CONVEYOR FOR TRANSPORTING MATERIALS AND TUNNELING MACHINE Russian patent published in 2024 - IPC E21C35/20 E21C35/12 E21F13/02 

FIELD: tunneling machines.

SUBSTANCE: tunneling machine includes a vehicle body equipped with a rear support structure at the rear, a transport body provided on the vehicle body, and a conveyor. The conveyor includes a first grooved body configured to be coupled to a transport body of a tunneling machine, a second grooved body provided at a rear end of the first grooved body and rotatably connected to the transport body, and a lifting mechanism provided under the second grooved body and used to drive into the movement of the second grooved body to perform lifting/lowering. The rear end of the first grooved body is provided with a first connecting structure. The front end of the second grooved body is provided with a second connecting structure that interacts with the first connecting structure, and the second connecting structure is rotatable relative to the first connecting structure, the first connecting structure is an arcuate recess and is provided in the rear end surfaces of the two first side plates of the first grooved body. The second connecting structure is an arcuate projection provided on the front end surfaces of the two second side plates of the second grooved body and accordingly extends into the arcuate recess on the same side. The sections on the front end surfaces of the second side plates above and below the arcuate recess are respectively inclined toward the rear end of the second grooved body. The first grooved conveyor body is rigidly connected to the transport body, the second grooved conveyor body is rotatably connected to the transport body, and the conveyor lifting mechanism is rotatably provided on the rear support structure.

EFFECT: adaptability of the tunneling machine to various working sites.
