What is the function of scraper conveyor with different chain number and position

According to the number and location of scraper conveyor chain, the common scraper conveyor can be divided into medium single chain, medium double chain and side double chain scraper conveyor. So what is the function of these scraper conveyors with different chain numbers and positions? Take you to see some common ones Scraper conveyor Different functions.

The middle single chain is a chain located in the center of the scraper. The scraper plays a guiding role in the middle groove to drive the coal transportation. This structure is characterized by simple structure, flexible work and good bending. There is only one chain, and the stress of the chain is relatively uniform. Therefore, the wear of the middle single chain to the middle groove and scraper is relatively small and the operation is relatively stable. But this kind of scraper conveyor coal space is relatively small, transport capacity is low, it is difficult to meet the needs of large-scale coal transportation in coal mines. The machine head is large in size and takes up large working face space. The medium and single chain scraper is mainly used in gently inclined blasting mining face of thin and extremely thin coal seam, and can be matched with small coal machine.

 Scraper conveyor

The middle and double chains are located in the middle of the scraper. The advantages of this kind of scraper conveyor are that the size of the head is small, and it is convenient to handle and replace the single strand chain when it is broken. The stress of the chain is uniform, which can reduce the wear of the middle groove and scraper. However, the energy consumption is large. Medium and double chain scraper conveyor is mainly used in fully mechanized mining face of medium thick coal seam.

Side double chain means that two chains are located at both ends of scraper. The side double chain has large space for coal passing through and strong coal drawing ability, especially suitable for pulling large hard coal. When the middle part of the chain is worn evenly, it is not easy to bend.

Middle single chain, middle double chain and side double chain scraper conveyor have their own advantages and limitations. Different coal mining face conditions are different, we must choose the scraper conveyor suitable for itself according to the actual situation and local conditions.
