In the present embodiment, a vibrating motor is arranged in the vibrating block 202, and the vibrating motor can provide a vibration source for the vibrating block 202 after being started.

[0034] A screening mechanism 3 is arranged on the partition 103, the screening mechanism 3 is adjacent to and communicates with the discharge port of the collection plate 201, a weighing mechanism 5 is arranged on the partition 103, a sample preparation machine 4 is arranged on the partition 103, and the sample preparation machine 4 communicates with the feeding end of the weighing mechanism 5, an analysis machine 6 is installed on the side of the box 1 away from the crusher 2, the feeding end of the analysis machine 6 communicates with the discharge end of the weighing mechanism 5, a recycling mechanism 7 is arranged at the bottom of the box 1, and a discharge port 102 is formed in the outer wall of one side of the box 1, the discharge port 102 communicates with the recycling mechanism 7.

[0035] When the coal quality analyzer is used, the coal block to be detected is thrown from the feeding hopper 101, falls into the crusher 2 through the feeding hopper 101, and is crushed by the crusher 2 and then falls onto the collection plate 201. The vibration generated by the vibrating block 202 causes the coal block falling on the collection plate 201 to slide into the screening mechanism 3. The screening mechanism 3 screens the crushed coal block. The coal block with a larger diameter falls into the recovery mechanism 7 and is transported to the discharge port 102. After screening, the coal block is sent to the sample preparation machine 4. After the coal block is prepared into a coal sample by the sample preparation machine 4, the coal sample is discharged and falls into the weighing mechanism 5. The weighing mechanism 5 weighs the coal sample and sends the coal sample to the analyzer 6 when the weight reaches the preset value, completing the sample preparation work of the coal block to be detected.
