear 22 to rotate, and the gear 17 drives the injection port 19 to rotate. The rotation of the injection port 19 drives the connecting pipe 5 to rotate, and the spray pipe 6 rotates, so that the solution added later is evenly sprayed into the interior of the vessel 1.
[0034] The motor 21 drives the gear 22 to rotate, which in turn drives the injection port 19 to rotate synchronously. When the injection valve 20 is opened to start the injection operation, the injection port 19 will deliver the solution to the spray pipe 6 and spray it into the interior of the vessel body 1 through the rotating nozzle 23. Compared with the traditional device, this device can spray the solution evenly onto the existing solution by rotating when adding the solution, so as to achieve pre-mixing while adding the solution, which improves the mixing effect and shortens the reaction time.
[0035] The driven wheel 15 is located inside the fixed housing 13, and one end of the driven wheel 15 and the fixed housing 13 are meshed with each other through teeth 14, while the other end of the driven wheel 15 is meshed with the drive wheel 11.
[0036] Driven wheel 15 meshes with drive wheel 11 of fixed housing 13, so that auger 12 rotates along the outer wall of drive wheel 11 when drive wheel 11 rotates.
[0037] The outer wall of the spray pipe 6 is provided with a nozzle 23, which is circumferentially arranged on the outer wall of the spray pipe 6 and is interconnected with the spray pipe 6.
[0038] The solution can be sprayed out through the injection port 19 and the connecting pipe 5, and finally sprayed out through the nozzle 23 at the spray pipe 6.
[0039] Among them, the stirring blade 8 is responsible for stirring, the scraper 9 and the conical inner wall of the vessel 1 are in contact with each other, and the scraper 9 is responsible for scraping off the adhered solution.
[0040] The stirring operation is achieved by the stirring blade 8 and the scraper 9, ensuring that the solution is mixed evenly.
[0041] The top of the fixed base 16 is fixedly installed with a sealed chamber 18, and the top of the sealed chamber 18 is fixedly provided with an injection valve 20, and the injection port 19 is rotatably installed inside the sealed chamber 18.
[0042] The sealed chamber 18 and the injection valve 20 are interconnected, so that the injection valve 20 sends the solution into the sealed chamber 18, and the solution is then piped from the sealed chamber 18 to the injection port 19.
[0043] An annular gap is provided between the rotating plate 10 and the fixed shell 13 to allow the spiral auger 12 to rotate.
[0044] When the drive wheel 11 drives the driven wheel 15 to move, the rotating plate 10 will rotate following the displacement of the auger 12, and the moving path of the auger 12 is the annular gap between the rotating plate 10 and the fixed shell 13.
[0045] Working principle and usage process of this utility model:
[0046] When preparing RNA pesticides, the staff first prepares the required solution and connects it to the injection valve 20. The injection valve 20 operates, allowing the solution to pass through the injection port 19 and connecting pipe 5, and finally be sprayed out from the nozzle 23 at the spray pipe 6. When adding more solution, the staff starts the motor 21, which drives gear 22 to rotate. Gear 17 further rotates the injection port 19, which in turn drives the connecting pipe 5 to rotate. The spray pipe 6 then rotates, evenly spraying the added solution into the vessel body 1 to ensure thorough mixing. While the spray pipe 6 is rotating and injecting solution, the stirring shaft 7 rotates, causing the stirring blades 8 and... The scraper 9 rotates synchronously to start the stirring operation. When the connecting pipe 5 rotates, the drive wheel 11 follows the rotation of the connecting pipe 5. The drive wheel 11 further drives the driven wheel 15, which meshes with it, to start planetary motion along the gap between the fixed shell 13 and the rotating plate 10. It is worth noting that the rotating plate 10 is rotatably mounted on the outer wall of the connecting pipe 5. When the drive wheel 11 drives the driven wheel 15 to move, the rotating plate 10 will rotate with the displacement of the driven wheel 15, which is responsible for ensuring the stability of the auger 12 and preventing deviation. At this time, the auger 12 will rotate in a circle around the stirring shaft 7. When rotating, it will also rotate on its own axis, further assisting the stirring shaft 7 in the stirring operation.
