Description

Technical Field

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

[0002] Currently, forestry seedling transplantation has developed a mature technical system. During the transplantation process, professional machinery and equipment such as hydraulic four-lobed tree transplanters and tracked root ball carrying machines are widely used. They can efficiently and accurately complete tasks such as root ball excavation, hoisting and transportation, significantly reducing damage to the seedling root system.

[0003] Existing transplanting devices involve directly inserting a shovel into the soil during root ball excavation, then lifting the root ball and seedling. This can easily pull on the seedling's root system, damaging both the root ball and the seedling, thus affecting the survival rate. Furthermore, the strong pressure exerted on the soil when the shovel penetrates deeply makes it difficult for the root ball to maintain its shape, compromising its ability to protect the seedling's roots. In addition, the support provided to the seedling during excavation is poor, leading to tilting.

[0004] To address the above problems, this invention provides a forestry seedling transplanting device to solve these problems. Summary of the Invention

[0030] Furthermore, preferably, a limiting cylinder is fixed at the position corresponding to the nut on the outer wall of the sliding plate, and the output end of the limiting cylinder extends into the sliding plate and contacts and limits the movement of the nut on the outer wall.

[0031] Compared with the prior art, the present invention provides a forestry seedling transplanting device, which has the following beneficial effects:

[0032] In this invention, when transplanting seedlings, the area around the seedling is first excavated vertically using a digging shovel to form a columnar soil column.

Furthermore, during excavation, multiple clamping components can stagger and clamp the seedling branches, more effectively resisting torques from different directions and enhancing the clamping effect.

[0038] Reference Figures 1-4 The present invention provides a technical solution: a forestry seedling transplanting device, comprising:

[0039] The vehicle body has a lifting device fixed at one end;

[0040] Connector 1 is fixed to the output end of the lifting device;

[0041] A positioning ring is rotatably disposed at the end of the connecting seat 1 away from the lifting device, and the positioning ring includes a positioning ring 2 and a positioning ring 3. The positioning ring 2 and the positioning ring 3 are hinged at one end, and an opening and closing cylinder 4 is installed at the hinge position.

[0042] The transplanting components 5 are configured in three, arranged circumferentially on the positioning ring;

[0043] Drive component 6 is installed on the connecting seat 1 and the positioning ring;

[0044] Clamping components 7, at least two in number, are slidably disposed on the drive component 6.

[0045] It should be noted that the clamping components 7 are at different heights, thereby clamping the seedling branches in a staggered manner, realizing the asymmetrical layout to disperse the force transmission, reducing the concentration of local forces, and improving the clamping effect.

[0046] In this embodiment, the transplanting component 5 includes:

[0047] The lifting frame 51 is hinged at one end to the positioning ring, and a lifting cylinder is fixed inside it.

[0048] The adjusting cylinder 52 is hinged at one end to the lifting frame 51 and at the other end to the positioning ring;

[0049] The excavator 53 is slidably mounted on the lifting frame 51 and connected to the output end of the lifting cylinder.

[0050] In a preferred embodiment, the side wall of the shovel 53 is provided with a cutting blade 54, and when the shovel 53 is in a vertical state, the rotation trajectory of the plurality of shovels 53 is circular.

[0051] During excavation, the digging shovel 53 initially points vertically downwards. The lifting cylinder then guides the shovel 53 into the soil. The drive assembly 6 then causes the shovel 53 to reciprocate, cutting the seedling roots and preventing them from being pulled. After the initial excavation, the soil around the seedling forms a columnar structure, with the bottom of the columnar structure connected to the soil. This completes the initial excavation, preventing the excavation point from being too close to the root ball and compressing it, thus affecting soil compaction. The shovel 53 then adjusts its angle by adjusting the cylinder 52, causing it to retract as it slides, thus trimming the columnar soil and completing the root ball excavation, reducing the pressure on the root ball.

[0052] In this embodiment, the driving component 6 includes:

[0053] A fixed base 61 is fixed to the upper end of the connecting base 1, and a drive motor is fixed to the bottom of the connecting base 1;

[0054] The drive gear 62 is rotatably mounted on the fixed base 61 and is driven by a drive motor;

[0055] Half gear 63 is fixed on the positioning ring and hinged to the drive gear 62;

[0056] The guide plate 65 is fixed to one end of the fixed base 61 near the half gear 63.

[0057] In other words, by driving the half gear 63 to rotate through the drive gear 62, and driving the positioning ring to rotate, the position of the digging shovel 53 is adjusted to complete the cutting of the root system and the trimming of the soil ball.

[0058] In a preferred embodiment, the top of the half gear 63 is provided with a guide groove 64, and the lower end face of the guide plate 65 is rotatably provided with a plurality of guide wheels 66, which are rolled within the guide groove 64.

[0059] The guide groove 64 and guide wheel 66 of the drive gear 62 can guide the half gear 63, thereby enabling the half gear 63 to mesh and transmit power better with the drive gear 62.

[0060] In a preferred embodiment, a threaded rod 68 is rotatably disposed on the fixed base 61, the threaded rod 68 is fixedly connected to the drive gear 62, and a guide rod 67 is fixedly disposed on the upper end face of the guide plate 65.

[0061] In a preferred embodiment, the clamping assembly 7 includes:

[0062] A sliding plate 71 has a sliding groove 72 at one end, which is slidably mounted on a guide rod 67. A nut 73 is rotatably mounted inside the other end of the sliding plate 71, and the nut 73 is threadedly connected to a threaded rod 68.

[0063] The clamping rod 75 is hinged to the guide rod 67 and also hinged to the sliding plate 71;

[0064] The clamping cylinder 76 is hinged at one end to the sliding plate 71 and at the other end to the clamping rod 75;

[0065] A flexible wheel 77 is rotatably disposed at the end of the clamping rod 75 away from the sliding plate 71, and a torsion spring is provided between the wheel and the clamping rod 75.

[0066] The clamping plate 78 has an arc-shaped structure and is fixed to the flexible wheel 77.

[0067] In a preferred embodiment, a limiting cylinder 74 is fixed at a position corresponding to the outer wall of the sliding plate 71 and the nut 73. The output end of the limiting cylinder 74 extends into the sliding plate 71 and contacts and limits the movement of the outer wall of the nut 73.

[0068] In other words, when the output end of the limiting cylinder 74 contacts and limits the nut 73, the threaded rod 68 rotates, and the nut 73 slides up and down through the threaded connection, thereby adjusting the height of the clamping plate 78 to perform staggered clamping for seedlings of different heights. When the output end of the limiting cylinder 74 does not contact the nut 73, the nut 73 can rotate within the sliding plate 71. At this time, the threaded rod 68 rotates, and the nut 73 rotates synchronously with the threaded rod 68, avoiding vertical displacement during clamping operations and improving the clamping effect.

[0069] Specifically, when transplanting seedlings, the digging shovel 53 is used to initially excavate around the seedling in a vertical position to form a columnar soil. During excavation, the digging shovel 53 is rotated back and forth by the drive component 6 to facilitate root cutting. Afterward, the digging shovel 53 is adjusted and retracted to trim the columnar soil, forming a semi-circular soil ball. This reduces the squeezing pressure on the soil ball during excavation, avoids changing the compaction of the soil inside the soil ball, and prevents it from affecting the survival rate. Furthermore, during excavation, multiple clamping components 7 can clamp the seedling branches in a staggered manner, more effectively resisting torques from different directions and enhancing the clamping effect.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
