The invention relates to the technical field of coal mine monitoring equipment and discloses coal mine monitoring equipment with a good dustproof effect. The coal mine monitoring equipment comprises amonitoring equipment body with a monitoring lens at the bottom. A supporting plate is fixedly connected to the vertical side wall of one side of the monitoring equipment body. A motor is installed onthe vertical side wall, located over the supporting plate, of the monitoring equipment body. A rotating shaft is connected to the output end of the motor through a coupling. The rotating shaft is fixedly sleeved with a first bevel gear and a second bevel gear. The second bevel gear is located at the side, away from the motor, of the first bevel gear. A first rotating rod and a second rotating rodare rotationally connected to the supporting plate by two bearings, and the bearings are fixedly arranged in the supporting plate. The second rotating rod is located on the side, away from the monitoring equipment body, of the first rotating rod. A third bevel gear engaged with the first bevel gear is fixedly connected to the upper end of the first rotating rod. A cleaning plate is connected to the lower end of the first rotating rod through a connecting mechanism. The coal mine monitoring equipment has the good dustproof effect.
