Description

Technical Field

[0001] This utility model relates to the field of microbial fertilizer production technology, and in particular to a sampling device for microbial fertilizer production. Background Technology

[0002] The core technology of microbial fertilizer production lies in the screening and large-scale cultivation of highly efficient functional strains. Producers first isolate natural strains with excellent abilities such as nitrogen fixation, phosphorus solubilization, and growth promotion from the natural environment. Then, they optimize and breed them using modern biotechnology to obtain vigorous production strains. On this basis, advanced fermentation engineering equipment is used to precisely control parameters such as temperature, pH, and aeration to achieve large-scale and efficient propagation of microbial agents. Currently, in the process of microbial fertilizer production, it is necessary to regularly sample and observe the growth of microbial fertilizer. In the process of sampling and observation, special attention needs to be paid to achieving aseptic operation. After each sampling, the sampler needs to be manually cleaned to facilitate the next use. However, manual cleaning is quite troublesome and wastes a lot of time each time. Utility Model Content

Detailed Implementation

[0012] Reference Figures 1-5 A sampling device for microbial fertilizer production, comprising: Production tank 1 is a device specifically designed for the production of microbial fertilizers. It features functions such as heat preservation and stirring, which is existing technology and will not be elaborated upon further. Three support columns 2 are fixedly connected to the lower side of production tank 1. An output pipe 3 is also fixedly installed on the lower side of production tank 1, allowing the produced fertilizer to be discharged. A sampling structure is installed on production tank 1, including a sampling tube 4 fixedly connected to the side wall of production tank 1. A partition plate 5 is fixedly connected to the inner side of sampling tube 4, dividing it into two parts. A hydraulic device 6 is fixedly installed inside sampling tube 4, consisting of a hydraulic pump and a hydraulic rod. The hydraulic rod extends by inputting hydraulic oil. This is also existing technology and will not be elaborated upon further. A sampler 7 is fixedly connected to the output end of the hydraulic device 6. The sampler 7 is a through-hole object with a conical front end. The hydraulic device 6 enables the sampler 7 to move into the production tank 1. The conical shape at the front end reduces resistance. After entering the production tank 1, the sampler 7 pushes aside the microbial fertilizer. Once the sampler 7 is fully inside the production tank 1, the microbial fertilizer falls due to gravity, reaching the through-hole of the sampler 7. At this point, the hydraulic device 6 causes the sampler 7 to move back, bringing back the portion located in the middle of the sampler 7. After the sampler 7 moves into the sampling tube 4, because the middle part of the sampler 7 fits tightly with the sampling tube 4, the sampler 7 can also act as a stopper, preventing the microbial fertilizer in the production tank 1 from flowing into the sampling tube 4, thus completing the sampling work. Two baffles 19 are slidably connected to the side wall of the sampling tube 4, and a rack 20 is fixedly connected to the side wall of each baffle 19. A spur gear 21 is rotatably installed on the lower side of the sampling tube 4, and both racks 20 mesh with the spur gear 21. A pin 23 is fixedly connected to the side wall of one baffle 19, and a groove is opened on the side wall of the other baffle 19 for the pin. Corresponding to the groove, pin 23 can be inserted into the groove, thereby improving the closing effect of the two baffles 19. One of the baffles 19 has a pull ring 22 fixedly connected to its side wall. By pulling the pull ring 22, the baffle 19 can be moved. When the baffle 19 moves, it can drive the spur gear 21 to rotate through the rack 20, thereby causing the spur gear 21 to drive the other rack 20 to move, thus moving the other baffle 19 as well. This allows the fertilizer sample carried out to fall from the sampling tube 4 into the prepared sampling dish. During the sampling process, the two baffles 19 do not open. After completion, the sampler is opened, and at this time the sampler 7 is already in the sampling tube 4. Because the middle section of the sampler 7 is completely in contact with the sampling tube 4, it can act as a stopper, thus preventing air from entering the production tank 1. Air itself does not affect the growth of microorganisms; what affects them are the microbial strains in the air. After the air enters the sampling tube 4, the microbial strains in the air will be killed by the bactericidal liquid sprayed by the rotating spray structure after sampling is completed, thus preventing the microbial strains in the air from causing any impact. The sampling tube 4 is equipped with a rotating spray structure and a cleaning structure.

[0013] The rotary spraying structure includes a water tank 8 fixedly installed on the upper side of the sampling tube 4. Multiple spray pipes 9 are rotatably connected to the lower side of the water tank 8. The multiple spray pipes 9 rotatably pass through the sampling tube 4. The rotatable passage here uses a sealed bearing mechanical component to ensure good sealing. High-pressure nozzles 10 are fixedly connected to the lower ends of the multiple spray pipes 9. Adjacent spray pipes 9 are connected by a pulley assembly 11. The pulley assembly 11 consists of two rotating wheels and a belt, which has the function of power transmission. A control motor 12 is fixedly installed inside the sampling tube 4. A rotating shaft 13 is rotatably connected to the side wall of the sampling tube 4. A bevel gear 14 is fixedly sleeved on the outer side of the output end of the rotating shaft 13 and the two bevel gears 14 mesh with each other. The rotating shaft 13 is connected to the adjacent spray pipes 9 by a pulley assembly 2 15. The pulley assembly 2 15 also consists of two rotating wheels and a belt.

[0014] The cleaning structure includes a rotating plate 16 fixedly installed at the output end of the control motor 12. The rotating plate 16 is rotatably connected to the partition plate 5. Two cleaning rods 17 are fixedly connected to the side wall of the rotating plate 16. Multiple rubber soft brushes 18 are fixedly connected to the side wall of each of the two cleaning rods 17.

[0015] In this invention, firstly, when it is necessary to sample and test the microbial fertilizer in the production tank 1, the hydraulic device 6 moves the sampler 7 into the production tank 1. The cone at the front end reduces resistance, and due to gravity, some fertilizer falls into the middle of the sampler 7. The hydraulic device 6 drives the sampler 7 back, bringing some fertilizer sample back to the sampling tube 4. Pulling the pull ring 22 moves one of the baffles 19. The movement of the baffle 19 drives the spur gear 21 to rotate via the rack 20. The rotation of the spur gear 21 drives the other baffle 19 to move via the other rack 20, thus bringing the sample into the sampling tube 4. The sample fertilizer falls into the sampling dish. At this time, the high-pressure nozzle 10 sprays a sterilizing liquid through the water tank 8. Adhering to the principle of "non-toxic, easily degradable, and residue-free" for the functional strains of microbial fertilizers, a food-grade 3% hydrogen peroxide solution or a 50-100 ppm hypochlorous acid solution is selected. Food-grade hydrogen peroxide is a commonly used bactericide in agriculture and has no inhibitory effect on the core strains of microbial fertilizers such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria. Therefore, spraying it will not affect the core strains in the production tank. Furthermore, it can be completely degraded into water and oxygen within 12-24 hours at room temperature, leaving no chemical residue and thus will not affect the sampling. By starting the control motor 12, the output end can drive the rotating shaft 13 to rotate through two bevel gears 14. The rotating shaft 13 drives the adjacent spray pipes 9 to rotate through the second belt pulley assembly 15. The adjacent spray pipes 9 are mutually driven through the first belt pulley assembly 11, so that multiple spray pipes 9 can drive the high-pressure nozzle 10 to rotate, thereby making the spraying range wider. In addition, the output end of the control motor 12 can also drive the two cleaning rods 17 to rotate through the rotating plate 16. The rotation of the two cleaning rods 17 enables the rubber soft brush 18 to clean the inside of the sampling tube 4 and the sampler 7. Combined with the rotation and spraying of the high-pressure nozzle 10, the cleaning effect is better, ensuring a sterile operating environment.
