[0001] This application relates to the field of forestry seedling technology, and in particular to a forestry seedling transplanting device. Background Technology

[0002] In the process of forestry planting, transplanting seedlings is a key step in optimizing the growth environment and improving growth quality. Larger seedlings often require thinning transplanting using specialized large-scale machinery due to their growing space requirements.

[0003] Publication (Announcement) No.: CN116267492B provides a forestry seedling transplanting device. This device includes a connecting frame, inside which a pressure platform is vertically mounted. Clamping arms a and b are hinged to the inner walls of the pressure platform. An adjusting push rod is hinged between the pressure platform and the opposing surfaces of clamping arms a and b. A semi-arc seat is fixedly mounted on the surface of clamping arm a, and a rotating arc frame is slidably connected to the inner wall of the semi-arc seat. A driven gear ring is fixedly mounted on the circumferential side of the rotating arc frame. The beneficial effects of this invention are: by setting up transplanting mechanisms a and b, this device can efficiently complete the transplanting of forestry seedlings. Furthermore, during seedling operations, this device can simultaneously remove the seedlings and open the transplanting holes through a morphological transformation. Through the realization of the above dual functions and dual working modes, the automation level, functionality, and practicality of this device are effectively improved.

[0004] In existing technologies, the connection between soil particles on the inner wall of the hole is easily severed when taking seedlings, which can easily lead to the loosening of aggregates, collapse of holes, and leakage of water and fertilizer. In addition, the root system is easily damaged when taking seedlings, resulting in a short-term decrease in the ability to absorb water and fertilizer. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the easy severing of soil particle connections on the inner wall of the hole during seedling removal, which easily leads to loose aggregates, hole collapse, water and fertilizer leakage, and easy damage to the root system during seedling removal, resulting in a short-term decrease in water and fertilizer absorption capacity.

[0007] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution involves starting multiple motors (2), whose output shafts drive multiple rotating columns (1), which in turn drive multiple gears (1), which in turn drive multiple arc-shaped racks to move downwards, and consequently, multiple outer casings and multiple cutters to move downwards, thus excavating the saplings. 2. This solution starts the motor three at the bottom of the cavity one. The output shaft of the motor three drives the sealing plate in the water outlet pipe at the bottom of the cavity one to rotate, so that the repair fluid can be transmitted to the nozzle facing the external soil through the diversion pipe one. Then, the sealing plate drives the rotating column five to rotate, and through linkage, it can push the connecting block to move downward. This allows multiple connecting rods to drive multiple protective plates to move upward to open. Since the protective plates move upward, they can block some of the soil. 3. This solution uses an upward-moving connecting block to compress a spring plate. The spring plate then moves the sealing strip upward, which in turn moves the rack upward. Through this linkage, the screw rotates, allowing a U-shaped push plate to push the gear four outward. This movement, along with the push plate, sleeve, pipe, nozzle, gear four, hydraulic cylinder four, and rack three, moves outward, positioning the nozzle's tip externally. Activating the nozzle then sprays the repair fluid. 4. This solution activates hydraulic cylinder four, whose output drives the top rack three to move up and down repeatedly. The top rack three, through the transmission rods that connect multiple rack threes, can simultaneously and continuously move up and down repeatedly, causing the sleeve to rotate the pipe and the nozzle to rotate, thus enabling the nozzle to spray over a wide area. 5. This solution involves starting the motor three at the bottom of cavity two and opening the sealing plate inside the water outlet pipe at the bottom of cavity two. By repeating the above steps, multiple protective plates inside the outer shell can be opened, and then nutrient solution can be sprayed onto the roots of the seedlings. This can specifically stimulate the sprouting of new roots, help damaged roots recover their absorption function as soon as possible, and directly improve the survival rate of transplanted seedlings.

[0008] This invention involves spraying a bio-aggregant onto the walls of the holes after seedling collection to quickly bind loose soil, reconstruct stable aggregates, prevent soil loss, and maintain a good soil environment. During planting, a nutrient solution is sprayed onto the roots to stimulate the growth of new roots, help damaged roots restore their ability to absorb nutrients, and improve the survival rate of transplanted seedlings.

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0012] Example 1 Reference Figures 1-16 A forestry seedling transplanting device includes: a body 1 and a track 2 disposed at the bottom of the body 1; a mechanical arm 3 is disposed on the front side of the body 1; two hydraulic cylinder supports 4 are disposed on the bottom front side of the body 1, the two hydraulic cylinder supports 4 are respectively located on the left and right sides of the mechanical arm 3; two hydraulic cylinders 5 are rotatably mounted between the two hydraulic cylinder supports 4 and the mechanical arm 3; a mechanical arm 7 is rotatably connected to the front end of the mechanical arm 3; a hydraulic cylinder 6 is rotatably mounted between the mechanical arm 3 and the mechanical arm 7 for driving the mechanical arm 7 to adjust its angle; a hydraulic cylinder support 2 is connected to the top of the mechanical arm 7; a hydraulic cylinder 3 8 is rotatably mounted on the hydraulic cylinder support 2; a connecting piece 10 is fixedly connected to the output end of the hydraulic cylinder 3 8; and the device also includes: A ring-shaped bracket 9 is positioned at the front of the connector 10. Two ring-shaped brackets 11 are rotatably connected to both sides of the ring-shaped bracket 9. A rotating rod is fixedly connected to the rear end of each of the two ring-shaped brackets 11. Motors 1 are installed at both ends of the bottom of the ring-shaped bracket 9, and the output shafts of the two motors 1 are fixedly connected to the two rotating rods respectively. The ring-shaped bracket 9 is not fixedly connected to the two ring-shaped brackets 11. By activating the two motors 1, the two ring-shaped brackets 11 can be driven to rotate relative to the ring-shaped bracket 9, forming an annular opening for accommodating the sapling. Subsequently, the device moves, positioning the sapling between the brackets 19 and... Between the two supports 11; then, the two motors 1 are started in reverse to close the opening for the next digging work; during the digging process, the two ring supports 11 can fit tightly against the soil around the roots of the seedling, ensuring that the roots of the seedling are not excessively damaged during digging; the ring supports 9 and 11 are both arc-shaped, which can better adapt to the shape of the seedling and can evenly wrap the root area of ​​the seedling when rotating and closing relative to each other; at the same time, its arc-shaped structure can also reduce friction with the surrounding environment during the movement of the device and improve the stability of the device operation.

[0013] Multiple fixing brackets 12 are respectively installed on the outside of the first ring bracket 9 and the two second ring brackets 11; The excavation mechanism, located inside the fixed frame 12, is used to excavate the saplings; The soil remediation mechanism, mounted on the fixed frame 12, is used to remediate the excavated soil and improve the survival rate of seedlings during planting. A protective mechanism, installed on the excavation mechanism, is used to protect the nozzle 32; Auxiliary mechanisms are installed on the soil remediation mechanism to assist in its operation. The spraying mechanism, installed on the soil remediation unit, is used for spraying remediation solution and nutrient solution over a large area.

[0014] Reference Figures 1-3 The excavation mechanism includes two sliding grooves 13 located on both sides inside the fixed frame 12. A slider 14 is slidably connected within both grooves 13. A housing 15 is fixedly connected to the bottom of the slider 14, and a cutter 16 is fixedly connected to the bottom of the housing 15. The housing 15 is inverted conical in shape, which helps to cut into the soil more smoothly when moving downwards, reducing resistance. The cutter 16 is an arc-shaped blade with sharp edges and a certain curvature, which can better conform to the soil around the seedling roots for cutting. During excavation, it can more efficiently separate the seedling roots from the surrounding soil while reducing damage to the seedling root system. An arc-shaped rack 20 is fixedly connected to the left and right ends of the rear side of the slider 14. The two arc-shaped racks 20 are arranged in parallel and both mesh with gear 19, ensuring balanced force when the slider 14 moves up and down, preventing tilting. A second motor 17 is located inside the right end of the fixed frame 12. A rotating column 18 is fixedly connected to the output shaft of the second motor 17. The rotating column 18 is connected to the fixed frame 1. 2. Rotary connection: Rotating column 18 is fixedly connected to two gears 19. By starting multiple motors 17, the output shafts of the multiple motors 17 drive the multiple rotating columns 18 to rotate, which in turn drive the multiple gears 19 to rotate. The rotation of the gears 19 drives the multiple arc-shaped racks 20 to move downwards, and also drives the multiple outer shells 15 and multiple cutters 16 to move downwards to dig the seedlings. During the downward movement of the multiple outer shells 15, their inverted conical structure continues to play an advantage, not only making the cutting action into the soil smoother, but also gradually squeezing the surrounding soil outwards as the depth increases, forming a relatively regular space that is conducive to the removal of the seedlings. When the multiple arc-shaped blades of the cutter 16 move downwards, they closely fit the soil around the roots of the seedlings, and with precise cutting action, completely separate the roots of the seedlings from the surrounding soil, ensuring that the damage to the root system of the seedlings is minimized during the digging process, providing a strong guarantee for the subsequent transplanting and survival of the seedlings.

[0015] Reference Figure 2 and Figures 4-8The soil remediation mechanism includes a box 21 located inside the front of the fixing frame 12.

Both cavity 1 (23) and cavity 2 (24) are fixedly connected to outlet pipes (36), and each outlet pipe (36) is rotatably connected to a sealing plate (25).

Hose 2 is fixedly connected to multiple nozzles 32 located at the rear, and hose 1 is fixedly connected to multiple nozzles 32 located at the front. This allows the multiple nozzles 32 located at the rear to spray the repair solution from the nozzles 32 using their own micro-pumps, ensuring even application to the roots of the seedlings. Nutrient solution is sprayed evenly. Multiple nozzles 32 located on the front side can spray repair solution onto the soil on the outside.

Connecting blocks 35 are fixedly connected to the bottom of the front protective plate 33 and the multiple rear protective plates 33 on their adjacent sides. Two connecting rods 34 are fixedly connected between the multiple connecting blocks 35. A rack 37 is fixedly installed on the top of the adjacent sides of the two connecting rods 34. The rack 37 is meshed with a gear 38. A rotating column 39 is fixedly connected to the gear 38. The multiple rotating columns 39 are rotatably connected to the grooves 52 and 51 respectively.

[0017] Reference Figures 7-9 , Figure 11 , Figure 12 , Figure 14 and Figure 15The auxiliary mechanism includes multiple spring plates 53 respectively disposed on the top of multiple grooves 51 and multiple grooves 52. A sealing strip 54 is fixedly connected to the side of each spring plate 53 near the middle of the outer casing 15. A rack 55 is fixedly connected to the top of the sealing strip 54.

The outer surfaces of multiple screws 59 are fixedly connected to bevel gears 61. Bevel gears 61 mesh with bevel gears 62. The front end of bevel gears 62 is fixedly connected to a rotating column 63. The rotating column 63 is rotatably connected to the outer shell 15. The outer surface of the rotating column 63 is fixedly connected to a sprocket 64. The sprocket 64 and the sprocket 58 are meshed with the same chain 65. The spring plate 53 is made of elastic steel sheet. When the connecting block 35 moves down, it squeezes the spring plate 53 to deform. When the protective plate 33 closes, the spring plate 53 resets and pushes the connecting block 35 to move up, so as to realize the automatic closing of the protective plate 33.

[0018] Reference Figure 7 and Figure 8 The spraying mechanism includes two hydraulic cylinders 66, which are located on the top of the two push plates 29 on opposite sides. Gears 68 are fixedly connected to the outer surfaces of multiple sleeves 30, and racks 67 are meshed with multiple gears 68. A transmission rod is connected between multiple racks 67 to ensure that when the top rack 67 moves, all racks 67 move synchronously through the transmission rod. The output ends of the two hydraulic cylinders 66 are fixedly connected to the two top racks 67 respectively.

[0019] The implementation principle of a forestry seedling transplanting device in this application embodiment is as follows: When in use, multiple motors 17 are started, and the output shafts of the multiple motors 17 drive multiple rotating columns 18 to rotate. The multiple rotating columns 18 drive multiple gears 19 to rotate. The rotation of the multiple gears 19 can drive multiple arc-shaped racks 20 to move downward, and drive multiple outer shells 15 and multiple cutters 16 to move downward to dig the seedling. After successfully cutting the seedling from the surrounding soil, the motor 26 at the bottom of the cavity 23 is started. The output shaft of the motor 26 drives the sealing plate 25 in the water outlet pipe 36 at the bottom of the cavity 23 to rotate, so that the repair liquid can be transmitted to the nozzle 32 facing the external soil through the diversion pipe 27. The sealing plate 25 drives the rotating column 45 to rotate, which in turn drives the bevel gear 46 to rotate, which in turn drives the bevel gear 47 to rotate, which in turn drives the rotating column 48 to rotate, which in turn drives the universal joint 49 to rotate, which in turn drives the rotating column 50 to rotate, which in turn drives the rotating column 44 to rotate, which in turn drives the universal joint 43 to rotate, which in turn drives the rotating column 42 to rotate, which in turn drives the bevel gear 41 to rotate, which in turn drives the bevel gear 40 to rotate, which in turn drives the rotating column 39 to rotate, which in turn drives the gear 38 to rotate, which in turn drives the rack 37 to move upward. This pushes the connecting block 35 to move downward, which in turn drives the multiple protective plates 33 to move upward through the multiple connecting rods 34 to open the door. Since the protective plates 33 move upward, they can block some of the soil. The connecting block 35 moves upward to compress the spring plate 53. The spring plate 53 drives the sealing strip 54 to move upward. The sealing strip 54 drives the rack 2 55 to move upward. The rack 2 55 drives the gear 3 56 to rotate. The gear 3 56 drives the rotating column 1 57 to rotate. The rotating column 1 57 drives the sprocket 1 58 to rotate. The sprocket 1 58 drives the sprocket 2 64 to rotate via the chain 65. This causes the rotating column 2 63 to drive the bevel gear 62 to rotate. The bevel gear 62 drives the bevel gear 5 61 to rotate. The bevel gear 5 61 drives the screw 59 to rotate. The rotation of the screw 59... The U-shaped push plate 60 can be used to push the gear 4 68 outward, which in turn pushes the push plate 29, sleeve 30, pipe 31, nozzle 32, gear 4 68, hydraulic cylinder 4 66, and rack 3 67 outward, so that the front end of the nozzle 32 is on the outside. Then, the nozzle 32 can be started to spray the repair fluid. At the same time, the hydraulic cylinder 4 66 is started. The output end of the hydraulic cylinder 4 66 drives the rack 3 67 at the top to move up and down reciprocally. The rack 3 67 at the top can drive multiple racks 3 67 through the transmission rods that are connected between them. 7. Simultaneously, the sleeve 30 moves up and down repeatedly, causing the pipe 31 to rotate and the nozzle 32 to rotate. This allows the nozzle 32 to spray over a wide area, ensuring the bio-aggregate is sprayed onto the wall surface. This quickly binds loose soil particles, allowing the inner wall of the hole to reform a stable aggregate structure, preventing soil erosion. Beneficial microbial agents, such as Bacillus subtilis, need to attach to a "structured soil surface" to survive and reproduce—when sprayed onto the inner wall of the hole, the agent will directly adhere to the cut soil cracks, rather than being washed away by water flow. Buried in deep, anaerobic soil, the holes will naturally collapse and merge with the surrounding soil, allowing the microbial agent to gradually spread to the surrounding soil and improve the microbial environment of the entire area. This lays the foundation for "future use of the holes": if replanting is needed in the area later, such as when some seedlings fail to be transplanted, the inner wall of the repaired annular holes can maintain soil fertility and aeration, and the roots of the new seedlings will come into contact with "repaired healthy soil," resulting in a higher survival rate. Even if no replanting is needed, the repaired holes can be quickly penetrated by the roots of the surrounding vegetation, preventing the formation of soil cavities. After excavation is completed, the sapling can be removed by the excavation mechanism using hydraulic cylinders 5, 6, and 8. When planting is needed, first place the sapling into the planting hole, then start the motor 26 at the bottom of cavity 24 and open the sealing plate 25 inside the water outlet pipe 36 at the bottom of cavity 24. Repeat the above steps to open the multiple protective plates 33 inside the outer shell 15, and then spray nutrient solution on the roots of the sapling. This can specifically stimulate the sprouting of new roots, help the damaged root system to recover its absorption function as soon as possible, and directly improve the survival rate of transplanted saplings.

[0020] Example 2 The difference between this embodiment and Embodiment 1 is that an airbag 69 is fixedly installed on the bottom side inside the fixed frame 12. The front side of the airbag 69 has an outlet and an inlet. The outlet is connected to a one-way valve 70 through a pipe and is fixedly connected to a diversion pipe 72. The inlet is connected to a one-way valve 71 through a pipe and is connected to an external air source. Multiple hoses 3 are connected to the outer surface of the diversion pipe 72. The ends of the multiple hoses 3 extend to the openings of multiple grooves 51 and 52. When the arc-shaped rack 20 moves downward, it will squeeze the airbag 69, so that the air in the airbag 69 enters the grooves 51 and 52 through the one-way valve 70 and the diversion pipe 72. Air can be sprayed when the protective plate 33 is opened to prevent dirt from entering the grooves 51 or 52.

[0021] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
