It has piled material and material two working modes. The bulk material transported by belt conveyor is unloaded to the belt conveyor on the arm frame, which is thrown from the front end of the boom. Through the operation of the whole machine, the rotation of the arm frame and the pitch can make the material stack to form a trapezoidal cross section. Is realized through continuous reclaimer boom and bucket wheel rotating rotary. Plate unloading materials are disposed to reverse the running boom of belt conveyor, then the machine center located below the hopper unloading to the material field of belt conveyor. Through the operation of the whole machine, the rotation of the arm frame, the pitch, can make the bucket wheel will be the material of the storage stack.
