Description

Technical Field

[0001] This invention relates to the field of scraper reclaimer technology, specifically to a bridge-type scraper reclaimer based on intelligent control of unmanned yards. Background Technology

[0002] Scraper reclaimers, traveling on horizontal tracks, are designed for use in open-air stockyard warehouses or storage buildings. They scrape material and convey it to parallel stockpiles on either side of the equipment via cantilever arms mounted on one or both sides. Due to their ability to convey material to parallel stockpiles on either side of the equipment, scraper reclaimers offer highly efficient and reliable stacking and reclaiming capabilities. Single-arm, paired-arm, and double-arm models feature separation mechanisms that allow for direct conversion from unloading to loading. Bridge-type scraper reclaimers are best suited for mixed material applications and, in many cases, for covered storage to maintain material dryness. Linear scraper reclaimers move along horizontal channels to stack and reclaim materials in stockyards.

[0003] A prior art technology discloses a bridge-type scraper reclaimer based on intelligent control of unmanned storage yards (application number CN201711079655.2). It includes a main beam with two sets of rakes symmetrically arranged on both sides. The upper part of the rakes is connected to a tower at the top of the main beam via pulleys and wire ropes. A rake support structure and hydraulic cylinders are connected below the rakes. A scraper assembly is connected to the bottom of the main beam. The bottom ends of the main beam are respectively supported on side beams A and B. A drive wheel set and a driven wheel set are respectively located at the bottom of side beams A and B. A feeding belt is connected to the end of the scraper assembly. The hydraulic cylinder drives the rakes to move left and right, causing the material to roll and slide freely during the movement of the entire machine. The hydraulic cylinder ensures driving force and stability, while the rake support structure ensures the stability and flexibility of the rake structure. The bottom scraper assembly evenly rakes the material onto the feeding belt, preventing material scattering and protecting the belt. Buffer rollers on the feeding belt buffer the falling speed of the material, ensuring complete material transmission.

[0004] However, existing technologies, especially this particular solution, still have the following problems:

[0005] The fixed structure of the rake conveyor cannot adapt to changes in the profile of the material pile: The rake of the existing bridge scraper reclaimer is usually a rigid integral structure, which relies solely on the drive to achieve overall swing or translation. It cannot dynamically adjust the local shape of the scraping component according to the depressions or irregular surfaces that gradually form in the material pile during the reclaiming process. This results in a decrease in the adhesion between the scraper and the surface of the material pile, which easily creates blind spots or residues in the reclaiming process, affecting the efficiency and uniformity of the reclaiming process.

[0006] The material conveying path is prone to be interrupted during the rake adjustment: when the rake is adjusted in angle or position, the connection between the rake and the downstream conveying device lacks flexible transition structure, which may cause material spilling, blocking or discontinuous conveying during the transfer, especially under large angle adjustment condition.
