The stems of the green plants are connected to the multifunctional rod by the flexible rod, which plays a supporting role when the green plants are affected by wind. Even if the green plants sway back and forth due to the invasion of wind, the flexible characteristics of the flexible rod can be used to reduce the destructive force. The fixing effect of the green plants of the present invention is not only reflected underground, but also on the ground.

[0015] 2. Use the method of ground irrigation to fill the ballast tank with water, and use the water collection function of the ballast tank to make water penetrate through the second seepage hole on the lifting plate to the sponge, and use the water absorption performance of the sponge to temporarily store the water in the compression space. As the water in the sponge gradually becomes saturated, the excess water seeps into the functional cover, so that when the functional cover is buried, the covered sand is moisturized, thereby replenishing the water to the roots of the green plants. It is worth noting that the sponge collects and temporarily stores water and is used to keep the sand in the functional cover moist for a long time, avoiding the roots from absorbing the water too early and extending the use time of the water. After the water in the ballast tank is completely dried up, watering can be carried out again. The actions of the flexible rod, multifunctional rod, sponge and lifting plate not only have a buffering effect on the above-ground stems of the green plants, but also use the actions they generate to simultaneously replenish the water to the roots of the green plants.

DETAILED DESCRIPTION

[0021] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0022] In one embodiment, Figure 1-Figure 4 As shown: the present embodiment provides a planting device for restoration of desert vegetation, comprising a base sand 1, the top layer of the base sand 1 is covered with a moisture retaining layer 2, a counterweight cabin 3 is pressed on the top of the moisture retaining layer 2, the opening of the counterweight cabin 3 faces upward, a flow port 4 communicating with each other is arranged between the bottom of the counterweight cabin 3 and the moisture retaining layer 2, a functional cover 5 is arranged at the bottom of the flow port 4, the functional cover 5 is a mesh cover, the sand in the base sand 1 passes through the mesh holes into the functional cover 5, the functional cover 5 is a horn mask, the large port opening of the functional cover 5 faces downward and is buried in the base sand 1, the small port opening faces upward and is connected to the flow port 4 and communicates with the counterweight cabin 3 through the flow port 4, a guide sleeve 6 is installed in the middle of the functional cover 5, a partition 7 is fixed at three quarters of the guide sleeve 6, a stud 8 is fixed at the bottom end of the partition 7, an anchor rod 9 is arranged in the guide sleeve 6, a threaded hole is opened at the top of the anchor rod 9, and the top of the anchor rod 9 is screwed in The perforations are connected to the stud 8, the bottom end of the anchor rod 9 is anchored in the base sand 1, the guide sleeve 6 is filled with sponge 10, and a lifting plate 11 is slidably matched in the guide sleeve 6. The lifting plate 11 is located above the partition 7, and a compression space 12 whose size changes with the lifting action of the lifting plate 11 is formed between the lifting plate 11 and the partition 7. The sponge 10 is located in the compression space 12, and a first seepage hole 13 is opened between the periphery of the guide sleeve 6 and the functional cover 5, and a second seepage hole 14 is opened on the lifting plate 11. Water is stored in the counterweight cabin 3, and a multifunctional rod 15 that passes upward through the counterweight cabin 3 is fixed on the top surface of the lifting plate 11. Green plants 16 are planted in the base sand 1, and the roots of the green plants 16 are inserted into the functional cover 5 through the mesh. The stems of the green plants 16 are connected to the multifunctional rod 15 through the flexible rod 19, the bottom end of the functional cover 5 is closed, and the bottom surface of the functional cover 5 is close to the claw of the anchor rod 9.

[0023] Principle and technical effect: before planting, dig up the base sand 1, bury the functional cover 5 in the base sand 1, spread the moisture-retaining layer 2 on the top surface of the base sand 1, and bury the guide sleeve 6, partition 7, stud 8, anchor rod 9 and sponge 10 in the base sand 1 by the functional cover 5. The anchor rod 9 uses the claws and stud 8 to reinforce the functional cover 5 after it is deeply buried. The green plant 16 passes through the moisture-retaining layer 2 and is planted in the base sand 1. The root system of the green plant 16 will pass through the mesh holes and penetrate into the functional cover 5 and into the base sand 1 in the functional cover 5. The mesh holes of the functional cover 5 are used to fix the root system of the green plant 16. During actual planting, two sets of functional covers 5 and other components as well as a planting device for vegetation restoration composed of a counterweight cabin 3 are arranged on both sides of the same green plant 16. When the root system of the green plant 16 grows to both sides, it passes through the mesh holes and penetrates into the functional covers 5 on both sides. This can further firmly fix the green plants 16 in the base sand 1. Taking into account the weather influences such as sand and dust in the sand, a compression space 12 formed between the partition 7 and the lifting plate 11 is set in the guide sleeve 6, and the compression space 12 is filled with sponge 10. A multifunctional rod 15 is set on the top surface of the lifting plate 11, and the stem of the green plant 16 is connected to the multifunctional rod 15 through a flexible rod 19 (such as a rubber rod, a rubber sheet, and a rubber plate, etc.). The stem of the green plant 16 is connected to the multifunctional rod 15 by the flexible rod 19, which plays a supporting role when the green plant 16 is affected by wind. Even if the green plant 16 sways back and forth due to the invasion of wind, the flexible characteristics of the flexible rod 19 can be used to reduce the destructive force. The fixing effect of the green plant 16 of the present invention is not only reflected underground, but also above ground.

[0024] In accordance with the above, especially when the green plant 16 swings toward one side of the multifunctional rod 15, in addition to utilizing the flexibility of the flexible rod 19 to reduce the destructive force, the flexible rod 19 also utilizes the downward bending shape to produce a downward bending deformation, and utilizes the bending force to push the multifunctional rod 15 downward, and the multifunctional rod 15 pushes the lifting plate 11 to descend, and the lifting plate 11 squeezes the sponge 10, so that the sponge 10 is compressed in the compression space 12, thereby buffering the destructive force.

[0025] In addition, the bottom surface of the counterweight cabin 3 falls on the moisture retaining layer 2, compacting the moisture retaining layer 2 on the base sand 1 to prevent the moisture retaining layer 2 from being damaged.

[0026] In addition, water is poured into the ballast compartment 3 by means of ground irrigation, and the water collection function of the ballast compartment 3 is utilized to make the water penetrate through the second liquid seepage hole 14 on the lifting plate 11 to the sponge 10, and the water absorption performance of the sponge 10 is utilized to temporarily store the water in the compression space 12. As the water in the sponge 10 is gradually saturated, the excess water penetrates through the second liquid seepage hole 14 on the lifting plate 11 to the sponge 10. Figure 2The first seepage hole 13 shown seeps into the functional cover 5, so that when the functional cover 5 is buried, the covered sand is moisturized, thereby replenishing water for the roots of the green plants 16. It is worth noting that the sponge 10 collects and temporarily stores water and is used to keep the sand in the functional cover 5 moisturized for a long time, thereby preventing the roots from absorbing the water too early and extending the use time of the water. After the water in the counterweight compartment 3 is completely dried up, watering can be carried out.

[0027] As mentioned above, when the green plant 16 is attacked by strong wind, the flexible rod 19 bends downward and pushes the multifunctional rod 15 down, and the multifunctional rod 15 pushes the lifting plate 11 to go down and squeeze the sponge 10, so that the sponge 10 is compressed and buffered in the compression space 12, and at the same time, the water in the sponge 10 is squeezed and discharged, thereby achieving the purpose of automatic water infiltration and replenishment from the first seepage hole 13 to the functional cover 5. It can be seen that the actions of the flexible rod 19, the multifunctional rod 15, the sponge 10 and the lifting plate 11 not only have a buffering effect on the above-ground stems of the green plant 16, but also use the actions they produce to synchronously replenish water to the roots of the green plant 16.

[0028] The moisturizing layer 2 is a moisturizing film or a film group composed of multiple moisturizing films, which prolongs the use time of moisture in the sand and improves the moisturizing effect.

[0029] like Figure 1 As shown, a third seepage hole 17 is provided at the bottom of the ballast tank 3, and the bottom end of the third seepage hole 17 is communicated with the top surface of the moisturizing layer 2. After the water is stored in the ballast tank 3, in addition to most of the water flowing into the functional cover 5 through the flow port 4, part of the water directly passes through the third seepage hole 17 and acts on the moisturizing layer 2, so that the moisturizing effect of the moisturizing layer 2 is better, especially when the root system grows toward the upper area of ​​the functional cover 5, it can also play a certain moisturizing role for this part of the root system.

[0030] like Figure 1 As shown, in order to improve the rationality of the structure, the bottom of the counterweight cabin 3 gradually tilts downward toward the flow port 4, which is convenient for pouring water into the sponge 10. The top of the flow port 4 is provided with an arc surface 18 opposite to the lifting plate 11. The size of the arc surface 18 in the width direction is smaller than the diameter of the lifting plate 11, which can prevent the lifting plate 11 from separating from the guide sleeve 6.

[0031] In another embodiment, if Figure 1 , Figure 4As shown, a first hinge shaft 20 is provided at one end of the flexible rod 19, a second hinge shaft 21 is provided at the other end of the flexible rod 19, a cotton sleeve 22 is connected to the stem of the green plant 16, a hinge seat 26 is provided at the top of the multifunctional rod 15, a swing rod 27 that swings flexibly toward the green plant 16 is connected to the top of the hinge seat 26, a buckle sleeve 23 is connected to the swing rod 27, a first connecting plate 24 is provided on the cotton sleeve 22, a second connecting plate 25 is provided on the buckle sleeve 23, a connecting hole is provided on the first connecting plate 24, a connecting hole is also provided on the second connecting plate 25, and the second hinge shaft 20 is connected to the first connecting plate 24. The shaft 21 is transferred to the second connecting plate 25, and the rocker arm 27 and the hinge seat 26 on the top of the multifunctional rod 15 are transferred through a pin shaft 28. A torsion spring 29 is connected to the pin shaft 28. One free end of the torsion spring 29 is upwardly restricted to the rocker arm 27, and the other free end of the torsion spring 29 is downwardly connected to the multifunctional rod 15. The two free ends of the pin shaft 28 are on the same side as the flexible rod 19. A baffle 30 is backed on the other side of the rocker arm 27 that is opposite to the flexible rod 19. The other end of the baffle 30 is fixed downwardly on the multifunctional rod 15. The baffle 30 is a spring plate. The flexibility of the flexible rod 19 is higher than the elasticity of the baffle 30.

[0032] In this embodiment, due to the uncertainty of wind direction, when the flexible rod 19 swings toward the green plant 16, it will use Figure 1 The right end shown in the figure drags the buckle sleeve 23 to the left, and the buckle sleeve 23 drags the swing rod 27 to swing leftward around the pin 28, thereby reducing the destructive force of the wind. The torsion spring 29 limits the swing angle of the swing rod 27 to prevent the swing rod 27 from deflecting too seriously, causing the flexible rod 19 to lose the protective effect on the green plant 16. When the flexible rod 19 swings toward the direction of the multifunctional rod 15 due to the uncertainty of the wind direction, the flexible rod 19 will use the right end to push the buckle sleeve 23, and the buckle sleeve 23 will push the swing rod 27 to the right, but the right side of the swing rod 27 is blocked. The sheet 30 is limited, so the swing rod 27 does not move. In order to relieve the pressure, the flexible rod 19 will bend downward, and use the right end to push the buckle sleeve 23, which drives the swing rod 27, so that the right force is transformed into a downward stress acting on the multifunctional rod 15, forcing the multifunctional rod 15 to push the lifting plate 11 down. First, the buffering effect generated by the compression of the squeezing sponge 10 is used to degrade the destructive force, and second, the squeezing effect generated by the compression of the squeezing sponge 10 is used to automatically infiltrate the stored water into the functional cover 5 for sand moisture retention and reasonable absorption by the root system. The multifunctional rod 15 adopts a hinged structure and a flexible connection with the flexible rod 19, so that it is more sensitive to perform the above actions.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
