Description

Technical Field

[0001] The invention relates to a seedling transplanting device. Background Art

[0002] With the development of agricultural technology, the advantages of transplanting seedlings are very obvious, so it is more and more widely used in the planting industry, especially in large-scale agricultural planting, the advantages of transplanting seedlings through seedling transplanters are more prominent.

[0003] The current seedling transplanters are mainly used for smaller seedlings, and the posture requirements for smaller seedlings during transplanting are generally not high, and they can usually be placed in the soil.

[0004] Transplanting devices such as those disclosed in CN221429548U, CN111976A, CN106258121A, CN201571326U, CN2619468Y, and CN110612801A all place seedlings by means of a clamping duckbill provided with a fixed plate and a movable plate. When working, the duckbill is driven to rotate by the planter, and when reaching the bottom, the duckbill is inserted into the soil and the movable plate is opened, so that the seedlings placed inside are implanted into the soil, thereby completing the transplanting of the seedlings.

[0005] The clamping duckbill of the above-mentioned transplanting device releases the seedlings by setting a touch block on the moving plate and a trigger slide rail on the moving track of the moving plate. When the touch block touches the trigger slide rail, the moving plate opens to achieve the release of the seedlings.

[0006] The clamping duckbill of the above-mentioned transplanting device has the following main problems due to its structural design. First, the movable plate of the clamping duckbill opens and closes up and down, and the opening and closing degree is small. In particular, the fixed plate is a barrel-shaped body, which is only suitable for smaller seedlings. Slightly larger seedlings can easily be stuck by the barrel-shaped body, resulting in failure of seedling transplanting. Second, the posture of the seedlings is difficult to control during transplanting, and skewness is inevitable. Third, the time for keeping the movable plate of the clamping duckbill in the open state is affected by the trigger slide rail, especially the length of the trigger slide rail, resulting in poor operating stability, making the duckbill inflexible in opening and closing and prone to failure.

[0007] Therefore, a seedling transplanting device with high operating stability, more flexible duckbill opening and closing, and especially suitable for larger seedlings, has emerged. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a seedling transplanting device with high operating stability and more flexible duckbill opening and closing, which is particularly suitable for larger seedlings.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: comprising a frame, on which a seedling cup transmission mechanism (12) is provided, characterized in that a seedling cup clamping and dropping cup is provided on the seedling cup transmission mechanism (12), and the seedling cup clamping and dropping cup comprises a fixed plate (31), a first connecting shaft (33) and a second connecting shaft (34), a first movable plate (35) is provided on the fixed plate (31), the first movable plate (35) is hinged to the fixed plate (31) in a horizontal direction and is provided with a bump block (36), a state locking mechanism (37) is provided between the first movable plate (35) and the fixed plate (31), and the state locking mechanism (37) is provided with a state triggering mechanism (38).

[0010] Furthermore, the state locking mechanism (37) is a self-locking mechanism (39) linked to the first movable plate (35), and the state triggering mechanism (38) comprises a lever and a triggering end linked to the lever.

[0011] Furthermore, the self-locking mechanism (39) is preferably a ratchet and ratchet mechanism, the ratchet of the ratchet and ratchet mechanism is linked with the first movable plate (35), and the trigger end is a pawl.

[0012] Alternatively, the self-locking mechanism (39) is a locking tongue mechanism: it comprises a rotating wheel linked to the first movable plate (35), a convex tooth or a concave pit is provided on the rotating wheel, and the trigger end is a corresponding concave pit or convex tooth.

[0013] The seedling cup transmission mechanism (12) is a ring-shaped conveying chain, a disc-shaped rotating wheel or a star-shaped supporting frame, and a seedling cup posture stabilizing mechanism (13) is arranged in parallel with the seedling cup transmission mechanism (12). The seedling cup posture stabilizing mechanism (13) is a conveying chain, a disc-shaped rotating wheel or a star-shaped supporting frame with the same structure as the seedling cup transmission mechanism (12), and the seedling cup transmission mechanism (12) and the seedling cup posture stabilizing mechanism (13) are arranged on the frame in an eccentric manner up and down or front and back. The second connecting shaft (34) for clamping the seedling cup is connected to the seedling cup transmission mechanism (12), and the first connecting shaft (33) is connected to the seedling cup posture stabilizing mechanism (13) for clamping the seedling cup.

[0014] Furthermore, the fixed plate (31) is provided with a second movable plate (32), which is arranged on the upper part of the first movable plate (35), and the second movable plate (32) is provided with a bump block (36), a state locking mechanism (37) and a state triggering mechanism (38), and a second opening bump block (22) and a second closing bump block (24) are provided on the frame of the running track of the state triggering mechanism (38) of the second movable plate (32) clamping the seedling cup.

[0015] Compared with the prior art, the state of the clamping seedling cup of the present invention is more stable and reliable, especially when the seedlings are planted, the clamping seedling cup is used for sideways seedling placement, which is more suitable for transplanting and placing larger seedlings.
