Ore stock bin of deep-sea mining vehicle and metering method

The invention relates to the technical field of underwater weighing, and discloses an ore bin of a deep-sea mining vehicle and a metering method. The deep-sea mining vehicle ore bin is arranged at the tail part of the seabed mining vehicle and comprises an ore storage bin, a deep-sea weighing sensor, a video auxiliary alarm camera, a transmission pressure-resistant bin for data processing and a sensor mounting frame; the sensor mounting frame is a part of a vehicle body main frame of the seabed mining vehicle, the sensor mounting frame is connected with the ore storage bin through the deep sea weighing sensor, the video auxiliary alarm camera is arranged on the sensor mounting frame and faces the ore storage bin, and the deep sea weighing sensor is further connected with the transmission pressure-resistant cabin. The weight of the ore in the ore storage bin is measured in real time through the deep sea weighing sensor and the ore storage bin, and the problem that the ore cannot be weighed in real time through
