Description

Technical Field

[0001] This invention relates to the field of Gobi ecological restoration technology, specifically to a Gobi sand-fixing and water-conserving ecological restoration system and method. Background Technology

[0002] The Gobi Desert is characterized by an arid climate, scarce rainfall, high evaporation rates, and infertile soil with extremely poor water retention capacity. Frequent wind and sand activity further erodes the surface soil, resulting in an extremely fragile ecosystem that severely restricts the region's sustainable ecological development. Currently, Gobi desert sand fixation and water conservation restoration often employs single sand fixation or water conservation methods, such as laying gravel for sand fixation or spraying water-retaining agents. However, these methods have several drawbacks: single gravel sand fixation only achieves surface sand fixation and cannot improve soil water retention capacity, making it difficult to maintain the sand fixation effect in the long term; single water conservation measures lack effective surface protection, and water-retaining agents are easily eroded and lost by wind and sand, resulting in short-lived water retention and difficulty in achieving a synergistic effect between sand fixation and water conservation.

[0003] In addition, most existing sand-fixing and water-retaining equipment is a fixed structure, which cannot adapt to the mobile operation needs of complex Gobi terrain and has low operation efficiency. During the transportation of sand-fixing raw materials, gravel agglomeration and blockage of the discharge port are easy to occur, affecting the uniformity of the spreading. During the preparation of water-retaining solution, the raw materials are not mixed evenly and are easy to clump, resulting in inconsistent water retention effect after spraying. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a Gobi Desert sand fixation and water conservation ecological restoration system and method, enabling synergistic operation of sand fixation and water conservation, improving restoration efficiency and quality, and adapting to the operational needs of complex Gobi terrain.

[0005] The technical solution of the present invention is as follows: a Gobi Desert sand fixation and water conservation ecological restoration system, comprising a mobile base and sand fixation components and water conservation components respectively disposed at the front and rear ends of the upper end of the mobile base; a tracked walking mechanism is provided on the ground under the mobile base; The sand-fixing component includes a gravel storage bin located at the front of the upper end of the mobile base, and a collection trough and a conveying component arranged sequentially from top to bottom inside the gravel storage bin. A feeding hopper is provided at the top of the gravel storage bin, and a discharge hole is provided through the front end of the outer wall of the gravel storage bin at a position corresponding to the position of the conveying component. A spreading plate is inclinedly provided at the front end of the gravel storage bin at a position corresponding to the position of the discharge hole. A dropping trough is provided on the bottom end of the collection trough away from the discharge hole. The conveying component includes two conveying rollers that are rotatably engaged with the bottom of the gravel storage bin, a conveyor belt that is sleeved on the two conveying rollers, and a conveying motor provided on the outer wall of the gravel storage bin to power one of the conveying rollers. The water-retaining component includes a mixing tank located at the rear end of the upper surface of the mobile base, a pressure pump located on the upper surface of the mobile base and connected to the mixing tank, and a spray pipe located at the output end of the pressure pump; a material nozzle is connected to the end of the spray pipe; and a feeding cover plate is movably snapped onto the top of the mixing tank.

[0006] Furthermore, a cleaning assembly is provided at the front end of the mobile base; the cleaning assembly includes a mounting bracket sleeved on the outside of the material spreading plate and fixedly connected to the mobile base, a cleaning shovel movably hinged to the front end of the mounting bracket, and an electric adjusting rod movably hinged between the gravel storage bin and the cleaning shovel. Description: During the movement of the mobile base, the cleaning shovel can be used to clean up debris and clumps of soil on the Gobi Desert surface, providing a flat working surface for subsequent sand-fixing paving and water-retaining agent spraying; the tilt angle of the cleaning shovel can be adjusted by the electric adjustment rod, so that the cleaning component of this invention can be adapted to different surface cleaning needs.

[0007] Furthermore, the front end of the cleaning shovel has several cutting grooves evenly distributed; Note: The cutting groove can be used to cut and break up large clumps of soil on the Gobi Desert surface, improving the cleaning effect.

[0008] Furthermore, a vibrating screen plate is movably engaged at the upper part of the gravel storage bin; one end of the vibrating screen near the discharge port is movably hinged to the inner wall of the gravel storage bin; a rotating shaft is rotatably engaged inside the gravel storage bin and at the bottom of the other side of the vibrating screen plate, and a vibrating cam is provided on the rotating shaft that can abut against the ground under the vibrating screen plate; a rotating motor that provides power to the rotating shaft is provided on the outer wall of the vibrating screen plate. Description: A rotary motor drives a rotating shaft to rotate, which in turn drives a vibrating cam to rotate. The vibrating cam continuously pushes the vibrating screen plate, causing the vibrating screen plate to vibrate up and down around the hinge point, thereby achieving the screening and feeding of gravel and removing impurities from the gravel.

[0009] Furthermore, a top material rod is movably hinged to the bottom surface of the vibrating screen plate via a sliding seat, and the bottom end of the top material rod passes through the material drop chute; a retaining sleeve is movably sleeved on the inner wall of the gravel storage bin outside the top material rod; Explanation: When the vibrating screen plate vibrates up and down, it drives the top material rod to move up and down synchronously. The top material rod pushes the gravel in the drop chute to prevent the gravel from blocking the drop chute, so that the gravel can fall smoothly into the conveying component.

[0010] Furthermore, a swinging horizontal tube is movably connected to the top of the spray pipe via a rotary joint, and the material nozzle is located at the end of the swinging horizontal tube; a swinging rod is rotatably engaged with the outer wall of the mixing box via a rotating support, one end of the swinging rod is provided with a sector-shaped toothed disc, and the other end of the swinging rod is provided with a connecting sleeve fitted outside the swinging horizontal tube; a reciprocating motor is provided on the outer wall of the mixing box, and the output end of the reciprocating motor is connected to a drive gear that meshes with the sector-shaped toothed disc. Explanation: A reciprocating motor drives a drive gear to rotate. The meshing action of the drive gear and the sector gear causes the swing rod to rotate back and forth on the rotating support. This, in turn, causes the swing horizontal tube to swing back and forth around the rotating joint, realizing the reciprocating spraying of the material nozzle. This helps to expand the spraying range of the water-retaining agent and improve the uniformity of spraying.

[0011] Furthermore, a feeding assembly is provided at the top of the mixing chamber.

A conical hopper is connected to the bottom of the feeding box. A moving screw that is threadedly connected to the side wall of the feeding box is connected to the output end of the moving motor. Instructions: During use, the moving motor drives the moving screw to rotate. The connection between the moving screw and the feeding box causes the feeding box to move back and forth along the sliding rod, so that the modified plant fiber powder inside the feeding box is evenly distributed to various areas of the mixing box, which helps to improve the uniformity of mixing between the modified plant fiber powder and the solvent.

[0012] Furthermore, a mixing assembly is connected to the bottom of the feeding box; the mixing assembly includes support plates disposed on both sides of the bottom of the feeding box, a drive shaft rotatably engaged between the two support plates, and a stirring rod rotatably engaged between the two support plates and located below the drive shaft; the support plates are hollow inside; both ends of the drive shaft pass through the support plates at corresponding positions and are connected to drive gears; the inner sidewall of the mixing box is provided with toothed plates that mesh with the two drive gears respectively; both ends of the drive shaft are provided with first sprockets located inside the support plates at corresponding positions; both ends of the stirring rod are provided with second sprockets located inside the support plates at corresponding positions; the first sprockets and second sprockets inside the same support plate are connected by chain drive.

The drive shaft drives the stirring rod to rotate through the cooperation of the first sprocket, chain and second sprocket, so as to realize the continuous stirring of the material in the mixing box and further improve the mixing effect of the material.

[0013] Furthermore, a filter plate is provided inside the mixing chamber and below the mixing components, and a scraper plate is provided between the two support plates to abut against the upper surface of the filter plate; Explanation: The filter plate can filter impurities in the mixed solution in the mixing tank, preventing them from clogging the material nozzles; when the feeding box moves, it can drive the scraper to move synchronously, using the scraper to clean impurities on the surface of the filter plate, preventing the filter plate from clogging and ensuring the filtration effect of the filter plate.

[0014] Furthermore, a compaction roller is rotatably engaged at the front end of the ground under the mobile base; Explanation: Compaction rollers can be used to compact the gravel layer on the ground surface, making the gravel adhere tightly to the ground surface and improving the sand fixation effect.

[0015] Furthermore, several material chutes are evenly distributed on the upper surface of the material paving plate; Explanation: The material chute guides the gravel discharged from the conveying components, ensuring it is evenly distributed on the ground surface, preventing gravel accumulation, and improving the uniformity of the sand-fixing material. This invention also provides a Gobi Desert sand fixation and water conservation ecological restoration method, based on the above-mentioned Gobi Desert sand fixation and water conservation ecological restoration system, comprising the following steps: S1. Add gravel raw materials to the gravel storage bin through the feeding hopper, and add water-retaining agent to the mixing box; S2. Drive the mobile base to the area to be repaired by the tracked walking mechanism; S3. Gravel raw materials fall onto the conveyor belt through the chute at the bottom of the collection trough. The conveyor motor drives the corresponding conveyor rollers to rotate, so that the conveyor belt discharges the screened gravel particles through the discharge hole. The gravel particles are evenly spread on the surface of the adjacent ground under the action of the spreading plate. S4. Start the pressure pump and use the pressure pump to deliver the water-retaining agent to the material nozzle through the spray pipe. Use the material nozzle to spray the water-retaining agent evenly on the surface of the gravel sand-fixing layer to achieve Gobi sand fixation and water retention ecological restoration.

[0016] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: First, the restoration system of the present invention has a reasonable structural design and can achieve the synergistic operation of sand fixation and water conservation on the Gobi surface: the sand fixation component forms a sand fixation layer by laying gravel to prevent wind and sand erosion, and the water conservation component sprays modified plant fiber water to improve the soil's water retention capacity. The synergistic effect of the two effectively improves the ecological restoration effect of the Gobi and solves the problem of the disconnect between sand fixation and water conservation in the existing technology. Secondly, the mobile base of the present invention is equipped with a tracked walking mechanism at the bottom, which effectively improves the system's flexibility and applicability. At the same time, the cleaning component, sand-fixing component, water-retaining component, and compaction component are integrated on the mobile base to realize the integrated operation of surface cleaning, gravel laying, water-retaining spraying, and compaction maintenance, further improving work efficiency. Third, the water-retaining component of the present invention improves the mixing uniformity of the water-retaining solution by adding a feeding component and a mixing component, avoids the clumping of modified plant fibers, prevents the spray pipe and nozzle from being blocked by setting a filter plate, and uses a swinging horizontal pipe to drive the material nozzle to spray back and forth, which helps to improve the spraying uniformity of the water-retaining agent and improve the water retention effect of the Gobi Desert.

[0028] Example 10 This embodiment describes a Gobi Desert sand fixation and water conservation ecological restoration method, based on a Gobi Desert sand fixation and water conservation ecological restoration system of Embodiment 9, including the following steps: S1. Gravel raw materials are added to the gravel storage bin 20 through the feeding hopper 200.
