Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice transplanter technology, specifically to a rice transplanter turning platform control device. Background Technology
[0002] A rice transplanter is an agricultural machine used to plant rice seedlings into paddy fields. During planting, a mechanical claw first removes several rice seedlings from a seedbed and plants them into the soil. To maintain a right angle between the seedbed and the ground, the front end of the claw must move in an elliptical curve. The movement is accomplished by a planetary mechanism using rotary or variable gears, while a forward engine drives these moving parts. The transplanter must have non-slip wheels and a floating design to move on the soil. If planting in rows, seedlings are taken from specific seed boxes and planted mechanically.
[0003] A common rice transplanter, for example, patent CN218006982U proposes a rice transplanter with a lateral seedling lowering mechanism connected to the upper end of the frame; and a transplanting drive mechanism connected to the frame and located on one side of the lateral seedling lowering mechanism.
[0004] Currently, small rice transplanters on the market have the problem of difficulty turning, which can easily cause them to bump into newly planted rice seedlings and affect the planting process. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a turning control device for a rice transplanter to solve the problems mentioned in the background. This utility model has a novel structure. It controls the rice transplanting device and the placement plate to rise and lift them off the planting ground through a lifting component, thereby avoiding contact with the seedlings during the turning process. The linkage component merges the protective frame while the placement plate is raised to protect the seedlings pre-stored on the placement plate, thereby preventing the seedlings from falling off during the lifting and turning process.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a turning platform control device for a rice transplanter, comprising a vehicle body, a rice transplanting device at the rear end of the vehicle body, a placement plate on the top of the rice transplanting device, a placement groove on the surface of the placement plate, protective frames rotatably mounted on both sides of the placement plate via a rotating shaft, the two protective frames being able to be combined into a single unit enclosing the front end of the placement plate, a lifting assembly at the rear end of the vehicle body, the lifting assembly comprising a connecting layer, electric push rods fixedly mounted on both sides of the connecting layer, the extended ends of the electric push rods being connected to the rice transplanting device, a linkage assembly on both sides of the top of the connecting layer, the linkage assembly comprising gears, a shaft connected at the top of the rotatable connection between the protective frame and the placement plate, and a gear sleeved on the top of the shaft of the protective frame, a toothed plate meshing with one side of the gear.
[0007] Furthermore, the lifting assembly also includes a slide rail frame, the top of the rice transplanting device is fixed with the slide rail frame, the placement plate is fixed on the slide rail frame, the connecting layer slides along the inside of the slide rail frame, and both ends of the electric push rod are fixedly connected to the slide rail frame.
[0008] Furthermore, the linkage component also includes an inclined slide rail. An inclined slide rail is provided at the top of the connecting layer corresponding to the position of the toothed plate, and a slider is slidably connected inside the inclined slide rail. The outer surface of the slider is rotatably connected to one end of the toothed plate through a rotating shaft.
[0009] Furthermore, a connecting frame is fixed to the top of the connecting layer, and the top ends of the connecting frame are fixedly connected to the inclined slide rail.
[0010] Furthermore, the inclined slide rail has a T-shaped groove inside, and the slider is a T-shaped block.
[0011] Furthermore, limit frames are fixed on both sides of the placement plate corresponding to the positions of the toothed plates, and the toothed plates slide along the top of the limit frames.
[0012] Furthermore, a controller is installed at the top center of the connection layer.
[0013] Furthermore, the inner wall of the protective frame is provided with an extrusion soft layer.
[0014] The beneficial effects of this utility model are:
[0015] 1. The inner wall compression soft layer of the protective frame of this utility model can protect the seedlings stacked on the placement board. After the protective frame is closed, the compression soft layer squeezes the front of the placement board to prevent the seedlings from falling out of the placement groove of the placement board.
[0016] 2. When the transplanting device and the placement plate descend, the slider side of the toothed plate slides downward along the inclined slide rail. Due to the inclined setting of the inclined slide rail and the interlocking action between the T-groove inside the inclined slide rail and the slider, the toothed plate is pulled to move. The toothed plate meshes with the gear, causing the protective frame to rotate 90 degrees and open, exposing the placement plate, which facilitates the continued transplanting of rice seedlings and the filling of new seedlings on the placement plate. Similarly, when the transplanting device and the placement plate move upward, the toothed plate meshes with the gear in the opposite direction under the guidance of the slider and the limiting frame. The gear drives the protective frame to rotate and merge, wrapping around the front end of the placement plate.
[0017] 3. This utility model uses an electric push rod to drive the slide rail frame to slide up and down along the connecting layer, adjusting the position and height of the rice transplanting device and the placement plate. The connecting layer is connected to the vehicle body, so its position will not change.
[0018] 4. Compared with the prior art, this utility model controls the rice transplanting device and the placement plate to rise and lift them off the planting ground through the lifting component, thereby avoiding contact with the seedlings during the turning process. The linkage component merges the protective frame at the same time as the placement plate is raised to protect the seedlings pre-stored on the placement plate, thereby preventing the seedlings from falling off during the lifting and turning process.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please see Figures 1 to 5This utility model provides a technical solution: a turning seedling platform control device for a rice transplanter, including a vehicle body 1. A rice transplanting device 2 is provided at the rear end of the vehicle body 1. A placement plate 3 is installed on the top of the rice transplanting device 2. A placement groove 31 is formed on the surface of the placement plate 3. Protective frames 4 are rotatably installed on both sides of the placement plate 3 via a rotating shaft. The two protective frames 4 can be combined into a whole to wrap around the front end of the placement plate 3. A lifting assembly 6 is provided at the rear end of the vehicle body 1. The lifting assembly 6 includes a connecting layer 61. Electric push rods 63 are fixedly installed on both sides of the connecting layer 61, and the extended ends of the electric push rods 63 are connected to the rice transplanting device 2. The top two... A linkage component 5 is provided on the side. The linkage component 5 includes a gear 53. A shaft is connected to the top of the rotational connection between the protective frame 4 and the placement plate 3. The top of the shaft of the protective frame 4 is sleeved with the gear 53. A toothed plate 54 is meshed with one side of the gear 53. The vehicle body 1, the transplanting device 2, and the placement plate 3 of this device are based on the same principle as existing small rice transplanters. When in use, the protective frame 4 is opened, and the seedlings are placed in the placement groove 31 of the placement plate 3. The transplanting device 2 is inserted into the ground. When the vehicle body 1 turns, the drive component and the linkage component 5 cooperate to raise the transplanting device 2 to a certain height. At the same time, the protective frame 4 closes to block the front end of the placement plate 3 to prevent the seedlings from falling.
[0027] In this embodiment, the lifting assembly 6 further includes a slide rail frame 62. The top of the rice transplanting device 2 is fixed with the slide rail frame 62, and the placement plate 3 is fixed on the slide rail frame 62. The connecting layer 61 slides along the inside of the slide rail frame 62, and both ends of the electric push rod 63 are fixedly connected to the slide rail frame 62. A controller 64 is installed at the top middle position of the connecting layer 61. The controller 64 transmits an electrical signal to the electric push rod 63, and the electric push rod 63 drives the slide rail frame 62 to slide up and down along the connecting layer 61, adjusting the position and height of the rice transplanting device 2 and the placement plate 3. The connecting layer 61 is connected to the vehicle body 1, so its position will not change. In this part of the technology, an angle sensor can be installed in the steering wheel of the vehicle body 1 to monitor the rotation angle of the steering wheel. When the rotation angle is too large, it is determined that a turn is in progress. At this time, the controller 64 drives the drive assembly to lift the rice transplanting device 2 and the placement plate 3 to avoid collision with the planted seedlings.
[0028] In this embodiment, the linkage component 5 further includes an inclined slide rail 52. An inclined slide rail 52 is provided at the top of the connecting layer 61 corresponding to the position of the toothed plate 54, and a slider 55 is slidably connected inside the inclined slide rail 52. The outer surface of the slider 55 is rotatably connected to one end of the toothed plate 54 via a rotating shaft. A connecting frame 51 is fixed at the top of the connecting layer 61, and the tops of both ends of the connecting frame 51 are fixedly connected to the inclined slide rail 52. The inclined slide rail 52 has a T-shaped groove inside, and the slider 55 is a T-shaped block. Limit frames 56 are fixed on both sides of the placement plate 3 corresponding to the positions of the toothed plate 54, and the toothed plate 54 slides along the top of the limit frames 56. In the rice transplanting device 2... When the placement plate 3 descends, the slider 55 of the toothed plate 54 slides downward along the inclined slide rail 52. Due to the inclined setting of the inclined slide rail 52 and the engagement between the T-slot inside the inclined slide rail 52 and the slider 55, the toothed plate 54 is pulled to move. The toothed plate 54 meshes with the gear 53, causing the protective frame 4 to rotate 90 degrees and open, exposing the placement plate 3, which facilitates the continued transplanting of rice seedlings and the filling of new seedlings on the placement plate 3. Similarly, when the transplanting device 2 and the placement plate 3 move upward, the toothed plate 54 meshes with the gear 53 in the opposite direction under the guidance of the slider 55 and the limiting frame 56. The gear 53 drives the protective frame 4 to rotate and merge, wrapping around the front end of the placement plate 3.
[0029] In this embodiment, the inner wall of the protective frame 4 is provided with a compression soft layer 41. The compression soft layer 41 on the inner wall of the protective frame 4 can protect the seedlings stacked on the placement plate 3. After the protective frame 4 is closed, the compression soft layer 41 compresses the front of the placement plate 3 to prevent the seedlings from falling out of the placement groove 31 of the placement plate 3.
[0030] In use, the protective frame 4 is opened, and seedlings are placed in the placement slot 31 of the placement plate 3. The seedlings are then inserted into the ground by the transplanting device 2. When the vehicle body 1 turns, the electric push rod 63 drives the slide rail frame 62 to slide up and down along the connecting layer 61, adjusting the position and height of the transplanting device 2 and the placement plate 3. When the transplanting device 2 and the placement plate 3 move upward, the toothed plate 54, guided by the slider 55 and the limiting frame 56, meshes with the gear 53 in the opposite direction. The gear 53 drives the protective frame 4 to rotate and merge, wrapping around the front end of the placement plate 3. The protective frame 4 blocks the front end of the placement plate 3 to prevent the seedlings from falling. When the transplanting device 2 and the placement plate 3 descend, the slider 55 of the toothed plate 54 slides down along the inclined slide rail 52. Due to the inclined setting of the inclined slide rail 52 and the engagement between the T-slot inside the inclined slide rail 52 and the slider 55, the toothed plate 54 is pulled to move. The toothed plate 54 meshes with the gear 53, causing the protective frame 4 to rotate 90 degrees and open, exposing the placement plate 3, which facilitates the continued transplanting and filling of new seedlings on the placement plate 3.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
