[0020] Furthermore, under the action of the servo motor 4, the fixed rod 8 forms a limited sliding structure with the fixed frame 3 through the screw 5, the sliding rod 6, the movable block 7, and the brush 11 is inserted into the limiting hole through the L-shaped locking rod 9 and the elastic limiting block 10 to form a locking limiting structure with the fixed rod 8, so that after the vibration screen 1 is completed, the brush 11 can be locked and installed on the fixed rod 8 through the elastic limiting block 10, so that the servo motor 4 can drive the brush 11 to clean the dust and other impurities remaining on the screen 2.
[0021] Support plates 12 are provided on the inner walls of both sides of the vibrating screen 1 below the screen 2, and a first fixing plate 16 is placed on the support plate 12, and a plurality of groups of protrusions are provided on the first fixing plate 16. Two groups of electric push rods 13 are provided inside the vibrating screen 1, and a telescopic arm 14 is provided on the upper part of the electric push rod 13, and a push plate 15 is provided at the other end of the telescopic arm 14.
[0022] Furthermore, under the action of the electric push rod 13, the first fixed plate 16 forms a lifting structure with the screen 2 through the telescopic arm 14, so that the inner side of the first fixed plate 16 is lifted and lowered by the electric push rod 13, and the material engaged in the screen 2 is processed by the protrusion on the first fixed plate 16.
[0023] The vibrating screen 1 is provided with a feed port at the top, and a discharge port at the other end, a second fixed plate 17 is provided on the vibrating screen 1 above the discharge port, and a rotating rod 18 is inserted at the front end of the second fixed plate 17, and a baffle 19 is provided on the outer wall of the rotating rod 18, and a collecting box is placed under the baffle 19. It should be additionally explained that a hollow plate is provided on the outer side of the screen 2, and the diameter of the through holes on the hollow plate is larger than the mesh of the screen 2, thereby ensuring that the screened material can fall into the collecting box through the hollow plate.
[0024] Furthermore, the baffle 19 forms a rotating structure with the second fixed plate 17 through the rotating rod 18, so that the baffle 19 can prevent the screened materials from splashing during the unloading process.
[0025] Working principle: When using the new type of multi-frequency vibrating screen, first put the material into the vibrating screen 1 through the feed port, and screen the material through the vibrating mesh screen 2. After screening, the larger material moves from the screen 2 to the hollow plate at the discharge port, so that the material can fall into the collection box through the hollow plate for collection. At the same time, the material can be blocked by the baffle 19 to prevent some materials from rolling down at a faster speed and splashing. If a lot of material is accumulated at the junction of the hollow plate and the baffle 19, the baffle 19 can be rotated by the rotating rod 18 to avoid affecting the discharge efficiency of the vibrating screen 1; after the vibrating screen 1 is completed, the first fixed plate 16 can be placed on the support plate 12, and the first fixed plate 16 can be pushed upward. At the same time, the electric push rod inside the vibrating screen 1 13 drives the push plate 15 to rise through the telescopic arm 14, thereby ensuring that the first fixed plate 16 can move as a whole, so that the material engaged on the screen 2 can be processed through the protrusions on the first fixed plate 16; when the screen 2 is dredged, the first fixed plate 16 can be taken out, and then the elastic limit block 10 on the L-shaped engaging rod 9 can be pressed, so that the brush 11 can be engaged and installed on the fixing rod 8. When the brush 11 is installed, the servo motor 4 can be started, and the output shaft of the servo motor 4 drives the screw 5 to rotate through the coupling, and drives the brush 11 through the sliding rod 6 and the movable block 7 to comprehensively clean the screen 2, thereby preventing residual materials or impurities on the screen 2 from affecting the subsequent work of the vibrating screen 1. This is the use process of the new multi-frequency vibrating screen.
