[0016] 1. This application provides an adjustable jujube tree girdling device. Through a bidirectional screw, a first blade mounting plate, a second blade mounting plate, a positioning plate, a first blade, a second blade, and a limiting plate, when determining the width to be girdled, the rotating bidirectional screw drives the first and second blade mounting plates to slide synchronously towards the center of the bidirectional screw along the adjusting groove on the positioning plate. This causes the first and second blades to move closer together synchronously, so that a portion of the first blade overlaps with a portion of the second blade, making the width of the overlapped first and second blades the same as the width to be girdled. Then, the positioning plate is pushed to position the blades. The card plate, through its adjustable groove, causes the first blade mounting plate and the second blade mounting plate, which are slidably connected within the adjustable groove, to slide synchronously a specified distance toward the first electric telescopic rod. This causes the first blade, which is fixedly connected to one end of the first blade mounting plate, and the second blade, which is fixedly connected to one end of the second blade mounting plate, to slide a specified distance toward the limiting plate. This makes the distance between the first blade and the second blade and the limiting plate equal to the depth of girdling. This allows for easy adjustment of the distance between the two blades to perform girdling of different widths on the jujube tree as needed, and facilitates the limitation of the girdling depth, thus helping to prevent excessive girdling from damaging the tree.

[0017] 2. The adjustable jujube tree girdling device provided in this application comprises a first electric telescopic rod, a motor, a drive gear, a toothed groove assembly, a moving ring, a guide groove, a fixed plate, and a guide ring. During girdling, the first electric telescopic rod, through a limiting plate, drives the first and second blades mounted on it to slide towards the designated girdling position on the jujube tree and engage at the desired position. Then, the motor drives the drive gear fixedly connected to the output end to rotate. The rotating drive gear, through the meshing toothed groove assembly, drives the moving ring fixedly connected to the toothed groove assembly to rotate along the guide ring fixedly connected within the fixed plate under the constraint of the guide groove. The rotating moving ring drives multiple first positioning blocks, multiple limiting plates, multiple first blades, and multiple second blades mounted on it to rotate 360 ​​degrees along the jujube tree. During the rotation, the multiple first blades and multiple second blades quickly girdle the designated position on the jujube tree, facilitating girdling of tree trunks of different sizes and improving the efficiency of jujube tree girdling.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1-4As shown, this application provides an adjustable jujube tree girdling device, including a handle 1. One end of the handle 1 is fixedly connected to a fixed plate 2. A movable ring 3 is rotatably connected inside the fixed plate 2. Multiple first electric telescopic rods 5 are equidistantly distributed along the circumferential direction on the movable ring 3. One end of each first electric telescopic rod 5 is fixedly connected to a limiting plate 6. A second blade mounting plate 20 and a first blade mounting plate 19 are slidably connected to the limiting plate 6. A positioning plate 7 is slidably connected to the end of the limiting plate 6 facing the first electric telescopic rod 5. One end of each of the first blade mounting plate 19 and the second blade mounting plate 20 is connected through the positioning plate 7. A groove is formed at the position where the first blade mounting plate 19 and the second blade mounting plate 20 penetrate the positioning plate 7. An adjusting slide is provided, and a bidirectional screw 21 is rotatably connected within the adjusting slide. One end of the bidirectional screw 21 is connected through a limiting plate 6. One end of the first blade mounting plate 19 is fixedly connected to the first blade 22 by a nut. One end of the second blade mounting plate 20 is fixedly connected to the second blade 23 by a nut. One end of the first electric telescopic rod 5 is connected through a positioning plate 7. The positioning plate 7 is slidably connected to one end of the first electric telescopic rod 5. A fixing nut 17 is provided through the end of the positioning plate 7 facing the first electric telescopic rod 5. A fixing threaded hole 18 is provided at the connection position between the fixing nut 17 and the first electric telescopic rod 5. The number of fixing threaded holes 18 is multiple and equidistantly distributed at one end of the first electric telescopic rod 5.

[0029] In this embodiment, when determining the width to be girdled, the bidirectional screw 21 is rotated. The counterclockwise and clockwise spiral patterns on the rotating bidirectional screw 21 will rotate synchronously, thereby driving the first blade mounting plate 19 and the second blade mounting plate 20 connected to the bidirectional screw 21 to slide synchronously towards the middle of the bidirectional screw 21 along the adjusting groove on the positioning plate 7. This causes the first blade 22, which is fixed at one end of the first blade mounting plate 19, and the second blade 23, which is fixed at one end of the second blade mounting plate 20, to move closer to each other synchronously. This causes a portion of the first blade 22 to overlap with a portion of the second blade 23, so that the width of the overlapped first blade 22 and second blade 23 is the same as the width to be girdled. Then, the first electric telescopic rod 5 is moved... Pushing the positioning plate 7 upwards causes the first blade mounting plate 19 and the second blade mounting plate 20, which are slidably connected within the adjustment groove, to slide synchronously a specified distance toward the first electric telescopic rod 5. This causes the first blade 22, which is fixedly connected to one end of the first blade mounting plate 19, and the second blade 23, which is fixedly connected to one end of the second blade mounting plate 20, to slide a specified distance toward the limiting plate 6. This makes the distance between the first blade 22 and the second blade 23 and the limiting plate 6 equal to the depth of girdling. At this point, the fixing nut 17 is passed through the top of the positioning plate 7 and inserted into the fixing threaded hole 18 at a specified position at one end of the first electric telescopic rod 5, thus fixing the adjusted position of the positioning plate 7.

[0030] It should be noted that the first electric telescopic pole 5 is equipped with a brake, which helps to prevent the first electric telescopic pole 5 from automatically retracting inward when it is not powered.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the moving ring 3 is fixedly connected with first positioning blocks 4 at equal intervals, the number of which is equal to the number of first electric telescopic rods 5. The multiple first electric telescopic rods 5 are respectively connected through to the corresponding first positioning blocks 4. A guide ring 14 is fixed on the inner wall of the fixed plate 2 facing the moving ring 3. A guide groove 15 matching the guide ring 14 is opened on the outer wall of the moving ring 3 facing the fixed plate 2. The moving ring 3 is rotatably connected to the fixed plate 2 through the guide groove 15 and the guide ring 14. A toothed groove group 16 is opened along the circumferential direction at the end of the moving ring 3 near the first positioning block 4. A drive gear 10 is provided at one end of the fixed plate 2. The drive gear 10 is meshed with the toothed groove group 16. A motor 8 is fixedly connected to one end of the drive gear 10. A fixed arc plate 9 is provided at the end of the motor 8 facing the fixed plate 2. The fixed arc plate 9 is fixedly connected to the fixed plate 2. The motor 8 and the fixed arc plate 9 are interlocked.

[0032] In this embodiment, during girdling, the first electric telescopic rod 5 drives the first blade 22 and the second blade 23 mounted on it to slide towards the designated girdling position on the jujube tree through the limiting plate 6, and then locks into the designated girdling position. Then, the motor 8 drives the drive gear 10 fixedly connected to the output end to rotate. The rotating drive gear 10 will drive the moving ring 3 fixedly connected to the tooth groove group 16 through the meshing tooth groove group 16 to rotate along the guide ring 14 fixedly connected in the fixed plate 2 under the restriction of the guide groove 15. The rotating moving ring 3 will drive the multiple first positioning blocks 4, multiple limiting plates 6, multiple first blades 22 and multiple second blades 23 mounted on it to rotate 360 ​​degrees along the jujube tree. During the rotation, the multiple first blades 22 and multiple second blades 23 quickly girdle the designated position on the jujube tree.

[0033] It should be noted that the number of motors 8 and drive gears 10 is symmetrically distributed at both ends of the fixed plate 2. When the moving ring 3 separates from the drive gear 10 at one end of the fixed plate 2 during rotation, the drive gear 10 at the other end of the fixed plate 2 drives the moving ring 3 to continue rotating.

[0034] like Figure 1 and Figure 2 As shown, the fixed plate 2 is fixedly connected at equal intervals to the end away from the first positioning block 4 with a second positioning block 13 of the same number as the first positioning block 4. A second electric telescopic rod 11 is connected through the second positioning block 13. A clamping arc plate 12 is fixedly connected to one end of the second electric telescopic rod 11.

[0035] In this embodiment, before girdling, the second electric telescopic rod 11 drives the clamping arc plate 12 to extend onto the jujube tree and clamp onto the jujube tree, so that the device can clamp and position itself at the designated location on the jujube tree, preventing the device from shaking during the girdling process and affecting the girdling effect.

[0036] It should be noted that the second electric telescopic rod 11 is equipped with a brake, which helps to prevent the second electric telescopic rod 11 from automatically retracting inward when it is not powered.

[0037] Working principle:

[0038] When determining the width to be girdled, the bidirectional screw 21 is rotated. The counterclockwise and clockwise spiral grooves on the rotating bidirectional screw 21 will rotate synchronously, thereby driving the first blade mounting plate 19 and the second blade mounting plate 20 connected to the bidirectional screw 21 to slide synchronously towards the middle of the bidirectional screw 21 along the adjusting groove on the positioning plate 7. This causes the first blade 22, which is fixed at one end of the first blade mounting plate 19, and the second blade 23, which is fixed at one end of the second blade mounting plate 20, to move closer to each other synchronously, so that a part of the first blade 22 and the second blade 23 move closer together. Part of the blades 23 overlap, so that the width of the first blade 22 and the second blade 23 after overlap is the same as the width to be circumcised. Then, the positioning plate 7 is pushed onto the first electric telescopic rod 5. The positioning plate 7 will drive the first blade mounting plate 19 and the second blade mounting plate 20, which are slidably connected in the adjustment groove, to slide synchronously a specified distance in the direction of the first electric telescopic rod 5 through the adjustment groove. This will drive the first blade 22, which is fixedly connected to one end of the first blade mounting plate 19, and the second blade 23, which is fixedly connected to one end of the second blade mounting plate 20, to move closer to the limit. The plate 6 slides a specified distance in the direction of the limiting plate 6, so that the distance between the first blade 22 and the second blade 23 and the limiting plate 6 is equal to the depth of girdling. Then, the fixed plate 2 and the moving ring are clamped to the position to be girdled by the handle 1. The second electric telescopic rod 11 drives the clamping arc plate 12 to extend onto the jujube tree and clamp onto the jujube tree, so that the device can clamp and position itself at the specified position on the jujube tree. The first electric telescopic rod 5 drives the first blade 22 and the second blade 23 mounted on it to slide onto the specified position to be girdled on the jujube tree through the limiting plate 6 and clamp onto the position to be girdled. Then, the drive gear 10, which is fixedly connected to the output end, is driven by the motor 8 to rotate. The rotating drive gear 10 will drive the moving ring 3, which is fixedly connected to the tooth groove group 16, to rotate along the guide ring 14, which is fixedly connected to the fixed plate 2, under the restriction of the guide groove 15. The rotating moving ring 3 will drive the first positioning block 4, the limiting plate 6, the first blade 22 and the second blade 23 installed on it to rotate 360 ​​degrees along the jujube tree. During the rotation, the first blade 22 and the second blade 23 will perform girdling on the designated position of the jujube tree.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
