The generator 3 is connected to the diesel engine 4 through a first belt 10. The generator 3 is electrically connected to a control cabinet 27. The control cabinet is arranged on the first frame and is located on one side of the generator. The control cabinet divides the power generated by the generator into Allocate to other power-demanding equipment; the jaw crusher 5 is connected to the diesel engine 4 through the second belt 11, the vibrating feeder 6 is arranged at the top of the first frame 1 near the end of the second frame 2 through the rotating mechanism 9, and the outlet of the vibrating feeder can selectively correspond to the jaw crusher inlet or the belt conveyor through the rotating mechanism; the vibrating screen 8 is tiltedly arranged on the second frame 2, and the lower end away from the first frame 1 is the discharge port, and the belt conveyor 7 is arranged on the first frame 1, and one end is located below the outlet of the jaw crusher 5, and the other end is located above the second frame 2, corresponding to the high end of the vibrating screen 8. The stone falls on the vibrating feeder, and the vibrating feeder conveys the stone to the jaw crusher. After the jaw crusher crushes the stone, it falls to the belt conveyor through the lower outlet, and the belt conveyor conveys the stone to the vibrating screen for vibration screening. When single crushing is required, the second frame is dismantled and moved away. At this time, the crushed stone is transported to the ground via the belt conveyor; when single screening is required, the vibrating feeder is controlled by the rotating mechanism so that its outlet corresponds to the top of the belt conveyor. The stone is output from the vibrating feeder and falls onto the belt conveyor. The belt conveyor transports the stone to the vibrating screen for vibration screening.

[0026] In this embodiment, the generator, diesel engine, jaw crusher, vibrating feeder, belt conveyor, and vibrating screen all adopt existing technology products. Among them, the vibrating feeder is driven by a vibrating motor, and the power of the vibrating motor is provided by the generator driven by the diesel engine. The vibrating screen is driven by the motor pulling the pulley to drive the rotating shaft to rotate.
