A screw conveyor for in undamaging transport of seeds is made in the form of a frame, a cover, a screw working body with a central shaft, a drive, mechanisms of loading and unloading, and the screw is made of two parallel screw elements, which are rigidly attached to the shaft, the distance between which is equal to the length of increased diameter of a rivet and thickness of a body of an resilient element, and two ends of smaller diameter of the rivets are in interaction with the screw elements and they have rounded shape, and from above in the space between the screw elements the resilient element is mounted, whose lower base thickness is equal to the gap value between the screw elements. |
