Raw material transportation method, device and system

The invention provides a raw material transportation method, device and system. The raw material transportation method comprises the steps that the unloading completion moment when the total unloading weight of target raw materials reaches the target weight is obtained; the first conveying time when the raw materials are conveyed to the intermediate bin from the cut-off raw material scale hopper is calculated, the cut-off raw material scale hopper represents the raw material scale hopper corresponding to the unloading completion moment, and the closing moment of the bin door of the intermediate bin is obtained according to the unloading completion moment and the first conveying time. According to the technical scheme, the accurate closing time of the bin door of the intermediate bin is obtained by accurately obtaining the unloading completion time and calculating the conveying time of the raw materials, so that the closing time of the bin door is not easily influenced by factors such as experience of operator
