FIELD: construction.SUBSTANCE: mechanical grid comprises a trash stack with a row of parallel bars on grid beams, scrapers with a row of parallel teeth on beams of scrapers for cleaning of the grid. The trash stack and scrapers are made as demountable. The grid beam is equipped with a detachable angle. Eyes of grid bars may be inserted into through holes of the grid beam. The protruding part of eyes from through holes in the grid beam is equipped with slots for insertion of the upper part of one of angle shelves into them, and the other shelf of the angle is fixed by a bolt joint to one of the shelves of the grid beam channel to form a lock joint.EFFECT: unification of structure elements for commercial production of a standard device, faster assembly and adjustment of a device, simplified repair of a grid and scrapers, increased reliability of device operation.3 cl, 6 dwg |
