The invention discloses a direct-drive scraping plate conveying device and relates to the field of material conveying. The device comprises a base and a chute, wherein a scraping plate is arranged in the chute; the scraping plate is fixed with a scraping plate suspending beam; a power device and a brake are arranged between the scraping plate suspending beam and the base; the power device is a linear motor; and a positioning mechanism is arranged between the scraping plate suspending beam and the base. In the device, a linear motor serves as a power source and secondary back irons are connected by interlinking pieces, so as to realize the horizontal turning, slope climbing and downhill motion of a conveyer; the secondary sides are independent of one another and can supply power by section, the number of the motors are determined by the size of a load, and the effect of high efficiency and energy conservation are achieved; and middle transmission mechanism such as couplers and roller wheels are not required, and the structure is simple.
