[0022] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the coal can be burned on the top of the first combustion bottom plate 8 and the second combustion bottom plate 10 by the support of the first electric telescopic rod 3 and the second electric telescopic rod 7. After the combustion is completed, the output ends of the second electric telescopic rod 7 and the first electric telescopic rod 3 are controlled to contract, thereby driving the first combustion bottom plate 8 and the second combustion bottom plate 10 to rotate, so that the coal slag on the top of the first combustion bottom plate 8 and the second combustion bottom plate 10 falls into the interior of the storage groove 28. Since the interior of the storage groove 28 is movably installed with an ash hopper 4, the coal slag will fall into the interior of the ash hopper 4, and then the rotation of the output end of the first motor 17 drives the installation groove 1 6, the two sprocket shafts 18 inside rotate, and the rotation of the two sprocket shafts 18 can simultaneously drive the two screw rods 5 to rotate, and the rotation of the two screw rods 5 can drive the slider 6 to slide along the installation direction of the screw rod 5.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the coordinated use of the first sealing baffle 26 and the second sealing baffle 27 can ensure that the first combustion bottom plate 8 and the second combustion bottom plate 10 can be opened and closed normally, and prevent the coal from falling into the ash hopper 4. The support frame 15 welded at the bottom of the base 1 can stably place the entire device on the ground, and then the coal is thrown into the feed bin 23 from the coal feeding port 24, and then the dragon 22 is driven to rotate by the rotation of the output end of the mounting groove 16, so that the coal entering the feed bin 23 is transported to one side of the coal feeding port 21, and then enters the furnace 9 through the coal feeding port 21 to be burned, and then the exhaust fan 14 can drive the gas flow, so that the flue gas generated inside the base 1 is drawn into the electrostatic precipitator 13 through the air pipe 11 for purification, thereby collecting the fly ash in the flue gas, and then discharging it through the smoke exhaust pipe 12.
[0025] Working principle: When in use, the coal is put into the feed bin 23 from the coal-feeding port 24, and then the rotation of the output end of the mounting groove 16 drives the dragon 22 to rotate, so that the coal entering the feed bin 23 is transported to one side of the coal-feeding port 21, and then enters the furnace 9 through the coal-feeding port 21 to be burned. The coal can be burned on the top of the first combustion bottom plate 8 and the second combustion bottom plate 10 through the support of the first electric telescopic rod 3 and the second electric telescopic rod 7.

Through this device, it is convenient for the operator to quickly collect the coal slag, so that it is convenient for the tester to detect the carbon oxidation rate.
