The invention provides a self-discharging box body and a semitrailer. The self-discharging box body comprises an underframe, a lifting longitudinal beam, a plurality of pairs of telescopic beams and two bottom plates, the lifting longitudinal beam is positioned on the underframe; the two longitudinal ends of the lifting longitudinal beam can abut against the two longitudinal ends of the underframe. The telescopic beams are arranged at intervals in the longitudinal direction of the lifting longitudinal beam. Each pair of telescopic beams comprises telescopic beams which are respectively arranged on two transverse sides of the lifting longitudinal beams; one end of each telescopic beam is rotationally connected with the underframe, and the other end is rotationally connected with the lifting longitudinal beam; the two bottom plates are located on the bottom frame and arranged on the two opposite sides of the lifting longitudinal beam respectively. The lifting longitudinal beam can ascend and descend under the action of the lifting mechanism, then the telescopic beams are driven to stretch out and draw back, and the telescopic beams can incline downwards in the direction away from the lifting longitudinal beam. Goods are contained in the self-discharging box body, after the semitrailer arrives at a destination, the lifting rods move in the vertical direction to lift the lifting longitudinal beams, the lifting transverse beams on the two sides stretch out to form a triangular structure, and the goods are discharged out of the box body from the two sides of the box body.
本发明提供了一种自卸箱体及半挂车,包括底架、升降纵梁、多对伸缩梁及两底板;升降纵梁位于底架上;升降纵梁的纵向两端能够抵于底架纵向的两端;多对伸缩梁沿升降纵梁的纵向间隔设置;每对伸缩梁包括分列于升降纵梁横向两侧的伸缩梁;各伸缩梁的一端与底架转动连接,另一端与升降纵梁转动连接;两底板位于底架上并分列于升降纵梁的相对两侧;其中,升降纵梁能够在举升机构的作用下升降,进而带动各伸缩梁伸缩,且能够使伸缩梁沿远离升降纵梁的方向向下倾斜。自卸箱体内容置货物,当半挂车到达目的地后,升降杆沿竖向运动以抬起升降纵梁,两侧升降横梁伸出以形成三角形结构,货物自箱体两侧卸出箱体。
