[0002] High-frequency vibrating fine screens are efficient and precise material grading equipment. Their core working principle involves a high-frequency vibrating motor generating excitation force, causing the screen to vibrate at high frequency and low amplitude. This achieves rapid stratification and precise screening of materials. By adjusting the vibration frequency and screen inclination angle, it can adapt to the screening needs of different materials, significantly improving the automation level of the production line and product quality. The feeding device is a crucial structure of the vibrating fine screen. Traditional feeding devices are funnel-shaped structures, allowing materials to enter through the funnel under their own gravity. The outlet opening of the feeding device is small, causing the discharged material to accumulate in the middle of the vibrating fine screen, resulting in poor material distribution uniformity and affecting the working effect of the high-frequency vibrating fine screen.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a high-frequency vibrating fine screen uniform feeding device, including a distribution pipe 1, a distribution spiral 2 inside the distribution pipe 1, the spiral direction of the distribution spiral 2 being reversed from the middle position, a power motor 3 at one end of the distribution pipe 1, a hopper 4 at the middle position of the upper surface of the distribution pipe 1, five discharge ports 5 sequentially provided at the lower end of the distribution pipe 1, a distribution cover 6 below the distribution pipe 1, the lower end of the discharge ports 5 being connected to the distribution cover 6, and a distribution beam 7 provided inside the distribution cover 6 at the position corresponding to the discharge ports 5.

[0018] In use, the material to be fed is poured into the hopper 4. Under the action of gravity, the material enters the distribution pipe 2. The power motor 3 drives the distribution screw 2 to rotate. Since the two ends of the distribution screw 2 rotate in opposite directions, when the distribution screw 2 rotates, it transports the material inside the distribution pipe 1 to both ends of the distribution pipe 1. The material continues to be output outward through the five discharge ports 5 set at the lower end of the distribution pipe 1. A distribution hood 6 is set below the discharge port 5, and a distribution beam 7 is set inside the distribution hood 6. The material falling from the discharge port 5 continues to be distributed through the distribution beam 7, so that the material is fed into the high-frequency vibrating fine screen more evenly, thereby ensuring the uniformity of material screening of the high-frequency vibrating fine screen.

[0019] The material distribution pipe 1 has end plates 8 at both ends. The main shaft of the material distribution screw 2 is rotatably connected to the end plates 8 through bearings. A reducer 9 is provided on the outer surface of one end plate 8. The main shaft of the material distribution screw 2 is connected to the power output end of the reducer 9. The power motor 3 is connected to the power input end of the reducer 9. The end plates 8 at both ends of the material distribution pipe 1 close the two ends of the material distribution pipe 1. At the same time, the material distribution screw 2 is rotated into the inside of the material distribution pipe 1 through the bearings. The reducer 9 is provided on one side of the end plate 8 to reduce the power of the power motor 3 and transmit it as the rotation of the material distribution screw 2.

[0020] The lower end of the hopper 4 is provided with an inlet 10. The size of the inlet 10 and the outlet 5 corresponds to that of the distribution pipe 1. The lower end of the hopper 4 and the inlet 10 are connected by an inlet cover 11. The inlet cover 11 has a rectangular funnel-shaped structure. The material inside the hopper 4 is collected through the funnel-shaped inlet cover 11 and fed into the inside of the distribution pipe 1 through the inlet 10.

[0021] The lower end of the discharge port 5 is connected to the material distribution cover 6 via a discharge cover 12. The discharge cover 12 has a rectangular funnel-shaped structure. The funnel-shaped discharge cover 12 connects the material distribution cover 6 to the lower part of the discharge port 5, thereby ensuring the uniformity of material distribution.

[0022] The upper end of the material distribution beam 7 is a sharp structure facing upwards. The sharp structure of the material distribution beam 7 is set at the middle position of the discharge port 5. Through the material distribution beam 7 with its sharp structure design, the material falling onto the material distribution beam 7 is distributed under the action of the sharp structure, thereby improving the uniformity of material distribution.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
