Description

Technical Field

[0001] This utility model relates to the field of corn seed storage, and more specifically, to a corn selection and storage device. Background Technology

[0002] Corn seeds are reproductive organisms capable of growing into mature corn plants. They are formed from ovules through pollination and fertilization. As an important food crop and industrial raw material, the pre-treatment process before storage after harvesting corn plays a decisive role in ensuring storage safety, improving grain quality, and enhancing economic benefits.

[0003] Existing corn seed storage devices often encounter problems when storing corn seeds. After threshing, the corn is often mixed with light fibrous impurities such as corn silk, broken husks, and dust. Traditional processes rely on removing these impurities before storage. This separation process not only increases equipment investment, floor space, and energy consumption, but also, if the impurities are not treated in time, they will absorb moisture and cause localized mold growth, occupying effective storage space and increasing the cost and risk of subsequent processing. Furthermore, it is impossible to screen the seeds by size. Selecting large, plump seeds that meet the standards is one of the core objectives, while small, shriveled, and broken kernels are rejected as substandard or low-grade products. In view of this, we propose a corn selection and storage device to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6A corn selection and storage device includes a storage device body 1. A feed hopper 2, communicating with the interior, is fixedly connected to the upper surface of the storage device body 1. An air guide hood 3, also communicating with the interior, is embedded inside the feed hopper 2. The end of the air guide hood 3 is provided with a connecting flange, which connects to external impurity removal equipment. This allows the removal of light impurities such as corn silk, husk fragments, cob fragments, and husk fragments when the seeds fall due to gravity. Inside the storage device body 1, a sieve plate 4 is provided for selecting corn seeds. A guide hood 5, fixedly connected to the interior of the storage device body 1, is provided below the sieve plate 4. The guide hood 5 has a collection mechanism for collecting seeds that do not meet standards. The storage device 1 has a first collection box 6 for collecting corn seeds, and a second collection box 7 for collecting standard corn seeds is provided on the right side of the first collection box 6. A splash guard 8 for preventing corn seeds from splashing is fixedly connected to the top wall of the main body 1. A movable groove 9 is provided on the left side surface of the main body 1. A vibration mechanism is provided inside the movable groove 9. A leveling mechanism is provided inside both the first collection box 6 and the second collection box 7. Since the leveling mechanisms inside the first collection box 6 and the second collection box 7 are the same, the following description focuses on the leveling mechanism inside the second collection box 7. A cavity 10 is provided inside the bottom plate of the main body 1. A drive mechanism is provided inside the cavity 10.

[0031] In the above embodiment, the vertical distance between the splash guard 8 and the sieve plate 4 is set to 20-50 mm, which is slightly larger than the maximum particle size of the selected corn seeds (usually 10-15 mm) to ensure that the seeds pass through smoothly and avoid clogging.

[0032] Example 2

[0033] The corn selection and storage equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the vibration mechanism includes an extension plate 11, which is slidably connected to the inside of the movable groove 9 via a shaft. The right end face of the extension plate 11 is fixedly connected to the left side of the sieve plate 4 by bolts, so that the vibration of the vibration motor 12 is directly transmitted to the sieve plate 4 through the extension plate 11, driving the sieve plate 4 to vibrate. A baffle plate is provided on the side of the sieve plate 4 near the movable groove 9, thereby blocking the movable groove 9 and effectively preventing corn seeds from entering the movable groove 9. The lower surface of the extension plate 11 is fixedly connected to the vibration motor 12 for providing power. A first damping spring 13 is fixedly connected between the surface of the extension plate 11 and the inner wall of the movable groove 9, and the first damping spring 13 is movably sleeved on the outside of the shaft. The vibration motor 12 can be started by an external controller to drive the extension plate 11 and the sieve plate 4 to vibrate, thereby further improving the selection efficiency of the sieve plate 4 for corn seeds. The plump and standard corn seeds will fall into the inside of the second collection box 7 by the inclined surface of the sieve plate 4, while small-diameter, shriveled, and broken corn seeds will be collected through the first collection box 6.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a guide rod 24 is slidably sleeved on the right side of the sieve plate 4. The vertical rod 24 is fixedly connected to the top surface of the second collection box 7. The assembly method of the vertical rod 24 and the second collection box 7 can adopt existing mature technologies, such as bolts or snap-fit ​​assembly methods, as long as they can facilitate disassembly and assembly. It will not be elaborated in detail here. A second damping spring 15 is movably sleeved on the outside of the vertical rod 24. The upper end of the second damping spring 15 is fixedly connected to the sieve plate 4, and the lower end of the second damping spring 15 contacts the second collection box 7. Thus, when the sieve plate 4 vibrates, the first damping spring 13 and the second damping spring 15 cooperate to achieve buffering, ensuring the smoothness and uniformity of vibration.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a vertical plate 14 for shielding is fixedly connected to the right side of the sieve plate 4, and a vertical plate 14 is also fixedly connected to the upper surface of the second collection box 7. The two vertical plates 14 are in contact and slide against each other. By using the two vertical plates 14, the selected corn seeds can be shielded, thereby effectively preventing the selected corn seeds from falling between the second collection box 7 and the sieve plate 4.

[0036] It should be noted that, considering the service life of the vertical plate 14, the contact surfaces of the two vertical plates 14 can be made of a smooth material to reduce the friction between the vertical plates 14.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the leveling mechanism includes two actuating rods 16 for leveling corn seeds. The lower ends of the two actuating rods 16 are rotatably sleeved inside the bottom plates of the first collection box 6 and the second collection box 7, and the lower ends of the two actuating rods 16 are flush with the bottom surfaces of the first collection box 6 and the second collection box 7, respectively. The lower ends of the two actuating rods 16 are fixedly connected to rectangular blocks 17 for docking. By rotating the actuating rods 16, the corn seeds inside the collection box can be slowly stirred, thereby achieving the purpose of leveling the corn seeds during storage and avoiding excessive local accumulation.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the bottom plate of the storage equipment body 1 is fitted with two rotating platforms 18 for rotation. The center of the rotating platform 18 is provided with a through groove 19 extending out of the outer circumference. The through groove 19 is adapted to the rectangular block 17. When the rectangular block 17 is installed in the through groove 19 on the surface of the rotating platform 18, the actuating rod 16 will be coaxial with the rotating platform 18. Then, when the rotating platform 18 rotates, it can drive the actuating rod 16 to rotate.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the bottom wall of the storage device body 1 also has two through slots 19, and the two through slots 19 on the bottom wall of the storage device body 1 are connected to the through slots 19 on the surfaces of the two rotating tables 18 respectively. After the two through slots 19 are aligned, the collection box can be slid out from the inside of the storage device body 1.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the drive mechanism includes a rotating shaft 20 for rotation, which is rotatably connected inside the cavity 10. One end of the rotating shaft 20 rotatably penetrates into the interior of the storage device body 1. Two bevel gears 22 for transmission are fixedly sleeved on the outside of the rotating shaft 20. The lower surfaces of the two rotating platforms 18 are fixedly connected to a transmission shaft 21 for rotation. The lower ends of the two transmission shafts 21 rotatably penetrate into the interior of the cavity 10. The lower ends of the two transmission shafts 21 are also fixedly sleeved with bevel gears 22 for transmission. The two adjacent bevel gears 22 are meshed together. A drive motor 23 for providing power is fixedly connected to the outside of the storage device body 1. The output shaft of the drive motor 23 is fixedly connected to the rotating shaft 20 via a coupling. The drive motor 23 is started by an external controller. The rotation of the output shaft of the drive motor 23 drives the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 and the transmission interface of the bevel gears 22 drive the rotation of the two transmission shafts 21. The rotation of the transmission shafts 21 drives the rotation of the rotating platform 18.

[0041] In the above embodiments, as is well known to those skilled in the art, the working principles and wiring methods of the vibration motor 12 and the drive motor 23 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The corn selection and storage equipment provided by this utility model is used as follows:

[0043] First, the operator connects the air guide hood 3 to the external impurity removal equipment using the connecting flange. Then, when the seeds fall due to gravity, light impurities such as corn silk, husk fragments, cob fragments, and husk fragments can be removed.

[0044] Subsequently, the staff pours the corn seeds to be selected from the feed hopper 2 into the main body 1 of the storage equipment. At this time, the light impurities in the corn seeds will be separated and removed by the air guide 3. Then, the screen plate 4 is set to facilitate the separation of plump, large-diameter seeds from small-diameter, shriveled, and broken corn seeds. The plump, standard-compliant seeds will fall into the second collection box 7, while the non-standard corn seeds will fall into the first collection box 6. The splash plate 8 can block the splashed corn seeds when they fall.

[0045] Meanwhile, during the selection process, staff can start the vibration motor 12 through an external controller to drive the extension plate 11 and the sieve plate 4 to vibrate, thereby further improving the selection efficiency of corn seeds by the sieve plate 4.

[0046] In addition, staff can start the drive motor 23 through an external controller. The rotation of the output shaft of the drive motor 23 will drive the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 and the transmission interface of the bevel gear 22 will drive the rotation of the two transmission shafts 21. The rotation of the transmission shafts 21 will drive the rotation of the rotating table 18. When the rotating table 18 rotates, it will drive the toggle lever 16 to rotate. The rotation of the toggle lever 16 will slowly stir the corn seeds inside the collection box, thereby achieving the purpose of leveling the corn seeds during storage and avoiding excessive local accumulation.

[0047] Finally, when it is necessary to remove the selected corn seeds or remove corn seeds that do not meet the standards, since the drive motor 23 stops by controlling its stopping position through the controller, the through groove 19 opened on the surface of the rotating table 18 and the through groove 19 opened on the bottom wall of the storage equipment body 1 will be aligned and connected to each other. Then the staff can open the cabinet door of the storage equipment body 1 and separate the vertical rod 24 and the second collection box 7. At this time, the first collection box 6 and the second collection box 7 can be pulled out from the inside of the storage equipment body 1.
