[0032] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.

[0033] Reference Figure 1 , Figure 2 and Figure 3The utility model provides a kind of sintered bulk material conveying device, including bulk material flow pipe 1 and the buffer assembly 2 of being arranged in the bending position of bulk material flow pipe 1 each, bulk material flow pipe 1 is provided with the plug valve 3 of discharge end, plug valve 3 is manual valve or electric valve, the opening of bulk material flow pipe 1 bottom end is controlled by plug valve 3.

By the setting of this structure, when bulk material is accumulated on buffer flap 21, bulk material is easy to slide to the lowest position of buffer flap 21, so as to facilitate the rotation of buffer flap 21, so that bulk material flow pipe 1 is opened to realize conveying material, bulk material is not easy to remain on buffer flap 21. The diameter of buffer flap 21 is equal to or less than the inner circle diameter of bulk material flow pipe 1, and the diameter of buffer flap 21 is greater than the inner circle radius of bulk material flow pipe 1. While ensuring that buffer flap 21 plays a role in blocking bulk material and plays a role in buffering, it can also ensure that buffer flap 21 works normally and is not easy to be stuck.

[0035] Reference Figure 1 、 Figure 2 And Figure 3The driving member 22 comprises a bearing box 221, a rotating shaft 222, a supporting rod 223 and a counterweight 224. The bearing box 221 is arranged on the bulk material flow pipe 1, and the inside of the bearing box 221 is communicated with the inside of the bulk material flow pipe 1 (in the provided drawing, the bearing box is not communicated with the bulk material flow pipe on the other side face where a closing plate is arranged, so as to ensure the sealing of the bearing box). The two ends of the rotating shaft 222 are hinged on the front and rear side faces of the bearing box 221 through bearings 4, and one end of the rotating shaft 222 extends out of the bearing box 221 along the length direction. The supporting rod 223 is arranged in the bearing box 221, one end of the supporting rod 223 is fixed on the rotating shaft 222 perpendicularly, and the other end of the supporting rod 223 extends into the bulk material flow pipe and is connected with the bottom face of the buffer flap 21.

During work, the buffer flap 21 is covered on the bulk material flow pipe 1 by the counterweight 224, when the material is conveyed through the bulk material flow pipe 1, the buffer flap 21 plays a role of plugging material at this time, when more bulk material is accumulated on the buffer flap 21, and the weight of the bulk material and the buffer flap 21 is greater than the weight of the counterweight 224, the buffer flap 21 moves downward to make the bulk material flow pipe 1 in an open state, when the accumulated bulk material is discharged through the bulk material flow pipe 1, the counterweight 224 drives the buffer flap 21 to move upward to block the bulk material flow pipe 1, and the above-mentioned action is repeated thereafter. Through the buffer flap 21 in the bulk material flow pipe 1, when the bulk material is conveyed in the bulk material flow pipe 1, the buffer flap 21 arranged can reduce the flow speed of the material, plays a role of buffering, so as to reduce the scouring of the material on the inner wall of the bulk material flow pipe 1, plays a role of protection for the bulk material flow pipe 1, and also plays a role of protection for the conveying belt 6 used for conveying the material at the bottom end of the bulk material flow pipe 1.
