Rigid-flexible coupling self-adaptive bucket wheel device

Abstract

The invention discloses a rigid-flexible coupling self-adaptive bucket wheel device. The device comprises hoppers uniformly distributed on a body of a bucket wheel in the circumferential direction, wherein the bottom ends of the hoppers are hinged on bucket wheel cross beams; hopper bodies are flexibly connected with longitudinal beams of the bucket wheel through telescopic connecting rod components; each telescopic connecting rod component comprises a telescopic cylinder with one end hinged on the corresponding bucket wheel cross beam, a first connecting rod with one end hinged on the corresponding hopper body and a second connecting rod with one end hinged on the corresponding longitudinal beam of the body of the bucket wheel; and the other ends of each telescopic cylinder, each first connecting rod and each second connecting rod are movably hinged together. According to the rigid-flexible coupling self-adaptive bucket wheel device, the telescopic connecting rod components are arranged between the hoppers and the longitudinal beams of the bucket wheel, and the advantages of the telescopic mechanisms and the connecting rod mechanisms are combined, so that the opening and closing angles of the hoppers are increased while guaranteeing the flexible coupling contact between the hoppers and the ground, thus material taking and clearing operations are directly and efficiently completed, and the operation efficiency is improved.

Description

Technical field [0001] The invention relates to a bucket wheel equipment, in particular to a rigid-flexible coupling adaptive bucket wheel device. Background technique [0002] Bucket wheel stacker-reclaimers are widely used in large and medium-sized bulk terminals, mine yards and other places, and have many advantages. However, the reclaiming operation of the bucket wheel stacker-reclaimer has the disadvantage of a large amount of residual materials, that is, after the reclaiming is completed, the remaining materials of the storage yard with a thickness of about 500mm cannot be removed. This is because the cantilever frame of the bucket wheel stacker-reclaimer is very long and the yard floor is uneven. When reclaiming materials, the bucket wheel mechanism is too close to the ground and there is a risk of collision with the ground. The bucket wheel mechanism is a rigid body, and a collision will cause damage to the yard ground. In severe cases, the bucket wheel stacker and recla...
