[0002] 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.

[0003] To ensure that the experimental results are not affected by seed quality, seeds are usually screened before planting to remove impurities and chaff, thus ensuring seed quality and improving germination rate.

[0004] 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.

Each seed outlet has a guide plate that slopes downwards near the air outlet. Both ends of the guide plate are equipped with baffle plates, and a seed collection box is placed under the baffle plates.

[0008] The air supply mechanism includes an air guide tube with several air guide plates inside. One end of the air guide tube is connected to the air inlet of the sorting box, and the other end is provided with a sleeve. The air outlet of the fan is fitted inside the sleeve, and a frequency converter is connected to the fan.

[0009] The adjustment bracket includes a set of fixed support rods and a set of adjustable support rods. The upper part of the adjustable support rods is movably fitted with a telescopic adjustment rod. The upper ends of the fixed support rods and the telescopic adjustment rods are respectively connected to the two sides of the sorting box by mounting pins.

[0010] Preferably, both the adjusting support rod and the telescopic adjusting rod are provided with adjusting holes, and adjusting pins are installed in the adjusting holes.

[0011] Preferably, a support plate is installed in the middle of the fixed support rod and the adjusting support rod, and the seed collection box is placed on the support plate.

[0024] Example 2:

[0025] like Figure 1 and 2 As shown, the small seed sorting device of this embodiment includes a sorting mechanism 1, an air supply mechanism 2, and an adjusting bracket 3, wherein:

[0026] The sorting mechanism 1 includes a sorting box 11, with an air inlet and an air outlet at both ends of the sorting box 11. A hopper 12 is provided at the top of the sorting box 11, and a baffle valve 13 is provided at the bottom of the hopper 12. At least one seed outlet 14 is provided at the bottom of the sorting box 11. A guide plate 15 is provided on the side of each seed outlet 14 that is close to the air outlet.

[0033] The working principle of this utility model is as follows: In use, seeds are added to the hopper 12, the blower 24 is started, and the slide valve 13 is pulled to open the bottom discharge port, allowing the seeds to fall into the sorting box 11. Higher-quality seeds, being heavier, fall through the seed outlet 14 into the seed collection box under the influence of the blower and gravity. Impurities and chaff, being lighter, flow out from the air outlet of the sorting box 11 under the blowing action of the blower 24. Furthermore, a waste collection mechanism 4 is provided. Air flows out from the filter screen 42 on the upper side of the waste discharge trough 41, while impurities and chaff fall into the waste collection box 43. The waste collection box 43 is connected to the lower end of the waste discharge trough 41 via lugs 44 and connecting pins 45, ensuring a seal between the two and facilitating the cleaning of impurities. Secondly, the seed discharge speed can be controlled by adjusting the opening and closing of the gate valve 13, and the speed of the fan 24 can be controlled by the frequency converter 25, thereby adjusting the wind speed to suit the screening of different types of seeds. That is, for heavier seeds, a higher wind speed can be controlled to prevent chaff from falling into the seed collection box 17, and for lighter seeds, a lower wind speed can be controlled to prevent high-quality seeds from flowing into the impurity collection box 43. In addition, an adjusting bracket 3 is provided to adjust the tilt of the sorting box 11, so that all high-quality seeds fall into the seed collection box 17.
