Abstract

A device for continuously changing the angle of a belt conveyor during operation, the purpose of which is to enable the belt to pass smoothly along a curve through a belt conveyor bend at an arbitrarily set bend angle and while maintaining the selected belt profile (for example, trough-shaped). The device consists of a roller stand, rotatably mounted in the belt conveyor frame at the bend point. The roller stand is connected by a control rod to the second part of the belt conveyor. The lower roller is located on the roller stand console. The tensioning roller is slidably mounted in a guide that is connected to the supporting structure of the belt conveyor and is connected by a rod to the roller stand. This design is advantageous because it ensures automatic alignment of the belt lengths of the upper and lower branches.

Device for continuously changing the angle of break of a conveyor belt during operation

A device for continuously changing the angle of a belt conveyor during operation, the purpose of which is to allow a continuous passage of the belt along the curve of the waist conveyor at an arbitrarily set angle of breakage and maintaining a selected belt profile (e.g. trough). The device consists of a roller stand rotatably mounted in the frame of the belt conveyor at the breaking point. The roller stand is connected by the control rod to the second part of the belt conveyor.

The bottom roller is located on the roller stand console. The feed roller is slidably mounted in a guide which is connected to the support structure of the belt conveyor and is connected by a rod to a roller stand. This embodiment is advantageous in that it ensures the self-aligning of the lengths of the upper and lower strands.

BACKGROUND OF THE INVENTION The present invention relates to a belt conveyor with a continuous change in the breakage angle of a conveyor during operation. The purpose of the invention is to allow a continuous passage of the belt along a belt conveyor break curve, where the belt retains a selected profile (eg, trough) at an arbitrarily set belt conveyor break angle, and this angle can be varied during operation.

The prior art vertical break belt conveyors have a stable roller stand arrangement at the break point providing an optimum curve for the passage of the belt at the break point for a specific break angle. This arrangement is unsatisfactory for belt conveyors where a continuous change in the break angle is required during operation, from a straight position up to the break angle given by the flow angle of the material being transported. In belt conveyors, where the break angle is variable, the passage of the belt is solved by breaking the belt conveyor through a straight roller located at the break point. This solution is unsuitable for conveyor belts with trough roller stands. At the break point, the belt is straightened transversely, the trough profile is not maintained and when the conveyor cross-section of the belt is fully utilized, the conveyed material is discharged at the break point. In order to eliminate this undesirable effect, it is necessary to reduce the filling of the belt conveyor and thus to reduce the hourly conveying capacity.

The invention solves the passage of a belt conveyor belt along a curve instead of a vertical break of the belt conveyor. The effective radius of curvature of the belt is maintained even when the angle of breakage changes continuously during operation, while automatically adjusting the belt lengths in the upper and lower branches of the belt conveyor.

The drawbacks of the prior art vertical conveyor belt conveyors are eliminated by a device for continuously changing the conveyor belt breakage angle during operation according to the invention and is based on rotatably mounted roller stands located at the ends of both belt conveyor parts the opposite part of the belt conveyor. The roller stand is rotated to the optimum position

239 119 depending on the angle of breakage and ensures that the belt passes through the optimum curve · To compensate for the difference between the length of the upper and lower strands, the automatic roller is supported by a sliding guide. · In this design, a continuous belt passage is achieved at the point where the belt conveyor breaks, maintaining, for example, a trough belt profile at an arbitrarily set angle of breakage that can be changed continuously during operation. the material to be transported at the breaking point.

In the drawing, an example of an embodiment of a device for continuously changing the angle of break of a conveyor belt during operation according to the invention is shown.

The device is located in both parts of the conveyor belt connected at the break point by a pin. The roller stand 2 is rotatably supported and is provided with a bracket on which the lower roller 4 is broken. The roller stand 2 is connected by a control bar J to the opposite part of the belt conveyor. The tension roller is slidably mounted in the guide 6 and connected by a draw bar 2 to a roller stand 2. When the break angle is changed, the draw bar 2 rotates the roll stand 2 to the optimum position and simultaneously moves the draw bar 2 the tensioning roller 2 against the lower roller to achieve equalization of the lengths of the upper and lower branches of the belt
