[0009] The weight roller is fixedly connected to the portion of the tensioning belt located inside the sealed shell, and is suspended above the weighing sensor inside the sealed calibration coal feeder body through the tensioning belt.

[0010] In one possible implementation, the sealed calibration coal feeder further includes: a slide rail; the slide rail is located inside the sealed shell and is fixedly arranged on one side of the weighing sensor, and the weight roller has a slider at one end close to the slide rail, and the slider is slidably clamped in the slide rail.

[0011] In a possible implementation, the sealing shell has a fixing block on a side close to the belt winch, and the tensioning belt passes through the sealing shell and is fixedly connected to the fixing block.

[0012] In a possible implementation, the sealed calibration coal feeder further includes: a motor, wherein the motor is disposed outside the sealed shell, and an output end of the motor is fixedly connected to the belt winch shaft for driving the belt winch to rotate.

[0013] The beneficial effects of the present application are: the sealed calibration coal feeder of the present application can realize the sealing calibration of the coal feeder, and the weight roller is controlled by the belt winch to move up and down, avoiding the opening of the inspection port to cause a large amount of dust to rush out in the hot air.
