Summary of the invention
The present invention is directed to above-mentioned technical problem to improve, intend the mounting structure that shower nozzle and current divider in a kind of wet-spraying machine are provided, can effectively prevent shower nozzle from coming off.
For this reason, the technical solution adopted in the present invention is: the mounting structure of a kind of concrete spraying machine shower nozzle and current divider, comprise shower nozzle and current divider, the afterbody of described shower nozzle is construction section, it is characterized in that: before and after on the outer wall of described shower nozzle construction section, be arranged at intervals with the first annular boss and the second annular boss, thus cavity is formed between the first annular boss and the second annular boss, first, one annular groove is respectively provided with in second annular boss, and be provided with sealing ring in per pass annular groove, described current divider is sleeved on the construction section of shower nozzle, the internal diameter of current divider and first, the external diameter of the second annular boss is equal, the first annular boss is crossed in the front end of current divider, and the 3rd hoop boss is provided with on the inwall that this crosses part, move forward to prevent the relative current divider of shower nozzle, the rear wall of described first annular boss is inclined plane, the bottom width of cavity is made to be less than top width, inclined plane has angling hole perpendicular to inclined plane and circumferentially uniform, described shower nozzle sidewall is also provided with the first just also circumferentially uniform to cavity radial hole, cavity is communicated with nozzle cavity with the first radial hole by described angling hole respectively, the sidewall of described current divider is provided with the second just also circumferentially uniform to cavity radial hole, and the diameter of the second radial hole is greater than the diameter of the first radial hole, angling hole.
Described angling hole totally 16, the first radial hole totally four, the diameter of angling hole and the first radial hole is 4mm; Second radial hole totally two, the diameter of the second radial hole is 32mm.By quantity and the size of optimization angling hole, the first radial hole, the second radial hole, guarantee that accelerator mixes with wind further full and uniform.
Further, the bore L of described shower nozzle is 55mm.By increasing former shower nozzle bore, prevent shower nozzle from occurring coming off because of interior pressing through greatly further.
Install for ease of current divider, the rear end outer wall of described current divider is provided with the 4th annular boss.
The present invention sets up first, second annular boss on existing shower nozzle afterbody outer wall, thus formation cavity, and set up on shower nozzle sidewall one ranked first radial hole and one row angling hole, accelerator and wind is made to enter cavity through the second radial hole of current divider, after fully mixing in the cavities, then entered in shower nozzle fully mixed with Gunning material with nozzle cavity by the first radial hole, angling hole respectively.Each side be provided with sealing ring at cavity, ensure that the mixed powder gas in cavity can not be revealed.3rd hoop boss is set in the front end of current divider, moves forward to prevent the relative current divider of shower nozzle.
Beneficial effect of the present invention: decrease number of parts, simplifies installation, avoids shower nozzle to occur coming off, improves operating efficiency; Ensure that high-pressure blast is press-in concrete full and uniform for accelerator, mixed like this earth just fully can mix with accelerator bottom shower nozzle, improves construction quality simultaneously, avoids the concrete after spraying to occur coming off.
