Spring 251, and two groups of arc shafts 270 are fixedly connected to one side of the receiving plate 260, a round hole 272 matching the arc shaft 270 is opened on one side of the fixed plate 240, a clamping rod 280 slidably connected to the inside of the fixed plate 240 is provided on one side of the round hole 272, and a spring a290 is sleeved on the surface of the clamping rod 280, an arc screen 2910 is attached to the bottom end of the receiving plate 260, an arc plate 2920 is provided on one side of the arc screen 2910, and two groups of flip bars 2940 are welded on the side of the arc plate 2920 away from the arc screen 2910; The screening assembly 300 includes multiple groups of springs b330 welded to one side of the fixed plate 240, and a square block 320 is provided on the side of the multiple groups of springs b330 away from the fixed plate 240. A circular shaft 310 is fixedly connected inside the square block 320, and a knocking block 340 that fits the fixed plate 240 is welded to the bottom end of the square block 320. Several groups of fixed blocks 350 are welded to one side of the receiving plate 260, and spring telescopic rods 360 are fixedly connected at both ends of the circular shaft 310. The movable rod ends of the spring telescopic rods 360 are fixedly connected to inclined blocks 370. Arc guide rails 390 are slidably connected to both sides of the surface of the circular shaft 310, and several groups of trapezoidal blocks 380 are fixedly connected to the outer walls of the arc guide rails 390.

[0020] The ore fragments crushed by the crushing roller 120 will fall onto the surface of the arc screen 2910. The arc screen 2910 can separate the crushed ore according to the particle size, so that qualified finished products can be separated in time, thereby improving the screening efficiency. At this time, the rotating motor 210 is started to drive the rotating disk 220 to rotate, and the rotating disk 220 drives the long shaft 230 to rotate synchronously, so that the long shaft 230 drives the fixed plate 240 to move in an arc, and the fixed plate 240 drives the receiving plate 260 to fit The receiving plate 260 moves synchronously with the arc screen 2910, and the ore fragments that have not fallen from the surface of the arc screen 2910 are received by the receiving plate 260, so that the ore is moved to the surface of the receiving plate 260. The continuous arc movement of the receiving plate 260 drives the synchronous transportation of the ore. When the receiving plate 260 rotates to 220 degrees, the receiving plate 260 will be inverted at this time. Under the action of gravity, the ore on the receiving plate 260 will fall from the top of the crushing roller 120, thereby achieving the effect of secondary crushing. The crusher 100 can perform secondary crushing on the ore fragments that do not meet the size, thereby enhancing the adaptability of the equipment and improving the overall crushing efficiency. At the same time, the crushed ore is separated by the arc screen 2910, which can effectively prevent the ore that does not meet the specifications from being mixed in the ore that meets the specifications, further improving the overall quality of the crushed ore.

When passing through a group of trapezoidal blocks 380, the knocking block 340 is reset under the action of the spring b330 and knocks on one side of the fixed plate 240, so that the fixed plate 240 and the receiving plate 260 vibrate. Through multiple groups of trapezoidal blocks 380, it is indirectly and continuously vibrated, which can effectively make the ore fragments that meet the specifications on the receiving plate 260 fall off, further improving the screening effect of the ore. When the receiving plate 260 continues to rotate, it will fit the surface of the flip bar 2940. Under the action of the flip bar 2940, the receiving plate 260 will rotate through the rotating shaft 250, so that the receiving plate 260 drives the arc shaft 270 to move synchronously. When the arc shaft 270 is inserted into the round hole 272, it will squeeze the end of the clamping rod 280. The clamping rod 280 will compress the spring a290 until the clamping rod 280 is embedded in the limiting groove 271 to fix the receiving plate 260. At this time, the rotating motor 210 reverses to reset the receiving plate 260. By fitting the arc screen 2910 with multiple groups of fixing blocks 350, the crushed ore fragments can be effectively broken up, and the fallen fragments can be effectively prevented from accumulating, so that the ore fragments can pass through the arc screen 2910 more easily, thereby improving the screening speed and efficiency. When the receiving plate 260 is reset, the insert rod 281 will be inserted into the arc groove 282, so that the clamping rod 280 releases the limit on the arc shaft 270, and then the receiving plate 260 is reset under the seating of the torsion spring 251, which is convenient for continuous operation and further improves the applicability of the device.

[0029] When in use, the ore for mica sheet processing is added into the crusher 100 from the feed port 111, and the servo motor 110 is started to drive the crushing roller 120 to rotate. The crushing roller 120 drives the gear a130 to rotate synchronously. The gear a130 drives another set of crushing rollers 120 to rotate through the gear b140, so that the two sets of crushing rollers 120 rotate relative to each other, thereby achieving the effect of crushing the ore. The ore fragments crushed by the crushing roller 120 will fall onto the surface of the arc screen 2910. The arc screen 2910 can separate the crushed ore according to the particle size, so that the qualified finished product materials can be separated in time, thereby improving the screening efficiency.
