Description

Technical Field

[0001] This invention belongs to the field of forestry seedling technology, specifically a forestry seedling cutting propagation device. Background Technology

[0002] Forestry seedling cultivation is an important part of forestry production. It involves cultivating and propagating high-quality tree seedlings through artificial control, management and optimization of environmental conditions.

The gear is slidably installed inside the receiving chamber. A rack plate is provided below the gear. The rack plate is fixedly installed on the inner wall of the receiving chamber.

[0009] As a further technical solution of the present invention, the plurality of cutting plates are combined into a conical shape.

[0010] As a further technical solution of the present invention, the inner wall of the accommodating chamber is provided with bristles, which are uniformly arranged in a ring array.

[0011] As a further technical solution of the present invention, a first spring is fixedly installed at one end of the brush bristles, and the end of the first spring away from the brush bristles is fixedly installed on the inner wall of the accommodating chamber.

[0012] As a further technical solution of the present invention, the positioning component includes a positioning rod disposed on one side of the main body of the device. A limiting ring is fixedly installed on the outer wall of the positioning rod. A movable plate is installed on the outer wall of the limiting ring. A fixed plate is installed on the outer wall of the movable plate. The fixed plate is fixedly installed on the outer wall of the feeding cylinder. An adjusting plate is installed on the outer wall of the positioning rod. The adjusting plate is slidably installed inside the main body of the device through an adjusting component.

[0013] As a further technical solution of the present invention, the limiting ring is rotatably installed on the inner wall of the moving plate.

[0014] As a further technical solution of the present invention, the adjustment component includes a connecting plate disposed inside the adjustment plate, a second spring is installed at the bottom end of the connecting plate, a limit block and a pressing rod are fixedly connected to the top end of the connecting plate, the limit block is embedded in the inner wall of the limit hole, and the limit hole is opened inside the main body of the device and is evenly distributed.

[0015] As a further technical solution of the present invention, the movable plate is slidably connected to the fixed plate.

[0016] As a further technical solution of the present invention, the outer wall of the positioning rod is provided with a spiral groove, and the inner wall of the spiral groove is slidably connected with a guide rod, which is fixedly installed on the inner wall of the adjusting plate.

[0017] As a further technical solution of the present invention, the positioning rod is slidably connected to the adjusting plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention, through the setting of the cutting propagation component, allows for the following steps when cutting propagation is required in forestry seedling cultivation: First, the main body of the device is moved to the cutting location. Then, the seedling is placed into the feeding cylinder, and the motor is started. When the motor starts, it drives the first threaded rod to rotate. The rotation of the first threaded rod drives the ear plate to move downwards. The downward movement of the ear plate drives the feeding cylinder to move downwards. The downward movement of the feeding cylinder drives the expansion plate and the cutting plate to move downwards, so that the cutting plate is embedded into the soil. Simultaneously, the downward movement of the expansion plate drives the gear to accommodate... The device moves downwards inside the chamber. When the gear meshes with the rack plate, it rotates. The rotation of the gear drives the rotation of the second threaded rod, which in turn drives the slider to move. The slider's movement causes the expansion plate and the cutting plate to move outwards, opening up the soil and forming planting pits. Seedlings inside the feeding cylinder fall into the planting pits for cutting. This device eliminates the need to dig planting pits in advance, simplifying the cutting process and improving the efficiency of the cutting operation.

[0020] 2. This invention, through the setting of the positioning component, allows the feeding cylinder to move downwards during cutting propagation, causing the fixed plate to move downwards. The movement of the fixed plate then causes the movement of the moving plate, which in turn causes the positioning rod to move, embedding the positioning rod into the soil in front of the main body of the device for marking. This helps workers know the next cutting location and perform equidistant cutting operations, ensuring that each seedling receives the same growth conditions and management level, thereby achieving higher production efficiency.

[0021] 3. This invention, through the setting of the adjustment components, allows for adjustment of the spacing between cutting points. Pressing the pressing rod downwards causes the connecting plate to move, which in turn moves the limiting block, causing it to slide out of the inner wall of the limiting hole. Then, the adjusting plate is moved, sliding within the main body of the device. This movement of the adjusting plate causes the positioning rod to move closer to or further away from the main body of the device. After adjustment, the pressing rod is released, and the elastic potential energy is released by the second spring, causing the connecting plate to move upwards and reset. This allows the limiting block to be embedded and fixed within the limiting hole, thus adjusting the spacing between cutting points to adapt to different types of plants or different climatic conditions, improving the adaptability of the device.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown in the embodiment of the present invention, a forestry seedling cutting propagation device includes a device body 1, with cylinders 2 installed at the four corners of the bottom of the device body 1. The output end of the cylinders 2 is fixedly connected to the bottom of the device body 1. A caster wheel 3 is installed at the bottom of the cylinders 2. A cutting propagation component is provided inside the device body 1. A positioning component is provided on one side of the device body 1. A handrail 4 is fixedly installed on the other side of the device body 1.

[0032] The cutting assembly includes a feeding cylinder 6 installed inside the main body 1 of the device. Both sides of the top of the feeding cylinder 6 are fixedly connected to ear plates 7. One of the ear plates 7 is internally threaded with a first threaded rod 8. A motor 9 is installed at the bottom of the first threaded rod 8. The motor 9 is located inside the main body 1 of the device. An expansion plate 10 is slidably installed at the bottom of the feeding cylinder 6 through an expansion assembly. The expansion plates 10 are evenly arranged in a ring array. A cutting plate 11 is fixedly connected to the bottom of each expansion plate 10. A receiving chamber 12 is provided on the outside of the cutting plate 11. The receiving chamber 12 is fixedly installed at the bottom of the main body 1 of the device.

[0033] The expansion assembly includes a slider 26 fixedly installed on the top of the expansion plate 10. The slider 26 is slidably installed inside the feeding cylinder 6. A second threaded rod 27 is threadedly connected inside the slider 26. A gear 28 is fixedly installed at one end of the second threaded rod 27. The gear 28 is slidably installed inside the accommodating chamber 12. A rack plate 29 is provided below the gear 28. The rack plate 29 is fixedly installed on the inner wall of the accommodating chamber 12.

[0034] The existing patent CN220369094U discloses a cutting propagation device for fruit tree seedlings. This patent discloses a table 1, a cylinder 2, casters 3 and a handrail 4. The main body 1, cylinder 2, casters 3 and handrail 4 of the device in this application all adopt the same technical means as the prior art. These technical means will not be described in detail here.

[0035] When cutting propagation is required in forestry seedling cultivation, the main body 1 of the device is first moved to the cutting location. Then, the seedlings are placed into the feeding cylinder 6, and the motor 9 is started. When the motor 9 starts, it drives the first threaded rod 8 to rotate. When the first threaded rod 8 rotates, it drives the ear plate 7 to move downward. The downward movement of the ear plate 7 drives the feeding cylinder 6 to move downward. The downward movement of the feeding cylinder 6 drives the expansion plate 10 and the cutting plate 11 to move downward, so that the cutting plate 11 is embedded into the soil. At the same time, the downward movement of the expansion plate 10 drives the gear 28 to move downward inside the receiving chamber 12. When the gear 28 moves and meshes with the rack plate 29, it rotates. The rotation of the gear 28 drives the rotation of the second threaded rod 27, which in turn drives the slider 26 to move. The movement of the slider 26 drives the expansion plate 10 and the cutting plate 11 to move, causing the multiple expansion plates 10 and cutting plates 11 to move outward and open, breaking up the soil to form a planting pit. The seedlings inside the feeding cylinder 6 fall into the planting pit for cutting. This device eliminates the need to dig planting pits in advance, simplifies the cutting process, and thus improves the efficiency of cutting.

[0036] like Figure 3 As shown, multiple cutting plates 11 are combined into a cone shape.

[0037] The conical base is sharp and easily penetrates the soil layer. During insertion, it can gradually disperse soil pressure and reduce soil cracking or collapse caused by excessive local pressure.

[0038] like Figure 3 As shown, the inner wall of the accommodating chamber 12 is provided with bristles 13, which are evenly arranged in a ring array.

[0039] After the cutting is inserted, the first threaded rod 8 is reversed by controlling the motor 9. Similarly, the cutting plate 11 is moved upward and slid into the interior of the receiving chamber 12. The outer wall of the cutting plate 11 contacts the end of the bristles 13. The bristles 13 clean the soil on the outer wall of the cutting plate 11 to prevent soil from adhering to the outer wall of the cutting plate 11 and affecting the resistance of subsequent operations.

[0040] like Figure 4 As shown, a first spring 14 is fixedly installed at one end of the brush bristles 13, and the end of the first spring 14 away from the brush bristles 13 is fixedly installed on the inner wall of the accommodating chamber 12.

[0041] The bristles 13 have a certain degree of elasticity, which can generate a certain amount of friction and impact when they come into contact with the cutting plate 11, which helps to remove dirt, stones and other impurities attached to the outer wall of the cutting plate 11, resulting in a better cleaning effect.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the positioning assembly includes a positioning rod 17 disposed on one side of the main body 1 of the device. A limit ring 5 is fixedly installed on the outer wall of the positioning rod 17. A movable plate 16 is installed on the outer wall of the limit ring 5. A fixed plate 15 is installed on the outer wall of the movable plate 16. The fixed plate 15 is fixedly installed on the outer wall of the feeding cylinder 6. An adjusting plate 18 is installed on the outer wall of the positioning rod 17. The adjusting plate 18 is slidably installed inside the main body 1 of the device through the adjusting assembly.

[0043] During the cutting operation, the feeding cylinder 6 moves downward, causing the fixed plate 15 to move downward. The movement of the fixed plate 15 causes the moving plate 16 to move, and the movement of the moving plate 16 causes the positioning rod 17 to move, so that the positioning rod 17 is embedded in the soil in front of the main body 1 of the device for marking. This makes it easier for the staff to know the next cutting location and carry out equidistant cutting operations, ensuring that each seedling receives the same growth conditions and management level, thereby achieving higher production efficiency.

[0044] like Figure 5 As shown, the limiting ring 5 is rotatably mounted on the inner wall of the movable plate 16.

[0045] like Figures 1 to 6 As shown, the adjustment assembly includes a connecting plate 20 disposed inside the adjustment plate 18. A second spring 22 is installed at the bottom end of the connecting plate 20. A limit block 19 and a pressing rod 21 are fixedly connected to the top end of the connecting plate 20. The limit block 19 is embedded in the inner wall of the limit hole 23. The limit hole 23 is opened inside the main body 1 of the device and is evenly distributed.

[0046] When it is necessary to adjust the spacing between the cutting points, press down the pressing rod 21. The movement of the pressing rod 21 drives the movement of the connecting plate 20, which in turn drives the movement of the limiting block 19, causing the limiting block 19 to slide out from the inner wall of the limiting hole 23. Then, move the adjusting plate 18 so that it slides inside the main body 1 of the device. The movement of the adjusting plate 18 drives the movement of the positioning rod 17, causing the positioning rod 17 to move closer to or further away from the main body 1 of the device. After adjustment, release the pressing rod 21, and the elastic potential energy released by the second spring 22 causes the connecting plate 20 to move upward and reset, thereby fixing the limiting block 19 into the limiting hole 23. This allows for adjustment of the spacing between the cutting points, adapting to different types of plants or different climatic conditions for cutting operations, and improving the adaptability of the device.

[0047] like Figure 2 As shown, the movable plate 16 is slidably connected to the fixed plate 15.

[0048] Even after the position is adjusted, the positioning rod 17 can still move up and down through the fixed plate 15, thereby driving the moving plate 16 to move up and down.

[0049] like Figure 5 and Figure 6 As shown, the outer wall of the positioning rod 17 is provided with a spiral groove 24, and the inner wall of the spiral groove 24 is slidably connected with a guide rod 25, which is fixedly installed on the inner wall of the adjusting plate 18.

[0050] During the cutting operation, the positioning rod 17 moves downward, causing the spiral groove 24 to slide on the outer wall of the guide rod 25, which forces the positioning rod 17 to rotate, making it easier for the positioning rod 17 to be embedded into the soil for positioning.

[0051] like Figure 5 and Figure 6 As shown, the positioning rod 17 is slidably connected to the adjusting plate 18.

[0052] Working principle and usage process:

[0053] When cutting propagation is required in forestry seedling cultivation, first move the main body 1 of the device to the cutting location. Then, according to the distance between the positioning rod 17 and the main body 1 of the device, press down the pressing rod 21. The movement of the pressing rod 21 drives the movement of the connecting plate 20. The movement of the connecting plate 20 drives the movement of the limiting block 19, causing the limiting block 19 to slide out from the inner wall of the limiting hole 23. Then move the adjusting plate 18, causing the adjusting plate 18 to slide inside the main body 1 of the device. The movement of the adjusting plate 18 drives the movement of the positioning rod 17, causing the positioning rod 17 to move closer to or further away from the main body 1 of the device. After adjustment, release the pressing rod 21. The elastic potential energy is released by the second spring 22, causing the connecting plate 20 to move upward and reset, thereby embedding the limiting block 19 into the limiting hole 23 and fixing it, thus completing the adjustment.

[0054] Then, the seedlings are put into the feeding cylinder 6, and finally the motor 9 is started. When the motor 9 starts, it drives the first threaded rod 8 to rotate. When the first threaded rod 8 rotates, it drives the ear plate 7 to move downward. The ear plate 7 moves downward, which drives the feeding cylinder 6 to move downward. The feeding cylinder 6 moves downward, which drives the expansion plate 10 and the cutting plate 11 to move downward, so that the cutting plate 11 is embedded in the soil. At the same time, the expansion plate 10 moves downward, which drives the gear 28 to move downward in the accommodating chamber 12. When the gear 28 moves and meshes with the rack plate 29, it rotates. The rotation of the gear 28 drives the rotation of the second threaded rod 27. The rotation of the second threaded rod 27 drives the movement of the slider 26. The movement of the slider 26 drives the expansion plate 10 and the cutting plate 11 to move, so that the multiple expansion plates 10 and cutting plates 11 move outward and open, which opens up the soil and forms a planting pit. The seedlings inside the feeding cylinder 6 fall into the planting pit.

[0055] After the cutting is inserted, the first threaded rod 8 is reversed by controlling the motor 9. Similarly, the cutting plate 11 is moved upward and slid into the interior of the receiving chamber 12. The outer wall of the cutting plate 11 contacts the end of the bristles 13. The soil on the outer wall of the cutting plate 11 is cleaned by the bristles 13. The main body of the device is moved again to carry out continuous operation.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
