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

[0032] 1. In the present invention, the lifting mechanism drives the lifting seat to move downward, and the drill bit structure drills the soil after contacting the ground. The soil collecting cover stores the drilled broken soil. After the drilling depth of the drill bit structure reaches the sowing requirement, the lifting mechanism and the rotating mechanism stop working, so that the through hole is opened, and the seed enters the bottom of the drill hole through the through hole, and the lifting seat moves to the highest position. During the upward movement of the lifting seat, the flip mechanism rotates the baffle, so that the fertilizer above the baffle enters the drill barrel and enters the drill hole through the through hole. The broken soil in the soil collecting cover falls into the drill hole, which improves the fertilizer. Covering; the sowing device automatically completes the drilling, sowing, fertilizing and covering work, thereby improving the efficiency of the sowing device; the fertilizer and seeds are separated by crushed soil, thereby avoiding direct contact between the seeds and fertilizer, and reducing the chance of seed damage; by adjusting the working position of the flip mechanism, the distance between the fertilizer and the seeds is adjusted to adapt to different seeds and fertilizers; when the drill tube moves downward, the blocking mechanism is in a blocking state, blocking the through hole, preventing crushed soil from accumulating in the through hole, ensuring that the seeds and fertilizer move smoothly through the through hole into the drill hole, and improving the reliability of the sowing device.

[0033] 2. In the present invention, when the lifting seat moves downward, the sliding cylinder is driven to move downward, the driving member is driven to move downward, the picking part is driven to move, and the seeds and fertilizer are driven to move. When the picking part contacts the No. 2 limiting structure, the picking part stops moving, so that the sliding cylinder and the conveying cylinder form a sliding connection, so that the sliding cylinder remains stationary, and the conveying cylinder continues to move downward with the lifting seat. When the picking part stops moving, the seed taking trough moves to the outside of the square cylinder structure, and the seeds in the seed taking trough slide into the No. 1 inclined part, pass through the No. 1 vertical part, the sliding cylinder, and the conveying cylinder into the drilling cylinder, and the fertilizer taking trough moves to the outside of the square cylinder structure, and the fertilizer in the fertilizer taking trough slides into the No. 1 inclined part, passes through the No. 1 vertical part, the sliding cylinder, and the conveying cylinder. When the lifting seat moves to the highest position and stops moving, the picking part stops moving. At this time, the seed taking groove is located on the upper side of the square tube structure, and the seeds enter the seed taking groove, and the fertilizer taking groove is located on the upper side of the square tube structure, and the fertilizer enters the seed taking groove.

[0034] 3. In the present invention, after the drill barrel drills to the set depth and stops rotating, the No. 4 motor starts to work, driving the No. 4 connecting shaft to rotate forward, driving the connecting plate to move downward, driving the blocking plate to move downward, so that the blocking plate moves away from the lower opening of the through hole, so that the through hole is open, and it is convenient for seeds or fertilizers to move downward from 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 opposite direction, so that the blocking plate moves to a high position, so that the blocking plate contacts the lower opening of the through hole, and blocks the through hole.

[0035] 4. In the present invention, when the sliding seat moves downward, when the No. 3 gear is engaged with the No. 3 rack, the No. 3 gear rotates counterclockwise, causing the baffle to generate a force to rotate counterclockwise. At this time, the limiting part abuts against the inner wall of the No. 3 inclined part, and the baffle cannot rotate counterclockwise, so that the No. 3 limiting part disengages from the No. 3 groove, so that the No. 3 gear and the No. 3 connecting part form a rotational connection, preventing the baffle from rotating and causing the fertilizer to slide when the sliding seat moves downward; when the sliding seat moves upward, when the No. 3 gear is engaged with the No. 3 rack, the No. 3 gear rotates clockwise. The clockwise rotation causes the baffle to generate a clockwise rotation force, causing the baffle to rotate clockwise, causing the fertilizer above the baffle to slide downward, and the fertilizer to enter the drill tube; when the No. 3 gear is not engaged with the No. 3 rack, the No. 3 elastic plate causes the limit part at one end of the baffle to contact the inner wall of the No. 3 inclined part, and the baffle blocks the No. 3 inclined part; rotating the No. 3 connecting shaft drives the sliding part to slide, adjusts the meshing position of the No. 3 gear and the No. 3 rack, adjusts the distance between the drill bit structure and the bottom of the drill hole when the baffle rotates, and adjusts the distance between the fertilizer and the seed.

[0036] 5. The upper end surface of the blocking plate in the present invention is an inclined surface, which facilitates the seeds or fertilizers to slide down the inclined surface and reduces the probability of the seeds or fertilizers being retained on the upper end surface of the blocking plate.

DETAILED DESCRIPTION

[0058] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0059] like Figures 1-19 As shown, a sowing device for planting crops includes a frame 1, a drill tube 2, a blocking mechanism 3 and a taking mechanism 4;

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

[0061] A holding box 12 is symmetrically provided on the frame 1; the holding box 12 is fixedly connected to the frame 1; a conveying cylinder 13 is provided below the holding box 12; the conveying cylinder 13 is fixedly connected to the lifting seat 11; the conveying cylinder 13 and the holding box 12 are connected via 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 conveying cylinder 13;

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

[0063] The sowing device also includes a turning mechanism 5, a lifting mechanism 6, a rotating mechanism 7 and a walking mechanism 8; the turning 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 tube 2 to rotate; and the walking mechanism 8 is used to drive the frame 1 to move.

[0064] During operation, the user operates the walking mechanism 8 through the controller, and the walking mechanism 8 drives the frame 1 to move, so that the sowing device moves to the sowing position (one holding box 12 is used to hold seeds, and the taking mechanism 4 below it is used to take seeds, and the other holding box 12 is used to hold fertilizers, and the taking mechanism 4 below it is used to take fertilizers, and a baffle 14 rotates in the conveying cylinder 13 below it). Then the user enables the controller to execute the sowing program. The controller first changes the working state of the blocking mechanism 3, so that the blocking mechanism 3 is in a blocking state, and blocks the through hole 21. Then the controller enables the lifting mechanism 6 to operate, and the lifting mechanism 6 drives the lifting seat 11 to move downward, so that the drill tube 2, the sliding seat 15 and the soil collecting cover 16 are close to the ground, and the soil collecting cover 16 After the lower end of the soil collecting cover 16 contacts the ground (before the soil collecting cover 16 contacts the ground, a taking mechanism 4 takes seeds from the holding box 12, so that the seeds pass through the conveying cylinder 13 into the drill barrel 2 and finally enter the lower end of the drill bit, and another taking 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 collecting cover 16 remains stationary. While the lifting seat 11 continues to move downward, the controller makes the rotating mechanism 7 work, and the rotating mechanism 7 drives the drill barrel 2 to rotate, so that the drill barrel 2 rotates while moving downward. The drill bit structure 22 of the drill barrel 2 (the lower end of the drill barrel 2 is provided with a drill bit structure 22) contacts the ground and drills the soil. The soil collecting cover 16 The drilled soil is stored. After the drilling depth of the drill bit structure 22 reaches the sowing requirement, the controller suspends the operation of the lifting mechanism 6 and the rotating mechanism 7. Then the controller activates the blocking mechanism 3 to change the working state of the blocking mechanism 3 to a non-blocking state, so that the through hole 21 is opened, and the seeds pass through the through hole 21 and enter the bottom of the drill hole. Then the controller activates the lifting mechanism 6 to move the lifting seat 11 to the highest position. When the lifting seat 11 moves upward, it drives the drill barrel 2 to move upward, and drives the drill bit structure 22 to move upward. When the drill bit structure 22 moves upward, the soil falls downward to cover the seeds. During the upward movement of the lifting seat 11, the flipping mechanism 5 rotates the baffle 14, so that the fertilizer above the baffle 14 enters the drill barrel 2. When the lifting seat 11 contacts the No. 1 limiting structure 152 (the sliding seat 15 is evenly spaced with guide posts 151, and the upper end of the guide posts 151 is provided with a No. 1 limiting structure 152, and the guide posts 151 are slidably connected to the lifting seat 11), the drill bit structure 22 moves to the inside of the soil collecting cover 16. After that, the lifting seat 11 drives the No. 1 limiting structure 152 to move upward, drives the guide posts 151 and the sliding seat 15 to move upward, and drives the soil collecting cover 16 to move upward. The crushed soil in the soil collecting cover 16 falls into the drill hole, covering the fertilizer, completing the drilling, sowing, fertilizing and covering work of one sowing position, completing the sowing work of one place, repeating the above work, and sowing the next sowing position;

[0065] The present sowing device automatically completes the operations of drilling, sowing, fertilizing and covering, thereby improving the efficiency of the sowing device. During the upward movement of the lifting seat 11, the flipping mechanism 5 causes the baffle 14 to rotate, so that the fertilizer on the baffle 14 can enter the hole, so that the fertilizer and the seeds are separated by the broken soil, avoiding direct contact between the seeds and the fertilizer, reducing the chance of seed damage, and improving the germination rate of the seeds. By adjusting the working position of the flipping mechanism 5, the distance between the drill bit structure 22 and the bottom of the drill hole is adjusted when the baffle 14 rotates, and the distance between the fertilizer and the seed is adjusted, it is adapted to different seeds and fertilizers, thereby improving the adaptability of the sowing device. When the drill barrel 2 moves downward, the blocking mechanism 3 is in a blocking state, blocking the through hole 21, preventing broken soil from accumulating in the through hole 21 (or entering the drill barrel 2 through the through hole 21), ensuring that the seeds and fertilizer move smoothly through the through hole 21 into the drill hole, and improving the reliability of the sowing device.

[0069] The conveying cylinder 13 is slidably connected to the sliding cylinder 43; a first limiting groove is provided on the side wall of the upper end 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 first sliding post 46 is slidably connected to the connecting cylinder 44; a first limiting member 47 is provided at one end of the first sliding post 46; a first elastic member 48 is provided at the other end of the first sliding post 46; the first elastic member 48 is used to elastically support the first sliding post 46;

[0071] One of the taking parts 411 is provided with seed taking grooves 4131 at even intervals; the other taking part 411 is provided with a fertilizer taking groove 4141.

[0072] When the lifting seat 11 moves downward, it drives the conveying cylinder 13 to move downward, driving the sliding cylinder 43 to move downward (at this time, the elastic force of the No. 1 elastic member 48 makes the No. 1 limiting member 47 contact the No. 1 limiting groove, and the sliding cylinder 43 is fixedly connected to the conveying cylinder 13), driving the driving member 45 to move downward, and the driving member 45 exerts a downward force on the side wall of the driving groove 4121, and exerts a downward force on the horizontal portion 412, driving the picking portion 411 to move (before the picking portion 411 moves, the seed taking groove 4131 is located on the upper side of the square tube structure 121, and the seeds enter the seed taking groove 4131, and the fertilizer taking groove 4141 is located on the upper side of the square tube structure 121, and the fertilizer enters the seed taking groove 4131), driving the seeds and fertilizer to move, and when the picking portion 411 contacts the No. 2 limiting structure 4211 (the No. 2 limiting structure 4211 is provided on the No. 1 inclined portion 421), the picking When the lifting seat 11 stops moving, the seed taking groove 4131 moves to the outside of the square tube structure 121, and the seeds in the seed taking groove 4131 slide into the No. 1 inclined portion 421, pass through the No. 1 vertical portion 422, the sliding cylinder 43, and the conveying cylinder 13 enter the drilling cylinder 2, and the fertilizer taking groove 4141 moves to the outside of the square tube structure 121, and the fertilizer taking groove 4141 slides into the No. 1 inclined portion 421, passes through the No. 1 vertical portion 422 and the sliding cylinder 43 into the conveying cylinder 13, and accumulates above the baffle 14, automatically completing the seed and fertilizer taking work;

[0073] When the drilling is completed and the lifting seat 11 moves upward, it drives the conveying cylinder 13 to move upward, and drives the No. 1 driving member 45 to move upward. When the No. 1 driving member 45 is facing the No. 1 limiting groove, the elastic force of the No. 1 elastic member 48 causes the No. 1 driving member 45 to resist in the No. 1 limiting groove, so that the sliding cylinder 43 is fixedly connected to the conveying member, driving the sliding cylinder 43 to move upward, driving the driving member 45 to move upward, and the driving member 45 generates an upward force on the horizontal part 412, driving 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 taking groove 4131 is located on the upper side of the square tube structure 121, and the seeds enter the seed taking groove 4131, and the fertilizer taking groove 4141 is located on the upper side of the square tube structure 121, and the fertilizer enters the seed taking groove 4131.

[0077] After the drill tube 2 drills to the set depth and stops rotating, the controller makes the No. 4 motor 35 work, and the No. 4 connecting shaft 34 is driven to rotate forward through the No. 4 transmission member 36, driving the connecting plate 32 to move downward, and driving the blocking plate 31 downward through the connecting rod 33, so that the blocking plate 31 moves to the lowest position, so that the blocking plate 31 leaves the lower opening of the through hole 21, so that the through hole 21 is open, and it is convenient for seeds or fertilizers to move downward from the through hole 21; before the lifting mechanism 6 drives the lifting seat 11 to move downward, the controller makes the No. 4 motor 35 work, and drives the No. 4 connecting shaft 34 to rotate in the opposite direction through the No. 4 transmission member 36, driving the connecting plate 32 to move upward, and driving the blocking plate 31 to move upward through the connecting rod 33, so that the blocking plate 31 moves to a high position, so that the blocking plate 31 contacts the lower opening of the through hole 21, thereby blocking the through hole 21.

[0078] The conveying cylinder 13 includes a third vertical portion 131 and a third inclined portion 132; the third vertical portion 131 is slidably connected to the sliding cylinder 43; the third inclined portion 132 is rotatably connected to the baffle 14;

[0079] The flip 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] A third rotating shaft 51 is fixed to one end of the bezel 14 ; a stopper 141 is provided at the other end of the bezel 14 ; the third rotating shaft 51 is rotatably connected to the third inclined portion 132 ; the third rotating shaft 51 is rotatably connected to the third gear 52 ; and three grooves 521 are evenly spaced on the side surface of the third gear 52 ;

[0082] The frame 1 is slidably connected to the sliding member 53; the sliding member 53 is fixed with the third rack 54; the frame 1 is rotatably connected to the third connecting shaft 55; 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 portion 132.

[0083] During the downward movement of the sliding seat 15, when the No. 3 gear 52 is meshed with the No. 3 rack 54, the No. 3 gear 52 rotates counterclockwise, and the inner wall of the No. 3 groove 521 generates a force on the No. 3 limiter 58 (at this time, the elastic force of the No. 3 elastic member 59 causes the No. 3 limiter 58 to abut against one of the No. 3 grooves 521), so that the No. 3 limiter 58 generates a force to rotate with the No. 3 gear 52, so that the No. 3 connecting portion 511 generates a force to rotate counterclockwise, so that the No. 3 rotating shaft 51 generates a force to rotate counterclockwise, so that the baffle 14 generates a force to rotate counterclockwise, and at this time the limiter 141 abuts against the inner wall of the third inclined portion 132, preventing the baffle 14 from rotating counterclockwise. This resists the elastic force of the third elastic member 59, causing the third limiting member 58 to disengage from the third groove 521, thereby forming a rotational connection between the third gear 52 and the third connecting portion 511. As the third gear 52 rotates counterclockwise, the baffle 14 remains stationary, preventing the baffle 14 from rotating and causing the fertilizer to slip when the sliding seat 15 moves downward. When the third gear 52 separates from the third rack 54, the elastic force of the third elastic member 59 causes the third limiting member 58 to abut against one of the third grooves 521 again.

[0084] During the upward movement of the sliding seat 15, when the No. 3 gear 52 meshes with the No. 3 rack 54, the No. 3 gear 52 rotates clockwise, and the inner wall of the No. 3 groove 521 generates a force on the No. 3 limiter 58, causing the No. 3 limiter 58 to generate a force to rotate with the No. 3 gear 52, causing the No. 3 connecting portion 511 to generate a force to rotate clockwise, causing the No. 3 rotating shaft 51 to generate a force to rotate clockwise, causing the baffle 14 to generate a force to rotate clockwise, resisting the force of the No. 3 elastic plate 56, causing the baffle 14 to rotate clockwise, causing the fertilizer above the baffle 14 to slide downward, allowing the fertilizer to enter the drill tube 2;

[0085] When the third gear 52 is not engaged with the third rack 54, the third elastic plate 56 causes the limiting portion 141 at one end of the baffle 14 to contact the inner wall of the third inclined portion 132. The baffle 14 blocks the third inclined portion 132 to prevent the fertilizer from sliding off.

[0086] Rotating the No. 3 connecting shaft 55 drives the sliding member 53 to slide, drives the No. 3 rack 54 to move, adjusts the meshing position of the No. 3 gear 52 and the No. 3 rack 54, adjusts the distance between the drill bit structure 22 and the bottom of the drill hole when the baffle 14 rotates, adjusts the distance between the fertilizer and the seed, adapts to different seeds and fertilizers, and improves the adaptability of the sowing device.
