The present invention relates to a device to open and close a hopper for a vehicle, including: a storage unit where minerals supplied through a vehicle are stored; a screening unit mounted on top of the storage unit, while having a grid shape; a door unit mounted on the screening unit, with the ability to rotate, and to open and close the storage unit; a driving unit to rotate the door unit; and a sensor unit connected to the driving unit to sense the location of the vehicle to provide power to the driving unit. When the vehicle is sensed, the storage unit is automatically opened and closed when the vehicle leaves. Thereby, the scattering of minerals can be prevented. |
