FIELD: industry and agriculture. ^ SUBSTANCE: invention relates to classification of loose materials according to sizes. Proposed grader has screening surface in form of end less rod plates with calibrating meshes and drive and drive shafts arranged within their outline. Push-out device of components of handled mass stuck in calibrating meshes is installed on end section of working leg inside outline of each plate over drive or driven shaft. Said pus-out device is made form of tilted shaped plate with lugs on ends by means of which push-out device is secured on frame across direction of movement of rod plate. Working part of push-out device is made in form of guide clamp, and tilted surface is made slightly convex to increase rigidity of clamp. ^ EFFECT: reduced damage to components of handled mass, prevention of breaking of equipment and violation of process. ^ 1 dwg |
