When the buried scraper conveyor is conveying horizontally, the material is subjected to the pressure of the scraper chain in the direction of movement and the weight of the material itself, which generates internal friction between the materials. This friction ensures the stable state between the material layers. And it is enough to overcome the external friction force generated by the movement of the material in the machine tank, so that the material forms a continuous overall material flow and is transported. When the material is vertically lifted, the material is subjected to the pressure of the buried scraper conveyor scraper chain in the direction of movement, and the material The horizontal side pressure is generated in the middle, and the buried scraper conveyor forms the internal friction of the material. At the same time, due to the continuous feeding of the lower horizontal section, the lower material successively produces a pushing force on the upper material. This friction and pushing force are sufficient Overcoming the external frictional resistance caused by the movement of the material in the tank and the weight of the material itself, the buried scraper conveyor makes the material form a continuous overall flow and be lifted.
The movable sprocket of the buried scraper conveyor adopts a concave tooth type. The chain will not drop even after the chain is severely worn and the circumference is enlarged, which greatly extends the chain replacement cycle. The chain tension adjustment adopts a worm gear deceleration and self-locking tensioning mechanism, which saves effort and is easy to operate, and ensures synchronous tensioning on both sides. The high-strength mining circular chain of the buried scraper conveyor is used as the conveyor chain, which has large carrying capacity and wear resistance. The material is divided to separate the return chain and the scraper from the material, avoiding the occurrence of blockage of the chain scraper caused by the sudden increase of the feed volume and the full machine warehouse.
