[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-6 This utility model provides a technical solution:
[0034] A raw material mixing device for pesticide production includes a mixing chamber 1. An inlet pipe 2 is disposed above the mixing chamber 1, and a rotary joint 3 is fixedly connected to the bottom end of the inlet pipe 2. A rotating pipe 4 is rotatably disposed in the middle of the mixing chamber 1, and the top end of the rotating pipe 4 is fixedly connected to the rotating end of the rotary joint 3. Evenly distributed and symmetrically arranged stirring pipes 5 are fixedly installed on the side of the rotating pipe 4. A spring 6 is disposed inside each stirring pipe 5, and a movable pipe 7 is slidably disposed at the end of each stirring pipe 5. The two ends of the spring 6 are fixedly installed to the stirring pipe 5 and the movable pipe 7 respectively. A scraper is fixedly connected to the common end of the movable pipe 7. 8. The scraper 8 is hollow. The scraper 8 has evenly distributed water outlet holes 9 on the side near the inner wall of the mixing tank 1. The top of the mixing tank 1 is provided with a driving component 10 for driving the rotating pipe 4, stirring pipe 5, moving pipe 7 and scraper 8 to rotate. The driving component 10 includes a motor 101 fixedly installed above the mixing tank 1, a gear disk 102 rotatably installed at the bottom of the mixing tank 1, and a gear disk 103 fixedly installed at the end of the rotating pipe 4. The output shaft end of the motor 101 is fixedly installed with the middle of the gear disk 102. The gear disk 102 and the gear disk 103 are meshed and connected for transmission.
[0035] During use, the operator feeds the pesticide raw materials and diluent into the mixing tank 1, and starts the motor 101 on the top of the mixing tank 1 normally. The output shaft of the motor 101 drives the gear disc 102 to rotate. Since the gear disc 102 and the gear disc 2 103 mesh and drive each other, the gear disc 2 103 drives the rotating tube 4 to rotate on the rotary joint 3 and the mixing tank 1. The rotating tube 4 then drives the stirring tube 5, the movable tube 7, and the scraper 8 to rotate synchronously, so as to stir and mix the raw materials in the mixing tank 1.
[0036] During the mixing process, when it is necessary to scrape off the raw materials adhering to the inner wall of the mixing box 1, the power of the motor 101 is increased to drive the rotating tube 4, the movable tube 7, and the scraper 8 to rotate rapidly. Under the action of centrifugal force, the movable tube 7 pulls the spring 6 to slide out along the end of the mixing tube 5. The scraper 8 at the end of the movable tube 7 then adheres to the inner wall of the mixing box 1. The scraper 8 rotates against the inner wall of the mixing box 1 to scrape off the raw materials on the inner wall. After scraping, the mixture is stirred and diluted again.
[0037] By reducing the power of motor 101, the elastic restoring force of spring 6 can pull the movable tube 7 and scraper 8 back to their original positions, and scraper 8 can rotate away from the inner wall of mixing box 1, thus protecting scraper 8 and the inner wall of mixing box 1.
[0038] In addition, when cleaning the inner wall of the mixing tank 1, water enters the hollow scraper 8 through the liquid inlet pipe 2, the rotating pipe 4, the stirring pipe 5, and the movable pipe 7, and is continuously sprayed onto the inner wall of the mixing tank 1 from the water outlet 9. Combined with the scraping action of the rapidly rotating scraper 8, the inner wall of the mixing tank 1 is cleaned.
[0039] This pesticide production raw material mixing equipment integrates stirring and scraping functions. While efficiently stirring to ensure thorough mixing of raw materials, it promptly scrapes off raw materials adhering to the inner wall of the mixing tank 1, effectively avoiding raw material residue loss and improving the raw material mixing rate. At the same time, the scraping function also facilitates cleaning of the inner wall of the mixing tank 1, which not only ensures the mixing quality but also reduces maintenance costs, making it highly practical.
[0040] The size of gear disc 102 is larger than the size of gear disc 2103;
[0041] The size of the first gear disk 102 is larger than that of the second gear disk 103. When the motor 101 drives the first gear disk 102 to rotate, according to the gear transmission principle, the second gear disk 103 will obtain a higher speed, which will enable the rotating tube 4, stirring tube 5, moving tube 7 and scraper 8 fixedly connected to the second gear disk 103 to rotate quickly. During the rapid rotation, the scraper 8 is subjected to a greater centrifugal force, thus adhering more tightly to the inner wall of the mixing box 1, ensuring the scraping effect, and also improving the mixing efficiency.
[0042] Each of the nine water outlets is equipped with a valve 11;
[0043] When water sprays out of the outlet hole 9, the valve 11 at the outlet hole 9 will be opened by the water flow, allowing the water to spray out smoothly. During the normal mixing of raw materials, since there is no outward water pressure, the valve 11 closes by its own elasticity, which can effectively prevent pesticide raw materials from entering the outlet hole 9 and prevent the outlet hole 9 from becoming blocked.
[0044] A base 12 is provided directly below the mixing chamber 1. Evenly distributed support columns 13 are fixedly installed on the base 12. Support plates 14 are fixedly installed at the top of each support column 13. Support plates 14 are fixedly installed on the side of the mixing chamber 1.
[0045] The base 12 is placed on the ground, and the evenly distributed support columns 13 are vertically fixed on the base 12. The support plate 14 at the top of the support column 13 is fixedly connected to the side of the mixing box 1, which stably supports the mixing box 1 and keeps the entire mixing equipment stable during operation.
[0046] A water tank 15 is provided on the outer wall of the mixing tank 1. The water tank 15 is annular and is mounted on the support plate 14. A water pump 16 is fixedly connected to the water tank 15. A vertical pipe 17 is fixedly connected to the outlet of the water pump 16. The top end of the vertical pipe 17 is fixedly connected to the end of the liquid inlet pipe 2.
[0047] Activating the water pump 16 on the water tank 15 can draw water from the water tank 15 and deliver it to the liquid inlet pipe 2 through the vertical pipe 17, thus automatically supplying water to the mixing tank 1.
[0048] A liquid level sensor is installed inside water tank 15;
[0049] The liquid level sensor in the water tank 15 monitors the water level in the water tank 15 in real time. When the water level drops to the preset low level, it prompts the operator to add water to the water tank 15 to avoid water supply interruption during the cleaning process due to water shortage in the water tank 15, so as to ensure that the cleaning work can be completed smoothly and maintain the normal operation of the equipment cleaning function.
[0050] A bottom cover 18 is provided at the bottom of the mixing tank 1, and the bottom cover 18 is threadedly connected to the mixing tank 1.
[0051] The operator can unscrew the bottom cover 18. Since the bottom cover 18 is connected to the mixing tank 1 by threads, it can be removed from the bottom of the mixing tank 1 by rotating the bottom cover 18. The bottom cover 18 can be cleaned separately after removal to remove dirt and residual raw materials. After cleaning, the bottom cover 18 can be reinstalled to the bottom of the mixing tank 1 by threads, which facilitates the daily maintenance and cleaning of the bottom cover 18.
[0052] Working principle:
[0053] During use, the operator feeds the pesticide raw materials and diluent into the mixing tank 1, and starts the motor 101 on the top of the mixing tank 1 normally. The output shaft of the motor 101 drives the gear disc 102 to rotate. Since the gear disc 102 and the gear disc 2 103 mesh and drive each other, the gear disc 2 103 drives the rotating tube 4 to rotate on the rotary joint 3 and the mixing tank 1. The rotating tube 4 then drives the stirring tube 5, the movable tube 7, and the scraper 8 to rotate synchronously, so as to stir and mix the raw materials in the mixing tank 1.
[0054] During the mixing process, when it is necessary to scrape off the raw materials adhering to the inner wall of the mixing box 1, the power of the motor 101 is increased to drive the rotating tube 4, the movable tube 7, and the scraper 8 to rotate rapidly. Under the action of centrifugal force, the movable tube 7 pulls the spring 6 to slide out along the end of the mixing tube 5. The scraper 8 at the end of the movable tube 7 then adheres to the inner wall of the mixing box 1. The scraper 8 rotates against the inner wall of the mixing box 1 to scrape off the raw materials on the inner wall. After scraping, the mixture is stirred and diluted again.
[0055] By reducing the power of motor 101, the elastic restoring force of spring 6 can pull the movable tube 7 and scraper 8 back to their original positions, and scraper 8 can rotate away from the inner wall of mixing box 1, thus protecting scraper 8 and the inner wall of mixing box 1.
[0056] In addition, when cleaning the inner wall of the mixing tank 1, water enters the hollow scraper 8 through the liquid inlet pipe 2, the rotating pipe 4, the stirring pipe 5, and the movable pipe 7, and is continuously sprayed onto the inner wall of the mixing tank 1 from the water outlet 9. Combined with the scraping action of the rapidly rotating scraper 8, the inner wall of the mixing tank 1 is cleaned.
[0057] This pesticide production raw material mixing equipment integrates stirring and scraping functions. While efficiently stirring to ensure thorough mixing of raw materials, it promptly scrapes off raw materials adhering to the inner wall of the mixing tank 1, effectively avoiding raw material residue loss and improving the raw material mixing rate. At the same time, the scraping function also facilitates cleaning of the inner wall of the mixing tank 1, which not only ensures the mixing quality but also reduces maintenance costs, making it highly practical.
[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
