Description

Technical Field

[0001] The invention relates to the technical field of mine restoration, and in particular to a hydraulic seeding machine for carbon sink restoration in quarrying mines. Background Art

[0002] With the acceleration of industrial development, the demand for quarrying is large, and the environmental problems caused by mining are increasing day by day, causing damage to vegetation and soil, exposing the surface, collapse, and increasing the risk of geological disasters. In the process of mine restoration, it has a certain impact on the "carbon source" and "carbon sink" in the carbon cycle of terrestrial ecosystems. Through reasonable restoration measures, the damaged mine ecosystem will further improve its ability to reduce atmospheric CO 2 Therefore, the study of carbon effect of ecological restoration of abandoned land space of quarrying can maximize the win-win situation of "dual carbon" goals and land space ecological restoration tasks. How to use new ecological restoration ideas and technologies to restore and improve the ecological environment of abandoned mines while contributing to the "dual carbon" goals and further improve the efficiency of ecological restoration is a problem that needs to be considered at present.

[0003] At first, people used fiber soil to green the slopes, and later used horizontal grids, vegetation bag greening and imported soil grass planting technology to repair the slopes of abandoned mining areas. Finally, it developed into "spray-mix vegetation technology", which can not only restore the ecology, but also establish a self-maintaining carbon sink system. At present, the most commonly used vegetation substrate spraying technology in China is to combine geogrids, ecological rods, anchors, etc., and use a hydraulic sprayer to spray the vegetation substrate onto the slope according to the designed thickness. The vegetation substrate includes native soil or secondary soil, grass fiber, adhesive, water retaining agent, slow-release fertilizer, organic fertilizer, microorganisms, seeds, etc., which are mixed together and sprayed together under high pressure. Because the requirements for mixing of various substances are different, the requirements for the coverage level are also different, and the current hydraulic sprayers often cannot achieve targeted mixing and spraying, therefore, they need to be improved and optimized.

[0004] The utility model patent with patent publication number CN202587822U discloses a soil-injected hydraulic spraying machine, including a box body, an operating panel located on the upper surface of the box body, and a diesel engine, a mud pump, a gearbox and a tank body located inside the box body; a freely rotating nozzle is arranged above the box body, and the nozzle is connected to the mud pump through a pipeline; the mud pump is connected to the tank body. The soil-injected hydraulic spraying machine is not only suitable for the spraying and transportation of viscous materials, but also for the spraying of liquid materials, and has the characteristics of convenient construction, low cost, high safety and high efficiency. It can be widely used in slope greening, desert control, barren land improvement, lawn sowing, and spraying water and pesticides in orchards and forest gardens. However, for the high-demand quarrying and mine slope repair, layered spraying and classified mixing cannot be achieved, and the functionality is limited. Summary of the invention

[0028] (1) The hydraulic seeding machine for carbon sink restoration in quarrying mines of the present invention is aimed at the problem of destruction of exposed vegetation on the surface after mining. The traditional hydraulic seeding machine is optimized and improved so that it can be classified and stirred, and the vegetation substrate is sprayed out. The soil vegetation substrate is deeply stirred and crushed, and the auxiliary vegetation substrate (grass fiber, adhesive, water retaining agent, slow-release fertilizer, plant seeds) is gently stirred to improve the seed germination rate. In addition, two high and low spray pipes are used during spraying to achieve layered coverage, further improving the efficiency of spraying the vegetation substrate and the use effect, which is of great significance to the ecological restoration and carbon sink of mine slopes.

[0029] (2) The present invention is a hydraulic spraying machine for carbon sink restoration in quarrying mines. The two spray pipes can rotate slightly alternately during spraying, thereby expanding the spraying area. The most important thing is to keep the spraying uniform. As the driving component pushes the two spray pipes to move upward synchronously, the slope can be sprayed gradually from low to high. However, the amount and spraying angle of the two types of spraying vegetation substrates at high places and at ground locations are different. Therefore, while the two spray pipes move upward synchronously, the device also has the function of synchronously raising the first spray pipe, thereby achieving a uniform transition from the bottom of the slope to the top of the slope, and always keeping the two types of vegetation substrates in the spraying uniformly stacked, which greatly improves the work efficiency and the spraying effect of the vegetation substrate.

[0054] Example 3

[0055] The difference between this embodiment and embodiment 1 is that:

[0056] Three reinforcing rods 56 of the same length are evenly spaced on the outer circumference of the enhanced stirring rod 55, a grinding sheet 57 is provided at the end of the reinforcing rod 56, and a 5 mm gap is left between the grinding sheet 57 and the thickened layer 54. Nine flow stabilizing rods 65 of the same length are evenly spaced on the stabilizing stirring rod 64.

[0057] Working principle:

[0058] Next, we will explain in detail the working principle of the hydraulic seeding machine for carbon sink restoration in quarrying mines of the present invention.

[0059] When in use, firstly, ingredients need to be prepared, and the vegetation substrate is divided into two parts, one of which is a soil-based vegetation substrate that needs to be stirred and crushed. Native soil or secondary soil can be selected, and a portion of base fertilizer can be appropriately added thereto. After adding water, the mixture is mixed and stirred to reach a sprayable water content, and then injected into the first stirring tank 5. The first stirring motor 53 is turned on, and the strengthening rod 56 is driven by the strengthening stirring rod 55 to stir the soil mixture, and the grinding sheet 57 is contacted and squeezed with the inner wall of the thickening layer 54 to crush and grind it, so that the soil mixture is more uniform;

[0060] Then, the grass fiber, adhesive, water retaining agent, slow-release fertilizer, organic fertilizer, microorganisms, seeds and other vegetation substrates that need gentle stirring are mixed and added into the second stirring tank 6, and the second stirring motor 63 is turned on to drive the stabilizing stirring rod 64 to rotate, and the stirring and mixing are carried out by using a relatively low stirring speed under the action of the flow stabilizing rod 65;

[0061] Then, prepare to spray the vegetation substrate. Before spraying the vegetation substrate, it is necessary to adjust the positions of the first spray pipe 1 and the second spray pipe 2, park the hydraulic sprayer of the present invention carried by the transport vehicle near the slope, turn on the rotating motor 71 for fine adjustment, and the rotating motor drives the push rod motor 72 to rotate, so that the first spray pipe 1 and the second spray pipe 2 rotate around the rotating motor 71 under the action of the connecting block 9, so that the curved nozzles 8 on the first spray pipe 1 and the second spray pipe 2 are aligned with the bottom position of the slope, and after rotating to a suitable position, turn on the lifting motor 38 to drive the top plate 39 to move up and down, and the slider 36 slides inside the slide rail 37, so that the two clamping plates 35 are just located below the extension tube 11, and then turn on the gear motor 93 to drive the rotating gear 94 to rotate, so that the two driven gears 95 rotate synchronously, so that the first spray pipe 1 and the second spray pipe 2 rotate synchronously in opposite directions to the same direction and keep them parallel, and the preparation work is completed;

[0062] Start to spray the vegetation substrate, start the first spray pump 51 and the second spray pump 61, and transport the two different vegetation substrates to the first spray pipe 1 and the second spray pipe 2 through the first hose 52 and the second hose 62, and spray them to the bottom of the slope through the curved nozzle 8. Since the spraying amount of the two vegetation substrates is different, the spraying amount of the soil vegetation substrate is larger and is located in the lower layer, and the seed and grass fiber vegetation substrate requires less and is located in the upper layer, so the higher second spray pipe 2 sprays less and can cover the seed and grass fiber vegetation substrate on the upper layer;

[0063] While spraying, the gear motor 93 is continuously turned on to make it reciprocate, so that the first spray pipe 1 and the second spray pipe 2 can be driven to swing back and forth, and the limit ring 21 is continuously rotated in the rotation groove 92 to keep the first spray pipe 1 and the second spray pipe 2 stable, thereby expanding the spraying range and controlling the swing range within 30°;

[0064] After spraying at the bottom of the slope for a period of time, it is soon necessary to continue spraying upwards. At this time, the push rod motor 72 is turned on to drive the telescopic rod 73 to extend and push the first spray pipe 1 and the second spray pipe 2 upwards. At the same time, during the upward movement of the first spray pipe 1, the bottom of the extension pipe 11 contacts the top of the clamping plate 35 and begins to slide upward under the squeezing action of the clamping plate 35. The slide bar 13 slides in the slide groove 12, so that the extension pipe 11 and the curved nozzle 8 are continuously moved upward. The purpose of this setting is that when the slope position of the spraying is higher and the distance is farther, if the seeds and grass fiber planting substrate are to be covered on the upper layer of the soil planting substrate, it is necessary to increase the spacing between the first spray pipe 1 and the second spray pipe 2, and the extension pipe 11 achieves this purpose very well, and the slide bar 13 and the slide groove 12 can also remain sealed to prevent the planting substrate from leaking. At the same time, the extension pipe 11 should also be made of a material with a certain weight and its length should be guaranteed to avoid autonomous upward movement under hydraulic drive.

[0065] Experimental example

[0066] We repaired the slope of an actual quarrying mine using the hydraulic spraying machine of the present invention. The ecological environment in the area was severely damaged. The originally dense natural vegetation on the surface became a bare traumatic mountain with residual gravel. The quality of the surface soil was reduced, and various mining geological environmental problems gradually emerged. After planning and slope leveling, the estimated slope area to be treated was 2560m 2 By adopting geogrids, ecological rods, anchors, etc., and combining the use of the hydraulic sprayer of the present invention to spray the vegetation substrate onto the slope surface according to the designed thickness, the slope is ecologically restored. Since the separation effect of plant seeds and soil base fertilizer is better, the overall restoration effect is good, and the repaired mine is gradually restored to woodland and grassland.

[0067] We collected herbaceous plants after restoration and counted soil thickness, soil total carbon content, biomass per unit area, and total annual carbon sequestration (measured in CO 2 The results are shown in Table 1.

[0068] Table 1 Carbon sequestration in slope restoration

[0069]

[0070] It can be seen that after the hydraulic seeding machine of the present invention is used for spraying and repairing the vegetation substrate, the ecological recovery of the slope of the quarry is better. The growth of plants is the main factor in increasing carbon reserves. Compared with general hydraulic seeding machines, it is more efficient. If a general hydraulic seeding machine is expected to achieve the same effect, two devices are required to work at the same time and the working time is longer, which also increases diesel consumption and brings additional carbon emissions. Therefore, the hydraulic seeding machine of the present invention complies with the technical concept of reducing emissions and increasing carbon sinks, and realizes low-carbon emission restoration means to achieve a high-carbon sink ecosystem.
