Technical Field

The utility model relates to a spraying device of a concrete mixing plant, in particular to a canned spraying mechanism of finished concrete.

Background

The concrete mixing plant is a combined device for intensively mixing concrete, which is also called a concrete prefabrication field, and can ensure the quality of the concrete and save cement. When the concrete mixer works, after the concrete is proportioned, the finished concrete is stirred by the concrete mixer, and then the finished concrete is loaded and transported.

In order to respond to the environment protection requirement, the concrete canning vehicle needs to be sprayed in and out of the mixing plant, so that a spraying device is arranged at the gate of the factory, and the concrete canning vehicle needs to be sprayed cleanly through the spraying device to enter and exit the gate. In the discharging process of the concrete stirring main machine, finished concrete is easy to splash on the surface of the canning truck, sometimes more truck at a stirring station, the truck after canning sometimes needs to be parked in the stirring station for a long time, if the sun is too large and the temperature is higher, the concrete on the surface of the canning truck can start to solidify when not going out, and after solidification, the truck is sprayed and is difficult to wash, the canning truck is very high, and manual cleaning is inconvenient. Moreover, the sewage recovery tank of the mixing station is generally built in a production area near a concrete mixing host, is far away from a factory gate, and the concrete flushed from the concrete canning vehicle can flow back to the sewage recovery tank only by a long sewage ditch, and can be solidified or blocked by a bottom when not flowing into the sewage tank, so that the cleaning is very troublesome. To this end, the bottom of the existing concrete mixer main machine is modified.
