Description

Technical Field

[0001] This utility model belongs to the field of corn seed purity detection technology, and in particular relates to a portable corn seed purity detection device. Background Technology

[0002] The purity of corn seeds is a key indicator determining germination rate, crop yield, and quality. In agricultural production, purity testing needs to be conducted in multiple scenarios, including field harvesting and warehouse storage, to promptly screen qualified seeds and mitigate planting risks. However, existing corn seed purity testing devices generally suffer from a lack of portability and poor adaptability to various scenarios, severely hindering the implementation of testing in multiple settings.

[0003] Traditional testing devices are mostly one-piece, fixed structures, which are bulky and heavy, making them unsuitable for field transportation. Fields are often on unpaved dirt roads, and some plots even lack transportation channels. Traditional one-piece devices require multiple people to lift them or rely on small tricycles for transport, which is not only labor-intensive but also prone to tilting and damage to the outer shell due to bumpy roads. If testing is required across plots or regions, the device occupies a large amount of additional vehicle space, making it impossible for a single person to carry it. This greatly limits the need for on-the-spot testing and storage in the field, resulting in low testing efficiency.

[0004] To address these issues, we provide a portable corn seed purity testing device. Utility Model Content

[0005] The purpose of this invention is to provide a portable corn seed purity testing device. Through the function of the screening shell, the feeding shell, screening shell and base can be completely disassembled, breaking the fixed volume limitation of the overall assembly. That is, after disassembly, the feeding shell can be placed separately, and the screening shell and base can be stacked with the feeding shell. The device can be disassembled and can be compactly stored after disassembly, which is convenient for transportation to different testing scenarios such as fields and warehouses. It solves the problem that traditional integrated testing devices are large in size and difficult to transport, and solves the problem that existing traditional devices are mostly integrated fixed structures, which are bulky and heavy, making them difficult to adapt to field transportation scenarios.

Specific Implementation Example 1

[0044] Please see Figures 1-8 This utility model is a portable corn seed purity testing device, including a feeding shell 1 with a feeding channel 2 inside; a mounting frame 3 is fixed to one end of the feeding shell 1, and a positioning tube 4 is fixed to the side of the mounting frame 3 near the feeding shell 1; a screening shell 5 is movably connected to one side of the mounting frame 3, and a feeding groove 6 is opened on one side of the screening shell 5; a discharge groove 7 is opened on the side of the screening shell 5 away from the feeding groove 6, and a positioning shell 8 is fixed to the side of the screening shell 5 with the feeding groove 6; a first threaded tube 9 is fixed to the upper surface of the positioning shell 8, and a first threaded rod 10 is threadedly connected inside the first threaded tube 9; a positioning rod 11 is fixed to one end of the first threaded rod 10, and the positioning rod 11 is inserted into the positioning tube 4.

[0045] Specifically, a screening plate 12 is fixed on one side of the discharge chute 7, and a first partition plate 13 is fixed in the center of the screening plate 12; the screening plate 12 is located at the bottom of the feed chute 6 on one side as the normal corn kernel zone 14, and the screening plate 12 is located on the other side as the abnormal corn kernel zone 15.

[0046] Furthermore, a second partition 16 is fixed inside the abnormal corn kernel section 15, with the top of the second partition 16 inclined; the second partition 16 divides the abnormal corn kernel section 15 into a moldy corn kernel section 17 and an empty corn kernel section 18; an air-coupled ultrasonic detection probe 19 is fixed to one end of the inner wall of the screening shell 5, and a first blower 20 is fixed to the other end of the inner wall of the screening shell 5; a second blower 21 is fixed to one side of the abnormal corn kernel section 15; a reinforcing strip 22 is fixed to one side of the mounting frame 3, and a reinforcing groove 23 is opened on the outside of the feed chute 6; the reinforcing strip 22 matches the reinforcing groove 23.

[0047] The operation process of this embodiment is as follows: When using this device, if the flow rate during seed screening needs to be adjusted, the tilt angle of the feed shell 1 can be adjusted. That is, hold the second threaded rod 27 and rotate it. Since the second threaded rod 27 is threadedly engaged with the second threaded tube 26, and the limiting rod 31 restricts the rotation of the adjusting shell 25, the adjusting shell 25 will slide up and down along the limiting rod 31, thereby driving the feed shell 1 and the screening shell 5 to rotate around the fixed rod 24 to achieve tilt angle adjustment. After adjusting the angle, turn on the power switches of the first blower 20 and the second blower 21 and adjust them to a suitable wind speed; start the air coupling ultrasonic detection probe 19, hold the corn seed to be tested, and slowly pour it into the feed channel 2 of the feed shell 1 so that the seeds fall evenly. After the seeds fall into the screening shell 5 through the feed channel 2, the airflow blown by the first blower 20 performs the first screening of the seeds. That is, normal corn seeds are heavier and less affected by the airflow, and directly pass through the bottom of the discharge trough 7 and fall into the normal corn kernel section 14 on one side of the first partition 13 in the center of the sieve plate 12.

[0048] Moldy and empty corn kernels, being lighter, are blown by the airflow to the abnormal corn kernel section 15 on the other side of the sieving plate 12 and fall. At this time, the second blower 21 starts, performing a second screening of the abnormal seeds. Moldy corn kernels, being slightly heavier, are less affected by the airflow and fall directly into the moldy corn kernel section 17 on one side of the second partition 16 within the abnormal corn kernel section 15. Empty corn kernels, being the lightest, are blown by the airflow across the inclined second partition 16 and fall into the empty corn kernel section 18 on the other side. The feeding continues until all seeds are screened, and feedback from the air-coupled ultrasonic detection probe 19 assists in the screening process. This device helps determine seed purity and, combined with the zoning results, counts the number of normal, moldy, and empty-shelled seeds. In this device, the first partition 13 divides the sieve plate 12 into a normal corn kernel zone 14 and an abnormal corn kernel zone 15. Then, the second partition 16 further divides the abnormal zone into a moldy corn kernel zone 17 and an empty-shelled corn kernel zone 18, forming a multi-level classification structure. During screening, normal seeds, moldy seeds, and empty-shelled seeds can directly fall into their corresponding zones without the need for subsequent manual secondary sorting. This is especially suitable for rapid field testing scenarios, significantly saving sorting time, reducing labor costs, and avoiding classification confusion caused by mixed storage. Specific Implementation Example 2

[0050] Please see Figure 3 Based on the first specific embodiment, a fixing rod 24 is fixed on both sides of the feed shell 1, and an adjusting shell 25 is rotatably connected to the outside of the fixing rod 24; a second threaded tube 26 is fixed inside the adjusting shell 25, and a second threaded rod 27 is threadedly connected inside the second threaded tube 26.

[0051] Specifically, a transmission rod 28 is fixed to one end of the second threaded rod 27, and a bearing 29 is fixed to one end of the transmission rod 28; a base plate 30 is fixed to the outer ring of the bearing 29; a limit rod 31 is fixed to the upper surface of the base plate 30, and a limit hole 32 is opened on the surface of the adjusting shell 25; the limit rod 31 passes through the limit hole 32.

[0052] The operation process of this embodiment is as follows: When using this device, it needs to be assembled first. That is, take out the feeding shell 1 and the screening shell 5, align the mounting frame 3 on one side of the feeding shell 1 with the feeding groove 6 of the screening shell 5, and slowly fit them together to ensure that the contact surface between the mounting frame 3 and the screening shell 5 is flat. Push the feeding shell 1 so that the reinforcing strip 22 on the mounting frame 3 is accurately inserted into the reinforcing groove 23 on the outside of the feeding groove 6, initially fixing the positions of the two to prevent displacement during assembly. Rotate the first threaded rod 10 on the positioning shell 8 so that it is screwed down along the first threaded tube 9, driving the positioning rod 11 at the bottom to move down synchronously until the positioning rod 11 is completely inserted into the positioning tube 4 of the mounting frame 3. Tighten the first threaded rod 10 to complete the firm assembly of the feeding shell 1 and the screening shell 5. Take out the adjusting shell 25 and the bottom plate 30, and put the second threaded rod 2... 7. Align the second threaded tube 26 of the adjusting shell 25 and screw in the second threaded rod 27 to initially connect the adjusting shell 25 and the base plate 30. Align the limiting rod 31 on the upper surface of the base plate 30 with the limiting hole 32 on the surface of the adjusting shell 25. Slowly push the adjusting shell 25 so that the limiting rod 31 passes through the limiting hole 32 and extends out, ensuring that the adjusting shell 25 does not deviate when sliding along the limiting rod 31. In this device, the feeding shell 1, the screening shell 5 and the base 30 can be completely disassembled, breaking the fixed volume limitation after the overall assembly. That is, after disassembly, the feeding shell 1 can be placed alone, and the screening shell 5 and the base 30 can be stacked with the feeding shell 1. This device can be disassembled and can be compactly stored after disassembly, making it convenient to transport to different testing scenarios such as fields and warehouses, solving the problem of large size and difficult transportation of traditional integrated testing devices.
