Yen with the possibility of adjusting the angle o (. with respect to the end surface A, and P is made with the possibility of adjusting movement along the shaft 6. When the drum rotates, the UE rotates and comes into contact with P, which remains fixed.

The invention relates to belt conveyors, in particular to discharging units of belt conveyors.

The purpose of the invention is to improve the operational qualities of the discharge unit by informing the drum of forcing vibrations.

FIG. 1 shows a belt conveyor, general view; in fig. 2 - node I in Fig 4 1; in fig. 3 is a section A-A in FIG. 2

The belt conveyor discharge unit includes a frame 1 with a drum mounted on it containing a shell 2, covered by a belt 3 and rigidly connected by means of end surfaces 4 with hubs 5. The latter are mounted on the shaft 6 with the possibility of angular and axial movement relative to the shaft 6 by means of coax - the pre-deformed springs 7 arranged on it. The outer ends of the springs 7 are fixed on the shaft 6, and the inner ends - on the hubs 5. The discharge unit is equipped with a stop plate 8 mounted on the end face surface of the drum 4 at an angle d to it, and a roller 9 which have been fitted lennym on the frame 1 to cooperate with a thrust plate 8. The latter is adapted to change the mounting angle d. , is mounted on the hinge 10 and secured by a pressure bar 11. The roller 9 is adapted to move along the shaft 6 of the drum. For this purpose, a pusher 13 of the roller 9 is installed in the threaded bushing 12.

The discharge node operates as follows.

When the drum rotates, the inclined thrust plate 8, rotating with it in the direction of arrow B, smoothly comes in contact with the roller 9, which, remaining stationary, freely rotates on its axis, rolling along the inclined working plane of the plate 8,

rotates freely on its axis, rolling around on the UE. At the same time, the UE moves along with the drum by the stroke value P 7. When the UE goes down with P, sharp vibrations of the tape drum occur, which ensures self-cleaning of the tape. 1 hp f-ly, 3 ill.

pressing (moving) the latter together with the drum by the amount of stroke H in the direction of arrow B, which manifests itself in axial and angular (circumferential) deformations (excitations) of springs.

When a plate 8 rotating in the direction of the arrow B of the roller 8 comes off (roller 9), sharp drum self-oscillations occur with the tape 3 surrounding it in axial and circumferential (angular) directions relative to shaft 6 under the action of previously excited (deformed) springs 7, which tend to return to the initial state of dynamic equilibrium.

Sharp self-oscillations contribute to the detachment of particles of the transported material from the l & ensure its self-cleaning.

The drum's self-oscillation process is continuous, since for a caldah, a full turn, the forced driving of the springs is repeated as indicated

Changing the deformation of the springs, i.e. The provision of the initial guaranteed oscillation amplitude to the drum is accomplished by adjusting the angle of inclination of the plate 8 and turning the pusher 13 relative to the threaded sleeve 12, i.e. by adjusting the drum H stroke.
