[0011] By adopting the above technical scheme, the rootstock seedlings cut by the first cutting component can enter the second docking blocks on the seedling conveyor belt respectively, and both can be transported simultaneously by the seedling conveyor belt. During the transportation of the seedling conveyor belt, the second docking blocks on the two seedling conveyor belts are moved to the side close to each other through the action of the first curved plate on the docking plate, thereby making the incisions of the rootstock seedlings close to each other. At the same time, when the second docking blocks on the two seedling conveyor belts are close to each other, the docking sensor can transmit an electrical signal to the docking console, and the docking console controls the first cylinder to drive the seedling cutting knife to cut the end of the rootstock seedling close to each other.

[0016] Optionally, a side of the sliding block close to the docking plate is configured to be arc-shaped.

[0017] By adopting the above technical solution, the arc-shaped contact surface of the slider can reduce the friction between the slider and the second arc-shaped plate when the slider moves with the second docking block, thereby improving the smoothness of the docking of the two sliders.

[0018] Optionally, a receiving plate for receiving the docked rootstock seedlings is provided at one end of the seedling conveyor belt away from the feeding plate, and the bonding mechanism includes plastic sealing tape arranged on the upper and lower sides of the receiving plate, a sealing roller for releasing glue is provided at one end of the plastic sealing tape, a second driving motor for driving the sealing roller to rotate is provided on the sealing roller, and a collecting roller is provided at the other end of the plastic sealing tape.

[0019] By adopting the above-mentioned technical scheme, when the docked rootstock seedlings fall onto the receiving plate, the bonding sensor can transmit an electrical signal to the bonding and pressing controller, thereby causing the bonding and pressing component to cut the plastic sealing tape on the upper and lower sides of the connection of the docked rootstock seedlings and press it tightly on the connection of the docking of the rootstock seedlings; when the bonding and pressing component completes the plastic sealing of the rootstock seedlings, the bonding and pressing controller transmits an electrical signal to the second drive motor, causing the second drive motor to drive the collecting roller and the sealing roller to rotate, so that the cut section of the plastic sealing tape is wound around the collecting roller.

[0020] Optionally, the gluing and pressing assembly includes two extrusion plates, the plastic sealing tape is located between the two extrusion plates, a second cylinder for driving the extrusion plates to move is provided on the extrusion plates, an opening knife for cutting the plastic sealing tape is provided outside the extrusion plates, the opening knife is provided with a notch for protecting grafted seedlings, the opening knife is arranged along the edge of the extrusion plates, a cutting block is fixedly connected to the opening knife, a third cylinder for driving the opening knife to move is fixedly connected to the cutting block, and an extrusion groove is provided on the extrusion plate.

[0021] By adopting the above technical scheme, when the bonding sensor transmits the electrical signal to the bonding pressure controller, the bonding pressure controller can enable the third cylinder to drive the two opening knives to move toward each other and cut the plastic tape. Then, the second cylinder will drive the two extrusion plates to move toward each other under the control of the bonding pressure controller. At the same time, since only the plastic tape at the notch is not cut, when the second cylinder controls the extrusion plate to move, the external force of the extrusion plate will cause the plastic tape at the notch to separate from the entire plastic tape and press it tightly at the connection of the rootstock seedling, and the staff can take out the bonded rootstock seedling.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

The above-mentioned mechanical operation can improve the work efficiency of seedling grafting, reduce the labor intensity of workers, and improve the quality of grafting and the stability of grafting;

[0024] 2. The two are transported simultaneously by the seedling conveyor belt. During the transportation process of the seedling conveyor belt, the second docking blocks on the two conveyor belts are moved to the side close to each other by the action of the first arc plate on the docking plate, so that the incisions of the rootstock seedlings are close to each other. At the same time, when the second docking blocks on the two seedling conveyor belts are close to each other, the docking sensor can transmit an electrical signal to the docking control console, and the docking control console controls the first cylinder to drive the seedling cutting knife to cut the rootstock seedlings at the ends close to each other. After the incision is completed and during the transportation process of the seedling conveyor belt, the second arc plate can be used to dock the rootstock seedlings at the incision of the seedlings, and the two can be made into a whole and transported along the seedling conveyor belt at the same time;

[0025] 3. The bonding sensor can transmit an electrical signal to the bonding and pressing controller, thereby causing the bonding and pressing component to cut the plastic sealing tape on the upper and lower sides of the connection of the docked rootstock seedlings and press it tightly on the connection of the docked rootstock seedlings. When the bonding and pressing component completes the plastic sealing of the rootstock seedlings, the bonding and pressing controller transmits an electrical signal to the second drive motor, causing the second drive motor to drive the collecting roller and the sealing roller to rotate, so that the cut section of the plastic sealing tape is wound around the collecting roller.

[0039] The cutting conveyor belt 32 and the feed plate 2 are arranged in a V shape, and the ends of the two closer to the ground are inclined toward each other, and the tip of one of the seedling knives 33 abuts against the inner wall of the feed trough 21, thereby starting the first drive motor 321, and the first drive motor 321 drives the seedling knife 33 to rotate along the cutting conveyor, and at the same time, the rootstock seedlings in the feed trough 21 can be cut and slide out of the feed trough 21 in sections.

[0040] Reference Figure 1 and Figure 3 Two seedling conveyor belts for conveying rootstock seedlings are provided between the two supporting frames 1, the supporting frame 1 is located at the end of the conveyor belt, the two seedling conveyor belts 4 are parallel to each other and are located at the same height, and the seedling conveyor belts 4 are provided with a docking assembly 5 for automatically docking the rootstock seedlings during transportation. The rootstock seedling sections cut by the first cutting assembly 3 can slide into the docking assembly 5 along the feeding trough 21. At the same time, in order to reduce the probability of deviation of the rootstock seedlings when sliding from the feeding trough 21 into the docking assembly 5, a guide tube 23 is fixedly connected to one end of the feeding trough 21 close to the docking assembly 5, and the guide tube 23 is connected to the feeding trough 21.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The docking assembly 5 includes first docking blocks 52 fixedly connected to the seedling conveyor belt 4 and evenly arranged along the seedling conveyor belt 4, and the first docking blocks 52 on the two seedling conveyor belts 4 are arranged opposite to each other. The first docking block 52 is provided with two parallel slide grooves 521 on the side away from the seedling conveyor belt 4, and a slide rod 523 is slidably connected in the slide groove 521, and the height of the slide rod 523 is flush with the groove of the slide groove 521, and a first spring 522 is fixedly connected between the slide rod 523 and the side wall of the slide groove 521 on the side away from the first docking block 52 opposite to itself, and a second docking block 53 is fixedly connected to the upper end of the slide rod 523, and the second docking block 53 is slidably connected to the first docking block 52 through the slide rod 523, and the second docking block 53 is slidably opened on the side of the second docking block 53 away from the first docking block 52 for carrying rootstock seedlings, and a slider 533 is slidably connected in the slider groove 531, and the height of the slider 533 is higher than the slider groove 531, and a second spring 532 is fixedly connected between the slider 533 and the side of the arc groove 531 away from the second docking block 53 opposite to itself. A docking plate 51 for bringing the first docking block 52 and the second docking block 53 closer to each other is fixedly connected at the upper end edge of the side where the two seedling conveyor belts 4 are away from each other, and a first curved plate 511 and a second curved plate 512 are fixedly connected at the side where the docking plates 51 on both sides of the seedling conveyor belts 4 are closer to each other, the first curved plate 511 and the second curved plate 512 are located at the same height, the first curved plate 511 and the second curved plate 512 are both placed above the seedling conveyor belt 4, and the second curved plate 512 is located above the first curved plate 511.

[0042] After the rootstock seedling falls into the arc groove 531 along the guide tube 23, it can be conveyed along the seedling conveyor belt 4. At the same time, when the first docking block 52 and the second docking block 53 are conveyed along the seedling conveyor belt 4, the second docking block 53 can slide along the slide groove 521 to the side where the two second docking blocks 53 are close to each other under the restriction of the arc protrusion of the first arc plate 511, and the two second docking blocks 53 are close to each other, thereby making the ends of the two rootstock seedlings close to each other. Figure 1 and Figure 6 At the same time, a second cutting assembly 6 for cutting the joint of two rootstock seedlings is provided above the seedling conveyor belt 4. The second cutting assembly 6 includes a bracket 63 fixedly connected to the edge of the two seedling conveyor belts 4 away from each other. A connecting rod 64 is fixedly connected between the two brackets 63. The upper end of the connecting rod 64 is fixedly connected to a first cylinder 61. The push rod of the first cylinder 61 passes through the connecting rod 64 and is fixedly connected to a seedling cutting knife 62 for cutting the rootstock seedlings. In order to facilitate the docking between the two rootstock seedlings after the rootstock seedlings are cut, there is a 30° inclination between the seedling cutting knife and the conveying direction of the seedling conveyor belt 4. The connecting rod 64 is fixedly connected to a docking sensor 65 for detecting the docking of the second docking block 53 toward one side of the conveyor belt. The second cutting assembly 6 includes a docking controller for controlling the operation of the first cylinder 61. The docking controller is not drawn in the figure. The docking controller is electrically connected to the docking sensor 65 and the first cylinder 61. When the two opposite second docking blocks 53 below the second cutting assembly 6 are docked, the docking sensor 65 can transmit an electrical signal to the docking controller, so that the docking controller controls the first cylinder 61, and the first cylinder 61 drives the seedling cutting knife 62 to cut the ends of the rootstock seedlings on the second docking blocks 53 that are close to each other.

[0043] After the second cutting assembly 6 cuts the rootstock seedling, Figure 3 and Figure 4 After the two second docking blocks 53 on the two seedling conveyor belts 4 are docked, they will move together along the conveying direction of the seedling conveyor belt 4 away from the side of the support frame 1. The second curved plate 512 and the slider 533 are at the same height. When the slider 533 passes through the curved protrusion of the second curved plate 512, the sliders 533 on both sides move toward each other under the abutment of the second curved plate 512, thereby causing the sliders 533 to push the rootstock seedlings in the arc groove 531 closer to each other and make their incisions press against each other, so that the two rootstock seedlings are plugged together and transported together to the end of the seedling conveyor belt 4 away from the support frame 1. In order to improve the smoothness of the docking of the two sliders 533, the side of the slider 533 close to the docking plate 51 is set to an arc shape.

[0044] Reference Figure 1 and Figure 7The end of the seedling conveyor belt 4 away from the feed plate 2 is provided with a receiving plate 7 for receiving the docked rootstock seedlings. The receiving plate 7 includes a connecting plate 71 fixedly connected to the side walls of the two ends of the seedling conveyor belts 4. The end of the connecting plate 71 away from the seedling conveyor belt 4 is inclined toward the ground and is fixedly connected with two blocking plates 72 for limiting the movement of the rootstock seedlings. A gap is left between the two blocking plates 72. The end of the blocking plate 72 away from the connecting plate 71 is bent toward the side away from the ground and is in an arc shape. The docked rootstock seedlings conveyed by the seedling conveyor belt 4 can roll onto the blocking plate 72 through the connecting plate 71.

[0045] The side of the seedling conveyor belt 4 away from the feed plate 2 is used for bonding the bonding mechanism 8 at the joint of two rootstock seedlings. The bonding mechanism 8 includes a plastic sealing tape 83 and a sealing frame 81 arranged on the upper and lower sides of the receiving plate 7. The plastic sealing tapes 83 on the upper and lower sides are arranged in parallel. One end of the plastic sealing tape 83 is connected to a sealing roller 88 for placing glue, and the other end of the plastic sealing tape 83 is connected to a collecting roller 89. The collecting roller 89 and the sealing roller 88 are both erected on the ground through the sealing frame 81. The sealing roller 88 is provided with a second drive motor 86 for driving the sealing roller 88 to rotate.

[0046] Reference Figure 7 and Figure 8 , mounting blocks 812 are provided on the upper and lower sides of the plastic sealing tape 83, and the mounting blocks 812 are also located on the upper and lower sides of the gap between the two blocking plates 72. A column 811 for connecting the two mounting blocks 812 is fixedly connected, and the bonding mechanism 8 also includes a bonding and pressing component 82 for cutting the plastic sealing tape 83 and bonding the plastic sealing tape 83 to the joint of the rootstock seedling. The bonding and pressing component 82 includes a second cylinder 821 fixedly connected to the mounting block 812, and the second cylinder 821 is located at the center of the side where the two mounting blocks 812 are close to each other. The end of the push rod of the second cylinder 821 is fixedly connected with an extrusion plate 823, and the extrusion plate 823 is provided with an extrusion groove 8231 for pressing the plastic sealing tape 83 on the side away from the second cylinder 821. An opening knife 84 for cutting the plastic sealing tape 83 is arranged around the extrusion plate 823. The opening knife 84 is arranged in a square frame shape around the outer side wall of the extrusion plate 823. The extrusion plate 823 can slide up and down relative to the opening knife 84. In order to protect the rootstock seedling, the opening knife 84 is provided with a notch connected to the extrusion groove 8231. A notch block 85 is fixedly connected to the side wall of the opening knife 84 and the notch block 85 is located on the two side walls adjacent to the notch. A third cylinder 822 for driving the opening knife 84 to cut the plastic sealing tape 83 is installed between the notch block 85 and the mounting block 812.

[0047] Reference Figure 7 , Figure 8 , Fig. 9 and Fig.10The bonding mechanism 8 also includes a bonding sensor 87 for sensing the position of the rootstock seedling and a bonding pressure controller electrically connected to the bonding sensor 87. The bonding pressure controller is not shown in the figure. The bonding sensor 87 is fixedly connected to the side wall of the conveyor frame 41. The bonding pressure controller is electrically connected to the second drive motor 86, the second cylinder 821 and the third cylinder 822. When the rootstock seedling falls on the blocking plate 72, the bonding sensor 87 can transmit an electrical signal to the bonding pressure controller, and then the bonding pressure controller transmits an electrical signal to the third cylinder 822 to drive the opening knife 84 to move to the side of the plastic sealing tape 83 and to seal the plastic sealing tape during the movement. The tape 83 is cut, and then the pressure controller sends an electrical signal to the second cylinder 821, so that the second cylinder 821 drives the extrusion plate 823 to move and push toward the side of the rootstock seedling. At the same time, the extrusion plate 823 will press the cut plastic sealing tape 83 at the docking position of the two rootstock seedlings during the movement toward the side of the rootstock seedling, and press the plastic sealing tape 83 on both sides of the rootstock seedlings against each other. Then the pressure controller controls the second cylinder 821 and the third cylinder 822 to reset, and at the same time sends an electrical signal to the second drive motor 86 to rotate the second drive motor 86, so that the cut part of the plastic sealing tape 83 is rolled into the collecting roller 89.

[0048] The implementation principle of the embodiment of the present application is: when two rootstock seedlings are grafted, the first drive motor 321 is started, and the branches are placed in the feed troughs 21 on both sides of the seedling conveyor belt 4 at the same time, and the branches are cut into multiple rootstock seedling segments by the first cutting component 3, and then the rootstock seedlings cut into segments are conveyed by the seedling conveyor belt 4, and during transportation, the two are brought close to each other by the first curved plate 511 in the docking component 5 to align the ends of the rootstock seedlings, and then the second cutting component 6 is used to make an oblique incision on the ends to be docked, and then the second curved plate 512 in the docking component 5 is used to dock the two rootstock seedling incisions, thereby completing the docking of the two during the transmission of the rootstock seedlings, and then the rootstock seedlings are transported to the bonding mechanism 8 by the seedling conveyor belt 4, and then the first cylinder 61 and the second cylinder 821 are operated under the induction of the bonding sensor 87 and the control of the bonding pressure controller to bond and fix the incisions of the two, thereby quickly completing the grafting of the seedlings.
