Abstract
The utility model relates to a guide slip shoe for a coal mining machine, which aims to overcome the defects that as serious accidents like sticking and teeth-breaking frequently occur to the conventional coal mining machine, the production is influenced, the service life of the equipment is shortened, a great economic loss is brought to production enterprises, the cost for coal mining is increased, and the normal development of national economy is affected. The guide slip shoe for the coal mining machine includes a slip shoe main body for the coal mining machine (1), wherein an elliptical hole (2) is formed at the center at the upper part of the slip shoe main body for the coal mining machine and connected with a circular shaft (3), and one surface of the slip shoe main body is inclined. The guide slip shoe for the coal mining machine is used for mining coal.
