The collecting assembly includes a collecting box 5, which is slidably connected to the bottom of the inner wall of the base 1. The bottom of the inner wall of the base 1 is symmetrically fixedly connected with a slide rail 6. The bottom of the collecting box 5 is symmetrically provided with a slide groove 7. The top of the collecting box 5 is slidably connected with a cover plate 8.

[0023] In the above technical solution, considering that there is a certain amount of residue left on the burning plate, it will affect the combustion density detection of the next material, making the test data inaccurate. Manual cleaning is difficult due to the high temperature. In order to solve this problem, the specific operations are as follows:

[0024] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, during the material combustion process, the staff opens the density detection instrument 2 and the conveying port 3, and the smoke generated by the combustion enters the interior of the density detection instrument 2 through the conveying port 3. The density detection instrument 2 begins to detect the density of the smoke generated by the combustion. After the combustion is completed, the combustion waste needs to be removed from the top of the screening plate 401. The staff starts the motor 408, and the output end of the motor 408 drives the cam 409 to rotate. The cam 409 toggles the roller 407, and the roller 407 drives the screening plate 401 to slide on the outside of the slide bar 405. When the cam 409 is separated from the roller 407, the screening plate 401 is quickly reset under the action of the spring 406. Through the cleaning component, the combustion waste on the top of the screening plate 401 can be cleaned up under the repeated rotation of the cam 409. No manual cleaning is required during the cleaning process, which avoids safety hazards. At the same time, it also ensures the data accuracy of the next density detection. The structure is simple and practical.

[0025] Reference Figure 1 and Figure 4In a preferred embodiment, the front of the base 1 is rotatably connected with an opening and closing door 9, and an observation window 10 is provided inside the opening and closing door 9, and the observation window 10 is made of a transparent material. A hopper 402 is fixedly connected to the top of the screening plate 401. The size of the slide rail 6 is consistent with the size of the slide 7, and the slide rail 6 and the slide 7 are used in conjunction with each other. The length of the collection box 5 is smaller than the internal space scale of the base 1, which provides the necessary space for the operation of the cleaning component. When the cam 409 rotates repeatedly, the waste on the top of the screening plate 401 falls into the interior of the collection box 5 through the screening hole 403. After cleaning, the staff covers the cover plate 8 on the top of the collection box 5, and then pulls out the collection box 5 for cleaning. Through the set collection component, the combustion waste can be quickly collected and cleaned, ensuring the safety and hygiene of the test, and also avoiding the smoke generated by the combustion from affecting the staff who collect the waste.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, a protective cover is fixedly connected to the outside of the motor 408, and heat dissipation holes are equidistantly opened inside the protective cover. A controller 11 is fixedly connected to the front of the density detection instrument 2, and the motor 408 and the controller 11 are electrically connected. Through the controller 11, the staff can control the opening and closing of the motor 408, and the operation is more convenient.

[0027] Working principle: In actual use, the staff first places the material to be burned and tested on the top of the screening plate 401, and then ignites the material. During the burning process of the material, the staff opens the density detection instrument 2 and the conveying port 3, and the smoke generated by the burning enters the interior of the density detection instrument 2 through the conveying port 3. The density detection instrument 2 begins to detect the density of the smoke generated by the burning. After the burning is completed, the burning waste needs to be removed from the top of the screening plate 401. The staff starts the motor 408, and the output end of the motor 408 drives the cam 409 to rotate. The cam 409 moves the roller 407, and the roller 407 drives the screening plate 401 to slide on the outside of the slide bar 405. When the cam 409 is disengaged from the roller 407, the screening plate 401 is quickly reset under the action of the spring 406. Under the repeated rotation of the cam 409, the waste on the top of the screening plate 401 falls into the interior of the collecting box 5 through the screening hole 403. After cleaning, the staff covers the top of the collecting box 5 with the cover plate 8, and then pulls out the collecting box 5 for cleaning. At this point, the staff has completed the detection of smoke density.

[0028] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
