After the lifting frame moves upward for a certain distance, the controller makes the first power mechanism suspend work again, and at the same time makes the angle motor work again, so that the rotating shaft rotates in the opposite direction for one circle, and the seed taking part is driven to work once by the first transmission mechanism. The seed taking part makes the seeds move into the first conveying member, slide into the drill barrel, fall into the hole through the drop hole, and the first power mechanism drives the lifting frame to move upward. When the drill head structure moves upward, the soil falls downward to cover the seeds. After the lifting frame moves upward for a certain distance, the controller makes the first power mechanism suspend work again, and at the same time makes the angle motor work again, so that the rotating shaft rotates in the opposite direction for one circle, and The mechanism drives the fertilizer taking part to work once, and the fertilizer taking part makes the fertilizer move into the No. 2 conveying part, slide into the drill tube, fall into the hole through the drop hole, and move the lifting frame to the highest position. When the lifting frame moves upward, it drives the bottom plate structure to move upward. When the bottom plate structure contacts the limiting structure, the drill bit structure moves to the inside of the soil collecting cover, and the bottom plate structure drives the limiting structure to move upward, drives the guide column and the sliding seat to move upward, drives the soil collecting cover to move upward, and the soil in the soil collecting cover falls into the hole to cover 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 to sow at the next sowing position; automatically completing the drilling, sowing, fertilizing and covering work, improving the convenience of the sowing device; when the drill bit structure moves upward, the soil will fall downward, so the fertilizer and the seeds are separated by the soil, avoiding direct contact between the seeds and the fertilizer, reducing the probability of seed damage, and improving the germination rate of the seeds.

[0026] 2. In the present invention, some seeds and fertilizers need to be compacted after being covered with soil, so that the retaining structure is moved to the bottom of the soil collecting cover, and then the No. 1 power mechanism causes the lifting frame to repeatedly move downward and upward. When the lifting frame moves downward, the sliding seat moves downward, driving the soil collecting cover and the sliding plate to move downward, driving the retaining structure to move downward, so that the retaining structure is squeezed on the soil, the soil is compacted, and artificial compaction is avoided, thereby improving the adaptability of the device.

[0027] 3. In the present invention, during the forward rotation of the driving shaft, the seeds in the No. 1 holding groove are driven to move obliquely downward, and the seeds fall into the No. 1 conveying member when they move to the outside of the No. 1 square tube structure. After the seed taking member moves to the lowest point, the seed taking member is moved to the highest point, so that the fixing member contacts the seeds in the No. 1 holding member, and the seeds enter the No. 1 holding groove, completing a seed taking work; during the reverse rotation of the driving shaft, the fertilizer in the No. 2 holding groove is driven to move obliquely downward, and the fertilizer falls into the No. 2 conveying member when it moves to the outside of the No. 2 square tube structure. After the fertilizer taking member moves to the lowest point, the No. 1 transmission mechanism drives the fertilizer taking member to move obliquely upward, so that the fertilizer taking member moves to the highest point, and the fertilizer enters the No. 2 holding groove, completing a fertilizer taking work.

[0028] 4. In the present invention, the driving shaft drives the No. 1 rotating member to rotate forwardly one circle during one circle rotation, and the No. 1 rotating member drives the No. 1 connecting shaft to rotate forwardly one circle. When the No. 1 connecting shaft just starts to rotate, the No. 1 driving member is located at the connection between the upper ends of the two No. 1 driving grooves, so that the No. 1 driving member moves obliquely downward along the axis direction of the No. 1 connecting shaft, driving the seed taking member to move obliquely downward. When the No. 1 connecting shaft rotates half a circle, the No. 1 driving member moves to the connection between the lower ends of the two No. 1 driving grooves, and the seed taking member moves to the lowest point. The No. 1 connecting shaft continues to rotate, so that the No. 1 driving member moves obliquely upward along the axis direction of the No. 1 connecting shaft, driving the seed taking member to move obliquely upward. When the No. 1 connecting shaft rotates one full circle, it stops rotating, and the No. 1 driving member moves to the connection between the upper ends of the two No. 1 driving grooves again, and the seed taking member moves to the highest point, completing one seed taking operation. Working: During the process of the driving shaft rotating one circle in the opposite direction, it drives the No. 2 rotating member to rotate one circle in the opposite direction, and the No. 2 rotating member drives the No. 2 connecting shaft to rotate one circle in the opposite direction. When the No. 2 connecting shaft just starts to rotate, the No. 2 driving member is located at the connection between the upper ends of the two No. 2 driving grooves, so that the No. 2 driving member moves diagonally downward along the axis direction of the No. 2 connecting shaft, and drives the fertilizer taking member to move diagonally downward. When the No. 2 connecting shaft rotates half a circle, the No. 2 driving member moves to the connection between the lower ends of the two No. 2 driving grooves, and the fertilizer taking member moves to the lowest point. The No. 2 connecting shaft continues to rotate, so that the No. 2 driving member moves diagonally upward along the axis direction of the No. 2 connecting shaft, and drives the fertilizer taking member to move diagonally upward. When the No. 2 connecting shaft rotates one full circle, it stops rotating, and the No. 2 driving member moves to the connection between the upper ends of the two No. 2 driving grooves again, and the fertilizer taking member moves to the highest point, completing one fertilizer taking work.

[0053] A No. 1 containing box 11 and a No. 2 containing box 12 are fixedly connected to the lifting frame 6; a seed taking piece 3 is connected to the lower part of the No. 1 containing box 11; a No. 1 conveying piece 13 is fixedly connected to the lower end of the No. 1 containing box 11; a fertilizer taking piece 4 is connected to the lower part of the No. 2 containing box 12; a No. 2 conveying piece 14 is fixedly connected to the lower end of the No. 2 containing box 12; the No. 1 containing box 11 is used to hold seeds; the No. 2 containing box 12 is used to hold fertilizers;

[0054] The lifting frame 6 is rotatably connected with a driving shaft 15; the seed taking piece 3 and the driving shaft 15 are driven by a No. 1 transmission mechanism 7; the fertilizer taking piece 4 and the driving shaft 15 are driven by a No. 1 transmission mechanism 7; the lifting frame 6 is fixedly connected with an angle motor 16; the driving shaft 15 is synchronously rotatably connected with the rotating shaft of the angle motor 16;

[0055] A sliding seat 17 is connected to the lower part of the lifting frame 6; guide posts 18 are evenly spaced on the sliding seat 17; the lower end of the guide post 18 is fixedly connected to the sliding seat 17; a limiting structure 181 is provided on the upper end of the guide post 18; the guide post 18 is slidably connected to the bottom plate structure 61; the lower end of the sliding seat 17 is fixedly connected to the soil collecting cover 5; a baffle 19 is fixedly connected to the sliding seat 17; a No. 1 through hole 191 is provided on the baffle 19; the drill tube 2 passes through the No. 1 through hole 191;

[0056] A power mechanism No. 1 81 is connected to the frame 1; the power mechanism No. 1 81 is used to drive the lifting frame 6 to rise or fall; the lifting frame 6 is connected to a power mechanism No. 2 82; the power mechanism No. 2 82 is used to drive the drill tube 2 to rotate; a walking mechanism 83 is connected to the bottom of the frame 1; the walking mechanism 83 is used to drive the frame 1 to move.

[0057] During operation, the user operates the walking mechanism 83 through the controller, and the walking mechanism 83 drives the frame 1 to move, so that the sowing device moves to the sowing position. Then the user causes the controller to execute the sowing program, and the controller operates the No. 1 power mechanism 81, and the No. 1 power mechanism 81 drives the lifting frame 6 to move downward, so that the drill tube 2, the sliding seat 17 and the soil collecting cover 5 are close to the ground. After the lower end of the soil collecting cover 5 contacts the ground, the lifting frame 6 continues to move downward. Since the lower end of the soil collecting cover 5 contacts the ground, the soil collecting cover 5 remains stationary. While the lifting frame 6 continues to move downward, the controller operates the No. 2 power mechanism 82, and the No. 2 power mechanism 82 drives the drill tube 2 to rotate, so that the drill tube 2 rotates while moving downward, and the drill bit structure 21 contacts the ground and contacts the soil. The soil is drilled into the soil, and the soil collecting cover 5 stores the drilled soil. After the drilling depth of the drill bit structure 21 reaches the sowing requirement, the controller stops the operation of the No. 1 power mechanism 81 and the No. 2 power mechanism 82, and operates the angle motor 16, so that the rotating shaft of the angle motor 16 rotates one circle in the forward direction (the rotating shaft of the angle motor 16 can only rotate one circle in the forward direction or one circle in the reverse direction each time it works), and drives the driving shaft 15 to rotate one circle in the forward direction. When the driving shaft 15 rotates in the forward direction, the No. 1 transmission mechanism 7 drives the seed taking part 3 to work once, and the seed taking part 3 moves the seeds into the No. 1 conveying part 13, slides into the drill tube 2, and falls into the hole through the drop hole 211. Then the controller operates the No. 1 power mechanism 81 again, and the No. 1 power mechanism 81 drives the lifting frame 6 to move upward. The drill tube 2 is driven to move upward, and the drill bit structure 21 is driven to move upward. When the drill bit structure 21 moves upward, the soil falls downward to cover the seeds. After the lifting frame 6 moves upward for a certain distance, the controller makes the No. 1 power mechanism 81 stop working again, and at the same time makes the corner motor 16 work again, so that its rotating shaft rotates in the opposite direction for one circle, and drives the driving shaft 15 to rotate in the opposite direction for one circle. When the driving shaft 15 rotates in the opposite direction, it drives the fertilizer taking part 4 to work once through the No. 1 transmission mechanism 7. The fertilizer taking part 4 moves the fertilizer into the No. 2 conveying part 14, and slides into the drill tube 2, and falls into the hole through the drop hole 211. Then the controller makes the No. 1 power mechanism 81 work, so that the lifting frame 6 moves to the highest position. When the lifting frame 6 moves upward, it drives the bottom plate structure 61 to move upward. When the bottom plate structure When 61 contacts the limiting structure 181, the drill bit structure 21 moves to the inside of the soil collecting cover 5, and the bottom plate structure 61 drives the limiting structure 181 to move upward, drives the guide column 18 and the sliding seat 17 to move upward, drives the soil collecting cover 5 to move upward, and the soil in the soil collecting cover 5 falls into the hole to cover the fertilizer, completing the drilling, sowing, fertilizing and covering work at one sowing position, completing the sowing work at one place, repeating the above work to sow at the next sowing position; automatically completing the drilling, sowing, fertilizing and covering work, improving the convenience of the sowing device; when the drill bit structure 21 moves upward, the soil will fall downward, so the fertilizer and the seeds are separated by the soil, avoiding direct contact between the seeds and the fertilizer, reducing the probability of seed damage, and improving the germination rate of the seeds;The distance between the fertilizer and the seed can be adjusted according to the rising distance of the drill structure 21, so as to adapt to different seeds and fertilizers and improve the adaptability of the sowing device.

[0058] A first sliding groove 51 is provided at the lower end of the soil collecting cover 5; a sliding plate 52 is slidably connected to the soil collecting cover 5; a retaining structure 521 is provided at the lower end of the sliding plate 52; the retaining structure 521 is slidably connected in the first sliding groove 51; a counterweight 53 is provided at one side of the soil collecting cover 5; the counterweight 53 is fixedly connected to the sliding seat 17;

[0060] Some seeds and fertilizers need to be compacted after being covered with soil. The user causes the controller to execute the sowing program and the compaction program. After the sowing program is completed, after the lifting frame 6 moves to the top, the controller automatically executes the compaction program.

[0071] During the process of the drive shaft 15 rotating one circle in the forward direction, the drive shaft 15 drives the No. 1 connecting member 77 and the No. 2 connecting member 78 to rotate forwardly. When the No. 1 connecting member 77 rotates forwardly, it drives the No. 1 ball 773 to rotate forwardly (in the initial state, the No. 1 ball 773 abuts against the No. 1 limiting structure 181, the No. 2 ball 783 abuts against the No. 2 limiting structure 181, the No. 3 ball 622 abuts against the No. 3 limiting groove, and the No. 4 ball 632 abuts against the No. 4 limiting groove). The No. 1 ball 773 abuts against the No. 1 limiting structure 181, and the No. 1 ball 773 generates a force on the No. 1 limiting structure 181, so that the No. 1 rotating member 72 generates a rotational force, overcomes the elastic force of the No. 3 elastic member 623, causes the No. 3 ball 622 to disengage from the No. 3 limiting groove, and causes the No. 1 rotating member 72 to rotate. The movable member 72 is rotatably connected with the lifting frame 6, driving the No. 1 rotating member 72 to rotate, so that the No. 1 rotating member 72 rotates synchronously with the driving shaft 15. When the driving shaft 15 and the No. 1 rotating member 72 rotate a full circle and stop rotating, the No. 3 limiting groove rotates to a position directly opposite to the No. 3 ball 622. The elastic force of the No. 3 elastic member 623 causes the No. 3 sliding column 621 and the No. 3 ball 622 to move outward, so that the No. 3 ball 622 again abuts against the No. 3 limiting groove, so that the No. 1 rotating member 72 and the lifting frame 6 are fixedly connected again. When the No. 2 connecting member 78 rotates forwardly, it drives the No. 2 ball 783 to rotate forwardly. At this time, the No. 4 ball 632 abuts against the No. 4 limiting groove, so that the No. 2 rotating member 75 and the lifting frame 6 are fixedly connected, so that the No. 2 rotating member 75 remains stationary, and the driving shaft 1 When the No. 2 ball 783 is about to rotate one circle, it abuts against the No. 2 slope structure 7511, and the No. 2 ball 783 causes the No. 2 slope structure 7511 to generate a rotation force, so that the No. 2 rotating member 75 generates a rotational force. Since the No. 4 ball 632 abuts against the No. 4 limiting groove, the No. 4 ball 632 prevents the No. 2 rotating member 75 from rotating. The rotational force of the No. 2 rotating member 75 is less than the rotational resistance, so that the No. 2 ball 783 and the No. 2 sliding column 782 move into the No. 2 mounting groove 781, so that the No. 2 ball 783 moves along the No. 2 slope structure 7511, so that the driving shaft 15 continues to rotate. When the driving shaft 15 rotates one circle and stops rotating, the No. 2 ball 783 just passes over the No. 2 slope structure 7511 and moves to the No. 2 slope structure 7511 under the elastic force of the No. 2 elastic member 784. The mounting groove 781 moves outward, so that the No. 2 ball 783 hits the side wall of the No. 2 connecting groove 751 again. During this process, the No. 2 rotating member 75 always remains stationary. During the process of the driving shaft 15 rotating one circle in the forward direction, it drives the No. 1 rotating member 72 to rotate one circle in the forward direction (the No. 2 rotating member 75 always remains stationary). At the same time, the No. 1 rotating member 72 drives the No. 1 connecting shaft 71 to rotate one circle in the forward direction through the No. 1 transmission member 91. When the No. 1 connecting shaft 71 just starts to rotate, the No. 1 driving member 73 is located at the connection between the upper ends of the two No. 1 driving grooves 711. When the No. 1 connecting shaft 71 rotates, the side wall of the No. 1 driving groove 711 generates a thrust on the No. 1 driving member 73, so that the No. 1 driving member 73 moves obliquely downward along the axial direction of the No. 1 connecting shaft 71, driving the seed taking member 3 to move obliquely downward.When the No. 1 connecting shaft 71 rotates half a circle, the No. 1 driving member 73 moves to the connection between the lower ends of the two No. 1 driving grooves 711, and the seed removing member 3 moves to the lowest position. The No. 1 connecting shaft 71 continues to rotate, so that the No. 1 driving member 73 enters another No. 1 driving groove 711, and the side wall of the other No. 1 driving groove 711 generates a thrust on the No. 1 driving member 73, so that the No. 1 driving member 73 moves obliquely upward along the axial direction of the No. 1 connecting shaft 71, driving the seed removing member 3 to move obliquely upward. When the No. 1 connecting shaft 71 rotates a full circle, it stops rotating, and the No. 1 driving member 73 moves to the connection between the upper ends of the two No. 1 driving grooves 711 again, and the seed removing member 3 moves to the highest position, completing a seed removing operation.

[0072] During the process of the driving shaft 15 rotating in the opposite direction for one circle, the driving shaft 15 drives the No. 1 connecting member 77 and the No. 2 connecting member 78 to rotate in the opposite direction. When the No. 2 connecting member 78 rotates in the opposite direction, it drives the No. 2 ball 783 to rotate in the opposite direction (in the initial state, the No. 1 ball 773 abuts against the No. 1 limiting structure 181, the No. 2 ball 783 abuts against the No. 2 limiting structure 181, the No. 3 ball 622 abuts against the No. 3 limiting groove, and the No. 4 ball 632 abuts against the No. 4 limiting groove). The No. 2 ball 783 abuts against the No. 2 limiting structure 181, and the No. 2 ball 783 generates a force on the No. 2 limiting structure 181, so that the No. 2 rotating member 75 generates a rotational force, overcomes the elastic force of the No. 4 elastic member 633, causes the No. 4 ball 632 to disengage from the No. 4 limiting groove, and causes the No. 2 rotating member 75 to rotate. The movable member 75 is rotatably connected with the lifting frame 6, driving the No. 2 rotating member 75 to rotate, so that the No. 2 rotating member 75 rotates synchronously with the driving shaft 15. When the driving shaft 15 and the No. 2 rotating member 75 rotate a full circle and stop rotating, the No. 4 limiting groove rotates to a position directly opposite to the No. 4 ball 632. The elastic force of the No. 4 elastic member 633 causes the No. 4 sliding column 631 and the No. 4 ball 632 to move outward, so that the No. 4 ball 632 again abuts against the No. 4 limiting groove, so that the No. 2 rotating member 75 and the lifting frame 6 are fixedly connected again. When the No. 1 connecting member 77 rotates in the opposite direction, it drives the No. 1 ball 773 to rotate in the opposite direction. At this time, the No. 3 ball 622 abuts against the No. 3 limiting groove, so that the No. 1 rotating member 72 is fixedly connected with the lifting frame 6, so that the No. 1 rotating member 72 remains stationary, and the driving shaft 1 When the No. 1 ball 773 is about to rotate one circle, when it abuts against the No. 1 slope structure 7211, the No. 1 ball 773 causes the No. 1 slope structure 7211 to generate a rotational force, so that the No. 1 rotating member 72 generates a rotational force. Since the No. 3 ball 622 abuts against the No. 3 limit groove, the No. 3 ball 622 hinders the No. 1 rotating member 72 from rotating. The rotational force of the No. 1 rotating member 72 is less than the rotational resistance, so that the No. 1 ball 773 and the No. 1 sliding column 772 move into the No. 1 installation groove 771, so that the No. 1 ball 773 moves along the No. 1 slope structure 7211, so that the driving shaft 15 continues to rotate. When the driving shaft 15 rotates one circle and stops rotating, the No. 1 ball 773 just passes over the No. 1 slope structure 7211 and moves to the No. 1 slope structure 7211 under the elastic force of the No. 1 elastic member 774. The mounting groove 771 moves outward, so that the No. 1 ball 773 hits the side wall of the No. 1 connecting groove 721 again. During this process, the No. 1 rotating member 72 always remains stationary. During the process of the driving shaft 15 rotating in the opposite direction, it drives the No. 2 rotating member 75 to rotate in the opposite direction for one circle (the No. 1 rotating member 72 always remains stationary). At the same time, the No. 2 rotating member 75 drives the No. 2 connecting shaft 74 to rotate in the opposite direction for one circle through the No. 2 transmission member 92. When the No. 2 connecting shaft 74 just starts to rotate, the No. 2 driving member 76 is located at the connection between the upper ends of the two No. 2 driving grooves 741. When the No. 2 connecting shaft 74 rotates, the side wall of the No. 2 driving groove 741 generates a thrust on the No. 2 driving member 76, so that the No. 2 driving member 76 moves obliquely downward along the axial direction of the No. 2 connecting shaft 74, driving the fertilizer taking member 4 to move obliquely downward.When the No. 2 connecting shaft 74 rotates half a circle, the No. 2 driving member 76 moves to the connection point at the lower ends of the two No. 2 driving grooves 741, and the fertilizer taking member 4 moves to the bottom. The No. 2 connecting shaft 74 continues to rotate, so that the No. 2 driving member 76 enters another No. 2 driving groove 741. The side wall of the other No. 2 driving groove 741 generates thrust on the No. 2 driving member 76, so that the No. 2 driving member 76 moves diagonally upward along the axis direction of the No. 2 connecting shaft 74, driving the fertilizer taking member 4 to move diagonally upward. When the No. 2 connecting shaft 74 rotates a full circle, it stops rotating, and the No. 2 driving member 76 moves to the connection point at the upper ends of the two No. 2 driving grooves 741 again, and the fertilizer taking member 4 moves to the top, completing a fertilizer taking operation.
