Description

Technical Field

[0001] This invention relates to technology for the transformation of abandoned mining areas, specifically to a recycling device and method for a plant-based protective device for transforming abandoned mining areas. Background Technology

[0002] The transformation of abandoned mining areas has always been an important part of environmental protection projects. There are various technical approaches to the transformation of abandoned mining areas. In practice, combining multiple technical approaches and adapting to local conditions are the keys to the final success of the transformation. Among the many technical approaches, successfully planting suitable plants has always been the most core technical support. However, in the traditional approach, the cutting propagation technique is not widely used in the transformation of abandoned mining areas. The main reason is that mining areas are mostly rocky, making it difficult to drill holes for cuttings. Moreover, the subsequent loose stones will also affect the normal growth of the cuttings and reduce the survival rate of the cuttings.

[0003] The inventors have discovered that cuttings are easily affected by loose stones in mining areas during their growth stage before they take root and survive. Once the cuttings have taken root and survived, even if some of the loose stones grind and scratch the cuttings, they can still continue to grow, and this has little impact on the final survival rate and the overall improvement effect.

[0004] Multiple protective rods extending into the cutting hole provide lateral protection for the cutting, while a pressure plate located around the top of the cutting hole provides top protection and limits the movement of the protective rods. This cutting protection device allows the cutting to successfully pass through the fragile new root germination stage and other growth stages. However, in later growth stages, this cutting protection device can also affect the further development of the cutting and needs to be removed in time. Considering the harsh growing environment of the cutting, the removal of the cutting protection device should minimize disruption to the current environmental conditions and avoid damaging the cutting.

[0005] Based on this, the inventors have designed a recycling device and method for cutting protection devices used in the transformation of abandoned mining areas. The device and method can be used to successfully remove the cutting protection devices, ensuring the survival rate of the cuttings and improving the transformation effect of abandoned mining areas. Summary of the Invention

[0006] To overcome the above problems, the inventors conducted intensive research and designed a recycling device and method for a cutting protection device used in the transformation of abandoned mining areas. The cutting protection device includes multiple protective rods extending into the cutting holes and a pressure plate that provides limiting for them. The device includes a lifting device that can lift the pressure plate and the protective rods, and a backfilling device that backfills fertilizer and topsoil into the holes of the protective rods after they are pulled out. In order to facilitate transportation and improve recycling efficiency, a transport vehicle is also included to facilitate the rapid, efficient and safe recycling of the cutting protection device, thus completing the present invention.

[0007] Specifically, the purpose of this invention is to provide a recycling device for a cutting protection device used in the modification of abandoned mining areas by plants, wherein the cutting protection device includes a pressure plate 1 and a protective rod 2;

[0008] The pressure plate 1 is an arc-shaped structure with one end open, and it is attached to the ground around the insertion hole.

[0009] The protective rod 2 passes downward through the through hole on the pressure plate 1 and extends into the soil at the bottom of the cutting hole along the inner wall of the cutting hole. Multiple protective rods 2 are evenly distributed around the cutting plant.

[0010] The recycling equipment includes a lifting device 3, a backfiller 4, and a transport vehicle 5;

[0011] The lifting device 3 lifts the pressure plate 1 and the protective rod 2 to facilitate the removal of the protective rod 2. After all the protective rods 2 penetrating the pressure plate 1 are removed, the pressure plate 1 can be recycled.

[0012] Fertilizer and topsoil are backfilled into the hole left after the protective rod 2 is removed using the backfiller 4;

[0016] The backfiller 4 includes a funnel-shaped main body 41, and a straight pipe 42 is provided at the bottom of the funnel-shaped main body 41. The outer diameter of the straight pipe 42 is less than or equal to the outer diameter of the protective rod 2.

[0017] The transport vehicle 5 is equipped with a storage rack 51, through which the protective rod 2 is placed. The transport vehicle 5 is also equipped with two insert rods, through which the pressure plate 1 is placed.

[0018] The present invention also provides a method for recycling cutting protection devices used in plant modification of abandoned mining areas, which is implemented by the recycling equipment for cutting protection devices used in plant modification of abandoned mining areas described above.

[0019] The method includes the following steps:

[0020] Step 1: Pry up one side of pressure plate 1, with a lifting height of 3-5cm;

[0021] Step 2: Control the pressure plate 1 to fall back to the ground, and further lift the guard bar 2, which has been raised 3-5cm high, to a height of 5-10cm.

[0022] Step 3: Pull out the raised guard bar 2;

[0023] Step 4: Insert the bottom end of the backfiller 4 into the through hole of the pressure plate 1, and backfill fertilizer and topsoil into the hole of the protective rod 2 through the backfiller 4.

[0024] Step 5: Repeat steps 1 to 4 until all the guard rods 2 have been pulled out and the holes in each guard rod 2 have been backfilled with fertilizer and topsoil.

[0025] Step 6: Remove and recycle pressure plate 1;

[0026] Step 7: Place the pressure plate 1 and the protective rod 2 on the transport vehicle 5.

[0027] In step 1, the jaws 33 are inserted into the lifting groove 11 of the pressure plate 1, the support platform 32 is placed on the ground, and the pressure plate 1 is lifted by pressing the pressure rod 31.

[0028] In step 2, after the pressure plate 1 falls back to the ground, the jaws 33 are inserted between the end 21 and the pressure plate 1, the support platform 32 is placed on the ground, and the protective rod 2 is lifted by pressing the pressure rod 31.

[0029] In step 4, fertilizer and topsoil are backfilled using a rod-shaped structure with an outer diameter slightly smaller than that of the protective rod 2, and then compacted.

[0030] In step 6, the pressure plate 1 is rotated outward to enlarge the notch on the pressure plate 1, and then the pressure plate 1 is removed without touching the cutting plant.

[0031] The beneficial effects of this invention include:

[0032] (1) The recycling equipment and method for plant modification of abandoned mining areas provided by the present invention can quickly and efficiently recycle the cutting protection device.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0054] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0055] This invention provides a recycling device for a cutting protection device used in the modification of abandoned mining areas, wherein the cutting protection device is as follows: Figure 1 As shown, it includes a pressure plate 1 and a protective rod 2;

[0056] The pressure plate 1 is an arc-shaped object with one end open, and is attached to the ground around the insertion hole. The pressure plate 1 has multiple through holes for the protective rod 2 to pass through.

[0057] The protective rod 2 passes downward through the through hole on the pressure plate 1 and extends into the soil at the bottom of the cutting hole along the inner wall of the cutting hole. Multiple protective rods 2 are evenly distributed around the cutting plant.

[0058] An end 21 is provided at the end of the protective rod 2, and the end cannot pass through the through hole on the pressure plate 1;

[0059] Preferably, the protective rod 2 is provided with 4 rods, the length of which is greater than the depth of the cutting hole, so as to ensure that the bottom end of the protective rod 2 can extend into the soil at the bottom of the cutting hole; correspondingly, 4 through holes are evenly distributed on the pressure plate 1.

[0060] When arranging the cutting protection device, the pressure plate 1 should be close to the ground and basically concentric with the cutting hole; the protective rod 2 should be fully inserted into the cutting hole, and the end 21 of the protective rod 2 should be close to the pressure plate 1.

[0061] Preferably, a lifting groove 11 is provided on the side of the pressure plate 1; preferably, two lifting grooves 11 are symmetrically provided; the lifting groove 11 can be a blind hole formed by inward recess or a through hole, which can allow the jaws to be inserted and thereby lift and tilt the pressure plate 1.

[0062] Preferably, the pressure plate 1 has a notch on one side, and the pressure plate is an open ring, which facilitates the removal of the cutting from the side; more preferably, a pivot is provided on the side of the pressure plate 1 opposite to the notch, and the pressure plate can be rotated and bent outward, thereby widening the notch and ensuring that the pressure plate can be removed smoothly.

[0063] Preferably, such as Figure 2 , Figure 3 and Figure 4 As shown, the recycling equipment includes a lifting device 3, a backfiller 4, and a transport vehicle 5;

[0064] The lifting device 3 lifts the pressure plate 1 and the protective rod 2 to facilitate the removal of the protective rod 2. After all the protective rods 2 penetrating the pressure plate 1 are removed, the pressure plate 1 can be recycled.

[0065] Fertilizer and topsoil are backfilled into the hole left after the protective rod 2 is removed using the backfiller 4;

[0066] The transport vehicle 5 transports fertilizer, topsoil, and the recycled pressure plate 1 and guardrail 2.

[0067] In a preferred embodiment, such as Figure 2 As shown, the lifting device 3 includes a pressure rod 31, a support platform 32, and a jaw 33 connected in sequence;

[0068] The support platform 32 is located on the ground, and the jaws 33 can extend into the lifting groove 11 on the pressure plate 1, thereby lifting the pressure plate 1 by pressing the pressure rod 31;

[0069] The jaws 33 can also clamp the end 21 of the protective rod 2, thereby prying up the protective rod 2 by pressing the pressure bar 31.

[0070] The jaws 33 are flat and have notches to accommodate the protective rod.

[0071] In a preferred embodiment, such as Figure 3 As shown, the backfiller 4 includes a funnel-shaped main body 41, with a straight pipe 42 at the bottom of the funnel-shaped main body 41. The outer diameter of the straight pipe 42 is less than or equal to the outer diameter of the protective rod 2. The length of the straight pipe 42 can reach one-third to one-half of the length of the protective rod. The backfilling of fertilizer and topsoil, with a rod-like structure whose outer diameter is slightly smaller than that of the protective rod 2, is assisted by compaction, achieving complete filling of the holes in the protective rod.

[0072] In a preferred embodiment, such as Figure 4 As shown, a storage rack 51 is provided on the transport vehicle 5, through which the protective rod 2 is placed. Two insertion rods are also provided on the transport vehicle 5, through which the pressure plate 1 is placed. The storage rack 51 includes two layers of grid plates. The protective rod 2 is vertically inserted into the grid plates. The gap size of the grid plates is between the outer diameter and the end size of the protective rod, ensuring that the protective rod is vertically arranged and fixed in the storage rack 51.

[0073] The present invention also provides a method for recycling cutting protection devices used in plant modification of abandoned mining areas, which is implemented by the recycling equipment for cutting protection devices used in plant modification of abandoned mining areas described above.

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

[0075] Step 1: Pry up one side of pressure plate 1, with a lifting height of 3-5cm;

[0076] Step 2: Control the pressure plate 1 to fall back to the ground, and further lift the guard bar 2, which has been raised 3-5cm high, to a height of 5-10cm.

[0077] Step 3: Pull out the raised guard bar 2;

[0078] Step 4: Insert the bottom end of the backfiller 4 into the through hole of the pressure plate 1, and backfill fertilizer and topsoil into the hole of the protective rod 2 through the backfiller 4.

[0079] Step 5: Repeat steps 1 to 4 until all the guard rods 2 have been pulled out and the holes in each guard rod 2 have been backfilled with fertilizer and topsoil.

[0080] Step 6: Remove and recycle pressure plate 1;

[0081] Step 7: Place the pressure plate 1 and the protective rod 2 on the transport vehicle 5.

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

[0083] Preferably, in step 2, after the pressure plate 1 falls back to the ground, the jaws 33 are inserted between the end 21 and the pressure plate 1, the support platform 32 is placed on the ground, and the protective rod 2 is lifted by pressing the pressure rod 31.

[0084] In this application, the clamps 33 and the lifting groove 11 work together to lift the pressure plate 1, thereby lifting the protective rod 2. This creates a gap between the protective rod 2 and the pressure plate 1, allowing the clamps 33 to be inserted between the end of the protective rod 2 and the pressure plate 1, further lifting the protective rod 2. When the protective rod 2 is lifted to a sufficient height, it can be easily grasped and pulled out. This operation process can basically ensure the stability of the protective rod pulling and retrieval process. The entire pulling process is also 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 cuttings and the surrounding environment during the pulling process, and improve the survival rate of cuttings in abandoned mining areas.

[0085] In a preferred embodiment, in step 4, a rod-shaped structure with an outer diameter slightly smaller than that of the protective rod 2 is used to assist in backfilling fertilizer and topsoil, and to compact them. The rod-shaped structure is inserted into the funnel-shaped main body to accelerate the settling speed of the fertilizer and topsoil within the main body. As the backfilling work continues, the funnel-shaped main body is gradually lifted upwards. After the funnel-shaped main body has completely detached from the pressure plate, the rod-shaped structure is then inserted into the through-hole of the pressure plate to compact the fertilizer and topsoil.

[0086] In a preferred embodiment, in step 6, the pressure plate 1 is rotated outward to enlarge the notch on the pressure plate 1, and then the pressure plate 1 is removed without touching the cutting.

[0087] Example

[0088] In the abandoned mining area undergoing renovation, 1,000 cuttings have passed the rooting and survival period, and the protective devices at the cutting holes can be removed. The protective devices are then recycled using the same method described for recycling cuttings in the abandoned mining area. The specific recycling method for each protective 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, and lift it to a height of 3-5cm.

[0090] Step 2: Remove the jaws, control the pressure plate to fall back to the ground, then insert the jaws between the end and the pressure plate to clamp the guard bar, and lift the guard bar that has been raised 3-5cm high, with a lifting height of 5-10cm.

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

[0092] Step 4: Insert the bottom end of the backfiller into the through hole of the pressure plate, and backfill fertilizer and topsoil into the hole of the guard rod through the backfiller, and tamp it down;

[0093] Step 5: Repeat steps 1 to 4 until all 4 guard rods are pulled out and the holes in each guard rod are backfilled with fertilizer and topsoil.

[0094] Step 6: Rotate and bend the pressing plate outward to enlarge the notch on the pressing plate, and remove and recycle the pressing plate without touching the cuttings;

[0095] Step 7: Place the pressure plate and protective rod on the transport vehicle. Each transport vehicle can carry 50 sets of cutting protection devices. After the vehicle is fully loaded, transport the cutting protection devices to the centralized processing station, unload the cutting protection devices, add fertilizer and topsoil, and then continue the recycling operation of the cutting protection devices.

[0096] Ten people were mobilized to operate ten sets of recycling equipment for plant-modified cutting protection devices in abandoned mining areas. The recycling method for the plant-modified cutting protection devices in abandoned mining areas was implemented. The recycling operation of all cutting protection devices was completed in a total of 8.2 hours. The average recycling time for each cutting protection device was less than 5 minutes, which has high operational efficiency and can be applied on a large scale.

[0097] Further, 100 cuttings were randomly selected from 1,000 cuttings, and their growth and development were continuously monitored over the next month. It was found that 98 cuttings grew successfully and were not affected by the retrieval of the cutting protection device. The two cuttings that failed to grow normally were due to insufficient root development.

[0098] As can be seen from the above embodiments, the recycling method for plant-modified cutting protection devices in abandoned mining areas provided in this application has high work efficiency and extremely high reliability.

[0099] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present invention based on these embodiments, all of which fall within the scope of protection of the present invention.
