Description

Technical Field

[0001] The utility model relates to the technical field of automatic grafting, in particular to a limiting pinching, releasing device for a seedling grafting clip. Background Technique

[0002] When the current melon grafting is bandaged, when the grafting clip jaw pinches the butterfly clip from the butterfly clip positioning pin, during the deformation process of the clip legs, the clip will move backward slightly due to the force, resulting in inaccurate pinching position of the clip, and it is also an obstacle to unify the pinching positions of butterfly clips of different specifications; in addition, when bandaging the grafted rootstock and scion seedlings, the butterfly clip will also move backward slightly during the closing process, and at the same time, the misalignment of the rootstock and scion seedlings cannot be corrected. For the above reasons, the bandaging effect is poor, that is, the grafting effect is poor, and some even fail, reducing the survival rate of the overall grafted seedlings. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the prior art, the utility model provides a limiting pinching, releasing device for a seedling grafting clip, which solves the problems that during the existing automatic grafting process, when the rootstock and scion seedlings are grafted and bandaged through a butterfly clip, the butterfly clip is prone to move backward during the pinching process, and at the same time, there is a lack of corrective measures for the misalignment of the rootstock and scion seedlings during the grafting process, resulting in poor overall grafting effect.

[0005] (2) Technical Solutions

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

[0007] A limiting pinching, releasing device for a seedling grafting clip includes a pneumatic finger and a grafting clip jaw driven by the pneumatic finger. A limiting plate is arranged between the grafting clip jaws, and the limiting plate is used to press against one side of the butterfly clip to prevent it from moving backward when clamping the scion hypocotyl and the rootstock hypocotyl; misalignment push plates are symmetrically arranged vertically in the direction perpendicular to the grafting clip jaw, and the misalignment push plates are used to extend to force the skewed rootstock or scion hypocotyl to return to the predetermined grafting position.

[0008] Preferably, a connecting frame plate is fixedly arranged on one side of the pneumatic finger, and a pushing cylinder is fixedly arranged on the connecting frame plate, and the pushing cylinder is used to push the misalignment push plate to move along the length direction of the connecting frame plate.

[0012] Preferably, a groove matching the shape of one side surface of the butterfly clip is arranged at one end of the limiting plate.

[0013] (III) Beneficial effects

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

[0015] For the seedling grafting clip limiting pinching, releasing and holding device, through the arranged grafting jaws, the jaws are closed to pinch the butterfly clip from the positioned butterfly clip positioning pin in place, completing the pinching of the butterfly clip; before the grafting jaws move to the grafting position, the misaligned push plate that protrudes in the up and down directions in advance contacts the crooked rootstock or scion hypocotyl, which can force the hypocotyl to return to the predetermined grafting position; when the grafting jaws reach the bandaging point, the butterfly clip is released, and the butterfly clip starts to close and clamp the grafting part of the rootstock and the scion hypocotyl, and the backward thrust during the closing process of the butterfly clip is offset by the limiting plate in the middle of the grafting jaws, so that the butterfly clip stably grafts the scion and the rootstock, improving the overall survival rate of grafting.

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

[0022] Please refer to Figure 1 , the present utility model provides a technical solution: a seedling grafting clip limiting pinching and releasing device, which includes a pneumatic finger 3 and a grafting clip jaw 4 driven by the pneumatic finger 3. A limiting plate 6 is arranged between the grafting clip jaws 4, and the limiting plate 6 is used to press against one side of the butterfly clip to prevent it from retreating when clamping the scion embryo axis and the rootstock embryo axis; a dislocation push plate 24 is symmetrically arranged up and down in the direction perpendicular to the grafting clip jaw 4, and the dislocation push plate 24 is used to extend to force the skewed rootstock or scion embryo axis to return to a predetermined grafting position.

[0023] In the present utility model, through the provided grafting clip jaw 4, the clip jaw is closed to pinch the butterfly clip from the positioned butterfly clip positioning pin, completing the pinching of the butterfly clip; before the grafting clip jaw 4 moves to the grafting position, the dislocation push plate 24 that extends in advance in the up and down direction contacts the skewed rootstock or scion embryo axis (if there is no skew, it will not touch the embryo axis), which can force the embryo axis to return to the predetermined grafting position; when the grafting clip jaw 4 reaches the bandaging point, the butterfly clip is released, and the butterfly clip starts to close to clamp the grafting part of the rootstock and the scion embryo axis, and the backward thrust of the butterfly clip during the closing process is offset by the limiting plate 6 in the middle of the grafting clip jaw 4, so that the butterfly clip stably grafts the scion and the rootstock, improving the overall grafting survival rate.

[0024] Refer to Figure 1 And 4 As shown, in this embodiment, a connecting frame plate 1 is fixedly arranged on one side of the pneumatic finger 3, and a pushing cylinder 2 is fixedly arranged on the connecting frame plate 1. The pushing cylinder 2 is used to push the dislocation push plate 24 to move along the length direction of the connecting frame plate 1. Through the provided pushing cylinder 2, before the grafting clip jaw 4 releases the butterfly clip to clamp the embryo axis, the dislocation push plate 24 can be misaligned to contact the skewed rootstock or scion embryo axis (if there is no skew, it will not touch the embryo axis), which can force the embryo axis to return to the predetermined grafting position, effectively avoiding the situation that the subsequent butterfly clip grafting effect is affected due to the skewness of the embryo axis.

[0025] Refer to Figure 2 And 3 As shown, in this embodiment, a fixing block 21 is fixedly arranged on the connecting frame plate 1 by screws, and the fixing block 21 and the pushing cylinder 2 are fixedly connected by screws. Through the provided fixing block 21, the whole pushing cylinder 2 can be conveniently installed or disassembled in cooperation with the screws, improving the efficiency of daily maintenance work.

[0026] In this embodiment, a movable block 22 is fixedly arranged at the piston end of the driving cylinder 2. A movable frame 23 is detachably connected to the movable block 22. The misaligned push plate 24 is fixedly arranged at one end of the movable frame 23 away from the driving cylinder 2.

[0027] Referring to Figure 2 As shown, in this embodiment, a fixed frame 5 is fixedly arranged on one side of the pneumatic finger 3 close to the grafting jaw 4. The limiting plate 6 is detachably installed at one end of the fixed frame 5. By arranging the limiting plate 6, it can move synchronously with the grafting jaw 4. When the grafting jaw 4 clamps the butterfly clip, the limiting plate 6 is also clamped at the same time. When the grafting jaw 4 is released, the butterfly clip closes again to complete the grafting clamping between the hypocotyls. At this time, the limiting plate 6 effectively restricts the backward movement of the butterfly clip, ensuring that the entire butterfly clip grafting clamping process is not prone to position deviation and improving the grafting effect.

[0028] In this embodiment, a groove matching the shape of one side surface of the butterfly clip is arranged at one end of the limiting plate 6.
