Description

Technical Field

[0001] The utility model relates to the technical field of seed sorting equipment, in particular to a mung bean seed sorter. Background Art

[0002] The sorting of mung bean seeds is an important part of the mung bean planting process. Its purpose is to ensure the quality and germination rate of the seeds, thereby improving the yield and quality of mung beans.

[0003] When sorting mung bean seeds, various types of sorting equipment are used, such as the Chinese utility model patent disclosed by publication number CN206009190U: dust removal seed sorting box. This application sets an inclined screen plate so that seeds containing impurities can be filtered by the screen plate after entering the box through the feed inlet, so that impurities such as fine sand, gravel, and soil fall directly onto the guide surface and are discharged from the second discharge port under the action of the guide surface. The seeds with full particles suitable for planting can be guided by the screen plate by the first discharge port. At the same time, by setting the dust removal port and the dust removal fan, the dust generated in the sorting process can be discharged into the dust removal device connected to the dust removal fan to avoid pollution to the environment. However, since the seeds are mixed with not only dust but also some impurities such as bean shells and straws, after screening out the fine sand, gravel, soil and other impurities in the mung beans, this application cannot effectively remove the light impurities such as bean shells and straws, and they will eventually enter the collection container together with the mung beans, resulting in low sorting quality.

With the arrangement of the fan 2, the fixed pipe 15 and the air nozzle 9, some light impurities mixed in the grains and impurities such as mung bean shells can be blown away when the feed hopper 8 is fed;

[0022] like Figure 2-Figure 3As shown, three support beams 16 are fixedly installed at the lower end of the guide plate 13, and one end of the three support beams 16 is respectively fixedly installed on one side of the separation box 10, and the installation angle of the guide plate 13 is consistent with the installation angle of the screening cylinder 7. With the arrangement of the guide plate 13, part of the impurities when the feed hopper 8 is fed can be guided to the waste hopper 12 for collection through the guide plate 13. A plurality of anti-reverse plates 17 are fixedly installed on the inner side of the waste hopper 12, and two anti-reverse plates 17 form a group, and the two anti-reverse plates 17 are in an inverted eight-shaped structure. Two fixed blocks 18 are also fixedly installed at the lower end of the waste hopper 12, and a waste box 19 is movably installed at the lower end of the waste hopper 12 through the fixed block 18.
