[0002] Feed is a general term for food for animals raised by all people. Feed is usually made from more than ten varieties of raw materials including soybeans, soybean meal, corn, fish meal, etc., which can meet the energy and trace elements required for animal growth. In the production process of feed, various raw materials need to be processed first. In this process, it is usually necessary to use a vibrating grading screen to refine and screen the raw materials, so as to make the raw materials finer, so as to facilitate the subsequent pre-mixing and further processing of various raw materials.

[0003] It is common that after a period of use, some hard-to-fall raw materials are easily stuck in the sieve holes of the vibrating grading screen. Usually, the screen is fixed on the vibrating grading screen. Due to the obstruction and the cumbersome removal process, it is cumbersome and time-consuming to clear the screen, which is not convenient enough.

[0004] Therefore, it is necessary to provide a new vibration grading screen to solve the above-mentioned technical problems. Utility Model Content

A hinge rod 10 is rotatably installed on the transfer block 9, and the other end of the hinge rod 10 is rotatably connected to the hinge block 4. The same frame block 11 is longitudinally slidably installed on the three connecting plates 3, and a plurality of hooks 12 are fixedly installed on the inner wall of the frame block 11. The plurality of hooks 12 are divided into three groups, and each group of hooks 12 is distributed in a rectangular array. Three mounting plates 13 are slidably installed on the plurality of hooks 12, and the three mounting plates 13 are all slidably installed in the frame block 11. Filters 14 are fixedly installed on the three mounting plates 13, and a discharge port 15 is opened on the left side of the box body 1.

[0023] A side plate 16 is fixedly installed on one side of the box body 1, a U-shaped rod 17 is fixedly installed on one side of the side plate 16, a rectangular block 18 is slidably installed on the U-shaped rod 17, a hopper 19 is fixedly installed on one side of the rectangular block 18, and the bottom of the hopper 19 is directly opposite to the center of the filter screen 14.

[0024] In order to lift the box 1 off the ground and provide sliding space for the three horizontal plates 2, a base is fixedly installed at the bottom of the box 1, and movable holes are opened on both sides of the box 1. Rolling balls are inlaid on the top and bottom inner walls of the two movable holes, and the four rolling balls are respectively in contact with two corresponding horizontal plates 2.

[0025] In order to prevent the adapter block 9 and the hinge rod 10 from separating and increase the stability of the connection between the two, a circular block is fixedly installed on the end of the adapter block 9 away from the cam 8, and a second rolling ball is embedded on one side of the circular block, and the second rolling ball is in contact with one side of the cam 8.

[0026] In order to determine the position of the frame block 11 on the three transverse plates 2 , limit blocks are fixedly installed on both sides of the frame block 11 , and the bottoms of the two limit blocks are in contact with the tops of the corresponding transverse plates 2 .

[0027] In order to prevent the feed from splashing around during screening, a guard plate is fixedly installed on the top of the three mounting plates 13. The three mounting plates 13 are provided with mounting holes. The widths and lengths of the three mounting holes are different. The inner walls of the three mounting holes are fixedly connected to the three filter screens 14 respectively. The filter hole diameters on the three filter screens 14 are different. The filter hole diameters on the three filter screens 14 are reduced layer by layer to facilitate screening of feed of different sizes from top to bottom.

[0028] The working principle of the vibrating grading screen provided by the utility model is as follows:

[0029] In this method, in the initial state, the hopper 19 is located directly above the three filter screens 14. When the raw materials need to be screened, the motor 7 is started, and the output shaft of the motor 7 will drive the rotating rod 6 fixedly connected thereto to rotate. The rotating rod 6 drives the cam 8 during the rotation process. The front end of the cam 8 will gradually approach the direction of the box body 1 during the rotation process. While the cam 8 is rotating, the adapter block 9 will generate a driving force on the hinge block 4 through the hinge rod 10, thereby pushing the connecting plate 3 on the right side through the hinge block 4, and the three transverse plates 2 are pushed by the connecting plate 3 to slide to the left on the box body 1 at the same time. After the front end of the cam 8 rotates to a certain position, it will gradually turn away from the box body 1. At this time, the three transverse plates 2 slide to the right on the box body 1 driven by external force. Under the continuous action of the cam 8, the three transverse plates 2 will slide back and forth left and right on the box body 1, and the three mounting plates 13 are synchronously driven by the three transverse plates 2 through the frame block 11.

[0030] After that, the raw materials to be screened are slowly poured into the hopper 19, and the raw materials in the hopper 19 will slowly fall into the mounting plate 13 at the top through the discharge port 15 at the bottom. The raw materials fall down by themselves, and the raw materials pass through three filter screens 14 that vibrate left and right. Impurities of three different sizes are intercepted in sequence from large to small on three filter screens 14 with different filter hole diameters, thereby completing the screening of the raw materials. After three screenings, the finest raw materials will fall into the bottom of the box body 1, follow the curvature of the bottom of the box body 1, and slide out of the box body 1 through the discharge port 15 to complete the screening. Subsequently, the larger raw materials filtered out on the three filter screens 14 can be taken out through the material taking port.

[0031] Compared with the related art, the vibrating grading screen provided by the utility model has the following beneficial effects:

[0032] In the utility model, the three horizontal plates 2 are driven by the motor 7 to slide back and forth on the box body 1, and the raw materials dropped from the hopper 19 gradually pass through the three filter screens 14. The raw materials are screened three times by the three filter screens 14, so that the filter screens 14 can separate raw materials of different sizes, which is convenient for taking raw materials of appropriate sizes, so as to obtain more refined raw materials for subsequent use. The frame block 11 is slidably installed on the three horizontal plates 2, which is convenient for taking the entire frame block 11 out of the box body 1. The three filter screens 14 are installed on the frame block 11 in a sliding form, which can not only ensure the stability of the connection between the two, but also facilitate the three filter screens 14 to be removed from the frame block 11 one by one for dredging and cleaning, thereby improving the convenience of operation and saving time.
