The invention discloses x-ray detecting equipment. The x-ray detecting equipment comprises a feeding device, a discharging device, and a detecting device arranged between the feeding device and the discharging device. The feeding device comprises a box mechanism, and a feeding and conveying mechanism arranged on one side of the box mechanism. The feeding and conveying mechanism is used for conveying trays carrying materials in the box mechanism to the detecting device one by one. The detecting device comprises a detecting conveying mechanism, and an x-ray detecting mechanism arranged close tothe detecting conveying mechanism. The detecting conveying mechanism is used for conveying the trays carrying the materials to be detected to a detecting area of the x-ray detecting mechanism, and conveying the detected trays to the discharging device. The x-ray detecting equipment is reasonable in design, compact in overall structure, small in occupied area and high in protection equipment grade,the x-ray leakage amount can be effectively reduced, and the safety can be improved; and meanwhile the positions of an x-ray emitter and an x-ray receiver can be freely adjusted, material detection of different multiplying powers is achieved, the detecting efficiency is high, and detection is precise.
