Description
Technical Field
The utility model relates to a coal-winning machine technical field especially relates to a novel spiral machine coal mining machine.
Background
The integrated coal mining machine BShK-2DM produced in batches by the national factory Malyshiev 2010 has great defects in design and technology according to the operation experience of Ukrainian and China mines, and due to the defects, the actual indexes of coal yield and productivity are only 50-70% of the design.
The main defects of the existing integrated coal mining machine are as follows: complex and unreliable locking connections; the diversion speed of the auger is low (4.5 m/min); the lack of support means and effective screw locking means on the machine; a discrete control system with complex body position and low efficiency is executed in the coal bed; the value of the forced sweep of the formation soil is at least 0.6 m, the side falling from the formation and the lack of movement of the machine over the height of the formation (up to 300 mm), greatly limiting the range of application, since the sweep values vary from 0 to 1 m in the work passing along the formation; the difference between the longitudinal axis of the feed mechanism and the level of rotation of the gearbox of the helical mill results in a shoulder of 0.45 metres and, in the case of a feed force of 40000 kg, an overturning moment of 18000 kg, which has a negative effect on the movement of the gearbox on the guide of the machine. The tilting moments acting on the machine frame and the rotor gearbox and on the guide rails lead to severe wear of the sliding bearings on the guide rails and the rolling bearings of the rotor gearbox. In addition, the reducer can also bear the feeding force and the dynamic load in the process of destroying and transporting the non-static coal. For this reason, complex gearing and guiding systems are subject to large static and dynamic loads, reducing the reliability of the machine.
