[0025] In the embodiment one, the width of the buffer plate one 215 and the buffer plate two 216 is equal to the width of the inclined plate 211, the length of the buffer plate one 215 and the buffer plate two 216 is half of the length of the inclined plate 211, the buffer plate one 215 is arranged at a specific 40° angle with the top plate of the dust cover 21, the buffer plate two 216 is arranged at a specific 20° angle with the top plate of the dust cover 21, the buffer plate two 216 is provided with a buffer plate three 217 at the bottom end, the buffer plate three 217 is connected to the bottom end of the buffer plate two 216 in a movable connection manner through a spring damper, wherein the angle between the buffer plate three 217 and the top plate of the dust cover 21 is within a specific range of 30° to 40°, and the buffer plate one 215, the buffer plate two 216 and the buffer plate three 217 are all provided with rubber buffer pads at the top;
[0026] Specifically, the buffer plate one 215 is arranged at a specific 40° angle with the top plate of the dust cover 21, which can effectively guide the sliding direction of the raw coal and preliminarily buffer the potential energy of the falling raw coal, so as to reduce the impact force of the raw coal on the subsequent part of the buffer structure, and play a key role in the initial guiding and preliminary buffering function in the dust prevention system. The buffer plate two 216 is arranged at a 20° angle with the top plate of the dust cover 21, which cooperates with the angle of the buffer plate one 215. After the raw coal is preliminarily buffered by the buffer plate one 215, the sliding speed and trajectory of the raw coal can be further adjusted on the buffer plate two 216, so that the raw coal can continue to move to the inside of the coal washer in a more stable and orderly state, thereby greatly reducing the dust phenomenon caused by the direct falling of the raw coal, and effectively improving the dust prevention effect during the feeding process of the coal washer. When the raw coal slides to the buffer plate three 217 through the buffer plate two 216, the spring damper can be stretched and buffered to a certain extent according to the impact force of the raw coal, so as to further adjust the falling speed and force of the raw coal, and make the raw coal fall to the spiral buffer plate more stably.
[0027] In the embodiment two, the dust cover 21 is in an inverted trapezoidal structure, the bottom plate of the dust cover 21 is connected to the top of the buffer cylinder 22, and the side of the top plate of the dust cover 21 close to the feeding port 213 is provided with a downward inclined buffer plate four 218, the buffer plate four 218 is arranged at a specific 140° angle with the top plate of the dust cover 21, a plurality of through holes 2181 are uniformly and spacedly arranged on the buffer plate four 218, and the buffer plate four 218 is provided with a rubber buffer pad at the top;
[0028] Specifically, when the raw coal is put in, part of the raw coal will first contact the buffer plate four 218, which plays a role in buffering and guiding the raw coal to slide in the direction of the inclined plate 211. At the same time, the arrangement of the through holes 2181 is also helpful for air circulation, so that the dust generated at the feeding port 101 can be timely sucked away, and the whole dust prevention and buffer system can better play a role.
[0029] Working principle:
[0030] First, when raw coal enters from the top feed inlet 101 of the main body 1 of the coal washing machine, it will fall onto the buffer plate 215. Since the buffer plate 215 and the top plate of the dust cover 21 form a 40° angle, the raw coal slides down along this inclined angle. During the sliding process, its falling potential energy is initially buffered, the falling speed is slowed down, and the flow direction of the raw coal is initially guided to a specific path, reducing the possibility of the raw coal directly impacting the components below and generating a large amount of dust.
[0031] Secondly, after being buffered by buffer plate 215, the raw coal slides to buffer plate 216. Buffer plate 216 forms a 20° angle with the top plate of dust cover 21. This angle works in conjunction with the angle of buffer plate 215, allowing the raw coal to further adjust its sliding speed and trajectory on buffer plate 216. At this time, the movement of the raw coal on buffer plate 216 is relatively more stable, and its kinetic energy is further dispersed and weakened, further reducing the probability of dust generation due to violent collisions.
[0032] Finally, when the raw coal slides from buffer plate 216 to buffer plate 217, buffer plate 217 is movably connected to the bottom end of buffer plate 216 via a spring damper. The angle between buffer plate 217 and the top plate of dust cover 21 is between 30° and 40°. When the raw coal impacts buffer plate 217, the spring damper activates, absorbing some of the remaining kinetic energy of the raw coal, allowing it to enter the subsequent processing stage of the coal washing machine in a very gentle manner. Through the coordinated action of this series of buffer plates 215, 216, and 217... With the same function, starting from the raw coal entering the feed inlet 101, the generation of excessive dust during the falling process of the raw coal is gradually and effectively controlled. In addition, during the falling process of the raw coal, the air inside the dust cover 21 will have a certain flow due to the falling of the raw coal. By connecting the existing dust collection equipment at the dust collection pipe installation port 212, the dust generated inside the dust cover 21 due to the falling of the raw coal and other factors can be sucked away in time, keeping the air inside the dust cover 21 relatively clean, enhancing the dust prevention effect, and creating a relatively low dust working environment for the coal washing machine. At this point, the entire process is completed.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
