Problems solved by technology

[0003] However, at present, the belt conveyors used for tunnel boring machines basically have a fixed length in the direction of excavation and cannot be stretched.
Therefore, the structure of the belt conveyor is relatively heavy, and it has poor flexibility when cooperating with other devices or components.
This can be inconvenient, for example, when inspections, cutterhead repairs, etc. are required

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] figure 1 The structure of the belt conveyor 100 according to the present invention is schematically shown. The belt conveyor 100 includes a base body 12 and an end portion, wherein the base body 12 is relatively fixed. The end portion comprises a drum 1 which is surrounded by a conveyor belt 17 and which can be turned there. The end portion may also include a slag receiving hopper 2 and a material receiving section 3, which are well known to those skilled in the art and will not be described in detail here.

[0024] for figure 1 For example, the left side is the front and the right side is the rear. The terminal portion is located in front of the base body 12 .

[0025] The belt conveyor 100 also includes a telescopic mechanism connected between the base body and the end portion and configured to enable the end portion to move forward and backward relative to th...

Abstract

The invention relates to a belt conveyor. The belt conveyor comprises a fixed base body, a tail end part and an extending-and-contracting mechanism. The tail end part comprises a drum and a conveyor belt surrounding the drum and is located in front of the base body. The extending-and-contracting mechanism is connected between the base body and the tail end part. The tail end part can move in an extending-and-contracting manner relative to the base body through the extending-and-contracting mechanism. The belt conveyor is high in flexibility.

Description

technical field [0001] The invention relates to the technical field of conveying, in particular to a belt conveyor. Background technique [0002] Belt conveyor is a kind of continuous transportation equipment, which can be used in tunnel excavation projects together with roadheaders, especially large-scale and long-distance tunnel excavation projects. [0003] However, at present, the belt conveyors used in tunnel boring machines basically have a fixed length in the direction of excavation and cannot be stretched. Therefore, the structure of the belt conveyor is cumbersome and less flexible when cooperating with other devices or components. This can be inconvenient, for example, when inspections, cutterhead repairs, etc. are required. [0004] Therefore, a belt conveyor with high flexibility is required. Contents of the invention [0005] In view of the above problems, the present invention proposes a belt conveyor, which has high flexibility. [0006] The present inve...
