Detailed Description

The following are specific embodiments of the present application and are further described with reference to the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help the embodiments of the present application be fully understood. Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1 to 3, an embodiment of the present application provides a concrete spray head assembly, including: a nozzle body 100, a metal sleeve 200; the nozzle body 100 has a feed inlet 110, an injection port 120, and an injection passage 130 formed between the feed inlet 110 and the injection port 120 and used for conveying materials from the feed inlet 110 to the injection port 120; the metal sleeve 200 is sleeved on the periphery of the nozzle body 100.

In the concrete spraying apparatus, concrete material output from a wet sprayer is mixed with compressed air to form sprayed bulk material, and spraying construction is performed through a spray head. In the present application, the compressed air carries the material from the inlet 110 of the nozzle body 100 into the injection passage 130 and is injected from the injection port 120. The technical scheme of this application is provided with metal covering 200 through shower nozzle body 100 periphery to protect shower nozzle body 100, prevent that shower nozzle body 100 from receiving the excessive deformation of inside compressed gas extrusion and damaging.

In the concrete spray head assembly provided by the application, the metal sleeve 200 and the spray head body 100 are two separable parts, so that the technical scheme provided by the application can be adapted to improve the existing spray head.

In some embodiments, the inner surface 210 of the metallic sleeve 200 and the outer surface 140 of the showerhead body 100 are attached to each other.

In some embodiments, a gap is formed between the inner surface 210 of the metal sleeve 200 and the outer surface 140 of the showerhead body 100.

One end of the nozzle body 100 at the feed inlet 110 is connected with a mixing pipe 300; the mixing pipe 300 is provided with a pipe interface 310 which is communicated with the injection channel 130 so as to inject the setting accelerator into the injection channel 130. The accelerator is injected into the injection passage 130 from the pipe joint 310 to be mixed with the concrete material. The accelerating agent is used for an additive which is mixed into concrete and can enable the concrete to be rapidly set and hardened. The accelerator can accelerate the hydration hardening of cement, and can form enough strength in a short time to ensure the construction requirement.

Specifically, an annular flow space 320 is formed between the head body 100 and the mixing pipe 300; the nozzle body 100 is provided with a through hole 150 for communicating the circulation space 320 with the injection channel 130; the flow-through space 320 communicates with the pipe connection 310 of the mixing pipe 300. The accelerator firstly enters the flow space 320 through the pipe joint 310 and then enters the injection channel 130 from the through hole 150 to be mixed with the concrete material. Further, the nozzle body 100 is provided with a plurality of through holes 150, and the through holes are uniformly distributed along the circumferential direction of the injection channel 130.

In some embodiments, the metal sleeve 200 and the mixing pipe 300 are connected together by a connector. Here, the coupling member may employ a bolt.

In some embodiments, the showerhead body 100 is a plastic material. The nozzle body 100 is made of polyurethane. In operation, concrete material flows rapidly through the injection channel 130, causing wear to the inner walls of the injection channel 130. The polyurethane has high wear resistance and is suitable for manufacturing the nozzle body 100.

In some embodiments, the metal sleeve 200 may be provided in a steel material. In addition, other types of metal materials may be provided.

The application also provides a concrete spraying device which is provided with the concrete spray head assembly provided by the embodiment of the application. For related contents, reference is made to the contents of the previous section, which is not described in detail herein.
