[0003] In the prior art, since the position of the feed pipe is fixed, the material from top to bottom will fixedly flush a specific part of the screen, which will not only affect the service life of the screen, but also cause uneven distribution of the material and reduce work efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a vibrating screen to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A vibrating screen includes a tank body, a screen bracket is fixed to the inner wall of the tank body, a screen is arranged on the screen bracket, a vibration motor is installed at the center of the bottom of the screen, and a feed pipe is connected to the top of the tank body. An arc-shaped buffer plate is arranged directly below the feed pipe, and a material guide assembly is arranged directly below the buffer plate. The material guide assembly includes a left rotating shaft, a right rotating shaft, a left material guide plate, a right material guide plate, a driven gear, a driving gear and a servo motor. The left rotating shaft and the right rotating shaft are arranged in parallel and rotated in the tank body. The left rotating shaft is fixedly connected to the left material guide plate, and the right rotating shaft is fixedly connected to the right material guide plate. One end of the left rotating shaft and the right rotating shaft protrude out of the tank body, and a driven gear is arranged at the end of the left rotating shaft, and a driving gear is arranged at the corresponding position of the right rotating shaft. The driven gear and the driving gear are gear-drivenly connected. The end of the right rotating shaft is connected to a servo motor, and the servo motor is used to drive the left material guide plate and the right material guide plate to swing back and forth.

[0007] Furthermore, the reciprocating swing angle range of the left guide plate and the right guide plate is 0 to 60 degrees.

[0008] Furthermore, bearings are provided at both ends of the left rotating shaft and the right rotating shaft.

[0009] Furthermore, the driven gear and the driving gear are arranged in a gear box, and the gear box is fixed on the outside of the tank body.

[0010] Furthermore, a slag discharge port is provided on the side of the tank body, and a discharge pipe and supporting legs are provided at the bottom of the tank body.

[0011] The utility model also includes other components that enable the vibrating screen to be used normally, and these devices or components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the vibration motor, bearing and servo motor in this application. In the specific implementation process, the appropriate device or component model can be selected according to the specific working scene.

[0012] The working principle of the utility model is as follows: an arc-shaped buffer plate is arranged just below the feed pipe to play a buffering role, so as to prevent the upper material from directly scouring the screen and extend the service life of the screen. After passing through the buffer plate, the material slides from both sides of the buffer plate to the left guide plate and the right guide plate. The servo motor drives the left guide plate and the right guide plate to swing back and forth, thereby changing the falling position of the material, making the material distribution more uniform, and avoiding the reduction of work efficiency due to material accumulation.

[0013] Compared with the prior art, the utility model has the following beneficial effects: 1. Extending the service life of the screen: an arc-shaped buffer plate is arranged directly below the feed pipe to play a buffering role and prevent the upper material from directly scouring the screen. 2. The material distribution is more uniform, improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
