[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a seed selection and screening device, which is equipped with a motor 6 and a filter cylinder 7 to reduce clogging during use;

[0033] A motor 6 for power supply is snapped onto one side of the feed inlet 5. A filter cartridge 7 for screening is fixedly installed on one side of the motor 6. A spiral blade 18 for feeding seeds is snapped onto one side of the motor 6. A knob 19 for fastening is fixedly installed on one side of the spiral blade 18. A connecting rod 20 for assembly is fixedly connected to one side of the filter cartridge 7. A reinforcing rod 21 for stability is fixedly connected to one side of the filter cartridge 7. Therefore, the spiral blade 18 allows the injected seeds to flow into the device. The knob 19 makes the device connection more stable. The connecting rod 20 makes the filter cartridge 7 easier to assemble. The reinforcing rod 21 enhances the service life of the filter cartridge 7 and increases the practicality of the device.

[0034] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In order to allow the device to store unwanted impurities after screening during use, a support 1 and a storage box 2 are provided.

[0035] The device includes a storage box 2 with a support bracket 1 fixedly installed inside. A load-bearing rod 8 is fixedly connected to the top of the support bracket 1 for support, and a support structure 9 is fixedly installed to the bottom of the support bracket 1 for support. A discharge bucket 10 for the discharge of impurities is fixedly connected to the bottom of the storage box 2, and a bucket lid 11 for blocking the discharge bucket 10 is fixedly installed to the bottom of the discharge bucket 10. Therefore, the load-bearing rod 8 can support the parts of the device, making the device more stable. The support structure 9 can support the entire device and prevent the device from tipping over. The discharge bucket 10 can allow impurities to accumulate. The bucket lid 11 can block the discharge of impurities when needed, increasing the convenience of the device.

[0036] Please see Figure 1 and Figure 3 In order to make it easier to inject and discharge seeds during use, the device is provided with a discharge port 4 and a feed port 5;

[0037] A discharge port 4 for discharging seeds is fixedly installed on one side of the outer casing 3, and an inlet port 5 for pouring seeds is fixedly installed on the other side of the outer casing 3. A threaded hole 14 for assembly is provided on one side of the discharge port 4. A sliding plate 15 for reducing resistance is fixedly connected to the bottom of the discharge port 4. A square cover 16 for blocking is snapped onto the top of the inlet port 5. A handle 17 for gripping is fixedly connected to the top of the inlet port 5. Therefore, the threaded hole 14 makes the connection between the discharge port 4 and the device more secure. The sliding plate 15 reduces the friction of the falling seeds. The square cover 16 prevents dust from accumulating inside the device when it is not in use. The handle 17 makes it easier to remove the square cover 16 from the inlet port 5, increasing the service life of the device.

[0038] Example 1: The support structure 9 includes a directional wheel 901, which is fixedly installed at the bottom of the support structure 9. The directional wheel 901 makes the device easier to move, reduces the resistance to movement, avoids bumps and knocks during handling, and increases the service life of the device.

[0039] Example 2: The support structure 9 includes an inflatable wheel 902, which is fixedly installed at the bottom of the support structure 9. The inflatable wheel 902 makes the device more stable when moving, prevents the device from shaking when moving, reduces the possibility of parts becoming loose after the device moves, and increases the practicality of the device.

[0040] Example 3: The support structure 9 includes a support leg 903, which is fixedly installed at the bottom of the support structure 9. The support leg 903 makes the device more stable during operation, increases the friction between the device and the ground, makes the device less prone to slipping, and increases the stability of the device.

[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0042] In this invention, the working steps of the device are as follows:

[0043] First, turn on the motor 6, which drives the spiral blade 18 to rotate. The spiral blade 18 then drives the filter cylinder 7 inside the device to rotate. Next, open the square cover 16 and inject the seeds to be screened. After the seeds are screened by the spiral blade 18 and the filter cylinder 7, the desired seeds will flow out of the device through the discharge port 4, while impurities or unwanted seeds will fall directly into the storage box 2. Finally, open the lid 11 to clean the impurities from the storage box 2.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
