Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco planting technology, and in particular to a planting device and a transplanter. Background Technology
[0002] Digging pits refers to excavating pits of a certain depth and diameter in farmland using manual labor or machinery to facilitate crop planting. Its main purpose is to provide a favorable growing environment for crops, ensuring suitable soil temperature and good aeration.
[0003] In current operations, the two related steps of planting holes and transplanting are usually completed separately by specialized tobacco planting holes machines and tobacco seedling transplanters. That is, workers first use the planting hole machine to create the holes, and then use the transplanter to plant the tobacco seedlings into the pre-dug holes. However, due to varying road conditions in different parts of the farmland, the transplanter cannot accurately plant the seedlings into the pre-dug holes at the set distance, resulting in misalignment between the planted seedlings and the holes. This affects the effectiveness of subsequent watering and fertilization, causing slow seedling growth.
[0004] Therefore, there is an urgent need for a pond-digging device and a transplanting machine to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a seedbed preparation device and a transplanter, which can solve the problem that in the process of transplanting tobacco seedlings, due to the different road conditions in different parts of the farmland, the transplanter cannot accurately plant the seedlings into the pre-prepared seedbeds at the set distance, resulting in misalignment between the seedlings and the seedbeds after planting, which affects the effect of subsequent watering and fertilization of the seedlings and causes slow growth of the seedlings.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] On one hand, this utility model provides a seedling-digging device, which is mounted on the body of a transplanter. The transplanter also includes a seedling-transferring mechanism, which can drive the tobacco seedlings to rise and fall, inserting the tobacco seedlings into the center of the seedling-digging area. The seedling-digging device includes:
[0008] The four-bar linkage includes a base, a first swing arm, a second swing arm, and a main swing arm. The first and second swing arms are arranged opposite to each other. The base includes a first connecting area and an assembly area. The middle position of the first swing arm and the first end of the second swing arm are rotatably connected to the first connecting area. The main swing arm includes a second connecting area and an installation area. The tail ends of the first and second swing arms are rotatably connected to the second connecting area. The assembly area of the base is connected to the machine body. The first swing arm is connected to the seedling transplanting mechanism via a steel wire rope.
[0009] The equipment includes a planting drill and a driving component. The planting drill is fixedly installed in the installation area. The installation area and the transplanting mechanism are spaced apart in the horizontal direction. The size of the distance between adjacent tobacco seedlings is equal to the plant spacing. The driving component is fixedly placed on the machine body and is opposite to the planting drill. The driving component is connected to the planting drill via a connecting shaft.
[0010] As a preferred technical solution for the pond-digging device, the first connecting area is hinged to the middle position of the first swing arm and the first end of the second swing arm by a first pin.
[0011] The second connecting area is hinged to both the second swing arm tail end and the second swing arm tail end via a second pin.
[0012] As a preferred technical solution for the pit-digging device, the assembly area includes two opposing clamping clips and a connecting beam. The connecting beam connects the two clamping clips, and the two clamping clips are connected to the machine body through fasteners. The connecting beam has clearance holes, and the pit-digging drill part is placed in the clearance holes.
[0013] As a preferred technical solution for the dredging device, the axes of the two clamping clips are perpendicular to the straight line along the length direction of the machine base.
[0014] As a preferred technical solution for the pond-digging device, the first swing arm has a wire hole at its head end, and the steel wire rope passes through the wire hole and is connected to the seedling transplanting mechanism.
[0015] As a preferred technical solution for the pond-digging device, the installation area includes an installation hole, a bearing is provided in the installation hole, the pond-digging drill includes a drill bit and a connecting column, the connecting column is placed in the inner ring of the bearing, the connecting column includes a polygonal hole, and one end of the connecting shaft is inserted into the polygonal hole.
[0016] As a preferred technical solution for the pond-dredging device, the pond-dredging device further includes a pressure cap and two locking nuts. The pressure cap is provided on the mounting hole and has a receiving space. The locking nuts are threadedly connected to the connecting column. The two locking nuts are arranged sequentially along the height direction and are both placed in the receiving space. The locking nut near the mounting area is in contact with the inner ring of the bearing.
[0017] As a preferred technical solution for the pond-dredging device, the pressure cap is provided with a through hole, the connecting shaft passes through the through hole and is inserted into the polygonal hole, and the pond-dredging device also includes a steel wire hose, which is placed between the inner wall of the through hole and the connecting shaft.
[0018] As a preferred technical solution for the pit-digging device, the drill bit of the pit-digging drill is conical.
[0019] On the other hand, this utility model provides a transplanter, including the pond-digging device described in any of the above claims. The transplanter also includes a machine body and a seedling transplanting mechanism. The pond-digging device is fixedly placed on the machine body, and the seedling transplanting mechanism is connected to the pond-digging device by a steel wire rope.
[0020] The beneficial effects of this utility model are as follows:
[0021] The planting device of this utility model is connected to the body of a transplanter. When the transplanter moves, it drives the planting device to move synchronously. The first and second swing arms are positioned opposite each other, and both the first and second swing arms are rotatably connected to the first connecting area in the base and the second connecting area in the main swing arm. This allows the main swing arm and the second swing arm to perform corresponding coordinated movements when the first swing arm rotates relative to the first connecting area. The main swing arm swings, and the first swing arm is connected to the transplanting mechanism via a steel wire rope. Therefore, when the transplanting mechanism moves the seedlings up and down, it causes the first swing arm to rotate relative to the first connecting area, and the main swing arm to swing. The planting drill is fixedly installed in the mounting area of the main swing arm. When the main swing arm swings, it drives the planting drill to move up and down, that is, the transplanting mechanism moves the tobacco seedlings. During the raising and lowering process, the drilling drill will also be raised and lowered simultaneously. The distance between the installation area and the transplanting mechanism is the same as the plant spacing between adjacent tobacco seedlings set by the transplanter. In this way, when the transplanter moves along the farmland, the drilling and transplanting work can be carried out simultaneously, and the spacing between the seedlings and the plant spacing are equal. That is, when a tobacco seedling is transplanted, the drilling drill will simultaneously drill a hole in front of the plant spacing set by the transplanter. When the transplanter continues to move without changing direction, the next tobacco seedling can be accurately inserted into the center of the corresponding hole. This can avoid the problem of misalignment between the tobacco seedling and the seedling center when the moving mechanism pulls the seedling into the center of the seedling, thereby ensuring the effect of subsequent watering and fertilization of the tobacco seedlings and enabling the tobacco seedlings to grow vigorously.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] like Figures 1 to 6 As shown in the illustration, this embodiment provides a seedling-digging device, which is mounted on the body of a transplanter. When the transplanter moves in the field, it drives the seedling-digging device to move synchronously. The transplanter also includes a seedling-transferring mechanism, which can raise and lower tobacco seedlings to insert them into the seedling center. The seedling-digging device includes a four-bar linkage 1, a seedling-digging drill 2, and a drive component. The four-bar linkage 1 includes a base 11, a first swing arm 12, a second swing arm 13, and a main swing arm 14. The first swing arm 12 and the second swing arm 13 are arranged opposite to each other. The base 11 includes a first connecting area 111 and an assembly area 112. The middle area of the first swing arm 12 and the head end of the second swing arm 13 are rotatably connected to the first connecting area 111. The main swing arm 14 includes a second connecting area 141 and an installation area 142. The tail ends of the first swing arm 12 and the tail ends of the second swing arm 13 are rotatably connected to the second connecting area 141. Thus, when the first swing arm 12 is rotated by an external force, the main swing arm 14 and the second swing arm 13 will move in a coordinated manner accordingly. The assembly area 112 of the base 11 is connected to the machine body so that the transplanter can move together with the pond-digging device when it moves. The first swing arm 12 is connected to the seedling transplanting mechanism through a steel wire rope. When the seedling transplanting mechanism is working, it will drive the tobacco seedlings to rise and fall so as to insert the tobacco seedlings into the center of the pond. Therefore, when the seedling transplanting mechanism is working, it will drive the first swing arm 12 to move at the same time. The main swing arm 14 and the second swing arm 13 will move in coordination, so that the main swing arm 14 swings.
[0038] The drilling rig 2 is fixedly placed in the installation area 142. When the main swing arm 14 swings, it will drive the drilling rig 2 to rise and fall, allowing it to be inserted into the farmland. That is, when the transplanting mechanism moves the tobacco seedlings up and down, it will simultaneously move the drilling rig 2 up and down. A horizontal gap is left between the installation area 142 and the transplanting mechanism to avoid interference between the drilling rig 2 and the transplanting mechanism. The distance between the installation area 142 and the transplanting mechanism is the plant spacing between adjacent tobacco seedlings set by the transplanter. This allows the digging and transplanting processes to proceed simultaneously as the transplanter moves along the field, ensuring that the spacing between the seedling centers and the plant spacing are equal. Specifically, when a seedling is transplanted, the digging drill 2 simultaneously creates a hole in front of the seedling at the set plant spacing. As the transplanter continues moving without changing direction, the next seedling can be accurately inserted into the corresponding hole. This avoids misalignment between the seedling and the seedling center when the moving mechanism inserts the seedling, thus ensuring the effectiveness of subsequent watering and fertilization, allowing the seedlings to grow vigorously. The drive unit is fixed to the machine body and opposite the digging drill 2. The drive unit is connected to the digging drill 2 via a connecting shaft 3. Once the digging drill 2 is inserted into the field, the drive unit can be activated to rotate the digging drill 2, enabling rapid completion of the digging process.
[0039] It should be noted that transplanters are standard equipment in the planting field, and their specific structure and working principle can be found in existing technologies, so they will not be elaborated here.
[0040] In this embodiment, the driving component can be a motor, specifically a servo motor, a stepper motor, a synchronous motor, or an asynchronous motor. No specific restrictions are placed on the type of motor used.
[0041] Preferably, the straight-line distance between the middle position and the tail end of the first swing arm 12 is equal to the straight-line distance between the head end and the tail end of the second swing arm 13, and the distance between the middle position of the first swing arm 12 and the head end of the second swing arm 13 in the first connecting area 111 is equal to the distance between the tail ends of the first swing arm 12 and the tail ends of the second swing arm 13 in the second connecting area 141. Thus, the four-bar linkage 1 formed between the first swing arm 12, the second swing arm 13, the main swing arm 14, and the base 11 is theoretically a parallelogram, which can further improve the stability of the deformation process of the four-bar linkage 1 when the transplanting mechanism drives the first swing arm 12 to move.
[0042] Specifically, the first connecting area 111 is hinged to the middle position of the first swing arm 12 and the first end of the second swing arm 13 by the first pin 15. The middle position of the first swing arm 12 and the first end of the second swing arm 13 are provided with first openings. The first connecting area 111 is provided with two spaced first mounting holes. After the first pin 15 passes through the first opening and the first mounting holes, the two ends of the first pin 15 are locked by nuts, thus completing the assembly of the first connecting area 111 with the middle position of the first swing arm 12 and the first end of the second swing arm 13. Furthermore, the second connecting area 141 is hinged to the tail ends of the first swing arm 12 and the second swing arm 13 via the second pin 16. The tail ends of the first swing arm 12 and the second swing arm 13 are provided with second openings. The second connecting area 141 is provided with two spaced second mounting holes. After the second pin 16 passes through the second opening and the second mounting hole, both ends of the second pin 16 are locked with nuts, thus completing the assembly of the second connecting area 141 with the tail ends of the first swing arm 12 and the second swing arm 13, thereby completing the assembly of the first swing arm 12, the second swing arm 13, the main swing arm 14 and the base 11.
[0043] For example, such as Figure 1 and Figure 3 As shown, the assembly area 112 includes two opposing clamping clips 1121 and a connecting beam 1122. The connecting beam 1122 connects the two clamping clips 1121, and the two clamping clips 1121 are connected to the machine body via fasteners, thus ensuring a stable connection between the assembly area 112 and the machine body. By tightening the fasteners, the machine base 11 can be disassembled and connected to the machine body, facilitating subsequent maintenance and assembly of the drilling device. Specifically, bolts can be used as fasteners. The connecting beam 1122 has clearance holes, and the drilling drill 2 is placed within these clearance holes. This prevents interference between the drilling drill 2 and the connecting beam 1122, allowing for a more rational layout of the drilling drill 2 and the machine base 11, thus improving the design rationality of the drilling device. The shape of the clearance holes can be elliptical, circular, square, or irregular, and no specific limitations are imposed here. Furthermore, the axes of the two clamping clips 1121 are perpendicular to the straight line along the length of the base 11, which makes it easier for the two clamping clips 1121 to be fitted and assembled with the machine body, reducing the assembly difficulty for the staff.
[0044] In this embodiment, as Figure 1 and Figure 4 As shown, the first swing arm 12 has a wire hole 121 at its head end. The wire rope passes through the wire hole 121 and is connected to the seedling transplanting mechanism. In this way, when the seedling transplanting mechanism drives the pond-digging device to rise and fall, the deformation of the four-bar linkage 1 can be adjusted from the head end of the first swing arm 12, which can make the force on the wire rope more stable and the force on the four-bar linkage 1 more stable during the deformation process.
[0045] For example, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the mounting area 142 includes a mounting hole 1421, within which a bearing 6 is installed. The pond drilling drill 2 includes a drill bit 21 and a connecting post 22. The connecting post 22 is placed within the inner ring of the bearing 6. When the driving component drives the pond drilling drill 2 to rotate via the connecting shaft 3, the bearing 6 ensures smoother operation of the drill 2 during rotation. The connecting post 22 includes a polygonal hole 221. One end of the connecting shaft 3 is inserted into the polygonal hole 221. The shape of the end of the connecting shaft 3 inserted into the polygonal hole 221 matches the shape of the polygonal hole 221, thus preventing the connecting shaft 3 and the polygonal hole 221 from twisting and reducing the risk of pond center misalignment when the pond drilling drill 2 is used to drill ponds in farmland. In this embodiment, the polygonal hole 221 can be a square hole, a pentagonal hole, or a hexagonal hole, without specific limitations. A square hole is preferred, as this reduces the machining difficulty of the connecting shaft 3.
[0046] Furthermore, the drilling rig 2 also includes a pressure cap 7 and two locking nuts 8. The pressure cap 7 covers the mounting hole 1421 and has a receiving space. The locking nuts 8 are threadedly connected to the connecting post 22. The two locking nuts 8 are arranged sequentially along the height direction and are both placed within the receiving space. The locking nut 8 closer to the mounting area 142 is in contact with the inner ring of the bearing 6. The locking nuts 8 prevent the bearing 6 from shifting during operation, further improving the smoothness of the drilling rig 2 when driven by the drive component. By setting two locking nuts 8, the risk of the locking nuts 8 in contact with the inner ring of the bearing 6 is reduced, improving the durability of the drilling device. The pressure cap 7 is fixed in the mounting area 142 by bolts, preventing the locking nuts 8 from falling off.
[0047] Furthermore, the pressure cap 7 is provided with a through hole, and the connecting shaft 3 passes through the through hole and is inserted into the polygonal hole 221. The pit drilling rig 2 also includes a steel wire hose 9, which is placed between the inner wall of the through hole and the connecting shaft 3. The setting of the steel wire hose 9 can limit the range of motion of the connecting shaft 3, further reduce the range of pit center deviation, and further reduce the risk of tobacco seedlings being misaligned with the pit center during transplanting.
[0048] In this embodiment, the drill bit 21 of the pit drilling drill 2 is conical. The conical tip structure allows the pit drilling drill 2 to penetrate the soil more easily, especially in hard or dense soil layers, effectively reducing the resistance of the soil to the drill bit 21, thereby accelerating the pit drilling speed and improving the pit drilling efficiency. The drill bit 21 of the pit drilling drill 2 can be a hexagonal pyramidal conical structure or a pentagonal pyramidal conical structure; no specific limitation is made here.
[0049] This embodiment provides a transplanter, including the above-mentioned pond-digging device. The transplanter includes a body and a seedling transplanting mechanism. The pond-digging device is fixedly placed on the body, and the seedling transplanting mechanism is connected to the pond-digging device by a steel wire rope.
[0050] The transplanter provided in this embodiment, when the transplanting mechanism inserts the tobacco seedling into the center of the planting pit, the pit-digging device simultaneously digs a new pit directly in front of the seedling, and the pit and the seedling are on the same straight line. When the next seedling is inserted into the pit, the seedling can be accurately planted in the center of the pit, effectively solving the problem of misalignment between the seedling and the planting pit after planting, and ensuring that the seedling can grow vigorously.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
