Description
Technical Field
[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a precision seeding and metering device, a seed cleaning and adjustment method, a device and a readable storage medium. Background Art
[0002] my country is a major agricultural country, with a wide variety of seed drills. Seeder mechanisms are largely similar, with most adopting finger-type and air-suction mechanisms. Crops like soybeans and corn require precise seeding. A well-designed seed drill can increase seeding speed, reduce missed and reseeded rates, and ultimately improve agricultural production efficiency and quality.
[0003] Currently, most seed metering devices use manual blade adjustment, which solves the problems of seed missed and reseeded by manually adjusting the angle of the twist wheel. Specifically, this manual adjustment method requires strict calculation of the relationship between the twist wheel slide and the movement position of the blade.
[0004] However, due to the diversity of seed particle sizes and dimensions, automatic adjustment of seed cleaning force is impossible, and manual judgment still results in significant errors. Furthermore, common seed cleaning knives are typically manufactured using an injection molding process, which is prone to wear and has a short service life, further increasing the risk of missed and reseeded seeds. Therefore, existing technologies are unable to achieve real-time, precise control in complex and changing seeding environments, making it difficult to meet the demanding seeding precision requirements of modern agriculture. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a precision seeding and metering device, a seed cleaning and adjustment method, a device and a readable storage medium.
[0006] The technical solution of the present invention to solve the above technical problems is as follows:
[0007] In a first aspect, the present application provides a precision seeding and metering device, which adopts the following technical solutions:
[0008] A precision seeding and metering device comprises a housing, an air intake pipe being provided on the housing, a sensor being provided on the outer surface of the housing, a control module, a main electric drive module, a seed tray connected to the main electric drive module and used to carry seeds, a seed clearing motor drive module, and a seed clearing module connected to the seed clearing motor drive module being provided within the housing, wherein the sensor, the main electric drive module, and the seed clearing motor drive module are all electrically connected to the control module;
[0009] The air inlet pipe is used to fill the shell with positive pressure gas, and the positive pressure gas is used to blow the seeds inside the shell onto the seed tray;
[0010] The main electric drive module is used to drive the seed disc to rotate at a predetermined speed and direction;
[0011] The sensor is used to monitor the distance between each two adjacent seeds, determine the seeding information of the seed meter based on each of the distances and preset statistical rules, the seeding information including the reseeding rate and the missed seeding rate, and send the seeding information to the control module;
[0012] The control module is used to generate an adjustment strategy for the seed-clearing motor drive module based on the seeding information of the seed-metering device and the set seeding strategy, wherein the set seeding strategy is the first seeding strategy or the second seeding strategy;
[0013] The seed cleaning motor driving module is used to adjust the position of the seed cleaning module according to the adjustment strategy, so that the seed cleaning module contacts the seeds on the seed tray and adjusts the arrangement of the seeds in the seed tray.
[0014] The beneficial effects of the present invention are: achieving intelligent control of the seed meter, capable of real-time monitoring of seed placement and dynamic adjustment of the seed clearing module through the seed clearing motor drive module, effectively reducing the seed reseeding rate and missed seeding rate, and improving seeding accuracy. Specifically, the sensor monitors the seed spacing in real time, accurately calculates the reseeding rate and missed seeding rate, and feeds this data back to the control module. The control module generates a corresponding adjustment strategy based on the preset seeding strategy, and then drives the seed clearing motor drive module to adjust the position of the seed clearing module to ensure that each hole in the seed tray has only one seed, thereby significantly improving the accuracy and efficiency of seeding.
[0015] On the basis of the above technical solution, the present invention can also be improved as follows.
[0016] Furthermore, the seed cleaning module includes a seed cleaning bracket and a seed cleaning wheel for contacting the seeds at the seed tray, one end of the seed cleaning bracket is fixedly connected to the seed cleaning wheel, and the other end of the seed cleaning bracket is rotatably connected to the housing through a connecting shaft;
[0017] The seed cleaning motor drive module includes a motor, and the output shaft of the motor is fixedly connected to a connecting component for driving the seed cleaning bracket to move.
[0018] The beneficial effect of adopting this further solution is that one end of the seed cleaning bracket is fixedly connected to the seed cleaning wheel, and the other end is rotatably connected to the housing via a connecting shaft, ensuring that the seed cleaning wheel can flexibly rotate around the connecting shaft, thereby adapting to changes in seed size and shape, and improving seed cleaning efficiency. At the same time, the motor output shaft in the seed cleaning motor drive module is fixedly connected to the connecting assembly, and the motor drives the seed cleaning bracket to move, achieving precise adjustment of the seed cleaning wheel, effectively reducing the seed reseeding rate and seed omission rate, and improving sowing accuracy.
[0019] Furthermore, the first adjustment strategy is a third adjustment strategy of controlling the motor to drive the seed cleaning wheel to adjust the first set distance in a direction close to the center of the seed disk; or a fourth adjustment strategy of controlling the motor to drive the seed cleaning wheel to adjust the second set distance in a direction away from the center of the seed disk;
[0020] When the set seeding strategy is the first seeding strategy, the control module generates an adjustment strategy processing process for the seed clearing motor drive module based on the seeding information of the seed meter and the set seeding strategy, including:
[0021] Determining whether the reseeding rate of the seed meter is greater than a set target reseeding rate;
[0022] If the reseeding rate of the seed meter is greater than the set target reseeding rate, a third control strategy is generated;
[0023] If the reseeding rate of the seed meter is not greater than the set target reseeding rate, determining whether the missed seeding rate of the seed meter is greater than the set target missed seeding rate;
[0024] If the missed seeding rate of the seed meter is greater than the set target missed seeding rate, a fourth control strategy is generated.
[0025] The beneficial effect of this further solution is that when the seed meter's reseeding rate exceeds the set target reseeding rate, the motor drives the seed clearing wheel to adjust a first set distance closer to the center of the seed disc to reduce the reseeding rate. When the seed meter's reseeding rate is not greater than the target reseeding rate but the missed seed rate is greater than the target missed seed rate, the motor drives the seed clearing wheel to adjust a second set distance away from the center of the seed disc to reduce the missed seed rate. This method allows for real-time and precise adjustment of the seed clearing wheel position, effectively reducing both the missed seed rate and the missed seed rate, and improving seeding accuracy.
[0026] Furthermore, the second adjustment strategy is a fifth adjustment strategy of controlling the motor to drive the seed cleaning wheel to adjust the third set distance in a direction away from the center of the seed disk; or a sixth adjustment strategy of controlling the motor to drive the seed cleaning wheel to adjust the fourth set distance in a direction close to the center of the seed disk;
[0027] When the set seeding strategy is the second seeding strategy, the control module generates a processing process of the adjustment strategy of the seed clearing motor drive module based on the seeding information of the seed meter and the set seeding strategy, including:
[0028] Determining whether the missed seeding rate of the seed meter is greater than a set target missed seeding rate;
[0029] If the missed seeding rate of the seed meter is greater than the set target missed seeding rate, a fifth adjustment strategy is generated;
[0030] If the missed seeding rate of the seed meter is not greater than the set target missed seeding rate, determining whether the reseeding rate of the seed meter is greater than the set target reseeding rate;
[0031] If the reseeding rate of the seed meter is greater than the set target reseeding rate, a sixth adjustment strategy is generated.
[0032] The beneficial effect of this further solution is that when the seed meter's missed seeding rate exceeds the set target missed seeding rate, the motor drives the seed clearing wheel to adjust a third set distance away from the center of the seed disc to reduce the missed seeding rate. When the missed seeding rate is within the target missed seeding rate but the reseeding rate is greater than the target reseeding rate, the motor drives the seed clearing wheel to adjust a fourth set distance closer to the center of the seed disc to reduce the reseeding rate. This enables real-time and precise control of the seed clearing function, improves seeding accuracy, and reduces the risk of missed seeding and reseeding.
[0033] Furthermore, the connecting assembly includes a driving gear and a rack, the driving gear is fixedly connected to the output shaft of the motor, the rack is fixedly connected to the seed cleaning bracket, and the driving gear is meshed with the rack.
[0034] The beneficial effect of adopting this further solution is that the coordination of the drive gear and rack enables precise control of the movement trajectory of the seed cleaning wheel, ensuring that the wheel moves along a predetermined path driven by the motor. This allows for accurate adjustment of the distance between the seed cleaning wheel and the seed tray, effectively reducing the reseeding and missed seeding rates and improving seeding accuracy. Specifically, the fixed connection between the drive gear and the motor output shaft ensures the stability and reliability of power transmission; the fixed connection between the rack and the seed cleaning bracket enables the bracket to move smoothly under the drive gear, achieving precise positioning of the seed cleaning wheel. This mechanical structure not only improves the efficiency of the seed cleaning mechanism, but also extends its service life and reduces maintenance costs.
[0035] Furthermore, the connecting assembly includes a cam, which is fixedly connected to the output shaft of the motor, and a cam groove adapted to the cam is provided on the seed cleaning bracket. The cam is fixedly connected to a connecting rod with one end inserted into the cam groove on the side away from the motor output shaft, and the seed cleaning bracket is connected to a torsion spring for driving the seed cleaning bracket to rotate around the connecting shaft.
[0036] The beneficial effects of adopting this further solution include: a cam is fixedly connected to the motor output shaft, a cam slot on the seed cleaning bracket is adapted to the cam, and the cam is inserted into the cam slot via a connecting rod. A torsion spring is also connected to the seed cleaning bracket, so that when the motor drives the cam to rotate, its output shaft also drives the cam to rotate. The rotation of the cam causes its profile to move along the cam slot on the seed cleaning bracket, pushing or pulling the seed cleaning bracket to move via the connecting rod. During the movement of the seed cleaning bracket, the torsion spring is compressed or stretched. The motor and torsion spring control the movement and stopping position of the cam and the moving seed cleaning bracket, not only achieving precise positioning of the seed cleaning wheel, but also effectively reducing mechanical wear and increasing the service life of the seed cleaning module. Furthermore, the torsion spring ensures that the seed cleaning bracket remains stable in the absence of external forces, further improving the reliability and stability of the seed cleaning effect.
[0037] Furthermore, the seed cleaning plate is provided with a plurality of plate holes, and the plurality of plate holes are evenly distributed around a circle concentric with the seed cleaning plate;
[0038] The beneficial effect of adopting the above further solution is that the multiple holes on the seed cleaning plate are evenly distributed around the circumference of the circle concentric with the seed cleaning plate, ensuring that each hole can accurately receive a seed, thereby improving the seed distribution uniformity and sowing accuracy.
[0039] In a second aspect, the present application provides a seed clearing adjustment method for a precision seeding and metering device, which adopts the following technical solutions:
[0040] A seed clearing adjustment method for a precision seeding and metering device, comprising:
[0041] Acquire seeding information of the seed meter sent by the sensor, wherein the seeding information includes a reseeding rate and a missed seeding rate;
[0042] Based on the seeding information of the seed meter and the set seeding strategy, an adjustment strategy of the seed clearing motor drive module is generated, wherein the set seeding strategy is the first seeding strategy or the second seeding strategy;
[0043] The adjustment strategy is sent to the seed clearing motor drive module, so that the seed clearing motor drive module adjusts the position of the seed clearing module based on the adjustment strategy, so that the seed clearing module contacts the seeds on the seed tray, and adjusts the arrangement of the seeds in the seed tray.
[0044] In a third aspect, the present application provides an electronic device, which adopts the following technical solution:

DETAILED DESCRIPTION
[0056] The present application is further described in detail below with reference to the accompanying drawings.
[0057] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0058] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.
[0059] The embodiment of the present application provides a precision seeding device, such as Figure 1 and Figure 2 As shown, the seed metering device includes a shell 4, an air intake pipe 6 is provided on the shell 4, a sensor 7 is provided on one side of the shell 4, and a control module 8, a main electric drive module 5, a seed tray 3 for carrying seeds connected to the main electric drive module 5, a seed cleaning motor drive module 1 and a seed cleaning module 2 connected to the seed cleaning motor drive module 1 are provided in the shell 4. The sensor 7, the main electric drive module 5 and the seed cleaning motor drive module 1 are all electrically connected to the control module 8;
[0060] The air inlet pipe 6 is used to fill the housing 4 with positive pressure gas, and the positive pressure gas is used to blow the seeds inside the housing 4 onto the seed tray 3;
[0061] The main electric drive module 5 is used to drive the seed disc 3 to rotate at a predetermined speed and direction;
[0062] The sensor 7 is used to monitor the distance between each two adjacent seeds, determine the seeding information of the seed meter based on each distance and preset statistical rules, the seeding information includes the reseeding rate and the missed seeding rate, and send the seeding information to the control module 8;
[0063] The control module 8 is used to generate an adjustment strategy for the seed-clearing motor drive module 1 based on the seeding information of the seed-metering device and the set seeding strategy, wherein the set seeding strategy is the first seeding strategy or the second seeding strategy;
[0064] The seed cleaning motor driving module 1 is used to adjust the position of the seed cleaning module 2 according to the adjustment strategy, so that the seed cleaning module 2 contacts the seeds on the seed tray 3 and adjusts the arrangement of the seeds in the seed tray 3.
[0065] The seed metering device is filled with positive-pressure gas through an air inlet pipe 6. The seeds in the precision seed metering device are blown into the holes in the seed tray 3. The main electric drive module 5 drives the seed tray 3 to rotate at a predetermined speed and direction, allowing the seed cleaning module 2 to contact the seeds in the seed tray 3 and remove excess seeds. During the seeding process, the sensor 7 monitors the spacing between two adjacent seeds. Based on each spacing and preset statistical rules, the reseeding rate and missed seeding rate of the seed metering device are calculated in real time, and this data is fed back to the control module 8. The control module 8 generates a corresponding adjustment strategy based on the preset seeding strategy, and then drives the seed cleaning motor drive module 1 to adjust the position of the seed cleaning module 2 to ensure that only one seed is placed in each hole in the seed tray 3. This achieves intelligent control of the seed metering device, capable of real-time monitoring of seed placement and dynamic adjustment of the seed cleaning module 2 through the seed cleaning motor drive module 1, effectively reducing the seed reseeding rate and missed seeding rate, and improving seeding accuracy and efficiency.
[0066] In one embodiment, specifically, the seed cleaning disc 3 is provided with a plurality of disc holes, and the plurality of disc holes are evenly distributed around a circle concentric with the seed cleaning disc 3;
[0067] The sensor 7 is a photoelectric sensor, which is installed on one side of the housing 4 and opposite to the seed discharge port of the seed tray 3.
[0068] The sensor 7 determines the seeding information of the seed meter based on the respective spacings and preset statistical rules, mainly including:
[0069] Compare each spacing with a preset first target spacing, take the number of sowings corresponding to a spacing not greater than the first target spacing as the number of reseedings, and determine the reseeding rate of the seed meter based on all the reseedings and the target number of sowings;
[0070] Each spacing is compared with a preset second target spacing, and the number of sowings corresponding to a spacing not less than the second target spacing is regarded as the number of missed sowings. Based on all the missed sowings and the target sowings, the missed sowing rate of the seed meter is determined; wherein the second target spacing is greater than the first target spacing.
[0071] In one embodiment, specifically, Figure 3 As shown, the seed cleaning module 2 includes a seed cleaning bracket 22 and a seed cleaning wheel 21 for contacting the seeds on the seed tray 3. One end of the seed cleaning bracket 22 is fixedly connected to the seed cleaning wheel 21, and the other end of the seed cleaning bracket 22 is rotatably connected to the housing 4 via a connecting shaft 9. The seed cleaning motor drive module 1 includes a motor 11, and the output shaft of the motor 11 is fixedly connected to a connecting assembly 12 for driving the seed cleaning bracket 22 to move.
[0072] The seed cleaning wheel 21 is made of high-strength wear-resistant materials, such as carbon steel or stainless steel, to increase its service life. The surface of the seed cleaning wheel 21 can be polished to reduce friction with the seeds and prevent seed damage. The seed cleaning bracket 22 can be made of lightweight aluminum alloy material to reduce the weight of the entire seed cleaning module 2 and improve the response speed. The seed cleaning bracket 22 and the seed cleaning wheel 21 can be fixedly connected by bolts for easy disassembly and replacement. The connecting shaft 9 adopts high-precision bearings to ensure that the seed cleaning bracket 22 is smooth and free of jams during rotation. Dust covers can be set at both ends of the connecting shaft 9 to prevent dust from entering and affecting the rotation performance. The length of the connecting shaft 9 can be adjusted according to actual needs to adapt to different models of seed meters.
[0073] One end of the seed cleaning bracket 22 is fixedly connected to the seed cleaning wheel 21, and the other end is rotatably connected to the housing 4 via the connecting shaft 9, ensuring that the seed cleaning wheel 21 can flexibly rotate around the connecting shaft 9, thereby adapting to changes in seed size and shape, and improving the seed cleaning effect. At the same time, the output shaft of the motor 11 in the seed cleaning motor drive module 1 is fixedly connected to the connecting component 12. The motor 11 drives the seed cleaning bracket 22 to move, achieving precise adjustment of the seed cleaning wheel 21, effectively reducing the seed re-seeding rate and missed seeding rate, and improving sowing accuracy.
[0074] As an optional embodiment of the connecting assembly 12, the connecting assembly 12 includes a drive gear 121 and a rack 122. The drive gear 121 is fixedly connected to the output shaft of the motor 11, and the rack 122 is fixedly connected to the seed cleaning bracket 22. The drive gear 121 and the rack 122 mesh with each other. The modules and pressure angles of the drive gear 121 and the rack 122 must match to ensure transmission efficiency and stability. Guide grooves can be provided on both sides of the rack 122 to ensure that the rack 122 maintains linear motion during movement and prevents deviation.
[0075] The fixed connection between the drive gear 121 and the output shaft of the motor 11 ensures the stability and reliability of power transmission. The fixed connection between the rack 122 and the seed cleaning bracket 22 enables the seed cleaning bracket 22 to move smoothly under the drive of the drive gear 121, thereby achieving precise positioning of the seed cleaning wheel 21. This ensures that the seed cleaning wheel 21 moves along a predetermined path under the drive of the motor 11, and thus accurately adjusts the distance between the seed cleaning wheel 21 and the seed tray 3, effectively reducing the reseeding rate and the missed seeding rate of seeds and improving sowing accuracy.
[0076] As another optional embodiment of the connection component 12, Figure 4As shown, the connecting assembly 12 includes a cam 123, which is fixedly connected to the output shaft of the motor 11. A cam groove 23 adapted to the cam 123 is provided on the seed cleaning bracket 22. The cam 123 is fixedly connected to a connecting rod with one end inserted into the cam groove 23 on one side away from the output shaft of the motor 11. The seed cleaning bracket 22 is connected to a torsion spring 24 for driving the seed cleaning bracket 22 to rotate around the connecting shaft 9.
[0077] The profile curve of the cam 123 can be designed according to actual needs to achieve different motion trajectories. The shape and size of the cam groove 23 need to match the profile curve of the cam 123 to ensure that the seed cleaning bracket 22 is stable and free of jams during movement.
[0078] The cam 123 is fixedly connected to the output shaft of the motor 11, and the cam groove 23 provided on the seed cleaning bracket 22 is adapted to the cam 123. The cam 123 is inserted into the cam groove 23 through a connecting rod. At the same time, the seed cleaning bracket 22 is connected to a torsion spring 24, so that when the motor 11 drives the cam 123 to rotate, its output shaft will drive the cam 123 to rotate. The rotation of the cam 123 will cause its profile to move along the cam groove 23 on the seed cleaning bracket 22, and push or pull the seed cleaning bracket 22 to move through the connecting rod. During the movement of the seed cleaning bracket 22, the torsion spring 24 will be compressed or stretched. The movement and stop position of the cam 123 and the dynamic seed cleaning bracket 22 are controlled by the motor 11 and the torsion spring 24, which can not only achieve accurate positioning of the seed cleaning wheel 21, but also effectively reduce mechanical wear and improve the service life of the seed cleaning module 2.
[0079] It should be noted that the connection component 12 transmitting power from the motor 11 to the seed cleaning wheel 21 is not limited to the gear rack 122 and cam 123 movement structure, and other movement modes can also be realized, such as crank slider, belt drive or chain drive structure, but is not limited to this.
[0080] In one embodiment, the first adjustment strategy is a third adjustment strategy of controlling the motor 11 to drive the seed cleaning wheel 21 to adjust the first set distance in a direction close to the center of the seed disk 3; or a fourth adjustment strategy of controlling the motor 11 to drive the seed cleaning wheel 21 to adjust the second set distance in a direction away from the center of the seed disk 3;
[0081] When the set seeding strategy is the first seeding strategy, the control module 8 generates the adjustment strategy processing process of the seed clearing motor driving module 1 based on the seeding information of the seed meter and the set seeding strategy, including:
[0082] Determining whether the reseeding rate of the seed meter is greater than a set target reseeding rate;
[0083] If the reseeding rate of the seed meter is greater than the set target reseeding rate, a third control strategy is generated;
[0084] If the reseeding rate of the seed meter is not greater than the set target reseeding rate, determining whether the missed seeding rate of the seed meter is greater than the set target missed seeding rate;
[0085] If the missed seeding rate of the seed meter is greater than the set target missed seeding rate, a fourth control strategy is generated.
[0086] In the above embodiment, multiple seeding strategies are pre-designed, namely, a first seeding strategy and a second seeding strategy. The first seeding strategy is a strategy that is manually selected to prioritize a low replay rate, and the second seeding strategy is a strategy that is manually selected to prioritize a low missed broadcast rate.
[0087] If the seeding strategy selected by the user is the first seeding strategy, the control module 8 first determines whether the reseeding rate of the seeding device is greater than the set target reseeding rate. When the reseeding rate of the seeding device is greater than the set target reseeding rate, the motor 11 drives the seed cleaning wheel 21 to adjust the first set distance closer to the center of the seed disc 3 to reduce the reseeding rate.
[0088] Afterwards, it is determined whether the missed seeding rate of the seed meter is greater than the set target missed seeding rate. When the missed seeding rate of the seed meter is not greater than the target missed seeding rate, the motor 11 drives the seed cleaning wheel 21 to adjust the second set distance away from the center of the seed disc 3 to reduce the missed seeding rate. When the missed seeding rate of the seed meter is not greater than the target missed seeding rate, the motor 11 does not operate.
[0089] In one embodiment, the second adjustment strategy is a fifth adjustment strategy of controlling the motor 11 to drive the seed cleaning wheel 21 to adjust the third set distance in a direction away from the center of the seed disk 3; or a sixth adjustment strategy of controlling the motor 11 to drive the seed cleaning wheel 21 to adjust the fourth set distance in a direction close to the center of the seed disk 3;
[0090] When the set seeding strategy is the second seeding strategy, the process of generating the adjustment strategy of the seed-clearing motor driving module 1 based on the seeding information of the seed meter and the set seeding strategy includes:
[0091] Determining whether the missed seeding rate of the seed meter is greater than a set target missed seeding rate;
[0092] If the missed seeding rate of the seed meter is greater than the set target missed seeding rate, a fifth adjustment strategy is generated;
[0093] If the missed seeding rate of the seed meter is not greater than the set target missed seeding rate, determining whether the reseeding rate of the seed meter is greater than the set target reseeding rate;
[0094] If the reseeding rate of the seed meter is greater than the set target reseeding rate, a sixth adjustment strategy is generated.
[0095] In the above embodiment, if the seeding strategy selected by the user is the second seeding strategy, the control module 8 first determines whether the missed seeding rate of the seed meter is greater than the set target missed seeding rate. When the missed seeding rate of the seed meter is greater than the set target missed seeding rate, the motor 11 drives the seed cleaning wheel 21 to adjust the third set distance away from the center of the seed disc 3 to reduce the missed seeding rate.
[0096] Afterwards, it is determined whether the reseeding rate of the seed meter is greater than the set target reseeding rate. If the reseeding rate is greater than the target reseeding rate, the motor 11 drives the seed cleaning wheel 21 to adjust the fourth set distance closer to the center of the seed disc 3 to reduce the reseeding rate. If the reseeding rate of the seed meter is not greater than the target reseeding rate, the motor 11 does not operate.
[0097] Based on Figure 1 The present invention also provides a method for adjusting the seeding of a precision seeding device based on the same principle as the seeding device shown in FIG. Figure 5 The seed clearing adjustment method of the precision seeding device mainly includes:
[0098] Step S101, obtaining the seeding information of the seed meter sent by the sensor, wherein the seeding information includes a reseeding rate and a missed seeding rate;
[0099] Step S102, generating an adjustment strategy for a seed-clearing motor drive module based on the seeding information of the seed-metering device and a set seeding strategy, wherein the set seeding strategy is a first seeding strategy or a second seeding strategy;
[0100] Step S103: sending the adjustment strategy to the seed clearing motor driving module, so that the seed clearing motor driving module adjusts the position of the seed clearing module based on the adjustment strategy, so that the seed clearing module contacts the seeds on the seed tray, and adjusts the arrangement of the seeds in the seed tray.
[0101] It should be noted that the execution body of this method can be a control module, and its implementation principle is the same as that of the hardcover seed metering device described above, which will not be repeated here.
