The present application relates to a railway rail polishing device. The traditional post-welding rail polishing mainly relies on manual operation of a hand-held grinder, which is time-consuming and laborious, and the operating environment is poor, which can easily cause occupational diseases of workers. The present application comprises two fixed arms, which are symmetrically wrapped on both sides of the rail, and the top of the two fixed arms are hingedly connected to each other. The side of the fixed arm in contact with the rail is provided with a containing groove. A position limiter is sleeved on the top hinged portion of the fixed arm, and a power assembly is arranged on the position limiter. The power assembly is engaged with the polishing belt. The polishing belt is annular, and the polishing belt is wrapped around the outer periphery of the fixed arm and the position limiter, and is simultaneously arranged in the containing groove on the inner side of the fixed arm and tightly contacts the rail. A plurality of abutting assemblies are arranged in the containing groove of the fixed arm and abut the side of the polishing belt away from the rail. The present application not only saves labor consumption, but also realizes automatic polishing and dust reduction, thereby ensuring the health of the polishing environment and avoiding harm to workers.

The utility model relates to the technical field of automatic car washers, in particular to a foam blending and diluting device for an automatic car washer, which comprises a liquid storage tank, a mixing cavity, a flow adjusting assembly and a spraying module. The flow adjusting assembly is matched with a control knob through a water pump, so that the flow of the cleaning agent is accurately adjusted; a spoiler is arranged in the mixing cavity to promote the cleaning agent to be fully mixed with water; an atomizing core is arranged in the spraying module, so that the fine and smooth degree of foam is improved; a stirring assembly is arranged in the liquid storage tank, and detergent precipitation is avoided. According to the device, real-time monitoring and dynamic adjustment are achieved through the flow meter and the controller, the problem that in the prior art, the foam concentration is difficult to adjust flexibly is solved, the cleaning efficiency and economical efficiency are improved, and meanwhile the stability and reliability of the cleaning effect are guaranteed.

The utility model relates to medicinal material processing technical field, concretely is a kind of medicinal material processing grinding equipment with dustproof function, including feed hopper, the bottom end vertical penetration of feed hopper in the top of one side of the pulverization cylinder, the middle part vertical penetration of the top of pulverization cylinder has pulverization mechanism, the bottom end outer wall of pulverization mechanism is sleeved with grinding mechanism, the bottom end outer wall of pulverization cylinder is sleeved with grinding box, the both sides inner wall sliding connection of grinding box has grinding plate, the bottom end of grinding box is equipped with discharge channel, the bottom end outer wall of grinding box is sleeved with support plate.Improved grinding equipment, grinding mechanism can further fine grinding to the medicinal material handled by pulverization mechanism, wherein grinding ball can simultaneously revolve and rotate to form double motion, increase the intensity and uniformity of grinding, the setting of dust extraction mechanism can effectively collect the dust generated in the process of medicinal material processing and grinding, avoid dust flying to air, keep the clean of working environment.
