Description

Technical Field

[0001] This invention relates to the field of rice transplanting equipment technology, and in particular to a rice transplanting device that integrates the function of quantitative deep application of enzyme microbial fertilizer. Background Technology

[0002] Existing rice transplanting devices are the core equipment in the mechanized rice planting process. They are mainly used for transplanting seedlings in paddy fields. The walking mechanism drives the transplanting actuators to insert the seedlings at a fixed distance. Most devices are equipped with seedling storage and delivery components to maintain continuous operation. In large-scale rice planting, they can effectively reduce the intensity of manual labor and improve the overall efficiency of transplanting operations.

[0003] In practical applications, existing rice transplanting devices have room for improvement in the coordination between batch temporary storage of seedlings and quantitative feeding. The posture stability of the seedlings during the falling process is insufficient, which can easily affect the consistency of subsequent transplanting. As the seedlings gradually thin out during the operation, they are prone to deviation during the adjustment of seedling positions, and the positioning accuracy of seedlings at subsequent transplanting positions is easily interfered with. To address this, we propose a rice transplanting device that integrates the function of quantitative deep application of enzyme microbial fertilizer. Summary of the Invention

[0007] As a preferred embodiment of the present invention, the limiting structure includes a baffle fixedly installed on the side of the work frame, and a second support plate rotatably installed on the inner side of the work frame.

[0008] As a preferred embodiment of the present invention, the inner side of the work frame is provided with an installation cavity, the inner side of the installation cavity is provided with a rotating cavity, a rotating shaft is rotatably installed inside the rotating cavity, a torsion spring is fixedly installed on the end face of the rotating shaft, the end of the torsion spring away from the rotating shaft is fixedly installed inside the rotating cavity, and a second support plate is fixedly installed inside the rotating shaft.

[0009] As a preferred embodiment of the present invention, the transverse plate has a sliding groove on its side, and the pushing structure includes an extrusion block slidably installed inside the sliding groove. The extrusion block is U-shaped, and a sliding cavity is provided inside the extrusion block. A first extrusion rod is slidably installed inside the sliding cavity. A second spring is fixedly installed at equal intervals on the bottom side of the first extrusion rod. A first groove is provided in the center of the third extrusion rod. A second extrusion rod is fixedly installed on the side of the first extrusion rod, penetrating the first groove. A second connecting block is fixedly installed inside the first groove. The second connecting block is a trapezoidal rod.

[0010] As a preferred embodiment of the present invention, mounting seats are fixedly installed on the sides of both extrusion blocks, a servo motor is fixedly installed on the side of the transverse plate, and a threaded rod is fixedly installed on the output end of the servo motor. The threaded rod is threadedly connected to the inside of the two mounting seats, and the internal threads of the two mounting seats have opposite directions.

[0011] As a preferred embodiment of the present invention, the extrusion structure includes a first connecting block fixedly installed on the upper side of the sliding plate, an extrusion column fixedly installed on the upper side of the first connecting block, and one end of the extrusion column extending to the side of the second support plate.

[0012] As a preferred embodiment of the present invention, a connecting rod is fixedly installed on the side of the extrusion column, and a pushing rod is fixedly installed at one end of the connecting rod, with one end of the pushing rod extending to the inner side of the third extrusion rod.

[0013] As a preferred embodiment of the present invention, the elastic structure includes a fixed block fixedly installed on the side of the transverse plate, a sliding column slidably installed inside the fixed block, a third extrusion rod fixedly installed at one end of the sliding column, a protrusion fixedly installed at the other end of the sliding column, a first spring fixedly installed on the end face of the protrusion, and the other end of the first spring fixedly installed on the side of the fixed block.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention uses a baffle and a second support plate in the limiting structure to provide bottom support and lateral constraint for the seedlings above the working frame, achieving stable temporary storage and quantitative separation of batch seedlings. The number of seedlings fed in a single batch can be maintained within a stable range, preventing seedlings from scattering randomly. Through the cooperation of a torsion spring and a rotating shaft, the second support plate can rotate to open the feeding channel when squeezed, and automatically rotate back to its original position after the squeezing pressure disappears, continuously supporting the remaining seedlings above and ensuring the consistency of the feeding amount each time. The sliding plate carries the squeezing structure downward, causing the squeezing column to simultaneously squeeze the second support plate to rotate and open the feeding channel. At the same time, the pushing rod pushes the third squeezing rod in advance to eliminate spatial interference of the seedlings descending. Through the linkage and cooperation of the sliding plate, squeezing structure, limiting structure, and elastic structure, the timing of the seedling feeding process is automatically connected. The seedlings fall smoothly to the drag plate position with the sliding plate, and the seedling posture is stable throughout the process, reducing lodging and deviation, and providing a reliable foundation for subsequent precise transplanting.

[0015] 2. This invention utilizes a rolling wheel that rotates synchronously with the device's movement, directly converting the device's kinetic energy into the driving force for transplanting rice seedlings. This eliminates the need for a separate transplanting drive motor, simplifying the device's power system structure. A transmission structure consisting of a first toothed disc, a chain, and a second toothed disc synchronously transmits the rotation of the rolling wheel to the rotation center of the rotating connecting rod, ensuring a fixed match between the frequency of transplanting and the device's speed. The rotating connecting rod drives the plug to perform a rotary transplanting action, allowing the plug to pass through the transplanting groove on the slide to transplant the seedlings into the soil. Through the coordination of the rolling wheel, transmission structure, rotating connecting rod, and plug, the transplanting action and the device's speed are adaptively matched, resulting in uniform and stable plant spacing. Simultaneously, the fixed rotation stroke of the plug ensures consistent transplanting depth, achieving a stable fixed-depth transplanting effect and improving the uniformity of rice growth and survival rate after transplanting.

[0016] 3. This invention utilizes the squeezing block in the pushing structure to slide laterally along the chute, which can drive the seedlings to gather towards the central planting position. This adapts to the need for adjusting the position as the seedlings gradually thin out during operation, eliminating the need for manual seedling positioning. Through the cooperation of the second squeezing rod and the second connecting block of the trapezoidal structure, as the squeezing block moves towards the center, the third squeezing rod is first pushed outward by the inclined surface, releasing the clamping constraint on the seedlings before the seedlings are moved horizontally. This avoids damage or lodging of the seedlings due to clamping friction during the movement. The cooperation of the second spring and the first squeezing rod provides a buffer margin for the pushing process of the second squeezing rod. After the second squeezing rod passes the second connecting block, the tension of the first spring in the elastic structure drives the third squeezing rod to automatically reset, re-clamping and fixing the seedlings. Through the cooperation of the pushing structure, the third squeezing rod, and the elastic structure, the loosening, pushing, and re-clamping processes during seedling gathering are seamlessly connected. After gathering, the seedlings are accurately positioned, effectively ensuring the planting accuracy of the central planting trough.

[0017] 4. This invention uses a telescopic mechanism to drive a sliding plate to slide up and down along a transverse plate, enabling automatic transport of seedlings from the seedling storage station to the transplanting station. The extrusion structure moves synchronously with the sliding plate, simultaneously completing two actions: opening the limiting structure for material feeding and the third extrusion rod repositioning. The reciprocating lateral movement of the transverse plate adjusts the lateral position of the seedlings. Combined with the rotating transplanting action of the plug, continuous multi-station transplanting operations with four transplanting slots can be achieved. The overall movement of the sliding plate, extrusion structure, limiting structure, elastic structure, and pushing structure reduces the number of independent drives in the device, ensuring tight coordination between actions and a smooth workflow. This also reduces the control complexity and failure rate of the device, guaranteeing the stability of the entire seedling transport, positioning, and transplanting process, and improving the overall efficiency and reliability of the transplanting operation.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figures 1 to 9As shown, a rice transplanting device integrating quantitative deep application of enzyme microbial fertilizer includes a fixed frame 111. A connecting frame 113 is fixedly installed at one end of the fixed frame 111, and a handrail 114 is fixedly installed at the end of the connecting frame 113 away from the fixed frame 111. An installation frame 112 is fixedly installed at the end of the fixed frame 111 away from the connecting frame 113. A fixed material discharge frame 311 is provided above the fixed frame 111, and a first support plate 312 is fixedly installed above the material discharge frame 311. A reciprocating transverse plate 313 is provided on the first support plate 312. A sliding plate 316 is fixedly installed on the side of the 313. Four rice planting slots 317 are provided on the side of the sliding plate 316. A rotating roller 211 is installed on the connecting frame 113. A rotating connecting rod 215, which rotates synchronously with the roller 211, is provided on the side of the mounting frame 112 at the corresponding position of the rice planting slots 317. A transmission structure is provided between the roller 211 and the rotating connecting rod 215. A plug 216 is fixedly installed at the output end of the rotating connecting rod 215. A working frame 314 is installed at the center of the side of the discharge frame 311. The working frame 314 is equipped with a connector to the working frame 31. The upper part of the rice paddy has a limiting structure to block it. Two sliding plates 315 are slidably installed on the transverse plate 313. Side plates 318 are provided on both sides and at the center of the two sliding plates 315. The side plates 318 are fixedly installed on the side of the transverse plate 313. The sides of the sliding plates 315 are provided with a pressing structure. Elastic structures are provided on both sides of the transverse plate 313 at the lower position corresponding to the work frame 314. The output ends of the two elastic structures are fixedly installed with a third pressing rod 415. Two pushing structures are slidably installed on the side of the transverse plate 313. The transmission structure includes a rotating mechanism mounted on the roller. A first gear 212 is located at the center of the drive wheel 211. A second gear 213, which is compatible with the first gear 212, is fixedly installed at the center of the mounting bracket 112. A chain 214 is connected to the first gear 212 and the second gear 213. The second gear 213 is fixedly connected to the rotation center of the rotating connecting rod 215. A second groove 611 is provided on the side of the transverse plate 313. A connecting plate 612 is fixedly installed on the upper side of the sliding plate 315. A telescopic mechanism 613 is fixedly installed on the side of the transverse plate 313. The output end of the telescopic mechanism 613 is fixedly installed on the side of the connecting plate 612.

[0022] More specifically, in the initial state, the sliding plate 315 is positioned above the work frame 314, and the entire batch of rice seedlings to be transplanted is piled on the side of the sliding plate 315. The rice seedlings are stably held in the temporary storage position by the support and lateral constraint of the limiting structure. When it is necessary to transfer the rice seedlings to the transplanting position, the sliding plate 315 actively slides downwards along the transverse plate 313, simultaneously driving the compression structure on its side downwards. During the downward movement of the compression structure, a compression force is applied to the limiting structure, causing the limiting structure to release its support constraint on the bottom of the rice seedlings. After the supporting component of the limiting structure rotates, it interacts with the sliding plate 315. The sides together form a continuous downward channel, allowing the rice seedlings to move smoothly downwards with the sliding plate 315. Once the sliding plate 315, carrying the rice seedlings, has completely passed the limiting structure, the limiting structure loses its squeezing force and automatically resets, re-supporting and constraining the remaining rice seedlings above. Simultaneously, as the sliding plate 315 descends, the squeezing structure moves downwards and squeezes the third squeezing rod 415, causing it to retract away from the seedlings, preventing it from interfering with the downward path of the rice seedlings. After the sliding plate 315, carrying the rice seedlings, moves to the corresponding position on the drag plate 316, the sliding plate 315... The sliding plate 315 slides upwards to return to its initial position. At this time, the extrusion structure moves upwards synchronously with the sliding plate 315, canceling the extrusion action on the third extrusion rod 415. The elastic structure pulls the third extrusion rod 415 inwards to return to its original position. The third extrusion rod 415 forms an extrusion fixation on the rice seedlings from the side, completing the seedling positioning. Before transplanting, the transverse plate 313 moves reciprocally along the first support plate 312 to adjust the alignment between the seedlings and the transplanting position. The operator holds the handle 114 and pushes the device forward, causing the rolling wheel 211 to rotate synchronously. The rolling wheel 211 transmits power to the rotating connecting rod 215 through the transmission structure, driving the... The rotating connecting rod 215 rotates synchronously, and during the rotation of the rotating connecting rod 215, it drives the plug 216 to rotate, so that the plug 216 passes through the transplanting groove 317 and inserts the rice seedlings into the soil, completing the fixed-depth transplanting operation. As the transplanting operation continues, the rice seedlings on the drag plate 316 gradually become sparse. At this time, the two sets of pushing structures first squeeze the third squeezing rod 415 to move outward, and then drive the rice seedlings to gather towards the center of the device. When the seedlings move to the preset position, the pushing stops, and the third squeezing rod 415 returns to its original position inward and squeezes and fixes the rice seedlings. The device can then continue to carry out the transplanting operation through the two middle transplanting grooves 317.

[0023] like Figure 3 , Figure 6 and Figure 7As shown, specifically, the limiting structure includes a baffle 321 fixedly installed on the side of the work frame 314, a second support plate 326 rotatably installed on the inner side of the work frame 314, an installation cavity 322 opened on the inner side of the work frame 314, a rotating cavity 323 opened on the inner side of the installation cavity 322, a rotating shaft 324 rotatably installed inside the rotating cavity 323, a torsion spring 325 fixedly installed on the end face of the rotating shaft 324, one end of the torsion spring 325 away from the rotating shaft 324 fixedly installed on the inner side of the rotating cavity 323, and the second support plate 326 fixedly installed on the inner side of the rotating shaft 324.

[0024] More specifically, the baffle 321 and the second support plate 326 cooperate to form a dual constraint of lateral obstruction and bottom support for the rice seedlings above the working frame 314, so that a batch of seedlings are stably stored in the inner area of ​​the working frame 314. When the extrusion structure applies downward extrusion force to the second support plate 326, the second support plate 326 rotates downward around the rotation axis 324. When it rotates to the 90-degree position, the plate surface of the second support plate 326 is flush with the side of the sliding plate 315. Together, they form a downward movement channel for the rice seedlings, which are transported downward with the sliding plate 315. During the downward movement of the rice seedlings, the lateral obstruction of the baffle 321 realizes the quantitative feeding and transportation of the rice seedlings.

[0025] like Figure 4 , Figure 8 and Figure 9 As shown, specifically, the transverse plate 313 has a sliding groove 511 on its side. The pushing structure includes a pressing block 512 slidably installed inside the sliding groove 511. The pressing block 512 is U-shaped, and a sliding cavity 513 is opened inside the pressing block 512. A first pressing rod 514 is slidably installed inside the sliding cavity 513. A second spring 515 is fixedly installed at equal intervals on the bottom side of the first pressing rod 514. A first groove 517 is opened in the center of the third pressing rod 415. A second pressing rod 516 is fixedly installed on the side of the first pressing rod 514, penetrating the first groove 517. A second connecting block 518 is fixedly installed inside the first groove 517. The second connecting block 518 is a trapezoidal rod. Mounting seats 521 are fixedly installed on the sides of both pressing blocks 512. A servo motor 523 is fixedly installed on the side of the transverse plate 313. A threaded rod 522 is fixedly installed at the output end of the servo motor 523. The threaded rod 522 is threadedly connected to the inside of the two mounting seats 521. The internal threads of the two mounting seats 521 rotate in opposite directions.

[0026] More specifically, when the extrusion block 512 moves laterally along the slide groove 511, it drives the first extrusion rod 514 and the second extrusion rod 516 to move synchronously. As the second extrusion rod 516 moves with the extrusion block 512, it contacts and extrudes the trapezoidal inclined surface of the second connecting block 518. Through the inclined surface transmission, it drives the second connecting block 518 and the third extrusion rod 415 to move outward together, releasing the clamping and fixing of the seedling by the third extrusion rod 415. When the second extrusion rod 516 continues to move with the extrusion block 512 and passes the top of the second connecting block 518, the third extrusion rod 415 loses its grip. The outer thrust returns to the initial position under the rebound force of the elastic structure, re-clamping and fixing the seedlings. After the servo motor 523 is started, the output shaft of the servo motor 523 drives the threaded rod 522 to rotate synchronously. Since the internal threads of the two mounting seats 521 rotate in opposite directions, the rotation of the threaded rod 522 will drive the two mounting seats 521 to move in opposite or opposite directions in a straight line along the threaded rod 522. By controlling the rotation direction of the threaded rod 522, the relative movement direction and movement distance of the two extrusion blocks 512 can be precisely controlled, so as to realize the gathering and resetting adjustment of the seedlings.

[0027] like Figure 3 As shown, specifically, the extrusion structure includes a discharge rack 311 fixedly installed on the upper side of the sliding plate 315. One end of an extrusion column 332 is fixedly installed on the upper side of the discharge rack 311, extending to the side of the second support plate 326. A connecting rod 416 is fixedly installed on the side of the extrusion column 332. A pushing rod 417 is fixedly installed on one end of the connecting rod 416. One end of the pushing rod 417 extends to the inner side of the third extrusion rod 415. The elastic structure includes a fixing block 411 fixedly installed on the side of the transverse plate 313. A sliding column 412 is slidably installed inside the fixing block 411. The third extrusion rod 415 is fixedly installed on one end of the sliding column 412. A protrusion 413 is fixedly installed on the other end of the sliding column 412. A first spring 414 is fixedly installed on the end face of the protrusion 413. The other end of the first spring 414 is fixedly installed on the side of the fixing block 411.

[0028] More specifically, when the sliding plate 315 slides up and down, it drives the first connecting block 331 to move synchronously. The first connecting block 331 further drives the squeezing column 332 to move up and down together with the sliding plate 315. During the downward movement of the squeezing column 332, its end contacts and squeezes the second support plate 326, driving the second support plate 326 to rotate downward around the rotating shaft 324, opening the seedling downward passage. At the same time as the squeezing column 332 moves, it drives the side connecting rod 416 to move synchronously. The connecting rod 416 further drives the pusher... As the extrusion rod 417 moves downward, its end inserts into the inner side of the third extrusion rod 415 and applies a pushing force to it, driving the third extrusion rod 415 to move away from the transverse plate 313, thus completing the repositioning action. The third extrusion rod 415 is always under the tension of the first spring 414. When the pushing rod 417 removes the pushing force upward, the first spring 414 pulls the third extrusion rod 415 back to the inner side through the protrusion 413 and the sliding column 412, thereby realizing the automatic clamping and fixing of the seedlings.

[0029] Working principle: In the initial state, the telescopic conveyor 613 is in a retracted state. The connecting plate 612 drives the sliding plate 315 to remain above the work frame 314. In the limiting structure, the torsion spring 325 is in its natural state. The rotating shaft 324 drives the second support plate 326 to maintain a horizontal supporting state. Together with the baffle 321 on the side of the work frame 314 and the side plate 318 on the transverse plate 313, they form a temporary seedling storage space. A batch of rice seedlings and a quantitatively proportioned enzyme microbial fertilizer are placed in this temporary storage space. The bottom of the seedlings is supported by the second support plate 326, and the sides are constrained by the baffle 321 and the side plate 318, stably remaining at the seedling storage position, awaiting delivery. When the transplanting position needs additional seedlings, the telescopic conveyor 613 extends, pushing the connecting plate 612... The sliding plate 315 slides downward along the transverse plate 313. During the downward movement of the sliding plate 315, the extrusion structure on it moves downward synchronously. The extrusion column 332 first contacts the free end of the second support plate 326. As the sliding plate 315 continues to move downward, the extrusion column 332 pushes the second support plate 326 to rotate downward around the rotation axis 324. The torsion spring 325 is twisted and stores force. When the second support plate 326 rotates to be parallel to the side of the sliding plate 315, the feeding channel is fully opened. A certain amount of seedlings and microbial fertilizer in the temporary storage space moves downward together with the sliding plate 315. At the same time, the extrusion column 332 drives the pushing rod 417 to move downward synchronously through the connecting rod 416 on the side. The end of the pushing rod 417 is inserted into the inside of the third extrusion rod 415, pushing the third extrusion rod 415 to move away from the seedlings.The third extrusion rod 415 drives the sliding column 412 to slide outward along the fixed block 411. The protrusion 413 stretches the first spring 414 to store force, causing the third extrusion rod 415 to exit the downward path of the seedlings, eliminating spatial interference. When the sliding plate 315 carrying the seedlings completely passes the second support plate 326, the second support plate 326 loses the extrusion force and automatically rotates back to the horizontal state under the elastic force of the torsion spring 325, supporting the remaining seedlings above again, completing the single quantitative feeding and ensuring that the number of seedlings falling each time is consistent. After the sliding plate 315 carrying the seedlings descends to the corresponding position of the drag plate 316, the telescopic mechanism 613 begins to retract, driving the sliding plate 315 to slide upward and reset. During the upward movement of the sliding plate 315, the extrusion structure moves upward synchronously, and the push rod 417 gradually exits the inner side of the third extrusion rod 415. The third extrusion rod 415 loses the outward pushing force. Under the tension of the first spring 414, the sliding column 412 carries the seedlings to the horizontal position. The third squeezing rod 415 moves towards the seedlings, squeezing and clamping the seedlings from both sides, and stabilizing them on the tray 316 at the position corresponding to the transplanting trough 317, thus completing the precise positioning of the seedlings and preparing for the transplanting action. The operator holds the handle 114 and pushes the device forward along the paddy field. The rolling wheel 211 contacts the field surface and rotates synchronously with the device. When the rolling wheel 211 rotates, it drives the first toothed disc 212, which is fixed coaxially at its center, to rotate synchronously. The first toothed disc 212 transmits power to the second toothed disc 213 through the chain 214, causing the second toothed disc 213 to rotate synchronously. The second toothed disc 213 is fixed coaxially with the rotation center of the rotating connecting rod 215. Therefore, the second toothed disc 213 drives the rotating connecting rod 215 to make a rotary motion. The plug 216 at the end of the rotating connecting rod 215 makes a circular trajectory motion with the rotary motion. When the plug 216 moves to the upper front position, it aligns with the transplanting trough 317 on the tray 316.As the connecting rod 215 continues to rotate, the plug 216 passes through the transplanting groove 317, inserting the clamped and positioned seedlings along with the microbial fertilizer into the paddy field soil to complete the fixed-depth transplanting. After transplanting, the plug 216 rotates upwards and exits the soil, entering the next transplanting cycle. During the operation, the transverse plate 313 reciprocates along the first support plate 312, driving the four groups of seedlings on the slide plate 316 to align with the working position of the plug 216 in sequence, realizing continuous cyclic transplanting of the four transplanting grooves 317 and ensuring the continuity of the operation. As the transplanting operation continues, the seedlings on both sides of the slide plate 316 are gradually consumed, and the seedlings become sparse. At this time, it is necessary to gather the remaining seedlings to the corresponding positions of the two middle transplanting grooves 317 to ensure the normal operation of subsequent transplanting operations. The servo motor 523 starts, driving the threaded rod 522 at the output end to rotate. Since the internal threads of the two mounting seats 521 rotate in opposite directions, when the threaded rod 522 rotates, it will drive the two mounting seats 521 to rotate along the threaded rod 522 towards the center. The relative movement of the center causes the two extrusion blocks 512 to slide towards the center along the slide groove 511. As the extrusion blocks 512 move towards the center, they cause the first extrusion rod 514 and the second extrusion rod 516 inside them to move synchronously. The second extrusion rod 516 first contacts the trapezoidal inclined surface of the second connecting block 518. As the extrusion blocks 512 continue to move, the second extrusion rod 516 pushes the second connecting block 518 and the third extrusion rod 415 outward through the inclined surface, releasing the clamping and fixing of the seedlings by the third extrusion rod 415. The extrusion blocks 512 continue to move towards the center, directly pushing the seedlings together towards the middle position. When the second extrusion rod 516 passes the top of the second connecting block 518, the third extrusion rod 415 loses its outward pushing force and automatically resets under the tension of the first spring 414, re-clamping and fixing the gathered seedlings from both sides. At this point, the seedlings are concentrated at the corresponding positions of the two middle transplanting slots 317, and the device can continue transplanting operations through the middle station. No manual handling is required throughout the process, ensuring high operational efficiency.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
