The invention discloses a coal blockage detection method and device and a coal conveying device. The coal blockage detection method comprises the steps that a detection pulling piece arranged below amaterial outlet of a hopper is driven by a drive assembly to sweep over the portion below the material outlet, and whether coal blockage occurs or not is judged by detecting whether the drive assemblycan normally complete the drive stroke or not. The coal blockage detection method and device and the coal conveying device have the advantages that accuracy and reliability are high, the situation that coal samples influence normal work of equipment and damage detection equipment can be effectively prevented, the service life of the equipment is prolonged, and cross contamination of the coal samples can be effectively prevented. 本发明公开了种堵煤检测方法、装置及煤料传送装置，堵煤检测方法包括：设置在料斗出料口下方的检测拨片，在驱动组件的带动下从所述出料口的下方扫过，通过检测所述驱动组件能否正常完成驱动行程判断是否发生堵煤。本发明具有准确性高，可靠性高，可有效防止煤样影响设备正常工作，损坏检测设备，提高设备的使用寿命，可有效防止煤样交叉污染等优点。
