Description

Technical Field

[0001] The invention belongs to the technical field of tree planting, and in particular relates to a tree planting and afforestation seedling raising device. Background Art

[0002] Afforestation and seedling cultivation refers to the ecological engineering activities of restoring or expanding forest vegetation by scientifically cultivating seedlings (such as sowing, cutting, grafting, etc.), from seed treatment to seedling management, to ensure that the seedlings are strong and adapted to the local environment, and to plant trees on suitable land.

[0003] In the current tree planting and afforestation seedling production, seedlings cultivated in seedling trays need to be transplanted after completing the growth cycle. However, the root systems of seedlings of some varieties (such as deep-rooted tree species) develop vigorously during the seedling cultivation process, forming a tight fit with the inner wall of the seedling trough. This physiological adhesion phenomenon requires a large external force to be applied in the process of manual or mechanical seedling removal to completely remove the seedlings. In this process, the fibrous root system of the seedlings is very easy to break, and the main root may also suffer varying degrees of mechanical damage. This physical damage will not only destroy the integrity of the root system, but also significantly reduce the water and nutrient absorption capacity of the seedlings after transplanting, ultimately affecting their survival rate and initial growth performance in the new planting site. Therefore, a tree planting and afforestation seedling device is proposed. Summary of the Invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a tree planting and afforestation seedling raising device, which solves the problem that the roots of the existing seedlings form a tight fit with the inner wall of the seedling raising trough during the seedling raising process, external force is required to remove the seedlings completely, and the fibrous root system is very easy to break, which reduces the water and nutrient absorption capacity of the seedlings after transplanting.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a tree planting and afforestation seedling raising device, comprising a base, and further comprising: A seedling raising component, which is fixed inside the base and is used for raising seedlings; a valve assembly, the valve assembly being disposed inside the base; A plastic film is placed on top of the base and is used to separate the soil from the seedling raising component; A pulling component is installed on the base and is used to clamp the periphery of the plastic film; The seedling raising assembly includes a cultivation basin fixed inside the base, a docking hole communicating with the cultivation basin is opened on the top of the base, and the inner diameter of the cultivation basin gradually decreases from top to bottom; The outer circumference and diameter of the plastic film are both larger than the top of the base; The plastic film is placed on the top of the base and the middle part is sleeved on the outside of the valve assembly, so that the plastic film forms a groove in the cultivation pot under the action of the soil, which is used for separating the soil and the cultivation pot.

[0006] Preferably, the cultivation pot is annularly and equiangularly provided with a support rubber pad, and a shunt pipe is fixed to the outside of the cultivation pot and communicates with the support rubber pad through a connecting pipe.

[0007] Preferably, the valve assembly comprises a guide pipe fixed to the middle part of the base, and a corrugated cover is fixed to the bottom of the guide pipe, and the shunt pipe communicates with the inside of the guide pipe through a first communicating pipe. A gas cylinder for retracting and releasing the corrugated cover is fixed to the bottom of the base. The inside of the corrugated cover is initially compressed to make the support rubber pad in an inflated state.

[0008] Preferably, the inside of the guide pipe movably sleeves a valve block through a mandrel, and the inside of the guide pipe is provided with a reset spring for upwardly supporting the valve block, so that the valve block is used for blocking the first communicating pipe.

[0009] Preferably, the inside of the corrugated cover is compressed to make the valve block move upwardly and compress the reset spring, so that the gas enters the support rubber pad through the first communicating pipe. When the gas cylinder pulls the corrugated cover to move downwardly, the valve block blocks the first communicating pipe under the action of the reset spring.

[0010] Preferably, an exhaust groove is formed in the top end of the valve block, and the exhaust groove corresponds to the first communicating pipe under the action of the reset spring. The mandrel is pressed to make the first communicating pipe communicate with the exhaust groove, and the support rubber pad is reset by its elasticity, and the gas in the support rubber pad is discharged through the exhaust groove.

[0011] Preferably, an exhaust hole is formed in the inside of the valve block, and the exhaust hole is in a "J" shape. Initially, the exhaust hole is located at the lower end of the first communicating pipe under the action of the reset spring, and the exhaust hole is located at the included angle between two adjacent exhaust grooves.

[0012] Preferably, the valve assembly comprises a second communicating pipe connected to the bottom of the cultivation pot, the other end of the second communicating pipe communicates with the inside of the guide pipe, and a one-way valve is arranged on the second communicating pipe.

[0013] Preferably, the pulling assembly comprises a C-shaped frame fixed to the outside of the base, a pressing ring is connected to the C-shaped frame through a spring telescopic rod, and a hook for hanging the plastic film is arranged on the top of the pressing ring.

[0014] Preferably, the bottom of the pressure ring is connected to a transmission frame via a connecting rod, and the transmission frame is provided with a through hole corresponding to the cultivation basin; An arc-shaped plate is fixedly mounted on the outside of the supporting rubber pad, and the through hole is sleeved on the outside of the arc-shaped plate; An upper support plate and a lower support plate are fixedly mounted on the upper and lower ends of the support rubber pad, respectively. The arc-shaped plate is inclined, and the inclination direction is consistent with that of the support rubber pad. The arc-shaped plate moves between the upper supporting plate and the lower supporting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention places a plastic film on the top of the base so that the plastic film forms a planting groove in the cultivation pot. The soil and the cultivation pot are separated by the plastic film, and the seeds can be placed in the soil of the groove for seedling cultivation. After the seedlings are grown, the plastic film is cut with a cutting tool such as a utility knife or scissors so that each groove forms an independent individual. The seedlings in the cultivation pot can be taken out through the independent grooves formed by the plastic film, thereby preventing the root system of the seedlings from developing vigorously during the seedling cultivation process and forming a tight fit with the inner wall of the seedling groove, which would cause excessive force during the removal process to cause the fibrous roots to break, thereby improving the water and nutrient absorption capacity of the seedlings during transplantation and ensuring the survival rate of the seedlings. The present invention pushes the bellows upward by using a cylinder, and injects the gas in the bellows into the shunt pipe through the guide pipe and the first connecting pipe, and then enters the supporting rubber pad through the connecting pipe, so that the supporting rubber pad is in an expanded state, and the plastic film forms a planting groove located in the cultivation pot. The space inside the cultivation pot is reduced by the expansion of the supporting rubber pad, and the plastic film is attached to the inner wall of the cultivation pot and the supporting rubber pad. When the seedlings are transplanted, the gas in the supporting rubber pad is discharged, and the volume inside the cultivation pot is increased, so that the plastic film and the seedlings are more easily separated from the cultivation pot. The present invention rotates the core shaft and the valve block so that the exhaust hole and one of the first connecting pipes remain vertical, and then the core shaft and the valve block are lifted up to connect the exhaust hole with one of the first connecting pipes, and the gas in one of the supporting rubber pads is discharged through the exhaust hole, and then one of the seedlings can be removed; The present invention pushes the bellows through the cylinder to inject the gas inside it into the supporting rubber pad. During the injection process, the one-way valve in the second connecting pipe is in a closed state, and the gas can enter the supporting rubber pad normally. When the cylinder stretches the bellows, the valve block blocks the first connecting pipe, and air is extracted from the second connecting pipe and the cultivation pot through the bellows. Since the plastic film is located at the top of the base, by extracting air from the inside of the cultivation pot, a negative pressure is formed between the plastic film and the cultivation pot, and the plastic film can form a planting groove corresponding to the cultivation pot.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention provides a tree planting and afforestation seedling raising device, such as Figure 1-2 , including a base 1, and further comprising: The seedling raising component 2 is fixed inside the base 1 and is used for raising seedlings; The valve assembly 3 is arranged inside the base 1; A plastic film 5 is placed on the top of the base 1 to separate the soil from the seedling raising component 2; The pulling component 4 is mounted on the base 1 and is used to clamp the outer periphery of the plastic film 5; The seedling raising assembly 2 includes a cultivation basin 21 fixed inside the base 1. The top of the base 1 is provided with a docking hole connected to the cultivation basin 21. The inner diameter of the cultivation basin 21 gradually decreases from top to bottom. The outer circumference and diameter of the plastic film 5 are both larger than the top of the base 1; The plastic film 5 is placed on the top of the base 1 , and the middle part is sleeved on the outside of the valve assembly 3 . Under the action of the soil, the plastic film 5 forms a groove in the cultivation pot 21 to separate the soil from the cultivation pot 21 .

[0020] Preparation before seedling cultivation: Place the plastic film 5 on the top of the base 1, with the middle part sleeved on the outside of the valve assembly 3, and clamp the outer periphery of the plastic film 5 by the pulling assembly 4. At this time, place the seedling soil on the top of the plastic film 5. Since the cultivation pot 21 is connected to the through hole of the base 1, and since the outer periphery and diameter of the plastic film 5 are larger than the top of the base 1, under the action of the gravity of the soil, the plastic film 5 forms a planting groove in the cultivation pot 21, so that the soil and the cultivation pot 21 are separated by the plastic film 5, and the seeds can be placed in the soil in the planting groove for seedling cultivation. The specific steps of seedling cultivation are not repeated here; Transplanting: After the seedlings are grown, the plastic film 5 is cut with a cutting tool such as a utility knife or scissors so that each groove forms an independent individual. The seedlings in the cultivation pot 21 can be taken out through the independent grooves formed by the plastic film 5. At the same time, since the inner diameter of the cultivation pot 21 gradually decreases from top to bottom, the efficiency of seedling removal is improved, and the root system of the seedlings is prevented from developing vigorously during the seedling cultivation process and forming a tight fit with the inner wall of the seedling trough, resulting in excessive force during the removal process and the breakage of the fibrous roots. This improves the water and nutrient absorption capacity of the seedlings during transplantation and ensures the survival rate of the seedlings. After the seedlings are removed, the roots of the seedlings are wrapped in a cut plastic film 5. Ties or ropes are used to wrap the roots of the seedlings with the plastic film 5 to protect them, thereby ensuring the survival rate of the seedlings. It should be noted that the plastic film 5 can also be replaced with a starch-based film. Starch-based film is a degradable material that allows for direct transplanting, improving seedling planting efficiency while reducing environmental pollution.

[0021] like Figure 2-Figure 6 As shown, in order to better implement the present invention, a supporting rubber pad 22 is provided in a circular shape at equal angles on the cultivation basin 21, and a shunt pipe 23 is fixed on the outside of the cultivation basin 21. The shunt pipe 23 is connected to the supporting rubber pad 22 through a connecting pipe 24.

[0022] like Figure 6As shown, the valve assembly 3 includes a guide tube 31 fixed to the middle of the base 1, a bellows 36 is fixed to the bottom of the guide tube 31, and the diverter pipe 23 is connected to the interior of the guide tube 31 through the first connecting pipe 25; The bottom of the base 1 is fixed with a cylinder for retracting and releasing the bellows 36; Initially, the gas inside the bellows 36 is compressed by the cylinder and enters the supporting rubber pad 22, so that the supporting rubber pad 22 is in an expanded state.

[0023] During use, the bellows 36 is pushed upward by the cylinder, and the gas in the bellows 36 is injected into the shunt pipe 23 through the guide pipe 31 and the first connecting pipe 25, and then enters the supporting rubber pad 22 through the connecting pipe 24, so that the supporting rubber pad 22 is in an expanded state. Under the action of the gravity of the soil, the plastic film 5 forms a planting groove located in the cultivation pot 21. At this time, the space inside the cultivation pot 21 is reduced by the expansion of the supporting rubber pad 22, and the plastic film 5 is attached to the inner wall of the cultivation pot 21 and the supporting rubber pad 22. When transplanting the seedlings, the gas in the supporting rubber pad 22 is discharged, and the volume inside the cultivation pot 21 is increased, making it easier for the plastic film 5 and the seedlings to be separated from the cultivation pot 21. At the same time, by expanding the volume inside the supporting rubber pad 22, the plastic film 5 forms a planting groove inside the supporting rubber pad 22, which fits against the inner wall of the cultivation pot 21 under the action of the soil, thereby increasing the volume inside the planting groove. At this time, the soil in the planting groove becomes loose, which facilitates the separation of the plastic film 5 from the soil.

[0024] like Figure 3 and Figure 4 As shown, further to better implement the present invention, a valve block 34 is movably sleeved inside the guide tube 31 through a core shaft 32, and a return spring 33 is provided inside the guide tube 31 to support the valve block 34 downward, so that the valve block 34 is used to block the first connecting pipe 25; The bellows 36 moves upward to compress the internal gas into the guide tube 31, pushing the valve block 34 upward to compress the return spring 33, allowing the gas to enter the support rubber pad 22 through the first connecting tube 25; When the cylinder pulls the bellows 36 downward to reset, the valve block 34 blocks the first connecting pipe 25 under the action of the reset spring 33 .

[0025] During use, the bellows 36 is compressed by the cylinder, so that the gas in the bellows 36 enters the guide tube 31, and the valve block 34 is pushed upward by the air pressure to compress the return spring 33, so that the first connecting tube 25 is connected with the interior of the guide tube 31. The gas can enter the supporting rubber pad 22 through the first connecting tube 25, the diverter pipe 23 and the connecting pipe 24, so that the supporting rubber pad 22 is in an expanded state.

[0026] like Figure 3、 Figure 4 and Figure 6 The top of the valve block 34 is provided with an exhaust groove 35 , and the exhaust groove 35 is kept corresponding to the first connecting pipe 25 under the action of the return spring 33 ; The core shaft 32 and the exhaust groove 35 are pressed downward to connect the first connecting pipe 25 with the exhaust groove 35 . The supporting rubber pad 22 is reset by its own elasticity, and the gas inside is discharged through the exhaust groove 35 .

[0027] The seedlings need to be transplanted and taken out. At this time, the core shaft 32 and the valve block 34 are pressed down and the reset spring 33 is stretched, and the exhaust groove 35 is connected to the first connecting pipe 25. Since the supporting rubber pad 22 is made of rubber material, it has its own shrinkage elasticity, so that the gas in the supporting rubber pad 22 is discharged in the opposite direction through the connecting pipe 24, the diversion pipe 23 and the first connecting pipe 25, so that the supporting rubber pad 22 shrinks and resets, increasing the volume in the cultivation pot 21, so that the planting groove formed by the independent plastic film 5 and the seedlings can be easily separated from the cultivation pot 21.

[0028] like Figure 7 and Figure 8 As shown, the valve block 34 is provided with an exhaust hole 39 in a "J" shape; The initial exhaust hole 39 is located at the lower end of the first communicating pipe 25 under the action of the return spring 33 , and the exhaust hole 39 is located at the angle between two adjacent exhaust grooves 35 .

[0029] When an independent seedling needs to be taken out, the core shaft 32 and the valve block 34 are rotated to keep the exhaust hole 39 and one of the first connecting tubes 25 vertical. The core shaft 32 and the valve block 34 can be lifted up to connect the exhaust hole 39 with one of the first connecting tubes 25. The gas in one of the supporting rubber pads 22 is discharged through the exhaust hole 39, and then one of the seedlings can be removed.

[0030] Furthermore, a red indicator line corresponding to the exhaust hole 39 is provided on the top of the core shaft 32. During the rotation of the core shaft 32 and the valve block 34, the red indicator line is used to determine whether the exhaust hole 39 and one of the first connecting pipes 25 remain vertical. At the same time, an indicator line is provided on the outside of the core shaft 32 , and by pulling up the core shaft 32 and the valve block 34 , it is determined according to the indicator line whether the exhaust hole 39 is overlapped and connected with the first connecting pipe 25 .

[0031] like Figure 4 、 Figure 6 and Figure 9 As shown, in order to better implement the present invention, the valve assembly 3 includes a second connecting pipe 37 connected to the bottom of the cultivation basin 21, the other end of the second connecting pipe 37 is connected to the guide pipe 31, and a one-way valve 38 is provided on the second connecting pipe 37.

[0032] During use, the bellows 36 is pushed by the cylinder to inject the gas inside it into the supporting rubber pad 22. During the injection process, the one-way valve mechanism in the second connecting pipe 37 is in a closed state, and the gas can enter the supporting rubber pad 22 normally. When the cylinder stretches the bellows 36, the valve block 34 blocks the first connecting pipe 25, and air is extracted from the second connecting pipe 37 and the cultivation pot 21 through the bellows 36. Since the plastic film 5 is located at the top of the base 1, by extracting air from the inside of the cultivation pot 21, a negative pressure is formed between the plastic film 5 and the cultivation pot 21, and the plastic film 5 can form a planting groove corresponding to the cultivation pot 21. The soil is placed in the planting groove so that the plastic film 5 fits the inner wall of the cultivation pot 21, and seedlings can be grown in the soil.

[0033] like Figure 4 、 Figure 9 and Figure 10 As shown, in order to better implement the present invention, the pulling component 4 includes a C-shaped frame 47 fixed to the outside of the base 1, and a pressure ring 49 is connected to the C-shaped frame 47 through a spring telescopic rod 48. The top of the pressure ring 49 is provided with a hook 40 for hanging the plastic film 5.

[0034] like Figure 9 and Figure 10 As shown, the bottom of the pressure ring 49 is connected to the transmission frame 44 through a connecting rod 46, and the transmission frame 44 is provided with a through hole 45 corresponding to the cultivation basin 21; The outer portion of the supporting rubber pad 22 is fixedly mounted with an arc-shaped plate 41 , and the through hole 45 is sleeved on the outer portion of the arc-shaped plate 41 ; The upper and lower ends of the support rubber pad 22 are respectively fixed with an upper support plate 43 and a lower support plate 42. The arc-shaped plate 41 is inclined, and the inclination direction is consistent with the support rubber pad 22. The arc-shaped plate 41 moves between the upper support plate 43 and the lower support plate 42 .

[0035] When in use, the plastic film 5 is placed on the top of the base 1, and the outer periphery passes through the bottom of the pressure ring 49 and is hung on the hook 40. It is initially expanded by injecting air into the supporting rubber pad 22. During the expansion process, the supporting rubber pad 22 pushes the arc plate 41 to expand outward between the upper support plate 43 and the lower support plate 42. Since the arc plate 41 is inclined and cooperates with the through hole 45, it pushes the transmission frame 44 to move downward, and the pressure ring 49 is pulled downward by the connecting rod 46 to clamp the outer periphery of the plastic film 5 between the base 1 and the pressure ring 49, ensuring the sealing between the plastic film 5 and the base 1, and then ensuring that the plastic film 5 fits into the cultivation pot 21 under the action of negative pressure to form a planting groove.
