Elastic supporting structure of drying cylinder

Abstract

The invention relates to an elastic supporting structure of a drying cylinder. The elastic supporting structure comprises a rolling ring, elastic plates and the drying cylinder, wherein the bottom surfaces of the elastic plates are soldered onto the drying cylinder, and the top surfaces of the elastic plates are soldered onto the rolling ring; the elastic plates, the drying cylinder and the rolling ring are combined to form a whole body; an external driver drives the rolling ring so as to drive the drying cylinder to rotate. The structure is simple and reasonable, and the probability of unsoldering of the elastic plate and the rolling ring is low. Meanwhile, as the elastic plates are flexible, when the drying cylinder is expanded with heat and contracted with cold, force can be directly applied to the elastic plates, the circular degree of the rolling ring is unlikely to be abnormal, asphalt stirrer equipment is not easily damaged, and the normal operation of the equipment can be ensured.

Description

technical field [0001] The invention relates to an elastic support structure of a drying cylinder, in particular to the elastic support of the drying cylinder in an asphalt mixer; it belongs to the technical field of mechanical equipment. Background technique [0002] In the prior art, the support of the drying cylinder in the asphalt mixer is usually composed of a rolling ring, a pad iron, and a drying cylinder; the bottom surface of the pad iron is welded on the drying cylinder, the top surface is welded on the rolling ring, and the external drive Drive the rolling ring to drive the drying cylinder to rotate. The support of the drying cylinder with this structure needs to be heated to a higher temperature. After a long time of operation, it often expands with heat and contracts with cold, which may easily lead to desoldering between the pad iron and the rolling ring. At the same time, because the pad iron is cast steel The components have no stretchability. When the dryi...

Problems solved by technology

The support of the drying cylinder with this structure needs to be heated to a higher temperature. After a long time of operation, it often expands with heat and contracts with cold, which may easily lead to desoldering between the pad iron and the rolling ring. At the same time, because the pad iron is cast steel The parts have no stretchability. When the drying cylinder expands with heat and contracts with cold, the force is directly applied to the rolling ring, which will easily cause the roundness of the rolling ring to be abnormal and cause equipment damage.
