[0028] Referring to Figure 6In the embodiment, the conveying assembly comprises a flow guide pipe 501, a collection box 502, a fan 503 and a filter plate 504. The flow guide pipe 501 is fixedly installed at a position matched with the collection assembly on the inner wall of the rear end of the box body 1. The rear end of the flow guide pipe 501 extends through the box body 1 to the outside, and the collection box 502 for collecting spores is fixedly connected to the outside. The end of the collection box 502 away from the box body 1 is embeddedly installed with the fan 503 for sucking air with spores outside into the collection box 502. The outside of the fan 503 is fixedly installed with the filter plate 504 for blocking impurity particles in the outside air.

[0029] In operation, first, the device is moved to a corresponding position, and the box door 6 is closed, so that the box body 1 is in a sealed state.

[0030] Then, the switch of the corresponding assembly is controlled to be opened through the control panel 7, and the collection of spores is started.

[0031] First, the spores are sucked into the box body 1 through the conveying assembly. The fan 503 sucks air outside into the collection box 502 by using wind power. In the collection process, the filter plate 504 blocks dust particles outside, so that the spores without dust particles enter the flow guide pipe 501 from the collection box 502, and pass through the flow guide pipe 501 to hit the surface of the second adhesive tape 309 of the collection assembly.

[0032] In the process of collecting spores, the driving motor 307 drives the driving wheel 302 to rotate, drives the first adhesive tape 308 and the second adhesive tape 309 to move, and drives the adhesive tape wheel 301 to synchronously rotate and link with the driving wheel 302, so that the adhesive tape moves forward at a regular time and distance. When the adhesive tape collecting spores reaches the counter 305 of the counting wheel 304, the number of rotations is calculated by the counting wheel 304, and the microscope picture of the spores on the adhesive tape is scanned by the scanning gun head 306 one by one, and the counting information is transmitted to the counter 305 for recording.

[0033] When the focal length of the objective lens 205 needs to be adjusted, the imaging focal length of the objective lens 205 is adjusted by remotely controlling the coarse focus screw and the fine focus screw of the connection module 203 through the remote terminal device, and different imaging effects are completed, and the imaging picture is transmitted to the remote terminal device through the transmission module.

[0034] When the lens of the objective lens 205 is contaminated and needs to be cleaned, the self-cleaning assembly is used for automatic cleaning. The outside air is introduced into the air pressure pump 401 through the air inlet pipe 403, and the air pressure is adjusted to an appropriate size by the air pressure controller 404, so that the gas reaches the air injection tower 402 through the connecting pipe 405, and the dust particles adhered to the lens are blown off from the air injection tower 402.

[0035] When the spores are collected, and laboratory analysis is required, open the box door 6, adjust the counter 305 to return the tape, select the part to be analyzed, tear off the second tape 309 outside the first tape 308 which has collected spores, and then adjust the counter to return the tape to its original position, and then take it back to the laboratory for further analysis.

[0036] Through the above steps, the imaging focal length of the objective lens 205 is controlled by the microscopic imaging assembly which can remotely control the coarse focus screw and the fine focus screw to achieve remote focusing, without on-site operation. The collection assembly with double tape structure is set to collect spores, when laboratory analysis is required, the outer tape can be directly torn off and taken back to the laboratory for further analysis. The self-cleaning assembly is set to automatically clean the lens of the objective lens 205 when the imaging image is not clear, so as to ensure the imaging effect. The transmission assembly is set to more concentratedly guide the spores to the tape, so that the collection effect of the spores is better. The existing spore trap can usually only observe the spore image or adjust the microscope on site, the tape for capturing spores is usually set as a single fixed structure, when laboratory analysis of spores is required, sampling is more tedious, and the lens of the objective lens 205 used for spore imaging is prone to be contaminated with dust during work, resulting in a decline in imaging effect.
