Powdery accelerating agent adding device for spraying pipeline of wet concrete spraying machine
The invention relates to a powdery accelerating agent adding device for a spraying pipeline of a wet concrete spraying machine. The powdery accelerating agent adding device comprises a material cabin (1), material discharging nozzles (6), a tube body (3), a moving rod (4), air inlet nozzles 2 and a communicating passage, wherein the material cabin (1) is used for containing powdery accelerating agents; the material discharging nozzles (6) is communicated with the spraying pipeline of the wet concrete spraying machine; the tube body (3) is communicated with the material cabin (1) and the material discharging nozzles (6); the moving rod (4) is arranged in the tube body (3) and is glidingly connected with the tube body (3); each air inlet nozzle (2) is communicated with the tube body (3); the communicating passage is arranged on the moving rod (4) and is used for communicating the discharging-out end opening part of the material cabin (1) and the material discharging nozzles (6). The communicating passage contains the powdery accelerating agents, and the moving rod (4) moves in the tube body (3), so that the discharging-out end opening part of the material cabin (1) is communicated with the material discharging nozzles (6); and a screw rod mode is not used for transportation, so that the process of adding the powdery accelerating agents into the spraying pipeline is realized.
