Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of underground mining equipment, and in particular relates to a telescopic machine body and belt conveyor. BACKGROUND

[0002] In underground mining operations, the coal mined by the mining machine is continuously transported to the crossheading belt conveyor connected behind the self-moving machine tail through the working face conveyor, the crusher, the bridge-type transfer machine and the belt conveyor. The self-moving machine tail of the belt conveyor is a supporting device for the roadway transportation of the fully-mechanized coal mining face. It is very important as an intermediate connecting device of the belt conveyor and the bridge-type transfer machine. It should be suitable for high yield and high efficiency and meet the needs of rapid advancement. It also has the functions of adjusting the deviation of the rubber belt, adjusting the height, correcting the direction of the transfer machine and moving forward automatically, etc., to ensure the smoothness and connection of the crossheading transfer.

[0003] However, the existing telescopic machine body design, i.e. the scissors arm method, still has some deficiencies in actual application. During the stretching process, the scissors arm structure is prone to tilting or even falling due to uneven stress, which undoubtedly poses a potential threat to the safety and stability of the mining operation. In addition, the space occupied by the telescopic machine body when it is expanded or retracted on the guide rail is relatively large, which is undoubtedly a problem that cannot be ignored in the limited underground environment. Therefore, it is necessary to improve. UTILITY MODEL CONTENT
