Patent ID: 7191888

Claim:
A movable belt conveyor system intended for use as a tipping belt, the system comprising: an intermediate conveyor; a movable belt conveyor system having a direction of conveying, said intermediate conveyor being arranged upstream of said movable belt conveyor system at right angles to the direction of conveying, said movable belt conveyor system including, in the direction of conveying, a plurality of segments arranged one after another in a row, comprising a tail segment, a head element and standard segments arranged in between said tail segment and said head element; a transfer carriage displaceable on a 4-caterpillar-type moving gear for transferring the material from the intermediate conveyor to the belt conveyor system, said tail segment comprising a supporting structure connected to a supporting structure of said transfer carriage rigidly and torsionally rigidly, said caterpillar-type moving gear of said transfer carriage thus also forming a moving gear of said tail segment, said standard segments and said head segment each comprising a supporting structure and a one-caterpillar-type moving gear arranged rigidly at right angles to the longitudinal axis of the supporting structure, said tail segment, said standard segments and said head segment being connected to one another by bolts in an articulated manner, and each of said tail segment, said standard segments and said head segment accommodating carrying rollers in a carrying run and an empty belt, said tail segment being arranged as the first segment in the direction of conveying at the beginning of the conveying path and being equipped with belt drives as well as with a driving drum, said head segment being arranged as a last segment at the end of the conveying path and being equipped with a deflecting drum, a common conveyor belt being led over all of said tail segment, said standard segments and said head segment segments; and a traveling tripper which encloses said tail segment, said standard segments and said head segment in a portal-like manner, said tripper being provided for releasing material from said common conveyor belt, the traveling tripper being displaceable by a separate steerable 4-caterpillar-type moving gear and said common conveyor belt being led in a known manner as a loop over a transferring drum, which is also a driving drum at the same time, and which is in functional connection with drives and via a deflecting drum, which is also a tensioning drum, and forming a tensioning device.
