Description

Technical Field

[0001] The invention belongs to the field of tree migration, and in particular relates to an adjustable large tree soil ball in-situ shaping and bundling device and a working method thereof. Background Art

[0002] With the acceleration of urbanization, urban landscaping has become increasingly important. Some scholars have calculated the ecological value of a tree, and a 50-year-old tree has a cumulative value of about $196,000. This shows that big trees can not only beautify and improve the environment, but also bring huge value. Therefore, the transplantation of big trees needs to be taken seriously.

[0003] Because the main part of the plant that absorbs water and nutrients is the root system, when transplanting seedlings, in order to protect the root system of the seedlings, it is necessary to dig up the soil around the original growth place of the seedlings together, so that when the seedlings are transplanted, the roots will be taken along with the original growth soil, and the seedling soil ball will come from this. Because the seedling soil ball is an important factor in determining whether the plant can survive, the soil ball must be tied before transplanting the plant to prevent the original growth soil from falling. The normal diameter of the soil ball is about 10 times the breast diameter of a large tree. For a large tree, the soil ball required is larger, and in the process of digging the soil ball, the excavator will dig a spherical deep trench around the large tree. The shape of the soil ball of a large tree is irregular, so the soil ball must be trimmed before tying it.

[0004] At present, there are few studies and applications on the mechanical shaping and mechanical bundling of soil balls. The shaping of soil balls is usually done manually. For small soil balls, only simple manual shaping is required, while for large soil balls, manual shaping is time-consuming and labor-intensive, and requires the help of machines. The bundling of soil balls is mainly divided into manual bundling and machine bundling. For small soil balls, bag bundling can be used, while for large soil balls, one part is to manually bundle the soil balls in situ, which is labor-intensive, inefficient, and requires at least two people to cooperate; the other part relies on existing mechanical bundling technology to bundle the soil balls, but it is not suitable for in-situ bundling of soil balls. Before bundling, the big tree needs to be placed on the bundling workbench, and it is lifted by a crane during the movement. The soil ball of the big tree will become loose, and the original soil will fall off, reducing the survival rate of the big tree after transplantation. Summary of the invention

[0020] The working method of the adjustable tree soil ball in-situ shaping and bundling device of the present invention is specifically as follows:

[0021] First, fix the two shaping modules on the two connecting rod modules, specifically, fix the shaping frame of the shaping module and the two connecting rods 5 of the connecting rod module; secondly, surround the trunk of the tree with the two detachable track modules and fix them together, so that the two semi-circular arc tracks form a complete circular track, and the support wheels of the cantilever support modules on each side are supported on the soil ball, and each support rod is placed on the trunk of the tree, and then tighten the hexagonal nut 1 on each support rod. According to the size of the soil ball, the total length of the telescopic cantilever and the cantilever frame is adjusted by adjusting the circular holes 1 at different positions on the cantilever frame and the telescopic cantilever, so that the shaping blades 1 and 2 of the two shaping modules fit the surface of the soil ball; then, the controller controls each drive motor 1 to rotate at the same speed 1, and each drive motor 1 drives the corresponding drive wheel to move along the upper surface of the circular guide through the corresponding gear set 1, and the drive wheel then drives the corresponding limit auxiliary wheel 1 and limit auxiliary wheel 2 to move along the lower surface and the inner arc surface of the circular guide respectively, thereby driving the same side The cantilever support module, retractable cantilever module, connecting rod module and shaping module make circular motion around the trunk of the tree; at the same time, the controller controls each driving motor 2 to reciprocate forward and reverse at the same speed 2, and the driving motor 2 drives the screw nut fixing plate to reciprocate up and down along the screw through the screw, and drives the corresponding shaping module to move along the surface of the soil ball according to the preset trajectory 1 through the two connecting rod modules on the same side; at the same time, the controller controls the driving motors 3 of the two shaping modules to rotate at the same speed 3, and each driving motor 3 drives the corresponding shaping blade 1 and shaping blade 2 to shape the soil ball.

[0022] After the shaping work is completed, the controller controls each drive motor 1, each drive motor 2 and each drive motor 3 to stop working; adjusts the total length of the telescopic cantilever and the cantilever frame to make the two shaping modules away from the surface of the soil ball, and removes the two shaping modules; then fixes the two end grass rope conveyors on the two connecting rod modules, specifically, fixes the end grass rope conveyors to the two connecting rods 5 of the connecting rod module; adjusts the total length of the telescopic cantilever and the cantilever frame again to make the output ends of the two end grass rope conveyors close to the soil ball; then passes the grass rope on the grass rope reel on each side through the pulley block and the end grass rope conveyor on the telescopic cantilever frame on the same side in turn, and fixes them on the soil ball. The controller controls each drive motor 1 to rotate at the same speed 4, and each drive motor 1 drives the corresponding drive wheel to move along the upper surface of the circular guide rail through the corresponding gear set 1, and the drive wheel then drives the corresponding limit auxiliary wheel 1 and limit auxiliary wheel 2 to move along the lower surface and the inner arc surface of the circular guide rail respectively, thereby driving the cantilever support module, the retractable cantilever module, the connecting rod module and the end straw rope conveyor on the same side to make circular motion around the trunk of the tree; at the same time, the controller controls each drive motor 2 to reciprocate forward and reverse at the same speed 5, and the drive motor 2 drives the screw nut fixing plate to reciprocate up and down along the screw through the screw, and through the two connecting rod modules on the same side.

After completing the bundling work, the controller controls each driving motor 1 and each driving motor 2 to stop working, and disassembles the two detachable track modules.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention adopts modular coordinated operation to solve the problems of large trees with different breast diameters, large differences in soil ball sizes, and loose soil balls caused by displacement and bundling of large tree soil balls; the present invention clamps large trees with different breast diameters by adjusting the elongated length of the support rod in the detachable track module, and can adjust the total length of the cantilever frame and the telescopic cantilever by connecting the cantilever frame in the cantilever support module and the circular holes at different positions on the telescopic cantilever in the telescopic cantilever module to adapt to the shaping and bundling of soil balls of different sizes. The present invention can perform shaping and bundling of the soil ball in situ. When the shaping module is fixed on the connecting rod module, the reciprocating motion of the connecting rod module drives the shaping module to shape the soil ball according to preset track one, so that the soil ball is flatter. When the terminal straw rope conveyor is fixed on the connecting rod module, the reciprocating motion of the connecting rod module drives the straw rope to bundle and cross-bundle the shaped soil ball in a circumferential direction according to preset track two and preset track three. During cross bundling, the straw rope can be bundled to the upper surface of the soil ball. The two bundling methods make the soil ball more secure. The connecting rod module adopts a double parallelogram mechanism with stable speed. The present invention realizes mechanized shaping and bundling of the soil ball through the connecting rod module, the shaping module and the terminal straw rope conveyor. The whole equipment does not need to be disassembled, and the operation is convenient and fast. There is no need to use a crane to shift the soil ball and manually shape and bundle the soil ball, so the soil ball is prevented from becoming loose when it is shifted, thereby improving the survival rate of large trees after transplanting, reducing labor and improving efficiency. The present invention realizes high efficiency and reliability of in-situ shaping and bundling of soil balls under different working conditions through multiple modules, and the modular design can shorten the manufacturing cycle of the present invention, save costs and facilitate maintenance.

[0025] 2. The cantilever support module of the present invention supports the entire device and is provided with a self-adjusting spring, which can float and self-adjust on the surface of the soil ball to ensure the stability and reliability of the entire device during operation.

[0026] 3. The present invention sets three pulleys so that the straw rope is in a tensioned state during the bundling work, ensuring that the straw rope can reach the required tightness when bundling the soil ball. BRIEF DESCRIPTION OF THE DRAWINGS
