Lignite feeding device and stepping type lignite drying machine

The utility model provides a lignite feeding device and a stepping lignite dryer. The lignite feeding device comprises a belt weigher, a rotary discharger and a distributing device. The belt weigher is mounted on the rotary discharger, so that lignite is conveyed to a feeding hole of the rotary discharger; the rotary discharger is mounted on the dryer shell, and a discharge port of the rotary discharger is communicated with a feed port in the dryer shell; the material distributing device is installed in the dryer shell, and a plurality of corresponding material distributing channels are formed in the path of lignite falling from the rotary feeder to all grate beds in the grate bed device. The uniformity of a lignite material layer can be improved, so that the heat exchange efficiency is improved, and the system energy consumption, coal consumption and the probability of spontaneous combustion of lignite are reduced. 本发明提供了一种褐煤喂料装置及步进式褐煤烘干机，褐煤喂料装置包括皮带秤、回旋下料器和分料装置；所述皮带秤安装在所述回旋下料器上，从而将褐煤输送到所述回旋下料器的进料口中；所述回旋下料器安装
