If the cutting position is too high, the growth point of the seedling cannot be cut cleanly, affecting the growth consistency of the grafted seedling. If the cutting position is too low, the seedling's pith cavity will be cut, damaging the seedling's internal structure, which will seriously affect the seedling's survival rate and reduce grafting efficiency and quality. Therefore, those skilled in the art have provided a stem node adjustment device for cucurbit rootstock to solve the problems mentioned in the background art. Utility Model Content

[0019] The working principle of this utility model is as follows: First, the device is fixed by the positioning rod 30 and positioning screw 17 on the extension plate 18. The first plug 32 and the second plug 22 of the drive motor 1 are connected for power supply. The control switch 21 of the controller 23 on the support plate 24 is pressed, and the device enters the standby state. At this time, the servo adjustment module returns to the seedling origin. After the leaf expansion is adjusted, the stem node recognition camera 5 on the camera mounting bracket 4 on the left side of the fixed base 10 is started. At the same time, the two supplementary lights 26 on the back of the fixed base 10 are turned on to supplement the light. The stem node recognition camera 5 takes pictures of the rootstock stem nodes and transmits the stem node height data to the controller 23. After receiving the data, the controller 23 controls the hydraulic cylinder 16 on the left side of the fixed block 28 to move. The hydraulic cylinder 16 drives the hydraulic rod 15 to extend and retract. The hydraulic rod 15 drives the rotating seat 14, which in turn moves the gripper body 20 up and down through the positioning pin 13. At the same time, the drive air on the fixed plate 8... Cylinder 9 assists in adjusting the position of the fixing seat 10 to achieve precise adaptation of the rootstock stem node height. After the height adjustment is completed, controller 23 controls the solenoid valve 11 on the back of the gripper body 20 to supply air to the gripper cylinder 6 through the air pipe connector 12. The gripper cylinder 6 extends, driving the two gripper bodies 20 to close. The rubber protective pad 31 on the inner side of the gripper body 20 clamps the rootstock. If there is a deviation in the gripping position, it can be finely adjusted by the adjusting screw 29 on the side of the gripper body 20. Finally, after the gripping is completed, the gripper cylinder 6 retracts, the drive motor 1 starts, and its output end drives the rotating shaft 2, causing the fixing frame 3 and subsequent components to rotate 90 degrees clockwise. At the same time, the servo adjustment module returns to the seedling origin, transferring the rootstock to the cutting and bonding station of the main unit. After reaching the cutting and bonding station, the solenoid valve 11 controls the gripper cylinder 6 to exhaust air, the gripper body 20 opens to release the rootstock, and then the drive motor 1 drives the device to reset, preparing for the next cycle.
