Description

Technical Field

[0001] This utility model relates to a frame-separated pineapple seedling transplanting device, belonging to the field of agricultural machinery technology. Background Technology

[0002] Pineapple seedling transplanting is a crucial step in pineapple production, and mechanized transplanting is essential for improving industry efficiency. However, existing automatic pineapple transplanters suffer from significant technical bottlenecks in their planting mechanisms during practical applications, specifically: In mechanized pineapple cultivation, existing planters mostly employ chain clamps or duckbill-type fixed-stroke structures. The core problem with these is the difficulty in adaptively adjusting the clamping force and opening / closing time according to the different sizes of pineapple seedlings. Furthermore, due to the variations in seedling size, the planter cannot adapt to the release conditions required by different seedlings when releasing them in a very short time. This makes it difficult for the planter to completely separate from the seedling after release, resulting in some seedlings being re-clamped and pulled back, failing to fall into the pre-set planting furrow or hole, causing missed planting. This necessitates frequent machine stops for manual replanting, significantly reducing the efficiency advantage of mechanized operations and preventing continuous, high-efficiency operation. In summary, the problems of "seedling clamping" and "seedling re-pulling" are the core technical obstacles restricting the widespread application of pineapple transplanters. They lead to a series of chain reactions, including low transplant survival rates, high missed planting rates, unstable operating efficiency, and increased costs for manual replanting. Therefore, there is an urgent need for a new type of pineapple seedling transplanting mechanism that can ensure adaptive clamping and complete release to fundamentally improve the quality and efficiency of mechanized pineapple transplanting.

The planter includes several planting frames, two supports symmetrically fixed to the top of the frame, a rotating assembly installed between the two supports, and an eccentric assembly located on one side of the rotating assembly and rotatably connected to the support on the same side. The rotating assembly includes a rotating body and several rotating shafts. Each rotating shaft is rotatably connected to the rotating body and the several rotating shafts are distributed circumferentially along the rotating body. During the rotation of the rotating assembly, the several rotating shafts rotate at the same speed through the eccentric assembly. At least one planting frame is installed on each rotating shaft. The planting frame includes a frame body and a frame door. One side of the frame body is open and fastened to one side of the frame door. The top of the frame body has a seedling inlet. The frame door is arranged vertically and its upper part is fixedly connected to the rotating shaft. The upper part of the frame body is rotatably connected to the rotating shaft. An auxiliary plate is vertically extended and fixedly installed at the bottom of the frame body.

The trenchers and soil covering devices are arranged in a one-to-one correspondence and are located in front of and behind the planter, respectively. Several compaction wheels are located behind several soil covering devices. The number of planting frames on each rotating shaft is the same as the number of trenchers and are arranged in a front-to-back correspondence.

[0005] Furthermore, the eccentric assembly includes an eccentric fixing plate, an eccentric disk frame, at least two pulleys, and several eccentric connecting shafts. The eccentric fixing plate is fixedly connected to the bracket. The eccentric disk frame has a central through hole. The pulleys are mounted on the eccentric fixing plate, and the grooves on the pulleys are set to fit the inner wall of the central through hole. The number of eccentric connecting shafts is the same as that of the rotating shaft. One end of each eccentric connecting shaft is fixedly connected to the rotating shaft, and the other end is rotatably mounted on the eccentric disk frame. The rotation axis of the eccentric disk frame is offset from the rotation axis of the rotating assembly.

[0006] Furthermore, the eccentric connecting shaft has a Z-shaped structure.

[0007] Furthermore, the frame includes a frame body and a connector, wherein the connector is rotatably mounted on a rotating shaft and two sets of limiting components are arranged vertically and parallel on the connector, and the upper end of the frame body is placed on the connector and slides up and down along the two sets of limiting components.

[0008] Furthermore, the bottom of the frame is angled downwards, with its lower end being the end closest to the frame door.

[0015] In addition, this utility model achieves seedling placement by opening the frame and frame door through the auxiliary plate touching the ground. The size of the pineapple seedling has no effect on the seedling placement speed, and thus will not affect the seedling release time, effectively avoiding the problem of seedlings being brought back. Furthermore, by controlling the planter to rotate at a uniform speed through the drive component, one or multiple planting frames can be arranged on the same rotating shaft, ensuring that the seedling placement action of the planting frames on the same rotating shaft is carried out synchronously, resulting in higher mechanization efficiency and enabling continuous and efficient operation.

[0018] Specific implementation method one: Combining Figures 1-15 This description aims to clearly and completely describe the technical solutions in this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A frame-separated pineapple seedling transplanting device includes a frame 1, a walking assembly 2 installed below the frame 1, a seedling box 3, a planter 4, and a drive assembly 5 installed above the frame 1. The front end of the frame 1 is connected to a traction device, the seedling box 3 is located behind the planter 4, and the drive assembly 5 controls the movement of the planter 4. The planter 4 includes several planting frames 41, two supports 42 symmetrically fixed to the top of the frame 1, a rotating assembly 43 installed between the two supports 42, and an eccentric assembly 44 located on one side of the rotating assembly 43 and rotatably connected to the support 42 on the same side. The rotating assembly 43 includes a rotating body and several rotating shafts 431. Each rotating shaft 431 is rotatably connected to the rotating body, and the several rotating shafts 431 are distributed circumferentially along the rotating body. During the rotation of the rotating assembly 43, the eccentric assembly 44... 4. Several rotating shafts 431 rotate at the same speed. Each rotating shaft 431 is equipped with at least one planting frame 41. The planting frame 41 includes a frame body 411 and a frame door 412. The frame body 411 is open on one side and fastened to one side of the frame door 412. The top of the frame body 411 has a seedling inlet. The frame door 412 is arranged vertically and its upper part is fixedly connected to the rotating shaft 431. The upper part of the frame body 411 is rotatably connected to the rotating shaft 431. The bottom end of the frame body 411 extends vertically and is fixedly equipped with an auxiliary plate 413. Several trenchers 6, several soil covering devices 7 and several pressing wheels 8 are installed under the frame 1. The trenchers 6 and soil covering devices 7 are arranged in a one-to-one correspondence and are located in front of and behind the planter 4, respectively. The pressing wheels 8 are located behind the soil covering devices 7. The number of planting frames 41 on each rotating shaft 431 is the same as the number of trenchers 6 and are arranged in a front-to-back correspondence.

[0020] The traction device can be agricultural machinery such as tractors.

[0021] The front end of the frame 1 is provided with a suspension point 9 for connecting to the traction equipment.

[0022] Depending on actual needs, the walking component 2 can provide forward propulsion, auxiliary support, and / or auxiliary walking for the frame 1 and the seedling box 3, planter 4, etc. above it.

[0023] The seedling box 3 is used to store pineapple seedlings.

[0024] The drive component 5 can be any structure that can drive the planter 4 to rotate.

[0025] By rotatably connecting each shaft 431 to the rotating body, the eccentric component 44 can smoothly drive the shaft 431 to rotate at the same speed.

[0026] Several rotating shafts 431 are preferably evenly distributed along the circumference of the rotating body, which can ensure that the pineapple seedlings are spaced evenly.

[0027] The seedling inlet at the top of frame 411 is used by staff to put pineapple seedlings into frame 411. The larger the seedling inlet, the easier it is to put the seedlings in.

[0028] The auxiliary board 413 can be a flat plate or a balustrade structure, as long as it can block the pineapple seedlings inside the frame 411 before and after transplanting.

[0029] The number of rotating shafts 431 is preferably five, and the number of planting frames 41 installed on each rotating shaft 431 is preferably four.

[0030] During operation, the traction device propels the pineapple seedling transplanting device forward. First, the furrow opener 6 opens furrows in the soil, while simultaneously the drive assembly 5 controls the planter 4 to rotate in the same direction as the forward movement (towards...). Figure 4 Taking the direction shown as an example, the left side of the diagram is the front, and the right side is the rear. The pineapple seedling transplanting device moves forward, and the planter 4 rotates counterclockwise. During the process, staff placed the pineapple seedlings from seedling box 3 vertically into frame 411. During the rotation of the rotating component 43, the planting frame 41 remains perpendicular to the ground, and the pineapple seedlings remain vertical. When the auxiliary plate 413 at the bottom of the frame 411 is inserted vertically into the soil, the planting frame 41 moves in the opposite direction to the direction of travel, and the horizontal velocity is the same. Under the action of soil resistance, the frame 411 separates from the frame door 412 and opens to release the seedling. Under the action of gravity, the pineapple seedling slides out along the frame 411 and falls into the planting furrow that has been opened by the furrow opener 6.

[0031] As the moving and rotating components 43 move to the lowest point, the planting frame 41 is lifted, and the frame 411 begins to stand upright and enter the seedling support process. When the auxiliary plate 413 at the bottom of the frame 411 separates from the soil along the circumferential direction of the rotating components 43, the seedling support ends. At the same time, the soil covering device 7 backfills the soil on both sides of the planting trench, and the compaction wheel 8 compacts the soil on both sides of the pineapple seedling, completing one planting process.

[0032] The frame-separated pineapple seedling transplanting device of this utility model allows seedlings to be placed in the frame by opening the frame 411 and the frame door 412. The entire transplanting process does not involve clamping the pineapple seedlings, thus enabling frame-separated planting of pineapple seedlings.

[0033] In addition, this utility model achieves seedling placement by having the auxiliary plate 413 touch the ground to open the frame 411 and the frame door 412. The size of the pineapple seedling has no effect on the seedling placement speed, and therefore will not affect the seedling release time, effectively avoiding the problem of seedlings being brought back. Furthermore, the planter 4 is controlled to rotate at a uniform speed by the drive component 5. One or multiple planting frames 41 are arranged on the same rotating shaft 431, which can ensure that the seedling placement action of the planting frames 41 on the same rotating shaft 431 is synchronized, resulting in higher mechanization efficiency and enabling continuous and efficient operation.

[0034] The eccentric assembly 44 includes an eccentric fixing plate 441, an eccentric disk frame 442, at least two pulleys 443, and several eccentric connecting shafts 444. The eccentric fixing plate 441 is fixedly connected to the bracket 42. The eccentric disk frame 442 has a central through hole. The pulleys 443 are mounted on the eccentric fixing plate 441, and their grooves fit against the inner wall of the central through hole. The number of eccentric connecting shafts 444 is the same as the number of rotating shafts 431. One end of each eccentric connecting shaft 444 is fixedly connected to the rotating shaft 431, and the other end is rotatably mounted on the eccentric disk frame 442. The rotation axis of the eccentric disk frame 442 is offset from the rotation axis of the rotating assembly 43. This design allows for eccentric rotation between the eccentric disk frame 442 and the rotating disk frame 433 by offsetting the rotation axis of the eccentric disk frame 442 from the rotation axis of the rotating assembly 43. During the rotation of the rotating component 43, the rotating shaft 431 moves synchronously. As the rotating shaft 431 moves, the eccentric plate frame 442 causes the rotating shaft 431 to rotate at the same speed through the eccentric connecting shaft 444, thereby ensuring that the planting frame 41 always moves perpendicular to the ground in its natural state. The natural state is the state in which the planting frame 41 is not disturbed by other structures (such as the ground). The eccentric plate frame 442 can be made to rotate with the rotating component 43 through the pulleys 443. The number of pulleys 443 is preferably three and they are evenly distributed around the circumference to further ensure smooth and reliable rotation.

[0035] The eccentric disc frame 442 preferably includes an eccentric ring 445 and a plurality of connecting plates 446 fixed circumferentially along the eccentric ring 445. The number of connecting plates 446 in each eccentric disc frame 442 is the same as the number of rotating shafts 431 and they are arranged in a one-to-one correspondence. A first support beam 447 is fixed between every two adjacent connecting plates 446. One end of the eccentric connecting shaft 444 is rotatably connected to the connecting plate 446. The connecting plate 446 is preferably a channel steel.

[0036] The eccentric connecting shaft 444 has a Z-shaped structure. This design facilitates the connection between the eccentric connecting shaft 444, the rotating shaft 431, and the eccentric disc frame 442.

[0037] The frame 411 includes a frame body 414 and a connector 415. The connector 415 is rotatably mounted on a rotating shaft 431, and two sets of limiting components 416 are arranged vertically and parallel on the connector 415. The upper end of the frame body 414 rests on the connector 415 and slides up and down along the two sets of limiting components 416. This design enables a rotatable connection between the frame 411 and the rotating shaft 431 through the connector 415. When the auxiliary plate 413 contacts the soil, the frame body 414 rotates relative to the rotating shaft 431 and moves up and down along the limiting components 416 through the connector 415, preventing the auxiliary plate 413 from sinking deeper and deeper into the soil during the rotation of the rotating component 43.

[0038] The bottom of the frame 411 is inclined downwards, with its lower end being the end closest to the frame door 412. This design makes it easier for the pineapple seedling to fall when the frame 411 is separated from the frame door 412 and opened during transplanting.

[0039] The bottom of the auxiliary plate 413 is set lower than the frame door 412. This design ensures that the auxiliary plate 413 is not blocked by the frame door 412 when it comes into contact with the soil, further ensuring the efficiency of seedling placement and planting.

[0040] The bottom of the auxiliary plate 413 is pointed. This design facilitates the insertion of the auxiliary plate into the ground. The rotating body includes a drive shaft 432 and two turntable frames 433 coaxially fixed at both ends of the drive shaft 432. The two ends of the rotating shaft 431 are rotatably connected to the two turntable frames 433. Preferably, each turntable frame 433 includes a positioning plate 434 and several positioning plates 435 fixed circumferentially along the positioning plate 434. The number of positioning plates 435 in each turntable frame 433 is the same as the number of rotating shafts 431 and they are arranged in a one-to-one correspondence. A second support beam 436 is fixed between every two adjacent positioning plates 435, and the two ends of the rotating shaft 431 are rotatably connected to the corresponding positioning plates 435 on both sides. By setting the second support beam 436, the structural stability of the turntable frame 433 is further improved, while significantly reducing its weight. The positioning plates 435 are preferably of channel steel structure.

[0041] The drive assembly 5 includes a drive motor 51 and a chain drive assembly 52. ​​The drive motor 51 is fixedly mounted on the frame 1, and drives the rotating main body to move via the chain drive assembly 52. ​​In this design, the driving sprocket of the chain drive assembly 52 is fixedly connected to the output shaft of the drive motor 51, and the driven sprocket of the chain drive assembly 52 is coaxially fixedly connected to the rotating main body. The chain drive assembly 52 can also be replaced with a belt drive assembly.

[0042] A seat 10 is installed inside the seedling box 3. This design facilitates the seedling placement operation for staff during work and reduces workload. The number of seats 10 is determined by the number of planting frames 41 arranged laterally. For example, when four planting frames 41 are arranged axially along the pivot 431, two seats 10 can be arranged side by side, with each seat 10 corresponding to two planting frames 41. This allows one staff member to place seedlings into two planting frames 41 simultaneously, effectively reducing labor costs.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
