[0012] 1. In this utility model, through the installation of crushing rollers, crushing shafts are fixedly connected to the middle of both sides of the transmission tube. Crushing rollers are rotatably connected to the crushing shafts. A micro vibrator is fixedly connected to the middle of the crushing shafts. As the rotating shafts rotate, the transmission tubes also drive the crushing shafts and the crushing rollers on them to rotate.

[0014] 3. In this utility model, through the setting of the transmission tube, the lower end of the rotating shaft extends out of the lower end of the crushing roller and is connected to the transmission tube. Since the upper end of the rotating shaft is provided with an annular limiting piece and a rectangular limiting portion, and there is a corresponding rectangular limiting groove inside the transmission tube, this ensures that the rotating shaft can stably pass through the transmission tube during rotation and drive the transmission tube and the components thereon to rotate together.

[0023] Further, the annular limiting sheet 201 is fixedly connected on rotating shaft 2 upper end in transmission pipe 3, the rectangular limiting part 202 is fixedly connected on rotating shaft 2 both sides in annular limiting sheet 201 lower end.

[0024] Further, the rectangular limiting groove 301 is arranged in transmission pipe 3 both sides, rotating shaft 2 is extended to lower end by passing through transmission pipe 3 and makes rectangular limiting part 202 be placed in rectangular limiting groove 301 inside, rotating shaft 2 can stably pass through transmission pipe 3 in the process of rotation, and drive transmission pipe 3 and the components on it rotate together.

[0025] Further, the rotating shaft 2 lower end is inserted into the upper end middle part of circular support 104.

[0026] Further, the middle part of the crushing roller 303 is provided with an annular limiting groove 304, and the micro vibrator 305 in the middle part of the crushing shaft 302 is arranged in the annular limiting groove 304. The micro vibrator 305 in the middle part of the crushing shaft 302 generates slight vibration in operation, which is transmitted to the screen 103 through the crushing roller 303, helps the granulation powder pass through the screen 103 faster, and improves the screening efficiency.

[0027] Further, the upper end surface of the vibrating screen device 1 is fixedly connected with a motor box 4, and the motor box 4 is fixedly provided with a motor 401.

[0028] Further, the upper end of the rotating shaft 2 extends through the upper end surface of the vibrating screen device 1 to the inside of the motor box 4 and is connected with the output shaft of the motor 401 through a shaft coupling. When the motor 401 in the motor box 4 is started, the rotating shaft 2 is driven to rotate through the shaft coupling.

[0029] Working principle: when in use, the coffee-colored aluminum oxide ceramic granulation powder is added into the vibrating screen device 1 through the feeding pipe 101. At this time, the motor 401 in the motor box 4 is started, and the rotating shaft 2 is driven to rotate through the shaft coupling. Since the upper end of the rotating shaft 2 is provided with the annular limiting piece 201 and the rectangular limiting part 202, and the transmission pipe 3 is provided with the corresponding rectangular limiting groove 301, it is ensured that the rotating shaft 2 can stably pass through the transmission pipe 3 during rotation and drive the transmission pipe 3 and the components thereon to rotate together. With the rotation of the rotating shaft 2, the crushing roller 203 and the crushing rod 204 thereon also start to rotate, preliminarily crushing and scattering the granulation powder, making the particles more uniform and reducing the influence of large particles on the subsequent screening process. Then, the preliminarily crushed granulation powder falls onto the screen 103. At this time, since the rotating shaft 2 continues to rotate, the transmission pipe 3 also drives the crushing shaft 302 and the crushing roller 303 thereon to rotate. The crushing roller 303 further crushes and refines the granulation powder on the screen 103, so that it is easier to pass through the screen hole of the screen 103. At the same time, the micro vibrator 305 in the middle part of the crushing shaft 302 generates slight vibration in operation, which is transmitted to the screen 103 through the crushing roller 303, helps the granulation powder pass through the screen 103 faster, and improves the screening efficiency. Finally, the granulation powder after screening and refinement falls through the screen hole of the screen 103 to the bottom of the vibrating screen device 1, and then is discharged through the discharge pipe 102 for subsequent production use.
