[0002] In recent years, roadheaders with functions of tunneling, anchoring and shotcreting have been successively used in coal mine tunneling faces for roadway tunneling work. In the existing technology, the anchoring and shotcreting device of the roadheader is separately arranged relative to the roadheader body, and has basically no influence on the installation space of the middle conveyor on the body. Therefore, the middle conveyor in the existing technology usually uses front and rear connecting plates to connect the front and rear chutes of the middle conveyor.

[0003] However, for the front and rear chutes connected by the above connection structure, the size at the connection is too large. For the new roadheader-anchoring-shotcreting machine with anchoring and shotcreting parts installed on both sides of the body part, the space reserved on the body part for installing the middle conveyor is relatively small. Therefore, the front and rear chute structures connected by the above method cannot be installed on the roadheader-anchoring-shotcreting machine with anchoring and shotcreting parts installed on both sides. Therefore, there is an urgent need in the art for a front and rear chute structure for a roadheader-anchoring-shotcreting machine that can be used for the machine with anchoring and shotcreting parts installed on both sides of its body part and leaves a relatively small space for installing the middle conveyor. Summary of the Invention
