[0031] A movable frame 106 is slidably connected to the center of the movable frame 103. The left and right sides of the movable frame 106 are fixedly connected to dual-axis motors 107. The output ends of the two dual-axis motors 107 pass through the movable frame 106 and are fixedly connected to counterweights 108. The counterweights 108 are rotated by the dual-axis motors 107.

[0032] The movable frame 106 has a second spring post 109 inside both ends. The upper and lower ends of the second spring post 109 are fixedly connected to the movable frame 103. The top two ends of the movable frame 106 are fixedly connected to the support post 110. By setting the spring compression of the first spring post 104 and the second spring post 109, a part of the vibration force can be absorbed to achieve the effect of noise reduction.

[0033] The top of the support column 110 passes through the movable frame 103 and is fixedly connected to the top plate 111. The top of the top plate 111 is fixedly connected to the vibrating frame 112. One end of the vibrating frame 112 is fixedly connected to the discharge hopper 113. A screening frame 114 is set below the discharge hopper 113. The movable frame 106 drives the vibrating frame 112 to vibrate, and at the same time disperses and transports the ore in the vibrating frame 112 to the discharge hopper 113.

[0034] One side of the screening frame 114 is fixedly connected to the drive motor 115. The output end of the drive motor 115 passes through the screening frame 114 and is fixedly connected to the first roller shaft 116. One end of the first roller shaft 116 passes through the screening frame 114 and is attached to the belt 117.

[0037] Working principle: Before using this type of ore crushing device with a screening structure, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6 As shown, the ore is first poured into the crushing chamber 201 from the hopper 202. Then, the servo motor 203 is started to drive the rotating shaft 204 to rotate. The rotating shaft 204 drives the cutter holder 206 and the guide plate 205 to rotate quickly, which can guide the ore and crush it with the crushing blade 207, thereby achieving the purpose of ore crushing.

[0038] Secondly, the crushed ore falls onto the surface of the vibrating frame 112, and then the dual-axis motor 107 is started to drive the counterweight 108 to rotate. The simultaneous operation of the eight counterweights 108 can drive the movable frame 106 to move up, down, left and right. At the same time, the compression of the springs of the first spring column 104 and the second spring column 109 can absorb some of the vibration force, thereby achieving the effect of noise reduction. The movable frame 106 drives the vibrating frame 112 to vibrate, and at the same time, the ore in the vibrating frame 112 is dispersed and transported to the discharge hopper 113.

[0039] Finally, the drive motor 115 is started to drive the first roller 116 to rotate. With the synchronous action of the belt 117, the second roller 118 can be driven to rotate simultaneously with the first roller 116. By making the angle between the first roller 116 and the second roller 118 increasingly larger, different sizes of ore can be screened and stored.
