Further, as shown in fig. 3 and 6, the first side support 27 is provided with a plurality of adjusting holes 271, the adjusting holes 271 are distributed along the length direction of the first side support 27, the first adjusting plate 29 is provided with an oblong hole 291 corresponding to the adjusting hole 271, when the adjusting device is installed, the adjusting holes 271 are opposite to the oblong hole 291, and the adjusting holes 271 penetrate through the adjusting holes 271 and the oblong hole 291 through the bolt connector 213, so that different height positions of the first adjusting plate 29 on the first side support 27 are fixed, and further, the angle adjusting operation of the first adjusting carrier roller 22 is realized. Similarly on the side of the second side strut 28.

Further, as shown in fig. 3 and 7, a locking groove 272 is provided on the first side support 27, and a locking groove extending longitudinally is similarly provided on the second side support 28, taking the second side support 28 side as an example, when the second adjusting idler 23 is installed, a part of the idler shaft protrudes outside the second adjusting plate 210, the locking groove is reserved on the second side support 28, and an installation space is reserved for the protruding part of the idler shaft, so that the idler shaft is prevented from interfering with the second side support 28 during angle adjustment, and the normal operation of the adjusting operation is ensured. The same applies to the first side stay 27.

Further, the groove depth of the longitudinally extending clamping groove at the upper end of the first side support 27 and the second side support 28 is deeper than the groove depth of the clamping interfaces for fixing the carrier roller on the first adjusting plate 29 and the second adjusting plate 210, so that the adjustment operation can be normally carried out within a required angle range.

On the basis of the above-described embodiment, as a further limited embodiment, as shown in fig. 8 and 9, the bracket structure 2 further includes a rubber spacer 211, and the rubber spacer 211 is disposed between the first side pillar 27 and the first adjusting plate 29 and/or between the second side pillar 28 and the second adjusting plate 210.

Specifically, as shown in fig. 8, the rubber gasket 211 is provided to increase the friction between the first side post 27 and the first adjusting plate 29 and/or between the second side post 28 and the second adjusting plate 210, so as to ensure stable connection between the adjusting plates and the side posts after the angle adjustment.

Further, as shown in fig. 9, the rubber gasket 211 is shaped to correspond to the shape of the adjustment holes of the first side support 27 and the second side support 28, and is cut according to the field situation.

Example 2

The embodiment provides a belt conveyor, which comprises the transition carrier roller group provided in embodiment 1 and a conveying belt located above the transition carrier roller group.

Specifically, because the belt conveyer is the overall structure that other components are combined to the transition bearing roller group, therefore the belt conveyer naturally has all the advantages of transition bearing roller group, and the redundant description is omitted here.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
