At the same time, through the provided drying device, the hot air blower blows hot air to dry the seeds. The structure of this device is simple, and it can simultaneously screen and dry the seeds for forestry planting. When the auger conveys the seeds, the seeds are constantly moving, improving the screening and drying efficiency of the seeds.
[0004] However, the screening structure of the above device is relatively fixed, and it can only screen seeds of a specific size, unable to meet the processing requirements of different types and particle sizes of seeds. Summary of the Utility Model
[0005] Aiming at the above technical deficiencies, the purpose of the utility model is to provide a seed screening device for forestry planting, which can adjust the sieve frame configuration according to actual needs, is applicable to the treatment of different types and particle sizes of seeds, and makes the device have a wide application prospect.
[0006] To solve the above technical problems, the utility model provides the following technical solutions:

Then, the cover plate 112 is opened, and the seeds to be screened and dried are evenly poured into the third sieve frame 111, and then the cover plate 112 is quickly covered to maintain the sealing inside the device. The heat dissipation holes on the top of the cover plate 112 help to discharge excess heat and moisture during the drying process, maintaining the suitability of the internal environment of the device. The internal wiring connections of the electric push rod 103 with the heater 107 and the fan 108 are all prior arts and will not be elaborated here.

Then, open the cover plate 112, evenly pour the seeds to be screened and dried into the third sieve frame 111, and then quickly cover the cover plate 112 to maintain the sealing of the interior of the device. The heat dissipation holes on the top of the cover plate 112 help to discharge excess heat and moisture during the drying process, maintaining the suitability of the internal environment of the device. Connect the power supply, start the heater 107 and the fan 108. According to the type and humidity of the seeds, the temperature of the heater 107 can be appropriately adjusted to achieve the best drying effect. Start the electric push rod 103, and the electric push rod 103 can adjust the position of the heating frame 106 as needed, thereby driving the sieve frames on the top of the heating frame 106 to move and screen the seeds in the sieve frames to ensure that the seeds are evenly heated during the screening and drying process. With the heat generated by the heater 107 and the blowing of the fan 108, hot air circulates in the heating frame 106 to dry the seeds. At the same time, due to the different diameters of the sieve holes at the bottom of the sieve frames, the seeds are gradually separated into different sieve frames under the action of vibration and air flow. Larger seeds will remain in the third sieve frame 111, medium-sized seeds will fall into the second sieve frame 110, and the smallest seeds will fall through the sieve holes of the second sieve frame 110 into the first sieve frame 109. This process is continuous until all the seeds are screened. When the drying and screening processes are completed, the third sieve frame 111, second sieve frame 110, and first sieve frame 109 can be removed in sequence to collect seeds of different sizes. When collecting, attention should be paid to avoiding mixing the seeds in different sieve frames.
