When the vehicle is turned over and unloaded, the movable cover plate 120 rotates to be opened under the action of the gravity of the shot particles, so that the shot particles can be scattered from the opening position of the movable cover plate 120, and the unloading is completed. Because of the limited width of the gap between the side sill 130 of the movable roof 100 and the side wall of the cargo box, the discharge rate is slow only through the gap. The movable cover plate 120 is arranged on the movable top cover 100, and the movable cover plate 120 is opened during unloading, so that most of the area on the movable top cover 100 can be unloaded, and the unloading speed is increased.
Preferably, the end of the movable cover plate 120 far away from the rotation connection part is provided with a mounting edge, the main beam and the variable of the movable top cover 100 are provided with mounting grooves, and the mounting edge can be clamped in the mounting grooves. Because the movable cover plate 120 can rotate, when the open wagon normally operates, the movable cover plate 120 needs to be prevented from being opened in a part of the area due to accidental rotation, the movable cover plate 120 is provided with a mounting edge at one end far away from a rotating joint of the movable cover plate 120, mounting grooves are formed in the main beam and the side beams 130, the movable cover plate 120 can be fixedly clamped on the movable cover plate 100 through the mounting edge and the mounting grooves, the movable cover plate 120 can be prevented from being opened due to accidental rotation, during dumping, the movable cover plate 120 is impacted by the shot particles under the action of impact force, the mounting edge on the movable cover plate 120 can be separated from the mounting grooves due to the large gravity of the shot particles, the movable cover plate 120 can be further rotated freely, and the shot particles are scattered from the opening of the movable cover plate 120, so that dumping is completed.
Preferably, a torsion spring is provided at the rotational connection of the movable cover 120 and the movable top cover 100. Because the movable cover 120 can rotate, when the open wagon normally operates, the movable cover 120 needs to be prevented from opening the partial area of the movable top cover 100 due to accidental rotation, and a torsion spring is arranged at the rotating connection position, so that the movable cover 120 is in a closed state or has a tendency of rotating to the closed state under the action of the torsion spring. When the vehicle is turned over and unloaded, the movable cover plate 120 is impacted by the shot particles under the action of impact force, the movable cover plate 120 rotates to be opened due to the fact that the gravity of the shot particles is larger than the force of the torsion spring, and after the unloading is completed, the movable cover plate 120 is restored to a closed state under the action of the torsion spring.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
