[0008] The screening assembly includes a housing component that slides within the support assembly and a screening component that slides within the housing component.
[0009] The support assembly includes a rectangular box, inside which are fixed two symmetrical concave plates. Guide columns are slidably fitted through both concave plates. A base plate is fixed to the bottom of each guide column below the concave plate. The tops of both guide columns are dome-shaped. Two symmetrical rotating shafts are fixed to the inside of the rectangular box below the concave plates. Two symmetrical support plates are fixed to the inside of the rectangular box below the rotating shafts. An elastic spring, sleeved on the periphery of the guide column, is fixed between the base plate and the concave plate. A rotating cylinder is rotatably fitted to the periphery of each of the two rotating shafts. An inclined plate is fixed to the outer periphery of the rotating cylinder. A pressure plate, in contact with the inclined plate, is fixed to the bottom of the base plate. Several arc-shaped springs are fixed between the inclined plate and the support plate. Several extension rods are fixed to the outer periphery of the rotating cylinder, and striking balls are fixed to the ends of the extension rods.
[0010] The screening component slides in conjunction with the two concave plates.
[0011] The present invention is further configured such that: the box body includes a screening box that is slidably fitted inside a rectangular box, and the bottom of the screening box is provided with two symmetrical rotating grooves, and the inner walls of the two rotating grooves are rotatably fitted with a number of traveling wheels that are respectively rolled and fitted on two concave plates;

[0013] The present invention is further configured such that: a convex groove is provided through the side of the rectangular box, an inwardly extending guide groove is provided through the side of the rectangular box, and a U-shaped plate is fixed to the other outer side of the rectangular box.
[0014] The present invention is further configured such that: a drive motor is fixed to the inner wall of the U-shaped plate, a rotating plate is fixed to the output shaft of the drive motor, and a lever is fixed to the side of the rotating plate;
[0015] The outer side of the screening box is fixed with a slider that slides inside the guide groove. A vertical plate is fixed to the side of the slider, and a sliding groove that slides through the side of the vertical plate to engage with the lever.
[0016] The present invention is further configured such that: a plurality of upwardly extending guide holes are provided through the bottom of the rectangular frame;
[0017] The screening component includes several guide rods that are slidably fitted inside several guide holes.
[0018] The present invention is further configured such that: two symmetrical lifting plates are fixed at the bottom of the bottom of the several guide rods at the bottom of the rectangular frame, and the two lifting plates are in contact with the several extension rods;

[0036] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution:
[0037] Specifically, it refers to a multi-layer vibrating grading feed cleaning screen, including a support assembly 1, with a screening assembly 2 slidably fitted inside the support assembly 1; the screening assembly 2 includes a box body 3 slidably fitted inside the support assembly 1 and a screening component 4 slidably fitted inside the box body 3; the support assembly 1 includes a rectangular box 101, with two symmetrical concave plates 102 fixed inside the rectangular box 101, and guide columns 103 slidably fitted through both concave plates 102; a bottom plate 104 is fixed to the bottom of the guide columns 103 below the concave plates 102, and the tops of both guide columns 103 are dome-shaped; two symmetrical rotating shafts 105 are fixed inside the rectangular box 101 below the concave plates 102. Inside the rectangular box 101, two symmetrical support plates 106 are fixed below the rotating shaft 105. An elastic spring 107, which is sleeved and fitted on the periphery of the guide column 103, is fixed between the bottom plate 104 and the concave plate 102. A rotating cylinder 108 is rotatably fitted on the periphery of both rotating shafts 105. An inclined plate 110 is fixed on the outer periphery of the rotating cylinder 108. A lower pressure plate 111, which is in contact with the inclined plate 110, is fixed at the bottom of the bottom plate 104. Several arc-shaped springs 112 are fixed between the inclined plate 110 and the support plate 106. Several extension rods 113 are fixed on the outer periphery of the rotating cylinder 108. A striking ball 114 is fixed at the end of the extension rod 113. The screening component 2 is slidably fitted with the two concave plates 102.
[0038] Furthermore, the box body 3 includes a screening box 301 that is slidably fitted inside the rectangular box 101. The screening box 301 has two symmetrical rotating grooves 302 at its bottom. The inner walls of the two rotating grooves 302 are rotatably fitted with several traveling wheels 303 that are respectively rolled on the two concave plates 102. The bottom of the screening box 301 is connected to a rectangular frame 304, and a first screening screen 305 is provided at the bottom of the rectangular frame 304.
[0039] The specific application of this embodiment is as follows: When the entire device is screening feed raw materials to be screened, the rolling action of the traveling wheels 303 on the concave plates 102 enables the screening box 301 to slide back and forth on the two concave plates 102, thereby repeatedly rolling and squeezing the guide column 103 sliding on the concave plates 102. Combined with the elastic force of the elastic spring 107 fixed between the bottom plate 104 and the concave plates 102, the guide column 103 is driven to move back and forth up and down on the concave plates 102. When the guide column 103 moves back and forth up and down on the concave plates 102, the bottom plate 104 and the lower pressure plate 111 fixed to the bottom of the bottom plate 104 move synchronously. The top of the inclined plate 110 slides back and forth, thereby driving the rotating drum 108 to rotate back and forth on the circumferential side of the rotating shaft 105. This causes the several arc-shaped springs 112 fixed between the inclined plate 110 and the support plate 106 to be compressed back and forth synchronously. This causes the striking balls 114 fixed to the ends of the several extension rods 113 to move back and forth synchronously. This, in turn, causes the first screening screen 305 set at the bottom of the box body 3 to be struck back and forth, thereby cleaning the first screening screen 305 set on the box body 3. This prevents impurities from clogging the mesh of the first screening screen 305 during the final screening, thus preventing it from affecting the subsequent multi-stage screening process.
[0040] Example 2, please refer to Figure 1-7This second embodiment is an improvement on the first embodiment as follows: Specifically, a convex groove 115 is provided through the side of the rectangular box 101, and an inwardly extending guide groove 116 is provided through the side of the rectangular box 101. A U-shaped plate 117 is fixed to the other outer side of the rectangular box 101. A drive motor 118 is fixed to the inner wall of the U-shaped plate 117, and a rotating plate 119 is fixed to the output shaft of the drive motor 118. A lever 120 is fixed to the side of the rotating plate 119. A slider 306 is fixed to the outer side of the screening box 301 and slides inside the guide groove 116. A vertical plate 307 is fixed to the side of the slider 306, and a lever groove 308 that slides through the side of the vertical plate 307 and slides with the lever 120. A plurality of upwardly extending guide holes 309 are provided through the bottom of the rectangular frame 304. The screening component 4 includes a plurality of guide rods 401 that slide inside the plurality of guide holes 309 respectively. The bottom of the plurality of guide rods 401 is located at the bottom of the rectangular frame 304. Two symmetrical lifting plates 402 are fixed, and both lifting plates 402 are in contact with several extension rods 113; two symmetrical inclined plates 403 are fixed at the top of several guide round rods 401 inside the screening box 301; a second screening screen 404 is fixed between the two inclined plates 403 inside the screening box 301, and a third screening screen 405 is fixed between the two inclined plates 403 above the second screening screen 404; several return springs 406 are fixed at the top of the two lifting plates 402, which are respectively sleeved and fitted on the periphery of several guide round rods 401, and the top of several return springs 406 are fixedly connected to the bottom of the rectangular frame 304; support feet 109 are fixed on the two opposite outer sides of the rectangular box 101 below the U-shaped plate 117; a discharge port 122 is opened through the outer side of the rectangular box 101 below the two support plates 106; and a guide inclined plate 121 connected to the discharge port 122 is fixed inside the rectangular box 101 below the two support plates 106.
[0041] A specific application of this embodiment is as follows: In the process of screening feed, the feed raw material to be screened is first introduced from the top of the rectangular box 101 for preliminary primary and secondary screening. During the preliminary primary and secondary screening of the feed raw material, the drive motor 118 is started to drive the rotating plate 119 and the lever 120 fixed on the side of the rotating plate 119 to rotate circumferentially, so that the lever 120 slides back and forth in the sliding groove 308, thereby providing power for the sliding process of the slider 306 in the guide groove 116, so that the screening box 301 together with the screening component 4 slides back and forth horizontally in the rectangular box 101, thereby causing the feed to be screened inside the screening box 301 to be horizontally shaken back and forth, avoiding the accumulation of the feed to be screened inside the screening component 4 in a certain area, and improving the primary and secondary screening effect in the whole process.
[0042] When the feed after primary and secondary screening falls from the screening element 4 and enters the rectangular frame 304, the tertiary screening process is carried out simultaneously. This achieves a multi-stage screening process for the entire feed, effectively removing particulate impurities from the feed and preventing them from affecting its later use. As the screening box 301, along with the screening element 4, slides horizontally back and forth inside the rectangular box 101, its extension rods 113 simultaneously reciprocate upwards, providing a force for the upward movement of the two lifting plates 402. Several guide rods 401 fixed at the top move upward synchronously inside several guide holes 309. During the upward movement, they simultaneously compress several return springs 406 fixed between the lifting plate 402 and the rectangular frame 304. Combined with the elastic recovery force of the compressed return springs 406, the lifting plate 402 moves downward, causing the screening component 4 to reciprocate during the up-and-down process. This achieves horizontal and vertical vibration throughout the process, improving the screening effect and preventing the screening component 4 from clogging during screening.
