It also includes a frame and a weighing sensor. The scraper conveyor is arranged above the frame, and the weighing sensor is arranged between the scraper conveyor and the frame and connects the scraper conveyor and the frame. Since the plant-mixed hot regeneration equipment is equipped with the above-mentioned hot regeneration material metering and conveying device, the overall height of the plant-mixed hot regeneration equipment is greatly reduced, the cost is reduced, and the structure is simplified; in addition, the scraper in the hot regeneration material metering and conveying device is not easily corroded and does not need to be replaced frequently, saving costs.
