[0002] Pumpkin seeds are the seeds found in pumpkin fruits. They are a common nut-like food with various characteristics and uses. During harvesting and initial processing, pumpkin seeds may be mixed with impurities such as stones, soil, insects, pumpkin pulp, and pumpkin shells. Sorting can remove these foreign objects and ensure the purity of pumpkin seeds.

[0003] The existing patent (publication number: CN108114902A) discloses that "the present invention relates to the field of seed sorting and discloses a pumpkin seed sorting machine, comprising a machine body, a sealing cover, and a sealing plate.

The aperture of the first screen is larger, which is used to remove larger impurities. The larger impurities are discharged through the first outlet. The aperture of the second screen is smaller, which is used to remove smaller impurities. The smaller impurities fall into the draw box at the bottom of the screening box for centralized recycling and processing. In the process of falling, the pumpkin seeds will pass through two shelling rollers to shell the pumpkin seeds. After preliminary screening and shelling, the pumpkin seeds enter the subsequent air separation link through the second outlet. After entering the protective mechanism, the pumpkin seeds will pass through the transmission equipment and enter between the ventilation mechanism and the wind screening mechanism. A plurality of second windows are provided on the second side panel of the wind screening mechanism, and a fan is installed inside. After the fan is started, wind is generated, and combined with the heating pipe, the light impurities in the pumpkin seeds are blown to one side of the transmission equipment to achieve air separation and dry the pumpkin seeds. Multiple first windows are provided on the first side panel, and a filter is clamped inside to ensure air flow while preventing dust from overflowing. During operation, the driving motor in the dust removal mechanism drives the fan blades to rotate, generating airflow, and the dust generated during the screening process is collected by the dust collecting bag to prevent dust from overflowing, keeping the interior and surrounding environment of the device clean. The side baffles and the feed port are used to connect the protective mechanism with the vibration screening mechanism to ensure that the pumpkin seeds enter the air separation link smoothly. The telescopic plate can be opened when necessary to facilitate inspection and maintenance inside the device. The pumpkin seeds and impurities after air separation are respectively transmitted to the recycling mechanism for recycling through the transmission equipment. A supporting cross bar is provided on the upper surface of the recycling box, a first handle is fixed in the middle position, and a second handle is fixed at both ends, so that the user can pick up multiple recycling mechanisms individually or simultaneously, which is convenient for operation.
