[0021] Please refer to Figure 1 , Figure 3 Material guiding mechanism 5 includes guide bucket 51, and the inside of frame 1 is hinged with guide bucket 51, the inside fixed connection of frame 1 has sliding cylinder 52, the inside sliding connection of sliding cylinder 52 has sliding rod 53, the inside of sliding cylinder 52 is provided with spring 54, one end of spring 54 is fixedly connected with frame 1, the other end of spring 54 is fixedly connected with sliding rod 53, by setting spring 54, make sliding rod 53 reset, the end fixed connection of sliding rod 53 has top ball 55, and top ball 55 is in contact with guide bucket 51, by spring 54 acting on sliding rod 53, make top ball 55 elastically support guide bucket 51, further make guide bucket 51 elastically deflect after being impacted by ore, and the feed of ore is guided and buffered, avoid that ore directly impacts sieve plate 4 and leads to sieve plate 4 damage.

[0022] Please see Figure 2 , Figure 4 The vibration mechanism 7 includes a support plate 71, which is fixedly connected inside the frame 1. A motor 72 is fixedly mounted on the lower end of the support plate 71. The shaft of the motor 72 passes through the support plate 71 and is rotatably connected to it. An eccentric wheel 73 is fixedly connected to the upper end of the motor 72 shaft. A top block 74 is slidably connected inside the eccentric wheel 73. The eccentric wheel 73 contacts the frame 1, and the top block 74 is slidably connected to the frame 1. A sliding pin 75 is fixedly connected to the surface of the top block 74, and the sliding pin 75 is slidably connected to the eccentric wheel 73. By setting the sliding pin 75, the movement of the top block 74 is controlled. The eccentric wheel 73 is equipped with a compression spring 76 inside. One end of the compression spring 76 is fixedly connected to the eccentric wheel 73, and the other end of the compression spring 76 is fixedly connected to the top block 74. By setting the compression spring 76, the top block 74 can be easily reset. The frame 1 is fixedly connected to the inside of the inclined plate 77. The eccentric wheel 73 is driven to rotate by the motor 72, so that the top block 74 can automatically extend and retract inside the eccentric wheel 73, driving the support 2 to move back and forth. At the same time, the support 2 and the inclined plate 77 collide and vibrate up and down, so that the ore vibration screening amplitude is larger and the ore screening efficiency is higher.

[0023] The specific implementation process of this utility model is as follows: In use, the motor 72 is started, and the motor 72 drives the eccentric wheel 73 to rotate. The rotation of the eccentric wheel 73 causes the top block 74 to deflect and disengage from the frame 1, thereby causing the compression spring 76 to reset. This causes the top block 74 to automatically extend from the eccentric wheel 73 and collide with the bracket 2, causing the bracket 2 to move back and forth and sway. When the bracket 2 contacts the inclined plate 77, the bracket 2 moves upward. When the bracket 2 slides to the point of disengagement from the inclined plate 77, the bracket 2 moves downward. The motor 72 drives the eccentric wheel 73 to rotate, thereby allowing the top block 74 to automatically extend and retract within the eccentric wheel 73, causing the bracket 2 to move back and forth. Meanwhile, the collision and up-and-down vibration of the support 2 and the inclined plate 77 make the ore vibration screening amplitude larger, resulting in higher ore screening efficiency. When the ore is poured into the frame 1, the ore comes into contact with the guide bucket 51, causing the guide bucket 51 to guide the ore to fall onto the screen plate 4. At the same time, the screen plate 4 is deflected by the force and squeezes the top ball 55, causing the slide rod 53 to slide into the slide cylinder 52. Through the action of the spring 54 on the slide rod 53, the top ball 55 provides elastic support to the guide bucket 51, thereby causing the guide bucket 51 to deflect elastically after being hit by the ore, guiding and buffering the ore feed, and preventing the ore from directly hitting the screen plate 4 and causing damage to the screen plate 4.
