During excavation, there is more than one tunnel. When excavating a new tunnel branch, since it is newly opened, the ventilation measures in the original tunnel cannot be extended to the newly excavated area, resulting in the visibility and safety of the excavation not being guaranteed. It is necessary to design ventilation measures during excavation. When excavating a new tunnel, traditional ventilation measures are difficult to install and will affect the excavation work. Based on this, the present application provides a tunnel excavation ventilation component 4, including a tunnel excavation component 1 for tunnel excavation and a driver 3 arranged under the tunnel excavation component 1;

[0035] A conveying assembly 2 is provided at one end of the excavation assembly 1 for conveying excavated soil and rocks;

[0036] A ventilation assembly 4 is provided at the bottom of the excavation assembly 1 for ventilating the excavation area;

[0037] The ventilation assembly 4 includes a support plate 41, which is combined with the driver 3 through a telescopic member, and an arc strip 414 is provided at the bottom of the support plate 41, and the arc strip 414 cooperates with the telescopic member to force the front end of the support plate 41 to fit the ground;

[0038] The inner side of the support plate 41 is provided with two symmetrically arranged inner cavities 413, and the top of the inner cavity 413 is provided with a guide impeller 42 for guiding the excavated gravel into the conveying assembly 2;

[0039] A ventilation area 43 is provided on the top of the guide vane 42 .

[0040] The support plate 41 is combined with the driver 3 through a telescopic member to ensure that the ventilation assembly 4 can adapt to different excavation environments. An arc strip 414 is provided at the bottom of the support plate 41, and the front end of the support plate 41 is fitted with the ground in cooperation with the telescopic member. The ventilation assembly 4 is provided at the bottom of the excavation assembly 1 to ventilate the excavation area and ensure the safety of the operating environment.

[0041] A ventilation area 43 is provided on the top of the guide impeller 42 to enhance the ventilation effect and keep the air in the excavation area fresh.

[0042] By designing the supporting plate 41 and the guide impeller 42 in a reasonable manner, the excavation area is ventilated and cleaned, and the safety and comfort of the working environment are improved. At the same time, the setting of the conveying component 2 also improves the efficiency and smooth progress of the excavation operation, and the ventilation component 4 ventilates the excavation area, reduces the accumulation of harmful gases, and ensures the safety of the environment.

[0043] Furthermore, a dust reduction measure, such as a liquid atomizer (generally water), may be provided at the front end of the tunneling assembly 1 to achieve a stable dust reduction environment, prevent dust from escaping, and ensure the tunneling working environment;

[0044] Moreover, the setting of the conveying component 2 realizes the timely conveying of excavated soil and rocks, and improves the efficiency of the excavation operation. Through the design of the guide impeller 42, the excavated gravel is introduced into the conveying component 2, which keeps the excavation site clean and reduces the pollution to the working environment. The support plate 41 is combined with the driver 3 through the telescopic part, and can adapt to different excavation environments, and has certain flexibility and adaptability.

The function of the diverter pipe 47 is to evenly distribute the wind force generated by the ventilation impeller 44 to various parts of the sealing plug 48, ensuring that the ventilation effect can fully cover the entire excavation area and further improve the ventilation effect. Through the design of the turbine fan 49 and the sealing plug 48, the working performance and stability of the ventilation component 4 are enhanced, making the ventilation system more reliable.
