Description
Technical Field
[0001] This application relates to the field of seeders, and in particular to a seeder with a cleaning structure. Background Technology
[0002] Sowing is one of the crop cultivation measures. It is the operation of sowing materials in a certain quantity and method, at the appropriate time and depth in the soil. Whether the sowing is appropriate or not directly affects the growth, development and yield of crops. In order to improve the quality of sowing, in addition to fine land preparation, seed treatment and preparation of labor, animal power and sowing machinery are also necessary before sowing.
[0003] In existing technologies, seed planters generally suffer from structural design deficiencies, with a key flaw being the lack of an integrated, effective soil-digging and cleaning mechanism. This results in straw, weeds, or compacted soil often remaining in the planting furrows, causing some seeds to fall directly onto hard or foreign surfaces. Because these seeds cannot fully contact the soil, their water absorption and root establishment are severely affected, ultimately leading to a significant reduction in germination rate and poor seedling uniformity, directly restricting crop yield and agricultural economic benefits. Utility Model Content

This results in straw, weeds, or compacted soil often remaining in the seed furrows, causing some seeds to fall directly onto hard or foreign surfaces. Because these seeds cannot fully contact the soil, their water absorption and root fixation are severely affected, ultimately leading to a significantly reduced germination rate and poor seedling uniformity, directly restricting crop yield and agricultural economic benefits.
[0005] This application provides a seeder with a cleaning structure, which adopts the following technical solution:
[0006] A seeder with a cleaning structure includes a seed box, an outer frame, a flared support, a rotating arm, a seeding assembly, and a soil cleaning assembly. The seed box is disposed above the outer frame, the flared support is fixedly connected to the inner side of the outer frame, the rotating arm is rotatably connected to the inner side of the flared support, the seeding assembly is installed at the bottom of the seed box, and the soil cleaning assembly is installed on the outer side of the rotating arm.

[0008] In one feasible technical solution of this application, the soil covering and cleaning assembly includes a sliding chuck, a transverse abutment, an arc-shaped groove, loosening teeth, a protrusion, a compression spring, and a soil covering and cleaning wheel. The sliding chuck is sleeved on both ends of the soil covering and cleaning wheel. The transverse abutment is fixedly connected to the inner side of the sliding chuck, and the surface of the transverse abutment abuts against the surface of the loosening teeth. The arc-shaped groove is formed on the inner side of the soil covering and cleaning wheel. The surface of the loosening teeth is rotatably connected to the inner side of the soil covering and cleaning wheel located in the arc-shaped groove. The protrusion is fixedly connected to the outer side of the transverse abutment. The two ends of the compression spring are respectively fixedly connected to the opposite side surfaces of the loosening teeth and the protrusion.

[0013] This device, through the synergistic action of a soil-covering and cleaning wheel and loosening teeth, actively rotates before sowing, effectively loosening compacted soil and clearing away straw, weeds, and other foreign objects from the seed furrow, preparing a clean and soft ideal seedbed for the seeds. This fundamentally solves the problem of seed staking, ensuring that the seeds can fully contact the soil, thereby significantly improving the effective soil coverage rate and uniformity. The loosening teeth, under the action of a compression spring, adapt to the terrain, efficiently completing the soil-digging and cleaning tasks, ensuring that the seeds always land in the optimal position. Furthermore, by pushing the cylinder and sliding chuck structure, the downward pressure and penetration depth of the soil-covering and cleaning wheel can be precisely adjusted to adapt to different soil conditions, ensuring operational quality under various working conditions. Under the continuous action of the compression spring, the loosening teeth can always maintain effective scraping and cleaning pressure on the bottom of the furrow. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] This application discloses a seeder with a cleaning structure. (Refer to...) Figures 1 to 4 The seeder with a cleaning structure includes a seed box 1, an outer frame 2, a flared support 3, a rotating support arm 4, a seeding component 5, and a soil cleaning component 6. The seed box 1 is located above the outer frame 2. The flared support 3 is fixedly connected to the inner side of the outer frame 2. The rotating support arm 4 is rotatably connected to the inner side of the flared support 3. The seeding component 5 is installed at the bottom of the seed box 1, and the soil cleaning component 6 is installed on the outer side of the rotating support arm 4.
[0030] The seeding assembly 5 includes a straight connecting pipe 51, a feed pump 52, a folded hose 53, a positioning plate frame 54, and a discharge pipe 55. The straight connecting pipe 51 is fixedly connected to the bottom of the seeding box 1. The feed pump 52 is installed on the outside of the straight connecting pipe 51. The two sides of the folded hose 53 are respectively connected to the inside of the straight connecting pipe 51 and the positioning plate frame 54. The positioning plate frame 54 is slidably snapped into the inside of the outer frame 2. The discharge pipe 55 is fixedly connected to the outside of the output end of the folded hose 53.
[0031] The soil cleaning assembly 6 includes a sliding chuck 61, a transverse abutment 62, an arc-shaped groove 63, loosening teeth 64, a protrusion 65, a compression spring 66, and a soil cleaning wheel 67. The sliding chuck 61 is sleeved on both ends of the soil cleaning wheel 67. The transverse abutment 62 is fixedly connected to the inner side of the sliding chuck 61, and the surface of the transverse abutment 62 abuts against the surface of the loosening teeth 64. The arc-shaped groove 63 is opened on the inner side of the soil cleaning wheel 67. The surface of the loosening teeth 64 is rotatably connected to the inner side of the soil cleaning wheel 67 located in the arc-shaped groove 63. The protrusion 65 is fixedly connected to the outer side of the transverse abutment 62. The two ends of the compression spring 66 are fixedly connected to the opposite side surfaces of the loosening teeth 64 and the protrusion 65, respectively. The soil cleaning wheel 67 is rotatably connected to the inner side of the rotating support arm 4.
[0032] The DC motor 12 drives the rotating support arm 4 to lower as a whole, bringing the soil covering and cleaning assembly 6 into contact with the ground. Subsequently, the stepper motor 11 drives the soil covering and cleaning wheel 67 to rotate at high speed. Under the continuous pressure provided by the compression spring 66, the loosening teeth 64 installed on the cleaning wheel effectively loosen the compacted soil and remove straw, weeds and other residues from the trench.
[0033] The outer side of the rotating support arm 4 is also provided with a push cylinder 7, a push rod 8, a linear shaft 9 and a limiting plate 10. The push cylinder 7 is installed on the outer side of the rotating support arm 4. The push rod 8 is fixedly connected to the outer side of the output end of the push cylinder 7. The limiting plate 10 is fixedly connected to the outer side of the push rod 8. The linear shaft 9 passes through the interior of the limiting plate 10 and is fixedly connected to the surface of the rotating support arm 4.
[0034] While the seedbed is prepared, the sowing assembly 5 operates simultaneously. Seeds flow from the sowing box 1, are precisely metered by the feed pump 52 via the direct connection pipe 51, and then guided by the folded flexible hose 53 before being accurately placed into the cleaned seed furrows through the discharge pipe 55. The sowing depth is uniformly adjusted and controlled by the sliding of the positioning plate frame 54 on the outer frame 2, ensuring the consistency of the sowing operation.
[0035] A stepper motor 11 is also provided on one side of the rotating support arm 4. The motor shaft of the stepper motor 11 is fixedly connected to one end of the soil cleaning wheel 67 through a coupling.
[0036] A DC motor 12 and a rotating shaft 13 are also provided on the side of the flared bracket 3 near the rotating arm 4. The output end of the DC motor 12 is fixedly connected to one end of the rotating shaft 13, and the outer wall of the rotating shaft 13 is welded to one side of the rotating arm 4.
[0037] The entire machine's operation is precisely controlled by an electric drive system. The DC motor 12 is responsible for lifting and lowering the seeding assembly 5, while the push cylinder 7 precisely controls the downward pressure of the soil-covering cleaning wheel 67 on the ground by pushing the sliding chuck 61.
[0038] The operation of the seeder with a cleaning structure according to this application embodiment is roughly as follows:
[0039] First, the DC motor 12 drives the rotating shaft 13, causing the welded rotating support arm 4 to rotate as a whole, thereby lowering the sowing component 5 and the soil covering and cleaning component 6 installed on it to the working position. Then, the push cylinder 7 starts working, pushing the push rod 8 and the limiting plate 10 to move along the linear axis 9, transmitting pressure to the sliding chuck 61, ultimately bringing the soil covering and cleaning component 6 into contact with the ground. Simultaneously, the stepper motor 11 starts, directly driving the soil covering and cleaning wheel 67 to rotate at high speed. During rotation, the loosening teeth 64, under the continuous pressure of the compression spring 66, with one end of the spring acting on the protrusion 65 and the other end pressing against the loosening teeth 64, loosen and sweep the soil. The transverse abutment 62 at its end acts as a limit, ensuring the stability of the cleaning action. While the seedbed cleaning is completed, the sowing component 5 begins to work. Seeds are precisely delivered from the seeding box 1 via a direct connection pipe 51 and a feed pump 52, then through a flexible, extendable folding hose 53, and finally discharged from the discharge pipe 55 into the cleaned seed furrow. The entire seeding depth is adjusted and stabilized by the sliding of the positioning plate frame 54 on the inner side of the outer frame 2.
[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
