This invention discloses an automatic dust collection and charging base for vacuum cleaners with a display screen. The display screen allows for real-time monitoring of the device's operation, enhancing visibility and facilitating timely component inspection and adjustment. This ensures efficient and stable operation and ease of use. The charging structure features a charging rack with a clamp and conical guide groove, improving positioning stability during charging. Designed linkages and micro-switches in the charging components prevent accidental contact with conductive plates, enhancing safety. The dust collection structure includes a bottom positioning structure with upper and lower positioning rings that engage and lock together, and an embedded exhaust filter with a pull rod, improving ease of assembly and disassembly. Compared to common dust collection and charging bases, this design achieves efficient dust collection, safe charging, and convenient assembly and maintenance.

The utility model provides a civil construction gravel humidifying device which comprises a conveyor, a transmission belt is arranged on a machine frame of the conveyor, a water tank is arranged on one side of the conveyor, a high-pressure water pump is fixedly arranged on the outer surface of the water tank, and a water suction pipe and a water outlet pipe are arranged on the high-pressure water pump. Compared with the prior art, the utility model has the following beneficial effects: after humidification, because transported sand and stones are in a humidification state, when the wet sand and stones are transported, certain adhesion is generated between the wet sand and stones and the transmission belt in contact with the wet sand and stones, a certain amount of sand and stones are occupied on the transmission belt, and after the adhered sand and stones are transported to the position of the scraper blade, bristles are arranged on the scraper blade and are in contact with the transmission belt; therefore, the sand and stones on the transmission belt are scraped, the situation that the more and thicker the sand and stones are collected, the conveying burden of the transmission belt is increased is effectively avoided, the situation that the transmission belt stained with the sand and stones is left on the transmission belt, and the subsequent sand and stone humidifying work is finally affected is avoided, and the design is easy to operate and has good practicability.

The utility model relates to the technical field of welding, in particular to an electrical automation welding machine which comprises a welding table and a machining mechanism, the machining mechanism comprises a top frame, a sliding frame, two illuminating lamps, an adjusting assembly, two clamping assemblies and a welding assembly, and clamping screws in the clamping assemblies are matched with limiting rods. A worker can conveniently and manually adjust the height of a clamping plate to adapt to machined parts of different sizes, the worker can also rotate a rotating rod and an adjusting screw rod in an adjusting assembly in the welding process to change the relative position of an adjusting seat so as to facilitate welding, the design operation is simple, and the problems that the machined parts are inconsistent in size and height, and the welding quality is poor are solved. The problems that a good clamping effect on a machined part is inconvenient to achieve, and the stabilizing effect is poor are solved.
