[0024] The specific use scenario of this embodiment is: The load adjustment component is provided to adjust the load on the top of the vibrating screen 133. The vibration component is provided to install and test the anti-fatigue and anti-tearing performance of the vibrating screen 133 during vibration, which is convenient for testing the service life of the vibrating screen 133.

[0025] Embodiment 2: As Figure 3 andFigure 5 Between the base 100 and the vibrating bowl 130, they are movably connected through the movable plate 140. The two ends of the movable plate 140 are connected to the ear hooks 120 on the outer walls of the base 100 and the vibrating bowl 130 in a matching manner. The three-section flat plate of the movable plate 140 is a sequentially rotating structure through hinges. The driving shafts 150 are rotatably connected to the inner walls of both the base 100 and the vibrating bowl 130. An eccentric wheel 160 is fixedly installed on the outer wall of the driving shaft 150 at the inner wall of the base 100. The outer wall of the eccentric wheel 160 and the outer wall of the driving shaft 150 at the outer wall of the vibrating bowl 130 are rotatably connected through a connecting rod 170. A first servo motor 180 is fixedly installed on the outer wall of the base 100 at the end far from the connecting rod 170. The outer wall of the output shaft of the first servo motor 180 and the outer wall of the driving shaft 150 are in transmission connection through a pulley 181 and a belt 182.

By driving the second servo motor 230, the second servo motor 230 drives the bevel gear 231 to drive the rotating shaft 222 to rotate, so that the rotating shaft 222 controls the release of the traction rope 224. Under the action of the traction rope 224, the counterweight 225 is released to the top of the vibrating screen 133, thereby adjusting the load on the top of the vibrating screen 133. Subsequently, by turning on the first servo motor 180, the first servo motor 180 can drive the eccentric wheel 160 and the connecting rod 170 to rotate, so that the first servo motor 180 can pull the vibrating screen 133 to perform reciprocating up and down movements. Under the action of the movable block 140, the vibrating screen 133 is driven to perform reciprocating deflection movements, thereby checking the load-bearing performance, anti-fatigue strength and service life of the vibrating screen 133.
