Abstract
Description
Technical Field
[0001] This utility model relates to the field of peanut planting technology, and in particular to a peanut planter. Background Technology
[0002] Peanuts are usually sown in the spring. When the temperature is stable above 15℃, you can start sowing. Select plump and disease-free seeds. Before sowing, you can soak them to promote germination and improve the germination rate. After sowing, cover them with soil and press lightly, and keep the soil moist. Seedlings will emerge in about 7 to 10 days.
[0003] A search revealed a novel peanut planter disclosed in Chinese Patent Publication No. CN220674321U. This practical planter features a furrowing plow and a furrowing plow connector fixed to the bottom of the frame via bolts. Both the furrowing plow and the connector have two rows of six bolt holes, allowing for height adjustment via bolt connection for convenient field operation. When actually in the field, the furrowing plow can be lower than the casters, enabling the planting of two rows of peanuts at once.
[0004] While the aforementioned patent allows for adjusting the height of the furrowing plow by connecting it to the furrowing plow connector with bolts, the uneven surface of the land during furrowing makes it difficult to flexibly adjust the plow height according to the ground conditions. When the uneven ground causes the planter to wobble, the furrows created by the plow will vary in depth, affecting the depth of seed sowing. If sown too shallowly, the seeds are easily exposed on the surface and susceptible to adverse environmental influences; if sown too deeply, the seeds may not sprout, resulting in gaps in the rows and ultimately impacting peanut yield and quality. Therefore, this paper proposes a peanut planter to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3This utility model provides an embodiment of a peanut planter, including a frame 1. A support rod 2 is fixedly connected to the bottom of the frame 1. A traveling wheel 3 is rotatably connected to the side wall of the support rod 2. The traveling wheel 3, in conjunction with the support rod 2, allows the frame 1 to move above the ground. A hopper 4 is fixedly connected to the inner wall of the frame 1. Before planting, peanut seeds need to be poured into the hopper 4 for storage, and the amount of peanut seeds stored cannot exceed the rotating rod 61. An adaptive furrowing mechanism 5 is provided on the left side of the frame 1, and a feeding mechanism 6 is provided inside the hopper 4.
[0034] Reference Figures 1-3 The adaptive ditching mechanism 5 includes a slide rod 51, which is slidably connected to the inner wall of the frame 1. A pulley 52 is rotatably connected to the bottom inner wall of the slide rod 51. As the slide rod 51 moves, it drives the pulley 52 to roll against the ground. When the ground is uneven, the pulley 52 will move the slide rod 51 up and down along the inner wall of the frame 1 according to the unevenness of the ground. A curved rod 53 is slidably connected to the inner wall of the slide rod 51. A ditching plow 54 is fixedly connected to the bottom end of the curved rod 53. As the curved rod 53 slides, it drives the ditching plow 54 to move synchronously, thereby adjusting the height of the ditching plow 54. By adjusting the height of the ditching plow 54, it can dig trenches of different depths. A threaded rod 55 is rotatably connected through the inner wall of slide rod 51. The threaded rod 55 is threadedly connected to the bent rod 53. A handle 56 is fixedly connected to the top of the threaded rod 55. By rotating the threaded rod 55 through the handle 56, the bent rod 53 connected to it can slide on the inner wall of slide rod 51. A covering rake 57 is fixedly connected to the outer wall of bent rod 53. Two sets of covering rakes 57 are set. The two sets of covering rakes 57 are mirror images of each other on the left and right sides of bent rod 53 with pulley 52 as the central axis. While slide rod 51 moves, the two sets of covering rakes 57 can push the soil produced by the furrowing plow 54 back into the furrow to bury the peanut seeds in the furrow.
[0035] Reference Figure 2 , Figure 4 and Figure 5The feeding mechanism 6 includes a rotating rod 61, which is rotatably connected to the inner wall of the hopper 4. A connecting rod 62 is fixedly connected to the outer wall of the rotating rod 61. A feeding scoop 63 is fixedly connected to the end of the connecting rod 62 away from the rotating rod 61. The connecting rod 62 drives the feeding scoop 63 to rotate around the rotating rod 61. The feeding scoop 63 is inclined at the end of the rotating rod 61. The side of the feeding scoop 63 closest to the inner wall of the hopper 4 has an open structure. The open end of the feeding scoop 63 is in contact with the inner wall of the hopper 4. When the feeding scoop 63 moves below the rotating rod 61, it scoops up the peanut seeds stored inside the hopper 4, allowing the peanut seeds to enter the interior of the feeding scoop 63. Because the open end of the feeding scoop 63 is in contact with the inner wall of the hopper 4, after the feeding scoop 63 scoops up the peanut seeds, its open end will be closed by the inner wall of the hopper 4, thus allowing the peanut seeds to remain within the scoop 63 during its movement. Finally, inside the hopper 4, a motor 64 is fixedly connected to the left side, and the left end of the rotating rod 61 is fixedly connected to the output end of the motor 64. When the motor 64 is started, the rotating rod 61 is driven to rotate. When the rotating rod 61 rotates, it will drive the connecting rod 62 to move synchronously. Both the left and right sides of the hopper 4 have openings 65. The inner wall of the opening 65 is fixedly connected to the guide rail 66. When the opening end of the scoop 63 moves into the opening 65, the peanut seeds inside the scoop 63 will slide down because the scoop 63 is tilted at the end of the connecting rod 62. The scoop 63 slides out of the opening end of the scoop 63. The end of the guide rail 66 away from the opening 65 gradually tilts downward and extends between the two sets of covering rakes 57. Guided by the guide rail 66, the peanut seeds can fall between the two sets of covering rakes 57, so that the peanut seeds can enter the trench opened by the furrowing plow 54.
[0036] Working principle: The frame 1 can move above the ground using the walking wheels 3 and the support rod 2. While the frame 1 moves, the furrowing plow 54 can dig furrows in the ground so that peanut seeds can be planted in the furrows. At the same time, the movement of the frame 1 will drive the sliding rod 51 to move synchronously. As the sliding rod 51 moves, it will drive the pulley 52 to roll against the ground. When the ground is uneven, the pulley 52 will drive the sliding rod 51 to slide up and down on the inner wall of the frame 1 according to the unevenness of the ground. As the sliding rod 51 slides up and down, it can drive the furrowing plow 54 to move up and down synchronously with the connecting rod 62. The up and down movement of the furrowing plow 54 can dig furrows of equal depth according to the unevenness of the ground, so that the peanut seeds can be buried at an appropriate depth, which is beneficial to improving the survival rate of peanut seeds.
[0037] By rotating the threaded rod 55 through the handle 56, the rotation of the threaded rod 55 can drive the bent rod 53 connected to it to slide on the inner wall of the slide rod 51. As the bent rod 53 slides, it will drive the furrowing plow 54 to move synchronously, thereby adjusting the height of the furrowing plow 54. By adjusting the height of the furrowing plow 54, it can make furrows of different depths, so that the depth of the furrows can be freely adjusted according to the soil conditions or actual sowing requirements.
[0038] During the trenching process, the trenching plow 54 pushes excess soil to both sides of the trenching plow 54. As the frame 1 moves, the sliding rod 51 and the curved rod 53 can drive the covering rake 57 to move synchronously. The movement of the covering rake 57 can push the soil pushed away by the trenching plow 54 back into the trench, thereby burying the peanut seeds inside the trench.
[0039] Pour peanut seeds into the hopper 4, but the pile height should not exceed the rotating rod 61. While the frame 1 moves to plant the seeds, start the motor 64 to rotate the rotating rod 61. The rotation of the rotating rod 61 will simultaneously move the connecting rod 62. At this time, the connecting rod 62 will cause the feeding scoop 63 to rotate around the rotating rod 61. When the feeding scoop 63 moves below the rotating rod 61, it will scoop up the peanut seeds stored in the hopper 4, allowing them to enter the feeding scoop 63. As the feeding scoop 63 continues to move, it will gradually bring the peanut seeds inside it closer to the opening 65. When the open end of the feeding scoop 63 moves into the opening 65, the seeds will be released from the hopper. The feeding scoop 63 is tilted at the end of the connecting rod 62, so the peanut seeds inside the feeding scoop 63 will slide down and out of the feeding scoop 63 through the open end of the feeding scoop 63. At the same time, the peanut seeds will slide out of the hopper 4 through the opening 65. At this time, the guide rail 66 can guide the peanut seeds sliding out of the opening 65, so that the peanut seeds fall between the two sets of covering rakes 57, so that the peanut seeds can enter the furrow opened by the furrowing plow 54. Then, the covering rake 57 will cover the peanut seeds with soil, thus completing the automatic sowing of peanut seeds. The entire peanut planting process does not require manual operation, making it more convenient to use and greatly improving the efficiency of peanut planting.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
