Description

A seedling transplanting device suitable for sandy areas Technical Field

[0001] This utility model relates to the field of desertification control equipment technology, specifically a seedling transplanting device suitable for sandy areas. Background Technology

[0002] Windbreak and sand fixation are the main means of combating desertification. These methods include setting up sand barriers, covering the sand surface with dense materials, and planting psammophytic plants. These three methods are generally used on the windward slopes of sand dunes to stabilize loose sand and reduce dune movement. In desert fringe areas, saplings are transplanted to create windbreaks, reducing wind force and preventing desert expansion.

[0003] However, in sandy soil areas such as deserts and Gobi, the soil is loose and has poor water retention, resulting in a low survival rate for transplanted seedlings. Existing technologies include using biodegradable planting bags to wrap part of the soil for transplanting with the soil intact. The pores on the surface of the planting bags facilitate root extension; however, these bags are relatively thin and prone to premature breakage, offering limited improvement in survival rates. Another technology utilizes biodegradable materials to create water storage boxes. These boxes have a raised, hollowed-out center to store water around the raised area, and a protective lid with a hole in the center. The box is placed over the seedling and covered, using evaporation to keep the area around the plant roots moist. However, the boxes are often shallowly buried, making the lid easily lifted by wind, thus compromising water retention. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a seedling transplanting device suitable for sandy areas.

[0005] The technical solution of this utility model is:

[0006] A seedling transplanting device suitable for sandy areas, comprising:

An external support structure is provided on the outside of the housing for securing the housing with sand and soil. A planting box is threadedly installed inside the housing. The planting box includes a hollow double-layered box body. The inner layer of the double-layered box body contains nutrient soil and a water-retaining material for replenishing the nutrient soil. A protective cover is slidably installed on the top of the double-layered box body to reduce moisture evaporation. The outer shell, double-layered box body, and protective cover are all made of biodegradable materials.

[0008] Preferably, the support structure includes several support plates, which are radially installed on the top of the side of the housing. The ends of the support plates are connected to support rings, and the bottom of the side of the housing is provided with a fixing plate. The outer diameter of the support ring is the same as that of the support plate.

[0009] Preferably, a sand-fixing layer is provided on the outer side of the shell and between the support plate and the fixing plate. The sand-fixing layer becomes sticky after being soaked in water and is used to bind sand. A protective layer is wrapped around the outside of the sand-fixing layer to keep the sand-fixing layer dry and is removed before use.

[0010] Preferably, the double-layer box includes an outer cylinder and an inner cylinder, which are coaxially arranged. The bottom ends of the outer cylinder and the inner cylinder are closed, and a space is left between the bottom ends of the outer cylinder and the inner bottom surface of the shell for water storage.

[0011] Preferably, the bottom surface of the inner cylinder, the bottom side surface of the inner cylinder, and the space between the inner cylinder and the outer cylinder are provided with vent holes. The bottom side surface of the inner cylinder and the bottom surface between the inner cylinder and the outer cylinder are provided with water guiding belts.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please refer to Figures 1-4. The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A seedling transplanting device suitable for sandy areas, comprising:

[0028] The outer shell 1 includes a shell 11. The bottom end face of the shell 11 is provided with several grooves 13. The shell 11 is provided with a support structure on the outside. The support structure is used to fix the shell 11 with sand and soil. The planting box 2 is threadedly installed inside the shell 11. The planting box 2 includes a hollow double-layer box body. The inner layer of the double-layer box body is provided with nutrient soil 24 and water-retaining material 23. The water-retaining material 23 is used to replenish water for the nutrient soil 24. A protective cover 3 is slidably installed on the top of the double-layer box body. The protective cover 3 is used to reduce water evaporation. The outer shell 1, the double-layer box body and the protective cover 3 are all made of biodegradable materials.

[0029] The shell 11 can be made of a composite material of straw fiber and PLA, with straw fiber accounting for 60% and degradation time controlled within 3-6 months.

[0030] The thickness at the groove 13 is relatively low, so the shell 11 will preferentially degrade and create holes at the groove 13 during degradation.

[0031] Water-retaining material 23 can be sodium polyacrylate, which can slowly release water after absorbing it and is biodegradable.

[0032] Nutrient soil 24 is used to provide the necessary nutrients for the early growth of seedlings.

[0033] The support structure includes several support plates 12, which are radially installed on the top side of the housing 11. A support ring 15 is connected to the end of the support plate 12. A fixing plate 14 is provided at the bottom side of the housing 11. The outer diameter of the support ring 15 is the same as that of the support plate 12.

[0034] The support plate 12, the fixing plate 14, the support ring 15, and the housing 11 are made of the same material and are pressed into shape.

[0035] During installation, first dig a planting pit in the sand with a drill bit, then put the shell 11 into the planting pit, and the support ring 15 supports the side wall of the planting pit to ensure that the shell 11 is vertical.

[0036] After the sand is backfilled, the support plate 12 can prevent the shell 11 from moving upward, and at the same time

[0037] A sand-fixing layer 16 is provided on the outside of the shell 11 and between the support plate 12 and the fixing plate 14. The sand-fixing layer 16 becomes sticky after being soaked in water and is used to bind sand. A protective layer 17 is wrapped around the outside of the sand-fixing layer 16. The protective layer 17 is used to keep the sand-fixing layer 16 dry and is removed when used.

[0038] The sand-fixing layer 16 can be made of yellow gelatin. The sand-fixing layer 16 expands when it comes into contact with water, and its own stickiness can bind the sand. The protective layer 17 can be made of release paper. The protective layer 17 is bonded to the sand-fixing layer 16 and can prevent the sand-fixing layer 16 from getting damp when it is not in use.

[0039] The double-layer box includes an outer cylinder 21 and an inner cylinder 22, which are coaxially arranged. The bottom ends of the outer cylinder 21 and the inner cylinder 22 are closed, and a space is left between the bottom ends of the outer cylinder 21 and the inner bottom surface of the shell 11 for water storage.

[0040] The outer cylinder 21 and the inner cylinder 22 are made of the same material as the shell 11 and are pressed into shape.

[0041] The outer bottom of the outer cylinder 21 needs to be threaded, and the outer cylinder 21 and the inner side of the shell 11 are threaded together, which allows for easy adjustment of the distance between the bottom of the outer cylinder 21 and the inner cylinder 22 and the inner bottom surface of the shell 11. This allows for adjustment of the planting depth of the seedlings.

[0042] Ventilation holes 25 are provided on the bottom surface of the inner cylinder 22, the bottom side surface of the inner cylinder 22, and between the inner cylinder 22 and the outer cylinder 21. Water guide belts 26 are provided on the bottom side surface of the inner cylinder 22 and the bottom surface between the inner cylinder 22 and the outer cylinder 21. The water guide belts 26 are made of flexible multi-fiber material and can transfer water by using capillary action.

[0043] The ventilation holes on the bottom of the inner cylinder 22 allow the seedling roots to grow downwards.

[0044] The water guide belt 26 between the inner cylinder 22 and the outer cylinder 21 is used to guide the water stored in the shell 11 to the water-retaining material 23 to replenish the water-retaining material 23.

[0045] The water-guiding strip 26 on the bottom side of the inner cylinder 22 is used to guide the water inside the water-retaining material 23 to the nutrient soil 24 to replenish the nutrient soil 24.

[0046] The water-guiding tape 26 can block the bottom side of the inner cylinder 22 and the ventilation holes 25 between the inner cylinder 22 and the outer cylinder 21, preventing the seedling roots from extending to both sides.

[0047] The protective cover 3 includes a sliding sleeve 31, which is sleeved on the outside of the inner cylinder 22. The top of the sliding sleeve 31 is provided with an inner cover plate 32, and several pre-cut grooves 33 are provided through the inner cover plate 32. The pre-cut grooves 33 are arranged concentrically.

[0048] The protective cover 3 is made of the same material as the shell 11 and is formed by pressing.

[0049] The inner cover plate 32 covers the top surface of the inner cylinder 22 to reduce the evaporation of moisture from the nutrient soil 24.

[0050] The pre-cut groove 33 allows for easy drilling of holes in the inner cover plate 32, and holes can be drilled at different locations in the pre-cut groove 33 depending on the age of the seedling.

[0051] The outer bottom of the sliding sleeve 31 is provided with an outer cover plate 34, and the outer edge of the top surface of the outer cover plate 34 is provided with a sealing ring 35, and the outer side abuts against the inner side of the outer cylinder 21.

[0052] The outer cover plate 34 and the sealing ring 35 are used to seal between the inner cylinder 22 and the outer cylinder 21, reducing the evaporation of moisture from the water-retaining material 23.

[0053] Meanwhile, the area above the outer cover plate 34 and between the inner cylinder 22 and the outer cylinder 21 can be filled with sand to improve the wind resistance of the protective cover 3.

[0054] Working principle:

[0055] Using a known drilling tool, dig planting holes at the desired planting location.

[0056] Remove the protective layer 17 and place the outer shell 1 into the planting hole. During placement, ensure that the support ring 15 is in contact with the side wall of the planting hole to keep the shell 11 vertical.

[0057] After placement, sand is backfilled on the outside of the shell 11 for initial fixation. A certain amount of clean water is poured on the outside of the shell 11. The sand-fixing layer 16 absorbs water and expands, using its own adhesiveness to bond the sand.

[0058] Insert the sapling with soil into the inner cylinder 22, with the bottom touching the nutrient soil 24.

[0059] Insert the planting box 2 with the sapling into the housing 11, and then rotate the planting box 2 to make it threadedly connected to the housing 11. Adjust the height of the planting box 2 to a suitable position.

[0060] Water the roots of the seedling and the water-retaining material 23 to moisten the nutrient soil 24 and expand the water-retaining material 23. Excess water will flow into the space below the planting box 2.

[0061] Depending on the age of the sapling, make an opening at the top of the inner cover plate 32 at the appropriate pre-cut groove 33, align the opening at the top of the inner cover plate 32 with the sapling, and put the sliding sleeve 31 onto the inner cylinder 22.

[0062] Press down on the protective cover 3 so that the inner cover plate 32 abuts against the top surface of the inner cylinder 22.

[0063] At this time, the inner cover plate 32 covers the top surface of the inner cylinder 22, which can reduce the evaporation of moisture from the nutrient soil 24. The outer cover plate 34 and the sealing ring 35 can reduce the evaporation of moisture from the water-retaining material 23.

[0064] Finally, the space between the inner cylinder 22 and the outer cylinder 21 is backfilled with sand to press down the outer cover plate 34 and the sealing ring 35.

[0065] During the seedling's growth, the water in the water-retaining material 23 is slowly injected into the nutrient soil 24 through the water-guiding belt 26, and the water stored inside the shell 11 is slowly injected into the water-retaining material 23 through the water-guiding belt 26, ensuring a continuous water supply to the seedling.

[0066] The roots of the sapling will extend downwards, pass through the vent at the bottom of the inner cylinder 22, and enter the shell 11.

[0067] During the degradation process, the shell 11 will preferentially perforate through the groove 13, allowing the seedling roots to extend downward through the perforation in the groove 13.

[0068] The shell 11, outer cylinder 21, inner cylinder 22 and protective cover 3 will all come into contact with moisture, ensuring that the degradation rate will not decrease due to external drought. At the same time, because the internal humidity is high, degradation will start from the inside first.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
