Abstract
Screw transporter has been developed, which consists of the vertical tube-column, to which the horizontal loading branch is fixed rigidly in the upper part being able to revolve, and in the bottom part – the unloading branch is fixed. Loading and unloading branches are similar in design and are separate units with the separate electric drives located horizontally. Screw shafts are fixed rigidly to the ends of the electric drives shafts and inserted into the tubes. The other ends of the shaft are inserted into the tube ends piers. The second end of the tube of loading and unloading branches is limited by the stopper, with the help of which they are fastened to the tube-stoppers of the upper and bottom branches, which in their turn are fixed to the electric drives stoppers by the second end. Tube-stoppers of the upper and bottom branches can revolve. In the upper part of the tube-stopper of the unloading branch a cylinder hole is made to supply the bulk-cargo from the top downwards. Besides, the loading and unloading branches are equipped with the stopper mechanisms, one of which is located in the upper part of the tube on the loading branch, and in the bottom, in the lower part of the unloading branch. Stopper mechanisms are made as step-by-step cylinder rollers, which are fixed rigidly to the stoppers and stopping bushes welded to the tube-column. Stopper mechanisms are fixed rigidly to the tie links, which are mounted through the bushes by the stoppers to the vertical tube-base, which is fixed to the frame. The supply of the bulk-cargo from the heap is performed by the left end of the loading branch. The unloading of the bulk-cargo in the unloading branch 3 is performed by the screw 6 through the exit into the tank. The upper loading branch is mounted on the tube-column, the angle of its inclination to the horizon being adjusted by the known-design mechanism. The bottom branch is mounted at the inclination angle to the horizon. Besides, the screws of both branches are rigidly fixed to the shafts with uniformly increased steps along the length of the upper branch towards the supply of the bulk-cargo in the place of the tube-column hole, and the bottom branch towards the exit of the bulk-cargo from the transporter.
