Description

Technical Field

[0001] This invention relates to the field of open-pit coal mine thin-layer technology, specifically to a continuous mining equipment and operating method for open-pit coal mine thin-layers. Background Technology

[0002] Coal is my country's primary energy source, and the coal industry is a crucial foundational industry related to energy security and the national economy. my country classifies coal seams less than 1.3 meters thick as thin coal seams and those less than 0.8 meters thick as extremely thin coal seams. Researching efficient mining technologies for thin and extremely thin coal seams is of significant practical importance. However, existing open-pit coal mine thin-seam mining machines use spiral blades on drums to load coal into scraper conveyors. These machines have poor loading performance, resulting in severe coal circulation, excessive coal breakage, and a significant reduction in coal lump size. Furthermore, the drum angle of existing open-pit coal mine thin-seam mining machines is not adjustable, leading to incomplete coal seam excavation and cutting, resulting in missed mining and affecting coal yield. Summary of the Invention

[0023] By adopting the above technical solution, the fixed bearing is used to achieve through-fixation.

[0024] A method for operating thin-layer coal seams in open-pit coal mines:

[0025] First: The overall device drive:

[0026] (1): When the thin layer of open-pit coal mine needs to be mined, the operator starts the kinetic energy supply component to drive the drive component body to operate. When the drive component body moves the whole equipment to the position of the thin layer of open-pit coal mine to be mined, the operator continues to control the drive component body to operate so that the spiral drum and the cutting teeth carried on the surface of the spiral drum come into contact with the thin layer of open-pit coal mine, thereby controlling the powerful drive motor to operate.

[0027] Second: Thin-layer mining operations in open-pit coal mines under horizontal conditions:

[0028] (1): When the powerful drive motor is running, it drives the universal drive shaft to rotate under force. When the universal drive shaft is rotated under force, it drives the driven gear to rotate and mesh with the active gear, and synchronously drives the spiral drum and the cutting teeth on the surface to rotate and move relative to each other, thereby mining the thin layer of open-pit coal mine. The coal blocks that are mined fall onto the lower coal hopper and the lower coal ladder. At this time, the lower coal ladder is under force and moves, so that the coal blocks that fall on the surface are synchronously transported into the lower coal hopper. Through the lower coal sweeping disc and the drive motor, the coal blocks are transported to the main body through the conveying pipe.

[0029] Third: Thin-layer mining operations in open-pit coal mines with a certain angle of inclination above or below:

[0030] (1): When it is necessary to mine the thin layer of coal above the open-pit coal mine, the operator first controls the first hydraulic regulating cylinder to perform bending or stretching movements to drive the installation frame to tilt at an angle. When the installation frame is tilted at an angle, the lower coal ladder, lower coal hopper, universal drive shaft, second ball rod and ball seat are simultaneously tilted at an angle. When the spiral drum and the cutting teeth carried on the surface come into contact with the thin layer of coal above, the motor is driven again to run to mine the thin layer of coal above the open-pit coal mine.

[0031] (2): When the installation frame angle is adjusted, the spiral drum will still operate at the mining distance above or below the open-pit coal mine. At this time, the second hydraulic cylinder is controlled to change the rotation angle of the convex bearing seat by bending and stretching. When the rotation angle of the convex bearing seat is changed, the spiral drum, fixed shaft, concave wheel and driven gear are driven to rotate relative to the driving gear and arc groove respectively. The left and right rotation angles of the spiral drum are adjusted to facilitate contact mining above or below the open-pit coal mine.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the continuous mining equipment and operating method for thin layers in open-pit coal mines,

[0033] (1) This case solves the problem of the existing open-pit coal mine thin-layer coal mining machine loading coal into the scraper conveyor by the following components in the drive adjustment assembly: coal hopper, drive motor, lower coal sweeping disc, hollow coal hopper, rotating frame, coal ladder, hollow protrusion, slide bar, connecting spring and groove plate. The coal hopper is loaded into the scraper conveyor by the spiral blades on the drum. Its loading performance is poor, the coal circulation is serious, and it is easy to cause excessive coal crushing and a significant reduction in coal block size. When the coal block is mined and falls, some of the coal block falls directly into the coal hopper or onto the coal ladder. The coal block falling onto the coal ladder squeezes the coal ladder and simultaneously exerts force on the connecting spring and hollow protrusion, causing the coal block falling onto the coal ladder to slide and be transported into the coal hopper. The coal block entering the coal hopper is directly transported into the main body through the drive motor and the lower coal sweeping disc to ensure the integrity of the coal block transport.

[0034] (2) By adjusting the drive adjustment component set in the mining and conveying structure, the angle of the drum of the existing open-pit coal mine thin-layer coal mining machine is not adjustable, which makes the coal seam excavation and cutting incomplete, resulting in missed mining and affecting the coal output rate. When it is necessary to mine the coal block above or below, the first hydraulic adjustment cylinder is controlled to perform bending or stretching movements to drive the installation frame to tilt at an angle. When the installation frame is under force and tilted at an angle, the lower coal ladder, lower coal bucket, universal drive shaft, second ball rod and ball seat are simultaneously under force and tilted at an angle. When the spiral drum and the cutting teeth carried on the surface come into contact with the upper coal thin layer, the motor is driven again to run to mine the upper coal thin layer of the open-pit coal mine.

[0035] (3) By adjusting the coal mining components set in the mining and conveying structure, the above problems can be solved. When the installation frame angle is adjusted, the spiral drum will still operate at the mining distance above or below the open-pit coal mine. At this time, the second hydraulic cylinder is controlled to change the rotation angle of the convex bearing seat by bending and stretching. When the rotation angle of the convex bearing seat is changed, the spiral drum, fixed shaft, concave wheel and driven gear will be driven to rotate relative to the driving gear and arc groove respectively. The left and right rotation angles of the spiral drum can be adjusted to facilitate contact mining above or below the open-pit coal mine.

[0036] (4) By using the driven gear and the driving gear in the drive adjustment component, the low efficiency of single spiral drum mining of coal blocks is solved. When the driving gear is subjected to force and rotates, it synchronously drives the driven gear to rotate relative to the force and rotate relative to the force, thereby increasing the coal block mining speed and efficiency. At the same time, through the 1 set of spiral drums, not only is the mining area expanded, but the mining volume is also increased synchronously. Attached Figure Description

Detailed Implementation

[0053] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figure 1-15 This invention provides a technical solution: a continuous mining equipment for thin layers in open-pit coal mines, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a basic drive power supply structure 1, which includes a drive component body 101 as the base. A main body 102 is fixedly installed on top of the drive component body 101, and a power supply component 103 is fixedly installed on top of the main body 102. A recessed block 104 is fixedly installed on one side of the power supply component 103, and a through plate 106 with welding holes 105 is welded and fixedly installed on the inner side of the recessed block 104. A powerful drive motor 107 is fixedly installed inside the through plate 106 and the recessed block 104. The drive component body 101, the main body 102, and the power supply component 103 are all set using existing technical structures, which effectively drive the overall equipment and provide power when using existing technical structures.

[0055] Furthermore, in the above-mentioned scheme, a through-hole seat 108 with an internal mounting bearing is installed through the output end of the high-power drive motor 107. A first spherical rod 109 is fixedly installed on the surface of the through-hole seat 108 by welding a connecting block. At the same time, the other end of the first spherical rod 109 is welded and fixed to the welding hole 105. A second spherical rod 1010 with a hollow internal structure is installed inside the through-hole seat 108. One end of the second spherical rod 1010 is welded and fixed to the output end of the high-power drive motor 107. At the same time, another mounting bearing that is matched and connected to the components of the adjusting mining and conveying structure 2 is also fixedly installed inside the second spherical rod 1010. A conveying pipe 1011 with a connecting hole is embedded and installed through one side of the main body 102. There are four first spherical rods 109. The multiple first spherical rods 109 effectively provide a stable and secure fixed installation for the high-power drive motor 107.

[0056] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, a regulating mining and conveying structure 2 is fixedly installed on one side of the driving power supply structure 1. The regulating mining and conveying structure 2 includes a driving regulating component 201 that is installed in conjunction with the coal mining component 202. The driving regulating component 201 includes a mounting frame 2011 with a hollow internal structure. Arc-shaped grooves 2012 are provided through the two surfaces of the mounting frame 2011. A spherical seat 2013 with an internal bearing is welded and fixedly installed on one side of the mounting frame 2011. The spherical seat 2013 is connected to the mounting frame 2011 through a through hole. Inside 2013, a universal drive shaft 2014 extending into the mounting frame 2011 is installed via a bearing. The arc-shaped groove 2012 has two sets of four grooves. When the above structure is symmetrically arranged, it effectively facilitates the through-guided adjustment of the fixed shaft 2017. Furthermore, the spherical seat 2013 and the second spherical rod 1010 constitute a spherical universal joint structure in the prior art. When the above two constitute a spherical universal joint structure, it effectively facilitates the relative rotation adjustment between the second spherical rod 1010 and the spherical seat 2013.

[0057] Furthermore, in the above scheme, one end of the universal drive shaft 2014 is equipped with a drive gear 2015 installed inside the mounting frame 2011 via a bearing seat, and the drive gear 2015 meshes with the driven gear 2016. At the same time, a fixed shaft 2017 extending through the mounting frame 2011 is welded and fixedly installed on both sides of the driven gear 2016. A concave wheel 2018 that slides and adjusts with the arc-shaped groove 2012 is fixedly installed through the surface of the fixed shaft 2017. There is one set of driven gears 2016, which achieves relative meshing adjustment. Similarly, there is one set of fixed shafts 2017, and a concave wheel 2018 with an internal mounting bearing is installed through the surface of each fixed shaft 2017. The concave wheel 2018 facilitates the synchronous force-driven rotation adjustment of the fixed shaft 2017 and the driven gear 2016.

[0058] Furthermore, in the above-mentioned scheme, the mounting frame 2011 is fixedly installed on one side of the through seat 108 via a movable connector and a first hydraulic adjusting cylinder 2019, and the other end of the universal drive shaft 2014 passes through the second spherical rod 1010 and is fixedly installed at the output end of the powerful drive motor 107. Simultaneously, the second spherical rod 1010 is rotatably connected to the spherical seat 2013. A bearing plate 20110 with an arc-shaped groove 2012 is welded and fixedly installed on one side of the mounting frame 2011, and a lower bearing plate 20110 is fixedly installed below the bearing plate 20110. The lower coal hopper 20111 has a lower coal sweeping disc 20114 rotatably mounted inside it via a drive motor 20113. A hollow coal discharge pipe 20115 is rotatably mounted on one end of the lower coal hopper 20111 via a connecting pin, and the other end of the hollow coal discharge pipe 20115 is also rotatably connected to the conveying pipe 1011 via a connecting pin. The above-mentioned components constitute a rotation adjustment structure, which effectively changes the up-down rotation angle of the mounting frame 2011.

[0059] Furthermore, in the above scheme, a rotating frame 20116 is welded and fixedly installed on one side above the coal hopper 20111, and the rotating frame 20116 is rotatably connected to one end of the coal ladder 20117 via a connecting pin. Simultaneously, a hollow protrusion 20118 is welded and fixedly installed on one side of the coal ladder 20117. The hollow protrusion 20118 passes through the slide rod 20119 and the connecting spring 20120 and slides inside the grooved plate 20112. Both ends of the slide rod 20119 are connected to the grooved plate 20112. The internal fixed installation, and one end of the connecting spring 20120 is fixedly installed below the hollow protrusion 20118, and the other end of the connecting spring 20120 is fixedly installed inside the lower part of the groove plate 20112. The above components constitute an elastic adjustment structure. The elastic adjustment structure constituted by the above components can effectively change the elastic lifting range distance of the coal ladder 20117. By changing the elastic lifting range distance of the coal ladder 20117, the conveying and unloading of coal blocks and the impact buffering can be effectively facilitated.

[0060] like Figure 14 and Figure 15 As shown, the coal mining assembly 202 includes a convex bearing seat 2021 that is connected to the bearing plate 20110. A through-hole recess 2022 is welded and fixedly installed on the upper and lower sides of the convex bearing seat 2021. The through-hole recess 2022 is rotatably connected to one end of a second hydraulic cylinder 2023 via a connecting pin. The other end of the second hydraulic cylinder 2023 is fixedly installed on the surface of the bearing plate 20110 via a rotating connecting seat. A spiral roller 2024 with cutting teeth 2025 is fitted onto the surface of the convex bearing seat 2021. One end of the spiral roller 2024 is welded and fixed to a fixed shaft 2017. These components allow for left-right rotation adjustment. This rotation adjustment effectively changes the synchronous rotation angle of the convex bearing seat 2021 and the spiral roller 2024. By changing the synchronous rotation angle of the spiral roller 2024, it facilitates rotational contact mining between the spiral roller 2024 and the uppermost and lowermost thin layers of the open-pit coal mine.

[0061] A method for operating thin-layer coal seams in open-pit coal mines:

[0062] First: The overall device drive:

[0063] (1): When the open-pit coal mine thin layer needs to be mined, the operator starts the kinetic energy supply component 103 to drive the drive component body 101 to work. When the drive component body 101 moves the whole equipment to the position of the open-pit coal mine thin layer to be mined, the operator continues to control the drive component body 101 to work so that the spiral drum 2024 and the cutting teeth 2025 on the surface of the spiral drum 2024 come into contact with the open-pit coal mine thin layer, thereby controlling the powerful drive motor 107 to work.

[0064] Second: Thin-layer mining operations in open-pit coal mines under horizontal conditions:

[0065] (1): When the powerful drive motor 107 is running, it drives the universal drive shaft 2014 to rotate under force. When the universal drive shaft 2014 is rotating under force, it drives the driven gear 2016 to rotate relative to each other through the drive gear 2015. Under the relative rotation and meshing, it drives the spiral drum 2024 and the cutting teeth 2025 on the surface to rotate relative to each other, thereby mining the thin layer of open-pit coal mine. The coal blocks that are mined fall onto the lower coal hopper 20111 and the lower coal ladder 20117. At this time, the lower coal ladder 20117 is under force and moves, so that the coal blocks falling on the surface are synchronously transported to the lower coal hopper 20111. Under the operation of the lower coal sweeping disc 20114 and the drive motor 20113, the coal blocks are transported to the main body 102 through the conveying pipe 1011.

[0066] Third: Thin-layer mining operations in open-pit coal mines with a certain angle of inclination above or below:

[0067] (1): When it is necessary to mine the thin coal layer above the open-pit coal mine, the operator first controls the first hydraulic regulating cylinder 2019 to perform bending or stretching movements to drive the mounting frame 2011 to tilt at an angle. When the mounting frame 2011 is tilted at an angle, the lower coal ladder 20117, lower coal hopper 20111, universal drive shaft 2014, second ball rod 1010 and ball seat 2013 are tilted at an angle. When the spiral roller 2024 and the cutting teeth 2025 carried on the surface come into contact with the thin coal layer above, the motor 107 is driven again to run to mine the thin coal layer above the open-pit coal mine.

[0068] (2): When the angle of the mounting frame 2011 is adjusted, the spiral drum 2024 will still operate at the mining distance above or below the open-pit coal mine. At this time, the second hydraulic cylinder 2023 is controlled to change the rotation angle of the convex bearing seat 2021 by bending and stretching. When the rotation angle of the convex bearing seat 2021 is changed, the spiral drum 2024, fixed shaft 2017, concave wheel 2018 and driven gear 2016 are driven to rotate relative to the driving gear 2015 and arc groove 2012 respectively. The left and right rotation angles of the spiral drum 2024 are changed to facilitate contact mining above or below the open-pit coal mine.

10. A method for operating thin-layer coal seams in open-pit coal mines, characterized in that: First: The overall device drive: (1): When the thin layer of open-pit coal mine needs to be mined, the operator starts the kinetic energy supply component (103) to drive the drive component body (101) to operate. When the drive component body (101) moves the entire equipment to the location of the thin layer of open-pit coal mine to be mined, it continuously controls the drive component body (101) to operate so that the spiral drum (2024) and the cutting teeth (2025) carried on the surface of the spiral drum (2024) come into contact with the thin layer of open-pit coal mine, thereby controlling the operation of the powerful drive motor (107): Second: Thin-layer mining operations in open-pit coal mines under horizontal conditions: (1): When the powerful drive motor (107) is running, it drives the universal drive shaft (2014) to rotate under force. When the universal drive shaft (2014) rotates under force, it drives the driven gear (2016) to rotate relative to each other through the active gear (2015). Under the relative rotation and meshing, it drives the spiral drum (2024) and the cutting teeth (2025) carried on the surface to rotate relative to each other, thereby mining the thin layer of open-pit coal mine. The coal blocks that fall off the mining fall onto the lower coal hopper (20111) and the lower coal ladder (20117). At this time, the lower coal ladder (20117) moves under force, causing the coal blocks that fall on the surface to be synchronously transported to the lower coal hopper (20111) through the lower coal sweeping disc (20114) and the drive motor (20113). The coal blocks are then transported to the main body (102) through the conveying pipe (1011). Third: Thin-layer mining operations in open-pit coal mines with a certain angle of inclination above or below; (1): When it is necessary to mine the thin coal layer above the open-pit coal mine, the operator first controls the first hydraulic regulating cylinder (2019) to perform bending or stretching movements to drive the mounting frame (2011) to tilt at an angle. When the mounting frame (2011) is tilted at an angle, the lower coal ladder (20117), lower coal hopper (20111), universal drive shaft (2014), second ball rod (1010) and ball seat (2013) are tilted at an angle. When the spiral roller (2024) and the cutting teeth (2025) carried on the surface come into contact with the thin coal layer above, the motor (107) is driven again to run to mine the thin coal layer above the open-pit coal mine. (2): When the angle of the mounting frame (2011) is adjusted, the spiral drum (2024) will still operate at the mining distance above or below the open-pit coal mine. At this time, the second hydraulic cylinder (2023) is controlled to change the rotation angle of the convex bearing seat (2021) by bending and stretching. When the rotation angle of the convex bearing seat (2021) is changed, the spiral drum (2024), fixed shaft (2017), concave wheel (2018) and driven gear (2016) are driven to rotate relative to the driving gear (2015) and arc groove (2012) respectively. The left and right rotation angles of the spiral drum (2024) are adjusted to facilitate contact mining above or below the open-pit coal mine.
