Abstract

The invention discloses a multi-layer rockfill material screening device, and relates to the technical field of mining machinery. The multi-layer rockfill material screening device comprises a workbench, wherein a screening mechanism, a vibration mechanism, a blockage cleaning mechanism, a dust removal feeding mechanism and a screening box are arranged on the workbench, two groups of holes are formed in the outer wall of one side of the screening box, two groups of supporting frames and two groups of fixing tables are welded to the outer surface of the top of the workbench, two groups of fixing bases are welded to the outer surfaces of the front side and the rear side of the screening box, and three groups of high-strength springs are welded to the outer surfaces of the tops of the supporting frames and the fixing tables. According to the multi-layer rockfill material screening device, an operator only needs to rotate a crank on a bidirectional threaded rod to clean rockfill materialsblocked on a screen, so that the influence on the screening operation of the device due to the blockage of the rockfill materials is reduced, the screening quality of the device is guaranteed, meanwhile, the service life of the device is prolonged, the stability maintenance cost is reduced, the operation is simple and convenient, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a screening device for multi-layer rockfill materials. Background technique [0002] Rockfill material: After the rock has been blasted, there is no certain specification and size, and the dam material that can meet the design particle size and gradation requirements. [0003] At present, most of the screening devices for rockfill materials lack dust suppression measures, and a large amount of dust will be generated during use, which will cause troubles for operators and pollute the surrounding environment. Some devices still have the problem of incomplete layered screening, making it difficult to screen It is difficult for the separated stones to meet the required standards, and after a period of use, there will be a problem that the stones will block the screening parts, which will have a certain impact on the subsequent screening operations and the normal operation of...
