A threaded column 12 is fixedly connected to the output shaft of the machine 11, one end of the threaded column 12 is fixedly connected to a rotating shaft 16, a bearing 17 is sleeved on the surface of the rotating shaft 16, a fixed plate 19 is fixedly connected to the surface of the bearing 17, and a threaded tube 14 is threadedly connected to the surface of the threaded column 12. By setting the filter 6, the conveying mechanism 2, the motor 11, the threaded column 12, the threaded tube 14 and the collecting box 7, in actual applications, through the cooperation among the above, the screened materials can be fully automatically transported, and screened and graded layer by layer, so that the screened materials stay in different screen areas, so that the screened materials are divided into four categories, which is convenient for the later processing of the screened materials, while reducing human participation, reducing the labor intensity of the staff, and greatly improving the work efficiency.

[0019] Specifically, the inclined plate 4 is overlapped on the surface of the supporting plate 3 , the fixed plate 19 is fixedly connected to the upper surface of the extending plate 9 , and the threaded tube 14 is fixedly connected to the inside of the movable plate 15 .

[0020] Specifically, the number of the support plates 3, the inclined plates 4 and the filter screens 6 are three, and the three support plates 3, the inclined plates 4 and the filter screens 6 are arranged in parallel inside the frame 1, and the hole diameters of the three filter screens 6 are gradually reduced from top to bottom.

[0021] Specifically, the movable plate 15 is overlapped on the upper surface of the extension plate 9 , and the collection box 7 is arranged directly below the support plate 3 .

[0022] The working principle of the utility model is:

[0023] S1. When the device is in use, first place the material to be screened on the surface of the conveying mechanism 2, then start the transmission mechanism, send the screened material to the inclined plate 4 and the filter screen 6, then start the motor 11, the motor 11 drives the threaded column 12 to rotate inside the threaded tube 14, and the shaft 16 rotates inside the bearing 17 accordingly. The threaded tube 14 drives the movable plate 15 to move left and right as the threaded column 12 rotates, and the movable plate 15 drives the support plate 3 to slide left and right, and the slider 18 slides inside the slide groove 13 accordingly, thereby ensuring that the support plate 3 is in the Stability during movement. The support plate 3 will drive the inclined plate 4 and the filter screen 6 to slide during the sliding process, so that the screened objects on its surface enter the screening work, and the smaller screened objects will fall to the second screen. The screened objects move downward in sequence until the smallest screened objects enter the inside of the collection box 7, thereby completing the four-level classification of the screened objects. After the screening is completed, the inclined plate 4 and the filter screen 6 are removed by unscrewing the bolts 5, and the collection box 7 is taken out through the handle 8 to process the screened objects after the four-level classification again. After the processing is completed, the inclined plate 4 is fixedly connected to the support plate 3 again by the bolts 5;

[0024] S2. During the screening process, since the inclined plate 4 is designed to be inclined, the screened objects will first be concentrated at the center during the screening process, thereby making the screening work more convenient.
