[0030] In the embodiments of the present disclosure, as shown in Figure 5 and Figure 6 , a cylindrical protruding block is arranged at the middle position of the top of the rotating block 10, and the inner diameter of the cylindrical protruding block is greater than the inner diameter of the circular groove arranged at the middle position of the bottom circular plate of the culture dish 12, and during use, the two multi-section electric cylinders 8 can be controlled to synchronously extend to push the second motor 9 and the rotating block 10 to move upward, and during the upward movement of the rotating block 10, the cylindrical protruding block at the top of the rotating block 10 can be embedded into the circular groove at the middle position of the bottom circular plate of the culture dish 12, so as to ensure the stability of the support of the culture dish 12.
[0031] In the embodiments of the present disclosure, as shown in Figure 2 , two round rods are arranged on the inner bottom side of the incubator 1, two circular holes with the same inner diameter as the outer diameter of the round rods are arranged on the front and back sides of the support plate 3, and when the first lead screw 5 rotates, the support plate 3 can slide leftward and rightward under the support of the round rods on the inner bottom side of the incubator 1 through threads, so as to ensure the stability of the sliding of the support plate 3.
[0032] In the embodiments of the present disclosure, as shown in Figure 3As shown, when the second motor 9 moves down to the bottom, the top surface of the rotating block 10 will be below the bottom surface of the culture dish holder 11. After the counting of the microbial colonies is completed, the multi-section electric cylinder 8 can be controlled to retract to drive the rotating block 10 and the culture dish 12 to move down, and finally the rotating block 10 will be below the bottom surface of the culture dish holder 11. Therefore, the left and right positions of the support plate 3, the second motor 9 and the rotating block 10 can be adjusted, and then the other culture dishes 12 can be pushed up for counting.
[0033] In the embodiments of the present disclosure, as shown in Figures 1-4 As shown, the middle part of the culture dish holder 11 is composed of two arc-shaped rods arranged symmetrically left and right, and the inner diameter of the opening between the arc-shaped rods is 2mm larger than the outer diameter of the bottom circular plate of the culture dish 12. After the counting of the microbial colonies is completed, the multi-section electric cylinder 8 can be controlled to retract to drive the rotating block 10 and the culture dish 12 to move down. During this process, the bottom surface of the culture dish 12 will be in close contact with the top surface of the culture dish holder 11, and the circular plate at the bottom of the culture dish 12 will be embedded in the opening between the arc-shaped rods in the middle part of the culture dish holder 11, so as to avoid the culture dish 12 from falling off due to horizontal movement.
[0034] In the embodiments of the present disclosure, as shown in Figures 1-4 As shown, an opening is provided on the inner side of the culture dish holder 11, and the second motor 9 and the rotating block 10 can move up and down in the opening on the inner side of the culture dish holder 11. Therefore, the height of the culture dish 12 can be adjusted.
[0035] In the embodiments of the present disclosure, as shown in Figures 1-6 As shown, the camera fixing block 7 is located directly above the rotating block 10, and the outer side of the cylindrical protruding block at the top of the rotating block 10 is wrapped with a layer of rubber. Therefore, when the rotating block 10 pushes the culture dish 12 up, it can be ensured that the culture dish 12 moves to the bottom of the camera. During shooting, the second motor 9 can be controlled to drive the rotating block 10 and the culture dish 12 to rotate synchronously, so as to adjust the shooting position. During this process, the rubber on the outer side of the cylindrical protruding block at the top of the rotating block 10 can increase the friction between the contact surface and the culture dish 12, so as to ensure that the culture dish 12 can rotate synchronously.
[0036] The working principle of the embodiment is as follows: during installation, the incubator 1 can be placed in a culture room, and then the camera at the bottom of the camera fixing block 7 can be wirelessly connected to an external display screen; when microbial colony culture and counting are needed, the box door 2 is first opened, then the culture dish 12 is placed on the top of the culture dish support 11, and then the box door 2 is closed and locked, so that the microbial colony can be cultured in a closed manner; when the microbial colony culture is completed and counting is needed, the first motor 4 is first controlled to drive the first lead screw 5 and the second lead screw 6 to rotate synchronously; when the first lead screw 5 rotates, the supporting plate 3 will slide left and right under the support of the inner side round rod at the bottom of the incubator 1 through the thread, so that the second motor 9 and the rotating block 10 above the supporting plate 3 can be adjusted to be located directly below one of the culture dishes 12, and at the same time, the camera fixing block 7 and the camera at the bottom thereof can be moved to be located directly above the culture dish 12 through the thread of the second lead screw 6; then the two multi-section electric cylinders 8 are controlled to extend synchronously to push the second motor 9 and the rotating block 10 upwards; during the upward movement of the rotating block 10, the cylindrical protruding block at the top of the rotating block 10 will be embedded in the circular groove at the middle position of the bottom circular plate of the culture dish 12, and then the rotating block 10 will push the culture dish 12 to move upwards synchronously; when the multi-section electric cylinders 8 push the rotating block 10 to move to the topmost position, the distance between the culture dish 12 and the camera is close, so that the microbial colony can be photographed by the camera, and then counted through the external display screen; during the photographing, the second motor 9 can be controlled to drive the rotating block 10 and the culture dish 12 to rotate synchronously, so that the photographing position can be adjusted; after the counting of the microbial colony is completed, the multi-section electric cylinders 8 are controlled to retract to drive the rotating block 10 and the culture dish 12 to move downwards; during the process, the bottom surface of the culture dish 12 will be tightly attached to the top surface of the culture dish support 11, and the circular plate at the bottom of the culture dish 12 will be embedded in the opening between the arc-shaped rods in the middle part of the culture dish support 11, so that the culture dish 12 can be prevented from falling off due to horizontal movement; finally, the rotating block 10 will be located below the bottom surface of the culture dish support 11, so that the left and right positions of the supporting plate 3 and the second motor 9 and the rotating block 10 can be adjusted, and then other culture dishes 12 can be pushed upwards for counting.
