Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, and more specifically, to a corn seed screening device for cultivation experiments. Background Technology
[0002] Before planting, corn seeds are usually screened using a screening device to improve the survival rate of the corn. This process distinguishes between inferior and superior seeds, selecting the plumpest kernels for seed cultivation, thereby increasing the survival rate and improving seedling quality.
[0003] Existing corn seed screening devices achieve grading and screening through multiple layers of sieve plates. However, corn seeds inevitably contain impurities such as corn ears and dust, which can affect the quality of the corn. Therefore, dust removal and impurity removal before sieving are essential.
[0004] A search revealed a corn seed screening device disclosed in Chinese Patent No. CN220635318U. This utility model uses a dust removal and impurity removal box, multiple shaking guide plates to slow down the falling speed of the seeds, and then a dust removal fan to extract the mixed dust and impurities, thereby achieving a certain cleaning effect and improving the quality of corn seeds.
[0005] However, in actual use, after screening the corn seeds, the seeds will gather together and be output. When the staff selects the corn seeds again, the seeds need to be spread out again, which affects the efficiency of subsequent corn seed selection. Utility Model Content

A fixing block 22 is fixedly connected to the output end of the electric push rod 17. Two guide plates 18 are fixedly connected to the inner side of the outer casing 1. A guide frame 19 is slidably connected to the top of the guide plate 18. The top of the guide frame 19 is snapped into place. There is a placement box 20, and the top of the placement box 20 has multiple slots 21. The bottom of the guide frame 19 is fixedly connected to the top of the fixing block 22. A dispersion mechanism is provided on the outside of the outer shell 1. The vibration motor 16 is used to vibrate the vibration plate 13, and multiple electric push rods 17 are used to assist the vibration of the vibration plate 13. At the same time, multiple baffles 15 are used to disperse and grade the corn seeds. Then, the guide frame 19 is used to drive the sliding of the placement box 20, so that the multiple slots 21 on the inside of the placement box 20 can collect and place the graded corn seeds.
[0025] Reference Figure 1 , Figure 3 and Figure 5As shown, the dispersion mechanism includes two air pumps 23. The bottom of the air pumps 23 is fixedly connected to the top of the outer shell 1. The output end of the air pumps 23 is fixedly connected to a pipe 24. One end of the pipe 24 is fixedly connected to an outer frame 25. Multiple dispersion plates 26 are fixedly connected to the inner side of the outer frame 25. The outer side of the outer frame 25 is fixedly connected to the inner side of the outer shell 1. An air outlet pipe 27 is fixedly connected to one side of the outer shell 1, and an air inlet pipe 29 is fixedly connected to the other side of the outer shell 1. Multiple fans 28 are fixedly connected to the bottom of the air outlet pipe 27. Air is input into the inner side of the outer frame 25 using the air pumps 23 and the pipe 24. The multiple inclined dispersion plates 26 are used to drop the corn seeds and blow away the impurities mixed between the corn seeds. The air outlet pipe 27, the fans 28 and the air inlet pipe 29 are used to ventilate the inside of the outer shell 1.
[0026] The working principle of this utility model is as follows: Before the corn seed cultivation experiment, the corn seeds are first put into the inside of the feeding hopper 3. The servo motor 4 is started to drive the distributing roller 5 to guide the corn seeds inside the feeding hopper 3, so that a part of the corn seeds fall through the feeding hopper 3 to the top of the dispersing plate 26. Then, air is input into the inside of the outer frame 25 through two air pumps 23 and pipes 24, and the air is dispersed by multiple dispersing plates 26. The corn seeds move to the next level dispersing plate 26 in sequence under the blowing of the wind on multiple inclined dispersing plates 26. At the same time, the wind blown out by the outer frame 25 and the dispersing plate 26 blows and separates the particulate impurities in the corn seeds. Then, multiple fans 28 are used to exhaust air into the inside of the outer shell 1 through the air outlet pipe 27 and the air enters into the inside of the outer shell 1 through the air inlet pipe 29, so that the air inside the outer shell 1 is completed. Then, the separated impurities gather on one side of the air outlet pipe 27 and fall to the bottom of the outer shell 1 through the baffle 6 and fall into the inside of the collection box 7 for collection.
[0027] After the corn seeds have been separated from impurities, they fall to the top of the sieve plate 10. With the vibration of the vibrating motor 12 and the assistance of multiple shock absorbers 11, the sieve plate 10 can filter out corn seeds that are not plump enough. Then, the sieved corn seeds fall to the top of the vibrating plate 13. After that, with the vibration of the vibrating motor 16 and the support of multiple shock absorbers 14, the vibrating plate 13 and multiple baffles 15 grade and convey the corn seeds. Then, the corn seeds fall sequentially to the top of the placement box 20 and the slot 21. At the same time, the electric push rod 17 drives the fixed block 22 and the guide frame 19 to slide on the top of the guide plate 18. The guide frame 19 drives the placement box 20 to arrange the falling corn seeds sequentially, so that multiple corn seeds are arranged sequentially inside the slot 21. Finally, the placement box 20 is removed from the inside of the guide frame 19 to complete the screening of the corn seeds.
