Description

The known vibratory elevators, consisting of a spring-mounted pillar attached to the vibrator, supporting a cargo transporting body formed by a shelf-groove arranged along a helical line, have the disadvantage that they cannot arbitrarily change the direction of the disturbing force created by the vibrator in the device described, this disadvantage is eliminated that the vibrator is made in the form of two internal-gear sun gears coaxially mounted on a common base with the diameter of the initial circle, twice exceeding the diameter of the initial circumference of two satellites rolling on them, carrying faceplates with unbalanced weights and planted on the axis of the carrier, carrying also weights for balancing the mass of the satellites and faceplates. At the same time, to ensure the possibility of changing the magnitude of the disturbing moment created by the vibrator, the unbalanced loads are made arbitrarily movable in the axial direction.

FIG. 1 shows a diagram of one of the possible embodiments of a vibrating conveyor; in fig. 2 - side view of the vibrator; in fig. 3 - view of the vibrator from the end.

The vibration elevator consists of a rack / supporting a transporting body formed by a shelf-chute 2 arranged along a helical line 2. The base of the rack / rests on the foundation by means of springs 3. The upper rack / is connected to the cross member of the spring 4 spring 5. The vibrator is mounted on racks 6 , fastened to the top of the rack /, and is driven by a belt drive from the electric motor 7.

The vibrator consists of a plate 8, on which sub-support brackets 9 (Fig. 2) are supported, supporting the shaft 10, in the middle part of which the drive jaws 11 are wedged. At the shaft ends ./The carrier 12 and 13 are worn, offset from each other by an angle of 2P ( Fig. 3). Drove number # 120156-2 -

days, the axes of the satellites 14 and 15, which are in engagement, respectively, with the internal gearing cogwheels 16 and 17, which are rigidly fixed on the plate 8 and play the role of the solar wheels of the planetary gear. The diameter of the initial circumference of the rims 16 and 17 is twice the diameter of the initial circumference of the satellites 14 and 15. With the latter, also the faceplates 18 and 19, bearing pins 20 and 21 with the unbalance weights 22 and 23 moving along them. mounted on drove 12 and 13 additional loads 24 and 25.

When the shaft 10 rotates, the satellites 14 and 15 run around the sun wheels 16 and 17. At the same time, due to the fact that the diameter of the sun wheels is twice the diameter of the satellites, points L and L of the diameters of the initial circumference of the latter will perform oscillating linear linear movement in - a and a - a, respectively, for satellites 14 and 15. Similarly, unbalance weights 22 and 23 will move, the axes of which pass through the points A t A. Thus, the vibrator creates two disturbing forces directed to opposite sides at an angle P in the vertical axis of the conveyor and providing both rotational and translational motion of the latter. By turning the carrier 12 and 13 relative to the shaft 10, it is possible to change the direction of movement of the unbalanced weights 22 and 23. At the same time, their paths will always be perpendicular to the axes 12 and 13 when the loads 22 and 23 coincide with the centers of the sun wheels. Changing the trajectories of cargo can also be carried out by turning the faceplates 18 and 19 relative to the satellites.

The change in the magnitude of the disturbing moment created by the vibrator can also be accomplished by moving weights 22 and 25 along pin 20 and 21.

By changing the direction of the trajectory of movement of unbalanced weights and the magnitude of the disturbing moment, the vibrator can be tuned to the optimum mode that ensures the greatest performance of the vibrating conveyor.
