[0023] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. The following will refer to the accompanying drawings Figures 1 - 4 and describe the present utility model in detail in conjunction with the embodiments.

[0024] A seed sorting device for forage grass planting in animal husbandry includes a housing 1. The bottom wall of the housing 1 is in a funnel-shaped structure, and a discharge pipe 12 is provided at its bottom. An electromagnetic valve 13 is provided inside the discharge pipe 12. The opposite side walls of the housing 1 are respectively provided with discharge ports 15, and a feed hopper 16 is provided through the top wall of the housing 1.

[0025] The forage grass seeds enter the interior of the housing 1 from the feed hopper 16, and after being filtered by the coarse filter screen 2, dusted by the dust collection structure 8, and filtered by the fine filter screen 11, the relatively thick and plump seeds are selected. By opening the electromagnetic valve 13, the small stones or broken forage grass seeds screened out by the fine filter screen 11 can be discharged from the discharge pipe 12.

[0026] The housing 1 is inclined with a coarse filter screen 2. A stirring rod 7 is rotatably provided above the coarse filter screen 2. A connecting plate 3 with an inclination direction opposite to that of the coarse filter screen 2 is fixedly provided at the inclined lower end of the coarse filter screen 2. Both the coarse filter screen 2 and the connecting plate 3 are fixedly provided on the side wall of the housing 1. A servo motor 17 and a vibration motor 18 are respectively provided on the bottom walls of the coarse filter screen 2 and the fine filter screen 11. The stirring rod 7 includes a stirring shaft 19 provided at the output end of the servo motor 17, and stirring paddles 20 are fixedly provided on the outer wall of the stirring shaft 19.

[0027] When the forage grass seeds fall above the coarse filter screen 2, the servo motor 17 is started to drive the stirring shaft 19 and the stirring paddles 20 to rotate, stirring the forage grass seeds, accelerating the filtering speed of the forage grass seeds by the coarse filter screen 2, and preventing them from piling up on the surface of the coarse filter screen 2. Since the connection between the coarse filter screen 2 and the connecting plate 3 is at a low position, the filtered weeds or large stones etc. slide to a lower place.

[0028] The lower inclined end of the connecting plate 3 is provided with a through hole 4. A baffle 5 is movably arranged below the through hole 4. A vertical plate 24 is fixedly arranged on the bottom wall of the connecting plate 3. The number of reciprocating lead screws 6 is two, and they are both rotatably arranged between the vertical plate 24 and the side wall of the L-shaped plate 21. The reciprocating lead screws 6 both penetrate through the vertical plate 24 and are fixedly provided with synchronous gears 25. The two synchronous gears 25 are movably connected by a gear belt 26. One of the synchronous gears 25 is arranged at the output end of the micro motor 27. The size specification of the baffle 5 is larger than that of the through hole 4.

[0029] Start the micro motor 27 to drive the synchronous gear 25 to rotate. Under the synchronous action of the gear belt 26, the two synchronous gears 25 rotate simultaneously, and then drive the reciprocating lead screws 6 to rotate. Since the baffle 5 is slidably arranged on the outer periphery of the reciprocating lead screw 6, the rotation of the reciprocating lead screw 6 drives the baffle 5 to move along the reciprocating lead screw 6. When there is weed accumulation, move the baffle 5 to expose the through hole 4. Weeds and stones pass through the through hole 4. Since a guide plate 28 is inclinedly arranged below the reciprocating lead screw 6, the inclined lower end of the guide plate 28 penetrates through one of the discharge ports 15. Weeds and stones fall into the lower guide plate 28 along the through hole 4 and finally fall into the miscellaneous material box 23 along the discharge port 15.

[0030] A dust suction structure 8 is arranged below the baffle 5. The dust suction structure 8 includes a blower 9 and a dust suction hood 10. An L-shaped plate 21 is fixedly arranged below the connecting plate 3. The blower 9 is fixedly arranged at the bottom of the L-shaped plate 21. Two conveying pipes 22 are respectively arranged at both ends of the blower 9. A number of dust suction hoods 10 are communicated with one end of the conveying pipe 22. The dust suction ports of the dust suction hoods 10 are facing the lower part of the coarse filter screen 2. The other conveying pipe 22 penetrates through the side wall of the housing 1 and is communicated with the miscellaneous material box 23.

[0031] When the screened forage seeds fall along the coarse filter screen 2 into the lower fine filter screen 11, start the blower 9 and adjust the wind speed according to the weight of the forage seeds to a wind speed that can suck up dust and grass debris but will not suck up the good and heavy forage seeds. Start the blower 9 to drive the dust suction hoods 10 to suck up dust, grass debris, etc. into the conveying pipe 22 and finally gather inside the miscellaneous material box 23.

[0032] A fine filter screen 11 is arranged below the dust suction structure 8 in a vibrating manner. The fine filter screen 11 is inclinedly arranged, and a number of support blocks 29 are arranged below it. Elastic members 30 are arranged on the top walls of the support blocks 29 and the bottom wall of the other discharge port 15. The bottom wall of the fine filter screen 11 is fixedly connected to the top ends of the elastic members 30. A protective plate 14 is arranged on the side wall of the fine filter screen 11. The inclined lower end of the fine filter screen 11 penetrates through the other discharge port 15, and a seed box 31 is arranged at its inclined lower end.

[0033] Start the vibration motor 18, which drives the fine filter screen 11 to vibrate up and down under the elastic action of the elastic member 30, driving the forage seeds falling into it to be quickly screened. Small stones, dust that have not been completely sucked in the dust collection structure 8, and some broken forage seeds are filtered below the fine filter screen 11, and the remaining plump forage seeds fall into the seed box 31 along the fine filter screen 11 for storage.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
