Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a modular device for sowing. Background Technology

[0002] In agricultural production, the sowing process is crucial, as its efficiency and accuracy directly affect crop yield and quality. Traditional sowing devices have many limitations. From an adaptability perspective, different crops have varying requirements for seed size, shape, sowing depth, and spacing, and traditional seeders often struggle to flexibly adjust to meet these diverse needs.

[0003] Chinese Patent Publication No. CN214316201U discloses a sowing device, belonging to the field of agricultural equipment technology. The sowing device is characterized by comprising a main shaft, a handle fixedly connected to the main shaft, a shovel fixedly connected to the lower end of the main shaft, and a feeding rod. The main shaft has a through hole for the feeding rod to pass through, a discharge port at the bottom, and a feed port at the top. A cavity for accommodating seeds is formed between the feeding rod and the inner wall of the main shaft. A handle is connected to the top of the feeding rod, and a pusher that cooperates with the discharge port is provided at the bottom. A metering bin is connected to the upper opening of the discharge port. This invention allows sowing in hard natural soil, reducing the amount of pre-sowing tilling and improving sowing efficiency. It features a simple structure, ease of use, and safety, greatly reducing manual labor intensity. It also allows control over the number of seeds planted per hole, solving technical problems affecting germination and survival rates.

[0004] In existing technologies, seed quantity in a sowing device relies solely on a "quantitative bin" to achieve quantitative seed distribution. The process of seeds entering the quantitative bin from the container and exiting from the outlet lacks a structure for actively controlling the conveying speed. This can easily lead to fluctuations in the seed falling speed due to inconsistent pressure and speed of the handrail during manual operation, resulting in deviations in the number of seeds per hole (too many or too few), which may indirectly affect the germination rate. Therefore, we have made improvements to this by proposing a modular sowing device. Utility Model Content

[0017] Example 1: Please refer to the appendix of the instruction manual. Figure 1-6 A modular seeding device includes a housing 1, a top plate 21 on the top of the housing 1, a placement plate 2 fixedly installed inside the housing 1, a storage chamber 3 and a distribution chamber 4 respectively opened inside the housing 1 at the top and bottom of the placement plate 2, a discharge pipe 5 fixedly installed at the bottom of the housing 1 and communicating with the distribution chamber 4, a connecting pipe 20 fixedly installed inside the housing 1 and communicating with the storage chamber 3 and the distribution chamber 4 at both ends of the connecting pipe 20 respectively, the connecting pipe 20 passing through the placement plate 2 and fixedly connected to it, a negative pressure pump 6 embedded on one side of the discharge pipe 5, the air inlet of the negative pressure pump 6 passing through one side of the discharge pipe 5 and communicating with the distribution chamber 4, a scraper 17 provided inside the discharge pipe 5 and slidably connected to the inner wall of the discharge pipe 5, and a protective mesh plate fixedly installed inside the air inlet of the negative pressure pump 6.

[0018] In this embodiment of the invention, seeds are first loaded into the storage chamber 3. Through the connecting pipe 20 that passes through the placement plate 2, the seeds can fall naturally or enter the distribution chamber 4 under the action of subsequent auxiliary structures, completing the initial transfer of "storage-distribution". After the negative pressure pump 6 embedded on one side of the discharge pipe 5 is started, its air inlet (connected to the distribution chamber 4) generates negative pressure, which sucks the seeds in the distribution chamber 4 into the discharge pipe 5 and transports them to the sowing area through the discharge pipe 5, achieving precise feeding. The scraper 17 inside the discharge pipe 5 can slide along the inner wall to remove any seeds or impurities that may remain in the discharge pipe 5, avoiding blockage. At the same time, the protective mesh plate fixed inside the air inlet of the negative pressure pump 6 can prevent seeds or foreign objects from entering the inside of the negative pressure pump 6, protecting the pump body from damage and extending the service life of the equipment. In this embodiment of the utility model, a complete "storage-distribution-discharge" seed transfer path is constructed through the cooperation of the storage chamber 3, the distribution chamber 4, the connecting pipe 20 and the discharge pipe 5, which meets the basic functional requirements of the sowing device. The negative pressure power provided by the negative pressure pump 6 can avoid the "material interruption" or "material accumulation" problems that are easy to occur in traditional gravity discharge, and ensure the continuity and uniformity of seed delivery. The dual design of the protective mesh plate and the scraper 17 not only protects the core power component (negative pressure pump 6) but also prevents the discharge channel from being blocked, reduces the equipment failure rate and reduces maintenance costs.

[0019] Example 2: Please refer to the appendix of the instruction manual. Figure 1-7 In a preferred embodiment of this utility model, the top of the placement plate 2 is inclined and the lowest end faces the connecting pipe 20. A second micro servo motor 15 is fixedly installed inside the feeding pipe 5. A gear 18 is fixedly installed at the output end of the second micro servo motor 15 and is rotatably connected to the feeding pipe 5. An outer gear ring 16 meshes with the outer side of the gear 18 and is slidably connected to the feeding pipe 5. The scraper 17 is fixedly connected to the inner wall of the outer gear ring 16. The outer gear ring 16 has the same inner diameter as the feeding pipe 5, and the outer diameter of the outer gear ring 16 is smaller than the outer diameter of the feeding pipe 5.

[0020] Limiting plates 19 are fixedly installed at the top and bottom of the external gear ring 16. Both limiting plates 19 are slidably connected to the feed pipe 5. A valve is provided inside the housing 1 and on the connecting pipe 20.

[0021] On the corresponding sides of the housing 1, a U-shaped fixing seat 27 and a T-shaped insert plate 28 are fixedly installed respectively. The T-shaped insert plate 28 is inserted into the U-shaped fixing seat 27 and slidably connected to it. On the side of the T-shaped insert plate 28 away from the housing 1, there are four corners with second fixing screws 29. Several second fixing screws 29 pass through the T-shaped insert plate 28 and are threadedly connected to it. Several second fixing screws 29 are inserted into the housing 1 and are threadedly connected to it.

[0022] The top of the U-shaped fixing seat 27 is provided with two third fixing screws, and both third fixing screws are inserted into the interior of the U-shaped fixing seat 27 and threadedly connected to it. The T-shaped insert plate 28 is provided with several bolt grooves that cooperate with the third fixing screws.

[0023] U-shaped insert plates 25 are provided on both sides of the top plate 21. Both U-shaped insert plates 25 are inserted into the interior of the housing 1 and the top plate 21 and are slidably connected thereto. Several first fixing screws 26 are provided on the side of the two U-shaped insert plates 25 away from the housing 1. Several first fixing bolts pass through the U-shaped insert plates 25 and are threadedly connected thereto. The several first fixing screws 26 are respectively inserted into the interior of the housing 1 and the top plate 21 and are threadedly connected thereto.

[0024] A photovoltaic panel 22 is fixedly installed on the top of the top plate 21. Two batteries 23 are installed inside the housing 1. The photovoltaic panel 22 is electrically connected to the two batteries 23. The batteries 23 are electrically connected to the negative pressure pump 6, the infrared sensor 14, the second micro servo motor 15, and the valve.

[0025] An infrared sensor 14 is embedded on one side of the inner wall of the housing 1 and on the side of the material distribution chamber 4. A transparent window is provided on the housing 1. A flange is fixedly installed on the outer side of the end of the feeding pipe 5 away from the housing 1. A control module 24 is fixedly installed inside the housing 1. The control module 24 is electrically connected to the negative pressure pump 6, the infrared sensor 14, the second micro servo motor 15, the battery 23 and the valve. The control module 24 is also electrically connected to the external controller.

[0026] In this embodiment of the invention, the top of the placement plate 2 is designed to be inclined, with its lowest end facing the connecting pipe 20. Gravity guides the seeds in the storage chamber 3 towards the connecting pipe 20, preventing seed accumulation on the top of the placement plate 2 and ensuring smooth entry of the seeds into the dispensing chamber 4. After the second micro servo motor 15, fixed inside the feeding pipe 5, is started, its output drives the gear 18 to rotate. Since the gear 18 meshes with the external gear ring 16, and the external gear ring 16 is slidably connected to the feeding pipe 5, the gear 18... The rotation of 8 is converted into the circumferential sliding of the outer gear ring 16 along the inner wall of the feed pipe 5; while the scraper 17 is fixedly connected to the inner wall of the outer gear ring 16, so the outer gear ring 16 drives the scraper 17 to slide synchronously, realizing the comprehensive cleaning of the inner wall of the feed pipe 5; the inner diameter of the outer gear ring 16 is the same as the inner diameter of the feed pipe 5, ensuring that there is no gap when the outer gear ring 16 slides, and preventing seeds from leaking out from the gap; the outer diameter of the outer gear ring 16 is smaller than the outer diameter of the feed pipe 5, preventing the outer gear ring 16 from interfering with the external structure of the feed pipe 5, and ensuring smooth sliding.

[0027] The limiting plate 19, which is fixed at the top and bottom of the outer gear ring 16, can slide along the inner wall of the feeding pipe 5. Its function is to limit the axial displacement of the outer gear ring 16 during the sliding process, and prevent the outer gear ring 16 from disengaging from the meshing range of the gear 18 due to excessive sliding, so as to ensure that the gear 18 and the outer gear ring 16 always maintain stable transmission. The valve set on the connecting pipe 20 inside the housing 1 can adjust the valve opening through the control module 24, thereby controlling the flow rate of seeds delivered from the storage chamber 3 to the distribution chamber 4. The feeding speed can be flexibly adjusted according to the sowing requirements (such as sowing density and seed size) to avoid too many or too few seeds in the distribution chamber 4 affecting the sowing accuracy.

[0028] In this embodiment of the invention, when multiple devices need to be used in combination (e.g., to expand the sowing width), the T-shaped insert plate 28 of one device is inserted into the U-shaped fixing seat 27 of another device. The sliding fit between the T-shaped insert plate 28 and the U-shaped fixing seat 27 achieves the initial docking of the two devices. Subsequently, four second fixing screws 29 are inserted through the T-shaped insert plate 28 and screwed into the housing 1 of the two devices respectively. The two devices are fixed into a whole by threaded connection, completing the modular splicing. After the T-shaped insert plate 28 is inserted into the U-shaped fixing seat 27 and initially fixed by the second fixing screws 29, two third fixing screws are screwed in from the top of the U-shaped fixing seat 27, so that their ends are inserted into the preset bolt grooves on the T-shaped insert plate 28. Through the cooperation of the third fixing screws and the bolt grooves, the connection between the T-shaped insert plate 28 and the U-shaped fixing seat 27 is limited a second time, further enhancing the splicing stability.

[0029] When installing the top plate 21, insert two U-shaped inserts 25 into the corresponding slots of the housing 1 and the top plate 21 respectively. The "clamping" action of the U-shaped inserts 25 achieves the initial positioning of the top plate 21 and the housing 1. Then, several first fixing screws 26 are inserted through the U-shaped inserts 25 and screwed into the threaded holes of the housing 1 and the top plate 21 respectively to complete the fixing of the top plate 21. When disassembling, simply unscrew the first fixing screws 26 to pull out the U-shaped inserts 25, thereby separating the top plate 21 from the housing 1, which facilitates the cleaning or maintenance of the inside of the storage chamber 3.

[0030] The photovoltaic panel 22 fixed on the top of the top plate 21 converts solar energy into electrical energy under sunlight and sends it to the two batteries 23 inside the casing 1 for storage. The batteries 23 serve as power sources to supply power to the negative pressure pump 6, infrared sensor 14, second micro servo motor 15 and valves on the connecting pipe 20, ensuring the normal operation of each electrical component.

[0031] An infrared sensor 14 embedded on one side of the inner wall of the housing 1 (at the distribution chamber 4) can monitor the seed quantity in the distribution chamber 4 in real time. When the seed quantity is lower than the preset threshold, the infrared sensor 14 sends a signal to the control module 24. The control module 24 can automatically open the valve on the connecting pipe 20 to replenish the seeds or issue an early warning to the operator. The transparent window set on the housing 1 allows the operator to intuitively observe the seed status in the storage chamber 3 and the distribution chamber 4, assisting in manual judgment and intervention. The flange on the outer side of the end of the discharge pipe 5 facilitates connection with external sowing pipes or equipment, expanding the application scenarios of the device. The control module 24 inside the housing 1 serves as the core control unit and is electrically connected to the negative pressure pump 6, the infrared sensor 14, the second micro servo motor 15, the battery 23, and the valves. It can also communicate with external controllers (such as remote controllers and agricultural machinery control systems) to realize remote adjustment and automated control of sowing parameters (discharge speed, cleaning frequency).

[0032] Example 3: Please refer to the appendix of the instruction manual. Figure 2 , Figure 4 and Figure 5 In a preferred embodiment of this utility model, a first micro servo motor 7 is fixedly installed inside the placement plate 2. A T-shaped rotating rod 8 is fixedly installed at the output end of the first micro servo motor 7, and the T-shaped rotating rod 8 passes through the bottom of the placement plate 2 and is rotatably connected to it. Side plates 12 are fixedly installed on both sides of the T-shaped rotating rod 8, and both side plates 12 are slidably connected to the placement plate 2. An annular cylinder 9 is slidably connected to the outside of the T-shaped rotating rod 8, and several partitions 10 are fixedly installed on the outside of the annular cylinder 9. An electric telescopic rod 1 is embedded in the bottom of both side plates 12. 3. The output ends of the two electric telescopic rods 13 are fixedly connected to the partition plate 10. A T-shaped rod 11 is fixedly installed at the bottom of the annular cylinder 9. The T-shaped rod 11 passes through the bottom of the housing 1 and is slidably connected to it. The T-shaped rotating rod 8 is inserted into the interior of the T-shaped rod 11 and is slidably connected to it. The T-shaped rotating rod 8, the T-shaped rod 11, the two side plates 12 and several partition plates 10 are rotatably connected to the material distribution chamber 4. The battery 23 is electrically connected to the first micro servo motor 7 and the electric telescopic rod 13. The control module 24 is electrically connected to the first micro servo motor 7 and the electric telescopic rod 13.

[0033] In this embodiment of the invention, after the first micro servo motor 7 fixed inside the placement plate 2 is started, its output end drives the T-shaped rotating rod 8 to rotate; the side plates 12 on both sides of the T-shaped rotating rod 8 rotate synchronously with the T-shaped rotating rod 8. At the same time, the electric telescopic rod 13 embedded at the bottom of the side plate 12 can extend and retract, driving the partition plate 10 and the annular cylinder 9 fixed to the output end of the electric telescopic rod 13 to slide longitudinally along the T-shaped rotating rod 8; since the bottom of the inner wall of the housing 1 is conical (with a small top opening), when the partition plate 10 moves down to contact the bottom of the inner wall of the housing 1, it can dissipate the contents of the dispensing chamber 4. The materials in the part are separated; the annular cylinder 9 is slidably connected to the T-shaped rotating rod 8, and the T-shaped rod 11 is fixed to the annular cylinder 9 and moves synchronously with the annular cylinder 9 to ensure that the position of the partition 10 is stable during the movement; the seeds in the distribution chamber 4 enter the "distribution grid" formed by the adjacent partition 10, and the materials are separated by the downward movement of the partition 10. With the rotation of the partition 10 and the conical design of the top of the inner wall of the shell 1, the materials are discharged in an orderly manner through the position connected to the discharge pipe 5, so that the seeds are evenly distributed and transported to the inlet of the discharge pipe 5, and the negative pressure pump 6 is used to achieve uniform discharge. In this embodiment of the utility model, the longitudinal sliding separation and rotation of the partition 10, combined with the special conical inner wall structure of the shell 1, can precisely control the number of seeds in each sowing unit, avoiding the problems of "too many seeds" or "too few seeds". The partition 10 can be flexibly adjusted in the longitudinal position by the electric telescopic rod 13. Combined with the conical inner wall of the shell 1, it is suitable for seeds of different sizes and sowing densities, improving the versatility of the device. The control module 24, together with the first micro servo motor 7 and the electric telescopic rod 13, realizes the automatic adjustment of the material distribution process without manual intervention, further improving the sowing efficiency and consistency.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
