Description

Technical Field

[0001] This utility model relates to the field of desert vegetation restoration technology, and in particular to a plant bed that promotes the restoration of desert vegetation. Background Technology

[0002] Plant beds that promote vegetation restoration in sandy areas refer to specific soil structures and environmental conditions suitable for plant growth created through artificial intervention in sandy environments. They aim to provide a good foundation for the restoration and growth of vegetation in sandy areas. This requires a series of improvement and treatment measures for sandy areas, such as adding organic matter, improving soil structure, and enhancing water and fertilizer retention capacity. These measures are intended to overcome the adverse factors of sandy soil infertility, poor water retention, and severe wind erosion, enabling plants to take root and grow successfully on the plant beds, thereby gradually achieving the restoration of vegetation and the improvement of the ecosystem in sandy areas.

[0003] A search revealed a Chinese patent publication number, CN204849725U, which discloses a tall fence-like sand barrier constructed using living Calligonum mongolicum plants. The barrier includes at least two parallel sand barrier strips, placed on the windward slope of gentle sandy land or dunes, and has a single-row or double-row structure. It is arranged in layers perpendicular to the prevailing wind direction. The material is living Calligonum mongolicum plants, which are shrubs with strong adaptability to arid sandy lands and excellent natural regeneration capabilities. The new utility model provides a novel prevention and control model that organically combines biological and mechanical protection effects through the layered construction of the living sand barrier of Calligonum mongolicum. It reduces wind speed layer by layer, deposits and intercepts drifting sand, thereby improving the limitations of traditional large-scale afforestation, such as high cost, high water consumption in sandy areas, rapid decline in protection function in the later stage, and difficulty in natural vegetation regeneration and restoration. It makes full use of the advantages of natural reproduction and regeneration of Calligonum mongolicum. Under the ideal biological protection model, it also has the function of high-rise fence sand barriers to efficiently intercept drifting sand, providing a way to control wind and sand erosion in arid and rain-scarce sandy environments. However, sandy land has poor water and fertilizer retention capacity, vegetation survival is difficult, and the effect of sand control is slow. Utility Model Content

[0025] As a further description of the above technical solution:

[0026] A fixing ring is installed at the top of the sandy ground, and the main pipe is located in the middle of the bottom wall of the fixing ring. Bolts are threaded to both the front and rear sides of the top wall of the fixing ring.

[0027] The above technical solution involves using a retaining ring to prevent the main pipeline from shaking due to water pressure or external forces, and bolts to secure the retaining ring to the sandy ground.

The gear ring then drives the gear plate to rotate. The gear ring meshes and pushes the plate to swing around the rotating shaft. The sliding column and the sliding groove cooperate to ensure stable movement. This adjusts the water output of the branch pipe or dripper, realizes precise irrigation on demand, and improves the water supply efficiency for the restoration of vegetation in sandy areas.

A main pipe 302 is installed on the bottom wall of the water storage tank 301. A connecting pipe 303 is fixedly connected to the left side of the top wall of the main pipe 302. A branch pipe 304 is installed at the end of the main pipe 302. Multiple drippers 305 are equidistantly installed on the front side of the outer wall of the branch pipe 304. A drive assembly 306 is installed on the top of the sandy ground 1. An adjustment assembly 307 is installed at the bottom of the drive assembly 306. The moving assembly 306 includes a rotating rod 3061, which is disposed at the top of the connecting pipe 303. A bevel gear 3062 is fixedly connected to the bottom wall of the rotating rod 3061. A bevel gear 3063 is meshed with the left side of the outer wall of the bevel gear 3062. The rotation of the rotating rod 3061 drives the bevel gear 3062, thereby causing the bevel gear 3063 to rotate. A connecting shaft 3064 is fixedly connected to the middle of the left side of the outer wall of the bevel gear 3063. A spur gear is fixedly connected to the end of the connecting shaft 3064.

[0042] Specifically, water flows in from the water storage tank 301 through the main pipe 302. The rotation of the rotating rod 3061 drives the first bevel gear 3062, which in turn causes the second bevel gear 3063 to rotate. The second bevel gear 3063 transmits power to the spur gear 3065 through the connecting shaft 3064, causing it to rotate. The rotation of the spur gear 3065 drives the gear ring 3071 to rotate.

The support structure of the inner wall of the connecting pipe 303 ensures that the rotating rod 3061 is axially fixed and avoids deviation during transmission. The spur gear 3065 is rotatably connected inside the main pipe 302. The spur gear 3065 inside the main pipe 302 can prevent sand and dust and external debris from entering and reduce wear. At the same time, the inner wall of the pipe supports the gear shaft, which enhances the stability of the transmission structure. The inner wall of the water storage tank 301 adopts an inverted cone design. The inverted cone inner wall can guide the water in the water storage tank 301 to converge towards the bottom center, ensuring that the water flow is stable when passing through the main pipe 302. It avoids uneven drip irrigation caused by water accumulation at the bottom of the tank or water flow dispersion. The main pipe 302 is connected to the middle of the bottom wall of the water storage tank 301. The main pipe 302 at the middle of the bottom wall ensures that the water flows out evenly from the lowest point of the water storage tank 301, avoiding water flow deviation or water accumulation in the tank caused by the offset outlet.

Rotating the rotating rod 3061 drives the first bevel gear 3062 to rotate, which in turn drives the second bevel gear 3063 to rotate. The second bevel gear 3063 drives the spur gear 3065 to rotate through the connecting shaft 3064. The spur gear 3065 drives the gear ring 3071 to rotate. The gear ring 3071 meshes with the composite plate 3072, pushing the composite plate 3072 to swing around the rotating shaft 3073.
