[0007] As a further improvement to the above technical solution:
[0008] The number of limiting grooves is multiple and they are distributed in a matrix on the shelf.
[0009] Each of the limiting grooves includes multiple receiving cavities, which are distributed in a stepped manner.
[0010] The lighting module includes a mounting bracket located on the top of the housing, and the mounting bracket is provided with multiple lighting lamps corresponding to the positions of each limiting slot.

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0024] like Figure 1-2As shown, the device for convenient and rapid counting of total colonies on a plate in this embodiment includes a box 1 and a cabinet door 18 located on the side wall of the box 1. A control module 2 is provided on the top of the box 1. The control module 2 includes a display, a control panel, and an information processor, which is used to control the image acquisition operation and provide data feedback. A support base 3 is provided inside the box 1. A lighting module is provided on the upper part of the box 1. An image acquisition module is provided on the inner side wall of the box 1. A shelf 4 is provided on the upper part of the support base 3. The upper surface of the shelf 4 is provided with limiting grooves 5 for placing the counting plates. There are multiple limiting grooves 5, which are distributed in a matrix on the shelf 4. Each limiting groove 5 includes multiple receiving cavities 6, which are distributed in a stepped manner. Compared with existing detection equipment, the design of multiple limiting grooves 5 enables simultaneous detection and counting of multiple samples during use. At the same time, it can also perform batch detection of different types of counting plates, improving work efficiency.
[0025] like Figure 3 As shown, the lighting module includes a mounting bracket 7 located on the top of the housing 1. The mounting bracket 7 is equipped with multiple lighting lamps 8 that correspond to the positions of each limiting groove 5. The lighting lamps 8 are used to illuminate each limiting groove 5 to facilitate image acquisition.
[0026] like Figure 4 As shown, the image acquisition module includes a cross brace 9 installed on the inner side wall of the housing 1. A camera 10 is installed on the cross brace 9, and a mounting bracket 11 for installing the camera 10 is provided on the cross brace 9. There are multiple cameras 10 and they are evenly distributed along the length of the cross brace 9. The number of cameras 10 is the same as the number of columns of the matrix formed by the shelf 4. During batch acquisition, the movement of the cross brace 9 can realize the simultaneous acquisition of multiple counting boards at different positions, thereby improving the acquisition efficiency.
[0027] The mounting bracket 11 includes an adjusting seat 12 that is slidably connected to the cross brace 9. The adjusting seat 12 is provided with a clip 13 for fixing the camera 10. The adjusting seat 12 and the clip 13 are connected by an adjusting rod 14. The adjusting rod 14 is made of flexible material. The position of the camera 10 is adjusted by adjusting the adjusting seat 12 so that it corresponds to the position of the limiting groove 5. The flexible material of the adjusting rod 14 allows for easy adjustment of the angle of the camera 10. During image acquisition, the camera 10 is tilted on one side above the limiting groove 5 to avoid shadows in the limiting groove 5 after blocking light, which would affect the sampling and counting operations.
[0028] A telescopic cylinder 15 connected to the cross brace 9 is installed on the side wall of the housing 1. Guide rods 16 are installed on both sides of the telescopic cylinder 15. The cross brace 9 has through holes corresponding to the positions of the guide rods 16. When the telescopic cylinder 15 adjusts the cross brace 9 to move forward or reset, the guide rods 16 can ensure the stability of the displacement of the cross brace 9.
[0029] like Figure 5 As shown, the shelf 4 and the support base 3 are detachably connected. When placing the counting board, the shelf 4 can be removed from the box 1. The upper surface of the support base 3 is equipped with a disinfection lamp 17. The shelf 4 is made of transparent material, and the disinfection lamp 17 is an ultraviolet lamp. By laying the disinfection lamp 17 on the upper surface of the support base 3, the inside of the box 1 is disinfected to ensure that the working environment is not polluted.
