Description

Technical Field

[0001] This invention relates to the field of surface covering technology for spoil heaps, and more specifically, to a method for surface covering spoil heaps in desert and Gobi mining areas. Background Technology

[0002] Waste dumps in desert and Gobi mining areas are sites where large amounts of waste are generated during mining operations. This waste, including excess soil and rocks, is typically piled up within these dumps. Without effective surface covering, waste dumps can easily lead to soil erosion, environmental pollution, and ecological damage. To avoid these problems, covering waste dumps is a common practice. Surface covering of waste dumps in desert and Gobi mining areas is a crucial step in the mining process, aiming to protect surface soil, mitigate wind erosion, control soil erosion, and prevent pollution. However, in desert and Gobi regions, due to the arid climate, strong winds, and complex terrain, surface covering of waste dumps is quite challenging. Traditional covering methods are mostly manual, which are not only inefficient but also difficult to guarantee effective coverage. Furthermore, because the ecological environment of desert and Gobi regions is fragile, inappropriate covering methods may have adverse effects on the local ecosystem.

[0003] Some studies have begun to focus on the selection and application methods of surface covering materials for spoil heaps in order to improve the covering effect and reduce environmental impact. However, traditional manual covering methods are inefficient and ineffective, failing to meet the needs of large-scale mining spoil heaps. Furthermore, manual covering involves a large workload, and the entry of personnel into the spoil heap poses certain dangers and operational difficulties, further reducing the efficiency of the covering operation. Therefore, we propose a surface covering method for spoil heaps in desert and Gobi mining areas. Summary of the Invention

[0004] The purpose of this invention is to provide a method for covering the surface of spoil heaps in desert and Gobi mining areas, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a method for surface covering of spoil heaps in desert and Gobi mining areas, comprising the following steps:

[0006] I. Material loading and assembly stage

[0007] S1. Remove the buckle from the hook and open the rear cover to connect the rear of the storage rack to the outside.

[0008] S2. Place the cover net on the storage rack along the back side to complete the loading operation. After loading, close the back cover and continue to fasten the buckle on the hook.

[0009] S3. Pass the end of the cover net through the two rollers, and at the same time, pass the end of the cover net through the two tension rollers to complete the arrangement operation;

[0010] II. Pressing and Fixing Stage

[0011] S4. First, stretch the end of the covering net that passes between the two rollers and lay it on the surface of the soil.

[0012] S5. Start the cylinder and make it work. When the cylinder works, it drives the support frame, drive motor and roller to move downward. The roller presses the end of the cover net to the soil surface.

[0013] S6. As the external vehicle moves and moves the device along with it, start the drive motor and make it work. The drive motor works and drives the roller to rotate along the ground, so as to stretch and press the cover net down to fit the soil surface and complete the covering operation.

[0014] III. Heat Dissipation Stage

[0015] S7. Connect the first hose to the external cooling water inlet pipe and the second hose to the external return pipe. As the external cooling water enters through the first hose, the cooling water enters the serpentine pipe to cool the drive motor part inside the heat sink.

[0016] The technical solution of this invention includes a storage rack for the surface covering method of the waste dumping site in the desert and Gobi mining area. The storage rack is installed on a surface covering vehicle in the mining area. The bottom wall of the front end of the storage rack is provided with a through hole that communicates with the outside. A covering net is installed inside the storage rack. Side plates are fixedly installed on both the left and right side plates of the storage rack. An arrangement assembly is provided at the bottom of the storage rack. The arrangement assembly includes two symmetrical cylinders fixedly installed on the bottom surface of the side plates. A support frame is provided on the telescopic shaft of the two cylinders. A drive motor is fixedly installed on the end plate of the support frame. A roller is fixedly installed at the end of the output shaft of the drive motor. The roller is rotatably connected to one side plate of the support frame through a rotating shaft, which facilitates the use of the roller to press the covering net onto the surface of the soil to complete the covering operation.

[0017] In the technical solution of the present invention, a rectangular plate is fixedly installed at the end of the telescopic shaft of the cylinder, and the support frame is fixedly installed on the bottom surface of the two rectangular plates, which facilitates the fixed installation operation of the support frame.

[0018] In the technical solution of the present invention, multiple sets of pressing cones arranged in a ring at equal intervals are fixedly installed on the annular side of the compaction wheel. The pressing cones are used for pressing the cover net into the soil.

[0019] In the technical solution of the present invention, a heat sink is provided on the side of the support frame to protect the drive motor inside. A fixing frame is fixedly installed at the end of the heat sink. The fixing frame is fixedly installed on the support frame by a plurality of fastening screws, which facilitates the fixing of the fixing frame and achieves the effect of fixing the heat sink. The heat sink protects the drive motor inside and can play the role of anti-collision protection.

[0020] In the technical solution of the present invention, an inlet pipe and an outlet pipe are fixedly installed on the top plate of the heat sink, and the inlet pipe and the outlet pipe are connected by a serpentine tube located inside the heat sink. A first flexible hose is fixedly installed at the top of the inlet pipe, and a second flexible hose is fixedly installed at the end of the outlet pipe, so as to facilitate the cooling and heat dissipation operation of the drive motor part after water is introduced.

[0021] In the technical solution of the present invention, a plurality of equally spaced support beams are fixedly installed on the top surface of the storage rack, and the support beams are fixedly installed on the external vehicle body, thereby realizing the fixed installation of the storage rack on the external vehicle body.

[0022] In the technical solution of the present invention, the rear side of the storage rack is connected to the outside. Two symmetrical hooks are fixedly installed on the top surface of the rear end plate of the storage rack. A rear cover plate is hinged to the rear side of the storage rack. Two symmetrical buckles are fixedly installed on the top surface of the rear cover plate. The buckles and the hooks engage with each other, which facilitates the sealing operation of the rear side of the storage rack by using the rear cover plate to prevent the cover net from falling off the storage rack.

[0023] In the technical solution of the present invention, two symmetrical rollers are rotatably connected between the left and right side walls of the through hole via a rotating shaft. The end of the covering net passes through the two rollers. The rollers help to reduce friction and make the covering net easier to unfold for covering.

[0024] In the technical solution of the present invention, an anti-loosening component is provided on the bottom surface of the storage rack. The anti-loosening component includes two symmetrical horizontal plates at the front and rear. A plurality of vertical plates for support are fixedly installed between the horizontal plates and the bottom surface of the storage rack. A plurality of guide holes arranged linearly and equally spaced are provided on the vertical plates. Two symmetrical U-shaped frames are provided between the two vertical plates. Tensioning rollers are rotatably connected between the left and right side plates of the U-shaped frames. A plurality of equally spaced guide rods are fixedly installed on the rear side of the U-shaped frames. The guide rods pass through the guide holes and are slidably connected to the guide holes. A plurality of springs arranged linearly and equally spaced are fixedly installed between the U-shaped frames and the horizontal plates. The springs are wound around the guide rods. The two tensioning rollers are located on the left and right sides of the through hole, respectively. The tensioning rollers can be used to properly press the covering net, so that the covering net will not easily open.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention uses a storage rack to store the covering net and a set arrangement component to press the covering net onto the ground using a pressing roller. As the pressing roller rotates and moves forward, the covering net is simultaneously unfolded and pressed onto the ground to complete the covering operation. The operation is simple and achieves the effect of facilitating the covering operation and saving manpower.

[0027] 2. The present invention, through the anti-loosening component, can properly press the cover net passing through the two tension rollers, so that the cover net will not open randomly without the action of external force, which is conducive to ensuring that the cover net is evenly opened for covering and laying operations.

[0028] 3. The present invention can provide anti-collision protection for the drive motor through the heat dissipation cover, and can also pass water through the serpentine tube and other components to dissipate heat and cool the drive motor. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-9 The present invention provides a method for covering the surface of spoil heaps in desert and Gobi mining areas, comprising the following steps:

[0045] I. Material loading and assembly stage

[0046] S1. Remove the buckle 12 from the hook 13 and flip the rear cover 11 to open it, so that the rear of the storage rack 1 is connected to the outside.

[0047] S2. Place the cover net 2, which is placed on the ground and rolled up, on the storage rack 1 along the back side of the storage rack 1. Place an appropriate number of cover nets 2 according to the specific space of the storage rack 1 to complete the loading operation. After loading, flip the rear cover plate 11 and close it. Then, continue to fasten the buckle 12 on the hook 13 to assemble the cover net 2 onto the storage rack 1.

[0048] S3. Since the covering net 2 is rolled up, the end of the covering net 2 is unfolded and passed through the two rollers 141. At the same time, the end of the covering net 2 is passed through the two tension rollers 43 to complete the arrangement operation. At this time, under the elastic force of the spring 45, the two tension rollers 43 can drive the passing covering net 2 to press it appropriately, so that the covering net 2 will not easily unfold when there is no external force dragging it.

[0049] II. Pressing and Fixing Stage

[0050] S4. First, stretch the end of the covering net 2 that passes between the two rollers 141 and lay it on the surface of the soil, so that the covering net 2 passes under the roller 34.

[0051] S5. Start the cylinder 30 and make it work. The cylinder 30 works, which drives the support frame 32, drive motor 33 and roller 34 to move downward. The roller 34 is used to press the end of the cover net 2 onto the soil surface.

[0052] S6. After the device moves along with the external vehicle, start the drive motor 33 and make it work. The drive motor 33 works and drives the roller 34 to rotate along the ground, so as to stretch the cover net 2 and press it down to fit the soil surface. As the roller 34 rotates, the roller 34 can pull the cover net 2 in the storage rack 1 to unfold, completing the operation of unfolding and covering the cover net 2 at the same time.

[0053] III. Heat Dissipation Stage

[0054] S7. Connect the first hose 371 to the external cooling water inlet pipe and the second hose 381 to the external return pipe. As the external cooling water enters through the first hose 371, the cooling water enters the serpentine pipe 39 to cool the drive motor 33 inside the heat sink 36.

[0055] In this embodiment, a storage rack 1 is included, which adopts the surface covering method for the waste dumping site in the desert Gobi mining area. The storage rack 1 is set on the surface covering vehicle in the mining area. Multiple support beams 10 arranged at equal intervals are fixedly installed on the top surface of the storage rack 1. The support beams 10 are fixedly installed on the external vehicle body, so that the storage rack 1 can be fixedly installed on the external vehicle body, and the device can be moved synchronously with the movement of the external vehicle to carry out the covering operation on the waste dumping site.

[0056] Specifically, the storage rack 1 has an outlet hole 14 on its front bottom wall that connects to the outside. A covering net 2 is installed inside the storage rack 1. Side plates 15 are fixedly installed on both the left and right sides of the storage rack 1. An arrangement assembly 3 is installed at the bottom of the storage rack 1. The arrangement assembly 3 includes two symmetrical cylinders 30 fixedly installed on the bottom surface of the side plates 15. Support frames 32 are installed on the telescopic shafts of the two cylinders 30. A drive motor 33 is fixedly installed on the end plate of the support frame 32. A roller 34 is fixedly installed at the end of the output shaft of the motor 33. The roller 34 is rotatably connected to one side plate of the support frame 32 through a rotating shaft. The end of the covering net 2 passes through the through hole 14 and passes through the part of the covering net 2 through the through hole 14 and passes under the roller 34. As the roller 34 presses the covering net 2 firmly onto the ground, the roller 34 rotates and the vehicle moves, thus completing the covering operation by pressing the covering net 2 onto the surface of the soil.

[0057] In this embodiment, a rectangular plate 31 is fixedly installed at the end of the telescopic shaft of the cylinder 30, and a support frame 32 is fixedly installed on the bottom surface of the two rectangular plates 31, which facilitates the fixed installation of the support frame 32.

[0058] Specifically, multiple sets of pressing cones 35 arranged in a ring at equal intervals are fixedly installed on the annular side of the compaction roller 34. The pressing cones 35 are truncated cones and are used for pressing the cover net 2 into the soil. When the compaction roller 34 rolls, the pressing cones 35 can press the corresponding parts of the cover net 2 into the soil.

[0059] Furthermore, a heat sink 36 for protecting the drive motor 33 inside is provided on the side of the support frame 32. A fixing frame 361 is fixedly installed at the end of the heat sink 36. The fixing frame 361 is fixedly installed on the support frame 32 by multiple fastening screws, which facilitates the fixing of the fixing frame 361 and achieves the effect of fixing the heat sink 36. The heat sink 36 protects the drive motor 33 inside and can play the role of anti-collision protection.

[0060] In addition, an inlet pipe 37 and an outlet pipe 38 are fixedly installed on the top plate of the heat sink 36. The inlet pipe 37 and the outlet pipe 38 are connected by a serpentine pipe 39, which is located inside the heat sink 36. A first flexible hose 371 is fixedly installed at the top of the inlet pipe 37, and a second flexible hose 381 is fixedly installed at the end of the outlet pipe 38. This facilitates the cooling and heat dissipation of the drive motor 33 after water is introduced. The first flexible hose 371 and the second flexible hose 381 are flexible hoses, so they will not obstruct the normal up and down movement of the support frame 32. In addition, as the cooling water enters the serpentine pipe 39, it can exchange heat with the heat sink 36, thereby achieving the effect of cooling the drive motor 33.

[0061] It is worth noting that the rear side of the storage rack 1 is connected to the outside. Two symmetrical hooks 13 are fixedly installed on the top surface of the rear end plate of the storage rack 1. A rear cover plate 11 is hinged to the rear side of the storage rack 1. Two symmetrical buckles 12 are fixedly installed on the top surface of the rear cover plate 11. The buckles 12 and the hooks 13 engage with each other, which makes it easy to use the rear cover plate 11 to seal the rear side of the storage rack 1, preventing the cover net 2 from falling off the storage rack 1. After the rear cover plate 11 is opened, it is easy to place the cover net 2 on the storage rack 1.

[0062] In this embodiment, two symmetrical rollers 141 are rotatably connected between the left and right side walls of the through hole 14 via a rotating shaft. The end of the covering net 2 passes through the two rollers 141. The rollers 141 help to reduce friction, making it easier for the covering net 2 to unfold and cover. The rollers 141 can rotate, which helps to reduce wear on the covering net 2.

[0063] It is worth noting that an anti-loosening component 4 is provided on the bottom surface of the storage rack 1. The anti-loosening component 4 includes two symmetrical horizontal plates 40. Multiple vertical plates 41 for support are fixedly installed between the horizontal plates 40 and the bottom surface of the storage rack 1. Multiple guide holes 401 arranged linearly and at equal intervals are provided on the vertical plates 41. Two symmetrical U-shaped frames 42 are provided between the two vertical plates 41. Tensioning rollers 43 are rotatably connected between the left and right side plates of the U-shaped frames 42. Multiple guide rods 44 arranged at equal intervals are fixedly installed on the rear side of the U-shaped frames 42. The guide rods 44 pass through the guide holes 401 and are slidably connected to the guide holes 401. The U-shaped frames 42 and the horizontal plates 40 are fixedly connected. Multiple springs 45 arranged linearly and at equal intervals are fixedly installed between the holes 0 and 14. The springs 45 are wound around the guide rod 44. Two tension rollers 43 are located on the left and right sides of the through hole 14, respectively. The end of the cover net 2 passes through the two tension rollers 43. The tension rollers 43 can be used to properly press the cover net 2 so that the cover net 2 will not easily open. In addition, when the end of the cover net 2 passes through the two tension rollers 43, in order to ensure smoother passage, the elasticity of the springs 45 can push the two tension rollers 43 to both sides, increasing the distance between the two tension rollers 43. Then the end of the cover net 2 passes through the two tension rollers 43, completing the arrangement operation.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
