[0038] See also Figure 1-11 The present invention provides a technical solution: a pollination device used for corn seed production, comprising a first bag body 1, a second bag body 2, a first pipeline, a pumping unit and a second pipeline 3, wherein the first bag body 1 is used to be put on a corn male ear, and the second bag body 2 is used to be put on a corn female ear, the first pipeline connects the first bag body 1 and the second bag body 2, the pumping unit is arranged on the first pipeline and is used to pump the air in the first bag body 1 into the second bag body 2 through the first pipeline, and the second pipeline 3 is used to introduce the air in the second bag body 2 into the first bag body 1.

[0039] The use principle of the pollination device for corn seed production described in the present invention is: before the corn tassel blooms, the bag mouth of the first bag body 1 is facing downward and the first bag body 1 is put on the corn tassel, and the bag mouth of the second bag body 2 is facing obliquely downward and the second bag body 2 is put on the corn female ear. Then, the bag mouth of the first bag body 1 is tied and fixed on the main axis of the corn tassel with a rope, so that the bag mouth of the first bag body 1 is in a closed state, so that the inner cavity of the first bag body 1 is in a nearly sealed state. Then, the bag mouth of the second bag body 2 is tied and fixed to the lower part of the corn female ear with a rope, so that the bag mouth of the second bag body 2 is in a closed state, so that the inner cavity of the second bag body 2 is in a nearly sealed state. When the bag mouth of the first bag body 1 is closed, and when the bag mouth of the second bag body 2 is closed, the first bag body 1 and the second bag body 2 are both in a bulging state.

[0040] The pumping unit can pump the air in the first bag body 1 into the second bag body 2 through the first pipeline. During the process of the air in the first bag body 1 entering the second bag body 2, the air in the second bag body 2 can be introduced into the first bag body 1 through the second pipeline 3, so that the air can circulate between the first bag body 1 and the second bag body 2.

[0041] After the male corn tassel blooms, the corn pollen can flow with the air and circulate between the first bag body 1 and the second bag body 2, and part of the pollen can adhere to the filaments of the female corn tassel to achieve pollination of the female corn tassel. In addition, the first bag body 1 and the second bag body 2 are both in a closed state, and when the corn pollen circulates between the first bag body 1 and the second bag body 2 with the air, it is not easy to be discharged outside the first bag body 1 and the second bag body 2, so that the pollen concentration in the first bag body 1 and the second bag body 2 is high, and a better pollination effect can be achieved.

[0042] Since the first bag body 1 and the second bag body 2 are in a closed state, corn pollen in the outside air is not easy to enter the first bag body 1 and the second bag body 2, which can greatly reduce the possibility of pollen from other plants sticking to the filaments of the corn plant, reduce the possibility of gene mixing, and reduce the possibility of affecting the purity and genetic characteristics of the seeds.

[0043] In this embodiment, the pumping part includes an insertion rod 4, a cylinder 5, a piston 6 and a first driving part. The lower end of the insertion rod 4 is used to be inserted and fixed in the soil. The cylinder 5 is fixed on the insertion rod 4. One end of the cylinder 5 is closed and the other end is open. The piston 6 is slidably fitted in the cylinder 5. The first driving part is used to drive the piston 6 to reciprocate along the axis direction of the cylinder 5.

[0044] The first pipeline includes a first air pipe 7, a second air pipe 8, a first one-way valve 9 and a second one-way valve 10. One end of the first air pipe 7 is fixedly connected to the bag wall of the first bag body 1 and is connected to the inner cavity of the first bag body 1. The other end of the first air pipe 7 is fixedly connected to the side wall of the one end of the cylinder 5 and is connected to the inner cavity of the cylinder 5. One end of the second air pipe 8 is fixedly connected to the side wall of the one end of the cylinder 5 and is connected to the inner cavity of the cylinder 5. The other end of the second air pipe 8 is fixedly connected to the bag wall of the second bag body 2 and is connected to the inner cavity of the second bag body 2. The first one-way valve 9 is arranged on the first air pipe 7 and is used to prevent air from flowing from the cylinder 5 into the first bag body 1. The second one-way valve 10 is arranged on the second air pipe 8 and is used to prevent air from flowing from the second bag body 2 into the cylinder 5.

[0045] After the first end bag body is put on the male ear of corn and the second bag body 2 is put on the female ear of corn, the lower end of the insertion rod 4 is inserted and fixed in the soil. Since the cylinder 5 is fixed on the insertion rod 4, the cylinder 5 can be fixed above the ground at this time.

[0046] When the first driving unit drives the piston 6 to move toward the one end of the cylinder 5, under the action of the first one-way valve 9, the air in the cylinder 5 cannot flow into the first bag body 1 through the first air pipe 7, and the air in the cylinder 5 enters the second bag body 2 through the second air pipe 8; when the first driving unit drives the piston 6 to move toward the other end of the cylinder 5, under the action of the second one-way valve 10, the air in the second bag body 2 cannot flow into the cylinder 5 through the second air pipe 8, and the air in the first bag body 1 enters the cylinder 5 through the first air pipe 7. In the process of the first driving unit driving the piston 6 to reciprocate along the axis of the cylinder 5, the air in the first bag body 1 can be pumped into the second bag body 2. With this structure, the pumping unit can pump the air in the first bag body 1 into the second bag body 2 through the first pipeline.

[0047] In this embodiment, the second pipe 3 is a third air pipe, one end of which is fixedly connected to the bag wall of the first bag body 1 and communicates with the inner cavity of the first bag body 1, and the other end of which is fixedly connected to the bag wall of the second bag body 2 and communicates with the inner cavity of the second bag body 2. With this structure, the second pipe 3 can introduce the air in the second bag body 2 into the first bag body 1.

[0048] In this embodiment, the first driving part includes a vertical rod 11, a wind shield 12, a piston rod 13, a first baffle 14 and a first coil spring 15. The vertical rod 11 is located on one side of the insertion rod 4. The vertical rod 11 is rotatably connected to the insertion rod 4. The rotation centerline of the vertical rod 11 is arranged in the horizontal direction. The wind shield 12 is fixed to the upper end of the vertical rod 11. One end of the piston rod 13 is fixedly connected to the piston 6. The side of the first baffle 14 facing the cylinder 5 is fixedly connected to the other end of the piston rod 13. The side of the first baffle 14 facing away from the cylinder 5 abuts the vertical rod 11. The rotation centerline of the vertical rod 11 is located between the upper end and the lower end of the first baffle 14. The first coil spring 15 is located in the cylinder 5. One end of the first coil spring 15 abuts against the end wall of the one end of the cylinder 5, and the other end abuts against the piston 6.

[0049] When natural wind blows onto the wind shield 12 , it will cause thrust to the wind shield 12 , and the wind shield 12 can swing toward the direction where the cylinder 5 is located or swing away from the direction where the cylinder 5 is located under the action of wind force and drive the vertical rod 11 to rotate.

[0050] When the wind shield 12 is swung toward the direction of the cylinder 5 under the action of wind, the vertical rod 11 can be rotated from a vertical state to a state in which the upper end is inclined toward the cylinder 5. During the process of the vertical rod 11 rotating from a vertical state to a state in which the upper end is inclined toward the cylinder 5, the portion of the vertical rod 11 located on the upper side of the rotation centerline can squeeze the first baffle 14 toward the cylinder 5, so that the first baffle 14 faces the cylinder 5. The first baffle 14 can push the piston rod 13 and the piston 6 to move toward the one end of the cylinder 5, and the piston 6 compresses the first coil spring 15.

[0051] When the wind shield 12 is swung toward the direction where the cylinder 5 is located under the action of wind, the vertical rod 11 can be rotated from a vertical state to a state where the upper end is inclined away from the cylinder 5. During the process of the vertical rod 11 rotating from a vertical state to a state where the upper end is inclined away from the cylinder 5, the portion of the vertical rod 11 located below the rotation centerline can squeeze the first baffle 14 toward the cylinder 5, so that the first baffle 14 moves toward the cylinder 5. The first baffle 14 can push the piston rod 13 and the piston 6 to move toward the one end of the cylinder 5, and the piston 6 compresses the first coil spring 15.

[0052] After the natural wind stops, the first coil spring 15 can be elastically reset. During the elastic reset of the first coil spring 15, the first coil spring 15 can push the piston 6 toward the other end of the cylinder 5 to reset the piston 6, the piston rod 13 and the first baffle 14.

[0053] With this structure, the first driving unit can drive the piston 6 to reciprocate along the axial direction of the cylinder 5 .

[0054] The first driving unit can drive the piston 6 to reciprocate along the axial direction of the cylinder 5 by relying on the wind force of natural wind and the elastic force of the first coil spring 15, and can pump the air in the first bag body 1 into the second bag body 2 through the first pipeline by relying on the wind force of natural wind and the elastic force of the first coil spring 15. When the air in the first bag body 1 is pumped into the second bag body 2 through the first pipeline, no electricity and manpower are consumed.

[0055] In this embodiment, the first driving part further includes a crossbar 16, a rotating column 17, a stop ring 18 and a connecting rod 19, one end of the crossbar 16 is fixedly mounted on the insertion rod 4, the other end of the crossbar 16 is recessed inward to form a circular groove, the rotating column 17 is rotatably fitted in the circular groove, the stop ring 18 is fixedly mounted in the circular groove, one end of the connecting rod 19 is fixedly connected to the rotating column 17, and the other end of the connecting rod 19 is fixedly connected to the vertical rod 11 after passing through the ring hole of the stop ring 18. With this structure, the vertical rod 11 can be rotatably connected to the insertion rod 4.

[0056] The limiting ring 18 can limit the rotating column 17, so that the rotating column 17 cannot fall out of the circular groove, and the rotating column 17 and the connecting rod 19 cannot be separated from the cross bar 16, and further the vertical rod 11 cannot be separated from the cross bar 16, which can improve the structural stability of the pollination device used for corn seed production described in the present invention.

[0057] In this embodiment, the pumping part also includes a connecting plate 20, one end of the connecting plate 20 is fixedly connected to the other end of the cross bar 16, and the other end of the connecting plate 20 is fixedly connected to the cylinder 5. With this structure, the cylinder 5 can be fixed on the insertion rod 4.

[0058] In this embodiment, a shaking part for shaking the corn plant stem is also included. The shaking part can shake the corn plant stem. After the corn blooms, the shaking of the corn plant stem by the shaking part makes it easier for the pollen on the corn flower to separate from the corn flower, which can further increase the pollen concentration in the first bag body 1 and the second bag body 2, and can further improve the pollination effect.

[0059] In this embodiment, the shaking part includes a support plate 21, a sliding rod 22 and a second driving part. The support plate 21 is fixed on the insertion rod 4. Specifically, the support rod is fixedly connected to the insertion rod 4 through a fixing rod 23. The sliding rod 22 is horizontally arranged. The sliding rod 22 is connected to the support plate 21 in a manner that it can slide along its length direction. One end of the sliding rod 22 extends out of the edge of the support plate 21. The one end of the sliding rod 22 is used to be fixed on the corn plant stem. The second driving part is used to drive the sliding rod 22 to slide back and forth. Specifically, the second driving part is used to drive the sliding rod 22 to slide back and forth along the length direction of the sliding rod 22.

[0060] When the lower end of the insertion rod 4 is inserted and fixed in the soil, one side of the one end of the sliding rod 22 is made to abut against the corn plant stem. After the lower end of the insertion rod 4 is inserted and fixed in the soil, the corn plant stem is tied and fixed to the one end of the sliding rod 22 by a rope. The sliding rod 22 is driven to slide back and forth by the second driving part, and the sliding rod 22 can drive the corn plant stem to shake. With this structure, the shaking part can shake the corn plant stem.

[0061] In this embodiment, the shaking part further includes a fixed column 24 and a sleeve 25, wherein the fixed column 24 is fixed on the support plate 21, the sleeve 25 is fixed on the fixed column 24, and the sliding rod 22 is slidably fitted in the sleeve 25.

Specifically, the driving assembly is used to drive the sliding plate 26 to slide horizontally reciprocatingly perpendicular to the length direction of the sliding rod 22, one end of the second coil spring 27 is fixedly connected to the sliding rod 22, and the other end of the second coil spring 27 is fixedly connected to the supporting plate 21, the second coil spring 27 pulls the sliding rod 22 toward the sliding plate 26 so that the other end of the sliding rod 22 abuts against the sliding plate 26, and the pushing part is provided on the sliding plate 26, and the pushing part is used to push the sliding rod 22 when it moves with the sliding plate 26 and passes the other end of the sliding rod 22, so that the sliding rod 22 moves back to the sliding plate 26.

[0063] The driving assembly drives the sliding plate 26 to slide horizontally and reciprocatingly perpendicular to the length direction of the sliding rod 22, and the sliding plate 26 drives the pushing portion to move reciprocatingly. When the pushing portion passes the other end of the sliding rod 22, the pushing portion pushes the sliding rod 22, causing the sliding rod 22 to move away from the sliding plate 26, and the second coil spring 27 is further compressed. After the pushing portion passes the other end of the sliding rod 22, the pushing portion is separated from the sliding rod 22, and the second coil spring 27 is elastically reset. The second coil spring 27 pushes the sliding rod 22 toward the sliding plate 26, causing the other end of the sliding rod 22 to abut against the sliding plate 26 again. With this structure, the second driving portion can drive the sliding rod 22 to slide reciprocatingly.

[0064] In this embodiment, the shaking part also includes a slide rail 28, a slider 29 and a slide groove. The slide rail 28 is fixed on the support plate 21.

[0069] When the wind shield 12 is swung toward the direction of the cylinder 5 under the action of wind, the vertical rod 11 is rotated from a vertical state to a state in which the upper end is inclined toward the cylinder 5. During the process of the vertical rod 11 rotating from a vertical state to a state in which the upper end is inclined toward the cylinder 5, the portion of the vertical rod 11 located below the rotation centerline can press the second baffle 33 toward the vertical plate 32, so that the second baffle 33 moves toward the vertical plate 32. The second baffle 33 can drive the sliding plate 26 to slide toward the vertical plate 32, and the third coil spring 34 is compressed.

[0070] When the wind shield 12 is swung toward the direction where the cylinder 5 is located under the action of wind, the vertical rod 11 is rotated from a vertical state to a state where the upper end is inclined away from the cylinder 5. During the process of the vertical rod 11 rotating from a vertical state to a state where the upper end is inclined away from the cylinder 5, the portion of the vertical rod 11 located on the upper side of the rotation centerline can press the second baffle 33 toward the vertical plate 32, so that the second baffle 33 moves toward the vertical plate 32. The second baffle 33 can drive the sliding plate 26 to slide toward the vertical plate 32, and the third coil spring 34 is compressed.

[0071] After the natural wind stops, the third coil spring 34 can be elastically reset. During the elastic reset of the third coil spring 34, the third coil spring 34 can push the second baffle plate 33 and the sliding plate 26 away from the vertical plate 32, and the second baffle plate 33 and the sliding plate 26 can slide away from the vertical plate 32 and reset.

[0072] With this structure, the driving assembly can drive the sliding plate 26 to slide back and forth.

[0073] The second driving unit can drive the sliding plate 26 to slide back and forth by relying on the wind force of natural wind and the elastic force of the third coil spring 34. When driving the sliding plate 26 to slide back and forth, no electricity and manpower are consumed, that is, no electricity and manpower are consumed when driving the sliding rod 22 to slide back and forth, that is, no electricity and manpower are consumed when shaking the corn plant stalks.

[0074] In this embodiment, a cavity 35 is formed in the sliding plate 26 , and a through hole 36 is formed inwardly on the side of the sliding plate 26 facing the sliding rod 22 , and the through hole 36 is connected to the cavity 35 ;

[0075] The pushing portion includes a rotating plate 37 and a fourth coil spring 38, one end of the rotating plate 37 is rotatably arranged in the cavity 35, the rotating plate 37 is located on the side of the sliding rod 22 away from the vertical plate 32, and the other end of the rotating plate 37 passes through the through hole 36 to the outside of the through hole 36, and the rotating plate 37 can resist the vertical hole wall of the through hole 36 close to the vertical plate 32 after swinging toward the vertical plate 32 by a certain angle, and the rotating plate 37 can also resist the vertical hole wall of the through hole 36 away from the vertical plate 32 after swinging away from the vertical plate 32 by a certain angle. The fourth coil spring 38 is two, and the two fourth coil springs 38 are respectively arranged on two opposite sides of the rotating plate 37, and the fourth coil spring 38 is arranged horizontally, one end of the fourth coil spring 38 is fixedly connected to the side wall of the accommodating cavity, and the other end of the fourth coil spring 38 is fixedly connected to the rotating plate 37.

[0076] When the sliding plate 26 slides toward the vertical plate 32, after the sliding plate 26 slides a certain distance toward the vertical plate 32, the side of the rotating plate 37 facing the vertical plate 32 will laterally abut the other end of the sliding rod 22. When the sliding plate 26 continues to move, under the squeezing action of the sliding rod 22, the other end of the rotating plate 37 will swing away from the vertical plate 32, and the fourth coil spring 38 located on the side of the rotating plate 37 facing away from the vertical plate 32 is gradually compressed, and the fourth coil spring 38 located on the side of the rotating plate 37 facing the vertical plate 32 is gradually stretched. After the sliding plate 26 continues to move a certain distance, the side of the rotating plate 37 facing away from the vertical plate 32 abuts against the vertical hole wall of the through hole 36 away from the vertical plate 32. At this time, the rotating plate 37 cannot continue to swing. As the sliding plate 26 continues to slide, the side of the rotating plate 37 facing the vertical plate 32 can push the other end of the sliding rod 22 away from the sliding plate 26, so that the sliding rod 22 moves away from the sliding plate 26, and the second coil spring 27 is compressed. After the rotating plate 37 moves with the sliding plate 26 to the other end of the sliding rod 22, the second coil spring 27 is elastically reset and pushes the sliding rod 22 toward the sliding plate 26. After the sliding rod 22 moves a certain distance toward the sliding plate 26, the other end of the sliding rod 22 suddenly hits the sliding plate 26, and the other end of the sliding rod 22 is restored to the state of abutting against the sliding plate 26. After the rotating plate 37 moves with the sliding plate 26 to the other end of the sliding rod 22, the vertical plate 32 will also swing and reset under the elastic reset action of the two fourth coil springs 38.

[0077] When the sliding plate 26 slides away from the vertical plate 32, after the sliding plate 26 slides a certain distance away from the vertical plate 32, the side of the rotating plate 37 facing away from the vertical plate 32 will laterally abut the other end of the sliding rod 22. When the sliding plate 26 continues to move, under the squeezing action of the sliding rod 22, the other end of the rotating plate 37 will swing toward the vertical plate 32, and the fourth coil spring 38 located on the side of the rotating plate 37 facing the vertical plate 32 is gradually compressed, and the fourth coil spring 38 located on the side of the rotating plate 37 facing away from the vertical plate 32 is gradually stretched. After the sliding plate 26 continues to move a certain distance, the side of the rotating plate 37 facing the vertical plate 32 abuts against the vertical hole wall of the through hole 36 close to the vertical plate 32. At this time, the rotating plate 37 cannot continue to swing. As the sliding plate 26 continues to slide, the side of the rotating plate 37 facing away from the vertical plate 32 can push the other end of the sliding rod 22 away from the sliding plate 26, so that the sliding rod 22 moves away from the sliding plate 26, and the second coil spring 27 is compressed. After the rotating plate 37 moves with the sliding plate 26 to the other end of the sliding rod 22, the second coil spring 27 is elastically reset and pulls the sliding rod 22 toward the sliding plate 26. After the sliding rod 22 moves a certain distance toward the sliding plate 26, the other end of the sliding rod 22 suddenly hits the sliding plate 26, and the other end of the sliding rod 22 is restored to the state of abutting against the sliding plate 26. After the rotating plate 37 moves with the sliding plate 26 to the other end of the sliding rod 22, the vertical plate 32 will also swing and reset under the elastic reset action of the two fourth coil springs 38.

[0078] With this structure, the pushing portion can push the sliding rod 22 when it moves with the sliding plate 26 and passes the other end of the sliding rod 22, so that the sliding rod 22 moves away from the sliding plate 26. In addition, when the pushing portion moves with the sliding plate 26 toward the vertical plate 32 and passes the other end of the sliding rod 22, and when the pushing portion moves with the sliding plate 26 away from the vertical plate 32 and passes the other end of the sliding rod 22, the pushing portion can push the sliding rod 22 away from the sliding plate 26.

[0079] After the sliding rod 22 moves a certain distance away from the sliding plate 26, the other end of the sliding rod 22 can be instantly separated from the rotating plate 37. After the other end of the sliding rod 22 is instantly separated from the rotating plate 37, the second coil spring 27 can be quickly reset, and the sliding rod 22 can quickly move toward the sliding plate 26 and pull the corn plant stem, so that the corn plant stem can quickly swing toward the sliding rod 22. After the sliding rod 22 moves a certain distance toward the sliding plate 26, the sliding rod 22 can quickly hit the sliding plate 26, and a large impact force can be formed between the sliding rod 22 and the sliding plate 26. The sliding rod 22 can provide a large impact force on the corn plant stem, making it easier to shake off the pollen on the corn flower, which can further increase the pollen concentration in the first bag body 1 and the second bag body 2, and can further improve the pollination effect.

[0080] In this embodiment, circular grooves are formed on the upper and lower side walls of the cavity 35, and the groove on the upper side wall of the cavity 35 is arranged opposite to the groove on the lower side wall of the cavity 35; the pushing portion also includes a rotating shaft 39, and the upper and lower ends of the rotating shaft 39 are respectively rotatably engaged in the two grooves, and the one end of the rotating plate 37 is fixedly connected to the rotating shaft 39. With this structure, the one end of the rotating plate 37 can be rotatably set in the cavity 35.

[0081] In some embodiments, the first air tube 7, the second air tube 8 and the third air tube can all be plastic corrugated hoses, which have a retractable structural feature, so that the first air tube 7, the second air tube 8 and the third air tube can all be retracted within a certain range, thereby enabling the distance between the first bag body 1 and the second bag body 2 to be adjusted. Since the distance between the tassel and the female ear of different corn varieties is different, when the pollination device for corn seed production described in the present invention is applied to different varieties of corn, the distance between the first bag body 1 and the second bag body 2 can be adjusted so that the distance between the first bag body 1 and the second bag body 2 can be adapted to the distance between the tassel and the female ear of different varieties of corn. With this structure, the applicable scope of the pollination device for corn seed production described in the present invention can be increased.
