Abstract
Analysis of experience in the operation of belt conveyors confirms the main advantages of conveyor transport - a high level of productivity, based on automation of equipment, the ability to transport a wide range of goods and low production costs. They are one of the main means of continuous technological transport when loading coal, ore, gravel in seaports. The use of belt conveyors not only in coastal but also as part of ship cargo complexes necessitated the creation of highly productive belt conveyors with a long service life. Significant capital costs for the purchase of belt conveyors are offset by low operating costs. The unit cost of cargo conveyor belts is lower than that of other vehicles used in marine transshipment complexes. The practice of using belt conveyors of known constructions of different purpose, design and size shows that all without exception, these conveyors have a fundamental drawback - the rapid destruction of the elements of the suspension of the belt. Dynamic shocks during loading and relocation of cargo lead to an even greater reduction in the service life of the belt and suspension, as well as a significant increase in energy consumption of the transport process. These processes lead to premature failure of the conveyor, loss of cargo, dust pollution and loss of its quality during transportation. Belt conveyors have improved so much that they have actually reached a certain "threshold of modernization", beyond which there are no real ways to improve performance in the traditional scheme of the roller conveyor. This is confirmed by the fact that in recent years, patent authorities in the world issue single patents in the field of conveyor construction, which are not essential for the further development of this promising and necessary mode of transport. The problem is solved by the fact that the damping system of the conveyor belt, consisting of a base, dampers made of magnetorheological elastomer, power supply and control, and characterized in that the dampers made of elastomer-ru, fixed on the base, are made in the form of three concentric cylinders -ditch of different heights, in a shell of high molecular weight polyethylene, the signal to control the properties and the order of involvement of which comes from the load and shock sensors located under the base at the place of loading.
