A vibration platform 4 is fixedly connected to the top of the connecting column 3. A vibration motor 5 is fixedly connected inside the connecting column 3. A connecting ring 6 is sleeved on the side surface of the vibration motor 5. Copper fins 7 are circumferentially and evenly distributed on the outer wall of the connecting ring 6. A fan frame 8 is fixedly connected to the bottom inner wall of the vibration machine housing 1. An upper protective filter screen 9 is fixedly connected to the top of the fan frame 8. A silent fan 10 is fixedly connected inside the fan frame 8. A lower protective filter screen 11 is fixedly connected to the bottom of the fan frame 8.

[0022] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 show, a fixing column 12 is fixedly connected to the side surface of the vibration machine housing 1. A protective block 13 is fixedly connected to one side of the fixing column 12. A test bench body 14 is fixedly connected to the bottom of the protective block 13. A hollow groove 15 is opened inside the test bench body 14.

[0023] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 show, a ventilation slot 2 is opened at the top of the vibration machine housing 1. The ventilation slot 2 is in a plum blossom shape, and the inner wall of the ventilation slot 2 is treated by frosting.

[0024] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 show, the vibration motor 5 is fixedly connected inside the connecting column 3. The vibration motor 5 is fixedly connected to the vibration platform 4 through the connecting column 3.

[0025] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, copper fins 7 are evenly distributed circumferentially on the outer wall of the connecting ring 6. The copper fins 7 are in an inclined "Z" shape and the number is at least one, which is used to increase the contact area and duration of the air flow in the vibrating machine housing 1. The copper fins 7 are snap-connected to the side surface of the vibrating motor 5.

[0026] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an upper protective filter screen 9 is fixedly connected to the top of the fan frame 8. The upper protective filter screen 9 covers the top of the fan frame 8. The perpendicular distance from the end of the copper fin 7 far from the axis of the vibrating motor 5 to the axis of the connecting column 3 is less than the radius of the silent fan 10, and the length of the upper protective filter screen 9 is greater than the diameter of the silent fan 10. A lower protective filter screen 11 covers the bottom of the fan frame 8, and the length of the lower protective filter screen 11 is greater than the diameter of the silent fan 10.

[0027] The working principle and usage process of the present utility model: When the vibrating motor 5 in the vibrating machine housing 1 is running, the outside air can enter through the ventilation slot 2 opened at the top of the vibrating machine housing 1. The ventilation slot 2 is in a plum blossom shape and its inner wall is treated by frosting, which will greatly improve the efficiency of the air entering the vibrating machine housing 1. In addition, a connecting ring 6 is sleeved on the side surface of the vibrating motor 5.

The perpendicular distance from the end of the copper fin 7 far from the axis of the vibrating motor 5 to the axis of the connecting column 3 is less than the radius of the silent fan 10, ensuring that the silent fan 10 can blow and dissipate heat from the vibrating motor 5 sufficiently. The upper protective filter screen 9 and the lower protective filter screen 11 cover the top and bottom of the fan frame 8 respectively, playing a certain dust-proof and protective effect. The upper protective filter screen 9 on the top of the fan frame 8 can further limit the wind force and wind flow of the silent fan 10, further improving the cooling effect in the vibrating machine housing 1. The hollow groove 15 opened inside the test bench body 14 can also promote the air circulation at the bottom of the vibrating machine housing 1. The vibrating machine housing 1 is installed on the test bench body 14 together with the protective block 13 through the connection of the fixing column 12.
