[0002] The scraper is a transport machine used in coal mining working faces. It is mainly used for coal mining working faces and mining area chute transportation, and can also be used in coal tunnels and semi-coal rock tunnel excavation working faces. It can transport upwards or downwards, and the upward transportation is generally not more than 35 degrees. The downward transportation is generally not more than 25 degrees, and it is better to not exceed 20 degrees in practice. The scraper has the advantages that the transportation capacity is not affected by the size and humidity of the cargo, the height of the machine body is small for easy loading, the length of the machine body is easy to adjust, and the machine body is strong and can be stepped on the working face of the coal, so it is widely used in many town coal mines.
