Description

Technical Field

[0001] The present invention relates to the technical field of fertilization, and more specifically, to a system and method for precise fertilization of seedlings and tree cultivation. Background Art

[0002] Precision fertilization refers to the use of advanced technologies and methods to accurately control the type, quantity, time and location of fertilization based on the specific needs of crops and the actual nutrient status of the soil, so as to improve fertilizer utilization, reduce fertilizer loss, optimize the crop growth environment, increase crop yield and quality, and reduce negative impacts on the environment.

[0003] In the prior art, in order to achieve precise fertilization for seedling and tree cultivation, a layered fertilization method is usually adopted, that is, fertilizers are applied to different depths of the soil. This method usually applies most of the base fertilizer to the deeper layers of the soil so that the crops can gradually absorb it during the growth process. At the same time, a small amount of quick-acting fertilizer is applied to the surface of the soil to meet the nutritional needs of the early growth of crops. Layered fertilization helps to improve the utilization rate of fertilizers and promote the development of crop roots.

[0004] Existing layered fertilization devices are often used in the growth and development of crops that are sensitive to fertilizers and have well-developed root systems. For example, a Chinese patent for a layered fertilization device suitable for sand ginger black soil (application number: CN202410562603.4) discloses a layered fertilization device, including a fertilization frame, a soil-breaking component, a fertilization component, and a soil-covering component. When performing layered fertilization, the soil layer is first excavated and turned over by the soil-breaking component, and then the fertilization component is used to accurately fertilize the turned soil layer. Finally, the soil covering component is used to cover the land where the fertilization has been completed, thereby completing the layered fertilization;

[0005] Although the existing technology can complete the layered fertilization of general agricultural crops, the layered and precise fertilization required for seedling and tree cultivation requires fertilization at a deeper depth. When the existing technology digs the deeper soil layer, it is easy to loosen the land in a large area, making it difficult to fully cover and compact the subsequent covering soil, resulting in fertilizer nutrient loss and affecting the growth of seedlings and trees. Summary of the invention

[0018] A method for using a precision fertilization system for seedling and tree cultivation, comprising the following steps:

[0019] Step 1: Move the fertilizer rack to the seedlings or trees that need to be fertilized, so that the fertilizer tube is aimed at the area that needs to be fertilized;

[0020] Step 2: Start the hydraulic press, so that the hydraulic press drives the fertilizer pipe to move downward, the fertilizer pipe drives the extrusion shell to move, the extrusion shell drives the extrusion disc to move, the extrusion disc drives the first slider to move, the first slider drives the connecting rod to rotate, so that the other end of the connecting rod drives the second slider to move, the second slider drives the driving rod to move, and the driving rod drives the supporting disc to move;

[0021] The third step: continue to start the hydraulic press, so that the fertilizer pipe continues to move, and the fertilizer pipe drives the drill tube to move, so as to drill the fertilizer hole through the drill tube;

[0022] Step 4: Start the hydraulic press in reverse, so that the hydraulic press drives the bottom end of the drill tube to move to the same level as the ground through the fertilizer pipe. At this time, the staff pulls the drive block to both sides, so that the drive block drives the connecting curved rod to move, and the connecting curved rod drives the drill tube to move away from the fertilizer pipe. At this time, the auxiliary groove abuts against the locking tooth block and pushes the locking tooth block to rotate, so that the locking tooth block moves to the inner wall of the locking groove when the drive block abuts against the fixed plate, thereby completing the positioning of the drill tube;

[0023] Step 5: Remove an accurate amount of fertilizer from the fertilizer storage box and discharge it into the fertilizer holes through the delivery pipe, working box and fertilizer pipe;

[0024] Step 6: The staff pushes the driving block, so that the driving block drives the drill tube to approach each other through the connecting curved rod, and the drill tube drives the first locking plate to move, and the first locking plate drives the locking round block to move, so that the locking round block abuts against one side of the locking arc block. At this time, the locking round block pushes the locking arc block to rotate to both sides, and the locking arc block squeezes the second spring, so that the second spring undergoes elastic deformation and accumulates elastic potential energy. When the locking round block moves to the inner side of the locking arc block, the second spring releases the elastic potential energy, undergoes elastic deformation, and pushes the locking arc block to abut against both sides of the locking round block, thereby completing the fixation of the drill tube;

[0025] Step 7: Continue to start the hydraulic press in reverse, so that the hydraulic press drives the covering plate to reset through the fertilizer pipe, extrusion shell, extrusion disc, first slider, second slider, connecting rod and driving rod, so that the soil around the fertilizer hole is gathered in the fertilizer hole during the reset of the covering plate. At this time, the staff starts the hydraulic press, so that the hydraulic press drives the drill barrel to move downward through the fertilizer pipe, and repeats this step until the fertilizer hole is filled and compacted, thereby completing the precise fertilization of seedlings or trees.

[0026] The beneficial effects of the present invention are:

[0027] The invention provides a seedling and tree cultivation precision fertilization system and method. By combining a drilling assembly with a fertilizer pipe, the invention can make the fertilizer pipe more accurate in fertilizing compared with the prior art, avoiding the problem that the fertilizer pipe is moved to the ground-breaking area after the ground is broken, and it is difficult to accurately move the fertilizer pipe to the top of the ground-breaking area, resulting in a decrease in fertilization effect and affecting the growth and cultivation of seedlings and trees. The fertilization accuracy of the fertilization mechanism is improved, thereby improving the growth and cultivation effect of seedlings and trees.

[0028] The present invention provides a soil covering component. Before fertilizing, the hydraulic press drives the support plate to extend through the fertilizer pipe, the extrusion shell, the extrusion disc, the first slider, the second slider, the connecting rod and the driving rod. When the fertilization hole needs to be covered with soil, the hydraulic press is started in reverse to drive the support plate to reset. Therefore, the support plate gathers the soil around the hole in the hole during the resetting process. This avoids the problem that when the prior art digs deeper soil layers, a large area of ​​the land is easily loosened, making it difficult to fully cover and compact the subsequent soil covering, resulting in fertilizer nutrient loss and affecting the growth of seedlings and trees. This reduces fertilizer nutrient loss, improves fertilizer utilization, and thus improves the growth effect of seedlings and trees. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods. Embodiment 1

[0039] like Figure 1-Figure 7 As shown, in the first embodiment, a precise fertilization system for seedling and tree cultivation is provided, including a fertilization frame 1 and a fertilization mechanism; the fertilization mechanism includes:

[0040] The driving assembly includes a driving wheel 2 and a fixing column 3 arranged at both ends of the fertilizer applying frame 1, which can be conveniently transported and fixed;

[0041] The feeding assembly includes a fertilizer storage box 4 arranged at the top of the fertilizer rack 1, a delivery pipe 5 is fixedly installed at one end of the fertilizer storage box 4, and the other end of the delivery pipe 5 is connected to a working box 6, which can discharge an accurate amount of fertilizer from the delivery pipe 5 through the fertilizer storage box 4 into the working box 6;

[0042] The drilling assembly includes a hydraulic press 7 arranged on one side of the working box 6 and a fertilizer pipe 8 inside the working box 6. The output end of the hydraulic press 7 is connected to the fertilizer pipe 8. The bottom end of the fertilizer pipe 8 passes through the fertilizer frame 1 and extends to the bottom of the fertilizer frame 1. The outer wall of the fertilizer pipe 8 is provided with a soil covering assembly for burying the holes, and the fertilizer pipe 8 can be driven by the hydraulic press 7 to drill holes. Compared with the prior art, by combining the drilling assembly with the fertilizer pipe 8, the fertilizer pipe 8 can be made more accurate when fertilizing, avoiding the problem of moving the fertilizer pipe 8 to the ground-breaking area after breaking the ground, and it is difficult to accurately move the fertilizer pipe 8 to the top of the ground-breaking area, resulting in a decrease in fertilization effect and affecting the growth and cultivation of seedlings and trees. The fertilization accuracy of the fertilization mechanism is improved, thereby improving the growth and cultivation effect of seedlings and trees.

[0043] See also Figure 2 , Figure 3 and Figure 6 As shown, the soil covering component includes an extrusion shell 9 arranged on the outer wall of the fertilizer pipe 8, an extrusion disc 10 is slidably installed on the bottom end of the extrusion shell 9, a first slider 11 is evenly fixedly installed on the bottom end of the extrusion disc 10, a second slider 12 is slidably installed on one side of the first slider 11, the first slider 11 and the second slider 12 are connected by two connecting rods 13, a driving rod 14 is fixedly installed on the bottom end of the second slider 12, a support disk 15 is slidably installed on the top end of the driving rod 14, a first locking component is arranged on the inner side of the support disk 15, a limiting plate 16 is fixedly installed on one side of the second slider 12, a soil covering plate 17 is fixedly installed on the bottom end of the driving rod 14, and a barrier component is arranged on the inner side of the soil covering plate 17; by arranging the soil covering component, before fertilization, The hydraulic press 7 drives the support plate 15 to extend through the fertilizer pipe 8, the extrusion shell 9, the extrusion disc 10, the first slider 11, the second slider 12, the connecting rod 13 and the driving rod 14, and when the fertilizer holes need to be covered with soil, the hydraulic press 7 is started in reverse, so that the hydraulic press 7 drives the support plate 15 to reset, so that the support plate 15 gathers the soil around the hole in the hole during the reset process, avoiding the problem that when the prior art digs deeper soil layers, it is easy to turn over the loose land in a large area, making it difficult to fully cover and compact the subsequent covering soil, resulting in the loss of fertilizer nutrients and affecting the growth of seedlings and trees. The nutrient loss of fertilizer is reduced, the utilization rate of fertilizer is improved, and the growth effect of seedlings and trees is improved.

[0044] See also Figure 3 and Figure 4As shown, the first locking assembly includes a limiting protrusion 18 arranged on the inner side of the support plate 15. The number of the limiting protrusions 18 is the same as the number of the first sliding blocks 11. The limiting protrusions 18 are all slidably installed in the slide grooves provided on the outer wall of the extrusion shell 9. The top ends of the limiting protrusions 18 abut against the limiting blocks 19, so that when the extrusion shell 9 moves, the extrusion shell 9 can drive the extrusion disc 10 to move through the limiting blocks 19. A rotating shaft 20 is fixedly installed on the inner wall of the limiting block 19, and one end of the driving wheel 2 of the rotating shaft 20 is rotatably installed on one side of the extrusion shell 9. A first spring 21 is installed on the bottom end of the limiting block 19 away from one end of the limiting protrusion 18.

[0045] See also Figure 3 to Figure 4 As shown, the top of the limit block 19 near the limit protrusion 18 is symmetrically installed with a rubber block 22, and the rubber block 22 is fixedly installed on the inner wall of the extrusion shell 9, which can further enhance the fixing effect of the extrusion disc 10 and avoid the problem that when the extrusion shell 9 moves at a faster speed, the thrust of the limit protrusion 18 on the limit block 19 easily exceeds the thrust of the first spring 21 on the limit block 19, causing the limit block 19 to rotate and stop abutting against the limit protrusion 18, so that the covering assembly cannot be fully deployed.

[0046] To summarize, by setting up the first locking assembly, the extrusion disc 10 can be driven to move through the limit block 19 and the limit protrusion 18 when the extrusion shell 9 moves, thereby driving the covering assembly to unfold, and after the covering assembly is unfolded, the limit protrusion 18 abuts against the limit block 19 and pushes the limit block 19 to rotate, so that the limit block 19 rotates to one side of the limit protrusion 18, so that the extrusion disc 10 stops abutting against the limit protrusion 18, thereby ending the locking effect of the first locking assembly.

[0047] A method for using a precision fertilization system for seedling and tree cultivation, comprising the following steps:

[0048] Step 1: Move the fertilizer rack 1 to the seedlings or trees that need to be fertilized, so that the fertilizer pipe 8 is aligned with the area that needs to be fertilized;

[0049] Step 2: Start the hydraulic press 7, so that the hydraulic press 7 drives the fertilizer pipe 8 to move downward, the fertilizer pipe 8 drives the extrusion shell 9 to move, the extrusion shell 9 drives the extrusion disc 10 to move, the extrusion disc 10 drives the first slider 11 to move, the first slider 11 drives the connecting rod 13 to rotate, so that the other end of the connecting rod 13 drives the second slider 12 to move, the second slider 12 drives the driving rod 14 to move, and the driving rod 14 drives the supporting disc 15 to move;

[0050] The third step: continue to start the hydraulic press 7, so that the fertilization tube 8 continues to move, and the fertilization tube 8 drives the drill tube 23 to move, so that the fertilization hole is excavated through the drill tube 23;

[0051] Step 4: Start the hydraulic press 7 in reverse, so that the hydraulic press 7 drives the bottom end of the drill tube 23 to move to the same level with the ground through the fertilizer pipe 8. At this time, the staff pulls the driving block 25 to both sides, so that the driving block 25 drives the connecting curved rod 24 to move, and the connecting curved rod 24 drives the drill tube 23 to move away from the fertilizer pipe 8. At this time, the auxiliary groove 31 abuts against the locking tooth block 29 and pushes the locking tooth block 29 to rotate, so that the locking tooth block 29 moves to the inner wall of the locking groove 30 when the driving block 25 abuts against the fixing plate 26, thereby completing the positioning of the drill tube 23.

[0052] Step 5: Remove an accurate amount of fertilizer from the fertilizer storage box 4 and discharge it into the fertilizer hole through the delivery pipe 5, the working box 6 and the fertilizer pipe 8;

[0053] Step 6: The staff pushes the driving block 25, so that the driving block 25 drives the drill tube 23 to approach each other through the connecting curved rod 24, and the drill tube 23 drives the first locking plate 34 to move, and the first locking plate 34 drives the locking round block 35 to move, so that the locking round block 35 abuts against one side of the locking arc block 36. At this time, the locking round block 35 pushes the locking arc block 36 to rotate to both sides, and the locking arc block 36 squeezes the second spring 38, so that the second spring 38 is elastically deformed and accumulates elastic potential energy. When the locking round block 35 moves to the inner side of the locking arc block 36, the second spring 38 releases the elastic potential energy, and is elastically deformed to push the locking arc block 36 to abut against both sides of the locking round block 35, thereby completing the fixation of the drill tube 23.

[0054] Step 7: Continue to start the hydraulic press 7 in reverse, so that the hydraulic press 7 drives the covering plate 17 to reset through the fertilizer pipe 8, the extrusion shell 9, the extrusion disc 10, the first slider 11, the second slider 12, the connecting rod 13 and the driving rod 14, so that the soil around the fertilizer hole is gathered in the fertilizer hole during the reset of the covering plate 17. At this time, the staff starts the hydraulic press 7, so that the hydraulic press 7 drives the drill tube 23 to move downward through the fertilizer pipe 8, and repeats this step until the fertilizer hole is filled and compacted, thereby completing the precise fertilization of seedlings or trees. Embodiment 2

[0055] See also Figure 3 , Figures 5 to 7As shown, compared with Example 1, as another embodiment of the present invention, the barrier component includes a drill barrel 23 arranged on the inner side of the covering plate 17, two drill barrels 23 are provided, and a third locking component is provided at the top of the drill barrel 23. The drill barrel 23 is slidably installed on both sides of the bottom end of the fertilization pipe 8, and a connecting curved rod 24 is fixedly installed on one side of the drill barrel 23, and a driving block 25 is fixedly installed on the top of the connecting curved rod 24, and a second locking component is provided on one side of the driving block 25; by arranging the barrier component, when it is necessary to dig fertilization holes, the drill barrels 23 are closely attached to each other to block the fertilization pipe 8 from the soil, which can prevent soil from entering the fertilization pipe 8 when digging fertilization holes, affecting the fertilizer discharge, making the fertilizer discharge amount inaccurate, thereby reducing the problem of accuracy of the fertilization system, reducing the impact of the environment on the fertilization pipe 8, and improving the accuracy of the fertilization system.

[0056] See also Figure 3 and Figure 5 As shown, the second locking assembly includes a fixed plate 26 arranged on one side of the driving block 25, a rotating base 27 is fixedly installed on the top of the fixed plate 26, a rotating plate 28 is rotatably installed on one side of the rotating base 27, a torsion spring is arranged at the connection between the rotating base 27 and the rotating plate 28, which can always provide a rotational force for the rotating plate 28, so that the locking tooth block 29 can automatically move toward the direction close to the locking groove 30 when it moves to the top of the locking groove 30, a locking tooth block 29 is fixedly installed on the bottom end of the rotating plate 28, one side of the locking tooth block 29 is abutted against the auxiliary groove 31 and the locking groove 30, and the auxiliary groove 31 and the locking groove 30 are both opened at the top of the driving block 25.

[0057] See also Figure 3 and Figure 5 As shown, one side of the locking tooth block 29 is set as an inclined surface, the other side of the locking tooth block 29 is set as a straight surface, one side of the auxiliary groove 31 is set as an inclined portion, and both sides of the locking groove 30 are set as straight portions, so that when the locking tooth block 29 moves to one side of the auxiliary groove 31, the locking tooth block 29 can be driven to rotate along one side of the auxiliary groove 31 through the inclined surface set between the locking tooth block 29 and the auxiliary groove 31, and when the locking tooth block 29 moves to the inner wall of the locking groove 30, the locking tooth block 29 is abutted against the straight surface set between the locking groove 30 to lock the position of the fixed plate 26.

[0058] See also Figure 3 and Figure 5As shown, the bottom end of the driving block 25 is provided with a T-shaped groove, and the T-shaped groove is opened at the top of the support plate 15. The T-shaped groove is composed of a T-shaped transverse groove 32 and a T-shaped vertical groove 33. When the staff pulls the driving block 25 to move toward the direction close to the fixed plate 26, it can prevent the fixed plate 26 from moving downward due to the action of gravity, causing obstacles to the deployment of the barrier assembly, and when the fixed plate 26 drives the drill tube 23 to fit together through the connecting curved rod 24, the fixed plate 26 can move vertically through the T-shaped transverse groove 32.

[0059] To sum up, by cooperating with the blocking component and the second locking component, when precise fertilization is required, the staff can pull the driving block 25, so that the driving block 25 drives the drill barrel 23 to separate through the connecting curved rod 24, and at this time, the driving block 25 drives the auxiliary groove 31 to abut against the locking tooth block 29, and the locking tooth block 29 is rotated by the set inclined surface, and when the locking tooth block 29 moves to the top of the locking groove 30, the locking tooth block 29 is moved toward the locking groove 30 by the set torsion spring, thereby fixing the position of the driving block 25, and then locking the position of the drill barrel 23, so as to avoid the problem that the position of the drill barrel 23 is offset and affects the fertilization process.

[0060] See also Figure 6 and Figure 7 As shown, the third locking assembly includes a first locking plate 34 arranged at the top of the drill tube 23, a locking round block 35 is fixedly installed on one side of the first locking plate 34, and locking arc blocks 36 are abutted on both sides of the locking round block 35. The locking arc blocks 36 are rotatably installed on one side of the second locking plate 37, and the second locking plates 37 are fixedly installed on the bottom end of the extrusion shell 9. The protrusion of the locking arc block 36 and the second locking plate 37 are connected by a second spring 38.

[0061] To summarize, through the cooperation between the barrier component and the third locking component, when it is necessary to cover and compact the fertilization holes, the staff can push the driving block 25, so that the driving block 25 drives the drill tube 23 to abut against each other through the connecting curved rod 24, and the drill tube 23 drives the locking block 35 to move toward the locking arc block 36 through the first locking plate 34, so that the locking block 35 moves between the locking arc blocks 36, and the locking arc block 36 is tightly abutted against the two sides of the locking block 35 through the elastic action of the second locking plate 37, thereby completing the locking of the drill tube 23, avoiding the drill tube 23 from loosening and deviating easily during the process of continuously impacting and compacting the holes, which reduces the covering effect of the fertilization holes and affects the fertilizer use effect, thereby improving the stability and reliability of the barrier component.

[0062] Working principle: When it is necessary to accurately fertilize the seedlings or trees, the staff moves the fertilizer rack 1 to the seedlings or trees that need to be fertilized, so that the fertilizer pipe 8 is aligned with the area where fertilization is required. At this time, the staff starts the hydraulic press 7, so that the hydraulic press 7 drives the fertilizer pipe 8 to move downward, the fertilizer pipe 8 drives the extrusion shell 9 to move, the extrusion shell 9 drives the limit block 19 to move, the limit block 19 drives the limit protrusion 18 to move, the limit protrusion 18 drives the extrusion disc 10 to move, the extrusion disc 10 drives the first slider 11 to move, the first slider 11 drives the connecting rod 13 to rotate, so that the other end of the connecting rod 13 drives the first slider 11 to move. The second slider 12 is driven to move, the second slider 12 drives the driving rod 14 to move, the driving rod 14 drives the supporting plate 15 to move, so that the supporting plate 15 is extended, at this time, the hydraulic press 7 continues to drive the fertilization pipe 8 to move, the fertilization pipe 8 drives the extrusion shell 9 to move, the extrusion shell 9 drives the limit block 19 to move, the limit block 19 abuts against the limit protrusion 18, so that the limit block 19 rotates with the rotating shaft 20 as the axis, so that the limit block 19 moves to one side of the limit protrusion 18 and stops abutting against the limit protrusion 18, and at the same time, the fertilization pipe 8 drives the drill tube 23 to move, so that the fertilization hole is excavated through the drill tube 23;

[0063] When it is necessary to fertilize the fertilization holes, the staff starts the hydraulic press 7 in reverse, so that the hydraulic press 7 drives the bottom end of the drill tube 23 to move to the same level as the ground through the fertilization tube 8. At this time, the staff pulls the driving block 25 to both sides, so that the driving block 25 drives the connecting curved rod 24 to move, and the connecting curved rod 24 drives the drill tube 23 to move away from the fertilization tube 8. At this time, the auxiliary groove 31 abuts against the locking tooth block 29 and pushes the locking tooth block 29 to rotate, so that the locking tooth block 29 moves to the inner wall of the locking groove 30 when the driving block 25 abuts against the fixing plate 26, thereby completing the positioning of the drill tube 23. At this time, the staff starts the fertilizer storage box 4, removes a precise amount of fertilizer from the fertilizer storage box 4, and discharges it into the fertilizer holes through the conveying pipe 5, the working box 6 and the fertilization tube 8;

[0064] When it is necessary to cover the fertilization holes with soil, the staff pushes the driving block 25, so that the driving block 25 drives the drill tube 23 to approach each other through the connecting curved rod 24, and the drill tube 23 drives the first locking plate 34 to move, and the first locking plate 34 drives the locking round block 35 to move, so that the locking round block 35 abuts against one side of the locking arc block 36. At this time, the locking round block 35 pushes the locking arc block 36 to rotate to both sides, and the locking arc block 36 squeezes the second spring 38, so that the second spring 38 undergoes elastic deformation and accumulates elastic potential energy. When the locking round block 35 moves to the inner side of the locking arc block 36, the second spring 38 releases the elastic potential energy, and the elastic deformation pushes the locking The arc block 36 abuts against both sides of the locking round block 35, thereby completing the fixation of the drill tube 23. At this time, the staff can start the hydraulic press 7 in reverse, so that the hydraulic press 7 drives the covering plate 17 to reset through the fertilizer pipe 8, the extrusion shell 9, the extrusion disc 10, the first slider 11, the second slider 12, the connecting rod 13 and the driving rod 14, so that during the resetting process of the covering plate 17, the soil around the fertilizer hole is gathered in the fertilizer hole. At this time, the staff starts the hydraulic press 7, so that the hydraulic press 7 drives the drill tube 23 to move downward through the fertilizer pipe 8, and repeats this step until the fertilizer hole is filled and compacted, thereby completing the precise fertilization of seedlings or trees.
