One end of the ultrasonic stirring rod is rotatably installed inside the stirring tank, and the other end of the ultrasonic stirring rod is located outside the top of the stirring tank. The spreading plate is coaxially fixedly installed on the ultrasonic stirring rod and rotates to be located above the inside of the stirring tank. The spreading plate covers the bottom of the feed pipe. The ultrasonic stirring rod is fixedly connected to an electric drive mechanism. The ultrasonic system of the ultrasonic stirring rod is fixedly installed on the top of the stirring tank.

[0018] The present invention will be further described below with reference to the accompanying drawings: Example Reference Figure 1-3 A mixing device for silver-coated copper powder includes a mixing tank 1, wherein: the mixing tank 1 is provided with a mixing mechanism and an electric drive mechanism for driving the mixing mechanism to rotate; the top of the mixing tank 1 is provided with at least one feed inlet 2 so that the material required for silver-coated copper powder can enter the mixing tank 1 through the feed inlet 2; the bottom of the mixing tank 1 is provided with a discharge pipe 3 so that the silver-coated copper powder after mixing can be discharged from the mixing tank 1. Specifically, the mixing mechanism includes an ultrasonic stirring rod 4 and a spreading plate 5. One end of the ultrasonic stirring rod 4 is rotatably installed inside the mixing tank 1, and the other end of the ultrasonic stirring rod 4 is located outside the top of the mixing tank 1. The spreading plate 5 is coaxially fixedly installed on the ultrasonic stirring rod 4 and rotates above the inside of the mixing tank 1. The spreading plate 5 covers the bottom of the feed inlet 2. The ultrasonic stirring rod 4 is fixedly connected to the electric drive mechanism so that the ultrasonic stirring rod 4 rotates under the drive of the electric drive mechanism, and at the same time drives the spreading plate 5 to rotate, so that the material falls onto the spreading plate 5. The spreading plate 5 spreads the material and prevents the material from accumulating and entering the mixing tank 1. Specifically, the ultrasonic system of the ultrasonic stirring rod 4 is fixedly installed on the top of the mixing tank 1 so as to achieve vibration through ultrasonic waves, thereby further improving the mixing quality of the materials entering the mixing tank 1.

[0019] Specifically, the electric drive mechanism includes a motor 12, a main pulley 13, a belt 14, an auxiliary pulley 15, and a gantry frame 16. The main pulley 13 is fixedly installed at the output end of the motor 12, and the auxiliary pulley 15 is fixedly installed on the ultrasonic stirring rod 4 exposed outside the mixing tank 1. The main pulley 13 and the auxiliary pulley 15 are connected by a belt 14. This structure facilitates the connection between the ultrasonic stirring rod 4 and the ultrasonic system. The motor 12 is fixedly connected to the top of the mixing tank 1 through the gantry frame 16 to ensure the stability between the motor 12 and the mixing tank 1.

[0020] Specifically, a support shaft 17 is rotatably installed between the main pulley 13 and the mixing tank 1 to ensure the stability between the main pulley 13 and the mixing tank 1.

[0021] Specifically, a bearing 7 is provided between the ultrasonic stirring rod 4 and the stirring tank 1. The bearing 7 is fixedly connected to the stirring tank 1 and rotatably connected to the ultrasonic stirring rod 4, so as to ensure the stability between the ultrasonic stirring rod 4 and the stirring tank 1 through the bearing 7.

[0022] Specifically, a spiral blade 6 is fixedly installed on the outer surface of the ultrasonic stirring rod 4. The spiral blade 6 rotates inside the mixing tank 1 and is located below the spreading plate 5. By setting the spiral blade 6, the material inside the mixing tank 1 can be better stirred when the ultrasonic stirring rod 4 rotates outside.

[0023] Specifically, the ultrasonic system includes a conductive slip ring 8, a housing 9, wires 10, and a support arm 11. The rotor part of the conductive slip ring 8 is fixedly connected to the end of the ultrasonic stirring rod 4 exposed outside the mixing tank 1. The stator part of the conductive slip ring 8 is fixedly connected to the housing 9 through the support arm 11 to ensure the stability of the conductive slip ring 8. The housing 9 is fixedly installed on the top of the mixing tank 1. The ultrasonic generator inside the housing 9 is electrically connected to the stator wire harness of the conductive slip ring 8 through the wires 10. The rotor wire harness of the conductive slip ring 8 is electrically connected to the ultrasonic stirring rod 4. With this structure, the connection between the ultrasonic stirring rod 4 and the ultrasonic generator is not affected when the ultrasonic stirring rod 4 rotates.

[0024] In this embodiment, during use, the ultrasonic stirring rod 4 is driven to rotate by the electric drive mechanism, and the ultrasonic generator is started. Then, the material required for the silver-coated copper powder is put into the mixing tank 1 through the feed pipe 2. Due to the setting of the spreading plate 5, the material will fall onto the spreading plate 5, and under the rotation of the spreading plate 5, the material is scattered to prevent the material from accumulating and falling into the mixing tank 1. At the same time, the spiral blades 6 will stir the material, and under the action of the ultrasonic generator, the ultrasonic stirring rod 4 will vibrate and transmit the vibration to the material, thereby improving the stirring quality of the material.
