Scraper conveyor is a kind of coal conveying machine for working face and roadway. Scraper conveyor can be divided into two types: middle double chain scraper conveyor and side double chain scraper conveyor?

Middle and double chain scraper conveyor

The two circular chains of the middle double chain scraper conveyor are fixed on the scraper with e-bolts in the middle of the scraper, and the center distance of the chain is not more than 20% of the middle slot width. Because the chain does not run in the channel side steel and the diameter of the link is not affected, the strength of the chain can be increased, so it can be applied to the heavy and super heavy scraper conveyor. Due to the advantages of the chain, such as uniform force, good bending performance, the use effect is better. The disadvantage is that the running resistance is high, and in the case of hard coal and large coal block, the transportation effect is not good and it is not easy to use.

The long chain segment is adopted for the middle and double chain, and the two chains must be matched for delivery and use, so as to ensure a small deviation in their length and reduce the uneven stress.

Side double chain scraper conveyor

The two circular chains of the side double chain scraper conveyor are connected with the scraper by connecting rings at both ends of the scraper. The length of each chain is the distance between the scraper. Therefore, the chain is short. The chain and the connecting ring run in the groove of the groove side steel. The scraper has large space and can transport large coal blocks. This kind of chain has small pretension, small running resistance and strong adaptability. Therefore, it is widely used. The disadvantage is that the two chains are not evenly stressed, the scraper is easy to skew, the middle of the scraper is subject to large stress and easy to bend; because the chain link and the connecting ring run in the groove. The space is affected, the larger ring chain cannot be used, and the strength is affected.
