Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment accessories, and specifically relates to a trough-shaped automatic centering idler for a belt conveyor. Background Technique

[0002] The trough-shaped automatic centering idler, also known as the trough-shaped centering idler, is mainly used for the load-side support of a belt conveyor, and can automatically adjust the deviation of the conveyor belt, preventing it from snaking, so as to ensure the stable operation of the conveyor belt. The trough-shaped design of this idler can better adapt to the shape of the conveyor belt, providing a larger support area and stability;

[0003] For example, the utility model patent with the publication number of CN2373414Y discloses an automatic centering screw idler, which is composed of a trough-shaped idler, a parallel idler, a trough-shaped bracket 4 for supporting the trough-shaped idler, and a lower idler hanger 5 for fixing the parallel idler. The trough-shaped idler is fixed on the trough-shaped bracket 4 to form a groove shape. The lower idler hanger 5 is installed at the lower part of the trough-shaped bracket 4 to fix the parallel idler. The surfaces of the two side idlers of the trough-shaped idler and the parallel idler are respectively made into positive and reverse rotation threads along their center lines to automatically balance the centripetal thrust and achieve the automatic deviation adjustment function, which is applicable to the automatic deviation adjustment of a belt conveyor. However, there is a problem that the conveyor belt will have irregular friction with the trough-shaped idler for a long time during the conveying process, which will reduce the service life of the conveyor belt and further reduce the conveying efficiency of the conveyor belt. For this reason, we propose a trough-shaped automatic centering idler for a belt conveyor. Content of the Utility Model

A first fixed shaft is fixedly connected between the two first side plates, and a first idler is rotatably connected to the outer peripheral side of the first fixed shaft through a bearing. The bottom idler assembly can protect the bottom of the conveyor belt.

[0008] Preferably, two symmetrically arranged L-shaped mounting plates are fixedly connected to both sides of one end of the bottom plate away from the bottom idler assembly. A locking hole is provided at the outer end of each L-shaped mounting plate. The L-shaped mounting plates and the locking holes can directly mount the device to external equipment.

[0009] Preferably, the spring is arranged outside the guide post to ensure that the spring does not interfere with the guide post.

[0010] Preferably, the length of the first idler is less than the length of the first fixed shaft to ensure that the first idler does not interfere with the first side plate.

[0011] Preferably, the second idler is conical in shape, and the outer diameter of the outer end of the second idler is larger than the outer diameter of the inner end to ensure that there is always a centripetal force when the conveyor belt runs on the second idler.

The guiding plate slides on the guide post at this time, and the guiding plate drives the second fixed shaft and the second idler to adjust the angle at this time. The follower shaft performs an angle adaptive fine adjustment at this time. During the entire transportation process of the conveyor belt, the spring and the follower shaft always maintain real-time reaction force adjustment of the pressure on the conveyor belt. The utility model realizes timely support and then deviation correction of the offset conveyor belt, improving the stability of the conveyor belt on the device.

[0014] 2. The bottom idler assembly is provided to support and protect the bottom of the conveyor belt, preventing the conveyor belt from shrinking inward during transportation, which may lead to discontinuous transportation. Description of the Drawings
