The application discloses an aggregate dust removal device for a large concrete mixing station and relates to the dust removal device field.The aggregate dust removal device comprises a conveying device, a dust falling assembly is arranged on one side of the conveying device, and the dust falling assembly comprises a dust filtering unit, a spraying unit, a separation unit and a vibration unit.The dust filtering unit comprises a dust filtering plate, a plurality of dust filtering holes are formed in the dust filtering plate, the dust filtering plate is arranged to be inclined to the conveying device direction and extends above one end of the conveying device, and the spraying unit is arranged on the side of the dust filtering plate close to the conveying device.The dust on the aggregate is cleaned through the cleaning water, the dust on the aggregate is treated more completely, a large amount of dust is prevented from being raised in the subsequent conveying and processing of the aggregate, the cleaning water and the sludge can be continuously separated, the filter cloth belt has the effect of continuous filtration, the dust in the aggregate is more quickly and completely filtered through the dust filtering plate, the spraying on the aggregate is improved, the cleaning effect on the aggregate is improved, and the impact and beating effect on the dust filtering plate and the filter cloth belt is better.

This utility model relates to the field of bearing processing technology and discloses a drilling device for bearing production. The device includes a body assembly and a support plate. The top of the support plate has a moving groove, and the outer periphery of the top of the support plate has an installation groove. This utility model uses three circumferentially distributed adjusting components and a double-sided gear linkage mechanism to synchronously drive multiple clamping parts to move radially, achieving precise concentric clamping of the inner and outer rings of bearings of different diameters. The transmission structure of the lead screw and the driven bevel gear ensures consistent displacement of each clamping part. Combined with the rubber anti-slip texture design, it effectively prevents bearing slippage and reduces surface damage during clamping. The dual positioning mechanism of the positioning plate and the clamping plate further ensures strict concentricity of the inner and outer rings, significantly improving the drilling position accuracy, effectively reducing vibration and noise problems caused by eccentricity, and extending the service life of the bearing.
