Technical Field
[0001] This utility model relates to the field of tobacco planting equipment technology, specifically a tobacco transplanter. Background Technology
[0002] As a single-person agricultural tool, the tobacco transplanter can transplant tobacco seedlings from the nursery to the field for planting. It is suitable for small-scale planting in irregular terrains such as hills and mountains. One tool can complete tasks such as digging holes, placing seedlings, and covering with soil, reducing labor intensity and improving the efficiency of single-person operation. To improve the survival rate of tobacco, transplanting needs to be done according to the set plant spacing. To achieve this function, existing transplanters are usually equipped with positioning rulers, which are basically fixed. However, when transplanting seedlings at different growth stages, the digging depth and plant spacing need to be adjusted accordingly. This requires replacing the positioning ruler with a suitable one and adaptively adjusting the installation height, which brings trouble to actual production and affects the efficiency and quality of tobacco transplanting to a certain extent. Summary of the Invention
[0003] The purpose of this invention is to provide a tobacco transplanter equipped with a positioning ruler that allows for adaptive adjustment of installation height and plant spacing, eliminating the need for disassembly and replacement, and solving the problems in the prior art.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a tobacco transplanter, comprising two uprights arranged side by side, each upright having a handle on its upper side and a digging scoop installed on its lower side. The digging scoops on both sides are hinged together. When the handle is moved away, the digging scoops on both sides rotate and close; when the handle is moved closer, the digging scoops on both sides rotate and open. A guide cylinder is installed on one upright, located above the digging scoop. A positioning ruler that can be vertically raised and lowered is installed on the other upright. The upright with the positioning ruler has a T-shaped vertical groove, and a T-shaped block is installed in the T-shaped vertical groove. A nut is installed on the T-shaped block, and one end of the positioning ruler is installed in the nut. A positioning bolt is installed on the T-shaped block, and rotating the positioning bolt can lock the T-shaped block at a specified height position in the T-shaped vertical groove. A rotatable turntable is mounted on the T-block, with a nut fixed to it. A horizontally arranged lower support is connected to the outside of the T-block, and an upper limit seat is hinged to the lower support for rotatable engagement. A positioning ruler is horizontally positioned between the lower support and the upper limit seat. A hook is mounted on the end of the positioning ruler away from the nut, and a hanging ring is provided on the upright to engage with the hook. When the positioning ruler rotates to coincide with the upright, the hook can enter the hanging ring to lock the positioning ruler in place. The guide cylinder is fixed to the upright via a connecting plate and is inclined to the upright. When the handle is moved close to the digging scoops on both sides and rotated to open, the guide cylinder moves to a vertical position. An opening and closing assist device is installed between the two uprights. This device includes a guide post mounted horizontally on one upright and a rotatable assisting pressure plate mounted on the other upright. One end of the assisting pressure plate is hinged to the upright, and the other end has a pressing handle. A guide groove is also provided on the assisting pressure plate to cooperate with the guide post. When the pressing handle is pressed, the guide groove squeezes the guide post, allowing the two uprights to move closer together, thus assisting in the rotation and opening of the digging scoop. The guide post is mounted on the upright where the T-block is installed, and the assisting pressure plate is hinged to the upright where the guide cylinder is installed. The T-block also has a foot pedal, and the upright has a clearance groove that cooperates with the foot pedal. The clearance groove is connected to the vertical groove of the T-block. The foot pedal and the positioning ruler are located on the front and rear sides of the upright, respectively. The foot pedal is horizontally arranged and can rise and fall synchronously with the positioning ruler.
[0005] The positive effects of this utility model are as follows: The tobacco transplanter described herein features a rotatable, openable pole with a handle at the top and a digging scoop at the bottom. The digging scoop has a guide tube at the top for placing tobacco seedlings. A vertically lifting and horizontally extending positioning ruler is also installed on the pole. Through this structure, tobacco farmers can easily adjust the height of the positioning ruler according to the required digging depth and plant spacing for tobacco seedlings at different growth stages, without needing to replace different sized positioning rulers. This significantly improves the flexibility of transplanting operations and adaptability to different planting needs, effectively shortens preparation time, and increases transplanting efficiency. By precisely controlling the transplanting depth and plant spacing, this transplanter helps ensure even distribution of tobacco seedling roots and soil coverage, providing a more suitable growth environment for the seedlings, promoting healthy tobacco growth, increasing the survival rate after transplanting, and ultimately improving tobacco yield and quality.

[0013] Figure 8 This is a schematic diagram of an opening and closing assist device installed between the two uprights. Detailed Implementation
[0014] The tobacco transplanter described in this utility model, such as Figure 1 and Figure 2 As shown, the device includes two uprights 1 arranged side by side, each with a handle 2 on its upper side for the user to grip and control the movement and operation of the transplanter. A scoop 3 is mounted on the lower side of each upright 1, and the two scoops 3 are hinged together, allowing them to rotate and open / close under the influence of the handle 2.
[0015] When the handle 2 is moved away, the digging spoons 3 on both sides rotate and close, forming a relatively closed cone. The digging spoons 3 can be inserted downward into the soil to dig a hole on the ridge. Then, the tobacco seedlings are placed into the space formed by the digging spoons 3 on both sides. Then, the handle 2 is moved closer, and the digging spoons 3 on both sides rotate and open until the gap is wide enough for the tobacco seedlings to pass through when the digging spoons 3 are moved upward. After that, when the transplanter is lifted, it is ensured that the tobacco seedlings remain in the hole. After the transplanter is lifted, the soil can be automatically covered on the tobacco seedlings in the hole, thus realizing the transplanting operation of the tobacco seedlings.
[0016] To facilitate workers in accurately placing tobacco seedlings into the closed scoop 3, a guide cylinder 4 is installed on a pole 1. The guide cylinder 4 is located on the upper side of the scoop 3. The guide cylinder 4 can guide the placement of tobacco seedlings without the need for workers to bend over, which reduces the labor intensity of single-person operation to a certain extent.
[0017] To achieve the specified spacing between plants during transplanting, a vertically adjustable positioning ruler 5 is installed on another upright post 1. The positioning ruler 5 is generally located on the soil of the ridge and can also be extended and retracted horizontally. Tobacco seedlings at different growth stages have different digging depths and plant spacings during transplanting. To ensure the normal use of the positioning ruler 5, its vertical height and extension length need to be adjusted according to the transplanted tobacco seedlings to ensure that the positioning ruler 5 is always located on the soil under different digging depths and that the plant spacing meets the transplanting requirements of the tobacco seedlings at that growth stage.
[0018] To adjust the positioning ruler 5, such as Figure 3-5 As shown, the upright 1, on which the positioning ruler 5 is installed, has a T-shaped vertical groove 6. A T-shaped block 7 is installed within the T-shaped vertical groove 6, and the T-shaped block 7 can be raised and lowered vertically within the T-shaped vertical groove 6. A nut 8 is installed on the T-shaped block 7, and one end of the positioning ruler 5 is installed within the nut 8. By rotating the positioning ruler 5, the length of the ruler extending beyond the upright 1 can be adjusted to adapt to different plant spacing requirements. A positioning bolt 9 is installed on the T-shaped block 7. Rotating the positioning bolt 9 can lock the T-shaped block 7 at a specified height position within the T-shaped vertical groove 6. By loosening the positioning bolt 9, the vertical height of the T-shaped block 7 and the positioning ruler 5 can be adjusted. Tightening the positioning bolt 9 can fix the positioning ruler 5 at the specified height position.
[0019] When the transplanter is in use, the positioning ruler 5 is positioned horizontally outside the upright 1 to limit the spacing between plants. When the transplanter is not in use, the horizontally arranged positioning ruler 5 increases the storage space of the device, making it inconvenient to store. To solve the above problems and enable the positioning ruler 5 to switch between the use and storage states, a rotatable turntable 10 is installed on the T-block 7, and a nut 8 is fixedly set on the turntable 10. When the turntable 10 rotates, it can move the positioning ruler 5 to either the horizontal use state or the vertical storage state.
[0020] In order to achieve the limiting of the positioning ruler 5 in the horizontal use state and the vertical storage state respectively, a horizontally arranged lower support 11 is connected to the outside of the T-block 7. An upper limit seat 12 that can be rotated and fastened is hinged on the lower support 11. The positioning ruler 5 can be horizontally matched between the lower support 11 and the upper limit seat 12, and the positioning ruler 5 is maintained in the horizontal position through the upper and lower limits.
[0021] The positioning ruler 5 is equipped with a hook 14 at the end away from the nut 8. A hanging ring 13 that cooperates with the hook 14 is provided on the upright 1. When the transplanter is not in use, the upper limit seat 12 is opened, and the turntable 10 drives the positioning ruler 5 to rotate until it coincides with the upright 1. At this time, the hook 14 can enter the hanging ring 13, thereby realizing the hanging and locking of the positioning ruler 5, preventing the positioning ruler 5 from shaking or falling when not in use, and greatly reducing the space occupied by the overall transplanter.
[0022] Furthermore, the guide cylinder 4 can be fixed to the upright 1 by the connecting plate 15. The guide cylinder 4 is arranged at an angle to the upright 1. When the handle 2 is moved close to the digging spoons 3 on both sides and rotated to open, the guide cylinder 4 moves to a vertical state.
[0023] After the tobacco seedlings are placed into the digging scoop 3, the transplanter moves upward, leaving the seedlings in the pit. The upper part of the seedlings will be located at the bottom of the guide cylinder 4 after placement. As the digging scoop 3 rotates and opens, the guide cylinder 4 in the aforementioned position will move from an inclined position to a vertical position, which can straighten the seedlings inside. At the same time, it will not obstruct the placement of the seedlings during the upward movement, ensuring that the seedlings are left in the pit undamaged while moving upward smoothly. Before placing the seedlings, the slightly inclined guide cylinder 4 will not affect the accurate placement of the seedlings into the closed digging scoop 3.
[0024] If the soil for transplanting is too hard, the digging spoon 3 will encounter significant resistance during the rotation and opening process, thus affecting the normal lifting of the transplanter. To solve this problem, an opening and closing assist device can be installed between the two uprights 1, such as... Figure 8As shown, the opening and closing assist device includes a guide post 16 mounted on one upright post 1, which is horizontally arranged. A rotatable assisting pressure plate 17 is mounted on another upright post 1. One end of the assisting pressure plate 17 is hinged to the upright post 1, and the other end is fitted with a pressing handle 18. A guide groove 19 is also provided on the assisting pressure plate 17 to cooperate with the guide post 16. When the assisting device is needed, the assisting pressure plate 17 is rotated onto the guide post 16, and the pressing handle 18 is pressed to allow the guide groove 19 to press against the guide post 16, causing the upright posts 1 on both sides to move closer together, thus assisting in the rotation and opening of the scoop 3. This design can reduce the user's labor intensity to a certain extent.
[0025] Furthermore, to ensure that the upright 1 on which the positioning ruler 5 is installed does not tilt when using the above-mentioned assistive device, thus extending the service life of the positioning ruler 5, and simultaneously causing the upright 1 on which the guide cylinder 4 is installed to rotate and move closer together, so that the guide cylinder 4 changes from an inclined state to a vertical state, ensuring the normal progress of the transplanting operation, the guide post 16 is set on the upright 1 on which the T-block 7 is installed, and the assistive pressure plate 17 is hinged to the upright 1 on which the guide cylinder 4 is set.
[0026] The T-shaped block 7 is also provided with a foot pedal 20, and the upright 1 is provided with a clearance groove 21 that cooperates with the foot pedal 20. The clearance groove 21 is connected to the T-shaped vertical groove 6. The foot pedal 20 and the positioning ruler 5 are located on the front and rear sides of the upright 1, respectively. The foot pedal 20 is arranged horizontally and can be raised and lowered synchronously with the positioning ruler 5.
[0027] The foot pedal 20 has two advantages: firstly, it facilitates the user's downward stepping during the digging process, assisting the digging spoon 3 to enter the soil; secondly, when using the assist device, stepping on the foot pedal 20 presses it firmly against the soil surface, allowing the upright 1 with the positioning ruler 5 to remain vertical, preventing the positioning ruler 5 from rotating and colliding hard with the soil. At the same time, it allows the upright 1 with the guide cylinder 4 to rotate and tilt, changing the guide cylinder 4 from an inclined state to a vertical state, ensuring the normal operation of the tobacco seedling transplanting.
[0028] When using the tobacco transplanter of this utility model, the operator first adjusts the height and extension length of the positioning ruler 5 according to the growth cycle of the tobacco seedlings and the required transplanting spacing. At this time, the positioning ruler 5 is located between the lower support seat 11 and the upper limit seat 12, maintaining a horizontal position. Then, the operator holds the handle 2 with both hands and moves the transplanter to the transplanting position. Pulling the handle 2 away from each other allows the bottom digging spoon 3 to rotate and close. The operator steps down on the foot pedal 20 to assist the hands in exerting downward force, inserting the digging spoon 3 into the soil to dig a hole. Then, the tobacco seedling is placed into the digging spoon 3. Pulling the handle 2 closer together allows the bottom digging spoon 3 to rotate and open. The transplanter is then lifted upward, and the tobacco seedling remains in the dug hole, completing the transplanting operation. When transplanting the next tobacco seedling, the operator only needs to move the transplanter along the positioning ruler 5 to the designated position to achieve precise control of the plant spacing during transplanting.
[0029] The tobacco transplanter described in this utility model also has the following advantages:
[0030] Simplified operation process and improved efficiency: The adjustment of positioning ruler 5 is more convenient. Simply rotate positioning bolt 9 to quickly fix positioning ruler 5 at the required height. This simplifies the cumbersome steps of replacing positioning ruler 5 in the past, effectively shortens the preparation time for operation, and improves transplanting efficiency.
[0031] Enhancing the stability and safety of the positioning ruler 5: The combined use of the upper limit seat 12 and the lower limit support seat 11 not only provides additional support for the positioning ruler 5 to prevent it from shaking during operation, but also, through the design of the hook 14 and the hanging ring 13, enables the positioning ruler 5 to be safely hung when not in use, avoiding accidental drops that could cause damage or injury, thus enhancing the safety performance of the equipment.
[0032] The opening and closing mechanism of the digging spoon 3 has been optimized to reduce labor intensity: The introduction of the opening and closing assist device makes the opening and closing of the digging spoon 3 easier and smoother. By pressing down the handle 18 to drive the assist plate 17, the interaction between the guide groove 19 and the guide post 16 is utilized to open the digging spoon 3 with assistance, which significantly reduces the physical exertion of the operator and improves the comfort of operation.
[0033] Multifunctional design enhances practicality: The foot pedal 20 provides an auxiliary force point for the digging spoon 3 to dig downwards, while also ensuring that the upright 1 with the positioning ruler 5 is installed remains vertical. Furthermore, the clever combination of the clearance groove 21 and the T-shaped vertical groove 6 ensures that the lifting and lowering of the positioning ruler 5 is not interfered with, while increasing the multifunctionality of the equipment, making the operation more user-friendly, and improving the overall practicality.
[0034] In summary, this utility model of tobacco transplanter, through a series of innovative designs, effectively solves the problems existing in the prior art, significantly improves the flexibility, efficiency and safety of transplanting operations, and is of great significance to promoting the modernization of the tobacco planting industry.
