Description

Technical Field

[0001] This invention relates to the field of rice transplanter technology, and in particular to an adjustable seedling box for wide and narrow row rice transplanters. Background Technology

[0002] As a major food crop in China, the planting method of rice directly affects the yield and quality of the grain. One such planting technique is wide-narrow row rice transplanting. This technique optimizes the arrangement of plants in the field, achieving alternating wide and narrow rows. This effectively improves ventilation and light penetration in the field, reducing the risk of pests, diseases, and lodging. Studies have shown that this technique can significantly increase rice yield, with an increase rate of over 5%.

[0003] Furthermore, traditional manual rice transplanting methods can no longer meet the demands of high-efficiency, large-scale production. Therefore, mechanized rice transplanting technology has become the key to improving the efficiency and quality of rice cultivation, while wide-narrow row transplanting technology requires rice transplanters to be able to adapt to different row spacing requirements in order to achieve the planting requirements of wide and narrow rows.

[0004] However, existing wide-narrow row rice transplanters have certain limitations, as known to the inventors. Most models' seedling box designs are only suitable for specific seedling tray models, lacking flexibility and limiting the widespread application of wide-narrow row transplanters. Furthermore, traditional wide-narrow row rice transplanter seedling feeding devices often encounter problems such as jamming or excessive slippage of the seedling tray during operation. These problems not only affect transplanting efficiency but may also damage seedlings, impacting rice growth and yield. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide an adjustable seedling box for a wide-narrow row rice transplanter to solve the problems existing in the prior art and realize flexible adjustment of the spacing between the seedling tray slide rails and the number of sowing rows.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6 As shown, this embodiment provides an adjustable seedling tray for a wide-narrow row rice transplanter, including a frame 1 and a seedling tray adjustment mechanism and a transmission mechanism mounted on the frame 1; wherein, the frame 1 is mounted on the rear side of the rice transplanter along the traveling direction, the transmission mechanism includes a conveyor belt 7 that conveys the seedling tray along the direction away from the traveling direction of the rice transplanter, the conveying surface of the conveyor belt 7 gradually slopes downward from its input end to its output end, and the frame 1 is provided with a drive assembly for driving the conveyor belt 7; the seedling tray adjustment mechanism includes at least one first slide rail 3 mounted on the frame 1, and the first slide rail 3 is located at the input end and / or output end of the conveyor belt 7, and along the direction away from the traveling direction of the rice transplanter. Extending horizontally perpendicular to the direction of the rice transplanter's movement, the first slide rail 3 is equipped with multiple second slide rails 4, each located above the conveying surface. Each second slide rail 4 extends along the conveying direction of the conveying surface and is movably mounted on the first slide rail 3 along the direction of its extension. The seedling tray is confined between corresponding pairs of second slide rails 4 during transport to prevent it from sliding perpendicular to the direction of the conveyor belt 7 during its descent. Before transplanting, the appropriate number of second slide rails 4 is installed according to the required number of rows to be sown. The spacing between the corresponding pairs of second slide rails 4 is then determined based on the size of the seedling tray, allowing for flexible adjustment of the tray rail spacing and the number of rows to be sown. Preferably, both ends of the first slide rail 3 are connected to slide rail support plates. A fixing plate 2 is continuously connected between the slide rail support plate and the frame 1, preferably using bolts, to mount the first slide rail 3 onto the frame 1.

[0032] In this embodiment, the seedling tray adjustment mechanism includes two first slide rails 3, which are parallel to each other and are respectively set at the input and output ends of the conveyor belt 7, so that the two ends of the second slide rail 4 can be movably installed on the two first slide rails 3, thereby ensuring that the second slide rail 4 is more stable during the transplanting operation and avoiding affecting the stability of the seedling tray during movement.

[0033] In one specific embodiment, multiple guide rail clamps 12 are movably mounted on the first slide rail 3, with the guide rail clamps 12 on the two first slide rails 3 corresponding to each other. Each guide rail clamp 12 is equipped with a first magnet assembly 13. Two spaced-apart second magnet assemblies are mounted on the second slide rail 4. The two second magnet assemblies are respectively attracted to the corresponding first magnet assemblies 13 on the two first slide rails 3, so that the second slide rail 4 is magnetically attracted and fixed to the first slide rail 3 by the first magnet assemblies 13 and the second magnet assemblies. The guide rail clamps 12 can move on the first slide rail 3 to complete the position adjustment of the second slide rail 4 on the first slide rail 3. The first magnet assemblies 13 and the second magnet assemblies facilitate the assembly and disassembly of the first slide rail 3 and the second slide rail 4. Specifically, to facilitate the assembly and disassembly of the first slide rail 3 and the second slide rail 4, it is preferable that the first magnet assembly 13 is installed at the top position of the guide rail clamp 12, and the second magnet assembly is installed at the bottom position of the second slide rail 4.

[0034] In this embodiment, the first magnet assembly 13 is an electromagnet assembly, and the second magnet assembly is a permanent magnet assembly. By energizing the first magnet assembly 13, the first magnet assembly 13 and the second magnet assembly are attracted to each other. By de-energizing the second magnet assembly, the attraction between the first magnet assembly 13 and the second magnet assembly is easily broken, thereby facilitating the picking and placing of the second slide rail 4.

[0035] In one specific embodiment, the bottom of the conveying surface is supported by multiple sets of transmission rollers 10. Each set of transmission rollers 10 is arranged at equal intervals along the conveying direction of the conveying surface. The transmission rollers 10 extend in a direction perpendicular to the conveying direction of the conveying surface, and their two ends are respectively rotatably mounted on the frame 1 so as to support the conveying surface through the transmission rollers 10, thereby completing the support and conveying of the seedling tray. Preferably, both ends of the transmission rollers 10 are provided with bearing seats 9 mounted on the frame 1, and each bearing seat 9 is equipped with a bearing that rotatably cooperates with both ends of the transmission rollers 10.

[0036] In one specific embodiment, the drive assembly includes a drive motor 14 mounted on a frame 1. The output shaft 15 of the drive motor 14 is coaxially sleeved with a drive gear 16. The drive gear 16 meshes with a driven gear 18. The driven gear 18 is connected to a transmission gear 17 that is coaxial with and synchronously drives the drive gear 18. Preferably, a gear transmission rod 20 coaxial with the driven gear 18 is connected to the shaft center of the driven gear 18. The gear transmission rod 20 is rotatably mounted on the frame 1, and the transmission gear 17 is coaxially sleeved and fixed on the gear transmission rod 20. A rack 11 that meshes with the transmission gear 17 is provided on the inner peripheral wall of the conveyor belt 7, so as to drive the rack 11 and the conveyor belt 7 to move using the transmission gear 17. Specifically, the conveyor belt 7 and the rack 11 are in a ring structure. The conveyor belt 7 is sleeved on the transmission gear 17 through the rack 11, so as to complete the precise driving of the conveyor belt 7 under the drive of the transmission gear 17.

[0037] In one embodiment, the conveyor belt 7 is equipped with two sets of drive assemblies. Both drive assemblies are located at either the input or output end of the conveyor belt 7 along its conveying direction. The drive motors 14 of the two drive assemblies are distributed on both sides of the conveyor belt 7 along a direction perpendicular to its conveying direction. The two drive assemblies share the same gear transmission rod 20, which is located on the inner circumference of the conveyor belt 7. Both ends of the gear transmission rod 20 extend beyond both sides of the conveyor belt 7 and are respectively connected to the corresponding drive gear 17 and driven gear 18. The two ends of the gear transmission rod 20 pass through the drive gear 17 and driven gear 18 and are rotatably mounted on the frame 1. In another embodiment, the conveyor belt is equipped with four sets of drive assemblies. Two drive assemblies are located at the input end of the conveyor belt 7 and distributed on both sides of the conveyor belt 7 along a direction perpendicular to its conveying direction. The other two drive assemblies are located at the output end of the conveyor belt 7 and distributed on both sides of the conveyor belt 7 along a direction perpendicular to its conveying direction.

[0038] Before the rice transplanter starts working, the parameters can be set by the controller. After the transplanting mechanism rotates a number of times, the seedling tray is placed on the conveying surface of the conveyor belt 7 and the rice transplanter starts working. After the transplanting mechanism rotates a number of times, the drive motor 14 drives the drive gear 16 to rotate at a certain angle through its output shaft 15. The drive gear 16 drives the driven gear 18 to rotate. The driven gear 18 drives the transmission gear 17 to rotate through the gear transmission rod 20. The transmission gear 17 drives the conveyor belt 7 to convey the seedling tray, which can avoid problems such as jamming and excessive feeding during the traditional structure.

[0039] In one specific embodiment, the frame 1 is provided with a mudguard located at the bottom of the conveyor belt 7. The drive motor 14 is installed at the bottom of the mudguard, and the mudguard has a notch for the drive gear 16 and the driven gear 18 to mesh. A protective cover 8 is installed on the mudguard to cover the drive motor 14 and the outer periphery of the notch, so that the drive motor 14 and the notch are covered inside the protective cover 8. The drive gear 16 is located inside the protective cover 8 and is coaxially fixedly connected to the output shaft 15 of the drive motor. The driven gear 18 is located above the mudguard and meshes with the drive gear 16 through the notch. Thus, the drive assembly and the conveyor belt 7 are protected by the mudguard and the protective cover 8 to prevent mud and sand from entering and affecting the conveyor belt 7 for seedling delivery.

[0040] In one specific embodiment, an anti-detachment frame 6 is installed on the frame 1. The anti-detachment frame 6 is located on the side of the second slide rail 4 away from the conveyor belt 7 and presses against the top of the seedling tray, slidingly engaging with the seedling tray. During the transplanting operation, the anti-detachment frame 6 can press against the top of the seedling tray to prevent the seedling tray from falling off due to bumps, and the sliding engagement with the top of the seedling tray can avoid restricting the movement of the seedling tray. Preferably, two baffles 19 are installed on the frame 1. The two baffles 19 are installed on both sides of the conveyor belt 7 along the direction perpendicular to the direction of the rice transplanter's travel, and the baffles 19 extend along the conveying direction of the conveyor belt 7. The anti-detachment frame 6 is installed between the two baffles 19.

[0041] In one specific embodiment, a guide frame 5 is provided at the position of the anti-detachment frame 6 corresponding to the input end of the conveyor belt 7. The guide frame 5 extends upward gradually in a direction away from the conveying direction of the conveyor belt 7, so that the seedling tray can enter between the anti-detachment frame 6 and the conveyor belt 7 through the guide frame 5. Preferably, the anti-detachment frame 6 includes a plurality of anti-detachment rods that cover the top of the seedling tray. Each anti-detachment rod extends along the conveying direction of the conveying surface and is evenly distributed in a direction perpendicular to the conveying surface, so that the anti-detachment rods can both cover the seedling tray and avoid obstructing it during the conveying process.

[0042] The entire device is movably mounted on the first slide rail 3 via the second slide rail 4. With the coordinated work of the drive assembly and the conveyor belt 7, it can not only improve the adaptability and flexibility of rice transplanting operations, but also ensure the stable transmission of the seedling tray during the transplanting process, avoiding jamming and excessive slippage, thereby improving the accuracy and efficiency of rice transplanting and meeting the technical requirements of wide and narrow row planting.

[0043] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
