Description
Technical Field
[0001] This utility model relates to the field of agricultural sowing, and in particular to a seeder for agricultural production. Background Technology
[0002] In the process of modern agricultural production, the sowing stage is a crucial initial stage in crop planting, and its quality and efficiency have a profound impact on the yield and quality of crops.
[0003] Existing seeders have significant limitations in terms of applicability. In areas with complex terrain such as mountains and hills, ordinary seeders struggle to navigate and operate smoothly due to the significant topographical variations and irregular plots. Furthermore, the small private plots commonly found in rural areas of my country are not suitable for existing seeders and other mechanized operations, typically requiring manual labor. Based on these considerations, we propose a seeder for agricultural production. Utility Model Content
[0004] To address the technical problem of insufficient adaptability of seeding machinery, this utility model provides a seeder for agricultural production.
[0005] This utility model is achieved by the following technical solution: an agricultural seeder, including a frame, a seed box is fixedly connected to the bottom surface of the frame by bolts, handles are fixedly connected to the top of the frame extending to both sides, a movable collar that can slide up and down along the frame is fitted on the surface of the frame, a foot pedal is fixedly connected to one side of the surface of the movable collar, and a movable frame is fixedly connected to the other side of the surface of the movable collar; the foot pedal is a long strip-shaped pedal with anti-slip texture on its top surface, and the foot pedal, the movable collar, and the movable frame are integrally fixed.
[0006] A return spring post is fixedly connected to the bottom end of the movable collar, and a fixed collar is connected to the bottom end of the return spring post. The fixed collar is fixedly sleeved on the surface of the frame. A lower pressure bracket is rotatably connected to the outside of the movable frame. A connecting block is rotatably connected to the bottom end of the lower pressure bracket. The connecting block is connected to the edge of the rotating disk. A rotating rod is fixedly connected to the center of the rotating disk. A baffle plate is connected to the end of the rotating rod away from the rotating disk. The middle part of the rotating rod rotates through a baffle plate extending downward from the bottom of the seed box. The baffle plate supports the rotating rod.
[0007] The operator grips the handles extending from the top sides of the frame and starts the sowing operation by pressing the foot pedal. The foot pedal is integrated with the moving collar and moving frame. When the foot pedal is pressed, the moving collar slides downwards along the frame, causing the moving frame to move downwards as well. The pressure bracket fixedly connected to the outside of the moving frame also descends. The connecting block at the bottom of the pressure bracket is connected to the edge of the rotating disk. The descent of the pressure bracket causes the rotating disk to rotate around its axis. The rotating rod fixedly connected to the axis of the rotating disk rotates with the rotating disk. The middle part of the rotating rod rotates through a baffle extending downwards from the bottom of the seed box. The baffle supports the rotating rod and ensures its stable rotation.
[0008] When the operator releases the pedal, the moving collar returns to its original position under the action of the return spring. One end of the return spring is connected to the moving collar, and the other end is connected to the fixed collar, which is fixedly fitted onto the surface of the frame. The upward movement of the moving collar causes the moving frame, the lower support, and other components to rise synchronously, the rotating disk rotates in the opposite direction, and the baffle plate closes the discharge port at the bottom of the seed box again, completing one sowing cycle.
[0009] As a further optimization of this utility model, the foot pedal is a long strip-shaped pedal with anti-slip texture on its top surface, which makes it convenient for operators to step on, increases the friction between the sole of the foot and the pedal, avoids slipping during operation, and ensures the smooth progress of the sowing operation.
[0010] As a further optimization of this utility model, the seed box is funnel-shaped with an open top for easy seed loading and unloading. A rectangular discharge port is provided at the bottom of the seed box. The funnel-shaped design facilitates the concentrated sliding of seeds to the discharge port, and the sowing amount is controlled in conjunction with the baffle plate.
[0011] As a further optimization of this invention, the seeds are loaded into a funnel-shaped seed box. Since the top of the seed box is open, operation is convenient. At this time, the baffle plate is in the closed state of the rectangular discharge port at the bottom of the seed box, preventing premature leakage of seeds.
[0012] As a further optimization of this utility model, the barrier plate is a semi-cylindrical structure with a semi-circular cross-section. The flat surface of the semi-cylindrical shell of the barrier plate faces the bottom of the seed box, thus blocking the seeds in the seed box.
[0013] As a further optimization of this utility model, the rotating rod swings to drive the connected baffle plate to move. The baffle plate has a semi-cylindrical structure, with its flat surface facing the bottom of the seed box. When the rotating rod drives the baffle plate to rotate to a certain angle, the baffle plate will open the discharge port at the bottom of the seed box, and the seeds will fall through the discharge port under the action of gravity, realizing the sowing operation.
[0014] As a further optimization of this utility model, a support column is welded to the bottom of the frame, and the bottom end of the support column is fixedly mounted on a support plate, which is rectangular and rests on the ground. During the sowing process, the operator drives the seeder forward, and as the seeder moves, the above-mentioned stepping and resetting actions are repeated continuously to achieve continuous sowing operations.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model incorporates a handle, a foot pedal, a moving collar, and a return spring. The operator grips the handle and presses the foot pedal to start sowing; releasing the pedal allows the plant to automatically return to its original position under the action of the return spring. The entire operation is simple and labor-saving. Compared to traditional sowing methods, this significantly reduces labor intensity. Even in small plots of land, a single person can easily complete the sowing, improving efficiency.
[0017] 2. This utility model features a support column welded to the bottom of the frame, with a rectangular support plate installed at the bottom of the support column. This structure allows the seeder to be stably placed and operated in complex terrains such as mountains, hills, and small plots of land. Compared to ordinary seeders, it can adapt to different terrain undulations and plot shapes, effectively solving the problem of traditional seeders having difficulty operating in special terrains and expanding the scope of application of the seeder.
[0018] 3. This utility model features a funnel-shaped seed box with a semi-cylindrical baffle plate. Seeds slide in a concentrated manner to the discharge port, and the baffle plate, driven by a rotating rod, precisely controls the opening and closing of the discharge port. When the baffle plate is closed, it prevents premature seed leakage; when open, the seeds fall evenly, avoiding waste. It allows for control of the sowing rate according to actual needs, ensuring uniform sowing and providing a guarantee for the subsequent healthy growth of crops, thus contributing to improved crop yield and quality.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example 1:
[0026] Please combine Figures 1-3 This embodiment proposes a seeder for agricultural production, including a frame 1. A seed box 13 is bolted to the bottom surface of the frame 1. The seed box 13 is funnel-shaped with an open top for easy loading and unloading of seeds. A rectangular discharge port is provided at the bottom of the seed box 13, and a hinged, rotatable baffle plate 12 is attached to the discharge port. Before use, seeds are loaded into the funnel-shaped seed box 13. Because the top of the seed box 13 is open, operation is convenient. At this time, the baffle plate 12 is in the closed state of the rectangular discharge port at the bottom of the seed box 13 to prevent premature seed leakage.
[0027] The top of the frame 1 extends to both sides and is fixedly connected to the handles 2. The surface of the frame 1 is fitted with a movable collar 3 that can slide up and down along the frame 1. A foot pedal 4 is fixedly connected to one side of the surface of the movable collar 3, and a movable frame 5 is fixedly connected to the other side of the surface of the movable collar 3. The foot pedal 4 is a long strip-shaped pedal with anti-slip texture on its top surface. The foot pedal 4 is fixedly integrated with the movable collar 3 and the movable frame 5.
[0028] The bottom end of the movable collar 3 is fixedly connected to a return spring post 6, which is sleeved on the frame 1. The bottom end of the return spring post 6 is connected to a fixed collar 7, which is fixedly sleeved on the surface of the frame 1.
[0029] A downward pressure bracket 8 is rotatably connected to the outer side of the movable frame 5. A connecting block 9 is rotatably connected to the bottom end of the downward pressure bracket 8. The connecting block 9 is connected to the edge of the rotating disk 10. A rotating rod 11 is fixedly connected to the center of the rotating disk 10. A baffle plate 12 is connected to the end of the rotating rod 11 away from the rotating disk 10. The middle part of the rotating rod 11 rotates through the baffle plate extending downward from the bottom end of the seed box 13. The baffle plate supports the rotating rod 11.
[0030] The specific technical solution involves the operator holding the handles 2 extending from the top sides of the frame 1 and starting the sowing operation by stepping on the pedal 4. The pedal 4 is integrated and fixed with the moving collar 3 and the moving frame 5. When the pedal 4 is stepped on, the moving collar 3 will slide downward along the frame 1.
[0031] The sliding collar 3 slides downwards, causing the moving frame 5 to move downwards as well. The pressing bracket 8, fixedly connected to the outside of the moving frame 5, also descends accordingly. The connecting block 9 at the bottom of the pressing bracket 8 is connected to the edge of the rotating disk 10. The descent of the pressing bracket 8 causes the rotating disk 10 to rotate around its axis. The rotating rod 11, fixedly connected to the axis of the rotating disk 10, rotates with the rotating disk 10. The middle part of the rotating rod 11 rotates through the baffle extending downwards from the bottom of the seed box 13. The baffle supports the rotating rod 11, ensuring its stable rotation.
[0032] It should be noted that the barrier plate 12 has a semi-cylindrical structure with a semi-circular cross-section. The flat surface of the semi-cylindrical shell of the barrier plate 12 faces the bottom of the seed box 13, thus blocking the seeds in the seed box 13.
[0033] More specifically, the rotating rod 11 swings, causing the connected baffle plate 12 to move. The baffle plate 12 has a semi-cylindrical structure, with its flat surface facing the bottom of the seed box 13. When the rotating rod 11 drives the baffle plate 12 to rotate to a certain angle, the baffle plate 12 will open the discharge port at the bottom of the seed box 13, and the seeds will fall through the discharge port under the action of gravity, realizing the sowing operation.
[0034] The technical solution for the reset process is as follows: when the operator releases the pedal 4, the moving collar 3 resets upward under the action of the reset spring column 6. One end of the reset spring column 6 is connected to the moving collar 3, and the other end is connected to the fixed collar 7, which is fixedly fitted onto the surface of the frame 1. The upward movement of the moving collar 3 causes the moving frame 5, the lowering support 8, and other components to rise synchronously, the rotating disk 10 rotates in the opposite direction, and the baffle plate 12 closes the discharge port at the bottom of the seed box 13 again, completing one sowing cycle.
[0035] A support column 14 is welded to the bottom of the frame 1. The bottom of the support column 14 is fixedly installed on a support plate 15, which is a rectangular plate supporting the ground. During the sowing process, the operator drives the seeder forward. As the seeder moves, the operator repeatedly performs the aforementioned stepping and resetting actions to achieve continuous sowing operations.
[0036] The working principle of this agricultural seeder is based on the coordinated operation of its various components, as detailed below:
[0037] Preparation phase:
[0038] Before use, the seeds are first loaded into the funnel-shaped seed box 13. Since the top of the seed box 13 is open, operation is convenient. At this time, the baffle plate 12 is in the closed position of the rectangular discharge port at the bottom of the seed box 13 to prevent premature leakage of seeds.
[0039] Sowing start-up operation:
[0040] The operator holds the handles 2 extending from the top of the frame 1 on both sides and starts the seeding operation by stepping on the pedal 4. The pedal 4 is fixed together with the moving collar 3 and the moving frame 5. When the pedal 4 is stepped on, the moving collar 3 will slide down along the frame 1.
[0041] The pressing and rotating parts are linked:
[0042] The sliding collar 3 slides downwards, causing the moving frame 5 to move downwards as well. The pressing bracket 8, fixedly connected to the outside of the moving frame 5, also descends accordingly. The connecting block 9 at the bottom of the pressing bracket 8 is connected to the edge of the rotating disk 10. The descent of the pressing bracket 8 causes the rotating disk 10 to rotate around its axis. The rotating rod 11, fixedly connected to the axis of the rotating disk 10, rotates with the rotating disk 10. The middle part of the rotating rod 11 rotates through the baffle extending downwards from the bottom of the seed box 13. The baffle supports the rotating rod 11, ensuring its stable rotation.
[0043] Barrier plate action and seeding:
[0044] The rotating rod 11 swings, causing the connected baffle plate 12 to move. The baffle plate 12 has a semi-cylindrical structure, with its flat surface facing the bottom of the seed box 13. When the rotating rod 11 drives the baffle plate 12 to rotate to a certain angle, the baffle plate 12 will open the discharge port at the bottom of the seed box 13, and the seeds will fall through the discharge port under the action of gravity, realizing the sowing operation.
[0045] Reset process:
[0046] When the operator releases pedal 4, the moving collar 3 returns to its original position under the action of the return spring column 6. One end of the return spring column 6 is connected to the moving collar 3, and the other end is connected to the fixed collar 7, which is fixedly fitted onto the surface of the frame 1. The upward movement of the moving collar 3 causes the moving frame 5, the lower support bracket 8, and other components to rise synchronously, the rotating disk 10 rotates in the opposite direction, and the baffle plate 12 closes the discharge port at the bottom of the seed box 13 again, completing one sowing cycle.
[0047] Overall movement and continuous seeding:
[0048] The support column 14 welded to the bottom of the frame 1 supports the support plate 15 on the ground. During the sowing process, the operator drives the seeder forward, and as the seeder moves, the above-mentioned stepping and resetting actions are repeated continuously to achieve continuous sowing operations.
[0049] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
