Description

Technical Field

[0001] This utility model relates to a seeder device, specifically a dual-mode seed box for a seeder, belonging to the technical field of seeder equipment. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop type, such as grain strip seeder, corn hill seeder, cotton seeder, and pasture broadcaster.

[0003] However, most existing seeders suffer from various problems. For example, while the plow-type seeder disclosed in CN2552309Y can adjust the plant spacing to adapt to different crops and is highly adaptable, the seed boxes in this technology and most current seeders are designed for a single sowing mode, resulting in poor adaptability. Traditional seed boxes only support a single sowing method (such as row sowing or spot sowing) or a single seed size, requiring frequent replacement of the seed box or internal structure, which is time-consuming and labor-intensive. Switching is complex, and some adjustable seed boxes rely on external tools to disassemble and adjust components (such as replacing the seed metering disc and seed guide tube), which is cumbersome and easily damages parts, increasing the risk of seed mixing. Multi-chamber seed boxes lack effective isolation structures, making seeds prone to mixing due to vibration during sowing, affecting sowing accuracy. Maintenance is inconvenient, cleaning the seed box is difficult, and residual seeds are prone to mold and clogging the seed metering port. Therefore, there is an urgent need for an integrated seed box with a simple structure, quick mode switching, and support for multiple sowing needs. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a dual-mode seed box for a seeder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-mode seed box for a seeder includes a frame, wheels, a seed storage mechanism, and a seeding mechanism. The wheels are rotatably connected to both sides of the frame. The seed storage mechanism and the seeding mechanism are both mounted on the frame and are arranged side by side.

[0007] The seed storage mechanism includes a first support frame, a seed storage box, a partition, a discharge port, and a limiting unit. The first support frame is fixed on the machine frame and has a slot at the bottom of the machine frame. The seed storage box is snapped into the slot. A strip-shaped groove is provided at the center of the inner wall of the seed storage box. The partition is detachably snapped into the strip-shaped groove. The discharge port is provided through both sides of the bottom of the seed storage box.

[0008] The sowing mechanism includes a second support frame, a transmission rod, a drive unit, and an adjustment unit. The second support frame is fixed on the machine frame and located on one side of the first support frame. The transmission rod is rotatably connected to the second support frame.

[0009] As a further embodiment of this utility model: the limiting unit includes a receiving hopper and a discharging plate. The receiving hopper has a T-shaped structure and is fixed on the first support frame and located at the bottom of the seed storage box. A through groove is provided through the first support frame. The discharging plate is slidably engaged in the through groove and is located between the seed storage box and the receiving hopper. Two through holes are provided on the discharging plate, and the through holes and the discharge port are located in the same plane.

[0010] As a further embodiment of this utility model: the sowing mechanism further includes a serrated seed metering wheel, a negative pressure seed metering disc, and a guide pipe. The serrated seed metering wheel and the negative pressure seed metering disc are coaxially rotatably connected to the transmission rod and arranged in parallel. The negative pressure seed metering disc has multiple negative pressure adsorption holes on its surface and is externally connected to a small air pump. The guide pipe has a herringbone structure, with one end fixed to the bottom of the receiving hopper and the other two ends respectively connected to the serrated seed metering wheel and the negative pressure seed metering disc. A baffle is rotatably connected inside the main pipe of the guide pipe.

[0011] As a further embodiment of this utility model: the drive unit includes a driving disc, a driven disc, and a belt. The driving disc is coaxially fixed on one of the traveling wheels, the driven disc is coaxially fixed on the transmission rod, and the belt is disposed between the driving disc and the driven disc.

[0012] As a further embodiment of this utility model: the adjustment unit includes a drive wheel, a connecting rod, and an adjusting rod. The drive wheel is coaxially and slidably connected to the transmission rod and is located between the serrated seed metering wheel and the negative pressure seed metering disc. A protrusion is provided on the transmission rod, and the drive wheel slides in cooperation with the protrusion. The connecting rod is fixed on both sides of the drive wheel and has positioning holes through the serrated seed metering wheel and the negative pressure seed metering disc, respectively. The positioning holes correspond one-to-one with the connecting rod. A rotating ring is rotatably sleeved on the outside of the drive wheel. One end of the adjusting rod is fixed to the rotating ring, and the other end is slidably engaged with the second support frame.

[0013] As a further improvement of this utility model: the internal cavity of the seed storage box is divided into two storage spaces by a partition, and the bottom of both storage spaces is a sloping structure, and an observation window is provided on the outer wall of the seed storage box.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the seed storage box is divided into two independent chambers, left and right, by a partition, forming a split-type double-chamber box, corresponding to two different sowing modes. The partition can be disassembled and assembled by hand, making it easy to adjust to single-chamber / double-chamber mode as needed. By pushing the feed plate to slide it to the left / right position, the through hole on it aligns with the corresponding discharge port, realizing rapid switching of sowing modes. The driving force is provided by the walking wheels, eliminating the need for a separate drive structure, which is economical and environmentally friendly. At the same time, by changing the position of the drive wheel in the adjustment unit, the docking rod aligns with the corresponding positioning hole, thereby driving the serrated seed metering wheel or negative pressure seed metering disc to quickly complete the switching of sowing modes and meet different agronomic requirements. This application achieves efficient switching of sowing modes through mechanical structural innovation, combining functionality and economy, and is particularly suitable for small and medium-sized farms and multi-crop rotation scenarios.

The wheels 2 are rotatably connected to both sides of the frame 1. The seed storage mechanism 3 and the seeding mechanism 4 are both mounted on the frame 1 and are arranged side by side.

[0025] The seed storage mechanism 3 includes a first support frame 31, a seed storage box 32, a partition 33, a discharge port 34, and a limiting unit. The first support frame 31 is fixed on the frame 1 and has a slot at the bottom of the frame 1. The seed storage box 32 is snapped into the slot. A strip-shaped groove is provided at the center of the inner wall of the seed storage box 32. The partition 33 is detachably snapped into the strip-shaped groove. The discharge port 34 is provided through the bottom sides of the seed storage box 32.

[0026] The sowing mechanism 4 includes a second support frame 41, a transmission rod 42, a drive unit and an adjustment unit. The second support frame 41 is fixed on the frame 1 and located on one side of the first support frame 31. The transmission rod 42 is rotatably connected to the second support frame 41.

[0027] The limiting unit includes a receiving hopper 35 and a discharging plate 36. The receiving hopper 35 has a T-shaped structure and is fixed on the first support frame 31 and located at the bottom of the seed storage box 32. A through groove is provided through the first support frame 31. The discharging plate 36 is slidably engaged in the through groove and is located between the seed storage box 32 and the receiving hopper 35. Two through holes are provided on the discharging plate 36, and the through holes and the discharge port 34 are located in the same plane.

[0028] The sowing mechanism 4 also includes a serrated seed metering wheel 43, a negative pressure seed metering disc 44, and a guide pipe 45. The serrated seed metering wheel 43 and the negative pressure seed metering disc 44 are coaxially rotatably connected to the transmission rod 42 and are arranged in parallel. The negative pressure seed metering disc 44 has multiple negative pressure adsorption holes on its surface and is connected to a small air pump. The guide pipe 45 has a herringbone structure, with one end fixed to the bottom of the receiving hopper 35 and the other two ends connected to the serrated seed metering wheel 43 and the negative pressure seed metering disc 44, respectively. A baffle 5 is rotatably connected inside the main pipe of the guide pipe 45. By adjusting the position of the baffle 5, the material in the guide pipe 45 can flow to the serrated seed metering wheel 43 for spot sowing or to the negative pressure seed metering disc 44 for row sowing.

[0029] The drive unit includes a drive disc 46, a driven disc 47 and a belt 48. The drive disc 46 is coaxially fixed on one of the traveling wheels 2, the driven disc 47 is coaxially fixed on the transmission rod 42, and the belt 48 is arranged between the drive disc 46 and the driven disc 47.

[0030] The adjustment unit includes a drive wheel 49, a connecting rod 410, and an adjusting rod 411. The drive wheel 49 is coaxially slidably connected to the transmission rod 42 and is located between the serrated seed metering wheel 43 and the negative pressure seed metering disc 44. A protrusion is provided on the transmission rod 42, and the drive wheel 49 slides in cooperation with the protrusion. The connecting rod 410 is fixed on both sides of the drive wheel 49 and has positioning holes through the serrated seed metering wheel 43 and the negative pressure seed metering disc 44, respectively. The positioning holes correspond one-to-one with the connecting rod 410. A rotating ring is rotatably sleeved on the outside of the drive wheel 49. One end of the adjusting rod 411 is fixed to the rotating ring, and the other end is slidably engaged with the second support frame 41.

[0031] In this invention, the seed storage box 32 is divided into two independent chambers, left and right, by a partition 33, forming a split-type double-chamber box. These chambers can store crop seeds or green manure (crop and green manure seeds) separately, corresponding to either crop sowing or green manure sowing. The partition 33 can be easily disassembled and reassembled by hand, allowing for adjustment to single-chamber or double-chamber mode as needed. In single-chamber mode, crops or green manure can be sown separately; in double-chamber mode, both crops and green manure can be sown in a single sowing process. The feeding plate 36 can be pushed to slide to the left or right position. The device is positioned so that its through hole aligns with the corresponding discharge port 34, enabling rapid switching of the sowing mode. The driving force is provided by the walking wheel 2, avoiding the need for a separate drive structure, which is economical and environmentally friendly. At the same time, by changing the position of the drive wheel 49 in the adjustment unit, the docking rod 410 aligns with the corresponding positioning hole, thereby driving the serrated seed metering wheel 43 or the negative pressure seed metering disc 44 to quickly complete the switching of the sowing mode and meet different agronomic requirements. This application achieves efficient switching of the sowing mode through mechanical structural innovation, combining functionality and economy, and is particularly suitable for small and medium-sized farms and multi-crop rotation scenarios. Example

[0032] like Figures 1 to 6 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0033] The internal cavity of the seed storage box 32 is divided into two storage spaces by a partition 33, and the bottom of both storage spaces is a sloping structure. An observation window is provided on the outer wall of the seed storage box 32 to guide the seeds to the seed discharge port by gravity and to monitor the remaining seed quantity in real time through the observation window.

[0034] Working principle: When using this seeder, first add seeds to the seed storage box 32, then push the feeding plate 36 to move so that the through hole on the feeding plate 36 aligns with the corresponding discharge port 34. At this time, the seeds fall through the discharge port 34 into the receiving hopper 35, and then through the guide pipe 45 and the partition plate 33 onto the serrated seed metering wheel 43 or the negative pressure seed metering disc 44. At this time, the movement of the device drives the traveling wheel 2 to rotate. The traveling wheel 2 drives the driven disc 47, the transmission rod 42, and the drive wheel 49 to rotate synchronously through the active disc 46 and the belt 48. At this time, the position of the drive wheel 49 is adjusted by the adjusting rod 411 so that the docking rod 410 aligns with the serrated seed metering wheel 43 or the negative pressure seed metering disc 44, and drives it to rotate for sowing. This dual-mode seed box can be used alone or in conjunction with an existing seeder. For example, when sowing crops with an existing seeder, it is also necessary to sow green manure. The seed box can be connected to the rear of the existing seeder, so that it can be used in conjunction with the existing seeder.
