[0019] The ore after preliminary dust removal falls onto the conveyor belt through the drop pipe, and the suction fan blows air into the collection box. The exhaust fan draws the dust out of the collection box and the dust box, and the dust in the ash inlet pipe is drawn onto the outer filter plate. The outer filter plate only allows air to pass through. The dust extracted by the ash inlet pipe falls from the bottom of the dust box.

[0051] The outer filter plate 331 may be blocked by the cleaning motor 320, and the output gear 321 may be driven to rotate, thereby driving the transmission gear 322 and the screw wheel 323 to rotate, and the transmission belt 325 drives the other screw wheel 323 to rotate, thereby driving the two bidirectional screws 326 to rotate at the same time, thereby driving the internal threaded sleeve 330 to slide up and down, thereby driving the cleaning wheel 328 to slide up and down, and at the same time, the cleaning wheel 328 drives the cleaning gear 329 to move together, and under the action of the fixed rack 327, the cleaning wheel 328 and the cleaning gear 329 are driven to rotate relative to the internal threaded sleeve 330, so that the cleaning wheel 328 can be raised and lowered and rotated at the same time, and the surface of the outer filter plate 331 is cleaned by the cleaning wheel 328, and the dust attached to the outer filter plate 331 is brushed off and discharged from the lower part of the dust collecting box 302.

[0052] The working principle of a mining crushing device with a dust collection function disclosed in the present invention is: adjusting the extension and retraction of the electric cylinder 111 drives the rotating slot rod 114 to rotate around the crushing box 101, thereby driving the two sliding rods 112 to move inward or outward at the same time through the slide groove and the rotating sleeve 113 on the rotating slot rod 114, thereby driving the upper crushing plate 116 and the lower crushing plate 118 to move inward or outward at the same time, thereby adjusting the positions of the upper crushing plate 116 and the lower crushing plate 118. The rotation of the crushing motor 102 drives the motor bevel gear 103 to rotate, which drives the docking shaft 104 and the driving wheel 106 to rotate through the docking bevel gear 105, drives the upper transmission wheel 108 to rotate through the upper transmission belt 107, drives the lower transmission wheel 110 to rotate through the lower transmission belt 109, and the upper transmission wheel 108 and the lower transmission wheel 110 respectively drive the two eccentric wheels 121 to rotate, thereby driving the upper jaw plate 115 and the lower jaw plate 117 to rotate eccentrically through the eccentric wheel 121, and under the action of the upper connecting rod 119 and the lower connecting rod 120, the upper jaw plate 115 and the lower jaw plate 117 swing continuously. The ore to be crushed is put in from the top of the crushing box 101, and the ore first reaches between the upper crushing plate 116 and the upper jaw plate 115, and the ore is initially crushed by the back and forth swing of the upper jaw plate 115 in cooperation with the upper crushing plate 116. Then the ore reaches between the lower jaw plate 117 and the lower crushing plate 118, and the ore is further crushed by the swing of the lower jaw plate 117 in cooperation with the lower crushing plate 118. After the crushing, the ore falls into the sootblower 201. The crushed ore falls onto the stone-throwing plate 206, and the rotation of the central shaft 208 drives the fan blades 210 and the stone-throwing plate 206 to rotate. The fan blades 210 rotate to blow air outward through the ventilation grooves of the isolation tube 205, and the ore on the stone-throwing plate 206 slides to between the soot blowing tube 201 and the isolation tube 205 through the conical inclined surface of the stone-throwing plate 206. The rotation of the stone-throwing plate 206 provides centrifugal force and cooperates with the blowing of the fan blades 210 to throw the dust generated by the ore crushing into the ash outlet hole 207. The dust enters the ash extraction ring 203 through the ash outlet hole 207 and is finally extracted by the exhaust fan 319 through the ash inlet pipe 204. The rotation of the central shaft 208 will also drive the scraper 213 to move through the extension rod 212, and the ore located between the soot blowing tube 201 and the isolation tube 205 is pushed into the drop tube 304 through the scraper 213.After preliminary dust removal, the ore falls onto the conveyor belt 307 through the drop pipe 304, and the suction fan 303 blows air into the collection box 301. The exhaust fan 319 extracts the dust in the collection box 301 and the dust box 302 outward, and the dust in the ash inlet pipe 204 is sucked onto the outer filter plate 331. The outer filter plate 331 only allows air to pass through. The dust extracted by the ash inlet pipe 204 falls from the bottom of the dust box 302. At the same time, the exhaust fan 319 extracts the dust remaining on the ore that falls into the drop pipe 304 and the conveyor belt 307 onto the outer filter plate 331. Then the dust is removed from the collection box 301 and the dust box 302 is removed. The ore falls from the bottom of the dust box 302, and the inner filter 318 is used to block the ore. The bottom motor 309 rotates to drive the motor gear 310 to rotate, thereby driving the lower bevel gear 209 and the center shaft 208 to rotate, thereby driving the inner bevel gear 311 and the outer bevel gear 312 to rotate, driving the docking gear 314, the gear shaft 313 and the driving wheel 315 to rotate, and driving the driven wheel 317 and the conveying wheel 306 to rotate through the inclined transmission belt 316, and the dust-removed ore is transported to the discharge slope 305 through the conveyor belt 307 and the push plate 308, and the ore falls out from the discharge slope 305.
