Description

Technical Field

[0001] This invention belongs to the field of electric seeder technology, and more specifically it relates to a multi-row electric seeder. Background Technology

[0002] As an indispensable core mechanical equipment in modern agriculture, the electric seeder's core mission is to efficiently, accurately, and evenly sow seeds to the appropriate depth in the soil, laying a solid foundation for high and stable crop yields.

[0003] Current mainstream designs typically use bolts to rigidly fix the seeder to the frame of the mobile chassis. However, this fixing method has significant drawbacks in practical applications:

[0004] 1. Difficult maintenance and disassembly: Seeders operate in moist soil environments for extended periods, inevitably causing the fixing bolts to become covered and soaked with mud. This easily leads to bolt corrosion and adhesion, making the disassembly process extremely laborious and time-consuming when the seeder needs repair or replacement, severely impacting equipment maintenance efficiency and operational continuity.

[0005] 2. Uneven sowing depth leads to waste: Farmland surfaces are generally uneven. Because the seeder is rigidly connected to the chassis and lacks independent terrain adaptability, it is difficult to maintain a constant sowing depth during movement. This severely uneven sowing depth not only directly wastes valuable seeds but also leads to uneven germination, large differences in seedling growth, and ultimately affects the overall yield potential.

[0006] In summary, existing electric seeders have significant shortcomings in terms of seeder fixing methods and terrain adaptability. In order to solve the problems of bolt corrosion and disassembly difficulties, improve adaptability to uneven surfaces and ensure consistent sowing depth, reduce seed waste and improve sowing quality, it is particularly urgent to carry out targeted optimization and improvement of the existing structure. Summary of the Invention

[0007] To address the problems of disassembly difficulties and inability to adapt to uneven ground in existing technologies, the present invention aims to provide a multi-row electric seeder that has the advantages of convenient and quick disassembly and installation of the seeder, rapid adjustment of row spacing, and adaptability to uneven ground.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A multi-row electric seeder includes a walking chassis, a seeder, and a frame. The frame is fixedly mounted on the walking chassis. At least one mounting rod is provided on the frame. The seeder is detached and mounted on the frame via a quick-release fixing mechanism and a seeder mounting seat. The mounting rod is provided with an adjustment mechanism for driving the quick-release fixing mechanism to move along the length of the mounting rod to adjust the seeding row spacing.

[0010] The advantages of this solution are at least as follows: Traditional seeders are cumbersome to install and replace, requiring multiple tools and a lot of time. However, in this embodiment, the quick-release fixing mechanism and the seeder mounting base make the installation and disassembly of the seeder simple and quick, without the need for complicated tools and long-term operation, which greatly saves the time of replacing the seeder. This allows for quick switching when facing different sowing tasks and effectively improves the overall efficiency of sowing operations.

[0011] Furthermore, existing seeders suffer from numerous inconveniences in row spacing adjustment. They either lack flexible row spacing adjustment capabilities or require complex mechanical structures and cumbersome operation. However, this embodiment achieves flexible row spacing adjustment through an adjustment mechanism, enabling the seeder to adapt to the planting requirements of different crops and various planting patterns, such as single-row, double-row, and wide-narrow-row planting. Growers can quickly set appropriate row spacing based on their actual planting plan and farmland layout, avoiding the need for repeated adjustments to the seeder's position or re-preparation due to mismatched row spacing. This further ensures efficient sowing operations and improves agricultural production efficiency.

[0012] In existing seeders, adjusting the seeding row spacing or replacing the seeder often requires multiple people to work together and repeatedly disassemble and reassemble parts, resulting in high labor intensity. The seeder in this solution can be quickly and easily completed by the operator, from the installation and disassembly of the seeder to the adjustment of the seeding row spacing, without the need for professional training or complicated operating skills.

[0013] The present invention is further configured such that: the quick-release fixing mechanism includes: a sliding seat and a main fixing component and a secondary fixing component disposed on the sliding seat; the sliding seat is slidably mounted on the mounting rod through an adjustment mechanism; the main fixing component is used to form a main snap-fit ​​fixing with the seeder mounting seat; and the secondary fixing component is used to form an auxiliary locking fixing with the seeder mounting seat.

[0014] The advantages of this scheme are at least as follows: the main fixing component first forms a primary snap-fit ​​fixation with the seeder mounting base, providing stable support and initial fixation for the seeder; the secondary fixing component further forms an auxiliary locking fixation with the seeder mounting base, enabling the seeder to achieve an extremely firm fixation effect after installation. Even when encountering various complex working conditions such as bumps and vibrations during the seeder's operation, the seeder is not easy to loosen or shift, thereby ensuring the accuracy of the sowing operation and avoiding problems such as uneven seeding and inconsistent sowing depth caused by the loosening of the seeder, thus improving the sowing quality.

[0015] Furthermore, since the quick-release fixing mechanism is installed on a sliding seat and slides along the mounting rod with the help of the adjustment mechanism, the row spacing adjustment of the seeder becomes more precise, flexible and convenient.

[0016] The present invention is further configured such that: the main fixing component includes a driving component and at least two pairs of oppositely arranged claws, and each pair of claws is hinged to a sliding seat via a rotating seat; the driving component is installed inside the sliding seat, and the output end of the driving component is hinged to one end of the claw.

[0017] The main fixing component also includes a snap-fit ​​groove formed on the seeder mounting base for the claw to snap into;

[0018] The inner side of the claw of the main fixing component is provided with anti-slip texture, and a torsion spring is installed between the hinge end of the claw and the sliding seat.

[0019] The advantages of this scheme are at least as follows: When the main fixing component is needed, the sliding seat is first slid to the pre-set installation position on the mounting rod via the adjustment mechanism. The adjustment mechanism can pre-adjust the position of the sliding seat according to actual needs so that the seeder can be installed in a suitable working position. Then, the seeder mounting base is aligned with the claw position of the main fixing component, and the locking groove on the seeder mounting base is aligned with the claw. The drive component is activated, and the output end of the drive component pushes one end of the claw, causing it to rotate around the hinge point of the rotating seat. The other end of the claw gradually engages in the locking groove until the anti-slip texture on the inner side of the claw is tightly fitted with the locking groove, completing the initial fixing of the seeder. The main fixing component, by using at least two pairs of opposing claws with anti-slip texture on the inner side, can provide strong clamping force and anti-slip effect when engaged with the locking groove of the seeder mounting base, ensuring that the seeder will not loosen even when subjected to various external forces during operation. Even if one of the drive components fails, the reaction force of the torsion spring can ensure that the claw remains locked.

[0020] The present invention is further configured such that: the secondary fixing component includes a drive motor, a bidirectional screw, a transmission mechanism, two clamping plates and several guide rods; the drive motor is installed inside the sliding seat; the bidirectional screw is rotatably installed inside the sliding seat and has two threaded sections with opposite directions of rotation; the transmission mechanism is installed between the output end of the drive motor and the bidirectional screw; the two clamping plates are respectively threadedly engaged with the two threaded sections of the bidirectional screw and slidably connected to the guide rods.

[0021] The secondary fixing component also includes a snap-fit ​​hole formed on the seeder mounting base for the card plate to pass through.

[0022] The advantages of this scheme are at least as follows: When the secondary fixing component is needed, the sliding seat is first slid to the pre-set installation position on the mounting rod via the adjustment mechanism. Then, the seeder mounting base is aligned with the claw position of the main fixing component, so that the locking groove is aligned with the claw. The drive component is activated to complete the initial fixing of the seeder by the main fixing component. The drive motor is then activated, and the drive motor drives the bidirectional screw to rotate through the transmission mechanism. Since the bidirectional screw has two threaded sections with opposite directions of rotation, the two locking plates are threadedly engaged with the two threaded sections of the bidirectional screw and slidably connected to the guide rod. Therefore, when the bidirectional screw rotates, the two locking plates will move towards each other. The two locking plates gradually pass through the locking holes on the seeder mounting base until the locking plates exit the seeder mounting base from the locking holes, completing the auxiliary locking and fixing of the seeder by the secondary fixing component.

[0023] The present invention is further configured such that the quick-release fixing mechanism further includes a pre-positioning component, the pre-positioning component including a positioning post disposed on the sliding seat and a positioning sleeve disposed on the seeder mounting seat.

[0024] The advantages of this scheme are at least as follows: before using the quick-release fixing mechanism, the seeder is initially positioned by fitting the positioning sleeve on the seeder mounting base onto the positioning post on the sliding base. This ensures that the main fixing components and secondary fixing components of the seeder mounting base and the sliding base are precisely aligned, avoiding problems caused by installation deviations that prevent the claws from properly engaging with the slots and the plates from properly engaging with the holes. This ensures the installation accuracy and fixing stability of the seeder.

[0025] The present invention is further configured such that: the adjustment mechanism includes: a lead screw and a servo motor, the lead screw is rotatably mounted on a mounting rod, the servo motor is fixed on the mounting rod, and the output end of the servo motor is connected to one end of the lead screw.

[0026] The advantages of this scheme are at least as follows: when it is necessary to adjust the row spacing of the seeder, the servo motor is started, and the output end of the servo motor is connected to one end of the lead screw, which drives the lead screw to rotate and causes the sliding seat on the lead screw to move on the lead screw, thereby achieving precise adjustment of the row spacing of the seeder.

[0027] The present invention is further configured such that: the seeder is rotatably mounted on the mounting frame, the mounting frame is connected to the quick-release fixing mechanism through the seeder mounting seat; the mounting frame is hinged to the seeder mounting seat, and an angle adjustment and locking mechanism is provided between the mounting frame and the seeder mounting seat.

[0028] The advantages of this scheme are at least as follows: the seeder is hinged to the seeder mounting base via a mounting frame and is equipped with an angle adjustment and locking mechanism, which can adjust the angle of the seeder according to actual sowing needs. At the same time, this design allows the seeder to adapt to different terrains and sowing depth requirements, improving the adaptability and flexibility of sowing.

[0029] The present invention is further configured such that the angle adjustment locking mechanism includes:

[0030] An adjusting rod, one end of which is hinged to the mounting bracket;

[0031] An oblong hole is formed on the seeder mounting base;

[0032] A fixed handle is provided, and the other end of the adjusting rod passes through the elongated hole and is threadedly connected to the fixed handle.

[0033] An elastic element is sleeved on the adjusting rod and located on the adjusting rod between the mounting frame and the seeder mounting base.

[0034] The advantages of this scheme are at least as follows: when the angle adjustment locking mechanism needs to be adjusted, the fixed handle can be loosened manually or with a tool, allowing the adjusting rod to move freely within the elongated hole. During the adjustment process, the elastic element will be stretched or compressed, providing corresponding reaction force as needed. After confirming that the seeder angle is appropriate, the fixed handle is tightened to fix the adjusting rod within the elongated hole, thereby locking the seeder angle. The design of the elastic element can provide a certain buffering effect, absorbing the vibration caused by terrain undulations during the sowing process, maintaining the stability of the seeder angle, and helping to improve the sowing quality.

[0035] The present invention is further configured such that: the mounting rod is rotatably mounted on the frame, and an angle adjustment actuator is provided between the mounting rod and the frame.

[0036] The advantages of this solution are at least as follows: the angle between the mounting rod and the frame is adjustable, allowing the seeder to adapt to different terrains and planting needs. The angle adjustment actuator can precisely adjust the angle of the mounting rod, achieving precise control of the seeder's working angle, improving sowing quality and accuracy. Furthermore, the seeder's working posture can be quickly adjusted, reducing the time spent on frequent reinstallation or adjustment of the equipment under different operating conditions, and improving operational efficiency.

[0037] The present invention is further configured such that: the angle adjustment actuator includes two electric push rods, one end of which is hinged to the frame and the other end is hinged to the mounting rod via a hinge seat, and the two electric push rods are symmetrically arranged on both sides of the mounting rod.

[0038] The advantages of this scheme are at least as follows: by using two electric push rods symmetrically arranged on both sides of the mounting rod, a stable pushing and pulling force can be provided, and the angle change of the mounting rod can be precisely controlled. At the same time, the two electric push rods work together to distribute the load, enhance the load-bearing capacity of the entire angle adjustment actuator, adapt to the torque requirements under different terrains and working conditions, and ensure the stability of the equipment under complex working conditions.

[0039] In summary, the present invention has at least the following advantages:

[0040] 1. By setting up quick-release fixing mechanism and adjustment mechanism, the installation and replacement of seeders in traditional seeders are often cumbersome, requiring multiple tools and a lot of time. The quick-release fixing mechanism and seeder mounting base design make the installation and disassembly of the seeder simple and quick, without complicated tools and long operation time, which greatly saves the time of replacing the seeder. This allows for quick switching when facing different sowing tasks and effectively improves the overall efficiency of sowing operations.

[0041] Existing seeders suffer from several inconveniences in row spacing adjustment. They either lack flexible row spacing adjustment capabilities or require complex mechanical structures and cumbersome operation. By implementing an adjustment mechanism to allow flexible row spacing adjustment, the seeder can adapt to the planting requirements of different crops and various planting patterns, such as single-row, double-row, and wide-narrow-row planting. Farmers can quickly set the appropriate row spacing according to their actual planting plan and farmland layout, avoiding the need for repeated adjustments to the seeder's position or re-preparation due to incorrect row spacing. This further ensures efficient sowing and improves agricultural production efficiency.

[0042] In existing technologies, adjusting the seeding row spacing or replacing the seeder often requires multiple people to work together and repeatedly disassemble and reassemble parts, resulting in high labor intensity. The seeder in this solution can be quickly and easily completed by the operator, from the installation and disassembly of the seeder to the adjustment of the seeding row spacing, without the need for professional training or complicated operating skills.

[0043] 2. By setting an angle adjustment locking mechanism, when it is necessary to adjust the angle adjustment locking mechanism, the fixed handle can be loosened manually or with a tool, so that the adjusting rod can move freely in the elongated hole. During the adjustment process, the elastic element will be stretched or compressed, providing the corresponding reaction force as needed. After confirming that the seeder angle is appropriate, tighten the fixed handle to fix the adjusting rod in the elongated hole, thereby locking the angle of the seeder. The design of the elastic element can provide a certain buffering effect, absorb the vibration caused by the terrain undulation during the sowing process, maintain the stability of the seeder angle, and help improve the sowing quality.

[0044] 3. By setting an angle adjustment actuator, the angle between the mounting rod and the frame is adjustable, enabling the seeder to adapt to different terrains and planting needs. The angle adjustment actuator can precisely adjust the angle of the mounting rod, achieving precise control of the seeder's working angle, improving sowing quality and accuracy. It can also quickly adjust the seeder's working posture, reducing the time spent on frequent reinstallation or adjustment under different operating conditions, thus improving work efficiency. Two electric push rods are symmetrically set on both sides of the mounting rod, providing stable push and pull forces and precisely controlling the angle change of the mounting rod. At the same time, the two electric push rods work together to distribute the load, enhancing the load-bearing capacity of the entire angle adjustment actuator, adapting to the torque requirements of different terrains and operating conditions, and ensuring the stability of the equipment under complex working conditions.

[0054] 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, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0055] 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.

[0056] Example 1

[0057] like Figure 1 , Figure 2 As shown, a multi-row electric seeder includes a walking chassis 1, a seeder 2, and a frame 3. The frame 3 is fixedly installed on the walking chassis 1. The frame 3 is also equipped with a control box and a power supply for supplying power and controlling the entire walking chassis 1 and the quick-release fixing mechanism 5. Specifically, the walking chassis 1 is preferably a triangular track type walking chassis 1. In other embodiments, it can also be a tire type walking chassis 1. A handrail frame is installed on the frame 3, and a handrail is installed on the handrail frame.

[0058] Furthermore, the frame 3 is provided with at least one mounting rod 4. The seeder 2 is detached and installed on the frame 3 through the quick-release fixing mechanism 5 and the seeder mounting base 7. The design of the quick-release fixing mechanism 5 and the seeder mounting base 7 makes the installation and removal of the seeder 2 simple and quick, without complicated tools and long operation time, which greatly saves the time of replacing the seeder 2.

[0059] like Figure 3As shown, the quick-release fixing mechanism 5 includes a sliding seat 501 and a main fixing component 502 and a secondary fixing component 503 disposed on the sliding seat 501. The sliding seat 501 is slidably mounted on the mounting rod 4 through the adjusting mechanism 6. The main fixing component 502 is used to form a main snap-fit ​​fixing with the seeder mounting seat 7, and the secondary fixing component 503 is used to form an auxiliary locking fixing with the seeder mounting seat 7, so that the seeder 2 can obtain an extremely firm fixing effect after installation. Even if the seeder encounters various complex working conditions such as bumps and vibrations during the walking operation, the seeder 2 is not easy to loosen or shift, thereby ensuring the accuracy of the sowing operation.

[0060] Furthermore, the mounting rod 4 is provided with an adjustment mechanism 6 for driving the quick-release fixing mechanism 5 to move along the length of the mounting rod 4 to adjust the row spacing. Existing seeders have many inconveniences in row spacing adjustment. They either cannot achieve flexible adjustment of row spacing or require complex mechanical structures and cumbersome operation processes. In some preferred embodiments, in order to make it easier to adjust the row spacing of the seeder 2, the adjustment mechanism 6 includes: a lead screw 601 and a servo motor 602. The lead screw 601 is rotatably mounted on the mounting rod 4, and the servo motor 602 is fixed on the mounting rod 4. The output end of the servo motor 602 is connected to one end of the lead screw 601 through a reducer. Specifically, the threads at both ends of the lead screw 601 are reversed, and the sliding seat 501 is threadedly connected to the lead screw 601.

[0061] In some other embodiments, a guide rail is provided on the mounting rod 4, and a slider that slides in cooperation with the guide rail is provided on the sliding seat 501, so that the sliding seat 501 is more stable when moving on the mounting rod 4.

[0062] During adjustment, the servo motor 602 is activated. The output of the servo motor 602 is connected to one end of the lead screw 601, driving the lead screw 601 to rotate. This causes the sliding seat 501 on the lead screw 601 to move, thereby achieving precise adjustment of the row spacing of the seeder 2. This allows the seeder to adapt to the planting requirements of different crops and different planting patterns, such as single-row, double-row, and wide-narrow-row planting. Growers can quickly set the appropriate row spacing according to their actual planting plan and farmland layout, avoiding the need to repeatedly adjust the seeder position or prepare the seeder again due to incorrect row spacing. This further ensures efficient sowing and improves agricultural production efficiency.

[0063] It is worth mentioning that, in some preferred embodiments, in order to ensure that the row spacing of the seeder 2 is more accurate when it is adjusted, numerical scale lines are laser-engraved on the mounting rod 4. The row spacing of the seeder 2 can be adjusted more intuitively through the numerical scale lines. In order to ensure that a large amount of soil does not stick to the lead screw 601 during operation, thereby affecting the adjustment of the row spacing, protective shells can also be provided at the top and bottom of the mounting rod 4. One end of the protective shell is hinged to the mounting rod 4, and the other end is fixed to the mounting rod 4 by snap-fit.

[0064] like Figure 4 As shown (refer to) Figure 7 The main fixing assembly 502 includes a drive assembly 5022 and at least two pairs of opposing jaws 5021. Each pair of jaws 5021 is hinged to the sliding seat 501 via a rotating seat 5023. The drive assembly 5022 can be an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. The drive assembly 5022 is installed inside the sliding seat 501, and its output end is hinged to one end of the jaw 5021. The main fixing assembly 502 also includes a snap-fit ​​groove 502 formed on the seeder mounting base 7 for the jaws 5021 to snap into. 4; The inner side of the claw 5021 of the main fixing component 502 is provided with anti-slip texture 10. The function of anti-slip texture 10 is to increase the friction between the claw 5021 and the locking groove 5024, which can effectively reduce the phenomenon of loosening after the claw 5021 is locked into the locking groove 5024. In addition, a torsion spring 11 is installed between the hinge end of the claw 5021 and the sliding seat 501. The function of torsion spring 11 is to ensure that the claw 5021 remains locked even if the drive component 5022 fails under the action of external force.

[0065] like Figure 5 As shown (refer to) Figure 7The secondary fixing assembly 503 includes a drive motor 5031, a bidirectional screw 5032, a transmission mechanism 5033, two clamping plates 5034, and several guide rods 5035. The drive motor 5031 is installed inside the sliding seat 501. The bidirectional screw 5032 is rotatably installed inside the sliding seat 501 and has two threaded sections with opposite directions of rotation. The guide rods 5035 are fixedly installed inside the sliding seat 501. The transmission mechanism 5033 is installed between the output end of the drive motor 5031 and the bidirectional screw 5032. The two clamping plates 5034 are threadedly engaged with the two threaded sections of the bidirectional screw 5032 and with the guide rods 5035. 35. Sliding connection; the secondary fixing component 503 also includes a snap-fit ​​hole 5036 on the seeder mounting base 7 for the snap-fit ​​plate 5034 to pass through, and a sliding hole on the mounting rod 4 for the snap-fit ​​plate 5034 to pass through. In some embodiments, in order to make the secondary fixing component 503 more secure, a limiting hole can be opened on the snap-fit ​​plate 5034. The snap-fit ​​plate 5034 with the limiting hole passes through the snap-fit ​​hole 5036 on the seeder mounting base 7. A limiting pin can be detachably installed in the limiting hole, which can prevent the snap-fit ​​plate 5034 and the bidirectional screw 5032 from loosening due to the vibration of the seeder, thereby preventing the auxiliary fixing of the secondary fixing component 503 from failing.

[0066] like Figure 6 As shown, to ensure the installation accuracy and stability of the quick-release fixing mechanism 5 between the seeder mounting base 7 and the quick-release fixing mechanism 5, in some embodiments, the quick-release fixing mechanism 5 further includes a pre-positioning component 504. The pre-positioning component 504 includes a positioning post 5041 disposed on the sliding seat 501 and a positioning sleeve 5042 disposed on the seeder mounting base 7. At least one set of pre-positioning components 504 is provided. In some preferred embodiments, two sets of pre-positioning components 504 can be provided and symmetrically installed on the sliding seat 501. When in use, the pre-positioning component 504 is activated by fitting the positioning sleeve 5042 on the seeder mounting base 7 onto the positioning sleeve 5042 on the sliding seat 501. Positioning post 5041 completes the initial positioning of seeder 2, ensuring that the main fixing component 502 and secondary fixing component 503 of seeder mounting base 7 and sliding base 501 are precisely aligned, avoiding problems caused by installation deviations such as the claw 5021 not properly engaging with the slot 5024 and the plate 5034 not properly engaging with the hole 5036. In other embodiments, a first strong magnet is provided inside the positioning sleeve 5042, and a second strong magnet that is attracted to the opposite pole of the first strong magnet is embedded at one end of the positioning post 5041. After the positioning sleeve 5042 is fitted onto the positioning post 5041, the attraction between opposite poles of the magnets makes the pre-positioning more accurate.

[0067] Example 2

[0068] like Figure 6 , Figure 7 As shown (refer to) Figure 2To adapt to different terrains and improve sowing quality, in some preferred embodiments, the seeder 2 is rotatably mounted on the mounting frame 12, which is connected to the quick-release fixing mechanism 5 via the seeder mounting base 7. The mounting frame 12 is hinged to the seeder mounting base 7, and an angle adjustment locking mechanism 8 is provided between the mounting frame 12 and the seeder mounting base 7. The angle adjustment locking mechanism 8 includes: an adjustment rod 801, one end of which is hinged to the mounting frame 12; and an elongated hole 802, which is formed on the seeder mounting base 7. A fixed handle 803 is provided, and the other end of the adjusting rod 801 passes through the elongated hole 802 and is threadedly connected to the fixed handle 803. An elastic element 804 is sleeved on the adjusting rod 801 and located on the adjusting rod 801 between the mounting frame 12 and the seeder mounting base 7. The elastic element 804 is specifically a spring. When the angle adjustment locking mechanism 8 needs to be adjusted, the fixed handle 803 is loosened manually or with a tool, so that the adjusting rod 801 can move freely in the elongated hole 802. During the adjustment process, the elastic element 804 will be stretched or compressed, providing corresponding reaction force as needed. After confirming that the angle of the seeder 2 is appropriate, the fixed handle 803 is tightened to fix the adjusting rod 801 in the elongated hole 802, thereby locking the angle of the seeder 2. The design of the elastic element 804 can provide a certain buffering effect, absorb the vibration caused by the terrain undulation during the sowing process, and maintain the stability of the angle of the seeder 2.

[0069] Mounting rod 4 is rotatably mounted on frame 3, and an angle adjustment actuator 9 is provided between mounting rod 4 and frame 3. Angle adjustment actuator 9 includes two electric push rods 901. One end of electric push rod 901 is hinged to frame 3, and the other end is hinged to mounting rod 4 through hinge seat 902. The two electric push rods 901 are symmetrically arranged on both sides of mounting rod 4. The two electric push rods 901 symmetrically arranged on both sides of mounting rod 4 can provide stable push and pull force and accurately control the angle change of mounting rod 4. At the same time, the two electric push rods 901 work together to distribute the load, thereby enhancing the load-bearing capacity of the entire angle adjustment actuator 9.

[0070] Example 3

[0071] Based on Embodiment 1 or Embodiment 2, the present invention also provides an operation method for a multi-row electric seeder.

[0072] When the seeder 2 needs to be installed, first put the positioning sleeve 5042 on the seeder mounting base 7 into the positioning post 5041 on the sliding base 501 to complete the initial positioning of the seeder 2. This ensures that the main fixing component 502 and the secondary fixing component 503 of the seeder mounting base 7 and the sliding base 501 are accurately aligned, avoiding the problem that the claw 5021 and the slot 5024, and the plate 5034 and the hole 5036 cannot be properly matched due to installation deviation.

[0073] Subsequently, the sliding seat 501 is slid to the preset installation position on the mounting rod 4 via the adjusting mechanism 6. Then, the seeder mounting seat 7 is aligned with the position of the claw 5021 of the main fixing component 502. Then, the snap-fit ​​groove 5024 on the seeder mounting seat 7 is aligned with the claw 5021. The drive component 5022 is started. The output end of the drive component 5022 pushes one end of the claw 5021, causing it to rotate around the hinge point of the rotating seat 5023. The other end of the claw 5021 gradually snaps into the snap-fit ​​groove 5024 until the anti-slip texture 10 on the inner side of the claw 5021 is tightly fitted with the snap-fit ​​groove 5024, thus completing the initial fixing of the seeder 2.

[0074] Next, the drive assembly 5022 is activated to complete the initial fixation of the seeder 2 by the main fixing assembly 502. The drive motor 5031 is then activated, and the drive motor 5031 drives the bidirectional screw 5032 to rotate through the transmission mechanism 5033. Since the bidirectional screw 5032 has two threaded sections with opposite directions of rotation, the two clamping plates 5034 are threadedly engaged with the two threaded sections of the bidirectional screw 5032 and slidably connected with the guide rod 5035. Therefore, when the bidirectional screw 5032 rotates, the two clamping plates 5034 will move towards each other. The two clamping plates 5034 gradually pass into the snap-fit ​​holes 5036 on the seeder mounting base 7 until the clamping plates 5034 exit the seeder mounting base 7 from the snap-fit ​​holes 5036, completing the auxiliary locking and fixing of the seeder 2 by the secondary fixing assembly 503.

[0075] When using the seeder, the angle adjustment locking mechanism 8 and the angle adjustment actuator 9 are adjusted according to the sowing environment to adapt to the terrain of the current sowing environment. When the angle adjustment locking mechanism 8 needs to be adjusted, the fixed handle 803 is loosened manually or with a tool, so that the adjusting rod 801 can move freely in the elongated hole 802. During the adjustment process, the elastic element 804 will be stretched or compressed, providing the corresponding reaction force as needed. After confirming that the angle of the seeder 2 is appropriate, the fixed handle 803 is tightened to fix the adjusting rod 801 in the elongated hole 802, thereby locking the angle of the seeder 2.

[0076] When adjusting the angle of the actuator 9, first check whether the connection position between the mounting rod 4 and the frame 3 is accurate. Ensure that the mounting rod 4 is mounted on the frame 3 through a suitable rotating connector (such as a bearing or shaft) and can rotate freely around its connection point with the frame 3. Then, control the two electric push rods 901 to start via the control box. When the electric push rod 901 extends, it will push the mounting rod 4 to rotate upward around its connection point with the frame 3; when the electric push rod 901 shortens, it will pull the mounting rod 4 to rotate downward around its connection point with the frame 3, thereby adjusting the seeder 2 to the appropriate sowing angle.

[0077] When adjusting the row spacing during sowing, the servo motor 602 is started via the control box. The output end of the servo motor 602 is connected to one end of the lead screw 601, driving the lead screw 601 to rotate and causing the sliding seat 501 on the lead screw 601 to move. Since the threads on the lead screw 601 are reversed, when the servo motor 602 rotates, it drives the lead screw 601 to rotate, thereby causing the two sliding seats 501 to move towards each other, thus achieving the adjustment of the row spacing.

[0078] Another method is to first adjust the row spacing of the sliding seat 501 through the adjustment mechanism 6, then fix the seeder mounting seat 7 on the mounting rod 4 through the pre-positioning component 504 and the quick-release fixing mechanism 5, and finally adjust the angle adjustment actuator 9 and the angle adjustment locking mechanism 8 according to the terrain. The specific detailed operation steps are as described above.

[0079] Compared to existing seeders that require multiple people to work together and repeatedly disassemble and reassemble parts when adjusting the seeding row spacing or replacing the seeder 2, the seeder in this solution allows operators to quickly and easily install and disassemble the seeder 2 and adjust the seeding row spacing. This enables the seeder to adapt to the planting requirements of different crops and different planting patterns, such as single row, double row, wide and narrow row, etc., without the need for professional training or complicated operating skills.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
