Technical Field
[0001] This invention relates to the field of garden construction tools, specifically to an aid for quickly untying the root ball of a tree. Background Technology
[0002] When planting trees, the root ball is usually wrapped with materials such as straw rope or non-woven fabric to protect the integrity of the root system. However, it is necessary to untie it in time before planting, otherwise it will affect the root system's respiration, leading to poor growth or even root rot in the later stage. The existing untying method mainly relies on manual cutting of the wrapping material one by one with scissors or knives, or cutting it with simple cutting tools.
[0003] Manual cutting is extremely inefficient. It takes 5-10 minutes for a single person to process one root ball, and multiple people are needed to prevent the root ball from falling apart. Secondly, the root ball and root system are easily scratched and damaged during the operation, especially for planting soil with strong cohesion, which can easily cause the root ball to loosen when manually peeled.
[0004] Simple cutting tools, lacking precise positioning and guiding structures for root balls of different sizes, can scratch the root ball during cutting and fail to effectively peel off the wrapping material. Therefore, a quick unbinding aid for tree planting root balls is proposed to solve these problems. Summary of the Invention

[0012] Preferably, the guide ring groove in the guide assembly is opened inside the rotating groove, and the outer side of the movable ring is fixed with a guide ring block that is slidably connected to the guide ring groove.
[0013] Preferably, the adjusting groove in the adjusting positioning assembly is opened at the top of the fixed frame, and the top of the adjusting block is fixed with a positioning screw that passes through the adjusting groove, and the outer side of the positioning screw is threaded with a first butterfly nut.

[0023] like Figure 1-10 As shown, a quick unbinding aid for planting tree soil balls includes an outer ring 1 for installing a fixing structure 2. The outer ring 1 serves as the installation base and load-bearing frame of the entire aid. The fixing structure 2 can achieve precise positioning and clamping of the aid and the soil ball.
[0024] The outer ring body 1 is provided with a fixed handle 3 on the outside to provide a gripping fulcrum for the operator. The outer ring body 1 is provided with a drive structure 4 connected to the fixed structure 2 inside. The outer ring body 1 is connected to a movable handle 5 through the drive structure 4. The movable handle 5 provides power for the opening and closing of the fixed structure 2 through the drive structure 4, thereby realizing the opening and closing of the fixed structure 2.
[0025] The top of the outer ring 1 is provided with an adjustable cutting structure 6, which is used to achieve precise circular cutting of the packaged object and can be adapted to different sizes of soil balls. A locking structure 7 is provided between the fixed handle 3 and the movable handle 5, which can fix the relative position of the two handles after positioning and clamping, preventing the positioning from loosening during operation and ensuring operational stability.
[0026] like Figure 2-4As shown, in the preferred embodiment, the fixing structure 2 includes multiple rotating shafts 21, positioning arc rods 22, incomplete gears 23, and elastic peeling teeth 24.
[0027] Multiple rotating shafts 21 are rotatably connected to the inside of the outer ring body 1 and are evenly distributed in a circular array to ensure balanced positioning force on the soil ball. A positioning arc rod 22 extending to the inside of the outer ring body 1 is fixedly connected to the outside of the rotating shaft 21. The rotation of the rotating shaft 21 drives the positioning arc rod 22 to open and close, adapting to soil balls of different diameters.
[0028] An incomplete gear 23 is fixed on the outer side of one end of the positioning arc rod 22 inside the outer ring body 1. It serves as a power receiving component and cooperates with the drive structure 4. An elastic peeling tooth 24 is installed at the bottom of the other end of the positioning arc rod 22 away from the rotating shaft 21. It is used to insert into the inside of the wrapping material. At the same time, the elastic design can adapt to the uneven shape of the soil ball surface and avoid scratching the soil ball.
[0029] like Figure 2-4 As shown, in the preferred embodiment, the rotating ring 41 in the drive structure 4 is rotatably connected to the inside of the outer ring body 1, and multiple arc-shaped racks 42 are fixed on its inner side. The number and position of the arc-shaped racks 42 correspond one-to-one with the incomplete gears 23 in the fixed structure 2, and the two mesh with each other to form a power transmission link.
[0030] A connecting ring 43 extending to the outer side of the outer ring body 1 is fixedly connected to the outer side of the rotating ring 41. A driving ring 44 is fixedly provided on the outer side of the connecting ring 43. The driving ring 44 is sleeved on the outer side of the outer ring body 1. The movable handle 5 is fixedly installed on the outer side of the driving ring 44.
[0031] By rotating the movable handle 5, the operator can drive the drive ring 44, the connecting ring 43 and the rotating ring 41 to rotate synchronously. This, in turn, drives the incomplete gear 23 to rotate through the arc rack 42, and finally drives the positioning arc rod 22 to rotate around the rotating shaft 21, thus realizing the synchronous opening and closing of the positioning arc rod 22.
[0032] like Figure 7 As shown, in the preferred embodiment, a plurality of square holes 11 are provided on the inner side of the outer ring body 1. The number of square holes 11 is the same as that of the positioning arc rod 22. The positioning arc rod 22 is slidably connected to the inside of the square holes 11. The square holes 11 provide guidance and limit for the positioning arc rod 22, ensuring that its opening and closing trajectory is accurate and avoiding deviation.
[0033] A U-shaped frame 12 is fixed on the outer side of the outer ring body 1, and the connecting ring 43 is located inside the U-shaped frame 12. The U-shaped frame 12 can limit the rotation angle of the movable handle 5 to prevent the movable handle 5 from rotating too much, causing the arc rack 42 to disengage from the incomplete gear 23, or causing the positioning arc rod 22 to open and close excessively, resulting in damage to the components.
[0034] A U-shaped connecting block 13 is also fixed on the outer side of the outer ring body 1. The fixed handle 3 is securely connected to the outer ring body 1 through the U-shaped connecting block 13. The connecting ring 43 is located inside the U-shaped connecting block 13, which neither affects the rotation of the connecting ring 43 nor affects the stability of the fixed handle 3 installation.
[0035] like Figure 5-6 As shown, in the preferred embodiment, the adjustable cutting structure 6 is used to achieve precise circular cutting of the binding strap and can be adapted to different sizes of soil balls.
[0036] The adjustable cutting structure 6 has a rotating groove 61 on the top of the outer ring body 1. A movable ring 62 is rotatably connected inside the rotating groove 61. The movable ring 62 can rotate freely along the rotating groove 61, providing a motion basis for the ring cutting. A guide component 63 is provided on the outside of the movable ring 62 to ensure that the rotation process of the movable ring 62 is smooth and to avoid cutting deviation.
[0037] A fixed frame 64 is fixedly provided at the top of the movable ring 62. An adjusting block 65 is slidably connected inside the fixed frame 64. A ring-shaped cutting blade 66 is detachably connected to one end of the adjusting block 65 near the outer ring body 1. The adjusting block 65 can slide horizontally along the fixed frame 64, thereby adjusting the distance between the ring-shaped cutting blade 66 and the soil ball, which is convenient for cutting soil ball wrapping materials of different sizes.
[0038] The top of the adjusting block 65 is provided with an adjusting positioning component 67, which is used to lock and fix the adjusting block 65 after the adjustment position is determined, so as to prevent displacement during the cutting process.
[0039] To facilitate convenient replacement and secure installation of the annular cutting blade 66, a mounting bracket 651 is fixed at one end of the adjusting block 65 near the outer ring body 1. The annular cutting blade 66 is installed inside the mounting bracket 651 by bolts. The bolt connection not only ensures that the annular cutting blade 66 is securely installed and avoids shaking during cutting, but also allows for quick removal of the bolts to replace the annular cutting blade 66, facilitating maintenance and sharpening of the annular cutting blade 66. The blade of the annular cutting blade 66 is serrated, adaptable to the cutting needs of different materials such as straw rope, non-woven fabric, and plastic film.
[0040] In the preferred embodiment, the guide component 63 provides precise guidance and limit for the rotation of the movable ring 62. The guide ring groove 631 in the guide component 63 is opened on the inner side wall of the rotating groove 61. The outer side of the movable ring 62 is fixed with a guide ring block 632 that matches the guide ring groove 631. The guide ring block 632 slides into the guide ring groove 631 to form a nested mating structure.
[0041] The guide ring groove 631 and guide ring block 632 can limit the axial displacement of the movable ring 62, ensuring that the movable ring 62 only moves in a circle along the rotating groove 61, avoiding the movable ring 62 from shifting up and down or shaking during rotation, ensuring the accuracy of the cutting trajectory of the annular cutting blade 66, and improving the integrity of the strap cutting.
[0042] In the preferred embodiment, the adjusting positioning component 67 is used to lock and fix the position of the adjusting block 65 to ensure that the position of the adjusting block 65 and the annular cutting blade 66 is stable during the cutting process.
[0043] The adjustment groove 671 in the adjustment positioning component 67 is opened at the top of the fixed frame 64. The adjustment groove 671 is set along the length direction of the fixed frame 64 and is consistent with the sliding direction of the adjustment block 65. The top of the adjustment block 65 is fixed with a positioning screw 672. The positioning screw 672 passes through the adjustment groove 671 and extends to the top of the fixed frame 64. The outer side of the positioning screw 672 is threaded with a first butterfly nut 673.
[0044] The bottom diameter of the first butterfly nut 673 is larger than the width of the adjustment groove 671. After the adjustment block 65 slides to the target position, tighten the first butterfly nut 673. Its bottom can fit tightly against the top of the fixing frame 64 and lock the adjustment block 65 by friction to prevent it from sliding due to force during the cutting process. Loosening the first butterfly nut 673 allows the position of the adjustment block 65 to be adjusted again. The operation is convenient and adaptable to the cutting needs of soil balls of different diameters.
[0045] like Figure 7-8 As shown, in the preferred embodiment, the locking structure 7 is used to fix the relative position of the movable handle 5 and the fixed handle 3, so that the positioning arc rod 22 keeps the soil ball clamped, making it easier for the operator to focus on the cutting operation.
[0046] The arc-shaped locking frame 71 in the locking structure 7 is fixed to the outside of the movable handle 5. The arc of the arc-shaped locking frame 71 is adapted to the rotation trajectory of the movable handle 5. An arc-shaped locking block 72 is fixed to the outside of the fixed handle 3. The arc-shaped locking block 72 is slidably connected to the inside of the arc-shaped locking frame 71 to ensure that the arc-shaped locking frame 71 can slide synchronously along the outside of the arc-shaped locking block 72 when the movable handle 5 rotates, without affecting the positioning adjustment.
[0047] The top of the arc-shaped locking frame 71 is provided with a locking groove 73, which is set along the length of the arc-shaped locking frame 71. The top of the arc-shaped locking block 72 is fixed with a locking screw 74, which extends through the locking groove 73 to the top of the arc-shaped locking frame 71. The outer side of the locking screw 74 is threaded with a second butterfly nut 75, and the bottom diameter of the second butterfly nut 75 is larger than the width of the locking groove 73.
[0048] After the positioning and clamping are completed, tighten the second butterfly nut 75. When the second butterfly nut 75 abuts against the top of the arc-shaped locking frame 71, the arc-shaped locking block 72 can be locked in the arc-shaped locking frame 71 by friction, thereby fixing the relative position of the movable handle 5 and the fixed handle 3, preventing the positioning arc rod 22 from loosening and ensuring the stability of the operation.
[0049] like Figure 9-10As shown, in the preferred embodiment, the elastic peeling tooth 24 adopts an elastic telescopic structure design, which can effectively peel off the binding tape while protecting the integrity of the soil ball.
[0050] The elastic peeling tooth 24 includes two parts: an elastic part and a prismatic tooth block 244. The outer frame 241 in the elastic part is fixed to the bottom of the positioning arc rod 22. A lifting block 242 is slidably connected inside the outer frame 241. A spring 243 is also fixed inside the outer frame 241. One end of the spring 243 is fixedly connected to the top of the lifting block 242, and the other end is fixedly connected to the inner top wall of the outer frame 241, forming an elastic telescopic link.
[0051] The rhomboid toothed block 244 is fixed at the bottom of the lifting block 242. The rhomboid toothed block 244 is diamond-shaped, which makes it easy to insert between the wrapping material and the soil ball. When the surface of the soil ball is uneven, the rhomboid toothed block 244 can compress the spring 243 through the lifting block 242 and elastically expand and contract along the curvature of the soil ball, so that the rhomboid toothed block 244 always fits the surface of the soil ball and avoids rigid contact that scratches the soil ball.
[0052] like Figure 9-10 As shown in the preferred embodiment, to further protect the root system of the root ball, the tips of the rhomboid teeth 244 are designed to be blunt, which can prevent sharp tips from directly penetrating the root ball and damaging the root system. At the same time, tiny air vents are opened on the tips of the teeth, with the diameter of the tiny air vents set at 2mm. This diameter can prevent root ball particles from falling out of the holes, and after the elastic peeling teeth 24 come into contact with the root ball, a longitudinal air vent is formed. After watering after planting, the accumulated water can be quickly drained through the air vent, improving the air permeability of the root ball, providing a good growth environment for the root system, and further improving the survival rate of transplanted trees.
[0053] In the preferred embodiment, the annular cutting blade 66 is made of stainless steel, the prismatic toothed block 244 is made of rubber, and the rest of the structure can be made of high-strength engineering plastics. High-strength engineering plastics have excellent heat and cold resistance, excellent mechanical properties over a wide temperature range, are suitable for use as structural materials, have good corrosion resistance, are less affected by the environment, have good durability, are lightweight, have high specific strength, and have outstanding wear reduction and wear resistance, making it easy for workers to operate the auxiliary device.
[0054] In the preferred embodiment, the diameter of the circular shape formed by the multiple positioning arc rods 22 near the inner end is adjustable from 30 to 80 cm, which can better adapt to tree root balls of different sizes.
[0055] Working principle: The method of using this tree planting root ball quick untying aid is as follows: Diameter adjustment: Smoothly place the outer ring 1 on the outside of the soil ball, so that the elastic peeling teeth 24 face the soil ball binding surface. According to the actual specifications of the soil ball of the tree to be treated, loosen the second butterfly nut 75 of the locking structure 7, release the lock of the movable handle 5 and the fixed handle 3, and let the movable handle 5 rotate freely within the limited range. The operator holds the fixed handle 3 and the movable handle 5 with both hands respectively. Using the fixed handle 3 as the fulcrum, rotate the movable handle 5. Under the action of the drive ring 44, the connecting ring 43 and the rotating ring 41, the arc rack 42 drives the incomplete gear 23 to mesh and drive multiple positioning arc rods 22 to move synchronously towards the center of the soil ball along the square hole 11 of the outer ring 1 until the elastic peeling teeth 24 are attached to the surface of the soil ball and inserted into the gap between the wrapping material and the soil ball. Then tighten the second butterfly nut 75 to lock the arc locking block 72 in the arc locking frame 71, fix the relative position of the two handles, and keep the positioning arc rods 22 in a clamped state. Cutting the wrapping material: Loosen the first butterfly nut 673 on the adjusting positioning component 67 so that the adjusting block 65 can slide freely along the fixed frame 64, thereby driving the annular cutting blade 66 to move horizontally until the cutting blade is aligned with the target cutting position of the outer wrapping material of the soil ball. Then tighten the first butterfly nut 673 to prevent displacement during cutting. Next, slowly rotate the fixed frame 64 so that the annular cutting blade 66 makes a uniform circular motion around the soil ball to cut the wrapping material in an annular shape. Removal of wrapping material: After the wrapping material is cut in a ring, loosen the second butterfly nut 75, rotate the movable handle 5 in the opposite direction, and drive the positioning arc rod 22 to open outward in sync, separating it from the surface of the soil ball. At this time, the elastic peeling teeth 24 will tear the cut wrapping material apart as a whole and peel it off smoothly, effectively avoiding scratching the soil ball and damaging the root system. Breathing aid: After the wrapping material is removed, there is no need to remove the aid. Repeat the diameter adjustment operation to fix the aid on the surface of the soil ball. The tiny air pores of the 244 tips of the rhomboid teeth form a longitudinal air venting channel. After planting and watering, the accumulated water can be quickly drained through the air venting channel, improving the air permeability of the soil ball. Remove the auxiliary device: After the tree has been planted for 7-10 days and the root system has stabilized, repeat the process of peeling off the wrapping material to remove the auxiliary device from the soil ball.
