[0002] my country is a large agricultural country with a wide variety of seed drills. The seed drill mechanisms are similar, mostly finger-clip and air-suction types. Crops such as soybeans and corn require precision seeding. A reasonable design of the seed drill can increase the seeding speed, reduce the missed seed rate and reseeding rate, and thus improve agricultural production efficiency and quality.

[0003] At present, the seed cleaning knife of the seed metering device is mostly manual, and the position of the seed cleaning knife is adjusted by manually adjusting the angle of the twist wheel to solve the problem of seed missing and reseeding. Specifically, this manual adjustment method requires strict calculation of the relationship between the twist wheel slide rail and the moving position of the seed cleaning knife.

[0004] However, due to the diversity of seed particle size and external dimensions, it is impossible to automatically adjust the seed cleaning force, and there are still large errors in manual judgment operations. In addition, common seed cleaning knives are usually manufactured using injection molding processes, which are easy to wear and have a short service life, further increasing the risk of missed sowing and reseeding. Therefore, when dealing with complex and changeable sowing environments, the existing technology cannot achieve real-time and precise control, and it is difficult to meet the requirements of modern agriculture for sowing accuracy. 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:

[0009] Wherein, 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 plate;

[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 every two adjacent seeds, determine the seeding information of the seed meter based on each of the distances and preset statistical rules, the seeding information includes a reseeding rate and a 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 arranges and adjusts the seeds in the seed tray.

[0014] The beneficial effects of the present invention are: realizing intelligent control of the seed metering device, being able to monitor the seeding situation of the seeds in real time and drive the seed clearing module to make dynamic adjustments through the seed clearing motor drive module, effectively reducing the seed reseeding rate and missed seeding rate, and improving the sowing accuracy. Specifically, the seed spacing is monitored in real time by the sensor, the reseeding rate and missed seeding rate are accurately counted, and these data are fed back to the control module. The control module generates a corresponding adjustment strategy according to 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 sowing.

[0015] Based on the above technical solution, the present invention can also be improved as follows.

[0017] The seed cleaning motor driving module comprises a motor, and an output shaft of the motor is fixedly connected with a connecting component for driving the seed cleaning bracket to move.

[0018] The beneficial effect of adopting the above further scheme 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 through a connecting shaft, ensuring that the seed cleaning wheel can flexibly rotate around the connecting shaft, thereby adapting to changes in different seed sizes and shapes and improving the seed cleaning effect. At the same time, the motor output shaft in the seed cleaning motor drive module is fixedly connected to a connecting component, and the seed cleaning bracket is driven by the motor to move, so as to achieve precise adjustment of the seed cleaning wheel, effectively reducing the reseeding rate and missed seeding rate of seeds and improving the sowing accuracy.

[0019] Further, 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 the adjustment strategy processing process of the seed clearing motor drive module based on the seeding information of the seeding device and the set seeding strategy, including:

[0021] Determining whether the reseeding rate of the seed metering device 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.

This method can accurately adjust the position of the seed cleaning wheel in real time, effectively reduce the reseeding rate and missed seeding rate, and improve sowing accuracy.

[0026] Further, 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 driving module based on the seeding information of the seeding device 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;

[0031] If the reseeding rate of the seed meter is greater than the set target reseeding rate, a sixth adjustment strategy is generated.

[0034] The beneficial effect of adopting the above further scheme is: by utilizing the cooperation of the driving gear and the rack, the movement trajectory of the seed cleaning wheel can be accurately controlled to ensure that the seed cleaning wheel moves along the predetermined path under the drive of the motor, and then the distance between the seed cleaning wheel and the seed disc is accurately adjusted, effectively reducing the reseeding rate and missed seeding rate of seeds, and improving the sowing accuracy. Specifically, the fixed connection between the driving 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 seed cleaning bracket to move smoothly under the drive of the driving gear, thereby realizing the precise positioning of the seed cleaning wheel. This mechanical structure not only improves the working efficiency of the seed cleaning mechanism, but also extends the 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 effect of adopting the above further scheme is: the cam is fixedly connected with the motor output shaft, the cam groove provided on the seed cleaning bracket is adapted to the cam, the cam is inserted into the cam groove through the connecting rod, and the seed cleaning bracket is connected with a torsion spring, so that when the motor drives the cam to rotate, its output shaft will drive the cam to rotate. The rotation of the cam will cause its contour to move along the cam groove on the seed cleaning bracket, and push or pull the seed cleaning bracket to move through the connecting rod. During the movement of the seed cleaning bracket, the torsion spring will be compressed or stretched. The movement and stop position of the cam and the moving seed cleaning bracket are controlled by the motor and the torsion spring, which can not only realize the precise positioning of the seed cleaning wheel, but also effectively reduce mechanical wear and increase the service life of the seed cleaning module.

[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 every two adjacent seeds, determine the seeding information of the seed meter based on each of the distances 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-seeding 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 arranges and adjusts the seeds in the seed tray 3 .

[0065] The seeding device is filled with positive pressure gas through the air inlet pipe 6, and the seeds in the precision seeding device are blown into the holes of the seed tray 3. The main electric drive module 5 drives the seed tray 3 to rotate at a predetermined speed and direction, so that the seed cleaning module 2 contacts the seeds in the seed tray 3, and can clean out excess seeds. During the seeding process of the seeding device, the distance between two adjacent seeds is monitored by the sensor 7, and the reseeding rate and missed seeding rate of the seeding device are calculated in real time based on each of the distances and the preset statistical rules, and these data are fed back to the control module 8. The control module 8 generates a corresponding adjustment strategy according to 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 there is only one seed in each hole of the seed tray 3. Intelligent control of the seeding device is realized, and the seeding situation of the seeds can be monitored in real time and the seed cleaning module 2 can be driven by the seed cleaning motor drive module 1 for dynamic adjustment, which effectively reduces the seed reseeding rate and missed seeding rate, and improves the sowing accuracy and efficiency.

[0066] In one embodiment, specifically, the seed cleaning disk 3 is provided with a plurality of disk holes, and the plurality of disk holes are evenly distributed around a circle cocentric with the seed cleaning disk 3;

[0067] The sensor 7 is a photoelectric sensor, which is installed on one side of the housing 4 and is 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 each of the spacings and preset statistical rules, mainly including:

[0069] Compare each spacing with a preset first target spacing, take the sowing times corresponding to the spacing not greater than the first target spacing as the number of reseeding times, and determine the reseeding rate of the seed meter based on all the number of reseeding times and the target number of sowing times;

[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 missed sowings and the target sowing times, 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 at 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 through 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 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 stable 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 seeding devices.

[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 through the connecting shaft 9, ensuring that the seed cleaning wheel 21 can flexibly rotate around the connecting shaft 9, thereby adapting to the changes in different seed sizes and shapes 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 with the connecting component 12, and the seed cleaning bracket 22 is driven to move by the motor 11 to achieve precise adjustment of the seed cleaning wheel 21, effectively reducing the reseeding rate and missed seeding rate of seeds and improving the sowing accuracy.

[0074] As an optional embodiment of the connecting assembly 12, the connecting assembly 12 includes a driving gear 121 and a rack 122, wherein the driving gear 121 is fixedly connected to the output shaft of the motor 11, the rack 122 is fixedly connected to the seed cleaning bracket 22, and the driving gear 121 is meshed with the rack 122. The module and pressure angle of the driving gear 121 and the rack 122 need to match to ensure transmission efficiency and stability. Guide grooves can be set on both sides of the rack 122 to ensure that the rack 122 maintains linear motion during movement to avoid deviation.

[0075] The fixed connection between the driving 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 driving gear 121, thereby realizing the precise positioning of the seed cleaning wheel 21. It ensures that the seed cleaning wheel 21 moves along a predetermined path under the drive of the motor 11, and then accurately adjusts the distance between the seed cleaning wheel 21 and the seed tray 3, effectively reducing the reseeding rate and missed seeding rate of seeds, and improving the sowing accuracy.

[0076] As another optional embodiment of the connection component 12, Figure 4As shown, the connecting component 12 includes a cam 123, and the cam 123 is fixedly connected to the output shaft of the motor 11. A cam groove 23 adapted to the cam 123 is opened 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, the cam groove 23 provided on the seed cleaning bracket 22 is adapted to the cam 123, and 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 with 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 moving seed cleaning bracket 22 are controlled by the motor 11 and the torsion spring 24, which can not only realize the precise 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 assembly 12 that transmits power from the motor 11 to the seed cleaning wheel 21 is not limited to the gear rack 122 and cam 123 motion structure, and other motion 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 seeding device and the set seeding strategy, including:

[0082] Determining whether the reseeding rate of the seed metering device 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 implementation, multiple seeding strategies are pre-designed, namely, a first seeding strategy and a second seeding strategy. The first seeding strategy is a strategy that manually selects to prioritize low replay rates, and the second seeding strategy is a strategy that manually selects to prioritize low missed broadcast rates.

[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 close 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 seeding device 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 implementation, 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 seeding device is greater than the set target missed seeding rate. When the missed seeding rate of the seeding device 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 metering device is greater than the set target reseeding rate. When 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 to the center of the seed disc 3 to reduce the reseeding rate. When the reseeding rate of the seed metering device is not greater than the target reseeding rate, the motor 11 does not act.

[0097] Based on Figure 1 The present invention also provides a method for adjusting the seed clearing 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 a precision seeding and metering device mainly includes:

[0098] Step S101, obtaining the seeding information of the seeding device 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 cleaning motor driving module, so that the seed cleaning motor driving module adjusts the position of the seed cleaning module based on the adjustment strategy, so that the seed cleaning module contacts the seeds on the seed tray, and arranges and adjusts the seeds in the seed tray.

[0101] It should be noted that the execution body of the method may 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.
