Two sets of flaps are symmetrically hinged along the centerline at the upper end of the crusher shell, connecting to the telescopic mechanism. The crushing mechanism is located below the telescopic mechanism, and a funnel is located directly below the crushing mechanism, connected to the water inlet device. A conveying device is located below the funnel. Two sets of filter boxes are symmetrically arranged on both sides of the crusher shell. When the exhaust fan rotates, dust inside the crusher shell is drawn into the filter box housing through a ventilation duct. The filter removes dust particles from the gas, and clean gas is discharged outside the device, thus protecting the environment from pollution. However, this patent still has the following problems in actual use:

[0003] Existing crushers have high crushing efficiency, resulting in a short residence time of crushed stone inside the crusher. Furthermore, due to the continuous production process, dust is constantly and in large quantities generated inside the crusher during discharge. Consequently, the time available for dust removal by the aforementioned devices is limited, resulting in limited dust removal efficiency. Moreover, the aforementioned equipment can only remove dust that is thrown into the air during the moment of stone crushing, but some dust will still be carried away by the crushed stone and leave the equipment, resulting in low dust removal efficiency.

[0004] A dust removal function for ore crushing machine is proposed to solve the problems mentioned above. Utility Model Content

The specific details are as follows:

[0017] 1. By repeatedly inserting the connecting sleeve into the locking sleeve through the extension plate, the upper and lower locking buckles rotate alternately and lock the locking ring that enters the locking sleeve. Finally, the upper and lower partition plates are pulled outward alternately and then pushed back to their original positions. As the crushed stone falls, it is blocked and stopped by the two partition plates, allowing sufficient time for the dust carried by the stone to be extracted. Furthermore, since there is always a partition plate inserted into the discharge channel, the discharge port of the crushing chamber is always isolated from the outside, preventing the dust from being unable to be absorbed in a short time when a large amount of dust is discharged, thus improving the dust extraction efficiency and effect.

[0036] A dust extraction assembly 3 is provided on one side of the bottom of the installation table 1. The dust extraction assembly 3 includes an installation chamber 301, which is fixedly installed on the bottom surface of the installation table 1. A dust collection drawer 302 is inserted into the front of the installation chamber 301. An inclined mesh 303 is fixedly connected inside the dust collection drawer 302. A branched air duct 304 is fixedly connected between the installation chamber 301 and the discharge channel 201. Ventilation openings are provided at the bottom of both the dust collection drawer 302 and the installation chamber 301. An exhaust fan 305 is fixedly installed at the bottom of the installation chamber 301, and the air inlet of the exhaust fan 305 is connected to the ventilation opening. The dust attached to the inclined mesh 303 will move down the inclined surface under the vibration of the crusher during operation, avoiding complete blockage of the inclined mesh 303 before cleaning. The ventilation opening is below the inclined mesh 303. The two branches of the branched air duct 304 are connected to the discharge channel 201 above the partition plate 202.

[0037] Working principle: Before using this type of ore crusher with dust removal function, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7 As shown, firstly, the drive motor 225 is started to make the drive wheel 226 rotate. Then, the connecting column 227 drives the turntable 229 to rotate through the conveyor belt and the driven wheel 228. This causes the pull rod 230 to pull the stud 231 to move horizontally back and forth, which in turn causes the threaded sleeve 236 to rotate. At this time, the control gear 237 drives the linkage gear 234 to rotate, which in turn causes the transmission gear 235 to rotate, which in turn causes the side rack 204 to drive the connecting rod 205 to move back and forth.

[0038] When the connecting rod 205 drives the connecting sleeve 208 to insert into the locking sleeve 207 via the extension plate 206, it will push the locking plate 238 to move and squeeze the first spring 209, thereby causing the locking pin 211 to slide in the limiting groove 212 and lock with the end of the limiting groove 212. During the movement of the locking plate 238, the first rack 213 drives the micro gear 214 to rotate, thereby causing the second rack 215 to drive the ramp block 217 to slide in the side groove 216. The ramp block 217 will first contact the rotating wheel 219 and push it. The rotating wheel 219 moves along the inclined plane, which causes the locking buckle 218 to rotate and lock the locking ring 224 that enters the locking sleeve 207. Finally, when the connecting sleeve 208 moves outward with the extension plate 206, the locking sleeve 207 drives the partition plate 202 to move. When the upper locking ring 224 engages with the locking buckle 218, the lower locking ring 224 separates from the locking buckle 218. Finally, when the upper partition plate 202 moves due to being pulled, the lower partition plate 202 is inserted into the discharge channel 201.

[0039] Similarly, when the lower partition plate 202 can move outward, the upper partition plate 202 is inserted into the discharge channel 201. As the crushed stone falls, it is blocked and stopped by the two partition plates 202, allowing sufficient time for the dust carried by the stone to be extracted. Since there is always a partition plate 202 inserted into the discharge channel 201, the discharge port of the crushing chamber 101 is always blocked from the outside, preventing the dust from being unable to be absorbed in a short time when a large amount of dust is discharged, thus improving the dust extraction efficiency and effect.

[0040] The exhaust fan 305, through the vent and the branch duct 304, can absorb all the dust in the area above the partition plate 202. Moreover, by pulling out the dust collection drawer 302, the dust inside the dust collection drawer 302 can be cleaned.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
