The ultrasonic piezoelectric ceramic plate 160 is tightly assembled to the screw, and can convert an electric signal input by an ultrasonic control power supply into ultrasonic waves, and the ultrasonic energy is transmitted to the first fixing member 120 by the resonance generated between the screw and the second fixing member 130, so that the ultrasonic energy can be transmitted to the sieve tray 180 assembly assembled with the assembling portion of the second fixing member 130, and the purpose of cleaning materials on the sieve tray 180 is achieved. The ultrasonic piezoelectric ceramic sheet 160 is a functional element which can be directly purchased in the existing market, has a plurality of multi-frequency ultrasonic frequencies, and belongs to a device for radially conducting ultrasonic waves; the radial conduction angle of the ultrasonic piezoelectric ceramic sheet 160 is 360 degrees, so that the sieve tray 180 vibrates 360 degrees in the horizontal direction, and the cleaning dead angle can be avoided.

The periphery of the mounting opening is provided with a convex edge 112, so that an annular groove is formed on the end surface of the mounting opening, and a rubber gasket 113 is arranged between the bottom surface of the first fixing member 120 and the annular groove. The first fixing member 120 can vibrate left and right in the horizontal direction under the action of ultrasonic waves, and the installation structure of the first fixing member 120 and the shell 110 in the left and right direction can be firmer without relative shaking after the annular groove is additionally arranged; in addition, the rubber gasket 113 can play a role in sealing and damping the mounting structure between the first fixing member 120 and the housing 110, so that the ultrasonic vibrator can be ensured to have better sealing performance and lower vibration noise.

The assembling part comprises a connecting nut and a second screw rod 121 arranged at the top of the first fixing part 120; the connecting nut is provided with a second screw hole, and after the connecting nut is assembled with the second screw rod 121, an annular horizontal clamping groove 114 is formed between the bottom surface of the connecting nut and the top surface of the first fixing piece 120; the annular horizontal clamping groove 114 is used to clamp the fixed screen deck 180. The ultrasonic vibrator and the sieve tray 180 are more firmly installed, and the ultrasonic transmission efficiency is higher.

The ultrasonic vibrator further includes a connection pipe 170; one end of the connecting pipe 170 is butted with the wire guide hole, and the other end of the connecting pipe 170 is connected with an aviation plug 171; the wire 150 passes through the connecting tube 170 and is electrically connected to the aviation plug. The connecting tube 170 can protect the lead 150 and also can extend and seal the installation cavity 111, so as to prevent the installation cavity 111 from communicating with the outside through the lead hole.

The connecting pipe 170 is connected to the wire guide hole by a quick coupling of a plug-in type. The snap-fit type quick coupling is a part that can be directly purchased in the existing market, so that the connection pipe 170 and the housing 110 can be assembled and disassembled more conveniently and quickly.

An ultrasonic vibration cleaning device comprises a sieve plate and the ultrasonic vibrator which is installed with the sieve plate.
