Description

Technical Field

[0001] The utility model relates to the technical field of grafting jaws, in particular to an elastic sticking grafting jaw for seedlings. Background Art

[0002] During the current sticking process of solanaceous rootstocks and scion seedlings, the scion seedling jaw is rigid in the direction of the hypocotyl axis center line, and the stroke of the sticking cylinder is fixed. Therefore, each scion seedling always moves to a fixed position towards the rootstock. However, after the cutting surfaces of the actual rootstock and scion seedlings are completed, there is always an axial position deviation of up to several millimeters (longer or shorter) in the cutting surface. This often leads to poor sticking of the axial sticking surface (over-sticking or under-sticking), thus affecting the grafting effect and even resulting in grafting failure. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the prior art, the utility model provides an elastic sticking grafting jaw for seedlings, which solves the problem that when the scion seedling jaw drives the scion seedling to stick to the rootstock, due to the rigid arrangement of the sticking jaw, it is easy to cause over-sticking or under-sticking phenomena in the sticking of the scion seedling and the rootstock.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] An elastic sticking grafting jaw for seedlings, comprising a pneumatic finger and two scion seedling jaws arranged on two movable ends of the pneumatic finger. A scion seedling jaw seat is fixedly connected to the pneumatic finger. An elastic jaw seat is linearly and elastically slidably connected to the scion seedling jaw along the length direction of the pneumatic finger. The two scion seedling jaws are arranged in a limited linear sliding manner on both sides of the elastic jaw seat. A limit connection is arranged between the movable end and the scion seedling jaw. The scion seedling jaw realizes the clamping or loosening action under the drive of the pneumatic finger. Under the action of an external force, the elastic jaw seat drives the scion seedling jaw to move synchronously.

[0008] Preferably, an elastic guiding shaft is fixedly arranged on the scion seedling jaw seat. The elastic clamping seat is limitedly sleeved on the elastic guiding shaft. An elastic sleeve is sleeved outside the elastic guiding shaft in the inner cavity of the elastic clamping seat.

[0009] Preferably, a linear guiding shaft is fixedly arranged on the scion seedling jaw seat. The elastic clamping seat is slidably connected to the linear guiding shaft. The elastic guiding shaft is arranged between the two linear guiding shafts.

[0010] Preferably, a fixed sleeve is fixedly arranged on the elastic clamping seat. A clamping guiding shaft is fixedly connected to the fixed sleeve. The scion seedling jaw is slidably arranged on the clamping guiding shaft.

[0011] Preferably, a linear bearing is fixedly arranged on the spikelet clamping jaw, and the linear bearing is slidably connected with the clamping guide shaft.

[0012] Preferably, fixing plates are fixedly arranged on both sides of the spikelet clamping jaw through screws, the clamping guide shaft penetrates through the fixing plates, a limiting groove is formed in the spikelet clamping jaw, and the movable end is inserted into the limiting groove.

[0013] (III) Beneficial effects

[0014] The utility model has the following beneficial effects:

[0015] For the elastic bonding clamping jaw for seedling grafting, through the arranged elastic clamping seat, an elastic contraction function in the axial direction of the seedling hypocotyl axis is added to the spikelet clamping jaw. After the cut spikelet is clamped by the spikelet clamping jaw and moves towards the rootstock under the drive of the bonding cylinder, at the last stage of the stroke, the rootstock and the cut surface of the spikelet start to contact. The acting force of the fixed-position rootstock on the spikelet forces the elastic clamping seat to perform appropriate elastic contraction, so as to achieve just-right bonding every time, without under-bonding or over-bonding, ensuring the bonding effect and improving the grafting quality.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0022] Please refer to Figure 1 , the present utility model provides a technical solution: a resilient grafting clamping jaw for seedlings, comprising a pneumatic finger 1 and two ear seedling clamping jaws 5 provided on two movable ends 2 of the pneumatic finger 1. A clamping jaw seat 3 for ear seedlings is fixedly connected to the pneumatic finger 1. An elastic jaw seat 4 is linearly and elastically slidably connected to the ear seedling clamping jaw 5 along the length direction of the pneumatic finger 1. The two ear seedling clamping jaws 5 are arranged in a limited linear sliding manner on both sides of the elastic jaw seat 4. A limiting connection is provided between the movable end 2 and the ear seedling clamping jaw 5. The ear seedling clamping jaw 5 realizes the clamping or loosening action driven by the pneumatic finger 1. Under the action of an external force, the elastic jaw seat 4 drives the ear seedling clamping jaw 5 to move synchronously.

[0023] In the present utility model, through the provided elastic jaw seat, an elastic contraction function in the axial direction of the seedling hypocotyl is added to the ear seedling clamping jaw 5. After the cut ear seedling is clamped by the ear seedling clamping jaw 5, it moves towards the rootstock under the drive of the grafting cylinder. At the last stage of the stroke, the rootstock and the cut surface of the ear seedling start to contact. The force exerted by the fixed-position rootstock on the ear seedling forces the elastic jaw seat to perform appropriate elastic contraction, thereby ensuring that each grafting is just right, without under-grafting or over-grafting, guaranteeing the grafting effect and improving the grafting quality.

[0024] Refer to Figure 2 and 3 As shown, in this embodiment, an elastic guiding shaft 42 is fixedly provided on the clamping jaw seat 3 for ear seedlings. The elastic jaw seat is limitedly sleeved on the elastic guiding shaft 42. An elastic sleeve 43 is sleeved outside the elastic guiding shaft 42 in the inner cavity of the elastic jaw seat. By providing the elastic guiding shaft 42 and the elastic sleeve 43, the sliding of the elastic jaw seat can be limited, and at the same time, under the elastic deformation of the elastic sleeve 43, the elastic jaw seat and the ear seedling clamping jaw 5 arranged thereon can be driven to generate elastic contraction and automatic resetting suitable for grafting.

[0025] In this embodiment, a linear guiding shaft is fixedly provided on the clamping jaw seat 3 for ear seedlings. The elastic jaw seat is slidably connected to the linear guiding shaft. The elastic guiding shaft 42 is arranged between the two linear guiding shafts.

[0026] In this embodiment, a fixed sleeve 44 is fixedly provided on the elastic jaw seat. A clamping guiding shaft 52 is fixedly connected to the fixed sleeve 44. The ear seedling clamping jaw 5 is slidably arranged on the clamping guiding shaft 52.

[0027] Refer to Figure 3 As shown, in this embodiment, a linear bearing 53 is fixedly provided on the ear seedling clamping jaw 5. The linear bearing 53 is slidably connected to the clamping guiding shaft 52. By providing the linear bearing 53 and the clamping guiding shaft 52, it can effectively ensure that the ear seedling clamping jaw 5 smoothly realizes the clamping or loosening action of the ear seedling driven by the pneumatic finger 1.

[0028] In this embodiment, fixing plates 54 are fixedly arranged on both sides of the spikelet gripper 5 through screws. The clamping guide shaft 52 penetrates through the fixing plate 54. A limiting groove is formed in the spikelet gripper, and the movable end is inserted into the limiting groove. Through the arranged limiting groove, the movable end can drive the spikelet gripper to move synchronously, without affecting the elastic contraction or reset of the spikelet gripper along with the elastic claw seat.
