[0002] In order to prevent trees from being blown down by the wind during their growth, they are supported when they are planted. Existing tree support devices mostly support the trees by fastening multiple wooden poles with nails, which is extremely troublesome to install.

[0003] The existing sapling clamping device is relatively easy to operate when clamping trees, but it still has the following shortcomings: 1. It adopts a clamping support method, and cannot detect the clamping force and automatically and accurately control the clamping pressure during clamping, and the clamping accuracy and automation are not ideal; 2. Since the diameter and height of the sapling gradually increase as it grows, the clamping width and height cannot be automatically changed according to the growth of the sapling during long-term clamping support, and it is easy to cause the clamping position to deform and be damaged when the tree grows due to untimely adjustment. Therefore, the utility model proposes a sapling support device to solve the above problems. Utility Model Content

[0006] As a further improvement of the utility model, it also includes a solar panel, a battery and an inverter connected in sequence, and the inverter is electrically connected to the drive motor and the PLC respectively.

[0007] As a further improvement of the utility model, a transverse guide rod is provided on the movable splint, a guide groove is provided at the end of the movable rod, and the guide rod is slidably connected in the guide groove.

[0008] As a further improvement of the utility model, a avoidance groove is provided at the other end of the moving rod, the avoidance groove is opposite to the screw rod, and the avoidance groove can accommodate the screw rod.

[0009] As a further improvement of the utility model, it also includes a support leg, an adjustment groove is opened on the upper part of the support leg, an adjustment rod is provided on the U-shaped support, the adjustment rod is slidably connected in the adjustment groove, and a tension spring is provided between the lower end of the adjustment rod and the bottom of the adjustment groove.

[0012] As a further improvement of the utility model, anti-slip pads are provided on the opposite surfaces of the fixed clamping plate and the movable clamping plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model drives the screw to rotate through the driving motor, so that the slider moves toward the tree, pushes the moving rod and the movable splint to move, and cooperates with the fixed splint to achieve the clamping operation. During the clamping process, the pressure sensor detects the clamping pressure. When the pressure reaches the lower limit, the pressure sensor sends a signal to the PLC, and the PLC controls the driving motor to stop working, thereby completing the clamping. Through the pressure sensor detection and PLC control, the clamping force can be accurately controlled to improve the clamping accuracy and automation. Since the moving rod and the slider are connected by a spring, the moving rod can be pushed into the tube body during the process of the tree becoming thicker, thereby changing the clamping spacing of the fixed splint and the movable splint to adapt to the growth of the tree and prevent the tree from being deformed or clamped. When the pressure detected by the pressure sensor reaches the upper limit, the pressure sensor sends a signal to the PLC, and the PLC controls the driving motor to reverse, driving the slider to move away from the tree to reduce the clamping force. When the pressure detected by the pressure sensor reaches the lower limit again, the driving motor is turned off by the PLC.

[0015] 2. Since the adjustment rod is slidably connected in the adjustment slot of the support leg, the U-shaped support is driven to move upward as the tree grows taller. The U-shaped support can be adaptively guided vertically and supported against tilting according to the growth of the sapling, thus avoiding scraping and pulling damage to the clamping position during the growth of the tree due to untimely adjustment.

[0022] It also includes a solar panel 7, a battery 8 and an inverter which are connected in sequence, and the inverter is electrically connected to a drive motor 10 and a PLC (9) respectively.

[0023] The solar panel 7 is arranged on the top of the tube body 3, and the battery 8, the inverter and the PLC (9) are all installed below the solar panel 7.

[0024] A transverse guide rod 6 is provided on the movable splint 2 , and a guide groove 18 is provided at the end of the movable rod 4 , and the guide rod 6 is slidably connected in the guide groove 18 .

[0025] The other end of the moving rod 4 is provided with an escape groove 19, which is opposite to the screw rod 12 and can accommodate the screw rod 12. When the moving rod 4 moves toward the screw rod 12, the screw rod 12 can extend into the escape groove 19.

[0026] The U-shaped support 1 also includes a leg 15, an upper portion of which is provided with an adjustment slot 20, an adjustment rod 14 is provided on the U-shaped support 1, the adjustment rod 14 is slidably connected in the adjustment slot 20, and a tension spring 16 is provided between the lower end of the adjustment rod 14 and the bottom of the adjustment slot 20. There are four sets of legs 15 and adjustment rods 14.

[0027] The lower end of the leg 15 is provided with an outer edge 22 , and the outer edge 22 is provided with an anchor rod through hole.

[0028] The opposite surfaces of the fixed clamping plate 17 and the movable clamping plate 2 are provided with anti-slip pads 21 .

[0029] The solar panel 7 converts solar energy into electrical energy and stores it in the battery 8, and uses the inverter to convert direct current into alternating current to power the PLC (9) and the drive motor 10.

[0030] When in use, the device of the utility model is placed outside the sapling so that the trunk of the sapling is located between the fixed clamping plate 17 and the movable clamping plate 2 and is close to the fixed clamping plate 17. The legs 15 are fixed to the ground using external anchor rods. The PLC (9) presets the lower limit and upper limit of the clamping pressure, and controls the operation of the drive motor 10 accordingly. During clamping, the PLC (9) controls the driving motor 10 to start forward so that it drives the screw rod 12 to rotate. The rotation of the screw rod 12 drives the slider 11 to move toward the sapling. The slider 11 pushes the movable rod 4 to move through the spring 13. The pressure sensor 5 drives the movable clamp 2 to move toward the sapling. After the movable clamp 2 cooperates with the fixed clamp 17 to clamp the sapling, the slider 11 that continues to move compresses the spring 13. The spring 13 in the compressed state elastically tightens the movable rod 4, the pressure sensor 5 and the movable clamp 2 toward the tree trunk. The pressure sensor 5 detects the squeezing force and transmits it to the PLC (9). When the pressure value reaches the preset lower limit value, the PLC (9) controls the driving motor 10 to turn off, thereby realizing automatic and accurate tightening, pressure control, clamping and support, improving the clamping accuracy and automation level, and saving time and labor.

[0031] As the sapling grows thicker, it will squeeze the movable clamp 2 outward, increasing the squeezing force on the pressure sensor 5. When the pressure value reaches the preset upper limit, the PLC (9) controls the drive motor 10 to start in the reverse direction, and the slider 11 moves away from the sapling and relaxes part of the pressure on the spring 13, so that the clamping pressure of the movable clamp 2 is reduced until the pressure detected by the pressure sensor 5 reaches the preset lower limit again, and the PLC (9) controls the drive motor 10 to turn off. By analogy, by real-time detection of the clamping support pressure and automatic adjustment, it is convenient to automatically and timely change the clamping spacing according to the growth of the sapling while ensuring the pressure control strength, so as to avoid the phenomenon that the clamping position is deformed and damaged when the tree grows due to untimely adjustment.

[0032] When the sapling grows taller, the fixed clamping plate 17 and the movable clamping plate 2 drive the U-shaped support 1 to move upward, and the U-shaped support 1 drives the adjustment rod 14 to move upward, and the tension spring 16 is stretched. The adjustment rod 14 slides in the leg 15 to play the role of vertical guidance and anti-tilt support for the U-shaped support 1 according to the growth of the sapling, avoiding the phenomenon of scraping and pulling damage to the clamping position when the tree grows due to untimely adjustment. The tension spring 16 plays a flexible fixing role on the adjustment rod 14 and the U-shaped support 1, ensuring uniform movement during the upward movement of the U-shaped support 1.
