The coal mining scraper conveyor is in a closed rectangular area, and the bulk materials are continuously conveyed through the moving scraper chain. During horizontal transportation, the material is subjected to the pressure of the scraper chain in the direction of movement and the weight of the material itself. There will be internal friction between the materials. This friction guarantees a stable state between the layers and is sufficient to overcome the material. The external frictional resistance due to the movement in the machine box causes the material to be transported as a whole flow.
1. The coal mining scraper conveyor uses a high-strength mine circular chain to drag the scraper, and uses a concave tooth sprocket to drive. It has the characteristics of large bearing capacity, long chain life and high strength.
2. The chain of the coal mining scraper conveyor and the return part of the scraper are supported by the support roller, which not only saves labor and reduces friction, but also helps the chain to automatically tension and slide by automatically changing the deflection between the scrapers. Several support rollers for the return chain.
3. If the coal mining scraper conveyor is driven in the upper part of the head and the chassis is self-integrated, the entire installation can be installed and operated freely without the need for anchor bolts.
4. If the chain of the coal mining scraper conveyor can be automatically tensioned, this can ensure that the chain always runs under moderate tension for a long time without manual, timely and frequent tensioning operations.
