The invention discloses a material bin for a deep-sea mining vehicle and the deep-sea mining vehicle to solve the existing technical problem that during slipping, the deep-sea mining vehicle cannot relieve or eliminate the slipping state by controlling the weight of the material bin. The material bin comprises a material bin main body, a feeding port and a material bin controlling and dischargingdevice. The material bin controlling and discharging device comprises a discharging door and a discharging door controlling device, and the discharging door is located on the material bin main body which is opposite to the feeding port. The edge, away from the ground, of the discharging door is connected with the material bin main body through a hinge, and the edge, close to the ground, of the discharging door is connected with the discharging door controlling device to open and close the discharging door.
