Abstract
The invention discloses a coal digging machine comprising a hydraulic system, a mechanical hand (16), a mobile device (17), a turning device (18), an electrical system (7) and a base (9), wherein the mechanical hand (16) comprises a bucket (22), a bucket oil cylinder (23), a small arm (24), a forearm oil cylinder (25), a large arm (20) and a large arm oil cylinder (21); the mobile device (17) comprises a mobile oil cylinder (12), a slide platform (11), a slide carriage (14), an inlaying strip (13), a basal plate (10) and a changeable bed (15), wherein the slide platform (11) is fixed with themechanical hand (16), and the mobile device (17) enables the mechanical hand (16) fixed on the slide platform (11) to longitudinally move back and forth; and the turning device (18) comprises a supporting seat (1), a supporting frame (2), a turning oil cylinder (3), a turning arm (4), a turning bearing seat (5) and a large arm supporting seat (6) and enables the mechanical hand (16) fixed on the large arm supporting seat (6) to transversely move left and right. The invention adopts full hydraulic transmission, has compact structure, large driving force, high automation degree and coal diggingefficiency, stable work, high reliability, easy operation, good durability and long service life.
Description
technical field [0001] The invention relates to coal mining equipment, in particular to a coal excavator with high coal mining efficiency. Background technique [0002] With the continuous innovation of science and technology, the continuous acceleration of industrial modernization, the continuous progress of modern civilization and the depletion of natural resources, coal mining mechanization is being promoted in an all-round way. The traditional blasting hand coal mining method not only has low production efficiency, high labor intensity, but also poor safety; while the existing coal mining machinery such as coal cutters is not suitable for non-open-pit coal mines, and has high requirements for the working face. The huge investment cannot meet the production needs of many small and medium-sized coal mines in the south. Contents of the invention [0003] Aiming at the problems existing in the coal mining machines in the prior art, the present invention provides a coal mi...
