Precision sowing ensures even seed distribution and reasonable planting density, fully utilizing soil, water, and sunlight resources, reducing seed waste, and lowering production costs. However, traditional sowing devices have many problems in practical applications, making it difficult to meet the demands of modern agriculture for precise and efficient sowing operations.
[0003] For example, Chinese utility model patent application number 201820491376.0 discloses a portable precision grain seeding device. This device, through the coordinated use of a housing, cylinder, horizontal plate, transmission rod, positioning block, rotating plate, transmission plate, oblique hole, transmission column, slide groove, slider, lifting frame, bracket, rollers, seeding device body, and seeding tube, solves the problem of existing seeding devices being inconvenient for users to carry. This portable precision grain seeding device has the advantage of being easy to carry and use, improving the practicality of the seeding device. However, the device still has certain shortcomings.
[0004] When sowing, it is impossible to separate and sieve clumps of seeds. Clumps of seeds may affect the germination rate. Due to the poor air permeability inside the seed clump, some seeds cannot obtain enough oxygen and water and are difficult to germinate normally, resulting in a waste of seed resources.
[0005] Therefore, we proposed a dual-chamber seeding device with vibration seeding to solve the problems mentioned above. Utility Model Content

[0019] The above structural design enables the vibration function of the first and second seeding boxes. This vibration, in conjunction with the movement of the agitator claw, further enhances the treatment effect on clustered seeds, improves the seeding quality, and ensures better seed dispersion and selection.
[0020] Preferably, the upper surface of both the first and second seeding boxes is provided with a door, and the filter screen is detachably connected to the first and second seeding boxes, with the filter screen having a spliced structure design.

[0034] Please see Figures 1-7This utility model provides a technical solution: a dual-chamber seeding device for vibration seeding, comprising a support plate 1, a guide groove 2, a support bar 3, a connecting plate 4, a first seeding box 5, a second seeding box 6, an elastic tube 7, a fixing tube 8, a connecting frame 9, a first servo motor 10, a first reciprocating screw 11, a second reciprocating screw 12, a connecting belt 13, a slider 14, a toggle claw 15, a connecting block 16, a guide rod 17, a vertical plate 18, a seed storage box 19, a mounting plate 20, a second servo motor 21, a connecting plate 22, a first hinge assembly 23, a second hinge assembly 24, a reinforcing connecting bar 25, a filter screen 26, and a seed divider 27. The first seeding box 5 and the second seeding box 6 are respectively arranged on the front and rear sides of the upper surface of the support plate 1. A guide groove 2 is provided on the surface, and a support bar 3 is provided above the guide groove 2. A connecting plate 4 is installed above the support bar 3. The connecting plate 4 is connected to the first seeding box 5 and the second seeding box 6. A limit rod is installed inside the guide groove 2, and the limit rod passes through the support bars 3 on both sides. The support bars 3 are slidably connected to the limit rod. When the second servo motor 21 is started, the output shaft of the second servo motor 21 drives the connecting plate 22 to rotate. When the connecting plate 22 rotates, the first hinge assembly 23 will perform a circular motion. The first hinge assembly 23 is connected to the second hinge assembly 24 through the reinforcing connecting bar 25. The second hinge assembly 24 is installed on the right support bar 3, which allows the support bar 3 to slide back and forth along the limit rod in the guide groove 2. The support bar 3 is connected to the first seeding box 6 through the connecting plate 4. Seed box 5 is connected to the second seeding box 6, thereby causing the first seeding box 5 and the second seeding box 6 to reciprocate.

During the vibration of the first seed box 5 and the second seed box 6, the agitator 15 continuously shuttles through the seeds, breaking up the clumps of seeds and screening them through the filter screen 26 to select the seeds that meet the sowing requirements.
[0035] The first seeding box 5 and the second seeding box 6 are respectively equipped with a first reciprocating lead screw 11 and a second reciprocating lead screw 12. A slider 14 is installed on both the first reciprocating lead screw 11 and the second reciprocating lead screw 12. A pawl 15 is installed on each slider 14.

The first hinge assembly 23 and the second hinge assembly 24 are connected by a reinforcing connecting strip 25. The second servo motor 21 can drive the connecting plate 22 to rotate via its output shaft, and the connecting plate 22 drives the second servo motor 24 to rotate. A hinge assembly 23 rotates, and the first hinge assembly 23 drives the support bar 3 to move through the reinforcing connecting bar 25 and the second hinge assembly 24. The second hinge assembly 24 is installed on the right side of the right support bar 3. The first seeding box 5 and the second seeding box 6 are both equipped with filter screens 26. The upper surface of the first seeding box 5 and the second seeding box 6 are both provided with box doors. The filter screen 26 is detachably connected to the first seeding box 5 and the second seeding box 6. The filter screen 26 has a spliced structure design. The filter screen 26 can filter the seeds on the first seeding box 5 and the second seeding box 6 to prevent clumps of seeds from falling.
[0037] Working principle: When using this vibrating seeding dual-chamber seeding device, firstly, the second servo motor 21 is started. The output shaft of the second servo motor 21 drives the connecting plate 22 to rotate. When the connecting plate 22 rotates, the first hinge assembly 23 will perform circular motion. The first hinge assembly 23 is connected to the second hinge assembly 24 through the reinforcing connecting strip 25. The second hinge assembly 24 is installed on the right support strip 3, which causes the support strip 3 to slide back and forth along the limiting rod in the guide groove 2. The support strip 3 is connected to the first seeding box 5 and the second seeding box 6 through the connecting plate 4, thereby driving the first seeding box 5 and the second seeding box 6 to perform reciprocating vibration, causing them to vibrate. At the same time, the first servo motor 10 is started. The first servo motor 10 drives the first reciprocating screw 11 to rotate. The first reciprocating screw 11 drives the second reciprocating screw 12 to rotate via the connecting belt 13. The sliders 14 on the first and second reciprocating screws 11 and 12 then reciprocate linearly under the constraint of the guide rod 17. The actuating claws 15 on the sliders 14 move accordingly. During the vibration of the first and second seeding boxes 5 and 6, the actuating claws 15 continuously move through the seeds, breaking up clumps and sieving them through the filter screen 26 to select seeds that meet the sowing requirements. The sieving seeds then enter the seed separator 27 through the elastic tube 7 and the fixed tube 8. The miniature drive motor on the seed separator 27 drives the seed-separating components to rotate, causing the grooves on the seed separator 27 to load seeds sequentially, evenly sowing the seeds onto the soil, thus completing a series of operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
