Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-7, a novel derailleur limiting device comprises a scraper conveyor mounting frame 1, a middle plate 2 is fixedly arranged at the bottom of the scraper conveyor mounting frame 1, a tongue plate 3 is detachably and fixedly arranged at the upper part of the scraper conveyor mounting frame 1, a limiting seat 4 is arranged between the middle plate 2 and the tongue plate 3, and a limiting groove 41 is arranged on the limiting seat 4; a connecting seat 51 of the derailleur 5 is vertically inserted in the limiting groove 41 in a matching manner; the lower part of the limiting seat 4 is vertically inserted into the mounting groove 21 of the middle plate 2, and the other side of the limiting seat 4, which is far away from the derailleur 5, is abutted against the end part of the scraper conveyor mounting frame 1 for limiting; the lower portion of the tongue plate 3 is provided with a limit boss 31, and the upper portion of the middle plate 2 and the upper portion of the coupling seat 51 of the derailleur 5 are restrained between the limit boss 31 and the end of the scraper conveyor mounting frame 1.
