Description

Technical Field

[0001] The utility model relates to the technical field of tunnel boring machine spray systems, in particular to a water distribution tray for a tunnel boring machine spray system. Background Art

[0002] During the operation of the tunnel boring machine, the spray system plays a vital role in dust reduction, cooling and improving the working environment. The water distribution plate is a key component in the spray system, and its performance directly affects the spray effect.

[0003] The water hole diameter of the traditional water distribution tray of the tunnel boring machine spray system is usually fixed, which leads to many problems in practical applications. When the tunnel boring machine faces different working conditions, such as changes in tunneling speed, rock hardness, dust concentration, etc., the water distribution tray with a fixed aperture cannot flexibly adjust the water distribution flow rate and is difficult to meet the diverse spraying needs. In a complex tunneling environment, sometimes a larger spray flow rate is required to quickly reduce dust and cool, and the water distribution tray with a fixed aperture may not be able to provide enough water; sometimes only a smaller spray flow rate is needed to save water resources, and the water distribution tray with a fixed aperture may cause a waste of water resources. For this reason, we propose a water distribution tray for the tunnel boring machine spray system. Utility Model Content

[0004] The utility model aims to provide a water distribution tray for a spray system of a roadheader to solve the problems raised by the above-mentioned background technology.
