For the transport of bulk material, such as stone dust, the conventional arrangement is a belt conveyor, one apparatus at a discharge point. In the whole material stacking process, the belt conveyor is used for conveying the bulk stone powder material to the cantilever belt conveyor from the tail car, and then the front end of the arm support is used for discharging the stone powder to a material yard in a throwing and discharging mode to finish material stacking.

At present, the applicant piles the mountain flour by adopting the above mode, namely, the mountain flour is conveyed to the transfer belt conveyor by the tail car, then the mountain flour is conveyed to the cantilever belt conveyor by the transfer belt conveyor, and finally the mountain flour drops from the discharge end of the cantilever belt conveyor to form a pile in a stock yard. However, since the height of the discharge end of the cantilever belt conveyor is limited, after the stacking is performed for a period of time, the top of the stack is increased to be as high as the discharge end of the cantilever belt conveyor, and at this time, the discharge of the cantilever belt conveyor is affected by the stack, and the stack needs to be transferred to other places of the yard by manpower or a transfer vehicle, and then the tail car, the transfer belt conveyor and the cantilever belt conveyor are started to continue stacking.

When the mode is adopted to stack the stone powder, the tail car, the transfer belt conveyor and the cantilever belt conveyor need to be stopped at intervals so as to transfer the material pile at the discharge end of the cantilever belt conveyor to other places of a stock yard through a manual or transfer vehicle, and then the vehicle, the transfer belt conveyor and the cantilever belt conveyor are started to continue stacking, so that the working efficiency of stone powder stacking is low, the labor intensity of workers is high, and the labor cost is high.

The transfer discharge hole 53 is arranged close to the right side wall 42 of the blanking box 5 (taking the visual angle of fig. 2 as a reference), so that when the blanking box 5 is transferred, stone powder can completely fall onto the second belt conveyor 3 through the transfer discharge hole 53, and the blockage caused by accumulation of the stone powder in the blanking box 5 is avoided. The blanking outlet 52 is provided with a blanking valve for controlling the opening and closing of the blanking outlet 52, and the transfer outlet 53 is provided with a transfer valve for controlling the opening and closing of the transfer outlet 53.

The specific implementation process is as follows:

before carrying out transport, windrow, control blanking valve earlier and open blanking discharge gate 52 to control the transfer valve and will transport discharge gate 53 and close, then start feeding car 1 and conveying mechanism, the mountain flour is carried to the discharge end of feeding car 1, drops to receiving mechanism 4 from the discharge end of feeding car 1, drops to the feed end of first band conveyer 2 from receiving mechanism 4 again, is carried by first band conveyer 2 continuation. Before the mountain flour falls to first band conveyer 2 from feed wagon 1, strike with buffer board 41 of receiving mechanism 4 earlier and subtract the trend to weaken the mountain flour and to the striking that the belt of first conveyer caused, delay the belt wearing and tearing of first band conveyer 2, increase of service life. In the process of impact of the stone powder and the buffer plate 41, the splashed stone powder is blocked by the side plates, so that the stone powder is prevented from falling to a non-stockpiling area of the stock yard.

The stone powder is carried to the discharge end from its feed end by first band conveyer 2, feed inlet 51 and blanking discharge gate 52 that loop through blanking case 5 drop to the subaerial of stock ground, the mountain flour piles up formation stockpile on the subaerial of stock ground gradually, when the height of stockpile top reaches the height of blanking case 5 bottom, the control blanking valve is closed the discharge gate, and control and transport the valve and will transport discharge gate 53 and open, the mountain flour loops through blanking case 5 feed inlet 51 and transports discharge gate 53 and drop to second band conveyer 3 this moment, carry out subsequent transport, the windrow. The scheme can realize the continuous conveying and stacking of the mountain flour, and is favorable for improving the stacking efficiency; and can set up blanking case 5 in presetting the windrow position for the stone powder carries and carries out the blanking when being carried to the anticipated position, avoids the trouble of artifical or transfer car transport, alleviates workman's intensity of labour, is favorable to controlling the cost of labor.
