Description

Technical Field

[0001] The invention relates to the field of coal mine transportation, and in particular to a comprehensive mechanized coal mining automatic transportation device for coal mines. Background Art

[0002] The automatic conveying equipment for comprehensive mechanized coal mining in coal mines can continuously and stably transport the collected coal materials from the mining point, avoiding the time delay caused by manual handling or traditional inefficient transportation methods. For example, in large-scale mining operations, belt conveyors can work uninterruptedly, closely linking the coal mining process with the transportation process, minimizing the downtime of coal mining operations, and significantly improving the overall efficiency of coal mining.

[0003] However, the existing conveying equipment can only transport coal in one direction, lacks flexibility, and cannot be adjusted in time when facing different working surfaces. And because the conveyor is basically fixed, when the existing conveying equipment is rotating, the operator needs to rotate the conveying equipment as a whole. This process will affect the stability of the conveying equipment and requires further adjustment during subsequent work. Different areas in coal mining have transportation ports at different angles. The fixed design of traditional conveying equipment makes it difficult to accurately connect the conveyor belt and the transportation port, which can easily cause coal to spill and accumulate, waste resources and pose a safety hazard. At the same time, the existing belt conveyor is large in size and the underground space in the coal mine is small. It is difficult to install and is prone to collision and friction with surrounding equipment and tunnel walls during operation, increasing the risk of equipment damage and interference with mining operations.

[0004] Therefore, the transportation equipment that can only connect to a single working face can no longer meet the current coal mining work. Nowadays, simultaneous mining of multiple working faces is becoming more and more common. Traditional transportation equipment cannot receive and transport coal from multiple working faces at the same time, resulting in the need to equip each working face with a separate conveyor or use inefficient manual transfer methods, which increases mining costs and time costs and is not conducive to efficient coal mining. Summary of the invention

[0005] Based on this, it is necessary to provide a comprehensive mechanized coal mining and automatic conveying equipment for coal mines in response to the existing technical problems.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] refer to Figures 1 to 10 A coal mine comprehensive mechanized coal mining automatic conveying equipment, comprising a conveying equipment body 1, the conveying equipment body 1 comprises a conveyor belt 2, and also comprises:

[0037] A reversing mechanism 3 is arranged at the upper end of the conveyor belt 2;

[0038] The self-adjusting material receiving mechanism 8 is arranged above the conveyor belt 2 and connected to the output end of the reversing mechanism 3, and includes a fork-shaped base 9, a conveyor belt 14, a deformation mechanism 18, two main rollers 15, four tensioning rollers 16 and two conveying rollers 17. The fork-shaped base 9 is fixedly connected to the output end of the reversing mechanism 3, the conveyor belt 14 is arranged on the side of the fork-shaped base 9 away from the conveyor belt 2, the deformation mechanism 18 is connected to the fork-shaped base 9 and drives the conveyor belt 14 to deform, and the two main rollers 15 are rotatably arranged above the fork-shaped base 9 (reference Figure 3 ), two tensioning rollers 16 are respectively arranged below each main roller 15, and two conveying rollers 17 are rotatably arranged below the fork-shaped base 9. The two main rollers 15, the four tensioning rollers 16 and the two conveying rollers 17 are connected by a conveyor belt 14.

[0039] When the device is in operation, when the conveying equipment body 1 moves to the side of the working surface and the conveying equipment body 1 is positioned, the operator first starts the reversing mechanism 3 to align the conveyor belt 14 with the corresponding working surface, and then starts the self-adjusting material collecting mechanism 8 to move the conveyor belt 14. During the movement of the conveyor belt 14, the collected coal will move along the conveyor belt 14 to the conveyor belt 2, and finally be collected by the conveying equipment body 1 via the conveyor belt 2.

[0040] During this process, in order to enable the conveyor belt 14 to cope with the collection of different working surfaces without changing the conveying equipment body 1, the deformation mechanism 18 is activated to change the conveying distance of the conveyor belt 14, thereby improving the overall stability of the device.

[0041] In order to supplement the specific structure of the reversing mechanism 3, the following features are also specifically provided:

[0042] The reversing mechanism 3 includes a main frame 4, a main gear ring 5, a main motor 6 and a main gear 7. The main frame 4 is arranged above the conveyor belt 2 and is fixedly connected to the bracket beside the conveyor belt 2 (refer to Figure 1 ), the main motor 6 is fixedly arranged above the main frame 4 through the motor frame (reference Figure 2 ), the main gear 7 is coaxially connected to the output end of the main motor 6 (reference Figure 2 and Figure 4 ), the main gear ring 5 is coaxially connected to the main frame 4 and meshes with the main gear 7, and the main gear ring 5 is fixedly connected to the fork-shaped base 9. After the main motor 6 is started, the main motor 6 will drive the main gear ring 5 to rotate through the main gear 7, and the main gear ring 5 will drive the fork-shaped base 9 to move, thereby realizing the transportation of coal resources in different working surfaces.

[0043] In order to drive the conveyor belt 14 to rotate, the following features are also specifically provided:

[0044] The self-adjusting material receiving mechanism 8 also includes a power motor 10, a telescopic frame 13, a power gear 11 and a conveying gear 12. The telescopic frame 13 is fixedly connected to the fork-shaped base 9 and the telescopic end is fixedly connected to the power motor 10 through the motor frame (refer to Figure 2 and Figure 6 ), the power gear 11 is coaxially connected to the output end of the power motor 10, and the conveying gear 12 is meshed with the power gear 11 and coaxially connected to a conveying roller 17. After the power motor 10 is started, the power motor 10 drives the conveying gear 12 to rotate through the power gear 11, and the conveying gear 12 drives the conveyor belt 14 to rotate through the conveying roller 17.

[0045] In order to facilitate the movement of materials on the conveyor belt 14 to the upper end of the conveyor belt 2 when the conveyor belt 14 rotates, even if the length of the conveyor belt 14 changes, the following features are also specifically provided:

[0046] The self-adjusting material receiving mechanism 8 also includes a material guiding inclined plate 42, two material guiding inclined plates 43 and two material guiding straight plates 44. The material guiding inclined plate 42 is fixedly connected to one end of the fork-shaped base 9 close to the conveyor belt 2 (refer to Figure 1 and Figure 3 ), the two material leading inclined plates 43 are respectively fixedly connected to the upper ends of the material guiding inclined plates 42, the material leading inclined plates 43 are slidably connected to the upper end of the conveyor belt 14, the two material leading straight plates 44 are respectively slidably connected to the sides away from the two material leading inclined plates 43, the two material leading straight plates 44 are respectively against the side edges of the conveyor belt 14 and are rotatably connected to the two ends of the main roller 15 away from the conveyor belt 2. After the length of the conveyor belt 14 changes, the two material leading straight plates 44 will move along the two material leading inclined plates 43, during which the side edges of the conveyor belt 14 will still be against the material leading inclined plates 43 and the material leading straight plates 44, at this time, when the coal resources move to the upper end of the conveyor belt 14, the coal resources will be limited by the material leading inclined plates 43 and the material leading straight plates 44 as the conveyor belt 14 moves, and finally the coal resources will fall onto the conveyor belt 2 along the material guiding inclined plates 42.

[0047] In order to facilitate the uniform laying of coal resources on the conveyor belt 14 and improve the carrying capacity of the conveyor belt 14, the following features are also specifically set:

[0048] The self-adjusting material receiving mechanism 8 also includes a stirring roller 46 and a plurality of supporting rollers 45. The stirring roller 46 is arranged at the upper end of the conveyor belt 14 and its two ends are rotatably connected to the side close to the two material guiding straight plates 44 (refer to Figure 1 and Figure 3 ), the stirring roller 46 is formed with a plurality of stirring flanges at equal angles along the circumferential direction, a plurality of support rollers 45 are rotatably arranged in an array at equal intervals at the lower end of the conveyor belt 14 and the two ends are rotatably connected with the two material-introducing straight plates 44, and the upper ends of the plurality of support rollers 45 are rotatably opposed to the lower end of the conveyor belt 14. When the coal resources are placed at the upper end of the conveyor belt 14, the coal resources will accumulate under the action of gravity, and at this time, the plurality of support rollers 45 will support the conveyor belt 14 to prevent the conveyor belt 14 from being suppressed by the locally overweight coal resources and unable to rotate. Then, when the coal resources move to the lower end of the stirring roller 46, the locally overweight coal resources will be evenly spread by the stirring roller 46 along the rotation direction of the conveyor belt 14, reducing the pressure-bearing capacity of the conveyor belt 14.

[0049] In order to supplement the structure of the deformation mechanism 18, the following features are also specifically provided:

[0050] The deformation mechanism 18 also includes a dual-axis motor 19, two active bevel gears 25, two driven bevel gears 33 and two bevel gear racks 34. The dual-axis motor 19 is arranged below the conveyor belt 14 and is fixedly connected to the fork-shaped base 9 through the motor rack (refer to Figure 2 and Figure 7), two bevel gear racks 34 are respectively arranged at both ends of the dual-axis motor 19 and are fixedly connected to the fork-shaped base 9 through a pad, two active bevel gears 25 are respectively fixedly connected to the two output ends of the dual-axis motor 19 coaxially, and two driven bevel gears 33 are respectively meshed with the two active bevel gears 25 and are rotationally connected to the corresponding bevel gear racks 34. After the dual-axis motor 19 is started, the dual-axis motor 19 will drive the two driven bevel gears 33 to rotate through the two active bevel gears 25.

[0051] In order to drive the tensioning roller 16 to move, the following features are also specifically provided:

[0052] The deformation mechanism 18 also includes four reversing gears 35, four driving pulleys 36, four first belts 37, four driven pulleys 38, four tensioning gears 39, eight tensioning racks 40 and eight tensioning frames 41. The four reversing gears 35 are respectively rotatably connected to the two ends of the motor frame of the dual-axis motor 19, and a reversing gear 35 located at the end of the motor frame of the dual-axis motor 19 is coaxially fixedly connected to the corresponding driving bevel gear 25 (refer to Fig.10 ), the four driving pulleys 36 are respectively connected to the four reversing gears 35 coaxially, and the two ends of the four tensioning rollers 16 are respectively connected to a tensioning frame 41 for rotation (reference Figure 8 ), eight tensioning racks 40 are respectively fixedly connected to eight tensioning frames 41, and the eight tensioning racks 40 are respectively slidably connected to the fork-shaped base 9 through tooth seats, and a tensioning gear 39 is rotatably provided on the side close to the tensioning rack 40 at the same end of the tensioning roller 16, and the tensioning gear 39 is meshed with two adjacent tensioning racks 40, and four driven pulleys 38 are respectively coaxially fixedly connected to the four tensioning gears 39, and the four driven pulleys 38 are respectively connected to the four driving pulleys 36 through four first belts 37. After the dual-axis motor 19 is started, the dual-axis motor 19 will drive the driving pulley 36 to rotate through the reversing gear 35, and the driving pulley 36 will drive the driven pulley 38 to rotate through the first belt 37, and the driven pulley 38 will drive the corresponding tensioning rack 40 to move through the tensioning gear 39, and the tensioning rack 40 will drive the tensioning roller 16 to move through the tensioning frame 41.

[0053] When the length of the conveyor belt 14 needs to be reduced, the two adjacent tensioning rollers 16 move away from each other. When the length of the conveyor belt 14 needs to be increased, the two adjacent tensioning rollers 16 move closer to each other, thereby ensuring that the conveyor belt 14 remains taut at all times. During this process, the conveying roller 17 will also move in the vertical direction, and the corresponding main roller 15 will also move in the horizontal direction. The specific movement process will be explained later.

[0054] In order to drive the conveying roller 17 to move, the following features are also specifically provided:

[0055] The deformation mechanism 18 also includes two conveying frames 20, two screw seats 21, two screw sleeves 24 and two screw rods 23. The two conveying frames 20 are respectively arranged on both sides of the conveyor belt 14, and the conveying frames 20 are rotatably connected to the ends of the two conveying rollers 17 (refer to Figure 7 ), two screw seats 21 are respectively fixedly connected to two conveying frames 20, two screw sleeves 24 are respectively fixedly connected to two screw seats 21, two screw rods 23 are respectively threadedly connected to two screw sleeves 24, and two screw rods 23 are respectively coaxially fixedly connected to two driven bevel gears 33. After the driven bevel gear 33 rotates, the driven bevel gear 33 will drive the screw sleeve 24 to move through the screw rod 23, and the screw sleeve 24 will drive the conveying frame 20 to move through the screw seat 21, and after the conveying frame 20 moves, it will drive the conveying roller 17 rotatably connected thereto to move.

[0056] In order to limit the movement of the screw seat 21, the following features are also specifically provided:

[0057] The deformation mechanism 18 further includes two slides 22, which are fixedly connected to the lower end of the fork-shaped base 9, and the two sides of the screw seat 21 are respectively slidably connected to the slides 22, and the upper end of the screw rod 23 is rotatably connected to the fork-shaped base 9, and the lower end is rotatably connected to the slides 22. When the screw rod 23 rotates, the slides 22 limit the two sides of the screw seat 21 to prevent the screw seat 21 from being unable to move normally.

[0058] In order to drive the main roller 15 to move and thereby realize the extension and contraction of the conveyor belt 14, the following features are specifically provided:

[0059] The deformation mechanism 18 also includes two first pulleys 26, two second belts 27, two second pulleys 28, two stretching gears 29, two stretching racks 30, two positioning sleeves 31 and two sliding rods 32. The two first pulleys 26 are respectively coaxially fixed to the two active bevel teeth 25 (refer to Fig.10 ), the two positioning sleeves 31 are respectively connected to the fork-shaped base 9 and have an avoidance groove formed on the upper end (reference Figure 3 ), one end of the two sliding rods 32 is respectively connected to the two positioning sleeves 31 for sliding connection, and the other end is connected to the end of the main roller 15 away from the conveyor belt 2 for rotation, and the two stretching racks 30 are respectively connected to the upper ends of the two sliding rods 32 (refer to Figure 3 ), two stretching gears 29 are respectively rotatably arranged on the upper ends of the two stretching racks 30 through tooth seats and meshed with the two stretching racks 30, two second pulleys 28 are respectively coaxially fixedly connected with the two stretching gears 29, and the two second pulleys 28 are respectively connected to the two first pulleys 26 through two second belts 27 (reference Figure 5 , Fig. 9 and Fig.10When the driven bevel gear 33 rotates, the driven bevel gear 33 drives the two first pulleys 26 to rotate, and the two first pulleys 26 drive the two second pulleys 28 to rotate through the two second belts 27. The two second pulleys 28 drive the two stretching racks 30 to move through the two stretching gears 29. The two stretching racks 30 drive the two main rollers 15 to move through the two sliding rods 32. When the main rollers 15 move, they drive the conveyor belt 14 to deform.

[0060] The working principle of the device is that when the device is in operation, after the conveying equipment body 1 moves to the side of the working surface and the conveying equipment body 1 is positioned, the operator first starts the main motor 6 to drive the fork-shaped base 9 to rotate, so as to align the conveyor belt 14 with the corresponding working surface. When it is necessary to reduce the length of the conveyor belt 14, the two adjacent tensioning rollers 16 move away from each other, the conveying roller 17 moves downward, and the sliding rod 32 moves in a direction close to the positioning sleeve 31; when it is necessary to increase the length of the conveyor belt 14, the two adjacent tensioning rollers 16 move closer to each other, the conveying roller 17 moves upward, and the sliding rod 32 moves in a direction away from the positioning sleeve 31, thereby ensuring that the conveyor belt 14 is always kept taut.

[0061] After the length of the conveyor belt 14 is changed, the two material guide straight plates 44 will move along the two material guide inclined plates 43. During this process, the side of the conveyor belt 14 will still be against the material guide inclined plates 43 and the material guide straight plates 44. At this time, when the coal resources move to the upper end of the conveyor belt 14, the coal resources will accumulate under the action of gravity. At this time, a number of support rollers 45 will support the conveyor belt 14 to prevent the conveyor belt 14 from being suppressed by the locally heavy coal resources and unable to rotate. Subsequently, when the coal resources move to the lower end of the stirring roller 46, the locally high coal resources will be evenly spread out by the stirring roller 46 along the rotation direction of the conveyor belt 14, reducing the pressure-bearing capacity of the conveyor belt 14. Subsequently, the coal resources will be limited by the material guide inclined plates 43 and the material guide straight plates 44 as the conveyor belt 14 moves. Finally, the coal resources will fall onto the conveyor belt 2 along the material guide inclined plates 42.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
