The invention discloses a self-unloading carrying trolley. The self-unloading carrying trolley comprises a trolley frame, two vertical beams, an upper support, a lifting device and an unloading rolling wheel mechanism. The two vertical beams are fixed to the two sides of the end of the trolley frame respectively; the upper support is located on the two vertical beams and fixed together with the two vertical beams; the lifting device is fixed to the upper support; one end of the unloading rolling wheel mechanism is in sliding joint with the trolley frame, the other end of the unloading rolling wheel mechanism is connected with the lifting device, and the unloading rolling wheel mechanism can be pulled by the lifting device to tilt and ascend. The self-unloading carrying trolley is provided with the unloading rolling wheel mechanism and a driving motor. During unloading, a rolling wheel support is lifted, automatic unloading of goods on unloading rolling wheels is achieved through gravity of the goods, and manpower is reduced during unloading. The driving motor can drive the self-unloading trolley to move forwards, so that the automatic carrying process without manpower is achieved and the carrying efficiency is greatly improved.
