Description

Technical Field

[0001] This utility model relates to the field of seed sorting technology, specifically to a vertical seed air sorting device for testing. Background Technology

[0002] Seeds are crucial to agricultural production, and their quality directly affects crop yield and quality. Seed screening and grading are essential for improving seed purity and germination rate.

[0003] Planting trials aim to improve agricultural production efficiency, ensure food safety, enhance the quality of agricultural products, and provide scientific basis and technical support for future agricultural development through scientific methods. The main objectives of planting trials include: increasing crop yield and quality; protecting crops from disasters; studying the impact of planting techniques on yield; assessing the biocompatibility of soil and fertilization; and determining optimal planting density.

[0004] To ensure that the experimental results are not affected by seed quality, seeds are usually screened before planting experiments to remove impurities and chaff, thereby ensuring seed quality and improving seed germination rate.

[0005] Most current seed sorting devices are designed for large-scale seed sorting in agricultural planting and are highly specialized. For small-scale seed sorting in agricultural planting experiments, manual sorting is usually used, which is not only inefficient but also inaccurate and makes it difficult to remove all chaff. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a vertical seed wind classifier for testing, which removes moldy, deteriorated or defective seeds, as well as chaff and impurities by screening, ensuring that the remaining seeds are of high quality, thereby improving the germination rate, avoiding additional harvesting or processing costs caused by seed quality problems, and reducing problems such as inaccurate test results caused by seed quality problems.

[0007] This utility model provides a vertical seed air-separation device for experimental use, comprising a seed selection mechanism, a material holding mechanism, and an air supply mechanism, wherein:

[0008] The seed selection mechanism includes a vertically arranged sorting tube with an air outlet at the top and an impurity outlet on the side wall of the sorting tube. An outlet pipe is connected to the impurity outlet, and an impurity collection cup is detachably mounted on the outlet pipe. A baffle plate is provided inside the sorting tube. The baffle plate is inclined and its lower end is located at the lower edge of the impurity outlet, while its higher end is provided with a ventilation opening.

[0009] The material holding mechanism includes a material cup, which has an opening at the top and is connected to the bottom of the sorting tube, and a filter screen base plate at the bottom.

[0010] The air supply mechanism includes a fan, the air outlet of which is connected to a corrugated pipe, and the corrugated pipe is connected to the lower end of the material cup.

[0011] Preferably, the air outlet is equipped with an impurity filter.

[0012] Preferably, the lower end of the sorting tube is connected to a telescopic sleeve.

[0013] Preferably, the upper edge of the material cup is provided with a collar, the outer diameter of which is smaller than the outer diameter of the material cup and the inner diameter of the telescopic sleeve, and the telescopic sleeve can be telescopically fitted onto the collar.

[0014] Preferably, it also includes a mounting bracket, which includes a base and a vertical plate. The vertical plate is provided with an upper support plate and a lower support plate. The upper support plate is provided with a sorting pipe mounting hole, and the lower support plate is provided with an air outlet. The corrugated pipe is connected to the air outlet.

[0015] Preferably, the outer wall of the sorting tube is provided with a flange, the sorting tube is sleeved in the sorting tube mounting hole and is limited and supported by the flange, and the lower end of the material cup is detachably fitted into the air outlet.

[0016] The beneficial effects of this invention are as follows: This small-scale seed sorting device utilizes the weight difference between chaff and high-quality seeds. By applying the difference between upward airflow and gravity, the chaff is swept upwards and separated from the high-quality seeds. Screening removes moldy, spoiled, or defective seeds, as well as chaff and impurities, ensuring that the remaining seeds are of high quality. This improves the germination rate, avoids additional harvesting or processing costs due to seed quality issues, and reduces inaccurate test results caused by seed quality problems. Furthermore, the device has a simple structure, is easy to use, suitable for sorting small quantities of seeds in agricultural planting experiments, and has wide applicability, adaptable to various seed sorting applications.

The outer diameter of the collar 23 is smaller than the outer diameter of the material cup 21 and the inner diameter of the telescopic sleeve 18.
