Description

Technical Field

[0001] The present invention relates to the technical field of the treatment of alpine desertified grasslands, and more particularly to a rapid desert control method for alpine sandy land by using shrub-grass sand barriers for edge locking and revegetation. Background Art

[0002] Worldwide, desertification is a serious environmental problem. The area of sandy land is constantly expanding, posing a huge threat to the ecosystem, agricultural production and human life. Due to its special climate and geographical conditions, it is more difficult to control alpine sandy land. In alpine regions, the temperature is usually low, the temperature difference between day and night is large, the plant growth season is short, and the precipitation is scarce while the evaporation is large. After the soil is desertified, its water and fertilizer retention capacity is extremely poor.

[0003] In the prior art, desert control workers set up straw checkerboards and then plant plants with relatively developed root systems such as saplings in the checkerboards to achieve wind prevention and sand fixation operations on the sandy land. However, when planting saplings, workers need to first lay the straw checkerboards and then clean the weeds and foreign objects in the checkerboards to provide a better ecological environment for the survival of the saplings. The whole process is complex and time-consuming, which is not convenient for large-scale planting operations. Moreover, due to the fluidity of the gravel, it is difficult to fix the surrounding gravel after the planting holes are drilled, and the drilled planting holes will be submerged by the gravel again, making it difficult to plant the roots of the saplings deep into the sandy land, reducing the survival rate of the saplings. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid desert control method for alpine sandy land by using shrub-grass sand barriers for edge locking and revegetation to solve the problems existing in the above background art.

By driving the harrow teeth to clean the foreign matters in the sand through the rotation of the drill pipe, land preparation is realized. By driving the grass pressing wheel into the sand when the drill pipe descends, and by driving the grass pressing wheel to rotate through the rotation of the drill pipe, the wheat straw is pressed into the sand, eliminating the need for step-by-step operations, reducing labor and time costs, and greatly improving the planting efficiency.

[0029] 3. With the coordinated transmission of multiple motors, synchronous belt wheels and synchronous belts, the present invention can accurately move the hollow cylinder above the planting hole and insert the protective cylinder. Thus, when the hollow cylinder descends, through the clamping design of the second trapezoidal block and the protective cylinder, it is not only convenient for the sapling to accurately fall into the planting hole, but also after planting, the protective cylinder can be taken out of the sand through the clamping of the second trapezoidal block and the card slot, completing an efficient planting process.

[0051] Among them, the steep slope quicksand area is a steep slope terrain area with a windward slope greater than 25 degrees. Soil square bricks are laid vertically and closely in this area, with a horizontal interval of 10 cm between the soil square bricks. The surface of the soil square bricks is reseeded with a grass seed ratio of annual early-maturing oats: perennial native forage = 2:5;

[0052] The gentle slope quicksand area is a gentle slope terrain area with a windward slope less than 25 degrees. In this area, soil square bricks in a 1m×1m or 2m×2m grid are used for sand fixation and edge locking, and sand barriers are set in a row with an interval of 2 to 4 meters. The inside of the grid-shaped soil square bricks is reseeded with a grass seed ratio of annual early-maturing oats: perennial native forage = 1:1, with a depth of 5 cm. Alpine willows are planted in the center of the grid-shaped soil square bricks, and shrubs and grasses are densely planted for edge locking;

[0053] The flat sediment deposition area is a flat area. In this area, naked oats are sown into a 1m×1m grid biological sand barrier, and the inside of the grid is reseeded with a grass seed ratio of annual early-maturing oats: perennial native forage = 3:2, and artificial black soil is covered after sowing.

[0054] Specifically, for the steep slope quicksand area: in the severely wind-eroded section on the windward side, in the steep slope terrain area with a slope greater than 25 degrees, soil bricks (solidified artificial black soil) are laid vertically and tightly, with a horizontal interval of 10 cm. Oat sand barriers are sown in the gaps, with a depth of 5 cm and a seeding rate of 25 kg / mu. The surface of the bricks is reseeded with a grass seed ratio of annual:perennial = 2:5. For the gentle slope quicksand area: grid-shaped soil bricks (solidified artificial black soil) such as 1m×1m and 2m×2m are used for sand fixation and edge locking. Detached sand barriers are set at intervals of 2 to 4 meters according to the degree of desertification. The squares are reseeded with a grass seed ratio of annual:perennial = 1:1, with a depth of 5 cm. Alpine willows are planted in the center of the squares, and shrubs and grasses are densely planted for edge locking. For the flat sediment area of sediment-laden sand: Skin oats are sown into a 1m×1m grid biological sand barrier, and the squares are reseeded with a grass seed ratio of annual:perennial = 3:2. After sowing, it is covered with artificial black soil. For additional fertilization and reseeding in other areas: In other positions outside the core area of the demonstration site restoration, appropriate reseeding and sowing of grass seeds are carried out according to their different degradation degrees, and the reseeding area is 55,000 square meters. The highly adaptable grass seeds sown are 300 kg of oats (Qinghai 444 + Qingyin No. 1), 200 kg of Elymus dahuricus, and 100 kg of Poa annua. The three grass seeds are mixed in a ratio of 3:2:1. The annual oat grass seeds are sown at a rate of 15 kg / mu, and the mixed sown grass seeds are sown at a rate of 10 kg / mu. Based on the above steps, a sand blocking fence and high vertical sand barriers are formed to block the forward movement of wind and sand, and the enclosed area can quickly turn green.

[0055] Specifically, according to the configuration of selected suitable Elymus dahuricus, Elymus sibiricus, Festuca sinensis, Poa annua, and native grass species of Kengyilia, and early maturing oat varieties resistant to barrenness such as Qingyan series, Qingyin series, and Qinghai 444, and shrubs such as Salix paraplesia, Abies recurvata, Pinus sylvestris var. mongolica, Cupressus chengiana, and Piptanthus concolor; a windbreak belt is arranged at the upwind position of the desertified grassland. In cooperation with the planting of willows, the willow seedlings form squares of 150cm×150cm, and cattle and sheep manure is supplied, and root-fixing water prepared by mixing fungicides and auxins is supplemented.

[0056] The planting device includes a base 1 and a plurality of traveling wheels 2. A plurality of the traveling wheels 2 are all arranged at the bottom of the base 1. Specifically, the plurality of traveling wheels 2 are all of the prior art, and their specific installation methods and working principles will not be elaborated here. A control box 5 and a storage box 8 are arranged on the top of the base 1. A sliding hole is formed in the top of the base 1, and a sliding plate 9 is slidably installed in the sliding hole. A drilling mechanism is arranged on the sliding plate 9. The drilling mechanism includes a drill rod 16. A circular hole is formed in the top of the sliding plate 9, and the drill rod 16 is slidably installed in the circular hole. A protective cylinder 33 is clamped and installed on the circumferential outer wall of the drill rod 16. The bottom end of the protective cylinder 33 is designed with an inclined surface. The bottom end of the drill rod 16 is fixedly connected with a drill bit 3. The maximum diameter of the drill bit 3 is the same as the inner diameter of the protective cylinder 33. A rotating plate 4 is fixedly sleeved on the circumferential outer wall of the drill rod 16. A soil preparation component is arranged at the bottom of the rotating plate 4. A grass pressing wheel 28 is rotatably installed on the side of the rotating plate 4. An automatic rotation component is arranged on the drill rod 16. The automatic rotation component is used to drive the grass pressing wheel 28 to rotate when the drill rod 16 rotates. A through hole is formed in the top of the sliding plate 9, and a planting mechanism is slidably arranged in the through hole. The planting mechanism includes a hollow cylinder 7. The outer diameter of the hollow cylinder 7 is the same as the inner diameter of the protective cylinder 33.

[0057] As Figure 2 and Figure 3 shown, transmission grooves 11 are formed in the circumferential inner walls of the sliding holes. Two screw rods 10 are rotatably installed on the opposite inner walls of the transmission grooves 11. First synchronous belt wheels 12 are fixedly sleeved on the circumferential outer walls of the two screw rods 10. A first synchronous belt 13 is meshed and installed on the two first synchronous belt wheels 12. The sliding plate 9 is threadedly installed on the two screw rods 10. A motor groove is formed in the side inner wall of the transmission groove 11. A moving motor 14 is fixedly installed in the motor groove. Specifically, the moving motor 14 can be controlled by a PLC controller. The output shaft of the moving motor 14 is connected to the end of one of the screw rods 10. Through the arrangement of the two screw rods 10, the sliding plate 9 can be made to realize the horizontal movement function, thereby driving the drill rod 16 and the hollow cylinder 7 to move synchronously, realizing the position adjustment function, and facilitating a series of planting operations.

[0058] As Figure 4 and Figure 5As shown, the drilling mechanism further includes a U-shaped plate 6, which is fixedly installed on the top of the sliding plate 9. Lifting grooves are formed in the opposite inner walls of the U-shaped plate 6, and a rectangular cavity is formed in the U-shaped plate 6. The bottom inner walls of the two lifting grooves are both rotatably installed with lead screws 15. The tops of the two lead screws 15 both penetrate into the rectangular cavity and are fixedly sleeved with second synchronous belt pulleys 19. A second synchronous belt 18 is commonly engaged and installed on the two second synchronous belt pulleys 19. A lifting motor 20 is fixedly installed on the top of the U-shaped plate 6. Specifically, the lifting motor 20 can be controlled by a PLC controller. The output shaft of the lifting motor 20 is connected to the top of one of the lead screws 15.

A rotating motor 25 is fixedly installed on the top of the lifting plate 24. Specifically, the rotating motor 25 can be controlled by a PLC controller. The output shaft of the rotating motor 25 is connected to the top of the drill rod 16. By providing two lead screws 15, the lifting movement of the two lifting blocks 23 and the lifting plate 24 can be realized, so as to drive the drill rod 16 and the drill bit 3 to realize the lifting drilling function.

[0059] As Figure 9 and Figure 10 shown, the drilling mechanism further includes two arc-shaped blocks 34, both of which are fixedly installed on the circumferential outer wall of the drill rod 16.

An operation block 37 is slidably installed in the operation hole. The bottom of the operation block 37 is fixedly connected to the top of the first trapezoidal clamping block 35. A clamping groove 36 is formed in the circumferential inner wall of the protective cylinder 33. The first trapezoidal clamping block 35 is adapted to the clamping groove 36. By providing two first trapezoidal clamping blocks 35, it can be realized that after the two first trapezoidal clamping blocks 35 are clamped with the two clamping grooves 36, the movement of the drill rod 16 can drive the protective cylinder 33 to move synchronously, so as to insert the protective cylinder 33 into the planting hole to facilitate the protection of the surrounding gravel. And when the drill rod 16 is in the reset process, since the inclined surface of the first trapezoidal clamping block 35 faces upward, it will slide into the chute under the extrusion effect when it moves upward, so as to release the clamping effect between the two first trapezoidal clamping blocks 35 and the two clamping grooves 36, avoiding the drill rod 16 driving the protective cylinder 33 to move synchronously when moving upward, without the need for staff intervention, and providing a better planting environment for the subsequent saplings.

[0060] Specifically, when it is necessary to disassemble and overhaul the protective cylinder 33 after use, the two operating blocks 37 can be moved towards each other, which can drive the two first trapezoidal clamping blocks 35 to move synchronously towards each other, so that the first trapezoidal clamping block 35 is disengaged from the clamping groove 36, thereby realizing the disassembly function.

By arranging a plurality of rake teeth 27 at the bottom of the rotating plate 4, when the rake teeth 27 are inserted into the sand and rotated, weeds, garbage and other foreign matters in the sand can be cleaned. And when a plurality of rake teeth 27 rise, weeds and foreign matters can be left on the rake teeth 27, and gravel flows out from the gaps between the rake teeth 27, thereby realizing the land preparation operation of the planting area and eliminating the need for a cleaning step before planting, which simplifies the planting steps.

A rotating ring 22 is rotatably installed in the rotating groove. A connecting plate 17 is fixedly installed on the outer wall of the circumferential side of the rotating ring 22. A telescopic rod 29 is fixedly installed at the bottom of the connecting plate 17. The bottom end of the telescopic rod 29 is fixedly connected to the top of the rotating plate 4. A mounting shaft 32 is fixedly installed on the side of the rotating plate 4. The grass pressing wheel 28 is rotatably sleeved on the outer wall of the circumferential side of the mounting shaft 32. Through the arrangement of the rotating ring 22, the connecting plate 17 and the telescopic rod 29, the rotating plate 4 and the grass pressing wheel 28 can be supported and guided. And through the rotation of the drill rod 16, the grass pressing wheel 28 can be driven to rotate synchronously around the axis, so that the grass pressing wheel 28 realizes the rotation function and presses the wheat straw into the sand to achieve the function of wind prevention and sand fixation.

The straight rack 40 is fixedly installed on the inner wall of the side of the other limiting groove. A square plate 43 is fixedly installed on the top of the sliding plate 9. The driving motor 42 is fixedly installed on the side of the square plate 43. Specifically, the driving motor 42 can be controlled by a PLC controller. The output shaft of the driving motor 42 penetrates through the square plate 43 and is fixedly sleeved with a lifting gear 44. The lifting gear 44 is meshed with the straight rack 40. Through the meshing effect of the lifting gear 44 and the straight rack 40, when the lifting gear 44 rotates, the hollow cylinder 7 can be driven to lift. And through the arrangement of the limiting block 41, the phenomenon that the hollow cylinder 7 tilts can be effectively avoided.

[0064] As Figure 12 shown in the figure, the connecting component includes two second trapezoidal blocks 26. Two contraction grooves are formed in the outer wall of the circumferential side of the hollow cylinder 7. The inner walls of the sides of the two contraction grooves are both fixedly installed with second limiting shafts 30. The two second trapezoidal blocks 26 are respectively slidably installed on the outer walls of the circumferential sides of the two second limiting shafts 30. Second compression springs 31 are sleeved on the outer walls of the circumferential sides of the two second limiting shafts 30. Through the arrangement of the two second trapezoidal blocks 26, through the clamping effect of the second trapezoidal blocks 26 and the clamping grooves 36, when the hollow cylinder 7 moves upward, the protective cylinder 33 can be driven to move upward synchronously, so as to take out the protective cylinder 33 from the planting hole. And through the hollow setting between the hollow cylinder 7 and the protective cylinder 33, the sapling can be inserted into the planting hole from the middle position to realize the planting operation. Specifically, the installation directions of the two second trapezoidal blocks 26 and the two first trapezoidal blocks 35 are opposite. The inclined surfaces of the two first trapezoidal blocks 35 are upward, and the inclined surfaces of the two second trapezoidal blocks 26 are downward, so as to facilitate the realization of different functions.

[0065] The working principle and usage process of the planting device of the present invention:

[0066] During use, first, materials such as wheat straw are laid circularly on the sandy land. Then, the device is moved above the laid wheat straw materials. The protective cylinder 33 is sleeved from the bottom end of the drill rod 16 to the outside of the drill rod 16. Move the two operating blocks 37 towards each other, so that the protective cylinder 33 will not get stuck when moving upward. When the two first trapezoidal clamping blocks 35 and the two clamping grooves 36 are at the same horizontal position, release the limit on the two operating blocks 37, so that the two first trapezoidal clamping blocks 35 can achieve the reset function under the elastic action of the two first compression springs 39, thus enabling the protective cylinder 33 and the drill rod 16 to achieve the clamping function. Then, start the lifting motor 20 to drive one of the lead screws 15 to rotate. Thus, under the meshing action of the two second synchronous belt wheels 19 and the second synchronous belt 18, drive the other lead screw 15 to rotate synchronously. When the two lead screws 15 rotate, drive the two lifting blocks 23 and the lifting plate 24 to move downward synchronously through the thread action, so that the drill rod 16, the drill bit 3, and the protective cylinder 33 move downward synchronously. When the drill bit 3 contacts the sandy land, drive the drill rod 16, the drill bit 3, and the protective cylinder 33 to rotate synchronously through the rotation motor 25, so as to drill planting holes in the sandy land. The protective cylinder 33 supports the inner wall of the circumferential side of the planting hole, which can prevent quicksand from flowing into the planting hole and avoid submerging the planting hole, interfering with subsequent planting operations.

[0067] When the drill rod 16 rotates, it can drive the rotating plate 4 to rotate synchronously, thus driving the multiple rake teeth 27 at the bottom of the rotating plate 4 to rotate synchronously, and penetrate into the sandy land to clean weeds, garbage, etc. in the sandy land. Since the rake teeth 27 are generally L-shaped and the ends are inclined upward, the weeds and garbage can be filtered on the rake teeth 27, thus realizing the function of land preparation for the sandy land, without the need for workers to remove foreign objects on the sandy land, improving the planting efficiency.

[0068] When the drill rod 16 moves downward, it drives the rotating plate 4 and the grass pressing wheel 28 to move downward synchronously, so that the grass pressing wheel 28 presses the wheat straw into the sandy land. When the rotating plate 4 rotates around the axis of the drill rod 16, it can drive the grass pressing wheel 28 to move synchronously, so that the grass pressing wheel 28 rotates self - synchronously when revolving around the drill rod 16, and can press all the wheat straw into the sandy land, thus playing the role of wind prevention and sand fixation. With such a setting, the functions of land preparation and trampling and shaping can be realized during the planting process, without the need for step - by - step operations, improving the planting efficiency.

[0069] After the drilling operation is completed, the lifting plate 24 drives the drill rod 16 and the drill bit 3 to move upward. Since the inclined surfaces of the two first trapezoidal blocks 35 are upward, when the first trapezoidal blocks 35 move upward and are squeezed by the inner wall of the top of the card slot 36, the two first trapezoidal blocks 35 can move synchronously towards each other, releasing the connection with the protective cylinder 33, so that the protective cylinder 33 remains in the hole to achieve the support effect. And since the maximum diameter of the drill bit 3 is the same as the inner diameter of the protective cylinder 33, the drill bit 3 will not get stuck during the upward movement. With this setting, after the planting hole is drilled, due to the protection of the protective cylinder 33, quicksand will not enter the planting hole, preventing the planting hole from being submerged by quicksand and affecting the planting operation.

[0070] After the drill bit 3 is reset, by starting the moving motor 14 to drive one of the screws 10 to rotate, under the meshing action of the two first synchronous belt wheels 12 and the first synchronous belt 13, the other screw 10 is driven to rotate synchronously, so that the slide plate 9 moves horizontally under the action of the thread, driving the hollow cylinder 7 to move above the drilled planting hole and making the axis of the hollow cylinder 7 correspond to the axis of the protective cylinder 33. Start the driving motor 42 to drive the lifting gear 44 to rotate. Through the meshing action of the lifting gear 44 and the straight rack 40, drive the hollow cylinder 7 to move downward and insert it into the protective cylinder 33. Insert the sapling through the upper part of the hollow cylinder 7, so that it enters the planting hole through the hollow cylinder 7 and the protective cylinder 33. During the downward movement of the hollow cylinder 7, since the inclined surfaces of the two second trapezoidal blocks 26 are downward, they can move towards each other into the two contraction grooves under the extrusion of the protective cylinder 33. When the second trapezoidal block 26 moves to the position of the card slot 36, the elastic action of the second compression spring 31 realizes the clamping connection between the hollow cylinder 7 and the protective cylinder 33. Thus, when the hollow cylinder 7 is reset, the protective cylinder 33 is driven out of the planting hole, completing the process of planting the sapling.

[0071] Specifically, when the protective cylinder 33 needs to be disassembled later, the protective cylinder 33 can be pushed upward. When the protective cylinder 33 moves upward, since the inclined surface of the second trapezoidal block 26 is downward, through the extrusion of the inner wall of the bottom of the card slot 36 on the inclined surface of the second trapezoidal block 26, the two second trapezoidal blocks 26 can be driven to move synchronously towards each other, thus releasing the clamping connection between the two second trapezoidal blocks 26 and the two card slots 36. Then rotate the protective cylinder 33 by ninety degrees and move it downward to remove the protective cylinder 33 for the next use.

[0072] During the drilling and planting process, the staff can go to the next position to lay wheat straw. Thus, when the device is moved to this position, the drilling, soil preparation, and tamping and shaping operations can be directly carried out, greatly improving the planting efficiency.
