Technical Field
[0001] The present application relates to the technical field of concrete processing, and in particular to a high-efficiency mixing mechanism with a spraying function. Background Art
[0002] A mixer is a construction machinery, mainly used to mix cement, sand, various dry mortar and other construction materials. It is a machine with a bladed shaft rotating in a cylinder or trough to mix a variety of raw materials to make a mixture or a suitable consistency. There are many types of mixers, including forced mixers, single-shaft mixers, double-shaft mixers, etc. At present, most of the mixing stations mix cement concrete, stabilized soil and asphalt concrete. When mixing, stone powder, sand, gravel and other materials that are easy to generate dust need to be added. When the mixing station is mixing, a lot of dust will be generated, causing dust pollution in the air.
[0003] In the process of concrete production, a mixing mechanism is required. When the mixing mechanism is working, the material needs to be sprayed. The spraying device in the prior art generally performs spraying by fixing the nozzle. In order to save water resources, the spraying system generally does not operate for a long time and adopts intermittent spraying operation more often. After spraying, there is always a lot of moisture remaining on the nozzle. When the dust concentration is not high, the spraying system is generally not started, which causes part of the dust generated by the sand and gravel in the silo to fall onto the nozzle. It is easy for the dust to combine with the residual moisture on the nozzle to form agglomerates and cause clogging of the nozzle, which cannot meet the use requirements. Therefore, an efficient mixing mechanism with a spraying function is proposed to solve the above problems. Utility Model Content
