Description

Technical Field

[0001] This utility model relates to the field of seedling transplanting technology, and in particular to a cutting propagation and burying device. Background Technology

[0002] *Hopea chinensis*, a species of tree in the Dipterocarpaceae family, is a Class I endangered protected plant in China and an indicator plant of seasonal rainforests in southern China, possessing significant ecological value. Its wood is durable, earning it the nickname "ten-thousand-year-old wood." Byproducts include aromatic oils, which can be used in high-end cosmetics and valuable traditional Chinese medicine. Bark extracts have been identified as having therapeutic effects on Alzheimer's disease, giving it immense economic development value. Currently, due to deforestation, the population has drastically declined. Coupled with its short seed lifespan, high inactivation rate, low germination rate, and poor natural regeneration capacity, its survival is precarious. Seed propagation is currently the only method of reproduction for *Hopea chinensis* and even the entire Dipterocarpaceae family. However, seed propagation suffers from low propagation coefficients and slow seedling growth, making it difficult to meet the needs of population recovery.

[0003] To improve seedling survival rates during the propagation of *Hopea stenoptera* through cuttings, a cutting-lifting device is typically used for transplanting. For example, patent CN211607675U discloses an auxiliary seedling-lifting device for landscaping, but this device can only cut the soil around the seedling and cannot simultaneously transplant it. Another example is a forestry seedling-lifting device disclosed in patent CN118901536A. This device uses a second driving component to rotate a shaft, which in turn rotates a disc. As the disc rotates, a limiting rod slides along a groove on the disc, causing the digging claws to move horizontally, thus adjusting the soil around the seedling roots during lifting. Patent CN118901536A uses four inclined digging claws arranged in an approximately conical structure, allowing the excavated soil and seedling to be transferred together during digging. However, this structure is complex, increasing maintenance difficulty and requiring multiple steps.

[0004] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0005] The main purpose of this utility model is to propose a cutting propagation device that is simple in structure, easy to operate, and integrates digging and transplanting.

[0006] Therefore, this utility model proposes a cutting propagation and burial device.

[0007] Preferably, the present invention may also have the following technical features:

[0008] A cutting propagation and burial device includes a fixing ring, digging claws, and a connecting rod. The fixing ring has 3-4 guide holes that extend through its upper and lower sides and are arranged at an angle. The lower end of each guide hole is close to the center of the fixing ring, while the upper end is away from the center of the fixing ring. Each guide hole is equipped with a digging claw, which slides in conjunction with the guide hole. The digging claw includes a shovel, a handle, and a connecting part. The two ends of the handle are respectively connected to the shovel and the connecting part. The connecting rod is used to connect the connecting parts of adjacent digging claws, so that the digging claws are connected as a whole.

[0009] Furthermore, the connecting part is a bent pipe structure; a connecting rod is provided inside the connecting part, and the connecting rod is slidably assembled in the cavity of the bent pipe.

[0010] Furthermore, it is equipped with 4 digging claws, and 4 guide holes are opened on the fixing ring accordingly.

[0011] Furthermore, the shovel handle and the digging blade are detachably connected and fixed, and the connecting part is welded and fixed.

[0012] Furthermore, the shovel handle and the digging blade are welded together.

[0013] Furthermore, when each excavator moves to its designated position, the four connecting parts are in a concentric circle.

[0014] Furthermore, when the four connecting parts are in a concentric circle, each digging blade has a spacing.

[0015] Furthermore, it also includes a limiting rod, with ring buckles at both ends of the limiting rod. One end of the limiting rod is fitted onto the fixed ring through the ring buckle. When the four connecting parts are in a concentric circle, the ring buckles at both ends of the limiting rod connect the connecting part and the fixed ring respectively.

[0016] Furthermore, the inner side of the ring is provided with a rubber layer.

[0017] Furthermore, each guide hole is evenly distributed on the fixing ring.

[0018] The beneficial effects of this utility model compared with the prior art include: after the shovels are assembled into the fixing ring, since the four shovels are inclined and can move independently along the axial direction of the guide hole, when the four shovels move to the predetermined position, the four connecting parts are in a concentric circle; at this time, the connecting rod extends from one side of the connecting part and inserts into an adjacent shovel connecting part, and the connecting rods of the other shovels are operated in the same way, so that the four connecting rods connect the four shovels into one unit. The whole device has a simple structure, is easy to operate, and is easy to manufacture. Attached Figure Description

[0022] Figure 4 This is another embodiment of the present invention. Detailed Implementation

[0023] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0024] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0025] like Figures 1-4 The illustrated cutting and burying device includes a fixing ring 1, digging claws, and a connecting rod 4. The fixing ring 1 has 3-4 guide holes 11 extending through its upper and lower sides and arranged at an angle. The lower end of each guide hole 11 is close to the center of the fixing ring 1, while the upper end is away from the center of the fixing ring 1. Each guide hole 11 is evenly distributed on the fixing ring 1, and each guide hole 1 is equipped with a digging claw. The digging claw and the guide hole 11 are slidably engaged, and the digging claw includes a shovel 23, a shovel handle 21, and a connecting part 22. The two ends of the shovel handle 21 are respectively connected to the shovel 23 and the connecting part 22. The connecting part 22 is a bent tube structure. A connecting rod 4 is provided inside the connecting part 22, and the connecting rod 4 is slidably assembled in the cavity of the bent tube to connect adjacent connecting parts 22, so that each digging claw is connected as a whole. For example, this embodiment uses 4 digging claws, corresponding to 4 guide holes 11 opened on the fixing ring 1. In the optional connection method for the digging claws, the shovel handle 21 and the digging blade 23 can be detachably connected and fixed (e.g., snap-fit, threaded connection) and welded to the connecting part 22. Alternatively, the shovel handle 21 can be assembled to the guide ring 1, and then the shovel handle 21 and the digging blade 23 can be welded to each other. After the digging blade 23 is assembled to the fixing ring 1, since the four digging claws are inclined and can move independently along the axial direction of the guide hole 11, when the four digging blades 23 move to the predetermined position, the four connecting parts 22 are in a concentric circle 5. At this time, the connecting rod 4 extends from one side of the connecting part 22 and is inserted into one adjacent digging claw connecting part 22. The connecting rods 4 of the other digging claws are operated in the same way, so that the four connecting rods 4 connect the four digging claws into one unit. Furthermore, the radius of the concentric circle 5 is determined by the digging claw connecting part 22, thereby adjusting the spacing between each digging blade 23 when the four connecting parts 22 are in a concentric circle 5.

[0026] In other words, during use, in order to facilitate the operation of the four digging shovels 23, the four digging claws are connected as one unit by the connecting rod 4, and the digging shovels are now inserted at an angle below the seedling; then the digging shovels are rotated to cut the soil around the seedling, the burying device is lifted, and the seedling is moved along with the soil; during the movement, the relative positions of the digging claw connecting part 22 and the fixing ring 1 are maintained to prevent the digging claws from loosening.

[0027] In a preferred embodiment, a limiting rod 3 is further included. Each end of the limiting rod 3 has a ring buckle. One end of the limiting rod 3 is fitted onto the fixing ring 1 via the ring buckle. When the four connecting parts 22 are in a concentric circle 5, the position of the limiting rod 3 is moved, and the angle of the limiting rod 3 is adjusted so that the ring buckle at the other end of the limiting rod 3 connects to the connecting part 22, specifically, the ring buckle is directly fitted onto the connecting part 22. Preferably, the inner side of the ring buckle has a rubber layer to increase friction. Sufficient limiting rods 3 are provided so that each connecting part 22 of the digging claw can be connected to one limiting rod 3. The limiting rods 3 fix the relative position of the connecting part 22 and the fixing ring 1, thereby preventing the digging claw from loosening and slipping during the transplanting of seedlings with soil.

[0028] Those skilled in the art will recognize that numerous variations are possible with respect to the above description, and the embodiments and figures are merely for describing one or more specific implementations.

[0029] Although exemplary embodiments of the present invention have been described and illustrated, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Furthermore, many modifications can be made to adapt specific situations to the doctrine of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but may include all embodiments and equivalents that fall within the scope of the present invention.
