Description

Technical Field

[0001] This utility model relates to the field of precision quantitative seeding technology, and in particular to a precision quantitative seeding device for sowing Angelica dahurica. Background Technology

[0002] In modern agricultural production, the precision of sowing has a crucial impact on the subsequent growth, yield, and quality of crops. With the continuous advancement of agricultural modernization, growers have an increasingly urgent need for equipment capable of precise, quantitative sowing. For Angelica dahurica, a common Chinese medicinal herb, its seeds are typically small and irregularly shaped. Traditional manual sowing methods have many drawbacks. For example, it is difficult to precisely control the sowing rate, easily leading to over-sowing, wasting seeds and increasing planting costs, or under-sowing, resulting in insufficient seedlings and affecting the final yield. Furthermore, manual sowing is inefficient and often fails to meet the timing requirements for large-scale planting, severely restricting the large-scale and standardized development of Angelica dahurica cultivation.

[0003] In the current agricultural sowing field, existing seed planters have revealed many unresolved problems when applied to the sowing of Angelica dahurica. On the one hand, uneven mixing often occurs during the seed mixing stage, causing Angelica dahurica seeds to clump together, which in turn affects the subsequent sowing process, resulting in uneven seed dispersion during dispensing and impacting the uniformity of sowing in the field. On the other hand, the inflexible adjustment of seed quantity is also a major pain point. Different planting environments, soil conditions, and planting plans have different requirements for the seed quantity of Angelica dahurica, but existing seed metering devices cannot flexibly adjust the seed quantity according to actual needs, which greatly limits the scientific and precise nature of Angelica dahurica sowing and seriously hinders the development of the Angelica dahurica planting industry towards high efficiency and high quality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a precise quantitative seed metering device for angelica sowing, comprising a base 1, a discharge box 2 fixedly connected to the top of the base 1, a mixing box 3 fixedly connected to the top of the discharge box 2, a filter plate 9 provided on the inner wall of the mixing box 3, sliding grooves provided on the inner walls of the front and rear sides of the base 1, and a first spring 14 provided on the inner wall of the sliding grooves, a rotating rod 6 rotatably connected to the front inner wall of the mixing box 3, a rotating rod 7 rotatably connected to the rear side of the mixing box 3, a gear 10 fixedly connected to the right end of both the rotating rod 6 and the rotating rod 7, the outer walls of the two gears 10 meshing together, several mixing plates 8 fixedly connected to the outer walls of both the rotating rod 6 and the rotating rod 7, and a drive plate 8 provided on the left outer wall of the mixing box 3. The moving assembly includes a rotating rod 11 rotatably connected to the inner wall of the bottom of the mixing tank 3. Cams 12 are fixedly connected to both ends of the rotating rod 11. A rotating rod 6 is connected to the rotating rod 11 through a transmission assembly. The driving assembly includes an L-shaped plate 4 fixedly connected to the outer wall of the left side of the mixing tank 3. A first motor 5 is installed on the outer wall of the left side of the L-shaped plate 4. The driving end of the first motor 5 is fixedly connected to the left end of the rotating rod 6. The transmission assembly includes a pulley 13 fixedly connected to the outer wall of the left end of the rotating rod 6 and the rotating rod 11. The two pulleys 13 are connected by a belt. The top end of the first spring 14 is connected to the bottom end of the filter plate 9. The bottom end of the first spring 14 is connected to the inner wall of the chute. The outer wall of the filter plate 9 is slidably connected to the inner wall of the chute.

[0027] Specifically, base 1 provides stable support for unloading box 2, forming the basic installation structure of the seed metering device. Unloading box 2 connects mixing box 3 and base 1, allowing seeds to enter unloading box 2 from mixing box 3, forming a seed conveying channel. L-shaped plate 4 provides installation support for first motor 5. The drive end of first motor 5 is fixedly connected to the left end of rotating rod 6, providing power to drive rotating rod 6 to rotate. Rotating rod 6 can rotate and drive mixing plate 8 and gear 10 to rotate, providing mixing power. Rotating rod 7 can rotate and drive mixing plate 8 and gear 10 to rotate, cooperating with rotating rod 6 to achieve uniform mixing. The outer walls of the two gears 10 mesh, so that when rotating rod 6 rotates, it drives rotating rod 7 to rotate in the opposite direction, allowing mixing plate 8 to perform bidirectional mixing of seeds, preventing clumping. Mixing plate 8 rotates with rotating rod to mix seeds, breaking up clumped seeds, facilitating subsequent filtration and seed metering.

[0028] Rotating rod 11 can rotate and drive cam 12 to rotate, providing power for the vibration of filter plate 9. Cam 12 is located below filter plate 9. When rotating with rotating rod 11, it lifts filter plate 9, and with the first spring 14, it makes filter plate 9 vibrate up and down, enhancing the filtration effect. The two pulleys 13 are connected by a belt. Their function is to transmit the power of rotating rod 6 to rotating rod 11, so that rotating rod 11 rotates synchronously with rotating rod 6. Filter plate 9 screens angelica seeds and filters impurities to ensure that the seeds entering the subsequent stages are qualified. The chute provides a sliding track for filter plate 9 to ensure stable sliding of filter plate 9. The elastic force of the first spring 14 makes filter plate 9 vibrate, enhancing the filtration effect and preventing filter plate 9 from clogging. This seed metering device drives rotating rod 6, rotating rod 7 and stirring plate 8 through first motor 5 to stir and prevent agglomeration. With the help of pulley 13, rotating rod 11 and cam 12, in conjunction with the first spring 14, make filter plate 9 vibrate in chute. Overall, it achieves uniform stirring of seeds, efficient filtration and anti-clogging, and ensures that the seeds entering unloading box 2 are qualified.

[0029] Reference Figure 4 - Figure 6A protective box 15 is fixedly connected to the left outer wall of the base 1. The protective box 15 is connected to a turntable 19 via a rotating assembly. The inner wall of the turntable 19 has several metering through holes 20. The rotating assembly includes a second motor 16 fixedly connected to the top of the protective box 15. A rotating shaft 17 is fixedly connected to the drive end of the second motor 16. A gear 18 is fixedly connected to the outer wall of the rotating shaft 17. A gear ring 21 is meshed with the outer wall of the gear 18. The outer wall of the gear ring 21 is rotatably connected to the inner wall of the base 1. The outer wall of the turntable 19 is fixedly connected to the inner wall of the gear ring 21. An adjusting plate 24 is slidably connected to the inner wall of the unloading box 2. The bottom of the unloading box 2 has a discharge port 23. The left outer wall of the unloading box 2 is fixedly connected to the mounting box 25. The rear inner wall of the mounting box 25 is slidably connected to the pressure plate 26. The front end of the pressure plate 26 is fixedly connected to the insertion rod 27. The inner wall of the mounting box 25 is provided with a second spring 28. The bottom of the adjusting plate 24 has several adjusting holes. The size of the adjusting holes is adapted to the insertion rod 27. The top end of the second spring 28 is connected to the bottom end of the insertion rod 27. The bottom end of the second spring 28 is connected to the inner wall of the mounting box 25. The rear top end of the base 1 is provided with a main through hole corresponding to the bottom end of the discharge port 23. The front bottom inner wall of the base 1 is provided with a discharge port 22.

[0030] Specifically, the protective box 15 protects the internal rotating assembly from external interference. Power is transmitted to the turntable 19 via the rotating assembly, causing the turntable 19 to rotate and achieve seed dispensing. The second motor 16 provides power for the rotation of the turntable 19 and transmits this power to the rotating shaft 17, causing the rotating shaft 17 to rotate. Gear 18 rotates with the rotating shaft 17, transmitting power to the gear ring 21. Through gear meshing, the rotation of gear 18 is converted into the rotation of the gear ring 21, driving the turntable 19. The turntable 19 rotates synchronously with the gear ring 21, achieving seed dispensing through the quantitative through-hole 20. The quantitative through-hole 20 quantitatively accommodates seeds, achieving precise quantitative seed dispensing.

[0031] The adjusting plate 24 can slide along the inner wall of the unloading box 2 to adjust the opening and closing size of the discharge port 23 and control the amount of seeds. The discharge port 23 serves as the channel for seeds to be discharged from the unloading box 2. The mounting box 25 provides installation space for components such as the pressure plate 26 and the insertion rod 27. The pressure plate 26 can slide within the mounting box 25, driving the insertion rod 27 to move to control its engagement with the adjusting hole. The insertion rod 27 moves with the pressure plate 26, inserting or disengaging from the adjusting hole, thus fixing or adjusting the adjusting plate 24. The elastic force of the second spring 28 keeps the insertion rod 27 inserted into the adjusting hole. The elastic force of the second spring 28 is greater than the frictional force on the insertion rod 27, ensuring that the insertion rod 27 is engaged with the second spring 28 when the pressure plate 26 is not pressed. Under the action of the mechanism, the adjustment plate 24 is stably inserted into the adjustment hole of the adjustment plate 24, preventing the insertion rod 27 from dislodging itself due to friction, thus ensuring the fixed position of the adjustment plate 24, stabilizing the opening and closing size of the feed port 23, and ensuring the reliability of the seed quantity adjustment. The adjustment plate 24 is fixed and compressed when pressed for adjustment. The size of the adjustment hole is adapted to the insertion rod 27. By cooperating with the insertion rod 27, the adjustment plate 24 is fixed in different positions to achieve multi-level adjustment of the feed quantity. The main through hole allows the seeds discharged from the feed port 23 to enter the quantitative through hole 2 of the turntable 19. When the quantitative through-hole 20 is aligned with the discharge port 23, the seeds in the unloading box 2 are allowed to fall into the quantitative through-hole 20; when the quantitative through-hole 20 is not aligned with the discharge port 23, a closed state is formed to prevent the seeds from leaking out, ensuring that the quantitative seeding is accurate and controllable. Then, the discharge port 22 serves as the final channel for the seeds to be discharged from the seed meterer, completing the sowing process. This structure drives the rotating component to drive the turntable 19 through the second motor 16, and achieves precise sealing and leakage prevention with the help of the quantitative through-hole 20. Overall, it ensures accurate and controllable sowing, adjustable seeding amount, and efficient completion of the sowing process.

[0032] Working principle: After the seeds are placed into the mixing tank 3, the first motor 5 starts, and its drive end drives the rotating rod 6 to rotate. The rotating rod 6 drives the rotating rod 7 to rotate in the opposite direction through the meshing gear 10. The mixing plates 8 on the rotating rod 6 and the rotating rod 7 rotate with it, and the seeds are mixed in both directions to break up the clumps. At the same time, the rotating rod 6 drives the rotating rod 11 to rotate through the pulley 13 and the belt. The cam 12 on the rotating rod 11 rotates with it and lifts the filter plate 9. The filter plate 9 slides in the groove and vibrates up and down with the elastic force of the first spring 14 to screen the mixed seeds and filter out impurities. Qualified seeds fall into the unloading box 2. The second motor 16 starts, and its drive end drives the rotating shaft 17 to rotate. The gear 18 on the rotating shaft 17 rotates with it and meshes to drive the gear ring 21 to rotate. 21 drives the inner wall turntable 19 to rotate synchronously; the seeds in the unloading box 2 pass through the discharge port 23 and the main through hole of the base 1. When the quantitative through hole 20 on the turntable 19 rotates to align with the discharge port 23, the seeds fall into the quantitative through hole 20. When they are not aligned, the top of the turntable 19 and the discharge port 23 form a seal to prevent seed leakage. If it is necessary to adjust the seeding amount, press the pressure plate 26 in the mounting box 25. The pressure plate 26 drives the insertion rod 27 to compress the second spring 28 and disengage from the adjustment hole of the adjustment plate 24. Slide the adjustment plate 24 to change the opening and closing size of the discharge port 23. After adjustment, release the pressure plate 26, and the second spring 28 resets so that the insertion rod 27 is inserted into the corresponding adjustment hole to fix the adjustment plate 24. Finally, the quantitative through hole 20 containing the seeds rotates with the turntable 19 to correspond to the discharge port 22 of the base 1, and the seeds are discharged from the discharge port 22 to complete the sowing.
