[0025] As shown in the accompanying Figure 1 to the accompanying Figure 8 , the speed-adjustable vibration platform is composed of a material tray 1, a transmission component 2 and a base 3. The base 3 serves as a support foundation, and the left support plate 25 and the right support plate 26 are fixed perpendicularly to the base on both sides through bolts, forming a symmetrical support structure. The left guide mechanism 21 and the right guide mechanism 22 are fixed on the left support plate 25 and the right support plate 26 respectively through screws on the support 213, and the sliding block 212 is internally provided with a high-precision linear bearing, which can slide linearly along the guide rail 211 to provide lateral guidance for the vibration platform. The left guide mechanism 21 and the right guide mechanism 22 are identical in structure and consistent in assembly method, ensuring that the guide precision on both sides is symmetrical. The sliding block 212 has four screw holes, and the bottom of the material tray 1 is processed with mounting holes matched with the sliding block, and the sliding block and the material tray 1 are connected and fixed through screws.

[0026] The motor seat of the reciprocating telescopic mechanism 23 is provided with a screw hole, and is fixed in the middle of the base 3 through a screw. The motor 238 is an adjustable speed AC servo motor, one end of the crank 237 is connected with the motor output shaft, and the other end is hinged with the connecting rod 236 through a pin shaft, and the other end of the connecting rod is hinged with the front end of the telescopic rod 235, forming a crank block transmission mechanism. The telescopic rod 235 is a cylindrical metal rod, and a linear bearing 234 is sleeved on the outside, which is fixed on the outside of the motor seat, ensuring that the telescopic rod makes strict linear reciprocating motion. The telescopic rod is processed with external threads at the end, and the left locking nut 232 and the right locking nut 233 lock and fix the L-shaped angle iron 240 through threaded connection. The bottom of the material tray 1 is processed with mounting holes matched with the vertical section of the L-shaped angle iron, and the material tray locking screw 239 is fastened and connected with the L-shaped angle iron through the mounting holes, forming a vibration table surface, and the material tray vibrates synchronously with the telescopic rod.

[0027] The speed regulating device 24 is fixed on the side of the left supporting plate 25 by screws, the plug 244 is a standard power interface, used for connecting an external power source, the motor connecting wire 241 is connected with the motor, the switch 242 controls the start and stop of the motor, and the speed regulating knob 243 can continuously adjust the rotating speed of the motor, so that the reciprocating motion frequency of the telescopic rod is changed, the vibration speed of the material disc is accurately controlled, the motor 238 is powered on, the crank 237 is driven to make a circular motion, the linear reciprocating motion of the telescopic rod 235 is converted from the rotating motion through the connecting rod 236, the L-shaped angle iron 240 and the material disc 1 are driven to reciprocate along the guide rail of the guide mechanism, the material disc is vibrated, and the caked material is scattered.

[0028] A specific application of the embodiment is that the vibration and scattering process of powdery material in the chemical industry is taken as an example: in use, an operator first places the caked powdery material to be scattered on the material disc 1, then connects the plug 244 to an external power source, turns on the switch 242, and adjusts the speed regulating knob 243 according to the material characteristics (such as particle size and viscosity). At this time, the motor 238 is powered on, the crank 237 is driven to make a circular motion, the linear reciprocating motion of the telescopic rod 235 is converted from the rotating motion through the connecting rod 236, the L-shaped angle iron 240 and the material disc 1 are driven to reciprocate along the guide rail of the guide mechanism, the material disc is vibrated, and the caked material is scattered. During the vibration process, the guide rail 211 and the sliding block 212 ensure that the vibration table is stable and has no deviation, and the linear bearing further improves the motion accuracy. After the material is scattered, the operator turns off the switch, removes and takes out the uniformly dispersed material, the material enters a subsequent processing procedure, and the operation is completed.
