[0057] Embodiment 2, as Figure 2 、 Figure 3 and Figures 7 - 12 shown, a granular feed quality detection device proposed by the present invention. Compared with Embodiment 1, the demisting mechanism of this embodiment includes an active component, a driven component, a reset unit, a first scraping strip 28, a first rack 29, a gear 32, a second rack 33, a second scraping strip 34 and a perforation 35.

[0059] The active component includes a protection portion 19, a driving device two 20 and an L-shaped rod 21;

[0060] The protection portion 19 is installed on the first rod 4, the driving device two 20 is installed inside the protection portion 19 and its output end is drivingly connected to the L-shaped rod 21; there are multiple protection portions 19, driving devices two 20 and L-shaped rods 21, and multiple protection portions 19, driving devices two 20 and L-shaped rods 21 respectively correspond to the placement components one by one; when it is necessary to scrape the water mist, the driving device two 20 drives the L-shaped rod 21 to extend to the longest position, the first rod 4 drives the L-shaped rod 21 to rotate, and the L-shaped rod 21 drives the driven component to move.

[0061] The driven component includes an installation groove 23, a third runner 24, a second plate 25, an elastic member 26 and a triangular rod 27;

[0062] The elastic member 26 is composed of a third spring and a telescopic rod, and the telescopic rod is located inside the third spring.

[0063] The installation groove 23 is formed on the inner side of the sealing door 2. There are two third runners 24, which are respectively installed on the second rack 33 and the second plate 25.

When the triangular rod 27 moves a certain distance and the first scraping strip 28 and the second scraping strip 34 scrape off the water mist on the observation window 22, the first rack 29 and the second rack 33 are blocked by the gear 32 and cannot move anymore. At this time, the triangular rod 27 continues to be pulled by the L rod 21. However, since the upper part of the triangular rod 27 is a slope, the L rod 21 and the triangular rod 27 will slide, and at the same time, the elastic contraction of the elastic member 26 causes it to descend and separate from the L rod 21.

[0066] Embodiment 3, as Figures 1 - 12 shown, a method for detecting the quality of granular feed proposed by the present invention uses the granular feed quality detection device described in Embodiment 2, and includes the following specific steps:

[0067] S1. Put the processed granular feed sample into a culture dish, then open the sealing door 2, place the culture dish for culturing microorganisms in the placement component, and then maintain a suitable culture environment through the incubator 1.

[0068] S2. When it is necessary to observe the culture dish through the observation window 22, start the first driving device 3 to drive the first rod 4 to rotate, and then drive one of the placement components to enter the guiding groove 13 on the bending part 12 along the guiding groove 13 on the guiding part 11 through the first runner 10. The bending of the bending part 12 drives the placement component to tilt towards the lower part of the bending part 12. At this time, the placement component will elongate due to the downward tilt.

[0069] S3. The elongation of the placement component drives the clamping component to clamp the culture dish. At this time, the staff can observe the culture dish through the observation window 22.

[0070] S4. When the humidity inside the incubator 1 is relatively high, start the second driving device 20 to drive the L rod 21 to extend to the longest position. When the first rod 4 rotates to drive the active component to drive the driven component to move, and then drive the first rack 29 to move towards the direction of the gear 32. Then, through the rotation of the gear 32, drive the second rack 33 to move towards the direction of the gear 32, thereby driving the first wiper strip 28 and the second wiper strip 34 to scrape off the water mist on the observation window 22.

[0071] S5. After scraping off the water mist, drive the first wiper strip 28 and the second wiper strip 34 to reset through the reset unit.

[0072] S6. After the cultivation is completed, the staff takes out the culture dish for subsequent detection and analysis.

[0073] In summary, in the present invention, after making the granular feed into a suitable sample, put it into the culture dish, and then place the culture dish in the inner cavity of the placement groove 18. Then, maintain a suitable cultivation environment through the incubator 1. When it is necessary to observe the culture dish, start the first driving device 3 to drive the first rod 4 to rotate. Through the rotation of the first rod 4, drive the first plate 8 to slide in the guiding groove 13 of the guiding part 11 through the first runner 10. When the first runner 10 slides into the guiding groove 13 of the bending part 12 along the guiding groove 13 of the guiding part 11, drive the first plate 8 to tilt downward relative to the sealing door 2 with the second hinge part 9 as the axis through the bending of the bending part 12.

[0074] When the first plate 8 tilts, it will be pulled towards the bending part 12. At this time, the first spring 7 is stretched, and the first plate 8 will move away from the first hinge part 5. At this time, there is a relative displacement between the protruding part 14 and the first plate 8. Then, through the protruding part 14, push the second runner 16 towards the direction of the second spring 15, and then push the anti-slip plate 17 towards the direction of the placement groove 18, thereby clamping and fixing the culture dish in the inner cavity of the placement groove 18 through the anti-slip plate 17. Thus, while making it convenient for the staff to observe the tilted culture dish, the culture dish is clamped and fixed to prevent the culture dish from falling.

[0075] When the inside of the incubator 1 is in a high-humidity environment or there is water mist on the inner side of the observation window 22 due to other reasons, start the second driving device 20 to drive the L rod 21 to extend to the longest state. When the first rod 4 rotates, drive the L rod 21 to contact the triangular rod 27, and pull the triangular rod 27 to move along the axis direction of the installation groove 23, thereby driving the first rack 29 at the bottom end of the second plate 25 to move towards the direction of the gear 32. Through the meshing of the first rack 29 and the gear 32, drive the gear 32 to rotate. Then, through the meshing of the gear 32 and the second rack 33, drive the second rack 33 to move towards the direction of the gear 32, so that the first wiper strip 28 and the second wiper strip 34 move towards the direction of the gear 32 to scrape off the water mist on the inner side of the observation window 22, thus avoiding the situation that the staff is not convenient to observe the culture dish due to large water mist.

[0076] When the first squeegee 28 and the second squeegee 34 reach the gear 32, the triangular rod 27 is blocked from moving, and thus elastically descends through the elastic member 26. At this time, the gear 32 is driven to rotate in the reverse direction by the elasticity of the torsion spring 31, and then the first squeegee 28 and the second squeegee 34 are driven to reset along the axial direction of the installation groove 23.

[0077] After the observation is over, the first rod 4 drives the first plate 8 to slide along the guide groove 13 on the bending portion 12 to the guide groove 13 on the guiding portion 11 through the first runner 10, thereby driving the first plate 8 to move upward and reset. After the second runner 16 loses the extrusion of the protruding portion 14, the anti-slip plate 17 is driven to reset by the elasticity of the second spring 15, and then no longer clamps the culture dish in the inner cavity of the placement groove 18, thus realizing clamping the culture dish when tilted and not clamping it usually, which is convenient for the staff to take the culture dish.

[0078] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
