[0001] This invention relates to the field of rice transplanter technology, specifically to an automatic seedling-changing paddy field painting rice transplanter. Background Technology

[0002] In the wave of agricultural tourism integration, the precision operation capabilities of rice transplanters are becoming a core technological support for the implementation of distinctive experience projects such as rice paddy art and digital farmland. As the scale of rice paddy art creation continues to expand, how to efficiently and accurately complete the differentiated transplanting of multi-colored seedlings is gradually becoming a key issue that agricultural tourism growers urgently need to solve.

[0003] However, traditional manual rice transplanting is not only inefficient and unsuitable for large-scale rice paddy art planting, but also prone to jagged edges due to human error, severely affecting the visual presentation. Therefore, we have developed a new type of automatic seedling-changing rice paddy art transplanter. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-10 The present invention provides a technical solution:

[0032] An automatic seedling-changing rice transplanter includes a transplanting assembly 11 mounted on a horizontal frame, with a seedling insertion point installed on the front side of the frame. A changing wheel 2, for rotating seedling support brackets 3, is mounted on the top of the horizontal frame. The seedling support brackets 3 are evenly distributed on the top of the changing wheel 2, and seedling placement plates 4 for placing seedling trays are slidably connected to each seedling support bracket 3. A seedling support frame 5 is provided between the changing wheel 2 and the transplanting assembly 11. Rotation of the changing wheel 2 causes one of the seedling support brackets 3 to engage with the seedling support frame 5, allowing switching between multiple seedling support brackets 3. A conveying assembly 6 is provided on the seedling support frame 5 for transporting seedling trays. The conveying assembly 6 transports the seedling trays from the seedling support brackets 3 engaged with the seedling support frame 5 downwards to the transplanting assembly 11, and conversely, it transports the seedling trays from the transplanting assembly 11 back to the seedling support brackets 3 engaged with the seedling support frame 5.

[0033] The seedling support frame 5 includes a longitudinal frame 51 and a transverse frame 52. When the transverse frame 52 moves horizontally on the transverse frame, it drives the longitudinal frame 51 to move horizontally as well, thereby driving the seedling trays to move horizontally. The longitudinal frame 51 can move longitudinally at an angle on the transverse frame 52. When the rice transplanter encounters deep water during its journey, the longitudinal frame 51 can be lifted upwards. The angle of inclination is designed to prevent the seedling trays from tipping over vertically into the paddy field during transport. The conveying component 6 is mounted on the longitudinal frame 51. A seedling tray support tray 8, adapted to the transplanting component 11, can also be mounted on the front side of the transverse frame. The seedling tray support tray 8 has an opening corresponding to the transplanting component 11 to avoid obstructing the transplanting action. The seedling tray support tray 8 is located below the longitudinal frame 51, and the seedling trays are transported from the seedling preparation plate 4 to the seedling tray support tray 8 via the conveying component 6. The seedling tray support tray 8 is tilted inwards to reduce the possibility of the seedling trays tipping forward.

[0034] The transverse frame 52 can be moved on the transverse frame via a transverse adjustment drive group 7. The transverse adjustment drive group 7 includes a first drive wheel 71 and a first rack 72. The first drive wheel 71, which is connected to a motor, is connected to the transverse frame. The first rack 72 is fixed on the transverse frame 52, and the first drive wheel 71 and the first rack 72 are meshed together. A transverse rail is provided on the transverse frame, and a sliding groove is fixedly connected to the bottom of the transverse frame 52, which is slidably connected to the transverse rail on the vehicle body frame 1.

[0035] The transverse frame 52 is provided with a sliding groove, and the lower part of the longitudinal frame 51 is provided with a support frame slide rail 55 that is slidably connected to the sliding groove. Then, a longitudinal drive group for driving the longitudinal frame 51 to move is provided between the longitudinal frame 51 and the transverse frame 52. The longitudinal drive group includes a second drive wheel 53 and a second rack 54. The second drive wheel 53, which is connected to a motor, is connected to the transverse frame 52, and the second rack 54 is fixedly connected to the longitudinal frame 51. The second drive wheel 53 and the second rack 54 are meshed together.

[0036] The conveying assembly 6 includes a conveying track 64 fixed to the inner wall of the longitudinal frame 51. A support plate 61 for carrying seedling trays is slidably connected to the outer side of the conveying track 64. A conveying drive assembly 65 is provided on the longitudinal frame 51 to drive the support plate 61 to move along the conveying track 64. The conveying drive assembly 65 includes a third driving wheel and a driven wheel respectively located at the upper and lower ends of the longitudinal frame 51. A traction belt 66 is sleeved on the outer wall of the third driving wheel and the driven wheel. The traction belt 66 is fixed to the support plate 61. This allows the third driving wheel to drive the support plate 61 to rise and fall via the traction belt 66. A pallet connecting rod 63 is connected to the bottom of the support plate 61. A conveying tray 62 is connected to the bottom of the pallet connecting rod 63. The conveying tray 62 is connected to a sliding sleeve via a hinge. The sliding sleeve can slide on the outer wall of the conveying track 64. A height limiting block is also provided at the bottom of the conveying track 64 to block the sliding sleeve. The pallet connecting rod 63 is used to drive the transport pallet 62 to rotate around the sliding sleeve and adjust the angle between the transport pallet 62 and the support plate 61. When the transport pallet 62 needs to lift the seedling tray, the angle between the transport pallet 62 and the support plate 61 is ≤90°. During the rice transplanting operation, the angle between the transport pallet 62 and the support plate 61 is 180°.

[0037] The seedling support 3 includes a seedling base frame 31, on which four seedling plate column slides 32 are provided. The seedling placement plate 4 slides along the seedling plate column slides 32. Four holes are opened on the surface of the seedling plate 41 to match the seedling plate column slides 32.

[0038] The seedling placement plate 4 includes a seedling plate 41, which is sleeved on the outside of the seedling plate column slide 32. A seedling tray drive assembly is provided between the seedling plate 41 and the seedling plate column slide 32 to drive the seedling plate 41 to move along the seedling plate column slide 32. A collar is sleeved on the seedling plate column slide 32, and a roller that contacts the seedling plate column slide 32 is rotatably connected to the inner wall of the collar. A motor that drives the roller to rotate is fixed to the outer wall of the collar. A seedling tray support plate 44 for supporting the seedling tray is fixed to the bottom of the seedling plate 41.

[0039] The top surface of the preparation plate 41 is provided with two protruding ribs 43, which create a gap between the preparation plate 41 and the seedling tray. When the supporting plate 61 moves upward, it can be inserted into the gap.

[0040] Each of the seedling placement plates 4 is equipped with a positioning sensor and a weighing sensor. Different colored seedlings are placed on designated seedling placement plates 4. A specific positioning sensor is set for each seedling placement plate 4 to identify its number, thus accurately determining which seedling color is on which plate. Each seedling placement plate 4 is also equipped with a weighing sensor to detect whether a seedling tray or the remaining amount of seedlings is on it.

[0041] The front wheels of the rice transplanter are connected to the transverse frame via an independent suspension front steering wheel assembly 9, which is also equipped with a steering drive.

[0042] The front steering wheel assembly 9 consists of a servo motor, rubber wheels, spherical bearings, connecting plates, shock absorbers, slider rails, and block-shaped seated bearings. The seated bearings are connected to the upper connecting plate and the vehicle frame 1 via shafts through fixing holes on both sides, and can rotate around the shafts. The middle part of the vehicle frame 1 is connected to the vehicle body frame via shock absorbers. The upper part of the seated bearing is connected to the spherical bearing via a rotating shaft, and the middle part is connected to the rubber wheels. The other end of the spherical bearing is connected to the slider rail fixed between the two connecting plates. The servo motor is located inside the front of the chassis and connected to the lower base plate. The servo motor has a rotating rod, which is connected to either the left or right spherical bearing.

[0043] The rear wheels of the rice transplanter are connected to the transverse frame via an independently suspended rear drive wheel set 10, which is equipped with a drive mechanism to propel the rice transplanter forward.

[0044] The rear drive wheel assembly 10 consists of a drive motor, a connecting plate, a block-shaped seated bearing, a shock absorber, and a universal joint. Its structure is compatible with the connection method of the front steering wheel assembly 9. The seated bearing is connected to the upper connecting plate and the vehicle frame 1 respectively through the fixing holes on both sides by a shaft. The outer side of the middle part is connected to the rubber wheel, and the inner side of the middle part is connected to the universal joint. The other end of the universal joint is connected to the motor. The motor is fixed to the inner side of the rear of the chassis and connected to the lower floor plate. The middle part of the vehicle frame 1 is connected to the vehicle body frame through the shock absorber.

[0045] Working principle:

[0046] The seedling trays containing different colored seedlings are placed on the preparation plate 41. The rice transplanter travels to the rice transplanting area, and the position sensor transmits the position to the operation center. The rice transplanter then starts working according to the command from the operation center.

[0047] First, by changing the wheel 2, the seedling tray containing the seedlings to be planted is moved above the seedling support frame 5. The third drive wheel drives the support plate 61 upward along the conveyor track 64 via the traction belt 66, and the support plate 61 is inserted into the gap between the seedling tray and the preparation plate 41. At the same time, the support plate 61 drives the pallet connecting rod 63 upward, and the pallet connecting rod 63 drives the transport tray 62 to flip. When the transport tray 62 is flipped into place, the pallet connecting rod 63 drives the transport tray 62 to move upward along the conveyor track 64 with the support plate 61. When the transport tray 62 approaches the preparation plate 44, the preparation plate drive 42 is activated, driving the preparation plate 41 to slide downward along the preparation plate column slide. The seedling tray will first fall onto the support plate 61 until the preparation plate 44 no longer obstructs the seedling tray, and the seedling tray slides down onto the transport tray 62.

[0048] Then, the third drive wheel drives the support plate 61 to move downward along the conveyor track 64 via the traction belt 66. When the transport tray 62 moves to the bottom of the conveyor track 64, the sliding sleeve supporting the transport tray 62 is blocked. At this time, the support plate 61 continues to drive the tray connecting rod 63 to move downward, and the tray connecting rod 63 pushes the transport tray 62 to flip downward. The seedling tray loses the support of the transport tray 62 and falls onto the seedling tray support tray 8, and the transplanting assembly 11 begins to work.

[0049] Finally, the horizontal adjustment drive group 7 drives the horizontal frame 52 to move laterally, which in turn drives the vertical frame 51 to move laterally. The vertical frame 51 drives the bearing plate 61 to move laterally, and the bearing plate 61 drives the seedling tray to move laterally on the seedling tray bearing tray 8.

[0050] When changing seedling trays, the same procedure applies: return the seedling tray and retrieve the new one.
