[0034] Working principle: Coal is placed on the conveyor belt body 4 at the end away from the box 18. The first motor 2 is started to transport it. First, it passes through the leveling roller 5, which spreads the accumulated coal evenly as it rotates. It passes under the leveling roller 5 and reaches the first support frame 8. Under the control of the controller 15, the first electric telescopic rod 9 drives the partition plate 10 to descend intermittently, dividing the coal into multiple small areas. The auxiliary roller 7 then spreads and arranges the partitioned coal a second time. Finally, it reaches the second support frame 11. The X-rays emitted by the dual-energy X-ray generator 12 penetrate the coal flow layer and are received by the detector 14 below. The X-rays are then sent to the controller 15. The ash content of the coal flow is calculated based on the attenuation of the X-rays. Then, the second electric telescopic rods 16 on both sides are controlled to adjust their extension lengths, thereby adjusting the positions of the push plates 17 on both sides. The push plate 17 on the side pushes the coal, limiting it to a set of chutes 19, and then it enters the corresponding collection box 20 for collection. The ash content of the coal collected in each set of chutes 19 is preset. For example, coal with an ash content of less than 10% of the partition plate is classified as high-quality coal, coal with an ash content of 10% of the partition plate and 20% of the collection box is classified as ordinary coal, and coal with an ash content of more than 20% of the collection box is classified as gangue, etc., to achieve multi-level sorting and improve efficiency. Pulling the baffle 26 outward causes the fixing rod 25 to slide, and the spring 27 is stretched, sliding the collection box 20 in the chutes 19, so that the connecting plate 23 slides in the slot 22. Releasing the baffle 26, under the action of the spring 27, causes the fixing rod 25 to slide in the fixing hole 24, which makes it easy to quickly fix the collection box 20 in the chutes 19, which facilitates the collection of sorted coal and prevents it from sliding out due to the impact of falling coal, making it more stable.
