Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeders, and more specifically, to a seeder for agricultural production. Background Technology
[0002] Seeders are a type of planting machinery whose core function is to sow crop seeds, including both common seeds and pelleted coated seeds. Depending on the crop they are used for, seeders can be further divided into various types, often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and pasture spreaders.
[0003] Existing seeders still have the following problems:
[0004] 1. Existing seeders, after sowing, often fail to push the soil from both sides of the furrow towards the center, easily resulting in incomplete seed burial. This leads to seeds being exposed to sunlight and losing their viability. Most current seeders lack an effective backfilling mechanism after furrowing, failing to promptly and evenly push back the soil turned over to the sides to cover the sown seeds. This results in some seeds not being fully buried and remaining exposed on the surface. Exposed seeds are highly susceptible to sun exposure and dehydration, bird pecking, or adverse weather conditions, severely diminishing their germination activity and directly impacting the seedling emergence rate.
[0005] 2. Existing seeders generally lack pre-screening capabilities for seeds. During sowing, plump seeds are mixed with shriveled, damaged, or excessively small inferior seeds and are directly sown into the soil without sorting. These inferior seeds themselves have low germination rates and will not emerge properly even after sowing. This not only wastes valuable seed resources but also directly leads to sparse and uneven emergence in the field, significantly reducing the overall sowing effect and crop yield potential.
[0006] 3. The feed hopper design of seeders is usually quite simple, serving only as a storage container for seeds. When a large number of seeds are poured into the hopper, they easily accumulate at the bottom, especially above the narrow discharge port. The mutual compression and friction between the seeds increase flow resistance, making them prone to clogging at the critical discharge port. Once a blockage occurs, the seeding process is interrupted, requiring manual intervention to clear the blockage, which seriously affects the continuity and efficiency of the seeding operation.
[0007] Therefore, there is an urgent need for a seeder for agricultural production. Utility Model Content

[0014] The present invention is further configured such that the connecting shell is fixedly connected to a first fixing ring, the fixing shell is fixedly connected to a second fixing ring, the center of the first fixing ring and the center of the second fixing ring are on the same vertical line as the center of the fixing shell, a guide tube is fixedly connected to the lower side of the second fixing ring, the guide tube communicates with the seeding shell, and the fixing shell is provided with a discharge through hole.
[0015] The present invention is further configured such that an annular fixing frame is fixedly connected to the inner wall of the connecting ring, and a filter element is fixedly connected to the annular fixing frame, with the upper and lower sides of the filter element contacting the first fixing ring and the second fixing ring, respectively.
[0016] The present invention is further configured such that the center of the annular fixing frame and the center of the fixing shell are not on the same vertical line.
[0017] The present invention is further configured such that the connecting ring is fixedly connected to a toothed ring, the fixed shell is fixedly connected to a motor, the motor is fixedly connected to a gear, and the gear meshes with the toothed ring.

[0019] (III) Beneficial Effects
[0020] Compared with the prior art, this utility model provides a seeder for agricultural production, which has the following beneficial effects:
[0021] 1. This utility model utilizes a specially designed double-conical roller. During rolling, the gap structure effectively pushes the soil from both sides of the furrow opened by the sowing device towards the center, covering the sown seeds. This dynamic soil covering method ensures that the seeds are fully buried by the soil, avoiding the risk of seed loss or being pecked at, which is common in traditional methods, and significantly improving the germination rate.
[0022] 2. This invention utilizes a motor to drive an eccentrically mounted filter element to continuously vibrate, efficiently screening the incoming seeds. Plump seeds pass smoothly through the screen and fall into the guide tube for sowing, while shriveled, damaged, or inferior seeds are effectively separated and discharged through the discharge holes of the fixed shell. This automatic screening process significantly improves the overall quality of the sown seeds, ensuring uniform germination and crop potential.
[0023] 3. This utility model uses a second motor to drive the feeding shaft to rotate at a uniform speed. The groove on the shaft precisely and quantitatively receives the seeds in the feeding box and releases them in an orderly manner when it rotates to the bottom. This intermittent, quantitative feeding method effectively avoids the problem of clogging caused by excessive seed accumulation at the seeding shell inlet or the groove of the rotating part, ensuring the continuity and stability of the sowing operation.

[0034] Please see Figure 3The seed screening structure includes a fixed shell 11, a connecting ring 12 rotatably connected to the fixed shell 11, and a connecting shell 13 rotatably connected to the connecting ring 12. A connecting piece is fixed between the connecting shell 13 and the fixed shell 11. A first fixing ring 14 is fixedly connected to the connecting shell 13, and a second fixing ring 15 is fixedly connected to the fixed shell 11. The centers of the first fixing ring 14 and the second fixing ring 15 are on the same vertical line as the center of the fixed shell 11. A guide tube 16 is fixedly connected to the lower side of the second fixing ring 15, and the guide tube 16 is connected to the seeding shell 2. The fixed housing 11 is provided with a discharge through hole; the inner wall of the connecting ring 12 is fixedly connected to an annular fixing frame 17, and the annular fixing frame 17 is fixedly connected to a filter element 18. The upper and lower sides of the filter element 18 are in contact with the first fixing ring 14 and the second fixing ring 15, respectively; the center of the annular fixing frame 17 and the center of the fixed housing 11 are not on the same vertical line; the connecting ring 12 is fixedly connected to a toothed ring 19, the fixed housing 11 is fixedly connected to a motor 20, the motor 20 is fixedly connected to a gear 21, and the gear 21 meshes with the toothed ring 19.
[0035] Please see Figure 2 and Figure 5 The material control structure includes a support shell 22, which is fixedly connected to the connecting shell 13. The support shell 22 is rotatably connected to a feeding shaft 23, which is provided with a groove 24. The support shell 22 is fixedly connected to a motor 25, whose output shaft is fixedly connected to the feeding shaft 23. A feeding box 26 is fixedly connected to the upper side of the support shell 22.
[0036] The working principle of this utility model is as follows: When using this seeder for sowing, the seeds are placed in the feeding box 26, and then the frame 1 is dragged to move in a straight line. The frame 1 drives the roller 7 to rotate, which in turn causes the pulley 8 to drive the pulley 9 to rotate. The transmission ratio of pulley 8 and pulley 9 is changed according to the actual situation. The pulley 9 drives the connecting shaft 4 to rotate, and the connecting shaft 4 drives the rotating component 3 to rotate circumferentially within the sowing shell 2. At the same time, the sowing component 10 digs a trench in the ground. During the above process, motors 20 and 25 are started, and the seeds fall into the groove 24 of the feeding shaft 23. Motor 25 drives the feeding shaft 23 to rotate. The second groove 24 drives the seeds to rotate. When the second groove 24 rotates to the lower side, the seeds fall downwards. The first motor 20 drives the gear ring 19 to rotate through the gear 21. The gear ring 19 drives the connecting ring 12 to rotate circumferentially. Since the annular fixing frame 17 and the filter element 18 are eccentrically installed with the connecting ring 12, the filter element 18 shakes inside the fixing shell 11 and the connecting shell 13. When the seeds fall into the filter element 18, the filter element 18 drives the seeds to shake circumferentially, thereby filtering the shriveled seeds. The good seeds accumulate in the guide tube 16, and the shriveled seeds enter between the guide tube 16 and the fixing shell 11 and are discharged from the discharge through hole of the fixing shell 11.
[0037] The seeds fall into the groove 5. The rotating part 3 drives the seeds to rotate circumferentially. When the seeds rotate to the lower side of the sowing shell 2, they fall into the sowing part 10 and from the lower end of the sowing part 10 into the ground trench. The roller 7 rolls forward and pushes the soil on both sides of the trench towards the middle, thus completing the burying of the seeds. As the frame 1 moves, continuous sowing is achieved.
[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
