3. The hopper car body of claim 2, wherein first striker plates are arranged on two sides of the inner bottom plate and extend upwards from the surface of the inner bottom plate.

4. The hopper car body according to claim 2, characterized in that the side of said inner floor is provided with a first guide and/or the side of said inner end plate is provided with a first guide; and a second guide part matched with the first guide part is arranged on the side part of the outer end wall, and the second guide part is an arc-shaped section taking the rotating shaft as the circle center.

5. The hopper car body of claim 2, further comprising a stop located at a side of said fixed-capacity car body or a side of an outer headwall; when the inner end wall is located at the unloading position, the inner end wall is in interference fit with the limiting piece.

6. The hopper car body according to claim 5, wherein the limiting member comprises a fixed plate and a limiting plate connected with the fixed plate, the limiting plate extends from the fixed plate to a direction intersecting with the plate surface of the fixed plate, and the fixed plate is fixed on the side of the fixed-capacity car body or the side of the outer-layer end wall;

the locating parts are at least two, and the at least two locating parts are respectively arranged on two sides of the solid-containing vehicle body or two sides of the outer end wall.

7. The hopper car body according to any of claims 1 to 6, wherein the bottom of said fixed-capacity car is provided with a discharge port; and a material guide plate is arranged in the accommodating cavity, is obliquely arranged from the unloading opening to the direction of the inner-layer end wall and is butted with the bottom of the inner-layer end wall.

8. The hopper car body as claimed in claim 7, wherein said guide plate is provided with second baffle plates at both sides thereof, said second baffle plates extending upward from the plate surface of said guide plate.

9. The hopper car body of any one of claims 1 to 6 further comprising a drive mechanism drivingly connected to said inner end wall, said drive mechanism being capable of moving said inner end wall from said expanded position to said discharge position and moving said inner end wall from said discharge position to said expanded position.
