An installation plate 53 is rotatably connected to the arc surface of the screw rod 52. The installation plate 53 is fixedly connected to the surface of the vibrating screen body 1. The effects achieved by the above components are as follows: When using the vibrating screen body 1 to perform screening treatment on materials, first start the vibrating screen body 1 to make it operate, and then start the servo motor 51 on one side of the vibrating screen body 1. The rotation of the servo motor 51 will cause the screw rod 52 to rotate. Due to the sliding limit effect of the limiting plate on the push plate 54, the push plate 54 makes a reciprocating motion driven by the screw rod 52. At this time, pour the materials onto the sieve mesh 3 on the topmost layer of the vibrating screen body 1, and make the push plate 54 push and spread the materials. At this time, when using the vibrating screen body 1 to screen materials, the materials can be poured onto the sieve mesh 3 of the vibrating screen body 1 more evenly, and it is not easy to have excessive accumulation, and the materials can be vibrated and screened more quickly, further improving the working efficiency and use effect of the vibrating screen body 1.

[0030] Referring to Figure 1 、 Figure 2 and Figure 3As shown in the figure, in this embodiment: A bearing 57 is fixedly connected to the arc surface of the screw rod 52. The inner ring of the bearing 57 is fixedly connected to the screw rod 52, and the outer ring of the bearing 57 is fixedly connected to the mounting plate 53. The effect achieved by the above components is that through the setting of the bearing 57, when the screw rod 52 rotates, the friction damage between the screw rod 52 and the mounting plate 53 is reduced, so that the screw rod 52 is not easily damaged, thus ensuring the normal use of the auxiliary device 5. A protective sleeve 58 is sleeved on the arc surface of the output end of the servo motor 51, and the protective sleeve 58 is fixedly connected to the surface of the servo motor 51. The effect achieved by the above components is that through the setting of the protective sleeve 58, during the use of the servo motor 51, it can remain normal, and it is not easy for debris and impurities of the material to enter the inside of the servo motor 51 and cause erosion and damage to its components, ensuring the normal use of the servo motor 51.

The effect achieved by the above components is that when the material is poured onto the vibrating screen body 1 for screening, first pour the material into the hopper 62 above the vibrating screen body 1, and then start the electric telescopic rod 63. The baffle 64 moves and rises under the drive of the electric telescopic rod 63, so that the outlet below the hopper 62 is opened, and the material is poured into the screen 3 of the uppermost screen frame 2 of the vibrating screen body 1. At this time, when the material is poured into the vibrating screen body 1, it can be more uniform, not too much or too little, which affects the working efficiency of the vibrating screen body 1, and it is more convenient for the auxiliary device 5 to spread and evenly distribute the material on the screen 3, improving the use effect of the vibrating screen body 1.

[0034] Working principle: When using the vibrating screen body 1 to screen materials, first start the vibrating screen body 1 to make it operate, and then start the servo motor 51 on one side of the vibrating screen body 1. The rotation of the servo motor 51 will cause the screw 52 to rotate. Due to the sliding limit effect of the limit plate on the push plate 54, the push plate 54 makes a reciprocating motion driven by the screw 52. At this time, the material is poured onto the topmost screen 3 of the vibrating screen body 1, and the push plate 54 is used to push and spread the material. When using the vibrating screen body 1 to screen materials, the material can be poured more evenly onto the screen 3 of the vibrating screen body 1, and it is not easy to accumulate excessively, and the material can be vibrated and screened more quickly, further improving the working efficiency and use effect of the vibrating screen body 1.

[0035] When pouring the material onto the vibrating screen body 1 for screening, first pour the material into the hopper 62 above the vibrating screen body 1, and then start the electric telescopic rod 63. The baffle 64 moves and rises driven by the electric telescopic rod 63, so that the outlet below the hopper 62 is opened, and the material is poured into the screen 3 of the uppermost screen frame 2 of the vibrating screen body 1. At this time, when the material is poured into the vibrating screen body 1, it can be more uniform, not too much or too little, which will not affect the working efficiency of the vibrating screen body 1, and it is more convenient for the auxiliary device 5 to spread and evenly divide the material on the screen 3, improving the use effect of the vibrating screen body 1.
