[0024] The structure of a seed screening device for rice biological breeding provided by the present invention is as Figure 1 and Figure 2As shown in the figure, it includes a frame 1. A collecting hopper 101 is fixed between the frames 1. A control row key 102 is installed on the surface of the frame 1, and the model of which can be selected from the LA series. A slide plate 103 is arranged on the surface of the frame 1. A sieve frame 104 is placed at the bottom of the collecting hopper 101, and the sieve frame 104 is located above the collecting hopper 101. A primary screening mechanism 2 is arranged on the surface of the frame 1. The primary screening mechanism 2 is composed of a primary sieve box 201 and a primary screening component 202. The primary sieve box 201 is fixed above the frame 1 through a support frame. A primary screening component 202 is arranged inside the primary sieve box 201. A second sieve mesh 2021, a second collecting seat 2022, a first sieve mesh 2023, a first collecting seat 2024 and a discharge pipe fitting 2025 are arranged inside the primary screening component 202. The first collecting seat 2024 is fixed at the bottom inside the primary sieve box 201. The first sieve mesh 2023 is fixed on the surface of the first collecting seat 2024. One end of the first sieve mesh 2023 is fixedly connected to the inner wall of the primary sieve box 201. The structure of the first sieve mesh 2023 is an inclined structure. A second collecting seat 2022 is fixed on one side inside the primary sieve box 201. The second collecting seat 2022 is located on one side of the first collecting seat 2024. The second sieve mesh 2021 is embedded on the surface of the second collecting seat 2022. One end of the second sieve mesh 2021 is fixedly connected to the inner wall of the primary sieve box 201. The second sieve mesh 2021 is located below the first sieve mesh 2023. Discharge pipe fittings 2025 are fixed on both sides of the primary sieve box 201. One ends of the discharge pipe fittings 2025 respectively extend to the surfaces of the second collecting seat 2022 and the first collecting seat 2024. Valves are installed on the surfaces of the discharge pipe fittings 2025.

[0025] During use, pour the rice seeds to be screened into the inside of the primary sieve box 201. At this time, the rice seeds are initially screened under the action of the first sieve mesh 2023, so that the dust impurities and shriveled seeds in the rice seeds pass through the first sieve mesh 2023 and fall into the first collecting seat 2024, and can be discharged along the first collecting seat 2024 to one side of the discharge pipe fitting 2025. The valve on the surface of the discharge pipe fitting 2025 can be opened to discharge the dust impurities and shriveled seeds. At the same time, the screened rice seeds slide along the first sieve mesh 2023 under the action of gravity, and then the rice seeds fall onto the surface of the second sieve mesh 2021. Similarly, the rice seeds are initially screened under the action of the second sieve mesh 2021 to realize the primary screening function of the seed screening device for rice seeds.

[0026] Further, as Figure 4As shown, the skateboard 103 and the sieve frame 104 are detachably connected by a picking and placing mechanism 3. The inside of the picking and placing mechanism 3 includes a slide bar 301 and a picking and placing component 302. Slide bars 301 are fixed at both ends of the sieve frame 104. The skateboard 103 and the sieve frame 104 are detachably connected by the picking and placing component 302. A fastening bolt 3021 and a chute 3022 are arranged inside the picking and placing component 302. Chutes 3022 are provided on both sides of the bottom of the skateboard 103. The chutes 3022 and the slide bars 301 are slidably matched with each other. Fastening bolts 3021 are threadedly connected to the surfaces of the skateboard 103. One end of each fastening bolt 3021 penetrates through the skateboard 103 and is threadedly fastened to the surface of the slide bar 301.

[0027] During use, after screening is completed, the fastening bolts 3021 can be loosened to move the fastening bolts 3021 away from the slide bars 301. Then, the sieve frame 104 is pulled, so that the sieve frame 104 drives the slide bars 301 to be pulled out along the chutes 3022, thereby removing the sieve frame 104. Then, the seeds inside the sieve frame 104 can be poured into the corresponding collection place to realize the function that the seed screening device is convenient for taking out rice seeds.

[0028] Further, as Figure 2 and Figure 3 shown, a shaking mechanism 4 is arranged at the bottom of the frame 1. The shaking mechanism 4 is composed of a guide groove 401 and a shaking component 402. A guide groove 401 is formed on the surface of the frame 1. The guide groove 401 and the skateboard 103 are slidably matched with each other. A shaking component 402 is arranged inside the guide groove 401. The inside of the shaking component 402 includes a stretching spring 4021, a driving motor 4022 and a cam 4023. A stretching spring 4021 is fixed at one end inside the guide groove 401. One end of the stretching spring 4021 is fixedly connected to one end of the skateboard 103. A driving motor 4022 is installed at the bottom of the frame 1. The model of the driving motor 4022 can be selected from the JO series. The input end of the driving motor 4022 is electrically connected to the output end of the control key array 102. The output end of the driving motor 4022 is fixed with a rotating shaft through a coupling. One end of the rotating shaft penetrates through the frame 1 and is fixed with a cam 4023. The cam 4023 is located on one side of the skateboard 103.

[0029] During use, the pre-screened rice seeds fall into the interior of the sieve frame 104. At this time, the control row key 102 can be operated to control the driving motor 4022 to work. Under the action of the driving motor 4022, the cam 4023 is driven to rotate, so that the cam 4023 presses the slide plate 103, causing the slide plate 103 to slide to the right along the guide groove 401, driving the sieve frame 104 to move synchronously. According to the characteristics of the cam 4023, when the end of the cam 4023 close to the rotating shaft approaches the slide plate 103, the slide plate 103 loses the thrust of the cam 4023. At this time, the slide plate 103 is reset under the action of the extension spring 4021, causing the sieve frame 104 to move to the left. Therefore, under the action of the shaking mechanism 4, the sieve frame 104 can be shaken left and right, accelerating the screening time of the rice seeds inside the sieve frame 104, so as to realize the shaking screening function of the seed screening device for the sieve frame 104.

[0030] Working principle: During use, first pour the rice seeds to be screened into the interior of the primary sieve box 201. At this time, the rice seeds are preliminarily screened under the action of the first sieve mesh 2023, so that the dust impurities and shriveled seeds in the rice seeds pass through the first sieve mesh 2023 and fall into the first collection seat 2024, and can be discharged along the first collection seat 2024 to one side of the discharge pipe fitting 2025. The valve on the surface of the discharge pipe fitting 2025 can be opened to discharge the dust impurities and shriveled seeds. At the same time, the screened rice seeds slide along the first sieve mesh 2023 under the action of gravity, and then the rice seeds fall onto the surface of the second sieve mesh 2021. Similarly, the rice seeds are preliminarily screened under the action of the second sieve mesh 2021, so as to realize the primary screening function of the seed screening device for the rice seeds, screening the dust impurities and shriveled seeds in the rice seeds, thereby improving the screening effect when the seed screening device is used.

[0031] The pre-screened rice seeds fall into the interior of the sieve frame 104. At this time, the control row key 102 can be operated to control the driving motor 4022 to work. Under the action of the driving motor 4022, the cam 4023 is driven to rotate, so that the cam 4023 presses the slide plate 103, causing the slide plate 103 to slide to the right along the guide groove 401, driving the sieve frame 104 to move synchronously. According to the characteristics of the cam 4023, when the end of the cam 4023 close to the rotating shaft approaches the slide plate 103, the slide plate 103 loses the thrust of the cam 4023. At this time, the slide plate 103 is reset under the action of the extension spring 4021, causing the sieve frame 104 to move to the left. Therefore, under the action of the shaking mechanism 4, the sieve frame 104 can be shaken left and right, accelerating the screening time of the rice seeds inside the sieve frame 104, so as to realize the shaking screening function of the seed screening device for the sieve frame 104, thereby improving the working efficiency when the seed screening device is used.

[0032] After the screening is completed, the fastening bolt 3021 can be loosened to move the fastening bolt 3021 away from the slide bar 301. Subsequently, the sieve frame 104 is pulled, so that the sieve frame 104 drives the slide bar 301 to be withdrawn along the chute 3022, thereby removing the sieve frame 104. Then, the seeds inside the sieve frame 104 can be poured into the corresponding collection place to realize the function that the seed screening device is convenient for taking out rice seeds, thereby improving the convenience of the seed screening device when taking out rice seeds, and finally completing the use of the seed screening device.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
