Description

Technical Field

[0001] The utility model relates to a clamping and seedling-throwing device for seedling transplanting. Background Art

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

[0003] The current seedling transplanters mainly target smaller seedlings, and generally have relatively low requirements for the posture of the seedlings during transplanting, usually just need to be planted into the soil.

[0004] For the transplanting devices disclosed in CN2214548U, CN111976A, CN106258121A, CN201571326U, CN2619468Y, and CN110612801A, the seedling dropping is all carried out through a clamping duckbill with a fixed plate and a moving plate. During operation, the duckbill is driven by a planter to rotate. When the duckbill reaches the lowest position, it inserts into the soil and opens the moving plate to implant the seedlings placed inside into the soil, completing the seedling transplanting.

[0005] The clamping duckbills of the above-mentioned transplanting devices all drop 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 realize seedling dropping.

[0006] Due to the structural design, the clamping duckbills of the above-mentioned transplanting devices mainly have the following problems. First, the moving plate of the clamping duckbill opens and closes up and down with a small opening degree. Especially, 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, resulting in seedling dropping failure. Second, it is not easy to control the posture of the seedlings during transplanting, and the skew situation is inevitable. Third, the time to keep the moving plate of the clamping duckbill in the open state is affected by the trigger slide rail, especially by the length of the trigger slide rail, with poor running stability, making the duckbill open and close inflexibly and prone to failure.

[0007] Therefore, a clamping and seedling-throwing device for seedling transplanting with high running stability, more flexible duckbill opening and closing, especially suitable for larger seedlings, has emerged as the times require. Summary of the Invention

Specific embodiments

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Example 1: Refer to Figure 1-6 , which is a schematic structural diagram of Embodiment 1 of the present invention. It is a seedling transplanting device, including a frame. A seedling cup transmission mechanism 12 is provided on the frame. The seedling cup transmission mechanism 12 is an elliptical ring-shaped conveying chain. A seedling cup attitude stabilizing mechanism 13 is arranged in parallel with the seedling cup transmission mechanism 12. The seedling cup attitude stabilizing mechanism 13 is a conveying chain, a disc-shaped runner or a star-shaped support frame having the same structure as the seedling cup transmission mechanism 12. Moreover, the seedling cup transmission mechanism 12 and the seedling cup attitude stabilizing mechanism 13 are arranged in an up-and-down or front-and-back eccentric shape on the frame.

[0032] A clamping and seedling-throwing cup is provided on the seedling cup transmission mechanism 12. The clamping and seedling-throwing cup includes the fixed plate 31, the first connecting shaft 33 and the second connecting shaft 34. The first connecting shaft 33 and the second connecting shaft 34 are arranged on the side of the fixed plate 31 and are arranged in a straight line up and down. 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 contact block 36. The contact block 36 is a lever-shaped body, and a roller is provided at the end of the lever. A state locking mechanism 37 is provided between the first moving plate 35 and the fixed plate 31. The state locking mechanism 37 is provided with a state triggering mechanism 38. The second connecting shaft 34 of the clamping and seedling-throwing cup is connected to the seedling cup transmission mechanism 12, and the first connecting shaft 33 is connected to the seedling cup attitude stabilizing mechanism 13 of the clamping and seedling-throwing cup. A first opening contact block 21 and a first closing contact block 23 are provided on the frame along the running track of the contact block 36 of the first moving plate 35 of the clamping and seedling-throwing cup.

[0033] 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 triggering end linked with the lever.

[0034] Furthermore, the above self-locking mechanism (39) is preferably a ratchet and pawl mechanism. The ratchet of the ratchet and pawl mechanism is linked with the first moving plate (35) and is provided with a return spring. The triggering end is a pawl, and the state triggering mechanism 38 is a lever linked with the pawl.

[0035] Further, a second moving plate 32 is also provided on the above-mentioned fixed plate 31. The second moving plate 32 is arranged above the first moving plate 35, and a collision block 36, a state locking mechanism 37 and a state triggering mechanism 38 are provided on the second moving plate 32. On the frame of the running track of the state triggering mechanism 38 of the second moving plate 32 for clamping the seedling cup, a second opening contact block 22 and a second closing contact block 24 are provided.

[0036] During use, after the seedlings are put into the clamping seedling cup and run on the seedling cup transmission mechanism 12, when the clamping seedling cup runs in the area shown by the upper part H, at this time the second moving plate 32 is in an open state and the first moving plate 35 is in a closed state, and the seedlings can be put into the clamping seedling cup. The root of the seedling is placed in the barrel-shaped part formed by the first moving plate 35. When the clamping seedling cup runs to the second closing contact block 24, the state triggering mechanism 38 of the second moving plate 32 touches the second closing contact block 24, and the pawl of the ratchet and pawl mechanism releases the ratchet. The second moving plate 32 is about to clamp the stem part of the seedling. When the clamping seedling cup runs to the lower part, the collision block 36 of the first moving plate 35 touches the first opening contact block 21, and the first moving plate 35 is toggled to rotate around the hinge axis. At the same time, the ratchet of the state locking mechanism 37 of the first moving plate 35 is driven to rotate synchronously and is locked by the servo pawl 39. The first moving plate 35 is in an open state, and the soil covering mechanism 14 covers the soil for the seedlings. At this time, the second moving plate 32 still clamps the stem of the seedling, and the seedling can maintain a stable posture to complete soil covering in the area shown by I. When the soil covering is completed and the seedlings are completely positioned and shaped, the transplanting of the seedlings is completed. When the clamping seedling cup runs to the second opening contact block 22, the second moving plate 32 of the clamping seedling cup is opened, the stem of the seedling is released, and the whole seedling is released, completing the transplanting process of one seedling. For the transplanting of larger seedlings, especially for the transplanting of saplings, the effect is particularly remarkable.

[0037] Of course, if only the first moving plate 35 is provided on the above-mentioned clamping seedling cup, it is mainly suitable for the transplanting of smaller seedlings.
