It can realize the automation and standardization of the grafting process, improve the grafting speed and survival rate, and reduce labor costs. Camellia oleifera grafting machine generally adopts cleft grafting for grafting. The grafting process is: manually feeding the rootstock seedlings and scion seedlings, and the machine automatically cuts and splits the rootstock, cuts the scion, docks the scion and the rootstock, and clamps. At present, when cutting and clamping the camellia oleifera rootstock, the finger cylinder is used to drive the seedling clamping claw to clamp the camellia oleifera rootstock. In order to cut the upper part of the camellia oleifera rootstock, a part of the camellia oleifera rootstock needs to be exposed above the seedling clamping claw. This part of the camellia oleifera rootstock is prone to skewness, which can easily lead to the incorrect cutting position of the camellia oleifera rootstock, affecting the clamping grafting and the grafting survival rate. Therefore, it is necessary to design an automatic seedling clamping claw device for the camellia oleifera grafting machine to improve the above problems. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example: See Figure 1-Figure 5The present embodiment provides an automatic seedling-supporting clamping device for a tea oil grafting machine, comprising a mounting base 1, the mounting base 1 is mounted on the tea oil grafting machine, a seedling-supporting finger cylinder 2 is fixedly mounted on the bottom of the mounting base 1, and a driving end of the seedling-supporting finger cylinder 2 is fixedly connected to two lower clamping jaws 3, and the seedling-supporting finger cylinder 2 is used to drive the two lower clamping jaws 3 to move synchronously close or away, and a lower seedling-supporting groove 301 for clamping the tea oil rootstock is provided on the opposite side of the two lower clamping jaws 3, and an upper clamping jaw 6 is provided above each lower clamping jaw 3, and an upper seedling-supporting groove 601 for straightening the tea oil rootstock is provided on the opposite side of the two upper clamping jaws 6, and the upper clamping jaw 6 can move along the X-axis direction of the lower clamping jaw 3, and a positioning structure is provided between the upper clamping jaw 6 and the lower clamping jaw 3. The positioning structure is used to locate the relative position of the upper clamping jaw 6 and the lower clamping jaw 3, and also includes a rootstock chopping knife mechanism 11 arranged above the upper clamping jaw 6. The rootstock chopping knife mechanism 11 is installed on the longitudinal driving member of the oil tea grafting machine. The longitudinal driving member drives the rootstock chopping knife mechanism 11 to move longitudinally for chopping the oil tea rootstock. When in use, the oil tea rootstock is placed between the two lower clamping jaws 3, and the two lower clamping jaws 3 are driven to close by the action of the seedling clamping finger cylinder 2 to clamp the oil tea rootstock in the lower seedling clamping groove 301. At the same time, the upper clamping jaw 6 moves synchronously with the lower clamping jaw 3, and the two upper clamping jaws 6 are also closed to complete the seedling supporting action of the oil tea rootstock, thereby avoiding position deviation of the oil tea rootstock during chopping or grafting, improving the success rate of grafting, and having high practicality.

[0024] In this embodiment, if Figure 3 、 Figure 4 and Figure 5 As shown, the positioning structure includes a steel ball 9, a mounting groove 602 is provided at the bottom of the upper clamping jaw 6, the steel ball 9 is installed in the mounting groove 602, a compression spring 8 is installed between the steel ball 9 and the top of the mounting groove 602, and a first positioning hole 302 and a second positioning hole 303 are provided on the top of the lower clamping jaw 3. The first positioning hole 302 and the second positioning hole 303 are used for the steel ball 9 to be inserted. The first positioning hole 302 is located on the side where the two lower clamping jaws 3 are close to each other, and the second positioning hole 303 is located on the side where the two lower clamping jaws 3 are away from each other. When the steel ball 9 is inserted into the first positioning hole 302, the upper clamping jaw 6 and the lower clamping jaw 3 are aligned. At this time, the upper jaw 6 moves along with the closing action of the lower jaw 3, so that the upper jaw 6 also completes the closing action, and the oil tea rootstock is supported. When the steel ball 9 is stuck in the second positioning hole 303, the upper jaw 6 and the lower jaw 3 are staggered. At this time, the lower jaw 3 is in a closed state, and the upper jaw 6 is in an open state. This action state occurs when the rootstock chopping knife mechanism 11 cleaves the oil tea rootstock. When the rootstock chopping knife mechanism 11 rises away from the oil tea rootstock, the upper jaw 6 still maintains the open position, which just provides the position of the clamp for the upper clamping action during grafting, which helps the grafting work of the oil tea rootstock.

[0025] Furthermore, if Figure 1 and Figure 2 As shown, the cross-section of the chopping knife mounting block of the rootstock chopping knife mechanism 11 is a triangular structure, one of the tips of the chopping knife mounting block is facing downward, and the tops of the opposite sides of the two upper clamping jaws 6 are set as inclined surfaces that slide with the chopping knife mounting block. When the rootstock chopping knife mechanism 11 moves downward to chop the oil tea rootstock, the chopping knife mounting block of the rootstock chopping knife mechanism 11 contacts the inclined surfaces of the upper clamping jaws 6, thereby pushing the two upper clamping jaws 6 to open and move away, so that the steel ball 9 disengages from the first positioning hole 302 and moves to be clamped in the second positioning hole 303.

[0026] In this embodiment, if Figure 2 As shown, the top of the mounting base 1 is fixedly connected to a slide rail 4 arranged along the X-axis direction, and the bottom of each upper clamping jaw 6 is fixedly connected to a micro slider 5, which is slidably connected to the slide rail 4, and both ends of the slide rail 4 are fixedly connected to a slide rail baffle 401. When the upper clamping jaw 6 moves, the upper clamping jaw 6 slides on the slide rail 4 through the micro slider 5, which guides the upper clamping jaw 6 and improves the stability and smoothness of the movement of the upper clamping jaw 6.

[0027] In this embodiment, if Figure 2 As shown, a tension spring 7 is fixedly connected between the two micro-sliders 5. The tension spring 7 can drive the two micro-sliders 5 closer together, thereby bringing the two upper clamps 6 closer together to assist in straightening the oil tea rootstock. It should be noted that the force of the tension spring 7 is not enough to pull the steel ball 9 out of the first positioning hole 302 and the second positioning hole 303.

[0028] In this embodiment, if Figure 4 and Figure 5 As shown, the top of the lower clamping jaw 3 is fixedly connected to the limiting column 10, and the bottom of the upper clamping jaw 6 is provided with a limiting groove 603 along the X-axis direction. The top end of the limiting column 10 is slidably set in the limiting groove 603. The setting of the limiting column 10 and the limiting groove 603 is used to limit the relative displacement distance between the upper clamping jaw 6 and the lower clamping jaw 3.

[0029] In this embodiment, if Figure 2 As shown, the positions of the lower seedling clamping groove 301 and the upper seedling clamping groove 601 correspond to each other up and down, so that when the lower seedling clamping groove 301 clamps the oil-tea camellia rootstock, the upper seedling clamping groove 601 can support the oil-tea camellia rootstock. The cross-section of the lower seedling clamping groove 301 and the upper seedling clamping groove 601 is a V-shaped structure. Through the shape design of the lower seedling clamping groove 301 and the upper seedling clamping groove 601, it is suitable for clamping oil-tea camellia rootstocks of different diameters.

[0030] Working principle: When in use, the seedling clamping finger cylinder 2 is in the open state, that is, the two lower clamping jaws 3 are in the open position. At this time, the steel ball 9 is clamped into the first positioning hole 302 under the action of the compression spring 8, and then the oil-tea rootstock is placed between the two lower clamping jaws 3. The seedling clamping finger cylinder 2 is actuated and the two lower clamping jaws 3 are clamped and closed to clamp the oil-tea rootstock. The upper clamping jaw 6 moves synchronously with the lower clamping jaw 3 and also closes to complete the seedling-supporting action of the oil-tea rootstock.

[0031] Then the rootstock chopping knife mechanism 11 moves downward to chop the oil-tea camellia rootstock. The chopping knife mounting block of the rootstock chopping knife mechanism 11 contacts the inclined surface of the upper clamping jaw 6, thereby pushing the two upper clamping jaws 6 to open and move away, so that the steel ball 9 is disengaged from the first positioning hole 302 and moves to be clamped in the second positioning hole 303. At this time, the lower clamping jaw 3 is still in a clamped state, and there is a 12mm open space between the upper clamping jaws 6.

[0032] After the oil tea rootstock is split, the rootstock splitting knife mechanism 11 rises, and the upper clamping jaws 6 remain in the open position, just providing the clamp position for the clamping action during grafting, waiting for the grafting to be completed;

[0033] After the grafting is completed and the seedlings need to be loosened, the seedling clamping finger cylinder 2 is opened, so that the lower clamping jaws 3 are loosened and the grafted seedlings fall. At this time, the steel ball 9 is stuck in the second positioning hole 303, and the upper clamping jaw 6 should follow the lower clamping jaw 3 to open further, but at this time the upper clamping jaw 6 will be restricted by the micro-slider 5 connected to it, and the micro-slider 5 is blocked by the slide rail baffle 401 and cannot move further, so that the upper clamping jaw 6 cannot continue to open, but the steel ball 9 will be disengaged from the second positioning hole 303. Under the action of the tension spring 7, the two upper clamping jaws 6 are pulled closer, so that the steel ball 9 is stuck in the first positioning hole 302. At this time, the lower clamping jaw 3 is in the open state, and the upper clamping jaw 6 and the lower clamping jaw 3 are opened to the same extent. This state (the state of the upper clamping jaw 3 and the lower clamping jaw 6) is the initial state of the clamping jaw device, which is ready for continuing to clamp the seedlings.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
