Description

one

This invention relates to mining equipment.

According to the main author. St. 166272 a belt conveyor is known, which includes the belt driving circuit and intermediate chain loops with traverses on the traveling wheels and end heads.

The distinction of the proposed conveyor is that it is equipped with a tape installed between the adjacent end sprockets of intermediate chain loops by damping roller supports. This allows the conveyor to be loaded with lump cargo at several points along its length.

FIG. 1 shows the scheme of the described conveyor; in fig. 2 is the same; the section along A-A in FIG. one; in fig. 3 - the same, a cut but bb in fig. one.

The conveyor includes a load-carrying drive belt I, an envelope of the drive drum 2 and a tension drum 3. The upper branch of the tape is supported by arcuate traverse 4 with running wheels 5 but not moving along the guide rails 6. The empty belt branch moves but with stationary roller supports 7.

The traverses are connected by non-driven chain contours 8, enveloping the end stars 9 and 10. One of the asterisks is made

tension. The chains under the ribbon form several closed infinite contours.

Between the asterisks of the adjacent chain loops, there are shock-absorbing roller-supports 11 (made for example of pneumatic tires) under the belt, which form intermediate loading points.

When the conveyor is operating, loading is carried out at one of the intermediate points.

Lunar cargoes, such as ore, during loading fall not on the traverse, but on the shock-absorbing supports 11, which significantly reduces the impact dynamic loads and increases the reliability of the conveyor. In this case, rigid traverses of a simple construction can be used, since they do not experience shock loads during intermediate loading.

Subject invention

Belt conveyor but auth. St. 166272, characterized in that, in order to ensure that the conveyor can be loaded with lumpy cargo at several points along its length, it is equipped with damping rollers supported under the belt between adjacent end sprockets of intermediate chain loops.
