The terms "install", "connect", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] The present application is further described in detail below through drawings and examples.

[0034] Reference Figures 1 to 4 The embodiment of the present application provides a seed screening device for agricultural planting, including a shell 1 and a bottom plate 4. A screening component 2 is arranged inside the shell 1, and the shell 1 is fixedly mounted on the top of the bottom plate 4. A feeding component 3 is arranged on the top of the bottom plate 4. The screening component 2 includes a first screen 21, a second screen 22 and a bottom plate 23. The first screen 21, the second screen 22 and the bottom plate 23 are all fixedly mounted inside the shell 1 from top to bottom. A first discharge plate 24 is fixedly mounted on the front of the first screen 21, a second discharge plate 25 is fixedly mounted on the front of the second screen 22, and a third discharge plate 26 is fixedly mounted on the front of the bottom plate 23. The first screen 21, the second screen 22 and the bottom plate 23 are all inclined forward.

[0035] Side baffles 28 are fixedly mounted on the outer tops of the first screen 21 and the first discharge plate 24 , the second screen 22 and the second discharge plate 25 , and the bottom plate 23 and the third discharge plate 26 .

[0036] Three collecting barrels 27 are fixedly installed on the top of the bottom plate 4, and the collecting barrels 27 are respectively located below the first discharge plate 24, the second discharge plate 25 and the third discharge plate 26. The first discharge plate 24 is located on the left side inside the outer shell 1, the third discharge plate 26 is located on the right side inside the outer shell 1, and the second discharge plate 25 is located between the first discharge plate 24 and the third discharge plate 26.

[0037] In this embodiment, the aperture of the first sieve 21 is larger than the aperture of the second sieve 22. During screening, the seeds fall into the top of the first sieve 21 and roll on the first sieve 21. During rolling, the seeds with the aperture of the first sieve 21 larger than the aperture of the second sieve 22 will fall downward onto the second sieve 22. Similarly, the seeds with a size smaller than the aperture of the second sieve 22 will fall onto the bottom plate 23. The seeds remaining on the first sieve 21 are the largest in size, the seeds remaining on the second sieve 22 are the second largest in size, and the seeds on the bottom plate 23 are the smallest in size. The three seeds of different sizes enter the three different collection barrels 27 respectively through the first, second and third discharge plates, thereby realizing multi-stage screening of the seeds; and a new sieve with a suitable aperture size can be added between the two sieves to achieve more levels of screening effects.

[0038] Reference Figures 1 to 4 In one aspect of the present embodiment, the loading assembly 3 includes a bracket 32, which is fixedly mounted on the top of the housing 1. The bracket 32 ​​is rotatably connected to a screw rod 34 inside, a slider 33 is screwed to the outside of the screw rod 34, a discharge pipe 35 is fixedly mounted on the bottom of the slider 33, and the top of the slider 33 fits with the bottom of the bracket 32.

[0039] The discharge pipe 35 is located above the first screen 21 and at the highest point behind the first screen 21. A motor 36 is fixedly mounted on the side of the bracket 32, and the output shaft of the motor 36 passes through the side wall of the bracket 32 ​​and is fixedly connected to the screw 34.

[0040] The loading assembly 3 also includes a material box 31, a support leg 38 is fixedly installed at the bottom of the material box 31, and the support leg 38 is fixedly installed on the top of the bottom plate 4. A telescopic tube 39 is fixedly installed between the material box 31 and the discharge pipe 35. A guide groove 37 is opened inside the material box 31, and the bottom of the guide groove 37 is connected to the telescopic tube 39. The lowest point of the material box 31 is higher than the connection between the discharge pipe 35 and the telescopic tube 39.

[0041] In this embodiment, before screening, the seeds are placed in the material box 31. The seeds enter the telescopic tube 39 through the guide groove 37, and enter the discharge pipe 35 through the telescopic tube 39 under the action of gravity, and are discharged onto the first screen 21 through the discharge pipe 35. The telescopic tube 39 enables the discharge pipe 35 to be connected with the material box 31 through the telescopic tube 39 when it moves. When the discharge pipe 35 discharges the seeds, the screw 34 is driven to rotate by starting the motor 36. The rotation of the screw 34 drives the slider 33 and the discharge pipe 35 to move. The motor 36 is rotated forward and reversely, so that the discharge pipe 35 can move back and forth above the first screen 21, so that the seeds can fall evenly on each position on the first screen 21, thereby achieving a better screening effect.

[0042] Working principle: Before screening, the seeds are placed in the material box 31, and the seeds enter the telescopic tube 39 through the guide groove 37, and enter the discharge pipe 35 through the telescopic tube 39 under the action of gravity, and are discharged onto the first screen 21 through the discharge pipe 35. The telescopic tube 39 enables the discharge pipe 35 to be connected with the material box 31 through the telescopic tube 39 when it moves. When the discharge pipe 35 discharges seeds, the screw 34 is driven to rotate by starting the motor 36, and the rotation of the screw 34 drives the slider 33 and the discharge pipe 35 to move. The motor 36 is rotated forward and reversely, so that the discharge pipe 35 can move back and forth above the first screen 21, so that the seeds are discharged. The seeds can fall evenly on each position on the first sieve 21, thereby achieving a better screening effect; during screening, the seeds fall into the top of the first sieve 21, and the seeds roll on the first sieve 21. When rolling, the seeds with a size larger than the aperture of the first sieve 21 will fall downward onto the second sieve 22. Similarly, the seeds with a size smaller than the aperture of the second sieve 22 will fall onto the bottom plate 23. The seeds remaining on the first sieve 21 are the largest in size, the seeds remaining on the second sieve 22 are the second largest in size, and the seeds on the bottom plate 23 are the smallest in size. The three seeds of different sizes enter the three different collecting barrels 27 through the first, second and third discharge plates respectively, thereby realizing multi-stage screening of the seeds.
