Description

Technical Field

[0001] This invention relates to a vegetation restoration device, belonging to the field of vegetation restoration technology. Background Technology

[0002] For deserts with arid and barren climates, rainfall is scarce throughout the year, and sandstorms are frequent, occurring in all four seasons. There are over 220 days of dust storms annually, including approximately 60 days of heavy dust storms. The overall characteristics are drought, high evaporation rates, abundant sunshine, and plentiful heat. Disasters such as strong winds, sandstorms, blowing dust, and other hazardous weather events are frequent, leading to severe sand damage. Water resources are scarce and unevenly distributed, severely restricting agricultural development. However, areas on the edge of deserts have long hours of sunshine and strong solar radiation, making them among the richest regions in solar energy resources and important areas for large-scale solar energy development and utilization in my country. Therefore, the combination of photovoltaic power generation and desertification control can not only realize the transformation from "desertification advancing and people retreating" to "people advancing and desertification retreating," but also serve as an effective way to achieve both sand prevention and control and scientific utilization. The surface-distributed solar panels can effectively provide shade and protection for the vegetation below them. The surface of the solar panels in the windy and sandy desert needs to be washed frequently, and the water from the washing can irrigate the vegetation planted under the photovoltaic panels. This desertification control model has gradually become one of the scientific and efficient desertification control measures that are in line with the realities of the sandy areas in the new era. It can form a virtuous cycle that takes into account both ecological protection and economic development, and can effectively restore the vegetation of the photovoltaic power plant.

[0003] However, there are still some shortcomings in the restoration of vegetation in photovoltaic power plants: Firstly, it requires manual digging of holes in the sand for planting, and manual replenishment of water or nutrient solution to each plant in each hole, which is inefficient and labor-intensive; secondly, the solution tanks containing fertilizer and nutrient solution are difficult to move, and the solution in the tanks is prone to sedimentation during irrigation, resulting in uneven concentration of nutrient solution applied to the plants, which can easily lead to the death of plants due to insufficient or excessive nutrient solution.

[0050] The beneficial effects that this invention can produce include:

[0051] The vegetation restoration device provided by the present invention uses a solution tank, a lifting module, a mixing and pressurizing module, and a drilling and injection module installed on a mobile support. The lowering process of the lifting module drives the mixing and pressurizing module to stir the solution in the solution tank, and the drilling and injection module to drill holes in the ground. The rising process of the lifting module drives the mixing and pressurizing module to squeeze the solution in the solution tank, so that the solution is introduced into the drill holes through the drilling and injection module, thereby realizing automatic drilling and automatic irrigation.

[0052] The vegetation restoration device provided by this invention has several drilling and injection modules installed on a lifting frame, and several second transmission units that cooperate with the drilling and injection modules installed at the front end of a movable support. During the downward movement of the lifting frame driven by the electro-hydraulic push rod, the lifting frame can drive the Z-shaped seat to slide down, thereby driving the linkage gear, the first bevel gear, the second bevel gear, the drill rod, and the spiral blade to slide down. The drill rod and the second bevel gear slide down along the outer wall of the connecting pipe. During the downward movement of the linkage gear, it can rotate under the action of the third rack, thereby driving the first bevel gear to rotate. This, in turn, drives the drill rod and the spiral blade to rotate via the second bevel gear. By drilling holes in the sandy soil through the downward-moving and rotating drill rod and spiral blade, multiple holes can be drilled simultaneously in the sandy soil, greatly improving work efficiency and reducing labor intensity.

[0053] The vegetation restoration device provided by this invention, by setting a mixing and pressurizing module between the lifting frame and the solution tank, allows the drilling and injection module to move up and down to drill holes in the sand. Simultaneously, under the action of the lifting frame, second rack, transmission gear, and first rack, a lifting plate can slide up and down within the solution tank via a connecting rod. This allows the solution stored inside the tank to pass through the through-hole, thus mixing and preventing sedimentation. As the lifting plate continues to move downwards, a baffle blocks the through-hole, squeezing the solution at the bottom of the tank into the connecting pipe. The solution is then transported to the through-groove inside the drill rod. Under water pressure, the sealing ball overcomes the spring force of the connecting spring and moves away from the bottom of the drill rod, allowing the solution inside the through-groove to drain through the lower port into the sand holes drilled by the drilling and injection module. This achieves automatic multi-position drilling while simultaneously mixing and irrigating the drilled holes, demonstrating high practical value. Attached Figure Description

[0095] Furthermore, the baffle structure includes:

[0096] Two horizontal bars 14 are threaded through two vertical shafts 13 on the same side; a return spring 12 is used to support the horizontal bars 14.

[0098] refer to Figure 1 , Figure 3 as well as Figure 4 As shown, a mixing and pressurizing module 2 is provided between the lifting frame 6 and the solution tank 1. Several drilling and injection modules 8 are provided on the lifting frame 7. During the process of lifting the lifting frame 6 by the electric hydraulic push rod 4, the mixing and pressurizing module 2 can shake the solution inside the solution tank 1 and can transport part of the solution inside the solution tank 1 to the drilling and injection modules 8.

[0099] Specifically, the first transmission unit in the mixing and pressurizing module 2 includes a second rack 24 fixed to one end of the lifting frame 6, a first rack 21 on the opposite side of the second rack 24, a transmission gear 23 meshing between the first rack 21 and the second rack 24, and fixed plates 22 fixed to the outer walls of the solution tank 1 on both sides of the transmission gear 23.

This causes the drill rod 86 and the second bevel gear 82 to slide down along the outer wall of the connecting pipe 81. During the downward movement of the linkage gear 84, it can rotate under the action of the third rack 91, thereby driving the first bevel gear 89 to rotate. This, in turn, drives the drill rod 86 and the spiral blade 87 to rotate through the second bevel gear 82. The downward and rotating drill rod 86 and spiral blade 87 drill holes in the sand. At this time, the sealing ball 851, under the pressure of the sand and the elastic force of the connecting spring 852, can seal the lower port of the through groove 88.

[0124] After drilling is completed, the electric hydraulic push rod 4 drives the lifting frame 6 to move upward. The lifting frame 6 drives the drilling injection module 8 to move upward through the lifting frame 7. During the upward movement of the drilling injection module 8, the solution at the bottom of the solution tank 1 will be squeezed and discharged into the connecting pipe 81. The solution is then transported through the connecting pipe 81 to the through groove 88 inside the drill rod 86. Under the action of water pressure, the sealing ball 851 overcomes the elastic force of the connecting spring 852 and moves away from the bottom of the drill rod 86, so that the solution inside the through groove 88 can be discharged into the sand hole drilled by the drilling injection module 8 through the lower port of the through groove 88.

[0125] Another embodiment of the present invention provides a vegetation restoration method using the vegetation restoration device described above, comprising the following steps:

[0126] S1. Before carrying out vegetation restoration work, first store the water, fertilizer or nutrient solution required for vegetation restoration in the solution tank 1 as needed, and push the mobile cart 3 to the sandy area where photovoltaic power plants are located.

[0127] S2. When carrying out vegetation restoration work in sandy areas, the electric hydraulic push rod 4 is activated. The electric hydraulic push rod 4 moves the lifting frame 6 up and down through its internal hydraulic rod. When the lifting frame 6 moves down, the lifting frame 7 slides down between the two upright plates 52. The lifting frame 7 drives the Z-shaped seat 83 to slide down, thereby driving the linkage gear 84, the first bevel gear 89, the second bevel gear 82, the drill rod 86, and the spiral blade 87 to slide down. This causes the drill rod 86 and the second bevel gear 82 to slide down along the outer wall of the connecting pipe 81. During the downward movement of the linkage gear 84, it can rotate under the action of the third rack 91, thereby driving the second bevel gear 82 to rotate. In turn, the first bevel gear 89 drives the drill rod 86 and the spiral blade 87 to rotate. The downward and rotating drill rod 86 and spiral blade 87 drill holes in the sandy area. At this time, the sealing ball 851 can seal the lower port of the through groove 88 under the pressure of the sandy area and the elastic force of the connecting spring 852.

[0128] Meanwhile, as the lifting frame 6 moves downward, it drives the second rack 24 to move downward. Under the action of the transmission gear 23, the first rack 21 moves upward, thereby driving the lifting plate 27 to slide upward in the inner cavity of the solution tank 1 through the L-shaped connecting rod 26. The solution stored inside the solution tank 1 passes through the through hole 28, thereby shaking and mixing the solution inside the solution tank 1 to prevent the solution from settling.

[0129] S3. After drilling is completed, the electric hydraulic push rod 4 drives the lifting frame 6 to move upward. The lifting frame 6 drives the drilling injection module 8 to move upward through the lifting frame 7. At the same time, the lifting frame 6 can drive the second rack 24 to move upward. Under the action of the transmission gear 23, the first rack 21 and the L-shaped connecting rod 26, it can drive the lifting plate 27 to move downward. The downward-moving lifting plate 27 can shake and mix the solution inside the solution tank 1. When the lifting plate 27 is about to contact the bottom of the inner cavity of the solution tank 1, the lifting plate 27 will fit with the baffle 15, thereby sealing the through hole 28 on the lifting plate 27. As the lifting plate 27 continues to move downward, the solution remaining at the bottom of the solution tank 1 is squeezed into the connecting pipe 81 and transported through the connecting pipe 81 to the through groove 88 inside the drill rod 86. Under the action of water pressure, the sealing ball 851 overcomes the elastic force of the connecting spring 852 and moves away from the bottom of the drill rod 86, so that the solution inside the through groove 88 can be discharged into the sand hole drilled by the drilling injection module 8 through the lower port of the through groove 88.

[0130] S4. Plant the pre-prepared vegetation in the sand holes after the solution has been applied, and then move the mobile trolley 3 to drill and irrigate the next sandy area.

[0131] This invention utilizes a solution tank 1, a lifting module, a mixing and pressurizing module 2, and a drilling and injection module 8 mounted on a mobile support. The descent of the lifting module causes the mixing and pressurizing module 2 to agitate the solution in the solution tank 1, while the drilling and injection module 8 drills holes in the ground. The ascent of the lifting module causes the mixing and pressurizing module 2 to compress the solution in the solution tank 1, allowing the solution to be introduced into the drilled holes through the drilling and injection module 8, thereby achieving automatic drilling and automatic irrigation.

Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
