Description

Technical Field

[0001] This invention relates to the field of tree transplanting technology, specifically to a forestry tree planting and seedling transplanting device. Background Technology

[0002] In existing forestry tree planting and transplanting devices, the placement mechanism for placing trees with soil balls into planting holes generally adopts a vertical descent method. This type of placement mechanism typically uses a drive assembly to move the clamping components or sleeves vertically downwards, placing the tree directly into the pre-dug planting hole in a vertical position.

[0003] However, because the walls and bottom of the planting pit are not perfectly regular, and the shape of the root ball is also irregular, hard collisions and compressions easily occur between the bottom of the root ball and the bottom of the pit, and between the side of the root ball and the pit wall, during vertical descent. This instantaneous impact force is directly transmitted to the root system inside the root ball, causing a large number of capillary roots to break and the taproot to be damaged, severely reducing the survival rate of trees after transplanting. Especially when the root ball has a high water content and a large weight, the impact inertia during vertical descent is more significant, and the root damage problem is more prominent. In view of this, we propose a forestry tree planting and seedling transplanting device. Summary of the Invention

[0004] The purpose of this invention is to provide a forestry tree planting, seedling cultivation and transplanting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forestry tree planting and seedling transplanting device, comprising a connecting frame, a sliding arm slidably installed on the inner wall of the connecting frame, a hydraulic cylinder fixedly installed on the top of the connecting frame, the movable end of the hydraulic cylinder being fixedly connected to the upper surface of the sliding arm, an arc-shaped sleeve hinged to the side wall of the sliding arm via a hydraulic telescopic arm, a right cover being movably connected to the side wall of the arc-shaped sleeve, a hydraulic gripper being provided inside the right cover, and a rotating module for safe transplanting of seedling roots being provided on one side of the right cover; The rotating module includes a left cover hinged to the right cover. Both the left and right covers have connecting rings fixedly installed on their outer surfaces that slide with the arc-shaped sleeve. The outer surfaces of the left and right covers are provided with spiral grooves. The side wall of the connecting frame is fixedly installed with a fixing plate. The side wall of the fixing plate is fixedly installed with a convex ball that moves with the spiral groove.

[0006] Preferably, both the left and right covers are semi-cylindrical, and when combined, they form a complete cylinder. The left and right covers are exactly the same size, and the inner cavity of the cylinder provides a uniform circumferential space for the sapling root ball, ensuring that the root ball is evenly constrained and protected inside the cylinder.

[0007] Preferably, the connecting ring is T-shaped, and the inner surface of the arc sleeve is provided with a connecting groove that matches the shape of the connecting ring. The T-shaped cross-sectional structure allows the connecting ring to slide freely in the circumferential direction within the connecting groove, while it is restricted and positioned radially and axially by the sidewalls of the connecting groove. This ensures that the left and right covers can be stably suspended on the arc sleeve after they are closed, thus guaranteeing rotational freedom and preventing the covers from falling off the arc sleeve.

[0008] Preferably, the spiral grooves on the outer surfaces of the left and right covers cooperate to form a complete spiral shape, and the diameter of the spiral is the same as the outer diameter of the connecting body of the left and right covers, so that the spiral groove is located on the outermost side of the connecting body, ensuring that the convex ball on the fixing plate can form an effective contact with the spiral groove without interference.

[0009] Preferably, the surface of the fixing plate near the left and right covers is formed into an arc shape, and the arc-shaped surface is in contact with the outer surfaces of the left and right covers. The arc-shaped end of the fixing plate maintains a uniform and small gap between its end face and the outer surface of the rotating cover, so as to avoid the convex ball being unable to be effectively embedded in the spiral groove due to excessive gap.

[0010] Preferably, the bottom of the left and right covers is provided with a bottom protection component to protect the root ball of the transplanted trees. The bottom protection component includes a flexible arc-shaped cover disposed at the bottom of the left and right covers. The top outer surface of the flexible arc-shaped cover is provided with an annular groove, and the bottom outer arc surface of the flexible arc-shaped cover is provided with multiple sets of grooves arranged in a circumferential array.

[0011] Preferably, the depth of the groove gradually decreases from bottom to top, and the edges of the groove are all set in a right angle shape, so that the groove forms a large volume of soil scraping cavity at the bottom of the flexible arc-shaped cover. As the flexible arc-shaped cover rotates, the soil at the bottom of the planting hole is fully scraped into the groove and carried upward with the cover.

[0012] Preferably, the top of the bottom protection assembly is provided with a torsion assembly that shifts position with rotation. The torsion assembly includes a sliding groove formed at the bottom of the left and right covers. An arc rod is fixedly installed on the inner wall of the sliding groove. A T-shaped ring is slidably installed through the outer wall of the arc rod. The bottom end of the T-shaped ring is fixedly connected to the top surface of the flexible arc cover. A spring is fixedly connected between the end of the T-shaped ring and the inner wall of the end of the sliding groove.

[0013] Preferably, the included angle between the two ends of the sliding groove is smaller than the included angle between the two ends of the left cover, and the two end faces of the flexible arc-shaped cover are flush with the two end faces of the left cover, ensuring that the bottom protection component forms a complete and uniform wrapping protection for the soil ball when closed.

[0014] Compared with the prior art, the present invention provides a forestry tree planting and seedling transplanting device, which has the following beneficial effects: 1. This forestry tree planting and transplanting device, by setting up a left and right cover shell with spiral grooves on their outer surfaces, and cooperating with convex balls fixed on the connecting frame, allows the left and right cover shells to be driven vertically by hydraulic cylinders to descend. The convex balls are embedded in the spiral grooves to form a motion guiding cooperation, forcing the left and right cover shells to rotate around their own axes while descending. This spiral descent places the seedling into the planting hole, and the soil ball gradually enters the planting hole in a rotating and screwing manner. The bottom of the soil ball and the bottom of the hole, as well as the side of the soil ball and the wall of the hole, make progressive contact. This avoids the instantaneous impact force caused by hard collision and compression between the soil ball and the planting hole in the traditional vertical descent method, and solves the problem of instantaneous impact force being transmitted to the inside of the soil ball in the vertical descent method, causing capillary root breakage and taproot damage.

[0015] 2. This forestry tree planting and transplanting device features flexible arc-shaped covers at the bottom of the left and right covers. These covers undergo adaptive elastic deformation as they spiral down to contact the bottom of the planting hole. Their arc-shaped inner surfaces provide wrapping support for the bottom of the root ball, preventing the soil from scattering due to vibration during descent. Simultaneously, an annular groove on the top outer surface of the flexible arc-shaped cover provides a predetermined deformation area. When the bottom of the cover is compressed, the material at the annular groove preferentially bends and deforms, guiding the cover to contract inward in the expected direction to conform to the contour of the root ball. This further enhances the wrapping and support effect of the flexible arc-shaped cover on the root ball, solving the problem of soil scattering due to vibration and impact during placement in traditional transplanting devices, leading to exposed roots.

[0016] 3. This forestry tree planting and transplanting device, by setting a torsion component at the top of the bottom protection component, when the flexible arc-shaped cover encounters uneven resistance between the soil ball and the hole wall during the spiral descent, the flexible arc-shaped cover drives the T-shaped ring to slide along the arc rod in the sliding groove. The spring absorbs the deflection impact of the flexible arc-shaped cover through its elastic deformation, avoiding excessive deformation or damage to the flexible arc-shaped cover due to excessive local force. After the resistance is eliminated, the spring drives the T-shaped ring to reset, so that the flexible arc-shaped cover returns to the center position with the left and right cover shells, thereby ensuring that the flexible arc-shaped cover can still form a uniform wrapping and support for the soil ball in subsequent operations. This solves the problem that the flexible arc-shaped cover deflects and misaligns due to uneven resistance between the soil ball and the hole wall during the spiral descent, and cannot effectively support the bottom of the soil ball.

[0019] like Figures 1-6 As shown, the present invention provides a technical solution: a forestry tree planting and seedling transplanting device, including a connecting frame 1, a sliding arm 2 slidably installed on the inner wall of the connecting frame 1, a hydraulic cylinder 3 fixedly installed on the top of the connecting frame 1, the movable end of the hydraulic cylinder 3 being fixedly connected to the upper surface of the sliding arm 2, an arc sleeve 5 hinged to the side wall of the sliding arm 2 through a hydraulic telescopic arm 4, a right cover 6 movably connected to the side wall of the arc sleeve 5, a hydraulic gripper 7 being provided inside the right cover 6, and a rotating module 8 for safe transplanting of seedling roots being provided on one side of the right cover 6; The rotating module 8 includes a left cover 81 hinged to one side of the right cover 6. Both the outer surfaces of the left cover 81 and the right cover 6 are fixedly equipped with connecting rings 82 that slide with the arc sleeve 5. The outer surfaces of the left cover 81 and the right cover 6 are provided with spiral grooves 83. The side wall of the connecting frame 1 is fixedly equipped with a fixing plate 84. The side wall of the fixing plate 84 is fixedly equipped with a convex ball 85 that moves with the spiral groove 83.

[0020] The connecting frame 1 serves as the installation base for the entire device. The sliding arm 2 is slidably mounted on its inner wall to provide vertical lifting and lowering motion guidance for the subsequent actuators. The movable end of the hydraulic cylinder 3 is fixedly connected to the upper surface of the sliding arm 2. When the hydraulic cylinder 3 extends or retracts, it drives the sliding arm 2 to slide up and down along the inner wall of the connecting frame 1, thereby realizing the vertical position adjustment of the entire working component. The side wall of the sliding arm 2 is hinged to the arc sleeve 5 through the hydraulic telescopic arm 4. The extension and retraction of the hydraulic telescopic arm 4 can push the arc sleeve 5 and its connected components forward or backward in the horizontal direction to achieve precise alignment of the planting hole position. The side wall of the arc sleeve 5 is movably connected to the right cover 6. The hydraulic clamp 7 set inside the right cover 6 is used to clamp and fix the seedling soil ball during the transplanting process to prevent the soil ball from shaking or falling off during movement and placement.

[0021] In the rotating module 8, the left cover 81 is hinged to one side of the right cover 6. The two can open and close relative to each other to facilitate the insertion of seedlings from the side. When closed, they form a complete cylindrical wrapping structure. The connecting rings 82 fixedly installed on the outer surfaces of the left cover 81 and the right cover 6 form a sliding fit with the arc sleeve 5, allowing the left cover 81 and the right cover 6 to rotate freely under the support of the arc sleeve 5 after they are closed. The spiral grooves 83 opened on the outer surfaces of the left cover 81 and the right cover 6 form a motion fit with the convex ball 85 installed on the side wall fixing plate 84 of the connecting frame 1. When the hydraulic cylinder 3 drives the sliding arm 2 to drive the entire working part to descend vertically, the convex ball 85 is embedded in the spiral groove 83. The guiding effect of the spiral groove 83 forces the left cover 81 and the right cover 6 to generate a rotational motion around their own axis while descending, thereby placing the seedling into the planting hole in a spiral descent manner, avoiding damage to the root system inside the soil ball caused by the hard impact of vertical descent.

[0022] Both the left cover 81 and the right cover 6 are set in a semi-cylindrical shape. When the two are combined, they form a complete cylinder, and the left cover 81 and the right cover 6 are exactly the same size.

[0023] The inner cavity of the cylindrical body provides a uniform circumferential space for the sapling's root ball, ensuring that the root ball is evenly constrained and protected inside the cylinder. The complete cylindrical structure after being closed has good dynamic balance characteristics when rotating around its own axis, avoiding vibration and eccentric swaying caused by uneven mass distribution, thus ensuring the smoothness of the spiral descent process. At the same time, the identical left and right halves design makes the processing technology of the left cover 81 and the right cover 6 consistent, reducing manufacturing costs. Moreover, the symmetry of the movement of the left and right sides during the opening and closing action is better, which facilitates the synchronous drive control of hydraulic or pneumatic components.

[0024] The connecting ring 82 is T-shaped, and the inner surface of the arc sleeve 5 is provided with a connecting groove that matches the shape of the connecting ring 82.

[0025] The T-shaped cross-section structure allows the connecting ring 82 to slide freely in the circumferential direction within the connecting groove, while it is restricted and positioned radially and axially by the sidewalls of the connecting groove. This ensures that the left cover 81 and the right cover 6 can be stably suspended on the arc sleeve 5 after they are closed, guaranteeing both rotational freedom and preventing the cover from falling off the arc sleeve 5. The T-shaped mating structure also serves to transmit vertical loads. When the left cover 81 and the right cover 6 encounter soil resistance during the spiral descent, this resistance is transmitted to the arc sleeve 5 through the connecting ring 82, and then to the connecting frame 1 via the hydraulic telescopic arm 4 and the sliding arm 2, forming a complete force path and ensuring structural strength.

[0026] The spiral grooves 83 on the outer surfaces of the left cover 81 and the right cover 6 cooperate to form a complete spiral shape, and the diameter of the spiral is the same as the outer diameter of the combined body of the left cover 81 and the right cover 6.

[0027] This ensures that the spiral groove 83 is located on the outermost side of the outer surface of the connecting body, allowing the convex ball 85 on the fixing plate 84 to form an effective contact with the spiral groove 83 without interference. The complete spiral structure ensures that when the left cover 81 and the right cover 6 are closed, the convex ball 85 can smoothly slide into the spiral groove 83 from the starting end and move continuously along the entire spiral groove 83. There is no problem of jamming or interruption of movement caused by misalignment of the spiral groove 83, thus ensuring that the spiral descent action remains continuous, uniform, and stable throughout the entire descent stroke.

[0028] The surface of the fixing plate 84 near the left cover 81 and the right cover 6 is set in an arc shape, and the arc-shaped surface is in contact with the outer surface of the left cover 81 and the right cover 6.

[0029] The arc-shaped end of the fixed plate 84 maintains a uniform and small gap between its end face and the outer surface of the rotating cover. This prevents the convex ball 85 from failing to effectively embed into the spiral groove 83 due to an excessively large gap, and also prevents frictional interference between the cover and the fixed plate 84 during rotation due to an excessively small gap. The fitting arc surface also provides auxiliary guidance for the rotation of the left cover 81 and the right cover 6. When the cover experiences a slight radial sway during the spiral descent, the arc surface can act as a limiting constraint to ensure the stability of the rotation axis.

[0030] The bottom of the left cover 81 and the right cover 6 are provided with bottom protection components 9 to protect the root ball of transplanted trees. The bottom protection components 9 include flexible arc-shaped covers 91 set at the bottom of the left cover 81 and the right cover 6. The top outer surface of the flexible arc-shaped cover 91 is provided with an annular groove 93, and the bottom outer arc surface of the flexible arc-shaped cover 91 is provided with multiple sets of grooves 92 arranged in a circular array.

[0031] The flexible arc-shaped cover 91 is made of a flexible material with elasticity. During the spiral descent of the cover to contact the bottom of the planting hole, the flexible arc-shaped cover 91 can undergo adaptive elastic deformation to absorb the impact energy between the soil ball and the bottom of the hole. At the same time, its arc-shaped inner surface forms a wrapping support for the bottom of the soil ball, preventing the soil at the bottom of the soil ball from scattering due to vibration during descent. The annular groove 93 opened on the outer surface of the top of the flexible arc-shaped cover 91 provides a predetermined deformation area for the flexible arc-shaped cover 91. When the bottom of the flexible arc-shaped cover 91 is squeezed, the material at the annular groove 93 preferentially bends and deforms, thereby guiding the flexible arc-shaped cover 91 to shrink inward in the expected direction to fit the contour of the bottom of the soil ball. Multiple sets of grooves 92 arranged in a circumferential array on the outer arc surface of the bottom of the flexible arc-shaped cover 91 are used to scrape and contain loose soil at the bottom and side walls of the planting hole during the spiral descent, so that the soil is brought into the annular gap between the soil ball and the hole wall as the flexible arc-shaped cover 91 rotates, playing an auxiliary role in covering the soil.

[0032] The depth of the groove 92 gradually decreases from bottom to top, and the edges of the groove 92 are all set in a right angle shape.

[0033] The groove 92 has the greatest depth at the bottom edge of the flexible arc-shaped cover 91, and the depth decreases as it approaches the top. This creates a large-volume scraping cavity at the bottom of the flexible arc-shaped cover 91. As the flexible arc-shaped cover 91 rotates, the soil at the bottom of the planting hole is fully scraped into the groove 92 and carried upward with the cover. As the depth of the groove 92 gradually decreases, the soil is gradually squeezed out of the groove 92 and falls into the gaps around the root ball, achieving uniform soil coverage. The edges of the groove 92 are all set in a right angle shape. Right angle edges have a stronger scraping ability than rounded edges, and can more effectively cut into the soil when the flexible arc-shaped cover 91 rotates, breaking up and scraping up the compacted or compacted soil, ensuring scraping efficiency and soil coverage effect.

[0034] The top of the bottom protection component 9 is provided with a torsion component 10 that shifts position with rotation. The torsion component 10 includes a sliding groove 101 opened at the bottom of the left cover 81 and the right cover 6. An arc rod 102 is fixedly installed on the inner wall of the sliding groove 101. A T-shaped ring 103 is slidably installed through the outer wall of the arc rod 102. The bottom end of the T-shaped ring 103 is fixedly connected to the top surface of the flexible arc cover 91. A spring 104 is fixedly connected between the end of the T-shaped ring 103 and the inner wall of the end of the sliding groove 101.

[0035] The sliding grooves 101 at the bottom of the left cover 81 and the right cover 6 provide a circumferential sliding track space for the T-ring 103. The arc rod 102 is fixedly installed on the inner wall of the sliding groove 101 and passes through the T-ring 103. The T-ring 103 can slide back and forth in the sliding groove 101 along the axial direction of the arc rod 102. The bottom end of the T-ring 103 is fixedly connected to the top surface of the flexible arc cover 91, so that the flexible arc cover 91 moves together with the T-ring 103. The spring 104 is connected to the T-ring 103. When the flexible arc-shaped cover 91 encounters uneven resistance between the soil ball and the cavity wall during its spiral descent, it drives the T-shaped ring 103 to slide along the arc rod 102 within the sliding groove 101. The spring 104 is compressed or stretched, and the deflection impact is absorbed through the elastic deformation of the spring 104. After the resistance is eliminated, the spring 104 drives the T-shaped ring 103 to reset, so that the flexible arc-shaped cover 91 returns to its centering position with the left cover 81 and the right cover 6.

[0036] The included angle between the two ends of the sliding groove 101 is smaller than the included angle between the two ends of the left cover 81, and the two end faces of the flexible arc cover 91 are flush with the two end faces of the left cover 81.

[0037] The circumferential extension range of the sliding groove 101 is limited within the respective angular ranges of the left cover 81 and the right cover 6, ensuring that the sliding stroke of the T-shaped ring 103 within the sliding groove 101 does not exceed the physical boundary of the left cover 81 or the right cover 6, thus preventing the T-shaped ring 103 from sliding out of the sliding groove 101 and causing the flexible arc-shaped cover 91 to fall off. The two end faces of the flexible arc-shaped cover 91 are flush with the two end faces of the left cover 81, so that when the left cover 81 and the right cover 6 are closed, the end faces of the flexible arc-shaped covers 91 on both sides can be aligned and fitted together to form a complete annular cover, without gaps or overlaps caused by uneven end faces, ensuring that the bottom protection component 9 provides complete and uniform protection to the soil ball when closed.

[0038] Working principle: When in use, the hydraulic telescopic arm 4 first pushes the closed left cover 81 and right cover 6 to the location of the sapling to be transplanted, so that the soil ball of the sapling is located in the cylindrical inner cavity formed after the left cover 81 and right cover 6 are closed. The hydraulic gripper 7 is activated to clamp and fix the soil ball. The hydraulic cylinder 3 is activated, and its movable end extends to drive the sliding arm 2 to slide down along the inner wall of the connecting frame 1, driving the entire working part to descend vertically. During the descent, the convex ball 85 on the fixed plate 84 is embedded in the spiral groove 83 on the outer surface of the left cover 81 and the right cover 6. Since the convex ball 85 is fixed in the horizontal direction, the spiral groove 83 descends with the cover. Under the guidance of the spiral groove 83, the left cover 81 and the right cover 6 generate a rotational motion around their own axis while descending, that is, spiral descent. The flexible arc-shaped cover 91 fixed at the bottom of the left cover 81 and the right cover 6 rotates and descends with the cover. When the flexible arc-shaped cover 91 contacts the bottom of the planting hole, it undergoes elastic deformation to support the bottom of the soil ball. At the same time, the groove 92 scrapes the soil around the hole into it during the rotation and carries it upward with the rotation of the cover. The soil is squeezed out into the annular gap around the soil ball along the gradually shallowing groove 92, thus achieving auxiliary soil covering. When the flexible arc-shaped cover 91 encounters uneven resistance, the T-shaped ring 103 slides along the arc rod 102 in the sliding groove 101 and compresses or stretches the spring 104, causing the flexible arc-shaped cover 91 to produce adaptive deflection. When the hydraulic cylinder 3 drives the sliding arm 2 to continue descending to the predetermined planting depth, the hydraulic gripper 7 releases the soil ball, the movable end of the hydraulic cylinder 3 retracts, the sliding arm 2 drives the working parts to move upward, and the left cover 81 and the right cover 6, with the cooperation of the convex ball 85 and the spiral groove 83, exit the planting hole in a spiral manner, completing the transplanting and placement of a sapling.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
