A screw conveyor with a movable trough is made in the form of a frame, where are installed a trough with a screw working element, an actuator, a loading hopper and an unloading window with a container. On the left end of shaft of the screw working body a pulse coupling of known design is set with an oblique disk, which is in interaction with a stop of axial movement, which is rigidly fixed form below of the left end of the trough, on the free right end of the shaft a nut is screwed, which is in interaction with an end of a compressed spring, which is fitted thereon, and the second end of the spring is in interaction with an end of support rigidly mounted on the frame, and the free end of shaft is in interaction with an elliptical groove of support with possibility of circular turning and oscillating movements, and from below the trough, on the left, is mounted on the spring is possibility of oscillation in the vertical plane, in addition, the drive shaft of screw working body from both ends is mounted into the end surfaces of the trough through resilient bearing bushes. |
