Description

Technical Field

[0001] This invention relates to the field of vegetation insulation technology, and in particular to a winter insulation device and method for peach seedlings in northern regions. Background Technology

[0002] Winters in northern regions are cold, with temperatures often below freezing and frequent extreme weather events such as cold waves and frost damage. Peach seedlings have weak cold resistance in their branches and roots, making them susceptible to frost damage during winter. This can severely impact the survival and subsequent growth of the seedlings, even causing large-scale seedling death and significant economic losses for peach growers. Therefore, winter insulation for peach seedlings is a crucial aspect of peach cultivation in northern regions.

[0003] Currently, the common method for winter insulation of peach seedlings in northern regions is to pile soil around the branches near the ground. This utilizes the soil's heat-insulating properties to block cold air and protect the branches and roots from frost damage. However, this method requires manual compaction of the piled soil to eliminate gaps and prevent cold air from penetrating to the roots, thus avoiding root damage from freezing.

[0004] However, there are obvious defects in manual soil compaction. The strength and method of manual operation vary, resulting in inconsistent soil height and uneven protection for peach seedlings. In some areas, gaps may still exist in the soil, making it easy for cold air to penetrate. This leads to unstable soil insulation, poor winter protection for peach seedlings, and an inability to effectively resist extreme low temperatures in winter, making it difficult to meet the needs of large-scale and standardized winter insulation for peach seedlings in northern regions.

[0005] Therefore, this application proposes a winter insulation device and method for peach seedlings in northern regions. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems by proposing a winter insulation device and method for peach seedlings in northern regions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A winter insulation device for peach seedlings in northern regions includes two shells covering the outside of the peach seedlings. The bottom of each shell is fixed with a semi-circular plate. The two semi-circular plates are tightly abutted together by a fixing ring with a first notch, so that the two shells form a conical cylinder when they abut together. Multiple soil-breaking blades of different heights are fixed to the inner wall of the fixing ring, and multiple crushing blades are fixed to the inner wall of the semi-circular plates.

[0009] Rotate the two shells and insert the fixing ring into the soil. Use a soil-breaking knife to break up the soil and accumulate it inside the two shells, so that the soil mound wraps around the outside of the peach seedling.

[0010] Preferably, the outer wall of the semicircular plate is provided with a first annular groove, and the inner wall of the fixing ring is provided with a second annular groove. When the fixing ring is sleeved on the outside of the two semicircular plates, the first annular groove and the second annular groove abut against each other, and the inner wall of the semicircular plate and the inner wall of the fixing ring are on the same circumferential surface.

[0011] A protrusion is fixed on the side wall of the first annular groove, and an L-shaped groove is provided through the fixing ring. The upper end of the L-shaped groove passes through the fixing ring. When the protrusion is located in the L-shaped groove and abuts against the end of the L-shaped groove, the fixing ring is connected to the semi-circular plate by the first bolt.

[0012] Preferably, the lower outer wall of the fixing ring is provided with an annular inclined surface, and an annular cutter is formed between the annular inclined surface and the fixing ring.

[0013] Preferably, the inner wall of the housing is provided with a mounting groove, the mounting groove is provided with a mounting block, the mounting block is fixed in the mounting groove by a second bolt, and a plurality of breaking rods are fixed on the mounting block.

[0014] Preferably, a handle is fixed to the outer wall of the housing, and an anti-slip sleeve is fixed to the outer wall of the handle.

[0015] Preferably, the cone-shaped cylinder formed by the two shells abutting each other has an opening at both the upper and lower ends, and the shells are made of stainless steel.

[0016] Preferably, a transparent arc-shaped plate is fixed to the inner wall of the shell, and a detachable airbag is provided on the inner side wall of the transparent arc-shaped plate. When the two shells are in contact, the two transparent arc-shaped plates are in contact, the two airbags are in contact, and the two airbags form a receiving hole for accommodating peach seedlings.

[0017] Preferably, it further includes a fixing member, which includes a connecting plate welded to the upper end of the housing. When two connecting plates abut each other, they form a connecting ring. The outer wall of the connecting plate is provided with a plurality of limiting grooves arranged along the axial direction. A fixing hoop with a second notch is slidably connected to the outer wall of the connecting plate. A plurality of limiting strips are fixed to the inner side wall of the fixing hoop. The limiting strips slide in cooperation with the limiting grooves.

[0018] Preferably, the soil-breaking blade is located below the crushing blade, and the plurality of soil-breaking blades and the plurality of crushing blades are distributed in a spiral shape.

[0019] This invention also discloses a method for overwintering and heat preservation of peach seedlings in northern regions, the method specifically being:

[0020] S1, cover the peach seedling with two shells and make the two shells abut against each other, abut the fixing ring against the ground, then put the fixing ring on the two semicircular plates, so that the protrusion is located in the L-shaped groove, fix the fixing ring on the semicircular plate with the first bolt, then put the fixing hoop on the outside of the connecting plate, then add soil to the two shells through the position of the airbag until the inside of the shell is filled, and then install the airbag.

[0021] S2, then press down the handle and drive the handle to rotate the housing and the fixing ring. The rotation of the housing and the fixing ring drives the soil breaking blade and the breaking blade to rotate. The rotation of the soil breaking blade can cause the fixing ring to move down and break the soil. The rotation of the soil breaking blade and the breaking blade can mix the soil at the roots of the peach seedling with the added soil.

[0022] S3 continuously drives the handle to rotate the housing and fixing ring, causing the soil to wrap around the outside of the peach seedling.

[0023] Compared with the prior art, the beneficial effects of this invention are as follows:

[0024] 1. Through mechanized breaking, crushing and piling operations, the soil around the peach seedlings is uniformly broken and evenly mixed with the newly added soil. This effectively eliminates soil gaps, prevents cold air infiltration, solves the problem of unstable heat preservation caused by manual operation, and effectively resists the frost damage to peach seedlings caused by extreme low temperatures in northern winters.

[0025] 2. The device is simple to assemble and operate, requiring no complex equipment. Two operators can complete the operation. Compared with the traditional manual soil covering method, it greatly improves the efficiency of winter insulation for peach seedlings, reduces the intensity of manual labor, and meets the needs of large-scale peach tree planting.

[0026] 3. The airbags inside the device form a flexible wrap around the branches and trunks of the peach seedlings to avoid mechanical damage. The transparent arc-shaped plate allows for real-time observation of the internal conditions of the device, enabling timely adjustments to the device's position and soil accumulation, ensuring that the peach seedlings are not subjected to additional damage during the heat preservation process and guaranteeing their subsequent growth.

[0027] 4. The crushing rod adopts a detachable design, and different specifications can be replaced according to the thickness of the peach seedlings and the soil hardness. The air bag can adapt to the branches of peach seedlings of different thicknesses. The whole device can be adapted to the winter insulation needs of peach seedlings at different growth stages, and has a wide range of applications.

[0028] 5. This device also has the benefit of winter tillage, combining winter tillage with winter protection and avoiding cold air. At the same time, this device descends vertically 5-10cm into the ground, digging out some soil from the inner surface of the shell during descent. The purpose of digging is to mix it with the newly added soil. After digging, the shell and the surface are embedded in each other, and the broken soil is only inside the shell and will not affect the internal insulation of the shell due to changes in the external environment.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1-7A winter insulation device for peach seedlings in northern regions includes two symmetrically arranged shells 1. When the two shells 1 are closed, they form a conical cylinder structure with openings at both the top and bottom. The conical cylinder design facilitates the accumulation of soil inside while reducing the accumulation of cold air within the cylinder. It also adapts to the gradual thickening of peach seedlings from the roots to the branches, allowing the soil to adhere to different parts of the seedling for complete insulation. The shells 1 are made of stainless steel, possessing good structural strength, corrosion resistance, and cold resistance, enabling them to withstand the harsh outdoor environment of northern winters and preventing deformation or damage due to low temperatures and soil corrosion, thus extending the device's service life.

[0039] A heat insulation pad can be fixed to the outer wall of the housing 1 with glue or the like to reduce the heat exchange between the housing 1 and the outside air.

[0040] Both shells 1 have a single, integrally formed semi-circular plate 16 fixed to their bottoms. The two semi-circular plates 16 abut against each other to form a complete circular plate, which fits the lower end of the conical cylinder formed by the shells 1. A fixing ring 2 with a first notch is fitted onto the outside of each of the two semi-circular plates 16. The fixing ring 2 can engage with the connection point of the two semi-circular plates 16 through the first notch, achieving a tight clamp fixation of the two semi-circular plates 16, thereby ensuring stable contact between the two shells 1 and preventing loosening or separation during rotation and soil covering. When the shell 1 covers the peach sapling, the first notch on the fixing ring 2 can accommodate the peach sapling, allowing the fixing ring 2 to be smoothly fitted onto the outside of the two semi-circular plates 16 after the shell 1 is placed over the peach sapling.

[0041] The inner wall of the fixed ring 2 is fixed with multiple soil-breaking blades 19 of varying heights, and the inner wall of the semi-circular plate 16 is fixed with multiple crushing blades 20. The soil-breaking blades 19 are located below the crushing blades 20, and the multiple soil-breaking blades 19 and multiple crushing blades 20 are all spirally distributed on the corresponding inner walls. The spiral distribution design allows the soil-breaking blades 19 and crushing blades 20 to continuously cut and crush the soil when the device rotates, and can transport the crushed soil upwards. The soil-breaking blades 19 of varying heights can be adapted to soil layers of different hardness and depth, improving the thoroughness of soil crushing, avoiding the accumulation of large soil clods that form gaps, and ensuring the quality of the soil for subsequent wrapping of peach seedlings.

[0042] The outer wall of the semicircular plate 16 is provided with a first annular groove 17, and the inner wall of the fixing ring 2 is provided with a corresponding second annular groove 18. When the fixing ring 2 is sleeved on the outside of the two semicircular plates 16, the first annular groove 17 and the second annular groove 18 abut against each other and fit together. The inner sidewall of the semicircular plate 16 and the inner sidewall of the fixing ring 2 are on the same circumferential surface. This arrangement ensures the connection and fit between the fixing ring 2 and the semicircular plate 16, avoids step-like gaps at the connection that would obstruct soil accumulation, and makes the force on the device more uniform when rotating, preventing excessive local stress from damaging the components.

[0043] A protrusion 10 is fixed on the side wall of the first annular groove 17. An L-shaped groove 9 is opened through the fixing ring 2. The upper end of the L-shaped groove 9 is set vertically through the upper surface of the fixing ring 2, and the lower end is horizontally bent. The protrusion 10 can slide into the groove from the upper opening of the L-shaped groove 9 and slide along the groove to the horizontally bent end. When the protrusion 10 abuts against the end of the L-shaped groove 9, the fixing ring 2 and the semi-circular plate 16 are circumferentially positioned. At this time, the fixing ring 2 can be firmly fixed on the semi-circular plate 16 by the first bolt 8 passing through the fixing ring 2 and the semi-circular plate 16, so as to prevent the fixing ring 2 from circumferentially sliding during the rotation of the device and ensure the stability of the soil breaking and crushing operation.

[0044] The lower outer wall of the fixed ring 2 is machined with an annular inclined surface. An annular cutter 11 is formed between the annular inclined surface and the lower end face of the fixed ring 2. The sharp edge of the annular cutter 11 can cut the surface soil first when the device is pressed down and rotated, reducing the resistance of the fixed ring 2 to insert into the soil, so that the device can move down more smoothly. At the same time, it can initially break the hard soil layer on the surface. In conjunction with the subsequent operation of the soil breaking blade 19 and the crushing blade 20, the soil breaking efficiency can be improved.

[0045] Among them, the root system of peach seedlings in the north is generally shallow, with a vertical depth of less than 1 meter. The core absorbing roots are concentrated in the 10-60 cm soil layer. For fertile, well-drained loam / sand loam: 60-80 cm is the main layer. For ordinary garden soil: 10-60 cm is the dense root zone. Absorbing roots (capillary roots): the vast majority are in the 20-40 cm soil layer.

[0046] It should be noted that the fixing ring 2 in this invention is inserted into the soil to a depth of less than 10 cm. Secondly, since it is for winter protection of peach seedlings, the volume of the shell 1 in this application does not need to be large. For example, the diameter of the fixing ring 2 can be set to 30 cm, and the height of the shell 1 can be 25-35 cm (covering the weakest part of the peach tree's root collar and the lower part of the trunk). Therefore, as the fixing ring 2 moves down with the annular cutter 11, the soil generated by the soil breaking blade 19 can fill the shell 1, thereby protecting the peach seedlings from winter. Moreover, the soil breaking blade 19 and the crushing blade 20 will not damage the roots of the peach tree.

[0047] The inner wall of the housing 1 has an installation groove 21, in which an installation block 22 is movably engaged. The installation block 22 is detachably fixed in the installation groove 21 by a second bolt 24. Multiple breaking rods 23 are fixed on the installation block 22. The breaking rods 23 are distributed vertically or obliquely and extend into the conical cylinder formed by the housing 1. During the rotation of the device and the upward accumulation of soil, the breaking rods 23 can perform secondary breaking of the rising soil, further refining the soil clods. At the same time, they can create a slight stirring and mixing effect on the accumulated soil, preventing the formation of gaps in the soil within the cylinder and ensuring the quality of the soil covering the peach seedlings. The installation block 22 adopts a bolt-detachable connection design, which makes it easy to replace the breaking rods 23 of different lengths and densities according to the thickness of the peach seedlings and the hardness of the soil, improving the adaptability of the device. At the same time, when the breaking rods 23 are worn or damaged, they can be disassembled and replaced individually, reducing the maintenance cost of the device.

[0048] Handles 6 are symmetrically fixed to the outer wall of the shell 1. Anti-slip sleeves 7 are fitted and fixed to the outer wall of the handles 6. The anti-slip sleeves 7 are made of anti-slip and wear-resistant materials such as rubber and silicone, which increases the friction between the operator's hand and the handles 6, prevents the operator from slipping when pressing down or rotating the device, and improves the stability and safety of operation. The symmetrically arranged handles 6 make it easy for two operators to operate together, so that the rotation force of the device is more even, avoids the device from tilting due to force on one side, and ensures the uniformity of soil accumulation.

[0049] A transparent arc-shaped plate 4 is fixed to the inner wall of the shell 1. The transparent arc-shaped plate 4 is made of high-strength transparent plastic or tempered glass, which not only has a certain structural strength, but also allows the operator to observe the position of the peach seedlings and the soil accumulation inside the device through the transparent arc-shaped plate 4. This facilitates timely adjustment of the device position, ensures that the soil accurately covers the peach seedlings, and avoids the peach seedlings not being covered by soil on one side due to device displacement.

[0050] The inner wall of the transparent arc-shaped plate 4 is provided with a detachable airbag 5. The airbag 5 is made of elastic and wear-resistant rubber material. When the two shells 1 abut against each other, the two transparent arc-shaped plates 4 also abut against each other. The two airbags 5 abut against each other simultaneously and enclose to form a receiving hole 14. The main trunk of the peach seedling can be inserted into the receiving hole 14. The outer wall of the airbag 5 is fixed with an installation arc plate. The installation arc plate is fixed to the transparent arc-shaped plate 4 by a buckle or bolt. When in use, the airbag 5 is installed last. In this way, a soil filling cavity is formed between the two transparent arc-shaped plates 4 and the peach seedling so that soil can be added to the shell 1.

[0051] The elastic design of the airbag 5 can adaptively fit the thickness of the peach seedling's trunk, which not only avoids mechanical damage caused by direct contact between the inner wall of the device and the branches of the peach seedling, but also provides flexible fixation for the branches of the peach seedling, preventing relative sliding between the device and the peach seedling during rotation. At the same time, the airbag 5 can fill the gap between the device and the branches of the peach seedling, reducing the intrusion of cold air from the gap and improving the heat preservation effect.

[0052] The device also includes fasteners for fixing the upper ends of the two housings 1. The fasteners include connecting plates 3 welded to the upper end of each housing 1. After the two connecting plates 3 abut against each other, they form a circular connecting ring that fits the upper end of the conical cylinder, ensuring the connection stability of the upper end of the housings 1. The outer wall of the connecting plate 3 has multiple limiting grooves 13 axially distributed. The multiple limiting grooves 13 are evenly distributed circumferentially. A fixing hoop 12 with a second notch is slidably fitted on the outside of the connecting plate 3. The fixing hoop 12 can be engaged at the connection point of the two connecting plates 3 through the second notch. The inner side wall of the fixing hoop 12 is correspondingly fixed with multiple limiting strips 15. The limiting strips 15 correspond one-to-one with the limiting grooves 13 and slide in fit. The second notch on the fixing hoop 12 is used to accommodate peach seedlings so that the fixing hoop 12 can be smoothly fitted onto the outside of the connecting plate 3.

[0053] The design of the limiting strip 15 and the limiting groove 13 not only achieves circumferential positioning of the fixing hoop 12 and the connecting plate 3 to prevent the fixing hoop 12 from sliding, but also limits the axial displacement of the two connecting plates 3, further ensuring the overall stability of the two shells 1 after they are closed, and preventing the upper part of the device from opening or loosening during operation.

[0054] The present invention also discloses a heat preservation method applicable to the above-mentioned winter heat preservation device for peach seedlings in northern regions. The method is simple and convenient to operate, requires no complicated professional skills, and can be mastered by operators after simple training. It can effectively replace the traditional manual soil covering method and improve the efficiency and standardization of winter heat preservation for peach seedlings.

[0055] Currently, before winter, in order to ensure that the soil and water are fertile in winter, a large amount of water is irrigated into the ground to ensure that the soil remains moist even when the winter is dry (because peach trees are afraid of dryness and cold). After irrigation, the soil and water balance is maintained and does not run off. This device can ensure that the above-mentioned soil and water balance is not broken.

[0056] The specific steps are as follows:

[0057] S1. First, select a suitable breaking rod 23 according to the thickness of the main trunk of the peach seedling to be insulated. Then, snap the mounting block 22 into the mounting groove 21 on the inner wall of the shell 1 and tighten the second bolt 24 to firmly fix the breaking rod 23 inside the shell 1. If the airbag 5 is leaking, inflate the airbag 5 in advance to ensure the elasticity and fit of the airbag 5.

[0058] Subsequently, two operators, each holding a handle 6 of the two housings 1, slowly closed the two housings 1 from both sides of the peach sapling, allowing the main trunk of the peach sapling to pass between the two airbags 5, until the two housings 1 were completely in contact, and the two semi-circular plates 16 and the two connecting plates 3 also closed simultaneously; at this time, the two airbags 5 closed to form a receiving hole 14, and the main trunk of the peach sapling was flexibly wrapped in the receiving hole 14. The operators observed the position of the peach sapling through the transparent arc plate 4, and made minor adjustments to the housings 1 to ensure that the peach sapling was in the center of the device and to avoid any deviation.

[0059] Next, the fixing ring 2 is placed on the outside of the peach tree through the first notch, and then it is engaged with the outside of the two semi-circular plates 16, so that the protrusion 10 on the semi-circular plate 16 slides into the groove from the upper opening of the L-shaped groove 9. The fixing ring 2 is rotated horizontally, so that the protrusion 10 slides along the L-shaped groove 9 to the horizontally bent end and abuts against the end, thus completing the circumferential positioning of the fixing ring 2 and the semi-circular plate 16. Then, the first bolt 8 is passed through the fixing ring 2 and the semi-circular plate 16 in sequence, and the first bolt 8 is tightened to realize the tight clamping and fixing of the fixing ring 2 to the two semi-circular plates 16, preventing the lower end of the shell 1 from loosening.

[0060] Finally, the fixing hoop 12 is fitted onto the outside of the peach tree through the second notch, and then locked onto the outside of the two connecting plates 3, so that the limiting strips 15 on the inner side of the fixing hoop 12 slide into the limiting grooves 13 on the outer wall of the connecting plate 3 one by one. The fixing hoop 12 is slid down to the lower end of the limiting grooves 13 to complete the fixing of the upper ends of the two shells 1. At this point, the entire device is assembled and stably fitted onto the outside of the peach seedling.

[0061] Soil is added to both shells 1 through the location of airbag 5 until the interior of shell 1 is filled, and then airbag 5 is installed.

[0062] S2, after filling the soil and installing the airbag 5, the operator holds the handle 6 with both hands and presses the lower end of the fixed ring 2 and the annular cutter 11 against the ground around the roots of the peach seedling to ensure that the device is vertical and avoids tilting.

[0063] Subsequently, the two operators worked together, pressing down on handle 6 with one hand to apply vertical downward pressure to the device, while simultaneously rotating handle 6 in the same direction with the other hand, causing the housing 1, semi-circular plate 16, and fixed ring 2 to rotate synchronously. During the rotation of the device, the annular cutter 11 at the lower end of the fixed ring 2 first cuts the surface soil to reduce soil resistance. The soil-breaking blade 19 on the inner wall of the fixed ring 2 performs spiral cutting and crushing of the soil below as the device rotates. Under the action of the soil-breaking blade 19 and the crushing blade 20, the crushed soil can mix the soil at the roots of the peach seedlings with the added soil and further refine the soil clods.

[0064] In order to avoid damaging the surface roots, a layer of rubber film can be wrapped around the surface of the soil breaking blade 19 and the breaking blade 20.

[0065] Under the rotating cutting action of the soil-breaking blade 19, the device moves downward until most of the fixing ring 2 is inserted into the soil. At this time, the soil around the roots of the peach seedling has been initially broken, preparing for subsequent soil accumulation. Throughout the process, the operator can observe the soil breaking condition through the transparent arc plate 4 and adjust the downward pressure and rotation speed according to the soil hardness. If the soil hardness is high, the rotation speed can be slowed down and the downward pressure increased to ensure thorough soil breaking.

[0066] Finally, the fixing ring 2 and the annular cutter 11 are inserted into the soil.

[0067] S3, continue to press down and rotate the handle 6, the device continues to move slowly down, the soil-breaking blade 19 and the crushing blade 20 continue to crush the soil and enter the conical cylinder formed by the soil surrounding the shell 1. As described above, the present invention can be fixed on the periphery of the peach seedling.

[0068] During the agitation process, the soil will collide and come into contact with the crushing rod 23 inside the shell 1. The crushing rod 23 crushes the soil three times, further refining the remaining large soil clods. At the same time, the rotation and agitation of the crushing rod 23 can mix and stir the accumulated soil, preventing the soil from forming gaps in the cylinder.

[0069] As mentioned above, the soil on the planting land can be tilled. The benefits of tilling the soil in winter are as follows:

[0070] There are many benefits to tilling the land in winter. Many fields are continuously cropped, and the improper application of chemical fertilizers leads to a large amount of undecomposable substances remaining in the soil, causing compaction. Watering and fertilization only reach the surface layer, resulting in low utilization. Tilling brings the lower soil layers to the surface, improving soil structure and making the soil looser, which is more conducive to crop growth.

[0071] Winter temperatures are low, and when the soil is turned up, some pathogens and insect eggs will freeze to death. In the freezing weather, pests and diseases in the soil lack a suitable living environment, so they will be much less prevalent in the spring, reducing the hassle of pest and disease control. If the soil is not turned up, the temperature in the deeper layers is relatively high, providing an overwintering site for insect eggs, resulting in more pests when planting in the spring.

[0072] Deep tillage in orchards can increase the topsoil layer, improve aeration, increase soil moisture content, enhance soil microbial activity, facilitate the decomposition of soil organic matter, and improve soil fertility. At the same time, deep tillage can also prune the root system appropriately, promote the growth of fibrous roots, and expand the total root volume, laying a good foundation for the vigorous growth of trees, lush foliage, and large, high-quality fruit in the following year.

[0073] Winter tilling allows the soil to recover to its optimal state after a winter of moisture replenishment, resulting in a balanced soil structure. As soon as spring arrives and temperatures rise, the fallow land can be directly used for spring sowing, effectively alleviating the pressure of winter tilling and spring sowing.

[0074] S4. After the soil is piled up and wrapped, stop rotating the handle 6, slowly loosen the handle 6, check the fixation of the device, and ensure that the fixing ring 2 and fixing hoop 12 are not loose and the device is stably fitted on the outside of the peach seedling. If it is found that the soil pile is insufficient or there are gaps on one side, fine soil can be added to the inside from the opening at the top of the device and gently tamped with a small wooden stick to ensure the heat preservation effect.

[0075] During the wintering period of peach seedlings, operators can regularly observe the soil and seedling condition through the transparent curved plate 4. If soil settling or falling off is found, soil should be added and compacted in time.

[0076] Once the spring temperatures rise in the north and the peach seedlings have finished their wintering period, reverse shell 1 to remove the entire device from the ground, remove the fixing ring 2 and fixing hoop 12, remove the fixing hoop 12, and finally separate the two shells 1 to the sides to complete the disassembly of the device. The disassembled device can be cleaned, maintained, stored, and reused.

[0077] 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.
