[0031] The beneficial effects of this invention are as follows:

[0032] 1. In this invention, the lifting mechanism drives the lifting seat downwards. After the drill bit structure contacts the ground, it drills into the soil. The soil collection hood stores the drilled soil fragments. Once the drilling depth reaches the sowing requirement, the lifting and rotating mechanisms stop working, opening the through hole so that the seeds can pass through and enter the bottom of the borehole. The lifting seat moves to its highest position. During the upward movement of the lifting seat, the flipping mechanism rotates the baffle, allowing the fertilizer above the baffle to enter the drill cylinder and then through the through hole into the borehole. The soil fragments in the soil collection hood fall into the borehole, thus absorbing the fertilizer. Covering is performed automatically; this seeding device automatically completes drilling, sowing, fertilizing, and covering, improving the efficiency of the seeding device; fertilizer and seeds are separated by broken soil, avoiding direct contact between seeds and fertilizer and reducing the chance of seed damage; by adjusting the working position of the flipping mechanism, the distance between fertilizer and seeds can be adjusted to adapt to different seeds and fertilizers; when the drill cylinder moves downward, the sealing mechanism is in a sealing state, sealing the through hole to prevent broken soil from accumulating in the through hole, ensuring that seeds and fertilizer move smoothly through the through hole into the drill hole, improving the reliability of the seeding device.

[0033] 2. In this invention, when the lifting seat moves downward, it drives the sliding cylinder downward, which in turn drives the driving component downward, causing the picking part to move, and thus the seeds and fertilizer to move. When the picking part abuts against the second limiting structure, the picking part stops moving, causing the sliding cylinder and the conveying cylinder to form a sliding connection, keeping the sliding cylinder stationary. The conveying cylinder continues to move downward following the lifting seat. When the picking part stops moving, the seed picking trough moves to the outside of the square cylinder structure, and the seeds in the seed picking trough slide into the first inclined part, passing through the first vertical part, the sliding cylinder, and the conveying cylinder into the drill cylinder. Meanwhile, the fertilizer picking trough moves to the outside of the square cylinder structure, and the fertilizer in the fertilizer picking trough slides into the first inclined part, passing through the first vertical part, the sliding cylinder, and the conveying cylinder into the drill cylinder. The vertical section and sliding cylinder enter the conveying cylinder and accumulate above the baffle, automatically completing the seed and fertilizer extraction work. When the lifting seat moves upward, it drives the conveying cylinder to move upward. When the first driving component is aligned with the first limiting groove, the elastic force of the first elastic component causes the first driving component to abut against the first limiting groove, forming a fixed connection between the sliding cylinder and the conveying component. This drives the sliding cylinder to move upward, which in turn drives the driving component to move upward, thus moving the extraction part. When the lifting seat moves to the highest position and stops moving, the extraction part stops moving. At this time, the seed extraction trough is located on the upper side of the square cylinder structure, and the seeds enter the seed extraction trough. The fertilizer extraction trough is also located on the upper side of the square cylinder structure, and the fertilizer enters the seed extraction trough.

[0034] 3. In this invention, after the drill barrel drills to the set depth and stops rotating, the No. 4 motor works, driving the No. 4 connecting shaft to rotate in the forward direction, which in turn drives the connecting plate to move downward, and drives the blocking plate to move downward, so that the blocking plate leaves the lower opening of the through hole, opening the through hole and facilitating the downward movement of seeds or fertilizer through the through hole; before the lifting mechanism drives the lifting seat to move downward, it drives the No. 4 connecting shaft to rotate in the reverse direction, so that the blocking plate moves to a high position and abuts against the lower opening of the through hole, sealing the through hole.

[0035] 4. In this invention, during the downward movement of the sliding seat, when the No. 3 gear meshes with the No. 3 rack, the No. 3 gear rotates counterclockwise, causing the baffle to generate a counterclockwise rotational force. At this time, the limiting part abuts against the inner wall of the No. 3 inclined part, preventing the baffle from rotating counterclockwise. This causes the No. 3 limiting part to disengage from the No. 3 groove, forming a rotational connection between the No. 3 gear and the No. 3 connecting part. This prevents the fertilizer from slipping due to the rotation of the baffle when the sliding seat moves downward. During the upward movement of the sliding seat, when the No. 3 gear meshes with the No. 3 rack, the No. 3 gear rotates clockwise... The clockwise rotation causes the baffle to rotate clockwise, causing the fertilizer above the baffle to slide down and enter the drill barrel. When the third gear is not engaged with the third rack, the third elastic plate causes the limiting part at one end of the baffle to abut against the inner wall of the third inclined part, thus sealing the third inclined part. Rotating the third connecting shaft causes the sliding parts to slide, adjusting the meshing position of the third gear and the third rack, adjusting the distance between the drill bit structure and the bottom of the borehole when the baffle rotates, and adjusting the distance between the fertilizer and the seeds.

[0036] 5. In this invention, the upper surface of the blocking plate is inclined, which facilitates the sliding of seeds or fertilizers from the inclined surface and reduces the probability of seeds or fertilizers remaining on the upper surface of the blocking plate. Attached Figure Description

Detailed Implementation

[0058] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0059] like Figures 1-19 As shown, a seeding device for crop cultivation includes a frame 1, a drill cylinder 2, a sealing mechanism 3, and a picking mechanism 4;

[0060] A lifting seat 11 is vertically slidably connected to the frame 1; a drill barrel 2 is rotatably connected to the lifting seat 11; a through hole 21 is provided at the lower end of the drill barrel 2; a sealing mechanism 3 is used to seal the through hole 21.

[0061] A container 12 is symmetrically arranged on the frame 1; the container 12 is fixedly connected to the frame 1; a conveyor cylinder 13 is arranged below the container 12; the conveyor cylinder 13 is fixedly connected to the lifting seat 11; the conveyor cylinder 13 and the container 12 are connected by a picking mechanism 4; one picking mechanism 4 is used to pick up seeds; the other picking mechanism 4 is used to pick up fertilizer; a baffle 14 rotates inside one of the conveyor cylinders 13.

[0062] A sliding seat 15 is slidably connected to the lifting seat 11; a soil collection cover 16 is fixed to the lower end of the sliding seat 15.

[0063] The seeding device also includes a flipping mechanism 5, a lifting mechanism 6, a rotating mechanism 7, and a traveling mechanism 8; the flipping mechanism 5 is used to drive the baffle 14 to rotate; the lifting mechanism 6 is used to drive the lifting seat 11 to slide; the rotating mechanism 7 is used to drive the drill barrel 2 to rotate; and the traveling mechanism 8 is used to drive the frame 1 to move.

[0064] During operation, the user activates the walking mechanism 8 via the controller. The walking mechanism 8 moves the frame 1, moving the sowing device to the sowing position (one holding box 12 holds seeds, with a picking mechanism 4 below it for picking up seeds; another holding box 12 holds fertilizer, with a picking mechanism 4 below it for picking up fertilizer, and a baffle 14 rotates inside the conveying cylinder 13 below it). The user then executes the sowing program via the controller. The controller first changes the working state of the sealing mechanism 3, placing it in a sealing state to seal the through hole 21. Then, the controller activates the lifting mechanism 6, which moves the lifting seat 11 downwards, bringing the drill cylinder 2, sliding seat 15, and soil collection cover 16 closer to the ground. After the lower end of the soil collection cover 16 touches the ground (before the soil collection cover 16 touches the ground, one picking mechanism 4 takes seeds from the holding box 12, so that the seeds pass through the conveying cylinder 13 and enter the drill cylinder 2, and finally enter the lower end of the drill bit; another picking mechanism 4 takes fertilizer from the holding box 12, so that the fertilizer enters the conveying cylinder 13 and accumulates above the baffle 14), the lifting seat 11 continues to move downward. At this time, the soil collection cover 16 remains stationary. While the lifting seat 11 continues to move downward, the controller makes the rotating mechanism 7 work. The rotating mechanism 7 drives the drill cylinder 2 to rotate, so that the drill cylinder 2 rotates while moving downward. After the drill bit structure 22 of the drill cylinder 2 (the lower end of the drill cylinder 2 is equipped with a drill bit structure 22) touches the ground, it drills into the soil. The soil collection cover 16... The drilled soil is stored. After the drilling depth of the drill bit structure 22 reaches the sowing requirement, the controller pauses the operation of the lifting mechanism 6 and the rotating mechanism 7. Then, the controller activates the sealing mechanism 3, changing its working state to a non-sealing state, opening the through hole 21 and allowing the seeds to enter the bottom of the borehole through the through hole 21. Subsequently, the controller activates the lifting mechanism 6, moving the lifting seat 11 to its highest position. As the lifting seat 11 moves upward, it drives the drill cylinder 2 upward, which in turn drives the drill bit structure 22 upward. As the drill bit structure 22 moves upward, soil falls downward to cover the seeds. During the upward movement of the lifting seat 11, the flipping mechanism 5 rotates the baffle 14, allowing the fertilizer above the baffle 14 to enter the drill cylinder 2. Inside, the drill bit structure 22 enters the borehole through the through hole 21. When the lifting seat 11 abuts against the first limiting structure 152 (the sliding seat 15 is evenly spaced with guide columns 151, and the upper end of the guide columns 151 is provided with the first limiting structure 152, and the guide columns 151 are slidably connected to the lifting seat 11), the drill bit structure 22 moves into the soil collection cover 16. After that, the lifting seat 11 drives the first limiting structure 152 to move upward, drives the guide columns 151 and the sliding seat 15 to move upward, and drives the soil collection cover 16 to move upward. The broken soil in the soil collection cover 16 falls into the borehole to cover the fertilizer. The drilling, sowing, fertilization and covering work of one sowing position is completed, and the sowing work of one position is completed. The above work is repeated to sow the next sowing position.

[0065] This sowing device automatically completes drilling, sowing, fertilizing, and covering, improving the efficiency of the sowing device. During the upward movement of the lifting seat 11, the flipping mechanism 5 rotates the baffle 14, allowing fertilizer on the baffle 14 to enter the hole. This separates the fertilizer and seeds from the soil, preventing direct contact, reducing seed damage, and increasing germination rate. By adjusting the working position of the flipping mechanism 5, the distance between the drill bit structure 22 and the bottom of the hole is adjusted when the baffle 14 rotates, thus adjusting the distance between the fertilizer and seeds to accommodate different seeds and fertilizers, improving the adaptability of the sowing device. When the drill cylinder 2 moves downward, the sealing mechanism 3 is in a sealing state, sealing the through hole 21 to prevent soil from accumulating inside the through hole 21 (or entering the drill cylinder 2 through the through hole 21), ensuring that seeds and fertilizer smoothly move through the through hole 21 into the hole, improving the reliability of the sowing device.

[0066] The picking mechanism 4 includes a picking component 41, a fixed cylinder 42, a sliding cylinder 43, a connecting cylinder 44, and a driving component 45;

[0067] The lower end of the container 12 is provided with a square tube structure 121; the taking part 41 includes a taking part 411 and a horizontal part 412; the horizontal part 412 is provided with a drive groove 4121; the taking part 411 is slidably connected inside the square tube structure 121;

[0068] The fixed cylinder 42 is fixedly connected to the container 12; the fixed cylinder 42 includes a first inclined part 421 and a first vertical part 422.

[0069] A sliding cylinder 43 is slidably connected inside the conveying cylinder 13; a limiting groove is provided on the upper side wall of the sliding cylinder 43; a connecting cylinder 44 is fixedly connected to the outer wall of the upper end of the conveying cylinder 13; a sliding column 46 is slidably connected inside the connecting cylinder 44; a limiting element 47 is provided at one end of the sliding column 46; an elastic element 48 is provided at the other end of the sliding column 46; the elastic element 48 is used to provide elastic support for the sliding column 46.

[0070] A drive component 45 is connected to the sliding cylinder 43; the drive component 45 abuts against the drive groove 4121; a first vertical part 422 is slidably connected inside the sliding cylinder 43.

[0071] One picking part 411 is provided with seed picking grooves 4131 evenly spaced; the other picking part 411 is provided with fertilizer picking grooves 4141.

[0072] When the lifting seat 11 moves downward, it drives the conveying cylinder 13 to move downward, which in turn drives the sliding cylinder 43 to move downward (at this time, the elastic force of the first elastic element 48 causes the first limiting element 47 to abut against the first limiting groove, and the sliding cylinder 43 and the conveying cylinder 13 form a fixed connection). This drives the driving element 45 to move downward, and the driving element 45 exerts a downward force on the side wall of the driving groove 4121 and a downward force on the horizontal part 412, driving the picking part 411 to move (before the picking part 411 moves, the seed picking groove 4131 is located on the upper side of the square cylinder structure 121, and the seeds enter the seed picking groove 4131, and the fertilizer picking groove 4141 is located on the upper side of the square cylinder structure 121, and the fertilizer enters the seed picking groove 4131). This drives the seeds and fertilizer to move. When the picking part 411 abuts against the second limiting structure 4211 (the second limiting structure 4211 is provided on the first inclined part 421), the seeds and fertilizer are picked up. When part 411 stops moving, the conveying cylinder 13 continues to move downward, resisting the elastic force of the first elastic element 48, causing the first limiting element 47 to disengage from the first limiting groove, so that the sliding cylinder 43 and the conveying cylinder 13 form a sliding connection, keeping the sliding cylinder 43 stationary, and the conveying cylinder 13 continues to move downward with the lifting seat 11. When the picking part 411 stops moving, the seed picking trough 4131 moves to the outside of the square cylinder structure 121, and the seeds in the seed picking trough 4131 slide into the first inclined part 421, pass through the first vertical part 422, the sliding cylinder 43, and the conveying cylinder 13 and enter the drill cylinder 2. At the same time, the fertilizer picking trough 4141 moves to the outside of the square cylinder structure 121, and the fertilizer in the fertilizer picking trough 4141 slides into the first inclined part 421, pass through the first vertical part 422 and the sliding cylinder 43 and enter the conveying cylinder 13, and accumulate above the baffle 14, automatically completing the seed picking and fertilizer picking work.

[0073] When drilling is completed and the lifting seat 11 moves upward, it drives the conveying cylinder 13 to move upward, which in turn drives the first driving component 45 to move upward. When the first driving component 45 is directly opposite the first limiting groove, the elastic force of the first elastic component 48 causes the first driving component 45 to abut against the first limiting groove, so that the sliding cylinder 43 and the conveying component form a fixed connection, driving the sliding cylinder 43 to move upward, which in turn drives the driving component 45 to move upward. The driving component 45 generates an upward force on the horizontal part 412, which drives the picking part 411 to move. When the lifting seat 11 moves to the highest position and stops moving, the picking part 411 stops moving. At this time, the seed picking trough 4131 is located on the upper side of the square cylinder structure 121, and the seeds enter the seed picking trough 4131. The fertilizer picking trough 4141 is located on the upper side of the square cylinder structure 121, and the fertilizer enters the seed picking trough 4131.

[0074] The blocking mechanism 3 includes a blocking plate 31, a connecting plate 32, a connecting rod 33, a fourth connecting shaft 34, a fourth motor 35, and a fourth transmission component 36;

[0075] A blocking plate 31 is provided at the lower end of the drill barrel 2; a connecting plate 32 is provided above the blocking plate 31; a connecting rod 33 is provided between the connecting plate 32 and the blocking plate 31; connecting rods 33 are symmetrically provided at both ends of the connecting plate 32; the lower end of the connecting rod 33 is fixedly connected to the blocking plate 31; the upper end of the connecting rod 33 is fixedly connected to the connecting plate 32; the connecting rod 33 is slidably connected to the side wall of the drill barrel 2.

[0076] The upper end of the drill barrel 2 is rotatably connected to the fourth connecting shaft 34; the connecting plate 32 is threadedly connected to the fourth connecting shaft 34; the upper end of the drill barrel 2 is fixedly connected to the fourth motor 35; the fourth connecting shaft 34 and the rotating shaft of the fourth motor 35 are driven by the fourth transmission component 36.

[0077] After the drill barrel 2 drills to the set depth and stops rotating, the controller activates motor 35, which drives the fourth connecting shaft 34 to rotate forward via transmission component 36. This causes the connecting plate 32 to move downward, and the connecting rod 33 to move the blocking plate 31 downward, bringing it to its lowest position. This allows the blocking plate 31 to leave the lower opening of the through hole 21, opening the through hole 21 and facilitating the downward movement of seeds or fertilizer through it. Before the lifting mechanism 6 moves the lifting seat 11 downward, the controller activates motor 35, which drives the fourth connecting shaft 34 to rotate in the opposite direction via transmission component 36. This causes the connecting plate 32 to move upward, and the connecting rod 33 to move the blocking plate 31 upward, bringing it to its highest position. This allows the blocking plate 31 to abut against the lower opening of the through hole 21, sealing it.

[0078] The conveying cylinder 13 includes a third vertical section 131 and a third inclined section 132; a sliding cylinder 43 is slidably connected inside the third vertical section 131; and a baffle 14 is rotatably connected inside one of the third inclined sections 132.

[0079] The flipping mechanism 5 includes a third rotating shaft 51, a third gear 52, a sliding member 53, a third rack 54, a third connecting shaft 55, and a third elastic plate 56;

[0080] One end of the baffle 14 is fixed with the third rotating shaft 51; the other end of the baffle 14 is provided with a limiting part 141; the third rotating shaft 51 is rotatably connected to the third inclined part 132; the third gear 52 is rotatably connected to the third rotating shaft 51; the third groove 521 is evenly spaced on the side of the third gear 52.

[0081] The third rotating shaft 51 is provided with a third connecting part 511; the third connecting part 511 is provided with a third mounting groove 5111; a third sliding column 57 is slidably connected in the third mounting groove 5111; one end of the third sliding column 57 is connected to a third limiting member 58; the third limiting member 58 abuts against one of the third grooves 521; the other end of the third sliding column 57 is connected to a third elastic member 59; the third elastic member 59 is used to provide elastic support for the third sliding column 57.

[0082] A sliding member 53 is slidably connected to the frame 1; a third rack 54 is fixed on the sliding member 53; a third connecting shaft 55 is rotatably connected to the frame 1; the third connecting shaft 55 is threadedly connected to the sliding member 53; one end of the third elastic plate 56 is fixedly connected to the baffle 14; the other end of the third elastic plate 56 abuts against the inner wall of the third inclined part 132.

[0083] During the downward movement of the sliding seat 15, when the third gear 52 meshes with the third rack 54, the third gear 52 rotates counterclockwise. The inner wall of the third groove 521 exerts a force on the third limiting member 58 (at this time, the elastic force of the third elastic member 59 causes the third limiting member 58 to abut against a third groove 521). This causes the third limiting member 58 to rotate with the third gear 52, causing the third connecting part 511 to rotate counterclockwise, causing the third rotating shaft 51 to rotate counterclockwise, and causing the baffle 14 to rotate counterclockwise. At this time, the limiting part... 141 abuts against the inner wall of the third inclined part 132, the baffle 14 cannot rotate counterclockwise, resists the elastic force of the third elastic member 59, and causes the third limiting member 58 to disengage from the third groove 521, so that the third gear 52 and the third connecting part 511 form a rotational connection. While the third gear 52 rotates counterclockwise, the baffle 14 remains stationary, and prevents the fertilizer from slipping when the sliding seat 15 moves downward. When the third gear 52 and the third rack 54 separate, the elastic force of the third elastic member 59 causes the third limiting member 58 to abut against a third groove 521 again.

[0084] During the upward movement of the sliding seat 15, when the third gear 52 meshes with the third rack 54, the third gear 52 rotates clockwise. The inner wall of the third groove 521 exerts a force on the third limiting member 58, causing the third limiting member 58 to rotate with the third gear 52. This causes the third connecting part 511 to rotate clockwise, the third rotating shaft 51 to rotate clockwise, and the baffle 14 to rotate clockwise. This resists the force of the third elastic plate 56, causing the baffle 14 to rotate clockwise, and the fertilizer above the baffle 14 to slide down and enter the drill barrel 2.

[0085] When gear 52 is not engaged with rack 54, elastic plate 56 causes the limiting part 141 at one end of baffle 14 to abut against the inner wall of inclined part 132, and baffle 14 blocks inclined part 132 to prevent fertilizer from slipping.

[0086] Rotating the third connecting shaft 55 causes the sliding part 53 to slide, which in turn causes the third rack 54 to move. Adjusting the meshing position of the third gear 52 and the third rack 54, adjusting the distance between the drill bit structure 22 and the bottom of the drill hole when the baffle 14 rotates, and adjusting the distance between the fertilizer and the seed can adapt to different seeds and fertilizers, thereby improving the adaptability of the sowing device.

[0087] The upper surface of the blocking plate 31 is inclined; the lower end of the drill barrel 2 is provided with a relief groove; the upper bottom surface of the relief groove is inclined.

[0088] The upper surface of the blocking plate 31 is inclined, which makes it easier for seeds or fertilizers to slide off the inclined surface and reduces the chance of seeds or fertilizers being stuck on the upper surface of the blocking plate 31. After the blocking plate 31 is moved to the highest position, the upper surface of the blocking plate 31 abuts against the upper bottom surface of the relief groove to block the through hole 21.

[0091] Replace the fixing piece 413 with the corresponding seed-collecting groove 4131 according to the size of the seed particles to meet the seed-collecting work of different sizes of seeds and improve the adaptability of the seed-collecting piece; install the corresponding number of fixing pieces 413 according to the number of seeds in each drill hole, and replace the excess fixing pieces 413 with fixing posts without seed-collecting grooves 4131 to meet different sowing requirements and improve the adaptability of the seed-collecting piece; rotate the threaded shaft 416 according to the amount of fertilizer required, drive the sliding plate 415 to move, change the position of the sliding plate 415, change the effective volume of the fertilizer-collecting groove 4141, change the fertilizer volume, and improve the applicability of the fertilizer-collecting piece.

The driving component 45 can roll on the side wall of the driving groove 4121, reducing the friction between the driving component 45 and the side wall of the driving groove 4121. The first limiting component 47 is spherical and can roll on the outer wall of the sliding cylinder 43, reducing the friction between the first limiting component 47 and the outer wall of the sliding cylinder 43. The third limiting component 58 is spherical and can rotate, reducing the friction between the third limiting component 58 and the inner wall of the third groove 521.
