the vibration screening mechanism is formed by combining a first damping spring F41, a second damping spring F42, a screening hopper plate F1, a first side material baffle, a second side material baffle F2, a first material guide plate, a second material guide plate F3 and a vibration motor F5;

the top surface of the square frame is provided with a generator C.

When the discharging output device is in a closed state, the vibrating motor F5 can enable the vibrating screening mechanism to vibrate after being started, a ballast digging bucket of the ballast changer can pour old ballast onto a screening bucket plate in the vibrating state, qualified large-particle ballast is intercepted by the screening bucket plate F1 and is refilled to the middle of a track through a discharging bucket frame E2 so as to achieve the purpose of recycling, unqualified small-particle ballast falls into a collecting bucket frame E1 through meshes of the screening bucket plate F1, and after the collecting bucket frame E1 is filled with the small-particle ballast, the self-walking servo motor is started and drives the rolling track mechanism to walk, so that the whole machine is controlled to move to a designated discharging place along a railway track;

the hook D9 is unfastened, so that the lifting mechanism is turned 90 degrees counterclockwise, at the moment, the discharging output device is in an open state, small-particle ballast stones falling into the aggregate hopper frame E1 fall to the upper surface of the conveying belt D7 through the rectangular blanking port in the bottom surface of the aggregate hopper frame E1, the discharging inserting plate of the aggregate hopper frame E1 is pulled upwards to open the discharging port of the aggregate hopper frame E1, the discharging motor D1 drives the discharging output device to operate through the speed reducer, the driving chain wheel and the transmission chain D2 after being started, and the conveying belt D7 in operation conveys the small-particle ballast stones to a specified discharging place.
