The invention provides multi-stage material conveying equipment which comprises two material conveying devices, brackets and weight induction devices; each material conveying device comprises a material barrel, a feeding hole formed in the side wall of the material barrel and a discharge hole formed in the bottom of the material barrel; the discharge hole of one material conveying device communicates with the feeding hole of the other material conveying device through a connection pipeline; the material barrels of the material conveying devices are installed on the corresponding brackets; andeach weight induction device is arranged between the corresponding bracket and the corresponding material barrel to be used for detecting a weight of the corresponding material conveying device. According to the technical scheme of the embodiment of the invention, by arranging the brackets to support the material conveying devices respectively and arranging the weight induction devices between thebrackets and the corresponding material barrels of the material conveying devices, the weights of the material conveying devices can be accurately measured, so that the flow rates and the flow velocities of feeding and discharging are controlled, and the multi-stage material conveying equipment can perform accurate conveying on materials.
