Description

Technical Field

[0001] This invention relates to technology for the transformation of abandoned mining areas, specifically to a cutting and drilling protective device and method for transforming abandoned mining areas using plants. 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] Based on this, the inventors have designed a cutting hole drilling protection device and method for transforming abandoned mining areas with plants. This device and method can be used for drilling cutting holes and subsequent protection work in abandoned mining areas, so that the cutting plants can grow safely for a period of time after cutting and ensure the survival rate of cuttings. Summary of the Invention

[0005] To overcome the aforementioned problems, the inventors conducted in-depth research and designed a cutting and drilling protection device and method for modifying abandoned mining areas with plants. In this device and method, a high-strength alloy drill bit is used to drill cutting holes in the mining area. The device simultaneously carries an adjusting block and a suction cup to ensure that a protective rod is driven into the cutting hole. This protective rod consists of multiple vertically arranged, thin metal rods evenly distributed on the inner wall of the cutting hole. The bottom end of the protective rod is inserted into the soil below the cutting hole, and the top end of the protective rod is fixed by a pressure plate, providing lateral support for the cutting hole. Simultaneously, the pressure plate also provides protection for the cutting hole and the plant within it from above. Once the plant has grown to a certain stage, the pressure plate and protective rods can be removed and recycled, preventing them from hindering further plant growth. This device enables a one-stop solution for drilling cutting holes and installing protective rods, improving work efficiency and thus completing this invention.

[0006] Specifically, the purpose of this invention is to provide a cutting and drilling protection device for modifying abandoned mining areas with plants. The device includes a main frame 1, a feed hydraulic cylinder 2 is provided above the main frame 1, an adjustment block 3 connected to the feed hydraulic cylinder 2 is provided inside the main frame 1, and a drill rod 4 and a suction cup 5 are provided on the adjustment block 3.

[0007] The adjusting block 3 is rotatably connected to the feed hydraulic cylinder 2, so that the drill rod 4 or the suction cup 5 faces downward, and the suction cup 5 is optionally equipped with a pressure plate 6 and a protective rod 7;

[0008] Driven by the feed hydraulic cylinder 2, the drill rod 4 is fed downwards to drill holes, or the suction cup 5 is fed downwards to install the protective rod 7.

[0009] A rotating frame 21 is provided at the bottom of the hydraulic cylinder 2, the adjusting block 3 is mounted on the rotating frame 21, and a steering motor 22 is provided on the rotating frame 21 to drive the adjusting block 3 to rotate.

[0010] The rotating frame 21 is also provided with a limiting mechanism 23, which locks the adjusting block 3 so that the adjusting block 3 is stable and without deflection when it is fed downward.

[0011] When the suction cup 5 is fed downward, the pressure plate 6 is adsorbed on the suction cup 5, and the suction cup 5 and the pressure plate 6 together limit and fix multiple protective rods 7, so that the multiple protective rods 7 are inserted downward simultaneously into the insertion hole drilled by the drill rod 4.

[0012] The pressure plate 6 is in the shape of a semi-circular arc and has multiple through holes for the protective rod 7 to pass through.

[0013] An end 71 is provided at the end of the protective rod 7, and the end cannot pass through the through hole on the pressure plate 6;

[0014] Multiple blind holes 51 are provided on the suction cup 5, and the end 71 is embedded in the blind holes 51 to provide positioning and limiting for the pressure plate 6.

[0015] The suction cup 5 is equipped with an electromagnet, which is energized to attract the pressure plate 6 and fix the protective rod 7.

[0016] By controlling the electromagnet to de-energize, the suction cup 5 is released from the pressure plate 6, causing the suction cup 5 to detach from the pressure plate 6 and the protective rod 7.

[0017] When the protective rod 7 is pressed into the insertion hole, and the suction cup 5 is separated from the pressure plate 6 and the protective rod 7, the pressure plate 6 is pressed against the ground and surrounds the insertion hole.

[0018] A lifting groove 61 is provided on the side of the pressure plate 6;

[0019] After the cutting operation is completed within the predetermined time, the lifting groove 61 is used to lift the pressure plate 6 upwards, so that the pressure plate 6 is separated from the ground. The protective rods 7 are removed one by one and retrieved, and finally the pressure plate 6 is retrieved.

[0020] A telescopic rod 8 is vertically installed below the main frame 1, and a caster wheel 9 is installed at the bottom of the telescopic rod 8.

[0021] By controlling the extension of the telescopic rod 8, the main frame 1 is kept in a horizontal state when the feed hydraulic cylinder 2 is working.

[0022] The present invention also provides a method for propagation and protection of abandoned mining areas by planting plants, which is implemented by the propagation and protection device for the transformation of abandoned mining areas by planting plants described above.

[0023] The method includes the following steps:

[0024] Step 1: Move the main frame 1 to the position where the cuttings will be inserted;

[0025] Step 2: Adjust the length of the telescopic rod 8 to make the main frame 1 horizontal;

[0026] Step 3: Rotate the adjusting block 3 so that the drill rod 4 faces downward;

[0027] Step 4: Drive the drill rod 4 downward by the feed hydraulic cylinder 2, and at the same time control the rotation of the drill rod 4 to drill the insertion hole at the predetermined position;

[0028] Step 5: Pull the drill rod upward out of the insertion hole, and install the pressure plate 6 and the protective rod 7 on the suction cup 5;

[0029] Step 6: Rotate the adjusting block 3 so that the suction cup 5 and the protective rod 7 face downwards;

[0030] Step 7: Drive the suction cup 5 and the protective rod 7 downward by the feed hydraulic cylinder 2, so that the protective rod 7 is inserted into the cutting hole from the edge of the cutting hole. Finally, the lower end of the protective rod 7 extends into the bottom of the cutting hole, and the pressure plate 6 is attached to the ground at the edge of the cutting hole.

[0031] Step 8: The suction cup 5 disengages from the pressure plate 6, and the suction cup 5 returns to its initial position as the adjusting block 3 moves upward.

[0032] The beneficial effects of this invention include:

[0033] (1) According to the present invention, the cutting hole protection device and method for transforming abandoned mining areas by plants provides protection for the cutting hole and the plant therein by means of a pressure plate and a protective rod, ensuring that the plant can successfully pass through the fragile new root sprouting stage and other cutting growth stages, and ultimately improve the cutting survival rate and improve the cutting transformation effect.

[0062] 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.

[0063] 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.

[0064] This invention provides a cutting and drilling protective device for modifying abandoned mining areas using plants, such as... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a main frame 1, a feed hydraulic cylinder 2 is arranged above the main frame 1, the feed hydraulic cylinder 2 is arranged vertically with the telescopic rod pointing downwards, and the hydraulic pump is located at the top of the main frame; an adjusting block 3 connected to the feed hydraulic cylinder 2 is arranged inside the main frame 1, the adjusting block 3 can reciprocate in the vertical direction as the feed hydraulic cylinder 2 extends and retracts; a drill rod 4 and a suction cup 5 are arranged on the adjusting block 3;

[0065] The drill rod 4 is an alloy drill rod with alloy fins. The drill rod 4 can rotate on its own. The drive motor for rotation is located inside the adjustment block. When the drill rod 4 is fed downwards to drill a cutting hole, the drive motor starts synchronously, and the drill rod 4 rotates to drill.

[0066] The adjusting block 3 is rotatably connected to the feed hydraulic cylinder 2, so that the drill rod 4 or the suction cup 5 faces downward. The suction cup 5 is optionally equipped with a pressure plate 6 and a protective rod 7. Under the drive of the feed hydraulic cylinder 2, the drill rod 4 feeds downward to drill a hole or the suction cup 5 feeds downward to install the protective rod 7.

[0067] In a preferred embodiment, such as Figure 5 As shown, a rotating frame 21 is provided at the bottom end of the hydraulic cylinder 2, the adjusting block 3 is mounted on the rotating frame 21, and a steering motor 22 is provided on the rotating frame 21 to drive the adjusting block 3 to rotate.

[0068] Preferably, the rotating frame 21 includes upright plates located at both ends of the adjusting block 3, with coaxial through holes on the upright plates. Coaxial rotating shafts are provided at both ends of the adjusting block 3, and the rotating shafts extend into the through holes and can reciprocate within the through holes. The rotating shaft of the steering motor 22 is connected to the rotating shaft of the adjusting block 3 through gears, thereby driving the adjusting block to rotate. Under the control of the steering motor 22, the adjusting block 3 can reciprocate within a 90-degree range, thereby achieving the switching between the two states of the drill rod 4 or the suction cup 5 facing downwards. More preferably, a physical limiting mechanism is set to ensure that each rotation can only be 90 degrees.

[0069] Preferably, a limiting mechanism 23 is also provided on the rotating frame 21 to lock the adjusting block 3, so that the adjusting block 3 has a stable posture without deflection when it is fed downward.

[0070] Preferably, such as Figure 6 As shown, the limiting mechanism 23 includes a sliding plate 231, a threaded rod 232 is provided at the bottom of the sliding plate 231, and a drive motor 211 is provided at the bottom of the rotating frame 21. The threaded rod 232 and the sliding plate 231 are controlled to reciprocate in the horizontal direction through the cooperation between the drive motor 211 and the threaded rod 232.

[0071] More preferably, a horizontal notch is started on the rotating frame 21, and one end of the sliding plate 231 is embedded in the notch, which provides a limit for the sliding plate 231. A three-sided baffle 233 is provided on the other end of the sliding plate 231. When the three-sided baffle 233 moves to a predetermined position with the sliding plate 231, the three-sided baffle 233 fully contacts the adjusting block, thereby providing a complete limit for the adjusting block 3 and preventing the adjusting block 3 from deflecting or moving during the feeding process.

[0072] Therefore, before performing the feeding operation, the adjusting block 3 needs to be limited by the limiting mechanism 23. Before rotating the adjusting block 3, the limiting mechanism 23 needs to be moved to release the limiting of the adjusting block 3.

[0073] In a preferred embodiment, such as Figure 7As shown, when the suction cup 5 feeds downwards, the pressure plate 6 adheres to the suction cup 5, and the suction cup 5 and the pressure plate 6 together limit and fix multiple protective rods 7, so that the multiple protective rods 7 are simultaneously inserted downwards into the cutting hole drilled by the drill rod 4. Since both drilling and the installation of the protective rods 7 are powered by the feed hydraulic cylinder 2, and the main frame does not move during operation, it can be ensured that the positions of the two feeds are completely consistent, ensuring that the protective rods 7 can be synchronously inserted into the cutting hole with precise and unbiased insertion.

[0074] An end 71 is provided at the end of the protective rod 7, and the end cannot pass through the through hole on the pressure plate 6;

[0075] Multiple blind holes 51 are provided on the suction cup 5, and the end 71 is embedded in the blind holes 51 to provide positioning and limiting for the pressure plate 6.

[0076] Preferably, the pressure plate 6 is in the shape of a semi-circular arc and has multiple through holes for the protective rod 7 to pass through. When installing the pressure plate 6 and the protective rod 7, the protective rod 7 needs to be inserted into the through hole of the pressure plate 6 first, and then the end 71 carrying the protective rod 7 should be pressed against the suction cup 5.

[0077] Preferably, the suction cup 5 is equipped with an electromagnet, and the pressure plate 6 is attracted and the protective rod 7 is fixed by controlling the electromagnet to be energized;

[0078] By controlling the electromagnet to de-energize, the suction cup 5 is released from the pressure plate 6, causing the suction cup 5 to detach from the pressure plate 6 and the protective rod 7.

[0079] Preferably, the protective rod 7 is provided with 4 rods, the length of which is greater than the length of the drill rod 4, so as to ensure that the bottom end of the protective rod 7 can extend into the soil at the bottom of the cutting hole; correspondingly, 4 through holes are evenly distributed on the pressure plate 6.

[0080] In a preferred embodiment, when the protective rod 7 is pressed into the insertion hole and the suction cup 5 is disengaged from the pressure plate 6 and the protective rod 7, the pressure plate 6 is pressed against the ground and surrounds the insertion hole.

[0081] A lifting groove 61 is provided on the side of the pressure plate 6;

[0082] After the cutting operation is completed within the predetermined time, that is, after the cuttings have passed the rooting and survival period, the lifting groove 61 is used to lift the pressure plate 6 upward, so that the pressure plate 6 is separated from the ground, and the protective rods 7 are taken out one by one and retrieved, and finally the pressure plate 6 is retrieved.

[0083] Preferably, the pressure plate 6 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 6 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.

[0084] In a preferred embodiment, such as Figure 4 As shown, a telescopic rod 8 is vertically arranged below the main frame 1, and a caster wheel 9 is arranged at the bottom of the telescopic rod 8;

[0085] By controlling the extension of the telescopic rod 8, the main frame 1 is in a horizontal state when the feed hydraulic cylinder 2 is working. In this application, the telescopic rods 8 are controlled independently to adapt to complex ground conditions.

[0086] The present invention also provides a method for propagation and protection of abandoned mining areas by planting plants, which is implemented by the propagation and protection device for the transformation of abandoned mining areas by planting plants described above.

[0087] Preferably, the method includes the following steps:

[0088] Step 1: Move the main frame 1 to the position where the cuttings will be inserted;

[0089] Step 2: Adjust the length of the telescopic rod 8 to make the main frame 1 horizontal;

[0090] Step 3: Rotate the adjusting block 3 so that the drill rod 4 faces downward;

[0091] Step 4: Drive the drill rod 4 downward by the feed hydraulic cylinder 2, and at the same time control the rotation of the drill rod 4 to drill the insertion hole at the predetermined position;

[0092] Step 5: Pull the drill rod upward out of the insertion hole, and install the pressure plate 6 and the protective rod 7 on the suction cup 5;

[0093] Step 6: Rotate the adjusting block 3 so that the suction cup 5 and the protective rod 7 face downwards;

[0094] Step 7: Drive the suction cup 5 and the protective rod 7 downward by the feed hydraulic cylinder 2, so that the protective rod 7 is inserted into the cutting hole from the edge of the cutting hole. Finally, the lower end of the protective rod 7 extends into the bottom of the cutting hole, and the pressure plate 6 is attached to the ground at the edge of the cutting hole.

[0095] Step 8: The suction cup 5 disengages from the pressure plate 6, and the suction cup 5 returns to its initial position as the adjusting block 3 moves upward.

[0096] 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.
