Abstract: The present invention provides a method for detecting Brucella infection, i.e., a serum and blood cell synchronous detection method. The detection method comprises two operation steps of serum sample detection and living blood cell sample detection and uses a supporting kit. The kit can be used for pretreatment of blood samples for clinically detecting Brucella in vitro. The serum and blood cell synchronous detection method can be used for early clinical rapid diagnosis of Brucella infection and medication guidance in the treatment process, and can also be used for prognosis, epidemiological survey of brucellosis, etc. The present invention can also be used for early clinical rapid diagnosis of other intracellular parasitic infection.

Abstract: An elastic self-positioning pre-dicing device and method, the device includes a V-shaped self-positioning device, a cutter and a separation device; the V-shaped self-positioning device includes first and second elastic conveying faces which form a V-shaped conveying space, and materials are kept in a vertical state when arriving at a bottom end between the two elastic conveying faces with the conveying of the faces; the cutter is arranged at the bottom end between the two faces to cut the materials in half along a long axis; and the separation device is arranged at the lower part of the cutter and configured to convey the materials cut in half to next stage respectively. This overcomes the defects of low efficiency in manual dicing of seed potatoes and waste of seed potatoes. The half-cut seed potatoes will be conveyed to next intelligent dice identification station to ensure high utilization of seed potato production.

Abstract: A conical self-positioning limit feeding device and method. The conical self-positioning limit feeding device has bearing pot, empty circle in the center of bearing pot, U-shaped slide way formed between outer circle and inner circle, rotating evacuation cone and limit feeding rod arranged in the bearing pot and rotate in the same direction, and the speed of the rotating evacuation cone is greater than that of the limit feeding rod; materials are placed in the bearing pot, the evacuation cone rotates, and the materials rotate in the U-shaped slide way of the bearing pot by the torque generated by the friction between rotating evacuation cone and materials, till the long axes of the materials are tangent to the radius of the rotating evacuation cone; the limit feeding rod rotates and pushes materials to exit at equal intervals, thereby achieving the arrangement of the materials in the direction of long axis.
