Description

Technical Field

[0001] This utility model relates to the field of tree transplanting equipment technology, and more specifically to a vehicle-mounted rear-mounted tree digger tree transplanting equipment. Background Technology

[0002] In the process of planting and cultivating trees in gardens, the saplings are first planted densely on the ground at equal intervals. When the age, diameter or height of the saplings reaches the standards for transplanting or sale, they are dug up along with the soil around their roots. The soil is then wrapped with straw ropes or other similar items to retain moisture and stabilize the soil before being transported to the transplanting destination. At the transplanting destination, transplanting pits are dug and the trees are transplanted. Currently, tree diggers are used to directly excavate trees that have reached the standards for transplanting or sale. However, due to differences in soil moisture content, the soil hardness varies. When the moisture content is low, the soil becomes harder, making it difficult for tree diggers to dig. They need to insert the blades one by one, repeating the process until the soil is fully inserted. Moreover, because the weight of the tree digger is insufficient to hold down the blades, the blades may even tilt upwards due to the reaction force, causing the digging to deviate or fail. In addition, the tree digger's tree-moving assembly has a limited deflection angle, making it impossible to dig trees growing on slopes. Utility Model Content

The wear-resistant strip 75 is slidably installed inside the guide frame 74; the top of the guide frame is provided with a lower blade cylinder hinge seat, and a lower blade cylinder 71 is hinged on the guide frame hinge seat. The piston rod ear plate of the lower blade cylinder 71 is connected to the lower blade hinge seat 76;The tree-moving assembly 7 is connected to the forearm 5 via the tree-moving assembly hinge seat 72 and the second forearm bushing 55. The hinge seat of the angle-adjusting cylinder 6 is hinged to the piston rod lug of the angle-adjusting cylinder 6.

[0016] The first embodiment of this utility model is as follows: A base 8 is fixed in the middle of the vehicle body 1. The main arm 3 is hinged to the rear of the base 8, and a main arm cylinder 2 is hinged to the front. The other end of the main arm cylinder 2 is connected to the middle of the main arm 3. An L-shaped forearm 5 is hinged to the upper end of the main arm 3, and a forearm cylinder 4 is hinged to the middle. The other end of the forearm cylinder 4 is connected to the middle of the forearm 5. A tree-moving assembly 7 is hinged to the end of the forearm 5, and an angle-adjusting cylinder 6 is hinged to the end near the main arm 3. The other end of the angle-adjusting cylinder 6 is connected to the tree-moving assembly hinge seat 72.

[0017] The vehicle body 1 refers to the mobile platform that carries the equipment, providing a foundation for operational movement. The base 8 is a support structure fixed to the middle of the vehicle body 1, which can be installed via bolts and is used to distribute the reaction force during the operation of the robotic arm. The boom 3 is the primary robotic arm connecting the base 8 and the tree-moving assembly 7, connected to the base 8 via a hinge, and its pitch angle is adjusted by a hydraulic cylinder. The boom cylinder 2 is a hydraulic actuator that drives the boom 3 to rotate; its cylinder body is hinged to the base 8, and its piston rod clasp is hinged to the boom 3, controlling the boom 3's angle through extension and retraction. The forearm 5 is the secondary robotic arm connecting the boom 3 and the tree-moving assembly 7, using an L-shaped structure to extend the end-effector's working range, and its angle relative to the boom 3 is changed by a hydraulic cylinder. The angle-adjusting cylinder 6 is a hydraulic actuator that adjusts the tilt angle of the tree-moving assembly 7; one end is hinged to the forearm 5, and the other end is connected to the tree-moving assembly hinge seat 72.

[0018] Specifically, the base 8 is bolted to the middle of the vehicle body 1, and the upper arm 3 is hinged to the rear of the base 8 to form a fulcrum. When the upper arm cylinder 2 extends or retracts, it pushes the upper arm 3 to rotate around the hinge point, changing the overall height of the robotic arm. The lower arm 5 is connected to the upper end of the upper arm 3 through the hinge point, and the lower arm cylinder 4 drives the lower arm 5 to adjust the working radius. The tree-moving assembly 7 is hinged to the end of the L-shaped lower arm 5, and the angle adjustment cylinder 6 changes the tilt angle of the tree-moving assembly 7 by extending or retracting. When excavating hard soil, the weight of the vehicle body 1 is transmitted to the robotic arm through the base 8, increasing the downward pressure of the lower blade 77. When working on a slope, the angle adjustment cylinder 6 adjusts the angle between the tree-moving assembly 7 and the ground to ensure that the lower blade 77 cuts at an accurate angle.

[0019] Through the above technical solution, this application can stably press down the lower blade 77 when operating in hard soil, preventing the component from tilting due to reaction force. The multi-stage articulated structure, combined with the hydraulic cylinder drive, enables multi-angle adjustment of the tree-moving assembly 7 to adapt to the excavation needs under different terrain conditions. The rigid connection design between the base 8 and the vehicle body 1 enhances structural stability and improves the success rate of excavation operations.

[0020] This application further proposes that the base 8 includes a base plate 82, which is connected to the vehicle body 1 by bolts; a base hinge seat 81 is provided at the front end of the base 8, and a base hinge ear plate 83 is provided on the base hinge seat 81; a base cylinder hinge seat 85 is provided at the rear end of the base 8, and the piston rod clevis of the boom cylinder 2 is hinged to the base cylinder hinge seat 85; a plurality of base upright plates 84 are also provided on the base 8, and the base upright plates 84 are fixedly connected to the base hinge seat 81 and the base cylinder hinge seat 85.

[0021] The base plate 82 is a flat plate component that supports the overall structure of the base 8. It can be made by cutting and forming a steel plate and creating bolt holes, used to detachably connect the base 8 to the vehicle body 1. The base hinge seat 81 is a support component located at the front end of the base 8 for installing the hinge structure. It can be fixedly connected to the base 8 using welding or casting processes. The base hinge ear plate 83 inside it cooperates with the boom bushing 31 to form a rotating pair, and a wear-resistant sleeve is provided to improve durability. The base upright plate 84 is a reinforcing plate perpendicular to the base plate 82. It can be made by welding multiple steel plates at intervals between the base hinge seat 81 and the base cylinder hinge seat 85, used to improve the overall rigidity of the base 8 and distribute stress.

[0022] Specifically, the base plate 82 is bolted to the vehicle body 1, allowing the base 8 to be disassembled for maintenance and its installation position to be adjustable. The base hinge seat 81 cooperates with the boom bushing 31 to form a rotation fulcrum, and the base cylinder hinge seat 85 is hinged with the boom cylinder piston rod lug to form a drive fulcrum. Together, they constitute the swing drive structure of the boom 3. The base upright plate 84 connects the base hinge seat 81, the cylinder hinge seat, and the base plate 82 into one unit by welding, effectively suppressing the deformation of the base 8 when the cylinder applies force. When the boom cylinder 2 extends or retracts, the driving force is transmitted to the base upright plate 84 through the cylinder hinge seat, and then distributed from the base upright plate 84 to the entire base plate 82, avoiding local stress concentration that could lead to structural failure.

[0023] Through the above technical solution, this application solves the problem of the lower blade 77 tilting during operation due to insufficient structural strength of the base 8 of a traditional tree digger. The combined design of the base upright plate 84 and the hinge seat enhances the overall rigidity of the base 8, enabling the driving force of the boom cylinder 2 to be stably transmitted to the lower blade 77, avoiding the tilting of the lower blade 77 caused by deformation of the base 8. The bolted connection structure reduces the maintenance difficulty of the base 8 and allows for quick adjustment of the installation position to adapt to different operational needs under complex working conditions.

[0024] This application further proposes a vehicle-mounted rear-mounted tree digger and tree transplanting device. The boom 3 has an I-shaped structure, including two boom side plates 32 and a boom upright plate 33 located between the two boom side plates 32. One end of the boom side plate 32 is provided with a boom bushing 31, and the other end of the boom side plate 32 is provided with a boom hinge seat 35. The boom upright plate 33 is provided with a boom cylinder hinge seat 34. The boom 3 is connected to the base 8 through the coupling of the boom bushing 31 and the base hinge ear plate 83. The boom 3 is hinged to the boom cylinder 2 through the boom cylinder hinge seat 34 and the adjustable nut of the boom cylinder 2.

[0025] The I-beam structure refers to a frame with an I-shaped cross-section formed by two parallel boom side plates 32 and a vertical boom upright plate 33. The plates can be assembled using welding or bolting. This structure maintains lightweight design while enhancing bending strength. Specifically, the I-beam boom 3 structure forms a three-dimensional support frame through the combination of side plates and upright plates, which can evenly distribute the reaction force from the soil during excavation operations. The coupling between the boom bushing 31 and the base hinge lug 83 forms a rotating pair, allowing the boom 3 to pitch around the base 8. The connection between the boom cylinder hinge seat 34 and the boom cylinder 2 ensures that the cylinder's push-pull force acts directly on the central axis of the boom upright plate 33, avoiding deformation caused by lateral loads. Under hard soil conditions, this structure effectively suppresses equipment vibration caused by reaction forces during operation by enhancing the overall rigidity of the boom 3 and optimizing the force path.

[0026] Through the above technical solution, this application solves the problem of the lower blade 77 tilting up due to the force exerted on the boom 3 when the soil is hard. The I-beam structure allows the boom 3 to maintain a stable posture under complex working conditions, and the centrally located layout of the boom cylinder hinge seat 34 ensures effective transmission of driving force, thereby improving the linearity of the lower blade 77 during the pressing process. The rotatable connection between the boom bushing 31 and the base 8 enhances the equipment's adaptability to sloping terrain, allowing the tree transplanting assembly 7 to be adjusted to the optimal digging angle.

[0027] This application further proposes that the forearm 5 includes two forearm side plates 53 and a first connecting beam 52 and a second connecting beam 54 located between the two forearm side plates 53 and perpendicular to the forearm side plates 53; a first forearm bushing 51 is provided at one end of the forearm side plate 53, and a second forearm bushing 55 is provided at the other end of the forearm side plate 53; a forearm angle adjustment cylinder hinge seat is provided in the middle of the first connecting rod 52, and a groove is provided below the middle of the second connecting rod 54; the forearm 5 is connected to the upper arm 3 through the coupling of the first forearm bushing 51 and the upper arm hinge seat 35, and the forearm angle adjustment cylinder hinge seat is hinged to the cylinder mounting seat of the angle adjustment cylinder 6.

[0028] The forearm side plate 53 refers to the plate-shaped component constituting the main structure of the forearm 5. It can be made by cutting and forming a steel plate with a thickness of 8-12mm, and has bushings at both ends for connecting other components. The first connecting beam 52 and the second connecting beam 54 are supporting components that laterally connect the two forearm side plates 53. They can be made by welding and fixing square tubes or other cross-sectional shapes of steel pipes to enhance the torsional resistance of the forearm 5 structure. The first forearm bushing 51 is a hollow cylindrical component located at one end of the forearm side plate 53, used to cooperate with the boom hinge seat 35 to form a rotating pair. The forearm angle adjustment cylinder hinge seat is a connecting structure fixed in the middle of the first connecting rod 52, used to install the cylinder mounting seat of the angle adjustment cylinder 6. The groove is a notch structure located below the middle of the second connecting beam 54, used to avoid the movement trajectory of the angle adjustment cylinder 6, effectively increasing the angle coverage range of the tree-moving assembly 7.

[0029] Specifically, two forearm side plates 53 are arranged in parallel to form the main frame, and the first connecting rod 52 and the second connecting rod 54 are welded laterally between the side plates to form a stable support structure. The first forearm bushing 51 is installed at the front end of the forearm side plate 53 and is connected to the upper arm hinge seat 35 by a pin to achieve rotational freedom. The second forearm bushing 55 is located at the end of the forearm side plate 53 and is used to connect the tree-moving assembly 7. The cylinder mounting seat of the angle-adjusting cylinder 6 is fixed to the forearm angle-adjusting cylinder hinge seat by a pin, and the piston rod clevis is connected to the tree-moving assembly 7, driving the angle adjustment of the tree-moving assembly 7 through the extension and retraction of the cylinder. The groove in the middle of the second connecting rod 54 provides movement space when the tree-moving assembly 7 deflects, effectively raising the angle coverage range of the tree-moving assembly 7.

[0030] Through the above technical solution, this application effectively solves the problem of deflection caused by insufficient structural strength of the forearm 5 when the lower blade shovel 77 is inserted into hard soil. The reinforced forearm 5 frame structure ensures that the force is stably transmitted to the lower blade shovel 77. The groove design, together with the angle-adjusting cylinder 6, expands the deflection angle range of the tree-moving assembly 7 to meet the excavation needs of different slope terrains.

[0031] This application further proposes a tree-transfer assembly 7 including a fixed frame 73, an ear plate on the fixed frame 73, an angle-adjusting cylinder 6 hinge seat on the upper end of the ear plate, a tree-transfer assembly hinge seat 72 in the middle of the fixed frame 73, and several guide frames evenly arranged on the fixed frame 73, with slide rails 74 on the guide frames; the tree-transfer assembly 7 also includes a lower blade shovel 77, with a lower blade shovel hinge seat 76 and a wear-resistant strip 75 on the upper part of the lower blade shovel 77, the wear-resistant strip 75 moving up and down along the slide rail in a slidable manner; a lower blade cylinder hinge seat is provided at the top of the guide frame, and a lower blade cylinder 71 is hinged on the guide frame hinge seat, the piston rod shackle of the lower blade cylinder 71 is connected to the lower blade shovel hinge seat 76; the tree-transfer assembly 7 is connected to the forearm 5 through the coupling of the tree-transfer assembly hinge seat 72 and the second forearm bushing 55, and the angle-adjusting cylinder 6 hinge seat is hinged to the piston rod shackle of the angle-adjusting cylinder 6.

[0032] The fixed frame 73 refers to a ring-shaped support structure used to fix the guide frame and provide a sliding track for the lower blade 77. The sliding strip 74 is a plate-shaped component with guide grooves, used to constrain the movement trajectory of the wear-resistant strip 75, ensuring the lower blade 77 maintains the correct orientation when inserted into the soil. The sliding strip 74 has an arc-shaped structure, allowing the lower blade 77 to insert into the soil along an arc trajectory, directly forming a soil ball and excavating tree roots directly. The wear-resistant strip 75 is a sliding component that cooperates with the sliding strip 74, specifically a nylon or metal slider, which reduces the frictional resistance between the lower blade 77 and the guide frame through sliding. The lower blade cylinder 71 is a hydraulic actuator, specifically a single-acting cylinder, which applies downward pressure to the lower blade 77 through the extension and retraction of the piston rod, causing the lower blade 77 to insert into the soil.

[0033] Through the above technical solution, this application solves the problems of difficulty in inserting the cutting blade 77 into hard soil and easy lifting. At the same time, the angle adjustment mechanism expands the working range of the tree transplanting assembly 7, enabling it to stably complete the excavation operation in sloping terrain, thereby improving excavation efficiency and success rate.

[0034] Specifically, the lower blade 77 slides along the guide frame through the cooperation of the wear-resistant strip 75 and the slide rail 74. When the lower blade 77 is inserted into the soil, the piston rod of the lower blade cylinder 71 retracts, which can drive the lower blade 77 to move downward. The wear-resistant strip 75 slides in the slide rail 74 to prevent the lower blade 77 from deviating.

[0035] The fixing frame 73 is an openable structure, mainly composed of three arc-shaped structures that can form a ring structure. The three arc-shaped structures include a semi-circular structure with a 180-degree opening angle and two arc-shaped structures with a 90-degree opening angle. They are connected by a pin hinge. When in use, they can be unfolded to form an opening for the tree trunk to enter, and then merged into a complete circular structure. The specific structure of this device is existing technology and will not be described in detail here.

[0036] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
