The invention discloses a transfer trolley used for stacking and destacking of bagged materials. The transfer trolley used for stacking and destacking of the bagged materials comprises a trolley frame, a fork plate, a trolley wheel connecting rod and two trolley wheels, wherein the two trolley wheels are connected through a wheel shaft, the lower end of the trolley frame is connected with one end of the fork plate in a rotating mode through a fork plate rotary pin, one end of the trolley wheel connecting rod is connected with the lower end of the trolley frame in a rotating mode through a connecting rod rotary pin, the other end of the trolley wheel connecting rod is connected with the wheel shaft in a rotating mode, the fork plate rotary pin and the connecting rod rotary pin are both parallel to the wheel shaft, the trolley frame is provided with an overturning loading station and a transportation station, the included angle between the overturning loading station and the fork plate is an acute angle, the included angle between the transportation station and the fork plate is 90 degrees, a first limiting and stopping structure and a second limiting and stopping structure are arranged between the trolley frame and the fork plate, the first limiting and stopping structure is used for enabling the trolley frame to rotate anticlockwise with the fork plate rotary pin as the axis to be positioned at the overturning loading station, and the second limiting and stopping structure is used for enabling the trolley frame to rotate clockwise with the fork plate rotary pin as the axis to be positioned at the transportation station. The transfer trolley used for stacking and destacking of the bagged materials has the advantages that the problem that a vehicle frame of an ordinary transportation vehicle can tip forwards easily during unloading, using is convenient and flexible, operation is safe, workload can be relived, and production efficiency is improved.
