Abstract

The invention discloses a first conveyor and a tunnel boring machine. The first conveyor comprises a fixed groove, a swinging groove, a chain conveying mechanism, a driving device and a follow-up tensioning device, wherein the swinging groove is rotationally connected with the fixed groove; the chain conveying mechanism comprises a driving chain arranged in the extending direction of the fixed groove and the swinging groove and the driving device slidably connected to the swinging groove and used for driving the driving chain to rotate; and the follow-up tensioning device is connected with the driving device and can move along with swinging of the swinging groove so as to drive the driving device to dynamically adjust the tightness of the driving chain. The first conveyor provided by the invention can swing left and right, can be suitable for a material conveying form that a three-conveying belt of a roadway is hung on a left hole wall or a right hole wall, and ensures that the whole driving chain keeps the same tightness in the swinging process of the swinging groove.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a first conveyor and an excavation machine. Background technique [0002] The roadheader is a commonly used equipment for underground operations. When the coal mine is working normally, the coal in front of the roadheader is brought into the first conveyor of the roadheader by the star wheel crawler, and then transported by the first conveyor to the back of the roadheader. On the overlapped second belt conveyor, the second belt conveyor is lifted up and then connected with the third belt conveyor, dump truck, shuttle car, etc. behind, and the materials continue to be transported to the rear. [0003] The traditional first conveyor does not swing its tail, and the discharge port of the traditional first conveyor is fixed, so it cannot be applied to the material transportation form in which the three-way belt is hung on the left or right wall of the tunnel.
