Description

Technical Field

[0001] This invention relates to the field of seeder technology, and more particularly to the field of reseeding in seeders, specifically to a high-speed and precise reseeding system for high-vitality corn seeds with dual-compartment synergy. Background Technology

[0002] Precision seeding technology is a core means of saving seeds, improving quality, and increasing production efficiency in modern agriculture. Its core requirement is to achieve precise seed placement and uniform distribution. In large-scale corn planting, high-speed seeding has become the mainstream operation mode. In order to ensure the accuracy of seeding and reduce missed seeding, supplementary devices are usually added.

[0003] However, existing precision seeders still have many technical shortcomings: First, they cannot detect seed viability in real time and accurately, resulting in the sowing of inactive, shriveled, or damaged seeds along with qualified seeds, leading to low germination rates and uneven seedling distribution in the field. Second, traditional reseeding devices mostly use a single-compartment seed storage design, which has limited storage capacity and slow reseeding response speed, making it difficult to adapt to the continuous reseeding needs in high-speed seeding scenarios. Third, reseeding devices have poor compatibility with existing seeders and are mostly designed for single crops, lacking versatility. Therefore, developing a system that integrates real-time viability detection, dual-compartment collaborative seed storage, high-speed and accurate reseeding, and multi-crop compatibility is of great significance for solving the pain points of existing technologies and improving the quality of large-scale precision seeding operations. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a dual-compartment collaborative high-vitality corn seed high-speed precision replanting system. It enables real-time seed vigor determination, precise removal of unqualified seeds, orderly caching of qualified seeds, and high-speed directional replanting, thereby improving germination rate, sowing uniformity, and operational efficiency. It solves the technical problems of existing precision sowing and replanting devices, such as the inability to accurately detect seed vigor in real time, slow replanting response, and poor adaptability.

[0005] This invention is achieved through the following technical solution: a high-velocity, high-speed, and precise reseeding system for maize seeds with dual-compartment coordination, comprising a small seed box, an air-suction seed metering device, a seed diversion and storage module, and a seed delivery module. The small seed box is connected to the inlet of the air-suction seed metering device, and the outlet of the air-suction seed metering device is connected to a seed metering pipe. The seed diversion and storage module includes an electromagnetic three-way reversing ball valve and two dual-compartment reseeding devices. The electromagnetic three-way reversing ball valve diverts the seeds falling from the seed metering pipe to the two dual-compartment reseeding devices. The seed delivery module includes a reversing valve, with its two inlets connected to the two dual-compartment reseeding devices respectively, and its outlet connected to the main seed pipe of the main sowing system. When the main sowing system misses a seed or the seeding is substandard, the reversing valve activates and selects seeds from one of the dual-compartment reseeding devices to enter the main seed pipe, achieving directional and precise reseeding.

[0006] This solution utilizes a dual-compartment reseeding device with alternating seed storage and supply to achieve uninterrupted continuous reseeding, making it suitable for high-speed seeding scenarios. The reversing valve can quickly switch the seed supply channel based on missed seeding signals, enabling precise directional reseeding and improving seeding uniformity. The system has a compact structure, can be directly adapted to existing seeders, has low modification costs, and is highly adaptable.

[0007] As an optimization, a viability detection module and a seed rejection module are also included. The viability detection module detects the viability of seeds falling into the seed metering tube, and the seed rejection module removes unqualified seeds detected by the viability detection module from the seed metering tube. The viability detection module and seed rejection module in this solution achieve real-time detection and automatic removal of seed viability, ensuring sowing quality from the source and improving germination rate.

[0008] As an optimization, the viability detection module includes a near-infrared spectrometer and a reflector respectively installed on both sides of the seed metering tube. In the basic scheme, the viability detection module uses a near-infrared spectrometer in conjunction with the reflector to achieve non-contact detection. Near-infrared spectroscopy technology offers high detection accuracy (≥98%), can identify inactive, shriveled, and damaged seeds, and its non-contact detection method does not damage the seeds. It also features a fast response speed, meeting the real-time detection needs of rapidly falling seeds.

[0009] As an optimization, the seed rejection module includes pneumatic nozzles and a waste seed box respectively disposed on both sides of the seed metering tube, with a rejection channel located between the pneumatic nozzles and the waste seed box on the seed metering tube. In this solution, pneumatic nozzles are used in conjunction with the waste seed box to remove substandard seeds via airflow. The pneumatic nozzles respond quickly and move precisely, instantly blowing substandard seeds out of the seed metering tube.

[0010] As an optimization, the waste seed bin includes a main body with an opening at the top and a small drawer that inserts into the main body. The waste seed bin features a pull-out drawer design, which facilitates the cleaning of waste seeds without disassembling the equipment, thus improving operational efficiency.

[0011] As an optimization, the pneumatic mouthpiece includes a mouthpiece and a solenoid directional valve. In this solution, the solenoid directional valve enables the electronic control of the pneumatic mouthpiece.

[0012] As an optimization, the dual-compartment reseeding device includes a hollow reseeding body, two reseeding drive shafts connected within the reseeding body, and a belt wound between the two reseeding drive shafts. Multiple paddles are fixed to the outer side of the belt, and adjacent paddles form a receiving cavity to accommodate a single seed. The reseeding body is connected to the outlet of an electromagnetic three-way reversing ball valve and the inlet of a reversing valve on both sides. In this design, the dual-compartment reseeding device uses a belt drive combined with a paddle structure to form a receiving cavity for storing seeds. The paddle-type belt design arranges the seeds in an orderly manner, preventing damage from mutual compression.

[0013] As an optimization, the replenishment unit is equipped with a replenishment detector to detect the number of seeds inside, so as to replenish the seeds in a timely manner. This allows for real-time monitoring of the seed quantity within the replenishment unit.

[0014] As an optimization, the two dual-compartment reseeding devices alternately store seeds. When one device supplies seeds via a reversing valve, the other device replenishes its seed supply. This scheme achieves seamless switching of the seed supply channel, ensuring a constant supply of seeds during reseeding, completely resolving the reseeding interruption problem caused by insufficient single-compartment storage capacity, and significantly reducing the missed reseeding rate. As an optimization, the seed box is fixedly connected to the seeder body via a seed box connector. This facilitates installation, debugging, and maintenance, and the installation angle can be adjusted according to different seeder models, improving adaptability.

[0015] The beneficial effects of this invention are as follows: 1. Accurate detection and rapid response: Adopting high-precision near-infrared spectroscopy detection technology, the seed vigor detection accuracy rate is ≥98%; each execution component responds quickly, and the total response time for reseeding is ≤200ms, making it suitable for high-speed sowing scenarios.

[0016] 2. Dual-compartment coordination and continuous operation: The dual-compartment belt seed conveyor supports alternating seed storage and continuous seed supply, completely solving the problem of seed replenishment interruption caused by insufficient seed storage capacity in a single compartment, and further reducing the rate of missed replenishment.

[0017] 3. Wide adaptability and strong versatility: It can be adapted to most models of precision seeders on the market through adaptive connection components without modifying the main structure.

[0018] 4. High efficiency and seed saving: High-speed seed metering and precise reseeding work together to improve the efficiency of sowing operations; unqualified seeds are automatically removed and recycled to reduce planting costs; all parts are made of wear-resistant materials, with a long service life and low maintenance costs.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] like Figures 1-8 As shown, the present invention discloses a dual-compartment collaborative high-vitality corn seed high-speed precision reseeding system, comprising a small seed box 201, an air-suction seed metering device 204, a viability detection module, a seed rejection module, a seed diversion and storage module, and a seed conveying module. Each module works collaboratively through mechanical connections and electrical signal transmission, adapting to the reseeding needs of existing precision seeders and enabling precise corn reseeding operations. The seeder body 12 provides the mounting support foundation for each module, while the large seed box 1 supplies seeds to the main seeder system, discharging the seeds through the main seed metering device 16 and the main seed tube 8. The reseeding system 2 of the present invention is deployed on one side of the seeder body 12, forming an integrated structure for coordinated main seeding and reseeding operations.

[0022] The seed box 201 adopts a hollow box structure with an open top, and its volume is adapted to the continuous reseeding needs in high-speed sowing scenarios. An internal seed guide ramp ensures smooth seed descent without retention. The seed box 201 is fixedly connected to the seeder body 12 via a seed box connector 203. The seed box connector 203 adopts a detachable connection structure and is fixed to the seeder body 12 with bolts, facilitating installation, debugging, and maintenance. Furthermore, the installation angle can be adjusted according to different seeder models, improving adaptability.

[0023] The small seed box 201 is connected to the inlet of the air suction seed metering device 204 through a square seed guide tube 202, and the outlet of the air suction seed metering device 204 is connected to a vertical seed metering tube 2045.

[0024] The air-suction seed metering device 204 is existing technology, and its structure is not specifically limited, for example... Figure 3 One structure of the device is a pneumatic seed metering device 204, which includes a front cover 2041, a drive shaft 2042, a seed metering disc 2043, a side plate 2044, a seed metering tube 2045, and an auxiliary wheel 2046. During operation, the drive shaft 2042 is linked to the power system of the seeder body 12. The pneumatic seed metering disc 2043 uses negative pressure adsorption to accurately pick up individual seeds. The size of the suction holes on the surface of the disc is adapted to the target seed size. The side plate 2044 restricts seed movement to ensure better operation. The auxiliary wheel 2046 delivers seeds into the holes, ensuring seed adsorption. It receives signals from near-infrared devices and detection devices in each replenishment chamber to trigger operation. When a replenishment chamber sends a signal indicating the need for seed introduction, it will perform a one-time operation. The seed metering tube 2045 is vertically arranged to provide a smooth seed transport channel and avoid seed jamming.

[0025] The viability detection module detects the viability of seeds falling into the seed metering tube 2045, and the seed rejection module removes unqualified seeds detected by the viability detection module from the seed metering tube 2045. The viability detection module includes a near-infrared spectrometer 213 and a reflector 205 respectively disposed on both sides of the seed metering tube 2045, and also includes a near-infrared gateway connector 212.

[0026] Near-infrared spectrometer 213 and reflector 205 are installed opposite each other at the outlet of air suction seed meter 204, and there is no obstruction between them, forming a closed detection optical path. Near-infrared spectrometer 213 establishes data transmission with control unit through near-infrared gateway connector 212, and uses near-infrared spectroscopy technology to perform non-contact viability detection on falling seeds, which can accurately identify inactive seeds, shriveled seeds and damaged seeds.

[0027] The seed rejection module is located below the viability detection module. The seed rejection module includes pneumatic nozzles 206 and waste seed boxes 211 respectively set on both sides of the seed discharge pipe 2045. The pneumatic nozzles 206 include nozzles 2061 and electromagnetic reversing valves 2062, which are installed behind the seed detection station. The electromagnetic reversing valves 2062 are electrically connected to the control unit. When unqualified seeds are detected, the control unit instantly triggers the electromagnetic reversing valves 2062 to operate, and the nozzles 2061 spray high-pressure airflow to blow the unqualified seeds out from the inside of the seed discharge pipe 2045 to the outside.

[0028] The waste seed box 211 includes a waste seed box body 2111 with an opening at the top and a small drawer 2112 inserted into the waste seed box body 2111. The small drawer 2112 adopts a pull-out design, which facilitates regular cleaning of substandard seeds and avoids accumulation and blockage.

[0029] The seed metering pipe 2045 is provided with a rejection channel located between the pneumatic nozzle 206 and the waste seed box 211. A rejection guide tube 2113 is connected to the side of the seed metering pipe 2045 near the waste seed box 211. An opening is made on the side of the seed metering pipe 2045 near the pneumatic nozzle 206, and the opening and the rejection guide tube 2113 form a rejection channel.

[0030] The seed diversion and storage module includes an electromagnetic three-way reversing ball valve 207 and two dual-compartment replanting devices 208. The electromagnetic three-way reversing ball valve 207 has an inlet at its upper end, which is connected to the lower end of the seed discharging pipe 2045. The electromagnetic three-way reversing ball valve 207 has two outlets at its lower end, which are respectively connected to the two dual-compartment replanting devices 208. The electromagnetic three-way reversing ball valve 207 diverts the seeds falling in the seed discharging pipe 2045 to the two dual-compartment replanting devices 208.

[0031] like Figure 5 As shown, the dual-compartment reseeding device 208 includes a hollow reseeding body 2083, two reseeding drive shafts 2082 shafted inside the reseeding body 2083, and a belt wound between the two reseeding drive shafts 2082. Multiple paddles are fixed to the outer side of the belt, and adjacent paddles form a cavity for accommodating a single seed. The belt is driven by the reseeding drive shafts 2082 to achieve orderly arrangement and storage of qualified seeds, avoiding damage caused by mutual squeezing and collision. The reseeding body 2083 is connected to the outlet of an electromagnetic three-way reversing ball valve 207 and the inlet of a reversing valve 210 on both sides.

[0032] The replenishment unit 2083 is equipped with a replenishment detector 2084, which detects the number of seeds contained in the unit to facilitate timely seed replenishment. The replenishment detector 2084 uses a photoelectric switch, and its corresponding detector accessory 2085 is a reflector, used in conjunction with the photoelectric switch. Two replenishment detectors 2084 are installed on either side of the dual-compartment replanting device 208 to detect the number of seeds in the replenishment compartments, enabling timely seed replenishment. The photoelectric sensing principle monitors the seed quantity in the compartments in real time. When the seed quantity in the compartment falls below a set threshold, a replenishment signal is triggered. The dual-compartment design ensures uninterrupted seed supply during replanting, improving response speed and further reducing the rate of missed replenishment.

[0033] The seed delivery module includes a seed guide tube 209 and a reversing valve 210. The two inlets of the reversing valve 210 are respectively connected to two dual-compartment replanting devices 208. The outlet of the reversing valve 210 is connected to the main seed tube 8 of the main seeding system through the seed guide tube 209. The seed guide tube 209 is made of wear-resistant plastic material with a smooth inner wall to reduce friction loss during seed delivery.

[0034] The reversing valve 210 is synchronized with the sowing signals of the control unit and the main seed tube 8. When the main sowing system misses a sowing or the sowing is unqualified, the reversing valve 210 activates and selects seeds from one of the dual-compartment reseeding devices 208 to enter the main seed tube 8, achieving directional and precise reseeding. The two dual-compartment reseeding devices 208 store seeds alternately. When one dual-compartment reseeding device 208 supplies seeds through the reversing valve 210, the other dual-compartment reseeding device 208 is filled with seeds.

[0035] Method of using this invention: During operation, the seeds to be replanted are first loaded into the small seed box 201. The seeds fall through the square seed guide tube 202 to the air suction seed metering device 204. After the device is started, the air suction seed metering disc 2043 achieves single-seed metering through negative pressure adsorption. When the metered seeds pass through the seed metering tube 2045, the near-infrared spectrometer 213 and the reflector 205 work together to complete the seed vigor detection. The detection signal is transmitted to the control unit in real time. The control unit analyzes and processes the signal. If the seed is unqualified, the pneumatic nozzle 206 is triggered to blow it into the waste seed box body 2111 through the seed rejection guide tube 2113. If the seed is qualified, the electromagnetic three-way reversing ball valve 207 is controlled to guide the seed into the two double-compartment replanting devices 208. The seed replenishment detector 2084 monitors the seed quantity in the seed bin in real time to ensure that there are always sufficient seeds in the seed bin. When a seeding failure occurs in the main seeding system, the main seed tube 8 sends a seed replenishment signal to the control unit. The control unit activates the corresponding dual seed replenishment device 208 according to the seeding failure position command of the reversing valve 210, and drives the seed replenishment transmission shaft 2082 to replenish the seed. Qualified seeds enter the main seed tube 8 through the seed guide tube 209 to complete the directional and precise seed replenishment.

[0036] When the machine first starts working, it defaults to feeding qualified seeds into the No. 1 dual-compartment replanting device 208. Once the No. 1 dual-compartment replanting device 208 is full, it begins operation. The reversing valve 210, by default, takes seeds from the No. 1 dual-compartment replanting device 208 for replanting and sends a signal back to control the electromagnetic three-way reversing ball valve 207 to feed seeds into the No. 2 dual-compartment replanting device 208. The detectors in each dual-compartment replanting device 208 monitor the seed quantity. If the current dual-compartment replanting device 208 is full, seed feeding stops, and the machine waits for a signal from the reversing valve 210 until the reversing valve fills the currently used dual compartments. When all the seeds in the replanting device 208 are used up, the dual-compartment replanting device 208 is switched again. For example, if the seeds in the No. 1 dual-compartment replanting device 208 are currently being used, the seeds are then transferred to the No. 2 dual-compartment replanting device 208. Replanting is faster than using seeds. Before the seeds in the No. 1 dual-compartment replanting device 208 are used up, the No. 2 dual-compartment replanting device 208 is already full. At this time, when the seeds in the No. 1 dual-compartment replanting device 208 are used up, the reversing valve immediately switches to the No. 2 dual-compartment replanting device 208, and then sends a signal back to control the electromagnetic three-way reversing ball valve to switch back to the No. 1 dual-compartment replanting device 208 to deliver seeds. This allows for continuous operation and ensures that there is no missed replanting.

[0037] The electronic control module of this invention uses an STM32F103 as the main control unit, and together with a power supply circuit, crystal clock circuit, reset circuit, signal conditioning circuit, drive module, and detection module, it forms a closed-loop control system. The specific workflow is as follows: After the device is started, the power supply circuit supplies power to the entire electronic control system, the crystal clock circuit provides a stable clock signal, the reset circuit ensures that the system initialization is normal, the main control unit STM32F103 completes self-test and enters standby mode, waiting for the host machine to start signal.

[0038] After the main unit starts, it sends a start signal to the main control unit. After receiving the signal, the main control unit outputs a seed metering disc control signal to drive the seed metering disc actuator to start, and the air suction seed meterer 204 begins single-seed metering operation.

[0039] During the seed fall, the near-infrared spectrometer 213 detects the seed viability. The detection signal is then processed by the signal conditioning circuit and the pulse filtering and shaping circuit before being transmitted to the main control unit.

[0040] The main control unit analyzes and judges the detection signal: if it is determined to be an unqualified seed, it immediately outputs a drive signal for the pneumatic nozzle solenoid valve to control the pneumatic nozzle actuator to fall the unqualified seed into the waste seed box body 2111 through the seed rejection guide tube 2113; if it is determined to be a qualified seed, it outputs a control signal for the seed delivery reversing valve drive circuit to instruct the electromagnetic three-way reversing ball valve 207 to switch to the corresponding channel and introduce the seed into the target dual-compartment replanting device 208.

[0041] The seed detector of the dual-compartment reseeding device 208 collects the seed status signal in the compartment in real time, and transmits it back to the main control unit after processing by its respective signal conditioning circuit. If the target dual-compartment replanting device 208 is not full of seeds, the main control unit continues to output the seed metering tray control signal, and the seed metering tray continues to supply seeds to the dual-compartment replanting device 208.

[0042] If the target dual-compartment replanting device 208 is full of seeds, the main control unit outputs a signal to stop the seed supply to the seed metering tray. The seed metering tray stops feeding seeds to the dual-compartment replanting device 208 and waits for the switching signal of the dual-compartment replanting device 208 from the reversing valve 210.

[0043] When a missed seeding occurs in the main seeding system, the main control unit receives a reseeding trigger signal, activates the seed picking direction judgment unit, and outputs a seed picking reversing valve drive signal in conjunction with the status signal of the dual-compartment reseeding device 208, controlling the reversing valve 210 to switch to the dual-compartment reseeding device 208 with sufficient seeds.

[0044] After the reversing valve 210 completes the switching, it outputs a switching signal to the main control unit. The main control unit then outputs a seed-taking signal to drive the dual-compartment replanting device 208 drive shaft controller, the dual-compartment replanting device 208 drive shaft controller, and the stepper drive module to work. This drives the seed-taking channel actuator to move and transport the qualified seeds in the corresponding dual-compartment replanting device 208 to the main seed tube 8 through the seed guide tube 209, thus completing the replanting operation.

[0045] After the reseeding operation is completed, the seed-retrieving channel actuator sends a signal to the main control unit. The main control unit then determines, based on the remaining seed quantity of the dual-compartment reseeding device 208 and the seed storage quantity of the other dual-compartment reseeding device 208, whether it is necessary to switch the seed supply dual-compartment reseeding device 208. If the seeds in the current dual-compartment replanting device 208 are not used up, and the other dual-compartment replanting device 208 is full, the current dual-compartment replanting device 208 will continue to supply seeds. If the seeds in the current dual-compartment replanting device 208 are about to run out, the main control unit will instruct the electromagnetic three-way reversing ball valve 207 to replant the empty dual-compartment replanting device 208 in advance. After the seeds in the current dual-compartment replanting device 208 are used up, the main control unit will immediately control the reversing valve 210 to switch the dual-compartment replanting device 208 to achieve continuous and uninterrupted replanting.

[0046] The two dual-compartment replanting devices 208 in the attached diagram are designated as Compartment One and Compartment Two, respectively.
