Technical Field

[0001] This utility model relates to the technical field of jujube screening devices, specifically a jujube screening device for preventing clogging. Background Technology

[0002] The processing of jujubes involves multiple steps, one of which is screening. Screening requires the use of screening devices, and there are many different types of jujube screening devices on the market to meet various needs.

[0003] However, the utility model patent with authorization announcement number CN215088630U discloses a jujube size sorting device; it can use a shaking method to sort jujubes, avoiding damage to fresh jujubes and ensuring jujube quality; it includes a workbench, a mounting rod, multiple sets of balls, multiple sets of sieve cylinders, a first connecting rod, a second connecting rod, a servo motor, a turntable, a gear plate, gears, and a reduction motor. The mounting rod is fixedly installed at the top center of the workbench. Multiple sets of balls are evenly distributed on the mounting rod. Multiple sets of sieve cylinders are rotatably connected to multiple sets of balls. Each set of sieve cylinders is provided with sieve holes. Each sieve cylinder is provided with a discharge hopper. The discharge hopper is provided with a pull-out baffle. Multiple sets of sieve cylinders are hinged to the first connecting rod. The gear plate is rotatably set on the workbench. The servo motor is fixedly installed on the gear plate. The turntable is rotatably set at the output end of the servo motor. One end of the second connecting rod is hinged to the bottom of the first connecting rod. The gear meshes with the turntable.

[0004] The existing technical solutions described above have the following drawbacks: jujubes are screened using components such as a turntable, toothed disc, and mounting rod, but the jujubes easily clog the mesh. Furthermore, when removing the screened jujubes, it is necessary to remove them separately from different screen cylinders, which is slow and reduces work efficiency. Additionally, directly pouring the jujubes into the screen makes screening difficult due to uncertain weight. Therefore, we propose an anti-clogging jujube screening device to solve the problems mentioned above. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a jujube screening device for preventing clogging, including a workbench 1, a first fixing plate 2, a storage frame 3, a first sieve cylinder 4, a second sieve cylinder 5, a first discharge port 6, a second discharge port 7, a third discharge port 8, a sealing plate 9, a threaded rod 10, a second fixing plate 11, a connecting rod 12, a first connecting shaft 13, a first motor 14, a stirring blade 15, a second connecting shaft 16, a second motor 17, and a storage cylinder 18.

[0033] Example 1: Existing methods involve directly pouring red dates into a sieve, but the uncertain quantity makes sieving difficult. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 and Figure 6 Since the quantitative structure includes a second connecting shaft 16, a second motor 17, and a storage cylinder 18, the inner end of the second connecting shaft 16 is fixedly connected to the center of the storage cylinder 18. The storage cylinder 18 is in a flipping structure on the upper side of the second sieve cylinder 5 through the second connecting shaft 16. Therefore, when the opening of the storage cylinder 18 is on the upper side, the red dates are poured into the inside of the storage cylinder 18 for quantitative measurement. After quantitative measurement, the second motor 17 is driven to rotate the second connecting shaft 16 on the first fixed plate 2 and the front second fixed plate 11. When the second connecting shaft 16 rotates, it drives the storage cylinder 18 to flip, so that the quantitative red dates are poured into the inside of the second sieve cylinder 5, thereby facilitating quantitative feeding.

[0034] Example 2: Existing methods for screening jujubes use components such as a turntable, toothed disc, and mounting rod. However, the jujubes easily clog the mesh. Therefore, this example uses the following technical solution: Figure 1 and Figure 2Since the first connecting shaft 13 is rotatably connected to the center of the storage frame 3, the first sieve cylinder 4 and the second sieve cylinder 5 respectively, and the stirring blades 15 are inlaid at equal angles on the outer surface of the first connecting shaft 13, the aperture of the porous structure of the first sieve cylinder 4 is smaller than the aperture of the porous structure of the second sieve cylinder 5, and the positions of the stirring blades 15 correspond one-to-one with the storage frame 3, the first sieve cylinder 4 and the second sieve cylinder 5. The stirring blades 15 are in a rotating structure on the upper side of the workbench 1 through the first connecting shaft 13. Therefore, when the first motor 14 works, it drives the first connecting shaft 13 to rotate inside the storage frame 3, the first sieve cylinder 4 and the second sieve cylinder 5, so that the first connecting shaft 13 drives the stirring blades 15 set at equal angles to rotate, so that the stirring blades 15 stir the red dates in the first sieve cylinder 4 and the second sieve cylinder 5 respectively, preventing the red dates from blocking the porous structure at the bottom of the first sieve cylinder 4 and the second sieve cylinder 5, thereby preventing the red dates from blocking the mesh.

[0035] Example 3: Existing methods for removing sifted dates require taking dates from different sieve cylinders separately, which is slow and inefficient. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 , Figure 4 and Figure 5 Since the feeding structure includes a sealing plate 9, a threaded rod 10, a second fixed plate 11, and a connecting rod 12, the sealing plate 9 is respectively engaged with the inside of the first discharge port 6, the second discharge port 7, and the third discharge port 8. The stirring blade 15 rotates on the upper side of the workbench 1 via the first connecting shaft 13, and the sealing plate 9 slides on the second fixed plate 11 via the threaded rod 10 and the connecting rod 12. Therefore, the storage box is placed at the lower end of the first discharge port 6, the second discharge port 7, and the third discharge port 8, respectively, and the threaded rod 10 is rotated to make it slide on the second fixed plate 11. The plate 11 rotates, and the connecting rod 12 drives the sealing plate 9 to move stably outward, so that the sealing plate 9 is separated from the inside of the first discharge port 6, the second discharge port 7 and the third discharge port 8 respectively. When the first connecting shaft 13 rotates, the stirring blade 15 stirs the red dates inside the collection frame 3, the first sieve cylinder 4 and the second sieve cylinder 5 respectively, so that the red dates inside the collection frame 3, the first sieve cylinder 4 and the second sieve cylinder 5 fall into the inside of the collection box for collection, thereby facilitating the rapid collection of sorted red dates. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
