Side double chain scraper for coal mine is the key equipment used for material transport in coal mine production, and its structural design and functional features are optimised for the specific working environment and needs of coal mine. The following is a detailed introduction of side double chain scraper for coal mine:
1. Definition and Function
Definition: side double chain scraper for coal mine is a kind of scraper conveyor with side double chain design, which is mainly used in underground coal mine or other occasions that need to transport bulk materials continuously.
Function:
- Continuous transport: through the continuous movement of the scraper chain, bulk materials such as coal, gangue, etc. are transported from one place to another.
- Strong load carrying capacity: the side double chain design makes the scraper have higher load carrying capacity and stability, which is suitable for transporting materials in large quantity and long distance.
- Strong adaptability: it can adapt to the complex and changeable working environment of underground coal mine, such as inclined roadway, curved roadway and so on.
2. Structure and Composition
Coal mine side double chain scraper is mainly composed of the following parts:
- Machine head: including electric motor, reducer, transmission device, etc., providing power for scraper chain.
- Middle groove: it is the main part of scraper machine, connected by several grooves, used to support scraper chain and transport materials.
- Scraper chain: adopts side double chain design, composed of scraper, chain and connecting ring, etc. It is responsible for scraping and transporting materials.
- Tail part of the machine: including sprocket, tensioning device, etc., which is used to adjust the tensioning degree of scraper chain and guiding.
3. Working Principle
The working principle of coal mine side double chain scraper is to drive the reducer through the motor, the reducer drives the chain wheel to rotate, and then drive the scraper chain to circulate in the central trough. The scraper on the scraper chain scrapes the material from the head of the machine and transports the material to the tail of the machine with the movement of the chain, completing the whole conveying process.
4. Features and Advantages
- Strong bearing capacity: the side double chain design makes the scraper have higher bearing capacity and stability, which can meet the demand of large quantity and heavy load material transport.
- Strong adaptability: it can adapt to the complex and changeable working environment of underground coal mine, such as inclined roadway, curved roadway, etc. Meanwhile, it has strong anti-impact and wear-resisting ability.
- Convenient maintenance: the structure of scraper is relatively simple, easy to maintain and overhaul, reducing maintenance cost and time.
- Smooth operation: through precise transmission and tensioning devices, it ensures that the scraper chain remains smooth and stable during operation, reducing vibration and noise.
5. Application Examples
Coal mine side double chain scrapers are widely used in the underground transport system of various coal mines, such as coal mining, roadway excavation, working face advancement and other occasions. They not only improve the efficiency and safety of coal mine production, but also reduce the labour intensity and cost of workers.
6. Maintenance and upkeep
In order to ensure the normal operation and prolong the service life of the side double chain scraper for coal mine, regular maintenance and repair work is required. This includes checking the wear and tear of the scraper chain, the loosening of the fasteners, the lubrication status of the transmission device and so on. When serious wear or damaged parts are found, they should be replaced or repaired in time. In addition, it is also necessary to keep the scraper clean and dry to prevent the effects of corrosion and rust on its performance.
To sum up, coal mine side double chain scraper is one of the indispensable and important equipments in coal mine production, and its structural design and functional features are optimised for the specific working environment and needs of coal mine. In the process of use, it needs to pay attention to the maintenance and repair work to ensure its normal operation and extend its service life.
