Description

Technical Field

[0001] The utility model relates to the technical field of wet spraying machine manipulators, in particular to a wet spraying machine manipulator device with adjustable air volume. Background Art

[0002] In the process of tunnel construction, wet spraying robot is one of the most important equipment. Its main function is to carry out wet spraying concrete support. The process principle of wet spraying robot is to use the power of high-pressure air fluid to mix the liquid accelerator with the premixed concrete. At the same time, the liquid accelerator is automatically proportioned and added. Through high-speed spraying, the concrete is attached to the sprayed surface, and then the concrete layer is formed through the continuous impact of aggregates and cement during spraying.

[0003] Chinese patent document CN208793014U discloses a wet spraying manipulator, which includes a concrete conveying pipe section, wherein the two ends of the concrete conveying pipe section in the length direction are respectively a first feeding end and a first discharging end, and a handheld pipe section, wherein the two ends of the handheld pipe section in the length direction are respectively a second feeding end and a second discharging end, the handheld pipe section is connected to the concrete conveying pipe section, and the second feeding end is connected to the first discharging end, an air inlet is arranged on the pipe wall of the handheld pipe section, and a nozzle is installed on the second discharging end, and the discharging channel of the nozzle is arranged obliquely with the feeding channel of the handheld pipe section. The above-mentioned wet spraying robot has shortcomings. Although the device can realize wet spraying of concrete, it has limitations. The air intake cannot be adjusted according to needs. The size of the air intake directly affects the flow rate of the sprayed concrete. The appropriate air intake can make the sprayed concrete flow rate moderate, thereby forming a relatively smooth spraying effect on the spraying surface. If the air intake is too large and the sprayed concrete flow rate is too fast, it may cause the spraying surface to be uneven, and even scattering and splashing of the sprayed concrete may occur; conversely, if the air intake is too small and the sprayed concrete flow rate is too slow, it may affect the spraying efficiency.

[0004] Therefore, in order to solve such problems, we proposed a concrete wet spraying machine manipulator device with adjustable air volume. Utility Model Content
