Description

Technical Field

[0001] This invention relates to a seedling transplanting device. Background Technology

[0002] With the development of agricultural technology, the advantages of transplanting seedlings are very obvious, and therefore it is being used more and more widely in the planting industry, especially in large-scale agricultural planting, where the advantages of transplanting seedlings by transplanting machines are even more prominent.

[0003] Current seedling transplanters are mainly designed for smaller seedlings. Smaller seedlings generally do not have high requirements for their posture during transplanting; they can usually be simply placed into the soil.

[0004] The transplanting devices disclosed in CN221429548U, CN111976A, CN106258121A, CN201571326U, CN2619468Y, and CN110612801A all use a clamping duckbill with a fixed plate and a moving plate to place the seedlings. During operation, the planter drives the duckbill to rotate. When the duckbill reaches the bottom, it inserts into the soil and opens the moving plate, planting the seedlings placed inside into the soil, thus completing the seedling transplanting.

[0005] The above-mentioned transplanting device uses a clamping beak to deliver seedlings by setting a contact block on a moving plate and a trigger rail on the moving track of the moving plate. When the contact block touches the trigger rail, the moving plate opens, thus delivering the seedlings.

[0006] Due to structural design limitations, the aforementioned transplanting device's clamping spout has the following main problems: First, the moving plate of the clamping spout opens and closes vertically with a small degree of opening and closing. In particular, the fixed plate is a barrel-shaped body, which is only suitable for smaller seedlings. Larger seedlings are easily stuck by the barrel-shaped body, causing transplanting failure. Second, the posture of the seedlings is difficult to control during transplanting, and skewing is unavoidable. Third, the time it takes for the moving plate of the clamping spout to remain open is affected by the trigger slide rail, especially by the length of the trigger slide rail, resulting in poor operational stability, making the spout inflexible in opening and closing, and prone to malfunction.

[0007] Therefore, a seedling transplanting device with high operational stability, more flexible duckbill opening and closing, and especially suitable for larger seedlings was developed. Summary of the Invention

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

[0009] To achieve the above objectives, the present invention provides the following technical solution: including a frame, on which a seedling cup transmission mechanism (12) is provided, characterized in that the seedling cup transmission mechanism (12) is provided with a clamping and feeding cup, the clamping and feeding cup including a fixed plate (31), a first connecting shaft (33) and a second connecting shaft (34), a first moving plate (35) is provided on the fixed plate (31), the first moving plate (35) is horizontally hinged to the fixed plate (31) and is provided with a collision block (36), a state locking mechanism (37) is provided between the first moving 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 with the first moving plate (35), and the state triggering mechanism (38) includes a lever and a trigger end linked with the lever.

[0011] Furthermore, the self-locking mechanism (39) mentioned above is preferably a ratchet mechanism, in which the ratchet is linked to the first moving plate (35), and the trigger end is a pawl.

[0012] Alternatively, the self-locking mechanism (39) is a locking tongue mechanism: it includes a rotating wheel that is linked with the first moving plate (35), and the rotating wheel is provided with protruding teeth or recesses, and the trigger end is the corresponding recess or protruding teeth.

[0013] The seedling cup transmission mechanism (12) is a ring-shaped conveying chain, a disc-shaped wheel, or a star-shaped support frame. A seedling cup posture stabilization mechanism (13) is provided in parallel with the seedling cup transmission mechanism (12). The seedling cup posture stabilization mechanism (13) is a conveying chain, a disc-shaped wheel, or a star-shaped support frame with the same structure as the seedling cup transmission mechanism (12). The seedling cup transmission mechanism (12) and the seedling cup posture stabilization mechanism (13) are arranged eccentrically on the frame, either vertically or horizontally. The second connecting shaft (34) that holds 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 stabilization mechanism (13) that holds the seedling cup.

[0014] Furthermore, the aforementioned fixed plate (31) is provided with a second movable plate (32), which is located above the first movable plate (35). The second movable plate (32) is provided with a contact block (36), a state locking mechanism (37), and a state triggering mechanism (38). A second opening contact block (22) and a second closing contact block (24) are provided on the frame along the running trajectory of the state triggering mechanism (38) of the second movable plate (32) that holds the seedling cup.

[0015] Compared with the prior art, the clamping and seedling cup of the present invention is more stable and reliable. In particular, when seedlings are being placed, the clamping and seedling cup is used to place the seedlings on the side, which is more suitable for transplanting larger seedlings.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: Refer to Figure 1-6The diagram below is a schematic diagram of the structure of Embodiment 1 of the present invention, which is a seedling transplanting device. It includes a frame and a seedling cup transmission mechanism 12 on the frame. The seedling cup transmission mechanism 12 is an elliptical ring-shaped conveyor chain. A seedling cup posture stabilizing mechanism 13 is provided in parallel with the seedling cup transmission mechanism 12. The seedling cup posture stabilizing mechanism 13 is a conveyor chain, a disc-shaped wheel, or a star-shaped support frame with the same structure as the seedling cup transmission mechanism 12. The seedling cup transmission mechanism 12 and the seedling cup posture stabilizing mechanism 13 are arranged eccentrically on the frame, either vertically or front-back.

[0031] A seedling cup clamping mechanism 12 is provided, comprising a fixed plate 31, a first connecting shaft 33, and a second connecting shaft 34. The first connecting shaft 33 and the second connecting shaft 34 are located on the side of the fixed plate 31 and arranged vertically in a straight line. A first movable plate 35 is provided on the fixed plate 31, which is horizontally hinged to the fixed plate 31 and has a stop block 36. The stop block 36 is a lever-shaped body with a roller at the end. A state locking mechanism 37 is provided between the first movable plate 35 and the fixed plate 31, and the state locking mechanism 37 has a state triggering mechanism 38. The second connecting shaft 34 of the seedling cup clamping mechanism is connected to the seedling cup transmission mechanism 12, and the first connecting shaft 33 is connected to the seedling cup posture stabilization mechanism 13 of the seedling cup clamping mechanism. A first opening contact block 21 and a first closing contact block 23 are provided on the frame along the running trajectory of the stop block 36 of the first movable plate 35 clamping the seedling cup.

[0032] Furthermore, the state locking mechanism (37) is a self-locking mechanism (39) linked with the first moving plate (35), and the state triggering mechanism (38) includes a lever and a trigger end linked with the lever.

[0033] Furthermore, the self-locking mechanism (39) mentioned above is preferably a ratchet mechanism, in which the ratchet is linked with the first moving plate (35) and is provided with a return spring, the trigger end is a pawl, and the state triggering mechanism 38 is a lever linked with the pawl.

[0034] Furthermore, the aforementioned fixed plate 31 is also provided with a second movable plate 32, which is disposed above the first movable plate 35, and the second movable plate 32 is provided with a contact block 36, a state locking mechanism 37, and a state triggering mechanism 38. A second opening contact block 22 and a second closing contact block 24 are provided on the frame along the running trajectory of the state triggering mechanism 38 of the second movable plate 32 that holds the seedling cup.

[0035] In use, after a seedling is placed in the seedling cup and the seedling cup transmission mechanism 12 is running, when the seedling cup is running in the area shown in the upper H, the second moving plate 32 is in the open state and the first moving plate 35 is in the closed state, allowing the seedling to be placed into the seedling cup. The root of the seedling is placed in the barrel-shaped part formed by the first moving plate 35. When the seedling cup runs to the second closed contact block 24, the state triggering mechanism 38 of the second moving plate 32 touches the second closed contact block 24, and the pawl of the ratchet and ratchet mechanism releases the ratchet, and the second moving plate 32 clamps the stem of the seedling. When the seedling cup runs to the lower part, the contact block 36 of the first moving plate 35 touches the first open contact block 21, and the first moving plate 35 is moved to hinge. As the shaft rotates, the ratchet of the locking mechanism 37 of the first moving plate 35 is driven to rotate synchronously and locked by the servo pawl 39. The first moving plate 35 is in the open state, and the soil covering mechanism 14 covers the seedling with soil. At this time, the second moving plate 32 still holds the stem of the seedling, which can keep the seedling in a stable posture and complete the soil covering in the area shown in I. When the soil covering is completed, the seedling has been completely positioned and shaped, and the transplanting of the seedling is completed. When the seedling cup is held to the second opening contact block 22, the second moving plate 32 holding the seedling cup is opened, the stem of the seedling is released, and the entire seedling is released, completing the transplanting process of a seedling. For the transplanting of larger seedlings, especially for the transplanting of tree seedlings, the effect is particularly significant.

[0036] Of course, if the above-mentioned clamping and seedling cup is only equipped with the first moving plate 35, it is mainly suitable for transplanting smaller seedlings.

[0037] Example 2: Refer to Figure 7 The diagram below is a structural schematic of Embodiment 2 of the present invention. In this embodiment, the first connecting shaft 33 is located in the middle of the fixed plate 31, and the second connecting shaft 34 is located on the side of the fixed plate 31.

[0038] Of course, the ratchet of the state locking mechanism 37 can also be a segment of an arc-shaped body with ratchet teeth.

[0039] Example 3: Reference Figure 8 The diagram below is a structural schematic of Embodiment 3 of the present invention. In this embodiment, the self-locking mechanism (39) is a locking tongue mechanism: it includes a rotating wheel that is linked with the first moving plate (35), and a recess is provided on the rotating wheel. The trigger end is a corresponding protruding tooth.

[0040] Of course, the rotating wheel of the state locking mechanism 37 can also be composed of an arc-shaped body.

[0041] Example 4: Reference Figure 9The diagram below is a structural schematic of Embodiment 4 of the present invention. In this embodiment, the self-locking mechanism (39) is a locking tongue mechanism: it includes a rotating wheel that is linked with the first moving plate (35), and the rotating wheel is provided with protruding teeth. The trigger end is a corresponding recess.

[0042] Example 5: Refer to Figure 10 The diagram below is a structural schematic of Embodiment 5 of the present invention. In this embodiment, the seedling cup transmission mechanism 12 is an inverted trapezoidal annular conveyor chain.

[0043] Example 6: Refer to Figure 11 The diagram below is a structural schematic of Embodiment 6 of the present invention. In this embodiment, the seedling cup transmission mechanism 12 is a circular annular conveyor chain.

[0044] Example 7: Refer to Figure 12 The diagram below is a structural schematic of Embodiment 7 of the present invention. In this embodiment, the seedling cup transmission mechanism 12 is a star-shaped support frame.
