[0030] It also includes:

[0031] A drive motor 4 is fixedly mounted on the frame 1. A rotating disk 5 is fixedly mounted on the output shaft of the drive motor 4. A drive rod 6 is eccentrically connected to the rotating disk 5 through a rotating shaft. One end of the drive rod 6 is hinged to the connecting frame 2.

[0032] Two sieve plates 7 are fixedly installed inside the connecting frame 2. A first guide frame 8 and a second guide frame 9 are fixedly installed on the upper and lower sides of the right side of the connecting frame 2, respectively. The sieve plates 7 on the upper and lower sides are fixedly connected to the first guide frame 8 and the second guide frame 9, respectively. The sieve hole diameter of the upper sieve plate 7 is larger than that of the lower sieve plate 7. The upper sieve plate 7 can screen out larger branches, leaves or impurities from soybean seeds.

[0033] The slag collection box 10 is fixedly installed on the frame 1 and is located below the connecting frame 2. Small impurities or poorly developed small seeds will fall through the sieve holes of the lower sieve plate 7 and fall into the slag collection box 10 for collection. The connecting frame 2 is equipped with a blockage removal mechanism 11 that cooperates with the two sieve plates 7.

[0034] The blockage removal mechanism 11 includes:

[0035] Two reciprocating lead screws 11-1 are respectively rotatably mounted on the front and rear sides of the connecting frame 2 via bearing seats. A movable block 11-2 is threadedly fitted onto each reciprocating lead screw 11-1. A connecting block 11-3 is fixedly mounted on the side wall of the movable block 11-2. The connecting block 11-3 is movably mounted within a strip groove 14 opened in the side wall of the connecting frame 2. Two bellows covers 16 are fixedly mounted within the strip groove 14, with one end of each bellows cover 16 fixedly connected to the connecting block 11-3. The accordion cover 16 can form a protective barrier inside the strip groove 14 to prevent seeds or impurities from splashing into the strip groove 14 during the soybean seed screening process, thus affecting the movement of the connecting block 11-3 inside the strip groove 14. Guide bars 17 are fixedly installed on the front and rear side walls of the connecting frame 2 on the upper and lower sides of the strip groove 14, and the guide bars 17 are movably inserted through the movable block 11-2. The guide bars 17 can provide auxiliary guidance for the movement of the movable block 11-2, thereby improving the movement stability of the movable block 11-2.

[0036] The movable rod 11-4 is movably disposed within the connecting frame 2, and the end of the movable rod 11-4 is fixedly connected to the connecting block 11-3.

[0037] A dual-axis motor 11-6 is fixedly mounted on the left side wall of the connecting frame 2. The two output shafts of the dual-axis motor 11-6 are respectively connected to two reciprocating screws 11-1 through a bevel gear pair. When the dual-axis motor 11-6 drives the reciprocating screws 11-1 on both sides to rotate synchronously using the bevel gear pair, the movable block 11-2 can drive the moving rod 11-4 to move back and forth in the connecting frame 2 through the connecting block 11-3, so that the two brush plates 11-5 can clean the blockages on the screen plates 7 on both sides respectively. A protective shell 13 is fixedly mounted on the left side wall of the connecting frame 2. The dual-axis motor 11-6 is located in the protective shell 13. The left end of the reciprocating screw 11-1 is rotatably inserted into the protective shell 13 through a bearing. The protective shell 13 can provide protection for the left end of the dual-axis motor 11-6 and the reciprocating screw 11-1 to prevent debris from interfering with the transmission of the bevel gear pair.

[0038] The high-efficiency cleaning mechanism 12 includes:

[0039] Movable bar 12-1 is movably disposed within movable rod 11-4, and the upper and lower sides of movable bar 12-1 are respectively fixedly connected to two brush plates 11-5;

[0040] Rotating rod 12-2 is rotatably inserted into movable rod 11-4 via bearing. One end of rotating rod 12-2 is movably inserted into movable bar 12-1. Two guide blocks 12-3 are fixedly installed on the inner ring wall of movable bar 12-1. The guide blocks 12-3 are movably installed in the reciprocating guide groove 15 opened on the ring side wall of rotating rod 12-2. The front end of rotating rod 12-2 passes through the front connecting block 11-3 and is fixedly sleeved with gear 12-4, and gear 12-4 is located in the front movable block 11-2.

[0041] Rack 12-5 is fixedly mounted on the front side wall of the connecting frame 2 above the strip groove 14. Rack 12-5 meshes with gear 12-4. During the reciprocating movement of brush plate 11-5, the meshing of gear 12-4 and rack 12-5 causes rotating rod 12-2 to rotate. The movement of guide block 12-3 in reciprocating guide groove 15 causes movable bar 12-1 to drive brush plate 11-5 to move back and forth, improving the cleaning effect and efficiency of brush plate 11-5 on screen plate 7.

[0042] When using this utility model, start the drive motor 4, drive the rotating disk 5 to rotate, and use the cooperation of the drive rod 6 and the connecting rod 3 to drive the connecting frame 2 to swing back and forth. The connecting frame 2 drives the screen plate 7 to swing. Then, pour the soybean seeds into the feeding hopper 18. The soybean seeds will fall onto the upper screen plate 7. Larger branches or impurities will move to the right through the swing of the upper screen plate 7 and be discharged through the first guide frame 8. The soybean seeds will fall down through the screen holes of the upper screen plate 7 onto the lower screen plate 7. With the swing of the lower screen plate 7 and its tilt to the right and down, the plump soybean seeds will move to the right on the lower screen plate 7 and be discharged through the second guide frame 9. Poorly developed small-diameter soybean seeds and small-volume impurities will pass through the screen holes of the lower screen plate 7 and fall into the slag collection box 10.

[0043] When the screen plate 7 becomes clogged, the dual-shaft motor 11-6 can be started. The dual-shaft motor 11-6 drives the reciprocating screws 11-1 on both sides to rotate synchronously through the transmission of the bevel gear pair, so that the movable block 11-2 can move back and forth on the reciprocating screw 11-1. The movable block 11-2 drives the moving rod 11-4 to move back and forth in the connecting frame 2 through the connecting block 11-3. The moving rod 11-4 drives the two brush plates 11-5 to move back and forth in the left and right through the movable bar 12-1, so as to achieve synchronous cleaning of the two screen plates 7. In addition, during this process, the meshing of the gear 12-4 and the rack 12-5 can also make the rotating rod 12-2 rotate. At this time, the guide block 12-3 will move in the reciprocating guide groove 15, so that the movable bar 12-1 can move back and forth in the moving rod 11-4. The moving rod 11-4 drives the brush plate 11-5 to move back and forth, so that the brush plate 11-5 can clean the screen plate 7 more efficiently.

[0044] Compared with the prior art, the beneficial effects of this utility model are:

[0045] 1. With the cooperation of the blockage removal mechanism 11, the dual-shaft motor 11-6 drives the reciprocating screw 11-1, causing the movable block 11-2 to move back and forth, and through the connecting block 11-3, it drives the moving rod 11-4 and the brush plate 11-5 to move back and forth, so as to achieve synchronous cleaning of the two screen plates 7.

[0046] 2. With the cooperation of the high-efficiency cleaning mechanism 12, the brush plate 11-5 can simultaneously move back and forth to the front and back sides while cleaning the screen plate 7 from left to right, thereby improving the cleaning efficiency and effect of the brush plate 11-5 on the screen plate 7.

[0047] 3. The bellows cover 16 can form a protective barrier inside the strip groove 14 to prevent seeds or impurities from splashing into the strip groove 14 during the soybean seed screening process, thus affecting the movement of the connecting block 11-3 inside the strip groove 14;

[0048] 4. The guide bar 17 can provide auxiliary guidance for the movement of the movable block 11-2, thereby improving the movement stability of the movable block 11-2.
