Description

Technical Field

[0001] This invention relates to the field of agricultural implements technology, specifically to a rapid rice transplanting device for rice seedling cultivation. Background Technology

[0002] Mechanized rice transplanting is a core component of large-scale rice production, significantly replacing manual transplanting, reducing labor intensity in the fields, shortening the transplanting cycle, and alleviating the production contradiction of tight crop rotation in double-cropping rice areas. Currently, mainstream transplanting equipment is divided into hand-held small rice transplanters and high-speed riding rice transplanters, suitable for various types of paddy fields in plains and low hills. Conventional models rely on seedling trays and seedling claws to complete the seedling picking and transplanting processes. However, commonly used models on the market generally have shortcomings such as poor material feeding zones, uncontrollable seedling picking force, and no soil compaction structure after transplanting. When operating in large-scale contiguous paddy fields, traditional models have limited single seedling storage capacity, and the seedling conveying and transplanting actions are not synchronized, which can easily lead to missed transplanting, root damage, and seedling lodging, directly affecting the seedling recovery speed and subsequent yield per acre. Therefore, the industry urgently needs rapid transplanting equipment that integrates automatic material feeding, simultaneous seedling picking, and post-transplanting soil covering and compaction.

[0003] In the prior art, such as the high-speed rice transplanter that is easy to move in various terrains according to application number 202510418025.1, the technical solution is as follows: The invention includes a support frame, a transplanting action plate, and a moving system; the transplanting action plate is equipped with a seedling tray and a moving plate, and the seedlings are automatically separated and transplanted through the seedling separation baffle and the transplanting fork; the transplanting fork is guided by a circular track, and the drive motor ensures accurate movement; the equipment adopts a dual moving structure of motor wheels and tracks, and adapts to different terrains through hydraulic cylinders; the seedling pushing permanent magnet block and bipolar electromagnet solve the problem of seedling adhesion and ensure the continuity of operation.

[0004] In actual paddy field operations, the seedling feeding only uses a fixed flat plate structure without a reciprocating horizontal distribution component. The seedlings are piled up in a concentrated manner, and the number of seedlings picked up by the seedling picking claws is uneven in a single operation, which easily leads to multiple seedlings and missed planting in empty holes. In addition, the walking wheel drive and the transplanting mechanism are independent of each other, requiring additional power to drive the two mechanisms separately. The overall structure of the machine is cumbersome, the failure rate is relatively high, and the overall transplanting stability and operation efficiency have obvious shortcomings.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was developed based on the existing rice transplanting device. Summary of the Invention

[0007] The purpose of this invention is to provide a rapid rice transplanting device for rice seedling cultivation, so as to solve the problems of poor transplanting stability and low operating efficiency mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A rapid rice transplanting device for rice seedling cultivation includes a support base. A push rod is fixedly installed on the front side of the support base. Wheels are rotatably connected to both sides of the support base, and a rotating rod is connected between the wheels. The rotating rod is rotatably connected to the upper surface of the support base. A carrying box is fixedly connected to the rear side of the upper surface of the support base, and a support frame is fixedly installed at the rear end of the support base. An inclined frame is fixedly connected to the rear end of the carrying box, and a feeding tray is provided inside the inclined frame. A reciprocating screw is connected inside the inclined frame, and the front end of the feeding tray is connected to the reciprocating screw to form a left-right reciprocating movement structure. Two first gears are fixedly connected in the middle of the rotating rod, and a second gear is rotatably connected between the support frames. Chains are sleeved on the outer sides of the first and second gears. Gearboxes are fixedly connected to the left and right rotating shafts of the second gear, and two transplanting arm assemblies are connected to the outer ends of the gearboxes. A gripping rod is connected to the side of the transplanting arm assembly closest to the feeding tray.

[0009] Preferably, a triangular bracket is fixedly installed at the front end of the support base, and a traction hook is fixedly installed at the front end of the triangular bracket, and a support wheel is connected to the bottom of the triangular bracket.

[0010] Using the above technical solution, the towing hook can be directly connected to agricultural towing machinery such as tractors, making it suitable for mechanized towing operations in large-area paddy fields. The support wheel bears the front load when the equipment is stationary or being transported, preventing the whole machine from tilting forward and overturning. The triangular bracket has a stable triangular mechanical structure with high load-bearing strength, making it less prone to deformation and bending on muddy paddy fields. It supports both manual operation by a single person pushing the lever and external towing by agricultural machinery. One machine is suitable for both manual operation in small plots and mechanical operation in large fields, greatly expanding the scope of application of the equipment and significantly improving the stability of transportation and parking.

[0011] Preferably, the top of the carrier box is used to place rice seedlings to be transplanted.

[0012] Using the above technical solution, a carrying box is set on the rear side of the support base. The top of the box is open for stacking rice seedling trays. The large-capacity box can load multiple trays of seedlings at one time, reducing the frequency of repeated seedling replenishment and machine stoppage for feeding in the field, and significantly increasing the continuous operation time.

[0013] Preferably, the left and right ends of the rotating rod are connected to a transmission belt, and the rear end of the transmission belt is connected to the left and right ends of the reciprocating lead screw. Two sliding rods are fixedly connected inside the inclined frame, and the sliding rods are arranged parallel to the upper and lower sides of the reciprocating lead screw.

[0014] Using the above technical solution, the forward traveling wheel drives the rotating rod to rotate synchronously. The screw can be driven by the belt without an additional motor, realizing synchronous linkage between walking and feeding. The double slide rods form double-sided guide support for the feeding plate, limiting the slider's deviation and swaying. The reciprocating movement is smooth and without jamming. The pure mechanical linkage eliminates the need for an independent drive motor, simplifies the overall circuit structure, reduces the failure rate in humid paddy field environments, and automatically feeds materials by relying on the traveling power. It is energy-saving, environmentally friendly, and easy to operate and maintain.

[0015] Preferably, a first slider is fixedly welded to the middle of the front side of the feeding tray, and a second slider is arranged parallel to the upper and lower positions of the first slider. The first slider is connected to the reciprocating lead screw, and the second slider is slidably connected to the slide rod.

[0016] Using the above technical solution, a combination of one main and two auxiliary sliders forms a three-point limiting support. The feeding disc maintains a horizontal posture throughout its left and right reciprocating motion, preventing seedlings from slipping due to unilateral tilting. The screw drive provides precise reciprocating stroke, and the two sliders share the weight of the seedlings, avoiding wear and deformation of the slider on one side. The synchronous linkage walking speed adjusts the feeding frequency. The faster the movement, the faster the feeding and switching, resulting in uniform feeding, reducing the problems of empty holes and multiple seedlings, improving the uniformity of transplanting, and extending the service life of slider and screw components.

[0017] Preferably, the rear side of the feeding tray is provided with partitions at equal intervals, and the bottom of the feeding tray is provided with a stop bar.

[0018] Using the above technical solution, the partition separates the seedling raising area into equal-width feeding zones, preventing seedlings from piling up and tangling together. This ensures that the gripping rod can grab a fixed amount of seedlings at a time, while the bottom baffle limits the slippage of the seedling tray and controls the height of the seedlings as they fall, preventing damage to the root system from falling from a height. The compartmentalized feeding structure enables orderly feeding, and the amount of seedlings grabbed is stable and controllable. This reduces defects such as missed planting and multiple seedlings being planted from the source, improves the survival rate of seedlings, and reduces the labor cost of replanting seedlings later.

[0019] Preferably, the center of the gearbox is fixedly connected to the left and right rotating shafts of the second gear, and a drive gear is provided in the middle of the gearbox, and the drive gear is fixedly connected to the ends of the left and right rotating shafts of the second gear.

[0020] With the above technical solution, when the chain drives the second gear to rotate, the drive gear outputs power synchronously, serving as the power input end of the transplanting mechanism. The power transmission is coaxial and lossless. The sealed housing of the gearbox isolates the paddy field mud and silt, protecting the internal gears from corrosion and jamming. It is suitable for the harsh working conditions of muddy paddy fields. The integrated coaxial structure simplifies the transmission path, and the power response is highly synchronized. The three mechanisms of walking, feeding, and transplanting are completely synchronized and linked, with high motion matching degree, and the overall stability of the machine's collaborative operation is greatly enhanced.

[0021] Preferably, both sides of the driving gear are meshed with driven gears, and the driven gears are rotatably connected inside the gearbox. The outer ends of the driven gears are connected to the rice transplanter arm assembly via rotating shafts.

[0022] Using the above technical solution, a single input power is used to drive the two transplanting arms, enabling simultaneous transplanting of rice seedlings in both rows. This doubles the working width and significantly improves efficiency. The gear meshing transmission has a large torque, ensuring powerful operation even under the resistance of paddy field silt, preventing issues such as weak seedling clamping or incomplete transplanting. The sealed gearbox protects against mud and water erosion, and the gears wear slowly, allowing for long-term continuous operation without frequent maintenance. This solution is suitable for large-scale, contiguous paddy field uninterrupted rice transplanting operations.

[0023] Preferably, a connecting rod is hinged between the two rice transplanting arm assemblies on the outside of the gearbox, and a gripping opening is provided at the bottom of the gripping rod below the rice transplanting arm assembly, and a limit plate is fixedly installed inside the rear side of the gripping rod.

[0024] Using the above technical solution, the connecting rod constrains the swing amplitude of the left and right transplanting arms, ensuring that the gripping arms on both sides rise and fall synchronously to pick up seedlings, the gripping position is uniform, the size of the gripping opening is adapted to the standard seedling cluster, the limiting plate limits the maximum stroke of the clamping, and avoids excessive clamping force squeezing and breaking the seedling roots and stems. The mechanical limiting precisely controls the clamping force, taking into account both firm gripping and seedling protection, effectively reducing the seedling damage rate and improving the quality of the transplanted rice.

[0025] Preferably, a positioning pressure plate is provided on the lower rear side of the gripping rod, and the positioning pressure plate is used to position and press the soil above the seedling hole. A limiting rod is fixedly connected to the upper surface of the positioning pressure plate, and a sliding plate is fixedly connected above the limiting rod. The sliding plate is slidably connected in the groove on the rear side of the gripping rod, and the limiting rod is slidably connected to the limiting plate. A spring is connected between the limiting plate and the sliding plate.

[0026] Using the above technical solution, when transplanting rice seedlings, the positioning plate first contacts the soil, and the spring buffers the clamping force, automatically compacting the mud around the roots of the seedlings to prevent the paddy field water from washing away the newly transplanted seedlings. The plate rises and falls synchronously with the gripping rod, and transplanting and soil compaction are completed in one step, eliminating the need for subsequent manual tamping of the seedlings. The spring adapts to the softness and hardness of the paddy field mud layer, ensuring that the seedlings are not broken in hard soil and that soft soil is fully compacted, greatly reducing the lodging rate of seedlings and improving the survival rate after greening up.

[0027] Compared with the prior art, the beneficial effects of the present invention are: this rapid rice transplanting device for rice seedling cultivation... 1. Equipped with a walking wheel linkage drive for a reciprocating horizontal feeding tray, this device relies on the walking wheel to drive the rotating rod, which in turn drives the reciprocating screw in the inclined frame via a transmission belt. The screw drives the feeding tray to move back and forth. No additional power such as motors or hydraulics is required throughout the process. Automatic material distribution is achieved entirely by the mechanical energy of the equipment's forward movement. The feeding tray has built-in uniform partitions for storing seedlings, and the bottom baffle stabilizes and limits the seedlings. The upper and lower double sliding rods, along with the double-layer slider, support the feeding tray, ensuring smooth reciprocating movement without tilting. The equipment's forward speed directly matches the feeding switching frequency. The faster the equipment moves, the faster the feeding switching, achieving complete synchronization between movement and feeding. This eliminates problems such as seedling accumulation, uneven seedling collection, and missed planting in empty holes that are common with traditional fixed feeding trays. 2. The entire rice transplanting mechanism is equipped with a walking wheel chain linkage, allowing multiple mechanisms to work synchronously and collaboratively. The first gear on the walking wheel rotating rod is linked to the second gear through the chain. The power is distributed to the driven gears on both sides through the coaxial driving gear, synchronously driving the two sets of transplanting arm assemblies. This achieves synchronous linkage of the three mechanisms of walking, distributing, and transplanting. The whole machine relies on a single power source of the walking wheel, eliminating multiple independent drive components, simplifying the structure and reducing manufacturing costs. At the same time, it avoids the defects of seedling misalignment and uneven seedling depth caused by asynchronous operation of multiple motors. The sealed gearbox isolates mud and silt, and the internal gears are not easy to rust and jam. The connecting rod constrains the synchronous swing of the transplanting arms on both sides, ensuring that the transplanting depth and seedling quantity of the left and right rows are completely consistent. 3. A spring-loaded, buffered positioning plate assists in soil positioning, effectively preventing seedling lodging. An elastic positioning plate is added below the transplanting arm's gripper. This plate, along with a limiting rod, sliding plate, and buffer spring, forms an adaptive compaction structure. When the gripper lowers to plant the seedling, the plate first contacts the paddy field soil. The spring buffers the downward impact, automatically compacting the mud around the seedling roots to form a stable planting hole. This prevents flowing water from washing over the seedlings. The spring automatically adjusts the compaction force according to the mud's hardness; in hard mud, it buffers and protects the roots from being broken, while in soft mud, it fully compacts to prevent seedlings from floating. Transplanting and soil compaction are completed simultaneously in one step, eliminating the need for workers to step on and secure the seedlings, significantly reducing field labor, effectively lowering the probability of lodging and floating seedlings, increasing seedling survival rate, and ensuring stable rice yield per acre later on.

[0030] 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.

[0031] Please see Figure 1-10 The present invention provides a technical solution: A rapid rice transplanting device for rice seedling cultivation includes a support base 1. A push rod 2 is fixedly installed on the front side of the support base 1. Wheels 4 are rotatably connected to both sides of the support base 1, and a rotating rod 5 is connected between the wheels 4. The rotating rod 5 is rotatably connected to the upper surface of the support base 1. A carrying box 101 is fixedly connected to the rear side of the upper surface of the support base 1, and a support frame 102 is fixedly installed at the rear end of the support base 1. An inclined frame 6 is fixedly connected to the rear end of the carrying box 101, and a feeding tray 7 is provided inside the inclined frame 6. There is a reciprocating screw 601, and the front end of the feeding plate 7 is connected to the reciprocating screw 601 to form a left and right reciprocating movement structure. Two first gears 9 are fixedly connected in the middle of the rotating rod 5, and a second gear 10 is rotatably connected between the support frame 102. A chain 11 is sleeved on the outside of the first gear 9 and the second gear 10. Gearboxes 12 are fixedly connected to the left and right rotating shafts of the second gear 10. Two rice transplanter arm assemblies 13 are connected to the outer ends of the gearboxes 12. A gripping rod 15 is connected to the side of the rice transplanter arm assembly 13 near the feeding plate 7.

[0032] A triangular bracket 3 is fixedly installed at the front end of the support base 1, and a traction hook 301 is fixedly installed at the front end of the triangular bracket 3. A support wheel 302 is connected to the bottom of the triangular bracket 3. The top of the carrying box 101 is used to place rice seedlings to be transplanted. The traction hook 301 can be directly connected to agricultural traction machinery such as tractors, which is suitable for mechanized traction operations in large-area rice fields. The support wheel 302 bears the front load when the equipment is stationary or being transported, preventing the whole machine from tilting forward and overturning. The triangular bracket 3 has a triangular stable mechanical structure with high load-bearing strength. It is not easy to deform or bend on muddy paddy fields. It supports manual operation by a single person pushing the lever 2, and can also be connected to external agricultural machinery for traction. One machine is suitable for both manual operation in small plots and mechanical operation in large fields. The scope of application of the equipment is greatly expanded, and the stability of transportation and parking is significantly improved. A carrying box 101 is set on the rear side of the support base 1. The top of the box is open for stacking rice seedling trays. The large-capacity box can load multiple trays of seedlings at one time, reducing the frequency of repeated seedling replenishment and stopping to add materials in the field, and significantly increasing the continuous operation time.

[0033] The rotating rod 5 is connected to the left and right ends of the drive belt 8, and the rear end of the drive belt 8 is connected to the left and right ends of the reciprocating screw 601. Two sliding rods 602 are fixedly connected inside the inclined frame 6, and the sliding rods 602 are arranged parallel to the upper and lower sides of the reciprocating screw 601. A first slider 703 is fixedly welded to the middle of the front side of the feeding plate 7, and a second slider 704 is arranged parallel to the upper and lower positions of the first slider 703. The first slider 703 is connected to the reciprocating screw 601, and the second slider 704 is slidably connected to the sliding rod 602. Partitions 701 are evenly spaced at the middle of the rear side of the feeding plate 7, and a stop bar 702 is provided at the bottom of the feeding plate 7. The forward traveling wheel 4 drives the rotating rod 5 to rotate synchronously. The screw can be driven by the belt without an additional motor, achieving synchronous linkage between travel and feeding. The double sliding rods 602 form double-sided guide support for the feeding plate 7, limiting slider offset and swaying. The reciprocating movement is smooth and without jamming. Pure mechanical linkage eliminates the need for an independent drive motor, simplifying the overall circuit structure. The failure rate is reduced in wet environments. Automatic material distribution relies on the vehicle's propulsion, making it energy-efficient, environmentally friendly, and easy to maintain. A main and two auxiliary slider combination forms a three-point limiting support. The feeding disc maintains a horizontal posture throughout its approximately 7-minute reciprocating motion, preventing seedling slippage due to unilateral tilt. A lead screw drive provides precise reciprocating stroke, and the double 602 sliders distribute the seedling weight, preventing unilateral wear and deformation of the slider. Synchronous linkage with the walking speed adjusts the material distribution frequency; the faster the movement, the faster the material switching, resulting in uniform feeding, reducing empty spaces and multiple seedlings, and improving transplanting uniformity. The system extends the service life of the slider and lead screw components. The partition 701 separates the seedling cultivation areas, dividing the seedlings into equal-width feeding zones to prevent them from piling up and tangling. This ensures that the gripper 15 can grab a fixed amount of seedlings at a time. The bottom baffle 702 restricts the seedling tray from slipping and controls the height of the seedlings as they fall, preventing damage to the root system from falling from a height. The compartmentalized feeding structure enables orderly feeding and a stable and controllable feeding volume. This reduces defects such as missed planting and multiple seedlings from the source, improves the seedling survival rate, and reduces the labor cost of replanting later.

[0034] The center of the gearbox 12 is fixedly connected to the left and right rotating shafts of the second gear 10. A drive gear 1201 is located inside the gearbox 12, and is fixedly connected to the ends of the left and right rotating shafts of the second gear 10. Driven gears 1202 are meshed on both sides of the drive gear 1201, and are rotatably connected inside the gearbox 12. The outer ends of the driven gears 1202 are connected to the transplanting arm assembly 13 via rotating shafts. When the chain 11 drives the second gear 10 to rotate, the drive gear 1201 synchronously outputs power, serving as the power input for the transplanting mechanism. Power transmission is coaxial and lossless. The sealed housing of the gearbox 12 isolates the paddy field from mud and silt. Protecting internal gears from rust and jamming, this machine is suitable for harsh working conditions in muddy paddy fields. Its integrated coaxial structure simplifies the transmission path, ensuring strong power response and synchronization. The three mechanisms of walking, feeding, and transplanting are fully synchronized, resulting in high motion matching and significantly enhanced stability of the entire machine. A single input power is used to drive the transplanting arms on both sides, enabling simultaneous transplanting of seedlings in both rows. This doubles the working width and significantly improves efficiency. The high torque of the gear meshing transmission ensures powerful operation even under the resistance of muddy paddy fields, preventing issues such as weak seedling clamping or incomplete transplanting. The sealed gearbox protects against mud and water erosion, slows gear wear, and allows for long-term continuous operation without frequent maintenance, making it suitable for large-scale, contiguous paddy field uninterrupted transplanting operations.

[0035] A connecting rod 14 is hinged between the two rice transplanting arm assemblies 13 on the outer side of the gearbox 12. A gripping opening 1501 is provided at the bottom of the gripping arm assembly 13's gripping rod 15, and a limiting plate 1502 is fixedly installed inside the rear side of the gripping rod 15. A positioning pressure plate 16 is provided below the rear side of the gripping rod 15, and the positioning pressure plate 16 is used to position and press the soil above the seedling hole. A limiting rod 1601 is fixedly connected to the upper surface of the positioning pressure plate 16, and a sliding plate 1602 is fixedly connected above the limiting rod 1601. The sliding plate 1602 is slidably connected in the groove on the rear side of the gripping rod 15, and the limiting rod 1601 is slidably connected to the limiting plate 1502. A spring 1603 connects the limiting plate 1502 and the sliding plate 1602. The connecting rod 14 constrains the swing amplitude of the left and right rice transplanting arms. The system ensures that the two gripping rods 15 rise and fall synchronously to pick up seedlings, with a uniform gripping position. The gripping opening 1501 is sized to fit standard seedling clusters, and the limiting plate 1502 restricts the maximum stroke of the clamping to prevent excessive clamping force from squeezing and breaking the seedling roots. The mechanical limit precisely controls the clamping force, balancing firm gripping with seedling protection, effectively reducing the seedling damage rate and improving the quality of transplanted rice. When pressing down during transplanting, the positioning pressure plate 16 contacts the soil first, and the spring 1603 buffers the clamping force, automatically compacting the mud around the seedling roots to prevent the paddy field water flow from washing away the newly transplanted seedlings. The pressure plate rises and falls synchronously with the gripping rods 15, completing transplanting and soil compaction in one step without the need for subsequent manual tamping. The spring 1603 adapts to the softness and hardness of the paddy field mud layer, ensuring that the seedlings are not broken in hard soil and are fully compacted in soft soil, significantly reducing the seedling lodging rate and improving the survival rate after greening.

[0036] Working principle: Before operation, rice seedling trays are neatly stacked inside the feeding tray 7. The seedlings slide into the bottom of the feeding tray 7, and the partition 701 separates the seedlings. The stop bar 702 prevents the seedling trays from sliding down. The equipment can be connected to a tractor via the front traction hook 301 or pushed forward manually by holding the push bar 2. When the triangular bracket 3 is parked, the bottom support wheel 302 supports the whole machine and prevents it from tilting forward. When moving in the field, the left and right walking wheels 4 rotate synchronously, driving the middle rotating rod 5 to rotate coaxially. The transmission belts 8 at both ends of the rotating rod 5 synchronously drive the reciprocating screw 601 inside the inclined frame 6 to rotate. The screw, together with the upper and lower parallel sliding rods 602, drives the feeding tray 7 to move back and forth at a uniform speed, continuously switching the seedling picking position to achieve automatic material distribution while moving, ensuring that the gripping rod 15 picks up a uniform and stable amount of seedlings. At the same time, the first tooth in the middle of the rotating rod 5 Wheel 9 rotates with the shaft, driving the second gear 10 on the support frame 102 to rotate synchronously via chain 11. The shaft of the second gear 10 is linked to the drive gear 1201 inside the gearbox 12. The drive gear 1201 meshes with the driven gears 1202 on both sides, driving the left and right sets of transplanting arm assemblies 13 respectively. The connecting rod 14 constrains the transplanting arms on both sides to swing synchronously, and the gripping rod 15 moves downward. The bottom gripping opening 1501 grabs the seedlings in the feed tray 7 and inserts them vertically into the paddy field soil. During the entire transplanting process, the lower positioning plate 16 contacts the mud surface first. The limit rod 1601 and the sliding plate 1602 compress the spring 1603 to form a buffer and press, automatically compacting the mud around the seedling roots and completing the soil covering and seedling fixation. When the transplanting arm is raised, the spring 1603 rebounds, and the pressure plate automatically resets, preparing for the next compaction action.
