Description

Technical Field

[0001] This utility model relates to the field of seedling transplantation technology, and more specifically, to a soil ball protection device for transplanting seedlings in reserve forests. Background Technology

[0002] Seedlings refer to young seedlings or saplings of woody plants used in forestry production, ecological afforestation, and landscaping. They typically include trees (such as pine, poplar, and camphor) and shrubs (such as holly and lilac). Based on their cultivation purpose and specifications, forest seedlings can be categorized into seedlings (grown from seeds), cuttings (grown from branch cuttings), and grafted seedlings (grown from grafting). Their core function is to construct forest ecosystems, improve the environment, or enhance landscape effects.

[0003] Among the root systems of seedlings, the fibrous roots (absorbent roots) are responsible for absorbing water and nutrients. These roots are delicate and fragile, and extremely sensitive to environmental changes. If they are not transplanted with a soil ball, the roots are directly exposed to the air and are prone to rapid water loss due to sun exposure and wind. At the same time, they are also easily broken by tools during transportation or planting, which leads to a decrease in the survival rate of seedlings. Therefore, a soil ball protection device for transplanting seedlings in reserve forests is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a soil ball protection device for transplanting seedlings in reserve forests, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a protective device with soil ball for transplanting seedlings in reserve forests, including a support cylinder, on which a protective component is provided;

[0006] The protective assembly includes a limiting plate disposed at the top of the inner cavity of the support cylinder, a tray disposed at the bottom of the limiting plate, a placement plate slidably connected to the limiting plate, and the bottom end of the placement plate being fixed to the tray.

[0007] A spring is provided at the bottom of the tray, the spring is located at the bottom of the inner cavity of the support cylinder, and a number of first baffles are distributed on the top surface of the support cylinder.

[0008] Optionally, in one possible implementation, a plurality of upper extension rods are fixedly provided on the outer side of the limiting plate, and a hinge rod is respectively hinged to one end of each upper extension rod, and a seedling-supporting rod is respectively hinged to one end of each hinge rod. A limiting groove is opened at the top of the seedling-supporting rod, and a second baffle is provided on one side of the seedling-supporting rod. A plurality of lower extension rods are fixedly provided on the outer side of the tray, and one end of each lower extension rod extends to the bottom end of the corresponding seedling-supporting rod and is hinged to the seedling-supporting rod. A plurality of sliding grooves are opened through the outer side of the support cylinder, and each upper extension rod and lower extension rod is located in the sliding groove. The lower extension rod is slidably connected to the sliding groove. A plurality of first baffles are distributed circumferentially along the axial direction of the support cylinder, and the first baffles are located on the outer side of the placement plate.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] A comprehensive root ball protection system is formed through a three-layer protective structure consisting of a support plate, a second inner enclosure, and a first outer enclosure. The support plate directly supports the bottom of the root ball, preventing it from collapsing due to gravity; the second enclosure fits tightly against the sides of the root ball for precise wrapping; and the first enclosure blocks external impacts. This triple protection works synergistically to effectively prevent the root ball from loosening and falling off during transportation and handling, maximizing the protection of delicate and fragile roots. This solves the core problems of easily damaged roots and rapid water loss in traditional transplanting, significantly improving the survival rate of transplanted seedlings.

[0011] By utilizing a linkage mechanism triggered by the weight of the root ball, the device can achieve adaptive fixing of seedlings of different sizes. When the pressure of the root ball pushes the tray downward, the seedling support rod automatically moves towards the trunk through the transmission of the lower extension rod and the hinge rod, and the top limiting groove precisely fits the trunk; at the same time, the reverse elastic force of the spring keeps the clamping force stable, which not only avoids shaking and collision during seedling transportation, but also prevents bark scratches through the rubber buffer pad in the limiting groove. This structure requires no manual adjustment and is suitable for various seedling types such as seedlings grown from seed, cuttings, and grafted seedlings, balancing fixing reliability and ease of operation.

[0012] Furthermore, the spring's expansion and contraction quickly absorbs the impact force, causing the placement plate and root ball to buffer synchronously, minimizing the direct impact of vibration on the root system. At the same time, the spring force keeps the clamping force of the support pole on the trunk dynamically balanced, avoiding relative friction between the seedling and the device, providing continuous and stable protection for the root system and root ball, making it particularly suitable for seedling transportation scenarios involving long distances and complex road conditions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses a soil ball protection device for transplanting reserve forest seedlings, which aims to solve the problems of the soil ball of seedlings with soil balls being easily loose and the root system being easily damaged during the existing seedling transplanting process, and the main trunk of the seedling lacking stable support, resulting in a reduced survival rate of seedlings during transportation and planting.

[0021] Specifically, the protective device includes a support cylinder 1, which is a cylindrical structure with an open top and a closed bottom. Its inner cavity is used to accommodate the roots of the seedling with its root ball. Several evenly distributed circumferential grooves 13 are opened through the outer wall, extending axially along the support cylinder 1 to guide the sliding of subsequent components. The support cylinder 1 is equipped with protective components for protecting the root ball and positioning the seedling.

[0022] The protective assembly includes a limiting disc 2 located at the top of the inner cavity of the support cylinder 1. The limiting disc 2 is a circular disc with a diameter slightly smaller than the inner diameter of the support cylinder 1, and can slide up and down along the inner cavity of the support cylinder 1. A tray 3 is located at the bottom of the limiting disc 2. The tray 3 is a circular tray coaxial with the limiting disc 2, and its diameter is adapted to the limiting disc 2. A placement plate 4 is slidably connected to the limiting disc 2 for directly supporting the roots of seedlings with soil balls. The bottom end of the placement plate 4 is fixed to the tray 3 by bolts. When the tray 3 moves up and down, it can drive the placement plate 4 to slide synchronously along the radial direction of the limiting disc 2, thereby adapting to soil balls of different diameters.

[0023] A spring 12 is welded to the bottom of the pallet 3. The end of the spring 12 away from the pallet 3 is fixed to the bottom of the inner cavity of the support cylinder 1. When the spring 12 is in its natural state, it can support the pallet 3 and the limiting plate 2 in the upper part of the inner cavity of the support cylinder 1. Several first baffles 5 are welded to the top surface of the support cylinder 1, which are evenly distributed along the axial circumference. The first baffles 5 are arc-shaped steel plates and are located outside the placement plate 4. They are used to provide initial protection for the soil ball from the outside and prevent external collisions from directly affecting the soil ball during transportation.

[0024] Several upper extension rods 11, corresponding one-to-one with the sliding grooves 13, are welded to the outer side of the limiting plate 2. The upper extension rods 11 extend horizontally to the corresponding sliding grooves 13. The end of each upper extension rod 11 away from the limiting plate 2 is hinged to a hinge rod 6. The end of the hinge rod 6 away from the upper extension rod 11 is hinged to a seedling support rod 7. The seedling support rod 7 is a vertically arranged long rod used to press the main trunk of the seedling from the side.

[0025] The top of the support pole 7 has an arc-shaped limiting groove 8 along its length. The inner wall of the limiting groove 8 is lined with a rubber buffer pad, which can fit the main trunk of the seedling while avoiding damage to the bark. An arc-shaped second baffle 9 is welded to the side of the support pole 7 away from the center of the support cylinder 1. The second baffle 9 is located on the outer side of the first baffle 5 and is adapted to the outer wall of the placement plate 4, so that the placement plate 4 and the first baffle 5 can form a multi-layer soil ball protection structure.

[0026] Several lower extension rods 10, corresponding one-to-one with the upper extension rods 11, are welded to the outside of the tray 3. The lower extension rods 10 extend horizontally into the corresponding slide grooves 13 and slide in connection with the slide grooves 13. The end of each lower extension rod 10 away from the tray 3 extends to the bottom end of the corresponding seedling support rod 7 and is hinged to the seedling support rod 7 through a hinge to form a linkage support structure.

[0027] The specific working principle is as follows: When transplanting seedlings, the roots of the seedlings with soil balls are first placed on the placement plate 4. The weight of the soil ball will exert downward pressure on the placement plate 4, thereby pushing the tray 3 downward along the inner cavity of the support cylinder 1. At this time, the spring 12 at the bottom of the tray 3 is compressed and generates a reverse elastic force. During the downward movement of the tray 3, the lower extension rod 10 on its outer side will slide downward synchronously along the slide groove 13. Since the lower extension rod 10 is hinged to the bottom end of the support rod 7, the downward movement of the lower extension rod 10 will cause the bottom end of the support rod 7 to deflect outward towards the outside of the support cylinder 1. At the same time, the support rod 7 is connected to the upper extension rod 11 through the hinge rod 6. Under the limiting action of the upper extension rod 11, the entire support rod 7 will move towards the center of the support cylinder 1.

[0028] As the support pole 7 approaches, its top limiting groove 8 gradually conforms to the main trunk of the seedling, clamping and positioning the main trunk under the protection of the rubber buffer pad, preventing the seedling from shaking during transportation. At the same time, the second baffle 9 on the outside of the support pole 7 moves towards the outside of the root ball, working in conjunction with the placement plate 4 to tightly wrap the root ball from the outside. Meanwhile, the first baffle 5 on the top of the support cylinder 1 protects the root ball from the outside, forming a three-layer protective structure of inner, middle and outer layers, effectively preventing the root ball from loosening and falling off.

[0029] When encountering bumps and vibrations during transportation, the spring 12 will absorb the impact force through its own expansion and contraction deformation, causing the tray 3 and the placement plate 4 to move up and down for buffering, reducing the direct impact of vibration on the soil ball and root system; at the same time, the clamping force of the seedling support pole 7 on the main trunk will remain stable under the elastic force of the spring 12, preventing the seedling from being damaged due to relative friction with the device caused by vibration.

[0030] When planting, simply lift the seedling upwards. The pressure of the soil ball on the placement plate 4 disappears, the spring 12 returns to its natural state and pushes the tray 3 and the limiting plate 2 upwards. The lower extension rod 10 slides upwards along the sliding groove 13, causing the seedling support rod 7 to open outwards. The limiting groove 8 and the second enclosure plate 9 release the constraint on the main trunk and soil ball of the seedling, making it easy to take out the seedling for planting. The whole process is convenient to operate and has a significant protective effect on the seedling.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
