Description

Technical Field

[0001] This invention relates to the field of grafting equipment technology, specifically to a protective device for grafting Camellia oleifera branches. Background Technology

[0002] Plant grafting can effectively improve the quality and yield of fruits and vegetables, and enhance their cold and drought resistance. Manual grafting requires skilled techniques and a high level of expertise, is labor-intensive, has a low survival rate, and requires a very short grafting period to complete a large number of grafts in a short time. These factors have driven the development of automated grafting machinery.

[0003] Currently, when clamping rootstocks, multiple cylinders are often used to clamp both ends of the rootstock to provide sufficient working space for the clamps to secure the rootstock and scion after grafting. However, using multiple cylinders requires controlling the movement of each cylinder individually, and the grafting and clamping of the rootstock and scion can only be achieved through the coordinated action of multiple cylinders. This operation process is relatively complex, with a complicated structure and cumbersome movements. Furthermore, using multiple cylinders increases the production cost of the device.

[0004] Therefore, we have made improvements and proposed a protective device for grafting camellia branches. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a protective device for grafting Camellia oleifera branches, which solves the problems of complex operation procedures and structures and high production costs in existing technologies.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a protective device for grafting Camellia oleifera branches, comprising a seedling clamping finger cylinder, an installation plate, a slide rail plate, micro sliders, an upper left clamp, an upper right clamp, a lower left clamp, and a lower right clamp. The installation plate is fixedly installed at the upper end of the seedling clamping finger cylinder. The slide rail plate is horizontally fixedly installed on the installation plate. Two micro sliders are provided and symmetrically slidably installed on the slide rail plate. The upper left clamp is fixedly installed on the micro slider on the left side of the slide rail plate, and the upper right clamp is fixedly installed on the micro slider on the right side of the slide rail plate. The lower left clamp is installed on the left front end of the seedling clamping finger cylinder, and the lower right clamp is installed on the right front end of the seedling clamping finger cylinder.

[0011] The lower left and lower right grippers are symmetrically arranged with symmetrical fixing grooves on their front sidewalls;

[0012] The fixing grooves of the upper left and upper right clamps are combined to form a hole and groove structure for fixing the camellia branches, and the fixing grooves of the lower left and lower right clamps are combined to form a hole and groove structure for fixing the camellia branches.

[0013] As a preferred embodiment, the fixing grooves of the upper left and upper right grippers are symmetrically arranged with the fixing grooves of the lower left and lower right grippers overlapping vertically.

[0014] As a preferred embodiment, the upper left and upper right grippers are provided with a limiting groove at the bottom of their front ends, and the lower left and lower right grippers are provided with a limiting pin at the top of their front ends. The limiting pin is slidably disposed in the limiting groove and is located on the side away from the fixed clamping groove.

[0015] As a preferred embodiment, the upper left gripper and the upper right gripper are provided with ball bearing through holes at the middle of their rear ends, and the bottom of the inner cavity of the ball bearing through holes is elastically connected to a ball bearing by a spring.

[0016] The lower left and lower right grippers are symmetrically provided with a first ball limiting hole and a second ball limiting hole on their rear ends, respectively. The balls can be moved into the first ball limiting hole and the second ball limiting hole by moving the upper left and upper right grippers.

[0017] As a preferred embodiment, the first ball bearing limiting hole is located on the side closer to the fixed clamping groove, and the second ball bearing limiting hole is located on the side farther away from the fixed clamping groove.

[0018] As a preferred embodiment, a cutter is provided at the upper middle position of the upper left gripper and the upper right gripper, and a top block is fixedly connected to the rear of the cutter.

The inclined top surfaces of the top block can cooperate with the inclined pushing surfaces of the upper left and upper right grippers to separate the upper left and upper right grippers.

[0021] The present invention has the following beneficial effects:

[0022] Through the ingenious design of the mechanical structure, the action of a single cylinder causes the upper and lower grippers to appear in three different positions, which not only reduces the amount of cylinder equipment used, but also simplifies the structure and facilitates the grafting of rootstock.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0048] The slide rail plate 3 is provided with baffles 22 at both ends, which can restrict the displacement of the micro slider 4.

[0049] Working principle of the invention:

[0050] Initial state:

[0051] The finger-clamping cylinder 1 is in the open state, that is, the lower left clamping jaw 7 and the lower right clamping jaw 8 are in the separated state, and the ball is located in the first ball limiting hole 15.

[0052] Action process:

[0053] 1. When the rootstock is placed and needs to be fixed, the clamping finger cylinder 1 closes, the lower left clamp 7 and the lower right clamp 8 clamp the rootstock, and the upper left clamp 5 and the upper right clamp 6 clamp the upper part of the rootstock under the spring compression block of the micro slider 4 and the elastic action of the spring to complete the seedling support action.

[0054] 2. When splitting the rootstock, the cutter 17 falls under the action of the hydraulic cylinder 19. The inclined top surface 20 of the top block 18 separates the upper left clamping jaw 5 and the upper right clamping jaw 6 through the inclined pushing surface 21 of the upper left clamping jaw 5 and the upper right clamping jaw 6. The balls of the upper left clamping jaw 5 and the upper right clamping jaw 6 enter the second ball limiting hole 16 through the first ball limiting hole 15. Under the action of the spring in the ball through hole 14, the balls are fixed in the second ball limiting hole 16. At this time, the lower left clamping jaw 7 and the lower right clamping jaw 8 are still in the clamping state, while the upper left clamping jaw 5 and the upper right clamping jaw 6 are in the separated state.

[0055] 3. The cutter 17 rises under the drive of the hydraulic cylinder 19, while the upper left clamp 5 and upper right clamp 6 remain separated, providing the clamping position for the upper clamping action during grafting. Wait for the grafting to complete.

[0056] 4. After grafting, when it is necessary to loosen the seedling, open the seedling clamping finger cylinder 1, loosen the lower left clamp 7 and the lower right clamp 8, and the grafted seedling will fall off.

[0057] At this point, the upper left gripper 5 and upper right gripper 6 should have opened further in line with the lower left gripper 7 and lower right gripper 8, but they are restricted by the limiting groove 12 and limiting pin 13 and cannot open further. Instead, when the limiting pin 13 touches the end of the limiting groove 12, it forces the ball to slide into the first ball limiting hole 15. At this point, the lower left gripper 7 and lower right gripper 8 are open, and the upper left gripper 5 and upper right gripper 6 open to the same extent as the lower left gripper 7 and lower right gripper 8. This is the initial state, which is ready for the next step of clamping the seedling.
