FIELD: construction and other industries. ^ SUBSTANCE: invention relates to devices for storing and dispensing of difficultly flowing materials, for instance, crushed chalk, tending to caking and formation of bridges. Proposed hopper contains housing, horizontal shaft installed in housing and equipped with symmetrical projections with spherical surface and provided with disks hinge-mounted on projections by means of split holders. Shaft with inclined disks is provided with axial displacement mechanism enclosed in housing. Shaft is connected with outlet guide of axial displacement mechanism mechanically coupled with pin of plane pinion whose shaft is hinge-connected with carrier. Planet pinion is in meshing with fixed gear wheel, and carrier is secured by one end in bearing support of housing, and by other end is coupled through connecting rod with crank secured on end of drive shaft of axial displacement mechanism of bridge breaker. Crank is displacement relative to axle of carrier. Owing to the fact that outlet guide is mechanically coupled with pin of planet pinion which is hinge-connected with carrier and fixed gear wheel, movement of inclined disks with continuous change of translational and angular velocities is provided which intensifies process of bridge breaking. ^ EFFECT: enhanced reliability in operation. ^ 2 dwg |
