Beschreibung
Zusammenfassung:	The utility model discloses a flue gas collecting and sampling device which comprises a collecting box, supporting plates are fixedly connected to the top and the bottom of the collecting box, rotating columns are rotationally connected to the inner sides of the two supporting plates, a gas collecting cylinder is fixedly connected between the two rotating columns, a rotating mechanism is arranged in one supporting plate, and a gas collecting cylinder is arranged in the other supporting plate. The device has the advantages that the rotating mechanism is additionally arranged, the reciprocating lead screw rotates to drive the sliding block and the rack to move in a reciprocating mode, and therefore the rack drives the gear and the rotating rod to rotate in a reciprocating mode; the rotating rod drives the rotating column and the gas collecting cylinder to perform reciprocating fixed-angle rotation treatment and uniform sampling treatment, and a scraping plate is additionally arranged, so that the rotating rod d
