The supporting mechanical equipment includes manipulator, air compressor, water supply system, batching and mixing feeding device, accelerator adding device, etc. The common concrete spraying device needs to use a spray gun for spraying during operation, but after long-term operation, the concrete adhered to its inner wall will harden, making it impossible to be effectively cleaned, so the existing improved device will continue to stir and clean it, but with this design, the concrete at the end will slowly harden and dry, which is still easy to block the subsequent normal operation of the spray head.

[0003] After searching, the Chinese patent document (authorization announcement number CN218952820U) is a concrete spraying device for construction, wherein a spray gun head is installed on the top of the clamping frame, a transmission cylinder is installed on the left side of the spray gun head, a feed pipe is connected to the left side of the bottom of the spray gun head, the feed port of the feed pipe is connected to the inside of the concrete storage box, and the inner cavity of the transmission cylinder is fixedly installed with connecting plates on both sides, and the inside of the connecting plates is provided with a slide groove, and the inside of the slide groove is plugged with a slider, and the end of the slider located outside the slide groove is fixedly connected with a transmission push rod. The concrete spraying device for construction drives the rotation of the transmission screw by rotating the rotating wheel, thereby driving the left and right movement of the transmission push rod through the tooth groove, and then drives the movement of the disc and the scraper, so that the inner wall of the spray gun head can be scraped, preventing the inside of the spray gun head from being blocked. The improved device will continue to stir and clean it, but with this design, the concrete at the end will slowly harden and dry, and it is still easy to block the subsequent normal operation of the spray head.
