The shearer has three distinctive features: First, it is more adaptable under the harsh geological conditions of a very thin coal seam with a large dip angle (0.4 to 0.7 m thick). The second is to solve the problem that the small tooth box and hydraulic system of the shearer's traction part heat up quickly and the temperature is high, which leads to many mechanical failures. The maximum traction of the machine can reach 100 Newtons, the traction speed is 3 meters per minute, and the coal mining propulsion can be increased by 10% to 25%. Thirdly, the coal-filling box and the coal-cutting box are welded as a whole, which enhances the stability and safety of the equipment.
An anchor assembly that enables anchor points for weight lift and for height entry or fall protection. The assembly of the present disclosure generally includes: a stud, an external elongated surface with load-bearing threads, and a through tunnel fabricated on the stud , the through-tunnel intersects and is perpendicular to the longitudinal axis of the stud; member comprising an eyelet surrounding the opening and a pair of retainers extending from the eyelet, each retainer defining a hole at its central axis , and defines a hole having a diameter 0.1 to 2 mm larger than the diameter of the stud; the retainers are spaced apart from each other for receiving the stud through the hole, and are axially aligned with a cavity of predetermined length; a nut with sidewalls , the sidewall defines an internally threaded passage through which the nut is fixable to the stud and located within the cavity for insertion between the pair of retainer members, the nut on the side The wall has a pair of axially aligned and radially extending through holes; the through holes are adjustably aligned with the passage tunnel to form a continuous passage thereof; and a pivot pin that can be filled through the through holes and Passage through the tunnel to lock the nut onto the stud. The eyelet of the assembly of the present disclosure is configured to be rotatable about the longitudinal axis of the stud, and the locked nut prevents movement of the member along the longitudinal axis of the stud.
