Description

Technical Field

[0001] The invention relates to the technical field of peanut planting, and in particular to a peanut single-grain precision sowing and positioning fertilization seeder. Background Art

[0002] Traditional peanut cultivation methods typically sow 2 to 4 seeds per hole, requiring a high seed dosage of up to 25 kg of peel (15 kg of kernel) per mu. In contrast, single-seed precision sowing significantly reduces seed usage while maintaining yield. For example, based on a basic seedling yield of 1,000 kg per mu, single-seed precision sowing requires approximately 13 kg of seed, while multi-seed hole sowing requires approximately 16 kg. Therefore, a minimum seed saving of approximately 3 kg per mu can be achieved, saving approximately 20%.

[0003] With traditional multi-seed hole sowing, multiple seeds are planted in one hole, leading to intense competition between underground roots and aboveground leaves. This competition not only limits the growth and development of individual plants but can also lead to uneven seedlings, reducing the quality of the peanut population. Single-seed precision sowing, on the other hand, reduces competition between plants by reducing the number of seeds sown in each hole and increasing plant spacing to ensure non-overlapping fruiting areas and minimal root crossing.

[0004] Traditional peanut single-grain precision sowing machines include hand-push peanut spot seeders, combined seeders and many other peanut sowing equipment, all of which can achieve single-grain sowing of peanuts. However, current seeders all require varying degrees of manual control and cannot achieve completely automated sowing. In addition, existing seeders cannot achieve targeted fertilization.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to the embodiments.

[0041] Example 1:

[0042] Reference Figure 1-10, which is the first embodiment of the present invention, a peanut single-grain precision sowing and positioning fertilizing seeder, includes a rotating wheel 1 and a storage barrel 21 arranged above the rotating wheel 1, the storage barrel 21 is filled with a sufficient amount of peanut seeds, and the opening and closing discharge component includes a plurality of conical pieces 19 rotatably mounted on the outer ring wall of the rotating wheel 1, each four conical pieces 19 form a group, and the four conical pieces 19 of each group are closed around to form a conical cavity tube, and the conical cavity tube is pointed at one end away from the rotating wheel 1, which is convenient for smooth insertion into the soil. When one of the conical cavity tubes rotates to the bottom of the rotating wheel 1, the four conical pieces 19 composed of the conical cavity tube rotate open, which is convenient for forming a pit in the soil and allowing the peanut seeds to fall smoothly into the pit;

[0043] The intermittent feeding assembly includes a feeding seat 24 rotatably mounted at the center position of the circle on both sides of the rotating wheel 1, the inner cavity of one of the feeding seats 24 is connected to the inner cavity of the storage barrel 21, and an intermittent feeding disc 32 that rotates synchronously with the rotating wheel 1 is rotatably mounted in the feeding seat 24. The outer ring wall of the intermittent feeding disc 32 is provided with a plurality of arc-shaped feeding openings 33. Single peanut seeds fall into the corresponding arc-shaped feeding openings 33. The size of the arc-shaped feeding openings 33 is consistent with the size of a single peanut, so the problem of two peanuts entering the arc-shaped feeding openings 33 at the same time will not occur.

[0044] And with the rotation of the intermittent feeding disc 32, the peanut seeds fall into the sowing cavity formed by the rotation and opening of the corresponding four conical pieces 19, and finally fall into the pit formed by the rotation and opening of the corresponding four conical pieces 19. Since the intermittent feeding of the intermittent feeding disc 32 is carried out intermittently, and the process of the four conical pieces 19 being inserted into the soil and rotating and opening is carried out synchronously, a single peanut seed can complete the entire process of being taken and falling into the pit.

[0045] Example 2:

[0046] Reference Figure 1-6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: mounting rings 11 are fixedly installed at the center positions of both ends of the rotating wheel 1, a cavity is opened inside the rotating wheel 1, and the inner wall of the cavity penetrates the outer ring wall of the rotating wheel 1 to open a plurality of mounting openings 12, and a plurality of conical cavity cylinders are respectively and adaptively mounted in the corresponding mounting openings 12. A plurality of mounting seats 13 distributed in a regular hexagon are provided in the cavity, and rotating rollers 14 are rotatably mounted between the two opposite inner side walls of the plurality of mounting seats 13. A plurality of cylinders 15 are also vertically fixedly installed on the inner wall of the cavity, and a round rod 16 fixedly connected to the corresponding mounting seat 13 is slidably inserted in the plurality of cylinders 15. The inner diameter of the cylinder 15 is consistent with the outer diameter of the round rod 16, and the outer wall of the cylinder 15 penetrates the inner cavity to open an air hole for maintaining the air pressure balance in the cylinder 15 and for buffering the elastic expansion and contraction of the spring 17;

[0047] A spring 17 is installed between each mounting seat 13 and the corresponding cylinder 15, and is sleeved around the round rod 16. A telescopic rod 18 is vertically fixedly connected to the side of each mounting seat 13 close to the inner wall of the cavity. A first connector 110 is fixedly installed around the end of the telescopic rod 18 away from the mounting seat 13. A second connector is fixedly installed on the inner sidewall of each conical piece 19. A connecting rod 111 is provided between each first connector 110 and the corresponding second connector. One end of each connecting rod 111 is rotatably connected to the corresponding first connector 110, and the other end is rotatably connected to the corresponding second connector.

[0048] The final effect is that when the telescopic rod 18 descends, the corresponding conical piece 19 will be pushed to rotate outward and open through the first connecting head 110, the connecting rod 111 and the second connecting head, so that the single peanut falling into the feeding cavity can fall smoothly into the pit in the soil. When the telescopic rod 18 rises, the corresponding conical piece 19 will be pulled inward and closed through the first connecting head 110, the connecting rod 111 and the second connecting head to form a conical cavity tube, which is convenient for smooth insertion into the soil next time.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3:

[0051] Reference Figure 7-10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a top seat 2 is provided above the rotating wheel 1, and a storage barrel 21 is fixedly connected to the top seat 2. The bottom of the storage barrel 21 is connected to a discharge barrel provided below the top seat 2. The discharge barrel is funnel-shaped and has no dead angle for discharge, ensuring that the peanut seeds in the storage barrel 21 can fall into the discharge pipe 26 one by one. A sealing cover 22 is threadedly installed on the top of the storage barrel 21, and a rotating handwheel 23 is installed on the top of the sealing cover 22 to facilitate rotating the sealing cover 22 to open it. Two discharge seats 25 are fixedly installed between the material taking seat 24 and the top seat 2;

[0052] The bottom of the discharge barrel is connected with a discharge pipe 26, which is a Y-shaped split design. The inner diameter of the discharge pipe 26 is slightly larger than the outer diameter of the peanut seeds, so the peanut seeds will fall out one by one. At the same time, the discharge pipe 26 does not have any sharp-angle bends, so there will be no problem of two peanut seeds getting stuck. The bottom of the discharge pipe 26 extends into the two discharge seats 25 and is connected to the inner cavity of the feeding seat 24. A baffle 27 is provided at the opening of the feeding seat 24 to prevent the peanut seeds or fertilizer particles at the arc-shaped feeding port 33 above the intermittent feeding plate 32 from falling directly out of the feeding seat 24. A circular hole is provided in the center of the baffle 27 for the shaft sleeve 31 to pass through. At the same time, the baffle 27 and the mounting ring 11 are also rotatably installed, and the baffle 27 is fixedly installed on the inner wall of the feeding seat 24. A discharge pipe 28 is installed on the baffle 27;

[0053] The discharge pipe 28 is arranged at the bottom of the baffle 27, and a small hole of the same aperture size is opened through the connection position of the baffle 27 and the discharge pipe 28, so that the peanuts dropped from the arc-shaped feeding port 33 can fall into the discharge pipe 28. A synchronous shaft 29 is fixedly installed between the two feeding seats 24, and an arc-shaped head 210 is vertically fixedly installed on the outer shaft wall of the synchronous shaft 29. The curvature of the arc-shaped head 210 is specially designed to be able to effectively fit with the rotating roller 14 and facilitate the rotation of the rotating roller 14 around the arc-shaped head 210. The outer shaft wall of the synchronous shaft 29 is rotatably fitted with a sleeve 31, and the outer ring wall of the sleeve 31 is fixedly fitted with an intermittent feeding tray 32. A fixing rod 34 is fixedly installed between the outer ring wall of the sleeve 31 and the inner wall of the cavity.

[0054] The remaining structures are the same as those of Example 2.

[0055] Example 4:

[0056] Reference Figure 1 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: L-shaped connecting rods 42 are vertically fixedly installed at the center positions of both ends of the shell 41, a connecting seat 43 is installed between the two L-shaped connecting rods 42, and a fixed shaft is installed between the two opposite inner side walls of the connecting seat 43. The fixed shaft facilitates docking and mounting with traction equipment, such as the hook of a tractor for cultivating land.

[0057] The remaining structures are the same as those of Example 3.

[0058] Example 5:

[0059] Reference Figure 11, which is the fourth embodiment of the present invention. This embodiment is different from the fourth embodiment in that the adjustable fertilizing assembly includes a plurality of fertilizer tanks 52 arranged behind a plurality of conical cavity cylinders. The lower output ends of the fertilizer tanks 52 are connected to discharge pipes 53. Conical fertilizer cylinders 55 are installed in the inner cavities of the discharge pipes 53 in a lifting and sliding manner. The top and bottom of the conical fertilizer cylinders 55 are through-designed to facilitate the fertilizer particles or powder in the fertilizer tanks 52 to fall into the cavity of the conical fertilizer cylinders 55 due to gravity and be delivered to the soil surface or inside from the output port at the bottom of the conical fertilizer cylinders 55. The tops are all installed A solenoid valve assembly 56 is installed. The solenoid valve assembly 56 includes a first baffle fixed at the upper end of the conical fertilizer barrel 55. The first baffle is provided with a plurality of first discharge openings. The solenoid valve assembly 56 also includes a second baffle located in the inner cavity of the conical fertilizer barrel 55 and rotatable. The upper surface of the second baffle is in contact with the lower surface of the first baffle, and the second baffle is provided with a plurality of second discharge openings. When the second baffle is rotated until the plurality of second discharge openings coincide with the plurality of first discharge openings, the fertilizer particles or powder in the fertilizer tank 52 will smoothly pass through the conical fertilizer barrel 55 and be discharged from the bottom of the conical fertilizer barrel 55.

[0060] The adjustable fertilizing assembly also includes a carrier plate 51 fixedly mounted on the outer shell 41. The fertilizer tanks 52 are all mounted on the bottom of the carrier plate 51. The carrier plate 51 is provided with several feeding ports connected to the inner cavity of the fertilizer tank 52. The tops of the several feeding ports are covered with sealing covers, and the sealing covers are provided with air holes to ensure the air pressure balance in the fertilizer tank 52 and facilitate the discharge of fertilizer particles or powder. Several lifting cylinders 54 are also vertically fixedly mounted on the top of the carrier plate 51. The output ends of the lifting cylinders 54 are all extended into the corresponding discharge pipes 53 and are vertically fixedly mounted on the top of the conical fertilizing barrel 55.

[0061] The remaining structures are the same as those of Example 4.

[0062] Working principle of the present invention:

[0063] The first step is to dry the peanut seeds at least twice before shelling them. After shelling, carefully select the brightly colored, plump and bright first-grade rice as high-yield seeds, and pick out the insect-eaten, germinated, yellow-brown peanuts and third-grade rice that are not suitable for seeding. Do not use or use less second-grade rice. This can enhance seed vitality, make the seedlings emerge quickly, uniformly and completely. The fruit layer should be 8-10 cm thick and should be turned frequently. Do not place it on the cement floor to prevent Excessive sun exposure: To reduce the risk of stem rot, damping-off, underground grubs, wireworms, cutworms, and aphids that damage peanut seeds, flower buds, and pods, you can mix the seeds with a solution of Celexa and Mysoo, and sow them after the seed coat is dried. To increase the germination and emergence rates of seeds and enhance the nitrogen-fixing capacity of root nodules, you can also use 0.2-0.4% of the seed weight of ammonium molybdate to make a 0.4-0.6% solution, spray it directly on the seeds with a sprayer, and sow them after the seed coat is dried.

[0064] The second step is to first remove the sealing cover 22 from the top of the storage barrel 21 by rotating the hand wheel 23, and put the pre-processed peanut seeds into the inner cavity of the storage barrel 21, and then close the sealing cover 22 by rotating the hand wheel 23 again to prevent the peanut seeds in the storage barrel 21 from jumping out and falling out during the movement of the planter. Then, loosen the screws so that the shaft cylinder 44 and the connecting bent rod 45 can slide and adjust the relative insertion position, thereby adjusting the contact between the connecting seat 43 and the soil;

[0065] In the third step, the connecting seat 43, the L-shaped connecting rod 42 and the outer shell 41 are pulled by the traction equipment to push the rotating wheel 1 to move until one of the conical cavities is inserted into the soil. Since the two material-retrieving seats 24 remain stationary, the synchronous shaft 29 fixedly connected between the two material-retrieving seats 24 remains stationary, and the arc-shaped head 210 installed on the outer ring wall of the synchronous shaft 29 also remains stationary and always points vertically downward. The shaft sleeve 31 rotating on the synchronous shaft 29 is fixedly connected to the rotating wheel 1 through the fixing rod 34, so the shaft sleeve 31 is forced to rotate synchronously, thereby driving the intermittent material-retrieving tray 32 to rotate.

[0066] Since the discharge port of the storage barrel 21 is connected to the discharge pipe 26, the peanut seeds in the storage barrel 21 will naturally fall into the discharge pipe 26 due to gravity. However, due to the blocking of the outer ring wall of the intermittent feeding disc 32 and the inner ring wall of the feeding seat 24, the peanut seeds accumulated in the discharge pipe 26 will not fall into the feeding seat 24 temporarily. However, when one of the arc-shaped feeding ports 33 on the intermittent feeding disc 32 rotates to the uppermost position, since the discharge port at the bottom of the discharge pipe 26 is no longer blocked by the intermittent feeding disc 32, the peanut seeds at the bottom will fall down and just fall into the arc-shaped feeding port 33. Then, with the rotation of the intermittent feeding disc 32, the peanut seeds are rotated to the lowermost position of the feeding seat 24 and discharged from the discharge pipe 28 on the baffle plate 27 into the inner cavity of the rotating wheel 1.

[0067] In the fourth step, along with the rotation of the rotating wheel 1, several rotating rollers 14 inside will also be driven to rotate synchronously. When one of the rotating rollers 14 rotates to a rolling contact position with the arc head 210, the rotating roller 14 will be forced to squeeze the corresponding two springs 17. The spring 17 obtains elastic restoring force. At the same time, the rotating roller 14 will also be forced to squeeze the telescopic rod 18, so that the first connecting head 110 at the bottom of the telescopic rod 18 pushes the second connecting head through the connecting rod 111, that is, pushes the conical piece 19. At this time, the conical cavity tube at the bottom of the rotating wheel 1 is just inserted into the soil, and when the four conical pieces 19 constituting the conical cavity tube are synchronously pushed outward and expanded, a pit is formed in the soil for convenient peanut seed planting. The peanut seeds previously discharged from the discharge pipe 28 into the rotating wheel 1 fall to the mounting port 12 currently in the inner cavity of the rotating wheel 1 due to gravity, and finally fall into the pit.

[0068] When the rotating wheel 1 is pushed further, the rotating roller 14 rotates to a state where it no longer rolls in contact with the arc head 210. At this time, the elastic recovery of the spring 17 pushes the rotating roller 14 back to its original position, facilitating the next rolling contact with the arc head 210. At the same time, the telescopic rod 18 is pulled toward the center of the rotating wheel 1, thereby pulling the four conical pieces 19 inward through the first connecting head 110, the connecting rod 111 and the second connecting head to re-form the conical cavity, facilitating the next smooth reinsertion into the soil.

[0069] In the fifth step, while the peanut seeds are sown, several lifting cylinders 54 located on the carrier plate 51 are started synchronously, and according to specific fertilization requirements, including quick-acting fertilizer and slow-release fertilizer, quick-acting fertilizer is applied to the shallow soil, and slow-release fertilizer is applied to the soil 10-20 cm deep, that is, different categories of shallow fertilization or deep fertilization, the conical fertilization barrel 55 is pushed down to different heights. When shallow fertilization is applied, it is only necessary for the discharge port of the conical fertilization barrel 55 to be located 0-10 cm in the soil. When deep fertilization is applied, it is only necessary for the discharge port of the conical fertilization barrel 55 to be extended to 10-20 cm inside the soil. When the conical fertilization barrel 55 reaches the specified height, the solenoid valve assembly 56 is activated, and the fertilizer particles or powder in the fertilizer tank 52 are used by their own gravity to pass through the conical fertilization barrel 55 to complete the fertilization operation. In addition, with the cooperation of the outer shell 41 during walking, comprehensive fertilization of the pit can be achieved.

[0070] The sixth step is that during the continuous rolling forward of the rotating wheel 1, the traction speed, that is, the rotation speed of the rotating wheel 1, can be adjusted to adjust the depth of the planting pit dug by the conical cavity tube, so as to facilitate the planting of peanut seeds at different depths, ensuring that the probability of single seed planting is higher than 95%, and different fertilizer particles can be applied to different depths of soil layers.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
