Chassis with five-wheel or Fukuda, liberation and other vehicle chassis transmission and dispensing power from the hydraulic pump; hydraulic pump directly from the engine body, to avoid the power from the gearbox by the clutch, because the ration contains many long crude fiber, it is easy to jam and jam. Therefore, the use of stirrers in the material transmission mode of the box not only improves the reliability of the equipment, solves the high failure rate caused by a large number of parts, but also improves the uniformity of the exit of the equipment for material withdrawal by installing a belt conveyor, the Q345B 16 manganese steel plate can be used for both sides of the material spreading box, and the parts can be made by NC cutting and bending to ensure the uniform standard of the parts
