  • the lateral guide elements are mounted on the corresponding axes of the lateral guide elements, two elements of the same diameter on the same axis symmetrically to the longitudinal axis of the conveyor, provided that the distance from the longitudinal axis of the conveyor to the guide element increases as the diameter of the guide element increases.
  • This belt conveyor in the aggregate of common technical features is the closest to the claimed belt conveyor.
  • the conveyor belt still performed both transport and traction functions. Taking this into account, and also taking into account the significant dynamic shock loads, to increase the reliability of the conveyor as a whole, the use of a conveyor belt with a thickness of 3-4 standard layers is still required.
  • the drive of the conveyor belt into rotation by the drive drum due to friction is energy inefficient, because a large amount of energy is spent on overcoming friction forces.
  • the object of the invention is the creation of a conveyor belt, which would ensure synchronization of movement of the conveyor belt over its entire width, eliminating distortions and uneven distribution of loads.
  • the design of the conveyor belt should allow a significant increase in the pitch between the supports. At the same time, a significant reduction in the energy intensity and cost of both the conveyor belt itself and the transportation process should also be ensured.
  • the author proposed a fundamentally new approach to organizing the movement of the conveyor belt between the drive system and the tension system, as a result of which the transport and traction functions were divided between the various structural elements of the conveyor belt. So, the transport function was saved behind the conveyor belt, and the traction function was “transferred” to endless guiding elements, which in the prototype conveyor performed only the function of maintaining the shape of the conveyor belt between the supports. Taking into account one of the preferred forms of realization of endless guide elements (a conventional anchor chain or an anchor type chain in a special version), the author chose the most suitable constructive solution of the drive body, as a result of which the drive drum was "divided into many drive sprockets of the same diameter, rigidly mounted on a common drive shaft. Thus, the general concept of the conveyor belt drive has been completely changed.

  • the problem is solved in due to the fact that the guiding elements of the same diameter, located on one parallel to the longitudinal axis of the line conveyor, are interconnected by a longitudinal traction element in the form of an endless closed traction chain, connected, in turn, with the drive system and with the tension system.
  • the drive system includes a drive shaft connected to the output shaft of the electric drive and mounted on a stand perpendicular to the longitudinal axis of the conveyor, with a plurality of drive sprockets of the same diameter rigidly mounted.
  • the number of sprockets corresponds to the number of traction chains, and each sprocket forms a kinematic pair with a corresponding traction chain, and the place of installation of the sprockets on the shaft corresponds to the intersection points with the lines mentioned parallel to the longitudinal axis of the conveyor.
  • the tension system includes many independent chain tension control elements, the number of which corresponds to the number of traction chains.
  • the inventive belt conveyor due to the above design features provides significant compared with the prior art belt conveyors. So, only the “transfer” of the traction function from the conveyor belt to the endless traction chains eliminates significant energy costs for overcoming the friction forces between the drum and the conveyor belt, which leads to a decrease in the energy intensity of the conveyor belt as a whole while increasing energy efficiency. In addition, the absence of friction also ensures a decrease in belt wear and, therefore, the possibility of using a conveyor belt of a much smaller thickness, up to one layer, over a longer period, which, while increasing the durability of the belt, can significantly reduce the cost of the conveyor as a whole.
  • traction chains are more flexible in comparison with the conveyor belt (especially 3-4-layer), which eliminates the occurrence of stresses and fractures during the movement.
  • the inventive belt conveyor in addition, has a higher degree of unification of parts and assemblies and contains only standard parts and products more limited than the conveyors from the prior art of the nomenclature, which significantly increases maintainability and reduces the cost of manufacturing and repair.
  • all the drive sprockets have the same diameter and synchronously rotate with the same angular and linear speeds.
  • the guide elements of the guide bearing system have different diameters and rotate with different angular but identical linear speeds. Since the diameter of the guide elements is different, the endless traction chains have different lengths corresponding to the diameter, and for synchronization of tension, each closed traction chain closes with an independent element of the chain tension control, which is provided for this as part of the tension system.

  • the inventive belt conveyor structurally involves various options for placing the conveyor belt.
  • an endless closed conveyor belt can be laid on endless closed traction chains and can cover a separate non-drive drum located behind the drive system and chain tension control elements from the tension system.
