[0029] Embodiment one:

[0030] Please refer to Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an auxiliary device for coal quality testing and analysis includes:

[0031] The reducing machine assembly 2, and the feeding assembly 1 located at the top of the reducing machine assembly 2;

[0032] The reducing machine assembly 2 includes a housing 21, and a grinding roller 25 is rotatably mounted inside the housing 21;

[0033] The feeding assembly 1 includes a protective cover 11 hinged to the top of the housing 21. The top of the protective cover 11 is connected to a feeding hopper 17. A protective cover 18 is hinged to the top of the feeding hopper 17. A sealing plate 14 corresponding to the feeding hopper 17 is slidably installed inside the inner wall of the protective cover 11. A movable rod 19 is hinged between the sealing plate 14 and the protective cover 18.

[0034] As can be seen from the above, by flipping the protective cover 18 upwards during use, the sealing plate 14 can be slid to the left by using the movable rod 19, so that the sealing plate 14 can seal the bottom of the feed hopper 17, which can effectively prevent the dust generated when grinding coal samples inside the reducing machine component 2 from flying out, thus avoiding the situation where the surrounding air is polluted and inhaled by the staff, causing harm to their bodies.

[0035] By feeding the next batch of coal samples into the feed hopper 17, the sealing plate 14 can prevent the coal samples from being fed downwards into the housing 21, thus creating a temporary storage effect for the coal samples inside the feed hopper 17. By closing the protective cover 18, the movable rod 19 can be used to push the sealing plate 14 to the right, releasing the sealing effect of the sealing plate 14 on the bottom of the feed hopper 17. This allows the temporarily stored coal samples in the feed hopper 17 to be fed downwards into the housing 21, where they can fall onto the grinding roller 25. By driving the grinding roller 25 to rotate relative to each other, the coal samples can be easily squeezed and ground. After the protective cover 18 is closed, the entrance of the feed hopper 17 is sealed, effectively preventing dust generated inside from flying out during frequent feeding, thus bringing more convenience to the user.

[0036] Depend on Figure 5 and Figure 6 It can be seen that a slider 15 extending out of the protective cover 11 is fixedly installed on the top of the sealing plate 14, and the slider 15 is hinged to the movable rod 19.

[0037] As can be seen from the above, the movable rod 19 can drive the slider 15 to slide along the surface of the protective cover 11, and can simultaneously drive the sealing plate 14 to slide left and right.

[0038] For details, please refer to Figure 5 and Figure 6 As shown, the inner wall of the protective cover 11 has an movable groove 13 for the sealing plate 14 to slide, and the top of the protective cover 11 has a slide rail 12 for the slider 15 to slide. The slide rail 12 is connected to the movable groove 13.

[0039] As can be seen from the above, the sealing plate 14 can be slidable through the movable groove 13, making the sealing plate 14 less prone to shaking. The slider 15 can be limited by the slide rail 12, allowing the slider 15 to slide along the slide rail 12.

[0040] For details, please refer to Figure 3 and Figure 5 As shown, a guide baffle 16 corresponding to the grinding roller 25 is fixedly installed on the inner wall of the protective cover 11, and a handle 111 is fixedly installed on the top of the protective cover 18.

[0041] As can be seen from the above, when the coal sample enters the protective cover 11, the coal sample can be blocked by the guide baffle 16, so that the coal sample can be guided between the grinding rollers 25, making it convenient for the grinding rollers 25 to grind the coal sample. The protective cover 18 can be opened and closed easily by using the handle 111.

[0042] Example 2:

[0043] refer to Figure 2 and Figure 3 As shown, a fixing seat 27 is fixedly installed on one side of the housing 21, and the fixing seat 27 is fixed to the protective cover 11 by a fixing knob 110.

[0044] As can be seen from the above, when the protective cover 11 is closed and the housing 21 is closed, the fixing knob 110 can be used to fix it to the fixing base 27, which can easily fix the protective cover 11. At the same time, the fixing knob 110 can be easily separated from the fixing base 27, and the protective cover 11 can be flipped up and opened, so that the grinding roller 25 can be exposed, making it easier for the staff to clean and maintain the grinding roller 25, bringing more convenience to the maintenance work.

[0045] refer to Figure 4 As shown, a collection box 23 is slidably installed inside the housing 21 at the bottom of the grinding roller 25, and a handle 24 is fixedly installed at the front end of the collection box 23.

[0046] As can be seen from the above, after the coal sample is ground by the grinding roller 25, the ground coal particles can be guided into the collection box 23 below for collection. The collection box 23 can be easily pulled out from the shell 21 using the handle 24, so that the staff can easily take out the coal particles and put them into the coal quality tester for testing.

[0047] refer to Figure 2 and Figure 4 As shown, a motor 26 for powering the grinding roller 25 is fixedly installed at the rear end of the housing 21, and a support frame 22 is connected to the bottom of the housing 21.

[0048] As can be seen from the above, the motor 26 can drive the grinding roller 25 to rotate, so that the grinding roller 25 can grind the coal sample. The support frame 22 can support the reducing machine component 2, so that the device can be placed in a suitable position for use.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
