Description

Technical Field

[0001] This utility model relates to the field of fruit tree girdling, specifically to a variable-head jujube girdling device. Background Technology

[0002] Ringing refers to the practice of removing a certain width of bark around the branches of a plant. It is a planting measure to promote flower bud differentiation and improve fruit quality. Because the water and minerals absorbed by the roots are transported normally upward along the vascular bundles, after a period of time, the upper branches of the ringed branches grow normally. However, due to the obstruction of the downward transport of organic matter, a lot of organic matter accumulates at the upper end of the cut, thus forming swollen callus tissue or tumor-like material. The principle behind implementing girdling and girdling techniques on fruit trees is to temporarily hinder the transport of organic matter produced by photosynthesis to the underground parts, so that nutrients are concentrated on branches and buds, promoting flower bud formation, improving flower quality, and reducing flower and fruit drop; it also shortens the vegetative growth cycle of young trees, promotes early fruiting, and increases the yield of trees that are growing vigorously or have empty fruit. Currently, girdling is widely used in agriculture and horticulture. Girdling devices need to be compatible with different trunk thicknesses to cut different widths. However, the limited number of blades and the complex disassembly and assembly of the girdling blades often greatly reduce the efficiency of girdling workers. Utility Model Content

[0003] To solve the above-mentioned technical problems, a variable-head jujube ring-cutting device is provided. This technical solution solves the problem in the background art that the ring-cutting device often has a single number of blades and the method of disassembling and assembling the cutting blade is complicated, which greatly reduces the ring-cutting efficiency of the workers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a variable-head jujube ring-cutting device, comprising a third main body shell: a second rotating shaft is rotatably connected to the top of the third main body shell, a second limiting plate is slidably connected to the second rotating shaft, a rotating shell is rotatably connected to the top of the outer side of the second limiting plate, a sliding groove is provided inside the rotating shell, a slider that cooperates with the sliding groove is fixedly connected to the top of the outer side of the second limiting plate, a second main body shell is connected to the top of the third main body shell through a fixing frame, and the inner wall of the second main body shell is rotatably connected to the rotating shell through threads.

[0005] Preferably, a motor is installed at the bottom of the third main body shell, and the output end of the motor is fixedly connected to the second rotating shaft.

[0011] Preferably, a first main body shell is fixedly connected to one side of the third main body shell, and a handle is fixedly connected to one end of the first main body shell.

[0012] Compared with the prior art, this utility model provides a variable blade jujube ring-cutting device, which has the following beneficial effects: when it is necessary to load or unload the blades, the rotating shell is driven to rotate and rise by rotating the screw rod, thereby causing the second limiting plate to disengage from the rotating shaft to create space for loading and unloading the blades. After loading or unloading the blades, the screw rod is rotated in the opposite direction until the second limiting plate holds the blades. At the same time, the user can freely adjust the number of blades according to the thickness of the tree trunk. This design greatly simplifies the process of loading and unloading the blades and also improves the compatibility of the target users. Attached Figure Description

[0015] Example 1 Please refer to Figure 1 and Figure 2 As shown, a variable-head jujube ring-cutting device includes a third main body shell 5: a second rotating shaft 16 is rotatably connected to the top of the third main body shell 5, a second limiting plate 17 is slidably connected to the second rotating shaft 16, a rotating shell 20 is rotatably connected to the top of the outer side of the second limiting plate 17, a sliding groove 19 is provided inside the rotating shell 20, a slider 18 that cooperates with the sliding groove 19 is fixedly connected to the top of the outer side of the second limiting plate 17, a second main body shell 4 is connected to the top of the third main body shell 5 through a fixing frame 23, the inner wall of the second main body shell 4 is rotatably connected to the rotating shell 20 through threads, the rotating shell 20 is tightly fitted with the second limiting plate 17, a lubricating oil to reduce friction is provided at the contact position between the slider 18 and the sliding groove 19, and a screw rod 14 is fixedly connected to the top of the rotating shell 20; In this embodiment, by rotating the screw rod 14, the rotating shell 20 is driven to rotate and rise, thereby causing the second limiting plate 17 to slidably connect to the second rotating shaft 16, which provides space for loading and unloading the blade 13. After loading and unloading the blade, the screw rod 14 is rotated in the opposite direction until the second limiting plate 17 presses against the blade 13. When the device is in use, the second rotating shaft 16 rotates and drives the second limiting plate 17 to rotate. The slider 18 on the second limiting plate 17 and the sliding groove 19 opened in the rotating shell 20 cooperate with each other, so that the second limiting plate 17 can rotate relative to the rotating shell 20. Example 2 Please refer to Figure 2 and Figure 3As shown, a motor 12 is installed at the bottom of the third main body shell 5. The output end of the motor 12 is fixedly connected to the second rotating shaft 16. A first limiting plate 15 is fixedly connected to the bottom of the outer side of the second rotating shaft 16. A blade 13 is provided above the first limiting plate 15 and is slidably connected to the second rotating shaft 16. A limiting block 21 is fixed on the outer side of the second rotating shaft 16. The inner wall of the second limiting plate 17 and the inner wall of the blade 13 are both provided with limiting grooves 22 that cooperate with the limiting block 21. In this embodiment, by starting the motor 12, the output end of the motor 12 drives the second rotating shaft 16 to rotate, and the second rotating shaft 16 in turn drives the blade 13 to rotate, and at the same time drives the second limiting plate 17 to rotate. Example 3 Please refer to Figure 1 and Figure 4 As shown, the top of the third main body shell 5 is rotatably connected to the second clamp 11 and the first clamp 10 via the first rotating shaft 7. The second clamp 11 is fixedly connected to one side of the second clamp 11 and the first clamp 10 is fixedly connected to one side of the first clamp 10. A spring 6 is installed between the first clamp 8 and the second clamp 9. The inner surfaces of the first clamp 10 and the second clamp 11 are both smooth surfaces. In this embodiment, by pulling the angle between the first clamping rod 8 and the second clamping rod 9 outward, the spring 6 between the first clamping rod 8 and the second clamping rod 9 is in a stretched and taut state. At the same time, the angle between the second clamping foot 11 and the first clamping foot 10 will also increase to achieve the target width. After clamping, the first clamping rod 8 and the second clamping rod 9 are released, and the spring 6 converts the stretching potential energy into an inward pulling force to form a fixed structure. Example 4 Please refer to Figure 1 As shown, the first main body shell 3 is fixedly connected to one side of the third main body shell 5, and a handle 1 is fixedly connected to one end of the first main body shell 3. A switch button 2 is installed on the inner surface of the handle 1. A battery electrically connected to the switch button 2 is installed inside the first main body shell 3. The battery is electrically connected to the motor 12. In this embodiment, the battery inside the first main body shell 3 can be controlled by using the switch button 2, thereby controlling the operation of the motor 12; The working principle and usage process of this device are as follows: When it is necessary to load or unload the blade 13, the rotating housing 20 is rotated and raised by rotating the screw rod 14, thereby causing the second limiting plate 17 to disengage from the second rotating shaft 16 to create space for loading or unloading the blade 13. After loading or unloading the blade 13, the screw rod 14 is rotated in the opposite direction until the second limiting plate 17 holds the blade 13. At the same time, the user can freely adjust the number of blades 13 according to the thickness of the tree trunk. This design greatly simplifies the process of loading and unloading the blade 13 and also improves the compatibility of the user.
