Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, and more specifically it relates to a quick-release fixing mechanism for a 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] In existing seeders, the seeder is typically rigidly fixed to the chassis frame with bolts. However, since seeders operate in moist soil environments for extended periods, these bolts inevitably become covered and soaked with mud. This easily leads to bolt corrosion and adhesion. When the seeder needs repair or replacement, the disassembly process is extremely laborious and time-consuming, severely impacting equipment maintenance efficiency and operational continuity. Furthermore, it makes adjusting row spacing inconvenient. Therefore, there is an urgent need for a quick-release fixing mechanism for seeders to solve these problems. Utility Model Content

[0004] In view of the problems of slow disassembly and installation and inability to quickly adjust row spacing in existing technologies, the purpose of this utility model is to provide a quick-release fixing mechanism for a seeder, which has the advantages of convenient and quick disassembly and installation of the seeder and convenient adjustment of row spacing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-release fixing mechanism for a seeder includes a mounting rod and a seeder mounting base. The mounting rod is welded from two hollow square steel pipes and several connecting blocks. One end of the mounting rod is mounted on the chassis frame. The mounting rod is provided with a quick-release fixing component for quick release of the seeder mounting base and the mounting rod.

[0007] The advantages of this solution are at least as follows: when the seeder needs to be installed, the seeder mounting base is first connected to the seeder, and then the seeder mounting base is disassembled and installed on the mounting rod through the quick-release fixing component, which makes the installation and disassembly of the seeder simple and quick, without complicated tools and long operation time, greatly saving the time of changing the seeder, so that it can be quickly switched when facing different sowing tasks, effectively improving the overall efficiency of sowing operations.

[0008] The present invention is further configured such that: the quick-release fixing assembly includes: a sliding seat and a main fixing assembly and a secondary fixing assembly disposed on the sliding seat; the sliding seat is slidably mounted on the mounting rod through an adjustment mechanism; the main fixing assembly is used to form a main snap-fit ​​fixing with the seeder mounting seat; and the secondary fixing assembly is used to form an auxiliary locking fixing with the seeder mounting seat.

[0009] The advantages of this scheme are at least as follows: the main fixing component first forms a primary snap-fit ​​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 after installation. Even when encountering various complex working conditions such as bumps and vibrations during the seeder's operation, the seeder is not easily loosened or displaced, thus 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, thereby improving the sowing quality.

[0010] 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 the 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.

[0011] The main fixing component also includes a snap-fit ​​groove formed on the seeder mounting base for the snap-fit ​​claw to engage.

[0012] The advantages of this scheme are at least as follows: when the main fixing component is needed, first align the seeder mounting base with the claw position of the main fixing component, then align the locking groove on the seeder mounting base with the claw, start the drive component, 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, and the other end of the claw gradually engages in the locking groove until the claw and the locking groove are tightly fitted, thus completing the initial fixing of the seeder.

[0013] 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;

[0014] The secondary fixing component also includes a snap-fit ​​hole formed on the seeder mounting base for the card plate to pass through.

[0015] The advantages of this scheme are at least as follows: When the secondary fixing component is needed, 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 then 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, and 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.

[0016] The present invention is further configured such that: the quick-release fixing assembly further includes a pre-positioning assembly, the pre-positioning assembly including a positioning post disposed on the sliding seat and a positioning sleeve disposed on the seeder mounting seat.

[0017] The advantages of this scheme are at least as follows: before using the quick-release fixing components, 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.

[0018] The present invention is further provided with an adjustment mechanism on the mounting rod for driving the quick-release fixing assembly to move along the installation length direction to adjust the sowing row spacing.

[0019] The advantages of this scheme are at least as follows: The adjustable row spacing allows for flexible adjustment of the seeding mechanism, enabling the seeder to adapt to different crop planting requirements and planting patterns, such as single-row, double-row, and wide-narrow-row planting. Farmers can quickly set the 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 seeding and improves agricultural production efficiency.

[0020] 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 the connecting block of the 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.

[0021] 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.

[0022] The present invention is further configured such that both ends of the lead screw are provided with threads, and the threads at both ends are rotated in opposite directions.

[0023] The present invention is further configured such that the inner side of the claw of the main fixing component is provided with anti-slip texture.

[0024] The advantages of this solution are at least as follows: the anti-slip texture on the inner side of the claw provides strong clamping force and anti-slip effect when it engages 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.

[0025] The present invention is further configured such that a torsion spring is installed between the hinge end of the claw and the sliding seat.

[0026] The advantage of this solution is at least that when one of the drive components fails, the reaction force of the torsion spring ensures that the pawl remains locked, preventing it from becoming loose due to the failure of the drive component.

[0027] In summary, this utility model has at least the following advantages:

[0028] 1. By setting up quick-release fixing components, the main fixing component first forms a primary snap-fit ​​fixing with the seeder mounting base, providing stable support and initial fixing effect for the seeder. The secondary fixing component further forms an auxiliary locking fixing with the seeder mounting base, so that the seeder 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 seeder's movement 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.

[0029] 2. By incorporating an adjustment mechanism, the sowing row spacing can be flexibly adjusted, allowing 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 sowing. Growers can quickly set the appropriate sowing 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 mismatched row spacing. This further ensures efficient sowing and improves agricultural production efficiency. Attached Figure Description

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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 this utility model and the features within them can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1

[0039] A quick-release fixing mechanism for a seeder includes a mounting rod 1 and a seeder mounting base 2. The mounting rod 1 is welded from two hollow square steel pipes 101 and several connecting blocks 102. One end of the mounting rod 1 is mounted on the chassis frame. The mounting rod 1 is provided with a quick-release fixing component 3 for quick release of the seeder mounting base 2 and the mounting rod 1. The design of the quick-release fixing component 3 and the seeder mounting base 2 makes 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.

[0040] The quick-release fixing component 3 includes: a sliding seat 301 and a main fixing component 302 and a secondary fixing component 303 disposed on the sliding seat 301. The sliding seat 301 is mounted on the mounting rod 1. The main fixing component 302 is used to form a main snap-fit ​​fixing with the seeder mounting seat 2, and the secondary fixing component 303 is used to form an auxiliary locking fixing with the seeder mounting seat 2. The main fixing component 302 is used to form a main snap-fit ​​fixing with the seeder mounting seat 2, and the secondary fixing component 303 is used to form an auxiliary locking fixing with the seeder mounting seat 2, so as to ensure that the fixing between the seeder mounting seat 2 and the mounting rod 1 is more secure.

[0041] The main fixing assembly 302 includes a drive assembly 3022 and at least two pairs of opposing claws 3021. Each pair of claws 3021 is hinged to the sliding seat 301 via a rotating seat 3023. The drive assembly 3022 is installed inside the sliding seat 301, and the output end of the drive assembly 3022 is hinged to one end of the claw 3021. The drive assembly 3022 can be an electric cylinder, a hydraulic cylinder, a hydraulic cylinder, or an electric push rod. The main fixing assembly 302 also includes a snap-fit ​​groove 3024 formed on the seeder mounting base 2 for the claws 3021 to snap into. It is worth mentioning that, in order to enhance the fixing effect between the claw 3021 and the locking groove 3024, anti-slip texture 5 is provided on the inner side of the claw 3021 of the main fixing component 302. When the anti-slip texture 5 cooperates with the locking groove 3024 of the seeder mounting base 2, it can provide strong clamping force and anti-slip effect, ensuring that the seeder will not loosen even if it is subjected to various external forces during operation. A torsion spring 6 is installed between the hinge end of the claw 3021 and the sliding seat 301. The design of the torsion spring 6 is that when one of the drive components 3022 fails, the reaction of the torsion spring 6 can ensure that the claw 3021 still maintains the clamped state, ensuring that the claw 3021 will not become unstable due to the failure of the drive component 3022.

[0042] The secondary fixing assembly 303 includes a drive motor 3031, a bidirectional screw 3032, a transmission mechanism 3033, two clamping plates 3034, and several guide rods 3035. The drive motor 3031 is installed inside the sliding seat 301. The bidirectional screw 3032 is rotatably installed inside the sliding seat 301 and has two threaded sections with opposite directions of rotation. The transmission mechanism 3033 is installed between the output end of the drive motor 3031 and the bidirectional screw 3032. The two clamping plates 3034 are threadedly engaged with the two threaded sections of the bidirectional screw 3032 and are slidably connected to the guide rods 3035. The secondary fixing assembly 303 also includes a snap-fit ​​hole 3036 opened on the seeder mounting base 2 for the clamping plates 3034 to pass through.

[0043] The quick-release fixing component 3 also includes a pre-positioning component 304. The pre-positioning component 304 includes a positioning post 3041 set on the sliding seat 301 and a positioning sleeve 3042 set on the seeder mounting base 2. Before using the quick-release fixing mechanism, the positioning sleeve 3042 on the seeder mounting base 2 is fitted onto the positioning post 3041 on the sliding seat 301 to complete the initial positioning of the seeder mounting base 2. This ensures that the main fixing component 302 and the secondary fixing component 303 of the seeder mounting base 2 are accurately aligned with the sliding seat 301, avoiding the problem that the claw 3021 and the slot 3024, and the plate 3034 and the hole 3036 cannot be properly matched due to installation deviation. This ensures the installation accuracy and fixing stability of the seeder mounting base 2. The seeder is rotatably mounted on the mounting frame, and the mounting frame is fixedly connected to the seeder mounting base 2.

[0044] Example 2

[0045] In some embodiments, in order to facilitate the adjustment of the row spacing of the seeder, the mounting rod 1 is also provided with an adjustment mechanism 4 for driving the quick-release fixing assembly 3 to move along the installation length direction to adjust the sowing row spacing.

[0046] The adjustment mechanism 4 includes a lead screw 401 and a servo motor 402. The lead screw 401 is rotatably mounted on the connecting block 102 of the mounting rod 1. The servo motor 402 is fixed on the mounting rod 1, and its output end is connected to one end of the lead screw 401. Both ends of the lead screw 401 are threaded, and the threads at both ends rotate in opposite directions. Furthermore, a sliding seat 301 is threadedly connected to the lead screw 401 and slidably mounted on the mounting rod 1. In some other preferred embodiments, the adjustment mechanism 4 may also consist of a rack mounted at the bottom of the mounting rod 1 and a motor mounted inside the sliding seat 301. The output end of the motor is equipped with a gear that meshes with the rack. During adjustment, the motor is activated, causing the gear to move on the rack, thereby adjusting the row spacing of the seeder. The adjusting mechanism 4 can also be a stroke cylinder with a long displacement. The cylinder is installed on the side wall of the connecting block 102, and the output end of the cylinder is installed on one end of the sliding seat 301. The sliding seat 301 is slidably installed on the mounting rod 1. When adjusting the row spacing, the stroke cylinder is activated, and the stroke cylinder drives the sliding seat 301 to move on the mounting rod 1, thereby achieving the purpose of adjusting the row spacing of the seeder.

[0047] To ensure more stable movement of the sliding seat 301 on the mounting rod 1, in some preferred embodiments, the mounting rod 1 is provided with a guide rail, and the sliding seat 301 is provided with a slider that matches the guide rail, making the sliding seat 301 more stable when moving. In other embodiments, the mounting rod 1 is also provided with a protective shell to prevent dirt from sticking to the lead screw 401. The protective shell can be made of transparent material, with one end hinged to the mounting rod 1 and the other end fixed to the mounting rod 1 by a snap-fit.

[0048] In this embodiment, when adjusting the row spacing, the adjustment mechanism 4 starts the servo motor 402. The output end of the servo motor 402 is connected to one end of the lead screw 401, driving the lead screw 401 to rotate and causing the sliding seat 301 on the lead screw 401 to move on the lead screw 401. This achieves precise adjustment of the row spacing of the seeder, enabling the seeder to adapt to the planting requirements of different crops and different planting modes, such as single row, double row, wide and narrow row and other planting methods.

[0049] Example 3

[0050] Based on Embodiment 1 or Embodiment 2, this utility model also provides a method for using a quick-release fixing mechanism for a seeder. When the seeder needs to be installed, the positioning sleeve 3042 on the seeder mounting base 2 is first put into the positioning post 3041 on the sliding base 301 to complete the initial positioning of the seeder. This ensures that the main fixing component 302 and the secondary fixing component 303 of the seeder mounting base 2 and the sliding base 301 are precisely aligned, avoiding the problem that the claw 3021 and the slot 3024, and the plate 3034 and the hole 3036 cannot be properly matched due to installation deviation.

[0051] Subsequently, the sliding seat 301 is slid to the pre-set installation position on the mounting rod 1 via the adjusting mechanism 4. Then, the seeder mounting seat 2 is aligned with the position of the claw 3021 on the main fixing component 302. Then, the locking groove 3024 on the seeder mounting seat 2 is aligned with the claw 3021. The drive component 3022 is started. The output end of the drive component 3022 pushes one end of the claw 3021, causing it to rotate around the hinge point of the rotating seat 3023. The other end of the claw 3021 gradually engages in the locking groove 3024 until the anti-slip texture 5 on the inner side of the claw 3021 is tightly fitted with the locking groove 3024, thus completing the initial fixing of the seeder.

[0052] When adjusting the row spacing during sowing, the servo motor 402 is started by controlling the control box. The output end of the servo motor 402 is connected to one end of the lead screw 401, driving the lead screw 401 to rotate and causing the sliding seat 301 on the lead screw 401 to move on the lead screw 401. Since the threads on the lead screw 401 are set in opposite directions, when the servo motor 402 rotates, it drives the lead screw 401 to rotate, thereby causing the two sliding seats 301 to move towards each other, thus achieving the adjustment of the row spacing.

[0053] The main fixing component 302 and the secondary fixing component 303 can be used in different sequences: first, the secondary fixing component 303 is used to fix the device, and then the main fixing component 302 is used to fix it. Alternatively, the main fixing component and the secondary fixing component can be activated simultaneously to fix the seeder mounting base 2. When adjusting the row spacing, the sliding seat 301 can be adjusted first when the seeder is not installed, and then the seeder mounting base 2 can be fixed by the quick-release fixing component 3.

[0054] The quick-release fixing component 3 in this solution allows operators to quickly install and remove the seeder and easily adjust the seeding row spacing, from the installation and removal of the seeder to the adjustment of the seeding row spacing. This avoids the problem in existing seeders where multiple people need to work together and repeatedly disassemble and reassemble parts when adjusting the seeding row spacing or replacing the seeder.

[0055] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
