Material screening device with inclined screen

The invention discloses a material screening device with an inclined screen, and belongs to the field of screening devices. The material screening device with the inclined screen is simple in structure, small in size, high in screening efficiency, easy to operate and convenient to manufacture. The problems that in an analysis sample screening device, screen holes are prone to blockage and deformation, and a machine is heavy are solved. By means of the technical scheme, the material screening device with the inclined screen comprises a bottom plate, a plurality of stand columns are fixedly arranged on the bottom plate, the tops of the stand columns are connected with a screen cover through springs, and the screen cover is provided with a feeding port; the lower portion of the feeding port communicates with the inclined screen, and the feeding port is located in one side of the highest end of the screen; the screen is fixed through a fixing supporting mechanism, a plurality of discharge ports are formed in the screen at intervals, and the discharge ends of the multiple discharge ports are located on the same side and located at the lowest end of the screen; and a power mechanism is arranged at the bottom of the inclined screen.
