Abstract
Description
Technical Field
[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a transplanting device and a vegetable transplanter. Background Technology
[0002] Seedling transplanting is widely used in vegetable cultivation because it can effectively shorten the crop growth cycle and compensate for the adverse effects of seasons and climate. However, the transplanting process faces many challenges. For a long time, manual transplanting has been the main method, which relies excessively on manpower, resulting in high labor intensity and extremely low efficiency.
[0003] To improve transplanting efficiency and reduce labor costs, the duckbill-type planter was developed. However, because the duckbill needs to be inserted into the soil frequently, it is prone to soil adhesion, causing blockage. Alternatively, the adhered soil may prevent the seedlings from falling freely into the planting hole, seriously affecting the transplanting effect and reducing the survival rate of the seedlings. Operators need to clean it frequently, which not only consumes a lot of time and energy but also greatly affects the overall work efficiency.
[0004] In addition, the existing duckbill-type planter lacks watering and fertilization functions. After transplanting, watering and / or fertilization must be carried out manually and uniformly, which is time-consuming and labor-intensive, and cannot achieve simultaneous transplanting and watering and / or fertilization, thus affecting the survival rate of transplanted seedlings. Summary of the Invention
[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a transplanting device and a vegetable transplanter to solve the problems of easy sticking and clogging when the duckbill type planter is inserted into the soil and the inability to apply water and / or fertilizer during transplanting.
[0006] To achieve the above and other related objectives, the present invention provides a transplanting device, comprising:
[0007] The frame mechanism includes two parallelogram frames arranged vertically opposite each other, and a telescopic power component for controlling the vertical extension and retraction of the lower parallelogram frame;

The fixed cylinder has one open end and the other closed end to form a rotating space. The rotating column forms a rotational seal connection with the inner wall of the rotating space. The tops of the middle sealing cap and the bottom sealing cap are rotationally and sealingly connected to the inner wall of the rotating space and the bottom of the fixed cylinder, respectively. The two annular sealing sleeves are fitted onto the rotating column, and the inner surfaces of the annular sealing sleeves are aligned with the rotating column. A static seal is formed on the outer wall of the rotating column, and a rotational seal is formed between the outer surface of the annular sealing sleeve and the inner wall of the rotating space. The outer surface of the annular sealing sleeve has two annular flow channels, and the side wall of the fixed cylinder has two inlet channels that are respectively connected to the annular flow channels. The rotating column has outlet channels that are respectively connected to the two annular flow channels in the axial direction. Sealing rings are provided between the annular sealing sleeve and the outer wall of the rotating column and the inner wall of the rotating space, and between the middle cover and the inner wall of the rotating space. The bottom of the bottom cover is coaxially and fixedly connected to the top of the seedling tube.
[0014] The power transmission module is located within the rotating space and is used to continuously supply power to the electrical components of the transplanting mechanism.
[0015] The infusion module is used to connect the receiving cavities on the two hollowing plates to the two annular flow channels respectively.
[0016] Optionally, the power transmission module includes multiple input conductive rings, multiple arc-shaped output blocks, an output disk, and an elastic element. The multiple input conductive rings are all concentrically arranged at the top of the rotation space, and the multiple arc-shaped output blocks are all concentrically arranged on the output disk. Each arc-shaped output block slides and corresponds to each input conductive ring. The output disk rotates and engages with the inner wall of the rotation space.
[0017] The elastic element is used to provide a thrust to the top side of the rotation space for the output disk;
[0018] A wire feeding channel is provided at the center of the middle cover, the rotating column, and the bottom cover.
[0019] Optionally, the infusion module has two components, and the two infusion modules are respectively connected to the two outflow channels;
[0020] Each of the infusion modules includes a first infusion tube, a spiral tube, and a second infusion tube. One end of the first infusion tube is connected to the outflow channel, and both ends of the spiral tube are connected to the other end of the first infusion tube and one end of the second infusion tube, respectively.

The air collecting chamber has a frustum-shaped through hole along its own axial direction, which is larger at the top and smaller at the bottom and coaxial with the seedling tube. The side wall of the frustum-shaped through hole has a plurality of inclined air outlet holes facing the central axis of the seedling tube and discharging air upwards in both the axial and circumferential directions. The air source communicates with the air collecting chamber and supplies air to the inclined air outlet holes.
[0024] Optionally, the tilt angle of the tilted air outlet is 30~45°.
[0025] Optionally, it also includes two soil covering mechanisms respectively located behind the transplanting mechanism;
[0026] The soil covering mechanism includes an L-shaped connecting arm and two soil covering wheels. The horizontal end of the L-shaped connecting arm is fixedly connected to the parallelogram frame above. The two soil covering wheels are symmetrically arranged on both sides of the vertical end of the L-shaped connecting arm, and the soil covering wheels are inclined at the top and bottom.
[0027] A vegetable transplanter, comprising the aforementioned transplanting device.
[0028] As described above, the transplanting device and vegetable transplanter of the present invention have at least the following beneficial effects:
[0029] The simultaneous rotation of two transplanting mechanisms via a rotary drive mechanism enables efficient and continuous transplanting operations, improving work efficiency. Simultaneous rotation ensures consistency in the actions and transplanting depth of both mechanisms, contributing to uniformity and standardization of transplanting, thereby improving overall transplanting quality and guaranteeing consistent and uniform seedling growth. The parallelogram frame design allows for staggered transplanting of seedlings between adjacent narrow rows on the ridge, optimizing planting density and spatial layout, and improving crop growth conditions and yield. The seedling discharge tube is vertically and rotatably mounted on the upper parallelogram frame, while the seedling delivery tube is vertically and rotatably mounted on the lower parallelogram frame. A circumferentially oriented limiting groove on the inner wall of the delivery tube slides into a protrusion on the bottom of the outer wall of the discharge tube. This allows the discharge tube to rotate synchronously with the delivery tube when the rotary drive mechanism rotates, and also allows for vertical movement driven by the telescopic power component. This ensures a stable and continuous transport of seedlings from the discharge tube to the delivery tube. Two symmetrically arranged digging plates, hinged below the delivery tube, fit together to form a conical structure, facilitating soil cutting and reducing soil resistance, thus improving digging efficiency. The spiral grooves on the digging plates further enhance the digging efficiency. During the planting process, the system guides the soil upwards, further reducing digging resistance and making the holes more regular. The electro-hydraulic rotating component continuously delivers electricity, water, and / or liquid fertilizer. Through communication with the receiving cavity on the digging plate, water and / or liquid fertilizer can form a liquid surface on the conical surface of the digging plate through seepage holes, isolating the soil or reducing direct contact. This achieves both anti-clogging and anti-sticking effects, and also allows for the application of root-setting water and / or liquid fertilizer during transplanting, providing a good growth environment for seedlings and improving transplanting efficiency and survival rate. This solves the problems of easy clogging, poor transplanting quality, low efficiency, and low seedling survival rate. The integrated design of digging, watering, and / or fertilizing not only improves planting efficiency and reduces operational steps, but also allows for precise watering and / or fertilization of seedlings during planting, ensuring that seedlings receive the necessary water and nutrients, promoting seedling survival and early growth.

[0044] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.
[0045] Please see Figures 1 to 10 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
[0046] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.
[0047] In this embodiment, please refer to Figures 1 to 10 This invention provides a transplanting device, comprising: a frame mechanism 1, two transplanting mechanisms 2, and a rotary drive mechanism. The frame mechanism 1 includes two parallelogram frames 11 arranged vertically opposite each other, and a telescopic power component 12 for controlling the vertical extension and retraction of the lower parallelogram frame 11. The telescopic power component 12 can be an electric push rod, a cylinder, or a hydraulic cylinder. There can be four telescopic power components 12, which are arranged between the two parallelogram frames 11. This allows for precise control of the vertical extension and retraction of the lower parallelogram frame 11, thereby flexibly adjusting the height of the transplanting mechanism 2 to adapt to the transplanting needs of seedlings at different terrains and growth stages, and improving the adaptability and accuracy of the operation.
[0048] The two transplanting mechanisms 2 are vertically and rotatably mounted on two parallel sides of the parallelogram frame 11;
[0049] Each transplanting mechanism 2 includes a seedling placement cylinder 21 vertically and rotatably mounted on the upper parallelogram frame 11, a plurality of protrusions 22 spaced circumferentially along the bottom of the outer wall of the seedling placement cylinder 21, a seed delivery cylinder 23 vertically and rotatably mounted on the lower parallelogram frame 11, two symmetrically arranged digging plates 24 respectively hinged below the seed delivery cylinder 23, a opening and closing power assembly 25 for controlling the opening and closing of the two digging plates 24, and an electro-hydraulic rotation assembly 26 for continuously supplying electricity, water and / or liquid fertilizer. The two digging plates 24 are fitted together to form a conical structure. When the conical digging plates 24 are fitted together, they form a sharp cone shape to reduce soil penetration resistance. Each digging plate 24 has a receiving cavity 27 communicating with the electro-hydraulic rotation assembly 26. Each of the digging plates 24 has a spiral groove and several leakage holes 28 on its conical surface, all of which are connected to the receiving cavity 27. The leakage holes 28 are combined with the electro-hydraulic rotating component 26, which can inject water and / or liquid fertilizer at the same time as digging, thereby improving planting efficiency and promoting seedling survival. The spiral groove facilitates soil drainage and reduces blockage. The inner wall of the seedling delivery tube 23 has multiple limiting grooves 29 that slide and cooperate with the protrusions 22. The side wall of the seedling release tube 21 has a seedling release port 210, which facilitates the release of seedlings. After the digging plate 24 has dug the hole, the seedling release port 210 always faces the direction of seedling delivery, which enables the seedlings to be accurately and quickly placed into the seedling release tube 21, and ensures the consistency and standardization of seedling release, which is conducive to improving the efficiency and quality of transplanting.
[0050] The rotary drive mechanism drives the two transplanting mechanisms 2 to rotate simultaneously, which enables efficient continuous transplanting operations, improves work efficiency, and ensures the consistency of the actions of the two transplanting mechanisms 2 by synchronous rotation, which helps to ensure the uniformity and standardization of transplanting.
[0051] The simultaneous rotation of two transplanting mechanisms 2 via a rotary drive mechanism enables efficient and continuous transplanting operations, improving work efficiency. Furthermore, the synchronous rotation ensures consistency in the actions and transplanting depth of the two mechanisms, contributing to uniformity and standardization of transplanting, thereby improving overall transplanting quality and guaranteeing the consistency and uniformity of seedling growth. The parallelogram frame 11 design allows for staggered transplanting of seedlings between adjacent narrow rows on the ridge, optimizing planting density and spatial layout, and improving crop growth conditions and yield. The seedling release tube 21 is vertically and rotatably mounted on the upper parallelogram frame 11, and the seedling delivery tube 23 is vertically and rotatably mounted on the lower parallelogram frame 11. The circumferential limiting groove 29 on the inner wall of the seedling delivery tube 23 slides into contact with the protrusion 22 on the bottom of the outer wall of the seedling release tube 21. This allows the seedling release tube 21 to drive the seedling delivery tube 23 to rotate synchronously when the rotary drive mechanism rotates, and also allows it to move up and down under the drive of the telescopic power component 12. This ensures a stable and continuous transport of seedlings from the seedling release tube 21 to the seedling delivery tube 23. Two symmetrically arranged and hinged digging plates 24 below the seedling delivery tube 23 fit together to form a conical structure, which facilitates digging holes by cutting into the soil, reducing soil resistance, and improving digging efficiency. The spiral grooves on the 24 guide the soil upwards during digging, further reducing digging resistance and making the holes more regular. The electro-hydraulic rotating component 26 continuously delivers electricity, water, and / or liquid fertilizer. Through communication with the receiving cavity 27 on the digging plate 24, water and / or liquid fertilizer can form a liquid surface on the conical surface of the digging plate 24 through the seepage holes 28, isolating the soil or reducing direct contact. This achieves both anti-sticking and anti-clogging effects, and also allows for the application of root-setting water and / or liquid fertilizer during transplanting, providing a good growth environment for seedlings and improving transplanting efficiency and survival rate. This solves the problems of easy clogging, poor transplanting quality, low efficiency, and low seedling survival rate. The integrated design of digging and watering / / or fertilizing not only improves planting efficiency and reduces operational steps, but also allows for precise watering and / or fertilization of seedlings during planting, ensuring that seedlings receive the necessary water and nutrients, promoting seedling survival and early growth.
[0052] In this embodiment, please refer to Figure 1The rotary drive mechanism includes two first gears 31, a second gear 32, a parallelogram plate 33, and a rotary power component 34 for driving the second gear 32 to rotate. The rotary power component 34 includes a motor or a hydraulic motor. The parallelogram plate 33 is fixedly connected to the parallelogram frame 11 above it. The second gear 32 is vertically and rotatably mounted on the parallelogram plate 33. The two first gears 31 are coaxially fixedly engaged with the two seedling cylinders 21, and both first gears 31 mesh with the second gear 32 for transmission. During operation, the rotating power component 34 drives the second gear 32 to rotate, which in turn drives the two meshing first gears 31 to rotate, thereby driving the two seedling cylinders 21 to rotate synchronously. This achieves the operation of two transplanting mechanisms 2 with one power source, saving costs and creating a compact structure. It also ensures the uniformity and standardization of transplanting depth, which is beneficial to improving the overall transplanting quality. The use of gear transmission can ensure the high efficiency and accuracy of power transmission. Gear transmission has high transmission efficiency and can effectively transmit the power of the rotating power component 34 to the seedling cylinders 21, thereby driving the transplanting mechanism 2 to rotate.
[0053] In this embodiment, please refer to Figure 2 The opening and closing power assembly 25 includes a telescopic drive component 251, two horizontal arms 252, two lugs 253, and an inclined connecting rod 254. The two horizontal arms 252 are respectively fixedly connected to the top of the two digging plates 24. The fixed end and telescopic end of the telescopic drive component 251 are respectively hinged to one end of the two horizontal arms 252 through hinge seats. The telescopic drive component 251 includes an electric push rod. The two lugs 253 are respectively fixedly connected to the top surface of the other end of one horizontal arm 252 and the bottom surface of the other end of the other horizontal arm 252. The two ends of the inclined connecting rod 254 are respectively hinged to the two lugs 253. During operation, the telescopic drive 251 drives the two digging plates 24 to move towards or away from each other, thus turning the digging plates 24 into an opening and closing action. The two ends of the tilting link 254 are respectively hinged to the lugs 253 of the two horizontal arms 252, so that the movement trajectory of the two horizontal arms 252 remains symmetrical, ensuring that the opening and closing angle and speed of the digging plates 24 are synchronized, thereby avoiding uneven load caused by uneven force on one side.
[0054] In this embodiment, please refer to Figure 1 , Figures 5 to 8The electro-hydraulic rotating assembly 26 includes a fixed cylinder 261, a rotating column 262, two annular sealing sleeves 263, a middle sealing cover 2611, a bottom sealing cover 2612, a power transmission module 264, and a liquid infusion module 265. The rotating column 262 is coaxially and fixedly connected at both ends to the middle sealing cover 2611 and the bottom sealing cover 2612, respectively. The fixed cylinder 261 is open at one end and closed at the other end, forming a rotating space 266. The rotating column 262 forms a rotational seal connection with the inner wall of the rotating space 266. The tops of the middle sealing cover 2611 and the bottom sealing cover 2612 are rotatably and sealingly connected to the inner wall of the rotating space 266 and the bottom of the fixed cylinder 261, respectively. The two annular sealing sleeves 263 are fitted onto the rotating column 262. The outer surface of the annular sealing sleeve 263 forms a static seal connection with the outer wall of the rotating column 262, and the outer circular surface of the annular sealing sleeve 263 forms a rotational seal connection with the inner wall of the rotating space 266. The outer circular surface of the annular sealing sleeve 263 has two annular flow channels 267, and the side wall of the fixed cylinder 261 has two inlet channels 268 that are respectively connected to the annular flow channels 267. The rotating column 262 has outlet channels 269 that are respectively connected to the two annular flow channels 267 in the axial direction. A sealing ring 2610 is provided between the annular sealing sleeve 263 and the outer wall of the rotating column 262 and the inner wall of the rotating space 266, and between the middle sealing cover 2611 and the inner wall of the rotating space 266. The bottom of the bottom sealing cover 2612 is coaxially and fixedly connected to the top of the seedling cylinder 21.
[0055] The power transmission module 264 is located in the rotating space 266 and is used to continuously supply power to the electrical components of the transplanting mechanism 2.
[0056] The infusion module 265 is used to connect the receiving cavities 27 on the two hollowing plates 24 to the two annular flow channels 267 respectively.
[0057] In use, the fixed cylinder 261 is fixed to the transplanter, and the two inlet channels 268 are connected to the water tank and fertilizer tank on the transplanter through a delivery pump and pipes, respectively. The water tank and fertilizer tank can be filled with water and / or liquid fertilizer as needed. The rotary drive mechanism drives the seedling cylinder 21 to rotate, which in turn drives the rotating column 262 to rotate. The rotating column 262 rotates within the rotating space 266. The rotating column 262 and the inner wall of the rotating space 266, and the outer surface of the annular sealing sleeve 263 and the inner wall of the rotating space 266 form a rotational seal connection, while the inner surface of the annular sealing sleeve 263 and the outer wall of the rotating column 262 form a static seal connection. Each key part is equipped with a sealing ring 2610, forming a multi-level seal and enhancing the sealing pressure resistance. This ensures a continuous and stable input of electricity, water, and / or liquid fertilizer during rotation, guaranteeing the reliability and stability of the system and extending the service life of the equipment. The electro-hydraulic rotating assembly 26 enables a continuous input of electricity, water, and / or liquid fertilizer while the transplanting mechanism 2 rotates.
[0058] In this embodiment, please refer to Figures 5 to 7 The power transmission module 264 includes multiple input conductive rings 2641, multiple arc-shaped output blocks 2642, an output disk 2643, and an elastic element 2644. The multiple input conductive rings 2641 are concentrically arranged at the top of the rotating space 266. Each input conductive ring 2641 has a different diameter. The multiple input conductive rings 2641 are concentrically arranged at the top of the rotating space 266 from near to far. The input conductive rings 2641 can be copper rings. Each input conductive ring 2641 connects to the positive and negative terminals of the power supply. One input conductive ring 2641... 641 corresponds to a positive or negative terminal. Multiple arc-shaped output blocks 2642 are concentrically arranged on the output disk 2643 from near to far. Each arc-shaped output block 2642 slides and is in one-to-one contact with each input conductive ring 2641. The output disk 2643 rotates and engages with the inner wall of the rotating space 266. The number of input conductive rings 2641 and arc-shaped output blocks 2642 can be determined according to actual application needs. The arc-shaped output blocks 2642 are electrically connected to the rotating power component 34 and the telescopic drive component 251.
[0059] The elastic element 2644 provides a thrust to the top side of the rotation space 266 for the output disk 2643; the elastic element 2644 includes a spring, the two ends of which are fixedly connected to the bottom of the output disk 2643 and the top of the middle sealing disk, respectively. The spring provides a thrust to the output disk 2643, ensuring that the arc-shaped output block 2642 maintains good contact with the input conductive ring 2641, thereby improving the stability and reliability of power transmission.
[0060] The middle cover 2611, the rotating column 262 and the bottom cover 2612 are provided with a wire laying channel 2613 at their axis, which provides a dedicated path for the arrangement of wires.
[0061] The positive and negative terminals of the power supply are connected through the input conductive ring 2641, with one input conductive ring 2641 corresponding to one positive or negative terminal. The arc-shaped output block 2642 is connected to the electrical components on the transplanting mechanism 2 via wires. When the rotating column 262 rotates with the transplanting mechanism 2, the arc-shaped output block 2642 rotates synchronously. The arc-shaped output block 2642 is always in contact with the input conductive ring 2641, thus achieving circuit connection while rotating. At the same time, the annular sealing sleeve 263 statically seals the rotating column 262 and the rotating air... A rotating seal is formed on the inner wall of the space 266. Water and / or liquid fertilizer input through the inlet channel 268 enter the receiving cavity 27 on the hole-digging plate 24 through the annular flow channel 267, the outlet channel 269, the first infusion pipe 2651, the spiral pipe 2652, and the second infusion pipe 2653 on the outer circular surface of the annular sealing sleeve 263. This enables the delivery of water and / or liquid fertilizer at the same time as the electrical transmission, and realizes the connection of the liquid circuit. Thus, the transplanting mechanism 2 can continuously maintain the transmission of liquid and electricity when it rotates.
[0062] In this embodiment, please refer to Figure 8 The infusion module 265 has two components, and the two infusion modules 265 are respectively connected to the two outflow channels 269;
[0063] Each of the infusion modules 265 includes a first infusion tube 2651, a spiral tube 2652, and a second infusion tube 2653. One end of the first infusion tube 2651 is connected to the outflow channel 269. The two ends of the spiral tube 2652 are respectively connected to the other end of the first infusion tube 2651 and one end of the second infusion tube 2653. The other end of the second infusion tube 2653 is connected to the receiving cavity 27. The spiral tube 2652 has a certain elasticity and a certain hardness, which allows it to meet the requirements of vertical extension and contraction and continuous and uniform supply of water and / or liquid fertilizer when the transplanting mechanism 2 digs holes, thus improving the stability of the delivery state. The other end of the second infusion tube 2653 is connected to the receiving cavity 27.
[0064] The seedling tray 21 and the seedling delivery tray 23 each have a first tube storage space 2654 and a second tube storage space 2655 along their own axial direction. The first infusion tube 2651 and the second infusion tube 2653 are located in the first tube storage space 2654 and the second tube storage space 2655, respectively. The first tube storage space 2654 and the second tube storage space 2655 can accommodate pipelines. The first tube storage space 2654 and the second tube storage space 2655 set in the seedling tray 21 and the seedling delivery tray 23 make reasonable use of the internal space of the transplanting mechanism 2, hide the infusion tubes in them, make the structure of the entire transplanting mechanism 2 more compact, and avoid the mess of external pipelines.
[0065] In this embodiment, please refer to Figure 9Each of the transplanting mechanisms 2 further includes a centering component 211, which is used to adjust the seedling to the central axis of the seedling delivery tube 23 and slow down the falling speed of the seedling;
[0066] The centering assembly 211 includes an air collecting chamber 2111 coaxially fixed within the seedling feeding cylinder 21, an air source 2112 disposed on the outer wall of the seedling feeding cylinder 21 for supplying air to the air collecting chamber 2111, a first position sensor 2113 disposed below the seedling feeding port 210, a second position sensor 2114 disposed below the air collecting chamber 2111, and a control valve 2115 for controlling the opening or closing of the air source 2112. The air source 2112 may be a blower. The air collecting chamber 2111 has a frustum-shaped through hole 2116 along its own axial direction, which is larger at the top and smaller at the bottom and coaxial with the seedling tube 21. The side wall of the frustum-shaped through hole 2116 has several inclined air outlet holes 2117 facing the central axis of the seedling tube 21 and discharging air upwards. The diameter of the inclined air outlet holes 2117 gradually decreases from top to bottom in the frustum-shaped through hole 2116. Air is supplied to the inclined air outlet holes 2117 through the air source 2112, which is connected to the air collecting chamber 2111. The air source 2112, control valve 2115, first position sensor 2113 and second position sensor 2114 are electrically connected to the arc-shaped output block 2642.
[0067] During transplanting, the air source 2112 is turned on only when needed through the cooperation of sensors and control valve 2115, reducing energy consumption and lowering operating costs. The first position sensor 2113 is located below the seedling inlet 210, and the second position sensor 2114 is located below the air collection chamber 2111. They can monitor the position of the seedling in real time. When the seedling reaches the corresponding position, the control valve 2115 controls the air source 2112 to open according to the sensor signal. The air source 2112 supplies air into the air collection chamber 2111, and the gas exits from the air collection chamber 2111 to each inclined air outlet 2117, forming an upward airflow. This ensures that the seedling is positioned on the central axis of the seedling delivery cylinder 23, ensuring that the seedling falls into the center of the dug hole, effectively protecting the uprightness of the seedling. It also generates an upward reaction force on the seedling, reducing the falling speed of the seedling and thus avoiding damage to the seedling due to excessive falling speed.
[0068] It also includes two infrared sensor probes, which are respectively located inside the two seedling tubes 23 and below the second position sensor 2114. The infrared sensor probes are electrically connected to the arc-shaped output block 2642. The infrared sensor probes collect signals and send them to a mobile terminal device via a wireless module. The mobile terminal device can be a mobile phone or a computer. The infrared sensor probes transmit the detected data to the mobile terminal device via the wireless module. The relevant collected data can be viewed on the program in the mobile terminal device, which is convenient for monitoring and statistics.
[0069] In this embodiment, please refer to Figure 9 The inclined angle of the inclined air outlet 2117 is 30~45°. The inclined angle of the inclined air outlet 2117 is preferably 37.5°. The inclined angle of 37.5° can make the gas form a stable diffusion angle after it is ejected, thereby improving the utilization efficiency of the gas.
[0070] In this embodiment, please refer to Figure 1 and Figure 10 It also includes two soil covering mechanisms 212 respectively located behind the transplanting mechanism 2;
[0071] The soil covering mechanism 212 includes an L-shaped connecting arm 2121 and two soil covering wheels 2122. The horizontal end of the L-shaped connecting arm 2121 is fixedly connected to the parallelogram frame 11 above. The two soil covering wheels 2122 are symmetrically arranged on both sides of the vertical end of the L-shaped connecting arm 2121, with the top of the wheels 2122 inclined downwards. During the soil covering process, the two soil covering wheels 2122, symmetrically arranged on both sides of the vertical end of the L-shaped connecting arm, can simultaneously cover the transplanted seedlings from both sides, ensuring that the soil around the roots of the seedlings is evenly covered, improving the soil covering effect, helping the seedling roots to form a tight bond with the soil, and promoting their growth. The symmetrical and inclined soil covering wheels 2122 can gently cover the soil to the roots of the seedlings during the soil covering process, reducing the risk of damage to the stems and leaves of the seedlings, which is beneficial to the survival and normal growth of the seedlings after transplanting.
[0072] It also includes two seedling leakage monitoring mechanisms 213, which are respectively located behind the soil covering mechanism 212. Each seedling leakage monitoring mechanism 213 includes an L-shaped connecting frame 2131, a U-shaped frame 2132, a signal transmitter 2133, and a signal receiver 2134. The horizontal end of the L-shaped connecting frame 2131 is fixedly connected to the intersection of the vertical and horizontal parts of the L-shaped connecting arm 2121. The U-shaped frame 2132 is fixedly connected to the vertical end of the L-shaped frame. The signal transmitter 2133 is located inside one side of the U-shaped frame 2132, and the signal receiver 2134 is located inside the other side of the U-shaped frame 2132. The signal transmitter 2133 and the signal receiver 2134 are arranged opposite to each other. The time difference between two adjacent seedlings transmitted through the signal transmitter 2133 and the signal receiver 2134 is compared with the time difference set for continuous planting. If the former is greater than the latter, it indicates that the seedling was missed; if the former is less than the latter, it indicates that the seedling was replanted. When the seedling is missed or replanted, an alarm is triggered by the alarm module, which facilitates quick processing and improves the quality of transplanting.
[0073] In this embodiment, please refer to Figures 1 to 10 A vegetable transplanter, comprising the aforementioned transplanting device.
[0074] Working principle: During use, the fixed cylinder 261 and the upper parallelogram frame 11 are both fixed on the vegetable transplanter. The seedling release cylinder 21 is vertically and rotatably installed on the upper parallelogram frame 11, and the seedling delivery cylinder 23 is vertically and rotatably installed on the lower parallelogram frame. The limiting groove 29 on the circumferential direction of the inner wall of the seedling delivery cylinder 23 slides and engages with the protrusion 22 at the bottom of the outer wall of the seedling release cylinder 21. This allows the seedling release cylinder 21 to drive the seedling delivery cylinder 23 to rotate synchronously when driven by the rotary drive mechanism. It can also move up and down under the drive of the telescopic power component 12, ensuring the stable and continuous delivery of seedlings from the seedling release cylinder 21 to the seedling delivery cylinder 23. The two symmetrically arranged and hinged digging plates 24 below the seedling delivery cylinder 23 fit together to form a cone-shaped structure, which is conducive to cutting into the soil for digging holes, reducing soil resistance, and improving digging efficiency. The spiral groove on the digging plate 24 can guide the soil to move upward during the digging process, further reducing digging resistance and making the digging holes more regular.
[0075] The positive and negative terminals of the power supply are connected through the input conductive ring 2641, with one input conductive ring 2641 corresponding to one positive or negative terminal. The arc-shaped output block 2642 is connected to the electrical components on the transplanting mechanism 2 via wires. When the rotating column 262 rotates with the transplanting mechanism 2, the arc-shaped output block 2642 rotates synchronously. The arc-shaped output block 2642 is always in contact with the input conductive ring 2641, thus achieving circuit connection while rotating. At the same time, the annular sealing sleeve 263 statically seals the rotating column 262 and the rotating air... A rotating seal connection is formed on the inner wall of the space 266. Water and / or liquid fertilizer input through the inlet channel 268 enter the receiving cavity 27 on the hole-digging plate 24 through the annular flow channel 267, the outlet channel 269, the first infusion pipe 2651, the spiral pipe 2652 and the second infusion pipe 2653 on the outer circular surface of the annular sealing sleeve 263. This enables the delivery of water and / or liquid fertilizer at the same time as the electrical transmission, and realizes the connection of the liquid circuit. Thus, the transplanting mechanism 2 can continuously maintain the transmission of liquid and electricity when rotating.
[0076] The second infusion pipe 2653 connects to the receiving cavity 27 on the planting plate 24, allowing water and / or liquid fertilizer to form a liquid surface on the conical surface of the planting plate 24 through the seepage hole 28. This isolates the soil or reduces direct contact, achieving both anti-sticking and anti-clogging effects, and enabling the application of root-setting water and / or liquid fertilizer during transplanting. This provides a good growth environment for seedlings, improving transplanting efficiency and survival rate, thus solving problems such as easy clogging, poor transplanting quality, low efficiency, and low seedling survival rate. The parallelogram frame 11 design allows for staggered planting of seedlings between adjacent narrow rows on the ridge, followed by continuous transplanting by a vegetable transplanter traveling along the ridge length. The distance the vegetable transplanter travels is equal to the planting distance between adjacent seedlings in the same row, creating a triangular staggered planting pattern between adjacent seedlings in adjacent rows. This optimizes planting density and spatial layout, improving crop growth conditions and yield.
[0077] In summary, this invention enables efficient and continuous transplanting operations by driving two transplanting mechanisms 2 to rotate simultaneously through a rotary drive mechanism, thereby improving work efficiency. Furthermore, the synchronous rotation ensures consistency in the actions and transplanting depth of the two transplanting mechanisms 2, which helps guarantee the uniformity and standardization of transplanting, thus improving the overall transplanting quality and ensuring the consistency and uniformity of seedling growth. The design of the parallelogram frame 11 allows for staggered transplanting of seedlings between adjacent narrow rows on the ridge, optimizing planting density and spatial layout, and improving crop growth conditions and yield. The seedling release tube 21 is vertically and rotatably mounted on the upper parallelogram frame 11, and the seedling delivery tube 23 is vertically and rotatably mounted on the lower parallelogram frame 11. The circumferential limiting groove 29 on the inner wall of the seedling delivery tube 23 slides into contact with the protrusion 22 on the bottom of the outer wall of the seedling release tube 21. This allows the seedling release tube 21 to drive the seedling delivery tube 23 to rotate synchronously when the rotary drive mechanism rotates, and also allows it to move up and down under the drive of the telescopic power component 12. This ensures a stable and continuous transport of seedlings from the seedling release tube 21 to the seedling delivery tube 23. Two symmetrically arranged and hinged digging plates 24 below the seedling delivery tube 23 fit together to form a conical structure, which facilitates digging holes by cutting into the soil, reducing soil resistance, and improving digging efficiency. The spiral grooves on the 24 plate guide the soil upwards during digging, further reducing digging resistance and making the holes more regular. The electro-hydraulic rotating component 26 continuously delivers electricity, water, and / or liquid fertilizer. Through communication with the receiving cavity 27 on the digging plate 24, water and / or liquid fertilizer can form a liquid surface on the conical surface of the digging plate 24 through the seepage holes 28, isolating the soil or reducing direct contact. This achieves both anti-sticking and anti-clogging effects, and also enables the application of root-setting water and / or liquid fertilizer during transplanting, providing a good growth environment for seedlings and improving transplanting efficiency and survival rate. This solves the problems of easy clogging, poor transplanting quality, low efficiency, and low seedling survival rate. The integrated design of digging and watering / / or fertilizing not only improves planting efficiency and reduces operational steps, but also allows for precise watering and / or fertilization of seedlings during planting, ensuring they receive the necessary water and nutrients, promoting seedling survival and early growth. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
