Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveyors, in particular to a discharging structure of a scraper conveyor for a mine. BACKGROUND

[0002] In the process of coal mining, the scraper conveyor plays an important role. The coal powder or coal blocks mined in the mine are put into the feeding port of the scraper conveyor by the excavating equipment. Under the driving of the scraper conveyor, the coal powder or coal blocks can be transported to the discharging port or discharging channel at the other end, thereby realizing the function of long-distance transportation.

[0003] In the existing scraper conveyor, the sealing structure is generally used to block the discharging port during discharging, thereby adjusting multi-point discharging. The existing sealing mechanism is usually a lifting structure that needs to use a large lifting force to lift the sealing plate of the sealing mechanism to close it. If the sealing mechanism adopts a descending mode, the sealing plate also needs to be lifted to open the discharging port and make the channel unobstructed. If there are accumulated coal blocks in the channel, the channel may be stuck or pressed, which makes it difficult to open and delays the discharging progress, which is not conducive to production.
