[0025] During use, the material 15 to be screened is lifted to the top of the vibrating screen 8 by the elevator 10, and the material 15 falls onto the vibrating screen 8 through the feed port 9. At the same time, the vibration motor 6 drives the second mounting frame 7 and the vibrating screen 8 to vibrate, so as to realize effective vibration screening of the material 15, and the screening efficiency is high. The transition plate 14 transitions the material 15 that falls through the feed port 9, and the material 15 on the inclined surface at the top of the transition plate 14 slides to the bottom of the vibrating screen 8 for screening under the action of vibration. At the same time, the guide plate 11 separates the material 15 to avoid the accumulation of the material 15 during the vibration screening process, thereby reducing the loss of the material 15 caused by the friction between each other during the vibration process, such as the breakage and damage of the material 15, and in the process of the material 15 sliding off the transition plate 14, the material shifting mechanism 13 shifts the material 15 to ensure that the material 15 can be dispersed and fall between two adjacent guide plates 11, further avoiding the accumulation of the material 15 during the screening process.

[0037] When in use, the material 15 to be screened is lifted to the top of the vibrating screen 8 by the elevator 10, and the material 15 falls onto the vibrating screen 8 through the feed port 9. At the same time, the vibration motor 6 drives the second mounting frame 7 and the vibrating screen 8 to vibrate, thereby realizing effective vibration screening of the material 15, and the screening efficiency is high. The transition plate 14 transitions the material 15 that falls through the feed port 9, and the material 15 on the inclined surface at the top of the transition plate 14 slides to the bottom of the vibrating screen 8 for screening under the action of vibration. At the same time, the guide plate 11 separates the material 15 to avoid the accumulation of the material 15 during the vibration screening process, thereby reducing the loss of the material 15 caused by the friction between the materials 15 during the vibration process, and the material 15 is moved by the material-digging mechanism 13 during the process of sliding off the transition plate 14 to ensure that the material 15 can be dispersed and fall between the two adjacent guide plates 11, thereby further avoiding the accumulation of the material 15 during the screening process; the inclined screen plate 12 is inclined, which increases the contact with the material 15 The contact area improves the screening efficiency, and the guide plate 11 also has the function of guiding the material 15, guiding the material 15 to the side of the inclined screen plate 12, ensuring that the material 15 is in full contact with the inclined screen plate 12; in the process of the vibration motor 6 driving the vibrating screen 8 to vibrate, the counterweight component 136 is lifted and shaken under the action of vibration, its own gravity and the elastic action of the elastic component 137, thereby driving the lifting rod 131 and the material-digging component 132 to lift and shake accordingly, and at this time, the material-digging component 132 vertically digs the material 15 sliding off the transition plate 14, so that the material 15 is dispersed and slides; when the lifting rod 131 moves up and down with the counterweight component 136, the slider 134 slides inside the guide groove 133 and guides the lifting and lowering of the lifting rod 131, so that the lifting rod 131 also rotates during the vertical lifting process, thereby driving the material-digging component 132 to move up and down and also rotate, and digs the material 15 in the vertical and horizontal directions at the same time, ensuring the effective dispersion of the material 15.
