[0027] See also Figure 2 A trigger guide groove is provided on the upper wall of the adjustment guide frame 3. When in use, the trigger motor 5 drives the trigger switch 7 through the transmission shaft 6 to rotate one circle along the trigger guide groove provided on the upper wall of the adjustment guide frame 3, driving the auxiliary filter plate 8 on the object identifier to move downward along the auxiliary guide groove 4.

[0028] See also Figure 4 The induced draft frame 16 is equipped with an induced draft sleeve 25. When in use, the dust removal fan blade 1 is started, and the dust removal fan blade 1 guides the air inside the coal mine outward along the induced draft sleeve 25.

[0030] Example 1. In this embodiment, through the linkage of four air-inducing telescopic bars 19 and the dust-removing telescopic bar 9, in cooperation with two locking springs 12, two locking balls 13 are driven to extend and retract along two spring guide grooves 11, and the auxiliary filter plate 8 is fixed in front of the dust-removing blades 1, thereby realizing automatic replacement of the auxiliary filter plate 8 in front of the dust-removing blades 1.

[0031] The auxiliary filter plate 8 at the outermost end of the feeding chute 17 falls into the auxiliary guide groove 4 and is supported by the auxiliary filter plate 8 stuck on the two locking balls 13. At this time, the dust removal fan blade 1 is started, and the dust removal fan blade 1 blows the air inside the coal mine along the induced draft sleeve 25. After the dust is discharged outwards, after a certain period of time, the auxiliary filter plate 8 in front of the dust removal fan blade 1 is full of dust, the trigger motor 5 drives the trigger switch 7 to rotate one circle along the trigger guide groove opened on the upper wall of the adjusting guide frame 3 through the transmission shaft 6, driving the auxiliary filter plate 8 on the object identifier to move downwards along the auxiliary guide groove 4, squeezing the auxiliary filter plate 8 in front of the dust removal fan blade 1 from the two locking balls 13, and then falling in front of the dust removal pushing block 10 along the guide groove 4.

At this time, the auxiliary filter plate 8 above the auxiliary guide groove 4 falls, passes the two locking balls 13, and the two locking balls 13 slide along the guide groove 14 into the limit slot 15, locking the auxiliary filter plate 8. The object identifier in the auxiliary guide groove 4 detects again that there is no auxiliary filter plate 8 above the auxiliary guide groove 4, and the four air-inducing telescopic rods 19 are started again, and then the cycle is repeated in the above manner.

[0032] Example 2. In this embodiment, the loading cover 22 is held and rotated around the auxiliary rotating shaft 21, and then the four induced draft telescopic bars 19 are started to drive the induced draft push block 20 to contract to achieve loading, and the material removal plate 24 is held to drive several auxiliary filter plates 8 filled with dust to be pulled out along the material removal trough 18 through the two sliders 23 to achieve material removal.

[0033] Specifically, when loading, the operator holds the loading cover 22 and rotates it around the auxiliary rotating shaft 21, and then starts the four induced draft telescopic bars 19 to drive the induced draft push block 20 to retract. At this time, the operator puts several auxiliary filter plates 8 into the loading trough 17, and finally resets the loading cover 22. When taking out materials, the operator takes out the induced draft sleeve 25 along the induced draft frame 16, and then holds the taking out plate 24 to drive the several auxiliary filter plates 8 covered with dust to be pulled out along the taking out trough 18 through the two slide blocks 23. After sorting, the taking out plate 24 and the induced draft sleeve 25 are reset.
