Description

Technical Field

[0001] This utility model relates to the field of fruit tree cultivation technology, specifically to a seedling lifter for peach tree planting. Background Technology

[0002] In the process of planting fruit trees, it is usually necessary to transplant seedlings. The existing seedling transplanting technology mainly uses shovels and buckets. When working, a deep trench is dug around the peach seedling with a shovel. When the trench is dug to a certain depth, the soil ball of the peach seedling root system is lifted and the soil ball is separated from the surrounding soil.

[0003] Chinese Patent No. CN218736356U discloses a seedling lifter for peach tree planting, comprising two main plates, both of which are arc-shaped. Each main plate has a groove on one side, and the other sides of the two main plates are in contact. Sub-plates are slidably connected to each main plate within the grooves. The adjacent sides of the two sub-plates are rotatably connected. A fixing plate is fixedly connected to the exterior of one side of each main plate. Several connecting blocks are fixedly connected to the top of one side of each main plate, and threaded blocks are fixedly connected to the top of each connecting block. Each main plate has a handle on its top, and a support rod is fixedly connected to the middle of the bottom of each handle. The bottom of each support rod is threadedly connected to the corresponding threaded block. This invention, by setting up main plates, sub-plates, fixing plates, connecting blocks, threaded blocks, support rods, limiting rods, limiting blocks, rotating plates, rotating shafts, and reinforcing frames, provides a simple, reliable, effective, stable, and practical device.

[0004] However, the above technical solution only uses a main board, sub-board, fixing board, connecting block, threaded block, support rod, limit rod, limit block, rotating plate, rotating shaft, and reinforcing frame to transplant peach seedlings. However, when using this structure, the main board and sub-board used for cutting can only move vertically. Workers also need to exert effort to pull the cylindrical soil clods upwards, which is not only laborious but also easily damages the seedlings. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a seedling lifter for peach tree planting.

[0006] The technical solution of this utility model is as follows: A seedling lifter for peach tree planting includes a limiting cylinder composed of a first arc-shaped plate and a second arc-shaped plate, which are hinged to each other. Both the first and second arc-shaped plates have multiple notches. A cutter, the number of which corresponds to the notches on the first and second arc-shaped plates, is rotatably connected within the notches, and a locking groove is provided on the side wall of the cutter. Two support rods are arranged in parallel, each connected to the first and second arc-shaped plates respectively, and a handle is attached to each support rod. The gripping assembly is connected to the limiting cylinder and consists of a moving block, a pressing plate, and a wedge block. There are two symmetrically arranged moving blocks, both of which are arc-shaped. The moving blocks are slidably connected to the support rod and rotatably connected to each other. The number of pressing plates corresponding to the number of cutters is connected to the moving blocks at both ends. The outer walls of the pressing plates are connected to the wedge blocks. When the gripping assembly is in use, the moving blocks drive the pressing plates and wedge blocks to move linearly along the support rod. The wedge blocks push the cutter to rotate and form a fixed angle with the locking groove, so that the cutter forms a conical receiving space.

[0007] Preferably, the cutter consists of a cutter head and a connecting plate. The connecting plate and the cutter head form a T-shaped structure. The connecting plate is rotatably connected to the notch. One end of the connecting plate is connected to the cutter head, and a locking groove is formed on the connecting plate.

[0008] Preferably, both the first and second arc-shaped plates are connected to foot pedals, and each foot pedal is provided with an anti-slip strip.

[0009] Preferably, a magnetic attracting element is connected to the first arc-shaped plate, and a magnetic attachment is connected to the second arc-shaped plate, with the magnetic attracting element and the magnetic attachment being magnetically connected.

[0010] Preferably, the gripping assembly also includes elastic elements, the number of which corresponds to the number of moving blocks. The elastic elements are sleeved on the outside of the support rod, and both ends of the elastic elements are connected to the moving block and the limiting cylinder, respectively.

[0011] Preferably, the cutting blades are coated with polytetrafluoroethylene.

[0012] Preferably, both the first and second arc-shaped plates are provided with scales.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: In this invention, multiple circularly arrayed cutters are used to cut the soil and the root system of the seedlings. After the cutting is completed, the cutters rotate around the support shaft under the action of the moving block, the squeezing plate and the wedge block. The rotating cutters form a conical structure to grasp and squeeze the soil column, reducing the connection force between the soil and making it easier to pull out the soil column and the seedling.

[0015] Example 1, as Figures 1-4 As shown, this utility model proposes a seedling lifter for peach tree planting, comprising a first arc-shaped plate 1, a second arc-shaped plate 2, a cutter 3, a support rod 5, and a gripping assembly. The limiting cylinder is composed of the first arc-shaped plate 1 and the second arc-shaped plate 2, which are hinged to each other. Both the first arc-shaped plate 1 and the second arc-shaped plate 2 have multiple notches. The number of cutters 3 corresponds to the number of notches on the first arc-shaped plate 1 and the second arc-shaped plate 2. The cutters 3 are rotatably connected within the notches. A locking groove 4 is provided on the side wall of the cutter 3. A support shaft is connected to the notch, and the cutter 3 has a through hole connected to the support shaft. Two support rods 5 are arranged in parallel, and the two support rods 5 are respectively connected to the first arc-shaped plate 1. Handles 6 are connected to support rods 5 on arc plate 1 and second arc plate 2. The gripping assembly is connected to the limiting cylinder. The gripping assembly consists of moving blocks 7, extrusion plates 8 and wedge blocks 9. Two moving blocks 7 are symmetrically arranged. The moving blocks 7 are arc-shaped and are slidably connected to support rods 5. The moving blocks 7 are rotatably connected to each other. The number of extrusion plates 8 corresponding to the number of cutters 3 are connected to the moving blocks 7 at both ends. The outer walls of the extrusion plates 8 are connected to wedge blocks 9. When the gripping assembly is in use, the moving blocks 7 drive the extrusion plates 8 and wedge blocks 9 to move linearly along support rods 5. The wedge blocks 9 push the cutter 3 to rotate and form a fixed angle with the locking groove 4. The cutter 3 forms a conical receiving space. The cutter 3 consists of a cutter head 10 and a connecting plate 11. The connecting plate 11 and the cutter head 10 form a T-shaped structure. The connecting plate 11 is rotatably connected to the notch. One end of the connecting plate 11 is connected to the cutter head 10. The engaging groove 4 is opened on the connecting plate 11. Both the first arc-shaped plate 1 and the second arc-shaped plate 2 are connected to foot pedals 12, and both foot pedals 12 are provided with anti-slip strips; the anti-slip strips are made of, but are not limited to, rubber. A magnetic attractor 13 is connected to the first arc plate 1, and a magnetic attachment 14 is connected to the second arc plate 2. The magnetic attractor 13 and the magnetic attachment 14 are magnetically connected. The magnetic attractor 13 is a permanent magnet, and the magnetic attachment 14 is a metal strip containing iron, cobalt and nickel elements.

[0016] Example 2, as Figure 1 As shown, this utility model proposes a seedling lifter for peach tree planting. Compared with Embodiment 1, this embodiment describes the detailed structure of the gripping component. The gripping assembly also includes elastic elements 15, the number of which corresponds to the number of movable blocks 7. The elastic elements 15 are sleeved on the outside of the support rod 5, and the two ends of the elastic elements 15 are respectively connected to the movable block 7 and the limiting cylinder. The elastic elements 15 may be, but are not limited to, springs. All cutters 3 are coated with polytetrafluoroethylene (PTFE); PTFE has a low coefficient of friction, which reduces the obstruction of soil. Both the first arc-shaped plate 1 and the second arc-shaped plate 2 are equipped with scales; the scales on the first arc-shaped plate 1 and the second arc-shaped plate 2 make it easy for staff to observe the current depth of the cutter 3 into the soil, which is convenient for transplanting seedlings of different ages.

[0017] In summary, when using this utility model, the worker grasps handle 6 to bring the equipment close to the sapling, unfolds the first arc plate 1 and the second arc plate 2, and places them on the outside of the sapling. Then, the cutter 3 is brought close to the soil, and the foot steps on pedal 12 to move the cutter 3 down to dig into the soil. When the depth reaches a certain position on the scale, the external force is stopped. At this time, the moving block 7 is stepped on to compress the elastic element 15, which simultaneously moves the squeezing plate 8 and the wedge block 9 down. During the downward movement, the wedge block 9 contacts one end of the cutter 3, i.e., the connecting plate 11, and pushes it to rotate around the support shaft. The angle affects the rotation of the blade 10, changing it from a vertical to an inclined state. Multiple cutters 3 move synchronously to form a conical receiving space. At the same time, after the connecting plate 11 rotates, its locking groove 4 will cooperate with the wedge block 9 when the worker pulls the seedling lifting equipment up. Under the action of gravity, the cutter 3 rotates and resets around the support shaft. The wedge block 9 restricts its movement, thus keeping the wedge block 9 in the locking groove 4. This maintains the structure of multiple cutters 3 gripping the soil, reducing the connection force between soil particles. As the worker pulls the handle 6, the soil column and seedling can be lifted out.

[0018] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
