The concrete working principle of the buffering chute of the heavy plate feeder is as follows:

feeding ore from a feed opening of the plate feeder, wherein the ore reaches the inclined slide carriage from the feed opening of the plate feeder, and slides downwards along the inclined slide carriage;

in the process of sliding downwards, the air flow is decelerated by the guide plate and finally reaches the buffer plate;

ore passes from the buffer plate to the belt.

To sum up, the utility model relates to a heavy plate feeder buffering chute, when plate feeder fed ore, the ore reachs the bottom buffer board along the slide carriage to one side, makes the ore impact force become the decurrent pressure of buffer board, and the ore level is thrown, very big reduction the impact force that the belt received. When the ore feeder stops feeding, the buffer plate can also block ores, and the ores on the belt caused by the self-flowing of the ores are prevented from being accumulated. Thereby improving the buffering effect of ore conveying and the durability of the belt.

However, it will be appreciated by those skilled in the art that various modifications may be made to the buffer chute of the heavy plate feeder for underground mines provided by the present invention without departing from the scope of the invention.
