Description

Technical Field

[0001] This invention relates to the field of tree shaping technology, and more specifically, to a shaping frame and method for preventing strangulation damage to trees during growth. Background Technology

[0002] The strangulation method refers to the practice of binding thin iron wire tightly to appropriate branches of trees from winter pruning to before bud break. As the branches thicken and grow, the iron wire embeds itself into the branches, achieving a production effect similar to ring-barking. By controlling the trees through strangulation, young trees can bear fruit even in drought conditions, and trees in the early fruiting stage can grow and bear fruit simultaneously, allowing the tree to transition from excessive vegetative growth to high yield. It is an ideal production method.

[0003] In the current tree cultivation process, trees are strangled by binding them with thin wires. However, this method is not convenient, and as the branches grow thicker, the wires become embedded in the branches. Removing the wires can damage the tree because the newly grown parts are fragile. In addition, during the growth process, trees need to be supported by shaping frames to prevent them from growing out of place or tilting due to environmental factors. However, ordinary shaping frames have limited functionality, significant limitations, and low practicality.

[0004] Therefore, based on this, and drawing upon years of extensive design, development, and practical manufacturing experience in the relevant industry, the inventor has researched and improved upon existing structures and shortcomings, providing a shaping frame and method to prevent strangulation damage to trees. The aim is to achieve greater ease of operation, save time and manpower, improve strangulation efficiency, and reduce damage to trees; to straighten and shape trees, enhancing their aesthetics and ornamental value, and increasing their stability; and to adapt to different types of trees, thus broadening the scope of application.

At the same time, the telescopic inner rod extends the guide device to the branching point. By pressing the locking strip, the locking strip is engaged inside the locking groove. Slightly rotating the guide device causes the semi-circular block to rotate inside the support frame, thereby adjusting the rotation angle of the guide device. Subsequently, by rotating the fixing knob, the semi-circular block is locked, thereby controlling the growth angle of the tree branches, straightening and shaping the tree, improving its aesthetics and ornamental value, and enhancing its stability.

[0024] 3. This invention uses a rotating knob to rotate a screw, which in turn extends and retracts the fixing plate to support trees of different thicknesses. At the same time, by using snap-fit ​​blocks to snap into the snap-fit ​​holes at different heights, it supports and shapes branches of different heights of the tree, adapting to different types of trees, thus broadening the scope of application and improving the practicality of the device.

[0043] S1: Place the four straightening brackets 1 on the four sides of the tree respectively, and make the four straightening guard plates 21 face each other. Fix the base block 11 to the ground by fixing bolts 12.

[0044] S2: By rotating the rotary knob 23, the rotary screw 22 is rotated, and the fixed plate 24 is moved, so that the locking blade 26 is attached to the bark of the tree.

[0045] S3: According to the height of the tree branches, by pressing the snap-fit ​​block 34, the telescopic inner rod 31 is extended inside the sleeve pipe 13, thereby adjusting the height of the telescopic inner rod 31 so that the bottom frame 51 fits into the tree branches.

[0046] S4: By pressing the snap-fit ​​strip 528, the second arc-shaped block 521 is opened, so that the second arc-shaped block 521 and the first arc-shaped block 511 wrap around the branches of the tree that need to be shaped;

[0047] S5: Slightly rotate the guide device 5 to make the semicircular block 41 rotate inside the support frame 35, thereby adjusting the rotation angle of the guide device 5. Then, by rotating the fixing knob 45, the fixing friction plate 46 moves in opposite directions, thereby locking the semicircular block 41, thereby controlling the growth angle of the tree branches.

[0048] S6: Regularly observe the trees. By rotating the knob 23 in the opposite direction, the rotating screw 22 can be rotated, thereby removing the clamping blade 26 from the inside of the tree and completing the strangulation method.

[0049] The working principle of this invention is as follows: Four straightening supports 1 are placed on the four sides of the tree, and the four straightening guard plates 21 are positioned opposite each other to wrap the tree trunk. The base block 11 is fixed to the ground by the fixing bolt 12. By rotating the rotating knob 23, the rotating screw 22 is rotated, which pushes the fixing plate 24 to move. The clamping blade 26 adheres to the bark of the tree. As the branches thicken and grow, the clamping blade 26 is embedded in the branches, which is similar to the effect of ring peeling. The tree is observed regularly. After the process is completed, the rotating knob 23 can be rotated in the opposite direction to rotate the rotating screw 22, thereby removing the clamping blade 26 from the inside of the tree and completing the strangulation method of the tree.

[0050] The tree is straightened by a straightening rod 14 and a constriction device 2 to prevent it from growing at an angle or bending due to natural conditions. At the same time, the telescopic inner rod 31 is extended to extend the guide device 5 to the branch. By pressing the locking strip 528, the locking spring 527 is compressed, opening the second arc block 521 and placing the tree branch on the first protective plate 513 on the first arc block 511. By closing the second arc block 521, the locking strip 528 is locked inside the locking groove 516. The guide device 5 is slightly rotated to make the semicircular block 41 rotate inside the support frame 35, thereby adjusting the rotation angle of the guide device 5. Then, by rotating the fixing knob 45, the fixing friction plate 46 moves in opposite directions, thereby locking the semicircular block 41 and controlling the growth angle of the tree branch.

[0051] By rotating the knob 23, the rotating screw 22 is rotated, thereby extending and retracting the fixing plate 24 to fix and support trees of different thicknesses. At the same time, by pressing the locking blocks 34 at both ends, the return spring 33 is compressed. By pulling up the telescopic inner rod 31, the locking blocks 34 are locked into the locking holes 15 at different heights, thereby supporting and shaping the branches of the tree at different heights.

The method of using the shaping frame for preventing strangulation damage to trees according to claim 6, characterized in that: S1: Place the four straightening brackets (1) on the four sides of the tree respectively, and make the four straightening guards (21) face each other. Fix the base block (11) to the ground by fixing bolts (12); S2: By rotating the rotary knob (23), the rotating screw (22) is rotated, and the fixed plate (24) is moved, so that the locking blade (26) is attached to the bark of the tree; S3: According to the height of the tree branches, by pressing the snap-fit ​​block (34), the telescopic inner rod (31) is extended inside the sleeve pipe (13), thereby adjusting the height of the telescopic inner rod (31) so that the bottom frame (51) fits into the tree branches. S4: By pressing the snap-fit ​​strip (528), the second arc block (521) is opened, so that the second arc block (521) and the first arc block (511) wrap around the branches of the tree that need to be shaped; S5: Slightly rotate the guide device (5) to make the semicircular block (41) rotate inside the support frame (35), thereby adjusting the rotation angle of the guide device (5). Then, by rotating the fixing knob (45), the fixing friction plate (46) moves in opposite directions, thereby locking the semicircular block (41) and controlling the growth angle of the tree branches. S6: Observe the tree regularly. By rotating the rotating knob (23) in the opposite direction, the rotating screw (22) can be rotated, thereby removing the clamping blade (26) from the inside of the tree and completing the strangulation method for the tree.
