Description

Technical Field

[0001] The embodiments of this utility model relate to the field of agricultural machinery technology, specifically to a no-till seeder. Background Technology

[0002] No-till planters are machines that replace manual steps such as sowing, fertilizing, and tilling, completing the process in one step. They are specifically used for cash crops suitable for large-scale cultivation, such as corn, soybeans, potatoes, and garlic. No-till planters mainly include corn planters, soybean planters, garlic planters, and potato planters.

[0003] Currently, a large amount of uncultivated land and previous crop residues exist in the summer-sown fields of the Huang-Huai-Hai region. Wheat stubble and scattered wheat straw seriously affect the sowing quality. The currently used seeders are arrow-shovel type, which have disadvantages such as poor consistency in sowing depth and poor soil backfilling effect. At the same time, the presence of wheat stubble leads to damage to corn seedlings by the two-spotted cutworm. Therefore, it is urgent to develop a corn seeder that integrates "no-till + stubble removal + sowing + compaction" to improve sowing efficiency, land adaptability, and sowing quality. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a no-till seeder, which solves the problems of improving seeding efficiency and land adaptability in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a no-till seeder, including a base, a monitoring terminal display screen is provided on the top of the base, a stubble-killing and ditching system is provided at the bottom of the base, and a sowing and compaction system is provided at the bottom of the base.

[0006] The stubble removal and trenching system includes a fixed plate and a drive motor. The bottom of the fixed plate is fixedly connected to the top of the base, and the top of the fixed plate is fixedly connected to the circumferential surface of the drive motor. A rotating disk is fixedly connected to the output end of the drive motor. A conveyor belt is provided on the circumferential surface of the rotating disk. A control shaft is rotatably connected inside the base. A stubble removal shaft is fixedly connected to the circumferential surface of the control shaft. A serrated stubble removal blade is slidably connected through the circumferential surface of the stubble removal shaft. A second control shaft is rotatably connected inside the base. A trenching shaft is fixedly connected to the circumferential surface of the second control shaft. A trenching rod is slidably connected through the circumferential surface of the trenching shaft.

[0007] For example, in at least one embodiment of the present invention, a no-till planter is provided, which further includes: a number of serrated stubble-removing blades arranged in a circumferential array along the circumference of the stubble-removing axis, and a number of grooving rods arranged in a circumferential array along the circumferential surface of the grooving axis. The purpose is to carry out large-area tillage by using multiple serrated stubble-removing blades and grooving shafts.

[0008] The base is equipped with an electric spiral adjustment mechanism at its bottom. The electric spiral adjustment mechanism includes a micro motor. The side of the micro motor is fixedly connected to the inside of the stubble-cutting shaft. The output end of the micro motor is rotatably connected to a threaded rod. A pushing cone is threadedly connected to the circumferential surface of the threaded rod. A connecting plate is fixedly connected to one end of the serrated stubble-cutting blade and the grooving rod. A limiting plate is fixedly passed through the circumferential surface of the threaded rod to achieve different planting depths.

[0009] The number of micro motors, pushing cones, and limiting plates is set to four, and they are symmetrical to each other along the vertical central axis of the fixed plate. The bottom of the connecting plate is located on the displacement trajectory of the pushing cones. The purpose is to stabilize and adjust the connecting plate by means of multiple pushing cones, so as to ensure that the movement of the pushing cones pushes and adjusts the connecting plate.

[0010] A reset spring is fixedly connected to the side of the connecting plate. The end of the reset spring away from the side of the connecting plate is fixedly connected to the inner wall of the stubble-removing shaft. The purpose of this is to ensure that the connecting plate can automatically reset and reduce manual intervention.

[0011] According to another aspect, at least one embodiment of the present invention also provides a no-till seeder, including a mounting plate, the bottom of which is fixedly connected to the top of a base, a seeding motor fixedly connected to the side of the mounting plate, a rotating shaft rotatably connected to the output end of the seeding motor, a conveying disc fixedly connected to the circumferential surface of the rotating shaft, a seed storage box fixedly connected to the top of the base, the side of the seed storage box penetrating and rotatably connected to the circumferential surface of the rotating shaft, and a seeding tube fixedly penetrating the bottom of the seed storage box, the purpose of which is to automatically sow seeds.

[0012] For example, in at least one embodiment of the present invention, a no-till planter is provided, which further includes: a support frame fixedly connected to the bottom of the base, a rotating shaft rotatably connected inside the support frame, and a corrugated floating pressure roller fixedly connected to the circumferential surface of the rotating shaft, the purpose of which is to compact the soil after sowing and ensure uniform soil coverage.

[0013] The circumferential surface of the rotating shaft is provided with a belt groove, and a belt is provided inside the belt groove. A cleaning shaft is rotatably connected inside the base. A pulley is fixedly passed through the circumferential surface of the cleaning shaft. A stubble cleaning brush is fixedly connected to the circumferential surface of the cleaning shaft. The purpose is to ensure that the serrated stubble removal blade is cleaned and to avoid residue entanglement that may cause work interruption.

[0014] The number of the conveyor tray, seed storage box and sowing tube is set to several, and they are arranged in a linear array along the side of the mounting plate. The stubble cleaning brush is located on the displacement trajectory of the serrated stubble cutter. The purpose is to ensure that the stubble cleaning brush automatically cleans the stubble during the rotation of the serrated stubble cutter.

[0015] The inside of the belt groove is connected to the circumferential surface of the pulley via a belt. The seeding tube is located to the right of the troughing rod. Its purpose is to ensure that when the belt groove rotates through the shaft, the pulley is driven to rotate by the belt.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation of components such as the serrated stubble-cutting blade, the grooving rod, and the electric screw adjustment mechanism of the stubble-cutting and ditching system, when using the seeder, the operator starts the drive motor, the output shaft of the drive motor rotates, driving the rotating disc, and through the conveyor belt, the control shaft one and control shaft two rotate. The control shaft drives the stubble-cutting shaft, which in turn drives the serrated stubble-cutting blade to cultivate the soil; the control shaft two drives the grooving shaft, which drives the grooving rod to groove the soil after stubble cutting. If it is necessary to adjust the grooving depth, the micro motor is started, driving the threaded rod to rotate, pushing the cone block, and then moving the connecting plate to adjust the position of the serrated stubble-cutting blade and the grooving rod to achieve different planting depths. This design achieves the effect of stubble cutting and ditching, improving the flexibility and accuracy of sowing.

[0018] 2. In this utility model, through the coordinated operation of components such as the sowing tube, corrugated floating pressure roller, and stubble cleaning brush in the sowing and compaction system, after the sowing motor is started, its output end drives the rotating shaft to rotate, which in turn drives the conveyor plate to transport the seeds in the seed storage box to the sowing tube. Finally, the corrugated floating pressure roller compacts the soil, ensuring uniform soil coverage. Simultaneously, the rotating shaft drives the belt through a belt groove, thereby rotating the pulley and driving the cleaning shaft and stubble cleaning brush to promptly clean the serrated stubble-removing blade, preventing residue entanglement and maintaining smooth operation. This design achieves the desired sowing and compaction effects, improving sowing efficiency and stability. Attached Figure Description

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a no-till seeder in one embodiment of the present invention, including a base 1, a monitoring terminal display screen 2 on the top of the base 1, a stubble-killing and ditching system 3 on the bottom of the base 1, and a sowing and compaction system 4 on the bottom of the base 1.

[0033] The stubble removal and ditching system 3 includes a fixed plate 31 and a drive motor 32. The bottom of the fixed plate 31 is fixedly connected to the top of the base 1, and the top of the fixed plate 31 is fixedly connected to the circumferential surface of the drive motor 32. The output end of the drive motor 32 is fixedly connected to a rotating disk 33. A conveyor belt 34 is provided on the circumferential surface of the rotating disk 33. A control shaft 35 is rotatably connected inside the base 1. A stubble removal shaft 36 is fixedly connected to the circumferential surface of the control shaft 35. A serrated stubble removal blade 37 is slidably connected through the circumferential surface of the stubble removal shaft 36. A control shaft 38 is rotatably connected inside the base 1. A trenching shaft 39 is fixedly connected to the circumferential surface of the control shaft 38. A trenching rod 310 is slidably connected through the circumferential surface of the trenching shaft 39.

[0034] In some examples, the method also includes: a number of serrated stubble cutters 37 arranged in a circumferential array along the circumference of the stubble cutter axis 36, and a number of grooving rods 310 arranged in a circumferential array along the circumferential array of the grooving axis 39, the purpose of which is to carry out large-area cultivation by means of multiple serrated stubble cutters 37 and grooving axes 39.

[0035] The bottom of the base 1 is provided with an electric screw adjustment mechanism 311. The electric screw adjustment mechanism 311 includes a micro motor 3111. The side of the micro motor 3111 is fixedly connected to the inside of the stubble-cutting shaft 36. The output end of the micro motor 3111 is rotatably connected to a threaded rod 3112. The circumferential surface of the threaded rod 3112 is threadedly connected to a pushing cone block 3113. One end of the serrated stubble-cutting blade 37 and the grooving rod 310 are both fixedly connected to a connecting plate 3114. The circumferential surface of the threaded rod 3112 is fixedly penetrated by a limiting plate 3115, the purpose of which is to achieve different planting depths.

[0036] The number of micro motors 3111, pushing cones 3113 and limiting plates 3115 is set to four, and they are symmetrical to each other along the vertical central axis of the fixed plate 31. The bottom of the connecting plate 3114 is located on the displacement trajectory of the pushing cones 3113. The purpose is to make stable adjustments through multiple pushing cones 3113 to ensure that the movement of the pushing cones 3113 pushes and adjusts the connecting plate 3114.

[0037] A reset spring 3116 is fixedly connected to the side of the connecting plate 3114. The end of the reset spring 3116 away from the side of the connecting plate 3114 is fixedly connected to the inner wall of the stubble-removing shaft 36. The purpose is to ensure that the connecting plate 3114 can automatically reset and reduce manual intervention.

[0038] For example, such as Figures 1-5 As shown, when the seeder is needed, the operator starts the drive motor 32. The output shaft of the drive motor 32 rotates, which drives the rotating disk 33 to rotate. The rotation of the rotating disk 33, via the conveyor belt 34, simultaneously drives the first control shaft 35 and the second control shaft 38 to rotate. The rotation of the first control shaft 35 drives the stubble-cutting shaft 36 to rotate, which in turn drives the serrated stubble-cutting blade 37 to rotate. During the rotation of the serrated stubble-cutting blade 37, the soil is tilled. At the same time, the rotation of the second control shaft 38 drives the trenching shaft 39 to rotate. 9. Rotation drives the trenching rod 310 to rotate. During the rotation of the trenching rod 310, trenches are formed in the soil after stubble removal. When it is necessary to adjust the trenching depth, the micro motor 3111 can be started. The output end of the micro motor 3111 rotates, which drives the threaded rod 3112 to rotate. The rotation of the threaded rod 3112 drives the pusher cone 3113 to move. During the movement of the pusher cone 3113, the connecting plate 3114 is pushed. At this time, the serrated stubble removal blade 37 and the trenching rod 310 are pushed to adjust the length and achieve different planting depths.

[0039] like Figures 1-5As shown, this invention illustrates a no-till seeder in another embodiment of the present invention, which is largely the same as the above-described technical solution. Therefore, only the differences are described. The bottom of the mounting plate 41 is fixedly connected to the top of the base 1. A seeding motor 42 is fixedly connected to the side of the mounting plate 41. A rotating shaft 43 is rotatably connected to the output end of the seeding motor 42. A conveying disc 44 is fixedly connected to the circumferential surface of the rotating shaft 43. A seed storage box 45 is fixedly connected to the top of the base 1. The side of the seed storage box 45 penetrates and is rotatably connected to the circumferential surface of the rotating shaft 43. A seeding tube 46 is fixedly penetrated through the bottom of the seed storage box 45. The purpose of this invention is to automatically sow the seeds.

[0040] In some examples, the base 1 is also fixedly connected to a support frame 47, and a rotating shaft 48 is rotatably connected inside the support frame 47. A corrugated floating pressure roller 49 is fixedly connected to the circumferential surface of the rotating shaft 48. The purpose of this is to compact the soil after sowing and ensure that the soil is covered evenly.

[0041] The circumferential surface of the rotating shaft 43 is provided with a belt groove 410, and a belt 411 is provided inside the belt groove 410. The cleaning shaft 412 is rotatably connected inside the base 1. A pulley 413 is fixedly passed through the circumferential surface of the cleaning shaft 412. A stubble cleaning brush 414 is fixedly connected to the circumferential surface of the cleaning shaft 412. The purpose is to ensure that the serrated stubble-removing knife 37 is cleaned and to avoid residue entanglement that may cause work interruption.

[0042] The number of conveyor trays 44, seed storage boxes 45 and seeding tubes 46 is set to several, and they are arranged in a linear array along the side of the mounting plate 41. The stubble cleaning brush 414 is located on the displacement trajectory of the serrated stubble-killing knife 37. The purpose is to ensure that the serrated stubble-killing knife 37 is automatically cleaned by the stubble cleaning brush 414 during rotation.

[0043] The inside of the belt groove 410 is connected to the circumferential surface of the pulley 413 via the belt 411. The seeding tube 46 is located to the right of the troughing rod 310. Its purpose is to ensure that when the belt groove 410 rotates through the rotating shaft 43, the pulley 413 is driven to rotate by the belt 411.

[0044] For example, such as Figures 1-5As shown, the seeding motor 42 is started simultaneously, and the output end of the seeding motor 42 rotates. The rotation of the output end of the seeding motor 42 drives the rotating shaft 43 to rotate, and the rotating shaft 43 drives the conveying disc 44 to rotate. During the rotation of the conveying disc 44, the seeds inside the seed storage box 45 are conveyed. Then, the seeds are conveyed into the furrow through the seeding tube 46. Finally, the seeds are pushed and compacted by the corrugated floating pressure roller 49 to ensure uniform soil coverage. At the same time, the rotation of the rotating shaft 43 drives the belt 411 to convey through the belt groove 410. The belt 411 conveys through the pulley 413 to rotate, and the rotation of the pulley 413 drives the cleaning shaft 412 to rotate. The rotation of the cleaning shaft 412 drives the stubble cleaning brush 414 to rotate. During the rotation of the stubble cleaning brush 414, the stubble cleaning brush 414 cleans the working serrated stubble cutter 37 to avoid residue entanglement and interruption of operation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
