[0026] like Figure 5 As shown, two guide seats 316 are symmetrically fixedly connected to the surfaces of the first screening plate 301 and the second screening plate 302.

[0027] like Figure 1 As shown, a transmission plate 303 is fixedly connected to the bottom of the inner shell 1, and two guide seats 316 are also symmetrically fixedly connected to the upper surface of the transmission plate 303.

[0028] A feeding port 4 is fixedly connected to the left side of the outer casing 1, and three discharge ports 5 are provided on the right side of the outer casing 1. All three discharge ports 5 are fixedly connected to the right side of the outer casing 1.

[0029] Working principle: When it is necessary to separate coal impurities, coal is fed into the device through the feed port 4. At this time, the second motor 304 is started. The output end of the second motor 304 drives the first belt drive pulley 306 to rotate. The first belt drive pulley 306 drives the second belt drive pulley 307 to rotate through the conveyor belt 308. At this time, the driven transmission disc 307 drives the rotating disc 309 to rotate. The rotating disc 309 drives the sliding sleeve 310 to reciprocate up and down through the eccentric shaft. The reciprocating up and down movement of the sliding sleeve 310 drives the support rod 311 to reciprocate. The support rod 311 drives the second belt drive pulley 307 to reciprocate. The first screening plate 301 and the second screening plate 302 reciprocate up and down. At this time, the holes on the first screening plate 301 are larger, and the coal will permeate through the holes on the first screening plate 301 to the second screening plate 302, thereby filtering out most of the impurities. The holes on the second screening plate 302 are smaller, and the coal permeates through the holes on the second screening plate 302 to the transmission plate 303, thereby further filtering out the remaining impurities. At this time, most of the impurities are discharged through the upper discharge port 5, a small part of the impurities are discharged through the middle discharge port 5, and the coal is discharged through the lower discharge port 5, thereby achieving the screening and separation of impurities.

[0030] When the first screening plate 301 and the second screening plate 302 reciprocate up and down, they will drive the connecting rod 318 to move up and down, thereby driving the reset slider 312 to deform the two lower reset springs 313. The reset springs 313 reset after the second motor 304 is turned off. At this time, the first screening plate 301 and the second screening plate 302 will be reset, thereby realizing the adjustment of the position of the first screening plate 301 and the second screening plate 302.

[0031] After the coal impurity separation process is completed, when the first screening plate 301 and the second screening plate 302 need to be cleaned, the first motor 201 is started. The output end of the first motor 201 drives the active connecting rod 202 to rotate. At this time, the active connecting rod 202 drives the driven connecting rod 204 to move through the fixed connecting shaft 203. At this time, one end of the driven connecting rod 204 connected to the sliding block 205 moves along the groove opened on the outside of the outer shell 1. The other end of the driven connecting rod 204 drives the sliding shaft 206 to move back and forth along the groove opened on the inner wall of the outer shell 1, thereby driving the cleaning frame 207 to move back and forth inside the outer shell 1 relative to the bottom of the first screening plate 301, so as to clean the first screening plate 301.

[0032] At the same time, the sliding shaft 206 drives the limiting link 208 to reciprocate, and the limiting link 208 drives the support slider 209 to slide along the groove opened inside the outer shell 1. The support slider 209 drives the pulley 211 below to reciprocate, and the pulley 211 drives the connecting rod 210 to reciprocate. At this time, the connecting rod 210 drives the cleaning frame 207 to reciprocate inside the outer shell 1 relative to the second screening plate 302, thereby cleaning the second screening plate 302.
