[0047] A pulling block 12 is respectively fixed to the top of the lower support block 11 and the bottom of the dust suppression cover 3.

[0048] A return spring 13 connects the two pulling blocks 12. When the lower pressing plate 8 is not under pressure, it can drive the lower pressing plate 8 to return to the horizontal position to close the feed pipe 2 and prevent external impurities from entering the inside of the feed pipe 2.

[0049] A dust suppression cover 3 can rotate inside the feed pipe 2.

[0050] An inclined support plate 6 is fixedly connected inside the feed pipe 2, which can prevent dust from rising while ensuring that the powder can be smoothly fed into the feeder 1.

[0051] A mounting block 7 is fixed to the inner wall of the feed pipe 2.

[0052] A lower pressing plate 8 is installed inside the mounting block 7 through a rotating shaft.

[0054] Connecting rope 10 connects two connecting blocks 9. The powder is poured into the feed pipe 2. Under the action of gravity, the lower pressing plate 8 descends. Driven by the connecting rope 10, the dust suppression cover 3 is pulled to cover the top of the feed pipe 2, leaving only a filling space for feeding. At the same time, the powder enters the feed pipe 2 and descends step by step along the inclined support plate 6. The raised dust is pressed by the inclined support plate 6 and the dust suppression cover 3 and will not escape outside the feed pipe 2.

[0055] Discharge pipe 4 is connected to the output end of the conveyor 1. Discharge bin 14 is installed on the left side of the conveyor 1. Discharge pipe 4 is connected to discharge bin 14.

[0058] Clamping frame 5 moves within the side range of the discharge pipe 4. During discharging, the electric push rod 16 pushes the clamping frame 5 to clamp the bag mouth. The raised dust at the bag mouth is recovered under the suction of the dust suction port 17, greatly avoiding the dust escape during discharging.

[0059] The surface of the clamping frame 5 is adhered with an anti-slip rubber pad 21, which increases the clamping friction and prevents the bag mouth from loosening.

[0060] Dust suction port 17 is opened inside the clamping frame 5.

[0061] Connecting pipe 18 is connected to the dust suction port 17.

[0062] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0063] An anti-dust device for a powder conveyor provided by the present invention, when in use, the powder is poured into the feed pipe 2. Under the action of gravity, the lower pressing plate 8 descends. Driven by the connecting rope 10, the dust suppression cover 3 is pulled to cover the top of the feed pipe 2, leaving only a filling space for feeding. At the same time, the powder enters the feed pipe 2 and descends step by step along the inclined support plate 6. The raised dust is pressed by the inclined support plate 6 and the dust suppression cover 3 and will not escape outside the feed pipe 2. During discharging, the electric push rod 16 pushes the clamping frame 5 to clamp the bag mouth. The raised dust at the bag mouth is recovered under the suction of the dust suction port 17.
