Description

Technical Field

[0001] This utility model relates to the field of seedling transplanting technology, specifically a seedling extractor for transplanting forest tree seedlings. Background Technology

[0002] The seedling picker for forest tree seedling transplantation is a highly efficient tool designed specifically for forest tree seedling transplantation operations. It can greatly reduce damage to the seedling root system, maintain the integrity of the root system, and significantly improve the survival rate of seedlings after transplantation. Moreover, compared with the traditional manual seedling picking method, its work efficiency is greatly improved, reducing labor costs and providing strong support for large-scale forest tree seedling transplantation work.

[0003] Currently, when transplanting tree seedlings, it is necessary to cut off excess roots inside the soil and remove the seedlings along with the soil attached to them from the planting soil to improve the survival rate. However, existing seedling extractors for tree transplanting cannot effectively cut off excess roots at the bottom. During the process of removing the seedlings from the soil, pulling can damage the roots, and the soil on the roots is also easily lost, affecting the survival rate of the seedlings. Therefore, we propose a seedling extractor for tree transplanting. Utility Model Content

[0004] The purpose of this utility model is to provide a seedling extractor for transplanting forest tree seedlings. During the transplanting process, it can cut off excess roots at the bottom, avoiding root damage and soil loss caused by pulling during seedling extraction, thus improving the survival rate of seedlings. This solves the problem that existing seedling extractors for transplanting forest tree seedlings cannot effectively cut off excess roots at the bottom, and that pulling during seedling extraction can damage roots and cause soil loss, affecting the survival rate of seedlings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seedling taker for transplanting forest tree seedlings, comprising a seedling taker body, wherein a column and a fixing tube are fixedly installed on both sides of the outer surface of the seedling taker body, a fixing ring is fixedly connected to the lower surface of the column, and a cutting edge is provided on the lower surface of the fixing ring near the edge, a rotating shaft is rotatably installed inside the fixing tube and passes through the fixing tube, a rotating ring is fixedly installed on the outer surface of the rotating shaft and is located between the fixing ring and the seedling taker body, and a cutting edge is provided on both the outer surface and the inner wall of the rotating ring.

[0006] Preferably, a handwheel is fixedly connected to the top of the rotating shaft.

[0007] Preferably, sliding sleeves are symmetrically fixedly installed on both sides of the inner wall of the seedling tube, and sliding rods are slidably inserted into the two sliding sleeves. A horizontal plate is fixedly connected to the top of the sliding rod, and a lifting pressure ring is fixedly connected to the bottom of the sliding rod.

[0008] Preferably, a lifting slip ring is slidably sleeved on the outer surface of the rotating shaft above the fixed tube, a helical spring is spirally wound on the outer surface of the rotating shaft above the lifting slip ring, a positioning slot is provided on the upper surface of the fixed tube, and a positioning plug is fixedly installed on the lower surface of the lifting slip ring.

[0009] Preferably, a limiting groove is provided on the outer surface of the rotating shaft above the fixed tube, and a protrusion is provided on the inner wall of the lifting slip ring, with the protrusion located inside the limiting groove.

[0010] Preferably, the bottom end of the rotating shaft is rotatably connected to the side of the upper surface of the fixing ring away from the column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a seedling extraction cylinder, a column, a fixing tube, a fixing ring, a cutting edge, a rotating shaft, a rotating ring, and a cutting edge, achieves the effect of cutting off excess roots at the bottom during the transplanting of forest tree seedlings, avoiding root damage and soil loss caused by pulling during seedling extraction, and improving the survival rate of seedlings. The forest tree seedling is inserted into the seedling extraction cylinder, and the seedling extraction cylinder is inserted into the planting soil. The cutting edge on the lower surface of the fixing ring facilitates the insertion of the seedling extraction cylinder into the soil, and at the same time cuts off excess roots on the side of the forest tree seedling roots. Rotating the rotating shaft causes the cutting edge on the inner wall of the rotating ring to cut off excess roots at the bottom, while the cutting edge on the outer side of the rotating ring breaks the soil to facilitate the rotation of the rotating ring and extract the seedling extraction cylinder. The soil squeezed inside the seedling extraction cylinder separates from the planting soil as the seedling extraction cylinder rises, thus removing the forest tree seedling.

[0013] 2. This utility model, by setting up a sliding rod, sliding sleeve, horizontal plate and lifting pressure ring, achieves the effect of facilitating the removal of tree seedlings and soil inside the seedling removal cylinder. When the seedling removal cylinder is inserted into the planting soil, the lifting pressure ring rises relative to the seedling removal cylinder because it is in contact with the soil surface. After the tree seedlings are removed, the lifting pressure ring is pressed down by the horizontal plate and sliding rod, which can push the soil and seedlings inside the seedling removal cylinder to the outside of the seedling removal cylinder.

[0014] 3. This utility model achieves the effect of positioning the rotating ring by using a spiral spring, lifting slip ring, positioning block, positioning slot, limiting slide groove, and protrusion. The rotating shaft drives the rotating ring. When the positioning block moves above the positioning slot, the elastic force of the spiral spring causes the lifting slip ring to descend, and the positioning block is inserted into the positioning slot, which restricts the rotation of the rotating ring and the rotating shaft. At the same time, it also positions the rotating ring, making the rotating ring, seedling tube, and fixing ring coaxial, so that the seedling tube can be inserted into the planting soil or pulled out from the planting soil.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a seedling taker for transplanting forest tree seedlings, including a seedling taker body 3, which is vertically continuous. A column 2 and a fixing tube 7 are fixedly installed on both sides of the outer surface of the seedling taker body 3, respectively. A fixing ring 1 is fixedly connected to the lower surface of the column 2. A cutting edge 9 is provided on the lower surface of the fixing ring 1 near the edge. A rotating shaft 12 is rotatably installed inside the fixing tube 7 and passes through the fixing tube 7. The bottom end of the rotating shaft 12 is rotatably connected to the side of the upper surface of the fixing ring 1 away from the column 2. A rotating ring 10 is fixedly installed on the outer surface of the rotating shaft 12 and is located between the fixing ring 1 and the seedling taker body 3. Both the outer surface and the inner wall of the rotating ring 10 are provided with cutting edges 11. A handwheel 13 is fixedly connected to the top of the rotating shaft 12, and the rotating shaft 12 is rotated by the handwheel 13.

[0024] In use, the tree seedling is inserted into the seedling extraction cylinder 3, which is then inserted into the planting soil. The cutting edge 9 on the lower surface of the fixing ring 1 facilitates the insertion of the seedling extraction cylinder 3 into the soil, while also cutting off excess roots on the sides of the tree seedling. The rotating shaft 12 is rotated, causing the cutting edge 11 on the inner wall of the rotating ring 10 to cut off excess roots at the bottom, while the cutting edge 11 on the outer side of the rotating ring 10 breaks through the soil to facilitate the rotation of the rotating ring 10. The seedling extraction cylinder 3 is then extracted, and the soil squeezed inside the seedling extraction cylinder 3 separates from the planting soil as the cylinder 3 rises, thus removing the tree seedling. During the extraction process, excess roots at the bottom are cut off, preventing root damage and soil loss due to pulling during extraction, thereby improving the seedling survival rate.

[0025] Example 2

[0026] like Figure 1 and Figure 2 As shown, the present invention proposes a seedling taker for transplanting forest tree seedlings. Compared with Embodiment 1, this embodiment also includes symmetrically fixed sliding sleeves 4 on both sides of the inner wall of the seedling taker cylinder 3. Sliding rods 5 are slidably inserted into the two sliding sleeves 4. A horizontal plate 6 is fixedly connected to the top of the sliding rod 5, and a lifting pressure ring 8 is fixedly connected to the bottom of the sliding rod 5.

[0027] In this embodiment, when the seedling tube 3 is inserted into the planting soil, the lifting pressure ring 8 rises relative to the seedling tube 3 because it is in contact with the soil surface. After the seedlings are taken out, the lifting pressure ring 8 is pushed down by the horizontal plate 6 and the sliding rod 5, which pushes the soil and seedlings inside the seedling tube 3 to the outside of the seedling tube.

[0028] Example 3

[0029] like Figure 4 and Figure 5 As shown, the present invention proposes a seedling transplanter for forest tree seedlings. Compared with Embodiment 1, this embodiment further includes a lifting slip ring 17 slidably sleeved on the outer surface of the rotating shaft 12 above the fixed tube 7, a spiral spring 14 spirally wound on the outer surface of the rotating shaft 12 above the lifting slip ring 17, a positioning slot 16 provided on the upper surface of the fixed tube 7, a positioning insert 15 fixedly installed on the lower surface of the lifting slip ring 17, a limiting groove 19 provided on the outer surface of the rotating shaft 12 above the fixed tube 7, and a protrusion 18 provided on the inner wall of the lifting slip ring 17, with the protrusion 18 located inside the limiting groove 19. The protrusion 18 and the limiting groove 19 can limit the lifting slip ring 17, so that the lifting slip ring 17 can only move up and down along the rotating shaft 12 and cannot rotate on its own.

[0030] In this embodiment, the rotating shaft 12 drives the rotating ring 10. When the positioning block 15 moves above the positioning slot 16, the elastic force of the spiral spring 14 causes the lifting slip ring 17 to descend, and the positioning block 15 is inserted into the positioning slot 16, which restricts the rotation of the rotating ring 10 and the rotating shaft 12. At the same time, it also positions the rotating ring 10, making the rotating ring 10, the seedling tube 3 and the fixing ring 1 coaxial, so that the seedling tube 3 can be inserted into the planting soil or pulled out from the planting soil.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
