Description

Technical Field

[0001] This utility model relates to the field of microbial inoculation technology, and in particular to a batch rapid inoculation device. Background Technology

[0002] Inoculators are commonly used tools in microbial culture experiments. Generally, bacterial isolation experiments use the streak plate method, which involves using an inoculating needle to dilute the culture medium by streaking it in sections to obtain a large number of independently distributed single cells, which are then cultured and multiplied into single colonies.

[0003] Traditional batch rapid inoculation devices are generally inconvenient to change the position of the inoculation device during use, which can easily affect the inoculation. In addition, the inoculation needles need to be disinfected separately after inoculation. If disinfection is not timely, cross-contamination can occur, affecting the next inoculation. Therefore, this utility model proposes a batch rapid inoculation device. Utility Model Content

[0035] Working Principle: When using this equipment, place the bacterial culture and culture medium into two sets of culture dishes 5 respectively. Place the two sets of culture dishes 5 above the workbench 1. Start the first motor 32. The output shaft of the first motor 32 drives the threaded rod 33 to rotate. The threaded rod 33 drives the slider 34 to move back and forth outside the fixed plate 31. When the inoculation needle body 4 is aligned with the culture dish 5 containing the bacterial culture, start the electric telescopic rod 35. The electric telescopic rod 35 drives the inoculation needle body 4 downwards via the moving block 36, bringing it into contact with the bacterial culture inside the culture dish 5. After collecting an appropriate amount of bacterial culture, start the first motor 32 again, causing the slider 34 to continue sliding forward until the inoculation needle body 4 is aligned with the culture dish 5 containing the culture medium. Inoculate the collected bacterial culture onto the culture medium, completing the inoculation. After inoculation, place the culture dish 5 under suitable temperature and humidity conditions for cultivation. Start the first motor 32 again, bringing the inoculation needle body 4 to the workbench 1. After aligning the inoculation slots, activate the electric telescopic rod 35. The electric telescopic rod 35 moves the inoculation needle body 4 downwards into the cleaning tube 85. Activate the second motor 81. The output shaft of the second motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the first gear 83 to rotate. The first gear 83 drives four sets of second gears 84 to rotate simultaneously, causing the cleaning tube 85 to clean the impurities on the outside of the inoculation needle body 4. After cleaning, activate the electric telescopic rod 35 to move upwards. When the inoculation needle body 4 moves above the cleaning tube 85, activate the spray head 86 to spray alcohol on the inoculation needle body 4 for disinfection. After disinfection, activate the dryer 87 to dry the inoculation needle body 4. After drying, activate the electric telescopic rod 35 to continue moving upwards, waiting for the next inoculation. Excess alcohol flows into the bottom of the collection box 6 and then into the drain pipe 9 through the drain pipe 7. The rotating shaft 82 drives the auger 88 to rotate, carrying the impurities and excess alcohol in the collection cylinder 89 out through the drain pipe 9 to the outside of the collection box 6, completing the cleaning process.
