[0002] Caragana korshinskii is an important shrub for soil and water conservation and sand fixation afforestation. It possesses advantages such as drought resistance, cold resistance, and heat resistance, and can grow normally in extremely fertile, shifting sand dunes and inter-dune lowlands with a sand moisture content of 2-3%, as well as fixed and semi-fixed sand dunes. It can even grow normally in years with only 100 mm of rainfall. The roots, flowers, and seeds of Caragana korshinskii can all be used medicinally. It flowers from May to June and fruits in July. The pods are oval or kidney-shaped, inflated or flattened, with pointed tips and oval or spherical seeds. Manually harvesting Caragana korshinskii seeds is labor-intensive and time-consuming.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Reference Figure 1-5 The present invention provides a device for collecting Caragana korshinskii seeds, comprising:
[0028] The outer casing 1 is detachably connected to the power equipment. The outer casing 1 has an inlet 2 and an outlet 3. The outer casing 1 is fixedly connected to two base supports 4, which are symmetrically arranged and have a channel between them.
[0029] A toggle assembly is located inside the housing 1. The toggle assembly includes a mounting plate 5, which is movably connected to the housing 1. A rotating shaft 6 is rotatably connected to the mounting plate 5. A fixed plate 7 is fixedly connected to the rotating shaft 6. Several levers 8 are fixedly connected to the fixed plate 7. A first motor 9 is fixedly connected to the mounting plate 5. The first motor 9 and the rotating shaft 6 are connected by a reciprocating transmission mechanism.
[0030] The suction assembly includes several blowers 10, which are fixedly connected inside the housing 1. The air inlet end of the blower 10 is fixedly connected to an air inlet pipe 11, and a discharge port 12 is provided on the air inlet pipe 11.
[0031] This device moves under the drive of a power source. The outer shell 1 is conveniently connected to the power source. The base 4 can be used to store Caragana seeds. After the Caragana seeds fall off, they will fall onto the base 4. The channel is used for the passage of Caragana plants. In use, this device moves towards the Caragana plants under the drive of the power source. The Caragana plants enter the interior of the outer shell 1 through the inlet 2. At the same time, the Caragana plants enter the channel between the two bases 4. The first motor 9 drives the rotating shaft 6 to rotate through the reciprocating transmission mechanism. The rotating shaft 6 rotates alternately in the forward and reverse directions. The rotating shaft 6 drives the fixed plate 7 to rotate. The fixed plate 7 drives the lever 8 to move. The lever 8 is used to move the Caragana, causing the Caragana seeds to fall. The blower 10 generates suction. The air inlet pipe 11 is set on both sides of the lever 8, which can accelerate the movement of the Caragana seeds to the sides, making it easier for the Caragana seeds to fall. When the Caragana seeds enter the air inlet pipe 11, they can be discharged through the discharge port 12. As this device moves, the Caragana plants finally leave the outer shell 1 from the outlet 3.
[0032] The scheme is further optimized. The reciprocating transmission mechanism includes a first turntable 13 and a second turntable 14. The first turntable 13 is fixedly connected to the output end of the first motor 9. The second turntable 14 is fixedly connected to the side of the rotating shaft 6 away from the mounting plate 5. The first turntable 13 is rotatably connected to a first connecting rod 15. The end of the first connecting rod 15 away from the first turntable 13 is rotatably connected to a second connecting rod 16. The end of the second connecting rod 16 away from the first connecting rod 15 is rotatably connected to a third connecting rod 17. The third connecting rod 17 is rotatably connected to the second turntable 14. A limit tube 18 is fixedly connected to the mounting plate 5. The second connecting rod 16 is slidably disposed within the limit tube 18.
[0033] The first motor 9 drives the first turntable 13 to rotate, the first turntable 13 drives the first connecting rod 15 to move, the first connecting rod 15 drives the second connecting rod 16 to move, the second connecting rod 16 drives the third connecting rod 17 to move, the third connecting rod 17 drives the second turntable 14 to rotate, the second turntable 14 drives the rotating shaft 6 to rotate, and the limiting tube 18 is used to limit the position of the second connecting rod 16. The first turntable 13, the second turntable 14 and the second connecting rod 16 are all arranged on a straight line.
[0034] In a further optimized design, a first pin 19 is fixedly connected to the first turntable 13. First through holes are opened at both ends of the first connecting rod 15, and the first pin 19 passes through these holes, rotating within them. Second through holes are opened at both ends of the second connecting rod 16, rotating through them via a second pin 20. Third through holes are opened at both ends of the third connecting rod 17, rotating through them via a third pin 21. A fourth pin 22 is fixedly connected to the second turntable 14, passing through the third through hole and rotating within it. The diameter of the first turntable 13 is smaller than that of the second turntable 14, and the distance from the first pin 19 to the center of the first turntable 13 is smaller than the distance from the fourth pin 22 to the center of the second turntable 14.
[0035] The first turntable 13 is rotatably connected to the first connecting rod 15 via the first pin 19. The first connecting rod 15 is rotatably connected to the second connecting rod 16 via the second pin 20. The second connecting rod 16 is rotatably connected to the third connecting rod 17 via the third pin 21. The third connecting rod 17 is rotatably connected to the second turntable 14 via the fourth pin 22.
[0036] Since the distance from the first pin 19 to the center of the first turntable 13 is less than the distance from the fourth pin 22 to the center of the second turntable 14, when the first turntable 13 drives the first connecting rod 15 to move to the distance between the closest and furthest points from the second turntable 14 (in the same direction as the line connecting the centers of the first turntable 13 and the second turntable 14), it is less than the distance from the fourth pin 22 to the center of the second turntable 14. Therefore, the range of movement of the fourth pin 22 when it drives the third connecting rod 17 will not exceed 180°. In other words, the range of rotation of the fourth pin 22 and the third connecting rod 17 will not exceed half a turn, and it will reciprocate within this range. Therefore, the lever 8 will not stir or entangle the twigs, but will cause the twigs to swing, which is beneficial for the seeds to fall off.
[0037] The design is further optimized by fixing a first stop 23 to the mounting plate 5 and a second stop 24 to the fixing plate 7. Both the first stop 23 and the second stop 24 are provided with locking holes. A torsion spring 25 is passed through the rotating shaft 6, and both ends of the torsion spring 25 are inserted into the locking holes.
[0038] The first stop 23 and the second stop 24 are used to fix the torsion spring 25, which can provide torsional rebound force to prevent jamming when the second link 16 and the third link 17 are in a straight line.
[0039] The scheme is further optimized. Several connecting plates 26 are fixedly connected inside the outer shell 1. The blower 10 is fixedly connected to the connecting plates 26. An exhaust pipe 27 is fixedly connected to the air outlet end of the blower 10. The exhaust pipe 27 extends out of the outer shell 1. A guide plate 28 is fixedly connected to the end of the air inlet pipe 11 away from the blower 10. A storage tank 29 is fixedly connected to the air inlet pipe 11. The storage tank 29 is connected to the air inlet pipe 11. A discharge port 12 is opened on the storage tank 29. A sealing cover 30 is detachably connected to the discharge port 12. A filter plate 31 is fixedly connected inside the air inlet pipe 11.
[0040] The air generated by the blower 10 is discharged through the exhaust pipe 27. The blower 10 generates suction, and the airflow enters from the inlet pipe 11. The size of the guide plate 28 is larger than that of the inlet pipe 11, which facilitates the entry of the Caragana seeds into the guide plate 28. The storage tank 29 is used to store the Caragana seeds. When the Caragana seeds are sucked in, they can fall into the storage tank 29. The Caragana seeds can be taken out by opening the sealing cover 30. The filter plate 31 can prevent impurities from entering the blower 10.
[0041] The scheme is further optimized. Several first electric telescopic rods 32 are fixedly connected to the mounting plate 5. The fixed end of the first electric telescopic rod 32 is fixedly connected to the outer shell 1. The output end of the first electric telescopic rod 32 is fixedly connected to the mounting plate 5. Several through holes are opened on the mounting plate 5. Several guide posts 33 are fixedly connected to the outer shell 1. The guide posts 33 are inserted into the through holes and slide within the through holes. A limit plate 34 is fixedly connected to the end of the guide post 33 away from the outer shell 1.
[0042] The first electric telescopic rod 32 drives the mounting plate 5 to move up and down. The guide post 33 is in the through hole, which allows the mounting plate 5 to move up and down along the guide post 33. The limiting plate 34 prevents the mounting plate 5 from detaching from the guide post 33. The up and down movement of the mounting plate 5 can adjust the height of the lever 8.
[0043] The scheme is further optimized by fixing several bases 35 on the base 4, fixing a second electric telescopic rod 36 on the base 35, the second electric telescopic rod 36 is inclined upward, and the output end of the second electric telescopic rod 36 is fixedly connected to a top plate 37, which is arc-shaped.
[0044] The base 35 is used to fix the second electric telescopic rod 36. The second electric telescopic rod 36 drives the top plate 37 to move. The second electric telescopic rods 36 on the base 4 are set opposite each other. Since most of the Caragana plants are in a fully grown state, the top plates 37 on both sides can lift the Caragana plants, which is conducive to the lever 8 being turned.
[0045] The scheme is further optimized by fixing a plastic plate 38 on the base 4. The plastic plate 38 is inclined, curved, and made of flexible material. The distance between the two plastic plates 38 near the entrance 2 is greater than the distance between the two plastic plates 38 near the exit 3.
[0046] When the Caragana plant enters the channel between the two base supports 4, the plastic plate 38 can first gradually straighten the bottom of the Caragana plant.
[0047] The design was further optimized so that the rotating shaft 6 and the mounting plate 5 are rotatably connected by a planar thrust bearing 39.
[0048] The planar thrust bearing 39 makes the rotation of the shaft 6 and the mounting plate 5 more flexible.
[0049] The design is further optimized by having several movable wheels 40 rotatably connected to the outer shell 1, and several connecting rings 41 fixedly connected to the outer shell 1. The outer shell 1 is detachably connected to the power equipment through the connecting rings 41. A cleaning port 42 is provided on the outer shell 1, and a door panel is rotatably connected to the cleaning port 42.
[0050] The movable wheel 40 facilitates the movement of this device, the connecting ring 41 facilitates the connection of the power equipment to this device, and the cleaning port 42 cleans the seeds inside. The cleaning port 42 is located on the side wall of the outer casing 1, between the two movable wheels 40, and does not interfere with the movable wheels 40 when the door is opened or closed.
[0051] The device is used by connecting it to a power unit via a connecting ring 41. Driven by the power unit, the device moves towards the *Caragana korshinskii* plant. The plant enters the outer casing 1 through inlet 2, simultaneously entering the channel between the two base supports 4. As the plant enters inlet 2, the plastic plate 38 gradually straightens the bottom of the plant. Then, the second electric telescopic rod 36 pushes out the top plate 37, lifting the plant and facilitating the movement of the lever 8. The first motor 9 drives the first turntable 13 to rotate, which in turn drives the first connecting rod 15, which in turn drives the second connecting rod. 16 moves, the second link 16 drives the third link 17 to move, the third link 17 drives the second turntable 14 to rotate, the second turntable 14 drives the rotating shaft 6 to rotate. During the movement, the fourth pin 22 drives the third link 17 to rotate within a range of no more than half a turn, and moves back and forth within this range. The movement of the lever 8 will cause the Caragana twigs to swing. After the Caragana twig seeds fall off, they will fall onto the base 4. The first electric telescopic rod 32 can drive the mounting plate 5 to move up and down, thereby adjusting the height of the lever 8. When it is necessary to clean the Caragana twig seeds, open the door panel, then open the sealing cover 30 on the storage slot 29, and take out the Caragana twig seeds.
