[0070] Now, reference will be made in detail to the implementation modes, examples of which are shown in the accompanying drawings. Many specific details are set forth in the following detailed description in order to provide a thorough understanding of the various described implementation modes. However, it will be apparent to those of ordinary skill in the art that the various described implementation modes may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the implementation modes.

[0071] This embodiment discloses a seeding device. The seeding device implements at least steps such as seed collection and seeding in an automated seeding operation; before the seed collection step, the height of the seed storage container is adjusted according to the quantity and / or stacking height of the seeds to avoid the possibility of failed seed collection or insufficient quantity.

[0072] Figure 1 The structural schematic diagram of the seeding device of this embodiment is shown. Figure 1 It is shown that the seeding device of this embodiment includes a mobile platform, a seed bin 30, a lifting mechanism 40, a transfer mechanism 50, and a controller.

[0073] Among them, the mobile platform is composed of a square platform 10 and a driving mechanism 20. The mobile platform moves along one or more horizontal directions according to an automated instruction or a manual instruction.

[0074] Moreover, a seed bin 30, a lifting mechanism 40, a transfer mechanism 50, and a controller (not shown in the figure) are respectively installed on the square platform 10. The seed bin 30 serves as a container for storing seeds. The controller drives the lifting mechanism 40 to lift or lower the seed bin 30 according to the quantity and / or stacking height of the seeds in the seed bin 30, so as to maintain the stacking height of the seeds in the seed bin 30 relative to the square platform 10. When the stacking height of the seeds in the seed bin 30 is maintained, the controller drives the transfer mechanism 50 to collect one or more seeds at the upper part of the stacked seeds and transfer them to the outside or bottom of the external square platform 10 to complete seed sowing.

[0075] Therefore, in the first aspect of the sowing device of this embodiment, the transfer mechanism 50 follows the moving route of the mobile platform to perform seed taking operations and sowing operations; in the second aspect, the lifting mechanism 40 lifts the entire seed bin 30 according to the quantity and / or stacking height of the seeds before the seed taking operation, improving the success rate and efficiency of the seed taking operation.

[0076] Figure 2 The structural schematic diagram of the driving mechanism of this embodiment is shown. Figure 2 The driving mechanism of this embodiment is shown to include two driving components and two universal wheels 28. The two driving components and the two universal wheels 28 are deployed at the four corners of the square platform 10. The two driving components serve as the front drive of the square platform 10.

[0077] Among them, each driving component includes a motor bracket 21, a driving motor 22, a motor sprocket 23, a tire sprocket 24, a connecting flange 26, and a driving tire 27. The motor bracket 21 is installed on the upper surface of the square platform 10, and the connecting flange 26 is installed on the lower surface of the square platform 10. The driving motor 22 is installed on the lower surface of the motor bracket 21, and the driving tire 27 is rotatably connected to the connecting flange 26 through a bearing. The motor sprocket 23 is connected to the drive shaft of the driving tire 27 and the motor shaft of the driving motor 22 through a transmission chain 25 by a sprocket hole opened in the square platform 10, realizing the synchronous rotation of the driving motor 22 and the driving tire 27. The driving motor 22 is driven by the controller.

[0078] Therefore, the two driving components of the driving mechanism 20 of this embodiment can drive the mobile platform to move linearly in the horizontal direction or turn the mobile platform by using the speed difference between the driving motors 22 on both sides, realizing the flexible movement of the sowing device of this embodiment.

[0079] Figure 3 The structural schematic diagram of the seed bin and the lifting mechanism of this embodiment installed on the mobile platform is shown. Figure 4 The part schematic diagram of the lifting mechanism of this embodiment is shown.

[0080] Figure 3It is shown that the seed bin includes a bin support 31 and four storage bins 32. The storage bins 32 are containers with openings facing upward, and the four storage bins 32 are installed on the bin support 31 at intervals along the length direction. Two lifting mechanisms 40 are respectively installed on both sides of the bin support 31 and synchronously drive the lifting or lowering of the bin support 31.

[0081] Figure 4 It is shown that the lifting mechanism includes a fixing plate, a rotating pin shaft 42, an electric lifting rod 43, and a pressure sensor 44. The fixing plate is composed of a vertical side plate 411 and a horizontal side plate 412 and has an L-shaped cross-section. The vertical side plate 411 is installed on the corresponding side of the bin support 31 in the vertical direction. A rotating seat 4121 is formed at the bottom of the horizontal side plate 412, and the rotating seat 4121 is configured with a first pin hole. A second pin hole is formed at the rod end of the electric lifting rod 43. The rotating pin shaft 42 is respectively in rotational fit with the first pin hole and the second pin hole. A rotating gap is formed between the horizontal side plate 412 and the rod end of the electric lifting rod 43, and the rotating gap restricts the relative angle of the rotating pin shaft 42 relative to the rod end of the electric lifting rod 43. The pressure sensor 44 is installed in the rotating gap and is connected to the controller. The base of the electric lifting rod 43 is installed on the square platform 10 in the vertical direction and is connected to the controller.

[0082] Therefore, in this embodiment, the seed bin 30 cooperates with the two lifting mechanisms 40 to solve the problems that during the sowing operation, as the number of seeds decreases, the stacking height of the seeds in the four storage bins 32 decreases, resulting in the transfer mechanism 50 being unable to contact the seeds at a suitable height when taking seeds. Specifically, according to the weight of the seeds in the seed bin 30, a rotational tendency is generated for the lever of the fixing plate relative to the electric lifting rod 43. The rotational tendency causes the fixing plate to press the pressure sensor 44. The pressure sensor 44 generates a pressure signal according to the pressure. The controller judges the average weight of the seeds in the four storage bins 32 based on the pressure signals of the two pressure sensors 44 and analyzes to obtain the average stacking height of the seeds in the four storage bins 32. The controller transmits a lifting signal to the electric lifting rod 43 according to the average stacking height of the seeds in the four storage bins 32. The two electric lifting rods 43 synchronously lift or lower the bin support 31 according to the lifting signal, so that the stacking height of the seeds in the four storage bins 32 remains within a threshold range relative to the moving platform, ensuring the success rate and quantity of the seed-taking operation of the transfer mechanism 50 in the storage bin 32 before the seed-taking operation.

[0083] In this embodiment, the analysis of the stacking height of the seeds in the storage bin 32 by the controller can be directly obtained by querying the weight and stacking height comparison table. The weight and stacking height are established according to the internal shape of the storage bin 32, the seed weight, the collision volume of the seeds, etc.

[0084] Preferably, when the pressure signals of the two pressure sensors 44 are inconsistent or exceed a threshold difference, it indicates that the stacking heights of the seeds in the four storage bins 32 are different. At this time, the controller will send an alarm signal to the outside or control the sound device and / or light device that can be installed on the mobile platform to implement the alarm.

[0085] Preferably, the angle of the lateral side plate 412 relative to the rod end of the electric lifting rod 43 is less than 15°. Then the lateral side plate 412 can only rotate limitedly relative to the electric lifting rod 43, avoiding excessive tilting of the storage bin 32 and causing the seeds in the storage bin 32 to fall out.

[0086] In some embodiments, the seed bin 30 of this embodiment can be lifted by a lifting mechanism 40.

[0087] Figure 5 The structural schematic diagram of the transfer mechanism of this embodiment is shown. Figure 5 The transfer mechanism is shown to include four funnels 51, four seed collection components 52 and a transfer component 60. The four funnels 51 and the four seed collection components 52 correspond to the four storage bins 32 respectively.

[0088] Among them, the four funnels 51 are installed on the square platform 10 at the same interval as the four storage bins 32. The large end of each funnel 51 faces vertically upward, and the small end penetrates through the bottom of the square platform 10. The seed collection component 52 sucks or places the seeds in the storage bin 32 by adsorption. The transfer mechanism 50 reciprocally transfers the seed collection component 52 between the funnel 51 and the corresponding storage bin 32. When adsorbing seeds, the transfer mechanism 50 transfers the seed collection component 52 to a threshold height extending into the storage bin 32, and the seed collection component 52 completes the adsorption of the seeds in the storage bin 32 at this threshold height. The transfer mechanism 50 and the seed collection component 52 are driven by the controller.

[0089] In this embodiment, the transfer of the four seed collection components 52 by the transfer mechanism 50 is synchronous, and the adsorption of the seeds in their respective storage bins 32 by the four seed collection components 52 is synchronous.

[0090] Therefore, in the first aspect, the controller of this embodiment drives the transfer mechanism 50 to synchronously transfer the four seed collection components 52 to the threshold height in their respective storage bins 32. In the second aspect, it drives the four seed collection components 52 to adsorb seeds in their respective storage bins 32. In the third aspect, it drives the transfer mechanism 50 to synchronously transfer the four seed collection components 52 with adsorbed seeds above their respective funnels 51. In the fourth aspect, it drives the four seed collection components 52 to release the adsorption of the seeds respectively, so that the seeds naturally fall to the ground through the funnels 51.

[0091] Figure 6 The part schematic diagram of the transfer component 60 of this embodiment is shown. Figure 6It is shown that the transfer assembly 60 includes a base 61, a rocker support 621, an intermediate support 622, a transfer motor 63, a first connecting rod 641, a second connecting rod 642, a third connecting rod 643, and a connecting plate 644.

[0092] Among them, the base is installed on the mobile platform. The rocker support 621 and the intermediate support 622 are respectively installed on the base. The transfer motor 63 is installed on the rocker support 621. In the same vertical rotation plane, one end of the first connecting rod 641 is fixedly connected to the motor shaft of the transfer motor 63, and the other end is rotatably connected to one end of the second connecting rod 642; the other end of the second connecting rod 642 relative to the first connecting rod 641 is rotatably connected to the connecting plate 644 and the third connecting rod 643 coaxially, and the other end of the third connecting rod 643 relative to the second connecting rod 642 is rotatably connected to the intermediate support 622; four seed collection assemblies 52 are installed on the connecting plate 644 at intervals. The transfer motor 63 is driven by a controller.

[0093] Then, the first connecting rod 641, the second connecting rod 642 and the third connecting rod 643 form a hinge four-bar transmission member with one crank and one rocker. The active rotation fulcrum of the hinge four-bar transmission member is the motor shaft of the transfer motor 63, and the passive rocker fulcrum is the rotation node between the intermediate support 622 and the third connecting rod 643.

[0094] Therefore, in this embodiment, the controller drives the transfer motor 63, and the transfer motor 63 drives the hinge four-bar transmission member, so that the connecting plate 644 swings following the swing node between the second connecting rod 642 and the third connecting rod 643. During the swinging process of the connecting plate 644, the seed collection assemblies 52 approach or move away from their respective storage bins 32 and funnels 51 repeatedly.

[0095] Preferably, the controller controls the rotation speed of the transfer motor 63. On the one hand, it can realize the control of the sowing spacing. Controlling the rotation speed of the transfer motor 63 will cooperate with

[0096] Preferably, Figure 6 It is shown that the transfer assembly includes a limit assembly. The limit assembly includes a slider 65, a support 623, a limit rod 66 and a slider 65. The slider 65 support 623 is installed on the base. The slider 65 support 623 is rotatably connected to the slider 65. The connecting plate 644 is fixedly connected to one end of the limit rod 66, and the slider 65 is slidably connected to the limit rod 66.

[0097] Therefore, in this embodiment, during the swinging process of the connecting plate 644, the limit assembly restricts the swinging of the connecting plate 644 and maintains the stability of the connecting plate 644 during the swinging process.

[0098] Figure 6It is shown that the seed collection assembly 52 includes four suction pipes 521 and corresponding four air pumps 53. The four suction pipes 521 are installed on the connecting plate 644 at intervals, and the four pairs of air pumps 53 are installed on the square platform 10. Each air pump 53 is respectively connected to its respective air pump 53 through a hose (not shown in the figure). The other end of each suction pipe 521 relative to the hose is connected with a suction head 5211, and the suction head 5211 is used to hold the seeds for seed collection in an adsorption manner. The air pump 53 and its solenoid valve (not drawn in the figure) are driven by the controller.

[0099] Preferably, the suction head 5211 is detachably sleeved on the end of the suction pipe 521. The suction head 5211 is replaced according to the number of seeds sown each time to ensure the accurate number of seeds sown each time. Generally, the number of seeds sucked by each suction head 5211 from its respective storage bin 32 each time is between 3 and 5.

[0100] Therefore, in this embodiment, the controller drives the four air pumps 53. On the one hand, it makes the air pumps 53 work to generate negative pressure suction, and the suction head 5211 adsorbs the seeds in the storage bin 32 through the negative pressure suction; on the other hand, it makes the air pumps 53 stop working to relieve the negative pressure suction, and the suction head 5211 releases the adsorption of the seeds above the funnel 51, and the seeds fall into the funnel 51 under the action of gravity.

[0101] In summary, the sowing device in this embodiment realizes automatic walking through the mobile platform, and realizes automatic and accurate seed collection and sowing operations during walking through the seed bin, the transfer mechanism and the lifting mechanism.

[0102] Furthermore, the sowing device in this embodiment includes a slotting and soil covering mechanism 70.

[0103] Figure 7 The structural schematic diagram of the slotting and soil covering mechanism in this embodiment is shown. Figure 7 It is shown that the slotting and soil covering mechanism 70 includes a lower bracket 71 and four slotting and soil covering components. The lower bracket 71 is installed at the bottom of the square platform 10, and the four slotting and soil covering components are installed on the lower bracket 71 at intervals and respectively correspond to the four funnels 51.

[0104] Among them, the slotting and soil covering component includes a falling pipe 72, a connecting cross bar 73, a slotting square iron sheet 74 and a soil covering square iron sheet 75. The falling pipe 72 is vertically connected to the lower bracket 71, and the upper end of the falling pipe 72 is communicated with the small end of the corresponding funnel 51 through a hose. The bottom of the falling pipe 72 is connected to and penetrates through the connecting cross bar 73, and the connecting cross bar 73 is respectively installed with a slotting square iron sheet 74 and a soil covering square iron sheet 75 at both ends of the falling pipe 72. The connection line of the slotting square iron sheet 74, the falling pipe 72 and the soil covering square iron sheet 75 is parallel to the moving direction of the mobile platform, and the installation position of the slotting square iron sheet 74 relative to the soil covering square iron sheet 75 on the connecting cross bar 73 is closer to the front of the moving direction.

[0105] Preferably, the grooved square iron sheet 74 is configured as a sharp cone structure, and the covered soil square iron sheet 75 is configured as a U-shaped structure.

[0106] In this embodiment, Figure 8 The schematic diagram of the parts of the grooving and soil covering assembly is shown. Figure 8 It is shown that the grooving and soil covering assembly further includes a horse riding clamp 76 and a wing nut 77. The lower bracket 71 is provided with a moving groove in the horizontal direction. The horse riding clamp 76 holds the downcomer 72 tightly, and the wing nut 77 passes through the moving groove to lock the horse riding clamp 76.

[0107] Therefore, by adjusting the wing nut 77 and the horse riding clamp 76, the horizontal movement of the downcomer 72 can be realized, and further the seeding distance between two adjacent sown seeds can be changed.

[0108] Furthermore, the seeding device of this embodiment includes a seed ejecting mechanism 80.

[0109] Figure 9 The structural schematic diagram of the seed ejecting mechanism of this embodiment is shown. Figure 9 It is shown that the seed ejecting mechanism 80 includes two seed ejecting components. The two seed ejecting components are installed on the moving platform at intervals.

[0110] Among them, the seed ejecting component includes an electromagnetic telescopic rod 81. The base of the electromagnetic telescopic rod 81 is installed on the moving platform. The rod end of the electromagnetic telescopic rod 81 faces the bin support 31.

[0111] Therefore, the electromagnetic telescopic rod 81 can strike the bin support 31 multiple times, causing the storage bin 32 to vibrate, and further causing the seeds to bounce up, which is beneficial for the seed collection component 52 to collect the seeds.

[0112] In summary, the seeding device of this embodiment can adjust the adjacent seeding distance through the grooving and soil covering mechanism; through the oscillation generated by the seed ejecting mechanism for the seeds, the seed taking success rate is improved.

[0113] Therefore, the seeding device of this embodiment is an automated agricultural seeding machine, which can realize the seeding operation of controlling the adjacent seeding distance and the unit seeding cycle while automatically walking, and maintain the height of the stacked seeds during the seeding operation, effectively improving the seeding quantity and success rate, and achieving the technical purpose of automated precision seeding.
