Description

Technical Field

[0001] This utility model relates to the field of transplanters, and more particularly to a mini crop transplanter. Background Technology

[0002] With the advancement of science and technology, agricultural planting is becoming increasingly mechanized and technologically advanced, with most planting processes now relying on machinery to replace manual labor. However, existing crop transplanters suffer from poor structural design, leading to uncoordinated lifting and seedling insertion actions. This can cause seedling displacement during transplanting, reducing efficiency. The inventor has been dedicated to developing transplanters, such as CN217850109U and CN220965582U. However, both of these models use a single duckbill for seedling insertion, resulting in low efficiency. Therefore, the applicant has been considering improvements to the transplanter.

The drive mechanism 2 is mounted on the main frame 11. A lifting bracket 12, perpendicular to the main frame 11, is located at the head of the main frame 11. A first rotating shaft 121, arranged along the height direction of the lifting bracket 12, is mounted on the lifting bracket 12 and can rotate rotatably along its own axis.

[0043] In this embodiment, the drive mechanism 2 includes a drive motor 21, a connecting shaft 24, a first drive gear 22, and a second drive gear 23 meshing with the first drive gear 22. A drive mounting plate 111 is provided on the main frame 11. The first drive gear 22 and the second drive gear 23 are mounted on the drive mounting plate 111.

The lifting guide rods 122 are respectively located on both sides of the first rotating shaft 121. The lifting moving frame 15 is provided with a plurality of rollers 151 for sliding on the lifting guide rods 122. The lifting moving frame 15 is slidably connected to the lifting guide rods 122 through the rollers 151, thereby further stabilizing the lifting movement of the lifting moving frame 15.

[0046] Furthermore, the rotating rod assembly includes a rotating rod cam 411, a rotating rod bearing 412, a rotating rod swing arm 413, a rotating rod joint rod 414, and a rotating rod connector 415. The rotating rod swing arm 413 has a rotating shaft connecting hole 4131 in the middle, and a rotating shaft mounting hole 113 on one side of the main frame 11. The rotating shaft connecting hole 4131 and the rotating shaft mounting hole 113 are connected by a connecting rod, allowing the rotating rod swing arm 413 to be rotatably mounted on the main frame 11. The rotating rod cam 411 is mounted and connected to the connecting shaft 24. The rotating rod bearing 412 is located at one end of the rotating rod swing arm 413 and is in contact with the rotating rod cam 411. The other end of the rotating rod swing arm 413 is rotatably connected to one end of the rotating rod joint rod 414. The other end of the rotating rod joint rod 414 is connected to the rotating rod connector 415, which is sleeved on the first rotating shaft 121.

[0047] The opening and closing assembly includes an opening and closing connector 421, an opening and closing joint rod 422, an opening and closing lever 423, an opening and closing sliding strip 424, and several opening and closing connecting rods 425. The lifting and moving frame 15 is provided with a lever mounting post 153, and the middle part of the opening and closing lever 423 is rotatably connected to the lever mounting post 153. The opening and closing connector 421 is sleeved on the first rotating shaft 121 and is rotatably connected to the opening and closing joint rod 422. The other end of the opening and closing joint rod 422 is rotatably connected to the opening and closing lever 423. The opening and closing sliding strip 424 is installed on the lifting and moving frame 15, and an opening and closing connecting block 426 is provided on the back of the sliding strip 424. The lifting and moving frame 15 is provided with a waist-shaped hole 152, and the opening and closing connecting block 426 passes through the waist-shaped hole 152 and connects to the other end of the opening and closing lever 423. Furthermore, the front of the opening and closing sliding strip 424 is provided with a plurality of opening and closing mounting holes 4241, and the opening and closing connecting rod 425 is installed in the opening and closing mounting holes 4241. Each of the opening and closing connecting rods 425 is connected to the duckbill movable block 51 of the duckbill assembly 5. Users can install one or more duckbill assemblies 5 according to actual needs, thereby meeting different production requirements.

[0048] In its initial state, the lifting and moving frame 15 is located at the top of the first rotating shaft 121. When the drive mechanism 2 is activated, the second drive gear 23 causes the rotating cam 411 and the adjustable crank 31 to rotate synchronously via the connecting shaft 24. When the adjustable crank 31 rotates, the lifting swing arm 33 moves like a crank rocker arm via the first lifting joint rod 32. The lifting swing arm 33 drives the second lifting joint rod 34 to make the lifting and moving frame 15 move up and down along the first rotating shaft 121. After the adjustable crank 31 rotates one revolution, the lifting and moving frame 15 will return to the top of the first rotating shaft 121, restoring its initial state.

[0049] As the adjustable crank 31 rotates, the rotating cam 411 also rotates synchronously, and the protrusion 4111 and the base circle 4112 of the rotating cam 411 alternately push the rotating bearing 412.

[0050] When the lifting and moving frame 15 descends, the rotating rod bearing 412 contacts and connects with the base circle portion 4112. At this time, the rotating rod swing arm 413 pushes the rotating rod connector 415 through the rotating rod joint rod 414, causing the first rotating shaft 121 to rotate clockwise by a certain angle along its own axis. While the first rotating shaft 121 rotates, the opening and closing connector 421 will rotate synchronously. The opening and closing connector 421 will push the opening and closing lever 423 to swing clockwise through the opening and closing joint rod 422. The opening and closing lever 423 drives the opening and closing sliding strip 424 to move laterally in the opposite direction through the opening and closing connecting block 426, so that the opening and closing connecting rod 425 controls the duckbill movable block 51 of the duckbill assembly 5 to close. At this time, the duckbill assembly 5 can carry the seedlings and descend to break the soil and open the hole.

[0051] When the lifting and moving frame 15 rises, the protrusion 4111 pushes the rotating rod bearing 412, and the rotating rod swing arm 413 pulls the rotating rod connector 415 through the rotating rod joint rod 414, causing the first rotating shaft 121 to rotate counterclockwise by a certain angle along its own axis. At the same time as the first rotating shaft 121 rotates, the opening and closing connector 421 will rotate synchronously. The opening and closing connector 421 will pull the opening and closing lever 423 to swing counterclockwise through the opening and closing joint rod 422. The other end of the opening and closing lever 423 will drive the opening and closing sliding strip 424 to move laterally through the opening and closing connecting block 426, so that the opening and closing connecting rod 425 controls the duckbill movable blocks 51 of multiple duckbill assemblies 5 to open. At this time, the duckbill assembly 5 opens, allowing the seedling to be placed in the soil hole and rise away from the ground. The lifting and moving frame 15 returns to the top of the first rotating shaft 121 and returns to the initial state, thus completing the seedling transplanting operation.

[0052] In this embodiment, the mini crop transplanter also includes a square tube frame 13, two walking connecting frames 14, and two sets of walking mechanisms 6. The square tube frame 13 extends laterally through both sides of the main frame 11, and the two walking connecting frames 14 are respectively disposed at both ends of the square tube frame 13. The walking mechanism 6 includes a walking support 61, and the walking connecting frames 14 are liftably mounted on the walking support 61. The user can adjust the spacing between the two walking connecting frames 14 according to the actual situation, so that the two sets of walking mechanisms 6 can meet the transplanting needs of different terrains. The walking mechanism 6 is a four-wheel drive structure.

[0053] Furthermore, the walking support 61 is provided with a plurality of vertically distributed height adjustment holes 611, and the walking connecting frame 14 is provided with height connection holes 141 for connecting with the height adjustment holes 611. When facing different terrains, the user can align the height adjustment hole 611 with the height connection hole 141 of the corresponding height setting and connect them with fasteners to fix the walking connecting frame 14 at the corresponding height, thereby adjusting the height of the main frame 11 from the ground and avoiding the problem of the main frame 11 being too low or too high, effectively adapting to different terrain environments.

[0054] In this embodiment, the main frame 11 is also provided with a generator assembly 7 and a battery assembly 8. The battery assembly 8 is electrically connected to the generator assembly 7, and the generator assembly 7 is electrically connected to the drive mechanism 2.

[0055] In this embodiment, the top of the lifting support 12 is provided with a seedling tray assembly 9. The seedling tray assembly 9 includes a multi-layer seedling tray frame 91 and several seedling trays 92, with the seedling trays 92 placed on the multi-layer seedling tray frame 91. The multi-layer seedling tray frame 91 includes a support frame and shelf units. The support frame is provided with several adjustment holes, and the shelf units are fixed to the support frame through the adjustment holes. The spacing between the shelf units can also be adjusted through the adjustment holes to facilitate lighting and ventilation for each layer.

[0056] This utility model relates to a mini crop transplanter with a simple structure. The spacing between the walking mechanisms 6 and the height of the main frame 11 are adjustable, which is convenient for operation in different terrain environments. In this utility model, the driving mechanism 2 can simultaneously drive the lifting mechanism 3 and the opening and closing mechanism 4, so that the duckbill assembly 5 opens and closes synchronously during the lifting process to carry out the transplanting operation, making the transplanting process smoother, reducing the difficulty of transplanting, and improving the efficiency of transplanting operation.

[0057] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
