Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a novel carrying type grooved idler includes a base 10 disposed on a ground, a rotating shaft 11 extending upward along a vertical direction is disposed on the base 10, and an axis of the rotating shaft 11 is collinear with an intersection line of two vertical symmetric planes of the base 10. A carrier roller support 20 is connected to the rotating shaft 11, a buffer carrier roller 21 is horizontally arranged on the carrier roller support 20 along the length direction of the base 10, and two vertical symmetric surfaces of the carrier roller support 20 and the buffer carrier roller 21 are superposed with two vertical symmetric surfaces of the base 10.

Common carrier rollers 22 are hinged to both ends of the carrier roller support 20, and the two common carrier rollers 22 are symmetrically distributed along the symmetry plane of the base 10. The common carrier roller 22 is provided with a damping part 30, the damping part 30 comprises a guide block 31 hinged to the upper end of the common carrier roller 22, and the axes of the hinged parts of the upper end and the lower end of the common carrier roller 22 are parallel to each other, so that the vibration of the common carrier roller 22 is always in the same plane. A support bar 32 is provided below the guide block 31, and a guide chute is provided inside the support bar 32. The guide block 31 is located in the guide chute, and the guide block 31 slides in the guide chute in the rotational direction of the normal idler 22.
