Description

Technical Field

[0001] This invention relates to the field of seeding technology, and in particular to a method for adjusting the amount of seeds taken and fed, and a seeder using the same method. Background Technology

[0002] Currently, the existing seed sowing method mainly uses a roller seeder. Specifically, the roller seeder has a seed-collecting mechanism consisting of a seed-collecting hole, a seed inlet, and a seed-feeding channel. It also has a seed storage chamber and a seed outlet. The seed-collecting mechanism collects and distributes seeds as the roller seeder rotates. During the seed collection process in the seed-feeding area, two or more seeds in the seed storage chamber enter the seed-collecting hole through the seed-feeding channel. Then, other excess seeds are filtered and removed. As the roller seeder rotates, the seeds in the seed-collecting hole are discharged in the seed-feeding area, thus completing the sowing process.

[0003] However, in existing seed sowing methods, during the seed-collecting process, the seed-collecting hole can collect two or more seeds in one seed-collecting cycle, and the size of the seeds varies. During the rolling of the roller seeder, the posture and movement direction of the seeds stored in the seed storage chamber are chaotic, resulting in an uncertain number of seeds that can enter the seed-collecting hole, and an uncertain number of seeds that are sown each time, which in turn leads to uneven seedling emergence in the later stage.

[0004] Furthermore, existing seed sowing methods are not convenient for adjusting the seed quantity according to the different seed requirements of different sowing lands. Moreover, existing seed sowing methods can only adjust the seed quantity of the roller seeder by changing the size of the seed-collecting hole to adjust the number of seeds collected by the seed-collecting hole. However, this method of adjusting the seed quantity of the roller seeder requires disassembling the entire roller seeder and replacing it with a seed-collecting mechanism with a seed-collecting hole of suitable size, which makes the modification of the roller seeder for adjusting the seed quantity difficult and labor-intensive.

[0005] Furthermore, in existing seed sowing methods, during the seed collection process, two or more seeds from the seed storage chamber can simultaneously enter the seed inlet channel. This mutual compression of multiple seeds can easily cause blockages in the inlet channel, preventing seeds from entering the seed collection hole and resulting in seed shortages and subsequent seedling loss. Therefore, there is an urgent need for a method that facilitates the adjustment of seed collection and sowing rates and allows for precise seed collection and sowing. Summary of the Invention

[0006] The purpose of this invention is to overcome at least one deficiency of the prior art and to provide a method for adjusting the amount of seeds taken and planted that is easy to adjust and can accurately perform seed taking and planting. In addition, a seeder is also provided.

[0007] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A method for adjusting the quantity of seeds taken and sown, comprising:

[0008] A seeder is used to pick up and plant seeds. The seeder includes a roller assembly, and the roller assembly has a seed storage cavity for storing seeds.

[0009] The roller assembly has multiple seed-picking structures spaced circumferentially along its inner side surface for picking, storing, and dispensing seeds stored in the seed storage cavity. Each seed-picking structure has multiple seed-picking holes spaced axially along the roller assembly. Each seed-picking hole can hold one seed. During the rolling of the roller assembly, a seed-feeding area, a seed-storing area, and a seed-dispensing area are formed within the roller assembly.

[0010] Based on the seed quantity requirements of the land to be sown, the on / off state of several seed-taking holes in multiple seed-taking holes on each seed-taking structure is controlled to restrict seed intake, ensuring that each seed-taking structure has a suitable number of seed-taking holes for seed taking, storing, and dispensing. The number of seeds that each seed-taking structure can take out and dispense in each seed-taking and dispensing cycle is adjusted. An appropriate amount of seeds is stored in the seed storage cavity, and the roller assembly is driven to rotate. During the rotation of the roller assembly, the seed-taking structure takes out and dispenses a certain number of seeds in each seed-taking and dispensing cycle.

[0011] The beneficial effects of this invention are as follows: The seed-taking and sowing quantity adjustment method in this embodiment utilizes a seed-taking hole within the seeder that can hold one seed, which helps ensure that each seed-taking hole holds only one seed in the sowing area, thereby ensuring that only one seed is discharged from each seed-taking hole in the sowing area. Furthermore, the number of seed-taking holes on each seed-taking structure is determined, and the opening and closing states of several seed-taking holes among the multiple seed-taking holes on each seed-taking structure are controlled to limit the sowing quantity, ensuring that each seed-taking hole... Each seed collection structure has a suitable number of seed collection pits for seed collection, storage, and dispensing. This allows for adjustment of the number of seeds collected by each seed collection structure in a seed collection cycle, thereby regulating the number of seeds dispensed by the seeder in each dispensing cycle. Each seed collection structure collects a specific number of seeds in a seed collection cycle and dispenses a specific number of seeds in a dispensing cycle, thus achieving precise seed collection and dispensing. This allows for adjustment of the seed dispensing amount to meet the different seed dispensing requirements of different lands to be sown, and the method of adjusting the seed dispensing amount is simple and easy to implement.

[0012] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0013] According to one embodiment of the present invention, the on / off state of several seed-taking holes among a plurality of seed-taking holes on each seed-taking structure is controlled to achieve seed intake restriction, so that each seed-taking structure has an equal number of seed-taking holes for seed taking, storing and feeding.

[0014] In the seed collection and sowing quantity adjustment method of this embodiment, after imposing a seed intake restriction on the seed collection holes on each seed collection structure, each seed collection structure has an equal number of seed collection holes for seed collection, storage and sowing. This is beneficial for each seed collection structure to take out an equal number of seeds in one seed collection cycle and sow an equal number of seeds in one sowing cycle, thereby achieving precise seed collection and sowing, and also facilitating uniform sowing.

[0015] According to one embodiment of the present invention, the method for adjusting the quantity of seeds taken and sown further includes:

[0016] The roller assembly has multiple seed outlets spaced circumferentially on its wheel surface. Each of the multiple seed outlets is connected to the seed storage cavity. Multiple seed taking structures are installed on the inner wheel surface of the roller assembly, corresponding to the seed outlets circumferentially, and are located in the seed storage cavity.

[0017] On the outer wheel surface of the roller assembly, there are multiple seed-infeeding mechanisms corresponding to the multiple seed discharge outlets for inserting seeds discharged from the seed discharge outlets into the soil. Each seed-infeeding mechanism has a seed transmission channel that communicates with the seed discharge outlet. During the rolling of the roller assembly, in the seed-infeeding area, the seeds stored in the seed-taking hole on the seed-taking structure located in the seed-infeeding area are discharged from the seed discharge outlet and enter the soil through the seed transmission channel.

[0018] In this embodiment, the seed picking and sowing quantity adjustment method has multiple seed-insertion mechanisms connected to the outer wheel surface of the roller assembly. This facilitates the insertion of seeds into the soil through the seed-insertion mechanisms, thereby ensuring that the position and depth of the seeds in the soil are suitable and improving the uniformity of seed distribution after insertion. This is beneficial for reasonable dense planting and increasing yield.

[0019] According to one embodiment of the present invention, the method for adjusting the quantity of seeds taken and sown further includes:

[0020] The roller assembly is equipped with multiple seed posture adjustment structures corresponding to the seed picking structure. These seed posture adjustment structures are circumferentially rotated and installed in the seed storage cavity, close to the seed picking structure along the axial direction of the roller assembly. Each seed posture adjustment structure has multiple seed posture adjustment slots corresponding to the seed picking holes on the side facing the seed picking structure. The seed posture adjustment slots are open on the side facing the seed picking structure, and their contours are adapted to the shape of the seeds. Each seed posture adjustment slot can adjust the posture of the seeds close to it and sequentially accommodate and face the open seed picking hole with a seed whose posture is adapted to the seed posture adjustment slot.

[0021] By providing a swing drive mechanism on the roller assembly, the seed posture adjustment structure is connected to the swing drive mechanism, allowing the seed posture adjustment structure to swing relative to the seed picking structure under the drive of the swing drive mechanism. During the rolling of the roller assembly, in the seed feeding area, the posture of the seeds close to it is adjusted by the seed posture adjustment groove, and the seeds whose posture matches the seed posture adjustment groove enter the seed posture adjustment groove of the seed posture adjustment structure located in the seed feeding area. In the seed storage area, the seeds that have entered the seed posture adjustment groove enter and are stored in the seed picking hole of the seed picking structure located in the seed storage area, which is in an open state. In the seed delivery area, the seeds stored in the seed picking hole are delivered from the seed picking hole of the seed picking structure located in the seed delivery area and discharged through the seed discharge outlet.

[0022] In this embodiment, the seed picking and sowing quantity adjustment method has multiple seed posture adjustment slots corresponding to multiple seed picking holes on the seed posture adjustment structure. Driven by a swing drive mechanism, the seed posture adjustment structure swings relative to the seed picking structure, causing the seeds near the seed posture adjustment slots to adjust their posture. This facilitates the adaptation of the seed posture of the seeds near the slots to the appropriate slots, allowing them to enter the seed picking holes smoothly and preventing seed shortages in open seed picking holes. Furthermore, each seed posture adjustment slot can only accommodate and allow one seed with a posture adapted to it, preventing multiple seeds from being squeezed into the slot simultaneously and causing blockages. This further improves the accuracy of seed picking and sowing by the seeder.

[0023] According to an embodiment of the present invention, the seed picking and feeding quantity adjustment method further includes: providing a plurality of elastic blocking structures corresponding one-to-one with the seed posture adjustment structure in the roller assembly; one end of the elastic blocking structure is connected to the outside of the seed posture adjustment structure, and the other end of the elastic blocking structure extends to the outer port of the seed posture adjustment groove and blocks the outside of the seed posture adjustment groove; during the process of driving the roller assembly to roll, in the seed feeding area, during the process of the seed posture adjustment groove aligning the seeds close to it, the elastic blocking structures block the seeds entering the seed posture adjustment groove from the outside of the seed posture adjustment groove and guide the seeds to move toward the seed picking hole which is in an open state and is directly opposite the seed posture adjustment groove.

[0024] In this embodiment, the seed picking and sowing quantity adjustment method incorporates an elastic blocking structure. Seeds partially entering the seed posture adjustment groove are compressed by other seeds, causing the elastic blocking structure to deform elastically. This allows the seeds partially entering the seed posture adjustment groove to easily fall completely into the groove, further improving the smoothness of seed entry. Additionally, the elastic blocking structure can also block and guide the movement of seeds entering the seed posture adjustment groove, further improving the smoothness of seed entry into the open seed picking hole, thus helping to avoid seed shortages in the open seed picking hole.

[0025] According to one embodiment of the present invention, controlling the on / off state of several seed-taking holes among the multiple seed-taking holes on each seed-taking structure to achieve seed entry restriction specifically involves: using a detachable seed-taking hole blocking structure to block several of the multiple seed-taking holes, so that no seeds enter the blocked seed-taking holes.

[0026] In this embodiment, the seed collection and sowing quantity adjustment method uses a seed collection hole blocking structure to block several seed collection holes among multiple seed collection holes, preventing seeds from entering the blocked seed collection holes. This restricts the progress of seed collection holes that require seed entry limitation, and the method of limiting the progress of seed collection holes is simple. Furthermore, the seed collection hole blocking structure is detachable. According to the seed entry requirement of the land to be sown, a suitable seed collection hole blocking structure can be replaced to block a certain number of seed collection holes to achieve seed entry limitation. This restricts the entry of a certain number of seed collection holes, ensuring that each seed collection structure has a suitable number of seed collection holes for seed collection, storage, and sowing. This achieves the adjustment of the seeding quantity of the seeder, and the seeding quantity can be adjusted simply by changing the suitable seed collection hole blocking structure. The method of adjusting the seeding quantity is simple, easy to implement, and helps to reduce implementation costs.

[0027] According to one embodiment of the present invention, the method of shielding several of the multiple seed collection holes using a detachable seed collection hole shielding structure specifically involves:

[0028] On the seed-collecting structure, a mounting groove is provided on one side of the seed-collecting hole along the axial direction of the roller assembly. The mounting groove is connected to the seed-collecting hole and extends to the outer periphery of the seed-collecting hole.

[0029] The seed-collecting hole shielding structure has a number of seed passage openings for passing seeds to pass through a number of seed-collecting holes among a plurality of seed-collecting holes. The seed-collecting hole shielding structure with a suitable number of seed passage openings is selected according to the number of seed-collecting holes to be shielded as needed.

[0030] The selected seed-collecting hole blocking structure is detachably inserted into the mounting slot, so that several seed passages are directly opposite several seed-collecting holes, and the seed-collecting hole blocking structure blocks the seed-collecting holes on the seed-collecting structure that are not directly opposite the seed passages.

[0031] In this embodiment, the seed picking and sowing quantity adjustment method has an installation groove on the seed picking structure, which facilitates the detachable installation of the seed picking hole shielding structure in the installation groove, thereby improving the reliability of the seed picking hole shielding structure installation. Furthermore, the seed picking hole shielding structure has several seed passages, which facilitates the restriction of seed entry into seed picking holes that do not have a seed passage directly facing them. This ensures that each seed picking structure has a suitable number of seed picking holes for seed picking, storage, and sowing, and also simplifies the structure of the seed picking hole shielding structure, which helps to reduce the production and use costs of the seeder.

[0032] According to an embodiment of the present invention, the seed picking and sowing quantity adjustment method further includes: providing a plurality of insertion ports on the side of the roller assembly in the axial direction corresponding to a plurality of the mounting grooves, and detachably inserting the seed picking hole shielding structure from the insertion ports and installing it in the mounting groove.

[0033] In this embodiment, the seed feeding quantity adjustment method has multiple insertion ports on the side of the roller assembly in the axial direction. When it is necessary to adjust the seed feeding quantity of the seeder, the on / off state of the seed feeding hole is controlled by changing the appropriate seed feeding hole shielding structure to achieve seed feeding restriction. This allows for quick adjustment of the seed feeding quantity of the seeder, which is beneficial for quickly adjusting the seed feeding quantity and meeting the seed feeding quantity requirements of different lands to be sown.

[0034] According to one embodiment of the present invention, controlling the opening and closing state of several seed-taking holes among the multiple seed-taking holes on each seed-taking structure to achieve seed entry restriction specifically involves: blocking several of the multiple seed-taking holes with a detachable blocking block, so that no seeds enter the blocked seed-taking holes.

[0035] In this embodiment, the seed collection and sowing quantity adjustment method uses blocking blocks to block several seed collection holes in multiple seed collection holes, so that no seeds enter the blocked seed collection holes. This method is easy to implement and highly flexible. Furthermore, the blocking blocks are detachable, so that the sowing quantity can be adjusted by using an appropriate number of blocking blocks. The method of adjusting the sowing quantity is simple, easy to implement, and helps to reduce implementation costs.

[0036] In addition, the present invention provides a seeder in which the seeding quantity is adjusted by the above-mentioned seed picking and feeding quantity adjustment method during the seeding process. The seeder includes: a traction device for driving the seeder to move; a frame connected to the traction device; multiple seeders arranged in an array on the frame; and a seed storage box installed on the frame, which is connected to the seed storage cavity through a seed conveying pipe.

[0037] In this embodiment, the seeder uses the above-mentioned seed feeding and feeding quantity adjustment method to adjust the seed feeding quantity, which is beneficial to adjust the seed feeding quantity of the seeder according to the seed feeding quantity requirements of the land to be sown, thereby improving the applicability of the seeder to different lands to be sown; furthermore, multiple seeders are arrayed on the frame, which is beneficial to the seeder to achieve uniform sowing.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0051] This embodiment provides a method for adjusting the quantity of seeds collected and sown, including:

[0052] Adopting such Figures 1 to 7 The seeder shown is used to pick up and plant seeds. The seeder includes a roller assembly 1, and the roller assembly 1 has a seed storage cavity for storing seeds.

[0053] Multiple seed-picking structures 2 are provided circumferentially along the inner side of the roller assembly 1 for picking up, storing and dispensing seeds stored in the seed storage cavity. Multiple seed-picking holes 24 are provided circumferentially along the axial direction of the roller assembly 1 for picking up seeds. Each seed-picking hole 24 can hold one seed. During the rolling process of the roller assembly 1, a seed-picking area, a seed-storing area, and a seed-dispensing area are formed within the roller assembly 1.

[0054] Based on the seed quantity requirements of the land to be sown, the on / off state of several seed-collecting holes 24 on each seed-collecting structure 2 is controlled to restrict seed intake, ensuring that each seed-collecting structure 2 has a suitable number of seed-collecting holes 24 for seed collection, storage, and dispensing. The amount of seeds that each seed-collecting structure 2 can collect and dispense in each seed-collecting and dispensing cycle is adjusted. An appropriate amount of seeds are stored in the seed storage cavity, and the roller assembly 1 is driven to rotate. During the rotation of the roller assembly 1, the seed-collecting structure 2 collects and dispenses a certain number of seeds in each seed-collecting and dispensing cycle.

[0055] In this embodiment, as Figures 1 to 7 As shown, the seed picking and sowing quantity adjustment method in this embodiment uses a seed picker where each seed picking hole 24 can hold one seed. This helps ensure that each seed picking hole 24 holds only one seed in the sowing area, and thus ensures that only one seed is discharged from each seed picking hole 24 in the sowing area. Furthermore, the number of seed picking holes 24 on each seed picking structure 2 is determined, and the opening and closing states of several seed picking holes 24 on each seed picking structure 2 are controlled to limit the sowing process. Each seed-collecting structure 2 has a suitable number of seed-collecting pits 24 for seed collection, storage, and dispensing, thereby adjusting the number of seeds collected by each seed-collecting structure 2 in a seed-collecting cycle. This allows for the adjustment of the number of seeds dispensed by the seeder in each dispensing cycle. Each seed-collecting structure 2 collects a fixed number of seeds in a seed-collecting cycle and dispenses a fixed number of seeds in a dispensing cycle, thus achieving precise seed collection and dispensing. This allows for the adjustment of the seed dispensing amount to meet the different seed dispensing requirements of different lands to be sown, and the method of adjusting the seed dispensing amount is simple and easy to implement.

[0056] In one embodiment of the present invention, the on / off state of several seed-taking holes 24 among the multiple seed-taking holes 24 on each seed-taking structure 2 is controlled to achieve seed intake restriction, so that each seed-taking structure 2 has an equal number of seed-taking holes 24 for seed taking, storing and feeding.

[0057] In this embodiment, after imposing a seed intake restriction on the seed intake holes 24 on each seed intake structure 2 in the seed intake quantity adjustment method, each seed intake structure 2 has an equal number of seed intake holes 24 for seed intake, storage and intake. This is beneficial for each seed intake structure 2 to take out an equal number of seeds in one seed intake cycle and put out an equal number of seeds in one intake cycle, thereby achieving precise seed intake and intake, and facilitating uniform sowing.

[0058] One embodiment of the present invention, such as Figure 4 As shown, the methods for adjusting the quantity of seeds taken and sown also include:

[0059] Multiple seed outlets 171 are provided at intervals around the wheel surface of the roller assembly 1. The multiple seed outlets 171 are respectively connected to the seed storage cavity. Multiple seed taking structures 2 are installed on the inner wheel surface of the roller assembly 1 at intervals around the seed outlets 171, corresponding to the seed outlets 171. They are located in the seed storage cavity.

[0060] Multiple seed-into-soil mechanisms are provided on the outer wheel surface of the roller assembly 1, corresponding to multiple seed discharge outlets 171. These mechanisms are used to insert seeds discharged from the seed discharge outlets 171 into the soil. Each seed-into-soil mechanism has a seed transmission channel that communicates with the seed discharge outlets 171. During the rolling of the roller assembly 1, in the seed-into-soil area, the seeds stored in the seed-taking hole 24 on the seed-taking structure 2 located in the seed-into-soil area are discharged from the seed discharge outlets 171 and enter the soil through the seed transmission channel.

[0061] In this embodiment, as Figures 1 to 3 As shown, the seed-taking and seed-planting quantity adjustment method has multiple seed-planting mechanisms connected to the outer wheel surface of the roller assembly 1, which facilitates the seed-planting into the soil through the seed-planting mechanism. This ensures that the position and depth of the seed-planting into the soil are suitable, and also improves the uniformity of seed distribution after being planted into the soil, which is conducive to reasonable dense planting and increasing yield.

[0062] In this embodiment, as Figures 1 to 3As shown, the seed-into-soil mechanism in this embodiment is a seeding nozzle 9, and multiple seeding nozzles 9 are installed on the outer wheel surface of the roller assembly 1, corresponding one-to-one with multiple seed discharge outlets 171. Furthermore, the seeding nozzle 9 in this embodiment includes a fixing part 92, a nozzle closing baffle 91, a rotating rocker 90, and a return spring 93. The fixing part 92 is provided with a seeding channel, and the fixing part 92 is fixedly connected to the outer wheel surface of the roller assembly 1, and the seeding channel is connected to the seed discharge outlet 171.

[0063] Furthermore, such as Figures 1 to 3 As shown, the lower end of the nozzle closing baffle 91 is rotatably connected to the fixed part 92. One end of the rotating rocker 90 is fixedly connected to the lower end of the nozzle closing baffle 91. The nozzle closing baffle 91 can rotate relative to the fixed part 92 under the drive of the rotating rocker 90 to open and close the seeding channel. The other end of the rotating rocker 90 extends away from the nozzle closing baffle 91 to form an arc-shaped free end. The middle of the free end of the rotating rocker 90 is provided with a clearance for avoiding the fixed part 92 that is close to it during rotation. One end of the return spring 93 is connected to the free end of the rotating rocker 90, and the other end of the return spring 93... The end is connected to the wheel surface of the roller assembly 1, and each rotating rocker 90 is supported by two return springs 93. The two return springs 93 are located on both sides of the clearance opening. When the free end of the rotating rocker 90 is subjected to pressure on the wheel surface of the roller assembly 1, the return spring 93 is compressed, and the rotating rocker 90 drives the hole closing baffle 91 to rotate away from the fixed part 92 and open the sowing channel. When the free end of the rotating rocker 90 is relieved of the pressure on the wheel surface of the roller assembly 1, the return spring 93 returns to its elasticity, and the rotating rocker 90 drives the hole closing baffle 91 to rotate close to the fixed part 92 and close the sowing channel.

[0064] Furthermore, such as Figures 1 to 4 As shown, in this embodiment, the portion of the rotating rocker 90 near the apex closing baffle 91 is rotatably mounted on the wheel body of the roller assembly 1 via a rotating support rod. The rotating support rod passes horizontally through the rotating rocker 90 along the axial direction of the wheel body of the roller assembly 1, and both ends of the rotating support rod are fixedly connected to the wheel body of the roller assembly 1. In this embodiment, the roller assembly 1 is provided with a blocking annular disk 13 and a rolling disk 14, and both ends of the rotating support rod are specifically fixed to the inner sidewalls of the edges of the blocking annular disk 13 and the rolling disk 14, respectively.

[0065] Furthermore, such as Figures 1 to 3As shown, during the rolling of the roller assembly 1, in the seed-feeding area, the seeds stored in the seed-collecting hole 24 fall into the seeding channel of the seeding nozzle 9 under the action of gravity, and then the seeding channel of the seeding nozzle 9 is opened for sowing. It should be noted that in this embodiment, the seeding nozzle 9 is in a state where the rotating seesaw 90 is not under pressure, the return spring 93 is not compressed, and the seeding channel of the seeding nozzle 9 is in a closed state. During the sowing process, the seeding channel of the seeding nozzle 9 is opened due to the pressure of the rotating seesaw 90 against the soil. Alternatively, the seed-feeding mechanism in this embodiment can also adopt other seed-feeding structures in the prior art to achieve the goal of simply feeding the seeds into the soil.

[0066] One embodiment of the present invention, such as Figures 2 to 5 As shown, the methods for adjusting the quantity of seeds taken and sown also include:

[0067] The roller assembly 1 has a seed-taking structure 2 with a corresponding seed posture adjustment structure 2 and multiple seed posture adjustment structures 3. The multiple seed posture adjustment structures 3 are installed in the seed storage cavity with circumferential rotation close to the seed-taking structure 2 along the axial direction of the roller assembly 1. The seed posture adjustment structure 3 has multiple seed posture adjustment slots 311 for adjusting the posture of the seeds, which are located on the side facing the seed-taking structure 2 and corresponding to multiple seed-taking holes 24. The seed posture adjustment slots 311 are open on the side facing the seed-taking structure 2 and the outline of the seed posture adjustment slots 311 is adapted to the shape of the seeds. The seed posture adjustment slots 311 can adjust the posture of the seeds close to them and sequentially accommodate and face the open seed-taking hole 24 through a seed whose posture is adapted to the seed posture adjustment slot 311.

[0068] By providing a swing drive mechanism on the roller assembly 1, the seed posture adjustment structure 3 is connected to the swing drive mechanism, so that the seed posture adjustment structure 3 can swing relative to the seed picking structure 2 under the drive of the swing drive mechanism. During the rolling of the roller assembly 1, in the seed feeding area, the posture of the seeds close to it is adjusted by the seed posture adjustment groove 311. Seeds whose posture matches the seed posture adjustment groove 311 enter the seed posture adjustment groove 311 of the seed posture adjustment structure 3 located in the seed feeding area. In the seed storage area, the seeds that have entered the seed posture adjustment groove 311 enter and are stored in the seed picking hole 24 of the seed picking structure 2 located in the seed storage area, which is in an open state. In the seed delivery area, the seeds stored in the seed picking hole 24 are delivered from the seed picking hole 24 of the seed picking structure 2 located in the seed delivery area and discharged through the seed discharge outlet 171.

[0069] In this embodiment, as Figures 2 to 5As shown, in the seed picking and sowing quantity adjustment method, multiple seed posture adjustment slots 311 are provided on the seed posture adjustment structure 3, corresponding one-to-one with multiple seed picking holes 24, for adjusting the posture of the seeds. The seed posture adjustment structure 3 swings relative to the seed picking structure 2 under the drive of the swing drive mechanism, causing the seeds close to the seed posture adjustment slots 311 to adjust their posture under the action of the slots 311. This facilitates the adaptation of the posture of the seeds close to the seed posture adjustment slots 311 to the seed posture adjustment slots 311. Seeds whose posture is compatible with the seed posture adjustment groove 311 enter the seed posture adjustment groove 311 and then enter the seed picking hole 24, improving the smoothness of seed entry into the seed picking hole 24 and avoiding seed shortage when the seed picking hole 24 is open. Furthermore, the seed posture adjustment groove 311 can only accommodate and pass through one seed whose posture is compatible with the seed posture adjustment groove 311, avoiding multiple seeds being squeezed into the seed posture adjustment groove 311 at the same time and causing seed blockage, further improving the accuracy of seed picking and sowing by the seeder.

[0070] In this embodiment, as Figures 2 to 5 As shown, the swing drive mechanism is mounted on the roller assembly 1, and the seed posture adjustment structure 3 is connected to the swing drive mechanism and can swing relative to the seed picking structure 2 under the drive of the swing drive mechanism.

[0071] In this embodiment, as Figures 1 to 5 As shown, the roller assembly 1 includes: a support shaft 10, which is horizontally arranged; a fixed disc 11, which is fixedly connected to the support shaft 10 perpendicularly; a rolling disc 14, which is rotatably mounted on the support shaft 10 parallel to the fixed disc 11; and an annular wheel body, which is fixedly connected to the rolling disc 14 near its edge. The annular wheel body is located between the fixed disc 11 and the rolling disc 14. The fixed disc 11 is movably stopped against one side of the annular wheel body. The inner surface of the annular wheel body is provided with an annular groove. The surface of the annular wheel body is provided with multiple seed outlets 171 at equal intervals. The seed outlets 171 communicate with the annular groove, and the multiple seed outlets 171 discharge seeds into the annular groove. The seed-taking structure 2 is installed in the annular groove. The seed posture adjustment structure 3 includes a rotating connection part and a seed posture adjustment part 31. The rotating connection part is rotatably installed on the annular wheel body at both ends along the axial direction of the roller assembly 1. The seed posture adjustment part 31 is located in the annular groove, and one end of the seed posture adjustment part 31 is connected to the rotating connection part. The other end of the seed posture adjustment part 31 extends away from the rotating connection part to form a free end. A plurality of seed posture adjustment grooves 311 are spaced apart on the free end of the seed posture adjustment part 31. The rotating connection part is connected to the swing drive mechanism and can swing relative to the seed-taking structure 2 under the drive of the swing drive mechanism.

[0072] In the seed feeding area, the seed posture adjustment structure 3, driven by the swing drive mechanism, swings near the wheel surface of the roller assembly 1 to open the seed picking hole 24. When the seed feeding channel formed between the seed picking hole 24 and the seed posture adjustment groove 311 is fully opened, the seeds in the seed posture adjustment groove 311 can enter the seed picking hole 24 from the seed posture adjustment groove 311.

[0073] In the seed storage area, the seed posture adjustment structure 3, driven by the swing drive mechanism, swings away from the wheel surface of the roller assembly 1 to open the seed picking hole 24. The seed picking structure 2, which stores the seeds, rolls toward the top of the roller assembly 1. The seeds in the seed picking hole 24 remain in the seed picking hole 24 during the rolling process. Alternatively, at least a part of the seed posture adjustment structure 3 blocks the seed picking hole 24, and the seed posture adjustment structure 3 can block and restrict the seeds in the seed picking hole 24.

[0074] In the seeding area, the seed posture adjustment structure 3, driven by the swing drive mechanism, swings away from the wheel surface of the roller assembly 1 to open the seed picking hole 24. When the seed picking hole 24 and the seed discharge outlet 171 are fully opened, the seeds in the seed picking hole 24 can be thrown out from the seed picking hole 24 and discharged from the seed discharge outlet 171.

[0075] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, an annular groove is provided on the annular wheel body of the roller assembly 1, which facilitates the installation of the seed picking structure 2 and the seed posture adjustment structure 3 in the annular groove; in addition, a support shaft 10 is provided on the roller assembly 1, which facilitates the fixing of the roller assembly 1 to the frame of the seeder by fixing the support shaft 10 to the frame of the seeder, and facilitates the quick installation of the seeder on the frame of the seeder.

[0076] In this embodiment, as Figures 1 to 3As shown, in this embodiment, a connecting protrusion 141 is provided in the middle of the inner side of the rolling disk 14. A shaft hole for the support shaft 10 is provided in the middle of the connecting protrusion 141. A support sleeve 142 is provided on the connecting protrusion 141. The support sleeve 142 extends forward perpendicularly to the rolling disk 14 to form a free end, and a stepped mounting section is provided on the outer wall of the free end of the support sleeve 142. The support sleeve 142 is rotatably mounted on the outer periphery of the support shaft 10 by at least two bearings and is fixedly limited by a limiting bushing 103. Further, the fixed disk 11... A support protrusion ring 113 is provided in the middle of the outer side of the support shaft 10, and a shaft hole 2 for the support shaft 10 to pass through is formed in the middle of the support protrusion ring 113. In addition, a support sleeve 2 is provided in the middle of the inner side of the fixed disk 11 corresponding to the support sleeve 142. The support sleeve 2 extends backward perpendicular to the fixed disk 11 to form a free end. The support sleeve 2 is also supported and fixedly installed on the outer periphery of the support shaft 10 by at least two bearings. The free end of the support sleeve 2 is rotated and sleeved on the outer side of the stepped mounting section on the support sleeve 142 by the bearings, so that the support sleeve 142 can rotate relative to the support sleeve 2.

[0077] Furthermore, such as Figures 1 to 4 As shown, in this embodiment, the front end of the support shaft 10 is fixed by a locking nut 101, and a washer 102 is installed between the locking nut 101 and the support ring 113; the middle of the rear end of the rolling disc 14 is provided with an installation groove, the support bearing 143 is fixed to the rear end of the support shaft 10 and installed in the installation groove, the rear end of the support bearing 143 is locked by a locking nut 145, and a washer 144 is installed between the locking nut 145 and the support bearing 143.

[0078] Furthermore, such as Figure 1 As shown, in this embodiment, the fixed disc 11 is also provided with a seed input port for inputting seeds into the seed storage cavity. The output end of the seed delivery pipe 12 for conveying seeds into the seed storage cavity is connected to the outer periphery of the seed input port. The end of the seed input port of the seed delivery pipe 12 is provided with two connecting ears 121, which are fixed to the fixed disc 11 by bolts. Furthermore, the fixed disc 11 is also provided with an observation port 111 for observing the seed condition in the seed storage cavity, which is covered by a transparent cover. The fixed disc 11 is also provided with a seed unloading port 112 for unloading the seeds stored in the seed storage cavity, which is covered by a detachable seed unloading cover.

[0079] Furthermore, such as Figure 2 and Figure 4As shown, the annular wheel in this embodiment is composed of a first supporting ring 16 and a second supporting ring 17. The first supporting ring 16 is located near the fixed disk 11 and has an annular convex rail protruding inward. The second supporting ring 17 is located near the rolling disk 14 and has an annular convex rail protruding inward. The second supporting ring 17 has an annular connecting protrusion on the side facing the first supporting ring 16. The annular connecting protrusion extends towards the first supporting ring 16 to form an extension end. The first supporting ring 16 is connected to the extension end of the annular connecting protrusion to form the annular wheel. The first and second annular convex rails are arranged parallel to each other, and an annular groove is defined between the first and second annular convex rails. Furthermore, in this embodiment, multiple seed outlets 171 are equidistantly spaced on the annular connecting protrusion of the second supporting ring 17.

[0080] Furthermore, such as Figure 2 , Figure 5 As shown, in this embodiment, the seed-taking structure 2 has an installation protrusion 20 on its outer side, and the inner sidewall of the annular connecting protrusion supporting the second ring 17 has an installation groove 2. The installation protrusion 20 is installed in the installation groove 2, and the seed-taking structure 2 is fixedly installed in the annular groove. Furthermore, the annular wheel in this embodiment can also be configured with other structures to facilitate the formation of the annular groove.

[0081] Furthermore, such as Figure 1 , Figure 4 As shown, the roller assembly 1 in this embodiment is also provided with a blocking annular disk 13. The blocking annular disk 13 is fixed to the rolling disk 14 by a plurality of fixing bolts 18. Specifically, the edge of the rolling disk 14 is provided with a support protrusion, and the support protrusion is provided with a plurality of connecting through holes I at intervals. The blocking annular disk 13 is provided with a plurality of connecting through holes II corresponding to the connecting through holes I. The front ends of the fixing bolts 18 pass through the connecting through holes I and the connecting through holes II respectively, and are locked with nuts to fix the blocking annular disk 13 and the rolling disk 14.

[0082] Furthermore, such as Figure 1 , Figure 4 As shown, in this embodiment, in order to ensure that the fixed disc 11 can be moved and abutted against one side of the blocking annular disc 13 to prevent seeds from leaking out of the seed storage cavity through the gap between the fixed disc 11 and the blocking annular disc 13, this embodiment provides a stepped circular groove in the middle of the blocking annular disc 13, and the fixed disc 11 is installed close to the blocking annular disc 13 and housed in the stepped circular groove.

[0083] In this embodiment, as Figures 2 to 5 , Figure 7 As shown, the rotating connection part is connected to one end of the support ring 16 and extends outward from the inside of the support ring 16. The swing drive mechanism includes:

[0084] The swing drive ring 15 is installed on one side of the fixed disc 11, and the swing drive ring 15 is provided with an outwardly protruding swing drive rail 151 on the side of the seeding area. The swing drive rail 151 includes multiple arc-shaped protrusions and multiple arc-shaped grooves arranged alternately.

[0085] The swing arm 6 includes a swing connecting arm 60 and a stop shaft 61. One end of the swing connecting arm 60 is connected to one end of the rotating connecting part that passes through the support ring 16. The stop shaft 61 is connected to one side of the swing connecting arm 60 and extends toward the swing drive ring 15 and stops the swing arm 60 tangentially to the outer side of the swing drive ring 15.

[0086] The torsion spring 8 includes a spiral body and torsion arms 1 and 2 connected to the two ends of the spiral body respectively. The spiral body is sleeved on the rotating connection part and located between the swing connection arm 60 and the seed posture adjustment part 31. Torsion arm 1 is abutted and connected to the support ring 16, and torsion arm 2 is abutted and connected to the swing connection arm 60. When the roller assembly 1 rolls, when the abutting shaft 61 is tangential to the outer circumferential side of the swing drive ring 15, the swing arm 6 drives the seed posture adjustment structure 3 to swing and completely close the seed inlet channel formed between the seed picking hole 24 and the seed posture adjustment groove 311. When the abutting shaft 61 passes the swing drive convex rail 151 and moves against multiple arc-shaped protrusions and multiple arc-shaped grooves in sequence under the action of the torsion spring 8, it drives the swing arm 6 to swing. The swing arm 6 can drive the seed posture adjustment structure 3 to swing intermittently and completely open the seed inlet channel formed between the seed picking hole 24 and the seed posture adjustment groove 311.

[0087] In this embodiment, as Figure 2 and Figure 4 As shown, the swing drive ring 15 is fixed to the inner side of the fixed disk 11. The swing drive ring 15 is provided with multiple connecting ears 152 spaced apart in the circumferential direction. The connecting ears 152 are specifically fixed to the fixed disk 11 by bolts. The swing drive ring 15 is provided with a swing drive convex rail 151 protruding outward on one side of the seed entry area. The swing drive convex rail 151 includes multiple arc-shaped protrusions and multiple arc-shaped grooves arranged alternately. The stop shaft 61 on the swing arm 6 is tangent to the circumferential outer side of the swing drive ring 15 and can pass through the swing drive convex rail 151 and move in sequence against multiple arc-shaped protrusions and multiple arc-shaped grooves under the action of the torsion spring 8, thereby driving the swing arm 6 to swing. The swing arm 6 can drive the seed posture adjustment structure 3 to swing intermittently and fully open the seed entry channel formed between the seed picking hole 24 and the seed posture adjustment groove 311, thereby facilitating the seed entry into the seed picking hole 24 in the seed storage cavity of the seed entry area.

[0088] Furthermore, such as Figure 2 , Figure 4 and Figure 7As shown, in this embodiment, the rotating connection part on the seed posture adjustment structure 3 is a rotating shaft 30, and the seed posture adjustment part 31 is fixedly connected to one side of the rotating shaft 30. The first annular convex rail is provided with a first mounting through hole, and the front end of the rotating shaft 30 is rotatably installed in the first mounting through hole and passes forward through the first annular convex rail; the second annular convex rail is provided with a second mounting through hole, and the rear end of the rotating shaft 30 is rotatably installed in the second mounting through hole; furthermore, in order to further improve the rotational stability of the rotating shaft 30, a first rotating support sleeve is installed in the first mounting through hole, and a second rotating support sleeve 32 is installed in the second mounting through hole, and the two ends of the rotating shaft 30 are respectively rotated and supported by the first rotating support sleeve and the second rotating support sleeve 32.

[0089] Furthermore, such as Figure 4 , Figure 7 As shown, the seed taking structure 2 in this embodiment is provided with a support block 21. The support block 21 is connected to the mounting protrusion 20 and extends to the inside of the roller assembly 1. An arc-shaped rotating clearance groove 22 is provided on one side of the support block 21. The rotating shaft 30 rotates in the mounting through hole one and the mounting through hole two. The middle part of the rotating shaft 30 is housed in the arc-shaped rotating clearance groove 22.

[0090] Furthermore, such as Figure 5 and Figure 7 As shown, in this embodiment, the rotating shaft 30 has a mounting head 301 at one end passing through the annular convex rail. The mounting head 301 has a rectangular structure. In this embodiment, the swing arm 6 has a insertion slot 601 at one end. The mounting head 301 is inserted into the insertion slot 601 to connect the swing arm 6 to the mounting head 301. The other end of the swing arm 6 extends parallel to the annular convex rail and is connected to a stop shaft 61. The stop shaft 61 extends toward the fixed disc 11. In this embodiment, the swing connecting arm 60 has a pin hole 602 at one end with the insertion slot 601. The mounting head 301 has a pin hole 3011 corresponding to the pin hole 602. A pin 7 is inserted into the pin hole 602 and the pin hole 3011. The pin 7 limits the swing arm 6 to the mounting head 301.

[0091] Furthermore, such as Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, a swing drive ring 15 is fixedly connected to one side of the fixed disc 11 corresponding to the stop shaft 61. The swing drive ring 15 is provided with a swing drive convex rail 151 protruding outward on one side of the seed-feeding area. The stop shaft 61 is tangent to the swing drive ring 15 around the outside. During the rolling process of the roller assembly 1, when the stop shaft 61 passes the arc-shaped protrusion on the swing drive convex rail 151, the swing arm 6 swings outward away from the swing drive ring 15, driving the seed posture adjustment part 31 to swing and fully open the seed-feeding channel formed between the seed-taking hole 24 and the seed posture adjustment groove 311. When the stop shaft 61 passes the arc-shaped groove on the swing drive convex rail 151, the swing arm 6 swings close to the swing drive ring 15 under the action of the torsion spring 8, driving the seed posture adjustment part 31 to swing and close part of the seed-feeding channel formed between the seed-taking hole 24 and the seed posture adjustment groove 311.

[0092] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, multiple arc-shaped protrusions and arc-shaped grooves are connected by a circular arc transition. When the stop shaft 61 passes the highest point of the arc-shaped protrusion, the swing arm 6 drives the seed posture adjustment part 31 to swing and fully open the seed inlet channel formed between the seed collection hole 24 and the seed posture adjustment groove 311. This facilitates the rotation of the rotating shaft 30 to open the seed inlet channel formed between the seed collection hole 24 and the seed posture adjustment groove 311 multiple times, ensuring that at least one seed can enter and be stored in the seed collection hole 24. Furthermore, in order to better block and restrict the seeds in the seed collection hole 24 in the seed storage area, at least a part of the seed posture adjustment structure 3 can also block the seed collection hole 24. The seed posture adjustment structure 3 can block and restrict the seeds located in the seed collection hole 24. The arc-shaped protrusion can be extended to the seed storage area, so that when the stop shaft 61 and the arc-shaped protrusion in the seed storage area stop, at least a part of the seed posture adjustment structure 3 blocks the seed collection hole 24. Furthermore, the oscillating drive mechanism can also be used for other rotary drive devices.

[0093] In this embodiment, as Figure 7 As shown, the first torsion arm on the torsion spring 8 is specifically connected to the support ring 16. The front side of the annular convex rail of the support ring 16 is provided with a limiting groove for engaging the first torsion arm, and the first torsion arm is installed in the limiting groove. The second torsion arm on the torsion spring 8 is inserted into the swing connecting arm 60. The swing connecting arm 60 is provided with a limiting through hole 603, and the second torsion arm is inserted into the limiting through hole 603. It should be noted that the roller assembly 1 in this embodiment can also be configured with other structures, which is beneficial for the seeder to perform sowing.

[0094] In this embodiment, as Figure 7As shown, the end face of the free end of the seed posture adjustment part 31 protrudes towards the seed picking structure 2 to form an arc-shaped protrusion. The seed picking hole shielding structure 4 connected to the seed picking structure 2 and the end face of the seed picking structure 2 facing the arc-shaped protrusion together deviate from the arc-shaped protrusion to form a swing avoidance arc-shaped groove. When the seed posture adjustment part 31 swings, the arc-shaped protrusion can adapt to and abut against the swing avoidance arc-shaped groove to swing and swing through the swing avoidance arc-shaped groove.

[0095] In this embodiment, as Figure 4 and Figure 7 As shown, in this embodiment, the rotating connecting part is horizontally installed within the roller assembly 1 parallel to the rotation center of the roller assembly 1. The seed picking structure 2 is horizontally installed within the roller assembly 1 parallel to the rotating connecting part. The length direction of the seed posture adjustment groove 311 is the same as the extension direction of the seed posture adjustment part 31. The inner port of the seed posture adjustment groove 311 is a large U-shaped opening. The maximum width of the large U-shaped opening is greater than the width of any single seed and less than the total width of any two seeds. The maximum length of the large U-shaped opening is greater than the length of any single seed and less than the total length of any two seeds. The U-shaped opening extends towards the outer port of the seed posture adjustment groove 311, and the sealing end of the large U-shaped opening contracts towards the opening end of the large U-shaped opening as the extension depth of the U-shaped opening increases. After extending to a position near the outer port of the seed posture adjustment groove 311, the large U-shaped opening narrows inward towards the inside of the seed posture adjustment groove 311 to form a small U-shaped opening. The maximum width of the small U-shaped opening is less than the width of any single seed, and the maximum length of the small U-shaped opening is less than the length of any single seed; this facilitates the entry of seeds located in the seed posture adjustment groove 311 into the seed collection hole 24 under the squeezing action of other seeds. In this embodiment, the seed posture adjustment groove 311 is suitable for wheat seeds and other seeds with similar shapes to wheat seeds.

[0096] It should be noted that the “posture” of the seeds in this embodiment refers to the placement posture of the seeds. The seed posture matching the seed posture adjustment groove 311 means that the placement posture of the seeds matches the outline of the seed posture adjustment groove 311, and the seeds can enter the seed posture adjustment groove 311.

[0097] In this embodiment, as Figure 5 and Figure 7As shown, the maximum width of the seed posture adjustment groove 311 is greater than the width of any single seed and less than the total width of any two seeds; the maximum length of the seed posture adjustment groove 311 is greater than the length of any single seed and less than the total length of any two seeds; the seed picking hole 24 is recessed inward along the length direction of the aligning groove towards the seed picking component; the depth of the recess in the seed picking hole 24 is not less than the length of any single seed and less than the total length of any two seeds; the length of the seed is less than twice the width of the seed; this ensures that only one seed is stored in the seed picking hole 24, ensuring the accuracy of the seeder in picking seeds whose length is less than twice the width of the seed. It should be noted that the outline and size of the seed posture adjustment groove 311 are designed according to the shape of different types of seeds. In addition, the "any one seed" and "any two seeds" mentioned above refer to seeds in the ideal seed pool or seeds after removing inferior seeds. Furthermore, the "inner and outer sides" of the seed posture adjustment groove 311 refer to the position of the seed posture adjustment groove 311 installed in the roller assembly 1 with the seed posture adjustment structure 3 relative to the seed storage cavity in the roller assembly 1.

[0098] One embodiment of the present invention, such as Figure 5 and Figure 7 As shown, the seed picking and feeding quantity adjustment method further includes: providing multiple elastic blocking structures corresponding to the seed posture adjustment structure 3 in the roller assembly 1, one end of the elastic blocking structure is connected to the outside of the seed posture adjustment structure 3, and the other end of the elastic blocking structure extends to the outer port of the seed posture adjustment groove 311 and blocks the outside of the seed posture adjustment groove 311; during the rolling of the roller assembly 1, in the seed feeding area, during the process of the seed posture adjustment groove 311 aligning the seeds close to it, the elastic blocking structures block the seeds entering the seed posture adjustment groove 311 from the outside of the seed posture adjustment groove 311 and guide the seeds to move towards the seed picking hole 24 which is in an open state and is set directly opposite to the seed posture adjustment groove 311.

[0099] In this embodiment, as Figure 5 and Figure 7As shown, the seed picking and sowing quantity adjustment method incorporates an elastic blocking structure. Seeds partially entering the seed posture adjustment groove 311 are compressed by other seeds, causing the elastic blocking structure to deform elastically. This allows the seeds partially entering the seed posture adjustment groove 311 to easily fall completely into the groove, further improving the smoothness of seed entry. Additionally, the elastic blocking structure can also block seeds entering the seed posture adjustment groove 311 and guide them towards the open seed picking hole 24, which is directly opposite the groove. This further improves the smoothness of seed entry into the open seed picking hole 24, helping to avoid seed shortages and ultimately improving the accuracy of seed picking and sowing by the seeder.

[0100] In this embodiment, as Figure 5 , Figure 7 As shown, the elastic blocking component is a brush 5, and the bristles 51 on the brush 5 are independent of each other. When a portion of the seed is squeezed against a portion of the bristles 51, the squeezed bristles 51 undergo elastic deformation, thereby facilitating the seed to adapt to the contour adjustment posture of the seed posture adjustment groove 311 and fall into the seed posture adjustment groove 311. When the seed continues to squeeze the bristles 51, the seed comes into contact with more bristles 51, thereby blocking the seed. Furthermore, in this embodiment, the brush 5 includes a brush seat 50, and the bristles 51 are fixed on the brush seat 50. In order to facilitate the installation of the brush 5, a brush mounting groove 312 is provided on the outside of the seed posture adjustment structure 3, and the brush seat 50 is fixedly installed in the brush mounting groove 312. Furthermore, the elastic blocking structure can also use other elastic blocking components to facilitate the blocking of the seed.

[0101] One embodiment of the present invention, such as Figure 5 , Figure 7 As shown, controlling the on / off state of several seed-taking holes 24 among the multiple seed-taking holes 24 on each seed-taking structure 2 to achieve seed entry restriction is specifically achieved by: using a detachable seed-taking hole blocking structure 4 to block several of the multiple seed-taking holes 24, so that no seeds enter the blocked seed-taking holes 24.

[0102] In this embodiment, as Figure 5 , Figure 7As shown, the seed collection and sowing quantity adjustment method uses a seed collection hole blocking structure 4 to block several of the multiple seed collection holes 24, preventing seeds from entering the blocked seed collection holes 24. This restricts the progress of seed collection holes 24 that require seed entry restriction. The method of restricting the progress of seed collection holes 24 is simple and easy to implement. Furthermore, the seed collection hole blocking structure 4 is detachable. According to the seed entry requirements of the land to be sown, a suitable seed collection hole blocking structure 4 can be replaced to block a certain number of seed collection holes 24 to restrict seed entry. This restricts the entry of a certain number of seed collection holes 24, ensuring that each seed collection structure 2 has a suitable number of seed collection holes 24 for seed collection, storage, and sowing, thereby adjusting the seeding quantity of the seeder. The seeding quantity can be adjusted simply by replacing the suitable seed collection hole blocking structure 4. The method of adjusting the seeding quantity is simple, easy to implement, and helps to reduce implementation costs.

[0103] One embodiment of the present invention, such as Figure 7 As shown, the detachable seed collection hole shielding structure 4 is used to shield several of the multiple seed collection holes 24, specifically as follows:

[0104] On the seed-collecting structure 2, a mounting groove 23 is provided along the axial direction of the roller assembly 1 on one side where a seed-collecting hole 24 is provided. The mounting groove 23 is connected to the seed-collecting hole 24 and extends to the outer periphery of the seed-collecting hole 24.

[0105] The seed collection hole shielding structure 4 is provided with a number of seed passage openings 40 for passing seeds in a number of seed collection holes 24. The seed collection hole shielding structure 4 with a suitable number of seed passage openings 40 is selected according to the number of seed collection holes 24 to be shielded as needed.

[0106] The selected seed-collecting hole blocking structure 4 is detachably inserted into the installation groove 23, so that several seed passage openings 40 are directly opposite several seed-collecting holes 24, so that the seed-collecting hole blocking structure 4 blocks the seed-collecting holes 24 on the seed-collecting structure 2 that are not directly opposite the seed passage openings 40.

[0107] In this embodiment, as Figure 7As shown, in the seed collection and sowing quantity adjustment method, an installation groove 23 is provided on the seed collection structure 2, which facilitates the detachable installation of the seed collection hole shielding structure 4 within the installation groove 23, improving the reliability of the installation of the seed collection hole shielding structure 4. Furthermore, several seed passage openings 40 are provided on the seed collection hole shielding structure 4, which facilitates the restriction of seed entry into seed collection holes 24 that are not directly opposite a seed passage opening 40. This ensures that each seed collection structure 2 has a suitable number of seed collection holes 24 for seed collection, storage, and sowing, and also simplifies the seed collection process. The structure of the seed hole shielding structure 4 helps reduce the production and usage costs of the seeder. Furthermore, when adjusting the seed quantity, the seed hole shielding structure 4, equipped with a suitable number of seed passages 40, can restrict the seed entry into the seed collection holes 24 that require seed entry restriction, based on the seed quantity requirements of the land to be sown. This allows for simple and rapid adjustment of the seed quantity, quickly meeting the seed quantity requirements of different lands to be sown. Furthermore, the mounting groove 23 in this embodiment has an arc-shaped structure, but it can also be configured in other suitable shapes. Furthermore, the seed hole shielding structure 4 in this embodiment has four seed passages 40, while each seed collection structure 2 has five seed collection holes 24, with one seed collection hole 24 restricted from seed entry. Alternatively, the number of seed passages 40 can be three, two, or other configurations as needed.

[0108] In this embodiment, as Figure 7 As shown, the open end of the seed collection hole 24 is oval-shaped, and the seed passage 40 is also oval-shaped. After the seed collection hole blocking structure 4 is installed in the mounting groove 23 and several seed passages 40 are aligned with several seed collection holes 24, the seed passages 40 respectively form the inlet portion of the seed collection hole 24 that are aligned with them. This facilitates the smooth passage of seeds through the seed passages 40, especially when the seeds are wheat seeds. Furthermore, it helps to make the size of the groove formed by the seed passages 40 and the seed collection holes 24 that are aligned with them more closely approximate the size of a seed collection hole 24 with normal dimensions, reducing or avoiding the impact of the seed passages 40 on the accuracy of seed collection and storage in the seed collection holes 24.

[0109] One embodiment of the present invention, such as Figure 5 and Figure 6 As shown, the method for adjusting the number of seeds taken and fed also includes: multiple insertion ports are provided on the side of the roller assembly 1 in the axial direction corresponding to multiple mounting slots 23, and the seed-taking hole shielding structure 4 is detachably inserted into the insertion port and installed in the mounting slot 23.

[0110] In this embodiment, as Figure 5 and Figure 6As shown, the seed feeding quantity adjustment method involves multiple insertion ports on the axial side of the roller assembly 1, facilitating the insertion and installation of the seed feeding hole shielding structure 4 into the mounting groove 23. When the seed feeding quantity of the seeder needs to be adjusted, the original seed feeding hole shielding structure 4 is removed from the insertion port without disassembling the roller assembly 1. Then, based on the seed feeding quantity requirements of the land to be sown, a suitable seed feeding hole shielding structure 4 is replaced. After controlling the opening and closing state of the seed feeding hole 24 to restrict seed feeding, the seed feeding quantity of the seeder can be adjusted. This method facilitates rapid adjustment of the seed feeding quantity of the seeder, meeting the seed feeding quantity requirements of different lands to be sown. Furthermore, it eliminates the need to disassemble the roller assembly 1, minimizing the work required for adjusting the seed feeding quantity of the seeder, making operation convenient, and enabling further rapid adjustment of the seed feeding quantity to meet the seed feeding quantity requirements of different lands to be sown.

[0111] In this embodiment, as Figure 5 and Figure 6 As shown, the seed-taking hole shielding structure 4 has an arc-shaped plate structure. In this embodiment, the insertion port is a threaded through hole. The seed-taking hole shielding structure 4 is locked by a locking mechanism. The locking mechanism includes multiple locking parts 146, which are respectively provided for multiple insertion ports. The locking end of the locking part 146 is provided with a stop protrusion. The outer periphery of the stop protrusion is provided with an external thread that can be threadedly connected to the threaded through hole. The stop protrusion is provided with a stop groove for stopping the seed-taking hole shielding structure 4. The stop protrusion is threadedly connected to the threaded through hole. By tightening the locking part 146, the seed-taking hole shielding structure 4 extends into the stop groove and stops on the inner side wall of the stop groove, thereby locking the seed-taking hole shielding structure 4. Furthermore, in this embodiment, the insertion port is located on the rolling disc 14; furthermore, in this embodiment, the seed-taking hole blocking structure 4 can also be configured as other structures to facilitate the restriction of seed entry into the seed-taking hole 24; in addition, the locking mechanism can also adopt other locking mechanisms or locking components to facilitate the fixing and limiting of the seed-taking hole blocking structure 4.

[0112] In one embodiment of the present invention, controlling the opening and closing state of several seed-taking holes 24 among the multiple seed-taking holes 24 on each seed-taking structure 2 to achieve seed entry restriction specifically involves: blocking several seed-taking holes 24 among the multiple seed-taking holes 24 with a detachable blocking block, so that no seeds enter the blocked seed-taking holes 24.

[0113] In this embodiment, the seed collection and sowing quantity adjustment method uses blocking blocks to block several seed collection holes 24, thereby restricting the progress of seed collection holes 24 that require seed input restriction. This method is simple, easy to implement, and highly flexible. Furthermore, the blocking blocks are detachable, allowing for the use of an appropriate number of blocking blocks to block a certain number of seed collection holes 24 based on the seed input requirements of the land to be sown. This restricts the input of a defined number of seed collection holes 24, ensuring that each seed collection structure 2 has a suitable number of seed collection holes 24 for seed collection, storage, and sowing, thus adjusting the seed input of the seeder. The seed input can be adjusted using a suitable number of blocking blocks, making the adjustment method simple, easy to implement, and reducing implementation costs. Additionally, this embodiment does not illustrate the structure using blocking blocks to block the seed collection holes 24.

[0114] It should be noted that the seeder implementing the seed picking and sowing quantity adjustment method of this embodiment can also be configured with other structures, or existing seeders can be improved to make them suitable for implementing the seed picking and sowing quantity adjustment method of this embodiment.

[0115] In addition, this embodiment provides a seeder in which the seed quantity is adjusted by the above-mentioned seed picking and feeding method during the seeding process. The seeder includes: a traction device for driving the seeder to move; a frame connected to the traction device; multiple seeders, with an array of multiple seeders installed on the frame; and a seed storage box installed on the frame, which is connected to the seed storage cavity through a seed delivery pipe 12.

[0116] In this embodiment, the seeder uses the aforementioned seed dispensing and sowing quantity adjustment method to adjust the seed dispensing quantity. This is beneficial for adjusting the seed dispensing quantity according to the seed requirements of the land to be sown. By adjusting the number of seeds dispensed by the seeder in each sowing cycle, the seed dispensing quantity of the seeder can be adjusted to meet the seed dispensing quantity requirements of different lands to be sown, thus improving the applicability of the seeder to different lands. Furthermore, multiple seeders are arrayed on the frame, which facilitates precise seed dispensing and sowing by multiple seeders simultaneously. The accurate adjustment of the number of seeds dispensed by the seeders in each sowing cycle is beneficial for achieving uniform sowing. Furthermore, a seed storage box is installed on the frame, which facilitates the input of seeds stored in the seed storage box into the seed storage cavity. It should be noted that the structural diagram of the seeder array installed on the frame is not illustrated in this embodiment, and the method of installing the seeders on the frame can refer to existing sowing equipment, and will not be described in detail here.
