Buffer device of bulk material conveyor belt end point

The invention discloses a buffer device of a bulk material conveyor belt end point, which comprises a case cover, wherein a feeding port matched with a conveyor belt is arranged on the side surface of the upper part of the case cover, and a plurality of rotatable buffer plates are arranged below the opposite side of the feeding door at the inner side of the case cover; reset torsion springs are arranged at rotating shafts of the buffer plates, and an induced draft pipe is arranged above the case cover; and a soft curtain is arranged at the feeding door, and a discharging port is arranged below the case cover. In operation, materials have a direct impact on the buffer plates after falling at a certain speed; the buffer plates are rotatably arranged in the case cover, and the torsion springs are arranged at the rotating shafts, so that the buffer plates impacted by the materials can rotate at a certain angle and has obvious effect of buffering the materials, and thus the generation of dust is greatly reduced, t
