简述了针对现用采煤机不能适应大倾角工作面双向割煤的情况,设计了一种新型采煤机,通过在一级牵引单元增加采煤机的牵引功率和牵引力,实现大倾角工作面条件下采煤机双向截煤。
Aiming at the situation that the existing coal shearer can not be adapted to the bidirectional cutting of coal in a large inclined face, a new type of coal winning machine is designed. The steep working angle is achieved by increasing the traction power and traction of the shearer in the first traction unit Shearer under the condition of two - way cut coal.
