Detailed description of the invention
A kind of coal mining machine roller as depicted in figs. 1 and 2, comprise a core 1 and the end plate 2 being arranged on described cylinder core 1 one end, the outer wall of described cylinder core 1 is provided with and extends and the blade 6 laid in the shape of a spiral along cylinder core 1 length direction, the lateral surface of described end plate 2 and the lateral surface of described blade 6 are provided with toothholder 4, described toothholder 4 is provided with pick 3, the defeated coal side of described blade 6 is provided with in fan-shaped wearing plate 8, the short arc limit 8-1 of described wearing plate 8 coordinates with the wall contacts of described cylinder core 1, the long arc limit 8-2 of described wearing plate 8 is near the edge of described blade 6, described wearing plate 8 is connected with blade 6 by bolt 5, described wearing plate 8 is provided with multiple wear-resistant block 9 away from a side of blade 6.In the present embodiment, described wearing plate 8 is arranged on the coal outlet of described blade 6 afterbody.Described wear-resistant block 9 is welded on wearing plate 8.
In the present embodiment, this coal mining machine roller can realize the integral demounting to wearing plate 8 and wear-resistant block 9, when there is heavy wear and need to change in wearing plate 8 and wear-resistant block 9, can dismantle the wearing plate 8 worn and torn and wear-resistant block 9 in down-hole very easily, and the new wearing plate 8 of Fast Installation and wear-resistant block 9, thus do not affect the normal operation of coal mining machine roller, improve production efficiency.When concrete installation wearing plate 8 and wear-resistant block 9, in advance wear-resistant block 9 is welded on wearing plate 8, when mounted, wearing plate 8 is provided with the one side of composite wear-resistant block 9 upwards, two straight flanges of wearing plate 8 are imported to cylinder core 1 direction, then by the bolt 5 through blade 6, wearing plate 8 is connected on blade 6.When disassembly is desired, above-mentioned flow process is installed, reverse operating.
