[0022] (1) By setting the feeding channel, the discharging channel, the baffle, the support mechanism and the placement assembly, the culture dish is placed in the placement assembly, and then the corresponding baffle is opened to send the culture dish into the machine shell for detection, which can reduce the air exchange between the machine shell and the outside, thereby reducing the probability of external microorganisms entering the machine shell and ensuring the accuracy of the detection result;

[0023] (2) By setting up a lighting mechanism, a support mechanism and a linkage component, when the petri dish is being detected, it is driven by an electric push to lift off the conveyor belt and rise to the standard detection height. And when detailed observation or regional observation is needed, the height of the petri dish can be changed with the change of the installation guard plate, meeting different detection requirements;

[0024] (3) By setting up a linkage component, which consists of structural components such as a wedge block, a fixed block and an elastic pull rope, compared with the comparative document, the structure of the linkage component in this application is simpler, without complex gear transmission and is more convenient to maintain.

[0041] Refer to Figures 1-7 , A detection method for a microorganism detection system includes the following steps:

[0042] S1. Disinfect the interiors of the machine shell 1, the feeding channel 4 and the discharging channel 5. Place the culture dish 13 containing the sample in the placement ring 1202 of the placement assembly 12. Pull the baffle 7 on the feeding channel 4, place the culture dish 13 on the conveyor belt 8, and send the culture dish 13 into the machine shell 1;

[0043] S2. When the guide block 1201 of the placement assembly 12 enters the U-shaped clamping block 11, turn off the conveyor belt 8, start the electric push rod 9 to drive the U-shaped clamping block 11 to rise, so that the culture dish 13 rises to the standard detection height, and then the sample can be carefully observed through the observation mirror 3. The observed image can be displayed in real time on the screen of the detector 2;

[0044] S3. If it is necessary to closely observe the sample microorganisms, start the motor 14 to drive the bidirectional screw 15 to rotate, so that the two mounting guard plates 18 approach each other, and the U-shaped clamping block 11 and the culture dish 13 rise through the linkage assembly, then the sample can be observed at a close distance. If it is necessary to observe the sample regionally, control the bidirectional screw 15 to reverse. Similarly, the two mounting guard plates 18 move away from each other, and the height of the culture dish 13 decreases, and a wide and comprehensive observation of the sample can be carried out;

[0045] S4. After the detection is completed, the electric push rod 9 drives the U-shaped clamping block 11 and the culture dish 13 to reset, start the conveyor belt 8 again, send the detected culture dish 13 out of the machine shell 1 through the discharging channel 5, and then open the baffle 7 on the discharging channel 5 to take out the culture dish 13.

[0046] Working principle of the present invention: The interior of the machine housing 1, the feeding channel 4 and the discharging channel 5 is disinfected by a disinfection lamp to keep the interior of the equipment sterile. The culture dish 13 containing the sample is placed in the placement ring 1202 of the placement assembly 12. Pull the baffle 7 on the feeding channel 4, place the culture dish 13 on the conveyor belt 8, and send the culture dish 13 into the machine housing 1. Then release the baffle 7, and the baffle 7 blocks the feeding port 6 to reduce the air exchange inside and outside. When the guiding block 1201 of the placement assembly 12 enters the U-shaped block 11, turn off the conveyor belt 8, start the electric push rod 9 to drive the U-shaped block 11 to rise, so that the culture dish 13 rises to the standard detection height. At this time, the culture dish 14 is in a suspended state, and the sample can be carefully observed through the observation mirror 3. The observed image can be displayed in real time on the screen of the detector 2;

[0047] During the transportation of the culture dish, as Figure 6 shown, the elastic pull rope 21 is in a relaxed state. When the culture dish 13 rises to the standard detection height, the elastic tension 21 is in a taut state, as Figure 7 shown. At this time, one end of the wedge-shaped insert 20 is at the same height as the rectangular jack 23. If it is necessary to observe the sample microorganisms closely, start the motor 14 to drive the bidirectional screw 15 to rotate, so that the two mounting guards 18 approach each other, and the wedge-shaped insert 20 gradually enters the rectangular jack 23, causing the fixed block 22 and the U-shaped block 11 to rise, and the spring telescopic rod 10 is stretched, thereby driving the culture dish 13 to rise, and the sample can be observed closely. If it is necessary to observe the sample regionally, control the bidirectional screw 15 to reverse, the two mounting guards 18 move away from each other, and under the action of the elastic pull rope 21, the U-shaped block 11 is pulled down to squeeze the spring telescopic rod 10, and the height of the culture dish 13 drops, and the sample can be observed widely and comprehensively;

[0048] After the inspection is completed, the mounting guard 18 resets. Under the action of the spring telescopic rod 10, the U-shaped block 11 and the culture dish 14 return to the standard detection height. Then start the electric push rod 9 to lower the culture dish 13 to the initial height, and then start the conveyor belt 8 to send the culture dish 13 out through the discharging channel 5.

[0049] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
