Specifically, the sampling structure 32 includes: a vertical mounting body 321 fixed to the top surface of the bottle cap body 31; a conveying pipeline 322 penetrating the vertical installation body 321; a filter pipe 323 connected to the feed pipe 322 and provided on the bottom surface of the bottle cap body 31; wherein, the sliding sleeve 42 cover is established on vertical installation body 321, and conveying line 322 top intercommunication gas detection equipment, and filter 323 bottom is provided with filter head 3231, and filter head 3231 is inside to be filled with air filter.

In this embodiment, when the bottle cap 31 closes the mouth of the culture bottle 2, the whole filter pipeline 323 is located in the culture bottle 2, and when the gas detection device performs regular and quantitative sampling, air in the culture bottle 2 firstly enters the filter pipeline 323 through the filter head 3231, then enters the conveying pipeline 322, and finally enters the gas detection device; the air filter element filled in the filter head 3231 can prevent residue from entering the pipeline and blocking the pipeline.

Specifically, the bottom of the lifting structure 41 is provided with a rotating structure 44 mounted on the rotating disc assembly 1, and the rotating structure 44 is used for driving the lifting structure 41 to rotate.

In this embodiment, it should be noted that the entire structure around the bottle cap body 31 is lifted by the lifting structure 41, but at this time, since the bottle cap body 31 is located above the culture bottle 2, sampling and measurement of other substances such as soil inside the culture bottle 2 are also affected to a certain extent, and therefore, the lifting structure 41 is driven to rotate by the rotating structure 44, so that the bottle cap body 31 is moved out of the culture bottle 2, thereby further improving the measurement operation experience.

Specifically, the rotating disc assembly 1 comprises a vertically arranged rotating mounting shaft 11, and a first supporting part 12, a second supporting part 13 and a third supporting part 14 are horizontally arranged on the side surface of the rotating mounting shaft 11 from bottom to top in sequence; wherein, the rotation installation axle 11 is used for driving first supporting part 12, second supporting part 13 and third supporting part 14 after rotating and rotates together, sets up lid subassembly 4 on the first supporting part 12, sets up blake bottle 2 on the second supporting part 13, and the card is equipped with blake bottle 2 on the third supporting part 14.

In this embodiment, it should be noted that the rotating shaft 11 is connected with a driving motor, the first supporting portion 12 is mainly used to support the whole cap assembly 4, the second supporting portion 13 is used to support the whole culture bottle 2 and part of the sealed sampling assembly 3, and the third supporting portion 14 is used to surround the culture bottle 2, so as to ensure the stability of the culture bottle 2 during the rotating process.

Specifically, the bottom of the culture bottle 2 is provided with a weighing assembly 5 in contact, the weighing assembly 5 is fixed on a first support part 12 and penetrates through a second support part 13, and the weighing assembly 5 is used for measuring the weight of the culture bottle 2 in real time.

In the present embodiment, the weighing unit 5 is located at the bottom of the culture bottle 2 and rotates along with the entire second support part 13, thereby measuring the weight of the culture bottle 2 in real time.

Specifically, the weighing assembly 5 includes a load cell 52 erected on the first support portion 12 and a horizontal sliding plate 51 penetrated on the second support portion 13, the top surface of the horizontal sliding plate 51 contacts the culture bottle 2, and the bottom surface of the horizontal sliding plate 51 contacts the load cell 52.

In the present embodiment, the change in the gravity of the culture bottle 2 changes the height of the horizontal slide plate 51, and the deformation of the detection element inside the load cell 52 generates an electrical signal representing weight information.

Specifically, still include mounting box 6, carousel subassembly 1 sets up in mounting box 6, and mounting box 6 inner wall is provided with light source group 61.

In this embodiment, it should be noted that the light source group 61 is connected to a control module, the control module can simulate the external illumination intensity to automatically adjust the brightness of the light source, when the rotating disc assembly 1 starts to rotate, the illuminated angle of the culture bottle 2 can be changed, and the lighting state of the culture bottle 2 under natural conditions can be further simulated; the control module can also adjust the real-time temperature in the installation box, preferably, the temperature of the culture bottle 2 is raised or lowered through an air conditioner or other elements, so as to simulate the temperature of the culture bottle 2 under the natural condition; further, the control module can supplement water in the culture bottle 2 according to the weighing result of the weighing component 5, so that the water in the culture bottle 2 is kept balanced.
