[0026] like Figure 1As shown, the first aspect of the embodiment of the present disclosure provides an angle-adaptive belt conveyor receiving part, which is installed on the belt conveyor and is used to receive materials from the tunnel boring machine; the belt conveyor receiving part includes a telescopic frame 1, a connecting frame 2, a roller plate assembly 4 and an adjustment assembly 3.

[0027] The front end of the telescopic frame 1 is fixedly mounted on the belt conveyor; the connecting frame 2 is mounted on the telescopic frame 1 and connected to the tunnel boring machine; the rear end of the roller plate assembly 4 is rotatably mounted on the rear end of the telescopic frame 1; the adjustment assembly 3 is installed between the roller plate assembly 4 and the belt conveyor, and is used to adaptively adjust the angle of the roller plate assembly 4.

[0028] The design of the telescopic frame 1 allows it to be extended and retracted accordingly according to the forward or backward movement of the tunnel boring machine, thereby adapting to the material transportation needs of the tunnel boring machine in different working stages; and the extension and retraction of the telescopic frame 1 also causes relative movement between the roller plate assembly 4 and the belt conveyor, thereby providing power for the adjustment assembly 3 to adaptively adjust the angle of the roller plate assembly 4, thereby ensuring the fit between the conveyor belt and the roller plate assembly 4, avoiding tearing of the conveyor belt due to the ribbon, and increasing the service life of the conveyor belt.

[0029] As an optional embodiment, the adjustment assembly 3 includes a track member and a moving member, one of which is mounted on the roller plate assembly 4, and the other of which is mounted on the belt conveyor; wherein the moving member can move along the track member, and along the front-back direction, the extension direction of the track member gradually approaches or moves away from the roller plate assembly 4, so that the roller plate can rotate adaptively during the extension and retraction of the telescopic frame 1. Through the design of the track member and the moving member, the roller plate assembly 4 can rotate adaptively during the extension and retraction of the telescopic frame 1, further enhancing the adaptability of the receiving part to different conveying angles and improving the stability and service life of the conveyor belt.

[0030] As an optional embodiment, the adjustment assembly 3 further includes an adjustment frame 31; the adjustment frame 31 is fixedly connected to the roller plate assembly 4; and the moving member is a roller and is rotatably mounted on the adjustment frame 31.
