An inspection pan of mine scraper conveyor comprises face and goaf sidewalls rigidly connected to each other by lower and upper bottoms, in the case the upper bottom is made with an inspection hole, which edges have shoulders, the goaf sidewall is made with a through groove, on the shoulders and in the through groove of face sidewall a cover is installed. The height of through groove of face sidewall is greater than the thickness of cover for the value of a gap sufficient for setting the cover through the groove. The inspection hole and cover have a trapezoidal shape. On the outer side of the face sidewall a quick release latch is mounted fastening the cover. |
