Quantitative fly ash conveyor

The invention discloses a fly ash quantitative conveyor, relates to the technical field of fly ash conveying, and aims to solve the problems that in the prior art, fly ash is mostly quantitatively conveyed through an auger disc, the conveying amount completely depends on the rotating speed of the auger disc, quantitative and fixed-batch conveying cannot be achieved, and quantification is not accurate enough. A material blocking pipe, a connecting pipe and a feeding pipe are arranged between the first-stage conveyor and the second-stage conveyor, the first-stage conveyor and the second-stage conveyor are communicated through the material blocking pipe, the connecting pipe and the feeding pipe, and a quantitative adjusting cylinder is rotationally connected into the second-stage conveyor. A first trough, a second trough, a third trough, a fourth trough, a fifth trough and a fifth trough are respectively arranged on the quantitative adjusting cylinder, the spaces in the first trough, the second trough, the third
