Description

Technical Field

[0001] This invention relates to the field of crop planting technology, and in particular to an auxiliary planting device for seedling planting. Background Technology

[0002] In agricultural production, seedling transplanting is a crucial step in the planting of vegetables, grains, and economic forests, widely used in greenhouse seedling cultivation followed by field planting, large-scale planting of economic forests in mountainous areas, and year-round production of greenhouse vegetables. With the development of large-scale and intensive agriculture, traditional manual transplanting methods, due to their high labor intensity, low efficiency, and unstable planting quality (such as uneven plant spacing and inconsistent planting depth), can no longer meet the precision and efficiency requirements of modern agricultural production. Therefore, various auxiliary planting devices for seedling cultivation have emerged, becoming core equipment for reducing labor costs and improving the standardization of transplanting operations.

[0003] Currently, mainstream seedling-assisted planting devices are mainly divided into two categories: semi-mechanized and mechanized. Their basic workflow usually includes four major steps: feeding, trenching, planting, and covering with soil. Semi-mechanized devices (such as manual seedling guide tube transplanters) require manual placement of seedlings into the guide tube, which guides the seedlings to fall into the pre-dug trench by gravity. Some devices are equipped with simple clamping structures to prevent the seedlings from tilting. Mechanized devices (such as chain clamp transplanters) automatically feed seedlings via a conveyor belt, and the chain clamping mechanism holds the seedlings as they move with the chain to the planting position. After releasing the seedlings, the covering with soil mechanism completes the planting.

[0004] However, existing devices still suffer from insufficient precision in seedling delivery in practical applications. Most devices rely on the seedlings' own gravity or simple guiding structures to achieve delivery, lacking precise control over the seedlings' falling trajectory. This can easily lead to seedlings shifting or tilting due to factors such as the inertia of the clamping mechanism when it is released or uneven soil surfaces, affecting the uniformity of subsequent growth.

[0005] Therefore, in response to the above problems, an auxiliary planting device for seedling cultivation is proposed to solve these problems. Summary of the Invention

[0006] To overcome the above shortcomings, the present invention provides an auxiliary planting device for seedling planting, which aims to improve the problem that the existing auxiliary planting devices have insufficient accuracy in seedling placement, which affects the consistency of subsequent seedling growth.

Two magnetic rods with opposite magnetic properties are fixedly connected to the outside of each rotating post. Multiple barrier plates are slidably connected inside the seedling receiving tray. As a further description of the above technical solution: The shape of the barrier plate is adapted to the shape of the tail end of the feeding block, and the barrier plate is used to isolate the magnetic force between the tail end of the feeding block and the magnetic rod. As a further description of the above technical solution: The seedling tray includes a fixed tray, the outer side of which is fixedly connected to the inner side of a fixed cylinder. The inside of the fixed tray is provided with multiple sliding grooves 1 and 2. A push-out spring is provided inside the sliding groove 1, and the top of the push-out spring is connected to the bottom of the support plate.

The bottom of the L-shaped connecting rod is fixedly connected to the top of the inner ring, and the bottom of the fixed post is fixedly connected to the top of the outer ring. A force transmission rod is rotatably connected to the inner side of the fixed post, and a torsion spring is provided between the outer side of the force transmission rod and the inner side of the fixed rod. A contraction ring is hinged to the outer end of the force transmission rod, and a telescopic hinge plate is fixedly connected to the other end of the force transmission rod. The telescopic hinge plate is hinged to the top of the L-shaped connecting rod. As a further description of the above technical solution: The deceleration component includes a sliding ring, the outer side of which is slidably connected to the inner side of the fixed cylinder and the outer side of the outer ring is fixedly connected to the inner side of the sliding ring.

[0008] The present invention has the following beneficial effects: 1. In this invention, the trigger plate contacts the feeding block, which in turn switches the feeding block, rotating stake, and magnetic rod. Magnetic adsorption guides the seedlings to accurately fall into the planting pit. After feeding, the rotating stake's torsion spring, ejection spring, and hydraulic oil return to automatically reset the trigger and clamping components. This ensures accurate seedling feeding while enabling continuous cyclical operation, improving planting precision and overall efficiency.

[0009] 2. In this invention, the inner ring of the triggering element slides down under the weight of the seedling, driving the L-shaped connecting rod and force transmission rod of the clamping element to move, causing the contraction ring to clamp the seedling; simultaneously, the inner ring, in conjunction with the sliding ring and piston of the deceleration element, squeezes the hydraulic fluid, using hydraulic damping to allow the seedling to descend slowly. The contraction ring prevents the seedling from tilting or shifting, and the hydraulic damping reduces impact damage, effectively improving the integrity and survival rate of the seedling planting.

[0012] 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.

[0013] Reference Figures 1 to 8This invention provides an embodiment of an auxiliary planting device for seedling planting, comprising a planting cart 1. The planting cart 1 serves as the carrier of the device, providing an installation foundation and mobile support for the feeding mechanism 3, planting mechanism 4, etc., ensuring the coordinated operation of each mechanism. A control box 2 is installed on the top of the planting cart 1. The control box 2 coordinates the working status of each mechanism within the device and controls the operation of the planting cart 1, the feeding mechanism 3, and the planting mechanism 4. The feeding mechanism 3 is installed on the top of the planting cart 1, undertaking the task of receiving and transporting the seedlings to be planted, so that the seedlings can be accurately placed into the planting mechanism 4. A soil turning bucket 5 is installed at the front end of the planting cart 1. The soil turning bucket 5 operates at the front end of the planting cart 1, turning over soil pits suitable for seedling planting in advance, providing planting positions for seedlings. Multiple planting mechanisms 4 are installed inside the planting cart 1. The planting mechanism 4 serves as the core part for precise seedling planting, integrating functions such as triggering, clamping, slowing, and seedling release, completing the entire process from receiving to placing the seedlings.

[0014] The feeding mechanism 3 includes a feeding hopper 301 located inside the front end of the planting vehicle 1. The feeding hopper 301 receives the seedlings to be planted and provides initial space for seedling transport. The planting vehicle 1 is equipped with a conveyor belt 302. The conveyor belt 302, in conjunction with a motor 304 and a lever 305, transports the seedlings in the feeding hopper 301 backward, realizing continuous feeding and transport of seedlings. Multiple guide plates 303 are provided on both sides of the conveyor belt 302, facing the top opening of the fixed cylinder 41. The guide plates 303 guide the seedlings one by one. The seedlings are guided to the position directly opposite the top opening of the fixed cylinder 41 to ensure that they fall accurately into the trigger area 42 inside the fixed cylinder 41. The top of the planting vehicle 1 is equipped with a motor 304, which provides power for the feeding process and drives the lever 305 at the output end to rotate, assisting the conveyor belt 302 in transporting the seedlings. The output end of the motor 304 is fixedly connected to two levers 305. The levers 305 rotate under the drive of the motor 304, and together with the conveyor belt 302, they push the seedlings backward, assisting in the feeding and transmission of the seedlings.

[0015] The planting mechanism 4 includes a fixed cylinder 41 fixedly connected inside the planting vehicle 1. The fixed cylinder 41 serves as an external support for the planting mechanism 4, providing installation space and positioning foundation for internal components such as the seedling receiving tray 45, trigger element 42, clamping element 43, and deceleration element 44. The seedling receiving tray 45 is fixedly connected inside the fixed cylinder 41. The seedling receiving tray 45 receives seedlings falling from the top of the fixed cylinder 41 and provides a platform for the movement of the seedling placement element 46, coordinating the movement of various components during the seedling placement process. The seedling placement element 46 is installed inside the seedling receiving tray 45. To achieve precise seedling placement, the timing and position of the seedling falling into the pit are controlled by the linkage of various components. The planting mechanism 4 also includes a trigger 42, a clamping component 43, and a deceleration component 44. The trigger 42 is triggered by the weight of the seedling and initiates subsequent clamping and deceleration actions. It is the initial trigger part of the linkage of various mechanisms. The clamping component 43 clamps and fixes the falling seedling to prevent it from tilting and ensures the correct planting posture. The deceleration component 44 uses hydraulic damping to buffer the falling speed of the seedling, ensuring that the seedling falls smoothly and reducing impact damage.

[0016] The seedling release component 46 includes multiple release blocks 461 slidably connected inside the seedling receiving tray 45. Each release block 461 carries a seedling and slides under the action of a linkage structure to release and place the seedlings. A magnetic block is provided at the tail end of each release block 461, and this magnetic block cooperates with a magnetic rod 468 on the rotating post 466. Through magnetic attraction or repulsion, the release block 461 slides, precisely controlling the seedling placement. Support plates 462 are fixedly connected to both sides of each release block 461. The feeding block 461 is connected to the telescopic connecting rod 465 to transmit motion and slides within the slide groove 452. It works in conjunction with the ejector spring 463 to reset the feeding block 461. The end of the support plate 462 is hinged to the telescopic connecting rod 465, which transmits the motion of the feeding block 461 and the rotating pile 466, enabling their linkage. Multiple rotating piles 466 are rotatably connected inside the seedling tray 45. The rotating piles 466 are reset by torsion springs on both sides, driving the magnetic rod 468 to switch. This, in conjunction with the magnetic block at the tail end of the feeding block 461, controls the sliding state of the feeding block 461. Torsion springs are provided on both sides of the rotating pile 466. A drive rod 467 is fixedly connected to the outer side of the rotating pile 466. The drive rod 467 converts the rotation of the rotating pile 466 into the motion of the telescopic connecting rod 465, linking the feeding block 461. The other end of the drive rod 467 is hinged to the other end of the telescopic connecting rod 465. Two magnetic rods 468 with opposite magnetic properties are fixedly connected to the outer side of the rotating pile 466. The rod 468 cooperates with the magnetic block at the tail end of the feeding block 461. Through magnetic attraction or repulsion, the feeding block 461 is driven to slide, accurately guiding the seedlings to be placed. Multiple baffles 464 are slidably connected inside the seedling receiving tray 45. The baffles 464 control the timing of the magnetic force between the tail end of the feeding block 461 and the magnetic rod 468. The shape of the baffles 464 is adapted to the shape of the tail end of the feeding block 461 and is used to isolate the magnetic force between the tail end of the feeding block 461 and the magnetic rod 468.

[0017] The seedling receiving tray 45 includes a fixed tray 451, which serves as the main body of the tray 45 and provides an installation base for components such as the first chute 452, the second chute 453, the feeding block 461, and the barrier plate 464, integrating the movement space of each component. The outer side of the fixed tray 451 is fixedly connected to the inner side of the fixed cylinder 41. The interior of the fixed tray 451 has multiple first chute 452 and second chute 453. The first chute 452 provides a sliding track for the support plate 462, accommodating the ejector spring 463 and assisting the support plate 462 and the feeding block 464. 1. Reset: Slide 2 453 provides sliding tracks at both ends of the top of the barrier plate 464 to guide the barrier plate 464 to slide. Slide 1 452 is equipped with an ejector spring 463 inside, and the top of the ejector spring 463 is connected to the bottom of the support plate 462. The ejector spring 463 provides an upward elastic force to the support plate 462 and the feeding block 461 to help them reset after the seedlings are placed. The outer side of the support plate 462 is slidably connected to the inside of slide 1 452, and the top two ends of the barrier plate 464 are slidably connected to the inside of slide 2 453.

[0018] The trigger element 42 includes an outer ring 421 and an inner ring 422. The outer ring 421 is fixed inside the fixing cylinder 41, providing a sliding guide base for the inner ring 422, and simultaneously triggering the sliding ring 441 of the deceleration element 44. The inner ring 422 slides on the guide post 423 inside the outer ring 421, sliding down under the weight of the seedling, driving the clamping element 43 to move, and simultaneously triggering the deceleration element 44. The outer ring 421 has multiple guide posts 423 inside, which provide sliding guidance for the inner ring 422, ensuring that the inner ring 422 slides in a fixed direction. The outer return spring 424 assists the inner ring 422 to return to its original position. The outer side of the inner ring 422 is slidably connected to the guide post 423. A return spring 424 is provided on the outside of the guide post 423. The return spring 424 is sleeved on the outside of the guide post 423. When the inner ring 422 slides down, it is compressed, providing an upward return force for the inner ring 422. A trigger plate 425 is slidably connected to the bottom of the inner ring 422. The trigger plate 425 is driven by the pressure of the seedling to move the inner ring 422 and contact and link with the feeding block 461 to trigger the seedling feeding action. A magnetic block that attracts each other is provided at the front end of the trigger plate 425. The magnetic block assists in the structural stability or movement linkage of the trigger plate 425. The bottom shape of the trigger plate 425 is adapted to the top shape of the feeding block 461.

[0019] The clamping component 43 includes an L-shaped connecting rod 431 and a fixed post 435. The L-shaped connecting rod 431 slides with the inner ring 422, driving the telescopic hinge plate 432 and the force transmission rod 433. The fixed post 435 provides a rotatable connection foundation for the force transmission rod 433, supporting its movement. The bottom of the L-shaped connecting rod 431 is fixedly connected to the top of the inner ring 422, and the bottom of the fixed post 435 is fixedly connected to the top of the outer ring 421. The force transmission rod 433 is rotatably connected to the inner side of the fixed post 435. The force transmission rod 433 is driven by the telescopic hinge plate 432 to rotate around the fixed post 435, thereby causing the contraction ring 434 to clamp or release the seedling. Furthermore, a torsion spring is provided between the outer side of the force transmission rod 433 and the inner side of the fixed rod. The torsion spring provides the force transmission rod 433 with the elastic force for rotational reset. After the clamping action, it helps the force transmission rod 433 reset, causing the contraction ring 434 to loosen. The outer end of the force transmission rod 433 is hinged to the contraction ring 434. The contraction ring 434 contracts or opens with the rotation of the force transmission rod 433, realizing the clamping, fixing or releasing of the seedling. The other end of the force transmission rod 433 is fixedly connected to a telescopic hinge plate 432. The telescopic hinge plate 432 transmits the movement of the L-shaped connecting rod 431 to the force transmission rod 433, realizing the linkage between the two. The telescopic hinge plate 432 is hinged to the top end of the L-shaped connecting rod 431.

[0020] The deceleration component 44 includes a sliding ring 441, which slides with the outer ring 421, driving the telescopic column 442 and piston 443 to move and initiate the hydraulic deceleration process. The outer side of the sliding ring 441 is slidably connected to the inner side of the fixed cylinder 41, and the outer side of the outer ring 421 is fixedly connected to the inner side of the sliding ring 441. Multiple telescopic columns 442 are provided at the bottom of the sliding ring 441. The telescopic columns 442 move with the sliding ring 441, pushing the piston 443 to slide inside the buffer cylinder 444, squeezing the oil to achieve deceleration. The bottom of the telescopic column 442 is fixedly connected to the piston 443. The piston 443 is pushed by the telescopic column 442 to squeeze the oil, using oil damping to produce a deceleration effect. Multiple buffer cylinders 44 are fixedly connected to the top of the seedling tray 45. 4. The buffer cylinder 444 contains oil, providing sliding space for the piston 443. The compression and reflux of the oil facilitates slowing and resetting. The piston 443 is slidably connected to the inner side of the buffer cylinder 444. An oil tank 445 is provided on the outer side of the buffer cylinder 444. The oil tank 445 contains oil and works with the buffer cylinder 444 to facilitate the compression and reflux of the oil, assisting in slowing and resetting. The bottom of the oil tank 445 is connected to the bottom of the buffer cylinder 444. A sliding baffle 446 is provided inside the oil tank 445. The sliding baffle 446 slides within the oil tank 445 and moves with the inflow and outflow of oil. It uses its own gravity to assist the reflux of oil between the buffer cylinder 444 and the oil tank 445, assisting in the resetting of the slowing component 44 and related structures.

[0021] Working principle: First, the planting vehicle 1 starts, and the soil turning bucket 5 at the front end begins to work, turning the soil into a suitable pit for planting seedlings; at the same time, the control box 2 on the top coordinates the various mechanisms to enter the working state, and the feeding mechanism 3 starts to run.

[0022] In the feeding mechanism 3, the feeding hopper 301 receives the seedlings to be planted. The motor 304 starts and drives the two levers 305 at the output end to rotate. The levers 305 work with the conveyor belt 302 to transport the seedlings backward. The multiple guide plates 303 on both sides of the conveyor belt 302 guide the seedlings one by one to the position facing the top opening of the fixed cylinder 41 in the planting mechanism 4, so that the seedlings fall accurately into the trigger 42 area inside the fixed cylinder 41.

[0023] When the seedling falls into the trigger 42, the seedling's own weight acts on the inner ring 422, causing the inner ring 422 to slide downward along the guide post 423 inside the outer ring 421 fixed inside the fixing cylinder 41, compressing the return spring 424 outside the guide post 423; at the same time, the trigger plate 425 at the bottom of the inner ring 422 is driven by the pressure of the seedling to move the entire inner ring 422 downward. When the return spring 424 is compressed to its limit, the inner ring 422 drives the entire outer ring 421 to move downward.

[0024] As the inner ring 422 slides downward, the L-shaped connecting rod 431 fixedly connected to its top moves downward simultaneously. The telescopic hinge plate 432 hinged at the top of the L-shaped connecting rod 431 moves accordingly, causing the force transmission rod 433 to rotate inward around the fixed pile 435. This causes the contraction ring 434 hinged at the outer end of the force transmission rod 433 to contract, clamping and fixing the falling seedling to prevent it from tilting during the subsequent descent.

[0025] At the same time, the downward movement of the outer ring 421 causes the sliding ring 441, which is fixedly connected to its outer side, to slide along the inner side of the fixed cylinder 41. The telescopic column 442 at the bottom of the sliding ring 441 pushes the piston 443 to move downward inside the buffer cylinder 444. After the oil in the buffer cylinder 444 is squeezed by the piston 443, it enters the oil tank 445 through the pipe connected to the bottom of the buffer cylinder 444, pushing the sliding baffle 446 inside the oil tank 445 to move. The damping effect of the oil is used to buffer the falling speed of the seedling, ensuring that the seedling slows down and the speed is the lowest when the inner ring 422 reaches the lowest point.

[0026] When the inner ring 422 descends to its lowest point, the trigger plate 425 contacts the feeding block 461, causing the trigger plate 425 to move the inner ring 422 upwards while simultaneously separating it outwards. The upward movement of the inner ring 422 acts on the clamping member 43, causing the contraction ring 434 to open. The seedling is released from the clamping state and falls. Furthermore, due to the weight of the seedling and the compression of the trigger plate 425, the four feeding blocks 461 move downwards a certain distance via the support plate 462, thereby causing the magnet at the tail end of the feeding block 461 to... The block and the barrier plate 464 are misaligned. At the same time, the falling of the feeding block 461 drives the drive rod 467 to rotate inward through the telescopic connecting rod 465, which in turn drives the rotating pile 466 to rotate, causing the magnetic rod 468 to switch. The magnetic rod 468 that is magnetically repelled by the magnetic block is put into the bottom of the fixed plate 451, while the magnetic rod 468 that is magnetically attracted to the magnetic block pops out. The attraction force of the magnetic rod 468 drives the entire feeding block 461 to slide outward, so that the seedling falls accurately into the pit.

[0027] After the seedlings are released, the rotating pile 466 rotates in the opposite direction under the force of the torsion spring, causing the material release block 461 to reset. At the same time, after the material release block 461 retracts to the center to its limit, it is pushed upward by the ejector spring 463, so that the tail end of the material release block 461 is re-locked into the inner side of the barrier plate 464. During the process, the repulsive magnetic rod 468 gradually pops out, making the material release block 461 close more smoothly. When the material release block 461 is pushed upward, the hydraulic oil enters the buffer cylinder 444 due to the gravity of the sliding partition plate 446 and the hydraulic oil inside the oil tank 445. The trigger 42 and the clamping member 43 are reset by the built-in spring of the telescopic column 442.

[0028] Subsequently, the feeding mechanism 3 continuously delivers the next batch of seedlings, and the various components of the planting mechanism 4 are reset under the action of the reset spring 424, torsion spring, ejection spring 463, etc., and enter the cycle of planting the next seedling, thus realizing continuous seedling assisted planting operation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
