Description

Technical Field

[0001] This invention relates to the field of planting technology in the Gobi Desert, and in particular to a fixed planting device and method for backfilling Gobi Desert areas with wind and sand. Background Technology

[0002] Rising global temperatures have triggered droughts in some regions, leading to sparse vegetation and infertile soil. This is particularly pronounced in high-altitude areas where desertification (specifically the Gobi desertification) is rampant, making it difficult for vegetation to survive and creating a vicious cycle in desert and Gobi areas. Simultaneously, the area of ​​saline-alkali land continues to expand, severely impacting the human living environment. Only through human intervention, such as planting vegetation, can this vicious cycle be broken and the Gobi ecosystem restored.

[0003] The Gobi Desert is a typical desert landform, with its surface mainly composed of gravel and coarse sand, and a vegetation coverage of less than 5%. Existing planting techniques in the Gobi Desert have two major drawbacks: First, during crop growth, the roots are easily obstructed by the gravel in the Gobi soil as they extend downwards, preventing deep-rooted plants from accessing deep water and nutrients, resulting in a significant decrease in crop survival rates. Second, plants are weak against wind in the early stages of growth, and strong winds in the Gobi Desert can easily blow over seedlings, further reducing the survival rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a fixed planting device and method for backfilling Gobi Desert with wind and sand. This device can provide wind protection for seedlings, remove gravel from the root growth path, and use wind and sand to backfill the roots and improve the survival rate of seedlings in the Gobi Desert environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixed planting device for backfilling Gobi Desert with wind and sand includes a planting cylinder and a dividing component rotatably installed at the bottom of the planting cylinder. The dividing component is inverted conical in shape and consists of several sieve plates connected by rubber connectors. The sieve holes on the sieve plates have a diameter between coarse sand and gravel. A rope loop is installed on the side wall of the planting cylinder, a windbreak component is installed on the planting cylinder, and a rope is installed at the end of the sieve plate. The other end of the rope passes through the rope loop and connects to the windbreak component.

[0006] Furthermore, the windproof assembly includes a baffle sleeve with threads on its inner side, and an outer toothed sleeve is installed on the planting cylinder, with the outer toothed sleeve threadedly connected to the baffle sleeve.

[0007] Furthermore, a connecting ring is rotatably installed at the bottom of the retaining sleeve, one end of the rope is connected to the connecting ring, and the other end passes through the rope sleeve and is connected to the end of the sieve plate; a torsion ring is installed at the top of the retaining sleeve.

[0008] Furthermore, the outer wall of the planting cylinder is equipped with a ring plate, which fits against the ground when the planting cylinder is inserted into the Gobi Desert; the outer wall of the retaining sleeve is equipped with a sand collecting plate, which is inclined towards the ground.

[0009] Furthermore, a retaining edge is installed at the end of the sieve plate; a return spring is installed at the rotating connection between the planting cylinder and the sieve plate.

[0010] This invention also provides a fixed planting method for using wind-blown sand backfill in the Gobi Desert, applied to the above-mentioned planting device, comprising the following steps: Step S1: Loosen the soil in the designated planting area of ​​the Gobi Desert, insert the planting cylinder of any of the fixed planting devices described in claims 1-5 into the planting area until the ring plate is in contact with the ground to complete the installation of the device; Step S2: Plant the seedling in the sand layer inside the planting tube, water the planting tube, guide the water to seep downwards, and encourage the seedling roots to extend to deeper layers. Step S3: Rotate the torsion component of the windbreak assembly to move the protective structure of the windbreak assembly upward to protect the seedling trunk. At the same time, the sieve plate is rotated outward by the rope to remove gravel in the root growth path of the seedling.

[0011] Furthermore, in step S1, when the planting cylinder is inserted into the sand layer, coarse sand enters the interior of the planting cylinder through the sieve holes of the sieve plate, while gravel is blocked by the sieve plate and pushed to the vicinity of the outer wall of the planting cylinder.

[0012] Furthermore, in step S3, when the sieve plate rotates outward, it pushes the gravel in the root growth path toward the ring plate. Under the pressure of the ring plate, the gravel gathers at the bottom of the ring plate and is compacted to form a gravel layer.

[0013] In step S3, the sand collection plate of the windbreak component guides the wind and sand, causing the sand particles in the wind and sand to fill the roots and stems of the seedlings.

[0014] In step S2, the lower half of the planting tube is buried underground and the upper half is exposed above the ground. When watering, the water is guided by the planting tube to penetrate deeper, and the plant's hydrotropism promotes deep root growth.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a rotating torsion ring to move the baffle upwards, which can protect the seedling trunk and prevent strong winds in the Gobi Desert from blowing the seedling down, thus improving the seedling's wind resistance in the early stages of growth.

[0016] 2. During the upward movement of the baffle, the rope is pulled by the adapter ring, which in turn drives the sieve plate to rotate outward. This can remove gravel in the root growth path, prevent gravel from hindering root extension, ensure that deep-rooted plants can obtain deep water and nutrients, and at the same time, the loose sand layer can reduce root growth resistance and accelerate the growth rate of seedlings.

[0017] 3. When the sieve plate rotates outward, it pushes the gravel to the bottom of the ring plate. The gravel is compacted under the pressure of the ring plate to form a gravel layer. This gravel layer can not only fix the sand layer around the plant and reduce the sand particles being blown away by the wind, but also enhance the rainwater infiltration effect due to the large gaps in the gravel, so as to promote the rapid infiltration of rainwater into the root system and improve the plant's ability to obtain water.

[0018] 4. The lower half of the planting tube is buried underground and the upper half is exposed above the ground. When watering, the planting tube can guide water to seep downwards, and the hydrotropism of plants can promote deep root growth, further enhancing the wind resistance of the seedlings. At the same time, the sand collection plate on the outer wall of the cover can guide wind and sand to fill the seedling roots and rhizomes, realizing the utilization of wind and sand resources and improving planting stability.

[0021] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6 As shown, the present invention is a fixed planting device for backfilling Gobi Desert with wind and sand, including a planting cylinder 1.

[0023] In this embodiment, the planting cylinder 1 is made of 3mm thick carbon steel and hot-dip galvanized for corrosion protection. Its overall height is 120cm, with 80cm buried underground and 40cm exposed above ground. The sieve plate 201 is made of stainless steel with a thickness of 2mm. The sieve holes are designed as square holes with a side length of 5mm to ensure that coarse sand can pass through smoothly and gravel is effectively blocked. The rubber connector 202 is made of weather-resistant butyl rubber, which can adapt to the large temperature difference between day and night in the Gobi Desert. The rope 8 is made of high-strength nylon rope with a diameter of 8mm, which has the characteristics of UV resistance and tensile strength. The return spring is made of stainless steel to avoid corrosion in the saline-alkali environment of the Gobi Desert. The outer toothed sleeve 7 is made of alloy material to ensure the threaded connection strength with the retaining sleeve 301.

[0024] like Figures 1-3 As shown, a dividing component 2 is rotatably installed at the bottom of the planting cylinder 1. The dividing component 2 is inverted conical and is composed of six screen plates 201 spliced ​​together. Adjacent screen plates 201 are fixed together by rubber connectors 202. The rubber connectors 202 can also achieve flexible connection between the screen plates 201, ensuring the rotation space of the screen plates 201. A return spring is installed at the rotatable connection between the planting cylinder 1 and the screen plate 201. In the initial state, the return spring can keep the dividing component 2 inverted conical shape, improving the soil breaking ability of the planting cylinder 1 when inserted into the sand layer. Three rope loops 6 are welded to the side wall of the planting cylinder 1 in a ring shape. The bottom of the loop 301 is rotatably installed with a transition ring 303 through a bearing. One end of the rope 8 is tied to the transition ring 303, and the other end passes through the rope loop 6 and is tied to the end of the screen plate 201. A ring plate 4 is welded to the outer wall of the planting cylinder 1. The diameter of the ring plate 4 is larger than the diameter of the planting cylinder 1. After the planting cylinder 1 is inserted into the Gobi Desert, the ring plate 4 can fit against the ground, limiting the insertion depth of the planting cylinder 1, and at the same time forming a pressure resistance against the gravel.

[0025] like Figures 4-5 As shown, the inner side of the baffle sleeve 301 of the windbreak assembly 3 has an internal thread, and the upper part of the planting cylinder 1 is welded with an outer toothed sleeve 7. The outer side of the outer toothed sleeve 7 has an external thread that matches the internal thread of the baffle sleeve 301, and the baffle sleeve 301 and the outer toothed sleeve 7 are threadedly engaged. A torsion ring 302 is welded to the top of the baffle sleeve 301 to facilitate the operator to rotate the baffle sleeve 301. Two symmetrically distributed sand collecting plates 5 are welded to the outer wall of the baffle sleeve 301. The sand collecting plates 5 are inclined towards the ground at an angle of 45°, which can effectively guide the wind and sand to flow towards the roots of the seedlings. The end of the sieve plate 201 is welded with an arc-shaped baffle, which can concentrate gravel on the surface of the sieve plate 201 when the sieve plate 201 rotates, thereby improving the efficiency of gravel collection and pushing.

[0026] The installation process of this device is as follows: First, use a soil loosening machine to loosen the soil in the designated planting area of ​​the Gobi Desert, controlling the loosening depth to 100cm. After loosening, vertically insert the planting cylinder 1 into the planting area, with the separating component 2 making initial contact with the sand layer. Figure 6As shown, during the insertion process, coarse sand in the sand layer enters the planting cylinder 1 through the square sieve holes of the sieve plate 201, while gravel is blocked by the sieve plate 201. As the planting cylinder 1 goes deeper, the gravel is pushed to the vicinity of the outer wall of the planting cylinder 1 by the inverted conical separating component 2 until the ring plate 4 is completely in contact with the ground, thus completing the installation and fixing of the device.

[0027] The planting and irrigation process is as follows: After the device is installed, the lower half of the planting cylinder 1 is buried underground and the upper half is exposed above the ground. The seedlings are transplanted into the sand layer inside the planting cylinder 1. Water is slowly poured into the planting cylinder 1, with the total amount of water controlled at 20L per seedling. After the water enters the sand layer inside the planting cylinder 1, it penetrates deeper under the guidance of the planting cylinder 1. By utilizing the hydrotropism of plants, the roots of the seedlings are encouraged to extend into the moist deep sand layer, thereby enhancing the wind resistance of the seedlings.

[0028] The device is used as follows: Figure 7 As shown, the operator rotates the torsion ring 302, which drives the retaining sleeve 301 to rotate synchronously. Since the retaining sleeve 301 is threadedly connected to the outer toothed sleeve 7, the retaining sleeve 301 will move upward along the outer toothed sleeve 7. After moving upward, the retaining sleeve 301 can wrap around the outside of the sapling trunk, forming a windproof and protective structure to prevent strong winds from blowing the sapling over. As the retaining sleeve 301 moves upward, the adapter ring 303 at the bottom of the retaining sleeve 301 moves upward simultaneously, thereby pulling the rope 8 upward. The rope 8 pulls the sieve plate 201 to rotate outward against the elastic force of the return spring. During the rotation of the sieve plate 201, the root growth path can be blocked. The gravel inside is pushed towards the ring plate 4, while the edge of the screen plate 201 at the end can prevent the gravel from slipping and improve the gravel removal effect. After the gravel is pushed to the bottom of the ring plate 4, it is gradually compacted under the pressure of the ring plate 4 to form a gravel layer around the planting cylinder 1. This gravel layer can fix the surrounding sand layer and reduce the impact of sand blowing on the seedlings. At the same time, the gaps between the gravel can increase the rainwater infiltration speed and promote the rapid infiltration of rainwater into the root system. When the sand blows across the sand collecting plate 5, the sand particles in the sand will flow along the inclined surface of the sand collecting plate 5 to the root and stem part of the seedling, realizing the backfilling of sand and further fixing the root base of the seedling.

[0029] When it is necessary to reset the sieve plate 201, rotate the torsion ring 302 in the opposite direction, the retaining sleeve 301 moves downward, the tension of the rope 8 disappears, and the rebound force of the return spring will drive the sieve plate 201 back to the initial inverted cone shape. The above operation can be repeated according to the growth of the seedling roots to continuously remove gravel obstacles for root growth.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
