Abstract

The damping shield in the conveyor belt is fixed to the steel structure of the driving station by means of a beam. On the beam, a damping shield central part is attached to which the upper part of the damping shield, fixed by a hydraulic cylinder fixed to the cross member, is fixed by means of upper pins. By means of the lower pins, a lower part of the damping shield is mounted to the central part of the damping shield, controlled by a lower hydraulic cylinder fixed to the cross member. A cross bolt is attached to the beam to rotate the center of the damping shield

Damping shield in the conveyor belt of the long-distance conveyor belt

The damping shield in the conveyor belt transfer is fixed to the steel structure of the driving station by means of a beam. The central part of the damping shield is attached to the beam, to which the upper part of the damping shield is actuated by means of upper pins, controlled by a hydraulic cylinder mounted on the crossbeam. By means of the lower pins, the lower part of the damping shield is actuated to the middle part of the damping shield operated by the lower hydraulic cylinder mounted on the crossbeam. A cross pin is mounted on the beam to swivel the middle part of the damping shield

BACKGROUND OF THE INVENTION The present invention relates to a damping shield in an overfill of a belt conveyor of a long distance belt conveyor.

At present, one of the ways to increase the efficiency of long-distance belt transport is to increase the time utilization of the given technological unit. The purpose of the damping shield is to damp the kinetic energy of the minus, to concentrate and direct the flow of minus to the next conveyor with a certain forward speed. The mined must be loaded symmetrically onto the next conveyor to prevent the conveyor belt from turning laterally with all the negative consequences for the conveyor operation. The fossil must fall on the damping shield at a Z-30 ° angle in order to avoid excessive sticking to the damping shield's working surface.

The current design of the damping shields does not always meet the requirements of its functions. If the angular overfill is to meet the requirement of the amount of angle under which the damping impact on the damping shield is met, the symmetric loading condition favors the next conveyor because the material will hit the hopper side of the next Jbo conveyor followed by the conveyor belt.

The above mentioned drawbacks are eliminated by a damping shield in the overfill of the belt conveyor of the long-distance belt conveyor fastened to the steel structure of the driving station by means of a beam according to the invention. the lower part of the damping shield operated by the lower hydraulic cylinder mounted on the cross member is attached to the middle part by means of a cylinder mounted on the crossbeam and by means of lower pins. A cross pin is mounted on the beam to swivel the middle part of the damping shield. The central part of the damping shield can be pivoted and tilted due to the steel structure of the driving station.

Both upper and lower damping shield can be tilted using the hydraulic cylinder and lower hydraulic cylinder opposite the plane of the central damping shield ·

The use of the cushioning shield in the conveyor belt conveyor of the long-distance conveyor belt according to the invention is universal and can be used for both wagons and excavators and stackers · The cushioning shield in the conveyor belt cladding reduces both the number of of the transfer point resulting from the buckling of the conveyor belt and subsequent contamination of the space of the return station of the conveyor belt or mobile hopper.

In the accompanying drawing, a damping shield is schematically shown in the overfill of a belt conveyor of a long distance belt conveyor according to the invention.

On the steel structure of the driving station X, by means of the beam 2, the central part X of the damping shield is fixed, to which the upper part J of the damping shield is attached by means of upper pins. X · By means of the lower pins 8, the lower part 2 of the damping shield is fixed to the central part χ of the damping shield, whose position compared to the central part X of the damping shield is built by the lower hydraulic cylinder 10 «. The working position of the beam 2 is determined so that the flow of the live 12 falls predominantly on the central part X of the damping shield.

At any angle of the downstream conveyors, the middle section X of the damping shield can be adjusted so that it falls on the main flow minus 12 in the overfill, the upper part J of the damping shield can be tilted by the hydraulic cylinder 6 to maintain the angle. The lower part 2 of the damping shield can again be lowered by means of the lower hydraulic cylinder 10 relative to the plane of the central part X of the damping shield, so that the flux 12 reaches the center of the conveyor belt of the adjacent conveyor. A certain amount of forward speed in the direction of the next conveyor can be imparted to the flowable 12 by rotating the damping shield.
