The earth transport device of claim 1, wherein: a headstock baffle (5) is arranged between the two fixed side plates (2), and the headstock baffle (5) is fixed on one side, close to the headstock, of the hopper (1); a side plate overturning driving piece (33) for driving the movable side plate (3) to overturn is arranged between the headstock baffle (5) and the movable side plate (3).
4. The earth transport device of claim 1, wherein: one of the movable baffle (6) and the fixed side plate (2) is provided with a lock seat (63), and the other is provided with a lock piece (64); the locking piece (64) is matched with the locking seat (63).
5. A method of sand transportation using the earth transport device of claim 4, comprising the steps of: fixedly connecting the movable baffle (6) to the fixed side plate (2); the movable side plate (3) and the reinforcing cover plate (4) are driven to move towards the direction away from the car hopper (1), and an opening for sand to enter the car hopper (1) is formed; filling sand into the hopper (1) from the opening; the two movable side plates (3) are driven to move relatively and abut against each other, and the reinforcing cover plate (4) is driven to move towards the other movable side plate (3) until abutting against one side, far away from the car hopper (1), of the other movable side plate (3); the first air bag component (42) is controlled, so that the first air bag component (42) and the cover plate shielding part (41) which are positioned above the reinforcing cover plate (4) are filled in the gap between the reinforcing cover plate (4) and the movable side plate (3).
6. The sand transportation method of claim 5, further comprising unloading the earth material: releasing the lock seat (63) to separate the lock piece (64) from the lock seat (63) and discharge sand in the hopper (1) from between the movable baffle (6) and the two connecting plates (61); the first air bag component (42) is driven to deflate, so that the first air bag component (42) is contracted between the cover plate shielding part (41) and the reinforced cover plate (4).
