Weighing coal feeder

The invention provides a weighing coal feeder, and relates to the field of metering feeding equipment. The weighing coal feeder comprises a shell, wherein a roller and a conveyor belt driven by a motor are arranged in the shell; a weighing roller is arranged below the conveyor belt; a first through hole and a second through hole are formed in the surface of the shell; a first pressing part and a second pressing part passing through the first through hole and the second through hole are arranged at two ends of the weighing roller. The weighing coal feeder further comprises a first support, a second support, a first weighing sensor and a second weighing sensor; the first pressing part is arranged above the first weighing sensor to be connected with the first weighing sensor; the second pressing part is arranged above the second weighing sensor to be connected with the second weighing sensor; the first support is arranged below the first weighing sensor to be connected with the first weighing sensor; the second support is arranged below the second weighing sensor to be connected with the second weighing sensor. The weighing sensors are arranged outside the shell, so that accurate metering of the weighing sensors is guaranteed, and the weighing sensors are unlikely to be smashed by running-off materials.
