摘要： A conveyor pan for a chain scraper conveyor comprises a bottom plate and a pair of side profiles fixed to the bottom plate by welding. The conveyor pan has an increased wear resistance, in particular due to a specific geometry of a weld groove formed between the profile rails of the side profile and the bottom plate. The weld groove extends deeper into each profile rail, resulting in a more durable weld connection during use of the conveyor pan. In addition, a geometry of a pocket member for connecting adjacent conveyor pans and an inspection opening formed in the bottom plate have also been improved to result in an increased strength of the conveyor pan.

摘要： A replaceable guide piece (10) for an extraction or coal plough (100) is provided. The replaceable guide piece (10) includes a generally U-shaped guide piece body (12) configured to be inserted into a guide claw (14) of the plough (100). A single recess (22) is formed in a central portion of a guide piece body (12) to extend at an angle (α) from an upper side of guide piece body (12) to a side surface of the same. A locking mechanism (24) is configured to engage with the single recess (22) to prevent movement of the guide piece (10) in the longitudinal direction after insertion of the guide piece (10) into the guide claw.

摘要： A plow bit for a bit holder including a recess of a mining plow is disclosed. The plow bit also has a bit shank configured to be inserted into the recess of the bit holder. The bit shank has a front shank face, which is concave. The bit shank also has a rear shank face disposed on an opposite side of the bit shank with respect to the front shank face. The bit shank further has a first lateral shank face connected to the front shank face and the rear shank face. The first lateral shank face includes a first groove extending from the front shank face in direction of the rear shank face. The groove receives a securing pin.
