Description

Technical Field

[0001] This invention belongs to the field of forestry seedling transplanting technology, specifically a root soil protection device for forestry seedling transplanting. Background Technology

[0002] An existing patent (patent publication number: CN114223492A) discloses a root protection device for transplanting forest trees. Its structure includes a connecting shaft, a collar, an adjusting buckle, a through column, a telescopic clamp, and a protective net. The connecting shaft is connected to the telescopic clamp via the adjusting buckle. The through column is inserted between the telescopic clamps and a protective net is provided. The assisting body is provided with a relief support and an auxiliary cover. The relief support and the auxiliary cover cooperate on the inclined plate. When the soil in the root moves and deforms towards the synchronously shrinking and deforming protective net, it will push the deformed protective net to compress onto the auxiliary cover along with the root. This causes the auxiliary cover to expand outward through the clamping handle, the inclined plate, and the hook. With the assistance of the pressure roller and the relief support, the soil on the protective plate is gathered into a bundle at the point of concentrated deformation of the protective net. The whole is maintained in a tight and fixed support within the protective net.

[0003] In the process of implementing the above solution, the following problems were found in the existing technology: the existing root soil protection device requires the seedling to be lifted before it can be installed at the root of the seedling. However, lifting the seedling can easily cause the soil at the root of the seedling to fall off, resulting in a low survival rate of the transplanted seedling. Summary of the Invention

[0034] The protective unit 2 includes a connecting and fixing unit 1 and a connecting plate 21 symmetrically arranged at the bottom of the first limiting plate 11 and the second limiting plate 12. The connecting plate 21 has a second receiving groove 22 horizontally symmetrically arranged to accommodate the first limiting block 23. The first limiting block 23 is arranged in the second receiving groove 22 to drive the rack 24 to move. The rack 24, which drives the adjusting gear 261 to rotate, is fixedly connected to the bottom of the first limiting block 23. A connecting rope 25 is arranged on one side of the first limiting block 23 to drive the first limiting block 23 to move along the second receiving groove 22. One end of the connecting rope 25 is fixedly connected to the first limiting block 23. A bearing component 26 for supporting the seedling is arranged at the bottom of the first limiting block 23.

[0035] A limiting strip 111 is fixedly connected to one end of the first limiting plate 11 to limit its position. A receiving hole 121 is horizontally opened at one end of the second limiting plate 12 to accommodate the limiting strip 111. A limiting gear 122 is installed inside the receiving hole 121 to fix the limiting strip 111, and the limiting gear 122 meshes with the limiting strip 111. A limiting shaft 123 is provided at the bottom of the limiting gear 122 to limit the adjusting rod 127. The 23 is hollow. The inner wall of the limiting shaft 123 is vertically provided with a first limiting groove 124 and a second limiting groove 125 for limiting the second limiting block 128. The inner wall of the limiting shaft 123 is horizontally provided with a third limiting groove 126 for limiting the second limiting block 128. One end of the third limiting groove 126 is connected to the first limiting groove 124, and the other end of the third limiting groove 126 is connected to the second limiting groove 125.

[0036] An adjusting rod 127 for adjusting the position of the limiting gear 122 is provided inside the limiting shaft 123. One end of the adjusting rod 127 vertically passes through the second limiting plate 12. The adjusting rod 127 and the second limiting plate 12 are connected by a bearing. A second limiting block 128 for limiting the adjusting rod 127 is symmetrically fixedly connected to the adjusting rod 127. The second limiting block 128 is located in the first limiting groove 124. One end of the adjusting rod 127 is hollow. A first elastic element 129 for driving the adjusting rod 127 to reset is provided inside the adjusting rod 127. One end of the first elastic element 129 is fixedly connected to the adjusting rod 127. The other end of the first elastic element 129 is attached to the bottom of the inner wall of the receiving hole 121. The adjusting rod 127 vertically passes through the limiting gear 122 and the second limiting plate 12. The adjusting rod 127 and the second limiting plate 12 are fixedly connected.

[0037] A connecting hole 27 is vertically provided on the inner wall of the bottom of the slide 15, connecting the slide 15 and the second receiving groove 22. The second receiving groove 22 is connected to the slide 15 through the connecting hole 27. One end of the connecting rope 25 passes through the connecting hole 27 and is fixedly connected to the slider 16. A limiting hole 28 is horizontally provided on one side of the first limiting block 23 to accommodate the second elastic member 29. The second elastic member 29 is provided in the limiting hole 28 to drive the first limiting block 23 to reset. One end of the second elastic member 29 is fixedly connected to the inner wall of the limiting hole 28, and the other end of the second elastic member 29 extends out of the limiting hole 28. One end of the second elastic member 29 extending out of the limiting hole 28 is fixedly connected to the inner wall of the second receiving groove 22.

[0038] It should be noted that the first elastic element 129 and the second elastic element 29 are preferably springs or dampers. Figure 5 , Figure 6 , Figure 8 and Figure 9 The example below is a spring.

[0039] The supporting component 26 includes an adjusting gear 261 located at the bottom of the first limiting block 23, which drives the adjusting column 263 to rotate. The adjusting gear 261 meshes with the rack 24. An adjusting shaft 262 is horizontally arranged through the adjusting gear 261 to limit the adjustment gear 261. The adjusting shaft 262 and the adjusting gear 261 are connected by bearings. Both ends of the adjusting shaft 262 are fixedly connected to the connecting plate 21. An adjusting column 263 that rotates with the adjusting gear 261 is fixedly connected to the adjusting gear 261. A supporting stalk 264 that supports the sapling is fixedly connected to the bottom end of the adjusting column 263.

[0040] The load-bearing assembly 26 also includes a first telescopic rod 265 fixedly connected to the bottom of the connecting plate 21 to drive the support column 266 to rise and fall. The output end of the first telescopic rod 265 is fixedly connected to the support column 266 that supports the connecting plate 21. The support column 266 is hollow. Inside the support column 266, there is a second telescopic rod 267 that drives the rotating wheel 269 to move along the inner wall of the support column 266. The output end of the second telescopic rod 267 is horizontally connected to a connecting shaft 268 that limits the rotation of the rotating wheel 269. The connecting shaft 268 is connected to the output end of the second telescopic rod 267 through a bearing. The two ends of the connecting shaft 268 are connected to the rotating wheel 269 through universal joints, which enables the device to move.

[0041] It should be noted that the first telescopic pole 265, the second telescopic pole 267, and the third telescopic pole 18 are all electric telescopic poles.

[0042] like Figures 1-11 As shown in this embodiment, when the seedling needs to be transplanted, the second telescopic rod 267 is activated, so that the output end of the second telescopic rod 267 drives the rotating wheel 269 to extend out of the support column 266, so that the rotating wheel 269 contacts the ground, thereby enabling the operator to push the device to the side of the seedling that needs to be transplanted.

[0043] When the device moves to the sapling, it separates the first limiting plate 11 and the second limiting plate 12, so that the sapling is located between the first limiting plate 11 and the second limiting plate 12. Then, the second telescopic rod 267 is activated. The second telescopic rod 267 drives the first limiting plate 11, the second limiting plate 12 and the connecting plate 21 to rise or fall, so that the device can adjust the clamping position according to the height of the sapling, so that the device can better protect the soil around the roots of the sapling.

[0044] When the clamping position is adjusted, the first limiting plate 11 and the second limiting plate 12 are joined together, so that the limiting strip 111 enters the receiving hole 121. Press the adjusting rod 127. With the second limiting block 128 limiting it, the adjusting rod 127 descends along the first limiting groove 124. When the second limiting block 128 moves to the bottom of the first limiting groove 124, the limiting gear 122 meshes with the limiting strip 111. Rotate the adjusting rod 127 so that the second limiting block 128 moves along the third limiting groove 126, thereby driving the limiting gear 122 to rotate, and then driving the limiting strip 111 to move. When the second limiting block 128 moves to the bottom of the second limiting groove 125, release the adjusting rod 127. The adjusting rod 127 rises under the action of the first elastic member 129, thereby fixing the limiting gear 122 and the limiting strip 111, and thus locking the first limiting plate 11 and the second limiting plate 12.

[0045] After the first limiting plate 11 and the second limiting plate 12 are locked, the second telescopic rod 267 is closed so that the support column 266 contacts the ground, preventing the device from moving during the process of carrying the sapling and causing damage to the sapling. The third telescopic rod 18 is then activated, causing the third telescopic rod 18 to drive the slider 16 to move along the slide groove 15. This causes the slider 16 to drive the airbag 14 to extend out of the first receiving groove 13, inflating the airbag 14 so that it can clamp the trunk of the sapling, thereby stabilizing the sapling and enabling the device to clamp saplings of different trunk thicknesses.

[0046] As the slider 16 moves along the groove 15, the slider 16 pulls the first limiting block 23 along the second receiving groove 22 via the connecting rope 25, thereby driving the adjusting gear 261 to rotate via the rack 24. The adjusting gear 261 drives the bearing bag 264 to rotate via the adjusting column 263, so that the bearing bag 264 supports the seedling while protecting the soil at the root of the seedling, preventing the soil at the root of the seedling from falling off during transplanting and causing the seedling to die.

[0047] Activate the first telescopic rod 265, which causes the first limiting plate 11, the second limiting plate 12 and the connecting plate 21 to rise, moving the sapling out of the pit. Activate the second telescopic rod 267, which causes the rotating wheel 269 to contact the ground, making it easier for operators to transport the sapling.

[0048] When the sapling is transported to the planting location, the second telescopic rod 267 is closed, allowing the support column 266 to contact the ground. The first telescopic rod 265 is activated, causing the carrying bag 264 to move the sapling roots into the transplanting pit. The third telescopic rod 18 is closed, and the first limiting block 23 is reset under the action of the second elastic element 29. The first limiting block 23 drives the slider 16 to reset via the connecting rope 25, which in turn drives the airbag 14 to reset, thereby releasing the clamp on the sapling. At the same time, the carrying bag 264 gradually opens, placing the sapling roots into the transplanting pit.

[0049] After the staff covered the roots of the sapling with soil, they separated the first limiting plate 11 and the second limiting plate 12 to complete the transplanting of the sapling.

[0050] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
