Description

Technical Field

[0001] The invention relates to a technology for renovating abandoned mining areas, and in particular to a recycling device and a recycling method for a cutting protection device used for plant renovation of abandoned mining areas. Background Art

[0002] The transformation of abandoned mining areas has always been an important part of environmental protection projects. There are many technical routes for the transformation of abandoned mining areas. In practice, the combination of multiple technical routes and adapting to local conditions is the key to the ultimate success of the transformation. Among the many technical routes, the successful planting of suitable plants has always been the most core technical support. However, in traditional solutions, cutting planting technology is not widely used in the transformation of abandoned mining areas. The main reason is that there are many rocks in the mining area, and it is difficult to drill holes for cuttings. In addition, the subsequent scattered stones will also affect the normal growth of the cuttings and reduce the survival rate of the cuttings.

[0003] The inventors have found that the growth stage of cuttings plants before they take root and survive is easily affected by the scattered gravel in the mining area. After the cuttings plants take root and survive, even if some of the gravel grinds and scratches the cuttings plants, the cuttings plants can basically continue to grow, which has little effect on the final cutting survival rate and transformation effect.

[0004] Lateral protection is provided for the cutting plants by means of multiple protection rods extending into the cutting holes, top protection is provided by means of a pressure plate located around the top of the cutting holes, and at the same time, a limit is provided for the protection rods. Based on such a cutting protection device, the cutting plants can smoothly pass through the fragile new root germination stage and other cutting growth stages. However, in the subsequent growth stage of the cutting plants, the cutting protection device will also affect the further development of the cutting plants and need to be removed in time. Considering the relatively harsh growth environment of the cutting plants, the current environmental state needs to be destroyed as little as possible during the removal of the cutting protection device, and the cutting plants must not be damaged.

[0005] Based on this, the inventors have researched and designed a recycling device and a recycling method for a cutting protection device used for plant transformation in abandoned mining areas. The cutting protection device can be smoothly removed through the device and method, thereby ensuring the survival rate of the cuttings and improving the transformation effect of the abandoned mining areas.

[0073] The present invention also provides a method for recovering a cutting protection device used for plant transformation in abandoned mining areas, and the method is realized by the recovery equipment for the cutting protection device used for plant transformation in abandoned mining areas as described above.

[0074] Preferably, the method comprises the following steps:

[0075] Step 1, lift one side of the pressure plate 1 to a height of 3-5 cm;

[0076] Step 2, control the pressure plate 1 to fall back to the ground, and further lift the protective rod 2 which has been raised 3-5 cm to a height of 5-10 cm;

[0077] Step 3, pull out the raised protective rod 2;

[0079] Step 5, repeating steps 1 to 4 until all the protection bars 2 are pulled out and the holes of each protection bar 2 are backfilled with fertilizer and foreign soil;

[0080] Step 6, remove and recycle the pressure plate 1;

[0081] Step 7, place the pressure plate 1 and the protection bar 2 on the transport vehicle 5.

[0082] Preferably, in step 1 , the jaws 33 are extended into the lifting grooves 11 of the pressure plate 1 , the support platform 32 is placed on the ground, and then the pressure plate 1 is lifted by pressing the pressure rod 31 .

[0084] In the present application, the pressure plate 1 is lifted by the cooperation of the jaws 33 and the lifting groove 11, thereby lifting the protective rod 2, so that a gap appears between the protective rod 2 and the pressure plate 1, and the jaws 33 can be further extended between the end of the protective rod 2 and the pressure plate 1 to further lift the protective rod 2. When the protective rod 2 is lifted to a sufficient height, the protective rod can be conveniently grasped and then pulled out. Such an operation process can basically ensure the smoothness of the protective rod pulling out and recovering process, and the overall pulling out process is basically carried out in the vertical direction, which can not only preserve the integrity of the protective rod hole to the greatest extent, but also reduce the damage to the cutting plants and the surrounding environment during the pulling out of the protective rod, thereby improving the survival rate of cuttings in abandoned mining areas.

[0085] In a preferred embodiment, in step 4, a rod-shaped structure having an outer diameter slightly smaller than that of the protective rod 2 is used to assist in backfilling fertilizer and foreign soil, and to compact the fertilizer and foreign soil. That is, the rod-shaped structure is inserted into the funnel-shaped main body to accelerate the sinking speed of the fertilizer and foreign soil in the main body. As the backfilling work continues, the funnel-shaped main body is gradually lifted upward. After the subsequent funnel-shaped main body is completely separated from the pressure plate, the rod-shaped structure is inserted into the through hole of the pressure plate to compact the fertilizer and foreign soil.

[0086] In a preferred embodiment, in step 6, the pressing plate 1 is rotated and bent outward to enlarge the notch on the pressing plate 1, and then the pressing plate 1 is taken out without touching the cutting plants.

[0087] Example

[0088] In the abandoned mining area being transformed, 1,000 cutting plants have passed the rooting and survival period, and the cutting protection devices at the cutting holes can be removed; the cutting protection devices are recycled by the recycling method of the cutting protection devices for plant transformation of abandoned mining areas, and the specific recycling method for each cutting protection device includes the following steps:

[0089] Step 1: Insert the jaws into the lifting groove on one side of the pressure plate, press the pressure rod to lift one side of the pressure plate to a height of 3-5 cm;

[0090] Step 2, withdraw the jaws, control the pressure plate to fall back to the ground, then extend the jaws between the end and the pressure plate, clamp the protective rod, and lift the protective rod that has been raised 3-5cm high to a height of 5-10cm;

[0091] Step 3: Pull out the raised protective rod by hand;

[0092] Step 4, insert the bottom end of the backfiller into the through hole of the pressure plate, and backfill the fertilizer and foreign soil into the hole of the protection rod through the backfiller, and tamp it;

[0093] Step 5, repeat steps 1 to 4 until all four guard bars are pulled out and the holes in each guard bar are backfilled with fertilizer and foreign soil;

[0094] Step 6, rotating and bending the pressing plate outward to enlarge the notch on the pressing plate, and taking out and recovering the pressing plate without touching the cutting plants;

[0095] Step 7, place the pressure plate and protection rod on the transport vehicle. Each transport vehicle can carry 50 sets of cutting protection devices. After being fully loaded, the cutting protection devices are transported to the centralized processing station. After the cutting protection devices are unloaded and fertilizers and foreign soil are added, the cutting protection devices are recycled.

[0096] A total of 10 people were mobilized to operate 10 sets of recovery equipment for cutting protection devices used for plant transformation in abandoned mines, and to implement the above-mentioned recovery method for cutting protection devices used for plant transformation in abandoned mines. It took a total of 8.2 hours to complete the recovery operation of all the cutting protection devices. On average, the recovery time for each cutting protection device was less than 5 minutes, which has high operating efficiency and can be applied on a large scale.

[0097] Further, 100 cuttings were randomly selected from the 1,000 cuttings, and their growth and development were tracked and observed over the following month. It was found that 98 of them grew smoothly and were not affected by the recovery operation of the cutting protection device. The 2 cuttings that failed to grow normally had poor growth due to too few roots.

[0098] It can be seen from the above embodiments that the method for recovering the cutting protection device for plant transformation in abandoned mining areas provided in the present application has high working efficiency and extremely high reliability.

[0099] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve only as an illustration. On this basis, the present invention may be subjected to a variety of substitutions and improvements, all of which fall within the scope of protection of the present invention.
