[0021] An embodiment of the present utility model provides a seed screening device for crop planting, as Figures 1-4 shown. The seed screening device for crop planting includes: a base plate 1, a screening box 2 is provided on the top of the base plate 1 for storing water to screen seeds for crop planting; a placement plate 3, the placement plate 3 is provided in the screening box 2, and a liftable screening barrel 4 is provided on the placement plate 3 for holding seeds to be screened; an aeration pipe 5, the aeration pipe 5 is fixedly installed in the screening box 2 for aerating the water in the screening box 2, and the aeration pipe 5 is located below the placement plate 3; an aeration fan 6, the aeration fan 6 is fixedly installed on the base plate 1, and the air outlet end of the aeration fan 6 is fixedly communicated with the aeration pipe 5 through an air supply pipe 7 for supplying air to the aeration pipe 5; an overflow pipe 8, the overflow pipe 8 is fixedly communicated with the screening box 2 for discharging shriveled seeds and impurities floating on the water surface; a filtering mechanism, the filtering mechanism is provided on the base plate 1 for pre-filtering the air entering the aeration fan 6.
[0022] In this embodiment, the base plate 1 serves as the support foundation of the entire screening device, stably bearing various components above to ensure the stability of the screening process; the screening box 2 is a key component designed for storing and screening crop seeds. By screening in a water environment and utilizing the differences in physical properties such as seed density and buoyancy, preliminary grading of seeds is achieved. This method is gentler than mechanical vibration or strong sieving, helping to protect the epidermis and germ of seeds from damage; the placement plate 3 is arranged inside the screening box 2 and is used to support the sieve barrel 4. This design enables the sieve barrel 4 to be conveniently lifted out of the screening box 2, facilitating the addition and removal of seeds, and at the same time provides a stable screening platform for the seeds inside the sieve barrel 4; the design of the sieve barrel 4 being liftable makes the handling of seeds before and after screening simple and fast; the sieve barrel 4 is used to hold the seeds to be screened. By immersing it in the water in the screening box 2 and utilizing the buoyancy of water, seeds of different masses are naturally stratified, facilitating subsequent separation; the aeration pipe 5 is fixedly installed inside the screening box 2, below the placement plate 3. The aeration pipe aerates the water to form fine bubbles, and these bubbles will drive the movement of seeds and impurities in the water during the rising process, promoting the separation of seeds and impurities; the aeration fan 6 is fixedly installed on the base plate 1 and is connected to the aeration pipe 5 through the air supply pipe 7 to provide a stable air source for the aeration pipe 5; the overflow pipe 8 is fixedly connected to the screening box 2 and is used to discharge shriveled seeds and impurities suspended on the water surface. These light seeds and impurities will naturally float to the water surface due to buoyancy, and can be conveniently discharged through the overflow pipe to achieve further purification of the seeds; the filtering mechanism is arranged on the base plate 1 and is used for pre-filtering the air entering the aeration fan 6. This design can effectively prevent dust, impurities, etc. in the air from entering the aeration system, ensure the cleanliness of the aeration process, and thus protect the purity of the seeds. Through innovative designs such as water environment screening, aeration-promoted separation, and air pre-filtering, the epidermis and germ of seeds are effectively protected from damage, solving the problem that the epidermis and germ are easily damaged during the current seed screening process.
[0023] In a further preferred embodiment of the present utility model, the filtering mechanism includes: a filtering box 9 fixed on the base plate 1, and a plurality of filter plates 10 for pre-filtering air impurities are arranged inside the filtering box 9; a connecting pipe fixedly connected to the air outlet end of the filtering box 9, and the air outlet end of the connecting pipe is fixedly connected to the air inlet end of the aeration fan 6; a cover plate 11 arranged on the filtering box 9 and detachable; an air inlet pipe 12 fixedly connected to the filtering box 9.
[0024] In this embodiment, the filter box 9 is fixed on the base plate 1 and serves as the main component for air pre-filtration. The internal space of the filter box 9 provides a place for air pretreatment. Through the built-in filter plates 10, dust, particulate matter and other impurities in the air can be effectively removed, ensuring that the air entering the aeration blower 6 is clean and pollution-free. A plurality of filter plates 10 are arranged in the filter box 9 for pre-filtering air impurities. These filter plates 10 are usually made of fine mesh materials or porous media, which can effectively intercept and capture tiny particles in the air, ensuring the air quality after passing through the filter plates 10. The number of filter plates 10 can be adjusted according to actual needs to achieve the best filtering effect. The connecting pipe is fixedly connected to the air outlet end of the filter box 9, and its air outlet end is fixedly connected to the air inlet end of the aeration blower 6. The connecting pipe serves as a bridge between the filter box 9 and the aeration blower 6, ensuring that the pre-filtered clean air can smoothly enter the aeration blower for the next step of processing. A detachable cover plate 11 is arranged on the filter box 9. When the filter plates 10 are used for a long time, a certain amount of dust and impurities may accumulate, affecting the filtering effect. At this time, by removing the cover plate 11, the filter plates 10 can be conveniently taken out for cleaning or replacement. The air inlet pipe 12 is fixedly connected to the filter box 9 and serves as the inlet for external air to enter the filter box 9. The design of the air inlet pipe 12 should consider the air circulation and filtering effect to ensure that the external air can smoothly enter the filter box 9 and be effectively filtered by the filter plates. By adding components such as the filter box 9, a plurality of filter plates 10, the connecting pipe, the detachable cover plate 11 and the air inlet pipe 12, dust, particulate matter and other impurities in the air can be effectively removed, ensuring the cleanliness of the air entering the aeration blower 6 and preventing external impurities from entering the screening box 2 to cause further pollution to the water quality.

[0031] In a further preferred embodiment of the present utility model, a check valve is arranged on the air supply pipe 7, and a handle is fixedly installed on the top of the cover plate 11 and is used for grasping and lifting to open the cover.
[0032] In this embodiment, the check valve is arranged on the air supply pipe 7 to prevent gas backflow. During the aeration process, the check valve can ensure the unidirectional flow of gas and prevent problems such as pressure fluctuations or gas pollution caused by gas backflow; the handle is fixedly installed on the top of the cover plate 11 and is used for grasping and lifting to open the cover.

Compared with mechanical vibration or strong screening, it is gentler and effectively protects the seed epidermis and germ from damage; the combined use of the aeration pipe 5 and the aeration blower 6 forms fine bubbles by aerating the water, promoting the separation of seeds and impurities. At the same time, the design of the overflow pipe 8 automatically discharges light and shriveled seeds and impurities, further improving the purity of the seeds.
