Description

Technical Field

[0001] This invention relates to the field of seedling transplanting equipment technology, specifically an integrated equipment for digging up and transplanting roots of trees. Background Technology

[0002] In the transplanting of trees by digging up roots, hawthorn trees are characterized by relatively shallow root systems, well-developed lateral roots but weak taproots, and small overall volume. When transplanting hawthorn trees and similar seedlings, the root system is pruned to promote the growth of new fibrous roots from lateral roots, increase the absorption area of ​​water and nutrients, and improve the survival rate of the trees. After transplanting, the root environment is improved with a breathable substrate, and water and fertilizer are precisely regulated to achieve controllable root damage and efficient functional recovery. During this process, it is also necessary to avoid the root ball being too large, which could cause the roots to curl and entangle during subsequent planting.

[0003] An existing patent application (CN202310219103.6) discloses a forestry seedling transplanting device. This patent document describes a method using multiple combined shovels to excavate and lift tree roots for transplanting. Specifically, in transplanting mode, the transplanting mechanism is raised upwards under the control of a rotary motor and offset from the transplanting mechanism to avoid affecting its rotation. After the state is set, the bottom of the shovel contacts the ground under the drive of a lifting screw. After the bottom of the shovel contacts the ground, the angle adjustment push rod... The digging shovels in multiple transplanting mechanisms are synchronously retracted to a set angle. After the digging shovels are retracted, they are synchronously excavated into the ground under the action of hydraulic push rods. When the hydraulic push rods cause the digging shovels to excavate to a specified depth, the driven gear ring is driven by the transmission shaft and rotates under the action of the hydraulic push rods. After the rotation is completed, the clamping arm moves closer to the tree and completes the clamping operation of the tree through the clamping mechanism. After the clamping is completed, the lifting screw drives the pressure table to rise, and the load equipment drives the device to transfer and place the transplanted tree into the transplanting hole.

[0004] However, when using the technical solutions in the aforementioned patent documents, the clamping mechanism and the digging shovel on the transplanting mechanism work together to envelop the root ball on the outside of the tree root system, thereby achieving the overall digging and lifting of the tree. When transplanting hawthorn trees and similar seedlings in this way, the roots cannot be effectively pruned due to the obstruction of the digging shovel's own structure. Therefore, it is necessary to release the tree onto a net or the ground, and after pruning, perform a second clamping and lifting before finally planting the tree in the designated location. The overall operation is cumbersome, the equipment has poor continuity of operation, and the types of tree species it can adapt to are relatively limited. Therefore, this application provides an integrated tree root digging and transplanting device. Summary of the Invention

[0005] To address the shortcomings of the existing technology, the present invention aims to provide an integrated tree root digging and transplanting device. This device is suitable for transplanting hawthorn trees and seedlings with similar root system characteristics. During the transplanting process, it facilitates pruning of the seedling root area, controls the volume of the soil ball, optimizes the root structure, and overcomes the risk of seedlings falling over due to the upward shift of the center of gravity during transplantation caused by the small soil ball volume, thus ensuring the smooth and stable operation of the entire tree transplanting process.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows:

[0007] An integrated tree root digging and transplanting device is provided, including an L-shaped base, a positioning base, a docking execution arm, and multiple digging modules. The L-shaped base is detachably connected to the excavator arm, and the L-shaped base is connected to the docking execution arm through the positioning base. The multiple digging modules are slidably installed on the inner side of the docking execution arm. Each digging module includes a shovel body, and an arc-shaped groove is provided on the outer side of the shovel body. The arc-shaped groove is engaged and slidably connected with an arc-shaped slider on the docking execution arm. A flexible anti-damage clamp is provided on the shovel body, which can abut against the outer surface of the tree branches.

[0008] In this application, for the connection method between the L-shaped seat and the positioning base, one optional technical solution is: the positioning base is directly fixedly installed on the bottom side of the L-shaped seat.

[0009] In this application, another optional technical solution for the connection between the L-shaped seat and the positioning base is as follows: the L-shaped seat is connected to the positioning base through a travel limit stake, the travel limit stake and the L-shaped seat are detachably fixedly connected, and the travel limit stake and the positioning base are slidably connected by insertion; the positioning base is provided with a circular hole, the travel limit stake passes through the circular hole from top to bottom and extends downwards from the circular hole, the diameter of the circular hole is larger than the diameter of the travel limit stake, a limit plate is provided at the bottom of the travel limit stake, the upper side of the limit plate abuts against the lower side of the positioning base, the diameter of the limit plate is larger than the diameter of the circular hole; multiple columns are fixedly installed on the positioning base, and tension springs are installed between the travel limit stake and the multiple columns respectively.

[0010] Furthermore, a guide rail arm is fixedly installed at the end of the positioning base, and two docking execution arms are provided. Both docking execution arms are slidably connected to the guide rail arm. Multiple digging modules are divided into two groups corresponding to the two docking execution arms. The two docking execution arms move relative to each other, leaving an opening that matches the diameter of the sapling trunk, so that multiple digging modules can stably act on the outside of the sapling.

[0011] Furthermore, multiple columns are fixedly installed on the positioning base, and linear electric cylinders I are rotatably installed on two columns near the guide arm. The movable end of the linear electric cylinder I is rotatably connected to the support column.

[0012] In this application, for the sliding drive method of the digging module on the inner side of the docking execution arm, an optional technical solution is as follows: the upper side of the docking execution arm is connected to a drive seat through a support column, a linear electric cylinder II is rotatably installed at the bottom of the drive seat, a U-shaped drive control seat is fixedly installed on the movable end of the linear electric cylinder II, and the U-shaped drive control seat is rotatably connected to the cross pins on both sides of the shovel body.

[0013] In this application, another optional technical solution for the sliding drive method of the digging module on the inner side of the docking execution arm is: the inner side of the docking execution arm is equipped with a rotating wheel and a motor for driving the rotating wheel, and the rotating wheel is connected to the outer side of the shovel body through friction transmission.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The integrated tree root digging and transplanting equipment of this invention controls the digging module to move downward along a spherical trajectory on the inner side of the docking execution arm. During the movement of the digging module, the shovel body is inserted deep into the ground, using the shovel body to separate the soil clump corresponding to its inner position from the ground soil layer. Under the combined action of multiple digging modules, the contact area between the soil attached to the outer periphery of the tree roots and the ground soil layer is reduced, achieving effective separation of the tree roots from the ground soil layer. Since the movement trajectory of the digging module is along a spherical trajectory, the horizontal rigid compression of the soil layer caused by the traditional straight shovel blade being inserted into the ground at a 45-degree downward tilt is reduced, thus reducing mechanical damage to the tree roots.

[0016] 2. The integrated tree root digging and transplanting equipment of this invention utilizes a flexible, damage-resistant clamp at the top of the shovel to hold the outer side of the tree branches and trunks, exposing the root system area for pruning. During tree transportation, the equipment continuously holds and supports the tree branches and trunks and roots, eliminating the need to place them on the ground or in a net for root pruning. This provides excellent operational convenience, eliminates the need for secondary clamping of the trees, and ensures high continuity of equipment use. Furthermore, when transplanting hawthorn trees and similar seedlings with small root volumes, the clamping of the outer side of the tree branches and trunks effectively overcomes the risk of the seedlings falling over due to the small soil ball causing the center of gravity to shift upwards during transfer, ensuring a smooth and stable tree transplanting process.

[0017] 3. The integrated tree root digging and transplanting equipment of this invention uses flexible anti-damage clamps on the top of multiple shovels to support the tree branches and trunks. Since multiple digging modules can simultaneously retract and remain in the upward position, the L-shaped seat, positioning base, docking execution arm and multiple digging modules can move upward synchronously. Support is applied to the outside of the tree branches and trunks at a higher position, and operation space is reserved at a lower position for compacting the soil. The soil is covered by layered backfilling and compacted layer by layer with mechanical hammer to ensure that the verticality of the tree trunk and the degree of soil compaction meet the relevant technical specifications.

[0018] 4. In the integrated tree root digging and transplanting equipment of this invention, when multiple digging modules are closed downwards, the inclined structure I at the bottom of adjacent shovels abuts against each other, completely separating the tree roots from the original substrate; when multiple digging modules are closed upwards, the inclined structure II at the top of adjacent shovels abuts against each other, fully clamping various positions on the outer periphery of the tree and exposing the tree root area so that the tree roots can be manually pruned and treated with chemicals after pruning, which promotes the growth of new fibrous roots from lateral roots while ensuring the stable recovery of root damage.

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Furthermore, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] Example 1:

[0039] like Figure 1 As shown, this embodiment provides an integrated tree root digging and transplanting device, including an L-shaped base 11, a positioning base 13, a docking execution arm 21, and multiple digging modules 3. The L-shaped base 11 is detachably connected to the excavator arm, and the L-shaped base 11 is connected to the docking execution arm 21 through the positioning base 13. The multiple digging modules 3 are slidably installed on the inner side of the docking execution arm 21. The digging module 3 includes a shovel body 31, and an arc-shaped groove 32 is provided on the outer side of the shovel body 31. The arc-shaped groove 32 is engaged and slidably connected with the arc-shaped slider 24 on the docking execution arm 21. A flexible anti-damage clamp 34 is provided on the shovel body 31, and the flexible anti-damage clamp 34 can abut against the outer side of the tree branches.

[0040] To increase the clamping stability of the flexible anti-damage clamp 34 on trees, such as Figure 9 As shown, the upper end of the shovel body 31 is integrally formed with a widened end 311, and the flexible anti-damage clamp 34 is disposed on the top of the widened end 311. By increasing the top area of ​​the flexible anti-damage clamp 34, the clamping stability of the flexible anti-damage clamp 34 on the trees is increased.

[0041] In addition, rubber or silicone pads are wrapped and installed on the outer side of the trees in the area corresponding to the flexible anti-damage clamp 34. The contact stress is dispersed through elastic deformation, so that the pressure is evenly distributed in the padding medium, effectively avoiding mechanical damage to the bark due to local stress concentration.

[0042] The specific details of using the integrated tree root digging and transplanting equipment of this application are as follows:

[0043] I. Preparations before use;

[0044] Based on the tree type and root system size, select positioning bases 13, docking execution arms 21 and shovel bodies 31 of different specifications; check the smoothness of movement of each digging module 3 inside the docking execution arm 21 to ensure that the movement of multiple digging modules 3 is smooth and stable.

[0045] Second, excavation work, which involves digging the trees out of their original planting locations;

[0046] The control shovel module 3 extends downward along a spherical trajectory inside the docking execution arm 21. During the movement of the shovel module 3, the shovel body 31 is inserted deep into the ground, and the shovel body 31 is used to separate the soil clump corresponding to its inner position from the ground soil layer. Under the joint action of multiple shovel modules 3, the contact area between the soil attached to the outer periphery of the tree roots and the ground soil layer is reduced, and the tree roots are effectively separated from the ground soil layer.

[0047] III. Timber transportation and root pruning operations;

[0048] The boom of the excavator is raised, and the excavator is moved to an open area to carry out timber transport operations. Then, the digging module 3 of the control unit moves upwards and retracts along a spherical trajectory inside the docking arm 21, while the remaining digging modules 3 remain extended downwards, lifting the soil clumps at the base of the trees. For example... Figure 1 As shown, the multiple shovel modules 3 that move upward and retract are selected at intervals. The flexible anti-damage clamps 34 on the top of the shovel body 31 are used to clamp the outer side of the tree branches and trunks, exposing the root system area of ​​the trees for pruning.

[0049] IV. Planting operations: Plant the trees in the designated locations;

[0050] The mobile excavator transports the trees to the planting area; all the digging modules 3 are controlled to move upward and retract along the spherical trajectory inside the docking execution arm 21, and the flexible anti-damage clamps 34 on the top of multiple shovels 31 are used to stably clamp the outer side of the tree branches and trunks, exposing all the tree roots. The excavator arm is controlled to move, driving the L-shaped seat 11, positioning base 13, docking execution arm 21 and multiple digging modules 3 to move downward synchronously. After the soil clump at the bottom of the tree is completely inserted into the pit at the planting site, the soil on the upper side of the tree roots is compacted to complete the tree planting operation.

[0051] In step two above, the movement trajectory of the shovel module 3 is along a spherical trajectory, which reduces the horizontal rigid compression of the soil layer when the traditional straight shovel blade is inserted into the ground at a downward 45-degree angle, and reduces mechanical damage to the tree roots.

[0052] In step three above, during the timber transportation process, the equipment continuously clamps and supports the branches and roots of the trees, eliminating the need to place them on the ground or in nets for root pruning. This ensures ease of operation, eliminates the need for secondary clamping of the trees, and provides high continuity of equipment use. Furthermore, when transplanting hawthorn trees and similar seedlings with small root systems, clamping the outer side of the branches and trunks effectively overcomes the risk of the seedlings falling over due to the small size of the soil ball shifting the center of gravity upwards during transfer, ensuring a smooth and stable timber transplanting process.

[0053] In step four above, the flexible anti-damage clamps 34 on the top of multiple shovels 31 are used to support the tree branches and trunks. Since multiple shovel modules 3 can simultaneously retract and remain in the upward position, the L-shaped seat 11, positioning base 13, docking execution arm 21 and multiple shovel modules 3 can move upward synchronously. Support is applied to the outside of the tree branches and trunks at a higher position, and space is reserved at a lower position for compacting the soil. The soil is covered by layered backfilling and compacted layer by layer with mechanical hammer to ensure that the verticality of the tree trunk and the degree of soil compaction meet the relevant technical specifications.

[0054] To enhance the stable operation of the digging module 3 during the tree excavation, tree transfer, and root pruning stages, such as... Figure 7 and Figure 8 As shown, the bottom and top sides of the shovel body 31 are respectively provided with inclined structure I and inclined structure II; when multiple shovel modules 3 are closed downwards, the inclined structure I at the bottom of adjacent shovel bodies 31 abuts against each other, completely separating the tree roots from the original substrate; when multiple shovel modules 3 are closed upwards, the inclined structure II at the top of adjacent shovel bodies 31 abuts against each other, fully clamping various positions on the outer periphery of the tree and exposing the tree root area, so that the tree roots can be pruned manually and the pruning agent can be applied after pruning, which promotes the division of lateral roots into new fibrous roots while ensuring the stable recovery of root damage.

[0055] In this embodiment, the positioning base 13 is directly fixedly installed on the bottom lower side of the L-shaped base 11, and the docking execution arm 21 is detachably fixedly installed on the positioning base 13.

[0056] In this embodiment, the rotation drive method for the shovel body 31 inside the docking execution arm 21 is as follows: a rotating wheel and a motor for driving the rotating wheel are installed on the inner side of the docking execution arm 21. The rotating wheel is connected to the outer side of the shovel body 31 through friction transmission. The motor is started to control the rotating wheel to rotate. The friction transmission between the rotating wheel and the outer side of the shovel body 31 drives the shovel body 31 to rotate inside the docking execution arm 21.

[0057] Example 2:

[0058] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, a guide rail arm 14 is fixedly installed at the end of the positioning base 13, and two docking execution arms 21 are provided. Both docking execution arms 21 are fitted and slidably connected with the guide rail arm 14. The multiple digging modules 3 are divided into two groups corresponding to the two docking execution arms 21. The two docking execution arms 21 move relative to each other, leaving an opening that matches the diameter of the sapling trunk, so that the multiple digging modules 3 can stably act on the outside of the sapling.

[0059] like Figure 1 and Figure 6 As shown, multiple columns 15 are fixedly installed on the positioning base 13. Linear electric cylinders I 17 are rotatably installed on two columns 15 near the guide arm 14. The movable end of the linear electric cylinder I 17 is rotatably connected to the support column 22.

[0060] Two linear electric cylinders I17 are activated simultaneously, driving two docking actuators 21 to move towards or away from each other on both sides of the guide arm 14. An opening matching the diameter of the sapling trunk is reserved, allowing multiple digging modules 3 to act stably on the periphery of the sapling. Through multiple reciprocating digging at multiple points, the integrity of the root system structure is ensured during the digging process, avoiding root pulling damage when the tree is separated from the original planting area, and enabling the tree roots to be separated from the original substrate without damage.

[0061] In this embodiment, the bottom two sides of the shovel body 31 are integrally formed with cutting blades; when facing hawthorn trees and similar seedlings with small root systems, the tree roots are pruned manually; when facing seedlings with large root systems, such as apple trees and banyan trees, the cutting blades are used to prune the tree roots by controlling the rotation of the docking execution arm 21 on the guide rail arm 14, and the roots are cut before the flower bud differentiation period to change endogenous hormones to promote reproductive growth and achieve the purpose of increasing production.

[0062] Example 3:

[0063] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the L-shaped seat 11 is connected to the positioning base 13 via a travel limiting stake 12. The travel limiting stake 12 and the L-shaped seat 11 are detachably and fixedly connected, and the travel limiting stake 12 and the positioning base 13 are slidably connected by insertion. The positioning base 13 is provided with a circular hole 131. The travel limiting stake 12 passes through the circular hole 131 from top to bottom and extends downward toward the lower side of the circular hole 131. The diameter of the circular hole 131 is larger than the diameter of the travel limiting stake 12. A limiting plate is provided at the bottom of the travel limiting stake 12. The upper side of the limiting plate abuts against the lower side of the positioning base 13. The diameter of the limiting plate is larger than the diameter of the circular hole 131. Multiple columns 15 are fixedly installed on the positioning base 13, and tension springs 16 are respectively installed between the travel limiting stake 12 and the multiple columns 15.

[0064] The travel limit stake 12 is locked on the positioning base 13 and can only move horizontally with a small amplitude but cannot move vertically. Under the action of multiple tension springs 16, the travel limit stake 12 always tends to move towards the center of the circular hole 131 on the positioning base 13. When using multiple shovel modules 3 to clamp the trunk of the tree, the flexible anti-damage clamps 34 on the top of the multiple shovels 31 abut against the outer side of the tree branches. Since the travel limit stake 12 can move horizontally with a small amplitude, a displacement compensation mechanism is formed, which can realize the automatic adjustment of the relative position of the docking execution arm 21 and the tree, ensuring that the movement trajectory of the multiple shovels 31 is adapted to the root gathering area of ​​the tree, avoiding the excessive volume of the excavated tree root soil ball, which would cause the roots to curl and entangle during subsequent planting. It is highly convenient to prune the root area of ​​the seedling and the operation difficulty of the excavation arm is low.

[0065] To facilitate the disassembly, replacement, and maintenance of tension spring 16, such as Figure 5 As shown, quick-release sleeves I 161 and II 162 are fixedly installed at both ends of the tension spring 16, and quick-release sleeves I 161 and II 162 are detachably and fixedly installed on the column 15 and the travel limit stake 12, respectively.

[0066] Example 4:

[0067] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, in this embodiment, the upper side of the docking execution arm 21 is connected to the drive seat 23 via the support column 22. A linear electric cylinder II 25 is rotatably mounted on the bottom of the drive seat 23. A U-shaped drive control seat 26 is fixedly mounted on the movable end of the linear electric cylinder II 25. The U-shaped drive control seat 26 is rotatably connected to the horizontal pins 33 on both sides of the shovel body 31.

[0068] The linear electric cylinder II 25 is activated, driving the shovel body 31 to rotate inside the stroke limit post 12. During this process, the arc-shaped slider 24 slides in the arc-shaped groove 32, the linear electric cylinder II 25 rotates relative to the drive seat 23, and the U-shaped drive control seat 26 rotates relative to the horizontal pin 33. Since the horizontal pin 33 is close to the middle of the shovel body 31, the U-shaped drive control seat 26 is prevented from protruding into the inner area of ​​the shovel body 31 in the horizontal direction, so as not to affect the stable contact between the flexible anti-damage clamp 34 and the outer side of the tree branches.

[0069] Compared to the first embodiment, the above-mentioned solution in this embodiment can effectively address the problem of limited installation space for the drive components inside the docking arm 21. By adjusting the installation position of the linear electric cylinder II 25 on the lower side of the drive seat 23 and optimizing the force application angle of the U-shaped drive control seat 26 on the cross pin 33, the rotational stability and action continuity of the shovel body 31 can be ensured.

[0070] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.

[0071] Apart from the technical features described in the specification, the other technical features are known to those skilled in the art. To highlight the innovative features of this invention, the other technical features will not be described in detail here.
