Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seed impurity removal technology, and in particular relates to a seed impurity removal device. Background Technology
[0002] Seeds are reproductive organs produced during plant reproduction, comprising the plant's plumule, endosperm, and seed coat. They are the carriers of genetic material passed down through sexual reproduction and are typically formed by the union of pollen and ovules. To remove impurities from seeds and ensure their purity and quality, seed purification processes are performed using specialized equipment.
[0003] A patent application with publication number CN219581100U discloses a seed impurity removal device, including a main body with a discharge port at the upper end and a motor on the side of the discharge port. The device comprises movable parts, a movable groove, a movable pin, a connecting rod, a baffle, a discharge port, a diverter plate, a screen, a vibrator, protrusions, a dustproof net, and a fan. The motor drives the movable parts to rotate. Under the action of the movable groove and movable pin, the connecting rod moves the baffle back and forth, achieving intermittent seed discharge. The seeds falling into the screen are also evenly dispersed inside the device by the diverter plate, preventing seed accumulation during the impurity removal process and improving the device's impurity removal efficiency. Simultaneously, the protrusions cause the seeds to continuously tumble on the screen surface, ensuring even distribution and filtering of dust from inside the seeds, thus improving the device's environmental performance.
[0004] Although the above technical solution achieves the removal of impurities from seeds, there are still some problems in the process: when the screen screens the impurities in the seeds, the falling impurities will hit the fan blades at the bottom of the screen, which will generate a lot of noise and damage the blades. In addition, the dust generated during screening is blown away by the fan, and its flow direction is uncertain during the blowing process. Some of it will be discharged from the discharge port, which will affect the impurity removal environment. At the same time, the seeds also contain seed shell impurities, which cannot be effectively removed by the impurity removal process.
[0005] To address these issues, we provide a seed impurity removal device. Utility Model Content

[0032] Specifically: When seeds are fed through the feed pipe 9, the falling force of the seeds due to gravity is greater than that of the seed shell, so the seed shell separates from the seed. Furthermore, the negative pressure suction generated by the fan 4 is less than the force of the seeds falling due to gravity, ensuring that seeds are not sucked into the horizontal pipe 3. The dust inlet of the dust collection hood 11 is located inside the impurity removal box 2, and the dust collection hood 11 is fixedly connected to the impurity removal box 2.

[0033] The working principle of this utility model is as follows: the seeds that need to be cleaned are intermittently fed into the feed pipe 9, and the motor 12 drives the fan 4 to rotate through the rotating rod 13. When the seeds are fed in, they separate from the seed shell due to gravity. The negative pressure generated by the rotation of the fan 4 sucks the seed shell into the horizontal pipe 3. When the seeds fall to the top of the screen 5, they are separated from the dust. The negative pressure suction generated by the fan 4 guides them and sucks them all into the horizontal pipe 3. The rotating cleaning brush 14 sweeps them into the collection shell 7 for collection.
[0034] When the motor 12 rotates, it drives the movable rod 16 and the turntable 17 to rotate through the drive wheel and belt. Through the limit rod 18 and the limit plate 19, it drives the connecting rod 6 and the screen 5 to swing up and down, screening the stones and gravel in the seeds. The screened stones and gravel fall into the collection box 24, thus achieving the purpose of good impurity removal, protecting the impurity removal environment, and facilitating people's use.
