[0024] Sealing plate assembly 4: Figure 4 As shown, the top of the feed frame 3 is blocked, the size of the feed port can be adjusted according to demand, and a rotating plate made of a material that absorbs noise in the air is used to achieve noise reduction;

[0025] The sealing plate assembly 4 includes a fixed plate 41 and a rotating plate. The fixed plate 41 is installed on the feed frame 3. The rotating plate is provided with two groups, including a first rotating plate 42 and a second rotating plate 43.

The first rotating plate 42 and the second rotating plate 43 are limited between the fixed plate 41 by limiting bolts 44. The fixed plate 41 has the same size as the rotating plate. The three can be spliced ​​together to completely block the top of the feed frame 3.

[0026] A lower mounting seat 6 is installed on the top outer wall of the vibration frame 1, and an upper mounting seat 5 is installed on the bottom outer wall of the feed frame 3. The upper mounting seat 5 corresponds to the lower mounting seat 6 in position. A shock-absorbing pad 7 is also provided between the feed frame 3 and the vibration frame 1. The lower mounting seat 6 and the upper mounting seat 5 are connected by connecting bolts 8. The shock-absorbing pad 7 absorbs the vibration transmitted from the vibration frame 1 to the feed frame 3.

[0027] The side wall of the vibration frame 1 is connected to an excitation source 13 via a mounting plate 14. Two groups of mounting plates 14 are provided, which are respectively connected to the vibration frame 1 and the feed hopper 12. The outer cover of the excitation source 13 is provided with a noise reduction component 9, which is used to reduce the noise of the excitation source 13.

[0028] An anti-blocking member 11 is installed on the inner wall of the vibration frame 1 through a connecting plate 10 to prevent material accumulation. The anti-blocking member 11 is conical and is coaxially arranged with the vibration frame 1. There are four groups of connecting plates 10, which are arranged in a circular array around the center of the anti-blocking member 11.

[0029] Noise reduction component 9: Figure 3 As shown, the cover is arranged on the outside of the excitation source 13, absorbing the noise generated by the excitation source 13 while not affecting the normal operation and heat dissipation of the excitation source 13;

[0030] The noise reduction component 9 includes a noise reduction frame 95 and a baffle 91. The noise reduction frame 95 is a rectangular shell that is transparent on the left side and the front and back sides. The front side of the noise reduction frame 95 is connected to the mounting plate 14 through the baffle 91. The front and back sides of the noise reduction frame 95 are respectively provided with filter windows 94. The noise reduction frame 95 is provided with a first noise reduction plate 92 and a second noise reduction plate 93 from the inside to the outside.

The first noise reduction plate 92 and the second noise reduction plate 93 are both provided with through holes 96, and the through holes 96 on the first noise reduction plate 92 and the second noise reduction plate 93 are staggered.

[0031] The working principle of this utility model is as follows: when using the device, the device is connected to the power supply, and according to the size of the feed opening, the sealing plate assembly 4 is adjusted, the limiting bolt 44 is turned counterclockwise to release the limit between the first rotating plate 42 and the second rotating plate 43 and the fixed plate 41, and the positional relationship between the first rotating plate 42 and the second rotating plate 43 and the fixed plate 41 can be adjusted to adjust the size of the feed opening of the feed frame 3. After the adjustment is completed, the limiting bolt 44 is turned clockwise to limit the first rotating plate 42 and the second rotating plate 43 to complete the adjustment;

[0032] Start the excitation source 13, which drives the vibration frame 1 and the hopper 12 to vibrate through the mounting plate 14. Add the material from the feed port. The vibration frame 1 drives the anti-blocking member 11 to vibrate through the connecting plate 10, which can effectively avoid the blockage of the material and discharge it smoothly from the hopper 12.

[0033] When the excitation source 13 is working, it generates noise. The noise is absorbed by the first noise reduction plate 92 and the second noise reduction plate 93 in the noise reduction assembly 9, thereby reducing the leakage of noise. Under the action of the filter window 94 and the through hole 96, the heat generated by the excitation source 13 during operation can be exchanged with the outside world, without affecting the normal operation of the excitation source 13.

[0034] The excitation source 13 drives the vibration frame 1 and the anti-blocking member 11 to vibrate, and contacts with the material. The noise generated by the collision will be transmitted upward and absorbed by the sealing plate assembly 4 on the feed frame 3, reducing the noise emission and thus achieving noise reduction.
